On September 1, 2010, this journal published my story ''Leaving for College.'' Two years later it published the sequel ''Back from College.'' In 2014, another sequel was published, ''High School Reunion.'' In these stories a dying man and his grandson converse about life, death, and good times fishing together on the grandfather's pond in Virginia. In the following story, the grandson recalls the wisdom of his deceased grandfather. . It is 6:15 a.m. in New York City. Near a sidewalk in front of the Greek Orthodox Church I notice an old man sleeping under a Christmas tree. The lights from the tree flicker off his pale face and beard. A tattered sleeping bag covers the rest of his body. ''Christos Anesti,'' he mumbles, as I walk by him. ''He has truly risen,'' I respond, without thinking. Christos Anesti means ''Christ has risen,'' something Greek Orthodox Christians say to one another during Easter, not Christmas. Before walking into the church I hesitate a moment and look back at the man and ask, ''Would you like to come—'' He coughs loudly and turns his back to me. ''Would you like to come inside?'' I repeat. No answer. I take off my gloves and pull a few dollars from my wallet. I place the bills under the tree. I'm a few minutes late for Bible study. From the door to the church hall I can see the priest serving coffee and donuts to several men sitting at a long table. Behind them there is a theater stage with Christmas props—a manger scene, bales of hay, and a makeshift stable. I make my way to greet the priest. We shake hands and he pours me a cup of coffee. ''Welcome, John. Your hands are really cold! It's good to see you this morning.'' He takes his Bible and moves to the podium below the stage. I've been in this men's study for two years. There are 10 of us who regularly attend. It's not easy, but every Wednesday morning I get up at 5:30 a.m., shower, and grab a bagel at the bakery across the street from my apartment building. From the bakery I walk five blocks to the subway station, travel uptown, and then walk another three blocks to the church. We meet for an hour, and then I'm back on the subway to Wall Street where I trade equities. ''Greetings, faithful men,'' the priest says. ''Today's lesson is from the Old Testament book of Ecclesiastes. As you may know, 'ecclesiastes' is the Greek word for 'teacher.' In this rather pessimistic book, the teacher declares that all is vanity. Work, pleasure, money, and even wisdom—these things are meaningless in life, the teacher says. My question to you today, brothers: do you believe the teacher?'' My grandfather has been dead for seven years. He died during my first year of college. He was a literature and religion professor at State University in Virginia. We would fish together on the pond below his farm house, and talk for hours about life and growing old. Pops taught me to read and reread the Bible throughout my life. When skeptical students at the university asked him to defend his beliefs, he would direct them to Ecclesiastes:


A bounded-skew planar clock routing algorithm is presented in the paper, which consists of two steps: first, a planar clock router generates a non-delay-balanced clock tree; and then a buffer insertion technique is used to obtain a bounded-skew planar clock tree. The experiment results show that the algorithm is efficient.

Introduction: Subacute granulomatous thyroiditis or subacute thyroiditis (ST) is characterized by neck pain or neck tenderness and physical examination usually shows diffuse enlargement and tenderness of the thyroid gland. Its etiology often involves a viral infection and ST manifestations occur during the recovery phase of this infection. In this study, we conducted a retrospective data review of 24 patients diagnosed with ST who were followed at our clinic. Patients and Results: Twenty-four patients (18 females, 6 males) with a mean age (±SD) of 41±10 years (min-max: 33-71) were followed. There was no significant age difference between males and females. Laboratory findings were as follows: mean sT4 value 2.7±1.5 ng/dL, sT3 5.5±3.3 pg/ml, TSH 0.2 ±0.4 mlU/mL, erythrocyte sedimentation rate (ESR) 82±27 mm/h, C-reactive protein (CRP) 56.4±36.5 mg/L, average leukocyte count 8762±2496/ mm3, absolute neutrophil count 5940±2390/ mm3. One patient had elevated anti-thyroid peroxidase (Anti-TPO) and four patients had elevated anti-thyroglobulin (Anti-Tg) antibody levels. The mean time from the onset of an upper respiratory tract infection until ST diagnosis was 39±28 days (min-max: 7-90), the mean duration of follow-up was 200 ±125 days (min-max: 30-370) and the mean duration of clinical manifestations of ST was 130±38 days (min-max: 65-195). Following a ST episode, 19 patients were euthyroid and 3 patients were hypothyroid. The outcome was unknown in 2 patients. Conclusion: ST affects daily life performance adversely due to symptoms of severe neck pain and difficulty swallowing. As can be seen in the case of our patients, the diagnosis of ST is rather difficult unless it is actively sought and on average, it takes 39 days to reach a definite diagnosis. Thus, ST should be considered in the presence of unexplained neck pain with ESR and CRP elevations.


A75-year-old right-hand dominant woman attended the emergency department with both arms locked in the erect position. She had fallen off a ladder and had landed vertically down on both outstretched hands. Her past medical history was unremarkable. She had had no previous shoulder trauma. On examination, both humeral heads were palpable in the axillae, lying against the lateral chest walls. On neurological assessment of the extremity, paraesthesia in the regimental badge area with deltoid weakness was noted, affecting the left shoulder. Bilateral inferior shoulder dislocations, with no associated bony injuries, were confirmed on a chest X-ray (Figure 1). A closed manipulation was successfully performed under sedation in the emergency department (Figures 2 and 3).

The preliminary results of utilization of bottom ash from combustion of biomass for the produce of concrete has been presented. Currently, this waste are deposited in industrial waste landfills. The chemical composition of waste materials was determined using X-ray fluorescence (spectrometer ARL Advant 'XP). Concrete were made using CEM I 42.5 R (Cemex) and sand - gravel mix aggregate. The obtained concrete were subjected to microscopic examination (LEO Electron Microscopy Ltd.) and their compressive strength (PN-EN-196-1) and absorbability (PN-85/B-04500) were identified. The obtained results showed, the replacement of the natural aggregates by bottom ash from combustion of biomass reduce consumption of raw materials and will have a good influence on the environment.


Purpose – This paper aims to present a three‐dimensional computational fluid dynamics (CFD) model that simulates the fluid flow, species transport and electric current flow in PEM fuel cells.Design/methodology/approach – The model makes use of a general‐purpose CFD software as a basic tool incorporating fuel cell specific submodels for multi‐component species transport, electrochemical kinetics, water management and electric phase potential analysis in order to simulate various processes that occur in a PEM fuel cell.Findings – Three dimensional results for the flow field, species transport, including waster formations, and electric current distributions are presented for two test flow configurations in the PEM fuel cell.

We use latent class analysis to categorize development experiences. This technique allows us to consider a broad range of country characteristics including per capita income growth, health, inequality, environmental performance, and life satisfaction. We show that each of these indicators is important in explaining the classifications based on the quality of growth. We then predict membership in growth quality classes using many of the standard determinants of growth. We find that they are related to growth quality in a non-linear way and that population growth is more consistently related to our broader measure of growth quality than is typically found in standard growth regressions.


Brazil is a country located in South America, with an area of 8,510,820.623 km2 [3], making it the fifth largest country in the world with an estimated population of 208,494,900 in 2018. The Gross Domestic Product (GDP) in 2018 totalled R$ 6.8 trillion, with a per capita GDP of R$ 32,747. Nevertheless, 15 million (7.4 %) people are below the poverty line with a per capita family income of less than US$ 1.90 per day, or approximately R$ 140.00 per month [4]. The measurement of critical restrictions to living conditions highlights that 28.2 % have restricted access to education [4], while the illiteracy rate of individuals aged 15 years or older reaches 7 % of the population [3]. Furthermore, 15 % of the population has restricted access to social protection and 13 % has restricted access to housing conditions, while 37.6 % suffer deprivations from a lack of basic sanitation and 25.2 % have communication restrictions (internet). The country is marked by inequalities, leading to the proposal of numerous initiatives to reduce inequality and ensure a life with better and more numerous opportunities for the population.


Although a number of elaborate color con- stancy algorithms have been proposed, methods such as Grey World and Max-RGB are still widely used because of their low computational costs. The Grey World algo- rithm is based on the grey world assumption: the average reflectance in a scene is achromatic. But this assumption cannot be always satisfied well. Borrowing on some of the strengths and simplicity of the Grey World algorithm, W. Xiong et al. proposed an advanced illumination esti- mation method, named Grey Surface Identification (GSI), which identifies those grey surfaces no matter what the light color is and averages them in RGB space. However, this method is camera-dependent, so it cannot be applied on the images from unknown imaging device. Motivated by the paradigm of the GSI, we present a novel iteration method to identify achromatic surface for illumination estimation. Furthermore, the local Grey Edge method is introduced to optimize the initial condition of the iteration so as to improve the accuracy of the proposed algorithm. The experiment results on different image datasets show that our algorithm is effective and outperforms some cur- rent state-of-the-art color constancy algorithms. � 2010 Wiley Periodicals, Inc.

