Many natural and synthetic compounds, including a variety of the chemicals used as plasticizers or in the pro- duction of cosmetics and therapeutics, have steroid agonist or antagonist activities, altering hormone-regulated gene ex- pression. The phthalate (diethylphthalate, extensively used as a plasticizer and in consumer products, are evaluated using the human renal epithelial cell line 293T/17. Emphasis of the study was on genes essential for central nervous system de- velopment or function. Cells were treated with 1, 10 or 100 μM phthalate and gene expression was measured in treated cells, showing significant up- or down-regulation of a large number of genes in treated compared to untreated cells. Of the 19,000 human genes on the DNA array chip utilized, two specific genes, FGD1 and NGPF2, were selected to corroborate mRNA levels using quantitative real time PCR (qrtPCR) data to confirm results obtained from the microarray determina- tions. FGD1 (faciogenital dysplasia) and NGPF2 (neurite growth-promoting factor 2, also called Midkine, MDK), showed a significant, possibly estrogen-synergistic, down-regulation of genes essential for fetal brain development. These studies were designed to provide data on the gene expression-altering capacity of a widely distributed chemical, diethylphthalate (DEP), and to show possible associations between the previously reported widespread presence of DEP and the DEP me- tabolite, MEP, in urine samples from a reference population, the potential for altered gene expression in human cells in vi- tro, and possible neurodevelopmental effects that could be correlated with in utero exposure to DEP.

First published in France as Le Pagne Noir: Contes Africains in 1955. The writing of such chronicles of an African childhood was the author's way of coming to terms with the questions every sensitive colonized person educated in the Western tradition would sooner or later have to ask: Who am I? Where do I come from? Where am I going? While giving poetic and fictional expression to the tensions of independence and the events that led to it, the writer realized that he would at the same time have to rediscover his oral tradition. It was a natural development of what the new African poetry and drama in French, English, and, later, Portuguese, were already doing--probing the inner mysteries of indigenous mythology and symbolism. Only in this way could the enlightened African restore a sense of equilibrium in his people's culture. From the foreword by Es'kia Mphahlele, University of Witwatersrand, Johannesburg


The present work describes the progress on developing imaging algorithms that use fast neutron signatures acquired using the associated-particle imaging (API) method. The present work complements ongoing work to develop neutron source and detector hardware to enable field inspection by investigating algorithms that are capable of discriminating among critical materials or extracting three-dimensional (3D) geometrical information from single-sided or transmission measurements. The present work is divided into three approaches: Progress for each approach is summarized for fiscal year (FY) 2020.


The present experiment was conducted to evaluate the
influence of Lamiaceae herbs companion planting on growth and secondary
metabolites changes in tomato plants. Furthermore, the free amino acid changes
in tomato due to companion planting were also evaluated using tomato-basil companionship as a model.
Four-week-old seedlings of tomato were grown in a pot containing autoclaved
commercial soil with basil, peppermint and hyssop as a companion plant
separately in different density. Four weeks after companion planting, tomato
plants under 1:1 companionship with the herbs showed significant increase in
dry weights of shoots compared to control. Higher density of the herbs on the
other hand expressed a growth suppression on tomato possibly due to nutrient
competition. By the LC-MS analysis, shikimic acid and apigenin were identified
as the major secondary compounds found in tomato plants and 1:1 companionship
with basil seemed to have a positive influence on their content in tomato
shoots. On the other hand, in case of peppermint and hyssop, the increase was
observed in all parts of tomato plants. In addition, promotion in several free
amino acid contents was also observed in tomato plants with basil companion planting compared to
control. Thus, tomato plants grown with herb companion planting in 1:1 ratio
seems to have a positive impact on growth of tomato. This positive influence
might be related to the increase in some secondary metabolites and changes in
the free amino acids observed in this study.

Improvement of surface wave methods for constructing subsurface S-wave velocity structures by Tatsunori Ikeda Chair: Toshifumi Matsuoka Seismic surface waves are guided waves propagating on the surface of the earth. Although surface waves have a long history in seismological studies, the use of surface waves has not been common in geophysical explorations. In a reflection or refraction seismic survey, surface waves are regarded as noise to be eliminated. Recently, however, a seismic exploration method using surface waves has been dramatically developed mainly for engineering purposes. The surface wave method is attractive because it is non-destructive, low cost, and simple compared to other seismic methods. By the surface wave method, subsurface S-wave velocity structures can be efficiently estimated from dispersion of surface waves. Since S-wave velocity structures down to several tens of meters play an important role for evaluating local ground-motion amplification, the surface wave method is one of the most important geophysical methods to be established for earthquake-prone countries such as Japan. The surface wave method utilizes velocity dispersion of surface waves, which can be extracted from both passive and active seismic data by surface wave analysis. Since surface waves can be theoretically modeled for horizontally layered structures, S-wave


This paper seeks to highlight Excel spreadsheet as a mathematical tool in the creative teaching and learning of traditiona l counting systems in Papua New Guinea (PNG). PNG is known for its divers ity in culture and tradition and so this paper wants to take advantage of the available technology such as spreadsheet to articulate the so rt of diversity that exists in our traditional counting systems. In this paper 3 different types of traditional counting systems in certain parts of PNG are being discussed. The first traditional counting system fr om Mikarew village in the Madang Province, uses a base 2 counting system and is taught in the native language call 'Aruamu' or 'Big Man'. The sec ond one uses a base 5 counting system and comes from Manam in the Madan g Province. And finally from East New Britain Province, the tra ditional counting system is taught in the native language call 'Kuanu a' and uses a base 10 approach. Each of this traditional counting system has been taught in the past and at present but without the use of computer -based learning technologies. It is our intention however, that wit h the current expansion of the One Laptop Per Child project (OLPC) in Prima ry schools around the country, spreadsheet can be better utilized as a dynamic tool for mathematics education especially in this area of tr aditional counting. The paper concludes that the way forward for mathem atics education in Papua New Guinea, is to embrace technological tools like spreadsheet and use it creatively.


Wild-collected Drosophila melanogaster females were isolated in culture vials to initiate isofemale lines in the laboratory. Wing length and body pigmentation (thorax, abdominal segments 5, 6 and 7 and their sum) were measured in wild flies and in successive laboratory generations. Heritability was estimated by parent–offspring regression between wild-living flies and laboratory progeny or by calculating intraclass correlation between lines in each laboratory generation. For wing length, phenotypic variability was much higher in nature than in the laboratory, and the estimated heritability with parent–offspring regression (0.14) was significant but quite low. Within laboratory generations, intraclass correlation was much higher, on average 0.34. For pigmentation characteristics, variability in nature was similar to that measured in the laboratory. Parent–offspring regressions produced significant and high heritability values (range 0.40–0.62), except for abdomen segment 5. Intraclass correlations were also significantly greater than zero for all traits (range 0.22–0.47), including segment 5. The stability of the lines over successive laboratory generations was shown by the stability of the overall mean and by a strong positive correlation between family means of successive generations. The correlation across generations demonstrates a genetic repeatability of the trait and should be useful in experiments using isofemale lines.


