A simplified method for the calculation of dynamic characteristics of initially stressed antisymmetric cross-ply laminated shells is presented in this paper using the natural frequencies under unloading state. The equation of motion of laminated shell with two opposite edges simply supported is investigated on the basis of Rayleigh-Ritz method and Mindlin shell theory with effect of the curvature term. The relationships of the non-dimensional natural frequencies with initial stresses the coeffcients of critical buckling and the boundaries of te dynamic principal instability region can be characterized by the non-dimensional natureal frequencies under unloading state. Numerical examples are presented t verify the simplified equations and to illustrate potential applications of the analysis.

Adopting this new foundation treatment method the technological benefit and economical benefit are both acquired, and good treatment effect is verified by checking.


In order to derive system-based methods to control dynamic behavior of biological systems of interest for future gene-based intervention therapeutics, two basic categories of intervention strategies have been studied based on the Markov chain theory and Markov decision processes: Structural intervention by function perturbation and external control based on state perturbation. The chapter reviews the existing network analysis and control methods in these two categories and discusses their extensions for more robust and clinically relevant intervention strategies considering collateral damages from intervention.


Herein, TiO2 nanotubes (T-NTs) arrays were subjected to two types of treatment followed by a simple metal deposition technique to significantly enhance the performances of T-NTs based electrochemical sensing of dopamine. The first type of treatment was done by soaking T-NTs in sodium hydroxide solution for an optimal time to enhance the conductivity and charge carrier density. The second type of treatment employed was laser irradiation, which induces crystallinity disorder and forms rutile TiO2, promoting active analyte adsorption sites. Afterward, silver (Ag) was electro-deposited on the T-NTs as a dopamine sensing catalyst to form T-NTs/Ag nanohybrids. The dual-treated T-NTs based sensor showed 3-fold enhancement in sensitivity (from 8.2 μA mM−1 cm−2 to 32 μA mM−1 cm−2), reduced charge transfer resistance (from 38 × 10–6 Ω to 0.7 × 10–6 Ω), above 2 order higher donor charge density (from 3.58 × 1018 cm−3 to 1.41 × 1021 cm−3), and reduced limit of detection (from 32.3 μM to 2.8 μM) in comparison to plain T-NTs based sensor. In addition, the sensitivity reported here is significantly higher than most of the previously reported TiO2 based dopamine sensors. Perspective-wise, the dual treatment approach is a promising technique and is highly desirable for enhancing the performances of T-NTs and other nanomaterial based electrochemical sensors.


The population of Mexico increased from 20 million in the 1940s to 50 million in 1970. Early in the 1970s Mexican leaders realized that the country had developed and advanced economy and a population with new and more difficult needs and aspirations that would require new policies and strattegies to satisfy. Demographic projections made in the 1960s that showed the momentum built into the current population trends by the annual rate of increase of 3% since the 1950s and the realization that despite several decades of growth in national wealth large numbers of people still lived a marginal existence were behind the official change in attitude. Faced with an economic and social system showing signs of stress and a probable population of 130-135 million by the year 2000 Mexicos rulers looked for reforms that would bring economic and demographic trends into balance. The current national population policy stems from the New General Population Law of 1973 which renounced all pronatalist attitudes and called for introduction of family planning programs. The previous ban on advertising and selling contraceptives was removed and a general shift in attitudes followed announcement of the new government policy. The National Population Council was created to carry out programs under the national population policy. It drew up targets--2.5% population growth by 1982 and 1% by 2000. The targets were to be achieved by vigorous implementation of family planning programs and activities integrated with other social and public health programs especially maternal and child health. Surveys indicate that the average number of children/woman of childbearing age declined from 6.5 in the early 1970s to 4.5 10 years later. The change in fertility has not been uniform in Mexican society but some change has been felt everywhere. The rate of growth in 1980 was estimated at about 2.7% and it is now projected that the population will be about 100 million in 2000. 1 of the greastest challenges in the next decade will be the rapid growth of the labor force from about 20 million in 1980 to 35 or 40 million or more by the year 2000. The world recession is affecting Mexicos economy and is threatening its demographic adjustment. Means of economic and social development with growth and equity which take the demographic dimension into account must be explored.


The invention discloses a long-time light-emitting detection circuit which is used for detecting the long-time light-emitting state of an ONU according to a light-emitting state signal of the ONU. The long-time light-emitting detection circuit starts to collect the light-emitting state signal on each rising edge or each falling edge of a clock signal, the collected light-emitting state signal serves as a long-time light-emitting signal. Within the time range from each rising edge or each falling edge to the next rising edge or the next falling edge relative to each rising edge or each falling edge in the clock signal, when the level of the light-emitting state signal jumps, the level, existing when the level of the light-emitting state signal jumps, of the light-emitting state signal is used by the long-time light-emitting detection circuit for filling the long-time light-emitting signal within the time range from the moment when the level of the light-emitting state signal jumps to the next rising edge or the next falling edge of the clock signal. The digital sequence circuit mode is used for judging long-time light-emitting by the long-time light-emitting detection circuit. The long-time light-emitting detection circuit further avoids generation of wrong logics in a sequence circuit through and operation and the like.


ABSTRACT Students, academics and university administrators are increasingly using and producing digital platforms, including social media. This paper focuses on LinkedIn to start tackling the question of the effects on higher education as a sector, its actors and the established social practices. It argues that LinkedIn moves beyond the passivity of advertising to its users towards actively structuring digital labour markets, in which it strategically includes universities and its constituents. By introducing the term 'qualification altmetrics', the paper suggests that LinkedIn is building a global marketplace for skills to run in parallel to, or instead of university degrees. Qualification altmetrics might challenge the established practices of knowledge production and valuation.


Introduction: Biomarkers that can be used to identify patient subgroups with shared pathophysiology and/or that can be used as pharmacodynamic readouts of disease state are valuable assets for successful clinical trial design. In translational research for brain diseases, extracellular vesicles (EVs) have become a high-priority target for biomarker discovery because of their ubiquity in peripheral biofluids and potential to indicate brain state. Materials and methods: Here, we applied unbiased quantitative proteomics of EVs isolated from DYT-TOR1A knockin mouse embryonic fibroblasts and littermate controls to discover candidates for protein biomarkers. We further examined the response of genotype perturbations to drug treatment conditions to determine their pharmacodynamic properties. Results: We found that many DYT-TOR1A MEF EV differences were significantly corrected by ritonavir, a drug recently shown to correct DYT-TOR1A phenotypes in cell and mouse disease models. We also used tool compounds to explore the effect of the integrated stress response (ISR), which regulates protein synthesis and is implicated in dystonia pathogenesis. Integrated stress response inhibition in WT cells partially phenocopied the effects of DYT-TOR1A on EV proteome composition, and ISR potentiation in DYT-TOR1A caused changes that paralleled ritonavir treatment. Conclusion: These results collectively show that DYT-TOR1A genotype alters EV protein composition, and these changes can be dynamically modulated by a candidate therapeutic drug and ISR activity state. These mouse model findings provide proof-of-concept that EVs may be a useful source of biomarkers in human populations and further suggest specific homologs to evaluate in cross-species validation.

The study focused on determination of thermal behavior of waste-derived fuel under air and air-free conditions. Thermochemical processes are commonly used as waste management options in order to produce energy and minimize the amount of solid wastes. Since the population all over the world is rising, the general concern becomes to find alternative ways to manage all types of waste in an economic manner as increasing the process efficiencies. Treatment sludge, with its complex matrix, needs special attention to prevent environment from its adverse effects in case any contamination. The main idea in this paper is to increase energy content of waste-derived fuel by mixing solid and liquid wastes. As a solid waste, treatment sludge (raw sludge) from a domestic wastewater treatment facility was selected. Waste cooking oil (used oil) was used as liquid form to increase calorific value of waste mixture before gasification experiments. Elemental carbon content of raw sludge increased from 27% (mass) to 32% and 37% after preparing a proportion of 1/5 oil/sludge and 2/5 oil/sludge, respectively. Thermochemical behavior of those mixtures were analyzed by Thermal Gravimetric Analysis (TGA) technique. Optimum proportion for gasification of waste-derived fuel was determined as 40%, which also prevents the mixture to behave like a liquid due to viscosity. Syngas had a calorific value of approximately  2700 kcal/m 3 .


