Objective: to define forms and the directions of social and responsible activity of regional business. In article approaches to definition of social responsibility of business are considered. It is established that now there is no uniform idea of essence of social responsibility of business. The relation to social responsibility of the Russian business community is revealed. It is defined that social responsibility includes complex responsibility of the business partner, the employer, the citizen and the participant of the social relations. The directions of development of social responsibility of the regional enterprises, possibilities of their participation in social development of the region are defined. Examples of activity of the regional enterprises for various directions are given: care of improvement of working conditions and social wellbeing of workers; participation in maintenance of wellbeing of society through charity concerning orphans, disabled people and other socially vulnerable groups of the population; aspiration to improve the territory in which the enterprise is located; maintaining joint projects with local administration and other activity. Experience of successful interaction of business and the regional power on development of socially responsible activity of the enterprises is considered. The conclusion that priority activities for the Tambov business there are care of the staff, of development of local community and responsibility before public authorities is drawn.

HISTORY Dramatic changes in the structure and function of the family in modern industrialized societies have been noted throughout the literature on the sociology of the family. Burgess, Locke, and Thomas suggest that the very nature of the family has been radically transformed. In their words, "The family has been in transition from an institution, with family behavior controlled by the mores, public opinion, and law, to companionship, with behavior arising from the mutual affection, equality, and consensus of its members"(1963 vii), This change in the nature of the family has had an impact on the ways in which couples define marital satisfaction. Moreover, the methods utilized to deal with marriages that are to some degree in jeopardy have paralleled the changing nature of the family. Thus there appears to have been a fundmental shift in the bases for determining marita.l satisfaction. In preindustrial societies of the past, marriage and family· were primary social institutions; the whole society revolved round the family. If society were to function, the family must function as an institution. Marital satisfaction involved macro-sociological issues. The interpersonal .subjective dimension to marriages of the past was always subordinate to the functional dimension of marriage (Ragula 1975). In modern times, marital satisfaction has become more subjective in definition. Marriage and family life in general in the 1960s and 1970s has become more an interactional network rather than an institutionalized set of roles. Roles within the modern family seem to be emerging attitudes toward family life and sex roles. Marital satisfaction is no longer based only on whether or not roles are performed but also involves the notion that interpersonal needs are central to a good marital relationship. One facet of the interaction process that has come under increasing examination. is the degree of communication between the members of the family. To enrich the quality and quantity of communication is a prime topic of concern for both researchers and practitioners in family therapy. This general topic has been called marriage enrichment. Its primary purpose has been to make good marriages better (Mace, 1979). By far, the most popular of the enrichment programs has been the marriage encounter which was first developed in Spain by Gabrel Calvo S.J., with the help of the French depth psychologist, Paul Toumier (Bosco, 1973). Calvo brought the program to the United States and, with the help OfChuck Gallagher S.J., the program spread throughout the majorcities in the.Iate 1960s. However, the program split into two movements in 197:5Worldwide Marriage Encounter and International Marriage Encounter(Genovese, 1975). We will addresses the Worldwide Marriage Encounter (WME) program. WME is an attempt to enrich the marital relationship through having the partners experience new ways of relating to each other. The program encourages the sharil"lg of feelings in dialogue during the. weekend "retreat" (Otto, 1975). Through .the dialogue~ the colJple is expected to beQOme closer and more satisfied in their relationship (Gallagher,1975). As with marriage counseling, there have been very divergent evaluations of the typical outcomes of WME programs. "Overall, there are indications that enrichment programs can bring about immediate positive change in some aspects of· the relationship· (Smith, Scott, and Schoffner, 1976). However, even this somewhat bia.sed view.in fayor of marriage enrichment admits that there is a need for more empirical stl.ldiesto determine the effectiveness of marriage encounter programs.


I In March 1964, in New York Times v. Sullivan,' the Supreme Court of the United States adopted the "Meiklejohn interpretation of the First Amendment." Professor Alexander Meiklejohn viewed the First Amendment as a necessary predicate to the right to vote, the "external expression" of the self-governing activities of the people.2 Three weeks before its decision in New York Times v. Sullivan, the Court in its first major substantive reapportionment case, Wesberry v. Sanders, had described the fundamental status of the right to vote in these terms:3 "No right is more precious in a free country than that of having a choice in the election of those who make the laws under which, as good citizens, we


Annett (2001) has made an in-depth critique of subjectivity in science, concentrating not only on those rating scales which are extensively used in ergonomics, but also the very philosophy of subjectivism itself. The present authors take this critique and use it to reappraise their own interpretation of mental workload, a key concept popularly assessed by subjective measurement. Having recently proposed a definition of mental workload (Young & Stanton, 2001), the present commentary considers deeper problems of subjectivity in the interpretation, perception, and measurement of mental workload. It is realised that there are fundamental problems inherent with such a subjective concept, particularly concerned with the dependence on context and lack of an absolute metric. However, it is also noted that the very point of ergonomics is to address contextual influences on human performance. Therefore, in the absence of a complete paradigm shift in ergonomics, the discipline will have to either accept or find ways of coping with the problems of subjectivity. Young, M. S. & Stanton, N. A. (2002). It's all relative: defining mental workload in the light of Annett's paper. Ergonomics, 45(14), 1018-1020. It's all relative: Defining mental workload in the light of Annett (2001) On the basis of a comprehensive literature review, Young & Stanton (2001) arrived at the following definition of mental workload (MWL): "The mental workload of a task represents the level of attentional resources required to meet both objective and subjective performance criteria, which may be mediated by task demands, external support, and past experience." (p. 507) The definition was offered for a construct which had previously evaded having its meaning pinned down. However, it was just an offering, and by no means argued as the ultimate formalisation of MWL. Indeed, it was Young & Stanton's (2001) own understanding of the available literature which led them to suggest the definition. Now, in the light of Annett's (2001) article, it seems there are three cans of subjective worms associated with it. The first is the problem of interpretation. The authors had their own backgrounds and knowledge bases serving as (albeit possibly implicit) frames of reference and agendas for the review. Being researchers in cognitive ergonomics, it is unsurprising that their definition was couched in terms of attention and performance. This does not necessarily mean such an approach was right or wrong – any expert in the arena would undoubtedly have done a similar thing. A stress researcher would have reviewed the stress literature and defined MWL in terms of stress reactions. Whether or not Young & Stanton's Young, M. S. & Stanton, N. A. (2002). It's all relative: defining mental workload in the light of Annett's paper. Ergonomics, 45(14), 1018-1020. (2001) definition becomes accepted depends on the extent to which other researchers in the area agree with it, which in turn depends on the degree of overlap between their interests. This cuts to the heart of the intersubjectivity issue to which Annett (2001) refers, only at a more macro level: "Progress in science depends on the degree of shared meaning between individuals concerning their observations and experiences." (this issue). Annett argues that intersubjectivity is crucial for laboratory measurements to be valid. However, it is just as vital amongst those scientists making the measurements to agree on the concepts they are measuring. Science (with a capital "S") is, after all, a belief system, itself governed by the vagaries of subjective interpretation. Just like any other belief system, there has to be a certain leap of faith to accept some of the concepts and theories. Secondly, Young & Stanton (2001) introduce subjectivity into the definition by allowing MWL to be influenced by the internal goals of the individual. This is where the definition gets quite knotty, since these goals will vary between individuals and across situations. With such a context-specific construct, one might argue whether a definition is of any practical use at all. To illustrate this, take the perception of time. Our definitions of time – seconds, minutes, hours, and even months – are largely arbitrary, and would be of little use if we were spending our lives on another planet. However, for all intents and purposes, the 24-hour day is sufficient, since there are few people concerned with measuring time relative to different planetary orbits or rotations. So, specific to the context of Earth, our definition of time is useful. But outside that context it begins to lose its practicality and even its 'absoluteness' – time can even be affected by Young, M. S. & Stanton, N. A. (2002). It's all relative: defining mental workload in the light of Annett's paper. Ergonomics, 45(14), 1018-1020. altitude, speed, or relative direction (cesium clocks have been shown to lose time when travelling eastwards, and gain time westwards). The same goes for MWL, but the context scale is much smaller – rather than planet to planet, it changes from person to person. If the meaning of MWL for a given person in a particular situation is different from that for another person in a different situation (or even the same person in a different situation etc.), defining it in these terms seemingly has as much use as an atomic clock on Jupiter. The Science of Ergonomics, though, is all about context. As Tom Stewart observed at this year's Ergonomics Society Lecture, every good ergonomist will tell you that human performance depends on its context. Predictions, therefore, can only be made with reference to that context, so by implication, all of our theories must be context-specific. Finally, there is the complex issue of MWL measurement. Many authors claim that the use of subjective ratings may well be the only index of 'true' MWL (e.g., Hart & Staveland, 1988). Subjective MWL scores have been shown to be sensitive to perceived difficulty (Liu & Wickens, 1994) and demand for multiple resources (Hockey, Briner, Tattersall & Wiethoff, 1989). One particular advantage with subjective measures is that they are sensitive to changes in effort, when such effort maintains primary task performance at stable levels (Hockey et al., 1989). One of the hurdles in deriving a subjective measure of MWL is validating it by correlation with other measures (such as physiological evidence) or against objective demand. Annett (2001) suggests the method of cross-modal matching to quantify Young, M. S. & Stanton, N. A. (2002). It's all relative: defining mental workload in the light of Annett's paper. Ergonomics, 45(14), 1018-1020. psychometric scales, and perhaps descriptors of weight (e.g., this task is 'heavy', 'light' etc.) would provide an adequate analogy for MWL. But this raises the question of whether there is such a thing as 'objective demand', or whether – especially in a field trying to improve design – it is simply what people perceive that is important. If the latter is the case, it will mean there is no need for the use of an anchor task to calibrate subjective scales. Criticisms of subjective measurement techniques are primarily concerned with the metacognitive abilities of the operator (Petrusic & Cloutier, 1992; Praetorius & Duncan, 1988). That is, given the fact that the measures are necessarily administered post-task, one might question the reliability of self-reports, particularly for long task durations. A recent attempt to develop an instantaneous (i.e., 'on-line') measure of subjective MWL met with limited success (Tattersall & Foord, 1996). Unfortunately, whilst it correlated with other measures of workload, it was disruptive to the primary task. These effects are further complicated by a Heisenberg-esque uncertainty principle – that the act of measurement itself is also demanding, so may influence MWL ratings. In exploring a philosophical view of MWL, then, it would seem that the many problems of definition and measurement are down to the subjective nature of the beast. Whether it is the measurement, the experience, or even the very Science of MWL, there really is no absolute truth, only perceptions of truth. Hardly anyone would argue against the existence of such a thing as MWL, though, since we all experience it frequently. But the fact that it means different things to different people at different times causes problems Young, M. S. & Stanton, N. A. (2002). It's all relative: defining mental workload in the light of Annett's paper. Ergonomics, 45(14), 1018-1020. for applied research. How are we supposed to design a system for "optimal MWL" when such a state will probably only exist for an infinitesimally brief period of time? As every good ergonomist will tell you, "It's all relative", as context is definitely the current zeitgeist in Ergonomics. Unless a better paradigm emerges, we will have to find ways of working within it. Perhaps the key will be to draw up a list of "mindspace" tables to design for cognitive ergonomics, just like the Bodyspace data for physical ergonomics (Pheasant, 1986). With such data, the logical positivist approach to MWL research (which we in particular have taken in our laboratory) could be justified as more science than art.


