Testes diagnósticos baseados na detecção de ácidos nucleicos sem amplificação prévia através da utilização de nanopartículas de ouro (AuNPs) têm sido descritos para várias enfermidades. Este trabalho teve como objetivo desenvolver uma técnica de AuNPs não modificada para detecção de Actinobacillus pleuropneumoniae (App). Utilizaram-se 70 amostras de pulmão de suínos, 17 sem lesão e 53 com lesões características de pneumonia, objetivando a detecção de App. O oligonucleotídeo utilizado foi baseado no gene ApxIV. O teste de AuNPs apresentou sensibilidade de 93,8% e especificidade de 84,6% quando comparado com a detecção pela PCR. Os resultados mostraram boa concordância entre os testes de AuNPs e a PCR, sendo que a técnica pode ser utilizada como alternativa aos testes convencionais, já que é de fácil e rápida execução e não exige infraestrutura e mão de obra especializada.

Published: August 2014

Staphylococcal enterotoxins are the leading cause of human food poisoning worldwide. Staphylococcus spp. are the main mastitis-causing agents in goats and frequently found in high counts in goat milk. This study aimed to investigate the occurrence of enterotoxin-encoding genes in Staphylococcus aureus associated with mastitis in lactating goats in Paraiba State, Brazil. Milk samples (n=2024) were collected from 393 farms. Staphylococcus aureus was isolated in 55 milk samples. Classical (sea, seb, sec, sed, see) and novel (seg, seh, sei) enterotoxin-encoding genes were investigated by means of polymerase chain reaction (PCR). From thirty-six tested isolates, enterotoxin-encoding genes were detected in 7 (19.5%) S. aureus. The gene encoding enterotoxin C (seC) was identified in six isolates, while seiwas observed in only one isolate. The genes sea, seb, sed, see, seg and seh were not observed amongst the S. aureus investigated in this study. In summary, S. aureus causing mastitis in goats can harbor enterotoxin-encoding genes and seC was the most frequent gene observed amongst the investigated isolates. This finding is important for surveillance purposes, since enterotoxin C should be investigated in human staphylococcal food poisoning outbreaks caused by consumption of goat milk and dairy products.

Published: August 2014

A dexametasona, um glicocorticóide sintético, tem a capacidade de atravessar a placenta aumentando o nível de circulação de corticosteróides da mãe para o feto durante a prenhez. Quando administrada nas fases finais da prenhez pode produzir efeitos indesejáveis na formação da placenta e em vários órgãos da prole. Assim, o presente estudo objetivou investigar o efeito da administração da dexametasona (0,8mg/dia/animal) nos cinco primeiros dias da prenhez, sobre o desenvolvimento placentário de ratas. Utilizou-se 30 ratas albinas, divididas em dois grupos: Grupo I -ratas prenhes sem aplicação de dexametasona, sacrificadas ao 7º e 14º dia; Grupo II -ratas submetidas à aplicação de dexametasona nos cinco primeiros dias de prenhez, sacrificadas ao 7º e 14º dia. Os resultados mostraram que a dexametasona não afetou o número e a histologia dos sítios de implantação, porém, promoveu alteração no disco placentário ocasionando hipertrofia na camada de células trofoblásticas gigantes. Não foram evidenciadas alterações no teor de colágeno, porém houve interferência no metabolismo do glicogênio no espongiotrofoblasto trofospongio. Na morfometria de linhas houve diferença entre os grupos na região de labirinto e células trofoblásticas gigantes, porém a morfometria de pontos só ratificou as alterações percebidas na região do labirinto.
O método psicanalítico aplicado à pesquisa social: a estrutura moebiana da alteridade na possessão
Authors: Godoy Daniela Bueno de Oliveira Américo de , Bairrão José Francisco Miguel Henriques
Published: August 2014

