The Electrical Power System (EPS) is an electronic circuit board that is designed to supply and manage the energy in an efficient way. This paper describes the design architecture and circuits involved for an EPS deployed in the ISTsat ONE nano-satellite project. The EPS generates energy through the solar panels which is stored in the battery, and then using DC-DC switching voltage regulators, convert to the final voltage of +3.3 V and +5 V, supplying these voltage rails for rest of the subsystems of the satellite. This architecture meets the performance and size requirements of Cubesat architecture. It implements Maximum Power Point Tracking mechanism to achieve maximum efficiency in the conversion the solar energy, a 20.8 Wh battery, solar panels and redundant circuitry that ensures power supply to the satellite. The EPS is a subsystem of the ISTsat ONE and as such it communicates with other subsystems present in the satellite, by sending data logs, error warnings as well as receiving commands Keywords— EPS, Space, CubeSat, Nano satellite, ISTsat-ONE, Power System, DC/DC Converter, Solar Panel, Energy Management Introduction. Man has put satellites on orbit to address the ever growing necessity of connecting every part of the world. The Satellites have various purposes such as telecommunication, space exploring, military purposes, weather forecast, among others. The ISTsat ONE is a nano-satellite standard 10 cm cube and its main purpose is to support the Automatic Dependent Surveillance Broadcast system (ADS-B) via satellite, receiving the identification and position of the airplane broadcasted by the plane and relay it back to a ground station on Earth. This solution addresses the issue of the airplanes loosing contact with the ground stations, and so failing to report their position, leading to missing airplane cases [1][2]. This project is inserted in the Fly Your Satellite Program from European Space Agency, which it's main purpose is to provide the opportunity to students in the university to develop and launch a satellite, at the same time providing a mission service. The ISTsat ONE is divided into subsystems, namely the Attitude Determination and Control System (ADCS) which is responsible for determining in real time position and satellite framework with the Earth; Communications (COM) which is the system responsible for all digital communications between the satellite and the ground stations; Command and Data Handling (CDH) that performs the processing of data provided by the onboard components, the responsibility to maintain the proper functioning of the satellite; Telemetry Tracking and Command system (TT&C) gathers all the relevant information of the satellite (position, attitude, systems status, and more...) and sends the collected data through a dedicated frequency back to the Ground Station; and the EPS. These subsystems perform full control of the Space-Craft (S/C), an additional sub-system is deployed to perform a scientific experiment or a specific mission called the Payload. There are many risk factors in space that can jeopardize the S/C: space debris can hit the S/C, damaging the PV cells or internal circuitry, solar radiation, electromagnetic wave; and because there is no service or repair in space for a nano-satellite due to the incapability of fetching the satellite once deployed, the EPS must assure that power never fails under any circumstance. This feature is addressed with redundant circuitry and energy optimized operation modes. The design chosen to the EPS electric circuit is divided in four sections: the converters use to regulated power supply collected by solar panels, the architecture used to distribute or store the energy collected in the battery, the power distribution module that converter energy in regulated outputs use for power in all nano-satellites and the section devoted to the microcontroller used to collect measurements and carry out the monitoring of all EPS. I. FIRST EPS VERSION FOR ISTSAT ONE The presented project is based on the first EPS prototype (Figure 1) that was developed for the ISTsat ONE. At that time it accomplished the power supply requirements of the ISTsat ONE. Figure 1 – ISTsat ONE first EPS developed prototype [3]. This EPS features connection to five solar panels with three MPPT converters a battery charger, a boost converter to achieve 12 V, two Single Ended Primary Inductor Converters (SEPIC) to achieve 5 V and 3.3 V. This EPS also features redundancy for the final regulation. The implementation for this redundancy is by step-down the voltage supplied from higher voltage buses, as shown in Figure 2.

We consider a technologically backward country and analyse the implications on competitiveness and long-run growth of the quality content of traded goods. We build an endogenous growth model where quality improvements stem from research activity taking place in the R&D sector, and where the relative quality content of goods matter for export and import demand functions. We show that the possibility of an optimal growth with a balanced current account and no adverse terms-of-trade effects is closely related to the evolution of the country's technological distance with respect to the trade partner: with an unfavourable quality-dynamics the country cannot engage successfully in "non-price" competition. Thus, long-run growth is coupled with an adverse export to import ratio, and a balanced trade requires a continuous offsetting fall in relative prices, either through devaluations or wage deflations. We then allow for international knowledge spillovers that increase the productivity of labour resources devoted to research in a way which is proportional to the technological distance between the countries. We show that the greater the country's ability to absorb foreign knowledge and improve upon foreign technologies, the greater the gains in competitiveness, and the benefits to long-run growth. A numerical simulation confirms our findings.


This paper explores the potential externality of welfare payments under the Unemployment Insurance (UI) program during times of high job destruction rates and unemployment rates on the spread and mortality of COVID-19. Using data for all US counties over the year 2020 and applying a difference-in-difference identification strategy, we explore the potential effects of UI benefits on the spread of COVID-19. We find that each additional $1,000 increase in UI maximum benefit is associated with 0.03 fewer deaths and 3.9 fewer confirmed cases per 100,000 population. The results are quite robust across specifications and subsamples with larger effects observed among counties with a higher share of blacks and low educated individuals and among counties below-median of per capita income.


Steam railways were the standard log hauling technology throughout California in the 1880's and 1890's. Most of the old growth redwood of the sort depicted here has since been cut and today the industry relies largely on younger, smaller trees. within California lie some of the most diverse forests to be found anywhere in the world. Forty million acres (two-fifths of the state) bear forest cover. Included are the oldest known trees (whitebark pines), the largest (Sierra big trees), the tallest (coast redwood), and a remarkable pygmy forest where trees reach full maturity at heights of no more than six or eight feet. In addition to such scientific highlights, California forests are of vital importance as a source of wood products, as protective cover for major watersheds, as habitat for characteristic and important fish and wildlife, and as outdoor playgrounds for millions of people. About 16 million acres of commercial forest provide raw material for the production of lumber, plywood, pulp, and various other forest products. Each year about 900 million cubic feet of such products are removed from the forests to meet consumer needs for housing, packaging materials, and many other end uses. The industry is concentrated in a great horseshoe which extends northward along the coast from Santa Cruz County to the Oregon border, eastward to Modoc County, and thence south along the Sierra Nevada to Tulare County. Within this area, forest products industries provide annual employment for about 100,OOO people and generate annual payrolls of $1.25 billion. They provide the principal economic base for 16 of the state's 58 counties. Slightly more than half the commercial forest is publicly owned, most of it in National Forests. Only one-sixth of the commercial forest is owned by the forest products industry. The remainder is held by farm and other owners, much of it in small holdings of 20 to 80 acres. History


In this paper, we consider a slow fading Multiple Access Multiple Relay Channel (MAMRC) defined as follows: (1) Multiple statistically independent sources communicate with a single destination with the help of multiple half-duplex dedicated relays; (2) The links between the different nodes are independent, and subject to slow fading and additive white Gaussian noise; (3) Sources and cooperating relays interfere (non-orthogonal transmission); (4) No Channel State Information (CSI) at senders and perfect CSI at receivers is available and no feedback is allowed. We introduce an advanced Decode-and-Forward (DF) protocol, referred to as Dynamic Selective Decode and Forward (D-SDF), where each relay individually decides the end of its listening phase and the beginning of its cooperation phase based on a predefined selection strategy. We analyse the outage behavior of this protocol under the assumption that each relay sender employs joint network channel coding and each receiver implements joint network channel decoding, and demonstrate that D-SDF outperforms static SDF in a variety of transmission scenarios.


Whilst it is sometimes essential that a scene is well lit before image capture, too much light can cause exposure or glare-based problems. Typically, glare is introduced to images when the camera is pointed towards the light source, and results in a visible distortion in the image. In this paper, we analyse and identify images that contain the 'glare' property using the empirical Benford's Law. The experiment is performed on 1338 images, and extracts discrete wavelet High High (HH), High Low (HL) and Low High (LH) sub bands as raw data. The significant digit from each coefficient of all sub bands is then calculated. We then analyse the probability of occurrence of large digits against smaller digits to detect anomalies. All images containing these anomalies are further analysed for the identification of additional salient features. This analysis is performed in accordance with the Benford's Law plot and the help of probability intensity histogram and divergence. Our results indicate that 142 images have irregular Benford's Law curves. For most images, the irregularity occurs at the 5th digit. After visual examination, we have found the unbalanced light and high level of brightness in these images. To measure the intensity of light in an image, we compute the probability histogram of gray levels. These results also correlate with the irregular peak identified from the Benford's Law curves. In addition, the divergence is then computed, which shows the deviation between the actual Benford's Law curve and the Benford's Law graph of an image. Our proposed technique is novel and has a potential to be an image forensic tool for quick image analysis.


This paper adopted the researching data of 735 rural households in the west areas,by using analytic hierarchy process(AHP) to survey households' satisfaction empirically,in order to evaluate the supply effect.Research results showed that:the satisfaction of households on grid was the highest,secondly,in turn for roads,public security,information service facilities,social security,ecological environment protection,medical care,water facilities,public health,and education.The satisfaction on cultural undertakings,irrigation and water conservancy facilities and agricultural technology extension training was lower than the mean theory,which were the factors led the degree of satisfaction decreased.The main influence factors to the satisfaction came from roads,irrigation and water conservancy facilities,medical care,education and water facilities.Households' individual characteristics had no significant effects on public goods satisfaction.