Diabetes is a group of metabolic diseases resulting from defects in insulin secretion, insulin action, or both and is characterized by hyperglycemia. The chronic hyperglycemia of diabetes is associated with long-term damage, dysfunction, and failure of different organs, especially the eyes, kidneys, nerves, heart, and blood vessels. The prevalence of diabetes mellitus (DM) is growing rapidly worldwide and is reaching epidemic proportions. This article briefly deals with the medical aspects of DM, its oral manifestations and orthodontic treatment considerations.


The properties of materials have a close connection to their crystal structures. Rare earth (R)-transition metal (T) rich compound are the focus of investigation in the search for new hard magnetic materials. As the basis for the study of stabilized effect of the third component on the formation of RT5 derivative and its influence of the occupied sites on magnetic properties, in this paper, the possible derivative compounds based on the RT5 primitive unit cell of the CaCu5 structure type formed through the ordered or disordered substitution of dumbbell pair 2T atoms for the R atoms at some sites, and the structural relationship between the derivatives and the prototype are summarized.


Recently, CP violation has been observed in the B0 system. The parameter measured, sin 2β, is analogous to ϵ for the K0 system since it can be explained entirely by B0-B̄0 mixing. We label as ϵ′B observables that measure directly CP violation in the ΔB = 1 decay amplitude. A large value for one of these observables would be the definitive evidence against the superweak theory. Problems and prospects for detecting ϵ′B are discussed.

This topic might come as a surprise to the Western, particularly the American reader, who may have believed that the term "judicial review" specifically means judicial interpretation by the U.S. Supreme Court. It is virtually never used in reference to the legal system of the People's Republic of China. In this paper I shall try, using the comparative approach, to convince the reader that "judicial review" does exist in China.


Oil content and fatty acid composition of the 50 bunch peanut types have been reported. The oil content showed little variation, (49.1 ± 2.5%) and of the major component acids, oleic acid showed little variation (44.5 ± 5%) whilst the palmitic (P) and linoleic (L) contents were reciprocally related (P + L ≏ 48%).


In this work, we demonstrate FDSOI ferroelectric FETs (FeFETs) incorporating 4.5 nm hafnium zirconium oxide, which show a ~0.5V memory window at +/-3.3V and a program/erase speed of 1 $\mu \mathrm{s}$. In typical FeFETs where $\geq 9$ nm thick ferroelectric (FE) gate oxides have been used, bulk charge trapping has been identified as the main mechanism for endurance degradation and shrinkage of the memory window (MW). By contrast, we find that the role of bulk trapping in our devices with a much thinner FE layer is minimal. Through a combination of cryogenic temperature-dependent electrical measurements and simulations using the Ginestra ™ modeling platform, we identify and prove that hot electron-induced hole damage during the application of negative gate biases is the primary source of endurance degradation and MW closure in FeFETs with scaled oxide layers.


The Higgs triplet model predicts the existence of the doubly and singly charged Higgs bosons (H±± and H±), whose decay modes are relevant to the vacuum expectation value of the triplet vΔ and the mass spectrum of these scalars. In this paper, we study the pair production of H++H− via the processes in e+e− collisions: e+e−→ H++H−W− and e+e−→ V V∗→ e−ν eH++H−. The numerical results show that the production rates can reach the level of several fb with a center of energy at the TeV scale. The characteristic signals and relevant SM backgrounds are also discussed in both the degenerate and nondegenerate cases. In most of the parameter spaces, their possible signals might be detected via these processes in the future high-energy linear collider experiments with s = 3.0TeV and £int = 1000fb−1.


A novel CMOS temperature sensor embedded in a passive UHF RFID tag is presented. The sensor consists of a temperature-to-current converter, two current-starved ring oscillators and two digital counters. High power consumption band-gap voltage references and traditional ADCs are not used for low power design. Post-layout simulation show that the power consumption is 0.64µW with a supply voltage of 0.8V at room temperature (27°C), and the conversion rate is up to 1 kHz. The average temperature resolution is 0.2°C/LSB from −40°Cr∼120°C. The sensor is implemented in CMOS 0.18µm and the core occupies an area of 0.09 mm2.


Development of Content-Based Image Retrieval systems supports retrieval of similar images based on selected features. Selection of appropriate features for this process is a difficult task. In this regard, deep learning concept helps in choosing appropriate features for retrieval. In this work, Content-Based Image Retrieval system is proposed using Convolution Neural Network known as Residual Neural Network model. The dataset used to build retrieval system is collection of web images 50,000 of 250 categories. The model is trained on 40% of image data and tested on 60% of data. When user submits a query image from the client-side, similar features are extracted by the model on server-side. Later, the features of query image are compared with trained images data and similarity is measured using the metric of Euclidean distance. The retrieved resultant images are displayed on Graphical User Interface. The results are comparatively higher with the existing systems. The proposed work is also compared with Google's Image retrieval system for random query images and our proposed work has shown a better performance by 14.27%.


Spectroscopy was applied to study the mechanism of the new anti-fungal agent TTS-12 against Candida albicans,but results from the infrared spectra analysis did not change significantly.The results of Raman spectroscopy analysis indicated that TTS-12 primarily affected lipid and carbohydrate of C.albicans,which was similar to amphotericin B.The results suggested that TTS-12 might play a role in anti-fungal by affecting the synthesis of membrane lipids of C.albicans.

Arturo Escobar's essay, 'Latin America at a crossroads: alternative modernizations, post-liberalism, or post-development', published in January 2010 in this journal (vol 24, no. 1), offered an important 'conjuncturalist' reading of some political developments in Latin America. It has elicited many comments, raised many important issues within cultural studies, and opened a number of debates between various analytical paradigms. So we invited a number of scholars of Latin American culture and politics to respond to Escobar's essay, and we present them to you here.