Presented a high precise temperature measurement and control system which consists of STC89C51 RC as kernel,temperature detecting input and filtering circuit,and the triggering pulse output circuit of thyristors.Because the temperature-resistance characteristic curve of a platinum resistor is nonlinear,special current type temperature detecting circuit,digital filter,and the scaling function derived by use of a curve fitting scheme are used to compensate the nonlinear measurement error of the platinum resistor Pt100 in order to guarantee the temperature measurement precision.Meanwhile,the integration separation PID control algorithm and the optimization method of control parameters are adopted to improve the temperature control precision.Furthermore,the developed system is tested and used to measure and control the water temperature repeatedly in the laboratory.The experimental results show that the temperature measurement and control method are feasible,and the temperature measurement and control precision of the system come up to ±0.04 ℃ and ±0.5 ℃ respectively.


The objective of this work was to identify the social representations of citizenship of Brazilian senators in the scope of the debate on social policy in Brazil, during the years of 2003 up to 2006, first government of president Lula. It was developed under the bases of the Theory of Social Representations, by Serge Moscovici,
using for empirical analysis the speeches emitted by senators in the plenary assembly of the Federal Senate, according to indexation in the System of Information of National Congress. The research claimed to contemplate historical
aspects of the social protection system and the political system in Brazil in order to find the nexuses between conceptions of citizenship gifts in the political culture, the agenda of social politics, and the paper of parliamentarians. The ideas of citizenship found throughout the revision of literature had been categorized into
seven tipes to serve for indicative basis of the structure and process of formation of the social representation in the speeches. They had been articulated to the results of the data processing throughout the ALCESTE method. Thus, the
research found the field of the social representation of citizenship between the
senators, in which the unifying element is the global conscience, used as reference for the debate on social problems and politics in the country. This element is linked to the notion of global citizenship, conception introduced under the influences of globalization and the international organizations. But, the
representational field is also formed by new elements anchored in old conceptions of citizenship and national identity. Solidarity is an element that exerts significant function in the structure of the representation, conecting the State, civil society, private initiative and excluded or vulnerable groups. Thus, the function of the State is mainly to foment the partnership between these actors and moralization of the groups behaviors, stimulating solidarity as strategy of social development. This dynamics confuses the visualization of social conflicts into Brazilian society, as well as it overshadows the debate on racial inaquality and the proposal of Basic Income of Citizenship. This proposal appears as peripheral element in the
representation, linked to the Bolsa-familia Program (program of income transference). This program was very supported by the subjects and has
characteristics very next to the conception of global conscience, despite anchored in old ideas by the origins of our system of social protection. Thus, the social representation of citizenship identified is in frank movement and points to the uncertainty and complexity of the recent conjuncture of social protection in
Brazil. This is inserted in the basic dilema of the citizenship in the world, today: the increase of demand for social rights in competition with the demands of individual freedom and affirmation of differences.


One major problem in Africa in general is to convince governments and agencies that astronomy is relevant to Africa. Attention has been focussed on technology transfer, neglecting science and research. This attitude encourages the continued dependence on industrialized countries. In Nigeria there has been some success in projecting the idea that Space Science does not just mean remote sensing, but that basic space science, i.e. astronomy and astrophysics, cosmology, planetary science etc. is important and necessary. Evidence of this is that Nigeria's expert committee on space policy recommended that one of three proposed National Centres should be for basic space science, laying emphasis on fundamental physics, astronomy and astrophysics, solarterrestrial interactions and their influence on climate, planetary and atmospheric studies. In addition, the Government of Nigeria hosted the Third UN/ESA Workshop on Basic Space Science in October, 1993.

The horse conch, Pleuroploca trapezium is a marine gastropod that is landed in huge amount as by-catch along Gulf of Mannar. Their beautiful shells and operculum are being used for ornamental and medicinal purposes. Even though the meat is not being used locally, small quantities are being exported to Southeast Asian countries like Taiwan. These basic data relating to nutritional quality emphasize the need of promotion of this underutilized gastropod meat on par with other sea foods. Normally the sea food is preserved at a low temperature to reduce the post harvest loss and quality deterioration during extended period of storage. The shelf life of frozen stored Pleuroploca meat as such and after dip treated with chemicals was determined. The meat without any pretreatment had a shelf life of 4 months, while the meat dip treated with Orthophosphoric acid and Potassium nitrate had a shelf life of 5 and 6 months respectively. Thus Potassium nitrate can be used for dip treatment to extend the storage life of the meat under frozen storage.


Consistency and reproducibility of serum prostate‐specific antigen (PSA) measurement are essential in the application of this analyte to early detection or screening programs. In the present investigation, we sought to compare serum PSA levels determined by the IMx assay (Abbott Laboratories, North Chicago, IL) and the Tandem E (Hybritech Inc., San Diego, CA) to determine whether there were differences.


The author replies: Contrary to the response by Dr. Marik (1) to my Point-of-View article (2), it was not my intent to debate the desirability of enteral vs. total parenteral nutrition (TPN) in which there is little disagreement that early, adequate feeding by any means is beneficial in the critically ill (3). Rather, a hypothesis based on physiological considerations was proposed why TPN might be partially protective against the development of hypoglycemia vis-àvis enteral nutrition during intensive insulin therapy and also to propose future studies of enteral nutrition in which the goal for blood glucose level would be higher than euglycemia to limit perhaps the high incidence of hypoglycemia. A second point of contention is Dr. Marik's implication that enteral nutrition was not exclusively used in the medical intensive care unit study of intensive insulin therapy reported by Van den Berghe et al (4) because only 20% of calories was provided by enteral nutrition in that study (1, 4). It is important to distinguish parenteral nutrition from TPN. TPN is usually defined as parenteral nutrition containing all essential nutrients as well as hypertonic dextrose usually of at least 15% concentration and crystalline amino acids with or without additional parenteral lipid as the principal sources of energy. No TPN as so defined was used in that study and parenteral calories were as standard glucose solutions except during the first 24 hrs (3). The results simply demonstrate how commonly enteral nutrition is inadequate in the first week in critically ill patients as it was in the second Van den Berghe study (4) and probably serves as one major factor in the high incidence of hypoglycemia with intensive insulin therapy during enteral nutrition. Third, Dr. Marik proposes that TPN be compared with enteral nutrition in patients with pancreatitis as to outcome (1, 5, 6) rather than in those who are critically ill in the intensive care unit as with the Simpson et al meta-analysis (3). Hyperglycemia in the preintensive insulin therapy era was much more common with severe pancreatitis than in other conditions, presumably because pancreatitis commonly impacts insulin secretory capacity (7). Whether this difference in outcome between enteral nutrition and TPN in pancreatitis will be obviated by intensive insulin therapy will require further study. However, it does seem reasonable to focus on the nutritional care of the critically ill who are in intensive care units (3) as a far larger group of interest. Finally, I have no argument with the preference of enteral nutrition over TPN when possible, but this should not take precedence over early and adequate feeding in the critically ill by all means necessary. The author has not disclosed any potential conflicts of interest.

We consider a symbol-asynchronous uplink non-orthogonal multiple access (NOMA) model with equal-power transmission, where ${K}$ users transmit their codewords to a common receiver in an asynchronous manner. The received signal vector is an asynchronous superposition of all users' codewords. Due to the equal-power transmission, such signal detection scheme as successive interference cancellation (SIC) is invalid. We propose a message passing (MP) detection for the symbol-asynchronous NOMA system and analyze its performance by deriving a signal-to-interference-plus-noise ratio (SINR) of the detector output. Our analysis and simulations show that symbol asynchronization, i.e., each user has a different transmission time offset, in fact benefits signal detection, and its performance depends on the employed modulation waveform.


Material scientists regularly acquire and analyze infrared images of deforming objects in their material tensile deformation, crack propagation, and fracture toughness tests. Although there are many image processing packages, none of them are available in a database integrated fashion. Material scientists typically select a set of image files satisfying given constraints by browsing a file directory/catalog, and then perform simple but labor-intensive contentquerying on the images. These simple queries take days to answer. A more serious problem is that material scientists are not equipped with the flexibility to query images across different time snapshots or materials to validate their research hypotheses. In this paper, we report about our work on helping material scientists accelerate their work. Specifically, we propose a database approach to solve the problem of storing images and querying the content of images. In particular, we (1) proposed to use map algebra operations to compose image content querying needed by material scientists; (2) developed an SQL integrated image data cartridge which implements a core set of map algebra operations needed by material scientists; (3) analyzed the query processing and evaluation challenges; and (4) empirically evaluated the performance of three approaches, namely a multi-dimensional array based approach, a relational table based approach, and a binary large object (BLOB) based approach on bulk loading and typical material science queries using both real and synthetic data.