We consider a new 1+1d, 2+1d and 3+1d sine-Gordon-type equation which differs slightly from the integrable 1+1d sine-Gordon equation. We have found exact solitary wave solutions to the new equation.


Paper as a material needs a lot of input energy. Many measures have been suggested to recycle paper, but still a huge amount of it ends in landfills. Hereby, one possibility for recycling paper - making paper plaster and putting it into service in indoor environment - is introduced. The study focuses on the moisture buffering properties of paper plaster. Two questions are under consideration in this article. Firstly, how paper type and production method influence the properties (dry density, drying shrinkage) of paper plaster, and secondly, what the material moisture buffering properties of paper plaster are. The plasters for testing were made from four types of paper (printer paper, glossy paper, newsprint and book paper). The production methods used were rumpling, grinding with a shredder or special crusher (prepared for the study) and soaking the paper after that. The dry density of groups varied from approx. 240 kg/m3 to 400 kg/m3. The shrinkage properties were from 3% to 10% in diameter. To evaluate the moisture buffering ability of paper plaster, the methodology introduced in the Nordtest protocol was used. Paper plaster is an outstanding water vapour buffering material [MBV=2.23-3.91 g/(m2·%RH)] belonging to the moisture buffering class "excellent" defined by Rode [15]. From the production methods rumpling gave the best value while printer paper showed the best values from the chosen materials. The tests with glossy paper resulted in modest values. To conclude, all the paper materials and preparation methods introduced in this study can be used to make paper plaster


Essential arterial hypertension (EG) is a multifactorial disease that occurs in 42% of the population over 35 years of age. This disease is an independent predisposing factor for cardio-vascular disease, including stroke, congestive heart failure and myocardial infarction. The pathogenesis of essential hypertension involves the genes of matrix metal proteinase (MMP), which are a family of zinc-dependent proteolytic enzymes that degrade various components of extracellular matrix and mediate remodeling in both physiological and pathological processes. The research is devoted to new data on the involvement of combinations of polymorphisms of matrix metal proteinase in the development of essential hypertension. A bioinformatic analysis was performed using the APSampler software. The study identified five combinations of MMP loci associated with the onset of НE, of which 3 had a protective effect, and 2 were risk factors for the development of hypertension. The most significant contribution to the formation of НE is demonstrated by polymorphisms rs11568818 MMP-7, rs11225395 MMP-8 and rs17577 MMP-9.


An important problem in navigation of a mobile robot is localization. The robot can estimate its location in a predefined environment by combining the information obtained from its sensors. There are various methods to combine the information obtained from sensors and the models used to estimate the position and velocity of the robot. In this paper, a decentralized data fusion algorithm is used, where the sensors are used in several independent estimation loops. Then, the estimates of these loops are exchanged to improve the accuracy of the position estimates. The sensors used in this study consist of a laser scanner, Kinect depth sensor, encoder and IMU, which are divided into two local loops. The algorithm was implemented in a real environment on a robot built at the Mechatronics Laboratory of the Department of Mechanical Engineering, Yazd University. It is observed that the decentralized estimates of the two loops track the real trajectory of the robot satisfactorily. It is observed that the precision of the decentralized approach is somewhat less than the accuracy of the centralized data fusion, since different kinematic models are used in the two loops and also due to asynchrony of the sensors data. However, the decentralized approach entails advantages such as robustness of estimation, possibility of error crosschecking and sensor failure detection.


The State Administrative Judicial as the executor of judicial power has a duty and authority to examine, decide, and resolve State Administrative disputes. Along with tecnological development, judicial practices within the scope of the Indonesian Supreme Court hal implemented the ecourt application.  The aims of this study is to analyze policies regarding the implementation of Electronic Litigation in the State Administrative Judicial, as well as to find the obstacles encountered. This study uses a normative method with a statute approach, that is Act 5 in 1986 concerning State Administrative Judicial and its amendment, and Supreme Court Regulation Number 1 of 2019 concerning Administration of Cases and Trials in Court Electonically. The result of the study show that the application of Electronic Litigation at State Administrative Judicial is carried out comprehensively, that is from the registration stage until reading of judicial decisions. The obstacles that still being faced are related to the stage of evidence which in practice still requires a conventional trial, and the limited access to the internet network in several regions in Indonesia.


The theory of fuzzy sets introduced by Zadehshould actually have been a generalization of the classicaltheory of sets in the sense that the theory of sets shouldhave been a special case of the theory of fuzzy sets.Unfortunately, this is not the case. It has been acceptedthat for a fuzzy set A and its complement A c , neither A  A c is the null set, nor A Ac is the universal set.Whereas the operations of union and intersection of twocrisp sets are indeed special cases of the correspondingoperations of two fuzzy sets, they end up giving peculiarresults while defining A Ac and A Ac . In thisregard, H. K. Baruah proposed that in the currentdefinition of the complement of a fuzzy set, fuzzymembership function and fuzzy membership value hadbeen taken to be the same, which led to the conclusionthat the fuzzy sets do not follow the set theoretic axiomsof exclusion and contradiction. For the complement of anormal fuzzy set, fuzzy membership function and fuzzymembership value are two different things, and thecomplement of a normal fuzzy set has to be definedaccordingly. H. K. Baruah has reintroduced thedefinition of fuzzy set and redefined the complement of afuzzy set accordingly. In 1999, Molodstov introduced thetheory of soft sets, which can be seen as a newmathematical approach to vagueness. The theory offuzzy soft set, a more generalized concept, initiated byMaji, is a combination of fuzzy set and soft set. In thispaper, we improve the notion of union and intersection offuzzy sets proposed by Baruah and generalize theconcept of complement of a fuzzy set when the fuzzyreference function is not zero. We are defining arbitraryfuzzy union and intersection using the definition of fuzzysets given by Baruah and then we are using thisdefinition of fuzzy set and newly defined complement inthe fuzzy sets occurring in a fuzzy soft set so that fuzzysoft sets, too, follow the axioms of exclusion andcontradiction. Accordingly we propose some new notionsregarding fuzzy subset, null fuzzy soft set, absolute fuzzysoft set, complement of a fuzzy soft set. We put forwarddefinitions of "AND" and "OR" operations for anarbitrary collection of fuzzy soft sets and finallyDeMorgan inclusions and DeMorgan laws proved byAhmad and Kharal in fuzzy soft set theory have beenverified according to our new notions.


The prophet Samuel's declaration of משפט המלך to the assembled Israelites in 1 Sam 8:11-18 has generally been understood in the history of scholarship as a cat alogue of monarchic excess. Scholarly interpretations of this passage enumerate various literary parallels found in both biblical and nonbiblical texts. These pur ported parallels include memories of the reign of Solomon by a later writer, descrip tions of Canaanite royal practices preceding the start of the Israelite monarchy, and accounts of Assyrian royal behaviors close in time to the composition and redac tion of the Deuteronomistic History (DtrH). This article shifts focus away from charting specific literary parallels to 1 Sam 8:11-18 in other ancient Near Eastern texts. I argue instead that 1 Sam 8:11-18 takes inspiration from a diverse group of literary materials and rituals designed to constrain monarchic power, the excesses of which brought ruin on cult and country. These diverse materials range from the Babylonian Fiirstenspiegel to priestly rituals that are part of the Babylonian New Year festival. Together they constitute a "genre of discourse," a term coined by Tzvetan Todorov to describe how diverse literary and nonliterary materials can


We report a carboxylate triangle consisting of three manganese(II) centres which is made from manganese(II) carbonate and pivalic acid. The magnetic exchange within the triangle is extremely weak, and antiferromagnetic. Several models have been used to fit the magnetic data, and the best fit uses two weak antiferromagnetic coupling constants of J(1)=-0.588 cm(-1) and J(2)=-0.855 cm(-1). Exchange interactions between the metal centres has been calculated using DFT adopting all the three possible Heisenberg models for a trinuclear system and the results are compared with experimental values. Spin density distribution is used to analyse the nature of the coupling between the metal centres. EPR spectroscopy has been used to explore the nature of the ground state. Recrystallisation of the trinuclear compound from MeCN gives a polymer, while oxidation in air leads to a known compound--an edge-sharing bitetrahedral (MnIII2MnII4) cage.