Introduction: Incidence of diabetes mellitus has increased over the past few years, mainly due to our eating habits and physical inactivity. This also includes the use of artificial sweetening agents which have broadly replaced other forms of sugars and have shown a paradoxical, negative effect on blood glucose. Ingestion of these artificial sweeteners (AS) results in the release of insulin from pancreas which is mistaken for glucose (due to their sweet taste). This increases the levels of insulin in blood eventually leading to decreased receptor activity due to insulin resistance. Methodology: It is a crosssectional study that was conducted on patients diagnosed with type-2 diabetes mellitus of a tertiary care hospital in Central India. All the diabetics that presented in the OPD were divided into 2 groups based on whether they use AS (group A) or not (group B). Insulin resistance was calculated for each group using HOMA-IR and graphs were plotted. Results: The HOMAIR values for Group A and B ranged from 0.9–24.33 and 0.12–10.83 with mean values 7.39 and 2.6, respectively, showing that the ones who used AS had a higher insulin resistance. The study also showed that the duration of use of artificial sweeteners had a direct impact on insulin resistance.

ABSTRACT This paper identifies critical success factors of Business-managed IT based on case study results. Four groups of critical success factors emerge: (1) general approach to Business-managed IT/Business-managed IT strategy, (2) Business-managed IT project prerequisites/Business-managed IT team, (3) Business-managed IT project execution and outcome, and (4) information technology management for Business-managed IT. The results suggest that bilateral responsibility between the business unit and the IT organization is the most favorable governance option for Business-managed IT.


Today, the education system worldwide is moving their classrooms from teacher-centric environmentto 21st century learning spaces where students are empowered, the classroom is flexible, and the focus is on creation, collaboration, and higher order thinking skills. Making education digital in schools has taken a boom in the field of formal education in India too. In Indian schools digital learning was launched in Dec. 2004 through the scheme ICT@ schools. One of the components of this scheme is capacity enhancement of all teachers in digital learning. Competency is not achieved by just reading material and viewing pages on a computer display but by providing many opportunities for human interaction through teacher-taught discussion, peer-to-peer exercises, discussion groups, and similar activities. This is now the most significant problem to analyse the right blend of traditional and digital learning in teacher education and needs attention of educationists, as it is the need of the hour. For the proposed study a secondary data based analytical research methodology is applied. The study concludes that Teachers remain crucial to learning. When students are actively engaged with digital tools and their teachers, it is most effective. So the teacher must be trained with both traditional theoretical way as well as digital practices. The need is to have a rightblend of traditional and digital learning in our teachers training too. Domination of theoretical training with a slowdown on digital learning would be a terrible idea in this digital era which is facing knowledge explosion worldwide. MHRD,NCTE and appropriate authorities should pay prime attention towards teachers training institutes and provide them all essential support to be competitive globally.


The first formulation of a complete physics, from a logical point of view, was made by Aristotle in the 4th century BC. Aristotelian physics dominated Western thought for almost two thousand years. I will try to show in this text that the Aristotelian theses contain a first prototype of gravitational theory, entirely refuted from current knowledge, but nevertheless important for the context in which it arises and for its diverse implications.

Distributed, networked multimedia information systems are expected to play a major role in the information age of today. Presentation of multimedia information requires temporal synchronization within and among different objects. Network heterogeneity, resource constraints, and random traffic characteristics necessitate intelligent mechanisms for synchronized presentation of multimedia data in distributed multimedia systems. The computational complexity of any such synchronization method has to be small for real-time presentation. The authors use intelligent scheduling procedures to guarantee intra-stream and inter-stream synchronization under network resource constraints. They use the notion of quality of presentation for multimedia data to evaluate the effectiveness of these scheduling algorithms for different resource instances. They present two low complexity (O(n log n), where n is the total number of multimedia presentation units to be scheduled) heuristic scheduling algorithms for real-time applications. They have implemented these algorithms on an asynchronous transfer mode (ATM) network testbed and discuss their performance with respect to two different quality parameters.


SOCIAL SUPPORT AS A BUFFER OF ACCULTURATIVE STRESS: A STUDY OF MARITAL DISTRESS AMONG UNDOCUMENTED, MEXICAN IMMIGRANT MEN by Douglas Costa de Andrade Ribeiro Immigration trends in the United States have changed drastically in the last 20 years. Starting in the 1990's the majority of immigrants have originated from Latin American, with most emigrating from Mexico. Men, some of whom are undocumented, have driven this new wave of immigrants. These new Mexican immigrants have bypassed traditional receiving sites across the U.S. Mexican border and settled in non-traditional sites in the southern U.S. (Kiang, Grzywacz, Marin, Arcury, and Quandt, 2010). They face increased difficulties adjusting to life in the U.S. due to separation from family and spouses, lack of established social support networks in the U.S., and marginalization. Difficulties adapting to a new culture combined with lack of social support have been associated with significant mental health problems in this population (Hiott, Grzywacz, Arcury, & Quandt, 2006). This study explored the relationship between acculturative stress and marital satisfaction, as well as the protective (buffering) role of social support in a sample of 125 undocumented, married, Mexican American men. The following instruments were used in this study: (a) The Social, Attitudinal, Familial, and Environmental Scale (Mena, Padilla, & Maldonado, 1987), (b) the Social Support Questionnaire (Acuna & Bruner, 1999; Sarason, Levine, Bashan, & Sarason, 1983), and (c) the Global Distress Scale of the Marital Satisfaction Inventory-Revised (Negy & Snyder, 1997). Results indicated that high levels of acculturative stress and low levels of social support were significantly associated with higher levels of marital distress.


Mobile banking services have become one of the most important applications on the Internet, being provided by most of the banks all over the world. The end-user can manage the accounts or make some payments without being forced to go to the physical bank office. That's why security concerns regarding authentication have to be taken into the account and the bank should provide various and combined methods for login and payment, in order to increase the confidence in their services for mobile banking. This research paper will introduce some concepts about these two fields: Mobile banking and fingerprint authentication process. During our researches, we developed a Java based Mobile application to simulate access to Mobile Banking for login and payment options. We also perform sample test for this application and as a result, we found it is very secure and 100% successful and user-friendly.


Abstract In this work, we investigate how to decompose a pair $\left( A,\,B \right)$ of loxodromic isometries of the complex hyperbolic plane $\mathbf{H}_{\mathbb{C}}^{2}$ under the form $A\,=\,{{I}_{1}}{{I}_{2}}$ and $B\,=\,{{I}_{3}}{{I}_{2}}$ , where the ${{I}_{k}}$ 's are involutions. The main result is a decomposability criterion, which is expressed in terms of traces of elements of the group $\left\langle A,\,B \right\rangle $ .


develop a fatal Plasmodium kntnolesi infection on inoculation with that plasmodium. By protection tests which showed prolongation of the usually fatal infections or transferenceinto a chronic form without the aid of chemotherapy, Coggeshall and Kumm showed that protective antibodies could be demonstratedregularly in the serum of rhesus monkeys with chronic Plasmodium kno..wlesi· infection. This has been confirmed by other observers. Cog-geshallhas utilized the discovery of Knowles and Das Gupta who produced active malarial infections following inoculations with Plasmodiu In knoiclesi. He inoculated patientssuffering from generalparalysiswith Plasmodium knouilcsi for its therapeuticeffl'ct and he took samplesof serum from these patients at various intervals during their malarial infection and used them in protection experiments with the rhesus monkey. The results, Coggeshall states, show that man, like the laboratory animal, acquiresprotectivesubstancesin his serum during the courseof a knowlesi malarial infection. "That these substancesare acquired as a result of the infection is shown by the fact that they are not present until the chronic stage of the infection has been reached." An interesting observation is recorded which Coggeshall thinks will probably explain failures in previous attempts to demonstratepassive immunity. An effort was made to determine quantitatively the relationship between the amount of immune serum and number of viable parasites in the inoculum. It was found by titration that a definite relationship existed and it was possible to obscure completely the protective effect of a potent immune serum if the number of parasiteswas not kept to a minimum. Becauseprotective antibodies are hard to detect, it does not meanthat they are presentin extremely low dilutions. Coggeshall presumes that the malarial parasite has a Protective covering in the red cell membranewhich prevents an optimal union between the organism and the antibody. According to this idea antibodies might be present in appreciableconcentrationsand yet be unable to exert their maximal I'ffect on the parasite. Coggeshall's conclusion on this aspect of the subject is that the accumulateddata furnish defin ite proof of the existence of the humoral factor in malarial immunity. "Its importance in the defensemechanismhas yet to be evaluated, but the fact that man 01' animal only retainsan immunity to the strainswith which they have had actual experience must mean that some factor or factors in addition to a highly efficient cellular defense mechanismis responsible for the marked degree of specificity encountered with malarial infections." Cog-geshall proceedsfrom the conclusion just stated to show that the concentrationof protective antibodies in a chronic malarial infection is constantly shifting as it respondsto the rate of multiplication of the parasite. He shows that in Plasmodium ktunolesi infections in the rhesus monkey it is possible to produce a hyperimmune serum of high potency with repeatedinoculations of massive numbers of living parasites. This is an indication that the host is responding,although there is no change in the numbers of circulating parasites. In nature, Coggeshallpoints out, the sameresult is probably obtained through the constantexposureof individuals to the bites of infected mosquitoeswhich may serve as a stimulus to maintain a high level of immunity. Referencehas already been made to people living in the tropics, obviously not ill, but harbouring in the blood stream considerable numbers of parasites. Although the exact role of theprotectiveantibody has not been demonstrated,Coggeshall refers to experimental evidence which suggeststhat theantibody acts as an opsonin and alters or sensitizesthe' parasite so that it becomes more susceptible to phagocytosis. According to this view "the effective functioning of the defensiveefforts of the host does not dependsolely upon a cellular or humoral basis,but upon the cooperative' efforts of both". Two aspectsremain to be mentioned. The first has to' do with the duration of immunity. In this regard it must be rememberedthat there is no way of showing whether" the host is resistant becauseof a residual immunity following the complete disappearanceof an infection or because of the presence of an undetectable infection. Coggeshall gives three main reasons why it is almost impossible to know the statusor duration of immunity.