Tendo por finalidade explorar possibilidades de aplicação do método psicanalítico além da prática clínica, este trabalho propõe uma interpretação topológica lacaniana do fenômeno da possessão na umbanda. Visa-se apreender o sujeito para além do psiquismo individual, de forma que o espaço subjetivo compreenda - continuamente - a transição de identidades ocorrida no corpo do médium. Isso se sustenta pela concepção de que o sistema interpretativo (que organiza a relação entre o mundo dos espíritos e o mundo dos vivos) e o sujeito coexistem em uma mesma estrutura. Para tanto, parte-se do conceito de significante, por ele ser capaz de criar uma rede de sentidos em função do efeito de um dizer inconsciente. Mediante um estudo de caso, mostra-se como, na possessão, o sujeito - concomitantemente suposto agente e efeito da combinatória significante - apresenta-se tanto como médium quanto como espíritos possuidores, os quais constituem o avesso e o direito de uma estrutura unilateral.

Published: August 2014

Tendo em vista a consolidação do ECA, tivemos, na cidade de Vitória (ES), a implantação do Programa de Educação em Tempo Integral (PETI). Este visa o atendimento, no contraturno escolar, de crianças e adolescentes em "situação de risco" por meio de atividades extracurriculares. Como parte do PETI, o Projeto Brincarte atende alunos de 4 a 6 anos da Educação Infantil. Este artigo objetiva evidenciar as implicações decorrentes da classificação "de risco" para as famílias atendidas pelo Brincarte. Tratou-se de pesquisa intervenção, com a presença ativa da pesquisadora em diversas atividades do Projeto tais como reunião da equipe administrativa e reuniões de pais e com a utilização de diário de campo para registros de todos os acontecimentos do campo por um período de 3 anos. Delimitadas a partir de uma ideia de risco pernicioso, às famílias imputa-se uma subjetividade-risco, na qual estão relacionados todos os fatores "fora da ordem" ou dos modelos estabelecidos como "normais" na sociedade.
Avaliação da mudança nas relações interpessoais através do CCRT. Estudo de caso psicanalítico
Authors: Salgado Ana Isabel Manta , Pires António Augusto Pazo
Published: August 2014

O objetivo foi perceber a evolução das relações interpessoais de uma paciente ao longo da sua psicanálise com a duração de quatro anos. O método Core Conflictual Relationship Theme foi aplicado para identificar os episódios de desejos, respostas do outro e respostas do self. Foram analisadas as notas de sessões em sete momentos diferentes: no início, seis, 12, 18, 24, 30 e 36 meses. Através da análise do conflito central presente nos episódios relacionais observa-se uma evolução ao longo da psicanálise que pôde ser confirmada pelos dados clínicos. A paciente passa de desejos de se opor, magoar e controlar os outros, ser distante e evitar conflitos no início da terapia para o desejo de ser amada, compreendida e ajudar os outros no fim da terapia. Quanto às respostas dos outros a paciente vai alternando ao longo da análise entre senti-los como rejeitantes e que gostam dela. Quanto às respostas do self uma alternância entre sentimentos depressivos e autoaceitação.

Published: August 2014

Neste trabalho, apresenta-se a metodologia utilizada e os resultados da análise do comportamento de vigotas armadas e reforçadas externamente à flexão com manta de PRFC (polímeros reforçados com fibras de carbono). Avalia-se o comportamento do reforço de vigotas de concreto comum e compara-o com o do reforço de vigotas moldadas com um compósito cimentício à base de argamassa e fibras curtas de aço. O objetivo principal foi investigar a influência do compósito cimentício (escolhido sem maiores critérios) sobre o comportamento e o modo de ruína das vigotas reforçadas. Para tanto, uma série de ensaios de flexão em três pontos em seis vigotas foi conduzida, além dos ensaios de caracterização dos materiais: ensaios de flexão em três pontos em corpos-de-prova prismáticos entalhados, ensaios de tração em barras de aço e ensaios de compressão axial em corpos-de-prova cilíndricos. Adicionalmente, uma análise de elementos finitos foi desenvolvida com objetivo de comparar os resultados obtidos com os experimentais. O ganho de tenacidade e de resistência à fissuração provocou mudanças significativas no desempenho da vigota moldada com fibras e reforçada quando comparada com a vigota reforçada de concreto comum.
Comparativo das propriedades do concreto autoadensável (CAA) utilizando areia fina e cinza volante
Authors: Tutikian B. F. , Dal Molin D.
Published: August 2014

