At present, the mines in our country gradually shift from the shallow mining to the deep mining, but the deep well floor is particularly serious hazard by high pressure underground water.This article considers the high pressure underground water as three-dimensional transient flow, sets up mechanical model by combining mechanical knowledge and to analyze the destructive action on floor from two aspects. On the one hand, researching the impact destruction of high pressure water at different positions of floor ; the other hand, to analyze mechanical function on fracture development from high pressure water.


Since Sino-Japanese War, Japanese was trying to make then Chosun their military supply base to realize their ambition of imperialism. In this regard, Japan exerted the efforts to subjugate Koreans to be the voluntarily faithful people of Japanese King through the Empire Subjectized Education Policy. In terms of this efforts, National theatrical play contests were held and many play performers brought to show the works containing the Japanese intention. Due to this history, the theme of national theatre is rarely discussed about for so long time. Considering this historical disgrace, this article examines the historical meanings through the mother's image taking the lead at home where husband does not exist. Dramatized works showed the different images between the uneducated poor mother and educated rich mother. Japanese stretched the different strategies according to each social hierarchy, to complete their responsibilities making Koreans faithful people of Japan. They maximized the motherhood by giving the incomplete body to the poor and ignorant 'Mother' image. For example, a mother without a ann in such play raises the son in the remote mountain village to be the leader of coal mine. And she committed suicide for the guilty for daughter. The mother's past is heard only through her statement without any embodiment, and her figures is the mechanized human being. The false image invented the illusion not the reality to mislead the audiences. This mother figure providing the mechanized labor forces and choosing the death to the weak and senile herself is the expression desired by Japanese toward people of Chosun. On the contrary, educated and rich 'mother' indicates the gentle enlightenment attitude apparently. The play has dramatized this mother in detail as the modernized figures still based on the traditional mother who provides the labor forces or activities only in the private areas other than the public areas. On the stage, this mother spends time for herself not being dedicated only to making a living and rearing of children. As above stated, Japanese has tried to create the different phase of 'Mother' image in the theatrical play works according to the different social hierarchy. However, all the mother figures are the same in being consistent with the mother figure rejecting the sleeping and rest to move diligently just like a machine.


The invention relates to a method for determining the flow rate of a fluid through a pump, in particular by a driven by a permanent-magnet rotating field-driven synchronous motor pump, wherein in the pumping operation of the engine from the electric / electronic drive at least intermittently, in particular periodically turned off in the off state in the engine induced voltage (1, 2, 3) is detected and from the detected induced voltage (1, 2, 3) the flow rate of the fluid is determined. The invention further relates to a pump for performing the method.


Four new synonyms are proposed, based mainly on the study of type material: Fannia berolinensis Hennig, 1955 = F. limbata (Tiensuu, 1938); F. coracula Collin, 1958 = F. fuscitibia Stein, 1920; F. hylemyiaeformis Ringdahl, 1952 = F. brinae Albuquerque, 1951; and F. spinosa Karl, 1923 = F. sociella (Zetterstedt, 1845). F. fuscitibia Stein is now shown to have a Holarctic distribution, and the known distribution of F. limbata (Tiensuu) is extended as far south as southern Moravia. Lectotypes are designated for F. hylemyiaeformis Ringdahl and F. spinosa Karl.

The woody and shrubby plants species composition and vital status at the territory of Krasnoyarsk Central Park were studied. The purpose of the work is to determine the tree and shrub species composition at the territory of the Central Park, to assess their vital status, to study the arboriflora structure and biodiversity, to identify dominant and single species, to give recommendations for improving the species composition and plantings quality. The studies were carried out in August 2021. The assessment of the species diversity, vital and sanitary condition of the park's tree and shrub vegetation was carried out by the method of a complete enumeration of trees. The planting vital index determination was carried out using the generally accepted method of visual assessment of tree and shrub vegetation. It has been established that the Central Park arboriflora is represented by 86 species of plants, including: 39 species of trees, 46 species of shrubs and 1 species of vines. Arboriflora consists of 4470 plant (4133 trees, 337 shrubs), growing in the alley cropping, group planting, solitaires, boskets (total length 582 m) as well as hedge grow (50 m). The plantings vitality index is 1.99, which corresponds to a weakened or slightly damaged stands. The arboriflora structure was determined, its features were identified. The species that make the main contribution were identified. The most stable and weakened species of the park's arboriflora were identified. Recommendations to stand developing of Krasnoyarsk Central Park were formulated based on the obtained results. It is advisable to apply park reconstruction proposals for urban spaces landscaping in similar environmental conditions. plants, life status composition.


We consider binary classification problems with positive definite kernels and square loss, and study the convergence rates of stochastic gradient methods. We show that while the excess testing loss (squared loss) converges slowly to zero as the number of observations (and thus iterations) goes to infinity, the testing error (classification error) converges exponentially fast if low-noise conditions are assumed.


Undergirded by a theoretical framework, which focuses on the important role of social context, this article focuses primarily on the cultural, institutional, and individual factors explaining how Chicanas fare in academia. To what extent are the experiences of Chicanas exemplary in suggesting similar issues for African-American, Asian, and American Indian women? What strategies have Chicanas employed to help them negotiate the new and ever-changing aspects of academic life? Based on research with 30 Chicana faculty, this article provides compelling answers to these important but unanswered questions.


Myelofibrosis (MF) is the deadliest form of myeloproliferative neoplasms (MPN). The JAK2V617F mutation has been found in ~50% patients with MF. Ruxolitinib, a JAK1/JAK2 inhibitor, has been approved for treatment of MF. However, Ruxolitinib treatment has failed to induce disease remission or cure fibrosis. Therefore, there is a need to develop novel targeted therapies for MF. We found that PIM1 expression is significantly increased in mouse and human MPN/MF hematopoietic progenitor cells. Moreover, PIM1 knockdown markedly inhibited proliferation in JAK2V617F-expressing cells but not in wild-type JAK2-expressing cells. In this study, we investigated the efficacy of the second-generation pan-PIM kinase inhibitor, TP-3654, in hematopoietic cells expressing JAK2V617F and in a murine model of MF. We found that TP-3654 (0.5-1.0 μM) treatment significantly reduced proliferation of murine Ba/F3-EpoR cells expressing JAK2V617F or human JAK2V617F-positive HEL and UKE-1 cells. TP-3654 Treatment also resulted in marked apoptosis in Ba/F3-EpoR-JAK2V617F, HEL and UKE-1 cells but not in wild-type JAK2 expressing Ba/F3-EpoR cells. Additionally, TP-3654 and Ruxolitinib synergistically induced apoptosis in JAK2V617F-expressing hematopoietic cells. Furthermore, TP-3654 significantly inhibited MPN/MF CD34+ hematopoietic progenitor colony growth. We previously reported the generation of JAK2V617F knock-in mice. Whereas heterozygous JAK2V617F knock-in mice exhibit a polycythemia vera phenotype, mice expressing homozygous JAK2V617F rapidly develop high-grade MF. We have utilized the homozygous JAK2V617F mice to test the in vivo efficacy of TP-3654 alone or in combination with Ruxolitinib against MF. Treatment of TP-3654 alone significantly reduced the increase in white blood cell (WBC) and neutrophil counts as well as spleen size in mice expressing homozygous JAK2V617F compared with vehicle treatment. Combined treatment of TP-3654 and Ruxolitinib almost completely normalized the WBC and neutrophil counts and the spleen size in homozygous JAK2V617F mice. Histopathologic analysis revealed marked reduction in fibrosis in the bone marrow and spleens of TP-3654-treated mice whereas Ruxolitinib treatment did not significantly reduce fibrosis. Combined TP-3654 and Ruxolitinib treatment almost completely eliminated fibrosis in the bone marrow and spleens of homozygous JAK2V617F mice. TP-3654 treatment was well tolerated and did not cause any significant toxicity in wild type mice. RNA-sequencing analysis on purified LSK (Lin-Sca-1+c-kit+) cells from these drug-treated mice revealed that the genes related to TNFα and WNT signaling pathways were significantly down-regulated by treatment of TP-3654 alone or TP-3654 and Ruxolitinib combination compared with vehicle. Overall, our results suggest that TP-3654 alone or in combination with Ruxolitinib may have therapeutic potential for treatment of MF. Citation Format: Avik Dutta, Dipmoy Nath, Yue Yang, Golam Mohi.