The electrospinning technique provides non-wovens to the order of few nanometers with large surface areas, ease of functionalisation for various purposes and superior mechanical properties. Also, the possibility of large scale productions combined with the simplicity of the process makes this technique very attractive for many different applications. However, a key precondition is the ability to obtain bead-free fibres with diameters in the nanoscale range. At present the most normally used solvent for electrospinning PCL is chloroform, but this only leads to fibres in the microscale range. Consequently various solvent systems were studied in this study. The solvent mixture ethanol/chloroform was found to allow for nanofibers with a diameter several times smaller than the solvent chloroform. Also, it is hypothesized that magnesium fluoridated hydroxyapatite nanoparticles - poly (ε-caprolactone) (PCL) nanocomposite tissue scaffolds can be made more bioactive by using magnesium fluoridated hydroxyapatite nanoparticle. Increasing content of magnesium in structure changes degradation rate. The overall objective of this study is to fabricate and characterize electrospun magnesium fluoridated hydroxyapatite nanoparticle - poly (ε-caprolactone) (PCL) nanocomposite scaffold as substrates for bone tissue engineering. The electrospun nanocomposite was characterized by SEM, XRD, TEM and Mechanical testing.


In comparative studies responses of two populations are often summarized in stratified 2 ×K tables with ordinal categories. A test, called QEt test, is proposed for testing the homogenuity of the populations against non-linear alternatives in such tables. The asymptotic distributions of proposed test are obtained both under the null and alternative hypothesis. The powers of the QEt test and extended Mantal test are compared by simulation.

Dating violence is a complex problem determined by multiple factors. Poverty, cultural and social environmental factors are a major contributor to the gender based violence. The aim of this study was to examine the nature and extent of dating violence experienced by students at the University of Zambia. Eighteen students (nine males and nine females) aged fifteen to thirty years were recruited from the University of Zambia hostels. In-depth interviews with semi-structured interviews were used for data collection. This study has found that various forms of dating violence exists at the University of Zambia. The study further found risk factors that were associated with dating violence such as consumption of alcohol and/or use of entertaining substances, as well as being involved in aggressive activities such as fighting or insulting; other factors included; poverty,
experiencing of inter-parental violence and prior experience with violence. The psychological and emotional implications were that some students became depressed and stressed, insecure, ideated suicide, feared sex, distrusted people and were worried and uneasy. Under physiological and health outcomes, some students contracted STDs and HIV, body injuries, became pregnant, and others lost or terminated their pregnancy. Furthermore, social implications were that some students became aggressive, went into self-isolation, and began living recklessly. Physical abuse, verbal abuse, sexual abuse and psychological or emotional abuse where the most common types of dating abuse found at the University of Zambia. Conclusively, In addition to awareness against gender based violence, youth friendly corners should be considered during the treatment of gender based violence in universities.


The behavior of a uniformly sampled queueing system is characterized and interpreted using a time series approach. The advantages of employing time series to obtain a model of the queue's behavior are shown to be simplicity, flexibility and reliability. An analysis of actual queue data shows that the queue behavior of a uniformly sampled queueing system with a single server and Poisson-exponential activities is adequately described by a first order autoregressive model. The autocorrelation function is used to relate queueing theory and the time series model to obtain the commonly required parameters for a queueing system, in a manner independent of the mean level of the queue.

Laser interaction with biomaterials frequently takes place under conditions of relative motion between the laser beam and the tissue. In this paper we compute the temperature rise induced in skin tissue by a moving Gaussian CW beam. Temperature profiles are obtained and effects of such parameters as scan velocity are analyzed. We employ these results to estimate the extent of the material removal regions.Laser interaction with biomaterials frequently takes place under conditions of relative motion between the laser beam and the tissue.

The Hungarian-born, Jewish sociologist Karl Mannheim (1893–1947) received his higher education in Germany, taught by Georg Simmel, among others, and worked for some time for Alfred Weber, Max's brother. Mannheim had become professor of sociology in Frankfurt when, in 1933, he felt the need to quit Germany and the new Nazi regime for England, where he enjoyed a short but successful academic career. In his essay "The Problem of Youth in Modern Society, published in 1943, Mannheim developed the idea that every society will have problems with its youth. The younger generations have no a priori vested interest in the society they live in: on the contrary, the existing social, economic and cultural order has been forced upon them, and they feel no natural loyalty to the established social system. Youth will not necessarily show interest in the established society, they would rather be inclined to question the order of older generations, their politics and policies, their social norms. And herein lies the core of every youth revolt at any time. The revolt and its intrinsic ideas, values and morals are also the seeds out of which alternative systems of social life can grow and evolve – as an idea or as experimental islands within and without the establishment. Mannheims generational theory, further elaborated in his essay "The Problem of Generations", has of late, following a long fallow period, been brought to the fore anew – a development that, however, only in isolated cases can be found in Nordic social science. The value of supplementing the classic sociological categories class, gender and ethnicity (race) with a generational perspective is aptly demonstrated by Alex Dumas and Sophie Laforest in their analysis of the difficulties encountered by the modern skateboard generation when seeking acceptance for the skate culture and the need for considerable investments that accompany the sportification of skateboarding. The empirical material is gathered at the skateparks of Montreal; eleven of them have been studied during a two-year period by observation (383 days) and 23 in-depth interviews with young skaters of various ages and of both sexes. The authors also performed a press review of the most topical issues related to the local skateboarding scene. The skate culture can certainly be considered an alternative cultural expression – and skateboarding definitely an alternative sport – quite in line with Mannheim's theory, and the skaters are more or less frustrated at every point in their quest for acceptance and places to perform their sport. Local authorities as well as local inhabitants seem to find the skaters a nuisance and a threat. Dumas' and Laforest's study and their article for idrottsforum.org offers valuable insights into a crucial part of sociological theory development, as well as a picture of the skater generation, its composition, its common values and its goals; and beyond that they present the essential features of the process of sportification and of the difficulties in creating legitimacy for new, generational sports.


Molybdenum dioxo bis acetylacetonate shows a retention of about 31 % for both " M o and 1 0 1 Mo, with reactor irradiations at ambient temperature. But its radiolytic stability and resistance to hydrolysis are too low for application to " M o enrichment. The molybdenum(II) carboxylates and the arene molybdenum (O)tricarbonyls show high retentions. These complexes are also air and water sensitive in solution. Very few satisfactory recoil enrichments of " M o have been described although such a process would avoid the need for separated 98 Mo in the production of high specific activity " M o for medical application. It seems doubtful that a satisfactory separation can be found that is based on the use of a Mo(VI) compound. Thus it appeared profitable to explore the possibilities of some complexes of molybdenum in low oxidation states. Indeed, the most satisfactory separation so far reported [1,2] is that using the molybdenum (O) hexacarbonyl, but the low radiolytic stability of this compound would probably preclude its use for the production of "Mo. More recently a reasonable yield has been reported for the much more stable cluster halide [3]. There are many complexes of molybdenum in low oxidation states, which are soluble in organic solvents, and it was hoped that the recoil product might be extracted from such a solution by an aqueous reagent. Such treatment could be expected to lead to hydrolysis of the recoil product probably accompanied by oxidation of the *Mo to the hexavalent state. Both 98 Mo and 1 0 0 Mo have reasonable abundances and thermal neutron cross-sections so that measurements are possible on both the 66.7 h " M o and the 14.6 min 101 Mo as products.


The three commonly used treatments for prostate cancer are: radiation therapy, surgery, or combination of radiation and surgery. Our present study is using real prostate cancer data from Surveillance Epidemiology and End Results program (SEER Database) to evaluate and rank the effectiveness of these treatments using both parametric and survival analyses. In addition, the evaluation of the subject treatment is based on the stage the prostate cancer has been classified.