For the first time in human history the global atmospheric CO2 concentration has surpassed 400 ppm and is projected to reach 600–800 ppm by A.D. 2100. A positive feedback in average global temperatures relating to an increase in CO2 levels in the upper atmosphere has been well-documented. With a global warming potential 25 times that of CO2 over 100 years, CH4 is also considered to be a significant greenhouse gas. Understanding and managing the exchange of CO2 and CH4 between the geosphere and atmosphere as a part of the global carbon cycle is consequently an important geotechnical engineering challenge of the 21 Century. A conceptual model of ground gas dynamics in the near-surface was developed with wider implications for the geotechnical engineering industry activities in the nearsurface and deep subsurface. Evidence was collated from historic gas monitoring data, high temporal frequency gas monitoring data, stable isotope analysis, and modelling and measuring gas transport mechanics in order to compile a conceptual model. Historic ground gas monitoring of landfill sites provided an extensive data resource. Routine point measurement of CH4 and CO2 in the sub-surface has not enabled gas transport mechanisms to be fully understood. Emission events may be overlooked by this method. By monitoring gases at high temporal frequency (up to every three minutes) this study has attempted to resolve the relationship between ground gases and the atmosphere. As a result, barometric pumping was proven to be a major control on CH4 and CO2 emissions from the near-surface. Data yielded from a high temporal frequency gas monitoring campaign in 2013, showed that an average pressure gradient of −0.7 mbar/hr was sufficient to induce a gas release from the near-surface comprising 40.1% CH4 and 7.9% CO2. The cycling of air and ground gases was shown to be rapid, often occurring over three hours or less. Crucially, only air was present in the test borehole for 70% of the period indicating the fragility of point measurement strategies.


This paper addresses the speed and accuracy problems in human face recognition. The wavelet transform is adopted to decompose an image and a particular frequency band is selected for principal component analysis (PCA) for face recognition. Experimental results show that the proposed method is better than the original PCA method in terms of both speed and accuracy.


Safety is a major issue in the embalming procedures of human cadavers. Reduced application of formaldehyde is often recommended. The aim of this study was to investigate the potency of ultraviolet light (UV‐C irradiation) on the bacterial load on the surface of a conserved human cadaver. To test UV‐C irradiation, the cadaver was laid out in the dissection hall and, after preparation of the muscles, was covered with linen sheets moistened with water. Swabs of the surface and microbiological analysis revealed sporadic bacterial colonies. The surface area was then spiked with bacteria and irradiated by a UV lamp for 15 or 60 min. Half of the area was covered by aluminum foil to serve as a control. After exposition, swabs were taken and analyzed. The exposition had reduced the number of colonies to one third (15 min exposition) and to one tenth (60 min exposition) of the control area. Thus, UV‐C irradiation could be used in the preservation of cadavers without chemical pollution of the environment and without any risk for the employees. Clin.

The memristor, known as the fourth basic two-terminal circuit element, has attracted many research interests since HP labs were able to develop the device based on what L. Chua predicted theoretically. The memristor is a potential contender for the next-generation memory due to its distinctive characters, such as non-volatility, non-linearity, low-power consumption, good scalability and its ability to store multi-bit values. These electrical characteristics of memristors are mainly determined by the material characteristic and the fabrication process. However, the manufacturing of memristors is facing various challenges due to the difficulty of controlling its process variation, as it is fabricated at nano-scale geometry's size. These process variations lead to deviation in results from the theoretical results which lead to reduction in the reading yield. In this paper, we present the multi-bit memristor and we investigate the effect of the memristor size and the process variations effect on the multi-bit memristor and how we can maximize the reading yield.


This paper will describe the results of the preliminary phase of a NASA design study for a facility to test high-power electric propulsion systems in space. The results of this design study are intended to provide a firm foundation for a subsequent detailed design and development activities leading to the deployment of a valuable space facility supporting the new vision of space exploration. The objectives for human and robotic exploration of space can be accomplished affordably, safely and effectively with high-power electric propulsion systems. But, as thruster power levels rise to the hundreds of llowatts and up to megawatts, their testing will pose stringent and expensive demands on existing Earth-based vacuum facilities. These considerations and the access to near-Earth space provided by the International Space Station (ISS) have led to a renewed interest in space testing. The ISS could provide an excellent platform for a space-based test facility with the continuous vacuum conditions of the natural space environment and no chamber walls to modify the open boundary conditions of the propulsion system exhaust. The platform would be designed to accommodate the side-by-side testing of multiple types of electric thrusters currently under development and thus provide a strong basis for comparing their relative performance. The utility of testing on the station is further enhanced by the human presence, enabling close interaction with and modification of the test hardware in a true laboratory environment. These conditions facilitate rapid development and flight certification at potentially lower cost than with conventional Earth-bound facilities. As an added benefit, the propulsive effect of these tests could provide some drag compensation for the station, reducing the re-boost cost for the orbital facility. While it is expected that the ISS will not be capable of generating continuous levels of high power, the utilization of state-of-the-art energy storage media would be sufficient to achieve very high power levels over intervals short enough to be feasible and long enough to provide ample demonstration of steady-state operation. This paper will outline the results of the preliminary phase of the design study with emphasis on the requirements that will dictate the system design. These requirements will be based on the collaborative work of the Electric Propulsion Branch at the NASA Glenn Research Center, the Propulsion Research Center at the NASA Marshall Space Flight Center and the Advanced Space Propulsion Laboratory at the NASA Johnson Space Center along with International Space Station program representatives. Furthermore, the requirements will reflect the inputs of the broader electric propulsion development community including those at universities, commercial enterprises and other government laboratories. As a facility on the International Space Station, the design requirements are also intended to encompass the needs of potential international users. High-power electric propulsion systems now in development can effectively meet the challenges of human and robotic space exploration with affordability, reliability and safety and enable missions not possible with other propulsion systems. These systems can operate with extremely low propellant consumption thus dramatically reducing the initial launch mass, vehicle scale and cost. They do not require combustion, have few, if any, moving parts and, in some cases, do not require electrodes. These are features that extend system lifetime and increase reliability. High-power electric propulsion systems will significantly reduce trip times and thereby minimize crew exposure to radiation and micro-gravity conditions. Since electric propulsion systems typically provide continuous thrust, the opportunities for mission aborts and other contingency operations are greatly improved, especially if the propulsion system can adjust its thrust and specific impulse (Isp) as needed. Testing of high power electric propulsion technologies will pose stringent and expensive demands on existing Earth-based facilities. For power levels in the megawatt range, pumping speeds in excess of lo6 liters per second will be required in order to maintain acceptable conditions in the exhaust region. As illustrated in Figure 1, a thruster using Xenon propellant, for example, operating at 5000 sec Isp or less, could not be tested above 100 ktlowatts. Thrusters using lighter gases are of particular interest for future exploration missions and as shown in Figure 1, their testing is even more severely limited even at modest power levels. In addition, the presence of chamber walls modifies the open boundary conditions of plasma rockets, affecting the measurements and hence the assessment of the true system performance. These considerations and the growing human access to near-Earth space, as compared to two decades ago, have led to a renewed interest in space testing. High-power electric propulsion systems for deep-space missions will likely be powered with electricity supplied by a nuclear reactor. However an important feature of these propulsion systems is that they can also be tested and operated with solar-generated power when that is appropriate. As a facility for testing electric propulsion devices, the ISS could provide a structural attachment, a supply of electrical power, a data link for control and measurements, thermal management, a means to observe the system performance and access for occasional servicing. If a propulsion device needs to be tested at a power level greater than the Station can provide continuously, energy can be stored for periodic testing. l o 6 Us Vacuum Chamber 500


Due to their unique scintillation, phosphorescence, magnetic, and catalytic properties, rare earth oxide compounds have recently become one of the most in-demand materials used in different ways. The current study investigated the impact of Ar:O2 gas flow variation on the deposition of La2O3-doped zinc oxide thin films (TFs) on silicon dioxide (SiO2) substrates using the radio frequency sputtering technique. FE-SEM analysis has shown a smooth surface topology and purity of La2O3-doped ZnO TFs. X-ray diffraction analysis exhibited a single-phase hexagonal wurtzite-type structure in TFs. A UV–Vis–IR spectrophotometer examined the optical characteristics of ZnO and La2O3-doped ZnO TFs in 300–800 nm wavelength range. The bandgap of La2O3 doped ZnO TFs changed from 2.9 to 3.1 eV as argon and oxygen concentrations in (Ar:O2) gas flow changed. A variation in optical constants such as dielectric constants, refractive index, and extinction coefficient was observed when ZnO and La2O3-doped ZnO TFs were exposed to variable (Ar:O2) gas flow ratios. The photoluminescence analysis of ZnO and La2O3-doped ZnO TFs was performed at an excitation wavelength of 330 nm. Atomic force microscopy further revealed that La2O3 doping resulted in smoother surfaces and smaller grain sizes. This comprehensive study provides valuable insights into the relationship between doping, gas composition, and the optical and structural properties of ZnO TFs. The obtained results on the optimal flow rate of argon gas provide valuable insights for determining the appropriate deposition conditions of La2O3-doped ZnO TFs, specifically for their application in solar thermal systems.