: Classroom discourse has aroused interest among scholars and educators (Deroey, 2015; Mauranen, 2012; Hyland, 2010), particularly the use of metadiscoursal markers. However, little attention has been paid to these features when they are supported by machine translation (MT) engines in content and language integrated learning (CLIL) contexts. The aim of this paper is to describe the use and frequency of hedges and boosters employed in the fields of


Since the late 1980s Brazilian local politics has been the site of political innovations and new democratic processes. One particularity of local politics in Brazil is the active involvement of social movements in the contestation of public social goods and services for the low income classes and their assertion of a political identity. This paper analyses urban and rural movements involved in local politics and how they have contributed to democratization and social change in Brazil at the municipal level. It asserts that social movements are influential in local politics, especially concerning municipal policies and processes to improve democratic participation.


The p53 tumour suppressor protein plays a crucial role in regulating cell growth and death in response to various types of cellular stress. The loss of its function is the most common event leading to the development of cancer. In normal cells, p53 is present at low levels because the protein is rapidly degraded by the ubiquitin-mediated proteasome pathway following the synthesis. Stress-induced signals inhibit p53 degradation, leading to its rapid stabilization and accumulation in the cell, and followed by its activation by mechanisms including phosphorylation and acetylation. The complexity of the pathways regulating p53 stabilization and activation as well as possible p53 activation in response to small chemical compounds used in certain experimental anti-cancer therapy approaches are discussed in this review.


This study investigated the predictive strength of Transformation models of continuous assessment scores in English Language, Mathematics, Integrated Science and Social Studies in Secondary Schools in Nigeria. The study employed survey and cross-sectional design. The sample consisted of 2,520 JSS III students selected from 36 secondary schools in 18 Local Government Areas based on multistage sampling technique. Data were collected directly from the Ministries of Education, Continuous Assessment Units with a proforma. The data collected were subjected to inferential analysis using regression. The results showed that the overall best predictor of comparability indices was True score followed by Predictive true score, T-score, derived true score while Z-score was the least. Based on the findings, it was recommended that secondary school teachers should be trained on the procedure to transform continuous assessment scores. True score should be used to standardize continuous assessment scores before finally used by examining bodies and continuous assessment units of Ministries of Education. Keywords : comparability indices, continuous assessment, predictive true score, true score, derived true score


This analysis of the extent to which Roman domination impacted on and changed the religion of north-western Hispania is based upon an analysis of many inscriptions, which reveal the names of indigenous and classical deities, including those with indigenous epithets. Elizabeth A Richert argues that this evidence indicates that local residents worshipped 'a bewildering array' of deities, many of which were linked to local people and sacred places and, therefore, were very different from the Roman pantheon of gods. The local mountains and rock formations would have had more influence on local religion than Roman occupiers; locals selected which of the new Roman deities fitted in most suitably with their own religious needs. Much of the book comprises a catalogue of inscriptions.


Abstract— The defects of flat‐panel liquid‐crystal display are usually not uniform, and the defects are called as "Mura." There are many factors that cause the Mura phenomenon. At present, the human eyes define the seriousness of Mura, and different operators define the same Mura phenomenon with different meanings. For this reason, there have been many conflicts between the suppliers of flat‐panel liquid‐crystal display and customers. In order to solve the conflicts between the suppliers and customers, some researchers proposed a regression equation for the luminance contrast threshold and the size of Mura. In addition to the effect of Mura size on luminance contrast threshold, this study investigated the relationship between other factors and luminance contrast threshold. An analysis of the results show that Mura size, polarity of Mura, Mura position, and different color backgrounds significantly affect the visual contrast threshold. However, polarity did not significantly affect visual contrast threshold. In this study, it was found that Mura size was more important than the other factors for visual contrast threshold. The results of this study is expected to be referenced for inspection by the LCD industry.


The bainitic transformation in a Cu-Zn-Al-Mn alloy has been examin-ed with TEM. The results show that the stacking faults and also the bainitic mi-drib are found at the beginning of bainite formation in the alloy. The stack-ing fault planes can pass continuously through the midrib in bainite. The growthledges occur at the broad faces and rims of bainite. The broad and narrow faces ofthe ledges are parallel to the fault plane and habit plane respectively. Both theirMiller indices are {110}_(B_2). The moving direction of ledges is parallel to the faultplane. It may be deduced that bainites in a Cu-Zn-Al-Mn alloy are initially form-ed by shear and the process of growth are governed by propagation of fault planes.


Aims: We wanted to study the outcome of bone transport by IlizarovOs method in simple and complicated gap non-unions where other conventional methods have little role to play. Methods: Sixty-six consecutive patients with an age range of 23–64 years (58 males and 8 females) were included in this study. Forty-four patients (67%) had associated problems like infection, deformity and shortening along with gap non unions of varying length. All the patients were treated with ring þxators and the principles of IlizarovOs treatment were adopted. Corticotomy was carried out in all the cases. Appropriate arrangement of apparatus assembly was done according to the requirement of individual gap non-unions. Follow up ranged from 6 to 46 months. Results: In all but three cases, union was achieved along with satisfactory correction of other associated problems. In one case the patient had previously undiagnosed hypothyroidism and showed signs of callus at corticotomy site after treatment with thyroxine. This patient lost to follow-up. Two other cases needed further surgery (IlizarovOs ring þxator). In one case, cancellous bone grafting had to be carried out. In six tibial gap non-unions, residual equinus deformity persisted. Conclusions: IlizarovOs method of bone transport is quite effective in treatment of gap non-unions associated with complex problems, where other methods have proven to be less successful.


This article examines the problem of institutional development of the Orthodox Church in Subcarpathian Rus' in the second half of 1926. The author examines the diplomatic negotiations between the governments of Czechoslovakia (hereinafter - CSR) and the Kingdom of Serbs, Croats, and Slovenes (hereinafter - KSCS), with the leadership of the Serbian Orthodox Church (hereinafter - SOC) and representatives of the Orthodox communities in Subcarpathian Rus'. Particular attention is paid to the persistent demands of the SOC to preserve its rights to elect and appoint bishops. Based on a study of archival documents, the author established that the government in Prague, following the Austro-Hungarian policy, sought to take control of the selection of candidates and the approval of bishops. The article summarizes new material on the research topic and introduces many documents from the Serbian and Czech archives into scientific circulation. Among them are decisions of the Synod of the SOC, internal correspondence of the Synod with the Council of the SOC, personal correspondence of bishops with the patriarch and leaders of the Orthodox movement in Subcarpathian Rus', diplomatic correspondence between Czechoslovakia and KSCS, secret correspondence sent in Belgrade with the Prague Ministry. The article also examines the critical stages of agreeing on the candidacy of the SOC delegate for Orthodox communities of Serbian jurisdiction in the province, who was instructed to complete the development of the diocesan statute and achieve official recognition of Orthodox in the country. The opinion that the most acceptable candidate for Prague was the sinkel Damaskin (Grdanichka), the ordination of which was postponed by the dignitaries of the SOC, is substantiated. Instead, Bishop Irenaeus (Chirich) of Novosad-Bachka was delegated to Subcarpathian Rus', an experienced church figure who managed to prepare the ground for the institutional completion of the Orthodox Church in the autonomy.

Vexillology—the study of flags, often overlaps with vexillography—the design of flags. It's no wonder, since most of us who look at thousands of flags in the course of our study cannot help but form opinions about their design as well. The flag community accepts this shift from the descriptive to the prescriptive as long as the boundary is clear: those who document flags should accept all flags as meriting study without regard to their quality, while those who seek to create or improve flags should disclose that their agenda is not scholarly but activist.

For an underdeveloped and developing nation uplifting economy up to expectation is a challenge. Raising economy in such context must have accelerated growth and development that improves quality of life. Small and medium scale enterprises are provisions for fast growth and fulfillment of economic prosperity by any nation. The economy depends on its working population for economic growth and development. The economic reform in the early 1990s in Nepal pulled the attention of the private and joint investment to seek the financial sector. National and regional development strategies, the strategies towards poverty reduction of individual member countries should underline the importance of private sector promotion. In this research A total of 200 copies of the questionnaires to be administered. The instruments to be used are gather information for this study includes questionnaires and interview. Two different statistical methods are to be employed to analyze data for the study; the tools are simple percentage and chi square test. keywords: youths, employment, economic growth, small and medium enterprises, Nepal.


Specific birth‐related fractures have been studied; underestimates might be a problem. We aimed to assess all fractures diagnosed as birth‐related as well as other neonatal fractures.