Pine shavings poultry litter from four growouts was analyzed for particle size distribution and chemical composition. Little change in the particle size distribution was observed after the first growout. The majority of the nutrient mass was associated with the larger size particles [those failing to pass a size 50 (0.297 mm) sieve] while the nutrient density increased with the smaller size fractions. Crude fiber decreased while ash and crude protein increased as particle size decreased.


The invention discloses an IEC61850/Manufacturing Message Specification (MMS) simulation method of concurrent signals of multiple devices. The IEC 61850/MMS simulation method comprises the steps as follows. Substation configuration description (SCD) files are imported, and the devices and signal libraries thereof are analyzed. Communication service of each device is started. Initialization of signal upward transmission is finished. A shared memory where commands are stored is established, and furthermore a command bus is established. Each device extracts the signals to be upward transmitted from respective signal library and establishes mapping tables associated with the signals. The commands are transmitted to the command bus through a local server interface program. The devices simultaneously receive the commands from the command bus, extract the corresponding signals through the mapping tables according to the received commands, and immediately transmit the signals. The devices can receive the commands at the same time through establishment of the command bus. A report polling mechanism is changed into immediate transmission of assigned signals. The IEC 61850/MMS simulation method of the concurrent signals of the multiple devices has high real time performance. The efficiency of signal transmission is raised by many times. The data mapping is established for all of the transmitted signals. The signals are not needed to be searched when transmitted, and the communication efficiency is greatly improved.


Two new species of the family Brachychthoniidae Thor, 1934 from the Comoro Islands are described. One of these also represents a new subgenus, Liochthonius (Afroliochthonius) subgen. n.


Students do not always realize the value of schoolwork because they often fail to understand the relationship between the themes to be learned and results valuable to their life, what makes them not engaging in the activities. On the other hand, there is only a very limited number of surveys on the subject of the perception of science in general and mathematics in particular by the public in Brazil, making it difficult for the Brazilian professor to have solid data to identify themes of interest to the real world of their students. We intend with this work to demonstrate how, through the Google Trends Big Data application, this need can be filled, even partially, and how, through it, the Brazilian professor of mathematics education may identify topics of interest to their students' real world.


While a considerable amount of research effort has been devoted to modeling seaport systems, models capable of producing results that match the data are proving elusive. In this paper, we have contributed to the literature which models port systems as the queuing processes and builds a general equilibrium model which is suitable for both the analyzing of a number of potential determinants of the systems behaviour, and the carrying out of a numerical analysis of the port system operation indices. Furthermore, we seek to establish the potential role played by various elements that impact the operational behaviour of the system. The proposed model is tested with real data of the Bakar bulk cargo terminal. Using several years data set, we have synthesized variances in terminals' operation indices. Following the assumption that the discharging terminal for bulk cargo presents the queuing system type M/M/1, while the loading terminal shows the behaviour of the queuing system type M/D/1, the goal is to create the simulation model that will result in the functional explanation of the behaviour indices and assist in the decision making procedure to improve the effectiveness of the seaport system.


This paper examines the impacts of Land use activities on the Hydrogeomorphic characteristics of Lakes in the Upper Benue Valley Area of Adamawa State. Four major lakes in the area were purposively sampled out for the study based on their apparent sizes and relevance. The study involved an assessment Land Use/Land Cover changes in the area from 1987 to 2013 using Landsat TM Imagery of 1987and Landsat ETM+ imageries of 1998 and 2013, as well as identification of major human impacts on hydrologic and geomorphic characteristics of the lakes by field observation and interview schedule. Using Purposive Sampling Method, 60 respondents were selected from a settlement in the vicinity of each of the lakes for interview schedule. Results showed that vegetation cover in the area decreased by 30, 696.43Ha from 1987 to 1998 and further decreased by 16, 015.50Ha from1998 to 2013, while farmlands increased by 169, 303.57Ha from 1987 to 1998 and further increased by 16, 549.41Ha from 1998 to 2013. Surface water bodies decreased by 533.85Ha from 1987 to 1998 and further decreased by 800.78Ha from 1998 to 2013. Deforestation, farming practices and urbanization were identified as major human activities, affecting the hydrogeomorphology of lakes in the area through the enhancement of runoff, sediment and pollutants loading into the lakes. Monitoring siltation rates and dredging are recommended as sustainable measures for the lakes.

Abstract Male contraception is a very active area of research. Several hormonal agents have entered clinical trials, while potential non-hormonal targets have been brought to light more recently and are at earlier stages of development. The general strategy is to target genes along the molecular pathways of sperm production, maturation, or function, and it is predicted that these novel approaches will hopefully lead to more selective male contraceptive compounds with a decreased side effect burden. Protein kinases are known to play a major role in signaling events associated with sperm differentiation and function. In this review, we focus our analysis on the testis-specific serine kinase (TSSK) protein family. We have previously shown that members of the family of TSSKs are postmeiotically expressed in male germ cells and in mature mammalian sperm. The restricted postmeiotic expression of TSSKs as well as the importance of phosphorylation in signaling processes strongly suggests that TSSKs have an important role in germ cell differentiation and/or sperm function. This prediction has been supported by the reported sterile phenotype of the Tssk6 knockout (KO) mice and of the double Tssk1 and Tssk2 KO mice and by the male subfertile phenotype observed in a Tssk4 KO mouse model. Summary sentence The established role of TSSKs in spermiogenesis and in male fertility, together with their unique kinase features, strongly supports this family of protein kinases as a very promising drug discovery target for development of a non-hormonal male contraceptive.


This article is an adaptation of the doctoral thesis, Exile: between roots and radars, on Brazilians in exile between 1964 and 1979, which relates this experience through the exiles themselves: their life stories, activities and their work, recovering the memory, not only of the well known, but, above all, giving voice to the anonymous ones. In it, I deal with day-to-day life in exile: doubts, certainties, agonies, the void, fear, madness, death, the problems with documents, work, studies, reconstruction of their life paths, in brief: the redefinition of identities that day-to-day life imposed on the men and women who lived through this experience, at once painful and fascinating.


Identification and characterization of a novel member of the ATP-sensitive K (cid:1) channel subunit family, Kir6.3, in zebrafish. Physiol Genomics 24: 290–297, 2006. First (cid:1) (K ATP ) channels play a crucial role in coupling cellular metabolism to membrane potential. In addition to the orthologs corresponding to Kir6.1 and Kir6.2 of mammals, we have identified a novel member, designated Kir6.3 (zKir6.3), of the inward rectifier K (cid:1) channel subfamily Kir6.x in zebrafish. zKir6.3 is a protein of 432 amino acids that shares 66% identity with mammalian Kir6.2 but differs considerably from mammalian Kir6.1 and Kir6.2 in the COOH terminus, which contain an Arg-Lys-Arg (RKR) motif, an endoplasmic reticulum (ER) retention signal. Single-chan-nel recordings of reconstituted channels show that zKir6.3 requires the sulfonylurea receptor 1 (SUR1) subunit to produce K ATP channel currents with single-channel conductance of 57.5 pS. Confocal microscopic analysis shows that zebrafish Kir6.3

A 77-year-old woman was brought to the accident and emergency department with a 11-day history of abdominal pain. She was in shock and required resuscitation. She had attended the accident and emergency a few days before and had been discharged home with a diagnosis of non-specific abdominal pain. The previous abdominal X-ray is shown in Figure 1. Her past medical history included bilateral below knee amputation for peripheral vascular disease, pacemaker for heart block and hypertension. On examination, post-resuscitation, she was confused and apyrexial with a heart rate of 100 beats/minute and a blood pressure of 110/70 mmHg. Her abdomen was diffusely distended with minimal tenderness in the epigastrium and supra-umbilical region. There was no rigidity or guarding. Bowel sounds were normal. Digital rectal examination showed soft faeces. Blood test showed a haemoglobin of 6.6 g/dl (down from 11 g/dl during her previous accident and emergency visit). There was slight impairment of renal function with a ure...


