The small data global well-posedness of the 3D incompressible Navier-Stokes equations in $\mathbb R^3$ with only one-directional dissipation remains an outstanding open problem. The dissipation in just one direction, say $\partial_1^2 u$ is simply insufficient in controlling the nonlinearity in the whole space $\mathbb R^3$. The beautiful work of Paicu and Zhang \cite{ZHANG1} solved the case when the spatial domain is bounded in the $x_1$-direction by observing a crucial Poincar\'{e} type inequality. Motivated by this Navier-Stokes open problem and by experimental observations on the stabilizing effects of background magnetic fields, this paper intends to understand the global well-posedness and stability of a special 3D magnetohydrodynamic (MHD) system near a background magnetic field. The spatial domain is $\mathbb R^3$ and the velocity in this MHD system obeys the 3D Navier-Stokes with only one-directional dissipation. With no Poincar\'{e} type inequality, this problem appears to be impossible. By discovering the mathematical mechanism of the experimentally observed stabilizing effect and introducing several innovative techniques to deal with the derivative loss difficulties, we are able to bound the Navier-Stokes nonlinearity and solve the desired global well-posedness and stability problem.

In the last decades, the problem of thermal transfer in heterogeneous media has been a subject of huge interest for a broad category of researchers: engineers, mathematicians, physicists (see [2] and [12]). Also, addressing contact problems for multiphase composites is important, since it is known that the macroscopic properties of a composite can be affected by the imperfect bonding between its constitutive components (for a review of the literature on imperfect interfaces in heterogeneous media, we refer to [13] and [15]). The main goal of this paper is to describe the macroscopic behavior of a system of coupled partial differential equations arising in the modeling of thermal transport in a two-component composite. We deal, at the microscale, with a periodic structure formed by two connected media with different thermal properties, separated by an imperfect interface. We assume that we have nonlinear sources acting in each media and that at the interface between the two constituents the flux is continuous, but the temperature field has a jump. We are interested in describing the asymptotic behavior, as the small parameter which characterizes the sizes of the two constituents tends to zero, of the temperature field in the periodic composite. The imperfect contact between the constituents generates a contact resistance and, depending on the magnitude of this resistance, a threshold phenomenon arises. So, depending on the rate exchange between the two phases, three important cases are considered and three


This cross-sectional and descriptive study aimed to describe the clinical profile of patients treated by removable prosthesis in the clinic of the Department of Odontology. The survey carried out using anamnesis and clinical examination of patients. The variables were about general and local nature. The statistical analysis was made by SPSS Version 16.0 with a risk error of 5%. The sample consisted of 51 patients including 80.4% of men. Their average age was 60.1 years. They were generally in good health (56.9%), with a sound supporting soft tissue (80.4%) and had bone resorption at the stage 3 of Atwood scale (74.5%). Full removable prosthesis was worn by 62.75% of the sample. The majority (54.9%) of the patients wore full removable prosthesis on the antagonist arch and 5.9% had a complete dental arch. The posterior edentulism accounted for 33.3%. Lesions of supporting soft and hard tissues observed are likely to promote prosthetic failure. In order to support the adaptation of their prosthesis, the execution of an adequate organization of rehabilitated patients recall procedures could constitute an appreciable alternative.


To the Editor: Thank you for offering the historical perspective on the early scientific case reports of angioedema. The historical preface to a scientific article adds perspective to the appreciation of this disorder and its management, and it enriches the experience for the reader. Osler's case report, published in 1888 in the American Journal of Medical Science, is recounted by Dr. Bellanti and Dr. Settipane in the September–October 2011 supplemental issue. The case that is discussed is one of "Mrs. H", a 24-year-old woman with recurrent swelling of the face and extremities, abdominal pain, nausea, and vomiting. The Editors state that "She (Mrs. H) reported that her deceased mother had the same symptoms." In his publication, Sir William Osler recorded in great detail the five-generation pedigree, as reported to him by "Mrs. H's" grandfather, "a venerable old patriarch of ninety-two." "Mrs. H," also known as Maggie, was the eighth of nine children born to George and his wife. Dr. Osler does not mention the identity or clinical status of "Mrs. H's" (Maggie's) mother. On the other hand, "Mrs. H's" grandfather related that Maggie's father, George, manifested swelling at age 20 years and "had many attacks." At the time of his death at age 60 years, it was believed that complications from Bright's disease were responsible. Although it can not be confirmed, it is possible that George developed chronic renal failure, probably caused by chronic glomerulonephritis, a potential complication of untreated hereditary angioedema. Although the Editors credit Osler for establishing the "classic features of an entity he named 'hereditary angio-neurotic edema,'" Osler himself acknowledges the previous detailed descriptions of Dr. E. Dinkelacker, who published his dissertation, On Acute Edema, while studying at the University of Kiel in 1882. Collaborating with Heinrich Quincke, these Kiel clinicians identified and established all of the elements mentioned by Dr. Osler in his 1888 paper. The investigators stated that "swellings occur most often at the extremities," edema may occur of the "laryngeal passage," with occasional "gastric and intestinal symptoms," and a hereditary pattern. Quincke's account, published in Monatschefte fur Praktische Dermatologie in 1882, was not as elaborate as that of his pupil Dinkelacker's dissertation or the cases described by Sir William Osler. German physician Paul Strübing first coined the term angioneurotic edema in 1885. It would not be until 74 years later, in 1959, that Lawrence Levy and Irwin Lepow successfully developed a C1 esterase inhibitor assay at their Case Western Reserve laboratory.


In recent years, machine learning has emerged as a powerful computational tool and novel problem-solving perspective for physics, offering new avenues for studying strongly interacting QCD matter properties under extreme conditions. This review article aims to provide an overview of the current state of this intersection of fields, focusing on the application of machine learning to theoretical studies in high energy nuclear physics. It covers diverse aspects, including heavy ion collisions, lattice field theory, and neutron stars, and discuss how machine learning can be used to explore and facilitate the physics goals of understanding QCD matter. The review also provides a commonality overview from a methodology perspective, from data-driven perspective to physics-driven perspective. We conclude by discussing the challenges and future prospects of machine learning applications in high energy nuclear physics, also underscoring the importance of incorporating physics priors into the purely data-driven learning toolbox. This review highlights the critical role of machine learning as a valuable computational paradigm for advancing physics exploration in high energy nuclear physics.


In connection with an attempt to utilize for crop production certain salty land on the Truckee-Carson Field Station, at Fallón, Nev., it has been necessary to make numerous determinations as to the limit of the salt content of the soil tolerated by crop plants. These determinations have shown that this limit of tolerance is not a fixed and definite point, but is instead extremely variable. Not only is it influenced by many factors, such as kind of soil, kind of salt, and kind of plant, but the same crop plant shows marked differences in tolerance at different periods of its growth. These facts make the problem of dealing efficiently with the reclamation of alkali land a very complex one. In the present instance the more abundant and deleterious salts are those of sodium. These sodium salts occur as carbonates, bicarbonates, chlorids, and sulphates, and the proportions of each in different parts of the field are extremely variable. This variability of the proportions in which these salts occur confused the results of the early attempts to determine the limits of tolerance for the different crope. In order to establish a basis from which to proceed with .the work, a series of pot cultures was carried on in which the soils were artificially Impregnated with solutions of the different salts. These experiments have served to show the limit of tolerance to each of the four salts of one crop, wheat, in the seedling stage. They have also brought out a point which has not generally been taken into account in similar experiments—that the limit of tolerance of plants is dependent not upon the quantity of salt added to the soil but upon the quantity which exists in the soil solution and which is recoverable from the soil by water digestion. It appears that the discrepancy between the amount of salt added to a soil and the amount which can be later recovered from it is sometimes very great. Different soils show different results in this respect; and some of the salts, particularly the carbonates and sulphates of sodium, are absorbed by the soil to a greater extent than sodium chlorid. Thus, if the limit of tolerance of a plant is given in terms of the quantity of salt which must be added to a soil to inhibit growth, this limit will be found


In this work, the MoS2 functionalized AlGaN/GaN high-electron mobility transistor (HEMT) was utilized for the first time to detect toxic mercury (Hg2+) ions under ultraviolet (UV) illumination. The AlGaN/GaN HEMT was fabricated on the sapphire substrate, and corresponding structural and electrical properties were investigated. Subsequently, the optimization of MoS2 concentration for device functionalization was carried out by performing sensing analysis of Hg2+ ions on three devices, and it was observed that the 20 mg/mL concentration of MoS2 is optimum for the detection of Hg2+ ions. Furthermore, the detection of Hg2+ ions was performed under UV exposure, where the developed sensor showed much-improved sensitivity of <inline-formula> <tex-math notation="LaTeX">$548.07~\mu \text{A}$ </tex-math></inline-formula>/ppb compared with normal light. The comparative analysis indicates the increase of three orders of magnitude in sensitivity under UV irradiation, and it is the highest sensitivity ever observed by the AlGaN/GaN HEMT sensor for Hg2+ ion detection. Moreover, the sensor also exhibits the limit of detection (LoD) of 6.14 parts per trillion (ppt) that is much lower than the World Health Organization (WHO) standard limit for Hg2+ ions in drinking water. Due to the photoexcitation process, the generation of electron–hole pairs provides more binding sites on the MoS2 surface, which results in the ultrasensitive detection of the Hg2+ ions at trace and ultratrace levels.