Black persons of sub-Saharan African descent differ from white persons and other populations in cultural, social, and psychological roots, as well as in biological characteristics (1, 2). Although the black population is heterogeneous, hypertension investigators have considered black persons a distinct biological entity when studying environmental and genetic factors that might explain the observed group differences in risk for hypertension and response to treatment (1, 3-5). Not only are black persons more likely to develop hypertension, but compared with hypertension in other ethnic groups, the disorder in black patients is often more severe, more resistant to treatment, and more likely to be fatal at an earlier age (1, 3). Thus, hypertension seems to be a more aggressive disease in black patients; this has important implications for the choice of an antihypertensive agent (1). However, there is no consensus on the optimum drug treatment strategy for hypertension in black patients (1, 6-11). Current guidelines offer different opinions (1, 7-11) and either contain no specific treatment strategies for black patients (7), describe strategies without a specific drug of choice for first-line treatment (8), or advise the use of a specific drug, usually a diuretic, as first-line treatment (1, 9-11). We conducted this systematic review to critically assess the existing evidence on the efficacy of all commonly used antihypertensive drugs in reducing blood pressure and morbidity and mortality outcomes in this population. Methods Literature Search We sought to identify all trials, published or unpublished, that considered the effect of different classes of antihypertensive drugs in hypertensive black adults. To identify relevant trials, we searched MEDLINE, EMBASE, LILACS (Literatura Latino-Americana y del Caribe en Ciencias de la Salud), African Index Medicus, and the Cochrane Library from their inception through November 2003 and searched PubMed from September 2003 through March 2004. We also searched the Database of Abstracts of Reviews of Effects, Best Evidence, and Reviews in Progress (all from the United Kingdom) and hand searched Index Medicus from 1953 backward. Finally, we searched for trials by using references from textbooks, narrative reviews, and systematic reviews; by contacting experts and pharmaceutical companies; and by searching the Internet. We did not restrict the searches to any specific languages. Detailed search and retrieval strategies have been published elsewhere (12, 13). Selection Criteria To assess the blood pressurelowering efficacy of the drugs, we included randomized, placebo-controlled trials of at least 2 weeks' duration that compared single drugs with concurrent placebo treatment and provided quantitative data on effects on systemic arterial blood pressure (as a continuous or dichotomous measure) in black adults. We also determined whether an increase in drug dose was needed for adequate blood pressure control. To assess the effects of drugs on morbidity and mortality, we included randomized, controlled trials that lasted at least 1 year, that used single drug treatment or compared single drugbased combinations of antihypertensive drugs with other combinations or with concurrent placebo treatment, and provided separate quantitative data on morbidity or mortality in black adults. We further assessed whether drug dose was increased or other drugs were added to reach the blood pressure goal. In addition, we evaluated adverse effects; discontinuation of drug therapy; and dropouts due to lack of effect, adverse effects, or other reasons, as defined by the authors. Trials that considered oral treatment with diuretics, calcium-channel blockers, centrally acting agents, peripheral adrenergic neuron antagonists, -blockers, -blockers, single agents with combined - and -blocking activity, direct vasodilators, angiotensin-converting enzyme (ACE) inhibitors, or angiotensin II receptor blockers were eligible for inclusion. We included only trials that reported the number of black patients treated (per protocol or intention-to-treat analysis). Data Assessment At least 2 reviewers independently assessed each eligible study. Disagreement was resolved through final discussion. Investigators of each study were contacted twice to obtain missing information. We assigned a Jadad score ranging from 0 to 5 points to the included trials according to whether the investigators described the study as randomized and double-blind, reported the methods used to randomly assign patients and blind the intervention, and reported the number of withdrawals and dropouts and the reason (14). The score was calculated on the basis of separate descriptions of withdrawals and dropouts for black persons. Other quality aspects addressed were as follows: whether the study assessed the minimum drug dose needed to reach a maximum antihypertensive effect (15), whether outcome assessment was blinded, and whether the report described adverse effects. Statistical Analysis We performed the statistical analysis using Cochrane Review Manager (RevMan) software, version 4.2 (Cochrane Collaboration, Oxford, United Kingdom). When studies did not provide SDs, we imputed them per drug type by using the available SDs for each drug class (16). Quantitative analysis of outcomes was based on intention-to-treat results (primary) and per protocol analysis (secondary). Our measure of effect for each study was difference in means (in mm Hg) for systemic arterial blood pressure (continuous measure) and relative risk for dichotomous data. When a study provided only the differences between the drug and placebo groups, we entered data in RevMan as drug results, with a nil for placebo results. We included data from the first part of crossover studies when such data were available; if not, we included the data these studies provided. Before applying approximate chi-square tests for heterogeneity, we clinically assessed studies for heterogeneity in patient characteristics, interventions, and outcomes. We used I2 statistics to quantify the proportion of total variation in the estimates of treatment effect that was due to heterogeneity (17). We then explored the sources of the heterogeneity and decided whether we should aggregate the studies. When we aggregated studies, we used the random-effects model. We did not aggregate results with a high variation across studies because of heterogeneity (I2 75%) (17). We performed sensitivity analyses by reanalyzing data using fixed-effects models and by reanalyzing data after excluding studies with imputed SDs, crossover studies, and studies that used per protocol analysis. We predefined the following subgroup analyses (13): patients with differential severity of hypertension before treatment allocation (18); studies conducted in Africa compared with U.S. and Caribbean studies (since European admixture of up to 25% has occurred in the black population in the Americas [19], possible genetic influences on drug responses might be stronger in African patients); and outcomes based on sex. Data Synthesis Trial Retrieval Full reports or abstracts from more than 2900 references of papers yielded 30 trials that involved 53 interventions, 8 classes of antihypertensive drugs, and 20006 black patients. Blood pressure was the main outcome measure in 26 of these trials (20-47) (Table 1). Figure 1 shows the trial flow and reasons for exclusion of trials. Table 1. Characteristics of Included Studies with Blood Pressure Outcomes Figure 1. Trial flow. SHEP Methodologic Quality of Included Studies Jadad scores ranged from 2 to 4 (median, 3) in studies with blood pressure outcomes (Table 1) and from 3 to 5 in studies with morbidity and mortality outcomes. The Systolic Hypertension in the Elderly Program (SHEP) study lost 2 points1 for method of randomization (which we could not retrieve) and 1 for withdrawals and dropouts; the Losartan Intervention For Endpoint reduction in hypertension (LIFE) study and the Antihypertensive and Lipid Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) both lost 1 point because of withdrawals and dropouts; the African-American Study of Kidney Disease and Hypertension (AASK) achieved the maximum score of 5 (48-61). Studies with blood pressure outcomes used preset doses and did not report whether they assessed the minimum dose needed to reach a maximum antihypertensive effect in black people (15). No trial reported subgroup analyses based on baseline blood pressure. Three trials reported blinding of assessment of outcome (49, 53, 57). Adverse effects were reported in 12 of 26 studies that had blood pressure outcomes, and dropouts and withdrawals were described in 14 studies (total rates, 0% to 52%; median, 14%). Two of the 4 trials with morbidity and mortality outcomes described adverse effects (57, 61), and 1 reported the dropout percentage for black patients (31%) (57). Seventeen trials used intention-to-treat analysis, including all trials that had morbidity and mortality outcomes; 13 trials used per protocol analysis (Table 1). Seven studies were crossover studies (21, 29, 34-37, 43), and 1 provided separate data on the first part of the crossover study (43). Trials with Blood Pressure Outcomes Blood PressureLowering Efficacy The trials with blood pressure outcomes included patients with baseline systolic blood pressure (SBP) up to 225 mm Hg and diastolic blood pressure (DBP) of up to 155 mm Hg. The median duration of active treatment was 8 weeks (range, 2 to 52 weeks). With the exception of -blockers for SBP, all the reviewed antihypertensive drugs were more effective than placebo in reducing SBP and DBP as continuous measures, although the effect of -blockers on diastolic blood pressure was of marginal significance (Figures 2 and 3). Four trials showed a tendency toward an increase in SBP with the use of -blockers (29, 35, 39, 43), and trials that reported results of individual patients (29, 34) f


Arsenic (As) contamination of groundwater is now well documented across the globe. Geological environments similar to those in which high levels of dissolved As occur elsewhere are common in Ireland (e.g. sulphide-bearing volcanic & sedimentary units), yet reliable data at the μg/L level for As in groundwater are sparse. An improved understanding of As occurrence and its sources is important in Ireland because up to 20-30% of public drinking water supplies are provided by groundwater, and an additional 170,000 small private supplies are in use which remain largely unregulated. Recent investigations have highlighted As to be a contaminant of emerging concern in some Irish groundwaters that have As values exceeding the 10 μg/L World Health Organisation (WHO) limit. The work presented here will focus on specific cases with an emphasis on the geological and mineralogical sources of arsenic.