Testing technology curriculum is abstract and has strong practical demand, which leads to the fact that the teaching is much more difficult. The article firstly analyses the problem of traditional teaching and then put forward to a new method, which includes adjusting the content sequence, highlighting teaching points, using project approach, strengthening the students' ability of doing experiments.

In dealing with numerical values for relative intensities derived from the Debye‐Scherrer technique, the alteration of diffracted intensities produced by absorption in the sample cannot be ignored. Claassen has shown how this effect can be allowed for in the case of homogeneous cylindrical samples. This paper deals with a sample consisting of a cylinder surrounded by another annular cylinder both when the core is inert (i.e., absorbing and producing only extraneous scattering) and when the annulus is inert. The method is applied to show how the diffraction pattern for a liquid enclosed in a glass container may be corrected for the diffuse diffraction of the container as well as for absorption in the liquid and in the glass.


Summary An overnight fast resulted in decrease in weight of liver of rats and mice with a proportionate decrease in their aspartic- and alanine-glutamic transaminase activities except for the aspartic-glutamic transaminase of mouse liver which maintained its total activity. Homogenates of liver and heart prepared in water had the same alanine-glutamic transaminase activities as those prepared in 0.05 M potassium phosphate (pH 7.4) but the kidney enzyme was lower in buffer. The aspartic-glutamic transaminase activities of liver and kidney were higher in water homogenates while that of the heart was higher in buffer.


Abstract. Competition is a major driver of carbon allocation to different
plant tissues (e.g., wood, leaves, fine roots), and allocation, in turn,
shapes vegetation structure. To improve their modeling of the terrestrial
carbon cycle, many Earth system models now incorporate vegetation
demographic models (VDMs) that explicitly simulate the processes of
individual-based competition for light and soil resources. Here, in order to
understand how these competition processes affect predictions of the
terrestrial carbon cycle, we simulate forest responses to elevated
atmospheric CO2 concentration [CO2] along a nitrogen availability
gradient, using a VDM that allows us to compare fixed allocation strategies
vs. competitively optimal allocation strategies. Our results show that
competitive and fixed strategies predict opposite fractional allocation to
fine roots and wood, though they predict similar changes in total net primary production (NPP) along
the nitrogen gradient. The competitively optimal allocation strategy
predicts decreasing fine root and increasing wood allocation with increasing
nitrogen, whereas the fixed strategy predicts the opposite. Although
simulated plant biomass at equilibrium increases with nitrogen due to
increases in photosynthesis for both allocation strategies, the increase in
biomass with nitrogen is much steeper for competitively optimal allocation
due to its increased allocation to wood. The qualitatively opposite
fractional allocation to fine roots and wood of the two strategies also
impacts the effects of elevated [CO2] on plant biomass. Whereas the
fixed allocation strategy predicts an increase in plant biomass under
elevated [CO2] that is approximately independent of nitrogen
availability, competition leads to higher plant biomass response to elevated
[CO2] with increasing nitrogen availability. Our results indicate that
the VDMs that explicitly include the effects of competition for light and
soil resources on allocation may generate significantly different
ecosystem-level predictions of carbon storage than those that use fixed
strategies.

The invention relates to a plan and fault power failure range visualization method based on a power grid GIS. The method comprises the following steps: production first-aid repair platform power failure event information is generated; coordinates of the faulted medium-voltage devices and low-voltage users are confirmed; the medium-voltage devices influenced by power failure are marked, including power protection users, important users, and buildings in which highlighting rendering low-voltage user sets are located; device account information of the medium-voltage devices including the power protection users and the important users is displayed; and power consumption curves of the low-voltage users according to time change is displayed. The medium-voltage devices and the low-voltage users influenced by fault power failure are visually displayed so that full and accurate basis is provided for fault processing. Distribution transformer load information within a period of time can be examined in a real-time way, and normality of power supply of the distribution transformer is judged. Meanwhile, the low-voltage user information and the power consumption information are displayed so that location and number of the buildings influenced by power failure are visually examined, the fault power failure range is updated in the real-time way, and thus powerful support is provided for production first-aid repair decisions.


A freely falling experiment, in which a metal droplet fell freely and impinged on a flat substrate, was conducted as a simulation of the thermal spray process. The effect of substrate temperature on the flattening and solidification of the droplet was mainly investigated in this study.The transition of the splat pattern was recognized in the experiment, that is, the splat morphology of Ni and Cu droplet on the room temperature substrate was splash-type, while that on the high temperature substrate was disk-type. The cross section microstructure of the splat on the room temperature substrate was composed of an isotropic coarse grain, while that on the high temperature substrate was quite fine columnar structure. As the mean interparticle spacing in the splat changed transitionally with the substrate temperature, the solidification rate in the splat on the high temperature substrate was higher than that on the room temperature substrate. The unique porous microstructure and flowing pattern were observed in the bottom surface of the splat on the room temperature substrate while the flat microstructure without pore was recognized in that on the high temperature substrate. The difference of the solidification rate between these two kinds of splats seems to be attributed to the interface microstructure between splat and substrate. From the results obtained in this study, it can be concluded that the quite rapid solidification occured at the interface between splat and substrate when the droplet impinged on the cold substrate surface.

Anaerobic digestion allows to produce sustainable energy but the microbial community involved in this process is highly sensitive to perturbations. In this study, a longitudinal experiment was performed in two sets of triplicate bioreactors to evaluate the influence of ammonia addition on AD microbiome and its recovery. Zeolite was added in three reactors to mitigate the inhibition. Microbial dynamics were monitored with 16S rRNA sequencing at 15 time points. Dominant methanogenic pathways were determined with gas isotopic signature analysis. Zeolite addition did not enable to reduce ammonia inhibition or improve the process under the conditions tested. In all the bioreactors, ammonia inhibition sharply decreased the methane production but the process could restart thanks to the increase of hydrogenotrophic archaea and syntrophic bacteria. Interestingly, similar behaviour was observed in the six reactors. Neutral modelling and null model were used and showed that a deterministic process governed the recovery of AD microbiome after failure.


Two ways of improving durum wheat bread-making quality were evaluated.

First, durum wheat (cultivar "Papadakis") was blended with bread wheat flour of good (A-flour) or medium (B-flour) quality (70% durum and 30% bread wheat flour). Durum wheat flour displayed the γ-gliadin 45 electrophoretic band and acceptable bread-making quality. Breads from flour blends had better volume, particularly the durum and A-flour blend. The addition of ascorbic and citric acid and malt flour improved dough rheological properties and thus bread volume, as well as staling rate and sensory characteristics. These were more pronounced in the blend of durum with B-flour.

Second, durum wheat flour alone was used to prepare chickpea sourdough-leavened bread, as flavor is important for consumer acceptance. With the addition only of salt, the chickpea sourdough-leavened durum wheat bread displayed acceptable loaf volume, distinguished flavor and longer shelf life compared with bread prepared with compressed baker's yeast.

PRACTICAL APPLICATIONS

One of the practical applications of this study is the possibility of using a common durum wheat cultivar instead of local varieties as is the case with traditional breads. Results of this work may be useful for promoting greater acceptance of durum wheat breads as well as expansion of the use of a traditional Mediterranean chickpea sourdough-leavened durum wheat bread with distinguished flavor and taste.

This work may serve as a guide for determining the quality of flours suitable for production of "home made" or "village" bread (which has high market value as specialty bread) by blending durum and bread wheat flours. Best results are obtained with good-quality bread wheat flour, regardless of the good quality of durum wheat cultivar used, together with the use of the dough improvers implemented in this work.