This paper proposes an unsupervised learning model for classifying named entities. This model uses a training set, built automatically by means of a small-scale named entity dictionary and an unlabeled corpus. This enables us to classify named entities without the cost for building a large hand-tagged training corpus or a lot of rules.Our model uses the ensemble of three different learning methods and repeats the learning with new training examples generated through the ensemble learning. The ensemble of various learning methods brings a better result than each individual learning method. The experimental result shows 73.16% in precision and 72.98% in recall for Korean news articles.


We revisit the work of Lehn–Lehn–Sorger–van Straten on twisted cubic curves in a cubic fourfold not containing a plane in terms of moduli spaces. We show that the blow-up Z′ along the cubic of the irreducible holomorphic symplectic eightfold Z, described by the four authors, is isomorphic to an irreducible component of a moduli space of Gieseker stable torsion sheaves or rank three torsion free sheaves. For a very general such cubic fourfold, we show that Z is isomorphic to a connected component of a moduli space of tilt-stable objects in the derived category and to a moduli space of Bridgeland stable objects in the Kuznetsov component. Moreover, the contraction between Z′ and Z is realized as a wall-crossing in tilt-stability. Finally, Z is birational to an irreducible component of a moduli space of Gieseker stable aCM bundles of rank six.


In real-time footstep planning for the humanoid robot, it is needed to obtain the accurate location of its foot placements. However, existing methods only needed to obtain the localization of the robot as a particle, which did not specifically consider the localization of its foot placements. This paper presents foot placement localization method for humanoid robot in human-living environments. A Kinect sensor was first used to obtain the digital map of the global environment and the position and orientation of the head of the robot was then extracted. The position and orientation of the foot placement was then calculated based on the spatial geometric relationship between the head and the target foot. The proposed method was used in the real time footstep planning in dynamic human-living environments. Experimental results validated its feasibility.


Deforestation leads to a significant loss of carbon and contributes indirectly to climate change. This study was carried out in four types of formations in the Sudanian zone of Burkina Faso to assess the contribution of plant species to climate change mitigation. The below-ground biomass of two species (Piliostigma reticulatum and Guiera senegalensis) was determined by the direct method. Three classes of subjects were determined and a total of 80 shrubs of P. reticulatum and 90 shrubs of G. senegalensis were completely excavated. The results showed that P. reticulatum measures about 0.49 to 2.10 m in height, 3.58 to 25 cm in circumference at the base of the trunk and stores 0.18 to 3.68 tC/ha in the root biomass (respectively after 3 years and 15 years) for a 3x3m plantation. In the 15-year fallow dominated by G. senegalensis stands, 3.93 tC/ha are stored by the underground biomass of G. senegalensis shrubs. Model fit showed that there is a good correlation between circumference at the base of the trunk and below-ground biomass for P. reticulatum. For G. senegalensis, it is the total height of the foot that is most correlated with the below-ground biomass. These results provide information on the carbon sequestration potential of these two species, and can thus help in the decision-making process for climate change adaptation and/or mitigation policies.


Objective To get knowledge of the awareness,treatment and control rates of hypertension of rural elderly people in Yantai,and the influence factors. Methods Taking the method of Multistage stratified random cluster sampling,a research of 14 districts' rural elderly 4 200 in Yantai were made,considering 912 hypertensive patients to do the questionnaire interview and physical examination and statistic analysis. Multiple logistic regressions were used to examine socio-demographic factors associated with the levels of awareness,treatment and control of hypertension. Results Hypertension awareness,treatment,control rate and total control were 76. 86%,65. 35%,44. 97%,29.39% respectively in rural area of Yantai. The main effect factors on the rates of hypertension awareness were gender,BMI,drinking,smoking,family history of hypertension and physical activities. The rates of treatment were associated with monthly income,occupational type,drinking,family history of hypertension and physical activities,and the rates of control were drinking and physical activities. Conclusions The rates of hypertension awareness,treatment and control are expected to be improved in rural areas of Yantai. The effective preventive and control strategies should be concentrated on the influence factors of the disease.


Abstract Context: Owing to the increasing number of cancer cases, and introduction of newer drugs like bisphosphonates (BP) for the management of metastatic bone disease, complications such as bisphosphonate-related osteonecrosis of the jaw (BRONJ) have come into light. However, several of the treating physicians are not fully aware of this adverse effect. Aim: This study aimed to assess the knowledge and awareness of physicians regarding BRONJ and practices related to bisphosphonate use. Settings and Design: A cross-sectional study conducted among health-care professionals in various medical institutions in Mangalore. Subjects and Methods: A questionnaire was developed to assess the knowledge and awareness of physicians about osteonecrosis of the jaw and practices related to bisphosphonate use, consisting of 21 questions, 12 – knowledge based and 9 – practice based. The questionnaire was validated and distributed among 113 doctors; their responses assigned scores, tabulated and assessed. Statistical Analysis: One-way analysis of variance and Tukey test. Results: More than 50% of the medical professionals had a score <40%, which shows a lack of knowledge about BP and BRONJ. About 45% of the medical professionals in the study group failed to identify the clinical features of BRONJ, and 67.26% were unaware of the risk associated with tooth extractions and oral surgical procedures in the development of the condition. Conclusion: Bisphosphonate-related osteonecrosis is almost exclusively seen in the jaws and hence, the diagnosis usually made by a dental practitioner. Lack of awareness of jaw osteonecrosis among the medical practitioners can result in delay in providing the right treatment.


An extinction ratio tunable optical fiber polarization interferometer (OFPI) is proposed and implemented to increase the optical modulation depth in radio-over-fiber (RoF) systems by suppressing the optical carrier power. The extinction ratio of the OFPI can be simply tuned by adjusting the polarization state of the launched RoF signal. Experimental results illustrate that the receiver sensitivity and dynamic range of RoF systems are greatly improved using the proposed scheme.


This chapter presents a selection of songs that were sung in Barwar. Some of these were originally composed elsewhere, notably in the Ṭiyare region, and this is reflected by the occasional occurrence of forms that are distinctive of the Ṭiyare dialects. This applies especially to the lϵliyana wedding songs and the rawe songs, which existed in rich oral traditions in the Ṭiyare region before the destruction of the communities in the First World War. The lϵliyana songs (C1) were sung by women at various points in the celebrations of a wedding, such as the washing of the groom and the selling of the tree to raise money for the bride and groom.Keywords: Ṭiyare dialects; Barwar; lϵliyana wedding songs


This article examines the development, implications, and limitations of a series of performance measures to gauge the success of individual Manufacturing Extension Partnership (MEP) centers. The measures represent a shift in how MEP judges and evaluates center performance and a challenge in terms of how they are used, how they are interpreted, and how they are limited. The MEPis an important example of innovative public programs and consists of a public-private, performance-based partnership that seeks to improve the productivity, competitiveness, and technological capabilities of America's manufacturers, particularly small firms. The article makes two important contributions: (a) a comprehensive performance-management approach can be developed with a focus on program outcomes that are linked to long-term impacts and are not just stand-alone process measures or stand-alone outcome measures and (b) it is possible to develop valid and reliable measures for technology-focused economic development programs that can be used to report on and manage performance.


The properties of semi-insulating thick films of Zn-doped GaN grown by hydride vapor phase epitaxy have been studied using cathodoluminescence, transmission electron microscopy and electron holography techniques. We have mapped the depletion region in the vicinity of threading dislocations and we show that it is associated with sharp drops in cathodoluminescence (CL) intensity. The monochromatic CL images showed considerable intensity variations across the sample surface. These long-range variations in luminescence intensity were also found to be related to potential fluctuations in the regions between dislocations. Such variations could be due to surface states caused by polarization effects of dislocations and/or various surface treatments.

The results of fundamental and applied research on the development of dispersed catalysts, gas-diffusion electrodes and membrane and electrode assemblies (MEAs) for polymer electrolyte fuel cells (PEFCs) are discussed. In the first part, the electrocatalysis of the oxygen reduction reaction on dispersed platinum catalysts used for the preparation of fuel cell electrodes is briefly considered. The issue is analyzed mainly in terms of the size and structure of the catalyst particles. Next, efforts on the development and single cell testing of low catalyst loading gas-diffusion electrodes for PEFCs are reported in conjunction with the main parameters relating to the properties of the MEAs. The fuel cell polarization behavior is analyzed considering the effects of the structure and composition of the diffusion and catalytic layers of the gas-diffusion electrode, the cell temperature and gas pressure and the thickness and the water transport through the membrane.