The fourth industrial revolution and the digital transformation that comes with it is making manufacturing processes more effective, easier to control and optimise. It allows manufacturing businesses to gradually increase productivity and reduce resource use. Digitalisation is fundamentally changing all social segments and the economy; therefore, digitalisation does not solely affect the manufacturing industry but also the macroeconomy and public employment of the country. The current global pandemic has played a major role in encouraging the Lithuanian manufacturing industry to search for new ways to reduce manual human labour in the manufacturing process and to optimise it. The industrial digitalisation revolution is undoubtedly going to result in multiple opportunities for various parts of the society, however the unprecedented speed of these changes is going to interfere with the economy and labour market on a broader scale. Thus, it is important to attempt to mitigate the risks of jobs being replaced by technologies, polarisation of the labour market and increasing inequality among people and regions to successfully introduce digital technologies in manufacturing businesses. The aim of this article is to reveal the predicted trends, benefits, and challenges in development of digitalization of Lithuanian manufacturing industry. This is achieved by systemic analysis of literature and statistical data, and data visualisation.


The Cr, Ni, Cu, As, Se, Cd and Pb in AC and PP tow samples were digested by HNO3/H2O2 with four steps of different microwave intensities and durations, and then determined by ICP-MS. The duration for the fourth step of digestion was optimized. The results showed that the optimal condition for the fourth step of digestion was 190℃ for 20 minutes. The recoveries of the elements were in the range of 86.38% to 117.2% with RSD of 25% and limits of detection of 25.20 to 245.1ng/L. Se and Cd were not detectable in the two tow samples.


This study was developed to examine the effect on environmental enrichments adapted for wolverines (Gulo gulo) in two Swedish zoos. The wolverine is an opportunistic omnivore that is part of the Swedish fauna and commonly kept animal in Swedish zoos. Being one of the less researched of Swedish carnivores, compared to wolves (Canis lupus) and bear (Ursus arctos), the wolverine is an interesting creature to develop the knowledge of. With zoos working hard to reassure their animals have an increasing welfare, the importance of enrichment and well-designed enclosures becomes more and more evident. Therefore this study was designed to understand if there is a connection between environmental enrichment and the designs of the enclosures of the wolverine. Four different enrichments was tested on four adult wolverines. The study took place during five days per zoo. The enrichments was set out during four of the days, with the first day kept clear to observe the behaviour without the impact of enrichment. The wolverines was observed each day before and after the enrichment was placed into the enclosures to compare the behaviour with and without the influence of the enrichment.
There was a very clear variation in the behavior of the wolverines. Each wolverine showed various behaviour when presented to the enrichment. Each type of enrichment also had impact on the reactions from the individuals. This may be an indication of an ability to select which enrichment that's the most intriguing, but it may also be an effect from earlier experiences with enrichments in the different zoos. Another alternative is that this indicates the differences of the four individuals in this study. Due to the low amount of animals observed in this study it's hard to apply the collected results on a larger group of individuals or on the entire species. However this material is a good basis to use for more projects on wolverines in zoos.


This study presents a practical solution for data collection and restoration to migrate a process written in high level stack-based languages such as C and Fortran over a network of heterogeneous computers. We study a logical data model which recognizes complex data structures in process address space. Then, novel methods are developed to incorporate the model into a process and to collect and restore data efficiently. We have implemented a prototype software and performed experiments on different programs. Experimental and analytical results show that (I) a user-level process can be migrated across different computing platforms, (2) semantic information of data structures in the process's memory space can be correctly collected and restored, (3) the costs of data collection and restoration depend on the complexity of the logical model representing the process's data structures and the amount of data involved and (4) the implantation of the data collection and restoration mechanisms into the process is not a decisive factor of incurring execution overheads; with appropriate program analysis, we can achieve practically low overhead.


Multibody and total nonadditive energy components have been calculated for (H2O)4 to (H2O)48 clusters chosen to determine the effects of different factors upon the interaction, using the water–water potential of Campbell and Mezei. For the first time, the total nonadditive energy of ice Ih has been calculated within the context of this model and cluster results have been used to obtain estimates for the three‐ and four‐body components. The magnitudes of the four‐body components for many clusters and for ice Ih have been shown to be in the energy range required for possible effects upon preferred orientations. Comparisons with the triple‐dipole dispersion energy have confirmed the greater importance of the induction contribution. When the cooperative reinforcement of the induced dipole fields, hyperpolarizabilities, and field gradients are neglected, the induced dipole energy has been shown to be strictly two and three body. The relative efficiencies of three‐body and self‐consistent calculations of the in...

Residential energy disaggregation is a process by which the power usage of a home is broken down into the consumption of individual appliances. There are a number of different methods to perform energy disaggregation, from simulation models to installing "smart-plugs" at every outlet where an appliance is connected to the wall. Non-Intrusive Load Monitoring (NILM) is one such disaggregation option. NILM is widely recognized as one of the most cost-effective methods for gathering disaggregated energy data while maintaining a high level of accuracy. Although the technology has existed for many years, the adoption rate of NILM, and other devices that disaggregate energy, has been minimal. This thesis provides details on the potential benefits, both for the customer and utility provider, associated with furthering the adoption of NILM devices and obtaining the disaggregated appliance level energy-use. A broad overview of potential benefits is presented; however, the primary goal of this thesis will be to investigate two benefits of NILM in detail: overall household energy reduction and targeted demand response. First, installation of a NILM device can provide electricity customers information that allows them to become more aware of their energy consumption, and thereby, more energy efficient. A study was conducted that looked at the electricity consumption of 174 homes that were using a passive NILM device in their home. This NILM device provided immediate feedback on the power consumption for a portion of the home's appliances via smart-phone application. The homes reduced their monthly energy consumption by an average of 2.6 3.1% after the NILM installation. This was validated by a number of analysis methods returning


Mastering deep space is one of the main stages in the development of science as a whole. Considering the space industry, all the most modern technologies of mankind are taken. One of the most important tasks in space exploration is the implementation of sustainable information exchange between different segments. Special attention is paid to systems for automatic identification of objects, which in turn contribute to optimizing the time allotted for clear positioning of objects for organizing life activities, defining specifications, as well as making managerial decisions aimed at planning and efficient management of material flow to support vital functions and fulfill strategic tasks of astronauts . The purpose of this article is to study the technology of radio frequency identification, as applied to the space industry, as well as modeling the process of information exchange of various segments, to identify the optimality of algorithms in the development of data encoding methods in the space industry. The article discusses the tasks of material flow identification, standardization based on CCSDS 881.1-B-1 (Spacecraft Onboard Interface Services-RFID tag encoding specification) standart and various versions of regulatory documents. The task of information exchange between different segments space station based on RFID technology is not completely solved. Due to the presence of various segments, testing for possible errors in the information exchange between segments is necessary and very important. The article presents the solution of the cargo identification problem, presents the structure of the label fields, presents the choice of symbol libraries and models, and presents mathematical coding model.

On results, one can determine the real technical requirements for information exchange and identification technology based on radio frequency technology.


Abstract : A series of chemical and physical methods, previously developed for use in the study of the constitution of coals, has been applied to the definition of structural parameters for thirteen tar and pitch samples which have a wide range of properties and which are of interest in the fabrication of graphite bodies. Information obtained on the molecular size and composition indicates the presence of polycyclic compounds with a high degree of aromaticity. Evidence also points to the importance of large aromatic clusters. (Author)


Tasks scheduling in cloud computing environment plays an important role for both Cloud Service Providers (CSPs) and the users of the services provided. Therefore, designing an efficient task scheduling algorithm, which fulfill the requirements of CSPs and their clients is essential. Several scheduling algorithms are proposed by various researchers for task scheduling in cloud computing environments. This paper introduces an alternative method for cloud task scheduling problem, which aims to minimize makespan of executing a number tasks on different Virtual Machines (VMs). This method is based on Bumble Bee Mating Optimization (BBMO) algorithm. BBMO is powered by the features of swarm intelligence and local search algorithms. The performance of BBMO is compared to two existing algorithms, Honey Bee Mating Optimization (HBMO) algorithm and Genetic Algorithm (GA). Finally, we analyze the performance of the proposed algorithm with other two algorithms using different scenarios of experiments. The results show that the proposed algorithm (BBMO) outperforms other algorithms.


sions policies affect their own legitimacy within our society. The public discussions of the affirmative action litigation brought attention to many featuresof university admissions that can inspire resentment within the largersociety-from earlydecision processes to preferences for so-called legaciesto high tuition rates to reliance on test scores. The interest in ensuring that our important societal institutions hold a measure of democratic legitimacy will likely promote an ongoing discussion of how and whether those features serve universities' institutional missions and meet the needs of our society as a whole. The litigation about the University of Michigan's admissions policieswas ultimately important because it implicated values that shape our national identity. Over the course of the litigation we learned how to speak with greater clarity about those values, and about the tension between them. Whether or not the tension is ever fully resolved,understanding its structure will surely help us to more intelligently confront the challengesahead. The Educational Value of Diversity


Abstract Intestinal absorption of corn oil and beef tallow was studied in White Leghorn male chicks during the periods of 2 to 7 and 8 to 15 days of age. Absorption of both fats was less at the earlier age. The corrected absorbability of corn oil increased from 84 to 95%; that of beef tallow from 40 to 79%. With both dietary fats, the greatest amount of fat appeared in the excreta at 5 and 7 days of age and then decreased rapidly within a 2-day period. Absorbability values for corn oil and tallow during the 8 to 15 day period agreed with generally accepted values found in the literature, while those for the 2 to 7 day period were lower. These results show that the newly hatched chick does not have full physiological capacity for fat absorption. However, this appears to develop rapidly after the first few days of life.