This report analyzes the potential for production of synthetic lightweight aggregate (SLA) from a Texaco coal gasification solid residue. The objective of the project was to develop a replacement for conventional lightweight aggregates typically derived from expanded clays and shales or natural lightweight aggregates. The sequence of tests performed to develop SLA from slag began with the crushing of samples of slag, followed by either extrusion or pelletization. The level of clay binder required for sufficient aggregate strength was evaluated. Using a tube furnace, expansion characteristics were studied as a function of temperature and residence time. Next, a large batch of SLA was produced in a muffle furnace and used to form concrete test cylinders. The unit weight of the resultant concrete was 105 lb/ft{sup 3}, with a compressive strength of 3100 psi, which meets the requirements specified in ASTM C 330 for lightweight aggregate of a comparable density. When the same sequence of tests was performed using a slag from which the bulk of the char had been removed, the concrete test cylinders showed an improved relationship between strength and density. Based on the results of bench-scale tests and the similarity to conventional LWA production, the conceptual design ofmore » an SLA processing plant was formulated. A comparative estimate of operating costs was prepared by analyzing data from plants using clays and shales to produce lightweight aggregates. 24 refs., 15 figs., 17 tabs.« less


In 1913 Micoletzky described a new species of .mononchs, Mononchus bathybius, on the basis of one juvenile collected in the bottom mud of Atter Lake, Austria, at a depth of 107 m. He gave no illustrations. The description stressed the similarity to M. gerlachei de Man, 1904, the chief difference being the stomatal armature : a subventral tooth near the base of the mouth cavity, and several smaller teeth, the position of which was not indicated. In 1914 he gave a more detailed description with illustrations. The position of the tooth was now given as subdorsal; however, if Figures 26 a and 26 b were drawn from the same side (and this must be the case since the specimen is mounted on a thick glass slide so that it can be studied from one side only, and the head outline as given in Figure 26 a agrees with the outline as it is now, in a slightly flattened state) then the tooth is on the ventral side. Because of the presence of one basal tooth Cobb (1916) brought the species to the subgenus Iotonchus Cobb, 1916, raised to generic rank by Pennak(1953). Mulvey (1963) considered M. bathybius species inquirenda, because it was described from one juvenile. It should be noted that the genus Iotonchus is characterized by the presence of a single, dorsal tooth. De Coninck (1930) mentioned a from Belgium, but he gave no description nor illustrations. The holotype is present in Micoletzky's collection. Dr. G. Hartwich, Berlin, had the kindness to lend it to me. The slide is numbered 9 139 and bears the legend : Table 1 Dimensions of Mononchus bathybius Micoletzky, 1913 Own .measurements


Database servers are the most important servers your company owns. They store client details, financial information, human resource details — all the data that keeps your company in business and, as such, they need to be secure. This paper has been written to help database administrators, security professionals and risk framers understand the issues involved with database security and provide options and solutions when designing defensive strategies. The system structure of LogicSQL database and security strategy applications were described in this paper. It is independently developed based on the Linux high-level security database system.


The present invention relates to a thermoplastic bay (10) having a double settable composition glazing according to the performance required, and comprising in particular: • A glass / polycarbonate compound (11) on its outside, the glass layer (11 ' ) and the polycarbonate layer (11 ") being interconnected by a layer (12) reflective of type" stopsol "• a panel (13) of polycarbonate on its interior; said compound glass / polycarbonate (11) and said panel (13) of polycarbonate being separated by an air gap (14). This architecture allows to obtain a very significant weight gain (= 50%) while ensuring resistance to much higher impact (= 250 times ) and a residual deflection (f = 1.5 mm) constrained maximum pressure wave (+ 4500 / - 7000 Pa) vs a reference glass complex.


In the collaborative tagging system, tags of users contain rich information on personalized preference, and time stamps of users show their interest changes. Users' interest has the varied timeliness, but the existing recommendation algorithm fusing time information only emphasizes the short-term interest of users but fails to dig into the long-term stable interest of users and thus presents the low recommendation precision. In this paper, we propose a tag-based recommendation algorithm integrating short-term and long-term interests of users. The algorithm first builds the short-term and long-term interest characteristics of users based on tags according to the use frequency, time decay, life cycle and volatility; then it maps the characteristics to the resources tagged by the user to form a user-resource pseudo-scoring matrix. Finally, it calculates the set of the nearest neighbors of user with the matrix to give recommendations. The verification on the delicious data set shows that the algorithm improves recommendation precision and diversity compared with other classical algorithms.


Objective To explore a new effective method to treat cavernous hemangiomas on body surface of children. Methods Clinical study was carried out on 78 cases with cavernous hemangiomas on body surface from 1999 to 2005. A new method for treating cavernous hemangiomas with continuous wave Nd : YAG laser irradiation was tried after injection Xiaozhiling( a hemorrhoid eliminated Chinese remedy) into their deep part. Results Good results were found in all the patients after a follow-up of 1 to 3 years. There were 70 cases with complete remission (92. 3% ) and 6 cases with partial remission(7. 7% ). No recurence was occurred. Conclusions Due to selective action on the target tissue, simple manipulation, fewer complications and higher successful rate, laser irradiation combined with Xiaozhiling has been confirmed to be a valuable means of treating cavernous hemangiomas on body surface of children.


In this paper, a frequency-dependent implicit space mapping method is proposed for the prototyping of wideband microwave device. In the proposed method, frequency-dependent mapping is established between the fabricated device and a fast surrogate model. In this way, the practical variance of electromagnetic properties in a wide frequency range can be properly approximated. The parameter extraction process becomes more reliable, the runs of fabrication can be significantly reduced. To verify the proposed method, a wideband impedance transformer is fabricated and tested as an example. The testing results achieve design specification within only two fabrications.


It is my contention that Ridley Scott's film, GI Jane, starring Demi Moore, can be analyzed as a kind of argumentative essay in that it presents a thesis that it defends through the use of supporting arguments and supporting examples. In addition, I also believe it follows many of the basic critical thinking rules in the presentation of its message. In class, we read three very different argumentative essays written on the subject of women in combat. They are: "Most Oppose Women in Combat" by Suzanne Fields, "An Officer and a Feminist" by James M. Dubik, and "Arms and the Woman" by Lou Marano. Each of these essays illustrates a contrasting attitude towards the idea of women serving in combat in the US military. I believe Scott created GI Jane so that it would covers many of the issues raised by authors such as these in order to support his thesis: women should be allowed to serve in combat. What I would like to show is that Ridley Scott offers arguments and evidence through his film that directly support his thesis in ways that follow our course models. In order to do this, I will show how GI Jane takes into account both the pro and con arguments put forth in each of the three essays.


The study examines the features and process of social work supervision in Hong Kong. A successful client outcome is the main objective, but supervisors perceive supervision as a rational and systematic process, whereas supervisees expect emotional support and teamwork. The supervisory relationship is both personal and professional. Tension is reduced by the traditional Chinese cultural values of reciprocity: qing, yuan, and 'face'. The strategy of using supervisory authority is 'consensus by consultation and consent' — which reduces conflict and gains acceptance. The journey of this study charts the interactions among my personal, professional, and academic identities. In order to conduct the research, I have to be more 'academic'. However, without my professional experience, I could not interpret the information in a meaningful manner. When I reviewed the data on the effects of traditional Chinese values, my personal self was reminded that I am also Chinese and that I share these beliefs.


Using a Generalised-Hydrodynamic (GH) fluid model, we study the influence of strong coupling induced modification of the fluid compressibility on the dynamics of compressional Mach cones in a dusty plasma medium. A significant structural change of lateral wakes for a given Mach number and Epstein drag force is found in the strongly coupled regime. With the increase of fluid compressibility, the peak amplitude of the normalised perturbed dust density first increases and then decreases monotonically after reaching its maximum value. It is also noticed that the opening angle of the cone structure decreases with the increase of the compressibility of the medium and the arm of the Mach cone breaks up into small structures in the velocity vector profile when the coupling between the dust particles increases.


The present study was carried out to reveal the possibility of controlling the ignition delay of hydrogen-air mixtures by applying electric fields. A quiescent stoichiometric hydrogen-air mixture was ignited by a suddenly heated thin wire of nickel or tungsten. DC electric fields were applied between the wire and outer electrode plates parallel with the wire. The mean ignition delay was calculated stochastically from the measured ignition delays which scattered considerably. Both with the nickel wire and with the tungsten wire, positive voltages applied to the outer electrode plates resulted in almost the same change of the mean ignition delay ; The mean ignition delay showed a slight increase at the lower applied voltages, while it became very short at the highest applied voltages. When the nickel wire was used and negative voltages were applied, the mean ignition delay decreased even at the lower voltages. However, it showed little change with the tungsten wire and the negative applied voltages.