T HE SCHEME of the thirty books of the Histories of Ephorus was an account of the world as a Greek of the fourth century knew it: it included the rise of the Greek states, their activities in the Mediterranean, and their relations with the neighbouring kingdoms. Ephorus laid down the principle that the myths of a remote past were outside his province, because their truth was not ascertainable. However, he chose to begin his work with what we call the Dorian Invasion, which was known to him by legend under the title "Return of the Heracleidae."l He recounts the mythical foundation of Delphi's oracle in the fourth book of his Histories (F 31). Strabo, introducing this passage of Ephorus, criticises the rationalized view employed by the historian in the myth of the founding of Delphi and attacks the half-hearted rationalization as merely a confusion of history with myth.2 The approach of Ephorus is considered rationalistic or euhemeristic.3 For Jacoby (ad F 31) Ephorus treats two traditions as interwined: on the one hand he puts Themis and Apollo together, and on the other through the rationalization of Python includes the struggle for the site of Delphi.

In this study, a two-step crosslinking method derived from commercial rapid prototyping equipment was used to fabricate a gradient hydrogel scaffold in vitro. This system contained two types of nozzles; one was double-nozzle unit, used for relatively simple gradient hydrogel scaffold composed of two nonmiscible hydrogel materials. The other was single nozzle that was used for mixing a gradient hydrogel scaffold composed of two types of hydrogel materials. Different types of scaffolds were formed by modifying the gradient in one of the relevant nozzles. To improve the extrusion controlling effect, accessorial parameters were introduced. A 3D gradient construct containing neuron cells and Schwann cells was fabricated and cultured for 7 days. This construct was helpful in designing a gradient mode to observe the relationship between different cells in vitro. This work has improved tissue-engineering techniques for later manufacturing of very complicated organ analogs.


Abstract : This research investigated the influence of exercise activities, situational factors, and personality on the Air Force submaximal cycle ergometry test (SCET). Data were collected via a questionnaire administered to 209 active duty students and faculty assigned to the Air Force Institute of Technology during their required annual SCET. Stepwise multiple regression and ANOVA were used to find the proportion of variance explained by the significant predictors of SCET results for various subsets of the sampled population. For the group as a whole, self-reported test anxiety explained 24% of the variance in SCET results, while reported aerobic caloric expenditure during exercise explained only 10%. For runners, test anxiety explained 26% and calories expended running explained only 5% of the variance in SCET results. For cyclists (outdoor and stationary), calories expended cycling explained 53% of the variance, while test anxiety had no influence on SCET results. These results indicate that for non-cyclists, test anxiety plays a major role in SCET performance while aerobic exercise plays only a minor role. Non-cyclists who reported high levels of anxiety about the SCET generally received lower SCET scores. The results also indicate that cyclists have a clear advantage over individuals who participate in other exercise activities.


Women was excluded from the mainstream discourse right in China's ancient society, although in ancient Chinese marriage drama women are the absolute protagonists, but actually they are in " the supporting roles" by male playwrights. From the function of the first female supporting role, they are in a great extent shape with the psychological needs and ways of thinking by the male, they are the shape of a male writer on women with male color recessive, and they are the carrier of the male-dominated discourse.


Purpose: The aim of this study was to examine the frequency of anatomical variations of thesinonasal region detected by Computed Tomography (CT) and, to investigate their roles onparanasal sinus infections.Methods: In this study, coronal section CT images of 120 patients who were admitted to ourhospital's Ear, Nose and Throat Clinic with sinonasal complaints between January 2012 andNovember 2012 were retrospectively reviewed. Sinonasal anatomical variations detected by CTimaging and their relationships with the mucosal pathologies of paranasal sunuses were alsoinvestigated.Results: On paranasal CT imaging, major variations in order of their frequency were Aggernasi cells (47.5%), concha bullosa (34.2%), septum deviation (31.2%), septum pneumatization(24.5%) and paradoxical middle concha (17.5%). Of these cases, 55% were associated withmucosal pathologies and maxillary sinuses were the most frequently involved sinus. Paradoxicalmiddle concha, Agger nasi cell, septum pneumatization and septum deviation were frequentlyencountered with mucoperiosteal pathologies whereas Onodi and Haller cell seemed to associatesinus pathologies less commonly.Conclusion: Sinonasal anatomic variations are closely related with occurrence of paranasalsinus infection. CT is the most effective diagnostic tool for evaluation of these variations.Considering and reporting of these variations are important because preoperative identificationof these anatomic variations gives advantage to the surgeon for choosing the operation type aswell as clarify the reason of the sinonasal complaints


Orthogonal frequency division multiplexing (OFDM) is prone to frequency offset which gives rise to intercarrier interference (ICI). Recently, a novel OFDM transmission scheme called OFDM with index modulation (IMOFDM) is proposed, which outperforms conventional OFDM in the absence of frequency offset. As in IM-OFDM, partial subcarriers are set to be idle by spatial modulation, the potential of IM-OFDM in ICI reduction is expected. In this paper, we find that this potential vanishes in some real scenarios with ICI, which leads to IM-OFDM exhibiting even worse performance than conventional OFDM. To improve this situation, a novel ICI cancellation scheme is designed, which integrates the ICI self-cancellation technique into the IM-OFDM framework. Via careful designs, the proposed scheme not only provides a solution to ICI problems of IM- OFDM, but also achieves an attractive tradeoff between the spectral efficiency and ICI cancellation performance of the system. Simulations validate that in the presence of carrier frequency offset (CFO), the proposed scheme significantly outperforms existing IM-OFDM and more importantly shows better performance than the conventional OFDM with ICI self-cancellation.


We study a possibility of the dynamical formation of traversable wormholes from gravitationally collapsing exotic matter clouds. For generic metric ansatz of exterior spacetimes, a crucial constraint that black holes and wormholes should satisfy is obtained through the junction conditions on the edge. As a result, it is shown that the wormhole geometry cannot be formed by following the usual Oppenheimer-Snyder type gravitational collapse of the exotic matter. Instead, it is also shown that the wormhole geometry immediately appears once the exotic matter is taken into account. PACS numbers: 04.20.-q, 04.90.+e, 97.60.Lf


The results of non-destructive technological control of the number of defects in the enamel wire insulation based on polyetherimide polymer are presented. The application of statistical analysis of the measurement results of control indicators with the help of a mathematical trend model for the use in active technological control is considered. Recommendations for the practical use of the trend function parameters to control the probability of finding several parameters within the established limits are proposed. The main parameter of the trend is the flow parameter of the number of defects exceeding the established technological limit (the failure flow parameter) in short periods of the technological time, for example, for each spool of wire (several thousand meters of wire). The ability to quantitatively assess the tendency of enamel insulation defects for the wire with two-layer insulation with a nominal diameter of 0.63 mm during a continuous technological cycle has been theoretically explained and confirmed by measurements. Quantitative assessment of the tendency of changing the enamel insulation defectiveness allows using a model based on collating the information on a significant number of control parameters. At the same time, one parameter of the spectrum of interrelated ones is allowed to exceed a set technological limit, which ensures sensitivity to changes in this limit. Data on the sensitivity of this model to technological changes are presented


The diurnal and seasonal variations of aerosol optical depth,atmospheric precipitable water and Angstrom exponentαwere analyzed,based on data derived from CE-318 observation in the Semi-Arid Cli- mate andEnvironment Observatory of Lanzhou University during Aug,2006,Jul,2007;the relationship betweenτand conventional temperature,relative humidity,pressure,PW and Angstrom wavelength expo- nent were analyzed well.A correlation analysis between PW measured by CE-318 and the integrated water vapor inverted by microwave radiometer's neural network algorithm was made and the result shows that they have the same capacity for measuring integrated water vapor.


Images, symbols and fable making are the pulse of fiction, and are necessary for the expression and understanding of foundational emotions, as well as psychic and spiritual repercussions.  Simultaneously, fable making gives meaning to an event whose repletion expands in the retelling of the story and in cyclic temporality.  This fictional impulse gives meaning to human life, and, specially, to creation.  Since the beginnings of human existence the impulse to try and understand contingence and overcome it have been fundamental, leading toward transcendence.  The pulse of fiction, as it presents itself, is also a foundation of understanding and of the constitution of human identity.  In the degree to which a hypothesis regarding post-modernity is the emptying of the subject, post-modernity will see the subject as purely empty, having lost its ipseidade.  But the impulse of fiction, imagination, and symbolization, the impulse for overcoming and for transcendence makes us understand that there exists a constructive alternative of responsibility in the relationship I- Thou.  This relationship needs to be preserved, and fed, for the preservation of ipseidades in human beings, as well as to affirm and confirm the desire for knowledge.