A THE OLD SAYING GOES, Christmas is coming (eventually), the retail goose is getting fat, and millions of Americans are pumping dollars into the cash registers. At the same time, thousands of investors, perhaps with visions of the plumpness of this retail goose flashing dollar signs, seem willing to pay 20 to 30 times latest 12 months earnings for the shares of prominent general merchandise retailers, such as Sears Roebuck, J. C. Penney, Federated Department Stores, and May Department Stores. However, over the next several years, the financial pickings for investors in these shares may be somewhat leaner than current expectations. For one thing, the earnings that are so opulently appraised today may prove to be top of the cycle earnings and vulnerable to retrenchment in the next several years. To be more specific, between 1954 and 1964, general merchandise retail spending grew at a 4.5% annual rate. However, during this period there were three exceptionally strong years (1955 when volume expanded 9.6%, 1959 when it was up 8%, and 1964 when sales soared 9.9%), and following these unusual years, in the past, volume has corrected back to the long-term trend with an unusually bad year. After the strong 1959 showing, for example, sales expanded only 2.4% in 1960, and only 2% in 1961. In the earlier cycle, there was a delayed reaction, with the 9.6% advance of 1955 followed by a solid 5.5% jump in 1956. But then volume rose only 2.9% in 1957, and the gain in 1958 was a miniscule 0.9%. The point of all this is that retail sales (and its component general merchandise sales) are a function of personal disposable income, and 1964 was obviously a very exceptional retail year with volume growth well above the long-term trend. Not only were economic factors uncommonly favorable in 1964, but the weather was also extremely good, with the mix between hot and cold blended so as to stimulate maximum seasonal buying. 1965 may well prove to be another year of above average growth for general merchandise sales, but most experts do not foresee the estimated 8 % gain of the first six months being sustained throughout the year. In fact, already there is some apprehension because the recent cut in excise taxes has not stimulated spending to any degree. The Investment Research Department of a leading New York City bank recently projected a 6% gain in general merchandise sales for the full year, which suggests a definite slackening of the first half growth during the second six months of the year. A growth of 6% would make 1965 a good but not an exceptional year; however, the really salient point is that a 9.9% year followed by a 6% year implies that a slowdown in 1966, possibly extending into 1967, is a logical assumption. In fact, since 1964 and 1965 were both well above the long-term historical growth trend of about 4.5% annually, the slowdown or correction could be unusually pronounced and prolonged. The implications of a decline in the growth rate of general merchandise sales on retail profitability is considerable. Past results indicate conclusively that profitability is a function of the rate of change in volume rather than a function of the level of volume. For example, the pre-tax margin of 10 major general merchandise retailers declined from 6.6% in 1955 to 6.1 % in 1958, and from 6.8% in 1959 to 6.2% in 1960. As a result, although they posted gains in volume from 1959 to 1960, Sears reported a 2.5% decline in earnings, Penney showed a 14.5% drop, and Federated a 4.5% fall. In 1964 the pre-tax margin of the 10 retailers mentioned before reached a high for the last decade of 7.2%, but it is difficult to foresee further gains of material importance in profitability. This cyclical sensitivity of retail profitability reflects the operating leverage inherent in a relatively large amount of fixed costs (i.e., leases, lighting, overhead, interest, etc.) and the considerable costs, employment, and stock levels that have to be budgeted in advance. Thus the expectations of retailers as reflected in their budgets can have an important impact on profits depending on their rightness or wrongness. In fact, the somewhat disappointing first quarter earnings results for several major retailers in the face of solid gains in volume was partially a function of sales being slightly below budget with a disproportionate effect on earnings. For example, in the first half of 1965, Penney's sales Barton M. Biggs is a partner of Fairfield Partners, a private investment fund. He received his B.A. from Yale University and an M.B.A. with distinction from New York University. He was formerly a vice president in institutional research at E. F. Hutton & Co.


Most of the sectors like medical, manufacturing, entertainment, lifestyles are moving towards automation. It means there is an intelligent system which is used to control and automate all operations.  These automated systems are controlled by programmed processors, which are capable of taking decisions and equipped with expert algorithms. But on the other hand security of these automated devices is an issue. They can be hacked by a hardware or software Trojan. Software Trojan is easy to identify and remove, but hardware Trojan is not very easy task to be found out. This paper is focused on technology developed to detect hardware Trojan. It also presents different types of Trojan and its effects.


Age at childbearing is rising in most developed countries, creating a 'Postponement Transition' (Kohler, Billari, Ortega 2002, Mills et al. 2011). As women face reduced fecundity with age, women who delay childbearing may not be able to have children (Morgan & Taylor 2006, Schmidt et al. 2002). This involuntary childlessness is contributing to the rise in childlessness and to slowing population growth, and may have negative consequences for individuals and relationships (Mills et al. 2011). For women who delay childbearing and face infertility, assisted reproductive technologies offer assistance but are an expensive and stressful process (Greil et al 2010). During pregnancy and birth, older mothers are at higher risk of health complications (Mintziori et al 2013). These increased health costs are borne by the state, which is also affected by declining populations.


This paper proposes an adaptive redundant sequences method to reduce the PAPR values of OFDM signals.Using the PTS-OFDM system as an example,by setting a PAPR threshold in advance and adjusting the system parameters adaptively,the proposed method can effectively reduce the computational complexity of redundant sequences method,thus relieve the computation overload of the system while guaranteeing good PAPR performance.Simulation results verified the effectiveness of the proposed method.The scheme can also be applied to SLM method.


Plate and frame heat exchangers, equipped with titanium plates, are effectively solving a variety of corrosion problems in heating and cooling applications on seagoing vessels, particularly containerships, tankers, barges, U.S. Navy combat ships and dredges. These applications range from central cooling systems - or those handled directly with seawater - for engine jacket water coolers to fresh water coolers to generator engine coolers. Heating applications range from fuel oil heating to fresh water heating with steam to jacket water heating for in-port operations to aid in cold starts. Over the past 25 to 30 years, titanium has become recognized as perhaps the material best-suited for sea water service. Unalloyed titanium alloys are the group of alloys that possess the necessary formability for use in plate and frame heat exchanges. This article draws typical comparisons against Cu-Ni alloys as this group of alloys has traditionally been the accepted standard for use in marine heat exchanger applications.


The outbreak of the SARS-CoV-2 virus that caused the COVID-19 pandemic put all countries in the world in an emergency and alert situation, implementing control measures, such as social isolation and unit closures, with the school environment being a space for potential transmission risk. Thus, the objective of this work is to report the experience of the members of the Group of Technological Innovations in Higher Education: contemporary challenges of Faculdade Santa Maria, regarding the use of technologies in favor of education during the COVID-19 pandemic. It is a descriptive study, narrative of the type of experience report, carried out in a private college located in the region of the upper sertao of Paraiba. The work arose in order to demonstrate the experience of using technologies in the continuity of the evaluation process of the 2020.1 and 2020.2 academic semester, which began since March 17, where all the institution's on-site activities were suspended, extending until nowadays, as well as the perception of carrying out learning assessments via remote technology. During the implementation of remote education in the institution, the group developed several activities to support teachers and students who did not have mastery of various technological tools. The use of remote classes provided benefits and challenges among the academic population, since this tool was the only way to continue the school term, however difficulties such as not having access to the internet, difficulty concentrating during classes, among other aspects.


Researchers are expending considerable effort to develop the technology and methodology needed to identify and map within-field management zones for site-specific farming. Much of the research has focused on the use of either a high-density geographically referenced grid of soil samples or mechanical yield sensor measurements that record geographic positions and production levels. In either case, complex spatial models are generally used to extrapolate the various soil variables and production level information across the entire field. Both procedures produce a wealth of information, however, the analysis of soil samples tend to be quite expensive and the accuracy of mechanical yield measurements does vary. This study represents an ongoing effort designed to evaluate remote sensing as a tool for determining within field management zones. Color-infrared aerial photography and multispectral videography were used in concert to map and stratify two grain sorghum fields into regions or zones of homogeneous spectral response. A limited number of soil and plant samples were acquired to characterize the biotic and edaphic conditions within each zone. Results obtained during the first year of the study indicated that multispectral video can be used to develop within field management zones. Simple univariate analysis indicated that soil pH, Ca, and Fe were important variables affecting yield. Analysis of the yield data indicated that the economic returns from 17% of the first field and 20% of the second field were insufficient to recoup planting costs. Multispectral video also proved instrumental in modeling the spatial variability of yield. A significant negative correlation (r2 greater than 0.90) was obtained between the red spectral band and crop yields for both fields. Stratification, in this case using image data, reduces the number of samples required to characterize a field by reducing the variance associated within each stratum. Image data also provided a comprehensive view of each field that maintained the spatial connectivity between sites, thus reducing the need for complex spatial modeling.