Objective:To investigate the influence of complete denture wears' experience on chewing efficiency.Methods:A detailed study was made,through spectrophotometry,in two groups of patients (both were edentulous;the testing group,with previous complete denture wearing experience,and the control group,without).The chewing efficiency in different periods of time,2 weeks,1,3,4,5,6 months was compared.Results:The chewing efficiency of the two groups was different at different periods of time.The test group's efficiency was stronger in the early period,then decreased a month later.Efficiency in control group was improved three months later.Thereafter,the difference between the two groups began to diminish,and finally disappeared six months later.Conclusion:1.Testing the chewing efficiency with spectrophotometry is considered to be reliable and stable method.2.The chewing efficiency tends to rise within the first six months.3.The experience of complete denture has a helpful effect on the restoration of chewing efficiency.


Residing in Gurgaon, a city close to Capital, being a hub of MNCs, a symbol of globalized culture, and known for its luxurious, exotic life style has its own pluses or plushes, I must say. Surrounded by latest technical products like swanky iphones, ipads, tabs, exotic cars, lavish homes, sky rocketing, fancy and designer buildings, trendy malls, stylish apartments, elegant clubs, the city is symbol of modernization thus indicating a shift in the manner in which people live and work.However, seemingly, the economic growth is not resulting in equitable distribution of wealth, resources or improvement in quality of life for all its inhabitants. Moreover, globalization is making a drastic impact on social relations as well as love, care, and emotions within a family, and in general, creating a situation which is adverse for women and children. It may be said that the city is becoming a symbol of a power, status, sumptuousness, opulence and affluence where the desire for money, wealth, status and professional achievement is surpassing the desire for love, care, affection and above all humaneness.


The paper presents a method for assessing the accuracy of in-line inspection (ILI) results. The main objective of the method is to determine whether the measurements obtained by ILI are adequate and acceptable. If too few measured dimensions of defect parameters (for example, their depths) fall within the range of values obtained using verification results, this indicates that the ILI tool incorrectly estimated the actual data. Thus, the lower (upper) limit is estimated for the number of satisfactory (unsatisfactory) ILI tool measurements.


Girl Education is a global issue. Many reports and papers, including UNESCO reports on gender monitoring and education highlight the intensity of the challenge across the world. It is underpinned by myriad factors ranging from a genuine desire on the part of the family to protect and safeguard the girls in specific contexts to cultural determinants, social manipulations, gender discrimination, economic priorities, religious interpretations, political exploitations, vested interests, and simple pragmatics, among many others. However, the nature of these factors and their combinations vary in diverse societies influenced by dominant cultural and belief systems, as well as by the economic parameters. Girl education in rural Pakistan is a serious cause of concern. In some regions, the literacy gap between men and women is as large as 45 percentage points (Simons, 2007). It is alarming that in Pakistan, 47 percent of all girls never enrol in a school (McCutcheon, 2007). Economic imperatives emerge as a significant factor but the feudal patriarchal structure of the society (Mernissi, 1991; Shah and Conchar, 2008; Weiss, 1994), religious discourses (Al-Hibri, 1982; Talbani, 1996), gendered roles and stereotyping (Griffin, 2006; Shah, 2008), entrenched traditions and practices underpinned by public/private divide (Afshar, 1991; Seller, 1996; Shah, & Conchar, 2007) and a lack of relevant effective responsive policies exacerbate the situation. This paper attempts to debate the issue, inviting to respond to legitimate concerns, to involve all stakeholders, to solicit social mobilisation, to remove practical barriers, to facilitate acceptable structures, and to ensure effective outcomes. The underlying argument is that ensuring education for girls is crucial, not only for resolving gender inequities, but it is also critical for combating with personal and national poverty.


When Total Fertility Rate is getting lower, some even reach below the replacement level, the opportunity for women to enter the labor market is getting bigger. They are well educated so it is natural that labor participation rate is increasing too. But on the contrary, the employment opportunities is limited and caused a part of them to become an open unemployment and underemployment. Por those who already work, most of them work in non- agricultural sectors as half skilled manpower in other sectors. por the last 25 years, there has been a change in labor market for women, but there is still a wage gap between men and women for the same job.


. In order to promote the high-quality and sustainable development of the alternative fuel vehicle industry, the Chinese government has given strong tax policy support. In China, the corporate income tax rate is uniformly 25 %, and the government gives tax incentives to high-tech enterprises that meet the relevant appraisal standards: the tax rate is reduced by 15 %. The purpose of this work is to analyze the impact of China's tax policy on the production of vehicles using alternative fuels and to assess the significance of tax incentives for the formation of significant incentives for the development of this production. The hypothesis of the study is to confirm the need to provide incentives for high-tech production of vehicles using alternative fuel to maintain a positive financial result of such production. This paper uses the OLS analysis model. Deriving data from the annual financial reports of BYD, Geely, SAIC Motor and Great Wall Motor from 2011 to 2020, analysis is carried out of the impact of income tax rate and debt ratio on net profit margin. Research has confirmed that income tax is positively correlated with net profit margin, and the debt ratio is negatively correlated with the corporate net profit margin. The higher the debt ratio, the less conducive to the improvement of the company's net profit margin. Corporate net profit margins are more sensitive to changes in income tax. This also provides an effective way to improve the tax policy to promote the development of new energy vehicles. Tax policy is the most effective tool for the government to carry out macro-control, helping to avoid the harm caused by "market failure" and guiding the development direction of the production of vehicles using alternative fuels.


We analyze the signal-signal beating interference (SSBI) when optical orthogonal frequency division multiplexing (OOFDM) signal is directly detected by photodiode at the receiver. We propose a novel training sequence configuration to reduce SSBI. The experimental results show that the receiver sensitivity of the OFDM signal with the new training sequence at the BER of 1 10 3 is 2.4 dB better than that with standard training sequence after transmission over 100 km standard single mode fiber (SSMF) at a bit rate of 2.5 Gbit=s.


Purchase-decision involvement is distinguished from product-class involvement. Literature on consumer involvement is shown to be lacking a measure of purchase involvement. Therefore, a scale of purchase-decision involvement is developed. Two empirical studies are described and are shown to furnish tests of convergent and discriminant validities. The individual items of the proposed scale are explicitly embedded in the purchase-decision context, and the scale is simple and parsimonious, making it especially useful to practitioners.


The idea of this study was to be vigilant with rust virulence pattern changes in the region and to organise wheat breeding and variety release programmes in the light of findings of rust virulence patterns. The survey was carried out during March–April (2010 and 2011) on the rust trap nurseries planted at different Agra-ecological condition in Pakistan. The rust trap nursery consisted of 40 Lr differentials and 24 Yr differentials and data were recorded following modified Cobb's scale. The studies revealed that there were no virulence for Lr9, Lr19, Lr23+, Lr25, Lr28, Lr27+31 Lr32, Lr34, Lr36 and Lr37 and Yr3, Yr5, YR8, Yr10, Yr15, Yr18, and Yrsp observed during this period. Among the varieties Iqbal-2000, Uqab-2000, Lasani-2008, Faisalabad-2008, AARI-2011, Millat-2011 and Pb-2011 exhibited resistance path for LR and YR. Moderate YR was observed on Shafaq-2006 & Chenab-2000 ranging from 20–30 M RMS. In these studies the susceptible check variety Morocco was almost 80–100S for LR and YR.