Purpose: Whole‐body patient models are needed for the assessment of organdoses in various CTimaging and external‐beam radiation treatment procedures. The Boundary REPresentation (BPRE) type of geometry offers greater control over the anatomical shapes and tissue/organ surfaces could be flexibly deformed. Currently tedious and time‐consuming manual adjustment is necessary. This paper discusses an automatic modeling method recently developed to create two adjustable adult male and female mesh models with dynamically deformable organs.Method and Materials: The algorithm for the development of the deformable RPI Adult Male/Female phantoms was implemented by MATLAB® 7.4. The anatomical mesh models were based the Anatomium™ 3D models whose organ geometries were morphed to agree within 0.5% with the ICRP reference male and female organ volume/mass data. These mesh morphing algorithms were used to automatically pre‐modify the dataset to have unique mesh information in each of organ boundaries and deform the whole meshes based on the ICRP volume/mass reference without unwanted surface overlapping through the special mesh overlap avoiding process. After the deformations, the RPI Adult Male/Female mesh models were transformed to the solid geometries through the voxelization process with 3.2 mm and 3.0 mm, respectively. Results: These phantoms have been used by transforming the solid geometries into the voxel domain that is compatible with well‐validated Monte Carlo radiation transport simulations such as MCNP, EGSnrc and GEANT4codes. Through these mesh deformation algorithms, complicated bone (cavity, spongiosa, and cortical bones) and muscle structures have been described in the RPI Adult Male/Female mesh models. Conclusion: This study has demonstrated the feasibility to create deformable RPI Adult Male/Female phantoms. These phantoms will be applied to various applications of including person specific adjustments depended on age, weight, and height changes.


OBJECTIVE: To study the main site of muscle-relaxation induced by sevoflurane (Sev). METHODS: 64 mice were randomly divided into intrathecal injection (it) group and intracerebroventricular injection (icv) group. Then it group and icv group were redivided into aCSF group (0.25 μL·g-1), Sev1 group (0.25 mg·g-1), Sev2 group (0.31 mg·g-1), Sev3 group (0.39 mg·g-1) with each group of 8 mice. The duration of injection was 10 s and acupuncture manipulation time lasted for 15 s. The grip strength of mice were recorded before administration and 5, 10, 15, 20, 25, 30 min after administration. RESULTS: Compared with aCSF group, the grip strength of mice in each group had reduced as the concentration of Sev increased, there was significant difference between Sev2 group and Sev3 group (P0.05 or P0.01). Compared with icv groups, the grip strength of mice in Sev2 group and Sev3 group of it group had reduced (P0.01). CONCLUSION: Intrathecal and intracerebroventricular injection of sevoflurane produce muscle relaxation effect in dose-dependent manner, especially in it group. It can be concluded that spinal cord is the main site of muscle-relaxation induced by sevoflurane.


Since modern times the science and ration have got married,which greatly promoted the growth of rationalism and utilitarianism and simultaneously accelerated the weakening of religion and theology.Along with the speedy development of science-tech and industrialization,human greediness and arrogance have got swelling and human-centralism has come up to prominence,which will inevitably destroy the harmonious co-existence of man and nature.Therefore,only when we break through the hindrance of human-centralism,transcend the traditional understanding of science-technology as the tools,equip our brains with the new ecological ethics,actively make exploration of the mode of scientific development and build up aesthetic standard of harmonious co-existence,can we effectively inhibit ecological degradation,sustain ecological balance and ultimately build up our common ecological homestead.


We propose locating a slotted conductor plate in close proximity to a bent monopole antenna in order to enhance the bandwidth, and clarify that impedance matching is achieved in a fractional bandwidth of about 50% with the plate at less than 0.3 wavelengths in length. The possibility of further downsizing is also shown.


English have told me that his translations are on a par with my originals. But I prefer to think they've made my novels better. I admit that some people, with dubious motives, have told me he's added things absent in the original, such as descriptions of sex. These people were ignorant of the fact that he and I have an agreement that he'll translate sex scenes in ways that will appeal to American readers, which is why the English and Chinese versions may seem different. Howard and I began our collaboration in 1988. We've exchanged more than a hundred letters and spoken innumerable times over the telephone. The sole purpose of such frequent contact is to perfect the English translations. Often, we confer over a phrase or an object with which he's unfamiliar. Sometimes, I have to call upon my primitive drawing skills to sketch something for him. From this you can see that he is not only a talented translator, but a serious and conscientious one. It's my good fortune to be able to work with someone like him.


We construct a smooth axially symmetric solution to the classical one phase free boundary problem in $\mathbb{R}^{n}$, $n\geq 3.$ Its free boundary is of "catenoid" type. This is a higher dimensional analogy of the Hauswirth–Helein–Pacard solution [18] in $\mathbb{R}^{2}$. The existence of such solution is conjectured in [18, Remark 2.4]. This is the 1st nontrivial smooth solution to the one phase-free boundary problem in higher dimensions.


Multi-model predictive control (Multi-MPC) of Hammerstein systems is developed using an included angle based weighting method, which takes advantage of the special structure of the Hammerstein models. The proposed weighting method can be calculated offline and has merely one tuning parameter. Thus it is comparatively intuitive and simple. What is more, it can coordinate local controllers effectively. A Lab-tank system which can be modeled into a Hammerstein model is investigated. Comparisons have been made with the proposed weighting method and traditional methods.


Multilevel thresholding is a popular image segmentation technique. However, computational complexity of multilevel thresholding increases very rapidly with increasing number of thresholds. Metaheuristic algorithms are applied to reduce computational complexity of multilevel thresholding. A new method of multilevel thresholding based on Moth-Flame Optimization MFO algorithm is proposed in this paper. The goodness of the thresholds is evaluated using Kapur's entropy or Otsu's between class variance function. The proposed method is tested on a set of benchmark test images and the performance is compared with PSO Particle Swarm Optimization and BFO Bacterial Foraging Optimization based methods. The results are analyzed objectively using the fitness function and the Peak Signal to Noise Ratio PSNR values. It is found that MFO based multilevel thresholding method performs better than the PSO and BFO based methods.

Objective: To investigate the effects of different antioxidant micronutrients(AM) combinations on the expression level of cytokines in Type 1 diabetic mice. Method:T1DM mice models were induced by intraperitoneal injection of multiple low dosages of streptozotocin(MLDS).The AM4 combination which includes selenium, vitamine E, vanadium and chromium and the AM6 combination which includes selenium, vitamine E, vanadium, chromium, niacinamide and alpha-lipoic acid were administered by i.g. for 7 w, once daily. The expression levels of cytokines IL-4,IL-6 and IL-12 of lymphocytes from peripheral blood were detected by flowcytometry (FCM). The level of blood glucose and the activity of GSH-Px were detected by biochemical methods. Results:Compared with model group, blood glucose of AM4 and AM6 group decreased significantly(P0.05)and GSH-Px activity increased significantly(P0.05). The expression levels in IL-4 in AM4 and AM6 group increased significantly(P0.05)and wasalso significantly different between groups(P0.05).The expression level of IL-6 in AM6 group decreased significantly(P0.05)compared with AM4 or model group. Compared with model group, the expression levels of IL-12 in AM4 and AM6 group were downword. Conclusion:Different combinations of AM decreased the level of blood glucose, enhanced the activity of blood GSH-Px, upregulated the expression level of IL-4 and downregulated the expression levels of IL-6 and IL-12 . The effect on the expression level of cytokines was more significant in AM6 group.


Background: Interventions that target blood pressure control and proteinuria, specifically interruption of the Renin-angiotensin-aldosterone system (RAAS), have been utilized in attenuating cardiovascular complications. Angiotensin receptor blockers (ARBs) have been reported to have certain advantages. The objective of the study was to evaluate and compare the utilization pattern and efficacy of different ARBs in patients with HTN and associated type-II diabetes. Methods: Hypertensive patients with or without type-II diabetes treated with ARB based regimen were selected.  The BP and 24 hours urinary albumin excretion were analysed at baseline and after three months of treatment. Results: Mean reduction in systolic blood pressure(SBP) was more with ARBs and calcium channel blocker(CCB) combination. Telmisartan alone and with ACEI reduced diastolic blood pressure (DBP) maximally in diabetic hypertensive patients. Proteinuria was significantly reduced with telmisartan (p<0.001) and olmesartan (p<0.05) based therapy. The side effects were minimal with ARB based therapy. Telmisartan was the costliest among all ARBs Conclusions: There was suboptimal use of combination therapy in diabetic hypertensive patients.  Telmisartan was having the better control on 24hr urinary albumin excretion.


Patient personalized treatment models can predict treatment response and assist in determining the optimal treatment option for individual patients. The tumor microenvironment mediates tumor development and prognosis. However, current tumor models such as patient‐derived tumor xenograft (PDX) and 2D culture models fail to preserve the patient‐derived tumor microenvironment. Herein, a technique for acoustic‐droplet‐printing‐of‐patient‐derived‐organoids (ADPDOs) is reported, which allows for high‐throughput, high‐viability, rapid, and uniform printing preparation of patient‐derived organoids. In particular, the ADPDOs are uniform in size and retain the parental tumor/fibroblast cell composition, mimicking a more realistic 3D environment of parent tissue in vitro, with histological features and protein expression closer to that of the tissue. Therefore, ADPDOs hold promise for application in personalized precision therapy for different patients. The authors test the clinical drug treatment response of different patients in a fast and convenient way to predict the therapeutic effect of various patients. Thus, this technique has great potential for predicting treatment response to personalized cancer therapy and constructing complex 3D tissue models.