Reynolds average simulation governing equations are derived for viscoelastic fluid turbulence using the Reynolds time-averaged method combined with the Navier-Stokes equations, the viscoelastic fluid finitely extensible nonlinear elastic-Peterlin constitutive equation, the viscoelastic fluid molecular conformation tensor transport equation, and the turbulence model. To identify the relevant viscoelastic terms, user-defined functions and the programming language C are used to write a simulation subroutine for the Reynolds average of viscoelastic fluid turbulence; this subroutine is embedded into computational fluid dynamics software to establish a simulation method for Reynolds average of viscoelastic fluid turbulence. Then, the flow field structure of viscoelastic fluid turbulence is analyzed. Using energy transport theory, expressions for the contribution of viscous, elastic, and Reynolds shear stress to the turbulent friction factor of viscoelastic fluid in a horizontal tube are established, and the turbulent drag reduction mechanism of the viscoelastic fluid is revealed. The simulated values for pressure drop, Fanning friction factor, and the drag reduction rate of viscoelastic fluid in tests are in good agreement with experimental values, and the average relative error is less than 12.37%. In addition, elastic shear stress is produced after the dissolution of drag reduction agents in water, which increases the turbulent friction factor; however, Reynolds shear stress is greatly reduced, and viscous shear stress is weakened by inhibiting the turbulence fluctuation, so the turbulent friction factor decreases; more importantly, the increase in the friction factor of the former is much smaller than that of the latter.


The determination of the water requirements and crop coefficient (Kc) of agricultural crops helps to create an appropriate irrigation schedule, and with the effective management of irrigation water. The aim of this research was to estimate the water requirement, Kc, and water-use efficiency (WUE) of potato using non-weighing-type lysimeters in four regions of the Kingdom of Saudi Arabia (Qassiem, Riyadh, Al-Jouf, and Eastern). Our results clearly show that the accumulated values of the measured crop evapotranspiration of potato derived from the lysimeters were 573, 554, 592, and 570 mm, while the accumulated values of the predicted crop evapotranspiration from Penman-Monteith equation based on FAO (Food and Agriculture Organization) were 651, 632, 672, and 647 mm for the Qassiem, Riyadh, Al-Jouf, and Eastern regions, respectively. The Kc values of potato obtained from the lysimeters were Kc initial (0.58, 0.54, 0.50, and 0.52), Kc middle (1.02, 1.05, 1.13, and 1.10), and Kc end (0.73, 0.74, 0.74, and 0.75) for the Qassiem, Riyadh, Al-Jouf, and Eastern regions, respectively. Based on the amount of water used and the yield achieved, the highest WUE (3.6 kg m−3) was observed in the Riyadh region, while the lowest WUE (1.5 kg m−3) was observed in the Al-Jouf region.


Higher conversion efficiencies require high operation temperatures that are difficult to obtain due to the actual thermo-physical properties of the nuclear fuels. The initial intrinsic thermal conductivity of the actual fuel pellets, mainly ceramics like structures (oxides, nitrides, carbides, MOX, beads) is low. The center of the pellet is near melting temperature while the cladding operation temperature has to be low. The fission products deposition and burnup effects are further dimming the thermal conductivity. More the cooling agent's chemical reactivity increases with temperature is another main reasons of keeping the operation temperature low. The usage of a hetero-structure of solid fuel soaked into a drain fluid is increasing the thermal conductivity. Properly shaped beads structure drives to the possibility of preventing most of the fission products of being stored inside the fuel lattice deteriorating its properties, being drained outside the nuclear reactor. This changes inspired from the nature, makes the nuclear reactor resembling with a plant having self cleaning and curing properties while operating at higher temperatures. Immersing the fuel into liquid metal higher operation temperatures are allowed due to increase in thermal conductivity by 3 to 20 times. Making the fuel beads shorter than the range of fission products,more » their trajectories end in the drain liquid that is tolerant to nuclear recoils damage. Due to better thermal conductivity the temperature field differences inside the nuclear reactor becomes smaller, allowing the operating temperature to rise significantly without safety concerns. There is possible to continuously remove the fission products by smoothly circulating the drain liquid. The low flow is needed to give time to short lives fission products to decay inside the reactor highly shielded volume. There are several fissionable materials and drain liquids matching which assure high operation temperatures, and allow He cooling, and high temperatures gas turbines cycles. The conversion efficiency might be higher than 70% depending on the chosen actinide / drain-liquid / cooling-liquid combination. The new concept on fission products continuous release and separation minimizes the waste and the total radioactivity stored inside the reactor to few weeks integrated operation amount remaining constant over the time. That makes the fuel's remnant radioactivity lower by a factor >100 than the actual reactors level. The fuel reactivity might be controlled by poisoning and transmutation or by assuring specific reactive geometries which to allow a ultrahigh burnup without the need of over-criticality loads. The fuel's deformability opens the way for interesting applications. The advantages of micro structured nuclear fuel are higher thermal conductivity, fission products removal, appropriate reactivity, higher efficiencies and longer fuel life. (authors)« less


We propose a new definition of the implicit surface for a noisy point cloud that allows for high-quality reconstruction of the surface in all cases. It is based on proximity graphs that provide a more topology-based measure for proximity of points. The new definition can be evaluated very fast, but, unlike other definitions based on the moving least squares (MLS) approach, it does not suffer from artifacts.


This paper presents a novel model predictive direct torque control( MPDTC) methodology for induction motors to remedy the drawback with large pulsating torque and stator flux output of the traditional direct torque control( DTC). On the basis of the mathematical model of an inverter driving induction motor,a discrete-time predictive model has been developed. By utilizing the online optimization algorithm,a cost function evaluates the square sum of torque and stator flux magnitude errors for each switching state in a two-level inverter. The voltage vector with the lowest error is then selected to be applied on inverter. The performance of the presented MPDTC scheme is compared with the traditional DTC. Simulation results show that the presented MPDTC scheme can reduce the flux and torque ripple effectively and lower the current harmonic distortion while inherit the fast transient response from the traditional DTC.


ABSTRACT Aim: Adolescence is a particularly vulnerable period for illicit drug use. The present study aimed to examine the prevalence of adverse childhood experiences (ACEs) among adolescents in a national addiction treatment sample, and investigate the role of ACEs in adolescent drug use. Methods: The study examined data from 260 adolescents, information on ACE exposure and drug use were obtained from retrospective chart review. Results: About 46.5% of the sample experienced at least one ACE and 25.0% experienced two or more ACEs. Results showed that exposure to household dysfunction was associated with drug-related substance use disorders (SUDs). Additionally, exposure to multiple ACEs was associated with SUDs, earlier drug initiation, and more severe drug use. Conclusions: Given that a significant proportion of adolescents presenting for addiction treatment had a history of ACEs, the associations between ACEs and deleterious patterns of illicit drug use highlight the potential adverse impact of ACEs on proximal outcomes in adolescents.


Abstract : The collisional mechanisms by which a high density expanding plasma transfers momentum to an ambient stationary background are examined, and applied to the example of a laser-produced plasma. Experimental measurements of collisional modification of the ion flow field confirm the treatment used for momentum transfer rates. A numerical model which simulates the collisional coupling of an expanding laser-produced plasma to a photoionized background is developed; the results are compared to laboratory data to assess the degree to which collisional coupling influences experimental interaction studies in which both collisionless and collisional effects may be important.