Home birth has attracted a great deal of attention of late, culminating in a meta-analysis to assess its risks for mother and baby. Mothers were estimated to be 2.6 times more likely to die and babies 3 times more likely to die from a planned home birth than from a planned hospital birth. The actual data on which these estimates were based demonstrate that meta-analysis can be developed into an art that suits whatever purpose its authors hope to achieve. Combining studies of home versus hospital, without differentiating what is inside them, where they are, and what is around them, is akin to producing a fruit salad with potatoes, pineapples, and celery.


: To achieve the goal of carbon peaking and carbon neutralization, we need to accelerate the construction of a clean, low-carbon, safe and efficient energy system, implement renewable energy substitution actions, and constantly increase the proportion of non fossil energy consumption. China's deserts, Gobi and desert areas cover a vast area, and solar energy resources are abundant. The regions that can be developed by technology account for more than 60% of the whole country. Give full play to the characteristics of desert, Gobi and desert areas that are rich in wind and solar energy resources, have good construction conditions, and are less affected by land use. In combination with the power grid and consumption and utilization conditions, comprehensively promote large-scale development and high-quality development of solar energy, it is an important measure to promote the clean, low-carbon, safe and efficient transformation of the energy structure. To vigorously develop photovoltaic projects in desert, Gobi and desert areas, we need to adhere to large-scale and intensive development, to adhere to multi energy complementary ecological integration development, demonstration and guidance, which can help strengthen the comprehensive utilization of land, solar energy resources and other resources, and also obtain significant ecological, economic and carbon reduction benefits. At the same time, developing photovoltaic bases in desert regions can also improve the supply capacity of renewable energy and increase the supply level of clean low-carbon energy.


In honor of the 100th birthday of E. Gräfenberg born on September 26, 1981 his biography is reported. This ingenious researcher suffered heavy blows by fate. During his residency in gynaecology in Kiel, Gräfenberg published important scientific papers (for instance on Gräfenbergstheory of malignant spread) and he studied the physiology of implantation with special reference of the tryptic enzymes of the membranes. As a specialist in gynaecology Gräfenberg developed a method to prevent implantation of the egg based on his studies of implantation. His intra-uterine ring was named Gräfenberg ring. It took until two years after the death of Gräfenberg until the modification of his method of family planning was accepted throughout the world in 1959.

Introduction: Many studies have reported that distress and related psychological health problems are higher among medical students compare to the general population. There have been no studies in Indonesia that have assess the stress level of medical students entering medical schools and longitudinally. The new admission system entering university has been implemented in the country since 2013 is through school matching program with the admission criteria based on high school performance as an addition to the existing admission examination test. The government gives full scholarship for students with low socio economic status. The programs affect on demographic characteristic of new students with substantial proportion of students from rural and low socioeconomic status. The students from rural and low socioeconomic status may feel isolated, which may lead to stress. Purpose: This study assesses baseline stress levels of students entering medical schools. Method: A cross sectional survey was conducted on 2013 intake of new medical students. We recruited 263 participants between September and October 2013 during the first two months of their university life. Level of distress was measured using an Indonesian version of the WHO General Health Questionnaire-12 (GHQ12). Results: Of 263 students, 52.2% were classified as being at risk of stress and 14.8% were classified as "stressed". There were no significant difference in level of stress between male and female students and those students with different socioeconomic status and geographic category (p>0.05). However, students from lower socioeconomic background and those from rural regions reported slightly higher levels of stress, though this difference was not significant (p>0.05). Students who obtained specific government scholarship due to low socioeconomic status were significantly higher of stress level (p<0.05). Conclusion: The study shows that new medical students had high levels of stress compare to the general public as measured by GHQ-12. Follow up study is planned to assess the effect of stress longitudinally in relation to academic performance.


Primary SCC of the breast is a very rare disease. Metastasis from elsewhere should be excluded first. The tumor is a very aggressive with poor prognosis. No standard treatment approaches are available. Managed by surgical excision followed by chemotherapy and radiotherapy.


The purpose of this research was to determine: 1)if the use of wet sieving (with its associated additional effort) to replace or supplement dry sieving is justified, based on the additional knowledge gained and problems alleviated, for the design and production monitoring of hot mixes; and 2) if the use of concrete sieves in place of hot-mix sieves for hot-mix design and production monitoring is justified based on the additional knowledge gained and the unified use of the same sieve sizes for both concrete and hot-mix testing. A minimum of 10 dry, wet and extraction sieve analyses were accomplished on 10 different produced hot-mixes for the SDHPT during the summer of 1982. In all, four hot-mixes were sampled from four weigh-batch plants, and six were sampled from four drum-dryer plants. The predominant type of hot-mix sampled was SDHPT Item 340 Type "D". Most of the aggregate combinations had limestone coarse aggregates and siliceous field sand fine aggregates, although one mixture consisted entirely of crushed gravel and another entirely of pit run iron ore.


There is no unique answer to the question of what an ongoing program costs in medical schools. The estimates of program costs generated by classical methods of cost accounting are unsatisfactory because such accounting cannot deal with the joint production or joint cost problem. Activity analysis models aim at calculating the impact of alternative combinations of school activities. As now practiced, activity analysis yields the incremental cost of an activity given all other school activities, that is, pure program costs. Such analysis is a potentially useful management tool. Input/output analysis is a special form of activity analysis in which some activities provide both final outputs and input into other activities. Following the introduction in Section I, this paper deals with cost analysis in section II and III. Section II discusses cost allocation studies that use the tools of classical cost accounting. Section III analyzes the use of linear regression as a tool for cost allocation, and Section IV examines activity analysis and optimization analysis.

This paper focuses on Korean non-contrastive adnominal fragment answers targeting an adnominal, that is, Left Branch, inside a certain NP within antecedent sentence. With regard to this type of fragment answers, Barros, Elliott, and Thomas(2014) argue that the answer is derived from a predicational source among three non-island repair-strategies (short source, cleft source, and predicational source) as an alternative to island repair approach. However, I will argue that when an adnominal fragment answer corresponds to wh-LB within a relative clause, the answer is derived from an amelioration effect-via- processing effect deletion at PF, and when the answer corresponds to wh-LB within a complex island NP, it is derived from amelioration effect-via-island effect deletion at PF.


Hong Kong is an enzootic area for Japanese encephalitis (JE) as shown by the continued seroconversion of pigs and birds in Hong Kong throughout the year. There are a large number of pig farms situated close to residential estates in the New Territories West area e.g. Yuen Long and Culex tritaeniorhynchus is found in considerable numbers near these farms. In general, Culex mosquitoes prefer feeding on pigs and birds rather than humans.

Two compounds, tricin and a related new flavolignan have been isolated from Aegilops ovata L. dispersal units. Evidence leading to assignment of structure of this new compound is presented together with 1H and 13C-NMR chemical shifts of related model compounds. These phenolics found together in the same plant species with a previously discovered lignan possessing activity as a germination inhibitor, raise the possibility of a new biogenetic link.