A new indirect scheme for encoding neural network connection weights as sets of wavelet-domain coefficients is proposed in this paper. It exploits spatial regularities in the weight-space to reduce the gene-space dimension by considering the low-frequency wavelet coefficients only. The wavelet-based encoding builds on top of a frequency-domain encoding, but unlike when using a Fourier-type transform, it offers gene locality while preserving continuity of the genotype-phenotype mapping. We argue that this added property allows for more efficient evolutionary search and demonstrate this on the octopus-arm control task, where superior solutions were found in fewer generations. The scalability of the wavelet-based encoding is shown by evolving networks with many parameters to control game-playing agents in the Arcade Learning Environment.


Torque control method is usually used in screw-in primer assembly,which may result in excess tighten because of the long response of its torque control ring,thus lead to error wrench scratch and screw device damage. Aiming at these problems,we mended hard platform of the torque control ring and adopted a screw method with real-time clipping control of higher response frequency to command tappet head torque output during tighten and assembly. Result shows the method can greatly advance torque control precision in the process of last tighten,while avoid excess torque adjustment and achieve excess tighten prevention in primer screw up,linkage and assembly.


In this paper, commercially cold-rolled and artificial aged EN AW 7075 T6 alloy has been used. To ensure increased corrosion resistance, surface hardness, scratching resistance, and aesthetic features, this aluminium alloy was subsequently hard anodised and hot-water sealed (AC-A). The hard anodizing and sealing process increased surface hardness up to 304±13 HV 1 from an initial surface hardness of 194±3 HV 1. Also, the microhardness of the anodised layer and bulk material has been documented. Scanning electron microscopy (SEM) was used for microstructure and trapped precipitates investigation in the 42.9±1.4 thick formed anodised layer investigation. The T6 treated (AC) and hard anodised together with sealed (AC-A) EN AW 7075 alloy corrosion properties were evaluated using the anodic potentiodynamic polarisation tests (PPT) in a neutral 2.5% NaCl deaerated solution. The corrosion rate CR (mm/y) decreased approx. 39-times for the hard anodised and sealed EN AW 7075 alloy (AC-A), associated with the shift of the Ecorr (mV) to more positive values, degreased Icorr (µA) and increased Rp (Ohm) values compared to the artificial aged (AC) alloy. Additionally, the pitting was evaluated using laser confocal microscopy, and the pitting coefficient was also calculated.


A proper understanding of boundary-value problems is essential in the attempt of developing a quantum theory of gravity and of the birth of the universe. The present paper reviews these topics in light of recent developments in spectral geometry, i.e. heat-kernel asymptotics for the Laplacian in the presence of Dirichlet, or Robin, or mixed boundary conditions; completely gauge-invariant boundary conditions in Euclidean quantum gravity; local vs. non-local boundary-value problems in one-loop Euclidean quantum theory via path integrals.


Albert Collis is an 80-year-old man who was admitted to the intensive care unit with an episode of acute pancreatitis, 6 weeks before a critical incident in his tracheostomy care. His pancreatitis was managed medically, with part of this treatment involving mechanical ventilation. Although the pancreatitis responded well to treatment, Albert developed a chest infection and proved difficult to wean from the ventilator. A tracheostomy was therefore performed 2 weeks after admission, both for Albert's comfort and to facilitate the weaning process. Albert's muscles had wasted considerably during his admission and his respiratory muscles were very weak. In the 4 weeks following his tracheostomy he had progressed slowly from pressure control mode to synchronised intermittent mandatory ventilation and pressure support, to pressure support only. He then went on to a continuous positive airway pressure circuit, and for the 2 days before the incident had been on a T-piece with a thermovent humidifier with 28% oxyge...


Let (X,Y ) be a random variable consisting of an observed feature vecto r X ∈ X and an unobserved class label Y ∈ {1, 2, . . . , L} with unknown joint distribution. In addition, let D be a training data set consisting of n completely observed independent copies of (X,Y ). Usual classification procedures provide point predictors ( classifiers)Ŷ (X,D) of Y or estimate the conditional distribution of Y given X. In order to quantify the certainty of classifying X we propose to construct for each θ = 1, 2, . . . , L a p-valueπθ(X,D) for the null hypothesis that Y = θ, treatingY temporarily as a fixed parameter. In other words, the point pr edictorŶ (X,D) is replaced with a prediction region for Y with a certain confidence. We argue that (i) this approach is advantegeous over traditional approaches and (ii) any re asonable classifier can be modified to yield nonparametric p-values. We discuss issues such as opt imality, single use and multiple use validity, as well as computational and graphical aspects.


We have shown that successive Lorentz transformations (LT) lead to ambiguous values for time and space, because of Wigner rotation and associated non associativity of LT. We have proposed a reciprocal symmetric transformation (RST) which gives unique values for time and space. RST also gives a rotation comparable to Wigner rotation. RST is complex. We have shown that the imaginary part corresponds to spin of Dirac electron.


Aquatic products price index is an important index in fisheries economic development.In today's rapid development of economy,predicting aquatic products price index has a crucial role to the fishery economy.Through a variety of time series forecasting methods(moving average method,weighted moving average method,the two moving average method and exponential smoothing method),the price index of shrimp and aquatic products were predicted.And the accuracy of the results was compared.Finally,the most accurate method was determined and it was used as the final prediction of shrimp and crab price index.


A strong presence of the microfinance sector has been felt in many developing economies of the world. Thus, the objective of this paper is to analyse and -compare the performance of the industry in six South Asian countries namely Bangladesh, India, Pakistan, Afghanistan, Nepal and Sri Lanka which are geographically near to each other. To evaluate the performance of these countries, Fixed Effects panel data estimations in E-views has been used. A significant difference in performance has been witnessed on all 14 parameters of performance. Extensive manual calculations have been done to compare and rank the countries based on the selected parameters. Bangladesh bags the first position closely followed by India while Afghanistan ranks last. A theoretical framework has been developed to understand and analye the reasons for the difference in the performance of the six countries.


Depression is one of the most common mental health disorders globally, presenting an increasing burden everywhere — as are hypertension-related diseases. Depression nearly doubles the risk for developing coronary heart disease, and in those already suffering from heart disease, depression nearly doubles the risk of mortality. This elevated cardiac risk associated with depression is independent of classical risk factors, and similar in degree to smoking and hypercholesterolaemia.


This work considers the problem of tracking a mobile object with an unknown shape based on noisy point cloud measurements from the object contour. For this purpose, an Expectation Maximization (EM) method is developed that is capable of simultaneously estimating the location and shape parameters of an object based on a temporal sequence (i.e., batch) of point clouds. The benefits of the EM approach are evaluated with respect to a standard Kalman filter that performs a greedy association of measurement points to contour points. Especially for scenarios with high noise and sparse point clouds, the batch processing scheme of the EM approach is beneficial.


Predicting flash floods at short time scales as well as their impacts is of vital interest to forecasters, emergency managers and community members alike. Particularly, characteristics such as location, timing, and duration are crucial for decision-making processes for the protection of lives, property and infrastructure. Even though these characteristics are primarily driven by the causative rainfall and basin geomorphology,  untangling the complex interactions between precipitation and hydrological processes becomes challenging due to the lack of observational datasets which capture diverse conditions.

This work follows upon previous efforts on incorporating spatial rainfall moments as viable predictors for flash flood event characteristics such as lag time and the exceedance of flood stage thresholds at gauged locations over the Conterminous United States (CONUS). These variables were modeled by applying various supervised machine learning techniques over a database of flood events. The data included morphological, climatological, streamflow and precipitation data from over 21,000 flood-producing rainfall events – that occurred over 900+ different basins throughout the CONUS between 2002-2011. This dataset included basin parameters and indices derived from radar-based precipitation, which represented sub-basin scale rainfall spatial variability for each storm event. Both classification and regression models were constructed, and variable importance analysis was performed in order to determine the relevant factors reflecting hydrometeorological processes. In this iteration, a closer look at model performance consistency and variable selection aims to further explore rainfall moments’ explanatory power of flood characteristics.