The distribution of vaccine-derived immunity is central to disease control efforts, but is often poorly known. In this editorial, we outline why evaluating the degree of vaccine-derived immunity is both important and problematic, and discuss the strengths and weaknesses of different methods that have been used to approach this challenge. Since Arthur Ransome postulated the critical role of population susceptibility in epidemic dynamics [1], it has been understood that population immunity plays an important role in disease control. Knowledge of underlying levels of population immunity allows us to appropriately target vaccination and anticipate outbreaks. A population's immune profile is the result of its demography, its history of infection and past vaccination activities (both campaigns and routine coverage). Because vaccination results from the actions of the public health community, one might assume that measuring the effect of vaccination activities on population immunity would be straightforward. However, the information public health officials have about the distribution of a vaccine is often inadequate for making strong inferences about the immune status of the population. In nations with less developed healthcare systems, where knowing population susceptibility might be most valuable, even the size and demographics of the underlying population may not be well characterized. Hence, we rarely have accurate direct estimates of population vaccination status and resulting vaccine-derived immunity. Measurement of vaccine-derived immunity The numerous impediments to estimating the amount of vaccine-derived immunity in a population include uncertainty in the size and demographics of the target population; uncertainty in how many people are ever vaccinated and how many doses those that are vaccinated receive; spatial or demographic clustering in vaccine uptake; and uncertainty in the immunogenicity of the distributed vaccine. These barriers can combine to create substantial uncertainty in the amount of vaccine-derived immunity in the underlying population, especially in particular subpopulations. The combination of uncertainty in vaccine-derived immunity and the fundamental properties of long-term epidemic dynamics (e.g., the honeymoon period [2]) can lead to large outbreaks, surprising countries with apparently effective control efforts, for example, the large measles outbreaks that occurred in Malawi and Zambia recently despite years of apparently successful control and high nominal vaccination coverage [101]. Fortunately, there are several options for collecting data on population immunity and vaccination coverage. Each takes a different approach to measuring the immunization status of the population, and each has its own caveats, costs, strengths and shortcomings. Much of this information is collected regularly as part of routine surveillance and public health activities and is aggregated at the national level. However, often owing to logistics or cost, some useful data (e.g., population serostatus) are rarely collected, despite their potential utility (Table 1). Measurement of vaccine-derived immunity: how do we use all the data?


Speckle tracking echocardiography with assessment of left ventricular global longitudinal strain (GLS) allows to identify early signs of cardiac dysfunction.
 The superiority of GLS in the prediction of all-cause mortality in the general population compared with LVEF is well known; in addiction GLS improves risk stratification and recognize early left ventricular dysfunction in several clinical setting.

 the aim of this study was to assess the diagnostic and prognostic role of global and segmental strain in the early identification of cardiac dysfunction in patients with myocardial infarction without persistent ST segment elevation (NSTEMI) and without obvious wall motion abnormalities and to assess the ability to predict the presence/extension of coronary artery disease in this population.

 an observational study was carried out enrolling 56 patients (median age 66 ± 11,7 years) admitted for NSTEMI. Electrocardiogram, echocardiogram with global and segmental strain measurement (GE's Automated Function Imaging) and coronary angiography were performed in all patients. In addition we measured territorial longitudinal strain (TLS) defined as the mean of peak systolic strain of the segments pertinent to the perfusion territories of each epicardial coronary arteries in a 17-segment LV model.

 mean LVEF was 53%. We found a significant relationship between GLS values and coronary artery disease extension: GLS -19,1 % ±5,7% in patients without significant coronary artery stenosis, -18,74% ±4,85% in patients with one coronary artery disease, -15,6% ±4,3% in patients with two coronary artery disease, -14,2% ±5,4% in patients with 3 coronary artery disease (p = 0,03).
 We also found a correlation between territorial strain value and corresponding coronary artery stenosis.
 TLS was significantly reduced in patients with significant coronary disease of the perfused territory for each artery (LAD TLS 15,1% ± 6,74 % vs -20,73± 4,47 p = 0,002; CX TLS -11,42 % ± 6,59 %,vs -17,06 ± 7,1, p = 0,0 05 , RCA -14,02 % ± 6,00 % vs-17,6 ± 5,21 p = 0,02).
 At ROC analysis we identified a TLS value of -16,9 % to identify patients with significant stenosis of LAD (sensibility 58,3% and specificity 89,4%, AUC = 0,74, P < 0,001), TLS -18,2% for circumflex artery (sensibility 86,2% and specificity 78,9%, AUC = 0,78, P < 0,001) TLS -18% for right coronary (sensibility 73,9% and specificity 56,2%, AUC = 0,67, P = 0,027)

 global and segmental strain measurement in patients with NSTEMI help to identify the presence and extension of significant coronary artery disease.


ZnS, an significant optical material in IR regions, is applied in many opto electronic systems where a suitable antireflection coating is required to enhance the transmission. In this paper, an antireflection coating on ZnS substrate is presented. The design involves a connection layer with Zns substrate, thin Y 2O 3 film, and 4 layer stack of Ge and SiO as high and low refractive index coating matetrials, respectively. The coating conforms to environmental stability standards and shows an average transmission of 96% for a given application in 3μm~5μm range with a peak beyond 98% at 4.2μm thick ZnS substrate.


Environment‐related degradation and lead leakage in perovskite solar cells have posed a big challenge for their commercialization. Here, design of superhydrophobic surfaces is demonstrated as an effective strategy toward these issues, in which thiol‐functionalized perfluoroalkyl molecules are employed to chemically modify the lead halide perovskite film and metal electrode via a vapor‐assisted self‐assembly process. Due to the van der Waals forces, the generation of self‐assembly monolayer prefers to pack in a dense way, resulting in the formation of a closest‐packed, crystalline‐like molecular array. This dense array is endowed with a low‐surface‐energy chemistry that can not only enhance the water and oxygen resistance of the completed device but also reduce the defect density on the perovskite surfaces. These merits eventually boost the efficiency of inverted perovskite solar cells up to 21.79% along with a substantially improved long‐term stability. More importantly, the thiol‐functionalized superhydrophobic array can immobilize most of the undercoordinated lead ions on the perovskite surfaces by metal‐thiol coordination effect, which results in suppressing the lead leakage from the water‐soluble lead halide perovskites. Therefore, an avenue is pointed out here to fabricate stable perovskite solar cells with reducing lead leakage, representing a substantial step toward practical applications.

INTRODUCTION In order to reduce the probability of flooding and its potential consequences, by 2015 the European Union requires Member States to draw up the flood risk management plans focusing particularly on prevention (Floods Directive 2007/60/EC). According to this focus, the Autonomous Province of Trento (Italy) developed an integrated methodology to produce hazard maps of its territory (Autonomous Province of Trento, 2014). Nowadays the most common approach to define hazard areas is using LiDAR data for mathematical modelling, most of all for debris flow phenomena. Despite the high resolution that characterizes LiDAR data, the results are often unreliable because of the input parameters. Indeed input data, required into models, is a question still open due to uncertainty determined by hydrology, rheological characteristics, availability of sediment, influence of vegetation, etc. Based on these considerations we understand the importance of integrating information to draw hazard maps. In this study we present an integrated assessment of all available information for the Province of Trento, that is advantageous both to understand the causes and effects of historical events and to hypothesize scenarios of events that may occur in the territory. Furthermore LiDAR data analysis allows to identify morphological evidences that indicate hydrogeological instability, which is very useful mostly where there's no possible to apply adequate mathematical model.


The capability of cucurbit[n]uril to align gold nanorods, leading to optical coupling into the infrared region, is shown. Cryo-TEM and tomographic imaging confirm the presence of aligned Au nanorods. Full electromagnetic simulations, which support the observed plasmonic modes and predict large enhancements in the inter-particle junction, are performed. This construct is then further utilized for surface enhanced Raman spectroscopy.


A new species of the genus Closterocerus (Hymenoptera: Eulophidae), Closterocerus oryzamyntor Gumovsky & Zhu sp. nov., is described based on morphological and molecular data. C. oryzamyntor is a larval endoparasitoid of a major pest of rice, Dicladispa armigera (Chrysomelidae: Hispinae). C. oryzamyntor is known so far only from Bangladesh, and only from this host. The species is characterized by the following morphological features: 1) deep sutures on the vertex of the male, connected to form a complete transvertexal suture in the female; 2) a comparatively long malar space, which is 0.3 times as long as the eye height, and 0.7 times as long as the breadth of the mouth; 3) predominantly pale femora, tibiae, tarsi and antennal scape; 4) the comparatively wide scape of the male, 2.6–2.7 times as long as broad; 5) the male pedicel, flagellum, coxae and gaster, which are all dark. Partial gene sequences of the 28S D2 ribosomal region were identical for all individuals sampled, but differed from two Closterocerus sequences on GenBank by 24 and 27 base pairs (about 6%). Both CytB and COI mitochondrial gene fragments demonstrated slight variation within the species, but no other eulophids have been sequenced for these genes, thus comparative data are lacking for these genes.


In this paper, we get a time-delay new financial hyperchaotic system by modifying an old financial hyperchaotic system. we study the stability of a time-delay financial hyperchaotic system via adaptive periodically intermittent linear control method. Stability is obtained by using Lyapunov stability theorem, adaptive update laws and differential inequalities. Moreover, some numerical simulations are performed to show the advantage of the applications of this method.