Balakrishnamurti, T. S., 197S. Inorganic and organic sources of nitrogen and phosphorus as fertilizers for coconut Ceylon Cocon. Q., 26, 104—107 Results of a long term experiment to investigate the performance of inorganic and organic sources of nitrogen and phosphorus as fertilizers for coconut on a sandy loam soil in the Intermediate Zone (rainfall) are presented and discussed. The inorganic sources were sulphate of ammonia and saphos phosphate and the organic sources fish guano, bone meal and cattle manure. Except for the first two years of the experiment, all the fertilizer treatments were consistently and signi ficantly superior to the control. However, there was no significant difference between the effects of the inorganic and organic fertilizer mixtures on yield (Kg copra per hectare). INTRODUCTION The fertilizer field experiment conducted by the Tea Research Institute (Sri Lanka) to assess the performance of 3 kinds of nitrogenous fertilizers demonstrated that there was no difference in effect between organic and inorganic sources of nitrogenous fertilizer (Eden, 1937). The 3x3x3 NPK fertilizer experiment at Bandirippuwa on coconut in which nitrogen was supplied as sulphate of ammonia, calcium cyanamide and groundnut cake too showed that all three forms were equally effective (Salgado, 1946). Despite these experiences and the pheno menal increases in yield, recorded all over the world by the use of inorganic fertilizers, the clamour for the use of organic fertilizers persist. In response to this clamour, the Coconut Research Institute conducted a field experiment with coconut wherein, organic and inorganic sources of nitrogen and phosphorus were compared, along with two frequencies of application. This paper is confined to the comparison of organic and inorganic sources of nitrogenous and phosphatic fertilizers. Materials and Methods The experiment was laid out at Marandawila Estate, Bingiriya, on a loamy sand soil in the Intermediate Zone (rainfall). The chemical and physical characteristics of the soil are given in Table 1. The treatments consisted of (i) control, (ii) inorganic mixture applied annually, (iii) inorganic mixture applied biennially (iv) organic mixture applied annually, (v) organic mixture applied biennially, and (vi) cattle manure and supplements applied biennially. The experi mental layout was randomized design consisting of 6 blocks of 6 plots each. Each plot con tained 18 palms. The different plots were separated by guard rows of palms.


Lines of Sight sounds a call for radical perspectivalism. It calls for getting to the root of perspective and aims for a transfiguration of the values associated with a regime initially articulated by René Descartes in the registers of one-point perspective, coordinate geometry, and rationalist dualism. It may seem odd to make so much fuss about a mode or system dating from the seventeenth century. After all, subsequent developments in science and mathematics may be said to have surpassed Cartesian geometry and perspective, or at least to have shown their restrictions and limitations. The Cartesian paradigm may thus appear outdated today, easily relegated to a transitional role within classical or early modern sciences, or to the status of a precursor, an incomplete articulation outstripped by modern and contemporary forms of knowledge. But Lines of Sight is not first and foremost concerned with the bare materiality or scientific accuracy of Cartesian geometry or one-point perspective. Rather it is concerned with Cartesianism. As Martin Jay reminds us in the context of visual culture, Cartesianism is not simply a structurally determined outcome of the use of one-point perspective or coordinate geometry. It is the combination of this mathematical mode with "Cartesian ideas of subjective rationality in philosophy" that served to make Cartesianism appear to be "the dominant, and even totally hegemonic, visual model of the modern era." 1 In other words, Cartesianism is a historically articulated mode of rationalism, implying a highly specific field of rationality. Central to Cartesian rationality thomas lamarre Introduction


Two campaigns were conducted in October and November 2001 with the support of ESA to check the validity of existing emissivity models in L-band and to assess the accuracy which can be expected for sea surface salinity retrieved from the Soil Moisture and Ocean Salinity (SMOS) satellite measurements. Taking into account the influence of the various fetch conditions encountered during these campaigns, we study the influence of the sea state on emissivity. We use sea state measurements to estimate the wave age. Then we use a sea wave spectrum, which is wave age dependent, to compute brightness temperatures (Tb) with a two-scale emissivity model. We compare the simulated Tb with measurements and determine the validity of the sea state parameterization.


Private Stream Search allows users to perform keyword-based queries to a database without revealing any information about the keywords they are searching. Using homomorphic encryption, Ostrovsky and Skeith proposed a computationally secure solution to this problem in 2005. However, their solution requires the server to send an answer of size O(mS log m) bits when m documents of S bits match the query, while a non-private query only requires mS bits. In this work we propose two new communication optimal constructions, both allowing a communication expansion factor (compared to a non-private query) asymptotically equal to 1 when m and S increase. More precisely, our first scheme requires m(S + O(log t)) bits (where t is the size of the database) and our second scheme m(S +C) where C is a constant depending on the chosen computational security level.


This paper addresses the representation of female rebellion and madness in the Kuwaiti musalsal ʿIla al-dunya al-salam which was produced in 1987. The show revolves around two sisters, Mahthootha and Mabrooka, adult women who are residents of a mental institution. The law dictates that their uncle is their guardian and has complete control of their finances. He devises a plan to strip them of their rights and their inheritance by committing them to the psychiatric institution. At the hospital, the audience meets many women with similar fates. The stereotypes of madness present it as dangerous and as affecting more women than men. Male domination features as a recurrent theme throughout, as all the male characters abuse their power, whether in the form of familial or medical authority. The dichotomy of sane/insane is reversed as the characters outside the hospital are cruel, corrupt and yet empowered due to social factors, gender and class. The series raises important questions and considers patriarchal oppression and Kuwaiti women's experience in both the private and public spheres.

In estimation theory, the asymptotic (in the number of samples) efficiency of the Maximum Likelihood (ML) estimator is a well known result [1]. Nevertheless, in some scenarios, the number of snapshots may be small. We recently investigated the asymptotic behavior of the Stochastic ML (SML) estimator at high Signal to Noise Ratio (SNR) and finite number of samples [2] in the array processing framework: we proved the non-Gaussiannity of the SML estimator and we obtained the analytical expression of the variance for the single source case. In this paper, we generalize these results to multiple sources, and we obtain variance expressions which demonstrate the non-efficiency of SML estimates.