The regenerating central nervous system of goldfish contains peptides referred to as glia-promoting factors (GPFs) that stimulate the proliferation of mammalian macroglia. We find that, in vitro, GPF1 and GPF3 promote the appearance of oligodendroglia and GPF2 and GPF4 stimulate proliferation of astroglia. The activities of GPF1, GPF3, and GPF4 increase during regeneration of the goldfish visual system. These results suggest that brain peptides may play a role in the recovery of the injured central nervous system by regulating the growth and development of specific macroglial populations.


3D models of(interior,surface and corner) unit cells of the 3D braiding preform were established based on the characteristics of 3D entity modeling of Pro/E.Parameterized models were designed.Every kind of unit cell model can be auto created under different braiding parameters,and according to Pro/E model— analyzed function,the fabric volume of a cell can be output directly.The calculation formula of the perform fabric volume fraction was proposed based on parameterized cell models.The fabric volume fraction of the rectangular perform was calculated,and it is well in agreement with experiment result.The fabric volume fraction of annular sector perform was also calculated.It provides a new method for calculating fabric volume fraction of complex shape.


In a typical model-based collaborative filtering with implicit feedback, negative sampling is getting more and more popular to obtain negative labeled inputs from massive unobserved data. However, this approach wrongly samples false negatives, resulting in unacceptable recommender model. In this work, we first identify a situation where false negatives are problematic and estimate their impact on a model accuracy. Then, we take our negative sampling as a classification task and demonstrate that a recommender model and a negative sampling method actually share the same goal: identification of false negatives from other unobserved data. We also estimate the actual upper bound of the accuracy improvements with a feasible negative sampling. Lastly, we propose a generalized negative sampling that can alleviate the impact of false negatives by introducing two robustness against false negatives: self-sampling and dynamic sub-sampling. In user-item interaction matrix, experimental results on publicly available datasets show that our approach outperforms some state-of-the-arts with statistical significance.


Purpose – The aim of the research is modeling and implementing a software component for the retrieval of bibliographic records using the Apache Lucene retrieval engine.Design/methodology/approach – Object‐oriented methodology is used for modeling and implementation of the bibliographic record retrieval engine. Modeling is carried out in the CASE tool that supports the unified modeling language (UML 2.0), while the implementation is using the Java programming language and open source components.Findings – The result is a software component for the retrieval of bibliographic records that are independent of the bibliographic format used in cataloging. It features great flexibility in terms of configuring search types without the need to change the software implementation.Research limitations/implications – One of the constraints of this system relates to the problem of searching linking entry fields. UNIMARC format defines fields used to link the item being cataloged to another bibliographic item, so those f...

Public concern has arisen between increased productivity in animal production systems and farm animal welfare (FAW). Consumers demand ethical production systems and tend to purchase products that reflect their animal welfare concerns. They are becoming increasingly judicious, with growing expectations around animal produce. Nonetheless, positive attitudes concerning FAW do not always correspond to purchasing behavior, where higher concern is not related to higher purchasing frequency. The study seeks to determine if individuals behave differently in their dual roles as citizens and consumers, expressing preferences for FAW but ultimately failing to act on such preferences when making purchasing decisions. Theoretically, the research uses elements of the COM-B model to investigate the importance of capability, opportunity, and motivation for consumers. The study is conducted on an island of Ireland basis and investigates the perceptions and purchasing frequency of Irish and Northern Irish consumer's (n = 972). Firstly, attitudes towards purchasing animal welfare products are elicited using Categorical Principal Component Analysis (CATPCA). Cluster analysis subsequently defines three distinct typologies based upon the final cluster centers attained from CATPCA. The largest cluster is characterized as being Indifferent (n = 672) and differentiated by relatively low concern for animal welfare. Despite this, their purchasing frequency of animal welfare products is monthly. The other two clusters, The Engaged and The Struggling, are similar in size and share the same concern for animal welfare but are polarized in their motivation, capability, and opportunity to purchase animal welfare friendly products. The Struggling typology act as citizens rather than consumers; while they are highly concerned for welfare they have significantly lower purchasing frequency even compared to The Indifferent. Finally, Non-Linear Canonical Correlation Analysis (NLCCA) is used to reveal and visually demonstrate the structure of the whole dataset. The analysis demonstrates that concern for animal welfare is not associated with purchase frequency of animal welfare friendly produce when contextual factors are not conducive to doing so. The findings are relevant to a broad audience including industry, policymakers, and academics.


This study was designed to determine the effects of diet supplementation with uncoated lysine (UCL) or coated lysine (CL) to juvenile Jian carp Cyprinus carpio Var. Jian. 330 juvenile Jian carps (initial weight 7.89 ± 0.04 g) were randomly allocated to two groups, feeding a diet containing UCL or a CL for 80 days. Weigh gain, feed intake and feed efficiency ratio were higher in group CL than group UCL, indicating the effect of CL to be better than UCL. Hepatopancreas weight and protein content, intestinal weight, length and protein content, intestinal folds height, activity of intestinal protease, lipase, alkaline phosphatase (AKP), Na+, K+-ATPase were positively affected by CL. Moreover, glutamate-oxaloacetate transaminase (GOT) in muscle, and plasma ammonia, tended to be lower for CL, which means that the improvement of digestive organ development and function may be the possible reason why CL was better than UCL.

Aimed at addressing the vulnerability of anti-corona layer surface to the corona and thermal aging arising out of the uneven distribution of electric field on the large motor stator bar end,this paper describes the numerical calculation of distribution of electric field and loss density of large electric machine by combining the weak form of finite element method with the coupling modeling of multiphysics,and offers the comparison between the proposed method and RC-chain method.The study results show that such algorithm is capable of avoiding the algorithm error revealed by RC-chain method,thus increasing calculation accuracy,and it affords an effective solution to the problem encountered in modeling and defining boundary conditions by conventional finite element method,with a resultant improvement in the solution efficiency and accuracy.Anti-corona layer loss density computation gives the results consistent with heating conditions at corona test.The algorithm,capable of fulfilling the need of three-dimensional electric field calculation of stator end-winding with multi segmental non-linearity corona protective coating,provides not only the theoretical basis for calculating corona structure and material parameters,but also the basis for further designing the optimum calculation model.The algorithm features ideas for the finite element calculation of electric field with surface resistivity.


For powers exceeding a threshold the spectral broadening in fiber amplifiers becomes a significant challenge for the development of high power narrow bandwidth fiber lasers. In this letter, we show that the spectral broadening can be partly caused by four-wave mixing(FWM) process in which the power of the central wavelength would transfer to the side ones. A practical FWM induced spectral broadening theory has been derived from the early works. A numerical model of fiber amplifier has been established and FWM process has been added to the model. During the simulation process, we find that when a 10 GHz, several watts narrow bandwidth laser is seeded into a few modes fiber laser amplifier, the FWM induced spectral broadening effect might continually increase the FWHM of the spectra of the continuum laser to 100 GHz within the amplification process to several hundred watts which has been convinced by our experiments. Some other results have also been analyzed in this paper to complete the four-wave mixing induced spectral broadening theory in fiber amplifiers.