Studies have suggested that autistic individuals are as much as 30% more likely to receive a cancer diagnosis which may be associated with co-occurring IDD or birth defects. Following a diagnosis of cancer, outcomes have been documented to be significantly worse for autistic individuals. Autistic individuals experience numerous barriers to care across healthcare settings, including a lack of appropriate communication with providers, a lack of accommodating healthcare environments, lack of mental health support, and too few providers who are trained in working with individuals with autism or IDD. This leads to numerous negative health outcomes, including lower likelihood of having a regular source of care, lower satisfaction with healthcare, reduced screening utilization, delays in recognizing early symptoms of disease, higher ED utilization, and anxiety and stress associated with healthcare visits.
 We report on the results of a recent Medical Oncology provider survey conducted from 10/31/22 - 12/16/22 to evaluate for opportunities to address barriers to care facing individuals with autism and/or IDD. Of the 49 respondents comprised of physicians and nurse practitioners, 93.9% (46) noted receiving five or fewer hours of specific training or education regarding caring for populations with IDD. Additionally, providers cited the following barriers most commonly related to delivery care to patient with IDD: Lack of strategies to enhance communication on site (32, 65.3%), Inadequate time allotted for visits (28, 57.1%), Inadequate staff training and education related to this group (27, 55.1%), Limited resources to support vulnerable or lower socio-economic status populations (22, 44.9%), and Fragmentation of care (19, 38.8%).
 The Sidney Kimmel Cancer Center and the Jefferson Center for Autism & Neurodiversity have collaborated to develop a culturally competent care design aimed at understanding the needs of our neurodiverse population through a joint research effort. The results of our Medical Oncology provider survey identified the need for training of providers and staff to optimize the patient experience, creation of accessible cancer screenings, and the adoption of an environment that supports the sensory and communication abilities and needs of neurodivergent patients. Providers that adopt best practices in the care of autistic and/or IDD individuals have noted that patients and families report marked improvement in the rating of their patient experience in the visit. The desired product is care plans, appropriate medical settings, and trained providers that will meet the needs of this population and improve overall health outcomes.

Abstract Compressors operating in refrigeration systems, typically with built-in induction motors, represent an important energy demand. The applicability of standard methods for efficiency determination of induction motors is limited in this context by the constructive characteristics of these motors, such as the shared compressor frame and the inaccessibility of the shaft. The main contributions of this paper are to provide an overview of standard and alternative methods for efficiency testing of single and polyphase motors, according to technical standards and to the state of the art, and to offer guidelines for the method selection. The options cover dynamometer tests, loss segregation and equivalent circuit methods, some even applicable without direct access to the motor. Experimental application examples in single and three- phase motors are presented. Beyond the context of compressors, the discussion is relevant for inaccessible motors in general.


The magnetization process in nanostructured $(n\text{\ensuremath{-}})$ Fe and Co was investigated via small-angle neutron scattering (SANS). In a zero field, the magnetization exhibits correlations extending over several grains. In intermediate applied magnetic fields around $1\phantom{\rule{0.3em}{0ex}}\mathrm{kOe}$, $n\text{\ensuremath{-}}\mathrm{Fe}$ and $n\text{\ensuremath{-}}\mathrm{Co}$ samples with small grain sizes exhibit an anisotropic scattering profile with an unusual intensity enhancement for scattering vectors parallel to the field direction. Comparing the experimental data with a modeled granular microstructure containing magnetic domains of arbitrary size and orientation, we conclude that magnetic domains extending over several grains are tilted considerably out of the external field direction in intermediate fields. Since the domain size does not change significantly with the magnitude of the external field, we conclude that the magnetization process does not proceed via domain-wall motion. Together with theoretical arguments showing the existence of marginally stable domains within the random-anisotropy model, our SANS data suggests that the magnetization process proceeds by simultaneous reversal of a few adjacent domains, presumably in the form of small avalanches. This resembles the magnetization process predicted for random-field Ising magnets. Our theoretical analysis of SANS data is general and applies to other systems consisting of magnetic nanoclusters embedded in a nonmagnetic matrix.


men, their fancies or aversions, with all the humanities, great or small, which influence the development of science just as profoundly as they influence the spread of religion or the flowering of art. To illustrate the size of our field, it will suffice to compare it with others which are more familiar. It is essentially the whole of history plus the whole of science. The history of a great literature, such as the Greek, the French or the English, is a large field, but the history of science is as large a field as the history of all the literatures combined. It is indeed a history of all the literatures of the world, irrespective of language poetry and fiction being left out. The variety of possible courses on the history of science is due not only to the variety of points of view, but also to the immensity of the field. As it is impossible to deal with every part of the subject, no matter how you limited it to begin with, the teacher must necessarily make a selection of topics. That selection varies from man to man, and if the teacher be truly alive, it varies for himself from year to year. Out of the one hundred and forty lectures of my Harvard courses, it is probable that at least one hundred reoccur periodically (every two years), more or less modified, because some topics are too important to be left out. It would be impossible to eliminate, say, Hippocrates, Euclid, Newton or Pasteur. Other topics may vanish for a time. I love to introduce new topics,4 and this cannot be done without dropping others. A fresh study of Gassendi has given me recently a new appreciation of his importance; and when the cycle of my lectures brings me back to the seventeenth century in I 949, I shall devote far more attention to him than I have ever done before. Yet, if I speak longer of Gassendi, I shall have to neglect somebody else. Courses cannot be indefinitely extended. Each teacher will select the topics which he considers to be the most important, and also those which he feels more competent to deal with. If he has been trained as a chemist, he will select more chemical items; if he were an astronomer, he would prefer astronomical ones, and so on. That would be all right within limits. No teacher could teach the whole history of science, even if his cycle of lectures were ten years long, instead of being only two years long (as mine is). He will have done his duty, if his selection of topics is sufficiently varied and his treatment of each sufficiently thorough, to give the students an idea of the nature of science and of its essential humanity.

Autonomous underwater vehicles (AUV) recycling in an underwater environment is particularly challenging due to the continuous exploitation of marine resources. AUV recycling via visual technology is the primary method. However, the current visual technology is limited by harsh sea conditions and has problems, such as poor tracking and detection. To solve these problems, we propose a long-term target anti-interference tracking (LTAT) method, which integrates Siamese networks, You Only Look Once (YOLO) networks and online learning ideas. Meanwhile, we propose using the cubature Kalman filter (CKF) for optimization and prediction of the position. We constructed a launch and recovery system (LARS) tracking and capturing the AUV. The system consists of the following parts: First, images are acquired via binocular cameras. Next, the relative position between the AUV and the end of the LARS was estimated based on the pixel positions of the tracking AUV feature points and binocular camera data. Finally, using a discrete proportion integration differentiation (PID) method, the LARS is controlled to capture the moving AUV via a CKF-optimized position. To verify the feasibility of our proposed system, we used the robot operating system (ROS) platform and Gazebo software to simulate the system for experiments and visualization. The experiment demonstrates that in the tracking process when the AUV makes a sinusoidal motion with an amplitude of 0.2 m in the three-dimensional space and the relative distance between the AUV and LARS is no more than 1 m, the estimated position error of the AUV does not exceed 0.03 m. In the capturing process, the final capturing error is about 28 mm. Our results verify that our proposed system has high robustness and accuracy, providing the foundation for future AUV recycling research.

We have examined the microstructures of Cu-oxide superconducting thin films by cross-sectional transmission electron microscopic(TEM) observation. The films were prepared by reactive evaporation method with RHEED oscillations monitoring. The cross-sectional TEM observation provided informations on the growth mechanism of 1:2:3 compounds and on the epitaxial relations between the films and substrates. Sharp interfaces between the thin film of 123 compound and substrate were confirmed.