O objetivo deste artigo é contribuir para a tomada de decisão sobre a definição do uso de materiais finos responsáveis pela resistência à segregação do concreto auto-adensável (CAA). Neste estudo, amostras de CAA foram dosadas com cinza volante, um material pozolânico, e areia fina, que é um material não pozolânico, utilizando o método de dosagem proposto por Tutikian & Dal Molin (2007) [1]. Foi observado que a utilização de cinza volante aumentou a resistência à compressão, principalmente nas idades mais avançadas, assim como os valores de módulo de deformação e velocidade das ondas de ultrasom. Também diminuiu a penetração de íons cloretos, para os mesmos valores de resistência em comparação com os CAA com areia fina e o custo final dos CAA com cinza volante foi inferior. Foram apresentados tanto os diagramas de dosagem como os de desempenho.

Published: August 2014

O entendimento da influência de cada fase do concreto, dentre as quais merece destaque a pasta de cimento, é importante para o desenvolvimento de um concreto mais eficiente, com maior velocidade de hidratação e resistência à propagação de fissuras. O módulo de elasticidade do concreto é um dos principais parâmetros de projeto de estruturas e têm grande influência na velocidade do processo de construção e na durabilidade das estruturas. A capacidade de deformação do concreto depende das características intrínsecas dos produtos de hidratação do cimento, agregados, zona de transição e poros, além de variáveis inerentes ao processo, como velocidade de hidratação e condições climáticas. O objetivo deste estudo foi avaliar as propriedades mecânicas de módulo de elasticidade e resistência superficial (dureza) para uma pasta de cimento, através da técnica da nanoindentação instrumentada e, complementarmente, comparar este valor do módulo de elasticidade, utilizando o método normatizado para concreto. Os resultados obtidos pela nanoindentação foram de 17,2 GPa para o módulo de elasticidade e de 0,90 GPa para a dureza. A determinação do módulo de elasticidade tangente inicial calculado pela NBR 6118 1 foi de 9,6 GPa. A nanoindentação mostrou-se uma ferramenta válida para avaliar modificações nanoestruturais de pastas de cimento.
Estimation of compressive strength based on Pull-Out bond test results for on-site concrete quality control
Authors: Lorrain M. S. , Barbosa M. P. , Silva Fº L. C. P.
Published: August 2014

Quality control of structural concrete has been conducted for several decades based mainly on the results of axial compression tests. This kind of test, although widely used, is not exempt from errors and has some considerable drawbacks that may affect its reliability, such as the need for appropriate and careful specimen conditioning and adoption of adequate capping techniques. For these reasons, it would be useful to have complementary or alternative ways to check compressive strength, in order to improve concrete quality control. The use of a bond test to monitor concrete strength is being proposed by an international group of researchers from France, Tunisia and Brazil as a potential means to this end. Given the fact that the link between bond resistance and concrete strength is already well established, this type of test seems to be a viable alternative to traditional methods. Nonetheless, to check if the underlying principle is sound when used in different circumstances, the group has been gathering data from several studies conducted by different researchers in various countries, with distinct concretes and rebar types. An analysis of the data collected shows that there is a clear and strong correlation between bond resistance and compressive strength, no matter the influence of other variables. This result validates the basic idea of using an Appropriate Pull-Out (APULOT) bond test to assess concrete strength. If the general principle is valid for random data obtained from different studies, the definition of a clear and appropriate test will probably lead to the reduction of experimental noise and increase the precision of the strength estimates obtained using this method.