The present investigation was framed in a scientific and experimental study on the topic:
THE USE OF TEACHING MATERIAL TO IMPROVE THE LINGUISTIC
DEVELOPMENT OF CHILDREN FROM 4 TO 5 YEARS OF THE "HUGO
GUILLERMO GONZALEZ" INITIAL EDUCATION CENTER PARALLEL "A" IN
THE CITY OF LOJA, ACADEMIC YEAR-PERIOD 2017-2018, the general objective
of this research study was aimed at determining the incidence of the use of didactic
material to improve the linguistic development of children from 4 to 5 years of the Initial
Education Center "Hugo Guillermo Gonzalez" Parallel " A "from the city of Loja,
academic year-period 2017-2018. The methods used were as follows: the scientist,
analytical - synthetic, inductive-deductive and statistical. The techniques used for both
children and teachers were the observation card, and the instrument was the Articulation
Test for Repetition. Such a test was administered to the 21 children, obtaining the
following results: 100 percent of the population omit and replace some phonemes, and
about 10 percent of the children distort them. And finally, regarding the phonological
aspect, 100 percent of the research sample had not consolidated it. Hence, a proposal
"Developing my language" was elaborated and developed, and it was validated through a
post-test. The test results show that 52 percent of the 21 children decreased the omission
of the phonemes, 38 percent did not substitute them and 95 percent did not distort the
phonemes at the time of speaking. In the phonological aspect, 33 percent of children
achieved consolidated learning, 38 percent of them were in process, and 29 percent of
them presented initial learning. It was concluded that the established proposal is valid
since it evidenced improvement in the language of children in terms of the production of
phonemes, such as omission, substitution and distortion and consequently, it is
recommended to continually stimulate the language of children in initial education,
through activities that include didactic material


This study was done to determine the effect of complete replacement of maize with maize/sorghum-based brewers' dried grains (MSBDG), jackbean (JB) and cassava root meal (CRM) on performance of finisher broilers and the feed cost implication of using these test materials as the major energy sources. Four experimental diets T1, T2, T3 and T4 were formulated to contain maize, MSBDG, JB and CRM in the following proportions 60, 0, 0, 0%; 0, 20, 15, 25%; 0, 20, 20, 20%, and 0, 20, 25, 15% respectively. Other ingredients were the same for the four diets. One hundred and sixty eight (168) 4-week-old Hubbard broilers were divided into 4 treatment groups of 42 birds each; and each group subdivided into 3 replicates of 14 birds per replicate. Each treatment group was randomly assigned to an experimental diet in a completely randomized design (CRD) experiment. The feed intake of T1, T2 and T4 birds were similar (P>0.05) but lower (P 0.05) difference in daily weight gain between T1 (1.70g) and T2 (1.55g) birds. The feed conversion ratio of T1 birds was better (P<0.05) than T2, T3 and T4 birds. The feed cost of N195.58 for T4 required to produce 1kg meat was lower than the cost of N214.50 required for meat production in T1. Generally, the MSBDG/JB/CRM feeds produced 1kg meat at costs 6.17%, 3.71% and 8.82% for T2, T3 and T4 lower than the T1 diet.


Since its introduction ten years ago, Anolis sagrei has spread over much of Grand Cayman and is now more common in some habitats than the native anole, A. conspersus. Interspecific differences in body size, perch height, and microclimatic preference may have facilitated the colonization. Nonetheless, competition may be occurring between the species; comparisons with studies of habitat use prior to the arrival of A. sagrei indicate that in open habitats, where A. sagrei is now abundant, A. conspersus perches higher, but in closed habitats, where A. sagrei is absent, no change in perch height is evident. Review of data concerning 23 Anolis introductions indicates that the presence or absence of an ecologically similar native species may be an important determinant of colonization success or failure. Key words" Invasion Competition Community constructionIslands Lizards Although community ecologists have intensely debated which factors are responsible for maintaining community structure, only recently is equivalent attention being devoted to the factors affecting the construction of communities (Drake 1990, 1991; Brooks and McLennan 1991). Several authors have suggested that in communities which arise by sequential immigration of species (such as oceanic islands), community structure is shaped by both the relatively rapid processes acting in ecological time and the slower processes acting over evolutionary time (Roughgarden et al. 1983; Rummel and Roughgarden 1983; Case 1983; Case and Sidell 1983; Grant 1986). Moreover, kinds of communities may differ in the relative importance of ecological vs. evolutionary processes, which may lead to systematic differences in community structure (Rummel and Roughgarden 1983, 1985; Schoener 1986; Taper and Case 1992a, b). For example, in "invasion-structured communities" (using the terminology of Rummel and Roughgarden [1983, 1985]), an invading species must Correspondence to: J.B. Losos be pre-adapted to coexist with members of the community by sufficient differences in resource utilization or competition will result in the extinction of either the invader or one or more residents (here we focus on competition, but the concept is easily extended to other types of interactions, such as predation). By contrast, in "coevolution-structured communities", competition leads to evolutionary changes that may result in coexistence. Behavioral shifts have also been observed in Anolis (Jenssen 1973); although not explicit in the simplest models, they could be part of either scenario. Lizards of the genus Anolis are ideal for analyzing community construction and faunal accumulation. Many studies (references in Losos 1990a) have documented the interactions within simple and complex communities on Caribbean islands. The extent to which these communities result from coevolutionary processes, and whether any existing simple community represents a first stage in the faunal buildups culminating in the species-rich anole communities of the Greater Antilles, is unclear (see Williams 1972; Roughgarden 1989, 1992; Losos 1992a, b). The study of introductions of non-native species can provide valuable data relevant to understanding the dynamics of community assembly (e.g., Moulton and Pimm 1983, 1986). A great number of human-assisted anole introductions have been documented in the Caribbean region. Examination of the outcome of these events may provide an analogy useful in understanding the evolution of anole faunas in the Caribbean. In this paper, we discuss the recent introduction of Anolis sagrei to Grand Cayman (l14km2), an island previously occupied solely by A. conspersus. Anolis sagrei was first detected on Grand Cayman in the western part of the island (Minton and Minton 1984); it now occurs throughout much of the island (G.C. Mayer, pers. comm.; Losos and Marks, unpubl, obs.). Below, we first discuss differences in habitat use between A. sagrei and A. conspersus and present evidence of habitat shifts by the latter in the presence of the former. We then review the history of Anolis introductions to assess the relative importance of ecological versus coevolutionary processes in the construction of anole communities.


Botnets, which consist of thousands of compromised machines, can cause significant threats to other systems by launching Distributed Denial of Service (SSoS) attacks, keylogging, and backdoors. In response to these threats, new effective techniques are needed to detect the presence of botnets. In this paper, we have used an interception technique to monitor Windows Application Programming Interface (API) functions calls made by communication applications and store these calls with their arguments in log files. Our algorithm detects botnets based on monitoring abnormal activity by correlating the changes in log file sizes from different hosts.


The growing penetration of distributed generation (DG) power plants into distribution networks causes several issues concerning, e.g., stability, protection equipment, and voltage variations. One of the main topics is steady state voltage rise because of DG's active power injection. This paper presents a detail analysis of how does voltage rise on distribution network due to the penetration of DG and reviewed some related recent papers that analyzes voltage control problem. Also in this paper, a novel method is proposed to control voltage in distribution network that includes both local and coordinated reactive power control. To verify validity of suggested strategy, a real medium voltage network is considered and task of controlling voltage is provided with mathematical formula in different situations.


Liu Xie's "vicissitudes" and Ye Xie's "ZhengBian"play a prominent role in traditional Chinese poetics respectively.Liu Xie prefers to stick to coquettish classical style of writing through which current malpractices might hopefully be rectified.On the contrary,Ye Xie's "ZhengBian" aims at changing the rigidified wordy style.Ye Xie's "ZhengBian" is better for poetic creation for it allows poets to develop their imagination,which cannot be done by simply following Liu Xie's "vicissitudes".Ye Xie's "ZhengBian" is exactly the renaissance of Confucius's poetics.