The generation of extremely short tunable laser pulses has opened the way for the study of fast transient phenomena such as exciton recombination in direct gap semiconductors. Using high spectral resolution resonant excitation measurements, combined with a novel time rejection technique, we have completed a comprehensive study of the nature and properties of a series of luminescence lines observed in the 1504-1511 meV region in GaAs grown by molecular beam epitaxy (MBE). These lines were found to be due to excitons bound to a series of axial defects having the electronic characteristics of double acceptors. Zeeman measurements were also performed in order to support this model. In another investigation, intense laser light excitation was used to create high concentrations of free carriers and excitons in various C semiconductors. When such high densities of excitons are achieved, a number of new effects can be observed, such as the formation of biexcitons (or excitonic molecules). The binding energies of these excitonic molecules were obtained experimentally for high-purity bulk ZnSe and GaAs, and found to be in good agreement with available theories. GaAs/GaAlAs quantum wells (QW) were also studied under high excitation intensities, and the results showed that biexcitons can also be created in such structures, but that care must be taken in order that they not be confused with extrinsic bound excitons. Photoluminescence (PL), PL excitation and time-resolved spectroscopy were also employed to interpret fine structure observed in GaAs/GaAlAs single QW grown by MBE under conditions of interrupted growth. This structure has been interpreted as originating within smooth regions in the QW layer differing in width by exactly one monolayer. Finally, a detailed experimental study of the influence of electric fields on exciton lifetimes in a GaAs/GaAlAs coupled double quantum well structure was undertaken. The decay time of the exciton peak was found to increase by over an order of magnitude as the electric field was increased. This increase is attributed to the change of the nature of the lowest energy exciton transition from spatially direct to


Strategic planning and appropriate development and management of water and sanitation services
can be strongly supported by accurate and accessible data. If adequately exploited, these data
might assist water managers with performance monitoring, benchmarking comparisons, policy
progress evaluation, resources allocation, and decision making. A variety of tools and techniques
are in place to collect such information. However, some methodological weaknesses arise when
developing an instrument for routine data collection, particularly at local level: (i) comparability
problems due to heterogeneity of
data and sector-re
lated indicators, (ii) in
adequate combination of
different information sources, and (iii) statistical validity of collected data.
The purpose of this study is to adopt an integrated water, sanitation and hygiene (WASH)
approach for data collection at community level in rural low income settings, as an attempt to
overcome previous shortcomings. The survey design takes the Water Point Mapping (WPM) as a
starting point to record all available water sources at a particular location, and this information is
then linked to data provided from a household-based survey. In order to demonstrate the
applicability of the method, a case study is presented at Tiraque Valley (Cochabamba, Bolivia).


Selective transmission of radiation through a two-dimensional array of subwavelength slits in an otherwise opaque thin metal film is presented at microwave frequencies. Individual slits are modified with the addition of perpendicular cuts, which interestingly and perhaps counterintuitively leads to resonant transmission when the incident radiation is polarized parallel to the slits. Finite element modeling of the structure shows the transmission of radiation polarized parallel to the slit direction to be a result of induced surface currents exciting a zeroth-order Fabry-Perot mode.


Background-Oral cyclophosphamide (OCP) in the treatment of frequently relapsing (FR) and steroid dependent (SD) idiopathic nephrotic syndrome (INS) poses problems of compliance, sideeffects and infections. Therefore,                      cyclophosphamide pulses given intravenously may provide an option that maintains remission with less-frequent side             effects.Aim- To assess the usefulness of Intravenous               Cyclophosphamide (IVCP) in FRNS and SDNS. Method- We retrospectively evaluated the usefulness of IVCP in children with FRNS and SDNS. Thirty children were included in this study of whom 17 were FRNS and 13 were SDNS. IVCP was administered in a dose of 500mgm2month for 6 months after achieving a steroid induced remission. During this period, patients were maintained on low dose oral steroids (5mgday). We retrospectively analyzed patients for compliance with therapy, remission rate, maintenance of remission,                       occurrence of relapse and side effects during this period and for an additional 6 months after withdrawal of                            cyclophosphamide. Results- At the end of 6 months treatment period 19 patients (63.3) were in remission. Number of              persistent remission at the end of one year was 15 (50).  Vomiting was seen in 4 patients (13.2). Two patients (6.6) developed pneumonitis. Leucopenia was seen in 3 patients (9.9) which were transient. No incidence of haemorrhagic cystitis. Notably treatment adherence was 100. No incidence of severe bone marrow depression and alopecia.                      Conclusion- IVCP has comparable efficacy with oral                cyclophosphamide therapy in SDNS and FRNS with less cumulative dose, fewer complications and good adherence.

THE POLITICAL ECONOMY OF DECENTRALIZATION IN BANGLADESH Since the 1980s, decentralization has been upheld as one of the major strategies of development in Third World countries. Donors led by the World Bank have pursued decentralization policies as a way of reducing the role of the state in welfare and service delivery. It has also been argued that decentralizing government to local level facilitates democratization in post-colonial states. Central to the concept of decentralization is participation as the inclusion of people in the decision-making and development processes. The thesis attempts to illustrate the decentralization policies in Bangladesh with greater attention to local government reforms initiated in the last two decades. In order to identify the dominant traits of the decentralization process, the study examines the sweeping political and economic changes occurring in the country in the period. In particular, the overthrow of the military regime in 1990 and the building of democratic structures at the national level was an encouraging prospect to transfer power and resources to the local areas. By focusing on two key elements of decentralization, namely autonomy and participation, the study undertakes the analyses of the composition, functions and their politico-administrative implications of the reforms undertaken by the various regimes. On the basis of the findings, the study argues that the transition to democracy did not bring any qualitative changes in decentralization efforts, particularly in terms of including rural population in the development process, and that the military government in power between 1982-90 effected the most far reaching changes in local government structure. While the authoritarian regime's policies reflected its increasing search for legitimacy and the need for creating a rural power base, reforms undertaken by both the "democratic" governments in the 1990s were characterized by the maintenance of the status quo or in some cases retrogressive steps.

A small business originates from an idea in some one's mind and grows from the development of that idea. Only after it has taken hold, been accepted and started to grow is it any more than the thinking of an individual. Governance therefore is entirely in the mind of the individual. The individual is the business. Governance reflects the personal beliefs and societal relationships of that individual.


This work presents a brief historical survey of the Church and State relationship from the introduction of Christianity into Russia in the tenth century until the beginning of the Russo-German War in 1941.


The transport and optical properties of semiconducting transition metal dichalcogenides around room temperature are dictated by electron–phonon scattering mechanisms within a complex, spin-textured and multi-valley electronic landscape. The relative positions of the valleys are critical, yet they are sensitive to external parameters and very difficult to determine directly. We propose a first-principles model as a function of valley positions to calculate carrier mobility and Kerr rotation angles, and apply it to MoS2, WS2, MoSe2, and WSe2. The model brings valuable insights, as well as quantitative predictions of macroscopic properties for a wide range of carrier density. The doping-dependent mobility displays a characteristic peak, the height depending on the position of the valleys. In parallel, the Kerr rotation signal is enhanced when same spin-valleys are aligned, and quenched when opposite spin-valleys are populated. We provide guidelines to optimize and correlate these quantities with respect to experimental parameters, as well as the theoretical support for in situ characterization of the valley positions.

Corvo is the smallest island of the Portuguese archipelago of the Azores and an unexplored territory, with one single village. Scarce studies have been conducted regarding its built heritage, and deep knowledge of the constructions is necessary for conservation actions to be carried out. This article presents the architectonic and constructive characterization of housing building features that compose Corvo village's historical center, focusing on its characteristics, dissonances, and conservation state. A case study regarding one housing building is presented. This research intends to contribute to a deeper knowledge of these buildings' identity, constituting the first step towards future rehabilitation processes that can improve the inhabitants' quality of life and simultaneously value the territory's singularity.