Following the 1998 nuclear tests in South Asia and later reinforced by revelations about North Korean and Iraqi nuclear activities, there has been growing concern about increasing proliferation dangers. At the same time, the prospects of radiological/nuclear terrorism are seen to be rising - since 9/11, concern over a proliferation/terrorism nexus has never been higher. In the face of this growing danger, there are urgent calls for stronger measures to strengthen the current international nuclear nonproliferation regime, including recommendations to place civilian processing of weapon-useable material under multinational control. As well, there are calls for entirely new tools, including military options. As proliferation and terrorism concerns grow, the regime is under pressure and there is a temptation to consider fundamental changes to the regime. In this context, this paper will address the following: Do we need to change the regime centered on the Treaty on the Nonproliferation of Nuclear Weapons (NPT) and the International Atomic Energy Agency (IAEA)? What improvements could ensure it will be the foundation for the proliferation resistance and physical protection needed if nuclear power grows? What will make it a viable centerpiece of future nonproliferation and counterterrorism approaches?


Exactly measuring the degradation degree of land ecosystem is the basis and precondition of restoring ecosystem. In this paper, quantitative classification method was used to study the degradation degree of ecosystem in karst mountain areas of Chongqing city, which was measured by the degradation degree of plots under different land use patterns. The results shows that the land ecosystem degradation types may be divided into 4 types according to soil fertility and vegetation status, and all the secondary woodland's woodlands'ecological status were rehabilitated in some degrees than the barren karst grass hills, which distributed in a large area compared with the primeval vegetations. The measurement of soil quality and ecological state degradation degree of barren grass hills and woodlands provided theoretical basis for ecology restoration practice of the limestone barren hills.


This study aims to increase ETL process efficiency »ud reduce processing time by applying the method of Change Data Capture (CDC) in distributed system using Hadoop Distributed file System (HDFS) and Apache Spark in the data warehouse of Learning Analytics system of Universitas Indonesia. Usually, increases in I lie number of records in the data source result in an increase in ETL processing time for the data warehouse system. This condition occurs as a result of inefficient ETL process using the full load method. Using the tull load method, ETL has to process the same number of records as the number of records in the data sources. The proposed ETL model design with the application of CDC method using HDFS and Apache Spark can reduce the amount of data in the ETL process. Consequently, the process becomes more efficient and the ETL processing time Is reduced approximately 53% in average.

A configuration with cascaded ring-resonators is designed and demonstrated for realizing multi-channel optical sensing with reduced temperature sensitivity. The present configuration integrates a microring-based 1 x N wavelength-selective power splitter and N microring transducers. The 1 x N wavelength-selective power splitter serves as a 1 x N power splitter and N bandpass optical filters, which helps realize a compact chip with an optical sensor array. As an example, a sensor array with three microring transducers is demonstrated by using silicon-on-insulator nanowires. The present multi-channel optical sensor tolerates a temperature variation within ~10 °C.

Introduction. Coronary hagiography revealed 70%-prevalence of multivessel coronary lesions. Chronic coronary occlusion (CCO) occurs in approximately 20 % of patients with coronary heart disease. Endovascular recanalization of CCO is associated with technical difficulties and the risk of complications. In this regard, patients with CCO rarely undergo revascularization, which leads to incomplete myocardial revascularization.Materials and methods. Patient M., male, 64, was hospitalized at the National Medical Research Center for Therapy and Preventive Medicine in February 2020 with a diagnosis of CHD. Stable angina, FC III, multivessel coronary lesions. The recanalization of chronic occlusion of the right coronary artery was performed at the first stage. During the next stage of revascularization of the left main coronary artery, an acute occlusion of the circumflex artery occurred. Despite the acute occlusion, no ischemic dynamics wasm reported on the electrocardiogram, there were no complaints, hemodynamics was stable. Ischemic events did not occur due to the formed network of collaterals out of the system of the right coronary artery. This allowed the complication to be corrected without consequences for the patient. Results and discussion. Thanks to the accumulated experience and advanced technologies, the success rate of recanalization has reached 90–95 %, and complications are not more common than in cases of stenting of non-occlusive lesions. The conducted studies have proved that successful recanalization of CCO improves the patient's clinical and functional status, intracardiac hemodynamics and quality of life.Conclusion. The clinical case given above clearly demonstrates the need for endovascular revascularization of CCO. The formed collateral network ensured blood flow in the area of acute occlusion and prevented the development of ischemia and myocardial infarction.


Allergic rhinitis has increased in the last fifty years from affecting less than a percent to more than twenty-six percent of the population[1]. Today, more than one hundred million people in the US suffer from these seasonal or yearlong allergies[2]. The hygiene hypothesis was proposed 30 years ago as a potential explanation for this phenomenon[3], and we built on that with the specific oral hygiene hypothesis[4]. Our longitudinal pilot study suggested that oral probiotic deficiency is the cause of allergic rhinitis[5]. This clinical trial served to verify our theory and evaluate the effectiveness of AllerPops for allergy relief. Through it, we show that AllerPops prebiotic supplements are effective in providing sustained allergy relief (p = 0.002) and can modulate oral beneficial bacteria that produce short-chain fatty acids (SCFA), such as Fusobacteria, Butyrivibrio, and Peptostreptococcus. The clinical improvements correlated with changes in the relative abundance of probiotics significantly: Fusobacteria (R = 0.32, p = 0.009), Butyrivibrio (R = 0.25, p = 0.044), and Peptostreptococcus (R = 0.34, p = 0.005). These results point to the root cause of allergic rhinitis: the lack of oral probiotics that produce SCFA to pacify the immune systems. Future study of AllerPops theory will help society redefine the best oral hygiene practice to protect oral probiotics so that we may prevent both allergies and dental/gum diseases. The trial was retrospectively registered at clinicaltrials.com, with registration number NCT05956691, on July 20,2023.


The development of morphological processing has been the focal topic in a debate over the nature of language, learning, and the mind in cognitive science. Particular attention has been paid to the systematic nature of children's early morphological errors. Because these errors aren't explicitly corrected, it has been argued that the transition to adult language cannot be explained by learning, and that the acquisition of even relatively simple aspects of grammar must involve innate, language-specific mechanisms. We describe the background to this debate, along with a model of the learning of noun morphology based on formal learning theory. This model generates clear and surprising predictions, which are then validated empirically. These results indicate that when the learning problem facing children is properly characterized, over-regularization is not a mystery. Rather, it arises and is subsequently resolved as a result of the discriminative nature of human learning systems, and the properties of the linguistic environment. Taken together, the models and results we review here indicate that, far from being evidence for language-specific mechanisms, the behavior manifest in over-regularization bears all the hallmarks of basic learning mechanisms, which we share with a number of other animals. We discuss the implications of this for our broader understanding of language and learning, as well as the nature of human communication.

Multiloop networks is a family of network topologies which is an extension of the ring topology. In this thesis we study the structural properties of bipartite double loop networks using the plane tessellation technique. We also study the problem of broadcasting in the bipartite double loop networks and in triple loop networks. For the first kind of graphs we find that the broadcast time is d + 2 where d is the diameter of the graph. For the triple loop graphs, we give a d + 5 upper bound on the broadcast time by providing an algorithm that completes broadcasting in at most d + 5 time units. We also find a d + 2 lower bound for the optimal triple loop graphs, these are the graphs with maximum number of nodes given a diameter d . Finally we give an upper bound for the broadcast time of undirected Circulant (also called multiloop) graphs of degree 2 k which is d + 2 k - 1


Objective To evaluate the clinical significance of determining the serum transforming growth factor beta-1(TGF-β1) in the patients with chronic viral hepatitis B(CHB).Methods Fifty-six patients with CHB and 20 healthy persons were selected.Their serum level of TGF-β1 was determined with enzyme linked immunosorbant assay.Their liver function,serum fibrosis markers,internal diameter of portal vein and portal vein of spleen,were also determined simultaneously.The patients were treated with regular project for 3 months,then their ameliorative level of liver function and fibrosis markers were determined.Results The serum level of TGF-β1 of patients with CHB was significantly higher than that of normal controls(P 0.01) and increased significantly with developing of the disease.The order was normal controlmildmediumsevereliver cirrhosis(P 0.01).The serum level of TGF-β1 of patients was correlated with albumin(ALB) negatively and correlated positively with total bilirubin(TBIL),hyaluronic acid(HA),laminin(LN),N-terminal peptide of type Ⅲ procollagen(PⅢNP),type Ⅳ collagen(CⅣ) and internal diameter of portal vein of spleen.After 3 months of regular project for CHB,the serum level of TGF-β1 correlated with the ameliorative level of alanine aminotransferase(ALT),HA,PⅢNP negatively.Conclusion TGF-β1 was closely involved in the damage course of liver cells and liver cirrhosis of patients with CHB .The serum level of TGF-β1 reflects the level of liver function,the level of liver cirrhosis and the prognosis,which has a higher practical value.