Published: August 2014

A construção de barragens de CCR prioriza a minimização de interferências, como a execução da face de montante, para garantia da produtividade. O estudo procurou avaliar as propriedades físicas do CCR enriquecido com calda, em substituição ao concreto convencional usualmente empregado na face, utilizando os mesmos materiais, central de concreto, mão de obra e equipamentos, empregados na construção da Usina Hidrelétrica Mauá. Para tanto foram feitos prismas experimentais de campo (com diferentes relações água/cimento e quantidades de calda) e posterior extração de testemunhos, os quais foram submetidos a ensaios mecânicos e de permeabilidade. Os resultados mostraram que para relações água/cimento 0,74, o material resultante atendeu às especificações de projeto, para consumos de cimento notadamente menores (entre 70 e 85% do CCV).

Escola como agência de civilização: projetos formativos e práticas pedagógicas para a educação rural no Brasil (1946-1964)
Authors: Andrade Flávio Anício
Published: August 2014

No presente estudo se propõe uma análise acerca da escola rural no Brasil, no contexto do projeto de expansão dos valores ligados ao espaço urbano e ao concomitante processo de industrialização que se aprofunda na segunda metade do século 20. Para os que pensavam as políticas educacionais do Estado brasileiro, a escola primária rural deveria tornar-se um centro de irradiação dos novos valores do industrialismo, ao incorporar e refletir ela mesma tais valores. O contexto histórico em que ocorre tal processo encontra-se marcado pela transformação do Estado em agente promotor de uma nova configuração econômica, política e social no Brasil, sendo o eixo de sua ação o esforço de expansão do setor industrial do país. Concluiu-se que o projeto de expansão e readequação da educação rural teve como objetivo a extensão dos hábitos, atitudes e formas de comportamento característicos de uma civilização industrial.
Lições de coisas e ensino das ciências na França no fim do século 19: contribuição a uma história da cultura
Authors: Kahn Pierre
Published: August 2014

Além das grandes reformas realizadas na organização institucional da escola primária, gratuidade, obrigação, laicidade, os republicanos franceses do final do século 19 quiseram operar uma profunda transformação dos conteúdos de ensino e das normas pedagógicas. As ciências experimentais foram imensamente beneficiadas com isso e se tornaram, em 1882, uma disciplina regular da escola primária com os seus programas e a sua carga horária. A lição de coisas, procedimento pedagógico pelo qual os reformadores se entusiasmaram desde 1860, ficará estreita e naturalmente associada a esse ensino. Ela é, inicialmente, de fato, uma lição de observação: onde os alunos encontrarão melhores oportunidades para observar do que nas aulas de história natural ou de física elementar? Assim, ligados entre si, o ensino das ciências e a lição de coisas têm dois aspectos, um prosaico, outro encantador. Contexto prosaico: o ensino das ciências, destinado a alunos que, na sua maioria, não conhecerão outra escola a não ser a primária, deve permanecer prático e usual. A lição de coisas convém especialmente a esse ensino porque ela trata primordialmente das realidades concretas e familiares. Contexto encantador: o ensino das ciências é um instrumento poderoso de educação intelectual, até mesmo de educação moral e política. Ele representa a esperança de uma educação liberal primária tão completa, digna e válida em seu gênero, quanto às humanidades clássicas do secundário. A lição de coisas, ao fazer corresponder a abordagem pedagógica ao próprio método da ciência, o método indutivo, se torna então, por excelência, o que permite esta educação intelectual. Esta tensão não é própria ao ensino das ciências. Essa análise enseja, antes de mais nada, evidenciar o duplo discurso que os republicanos tiveram sobre uma escola que eles transformaram, simultaneamente, em realidade e sonho.
Measuring accessible journeys: a tool to enable participation
Authors: Burdett Bridget
Published: August 2014