Hybrid organic electro-optic (OEO) modulators consist of aligned OEO chromophores confined in a metal or semiconductor slot waveguide, enabling optical fields to be tightly confined within the OEO material. The combination of tight confinement with the high electro-optic (EO) performance of state-of-the art OEO materials enables extraordinary EO modulation performance in silicon-organic hybrid (SOH) and plasmonic-organic hybrid (POH) device architectures. Recent records in POH devices include bandwidths < 500 GHz and energy efficiency < 100 aJ/bit. To enable commercial applications of these materials and devices, however, the materials integration processes must be finely tuned to afford excellent EO activity and long-term stability under demanding conditions, both during manufacture and operation. The conceptually simple design of POH devices affords a useful platform for process optimization, while the intense optical confinement provides an ideal environment to examine the photochemical stability of OEO materials in hybrid modulators. We have performed process optimization to obtain good EO performance with commercial and developmental OEO materials in POH devices, and examined the long-term operational and shelf storage stability of such devices under a variety of conditions relevant to Telecordia GR-468-CORE standards. We analyze the results of these studies and discuss their implications for commercial applications, including manufacturing, encapsulation requirements, and expected operational lifetimes.


Interferon plays an important role in the response of the entire organism to a viral infection. The level of interferon in serum is at present difficult to measure especially at low levels and transiently high levels so that interferon activity in virus infections has sometimes not been detected. Interferon measurements has thus been quite useless as a diagnosticum.In vitro the 2'5'oligoadenylate synthetase has been shown to increase dramatically in a large variety of cells in culture after interferon treatment. This focus attention upon the possibility of using 2'5'oligoadenylate synthetase as a marker of interferon presence and by this as a dianosticum of virus infection. In the present study 2'5'oligoadenylate synthetase has been measured in mononuclear cells from Herpes zoster patients (N 7) and after interferon treatment of broncogenic carcinoma patients (N 7). It is shown that 2'5'oligoadenylate synthetase activities were increased in Herpes zoster patients (range 5-10 units/106 cells (1 unit converts 1 nmol/min)) and in broncogenic carcinoma patients after interferon treatment (range 2.7-8.4 units/106 cells) in comparison with normals (N 20) (range 2.5-0.4 units/106 cells).

In the early days of industrial revolution the waste water generated was simply passed to water bodies like rivers, wells, etc. which was fine for that time as the amount of wastewater generated was very less. The process of dilution was the principle and water purification used to take place by surrounding environment of water called as self-purification of streams. But as soon as the more and more industries were established it was seen that the self-purification process fails to purify water because the quantity of wastewater flown in water bodies was much more than its capacity to purify it. Hence there was a need of effluent treatment plants. Textile industry creates a lot of wastewater having very high amount of color. The color present in water reduces its acceptability aesthetically. Also the color present in water hampers the process of photosynthesis for the plants and other photosynthetic species if directly discharged in water bodies. The textile wastewater also has very high pH, COD, BOD

The following case study reports the successful treatment of a heavy smoker (age = 33) in a one hour session using a multimodal approach. Before treatment, the therapist made a verbal contract with the client who confirmed that he was ready to give up smoking and that the proposed approach would be a complete abstinence programme. Having agreed to this, the patient then agreed to throw out all smoking paraphernalia. In the first session, having identified times of the day when smoking occurred, the therapist gave conditioning trials (Cautela, 1967, 1968; Kraft & Kraft, 2005) for each time of the day, pairing the thought of smoking with an aversion. The therapist utilized the client's personal motivations to encourage smoking cessation, used split screen imagery (Taylor, 1985), ego strengthening, and gave suggestions that any cravings would be significantly reduced or absent. Further, he was encouraged to enjoy the sensations of being a non smoker during hypnosis. The client, who had not smoked that day, remained smoke free and maintained this abstinence at one year follow-up. This case study demonstrates that hypnosis is a cost effective form of treatment (Barber, 2001) for smoking cessation.


enced both destabilizing factors as well as success in promotion of regional cooperation. The destabilizing factors consisted of the tsunami damage caused by the Indian Ocean earthquake and the terrorist bombings which occurred in Bali in October. On the other hand, regional cooperation was promoted by the Peace Agreement of Aceh, the convening of the Myanmar National Convention, and the holding of the East Asia Summit. On the economic front, ASEAN member countries, while gradually recovering their growth trends, are actualizing growth by using as leverage the free trade agreements (FTAs) inside and outside the region and are strengthening cooperative relationships in preparation for the formation of the ASEAN Community. To promote formation of the ASEAN Community, a summit meeting on Mekong River Basin development as a measure to correct the noted economic gaps in the region was held in Kunming in Yunnan Province, China, in July. The summit adopted the "Kunming Declaration," which aims to achieve both the strengthening of the industrial base, including installation of transportation and communications networks, and protection of the ecosystem of the Mekong River. Overall, it may be said that the expansion of regional cooperation through the holding of the East Asia Summit will steadily contribute to the strengthening of the identities of the member countries. For example, according to the public opinion survey of six ASEAN countries released in December (Straits Times, December 5, 2005), in response to the question "Do the people of the ASEAN member countries think of themselves as being part of a single group?" 60.3 percent answered "yes" and 35.5 ASEAN: Significance of and Issues at the First East Asia Summit


The interest for the development of micro air vehicles (MAVs ) with the capability of desirable flight characteristics has been steadily increasing over the past decade. The ability of a MAV to successfully fly has implications for improving military and commercial operations, possibly space exploration as well. An understanding of the forces generated by MAVs is an important step in achieving desirable flight. The objective of this research project is to measure and analyze the forces generated by a flapping wing MAV. It was achieved by using an ATI Nano17 Titanium Force/Torque transducer by measuring and recording the forces generated by the flapper in the x, y, and z directions. The recorded forces were processed using a low pass filter created in MATLAB and the average forces in the z and x direction were plotted for specific applied voltages. Additionally, a Fast Fourier Transform was also executed in MATLAB to determine the flapping frequency of the MAV; it was plotted against the maximum and average forces. The results of the data analysis concluded that lift increases with flapping frequency but drops off at higher frequencies. The flapper can lift a weight of approximately 14 grams at a flapping frequency of approximately 22 Hertz.


A model incorporating the direct and indirect effects of parental monitoring on adolescent alcohol use was evaluated by applying structural equation modeling (SEM) techniques to data on 4,765 tenth-graders in the 2001 Monitoring the Future Study. Analyses indicated good fit of hypothesized measurement and structural models. Analyses supported both direct and indirect effects of parental monitoring on adolescent alcohol use. Peer influence, perceived alcohol norms, and conventional bonds mediated the relationship between parental monitoring and adolescent alcohol use. Results suggest parental involvement and proactive parenting skills as critical components of prevention and intervention programs that target adolescent alcohol use.


This study investigates whether the composition of bank debt affects payout policy. We identify that information-sensitive depositors (institutional investors) are targets of dividend signaling by banks. We use a unique database of Brazilian banks, for which we are able to identify several types of debtholders, namely institutional investors, nonfinancial firms and individuals, which are potential targets of dividend signaling. We also exploit the features of the Brazilian banking system, such as the existence of several closely held banks, owned and managed by a small group of people, for which shareholder-targeted signaling is implausible, and find that banks that rely more on institutional depositors for funding pay larger dividends, controlling for other features. During the financial crisis, this behavior was even more pronounced. This relationship reinforces the role of dividends as a costly and credible signal on the quality of bank assets. We also find that payout is negatively related to the banks' cost of funding (interest rates paid on certificates of deposits), that dividends have a positive relationship with size and past profitability and that closely held banks pay more dividends than publicly traded banks, which is also in line with the signaling purpose of dividends. Finally, we find a negative relationship between dividends and the capital adequacy ratio, which indicates that regulatory pressure may induce banks to pay less dividends, and that that payout is negatively related to the growth of the loan portfolio, consistent with the idea of banks retaining earnings to increase equity and consequently their lending capacity.

In 1987 it was decided that Drax would be the first UK power station to be fitted with flue-gas desulphurisation equipment. Drax is the largest UK power station (4000 MW) and the largest coal-fired station in Western Europe. Work has now started on the FGD installation which, when completed in 1996, will be the largest in the world. The author discusses the reasons for choosing Drax and the limestone/gypsum FGD process. The installation of the system, the changes in the electrical system and the control and instrumentation are discussed. The civil work and project information are also discussed.