The formulation and formation of emulsions imply a very large number of variables; hence, attaining the sought properties is usually long and tedious because of the large number of experiments to be carried out. The current state-of-the-art of physicochemical formulation may be thoroughly used to considerably reduce the number of required experiments and to indicate to the formulator the relation between the kind of properties to expect and the generalized formulation expression. After these first-order formulation factors are dealt with, several second-order factors are shown to be available to adjust the emulsion properties upward or downward in order to satisfy the specifications, either directly or by means of a multistep process. can change considerably) and in a lesser measure on the oil and aqueous phase nature, and other variable such as temperature. The characteristics of the components, particularly, the surfactant, have been represented by various parameters introduced over the years. About 50 years ago, the hydrophilic–lipophilic balance (HLB) number was introduced as an empirical estimation of the dual tendency of the surfactant, essentially related to the proportions of its hydrophilic and lipophilic parts and, to some extent, to the oil type. This approach is rather inaccurate, but it is extremely simple and is still useful as a first approximation and to compare similar cases. However, it may be completely erroneous in some instances like comparing cases with different surfactant or oil families. Davies' intent to separate the HLB number into group contributions made it easier to use in practice, but it did not really improve the accuracy, which is sometimes worse than ±2 units. Winsor's R ratio approach is based on the interactions of the surfactant molecule adsorbed at interface with neighboring oil and water molecules (labeled Aco and Acw, respectively, in Fig. 1). It allows to carry out some qualitative reasoning and to relate the R ratio of interactions at interface with the phase behavior at equilibrium as indicated in Fig. 1. There are only four different cases, hence much less than the number of actual variables in practice. R<1 and R>1 correspond to the so-called Winsor I and Winsor II biphasic systems, respectively, which exhibit an aqueous and an oil phase microemulsion in equilibrium with an excess oil and aqueous phase, respectively. R=1 is associated with the three-phase behavior so-called INTRODUCTION Emulsions are systems in which two immiscible liquids (referred to as oil and water) are temporarily mixed in some homogeneous way at some microscale to macroscale to produce the dispersion of one phase in the other. In general, it is called an emulsion only if the coalescence of the drops is inhibited during some time by some process involving surfactants or particles. This entry only deals with surfactant-stabilized emulsions. The emulsion desirable properties (type, drop size, and distribution, rheology, and persistence, often called stability) depend on the application. In most cases, the formulator challenge is to attain the sought-after product through 1) selecting the right substances (surfactant, oil, aqueous phase) and their right proportions, then 2) mixing them and making an emulsion through a process which could be quite complex. The optimization of the formulation and emulsification procedure may be made relatively simpler if the different aspects are segregated and treated separately, as shown in the following. FORMULATION CONCEPTS APPLIED TO EMULSIONS Early Concepts: HLB, PIT, Winsor's R A surfactant has a dual affinity for the aqueous (polar) and oil (nonpolar) phases, and the emulsion properties depend on that, i.e., strongly on the surfactant nature (because it 120045970 1 Manila Typesetting Company 11/06/2010 05:10AM Ab so rb an ce –


In our study adsorption of Hg +2 ions from water solutions on Sepiolite (Sep) and Modified Sepiolite (MSep) with cationic surfactants namely cetyl trimethyl ammonium bromide CTAB was investigated. Different parameters were used to investigate such as contact time, pH and adsorbent dosage. The adsorption capacity of MSep and Sep was examined. Both particles were characterized with FTIR spectrum. According to the our results the equilibrium adsorption data corresponded to the Langmuir isotherm and q max was 54,7 mg/g and 104,1 mg/g for Sep and MSep respectively. Kinetic parameters showed that pseudo-second-order adsorption kinetic model was the best model than the pseudo-first-order. MSep is more active adsorbent than Sep and it can be the best alternative adsorbent for removing of heavy metal from industrial waste water. In addition MSep can be used as adsorbent for removal of nonpolar toxic organic molecules, because sepiolite surface can be converted from hydrophilic form to hydrophobic form by CTAB resulting in increased the adsorption capacity.

Abstract This paper deals with surface defect detection. The approach investigated here attempts todetect grey level as well as texture defects. The defects are regarded as being characterizedby abrupt, local and unpredictable changes in an image. On the other hand, a defect-free surface is assumed to be regular and homogeneous, possibly with smooth and slow variation in its features. The detection is based on adaptive image modeling. It is shown that a classical autoregressive model is not really suitable for this detection problem. Then, two modifiedmodels are proposed. Their advantage lies in their taking into account the grey level value as well as the texture information.The model adaptation can be stated as a joint cxptimization problem with constraint. Two different algorithms are defined and tested. The first algorithm performs the adaptation in a recursive way while enforcing the constraint at each step, whereas the second one imposes the constraint only at optimum. The performance of each algorithms is assessed with a statistical test using syntheticimages. Finally, it is shown how this adaptive modeling technique can be applied to

The automatic panel turnover machine has the advantages of high turnover speed, safeand simple operation, and can prevent panels from being scored.


Evaluation of Ultrasound and Other Sources of Information to Predict Beef Carcass Traits and Final Carcass Value. (May 2006) Dustin Tyler Dean, B.S., Texas Tech University; M.S., Texas Tech University Chair of Advisory Committee: Dr. Andy Herring Purebred Beefmaster steers (n = 160) from five owners were fed at a commercial feedlot in South Texas beginning in November of 2004; 68 steers possessed pedigree information. Beginning in mid-November, steers were individually weighed and evaluated for ultrasound body composition at 56-d intervals by a certified technician. Feeder calf frame (FRM) and muscle (MUS) scores were assigned at initial ultrasound evaluation. Steers were fed and marketed through a lean-based, branded beef program and were harvested in two groups in May and June of 2005 at a commercial beef plant. Analyses were conducted to investigate the ability to predict carcass traits from the different sources of information available on these cattle. Evaluation of carcass traits were investigated using four sets of independent variables referred to as sources A, B, C, or D and ultrasound scan session (1 – 4). An analysis included initial weight at first scan session (IWT), FRM and MUS as independent variables through GLM procedures. B analyses utilized ultrasound measures of the longissimus area, intramuscular fat, fat thickness, rump fat, and gluteus medius depth along with IWT as independent variables. Multiple regression was performed on each carcass trait using IWT and ultrasound traits at each scan session. Mallow's CP was used to select a model that best described each


Principal Components Analysis (PCA)and Linear Discriminant Analysis (LDA)are two popular feature extraction methods for pattern recognition,and in image recognition,researchers usually use PCA+LDA instead of LDA.An enhanced linear discriminant analysis (ELDA)criterion,which integrates their merits,is proposed in the paper.It can not only overcome the PCA's shortcomings of lower precision when using the minimal distance,but also resolve the problem of projective vector solution of LDA when the within-class scatter matrix is singular.So the two-step method of PCA+LDA can be substituted by ELDA.Moreover,its recognition rate exceeds the single PCA,LDA,or PCA+LDA largely.Many experiments on ORL,YALE and NUST603 face database indicate that our method is effective.


Japan's postwar contribution to international political affairs is often described as limited, primarily due to Japan's focus on reconstructing and expanding its economy. However, this article argues that since the 1970s, Japan has played an active role in shaping the post-Vietnam War order in Southeast Asia. The Japanese actively sought to address the regional power vacuum that had been left by the diminished American presence and the Sino-Soviet attempts to fill it. To do so, in 1977, Japanese Prime Minister Fukuda Takeo announced a foreign policy initiative, the so-called Fukuda Doctrine. One of its pillars was Japan's commitment to promoting coexistence and cooperation among ASEAN nations and their communist Indochinese neighbors. Based on declassified documents and other primary sources, this study demonstrates the strategic nature of the Fukuda Doctrine and sheds light on its political, geopolitical, and security objectives. This includes the realization of a Southeast Asian order in which Japan could maintain a position of influence and, through it, enhance its international political role. The strategic implications of this approach explain why Japan continued to pursue the doctrine despite increased regional and global tension following the 1979 outbreak of the Cambodian conflict and renewed Cold War tensions in the early 1980s.


The audible noise which is produced by corona discharge from transmission line conductors is composed of two major components, namely "hum noise" and "random noise". Hum noise has a frequency of twice the power line frequency and is generated primarily in rain, fog, and highly humid environments. It is one of the major factors affecting conductor design of transmission lines for voltages above 500 kV and it is very important to predict level of hum noise near transmission lines. In this paper, through comparison between measured values in the UHV Akagi test line and that using corona cage, an experimental prediction method of hum noise in rain condition is proposed.


This study demonstrates the possibility of using an absorption chiller to produce chilled water for air conditioning, and at the same time recover the rejected heat producing domestic hot water. The absorption chiller considered for this application has been sized to suit a standard household and uses a solution of ammonia and water running on hot water at a temperature ranging from 80 - 120°C produced by thermal solar panels. The system consists of five main components: generator, rectifier, condenser, evaporator and absorber, and is divided in two sections at two different pressures. The section at higher pressure includes the generator, rectifier and condenser whereas the section at lower pressure includes the evaporator and the absorber. Heat in this type of system is usually rejected to the environment from the condenser, rectifier and absorber through a cooling tower or air cooler exchanger. In this paper we describe how to recover this heat to create domestic hot water by providing a quantitative evaluation of the amount of energy recovered by the proposed system, if used in the Australian region.


Although the relationship between personality traits and sexual self‐efficacy has received theoretical and empirical support, there is little information on how personality affects the sexual self‐efficacy of diabetic women. This study aimed to investigate the mediating role of marital satisfaction and sexual function in the relationship between personality traits and sexual self‐efficacy in diabetic women.