A mathematical model of the molecular weight distribution (MWD) based on a multilayer model and an improved intrinsic kinetics model was proposed to simulate the MWD of the gas-phase polymerization of butadiene with a heterogeneous catalyst. Intrinsic kinetics and heat and mass-transfer resistances based on the multilayer model of a polymeric particle were considered in the modeling of the MWD. The effects of the reaction conditions, catalyst particle size, mass-transfer resistance, deactivation of active sites, and transfer of the polymer chain on the molecular weight and MWD were simulated. The results show that the effects of the deactivation of active sites and transfer of the polymer chain on the average molecular weight are significant and that the effect of the catalyst particle size on the MWD is not significant. The simulation results of the molecular weight and MWD are compared with the experimental results. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 88: 88–103, 2003


The study aimed at investigating effects of growth-regulating substances salicylic acid (SA), methyl jasmonate (MeJA) and gibberellic acid (GA3) on accumulation of salvianolic acids, contents of non-structural carbohydrates and carbon/nitrogen ratios in seedlings and fruiting plants of Salvia miltiorrhiza by a pot experiment, further conclusion of which was demonstrated by comparing effects of sucrose, glucose and fructose of different medium concentrations on contents of salvianolic acids in cultures of S. miltiorrhiza hairy roots. The results exhibited an increasing trend in sucrose contents in both the seedlings and fruiting plants of S. miltiorrhiza for the SA treatment; but sucrose contents in both the MeJA-treated seedlings and fruiting plants and in the GA3-treated fruiting plants, together exhibited decreasing trends. Meanwhile, SA, MeJA and GA3 induced various changes in carbon/nitrogen ratios of the fruiting plants. However, contents of reducing sugar in both shoots and roots of the SA- or MeJA-treated different-aged plants and in roots of the GA3-treated fruiting plants, together with contents of rosmarinic acid in roots of the seedlings treated by the SA or MeJA, contents of rosmarinic acid and total amounts of salvianolic acids in roots of the fruiting plants treated by the SA, MeJA or GA3, were significantly increased. The culture experiment further demonstrated that glucose promoted production of rosmarinic acid and enhanced total amount of salvianolic acids in the S. miltiorrhiza hairy roots, whereas contents of salvianolic acids in the cultures did not exhibit positive correlation with medium concentrations of sucrose. This indicates that production and accumulation of salvianolic acids in roots of S. miltiorrhiza plants is induced by SA, MeJA and GA3, which does not correlate with carbon/nitrogen ratio and sucrose content in the plants. It is speculated that enhancement in glucose level of the plant accelerates production of salvianolic acids in the root.


On July 5, 2001, approximately 50,000 gallons of partially treated wastewater was accidentally discharged from the Mountain View wastewater-treatment plant in Howell County, Missouri, into nearby Jam Up Creek. The creek is a tributary of the Jacks Fork, a recreational stream administered by the National Park Service (NFS) as part of the Ozark National Scenic Riverways in southeastern Missouri (fig. 1). Jam Up Creek is located in a mature karst terrain and normally loses all surface flow about 0.5 to 1.0 river mile downstream from the wastewatertreatment plant. Historical dye-trace investigations conducted in 1972(Aley, 1975) and 1982 [unpublished data on file at the Missouri Department of Natural Resources, Geological Survey and Resources Assessment Division (MDNR-GSRAD)] indicate the existence of a subsurface hydraulic connection between the losing reach of Jam Up Creek and Big Spring on the Current River in the Ozark National Scenic Riverways (fig. 1; Imes and Kleeschulte, 1995). The time for dye to travel in the ground-water flow system through the karst terrain from Jam Up Creek to Big Spring (a distance of 38 miles) was estimated to be 35 to 40 days, which means that water transported the dye at a rate of about 0.95 to 1.1 mi/d (mile per day). The quantity


Searchable encryption (SE) allows a client to outsource a dataset to an untrusted server while enabling the server to answer keyword queries in a private manner. SE can be used as a building block to support more expressive private queries such as range/point and boolean queries, while providing formal security guarantees. To scale SE to big data using external memory, new schemes with small locality have been proposed, where locality is defined as the number of non-continuous reads that the server makes for each query. Previous space-efficient SE schemes achieve optimal locality by increasing the read efficiency-the number of additional memory locations (false positives) that the server reads per result item. This can hurt practical performance. In this work, we design, formally prove secure, and evaluate the first SE scheme with tunable locality and linear space. Our first scheme has optimal locality and outperforms existing approaches (that have a slightly different leakage profile) by up to 2.5 orders of magnitude in terms of read efficiency, for all practical database sizes. Another version of our construction with the same leakage as previous works can be tuned to have bounded locality, optimal read efficiency and up to 60x more efficient end-to-end search time. We demonstrate that our schemes work fast in in-memory as well, leading to search time savings of up to 1 order of magnitude when compared to the most practical in-memory SE schemes. Finally, our construction can be tuned to achieve trade-offs between space, read efficiency, locality, parallelism and communication overhead.


The reaction of the diosmacyclobutane 3 with butadiene gives as a kinetic product the 1,2 adduct Os[sub 2](CO)[sub 8][[mu]-CH[sub 2]CH(CH=CH[sub 2])] (4); the thermodynamic product is an allyl acyl dinuclear complex Os[sub 2](CO)[sub 8]([mu]-C(O)CH[sub 2]-[eta][sup 3]-CH[sub 2]CHCH[sub 2] ) (6), derived from 4 by CO insertion. Photolysis of Os[sub 8](CO)[sub 12] in the presence of butadiene gives 6, Os[sub 2](CO)[sub 7]([mu]-CH[sub 2]-[eta][sup 3]-CH[sub 2]CHCH[sub 2]) (7), and (butadiene)Os(CO)[sub 3] (8). The structure of 7 has been confirmed by X-ray crystallography: orthorhombic, space group P2[sub 1]2[sub 1]2[sub 1], a = 6.928(2) A b = 9.473(2) A, c = 20.683(4) A, V = 1357.4(6) A[sup 3], and Z = 4. The reaction of Na[sub 2][Os[sub 2](CO)[sub 8]] with 3,4-dichloro-1-butene or cis-1,4-dichloro-2-butene gave 7 as the principal product. Neither 4 nor 6 rearranged to 7 under thermal conditions, and attempts to carbonylate 7 to 4 or 6 failed at pressures of up to 120 psig.

This paper discusses the inspection and design of repairs to a pier 1118 km (695 miles) north of the Arctic Circle. The DeLong pier serves as the lifeline to resupplying and providing construction materials to the Thule Air Base in Thule, Greenland. The pier supports base operations and is the northernmost deep-water port in the world. The pier is constructed of four jack up barges originally conceived for service as oil exploration platforms in the Gulf of Mexico. The barges were towed to the site in 1951 as a temporary facility and have been in continual seasonal service to this date. Each barge is 76 m long by 15 m wide (250-ft long by 50-ft wide) and aligned end-to-end forming a 305 m (1000-ft) berth. Forty-eight (24 per side) 2 m (6-ft) diameter concrete filled steel caissons support the pier. The jack up barge type construction allowed the pier to be installed at the site within the limited weather window of the arctic environment. Early in the pier's life, many of the caissons began to exhibit cracks in their steel shells within the tide zone, presumably a result of ice expansion forces and steel that was unsuitable for extreme cold weather service. Numerous repairs have been carried out over the structure's life to address this problem. This paper provides an overview of the pier's history and arctic port operations and focuses on the recent rehabilitation project. These repair designs incorporated experience and knowledge gained from previous repairs and were detailed for a limited construction window of approximately two months.