A 37-year-old man with medical history of human immunodeficiency virus infection presented with weight loss, upper abdominal pain, and vomiting. Physical examination revealed painful, erythematous to violaceous, cutaneous nodules of the face, legs and feet, associated with a similar mucosal purple lesion of the tongue, the palate and the gingiva. The patient confessed a poor compliance with his antiviral therapy for several months. Laboratory studies showed severe immunosuppression (CD4 T-cell: 84/mm). Upper gastrointestinal endoscopy revealed multiple nodular, red, and infiltrating lesions of the esophagus, the stomach, and the duodenum (Figs 1 and 2). Digestive biopsies revealed characteristic spindle cells and irregular vascular channels filled with blood cells in contact with Brunner's glands (Fig. 3). Tumor cells were highly reactive to the human herpesvirus-8 marker (Fig. 4). Restoration of the immune system with anti-retroviral therapy (CD4 T-cell: 289/mm) associated with chemotherapy with pegylated liposomal doxorubicin reduced skin and mucosal Kaposi's lesions and improved digestive symptoms. Forty to fifty percent of patient with skin lesions have visceral involvement, especially to gastrointestinal tract (GI-KS). The upper digestive tract is the main site affected, in 60% to 90% of GI-KS. Despite the high frequency of GI-KS, the majority of patients are asymptomatic. With disease progression, non-specific digestive symptoms may appear as abdominal pain, nausea, vomiting, digestive bleeding, or iron deficiency anemia that require endoscopic exploration. Treatment of AIDS-associated GI-KS is based on highly active antiretroviral therapy, which inhibits KS cell growth, invasion, and angiogenesis; and systemic chemotherapy with liposomal doxorubicin. Relapses occur in 13% at 4 years, mainly during the first year.


Increasing research is filling the gaps existing between hermeneutics and translation, bringing about a coherent and unified whole. As a contribution, my co-authorized, developmental paper which addressed the challenging complex of hermeneutics, poetry, and translation, was prepared under conditions that did not allow for in-depth preparation, re-reading, and revision. Yet, as a promptly prepared project, it had some merits that are important for expanding the realm of hermeneutics and translation. The purpose of the present essay is to provide a relatively revised version and summary of the paper for interested readers. The original study seeks to move beyond the mainstream linguistic approaches to translation, by highlighting the historical convergence between translation and hermeneutics. However, as the retrospect shows, this convergence has suffered from methodological flaws, because hermeneutic conceptions have mainly remained abstract, at least to the readers who appreciate pre-fabricated tools for translation analysis. To overcome this problem, the paper proposes a complexity-regulated model that helps more objectively process poetry translation. The important point is that the domestication-foreignization parcel of the model has become outdated and must be re-framed in the light of new research.


The equipment support of the integrated joint operation is one of the current focus issues. Focus on the integrated joint operation and compared with the traditional pattern of battle, the paper mainly analyses the new characteristics and requirements brought by the integrated joint operation. The paper proposes the conceptive principle of the equipment command system of the integrated joint operation and discusses the integrated joint operation, the longitudinal hierarchy and the transverse institution setup in the integrated joint operation.


In object-oriented business support applications, separating business rules from core application functionality is crucial. Essential to business rules are their connectors to the core application, which existing approaches fail to support explicitly. Our paper presents requirements for encapsulating business rule connectors and shows that Aspect-Oriented Programming is necessary to fulfil them. All is illustrated with a small ecommerce example in Java™ and AspectJ.


Food desert can be found not only in rural area but also in city center. This study analyzed how food deserts are created; and what kind of countermeasures are effective, from a case study conducted in the provincial city center of Matsumoto. Five major avenues and the use of all buildings were surveyed and analyzed. As a result, it is found that food desert occurred due to changes in living environment. Also, the study showed small fresh food shops, which are the remnants of former environment, were effective in supporting those with low accessibility in the present environment.


Since Russia has reemerged as a global power, its foreign policies have come under close scrutiny. In Russia and theWest from Alexander to Putin, Andrei P. Tsygankov identifies honor as the key concept by which Russia's international relations are determined. He argues that Russia's interests in acquiring power, security, and welfare are filtered through this cultural belief and that different conceptions of honor provide an organizing framework that produces policies of cooperation, defensiveness, and assertiveness in relation to the West. Using ten case studies spanning a period from the early nineteenth century to the present day – including the Holy Alliance, the Triple Entente, and the Russia–Georgia war – Tsygankov's theory suggests that when Russia perceives its sense of honor to be recognized, it cooperates with the Western nations; without such a recognition it pursues independent policies either defensively or assertively.

This paper represents the first part of an effort to codify the knowledge required for manipulation tasks in a small-batch manufacturing cell. The motivation for this work is to pave the way for robots that can independently determine how to grasp and manipulate parts in a limited environment and to facilitate the design of advanced, but cost-effective manufacturing hands. We begin with an examination of grasps used by humans working with tools and metal parts. The grips are compared in terms of power, contact area, friction, damping and tactile sensitivity. The comparison leads to a grip taxonomy in which grasps are mapped against task-related quantities (such as power) and object-related quantities (such as slenderness). The examinations of the task requirements and grasps suggest a number of general principles for the design and control of manufacturing hands.


A Strategic Petroleum Reserve brine disposal site is located 11.4 km off the southwest coast of Louisiana. A grid of stations centered at the brine diffuser was monitored monthly for biological attributes during a 12 month period. Temporal and spatial distributions in species abundances and diversity were measured for the following: 1) macrobenthic invertebrates, 2) fishes and nektonic macrocrustaceans, 3) phytoplankton, and 4) zooplankton. These assemblages were studied relative to physical and chemical variations occurring in the study area. The marine fauna and flora of the diffuser area are characteristic of coastal assemblages of the northwestern Gulf coast. Population fluctuations were attributed to seasonal and hypoxic conditions. The macrobenthic community was dominated by polychaetes and phoronids; the nekters were typical of the white shrimp community; the phytoplankton community was dominated by estuarine and neritic species; and the zooplankton community was dominated by copepods with Penaeus spp. and Brevoortia spp. common in the area.


Hyperbranched polyacrylate copolymers were synthesized by self\|condensing vinyl copolymerization (SCVCP) of 2\|[(2\|bromopropionyl)oxy]ethyl acrylate(BPEA) and methyl acrylate(MA) in the presence of a tetrafunctional initiator(THABI).The structures of the polymers obtained were characterized by 1H\|NMR and SEC/refractive index(RI)/right anagle laser light scattering(RALLS)/differential viscometer(DV).Molecular weight(MW),molecular weight distribution(MWD) and degree of branching(DB) were influenced by conversion and initial feed molar ratio of BPEA,MA and THABI.The addition of THABI can narrow the MWDs of the polymers obtained.The results are consistent with our simulation result.


Logic built-in self-test (LBIST), originally introduced for board, system, and in-field tests, is now being increasingly used with on-chip test compression. This hybrid approach allows LBIST to become a complementary solution for in-system test, where high quality, low power, low silicon area, and most importantly short test application time are key factors affecting ICs that are targeted for safety-critical and automotive systems. Test points are common in BIST-ready designs where they play a key role in reducing both test application time given a test coverage goal and the overall silicon overhead so that one can get a desired coverage with the minimal number of patterns. Unfortunately, these test points are typically dysfunctional when enabled in an ATPG-based test compression mode. Similarly, test points used to reduce ATPG-based test pattern counts cannot guarantee desired random testability. Incompatibility of both types of test points has motivated research presented in this paper. We present a novel hybrid test point technology designed to both reduce deterministic pattern counts and improve fault detection likelihood by means of the same minimal set of test points. Experimental results obtained for large industrial designs illustrate feasibility of the proposed hybrid test points and are reported herein.


The effect of dosing compound microorganism preparation and enzyme preparation on pollutant removal from river water in a constructed wetland was studied.It was showed that compound microorganism and enzyme both preparations could inprove microorganism quality and enzyme activities,and raise pollutant removal rate;an obvious correlation existed between ammonia nitrogen removal rate and nitrified bacteria number;the correlation of the group with dosing bacteria was markedly higher than that of the control group,indicating that the dosage of both preparation of compound microorganism and enzyme strengthened the ammonia nitrogen conversion in constructed reed wetland.


This is the introduction to the Special Issue published in June 2016 in (7) European Journal of Risk Regulation (2), pp. 295-296. The Special Issue was edited by Thomas Burri and Isabelle Wildhaber and includes five articles on "The Man and the Machine: When Systems Take Decisions Autonomously", written by the following authors: Shawn Bayern, Madeleine de Cock Buning, Ugo Pagallo/Massimo Durante, Melinda Florina Lohmann, and Thomas Burri.


The category of periphery – although fundamental for the study of political space – seems to be troublesome, not to say suspicious. Due to its ambiguity and vagueness, it often serves as a handy tool for conducting sharp ideological disputes. The controversy around this category arises from the fact that no one wants to live in marginal territories and so this awareness is often supressed and denied. Peripherality – like an insurmountable fate – is associated with backwardness, stagnation and, above all, a lack of autonomous concepts for the development of a given entity. Margins are usually regions that do not participate in mainstream modernisation processes due to their specifi c history and identity, which are not easy to reconcile with functioning in a supranational community. The purpose of this work is to analyse the functioning of periphery areas in global structures, with particular emphasis on integrative groups such as the European Union (EU). The hypothesis of this analysis is that the crisis of the liberal architecture of the globe may affect the tendency of the margins to replace real convergence


The phenomena of minor disruptions during current flat phase have been observed in the HL-1 device for five years. When these phenomena appear the safety factors are 2.5≤qa≤4.5,and densities are 1 × 1013cm-3≤ n≤3×1013cm-3 or n≥4× 10I3cm-3. Periodic relaxation ocsillations of voltage and soft-X-rays are observed during minor disruptions. In the present paper, we carefully analyse their character and development conditions.