Abstract Strain performance as affected by cage or floor environments was analyzed within each of three 400-day laying periods. Each of 12 strains was replicated four times in each environment. Caged layers were housed at a rate of two birds per cage (25.4 cm. × 45.7 cm.). Floor densities ranged from 2675 cm.2 per bird to 1914 cm.2 depending upon trial year. Strains studied were not consistent among trials; therefore, each laying period was reviewed separately. Mortality, hen-day production, feed efficiency, egg weight, feed consumption and Haugh unit score were the evaluation criteria. Considerable strain difference was noted regardless of the criteria. In general, floor birds had better livability, higher hen-day production and a slightly higher feed intake. Caged birds laid larger eggs and utilized feed more efficiently. When within strain performance of caged birds was compared with that of sisters on the floor, positive and significant or highly significant coefficients were obtained with all criteria except percent mortality. Mortality correlation coefficients were positive but not statistically significant. Interaction of strain versus environment generally was non-significant regardless of criteria used, thus indicating that, within limitation, performance of a strain within a given environment can be predicted by its performance under other environments.


This study deals with the optimization problem of a dynamic vibration absorber (DVA) for multi-degree-of-freedom systems subjected to random input with a dominant frequency. A new design method, which optimizes the parameter of DVA composed of such passive elements as a spring and a damper, is proposed. In this method, a suboptimization method based on the optimal control theory is applied for the optimization problem with control structure constraints due to passive elements. This method can consider the input information and the constraints on the stroke of DVAs. The vibration control performance of this method is investigated and is compared with the previous method, in numerical calculations. As a result, the usefulness of the present method is verified.

Good human relationship is a very important factor to the health and development of college students, and also a powerful pledge to the construction of harmonious campus, especially to the students of independent colleges who are facing the fierce competition and the increasing social and psychological pressures. Compared with the students of other colleges, they have their own characteristics and peculiarities when communicating with others. It is of necessity to make a careful analysis of these peculiarities in their communication, apply the thoughts of Benevolence of Confucianism (Respectfulness, Kindness, Faith, Keenness and Benefit), and put forward some specific strategies of adjustment.

The aim of the paper is to present the findings of our own questionnaire-based quantitative study carried out in 2018. The research questionnaire was sent to companies in the databases of two universities (the database of enterprises cooperating with each university), which were selected according to the criterion of the number of employees (micro, small, medium, and large companies). The study attempted to identify the correlations among the following variables: people-oriented management, non-people-oriented management, direct active and passive participation, and engagement in work. Two research questions drove the research process: (RQ1) What are the links between people-oriented management and non-people-oriented management, direct (active and passive) participation, and work engagement? (RQ2) Does direct participation (active and passive) mediate the relationship between people and non-people-oriented management and employees' engagement? To this end, 1037 employees of companies operating in Poland reported the intensity of people-oriented management, non-people-oriented management, and direct (active and passive) participation. Research findings revealed that people-oriented management and active participation (i.e., co-deciding) are the most significant for work engagement. Not only does non-people-oriented management entail a low level of engagement but a lower level of direct participation as well. As far as the dimensions of engagement are concerned (i.e., vigour, dedication, and absorption), if one of them is more intense, the other are intense as well. People-oriented management translates into active participation and the latter into engagement in all the three dimensions. A structural equation model demonstrated that perceived people-oriented management and active participation were strong, positive, and significant predictors of work engagement.

3063 Background: Next generation sequencing (NGS) assays have accelerated the identification of mutations and potential matched targeted therapies for patients with cancer. However, a significant proportion of patients do not derive clinical benefit from targeted panel sequencing approaches. Cancer whole genome and transcriptome sequencing (cWGTS) offers the opportunity to fully characterize tumors, but are challenged by significant cost and computational resource requirements, concerns of assay sensitivity, and the need to deliver curated results within clinically relevant time frames. We performed a prospective study to evaluate the feasibility and utility of cWGTS in pediatric and young adults with solid tumors. Methods: We developed an automated analytical workflow (Isabl) for the QC and processing of cWGTS data to include ensembl variant calling for germline and somatic substitutions, indels, and structural variants; fusion genes; gene expression; and mutation signatures. Treatment biomarkers were annotated using OncoKB with generation of a clinical prototype report. We tested the feasibility of cWGTS implementation, evaluated its analytical validity compared to standard diagnostic assays, and characterized the clinical utility of incremental findings in a prospective study of children and young adults treated at Memorial Sloan Kettering Cancer Center. Results: A total of 114 patients were enrolled. Standard NGS assays (MSK-IMPACT, MSK-Fusion) identified clinically relevant biomarkers in 22% of cases. The cWGTS process was completed, from sample acquisition to summary report, in less than 12 days. Comparison against clinically reported NGS results demonstrated high precision and recall for reported mutations (98.8%) with high concordance across variant allele representations (r2> 0.73). cWGTS identified additional oncogenic mutations not captured by targeted sequencing in 49% of patients. Furthermore, incremental findings, beyond those identified by NGS assays, of direct clinical relevance (diagnostic, prognostic, therapy guiding) were identified in 26% of patients. Importantly, < 5% of the incremental findings would have been captured by whole exome or transcriptome sequencing alone. Of possible therapeutic relevance, cWGTS analyses revealed a significantly higher tumor mutation burden than previously reported (range: 0 - 11.23). Conclusions: We demonstrate feasibility, analytical validity and clinical utility of cWGTS approaches in pediatric and young adult cancer patients, with nearly half of all patients having incremental findings that were not captured by standard targeted NGS approaches.


ABSTRACT The different forms of epilepsy require different treatment, and drug choice depends on certain pharmacological and pharmacokinetic principles. Optimal treatment is based on single drug therapy, if possible, and monitoring of plasma antiepileptic drug levels. Such treatment, together with clinical observations and the cooperation of a well‐informed patient, will achieve the best seizure control. Nevertheless, seizure recurrence or increased seizure frequency is a possibility. When withdrawal of treatment is indicated, it must be done according to certain principles.

Ships and most offshore structures are commonly launched into water from dry docks. But, sometimes due to practical and economical restrictions, launching of some offshore structures takes place at floating launching platforms, usually barges. The latter type of launching is quite "usual" for jacket rigs. To assess the success of the launch operation usually numerical simulations are enough and model tests are usually not required. However, more recently, as part of the construction project of the new Brazilian jack-up oil platforms, an innovative launching operation was required: launching a jack-up using a jacket launching barge. The marked differences between the two types of structures involve hydrodynamic and structural complexities. From the hydrodynamical point of view, due to its greater volume compared to jackets, the jack-up may be subjected to greater loads as enters in water during launching, and then suffers great motions that may affect the barge motions and these, affect back, the jack-up motions. From the structural point of view, the heavier jack-up structure may cause greater stresses on the barge deck and rocker arms that should be properly addressed in order to determine the necessity for reinforcements in the jack-up and/or the barge. To assess the feasibility of this innovative launching operation, model tests were required to measure the motions of the barge and the jack-up and to evaluate the loads on the rocker arms. The present paper describes the experimental approach developed for simulating this unique launching operation. The calibration procedures are outlined and the main results of the systematic set of tests carried out are presented. Furthermore, the influence of some launching parameters such as friction coefficient, position of the center of gravity of the jack-up and initial launching angle are discussed.Copyright © 2013 by ASME


We study sensitivity of low-energy experiments to the scale of supersymmetry breaking √ F in models with light sgoldstinos — superpartners of goldstino. The limits on √ F may be obtained from direct and indirect measurements of sgoldstino coupling to photons, leptons, mesons and nucleons. There are three sources of constraints: (i) astrophysics and cosmology; (ii) precision laboratory experiments at low energies; (iii) rare decays. We discuss only processes with real sgoldstinos. For sgoldstino lighter than a few MeV and superpartner masses of the order of electroweak scale, astrophysical and reactor bounds on √ F are significantly stronger than limits which may be reached at future colliders. In models with heavier sgoldstino (up to 5 GeV), constraints from flavor conserving decays of mesons are complementary to ones coming from collider experiments. The most sensitive probes of sgoldstinos are flavor violating processes, provided that flavor is violated in squark and/or slepton sector. It is shown that sgoldstino contributions into FCNC and lepton flavor violation are strong enough to probe the supersymmetry breaking scale up to √ F ∼ 10 GeV, if off-diagonal entries in squark (slepton) mass matrices are close to the current limits in MSSM.