We conducted an investigation for remaining period and behavioral ecology of skipjack tuna (Katsuwonus pelamis) around the fish aggregating devices (FADs) in the sea near Yonaguni Island, Okinawa, Japan. Skipjack is known that it is altitude migratory fish and stays around an island and artificial fishing reefs [1]. The knowledge concerning skipjack ecology and behavior are still poor and the reasons for staying around FADs are unknown. Investigation of migratory fish has a wide movement range and it is difficult to track continuously long-term. For this reason, a method of attaching a data logger directly to a fish body and measuring behavior are mainstream. However, since this method requires recapture of fish for the data collection, the data collection rate is extremely low. In this study, we tried long-term research and improvement of data recovery rate using ultrasonic biotelemetry system and FADs dotted in the sea near Yonaguni Island, Okinawa, Japan. As a result of the investigation, it was possible to confirm received signals of 71 individuals out of the 181 individuals released. And it became clear that many of the received skipjacks stayed more than 10 days and stayed in the sea near Yonaguni Island. Furthermore, we were able to obtain about the migration between FADs and the diurnal behavior around the FADs.


This paper considers adaptive tracking control of robotic manipulators in Cartesian space coordinates. It is assumed that the Jacobian matrix of robot is known. A general Lyapunov-like concept is then used to design an adaptive control law. It is shown that the global stability and convergence can be achieved for the adaptive control algorithm. The algorithm has the advantage that inverse of Jacobian matrix is not required. The algorithm is further modified so that the requirement of boundedess for the inverse of estimated inertia matrix is eliminated. Results are also presented to achieve robustness to bounded disturbances.


The technology of orientation and levelling are recorded in the Yingzao Fashi(Treatise on Architectural Methods).However,the tools and how to operate them have not been explained exactly until now.Through examining and analyzing the articles about them in the Yingzao Fashi,the procedure of operating the tools are restored.At the same time,some mistakes in previous works are corrected and the insufficiency such as operation is also filled up to a certain extent,all of which is conducive for one to understanding the development of orientation and levelling in Song Dynasty.


This study investigates the role of socio-cultural factors in loan repayment among the Kikuyu of Nyeri district in Kenya. This is based on the premise that loan groups, being embedded in the local culture of the community they operate in, bring numerous local institutions into the micro finance arena. These institutions influence the administration and management of these groups in terms of formation, leadership, loan repayment as well as their survival. The objectives of the study are therefore to establish the power hierarchy within micro finance loan groups, to examine the socio-cultural sources of power and exercise within the group and to investigate the effects of these factors on loan repayment. The study makes use of both the social capital theory and New Economic Sociology paradigm as the theoretical framework. Data was collected from both primary and secondary sources. This was based on field interviews with borrowers, non-borrowers and loans officers in Mathira Division. Relevant literature on microfinance was also reviewed. The study findings show that socio-cultural factors affect participation, loan repayment, leadership and the survival of the groups. In the first place, social hierarchy in society influences aspects of group formation, savings and even loan repayment in MFI loan groups. Secondly, that the problem of unsatisfactory repayment rates is much more than a problem of poor economic conditions, rather a product of the intervention of various socio-cultural factors. Thirdly, that the exercise of power within the group does indeed influence leadership and group survival, whereby poor leadership it was concluded constitutes a barrier to the survival of any group. The study recommends training of borrowers on financial management as a way of lessening the occurrence of default. Partnership needs to be encouraged between the borrowers and lenders for effective flow of information between loan groups as well as between MFIs. Greater community participation in microfinance is important as a means to overcoming the challenge of capital formation at the local level. Finally, there is need for further research to examine the means of appropriately incorporating culture into savings and credit groups with a view to strengthen loan repayment.

Abstract Background From 6 to 10 July 2021, WONCA Europe and the Dutch College of General Practitioners as host organiser welcomed 1,266 family physicians/general practitioners, teachers, researchers, and students from 66 countries interested in sharing knowledge, experience and innovations in primary healthcare. Methods In cohesive sets of plenary presentations, round table sessions, and research masterclasses, aspects of patient care, research, and education around Practicing Person-Centred Care were presented and discussed. Actual topics in primary care such as covid-19, e-health and professional health, were covered in oral presentation sessions, one slide 5-minutes presentations, case presentations by young doctors and the e-poster gallery. All sessions were recorded and available on-demand for registrants until three months after the conference. All accepted abstracts have been published in the abstract book [https://www.woncaeurope.org/page/past-conference-abstract-books]. For this Journal, we selected the top 20 abstracts based on reviewers scores (mean of 3.5 or higher on a scale of 4) and consensus among members of the Scientific Committee. Results The selected abstracts are divided into the following themes: (1) clinical topics often encountered in primary care, such as acute chest pain, urinary tract infections, dementia, and covid-19 (N = 5); (2) personalised care and related issues such as addressing multimorbidity (N = 2); shared decision making and patient empowerment (N = 4); (3) overdiagnosis and overtreatment, focusing on deprescribing (N = 2); (4) health promotion and prevention, including mental health (N = 2); (5) quality and safety (N = 2); (6) professional development and education (N = 1); (7) research and innovation, including teleconsultation (N = 2).


: High power-density torque converter is prone to cavitation due to high circular velocity and low local pressure, consequently leading to performance degradation. Both experimental and numerical studies are carried out on the cavitation phenomena in a torque converter. A series of hydraulic performance tests are performed under different wheel speeds and charging pressures to reveal the relation between cavitation and operating/charging conditions. A full wheel transient cavitation model based on Rayleigh-Plesset equation is built to capture the two-phase cavitating flows inside torque converter under variant operating conditions. The stress-blended eddy simulation (SBES) model is adopted to calculate the turbulent behavior inside the torque converter. Both experimental and numerical results revealed that cavitation might occur under high pump speed, low speed ratio and low charging pressure conditions, and the cavitation degree increased with a decreasing speed ratio. The worst-case-scenario for cavitation is the stall operating condition. Large amount of cavitation bubbles are generated in the stator domain, blocked the main circular flow and reduced the mass flow rate, resulting in capacity degradation as high as 31%. The full wheel transient cavitation model is able to predict the cavitating hydraulic performance precisely. By considering cavitation, the maximum prediction error for torque ratio, capacity factor and efficiency is reduced from 30% to 5%.


A patch antenna system operating in the 2.4–2.5 GHz ISM band is proposed for in-band full duplex applications. The proposed antenna consists of a patch antenna, a modified 180◦ hybrid, and a defected ground structure. Fabricated prototype results show a measured bandwidth of 100 MHz and an isolation of −75 dB at the center frequency with an isolation of at least −50 dB covering the ISM band 2.4 GHz–2.5 GHz. The design also has a spherical directional radiation pattern, low cross polarization, and reasonable gain values.


Aim of the study The present study aims to estimate the prevalence and distribution of HPV genotypes and identify related risk factors among Turkish women. Material and methods 11 624 Turkish women attending our gynaecological clinic and expressing a desire for access to cervical cancer screening were assessed during the years 2014–2016. Cervical specimens were collected and transported using the HC2 HPV DNA Collection Device (consisting of a cervical brush and digene Specimen Transport Medium). Results Among these 11 624 individuals, positive HPV test results were obtained for 325 (2.79%), and negative results were observed for 11 299 (97.2%). The vast majority of patients were between the 3rd and 5th decades and the mean age of the patients was 44 ±9.12 (range 27–66). Among the HPV-positive women, 205 were positive for a single HPV type (205/325 = 63.1% of HPV infections; 205/11624 = 1.76% of all samples) and 120 were positive for multiple types (120/325 = 36.9% of HPV infections; 120/11624 = 1.03% of all samples). The four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively. Conclusions There appears to be geographic variation in the distribution of HPV genotypes. In this study, the four most prevalent high-risk types were HPV 16, 31, 51 and 52, with frequencies of 11.25%, 7.83%, 6.06% and 3.16%, respectively.

Cancer is dreadful disease very distressing to the people they are scared from cancer. Orofacial cancer includes groups of malignant disease effect the oral, nasal mucosa, jaws and salivary glands and parotid and mesenchymal surrounding structures of the orofacial regions. The incidence of head neck cancer is about 8% of the total body malignancies while oral cancer in general represent about 4%, that percentage might increase to 40% in India but in US and Europe the incidence very much reduced, but in the south of Iraq the incidence very much increased because, pollution of depleted uranium been used during gulf wars.