In this work, new silicon-on-low-k substrate (SOLK) MOSFET and germanium-on-low-k substrate (GOLK) MISFET are proposed. SOLK-MOSFET with metal back-gate was successfully fabricated using wafer bonding method with low-k material as an adhesive. It was shown that the threshold voltage, the on-current, and the off-current are more effectively controlled by the back-gate bias voltage in SOLK-MOSFETs with metal back-gate than in SOI-MOSFETs with buried back-gate. Ge MISFETs were fabricated with HfO2 gate dielectric and W/W2N metal gate which are formed on GOI wafer obtained by a new graded Ge condensation method. Excellent drain current-voltage characteristics and subthreshold characteristics in are obtained in the fabricated GOI-MISFETs.


An attempt was made to experimentally investigate the fracture behavior of fiber-reinforced concrete (FRC) by acoustic emission (AE) characterization during direct uniaxial tensile loading. A previous investigation indicated that conventional concrete incorporating short fibers can produce FRC showing a strain-softening response or a strain-hardening response in tension. These two types of FRCs were further investigated using AE techniques, and the results are reported in this paper. A recently developed uniaxial direct tensile test technique was used to conduct tensile test on specimens without notches. AE monitoring was performed during the entire course of each tensile test. Analyses of AE activities and source locations of AE events were performed to study the damage initiation and propagation in the materials. Results show that nucleation of microcracks can be clearly observed for the FRC that shows a nonhardening response similar to concrete without reinforcement. For FRC showing a hardening response, this phenomenon cannot be observed, which indicates that the fibers were effective in blunting the microcrack nucleation.

The microscopic calculation of the decay width of giant monopole resonance (GMR) anticipates the mixing of one-phonon states with configurations of increasing complexity. To this aim we develop the effective approach for description of monopole excited states that are obtained in the quasiparticle random phase approximation (QRPA), with regard of the coupling between one- and two-phonon states. Based on the QRPA one-phonon states, we generate the coupling and two-phonon states by means of the Gaussian orthogonal ensemble (GOE) distribution. Within our approach the spreading width of the GMRs in $^{204,206,208}$Pb are described by means of a random matrix approach on two energy scales. It is demonstrated that the main contribution into the decay of the GMR is determined by a small number of two-phonon states strongly coupled to low-energy surface vibrations. While a vast majority of the coupling matrix elements (that are small in value and following the GOE distribution) are responsible for the fine structure of the GMR spreading width. A remarkable agreement between the results of the full microscopic calculations (based on QRPA phonons coupled by means of the microscopic coupling matrix elements with calculated two-phonon states) with those of the developed approach confirms the vitality of the proposed ideas.


In this research, the electrochemical oxidation of 4-amino phenol (1) was studied by cyclic voltammetry and controlled potential coulometryin in the absence and presence of 2-mercaptobenzimidazole (3a), 2-mercapto-5-methyl benzimidazole (3b) and 2-mercapto-5-metoxy benzimidazole (3c) in aqueous/ethanol (70/30 v/v) mixture.The results revealed that p-quinone(2) derived from oxidation of 4-amino phenol (1) participate in Michaeladdition reactions with 3a-c via EC mechanism. To confirm the proposed mechanism, the electrochemical synthesis of 4-amino phenol (1) was performed in the presence of 2-mercapto benzimidazoles (3a-c), and the obtained products were identified by 1HNMR, FTIR and Mass spectroscopy. In this study, we synthesized a variety of products with good efficiency using controlled potential electrochemical oxidation at a surface of graphite electrode.

Abstract Cell decompositions are constructed for polynomials f ( x )∈ Z p [ x ] of degree n , such that n p , using O ( n 2 ) cells. When f is square-free this yields a polynomial-time algorithm for counting and approximating roots in Z p . These results extend to give a polynomial-time algorithm in the bit model for f ∈ Z [ x ].


We explore the close environment of active star-forming galaxies (ASF) in the 2dF. We find ASF galaxies to be the most likely population to inhabit extremely close pairs located in low density regions. In addition, we find that ASF galaxies in these pairs are almost entirely concentrated in the -20 < M_B < -19 magnitude range.

Reading Cornelia H. Dayton and Lisa Levenstein's essay on the last decade of scholarship in the now forty-year evolution of a field, I am struck by the choices that the authors have made. They are good choices, perhaps the only reasonable choices within which to organize an increasingly complex literature, and they have enabled Dayton and Levenstein to smoothly and generously incorporate an astonishing array of literature. For this we should all be grateful. I am happy to have my attention drawn to the new and exciting work they describe. And yet, from my perspective on the other side of the generational divide, I find the organizational categories limiting. Let me try in this short response to explain why. Dayton and Levenstein offer two trajectories in their piece. The first defines gender in terms of identity and pays special attention to issues of sexuality and the body. The second offers to link recent scholarship to mainstream narratives of U.S. history. In doing so, it shifts the definition of gender from identity to process and evokes a literature that speaks to a more traditional subject matter. The authors are quite right to note that differences in approach have not been divisive among historians, and yet if our usages of notions of gender have changed sufficiently to produce the rich literature the authors describe, it is worth noting their implications. Sharpening our understanding of the uses of gender might help us think a bit more about where the field will move in the future. As women's history emerged from its celebratory mode in the 1970s to try to comprehend how men and women functioned inside what Gayle Rubin called a gender system, gender came to be understood as a process. Like class, it came to be seen not as a fixed set of circumstances but as a changing set of relationships intrinsic to particular visions of social order as they emerged at different times in different societies. As such, gender became a vehicle for exploring the distribution of power in society at large. In revealing something of how power was ordered and perpetuated, gender became crucial to comprehending social structure and social change. The more we understood of how gender operated, the more we would understand about hierarchies of domination as they functioned to

This study presents the trade-off between probability of spectrum hole utilisation (PSHU) and sensing time duration of secondary user (SU) in cognitive radio networks. On the basis of the analytical formulations of PSHU, it is shown that there exist an optimal sensing time duration and the optimal length of time frame for a given mean idle time of primary user (PU). Unlike the existing works, a frame structure of SUs with a fixed length of time frames is considered. The effect of both sensing and transmission time of SUs over PSHU is considered simultaneously. As increasing sensing time duration to improve the probability of detection for PU's presence or absence leads to a reduction in transmission time, which may further decrease PSHU. The numerical and simulation results show that using the optimal sensing time duration (which leads toward the optimal reduction in transmission time) and the optimal length of time frame provides the maximum PSHU.

T success of any garden begins with the soil. A fertile, biologically active soil provides plants with enough nutrients for good growth. Fertilizers supplement or renew these nutrients, but they should be added only when a soil test indicates the levels of available nutrients in the soil are inadequate. In the garden, whether you are growing annuals or perennials, vegetables or flowers, most of the crops have a few short months to grow and develop flowers and fruits. The soil must provide a steady, uninterrupted supply of readily available nutrients for maximum plant growth. Fertilizer form, particle size, solubility, and potential uptake are extremely important in fertility programs for gardening. Organic gardeners place great emphasis on using natural minerals and organic fertilizers rather than manufactured ones in order to build their soil. If you use organic materials as all or part of your fertilization program, this bulletin will help you calculate the proper amount to use from the guidelines recommended by a soil test. Most organic materials must be used in combination since many do not have a balance of N-P-K; you should become familiar with the attached list of fertility values of organic sources of nutrients (Table 1, page 4).