To the Editor: We present the first reported case of a peripheral primitive neuroectodermal tumor (pPNET) in an adolescent male with Neurofibromatosis Type 1 (NF1). This case illustrates the need to be cognizant of rare tumors in adolescent patients with NF1, and the need for larger case series to understand the genetic mechanisms linking NF1 and pPNET. A healthy 14-year-old male with a negative family history presented with 6 months of left upper back/lower neck pain and swelling, and 1 month of progressive left arm weakness/paresthesia. Physical examination revealed a firm 5 × 6 cm mass in the posterior left lower neck associated with hyperesthesia and hypothesia in the left hand and arm, respectively, and reduced strength throughout the left upper extremity. Bilateral axillary freckling was noted with multiple 2–5 cm cafe-au-lait spots on the body. Computed tomography (CT) scan revealed extramedullary masses within the cervical spine with cord compression; MRI showed a left T2 hyperintense heterogeneous soft tissue mass from C2-T4 with multiple enhancing, enlarged foraminal nerve roots from C2–C7 extending into the epidural space. The bilateral axillary freckling and café au lait spots suggested previously undiagnosed NF1, with multiple plexiform neurofibromas therefore included in the differential diagnosis. Pathology showed a cellular tumor with sheets of small, poorly differentiated, malignant round cells within a variably myxoid background with geographic necrosis (Fig. 1A, 4×). Nuclei were round-to-oval with multiple fine nucleoli and minimal amphophilic cytoplasm with brisk mitoses (Fig. 1B, 40×). Immunohistochemical staining was positive for nuclear FL-1, nuclear WT-1, and membranous CD99 consistent with pPNET (Figs. 1C–1E, 40×). Even though EWSR1-FLI1 and EWSR1-ERG translocations were absent by RT-PCR, other variant translocations involving EWSR1 and other partner genes have been described in Ewing sarcomas.[1] Additionally, Ewing sarcomas lacking EWSR1 translocations with a Fused in Sarcoma (FUS)-associated translocation are known. [1] Despite negative RT-PCR results, the histopathologic and immunohistochemical features of the tumor were consistent with Ewing sarcoma/pPNET. Following initial radiotherapy and chemotherapy, repeat imaging showed disease progression, and the patient passed away 4 months after diagnosis. In addition to neurofibromas, patients with NF1 are at an increased risk of malignant peripheral nerve sheath tumors and pheochromocytomas, leukemia, rhabdomyosarcomas, and brain tumors.[2–4] The risk of malignant transformation is higher among individuals withNF1.[5] PNETs, rarely diagnosed in NF1, are malignant neural crest-derived tumors from remnants of the neuroectoderm and are divided into central nervous system PNET and pPNET. pPNETs are within the family of Ewing sarcoma tumors, but differ in their degree of neural differentiation.[6] Three previous reports described NF1 patients with pPNET;[7–9] however, our unique adolescent male highlights a category of patients (adolescents and young adults [AYA]) whose outcomes are influenced not only by treatment but also by "host" biology.[10] Further cases of AYA with NF1 and pPNET and other rare tumors are necessary to contribute to understand genetic mechanisms linking NF1 and pPNET.


A compact millimeter-wave dual-polarization antenna based on magneto-electric (ME) dipole is proposed. The antenna consists of four horizontal metallic patches placed on the upper dielectric substrate acting as electric dipole, and four vertical metallic posts and a cross-shaped slot serving as magnetic dipole. The two pairs of ME-dipoles fed by the cross-shaped slot etched on the top layer of SIW cavity. Unlike the traditional magnetic dipole, four rectangular metallic patches are symmetrical about the center and connected to each other, which achieves wide bandwidth and impedance matching. The results of simulation and measurement show that the antenna realizes impedance bandwidth of 16.8% (from 24 to 28.4GHz) for S11<-10dBi, and the isolation between two ports within the whole operation band is larger than 10dB. By controlling two different input ports, the horizontal and vertical ME-dipole can be excited separately to achieve dual-polarization.


Ordered rutile TiO2 nanorods grown on transparent electro-conductive F-doped SnO2-coated (FTO) glass substrates were prepared by a simple hydrothermal method using tetrabutyl titanate as the precursor and then calcined at various temperatures. The prepared SnO2/TiO2 composite film samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The photoelectrocatalytic (PEC) activity was evaluated by PEC degradation of methylene blue (MB) aqueous solutions under UV-LED light irradiation. The results showed that rutile TiO2 nanorods with diameters of ca. 300–700 nm and lengths of ca. 5 μm vertically grew on the FTO substrate. The resulting rutile TiO2 arrays exhibited excellent stability upon annealing in a temperature range of 300–500 °C. The sample calcined at 400 °C exhibited the highest PEC activity due to the combined effects of several factors including its one-dimensional morphology, high crystallinity, close contact between the TiO2 nanorods and SnO2 layers, SnO2/TiO2 n–n heterojunction and the applied external electrostatic field. The proposed enhanced PEC mechanism was further confirmed by the transient photocurrent response and electrochemical impedance spectroscopy (EIS) experiments.


Background The aim of this study was to compare the effect of addition of tramadol and magnesium sulfate as adjuvants to local anesthetics lidocaine 2% and bupivacaine 0.5% in sciatic nerve block classic posterior approach. Patients and methods A total of 90 ASA I or II patients, aged 17–50 years, scheduled for lower extremities surgeries under sciatic nerve block classic posterior approach were randomized into three equal groups. All groups received 20 ml of local anesthetics, which consisted of 10 ml bupivacaine 0.5% and 8 ml lidocaine 2% mixed with 2 ml saline in the control (C) group, 2 ml of 150 mg magnesium sulfate made in saline in the magnesium (M) group, and 2 ml of 100 mg tramadol in the tramadol (T) group. The onset and duration of both sensory and motor blocks, the intraoperative pain assessment by visual analogue scale, intraoperative analgesic requirements, postoperative pain by visual analogue scale, time to first analgesic request after surgery, postoperative diclofinac consumption, and adverse effects were assessed. Results The onsets of sensory and motor blocks were rapid in the M group, then C group, and lastly, T group. Much more time was needed for group T until sensory and motor blocks faded away followed by group M and then group C. There was a significant delay in the time of first analgesic request in groups M and T when compared with group C. There was a significant decrease in the total dose of diclofinac consumption in groups T and M in comparison with group C, where the patients consumed more analgesia. Conclusion Magnesium sulfate and tramadol as adjuncts to local anesthetics increase the duration of sensory and motor sciatic nerve block. The time for first rescue analgesia was longer in groups M and T, and they both showed decreased postoperative analgesic consumption.

Atmospheric Particulate Matter (PM) is considered one of the most important air pollutants in terms of its health impacts, environmental degradations and visibility. Particles size, their chemical composition and atmospheric level are important factors for determining their adverse health impacts. In this paper the main objective of this work was focus on PM10 and its bio-accumulations (microbial load) in Makkah during Hajj seasons 2016 (1437 AH). This study concluded that the concentration of respirable particles (PM10) and its water-soluble ions were much higher at site 2, site 1 than that at sites 3, 4 and 5 around Haram in Makkah. The secondary aerosols in terms of their concentrations can be arranged as follows: Cl-> Mg2+> NO3-> SO42-> NH4+> PO43-> Br-> Ca2+> F-. Furthermore, the concentrations recorded in this study were lower than the daily mean limitation of PM10 (340) in Saudi Arabia.In addition, Man is the main source of air microbial contamination surrounding Haram in Makkah. Fungi evidence of the lack of output from natural sources of pollution. Spotted Staphylococcus bacteria were at high rates in all sites and micro-organisms at the site 2. The source of microbial contamination in all sites was the same, while the source of fungi differs especially at the site 2. The natural resources were the most predominant at the site of 2 and 1, as compared to sites 3, 4 and 5.


Fuzhou basin is tectonically located in the eastern part of South China fold system, within the Fuding-Yunxiao Fault depression zone of East Fujian volcanic fault depression zone. It is a fault depression basin developed in the middle and late Quaternary, filled with marine, terrestrial and alternating marine-terrestrial facies sediments with complicated structures. Two test holes (SZK-1 and SZK-2) were drilled in the Gutian Street, Fuzhou City, with the purpose of setting up a standard section of Quaternary strata in Fuzhou basin. The SZK-1 test hole is 56.3m deep, in which the thickness of the Quaternary sediments is 51.1m. From the cores of this borehole, 25 samples were collected for thermoluminescent (TL) dating and 73 samples were collected for sporopollen analysis. The SZK-2 test hole is 53.2m deep, in which the thickness of the Quaternary sediments is 50.9m. From the cores of this test hole 18 samples were collected for TL dating. The distance of these two test holes is 113.5m. Basically, these two boreholes reveal the same features of deposition. The TL dating results of samples from these two test holes show good vertical time sequence and lateral correlation. The relative ages of sediments dated by sporopollen analysis in SZK-1 test hole show a good consistency with the ages dated by TL method. This study has led to some new insights about the sedimentary facies and succession, as well as the paleo-environment of the Fuzhou basin: (1) The sedimentation in Fuzhou basin initiated at middle Epipleistocene, at least at 54.3ka B.P., and terminated after 1ka B.P. (2) The ages of sediments from the two test holes can be assigned to Epipleistocene and Holocene. The Epipleistocene sediments can be subdivided into the sediments of middle and late Epipleistocene, i.e. 54.3ka B.P.~24 ka B.P. and 24 ka B.P.~ 11.3 ka B.P. Moreover, the Holocene sediments include the sediments of early, middle and late Holocene, i.e. 9ka B.P. to later than 1ka B.P. (3) The strata in the two test holes can be divided into three sections. The lower section corresponds to middle Epipleistocene, the middle section to late Epipleistocene, and the upper section to Holocene. (4) The sediments of middle Epipleistocene are composed of celadon gravel, coarse sand and clay, indicating a temperate and dry climate, while the sedimentary facies of the sediments can be assigned to lacustrine and lakeshore facies. The sediments of late Epipleistocene are composed of gray and yellow, coarse and medium sand, indicating a temperate and dry climate, while the sedimentary facies of the sediments can be assigned to fluvial facies. The early Holocene sediments consist of gray medium and coarse sand with a small amount of sludge, indicating a temperate and relatively wet climate, and littoral deposition environment. The middle Holocene sediments are composed of gray interbedded sludge and fine silt, indicating a warm and wet climate, and shallow-sea deposition environment. The late Holocene sediments consist of gray medium-coarse sand, sludge and clay, indicating a transition from littoral, neritic to lacustrine environment, and a warm and wet climate.