For a catchment in the north western slopes of N.S.W. which is affected by soil salinisation, a mathematical model has been developed to investigate economic aspects of management strategies. A model farm represents the cropping enterprises on the black-soil floodplains. The objective function of the model takes a medium-term economic perspective by optimising the cumulative net present value of available household income over five years. Located in the discharge zone of the catchment, the question arises whether there are ways for the model farm to control salinisation in a financially viable manner. This paper investigates the impact of two biophysical parameters on preferred salinity management strategies and financial viability of the model farm. They are the volume of upward leakage from the upper aquifer and the encroachment rate of salinity. The value of these parameters are shown to be decisive for the advance of salinisation, for preferred salinity management and farming strategies, and for the financial viability of the farming enterprise. If independent rise of waterlevel is low or salinity encroachment is slow, then management options range from adoption of opportunity cropping and short-fallow rotations, to introduction of lucerne, and to preventative tree planting. There is the prospect that salinisation can be contained and financial viability of farming be sustained. If the parameter values take the opposite extremes, then there is no financially viable salinity management strategy available. It has to be emphasised that it is critical for the quantitative economic analysis of soil salinisation that the values of these crucial biophysical parameters are established for different areas of the catchment through hydrogeological research.


Abstract In 2008, the world underwent one of its worst economic and financial crises, whose consequences are still visible in some countries. This paper aims to analyse the impact of the crisis within the long-term care systems of Germany, England, Sweden and Spain from a comparative perspective. The time period analysed spans from the outset of the crisis in 2008, up to 2017. This article starts off from the thesis of the divergent impact of the economic crisis in these countries and the convergence between the impact of the crisis and long-term care contractions in the most afflicted countries. The outcome highlights the power of economic and financial pressures in order to explain the contractions within the care policies. Equally, it emphasizes the contradictions between the formal development level of the care systems and their practical institutional implementation in the field.


. Ancient solutions of the Ricci flow arise naturally as models for singularity formation. There has been significant progress towards the classification of such solutions under natural geometric assumptions. Nonnegatively curved solutions in dimensions 2 and 3, and uniformly PIC solutions in higher dimensions are now well understood. We consider ancient solutions of arbitrary dimension which are complete and have Type I curvature growth. We show that a κ -noncollapsed Type I ancient solution which is noncompact and has nonnegative sectional curvature necessarily splits at least one Euclidean factor. It follows that a κ -noncollapsed Type I ancient solution which is weakly PIC2 is a locally symmetric space.


This paper presents a new method to draw particles in the particle filter. The standard bootstrap filter draw particles randomly from the prior density which does not use the latest information of the observation. Some improvements consist in using extended Kalman filter or unscented Kalman filter to produce the importance distribution in order to move the particles from the domain of low likelihood to the domain of high likelihood by using the latest information of the observation. These methods work well when the state noise is small. We propose a modified bootstrap filter which uses a new method to draw the particles in the scenario of a big state noise. We show through numerical examples that it outperforms the bootstrap filter with the same computational complexity

The adsorption isotherms of Sodium Dodecyl Sulfonate(SDS) onto wool fiber surface which experienced clean processing from an acid aqueous solution(pH3.0~3.5) by conductance method at 366K(93℃) were studied,so did the isotherms of wool adsorbing SDS from different aqueous solutions which containing various auxiliaries(containing glycol/benzalcohol and zinc sulfate).Some results can be found that all the adsorbed amounts of SDS show a descending trend at different degrees after adding the auxiliaries.The increasing solubility of the agent indicates the affinity of surfactant with water becoming stronger,and the trend of surfactant fleeing away water and adsorbed onto the wool is relatively decrease,which made the adsorbed amounts of SDS reduce.The surface micelle aggregation number and the standard Gibbs free energy for surface micellization of SDS adsorbed onto the wool/solution interface in the actions of different auxiliaries were estimated by the general adsorption isotherm formula,and the values of them is generally coinciding with the experiment results.The adsorption isotherms of disperse dye adsorbed onto the wool under the conditions of with and no auxiliaries("DL" or "FL") were also studied.The adsorption and dyeing mechanism was also explored.

One of the new active safety systems of the automobile is a system for stabilizing the vertical reactions of the wheels when moving along a periodic profile. The effectiveness of this system largely depends on the success of measuring the values of the vertical reactions of the wheels of the vehicle in motion. The possibility of solving this problem is considered in the article. As a first method for determining the radial reaction in a tire, the method for estimating the radial force from the change in internal pressure in it is considered. Theoretical analysis of this problem based on solving the simplest models, as well as more advanced models using the finite element method, is presented in the article. Another method for determining the radial force in the tire is to measure the radial deformation of the tire in the area of the contact spot. Two methods for determining radial deformation of a tire are considered in the article. One way is to use laser technology. The laser sensor is fixed to the rim of the vehicle wheel, which ensures a constant measurement of radial deformation at one point of the rotating tire. The use of such a device in the system of stabilizing the vertical reactions of the wheels of the automobile is almost impossible, because the frequency of the desired signal is too small. A more advanced version of the measuring device with a gyroscope ensures the continuity of the direction of the laser beam at one point - the center of the contact spot. This ensures the continuity of measuring the radial deformation of the tire during the movement. Another way is to use an annular chamber with a fluid supported on a ring like a ring fixed on the rim of a so-called "safe" wheel. Increasing the pressure in the chamber during radial deformation of the tire makes it possible to evaluate it. Another method of continuous measurement of radial force on the wheel is associated with performing measurements of the vertical acceleration of the center of the wheel and the total force transferred by the suspension to the wheel of the vehicle.


This article investigates the problem of how to control nonlinear systems with delays in the state by memoryless linear feedback. The notions of semiglobal asymptotic stabilization and sublevel sets are introduced in the context of time-delay systems. With the aid of Razumikhin theorem, we develop a semiglobal design method for the construction of Lyapunov functions, associated sublevel sets, and delay-free linear state feedback laws, step-by-step, achieving semiglobal asymptotic stabilization for time-delay nonlinear systems in a lower triangular form. In contrast to the global stabilization of nonlinear systems with delays in the state, which is usually achieved by dynamic state feedback (Lin and Zhang, 2020), the significance of this work is to point out that a tradeoff of the control objectives, e.g., semiglobal versus global stabilization, makes it possible to control a class of time-delay nonlinear systems by static linear feedback. Extensions to nonlinear systems with globally asymptotically locally expoentially stable (GALES)-like inverse dynamics are also included in this article.


The importance of fluoren-9-one (1), found in many biologically active products, 1,2 has been emphasized in organic chemistry. It consists of essential structural backbone of various pharmaceuticals. Also number of natural products have been found containing fluoren-9-ones showing a range of biological acitivities; e.g. dengibsin, dengobsinin, dendroflorin and kinobscurinone. Utility of fluorenone derivatives as photosensitizers in organic photoconductor devices and their electrical and optical properties are also important. 3


Bulimia nervosa is an eating disorder characterized by episodes of binge eating and various attempts to counteract the effect of the ingested calories. Relatively little is known about the metabolic adaptation to this nutritional chaos. The baseline metabolic state of 12 bulimic women was compared with 9 healthy matched controls; evidence of decreased insulin secretion in terms of low plasma c-peptide levels in bulimics is reported. This is discussed in the context of normal plasma insulin levels as a reflection of both abnormality and adaptation


Abstract This paper analyzes case studies in the context of industrial business networks, and in particular from the IMP (Industrial Marketing and Purchasing Group) perspective. Two features have been prominent in this research tradition: collaboration in international research teams and interest in business between international customers and their suppliers. Still, researchers seldom discuss the challenges with the international aspects of the research team (as the subject of study) or of the business relations (as the object of study). This paper shows the complications of analyzing international business relations, namely, relations that cross national boundaries, and investigates how an international research team can tackle the challenges of international business network studies. The key contributions are, firstly, to indicate the lack of attention on the methodological requirements and opportunities that the international features create for the analysis of business networks and, secondly, to investigate how collaboration in an international research team may advance the analysis of both international industrial marketing relations and broader business networks.

The voltage source phase-offset control of dual-three-point inverter has been analyzed by using method of power electronics control of SVG, the basie synchronous control method of SVG is also proposed according to the relationship of the phase-offset between the equal voltage source of inverter and power system, and input reactive power, that is so called phase-offset control. In this paper, the various electric curves are given at different circumstances for dual-three-point inverter.


The intensities of the infrared bands corresponding to symmetric ring breathing and symmetric methyl stretching modes have been measured for charge‐transfer complexes of iodine in benzene, toluene, the xylenes, mesitylene and 1,2,4 trimethylbenzene, durene, penta‐, and hexamethylbenzene. The ring breathing mode intensity is found to decrease and the methyl stretching mode intensity to increase with methyl substitution. These results are interpreted in terms of a previously proposed ``electron vibration'' infrared absorption mechanism [E. E. Ferguson and F. A. Matsen, J. Chem. Phys. 29, 105 (1958); J. Am. Chem. Soc. 82, 3268 (1960)] extended to include π‐electron interaction with methyl group electrons.

Effective lubrication systems are crucial to the successful application of ceramic materials in many advanced technologies. A review is given here of the tribochemistry of ceramic lubrication, including the effects of water, water-based lubricants, hydrocarbons, additives and solid lubricants, on the friction and wear properties of ceramics, the tribochemical mechanisms of ceramics with lubricants and the wear mechanisms of ceramics. Finally, some suggestions about further study of ceramic lubrication are offered.