This article deals with the social movement that erupted in Central Chile during the 1810-1820 decade, examining the upsurge of popular montoneros who, contemporary to the monarchists and free Mapuche Indians resistance, challenged the Republican project. Cipriano Palma, Jose Maria Zapata, Pablo Pincheira y Vicente Benavides, amongst others, emerge as the leaders of those plebeian guerillas that forced the displacement of revolutionary forces from Concepcion to Santiago; it also quotes official reports of hundreds of marauders, thieves and bandits who runsacked resources from local villages and the countryside. It postulates that subaltern social groups took advantage of the power vacuum created by the 1810 Revolution, took up arms and, thus armed, withstood the installation of a political regime monopolised by the creole aristocracy. This account also defies official history, which is centered exclusively around the facts derived from the actions of the elite and the State.


The adaptive lattice prediction-error filter has been proposed as an alternative for a fixed moving-target indicator (MTI) filter presently used to detect a signal returned from a moving target in the presence of non-moving or slowly moving clutter as encountered in a radar environment. This paper examines the results from applying several forms of the lattice filter to actual data from an operational surveillance radar under a wide variety of environmental conditions. These results are compared with those obtained using the existing fixed filter for this radar (with the same input) and conclusions on their relative suitability are presented.


Among Negroes living in an SMSA outside the South in 1960, those born in the South had higher incomes and less unemployment than those born in the North with or without standardizing for differences in age, years of school, and a number of other variables. Recent migrants, defined as those living in an SMSA in 1960 but not in 1955, did have lower incomes than those who were in SMSAs in both years, although the differential is larger for whites than for Negroes. Several possible explanations for these results are discussed. Economists often look at migration as an investment and compare the income of migrants with that of people who remained behind. This study focuses on a different aspect of migration. It compares the migrants with those who were already at the destination point. Specifically, the study examines the migration of Negroes from the South to the northern cities and, The author is Associate Professor of Economics at the University of Notre Dame. * The statistical part of this study was performed at Rutgers University pursuant to a contract with the Office of Economic Opportunity.

The income and labor-force status of these migrants are compared with the corresponding values for Negroes who were already in the cities. By doing such a study, we can obtain at least a partial answer to the question, "How many of the problems facing northern (or urban) Negroes can be attributed directly to their migration from the South (or from rural areas)?" If we find that the migrants are much worse off than nonmigrants, then more resources probably should be allocated to special organizations in the cities to assist the newcomers. It might also be very important to improve the quality of schooling and counseling in the areas from which the migrants came. The results of this study indicate, however, that the migrants are likely to be better off than the nonmigrants, at least once an initial adjustment period is passed.l If the migrants are better off than the long-term urban residents, then efforts to improve the situation of northern Negroes should probably focus on the general issue of discrimination rather than on special programs to assist migrants. In addition, we should not be too optimistic that the position of northern Negroes will automatically improve as the migration slows down. This last statement must be qualified, however, since a decrease in the size of the migration might still improve the position of northern Negroes if the relative size of the Negro and white communities has an important effect on the opportunities available to Negroes. I. DATA AND THE MEASURES OF MIGRATION STATUS This study is based on data from the 1/1,000 sample of the 1960 Census. With these data we can look at both lifetime and recent migration. Lifetime migrants are Negroes who were born in the South but who are living in Standard Metropolitan Statistical Areas (SMSAs) outside the South in 1 Some earlier studies that have made somewhat similar comparisons, often as a side issue in connection with some other topic, are Karl E. and Alma F.

This study was conducted to investigate the interactions between metal ions and extracellular polymeric substances (EPS) with pH, contact time, compositions of EPS and concentration of EPS. The proteins were the dominated components in EPS of compositions. In particular, the optimal pH for the flocculation of EPS was approximately pH 5.0, except for Hg(II) which is stable in alkaline environments. The heavy removal efficiency of Ni and Al increased from 33 to 81% and 59 to 64%, respectively, when the contact time increased from 0.5 to 1.3 h. Furthermore, the EPS adsorption satisfactorily correlated Freundlich isotherm with the data of Al, Fe, Ni and Zn, with R2 ranging from 0.93 to 0.99, but poorly for Cu, with R2 ranging from 0.81 to 0.88. The results revealed that the flocculating capacity and metal removal ability of the EPS produced by Cloacibacterium normanense represent a good alternative as a bioflocculant and low‐cost adsorbent.


Within the framework of the project "Inputs for the delimitation of strategic ecosystems: paramos and wetlands", was carried out the characterization of bird life of the paramo complex "Los Picachos". This complex makes part of the more isolated high-Andean forest and paramo ecosystems in the southern of the eastern mountain range in Colombia. The high-mountain birdlife of the "serrania de los Picachos" it has maintained unexplored mainly for public order difficulties that made hard to get information belonging to these areas. This study is the first to achieve the exploration of the area in San Vicente del Caguan municipality, located between 2900 - 3100 m a.s.l. therefore, it represents the first findings about birdlife composition of high mountain of the mountain system. 97 species were identified, of which four are included in any category of danger and three are new records for south of eastern Andes. This allows the knowledge of geographic distribution of reported species in this part of the country.


Fingerprint feature extraction is a task that is solved using either a global or a local representation. State-of-the-art global approaches use heavy deep learning models to process the full fingerprint image at once, which makes the corresponding approach memory intensive. On the other hand, local approaches involve minutiae based patch extraction, multiple feature extraction steps and an expensive matching stage, which make the corresponding approach time intensive. However, both these approaches provide useful and sometimes exclusive insights for solving the problem. Using both approaches together for extracting fingerprint representations is semantically useful but quite inefficient. Our convolutional transformer based approach with an in-built minutiae extractor provides a time and memory efficient solution to extract a global as well as a local representation of the fingerprint. The use of these representations along with a smart matching process gives us state-of-the-art performance across multiple databases.

The feasibility of detecting stress distribution in magnetic materials by magnetic hysteresis and Barkhausen effect measurements has been evaluated using a newly developed magnetic imaging system. The system measured hysteresis loops and Barkhausen effect signals with the use of a surface sensor that was scanned over the material. The data were converted into a two‐dimensional image showing spatial variations of the magnetic properties from which mechanical conditions of the materials can be inferred. In this study a nickel plate machined into a shear‐beam load cell configuration was used. By applying a stress along the neutral axis, various stress patterns such as shear stress and stress concentration could be produced in different regions of the sample. The scanned images of magnetic properties such as coercivity and rms value of Barkhausen effect signal exhibited patterns similar to the stress distribution calculated using finite element model (FEM), in particular in the regions where a high stress lev...


The way in which project teams respond to problems and manage risks during IT project developments is affected by the organizational context. In particular, it is affected by the implicit 'contract' between the team and the organization. This contract is controlled through the adherence to formal methodologies and the use of organizational control system. This paper looks at risk management from the point of view of team behaviour, focusing on behavioural response to risks in terms of effort and risk aversion. Three case studies of project team behaviour are used to illustrate the types of risk management behaviour which may arise under different contracts between project team and organization.


Results. The correlation between the APHV and final height was very weak; however, the results of a multiple regression analysis showed that the final height of each prefecture can be accurately predicted based on the APHV and HPHV. This result showed that the earlier the APHV and higher the HPHV, the higher the final height. An earlier APHV reduced the height gain in the puberty component; however, this did not reduce the final height.