Classrooms tend to be absolute spaces, places where fluidity is rejected and nearly everything—from people, to ideas, to practices and policies—is viewed and organized through binary logic. Because binary logic is implicitly accepted as the natural order in schools and the structures resulting from it are highly unmalleable, individuals who differ from the norm are expected to assimilate and adapt so as not to disrupt the structure. Those who are too different from the norm to fit in or who refuse to accept the binary structure are viewed as problems and are often ostracized or blamed for disturbing the system. Even when evidence to dispute the binary logic emerges, such evidence is often ignored or rejected in favor of maintaining the status quo. As such, the need for educators with a social justice orientation is needed. The purpose of this qualitative study was to understand the process one teacher used to create inclusive spaces for students who identify with differences in order to develop a more critical understanding of the work of social justice teachers. The findings suggest the teacher enacted behaviors and maintained beliefs that contradicted her espoused social justice orientation and her classroom was at once both inclusive and exclusive. The findings illustrate the complexities inherent within the work of equity-oriented educators. Implications for educator preparation is discussed.


Sympathetic cooling is a method used to lower the kinetic energy of ions with complicated energy-level structures, via Coulomb interactions with laser-cooled ions in an ion trap. The ion to be sympathetically cooled is sometimes prepared outside of the trap, and it is critical to introduce this ion into the trap by temporarily lowering the potential of one endcap without allowing the coolant ion to escape. We study the time required for a laser-cooled ion to escape from a linear Paul trap when the voltage of one endcap is lowered. The escape time is on the order of a few microseconds, and varies significantly when the low-level voltage changes. A re-cooling time of a maximum of 13 s was measured, which can be reduced to approximately one hundred of milliseconds by decreasing the duration of the low-level voltage. The measurement of these critical values lays the foundation for the smooth injection and cooling of the ion to be sympathetically cooled.

Dark matter haloes are formed through hierarchical mergers of smaller haloes in large-scale cosmic environments, and thus anisotropic subhalo accretion through cosmic filaments has some impacts on halo structures. Recent studies using cosmological simulations have shown that the orientations of haloes correlate with the direction of cosmic filaments, and these correlations significantly depend on the halo mass. Using high-resolution cosmological N-body simulations, we quantified the strength of filamentary subhalo accretion for galaxy- and group-sized host haloes (Mhost = 5 × 1011–13 M⊙) by regarding the entry points of subhaloes as filaments and present statistical studies on how the shape and orientation of host haloes at redshift zero correlate with the strength of filamentary subhalo accretion. We confirm previous studies that found the host halo mass dependence of the alignment between orientations of haloes and filaments. We also show that, for the first time, the shape and orientation of haloes weakly correlate with the strength of filamentary subhalo accretion even if the host halo masses are the same. Minor-to-major axial ratios of haloes tend to decrease as their filamentary accretion gets stronger. Haloes with highly anisotropic accretion become more spherical or oblate, while haloes with isotropic accretion become more prolate or triaxial. For haloes with strong filamentary accretion, their major axes are preferentially aligned with the filaments, while their angular momentum vectors tend to be slightly more misaligned.

To improve efficiency and effectiveness, veterinary practitioners must match their marketing/advertising mix to the needs of their clients. We present an empirical approach to understanding what a client wants and the nature of mind-set segments, using different messages to convey the nature of a vet practice. Data suggest that pet owners divide into three distinct mindset segments: (a) responds strongly to elements that convey warmth and reassurance, (b) responds strongly to technology, and (c) responds to treatment that is similar in nature to that given to people. Each segment, both new and old clients, will respond when veterinarians use different ad messaging.


Introduction Cesarean section affects the process of colonization by bacteria transferred from the mother's skin and hospital bacteria, which in turn contributes to development of allergic conditions. Aim To assess selected risk factors, including the mode of delivery, parity, and the role of genetic factors for the development of allergic rhinitis and bronchial asthma. Material and methods The study was conducted in 18,617 respondents aged 6–7, 13–14, and 20–44 years who completed the ECRHS II and ISSAC questionnaires. Thirty percent of the study population underwent complementary assessments in the form of skin-prick tests, serum IgE levels, lung function tests, and peak nasal inspiratory flow (PNIF). The study is a part of the Epidemiology of Allergic Disorders in Poland (ECAP) study conducted in 8 areas in Poland (Warsaw, Lublin, Bialystok, Gdansk, Poznan, Wroclaw, Katowice, Krakow, and two rural areas – Zamosc and Krasnystaw counties). Results Respondents diagnosed with allergic rhinitis were at a significantly higher risk of inheriting the allergic condition if their mother (OR = 2.17; 95% CI: 1.98–2.39, p = 2.00 × 10–16) or father (OR = 2.20; 95% CI: 1.96–2.47; p = 2.00 × 10–16) suffers from this allergy. Conversely, in the group diagnosed with bronchial asthma, the highest risk of an inherited allergy was observed in situations where maternal (OR = 2.00; 95% CI: 1.57–2.55; p = 1.69 × 10–5) or paternal (OR = 1.94; 95% CI: 1.42–2.66; p = 3.61 × 10–5) grandparent was affected. Moreover, the risk of developing allergic rhinitis depended on the mode of delivery: i.e. it was higher for a Cesarean section (OR = 1.20; 95% CI: 1.01–1.43; p = 0.04) than vaginal delivery (OR = 0.88; 95% CI: 0.78–0.99; p = 0.03). The higher the number of siblings, the lower the risk of allergic rhinitis. Conclusions Allergy risk factors, especially those predisposing to allergic rhinitis, include not only genetic factors but also the mode of delivery: vaginal delivery or Cesarean section.

One of the main goals of information architecture is to organize an informational domain into a usable taxonomy. This is, however, a difficult task: final users can classify the same domain differently from experts, differences can arise between different groups of users, and the same users can create different taxonomies for different goals (goal derived taxonomies). Even using a participatory design – employing the card sorting technique – the resulting classification would be a sort of compromise, with some categories and items having a good consensus among users, and others being more problematic. The aim of this paper is twofold. The first purpose is to propose some measure of the fitness of a taxonomy as a both whole and as individual items. Three measures will be presented: a) the consensus analysis; b) an index adapted from Tullis and Wood (2004), here called auto-correlation and c) a new measure, called category validity, conceptually similar to the cue validity introduced by Rosch and Mervis (1975). All of these measures can be calculated from the results of the card sorting. The second goal is to present a contextual navigation that could ameliorate the findability of those items whose classification has been proven to be problematic, and to increase the information scent of the whole domain. An example will illustrate the use of the category validity and the implementation of the contextual navigation.


In Cananea, Sonora (northwestern Mexico), occurred a spilling of 40 000 m³ of an acid solution coming from the Buenavista del Cobre mine, which reached some tributaries and the main water stream of the Sonora River basin. This study aims to evaluate magnetic properties as proxies to assess residual pollution in soils and sediments affected by this kind of events. Particularly, the study focused on the temperature dependence of magnetic susceptibility. Measurements of volume magnetic susceptibility vs temperatures were performed, heating samples to 700 oC and cooling them back to room temperature. A strong increase (from three to six times the initial value) of magnetic susceptibility during heating was observed on precipitates of the acid solution dam, and on affected soils and sediments, starting at ~330 oC, and reaching a maximum at ~430 oC. An even stronger increase was observed during cooling. These increases are due to the transformation of iron bearing minerals (as jarosite, goethite and ferrihydrite) to ferrimagnetic iron oxides (as magnetite). Samples of non-affected soils and sediments did not exhibit this increase during heating, but a decrease at ~550 oC related to (titano)magnetite Curie temperature, and they presented lower κ values during cooling. The transformation of these iron-bearing minerals (commonly occurring in mine wastes and acid drainage) marked by a strong κ increase during heating, can be used as an indicator of the presence of residual pollution.


Since the beginning of the 21st century, the modern society has witnessed an increased mobility as a vector for new lifestyles of the "civilization of mobility". Tied with the impressive developments in the information and communication technologies, the concept of mobility continues to be a significant challenge that needs to be considered while planning the city or studying the society. Comparing the contemporary society to the past nomadic communities appears as an approach that would explore and decrypt some socio-spatial phenomena where rapid transformations would be otherwise difficult to analyze using non-comparative methodologies. This article attempts to revisit some similarities between the contemporary society and the nomadic society in relation to the issue of mobility. The similarities are then analyzed with regard to two key concepts which shape the social pattern on the territories: the spatial reference and the nature of social links. The article ends with an exploration of proposals on how to take into account the contemporary mobility, henceforth smart, at the level of urban planning policies.


This paper treats the problem of detection of data hazards in superscalar execution. The algorithms of independent instruction detection are represented. They can be used in out-of-order execution logic and a code optimized algorithm. The algorithms use the platform of Intel Pentium architecture and analyze the IA-32 instruction set. The implementation of the algorithms is in a software simulator, which represents the way the Intel Pentium Processor works. It can be used in software module, which simulate out-of-order execution logic.