: With the development of pragmatics, there are more and more researches on humor from the perspective of cooperative principle. Many researchers have made extensive research on the verbal humor of various sitcoms from the perspective of violating the cooperative principle, but there is little research on the work The Neighborhood. Humorous language is the soul of sitcom. Therefore, it is valuable to study verbal humor in sitcoms from the perspective of violating cooperative principle. This study uses the qualitative method to analyze the verbal humor of the American sitcom The Neighborhood, and explores the process of the characters' violation of the cooperative principle to produce humor, as well as their understanding of the inherent laws of humor. It explains how the characters violate the four principles of cooperation in different ways to achieve verbal humor. The results show that the main reasons for violating the cooperative principle to achieve humorous effects are: covering up the facts, avoiding embarrassment, sarcasm, changing the topic and so on.

Camponotus sericeiventris is a wood-harvester ant that occurs in several habitats of the Neotropical region. It has large colonies that are established in large trees, live or dead. However, there are no studies on the ecology fo this species in natural areas. This study had the objective of determining the size and species of trees that harbors colonies of this ant species, its daily schedule of activities and its relation with leaf-cutter ants. Most nests were found in live trees (90.7% of the nests found) with a mean circumference of 62.56 cm. Plant abundance did not explain the greater number of nests found in certain tree species. Miconia albicans is the most abundant tree species in the study area, but no nest C. sericeiventris was found in this species. The results suggest that tree size may be an important factor in nesting site selection. There was a positive correlation between plant size and number of nests for Vochysia tucanorum (r = 0.644; p < 0,001). Therefore, nesting selection by C. sericeiventris is in part determined by plant size. Several events of agonistic interaction between C. sericeiventris andf leafcutter ants were observed.


The presence of daily growth increments in otoliths was validated for Anguilla rostrata. Elvers were captured at the freshwater–seawater interface of the Annaquatucket River, Rhode Island, immersed in a tetracycline hydrochloride solution to mark their otoliths, and maintained in stream aquaria for 10 or 20 d. Increment counts outside the tetracycline mark generally underestimated the number of days since marking by less than 5%. This underestimation was probably due to the time required for tetracycline incorporation after administration.


The theological-political view is a possibility of dealing with Thomas Hobbes's theoretical proposal. This approach consists, synthetically, of holding that key political concepts are understood by means of theological concepts. This viewpoint, we believe, brings a new dimension to the works of the English philosopher, and also questions the concept of modern secularization. On the other hand, it is not risky to maintain that the Apostle Paul Letter to the Romans delivers a number of theological notions that have

The pruning of branches in loquat trees is the main part of the consumption of labor in production, so the use of branch intelligent pruning device can effectively reduce the labor intensity and cost. Identification of branches is the key technology of intelligent pruning branches, and it is the first step of intelligent pruning equipment research. A recognition method of branch images was introduced in this paper. With this approach, we used open operation to deal with the images after the segmentation which was performed by using color aberration, and the image noises were eliminated basing on comparison of connected areas. For faulted branches which were caused by leaves shield or strong illumination, they could be filled by expanding at the designated place, and then the integrated frameworks of branch images were obtained. At last, both the positions of the center points and the diameters of loquat branch images were determined based on the characteristics of the branch image edges. Experiments showed that the accurate identification rate of branch feature images and branch center coordinates were 89.3% and 84.6%.

A review is given of the electronic specific heat vs. electron concentiation for b.c.c. solid solutions, including new data for the systems V-Cr and Ti-V. The latter alloys show a maximum of gamma at approximately 60% V. The electronic specific heat coefficients correlate well with the superconductive transition temperatures, according to the Bardeen-Cooper-Schriffer theory, with an interaction coefficient V independent of composition. It was found that the CsCl-type ordered alloys in the ternary TiFe-TiCo and TiCo-TiNi systems possess electronic specific heat values paralleling those for the b.c.c. Cr-Fe alloys at the same average electron concentrations. The electronic specific heat values for the b.c.c. alloys of transition elements with one another can be apparently described to a surprising extent in terms of a more or less rigid band, the degree of filling up of this band with electrons being determined essentially by the average electron concentration for the alloy. This appears to hold even in cases uhere the electron concentration is determined by averaging over three different atomic species. As found also for the alloy VFe. with a CsCl-type ordered structure, ordering causes little, it any, change in the electronic specific heat values of these alloys. New low temperature specific heatmore » measurements with f.c.c. solid solutions in the Mn-Fe, Mn-Ni, Fe-Ni, V-Ni systems gave coefficients for the specific heat term linear in temperature, which are in some cases quite inconsistent with each other if interpreted as electronic specific heat coefficients. Consistent gamma values were obtained for simple ferromagnetic alloys and for nonmagnetic alloys. For alloys where the simultaneous presence of both ferromagnetic and antiferromagnetic interactions is known from magnetic measurements, or may be considered as very likely, the measured gamma values are anomalously high. It has been proposed by Marshall that a temperature-linear contribution to the low temperature specific heat can arise in instances where a sufficient number of spins are located in a near zero magnetic field. It appears from the results that this condition is often fulfilled in alloys having both ferromagnetic and antiferromagnetic interactions. As a result, in such cases the gamma value measured at low temperatures comprises, in addition to the true electronic specific heat coefficient, also a magnetic component. Using only gamma values obtained for simple ferromagnetic and for norrnagnetic alloys, the shape of the d-band for the f.c.c. solid solutions has been nevertheless successfully determined in the electron concentration range from approximately 8 to 1O.

This paper focus on the relationship between the right's aims of providing an incentive for creative activities, and the overall efficiency. It can in fact be shown that, even if the commodification of intellectual works by means of copyright does provide some incentive for creative activities, this benefit is offset by certain 'side effects' on the diversity and quality of the ideas produced, and interference with access to information and the incremental process of creation. All of which, if duly taken into account, can seriously call into question the overall balance of efficiency. In the present-day debate, the justifications given for copyright and author's rights invoke both considerations of economic efficiency, as well as ethics and rhetoric. However such arguments neglect to factor in the social costs, thus portraying in false light an institution that has, in practice, often served private interests very distant from its purported aims, injecting a significant amount of inefficiency into the economic system. This state of affairs can therefore be aptly summed up by the Latin adage of the title: "A wolf often lies concealed in the skin of a lamb". Nevertheless, the objections raised thus far, in the literature on the economic analysis of intellectual property rights, have inevitably resorted to the contra position of extra-economic values, such as equity and justice, against those of economic efficiency. In the present discussion we shall seek to reconcile these two sides, showing how, under an expanded analytical perspective with respect to costs and benefits, and taking into consideration additional elements, copyright proves to be fundamentally inefficient even from a strictly economic standpoint, and that this will only be aggravated by technological progress. We will therefore demonstrate that an examination of the dynamics of the right within the market and society can seriously call into question, or even entirely overturn, the traditional economic arguments in favour of copyright.


This article studies the reconciliatory potential of history education in post-conflict societies. History education today is understood through post-colonial, multiperspectival studies, which in a post-conflict society contribute to reconciliation by fostering critical thinking, being inclusive in regard to different social groups, and recognising the local, vernacular history culture. The article compares three cases of post-conflict history education, derived from Finland, Bosnia-Herzegovina and South Africa. It concludes by considering the nature of feasible teaching processes and the role of different educational actors.