Recently, infra-red thermal images have drawn wide publicity for vehicle detection in traffic monitoring because of their resistances to insufficient light and hidden occasions. However, there are two significant challenges compared with vehicle detection in visible images. One is the insufficiency of the labelled infra-red thermal samples, and the other is less texture information. These two points lead to fewer parameters for the vehicle detection network in the infra-red thermal images. Therefore, to conquer these difficulties in infra-red thermal images, we construct a sparse neural network based vehicle detection method with sparse parameters (weights) and high generalization ability. Therein, to avoid over-fitting in the training stage, we eliminate some redundant parameters via constraints and on-line pruning. Finally, to verify the proposed vehicle detection method in infra-red thermal images, we introduce VIVID, VOT2019, and RGBT234 data sets. The vehicle detection results show that the proposed method presents superior results compared to several mainstream approaches.

Escalating demand for digital services has motivated the community to revisit the old ideas of peer-assisted models for resource trading. Cryptocurrencies have strengthened this trend by providing a fully distributed mechanism to compensate service provision. To promote practical deployment, in this article I present a generic framework for building decentralized service markets by utilizing these new technologies. I also discuss the security and efficiency challenges associated with the open-access work model of these markets along with some potential solutions. When obtaining digital services, usually we deal with traditional systems that are centrally managed. Most of the time, we resort to third party providers, or commercial companies, to obtain services like file storage, content distribution, computation outsourcing, and many others. Despite being effective and widely deployed, this centrally-managed paradigm introduces several trust, cost, and transparency issues. Companies may impose complex business relationships in which customers usually overprovision their needs in order to handle future peak demands. These companies also constrain customers with the service specifications that can be offered, such as geographic coverage and speed. Not to mention infrastructure dependencies where a system implementation is tied to the API provided by the underlying resource vendors. These issues raised many questions regarding the future of the Internet and its digital services; can we build flexible and equitable systems that allow anyone, from anywhere, to obtain or provide a service? Can we even deploy them in the form of decentralized resource markets in which computing services are exchanged for payments without intermediaries? And can we optimize these systems to be highly performant, and hence practical, without compromising security? The pursuit of answering these questions motivated the community to revisit the old ideas of peer-to-peer (P2P) based models in which anyone is allowed to join the system and serve others. In order to encourage collaborative work and compliance with the protocol, payments are provided in return, which creates a market for trading resources. This paradigm builds flexible systems, scales more easily with demand, and extends the network coverage since peers from anywhere can join. Furthermore, P2P-based models implement transparent and equitable ecosystems in which participants can negotiate service terms and price directly instead of having a few entities monopolizing the market. However, most of existing solutions for monetizing P2Pbased services introduce some form of centralization or trust. They either use centralized payment services, place trust in TABLE I: Examples of centrally-managed digital services and their counterparts of P2P-based ones.


Today world population is seven billion plus, and it will be nine billion by 2050. More than 53% are women who are experiencing diversified situation from born to death. Being women they faces challenges in treatment choice and hence women are neglected and isolated from performing social responsibility for the sake of so called vulnerable women health. In many developed countries woman's health, education, nutrition and economic power have indicated that women are still inferior to men. Women live in rural areas, are responsible for most of the domestic work without economical impact analysis that is done in rural areas. Women in cities can't advance further in manufacturing job. In this paper we discuss about violence against women (VAW) and also different health issues of women. We have designed and present a skeleton of a user friendly mobile application named Women Empowerment which will contain different laws related to VAW and also contains different health tips for women, which will help the rural as well as urban women. It includes emergency call system, which will be active by the victim women when they are in danger.


Abstract The analysis of overload conditions for each cell and the assembly operator is carried out based on micro modeling of operator movement patterns for the actual sequence of vehicles entering trim and final assembly. To achieve this, the system integrates the broadcast signal of the vehicle VIN number as the vehicles are released to final assembly with detailed information on the work elements from the direct labor management system and the workcell layout from the e-workcell system. This system gives advance warning to assembly line management and work group leaders of potential operator overload and/or interference, allowing time to dispatch auxiliary workers and eliminate potential line stoppages.

Scientific Initiation (SI) has been taking place in Brazilian universities since 1950, gaining greater support from the University Reform Law of 1968. Studies that seek to investigate SI programs in Brazilian Physical Education date back to 1999. In this context, this thesis aimed to investigate the role of Scientific Initiation in professional Physical Education training in Federal Public Universities in the state of Rio de Janeiro. The methodology is qualitative in nature, with the use of an inductive method presenting an exploratory bias. The data collection instruments consisted in semi-structured interviews (in person and on-line), observation and documentary sources. Bardin\2019s theory (2016) was used for the data analysis. The theoretical framework was based on Demo\2019s, Diniz-Pereira\2019s, Tardif\2019s and Latour and Woolgar\2019s ideas. The participant, former participant and SI program teacher samples belonged to higher education degree programs in Physical Education at UFRJ, UFRRJ and UFF. The results showed that the SI programs have been favoring the students to obtain a broader formation and deepening of the pertinent contents of the area, thus enabling a better academic performance, besides encouraging them to continue their formation by preparing them for enter the Stricto sensu postgraduate programs shortly after the end of the course, reducing the titling time as provided for in one of the CNPq objectives. Therefore, we conclude that, although the Higher education institutions have been striving to encourage research from the early periods of the courses, it is noticeable that there is a need for further expansion of SI programs, as well as an incentive policy with a larger number of offers scholarships so that the student can devote himself fully to the research.


The color mapping technique by means of EPMA (Electron Probe Microanalyzer) has been widely used effectively to measure the distribution of pulp and paper constituents such as fillers, Pigments, binder, Silicone, lignin and Xylan etc.The color mapping technique was initially introduced by transforming monochromatic X-ray images to color distribution maps through the color filters inserted in front of SEM CRT. But this manual and delicate technique was soon replaced by more precise and automatic procedures controlled by computer. Furthermore, the striking progress of computer brought the development of wide area state EPMA which was able to measure the distribution of elements on the area up to 8×8 cm2.In this paper, it was discribed how the EPMA color mapping techniques had been developed in the application to pulp and paper specimen.


This study aims to preserve spoken traditional art, especially folklore in Surakarta area and to use it as a character education media for young generation through cartoon character animation since folklore needs audiences' visualization. This study is an application research containing five stages, namely observation, collecting information and idea, elaboration for determining main idea through analysis, integration, abstraction, generalization, transmutation, synthesis to make the concept of artwork, realizing the concept in various art media, and finalization to complete the process in the form of artwork.

Data validity test employed data triangulation techniques in terms of data source and theory triangulations. The result of this study is that cartoon characters as media for delivering folklore through animation are disseminated into some educational institutions, governmental institutions and communities in Surakarta. These animation media of folklore in terms of cartoon character are supposed to be used as a media to introduce and to preserve folklore tradition to society, especially young generation in Surakarta.


modified the SOI into the GrowthEdge Interview to use as a develop mental intervention to promote self-authorship. Part 4 consists of one concluding chapter (chapter 15), where Baxter Magolda synthesizes theoretical and methodological issues raised in the previous chapters, presents excerpts from an interview with Robert Kegan, and points toward future directions in the study of selfauthorship. Kegan's commentary on research interview narratives, presented in chapters 1 and 2, serves as an illuminating means of sharing his current perspectives on selfauthorship and how it accounts for cultural and relational differences. Development and Assessment of Self-Authorship: Exploring the Concept Across Cultures brings together current, highly relevant scholarship and research on the developmental concept of self-authorship. Most importantly, the collective contributions in this book raise important questions and offer multiple perspectives on how culture and self-authorship interact and how we might best assess development of self-authorship. This book is of particular interest to scholars and researchers as it provides numerous directions for future conceptualization and research. It also is highly germane to student affairs practitioners and graduate preparation students. As we continue to develop services and programs for our students to support the development of self-authorship, it is critical that we understand what it looks like, how it evolves, how it is experienced by individuals from multiple cultures and contexts, and how we might measure it. This book makes major contributions toward the advancement of these understandings.


Currently container tracking in logistics mainly uses RF tags with the disadvantage that the container information is unclear to users so that it may pose docking problems. This paper proposes a visual tracking method based on the frame difference optimization algorithm.Unlike the fixed area RF tags,it takes the overall visual features of the container as the label feature,and conducts image feature extraction of the shipping container by means of image segmentation,which provides theoretical basis for visual container tracking. First take the key frames of container image features for background segregation,and record the characteristics,then use the similarity of the characteristics to fullfil logistics visual tracking. Experimental results show that using the method of visual tracking improves the tracking accuracy.