Comparative effectiveness is the side-by-side comparison of medical options, such as treatment strategies, with respect to their expected benefits and harms. It is easiest to grasp by visualizing a table (Table 1). In this example table, the columns are treatment strategies (treatment options, including no treatment). The rows are the good (benefits) and bad (harms) outcomes that may occur as a result of the treatment choice. Probabilities for each combination of treatment and harm belong in the cells of the table. This table makes it easy to compare medical choices because the tradeoffs are explicitly presented. For example, drug A may have an increased risk of harm 1 but a decreased risk of harm 2 for a particular patient. The decision maker can appreciate exactly what is at stake when the choice is made. The perspective of comparative effectiveness is that of the individual patient confronting a specific condition; this perspective assumes that patients making better decisions benefits society. The probabilities in the cells of Table 1 must be tailored to the individual patient needing the decision. One-size-fits-all probabilities are not going to be very helpful or relevant. The patient needs to know what risks of harms or chances for benefits he is trading off with the choice for himself. For this reason, the table is best constructed with computer software because the probabilities need to change with each patient under consideration. More specifically, the probabilities most likely come from equations or algorithms that consider the specific features of the patient so that the probabilities are tailored to his situation. Moreover, these probabilities may need to be tailored to his provider (e.g., his surgeon or surgeon's experience) or his hospital (or hospital volume). The tailoring process is complicated but must reflect an individual's chances, taking into consideration everything possible regarding the type of care he is going to receive. Thus, considerable work must go into the designing of the equations that relate the probabilities in the table to the characteristics of the situation. When the cells of Table 1 contain probabilities, which is typically the case, uncertainty estimates (e.g., 95% confidence intervals) are not relevant to the individual patient and may thus generally be omitted. The equations that relate the patient's characteristics to the expected outcomes need to be constructed carefully. In particular, they should be designed with accuracy in mind. An attractive feature of the comparative effectiveness table is that it sheds light on the role of particular patient features in the treatment comparison. For example, disparities or setting of patient care may affect the outcomes for one or more treatments. One of the features that might go into the tailoring could be race, for example. However, features such as disparities or location only need to be factored into the tailoring if they improve the predictive accuracy of the statistical model, which is easily testable. This attention to predictive accuracy helps shelter the analysis from political or funding pressures because incremental predictive accuracy is an objective goal that is difficult to manipulate with either money or politics. Demonstration of improved predictive accuracy guards against conflict of interest and allows for broader funding arrangements than would ordinarily be allowed in medical research.

Background: Pediatric Index of Mortality 2 (PIM2) is a useful scoring system for the prediction of prognosis, and Oncological Pediatric Risk of Mortality (O-PRISM) for ICU support in children with HSCT. We investigated prognostic prediction and risk factors for survival through early detection of admission to ICU after HSCT. Methods: We reviewed retrospectively medical records of children cared for in ICU after HSCT between 2004 and 2010. Patients who died within 2 hours after admittance to ICU were excluded. We analyzed the worst parameters in ICU by a t-test, Cox-regression, multiple logistic regression and a receiver operating characteristics curve (ROC). Results: 54 children, with fifty-five disease events, were admitted to ICU after HSCT. Sixteen children were diagnosed with high-risk disease status and 8 with non-malignant diseases. Stem cells were sourced from 14 matched siblings, 22 unrelated donors and 19 cord bloods. The median duration in ICU was 8.5 days (0.5−110). The reasons for admission to ICU were 32 pulmonary, 14 neurologic, and 9 hemodynamic events. Six patients (11.1%) survived after intensive care. The factor indicating discharge with survival was mental status (p = 0.04), although other factors included FiO2, prothrombin time, potassium, and pupil reflex in univariate analysis. In multiple logistic regression, there were significant factors of PaCO2 (p = 0.028), O-PRISM (p = 0.039), and PIM2 (p = 0.004) for prognosis. For prediction of prognosis, O-PRISM (p = 0.019) was superior to PIM2 (p = 0.435) in intensive care children after HSCT. Conclusions: O-PRISM might be a predictable scoring system for children with ICU support, and the Glasgow coma scale and PaCO 2 were more reliable prognostic factors in the post-HSCT period.


Background:  Exhaled breath condensate (EBC) is a noninvasive method to obtain samples from fluids lining the respiratory surfaces. Even though various methods and devices are now available, the relative efficiency of these methods for recovering airway mediators and characterizing EBC has not been established.


Potatoes were planted on 5 May in Sunderland, MA. However, during the first week of Jun ca. 9 inches of rain fell in a 2-day period, destroying the crop. Superior' potatoes were replanted on 28 Jun. The soil type was a fine sandy loam with a pH of ca. 5.6. Treatments were replicated 3 times in a completely randomized design. Each plot consisted of two 30-ft rows, 3 ft apart. A fallow area of 6 ft separated each plot. Treatments were applied with a 3-gal stainless steel CO2-pressurized sprayer at 40-psi with a delivery rate of 60 gal per acre. Applications were made on 31 Jul, 7, 14 and 20 Aug. Furadan 15G 3.0 and Temilc 15G 2.0 were applied at ground break on 19 Jul. Defoliation was evaluated 16 Aug, rating plots from 1 (0-15% defoliation) to 5 (85-100%).


Behçet's disease (BD) is a recurrent systemic autoinflammatory disorder of unknown etiology (2). It was first described in 1937 by the Turkish dermatologist Hulusi Behçet, featuring a triad of recurrent oral aphtae, genital ulcerations, and uveitis (1). Currently, criteria established in 1990 are being used for the diagnosis (3). However, other than those cited in these criteria, many other organ systems may be involved in BD such as the vascular system, mainly the veins and pulmonary arteries, gastrointestinal system, joints, and the nervous system (4). Males are more commonly and more severely affected, and the usual onset is around the third decade. BD is more prevalent in Japan, mid-Asia, Middle East, and Mediterranean basin, therefore called "the Silk Road disease" by some authors.


Abstract Buzzard Point in Washington, DC, is a neighborhood facing the brunt of urban environmental injustice. Through pollution from multiple sources and a lack of environmental amenities, residents have been exploited and drowned out to make way for further development. This project used Photovoice, a community-engaged research method, to give residents a voice in identifying the health hazards in their communities. The method highlighted in this article was modified for a classroom project, but still yielded important themes of abandonment and hopelessness. These findings mirror other works with Photovoice, which have been used in both urban and rural settings to identify cumulative health hazards and harmful elements of the built environment. This Photovoice project serves as a first step in empowering residents, bringing attention to lawmakers of their plight, and initiating a dialogue on the reforms the city can adopt to improve physical and environmental health in the community.


The partial dislocation of the talus on the tarsal mechanism has been recognized as the root cause of multiple foot and lower extremity pathologies. Many conservative and surgical treatments have been utilized to treat this pathologic condition. The purpose of this multi-centered prospective study was to compare weight-bearing radiographic correction achieved in patients with recurrent talotarsal joint dislocation (RTTJD) treated with foot orthoses to that achieved in the same patients through an extra-osseous talotarsal stabilization (EOTTS) procedure. Radiographic data was obtained with no intervention (barefoot), on the orthosis and post-EOTTS from 19 patients (30 feet). Change to the pathologic angles measured for the talar 2nd metatarsal (T2M) on the anteroposterior (AP) view and talar declination (TD) angle on the lateral view were analyzed. The reduction in the angles following the use of orthoses was insignificant in both the transverse and sagittal planes. Following the EOTTS procedure, there was a significant change towards accepted normal weight-bearing radiographic angles in the transverse and sagittal planes. In the transverse plane, the EOTTS procedure resulted in an average 58.92% reduction and in the sagittal plane, a 28.32% reduction compared to pre-operative barefoot measurements. By comparison, the change from barefoot measurements to orthosis was 3.20% and 2.20% respectively. The EOTTS procedure did not result in an increase in pathologic angles or cause any angles that were within the normal range pre-operatively to become pathologic. These results support the hypothesis that the EOTTS procedure is more effective in stabilizing RTTJD as compared to orthoses.


Fires in the oil tanks are caused by the thermo-oxidation of ferrous sulfide which is corrosive products of oil tanks containing sulfur. The investigation of the effects of flow rate of air, the existence of oil, monocrystal sulfur and particle sizes of ferrous sulfide on spontaneous combustibility of FeS was carried out. The experimental results show that the oxidation reaction rate of FeS at the 2.6 mL/min flow rate of air is faster than that of FeS at the 1.4 mL/min. So the oxidation reaction rate is accelerated when the flow rate of air is increased. Thus air entering into the oil tanks is the serious threat to the safe running of the oil tanks. To be safe the inert gas should replace the air to enter oil tanks in the process of discharge. The oxidation reaction is restrained when the surface of ferrous sulfide is covered by crude oil, since the existing oil layers prevent the reaction between ferrous sulfide and the oxygen in the air. the oxidation reaction rate of FeS with particle sizes between 20 and 40 mesh is faster than that of FeS with particle sizes between 80 and 100 mesh. So the finer the particle size of ferrous sulfide is, the greater the risk of self-ignition of oil tanks could become greater; the oxidation rate is accelerated after monocrystal sulfur is melted.