I can still remember the first patient with long-QT syndrome (LQTS) that I treated. It was 1992 and I was an intern at the Hospital of the University of Pennsylvania. She appeared on my outpatient clinic schedule, "Mrs. XXX, follow-up, LQTS." When I saw that, my reaction was mixed: fear (Why is she seeing me? I am an intern! Shouldn't she be seeing an expert?!!) and excitement (Oh boy! Someone with a congenital arrhythmia. What a great case! I have only read about these so far!!). I was certain that my hoped-for career as an electrophysiologist was about to blossom. The patient had other ideas. She was not at all impressed with my intern enthusiasm. She had been doing just fine for decades without my intervention. She planned to continue to do just fine. Could I please just renew her metoprolol script for another year, and she would see me then. Thank you very much. I did what I was told: renewed her β-blocker and saw her back in 1 year, thank you very much. She did fine. It amazes me how much our knowledge about this syndrome has grown in the short time since that encounter, and yet how many unanswered questions we still have. The first causative genes were identified in 1995.1-3 Even today, associations with different gene mutations continue to roll in on a regular basis. These ground-breaking discoveries have revolutionized our understanding of LQTS, as well as many other arrhythmic diseases. What we need now is more practical information about management of these patients. It has been 53 years since the original report by Jervell and Lange-Nielsen,4 and 15 years since the initial reports identifying causative genes, but we cannot confidently answer questions regarding the best management for these patients. In the current issue of the Journal, Goldenberg et al. contribute valuable information to this cause.5 In a nutshell, they find that very low-risk patients have such a small frequency of events that β-blockers do not provide a significant benefit, very high-risk patients continue to have recurrent symptoms in spite of substantial benefit from β-blocker therapy, syncopal episodes nearly always precede cardiac arrest for patients taking βblocking drugs, and cardiac events during β-blocking therapy


Using a circular beam separator to deflect the primary beam of an SEM through 90deg, an aberration limited final probe size of 7-8 nm has been achieved in experiments. This limit was shown to be due to magnetic leakage fields from the post-deflector lens and not due to aberrations of the beam separator. In fact, it is concluded that the beam separator aberrations are within 2 nm over a 1 mum by 1 mum field-of-view, in agreement with previous simulation predictions. The results presented in this paper therefore confirm the feasibility of the spectroscopic SEM concept, from the imaging point of view, the next step is to acquire energy spectra. To further improve on the current setup, it is clear that a post-deflector lens without significant magnetic leakage field must be used. In addition, the lens should not be a transmission type as the SPSSEM relies on scattered electrons travelling back towards the beam separator. Such a lens has been designed and manufactured and is an immersion magnetic lens design which will be useful not only for imaging but also for spectrum experiments in the future


Undergoing development for 20 years,DFN model and DFM model makes considerable progress and has been reliable programme for exploitation of fissure oil-gas reservoir.However,some problems are still present in the actual application due to complexity of the fissure oil-gas reservoir.The present paper deals with the existing problems which are of great importance to the modeling of fissure oil-gas reservoir.


Social work organizations have actively been seeking licensure. This paper explores the impact of a licensure model using survey data of registered social workers gathered in Michigan. The effect of restricted entry to social work through licensure is apparent on characteristics of providers, clients and settings. The sharpest impact of licensure under the National Association of Social Workers (NASW) model is on the types of services provided. Those eligible are generally providing peoplechanging services while those ineligible are generally providing people-processing services to clients. This outcome is contrasted with the broad multifaceted definition social work organizations intellectually support.


Under USDOE sponsorship, a project team consisting of the Institute of Gas Technology (IGT), Peabody Holding Company, Inc., and Bechtel Group is developing a process for the mild gasification of coal in a 100-pound/hour capacity isothermal process research unit (PRU) at IGT in Chicago. The IGT process is capable of converting bituminous coals to value-added co-products that can open new markets for the US coal industry. The conceptual IGT mild gasification process incorporates an integrated fluidized-/entrained-bed reactor supplying heat indirectly by a combination of char and gas recycle. The use of mild operating conditions (1000{degree} to 1300{degree}F), low pressures (<50 psig), and continuous operation in closed reactors, combined with the sale of value-added co-products, offer an environmentally sound and economical approach to advanced coal utilization. The PRU consists of an 8-inch-ID {times} 8-foot-long fluidized-bed reactor closely coupled to a 4-inch-ID {times} 13-foot-long entrained-bed reactor. The PRU test results have demonstrated process performance, including the effect of coal type and temperature on mild gasification co-product yields and their properties. The fates of the heteroatoms have also been analyzed. 9 refs., 16 figs., 41 tabs.


-One of the uses of smart phones (smartphones) is that they are used to help children's learning process with various applications that are easy to install. Learning that is often carried out for early childhood is an introduction to animals and their habitats, this learning can help early childhood to get to know various kinds of animals and their habitats. Understanding of animal names needs to be done especially on Sumba Island which is an area in East Nusa Tenggara, on the island of Sumba itself which is famous for its unique customary and cultural values. The customs and culture that exist in Sumba often use animals as the main part in carrying out traditional activities, so understanding related to animal species needs to be understood from an early age, one of which needs to be learned is to use the local language. This is taught to children in local content lessons. However, there are several problems in the delivery of subject matter to early childhood using conventional methods, one factor is that it is easy to get bored in learning, and it is difficult to understand and remember the learning material provided. Based on these problems, an educational game application was built in 3 languages, namely Sumbanese, English and Indonesian so that it can become a new learning medium, in this study the game was built using the MDLC (Multimedia Life Cycle) Method. through functional testing and experience an increase in understanding of children by 10% through the results of the pre test and post test given.

The Digital Access to a Sky Century@Harvard (DASCH) project is digitizing the ∼500,000 glass plate images obtained (full sky) by the Harvard College Observatory from 1885 to 1992. Astrometry and photometry for each resolved object are derived with photometric rms values of ∼0.15 mag for the initial photometry analysis pipeline. Here we describe new developments for DASCH photometry, applied to the Kepler field, that have yielded further improvements, including better identification of image blends and plate defects by measuring image profiles and astrometric deviations. A local calibration procedure using nearby stars in a similar magnitude range as the program star (similar to what has been done for visual photometry from the plates) yields additional improvement for a net photometric rms of ∼0.1 mag. We also describe statistical measures of light curves that are now used in the DASCH pipeline processing to identify new variables autonomously. The DASCH photometry methods described here are used in the pipeline processing for the data releases of DASCH data, as well as for a forthcoming paper on the long-term variables discovered by DASCH in the Kepler field.


Transportation planning in general and planning for intelligent transportation systems (ITS) in particular are notable both for multiple goals and for multiple constituencies. In response to complex policy environments such as this, multicriteria decision analysis often was utilized to assist in the evaluation of alternative investments or policy directions. This approach is extended here to assess stakeholder valuation of broad goals of an ITS planning process, the Suburban Mobility Authority for Regional Transportation (SMART) operational field test in the metropolitan Detroit area. Two levels of goals were considered: broad system wide goals and specific service characteristics, such as advance reservations, scheduling, and reliability. Using a modified Analytical Hierarchy Process, implicit preference weights for transportation planning goals were derived, and inter- and intra-group comparisons were made. Overall, there was less variation between groups in preferences than might be expected, indicating a fair degree of common ground in desired outcomes of transit planning. The ability to provide for the trips that people request, referring both to the accommodation of trips and the match between requested and scheduled times, were important goals across various stakeholder groups. Similarly, the provision of reliable service was generally valued highly. Information provision appears to be a lower priority. To the extent that automatic scheduling and dispatch assists improved scheduling, trip reservation, and routing, it is likely to meet stakeholders' preferences.


In this paper, based on the concept of adaption, the Cost-Evaluating Symmetrical Reversible Variable Length Codes (C-E SRVLCs), which can be used for Joint Source Channel Coding (JSCC), are constructed through a user-defined cost function. The principle of C-E SRVLCs is explained and analyzed, and simulations are carried out for two common channels(BSC and AWGN). The results show that the codes are superior to the traditional separate codes, and may found applications in some areas.


We investigated three main advantages of the photocantilever, i.e., a microfabricated photocantilever with pn-junction type photodiode on its tip, compared to other NSOM probes. The tip of the photocantilever converts the sample-modulated evanescent light into scattered light that can be collected by the photodiode fabricated at the apex of the cantilever. We demonstrated efficient collection of the scattered light, i.e., the NSOM signal light, availability of simultaneous NSOM/AFM microscopy, and the good responsivity to visible light. The photocantilever-based NSOM signal is one order of magnitude larger than that reported for AFM-cantilever-based NSOM. The minimum detectable NSOM power that we obtained was several tens of pico watts. By locating the optical-lever laser spot for AFM regulation over 100μm from the pn-junction, the photocurrent generated by the laser spot can be reduces for NSOM measurement. This enables simultaneous NSOM/AFM using the photocantilever. The resultant NSOM lateral resolution is better than 20nm (λ/30) and vertical resolution is better than 5nm. The spectral response shows that the photocantilever responds to visible light and the spectral response has a peak at about 500nm. The photocantilever enables simultaneous near-field scanning optical microscopy and atomic force microscopy, which measure both optical and topographical distributions with nanometer-resolution.


Huntington's disease (HD) is an inherited genetic disorder, characterized by cognitive dysfunction and abnormal body movements, and at present there is no effective treatment for HD. Therapeutic options for HD are limited to symptomatic treatment approaches and there is no cure for this devastating disease. Here, we examined whether SUN N8075, (2S)‐1‐(4‐amino‐2,3,5‐trimethylphenoxy)‐3‐{4‐[4‐(4‐fluorobenzyl)phenyl]‐1‐piperazinyl}‐2‐propanol dimethanesulfonate, which exerts neuroprotective effects by antioxidant effects and induction of VGF nerve growth factor inducible (VGF), has beneficial effects in STHdh cells derived from striatum of knock‐in HD mice and R6/2 HD mice. In an in vitro study, SUN N8075 inhibited the cell death caused by mutant huntingtin (mHtt) and upregulated the VGF mRNA level via the phosphorylation of extracellular signal‐regulated kinase 1/2 (ERK1/2). Furthermore, 30 amino acid of VGF C‐terminal peptide, AQEE‐30 inhibited the cell death and the aggregation of mHtt. In an in vivo study, SUN N8075 improved the survival and the clasping response in the R6/2 mice. Furthermore, SUN N8075 increased the number of surviving neurons in the striatum of the R6/2 mice. These findings suggest that SUN N8075 may be an effective candidate for HD treatments.