Page e8 As researchers and practitioners in the area of obesity, we are familiar with the different types of obesity that are prevalent and the alarming increase of younger children that are impacted globally. Moreover, we recognise the health problems concerned with the relationship between obesity and the lack of physical activity, with the drain on health funding with increased teeth extractions, type 2 diabetes and heart conditions, to name but a few. In an attempt to combat this global epidemic, there are many policies and interventions in place which work in conjunction to address obesity. One such example is the globally recognised recommendation by the World Health Organisation1 to encourage between 30-60 minutes of exercise per day, depending on age. However, to the general population, such advice seems too simplistic and neglects to recognize the difficulties that individuals have with becoming more physically active.


This thesis is concerned with the design and fabrication of flexible textile wearable
antennas integrated with the newly introduced artificial materials known as high
impedance surfaces (HIS). With the rapid growth and use of wireless communication
systems more and more people are taking advantage of portable computing systems on
daily basis. Also with the advancement in electronic industry new and sophisticated
wireless devices have been introduced which are being used closed to human body. For
user convenience there is an increasing need for integrating antennas on or in the clothing.
The conventional antennas being rigid and obtrusive to user movements have limitations.
There is a need of antennas made of flexible textile materials that can be part of user
clothing defined as wearable antennas. Also with the miniaturisation trend in electronic industry, antenna designers are facing a challenge to come up with a compact, low profile,multi function efficient antenna designs occupying a small physical space. By integrating
antennas in user clothing this limited space problem can also be resolved.
With the easy availability of electro textile materials it is now possible to manufacture
complete fabric antennas. The entire design cycle of wearable fabric antennas starting from
material selection to prototype fabrication and antenna testing was carried out in this thesis.
A novel technique for antenna fabrication using electro textile material is proposed that will have major implications on wearable computing industry.
The use of HIS for antenna performance enhancement is growing at a rapid pace. In this
thesis a modified wearable form of HIS defined as non uniform HIS is presented and successfully integrated with antenna for improved performance under low profile limitation. The HIS was also integrated with normal patch antenna to reduce its size and
improve its gain and impedance bandwidth.
These wearable antennas were then tested under real operating conditions. The measured
results validated the design idea and showed that there are many possibilities for these unique artificial materials to be exploited for future wearable on body communication antennas.


During an International Consensus Meeting on Drug-Induced Liver Disorders, held in Paris in June 1989, under the auspices of the Council of International Organizations of Medical Science (CIOMS) the participants were asked for a list of clinical or biological abnormalities of the liver or biliary tract which could be drug-induced, which were then defined. As a pilot project, the WHO Collaborating Centre for International Drug Monitoring in Uppsala, Sweden in collaboration with the organizers of the meeting, has proposed a revised version of section 0700 (Liver and Biliary Tract Disorders) of WHO-ART along the lines of the recommendations of the Consensus Meeting. Although the principal aim of the international meeting of experts was only to determine a group of accepted and defined adverse reaction terms, the extension of these recommendations as part of the WHO-ART hierarchical terminology improves its precision and its adaptation of evolving investigative procedures and to the description of new hepatic or biliary lesions likely to be drug-induced. In the expert review process (both for this organ and for other system-organ classes currently under review), it has been observed that there are important differences in general disease definitions given in major medical textbooks as well as in the understanding of some terms by experts from different countries. Sometimes no definitions have been available and no standards for diagnostic procedures established; in other areas firm pathological criteria for a diagnosis are widely accepted. In the latter case these have been included in the proposals or reference made to the appropriate way of confirming a diagnosis. For quantitative laboratory values the proposal advises that a change referred to a local laboratory normal value (N) be used in the majority of cases. In some instances critical ratios of laboratory results (R) are proposed. It is thought that the use of definitions and guidelines may aid all those reporting and analysing suspected drug adverse reactions. More consistent use of these recognized terms, however does not preclude the use of other descriptions of hepatic adverse drug reactions if necessary, nor does it imply that reports which do not use the terms completely as defined are of less public health import. The revision of the WHO-ART is based on:

After introducing the notion of an f -primary of a fuzzy automaton, this paper presents a decomposition of a fuzzy automaton (possibly with infinite state-set) as a union of its f -primaries. En route, it is also shown that the concepts of primaries and f -primaries of a fuzzy automaton coincide in the case of compact fuzzy automaton. c ©2011 World Academic Press, UK.

We report the discovery and orbital solutions for two new OB binaries in the Cygnus OB2 Association, MT311 (B2V + B3V) and MT605 (B0.5V + B2.5:V). We also identify the system MT429 as a probable triple system consisting of a tight eclipsing 2.97 day B3V+B6V pair and a B0V at a projected separation of 138 AU. We further provide the first spectroscopic orbital solutions to the eclipsing, double-lined, O-star binary MT696 (O9.5V + B1:V), the double-lined, early B binary MT720 (B0-1V + B1-2V), and the double-lined, O-star binary MT771 (O7V + O9V). These systems exhibit orbital periods between 1.5 days and 12.3 days, with the majority having P <6 days. The two new binary discoveries and six spectroscopic solutions bring the total number of known massive binaries in the central region of the Cygnus OB2 Association to 20, with all but two having full orbital solutions.


Resources are becoming more expensive and less accessible, for instance construction wood or semiconductors. In addition, climate change requires the conversion of the energy system to 100% renewable energy. Therefore, we need resources to prevent the climate crisis from worsening, but at the same time, we are suffering from a worsening resource crisis. State-of-the-art technologies, such as silicon-based photovoltaic or wind power plants, are harnessing renewable energy but causing problems and resource losses at the end of their useful life. This alarming situation must be addressed with renewable energy technologies that can be used longer, repaired and remanufactured, and properly recycled at the end of their useful life. An emerging technology that can complement the established systems is dye-sensitized solar cells (DSSCs). Their production is less energy intensive and they can be manufactured without toxic materials. In line with the concept of the circular economy, the service life of all products must be improved in order to reduce resource consumption. Therefore, we investigated the potential for remanufacturing DSSCs by taking apart old DSSCs, cleaning the components, and building new DSSCs from the remanufactured components. The remanufactured DSSCs have the same or higher efficiencies and can be remanufactured multiple times.


[n]Helicene derivatives are most popular chiral structures to construct luminescent materials with circularly polarized (CP) light, which have revealed appealing application in chiral optoelectronics. Particularly, because of the unique phosphorescent emission, platinahelicene has great application prospects in CP organic light-emitting diode (CP-OLED). Herein, by decorating the pyridinyl-helicene ligand with trifluoromethyl (-CF3) unit in a specific position, a pair of platinahelicene enantiomers was prepared and separated with extremely twisted structure showing not only superior thermal and configurational stability but also good CP luminescence (CPL) property with dissymmetry factors (|gPL|) of 6 × 10−3. Moreover, the evaporated CP-OLEDs based on platinahelicene enantiomers exhibited the deep-red emission with the peak at 653 nm as well as obvious CP electroluminescence (CPEL) signals with the |gEL| in 10−3 order. Therefore, the design strategy provides an efficient way to improve the CPL properties of platinahelicene to cope with the future application in CP-OLEDs.


Hypervelocity impact tests with bumper walled structure are conducted in a two stage light gas gun. The bumpers are made either of aluminum alloy, carbon/polyimide, flexible insulation + Al, 2.5D carbon/carbon + Al, fiber metal laminates, or ceramic. The impact velocity is about 4 km/sec. The debris cloud is visualized by the shadowgraph method or by using a multi-frame image converter camera. The damages to the main wall are compared among the bumper materials. The efficiency of the nonmetal bumper shielding is found to be superior to that of the metal bumper in both specific density and effectiveness protection.

In this work the pressure and temperature dependence of the combination reaction of hydrogen atoms with oxygen moleculesIn the experiments, the rate constants were measured at various pressures allowing the development of Falloff curves. A specialised type of Falloff curve was developed by Troe by means of SACM/CT calculations based on an ab-initio potential surface produced by Harding et al. Using these curves it was possible to extrapolate to limiting high pressure rate constants of the reaction, and determine the temperature dependence. A high pressure limit was obtained (bathgas independent):krec = (9.85 ± 0.55)·10−11 (T/300K) +0.51±0.14 cm3s−1.For the first time it was possible to determine the rate of reaction (1) nearing the high pressure limit and to determine the temperature dependence of the high pressure rate constants from ambient temperature to 700 K. The experimental results are consistent with the SACM/CT calculations, which were accomplished using the "state of the art" potential energy surface developed by Harding et al.