This study set out to demonstrate the feasibility and usefulness of a series of pedestrian counts, including counting the subset of pedestrians who use visibly identifiable mobility aids. The resulting proportion of mobility aid users can then be used as a proxy measure of relative accessibility for each count site. The study acknowledges the diversity of disability, and the count is not intended to capture all people who identify as having disability of any kind. It was estimated from Statistics New Zealand data that approximately 3% of New Zealand's adult population uses a mobility aid for travel at any particular time. This figure includes those identifying as having permanent disability, as well as an estimate to account for those not included in this figure, namely children, people who do not identify as having a disability but nevertheless use a mobility aid, and those with temporary disability requiring use of a mobility aid. The study identified opportunities to use the tool to remove gaps in the delivery of accessible transportation, across all parts of its system from policy and planning, through design, construction and monitoring. Its widespread promotion will support more objective measurement of inclusion, to inform best-practice infrastructure investment for all.

This paper examines how a network of small/medium-sized enterprises was developed to enable reuse and resource conservation in the information and communications technology sector by exchange of used equipment over a resource exchange internet platform. The network's effectiveness and potential for expansion is also examined. The results demonstrate that it is possible and in many cases economically viable to increase the reuse stream of equipment and to extend the network's activities to a European level. The expectation of doubling the amount of traded appliances within the network was greatly exceeded. The successful development of technical, legal and financial guidance led to its incorporation into an accredited industry guideline.
A comparison of traffic estimates of nocturnal flying animals using radar, thermal imaging, and acoustic recording
Authors: Horton Kyle G. , Shriver W. Gregory , Buler Jeffrey J.
Published: August 2014

There are several remote‐sensing tools readily available for the study of nocturnally flying animals (e.g., migrating birds), each possessing unique measurement biases. We used three tools (weather surveillance radar, thermal infrared camera, and acoustic recorder) to measure temporal and spatial patterns of nocturnal traffic estimates of flying animals during the spring and fall of 2011 and 2012 in Lewes, Delaware, USA. Our objective was to compare measures among different technologies to better understand their animal detection biases. For radar and thermal imaging, the greatest observed traffic rate tended to occur at, or shortly after, evening twilight, whereas for the acoustic recorder, peak bird flight‐calling activity was observed just prior to morning twilight. Comparing traffic rates during the night for all seasons, we found that mean nightly correlations between acoustics and the other two tools were weakly correlated (thermal infrared camera and acoustics, r = 0.004 ± 0.04 SE, n = 100 nights; radar and acoustics, r = 0.14 ± 0.04 SE, n = 101 nights), but highly variable on an individual nightly basis (range = −0.84 to 0.92, range = −0.73 to 0.94). The mean nightly correlations between traffic rates estimated by radar and by thermal infrared camera during the night were more strongly positively correlated (r = 0.39 ± 0.04 SE, n = 125 nights), but also were highly variable for individual nights (range = −0.76 to 0.98). Through comparison with radar data among numerous height intervals, we determined that flying animal height above the ground influenced thermal imaging positively and flight call detections negatively. Moreover, thermal imaging detections decreased with the presence of cloud cover and increased with mean ground flight speed of animals, whereas acoustic detections showed no relationship with cloud cover presence but did decrease with increased flight speed. We found sampling methods to be positively correlated when comparing mean nightly traffic rates across nights. The strength of these correlations generally increased throughout the night, peaking 2–3 hours before morning twilight. Given the convergence of measures by different tools at this time, we suggest that researchers consider sampling flight activity in the hours before morning twilight when differences due to detection biases among sampling tools appear to be minimized.
The Training, Value, and Reality of Master’s-Level Mental Health Counselors
Authors: Cardaciotto LeeAnn , Tonrey Donna A.
Published: August 2014