Line spectra in the radiated noise of marine vessels are the most visible signs,which can be detected,tracked and identified by enemy's passive sonar,and hence it is of great significance to reduce the line spectra for improving the acoustic stealth of marine vessels.Here,an anticontrol of chaos method based on chaotification was proposed for a vibration isolation system(VIS)of an on board machinery to produce the chaotic motion persistently.In this way,the line spectra in the radiated noise could be reduced effectively because the response spectrum of a chaotic system under harmonic excitations was a continuous and reduced one.Numerical simulations were carried out and the results verified the effectiveness of this method.


Contemporary approaches to political corruption have largely dispatched with moral theories, instead conceiving of corruption as an ill of a strictly political nature. Institutional analysis condemns it for its attack on our institutions, which are left unable to perform their primary functions, whereas relational analysis denounces the relational injustice of which corrupt public officials are guilty. I shall examine these two approaches, supplementing them with a contractualist perspective, according to which political corruption is morally unjustifiable for the same reasons that manipulation and promise-breaking are. In other words, political corruption consists in the violation of the expectations public officials have led us to develop regarding how they intend to exercise the power associated with their office.


Study about face recognition problem.The accuracy and efficiency of face recognition algorithm for traditional identification are low,is low.A new method of face recognition was proposed based on support vector machine.Firstly.The features of face characters were detected by Gabor filter and the principal component analysis feature extraction.Then the features were used to train support vector machine classifier.Finally,the face characters were classified by the support vector machine.The ORL face database was used to test the proposed method.Experimental results show that the recognition accuracy is above 98.0% and is by 5% higher than traditional algorithm.This method reduces not only the computational complexity and the training and recognition time,but also ensures the accuracy of real-time,improve recognition.This method in face recognition has been widely applied prospects.


Spherical distributed Bragg reflectors (SDBR) for near-infrared applications are elaborated via plasma-enhanced chemical-vapor deposition. They consist of the alternating quarter-wave layers of amorphous hydrogenized silicon (a-Si:H) and amorphous silicon oxide (a-SiO2) deposited onto a glass microsphere or quartz microsphere, doped by erbium ions with a diameter of 500 microns. The reflection and transmission spectra of the SDBR are measured at different points of its surface. A wide band with a high reflectance and a low transmittance – a stop-band is detected. It is demonstrated that for different radial directions from the center of the microspheres the stop-bands overlap, forming an omnidirectional stop-band. The influence of the omnidirectional stop-band on spontaneous emission of erbium ions (1.53 micron) from the quartz microsphere is studied. It is shown that the omnidirectional stop-band suppresses the intensity of spontaneous emission by more than an order of magnitude.


This paper aims at providing a general description for DIADORIM, a lexical database for Brazili an Portuguese. DIADORIM is said to successively merge two very different previous application-oriented dictionaries, increasing their user-friendliness, the reusabil ity of their entries and their capabilit y of incorporating new features. Besides improving the structure of the previous databases, DIADORIM also preserves their performance and functionality, as indicated in the real use and simulation tests carried out during its evaluation.


Road fatalities remain a major public health concern as over 1.3 million people across the world die in road accidents annually, and another 20-50 million sustain injuries. Malawi, with vehicle ownership about 437,416, has not been an exception to this, with reported fatality rates of 35 crash deaths per 100,000 population, possibly due to limited understanding of factors that contribute to such high road fatality rates. This may have resulted in implementing inappropriate and ineffective mitigation measures. Thus, the overall objective of this study was to investigate the availability, including their functionality and usage of seatbelts in motor vehicles, which could possibly be one of the major factors for increase in road fatalities. To establish the rates of availability,
 ncluding their functionality and usage of seatbelts in motor vehicles, primary data through survey for a sample of 1,200 vehicles were investigated. The independent
 ariables of data were cross tabulated with the dependent variables to establish these rates. Chi-square test was also performed to establish the significance of associations between the cross tabulated variables. The analysis found that Malawi's drivers and
 assengers poorly comply with seatbelt laws. The overall seatbelt usage rate was 35.8%. In this regard, where over 90% of motor vehicles in Malawi have functional seatbelts, poor enforcement of existing seatbelt laws and awareness on the dangers of not using
 eatbelts could account for the low usage.

… The individual who has insurance which covers all costs demands medical care as though it had a zero price, but when he purchases insurance, he must take account of the positive cost of that care, as "translated" to him through the actuarially necessary premium. Hence, he may well not wish to purchase such insurance at the premium his behavior as a purchaser of insurance and as a demander of medical care under insurance makes necessary. The presence of a "prisoners' dilemma" motivation makes this inconsistency inevitable. Each individual may well recognize that "excess" use of medical care makes the premium he must pay rise. No individual will be motivated to restrain his own use, however, since the incremental benefit to him for excess use is great, while the additional cost of his use is largely spread over other insurance holders, and so he bears only a tiny fraction of the cost of his use. It would be better for all insurance beneficiaries to restrain their use, but such a result is not forthcoming because the strategy of "restrain use" is dominated by that of "use excess care." It has been recognized in the insurance literature that medical insurance, by lowering the marginal cost of care to the individual, may increase usage; this characteristic has been termed "moral hazard." Moral hazard is defined as "the intangible loss-producing propensities of the individual assured" [Dickerson, 1963, p. 463].

Digital Access to the Legal Files of those tried for Nazi collaboration in the Netherlands: Possibilities and Impossibilities

 This article reflects on the findings of a pilot project called Triado that digitized a sample of the 4km of legal files created by the Special Jurisdiction for investigating Dutch Nazi collaboration (CABR) in the years after the Second World War. We show that large scale digitization may help to analyze complex historical sources in new ways, thus deepening our understanding of the consequences of war and genocide. However, this can be achieved only if all specialists involved develop ways to deal with ambiguity in the sources: instead of disambiguation we need mixed approaches that allow for data to have multiple meanings and for interpretation of meaning to change over time. This article offers suggestions and gives a brief overview of some of the possibilities for researchers and lay users of digitized historical sources.


Objective: To study the optimal condition for porcine oocyte maturation in vitro and supply abundant high quality MⅡ porcine oocyte for producing transgenic cloned pig by somatic nuclear transfer. Methods:Effects of dose and combination of hormones, PFF, cysteine and granular cell on porcine oocyte maturation in vitro and developmental competence were studied by technology of porcine oocyte maturation in vitro. Results and Conclusion: The maturation rate in medium of 15 U/ml PMSG+20 U/ml hCG was(70.0±3.30)%, higher than that in media of 15 U/ml FSH+30 U/ml LH and 10 U/ml PMSG+10 U/ml hCG〔(45.6±5.10)% and (60.0±3.30)% ,respectively〕.The medium with hormone could promote cleavage of oocytes. The maturation rate in medium of 15% PFF was (86.7±3.35)%, higher than that in media of 5%,10% and 15% PFF group〔(73.3±3.35)%,(71.2±5.08)% and (70.0±6.70)%, respectively)〕.The cleavage was promoted in the medium with PFF. The cleavage of oocytes after parthenogenetic activation was higher than controls, although there was no difference in maturation rate.