This research was conducted on WhatsApp and Facebook social media users, the aim of observing the behavior of the users of both social media, related to the issue of the pandemic Covid-19, which is sweeping the world. Indonesia is a country in the risk category, after a number of people with positive Covid-19 found. During the period March 10-17, 2020, conversations of members of the WhatsApp Group Alumni Association of the Faculty of Social and Political Sciences, Hasanuddin University, whose members tended to be heterogeneous, from various professional fields, were also spread throughout Indonesia, with more than 200 members and Lecturer groups FISIP University of Eastern Indonesia (UIT) Makassar, whose members tend to be homogeneous, and only resides in Makassar City. The Facebook group that was observed was a journalist group. It was revealed that Facebook and WhatsApp users were actively disseminating Covid-19 information in the form of religious propaganda, medical information, political responses, humorous humor. On both social media accounts, user behavior appears to be active, continuously informing the Cofid- 19 phenomenon, with various versions, including news links, opinions, analysis of both amateur and expert experts, criticism of the government, to memes and images that sometimes are photos of officials country. Research uses qualitative methods to explore and understand the meaning of messages. The approach and method of analysis used in this study are, content analysis method using quantitative data and qualitative data simultaneously.


The mammographic image quality criteria published by European Commission were implemented in three mammography equipments of a same radiology department in a hospital of Sao Paulo city. Among the mammography equipments, two use the screen-film system and one of them uses the indirect digital system. During the data collection, it was noted the need to conduct a study about image rejection in each mammography equipment. Therefore, this study was realized and, after that, the results in each mammography equipment of image rejection and image percentage that present each quality criterion it were compared. At the same time of this studies, it was realized other study about surface entrance dose and average glandular dose. These doses it was estimated based on different methods published by different groups of researcher, for all combinations anodefilter available in the equipment. To estimate the surface entrance dose following the methodology published in ANVISA' guide and the average glandular dose following the Wu' methodology, it was developed a phantom, in different thicknesses of acrylic, to simulate a breast. Finally, the image quality it was associated with the dose received by patient. The digital equipment shows better results in the evaluation of quality criteria, lower rate of image rejection and lower values of average glandular dose and surface entrance dose in all methods studied. But it is not sufficient, because is not adequate for patients with great breast.


Phenotypic markers of chromosomes are useful for determining chromosome behavior in cytogenetic studies. Transmission of an alien, telocentric addition from Agropyron tricophorum (Link) Richt. that confers purple aleurone pigment and blue seed color was evaluated in common wheat (Triticum aestivum L.). Twenty-five of 2570 seeds from bagged heads of eight ditelocentric-addition sister plants were almost white rather than blue. Seven of these 25 seeds and 4 of 336 blue seeds segregated 41.4%:58.6% blue:white. Meiotic analyses showed that all plants grown from these 11 seeds were spontaneously produced monotelocentric additions. Transmission of the alien telocentric chromosome through the egg and the pollen was estimated to be 19.5 and 14.3%, respectively, based on BC1F1 seed color. About 28% of F2 and F3 seeds were blue; of these 7.4% were ditelocentric additions. The frequency of blue seed in F2 progeny from spontaneous monotelocentric additions (41.4%) was significantly greater than that of monotelocentri...

Catalase can accelerate the decomposition of hydrogen peroxide in the organism.To compare with the experimental method in the textbook,this method of quantitative test of catalase activity is simple and the experimental effect is obvious. It makes up for the lack of qualitative experiments and delves into the experimental material for mensurating catalase activity and the condition of affecting catalase activity.


We describe the type IIB supergravity background on AdS3⊗S3⊗T4 using the potentials of AdS3|4⊗S3⊗T4 and we use the supersolvable algebra associated to AdS3|4 to compute the κ gauge fixed type IIB string action. From the explicit form of the action we can clearly see how passing from pure NSNS backgrounds to pure RR backgrounds the WZW term disappears.


For many years, I have been recommending Reflex (published by Borland International) as a tool for analyzing financial and statistical data. My primary reason for this recommendation has been that Reflex allowed me to cross‐tabulate data. If you want to look at the year's financial data broken down, for example, by month‐by cost center‐by line item, you are essentially dictating that you want to do a crosstab. Reflex has a built‐in "view" that allows you to construct a two dimensional table that, with data limiting capabilities, yields a surprisingly diverse and multidimensional look at your data. In fact, I installed a financial reporting system in a library back in 1987 that was based on Reflex. In 1993 the library finally changed over to a commercial reporting system (costing thousands of dollars) that replaced Reflex. Yet, the old system provided a fairly flexible reporting and analysis system.


There is a wealth of literature on evaluation of which proximate determinant models and input and output models are pertinent to this paper. An examination is made of the value of impact evaluations for health care projects in developing countries and their acceptability to senior health planners and 14 field directors of major European bilateral aid agencies. The model used in this survey of perceptions of senior officials and field staff includes inputs process outputs outcomes and impact. Intermediate variables are curative exposure susceptibility constitution at birth and nutrition; risk factors are the last 4 intermediate variables which are interactive. Exposure variables lead to infections and malnutrition which leads to death or survival. Van Norrens proximate determinant model is difficult to apply to community health services and more appropriate for specific programs. Some of the problems with evaluation models are identified: 1) that program effectiveness must be determined before impact; 2) that low input per capita projects should be expected to yield substantial health impact; 3) that instant results are unlikely and time-lags for many public health oriented interventions are unknown; 4) that suitable control groups are needed for comparison; 5) that impact measures are not sensitive to inequalities in health risks or access to services; 6) that health interventions may be misspecified as improving mortality and measures of mortality are affected by competing risks. Interviews were conducted with key officials to determine which evaluation procedures were used and preferred and why and to assess awareness of conceptual and technical problems in evaluation. Clear definitions of input process output outcome and impact were effective in eliminating differences in the jargon of respondents. Most respondents favored impact evaluations and indicated that there was no policy to direct choices. There was no agreement about whether PHC projects should always be evaluated in terms of health impact. The advantages of impact evaluations were reported as demonstrable results and conceptualizations. Field directors were not as convinced of the utility of impact evaluations and saw the advantage as political rather than as benefiting aid recipients. It is likely that impact evaluations will continue in spite of policy leading science.


Bronchial asthma in childhood is often associated with a topic dermatitis, allergic rhini t is, recurrent respiratory infections, eosinophilia, or increased serum Ig E concentration. Impaired host defence mechanisms against infection or defective immunological responses might contribute to these clinical problems. Chemotaxis and chemiluminescence of the peripheral neutrophils and blastoid transformation of lymphocytes to phytohemagglutinin stimulation were examined in atopic type asthma patients aged 2 to 21 years. The chemotaxis of neutrophils was not distinctively decreased in the asthmatic children, as judged by an agarose plate method, and the rate did not correlate with the peripheral leukocyte counts, the amount of C-reactive protein, the serum IgE concentration, peripheral eosinophil counts, the frequency of asthma attack nor with the duration of hyposensitization treatment. However, a positive correlation with age was observed. Chemotactic difference and chemotactic index were greater in asthmatic patients than those in neutrophils of healthy adults. There was no indication of suppressed oxygen metabolism in neutrophils from asthma patients, as revealed by the chemiluminescence measurement. In addition to the fast chemiluminescence burst which might be caused solely by the neutrophil activity, there observed a slow but greater chemiluminescence burst (response) as the eosinophi1 counts increased in the peripheral blood. Blastoid transformation of lymphocyte was not markedly suppressed in the asthma patients. However, in some cases, the suppression was observed after hyposensitization therapy, suggesting a possible involvement of cellular immunity in hyposensitization.


To the editor:

The genetic determinants that govern the phenotype associated with chronic myelomonocytic leukemia (CMML) and myelodysplastic syndromes (MDS) are unknown. Many recurrent mutations occur in both diseases, suggesting that the presence or absence of a solitary mutation is insufficient


The study of the human as a controller of processes is becoming more important as industries become increasingly mechanized. This study attempts to model the human process controller when he is initiating or optimizing the process. A laboratory simulation of a two input variable and one output variable process is designed similar to that employed by Rigby (1972). Thirty-five (35) human subjects are run under several different conditions. Measures of human strategy along with system-state variables which humans might use to determine their strategy are developed and compared. On the basis of these data, a model is proposed of the human operator during the initial stages of controlling a process.


RepRap (Replicating Rapid Prototyper) is an open-source 3D printer which current revolution from rapid prototyping technology. The technology has become well-known to the public and starting to widely commercialize in the market. The low cost and flexibility of the open-source 3D printer become the alternative for making three-dimensional parts. The advantage of using this technology is that the user has a complete freedom of controlling the process parameters of the fabricate product. Despite of being a low-cost 3D machine, there is no extensive study of the performance on this technology. This paper investigates the impact on process parameters for tensile strength using polylactic acid (PLA) material. Parts were printed using newly developed open-source 3D printer with Repetier-Host software by manipulating three parameters which were layer thickness, shell thickness and printing speed. The printed parts were tested under tensile test machine and the analysis from ANOVA shows that the shell thickness contributes higher significant impact on tensile strength.