In this paper, we study a compute-and-forward (CAF) relaying scheme with low-density parity-check (LDPC) codes, a special case of physical layer network coding, under the quadrature phase shift keying (QPSK) modulation. The novelty of this paper is the theoretical analysis of decoding performance of the CAF scheme and traditional separation decoding (SD) scheme with joint decoding or with successive interference cancellation (SIC) decoding when the reception powers from both senders are not equal but close to each other. First, we study the decoding performance of linear random coding (LRC) in the CAF scheme whose decoder is based on the degraded channel. When rotation angles of constellations of two senders are controlled, we show that they can achieve rates well beyond the multiple access channel (MAC) with LRC with optimal rotation angles. Second, we analyze the practical feasibility of CAF using LDPC codes in terms of computational costs and decoding performance of belief propagation (BP) decoders. The calculation complexity of the BP decoder for the CAF scheme is almost equal to that of the SIC BP decoder, and smaller than the joint BP decoder in the SD scheme. Decoding performance is evaluated by the asymptotic decodable region using density evolution. The results show that, with code rate fixed, the CAF scheme has better performance than the SD scheme with joint BP decoding and SIC BP decoding in the high rate region.


This paper addresses a novel lifelong learning (LL)-based optimal output tracking control of uncertain non-linear affine discrete-time systems (DT) with state constraints. First, to deal with optimal tracking and reduce the steady state error, a novel augmented system, including tracking error and its integral value and desired trajectory, is proposed. To guarantee safety, an asymmetric barrier function (BF) is incorporated into the utility function to keep the tracking error in a safe region. Then, an adaptive neural network (NN) observer is employed to estimate the state vector and the control input matrix of the uncertain nonlinear system. Next, an NN-based actor-critic framework is utilized to estimate the optimal control input and the value function by using the estimated state vector and control coefficient matrix. To achieve LL for a multitask environment in order to avoid the catastrophic forgetting issue, the exponential weight velocity attenuation (EWVA) scheme is integrated into the critic update law. Finally, the proposed tracker is applied to a safe cargo/ crew transfer from a large cargo ship to a lighter surface effect ship (SES) in severe sea conditions.


Energy consumption and the comfort of occupants are two import issues in office buildings. Various intelligent agent systems and other technologies thus have been proposed to co-ordinate these two issues in office buildings. However, none of these tools are effective. One possible reason is that these tools were developed based on the existing thermal comfort equation, which assumes that all occupants share the same comfortable skin temperature when performing the same activity. This assumption is questionable. In this study, a personalized thermal comfort equation is therefore proposed. Based on the personalized thermal comfort equation, an intelligent thermal comfort agent control system is proposed to optimize energy consumption and occupants comfort in office buildings.


This essay explores Robert Zemeckis's Beowulf (2007) as a contemporary retelling of the Anglo-Saxon poem which has been influenced by both postmodern culture and post 9–11 philosophies. In this contemporary iteration, the figures and narratives of the hero, the monster, and their culture are radically destabilized and fragmented. These permeable and broken bodies offer insight about contemporary culture, as well as the originating Anglo-Saxon culture.


We use aggregate Schedule M-3 tax return data from Subchapter C corporations to provide descriptive evidence on book-tax differences from 2004 to 2013. Across the sample period, our primary findings are: (1) total book-tax differences increase, (2) a substantial amount of book-tax differences are explained by firms' operations and financing, as well as economic incentives, (3) firms report a substantial but decreasing amount of book-tax differences in the "other" categories, (4) the frequency and magnitude of reportable transactions decreases significantly, and (5) foreign earnings and repatriations increase. However, the relative amount of foreign earnings repatriated decreases substantially after 2009.

This paper sought to unravel the contemporary views on Filipino woman through speech and though presentation using Magnificence written by Estrella Alfon. Speech and thought presentation is primarily concerned as to how a writer reveals the speech and thought of their characters as they interact with other characters in the literary work. As literature remains a reflection of the society, speech and thought presentation gave way to the perception of how a Filipino woman is now seen in the society. The analysis revealed the following views: an unconventional woman as a mother; an equal partner; and a 'magnificent' and headstrong woman. As these contemporary views on Filipino were explored, an acceptance to more progressive perspective on the Filipino women will most likely emerge in the future.


A semi-empirical statistical physics model for the dynamical behavior of stock prices in Sri Lankan financial market was analyzed. In this model, the time evolution of a collective set of stock prices was analyzed using the Hamiltonian of a nearest neighbor Ising model. Monte Carlo simulations were performed and resultant stylized features of the corresponding system were discussed.


Summary: Results of double‐blind, placebo‐controlled, add‐on trials of topiramate (TPM), lamotrigine (LTG), and vigabatrin (VGB) in refractory partial epilepsy were reviewed. In three European multicenter studies of TPM, the clinical efficacy of 400–, 600–, and 800‐mg/day target dosages was demonstrated. In a similarly designed United States trial, LTG was significantly superior to placebo at a 500‐mg/day dosage but not at a 300‐mg/day dosage. A meta‐analysis of a number of smaller trials of VGB suggests that a ≥50% reduction in seizures is observed in approximately 45% of patients with refractory partial epilepsy. All of these newer antiepileptic drugs have shown efficacy in well‐controlled trials and should contribute significantly to our ability to manage partial epilepsy.

The effect of blue light (400–500 nm) removal on the morphology and pigmentation of evergreen Pinus sylvestris seedlings of northern (67°N) and southern (62°N) origins, deciduous Betula pubescens spp. czerepanovii and B. pubescens f. rubra seedlings, and herbaceous Epilobium angustifolium and Glechoma hederacea plants was studied. The plants were grown at the latitude 69°N. The blue wavelengths were removed from sunlight by orange plexiglass chambers. The results suggest that the northern origin Pinus sylvestris seedlings are more sensitive to blue light as compared with the southern origin seedlings. The changes in the morphology of shade-intolerant Pinus sylvestris, both Betula seedlings and Epilobium angustifolium were similar and more pronounced under blue light depletion, as compared with the more shade-tolerant Glechoma hederacea. This indicates that the morphological responses of shade-intolerant species to blue light depletion are quite conservative across life forms.


Purpose: Pediatricians play a crucial role in counseling the families of children with developmental disabilities such as autism spectrum disorders (ASDs), intellectual disability (ID), and developmental delay (DD). Parental perceptions about the causes of these conditions may influence their decisions about a range of health-related behaviors, including family planning, vaccination, and treatment choices. Understanding the factors that influence parental etiologic beliefs may enable pediatricians to provide more effective guidance to these families. Thus, the aim of this study was to identify clinical correlates of etiologic beliefs in a …

This article will discuss a two-category image classification which has been performed on a joint transform correlator (JTC) by using the Kittler-Young transform. The property of optimally utilizing the class means and variances in the Kittler-Young transform has enabled a high space-bandwidth-product operation. The digitizing effect of the liquid crystal television has been utilized to increase the correlation peaks.


The problem of dynamic Quality of Service (QoS) management for multimedia services has been addressed from two complementary, yet interrelated directions; one mainly dealing with designing adaptive or "elastic" services, and the other, dealing with "smarter" resource allocation. We adopt this approach in this paper, by performing a graceful quality degradation and the corresponding resource (re)allocation for multiple multimedia sessions in case of decreasing network resources. We introduce a mathematical model which optimizes overall system utility by taking user satisfaction and operator profit into account.


Application of Phasor Measurements Unit (PMU) in system monitoring and control has been receiving enormous attention in the power system industry nowadays. The availability of real-time synchronized phasor measurements offers unparalleled opportunities to expand the visibility of control centers and improve system reliability Utilities have taken important steps to incorporate PMU s into the key and critical load centers, and the output of the PMUs are used as an input parameter to special voltage protection and control schemes. The focus of this paper is on the recent work accomplished in the area of voltage monitoring and control by utilization of synchronized measurements received from PMU on the heavily loaded and critical bus.