As we all know, "summer fishing moratorium" is an internationally recognized management measure of fishery, which can protect stock of fish and promote the balance of marine ecology. In this paper, "intermittent control" is used to simulate this management strategy, which is the first attempt in theoretical analysis and the intermittence fits perfectly the moratorium. As an application, a stochastic two-prey one-predator Lotka-Volterra model with intermittent capture is considered. Modeling ideas and analytical skills in this paper can also be used to other stochastic models. In order to deal with intermittent capture in stochastic model, a new time-averaged objective function is proposed. Besides, the corresponding optimal harvesting strategies are obtained by using the equivalent method (equivalency between time-average and expectation). Theoretical results show that intermittent capture can affect the optimal harvesting effort, but it cannot change the corresponding optimal time-averaged yield, which are accord with observations. Finally, the results are illustrated by practical examples of marine fisheries and numerical simulations.


ABSTRACT
 Assays of chitinase, cellulase, and amylase activities in the crystalline styles of selected fast- and slow-growing families of the mussel Perna canaliculus were carried out on 2 occasions over 6 mo, during which time the shellfish grew in a normal mussel cultivation situation. The data did not support the hypothesis that differences in growth rate by these families could be related to differences in the expression of digestive enzymes in the styles, leading to improved nutritional efficiency by faster growing families. On the contrary, the styles of faster growing families in general exhibited lower rates of enzyme activity. Differences in enzyme activities between families appeared to be related to the size of the individuals rather than their genetic heritage. The crystalline styles of larger, more mature shellfish contained less moisture and less soluble protein, and the lower rates of enzyme activity in larger individuals may be indicative of a reallocation of style protein synthesis toward higher levels of insoluble structural proteins.


The automatic detection of foreground (FG) objects in videos is a demanding area of computer vision, with essential applications in video-based traffic analysis and surveillance. New solutions have attempted exploiting deep neural network (DNN) for this purpose. In DNN, learning agents, i.e., features for video FG object segmentation is nontrivial, unlike image segmentation. It is a temporally processed decision-making problem, where the agents involved are the spatial and temporal correlations of the FG objects and the background (BG) of the scene. To handle this and to overcome the conventional DL models' poor delineation at the borders of FG regions due to fixed-view receptive filed-based learning, this work introduces a Multi-view Receptive Field Encoder-Decoder Convolutional Neural Network called MvRF-CNN. The main contribution of the model is harnessing multiple views of convolutional (conv) kernels with residual feature fusions at early, mid and late stages in an encoder-decoder (EnDec) architecture. It enhances the ability of the model to learn condition-invariant agents resulting in highly delineated FG masks when compared to the existing approaches from heuristic- to DL-based techniques. The model is trained with sequence-specific labeled samples to predict scene-specific pixel-level labels of FG objects in near static scenes with a minute dynamism. The experimental study on 37 video sequences from traffic and surveillance scenarios that include complex environments, viz. dynamic background, camera jittery, intermittent object motion, scenes with cast shadows, night videos, and lousy weather proves the effectiveness of the model. The study covers two input configurations: a 3-channel (RGB) single frame and a 3-channel double-frame with a BG such that two consecutive grayscale frames stacked with a prior BG model. The ablation investigations are also conducted to show the importance of transfer learning (TL) and mid-fusion approaches for enhancing the segmentation performance and the model's robustness on failure modes: when there is lack of manually annotated hard ground truths (HGT) and testing the model under non-scene-specific videos. In overall, the model achieves a figure-of-merit of ${95\%}$ and 42 $FPS$ of mean average performance.


The Waste Water of paper industries normally contains suspended solid particles which have specific gravity lower than specific gravity of water, therefore in the waste water treatment needs flotation treatment to remove the suspended solid Research on treatment of waste water of paper industry (pH= 7.35, TOC = 331,7 mg/land SS= 796 mgll) has been done by using coagulation followed by flotation. The Waste Water of paper industry is treated by using Fe Cl3, 6H20 and Al2(S04)J 18H20 as a coagulant, NaOH as neutralizing agent, and three kinds of polymer (cationic, non ionic and anionic) as a flocculant . The optimum dosage for the best result is Al2(S04)J l8H20 300 mg/I, NaOH 100 mg/l, and anionic polymer A-2022 5 mg/l. The final result is decreasing of TOC value from 331, 7 mg/l to 38,4 mg/l and SS from 796 mg/l to 5 mg

The bottom-charmed meson spectrum is studied in this work via an effective version of the Coulomb gauge QCD Hamiltonian. The Tamm-Dancoff approximation is employed to estimate the energies of the low-lying and radial-excited $B_c$ states with quantum numbers $J^P = 0^{-}, 0^{+}, 1^{-}, 1^{+}, 2^{+}, 2^{-}$. In particular, we analyze the effects of incorporating an effective transverse hyperfine interaction and spin mixing. The Regge trajectories and hyperfine splitting of both $S$- and $P$-wave states are also examined. The numerical results are compared with available experimental data and theoretical predictions of other models.

The Dirac equation for charged and neutral fermions with anomalous magnetic moments is solved in a uniform magnetic field. We find the relativistic wave functions and energy spectra. In the non-relativistic limit the wave functions and energy spectra of charged fermions agree with the known solutions of the Schroedinger equation.


Einstein's weak equivalence principle (EEP) can be tested through the arrival time delay between photons with different frequencies. Assuming that the arrival time delay is solely caused by the gravitational potential of the Milky Way, we show that a "nano-shot" giant pulse with a time delay between energies corrected for all known effects, e.g. $\Delta t<0.4~\rm{ns}$, from the Crab pulsar poses a new upper limit on the deviation from EEP, i.e. $\Delta\gamma < (0.6-1.8)\times 10^{-15}$. This result provides the hitherto most stringent constraint on the EEP, improving by at least 2 to 3 orders of magnitude from the previous results based on fast radio bursts.


The nutritional status of a pregnant woman can be seen from several things, including the Body Mass Index and the diameter of the upper arm circumference. Urine glucose describes the state of glucose in urine. The well-being of a baby in the womb can be measured through the estimated fetal weight according to the gestational age. This study aims to determine the relationship between nutritional status and urine glucose on the estimated fetal weight. Using a cross sectional research method with a sample of 30 respondents taken at the Prima Husada Hospital Sidoarjo during May-July 2020. The results of the analysis of body mass index and estimated fetal weight obtained p value = 0.337 (> 0.05), on the upper arm circumference and estimates fetal weight obtained p value = 0.03 (<0.05) and in urine glucose and fetal weight estimates obtained p value = 0.19 (> 0.05). In conclusion, there is no relationship between body mass index and estimated fetal weight. There is a relationship between the circumference of the upper arm and the estimated fetal weight. And there is no relationship between urine glucose and estimated fetal weight. Women must prepare physically from before pregnancy to optimize future baby growth. Midwives must also regularly provide health education to improve women's health status


A 34 year old female presented with fever, diarrhoea, confusion, and a decline in mobility, having recently tested positive for COVID-19. Her medical history included patent foramen ovale, primary ovarian failure and leukoencephalopathy which had been investigated in her 20s leading to a clinical diagnosis of Vanishing White Matter disease (VWM). On admission she deteriorated rapidly with decreased GCS requiring frequent critical care review. MRI demonstrated mild progression of the cerebral atrophy and slight increase in the "cystic" changes in the white matter. Lumbar puncture was unremarkable. EEG demonstrated widespread cerebral dysfunction with frontotemporal emphasis but without seizure activity. She was managed with supportive care recovering to her baseline function within days. VWM is a leukodystrophy caused by recessive mutations in eukaryotic initiation factor 2B (eIF2b) complex. Adult onset presentations have been described which have a slowly progressive course. Patients with VWM are known to rapidly decline with fever, and mild head injury occasionally resulting in coma. Our case high- lights the potentially devastating effects of a neurotropic virus such as COVID-19 in VWM, and the need to consider rare genetic disorders in adult patients presenting with extensive white matter abnormalities on MRI and premature ovarian failure. sara firstname.lastname@example.com|ABN Bursary 62


In controlling tomato gray mold (caused by Botrytis cinerea Pers.) in the field, pyrimethamil 40% SC at a 1:800 dilution provided 90.1 and 85.2% protection of leaves and fruits, respectively. These results were significantly better than the protection provided by procymidone 50% WP at a 1:1000 dilution. At dilutions of 800 to 1200, pyrimethamil provided 85 to 90% protection with good crop safety.