There is a need for individuals trained in professional practice that cannot be met by psychologists and psychiatrists. Because the American Psychological Association (APA) maintains that the minimum requirement for the independent practice of psychology is a doctorate degree, master’s-level programs significantly increased and produce graduates in professions separate from psychology. These master’s-level clinicians are more likely to identify professionally with the standards and values endorsed by counseling, marriage and family therapy, and social work organizations (McPherson, Pisecco, Elman, Crosbie-Burnett, & Sayger, 2000). Given the number of master’s-level clinicians working side by side with clinical psychologists, this article aims to provide a brief introduction of the master’s-level clinicians. Furthermore, it focuses on the counseling profession because it has the largest overlap with psychology. In the discussion, the authors highlight strengths of master’s-level training in counseling as well as identify areas that could be informed by the field of psychology. Similarly, this article discusses aspects of training that master’s-level counselors receive, which may inform the field of applied psychology, such as skill-training models and the credentialing of supervisors.
Noninvasive Quantification of Green Fluorescent Protein Labeled Escherichia coli in a Dynamic Capillary Fringe by Fluorescence Intensity
Authors: Jost Daniel , Winter Josef , Gallert Claudia
Published: August 2014

Quantification of bacteria attached to sand grains is usually not possible without destroying biofilms or the sand structure. In situ quantification of autofluorescing or of fluorescence‐carrying bacteria might be an alternative if fluorescence intensity (FI) was strong enough and could be related to cell numbers. For calibration, a Hele–Shaw cell was filled with sterile quartz sand and sectioned for inoculation with increasing cell densities of Escherichia coli strain HB101 K12 pGLO, overexpressing green fluorescent protein (GFP). Digital photographs of the single sections were taken under ultraviolet light at wavelength λ = 365 nm for fluorescence quantification by TotalLab Quant software. The FI was related to respective cell densities per quartz sand volume. Growth of GFP‐labeled E. coli, suspended in Lysogeny broth (LB) medium (dissolved organic C = 6.8 g L−1), could thus be quantified noninvasively in capillary fringe (CF) laboratory systems simulating static or hydrodynamic conditions. Best growth conditions existed in the transition zone of the CF, where after 3 d the highest cell densities of 5.0 to 6.5 × 108 cells cm−3 were determined. The E. coli cells that grew attached as a biofilm in the different sections of the CF could also be quantified under flow‐through conditions and after fluctuation of the water table. For reliable results, FI calibration must be performed in the same setup as used for experiments, and fluorescence characteristics of the bacterial strain should be well known. This noninvasive method using bright fluorescing bacteria can be advantageous for the determination of bacterial growth and biofilm formation in laboratory experiments with unsaturated soil under changing hydraulic conditions.

We examined the mediating role that job satisfaction plays in the relationship between emotional intelligence (EI) and perceived general health. Participants were 124 faculty members in the School of Basic Medical Sciences at Southern Medical University, China. The simple path and fully
mediated models were subjected to structural equation modeling. Results indicated that EI was positively correlated with job satisfaction, and that job satisfaction was positively correlated with perceived general health. However, when job satisfaction was controlled for, the partial correlation
between EI and perceived general health became nonsignificant. Finally, we found that job satisfaction mediated the relationship between EI and perceived general health.

in this study are discussed.
Approaching Opponents and Leaving Supporters: Adjusting Physical Proximity to Reduce Cognitive Dissonance
Authors: Vaidis David C. , Oberlé Dominique
Published: August 2014

In our study of cognitive dissonance 59 students adjusted their physical proximity with an opposing other to manage dissonance. Participants wrote a counterattitudinal essay (vs. proattitudinal), then each of them was told he/she had to discuss the topic with another student who was
against the current topic (vs. in favor of). While the experimenter allegedly fetched the other student the participant set up the room by installing 2 chairs. The distance between the 2 chairs was used to measure the proximity with the other. The results showed that in the dissonance condition
participants set greater physical proximity when the other disagreed with their initial attitude and less physical proximity when the other was supportive of their initial attitude. We suggest further research is conducted to confirm the use of proximity as a means of dissonance reduction.
Effects of Dispositional Coping Strategy and Level of Health Anxiety on Attentional Bias
Authors: Kim Sujin , Kim Kiho , Lee Jang-Han
Published: August 2014