From this information is derived a rough picture of the number and scope of indexes needed to pro vide complete access to little magazines.


BACKGROUND
This study aims to determine whether periodontal conditions or dental health behaviors are risk factors for preterm birth (PTB), and whether periodontal pathogens are risk indicators for PTB among Korean mothers.

METHODS
This study was designed as a hospital-based case-control study. Examiner masking was ensured for the validity of the examinations. The mothers included those who gave birth between November 2007 and July 2009 at the obstetrics clinic of a general hospital in Seoul, Korea. Information on demographic and health conditions, periodontal conditions, and microbacterial data was collected.

RESULTS
A total of 172 women met the inclusion criteria, 59 mothers who delivered a preterm neonate were assigned to the case group while the other 113 were assigned to the control group. There were no significant differences in demographic information, oral health conditions, and obstetric characteristics. Among health-related behaviors, only scaling within 12 months before pregnancy showed a significant difference (P = 0.031). Even in the adjusted logistic model, only the difference in the experience of scaling before pregnancy was significant between the PTB cases and the controls (P = 0.039). Periodontal disease did not exhibit a significant relationship with PTB even after adjustment for potential confounding factors. Among the microbacterial factors, only Porphyromonas gingivalis showed a slight difference (P = 0.060).

CONCLUSION
There was a significant difference in scaling experience within 12 months before pregnancy and P. gingivalis showed a marginal difference between the PTB and the control groups but clinical periodontal conditions showed no association with PTB.


BACKGROUND Lymphadenopathy is a common clinical condition and biopsies are usually undertaken to determine the cause of nodal enlargement, which may be neoplastic or non-neoplastic. The neoplastic disorders are categorized into haematolymphoid malignancies and metastasis, while the causes of non-neoplastic lymphadenopathy are diverse. This study was undertaken to determine the histopathological spectrum in lymph node biopsies. METHODS This was a descriptive study of 357 cases of histologically diagnosed peripheral lymph node biopsies in the Department of Pathology, Govt. Medical College, Thiruvananthapuram, Kerala, S. India conducted from January 2019 to December 2019. Treated cases of malignancies were excluded. RESULTS The non-neoplastic lesions were more common accounting for 67.2 % (240 cases) which included 40.3 % (144 cases) of non-specific reactive lymphoid hyperplasia, 3.9 % (14 cases) of other specific lymphoid hyperplasia, 16.2 % (58 cases) of tuberculous lymphadenitis, 6.7 % (24 cases) of other granulomatous lesions. Neoplastic lesions accounted for 32.8 % (117 cases) and included 16.2 % (58 cases) of non-Hodgkin's lymphoma, 3.9 % (14 cases) of Hodgkin's lymphoma and 12.6 % (45 cases) of metastatic lesions. CONCLUSIONS Lymph node biopsy plays an important role in establishing the cause of lymphadenopathy. Among the biopsied nodes, reactive follicular hyperplasia was the most common (40.3 %) followed by Non-Hodgkin's lymphoma and tuberculous lymphadenitis (16.2 % each) and metastasis (12.6 %).

This investigation studied the uptake of methylene blue from wastewater by normal and treated bentonites to evaluate the effects of acidification factors on removal efficiency. Hydrochloric, sulphuric and nitric acids were blended in accordance with the response surface methodology to prepare acidic agents. The normal clay was then mixed with the prepared solutions after drying in a laboratory oven. The set-up provided controllable conditions for producing nano-porous powders for which the residence time and temperature were changed. The removal efficiency of the treated powders was assessed by defining an adsorption ratio and determining the optimal composition for acidic agent. Based on the statistical theory and experimental data, nitric acid is a suitable agent for manufacturing porous material to remove methylene blue from wastewater. In addition, the Brunauer-Emmett-Teller method, X-ray diffraction and Fourier transform infrared spectroscopy techniques were applied to identify the structural changes. The experimental data obtained from the batch tests were analysed by a new kinetic model which predicted the data variation with higher regression coefficients and lower relative errors. The proposed procedure can be an important tool in optimising the acidification conditions for manufacturing a nano-porous powder with maximal removal efficiency.


One of the tourism object that have special attraction is Yogyakarta, Yogyakarta is typically able to deliver persistence of Sultanate Ngayogyakarta customs and uniqueness of Javanese culture that is able to attract public attention, so it make this city as a leading cultural tourism destination in Indonesia and could boost the development of small and medium industries with the growth of creative industries in it. By carrying the slogan "Never Ending Asia", Yogyakarta could become a thriving tourism business. Law No. 15 of 2001 on Marks have not set about city branding as one of the classes in the right brand the ca be registered to the General Directorate of Intellectual Property Right. This can be seen from the absence of definition in general terms or any information on the explanation of the Act which states city branding. Jogja: Never Ending Asia, only a brand image in the province of DIY and do not register at the Directorate Genera of Property Rights as the concept of brand in the Law No. 15 of 2001 on Branding. Viewing the conditions of tourism Indonesia and Yogyakarta that is very strategic, advice can be given for the advancement of tourism in Indonesia is to reinforce the definition of City Branding itself, namely by making changes to the Law No. 15 of 2001.

As scientific workflows increasingly gain popularity as a means of automated data analysis, the repositories such workflows are shared in have grown to sizes that require advanced methods for managing the workflows they contain. To facilitate clustering of similar workflows as well as reuse of existing components, a similarity measure for workflows is required. We explore a new structure-based approach to scientific workflow similarity assessment that measures similarity as the overlap in local structure patterns represented as n-grams. Our evaluation shows that this approach reaches state-of-the-art quality in scientific workflow comparison and outperforms some established scientific workflow similarity measures.


In this paper, we propose a federated learning(FL)-based collaborative anomaly detection system. This system consists of multiple edge nodes and a server node. The edge nodes are in charge of not only monitoring and collecting data, but also to train an anomaly detection neural network classification model based on the local data. On the other hand, the server aggregates the parameters from the edges and generates a new model for the next round. This system structure achieves light weight transmission between the server and the edge nodes, and user privacy can be well protected since raw data are not communicated directly. We implement the proposed scheme in the practical system and present experimental results that demonstrate results competitive with those of state-of-the-art models.


Abstract We give a systematic approach to compute certain sums of squares of Fibonomial coefficients with finite products of generalized Fibonacci and Lucas numbers as coefficients. The technique is to rewrite everything in terms of a variable q, and then to use generating functions and Rothe's identity from classical q-calculus.


This paper discusses the use of the structural Eurocode EN 1992-1-2 for assessment of the residual strength of concrete members after exposure to fire. This code deals with the fire resistance of reinforced concrete structures during fire and provides a strength decrease formulation as a function of the temperature, as well as the thermal properties of calcareous and siliceous concrete. In EN 1992-1-2, simplified methods are described to calculate the fire resistance, such as the 500°C isotherm method. This method takes only the concrete heated below 500°C in account and considers the strength decrease of the reinforcement at the actually obtained temperature during fire. However, after fire exposure the concrete strength will reduce further. First, when the concrete is cooled with water by the fire brigade, additional strength losses of up to 30 % were noticed in experiments performed by the author. Second, experiments show that storage of the concrete in air and in water may result in additional strength losses of up to 20 % in the first weeks after cooling, after which slow recovery is possible. These additional residual strength losses are not considered in the EN 1992-1-2, since the models are intended for reinforced concrete during a fire. In this paper the residual bearing resistence of a pretensioned small beam, heated during a real fire and afterwards submitted to a static loading test is calculated. In this experiment the residual strength losses are incorporated and the results show adequate correspondence with the experimental test results.


Disclosed are a process and apparatus for selective catalytic reduction of NO. The process is enabled by passing a heat exchanger section, Such as an economizer, of the boiler in advance of an SCR unit at low load conditions to enable NO, reduction even at low loads using urea instead of ammonia. In a preferred form, under high load conditions, the bypass can be almost fully closed and the economizer can be operated normally without excessively cooling the combustion gases, using only a portion of bypassed gases which are hot enough to decompose the urea into its active components including ammonia.