Recently, with the development of the Transformer, re-identification (ReID) has great success in various applications. Existing works prefer to utilize the Transformer's highest-level information as its discriminative feature, which focuses on a few concentrated parts or areas. However, in ReID filed, under such various scenes and camera views, only using a few concentrated parts to distinguish the query person is insufficient. Meanwhile, we find that Transformer's lower-level information is also helpful for the recognition accuracy of the query person, especially, when the scene changes greatly. Therefore, we propose a Multi-level Feature Aggregated Transformer for person re-identification (MFAT) with high performance. To aggregate multi-level information, two novel modules are carefully designed. (i) The Global Content and Structure Aggregation (GCSA) module is proposed to aggregate multi-level information in a global manner. (ii) The Local Convolution Aggregation (LCA) module which consists of a series of convolutional blocks, is introduced to aggregate multi-level features with local operations. To the best of our knowledge, this is the first work to aggregate multi-level features with a Transformer backbone for person ReID task. Experiment results show that our method has achieved state-of-the-art on three person ReID benchmarks, with both Pyramid Vision Transformer (PVT) and Vision Transformer (ViT) backbones.

Purpose: To determine the phenolic constituents as well as anti-proliferative, antioxidant and ironchelating activities of the leaf and rhizome extracts of Phymatopteris triloba. Methods: Concentrations of selected hydroxybenzoic acids, hydroxycinnamic acids and flavonoids in aqueous extracts were quantified using high performance liquid chromatography (HPLC). Antiproliferative activity was assessed on human cervix cancer cell line (HeLa) and human chronic myelogenous leukemia cell line (K562). Superoxide and nitric oxide scavenging activities as well as iron-chelating activity were determined colorimetrically. Results: Protocatechuic acid content of the rhizome extract (154.7 g/g dry matter (DM)) was 1.9-fold higher than in the leaf extract. p-Hydroxybenzoic acid (34.6 g/g DM) and gallic acid (18.9 g/g DM), were only detected in the rhizome extract. Sinapic acid (6.6 g/g DM) was detected in the leaf extract only. Myricetin content of leaf extract (98.5 g/g DM) was 3.7-fold higher compared with the rhizome extract. At 500 g DM/ml, both extracts produced about 40 and 30 % anti-proliferative activity on HeLa cells and K562 cells, respectively. Both extracts had moderate nitric oxide-scavenging and ironchelating activities. The leaf extract half-maximal effective concentration (EC50) value of 0.85 mg/ml (scavenging of superoxide radicals) was higher than that of ascorbic acid. Conclusion: P. triloba is a potential source of anti-proliferative, antioxidant and iron-chelating agents. Its bioactivities may be attributed to the presence of phenolic constituents.


Biogas plant has been seen as one of the most popular and environmentally friendly strategies for tackling with climate change and improving livelihood of people in developing countries. However, the financial feasibility of establishing in the rural and low income communities is the major issue. A survey research was conducted to study the feasibility of biogas plant installation in Chitwan district of Nepal. Altogether 120 households, 60 from Gitanagar and 60 from Patihani were selected using the simple random sampling technique comprising 30 adopters and 30 non adopters of biogas from each VDC. The primary information was collected from face to face semi structured interview schedule. The secondary data related to the climatic pattern, trends were obtained from different publication and journals. The study related to the economic feasibility of the biogas revealed that the biogas was an alternative household energy source in the study area which had significant impact on the reduction of mosquito breeding, flies and rodents, foul odor, and smoke. The amount of the firewood consumption had drastically decreased from about the 2 quintal to 60 kg per month. The result from the Benefit–Cost Ratio was 1.62 at 14% rate of discount. The NPV was found to be Rs. 128113.10; IRR was 54.67%, Pay Back Period of 3 years signifying that the installation of the biogas was economically viable. Hence, the biogas may have multiple functions in the mitigation, adaptation as well as environmental and economic empowerment of the vulnerable section of the population in the country.

Lithium nitroxide has been formed through reaction of lithium atoms and nitric oxide in solid argon at high dilution. Isotopic substitutions at all atomic positions verify the molecular identity and furnish an ample basis for normal‐coordinate analysis. The data indicate the molecule is bent (100°±10°), and they favor the molecular formula LiON (rather than LiNO). Potential constants kNO=7.97 mdyn/A, kLiO=1.33 mdyn/A, kα=0.54 mdyn·A/rad2, and kLiO,α=0.39 mdyn are obtained. The force constants can be correlated to those of other molecules with the aid of the electronegativity of lithium. The bonding is not readily explained; the NO bond has a bond order near 1.7, significantly weaker than that in HNO.


Detection thresholds for sinusoidally amplitude modulated noise were measured across modulation frequency for listeners suffering (1) chronic Meniere's disease and (2) acoustic neuroma. The average Meniere's thresholds were similar to normal thresholds through 60 Hz, at higher modulation frequencies sensitivity declined at approximately twice the normal rate [(—)6 dB/oct vs (—)3 dB/oct]. The Meniere's data can be described well by the mathematical representation for a low‐pass filter with a cutoff frequency of 60 Hz. The neuroma patients exhibited a general reduction in sensitivity to modulation and also a lower cutoff frequency, approximately half the normal value. Meniere's thresholds may be explained by poor frequency selectivity due to hydrops. The neuroma thresholds reflect: (1) hearing loss at higher audiometric frequencies, those frequencies most important for optimum modulation detection and (2) secondarily, the direct effect of the tumor, which disrupts low‐frequency modulation detection. One may presumably account for these findings by: (1) broadening of the predetection filter (in Meniere's disease) and (2) lowering the cutoff frequency of the low‐pass filter (in acoustic neuroma) in Viemeister's [J. Acoust. Soc. Am. 66, 1364–1380 (1979)] envelope detector scheme. Paradoxical SISI phenomena will be discussed in terms of these findings and Viemeister's model.

Schools are not just four walls inside of which students learn how to read, write and think. Schools provide a venue where young people meet each other, and where they develop relationships and friendships that may last for decades. At school, students socialise and hone the interpersonal skills that are required to function effectively in the workplace and in society at large.
Employers value such skills more now than ever before: wages have risen more for jobs that demand a high level of social skills than for jobs that require only a low level of social skills. But until now, there was no measure of students' ability to work together that was consistent across countries. PISA changed that when it introduced its collaborative problem-solving assessment in 2015, which, more specifically, measured students' ability to work together to solve problems and achieve goals.

In this work we are interested in the general problem of the determination of the normed division algebras. Our fundamental results are obtained in the particular subclass of those 8-dimensional quadratic flexible real division algebras.
We give a new process which generalizes that of Cayley-Dickson and which allows the obtaining of a new family of eight-dimensional quadratic flexible real division algebras. We give examples of 8-dimensional quadratic flexible real division algebras which cannot be obtained by this first process of duplication and by means of a second process, which consists in making an appropriate deformation of the product of the octonion algebra, we determine these last ones and we resolve the isomorphism problem. Among the eight-dimensional quadratic flexible real division algebras, we study those which possess a nontrivial derivation by mean of the generalized Cayley-Dickson process. We also give examples where the group of automorphisms is trivial, and characterize the algebras whose group of automorphisms is not trivial. This brings to light the unlimitedness of this subclass of algebras.