We examined the influence of dispositional coping strategy and level of health anxiety (HA) on attentional bias in regard to health-related stimuli. In a dot-probe task participants were exposed to health and nonhealth-related words for 1,250 ms. The high HA group showed significantly
greater attentional bias in regard to health stimuli compared to the low HA group. In addition, in the low HA group there was no difference in attentional bias toward health-related words according to whether they were blunters (cognitively avoidant) or monitors (vigilant for information),
but in the group with high HA blunters showed stronger attentional bias for health stimuli compared to monitors. Our results in this study confirmed that not only did individuals with HA show a bias toward selective attention to health-related information, but also that this bias was affected
by their dispositional coping strategy.
Nonbelievers' Beliefs About Religion in China
Authors: Jing Xiaojuan
Published: August 2014

In China nonbelievers are showing an increasing interest in religion whereas believers in the rest of the world are being less influenced by religion. I investigated what nonbelievers know about religion within Chinese society. Data collection was via random sampling among university
students across 16 provinces in China. I evaluated data from 638 respondents about their self-reported beliefs using the religiosity subscale of the Social Axiom Survey. The results indicated that Chinese nonbelievers take a neutral stance as to the existence of a Supreme Being or the positive
consequences of having religious beliefs. The neutrality of nonbelievers' beliefs about religion may be affected by the coincidence of the development of religion and Chinese religious culture. The findings in this study will enrich understanding of nonbelievers' views regarding religion in
the Chinese culture and help to generate more, and more meaningful, dialogue between believers and nonbelievers.
Auditing Subsequent Events: Perspectives from the Field
Authors: Herda David N. , Lavelle James J.
Published: August 2014

A research synthesis team formed by the Auditing Section of the American Accounting Association recently authored a paper (Chung et al. 2013) addressing the audit of subsequent events (SEs). The audit of SEs is a difficult audit area, as approximately one-third of the Public Company Accounting Oversight Board's inspection reports and numerous Securities and Exchange Commission enforcement releases identify deficiencies in this area (Chung et al. 2013). Chung et al. (2013) developed a model and proposed a series of research questions encouraging future academic research in this area. In this paper, we address several of these questions by surveying 76 practicing auditors. We summarize the auditors' responses and present recommendations that may be useful in improving audits of SEs.

Published: August 2014

Objective—To compare long-term survival and quality of life data in dogs with clinical signs associated with a congenital portosystemic shunt (CPSS) that underwent medical or surgical treatment.

Design—Prospective cohort study.

Animals—124 client-owned dogs with CPSS.

Procedures—Dogs received medical or surgical treatment without regard to signalment, clinical signs, or clinicopathologic results. Survival data were analyzed with a Cox regression model. Quality of life information, obtained from owner questionnaires, included frequency of CPSS-associated clinical signs (from which a clinical score was derived), whether owners considered their dog normal, and (for surgically treated dogs) any ongoing medical treatment for CPSS. A Mann-Whitney U test was used to compare mean clinical score data between surgically and medically managed dogs during predetermined follow-up intervals.

Results—97 dogs underwent surgical treatment; 27 were managed medically. Median follow-up time for all dogs was 1,936 days. Forty-five dogs (24 medically managed and 21 surgically managed) died or were euthanized during the follow-up period. Survival rate was significantly improved in dogs that underwent surgical treatment (hazard ratio, 8.11; 95% CI, 4.20 to 15.66) than in those treated medically for CPSS. Neither age at diagnosis nor shunt type affected survival rate. Frequency of clinical signs was lower in surgically versus medically managed dogs for all follow-up intervals, with a significant difference between groups at 4 to 7 years after study entry.

Conclusions and Clinical Relevance—Surgical treatment of CPSS in dogs resulted in significantly improved survival rate and lower frequency of ongoing clinical signs, compared with medical management. Age at diagnosis did not affect survival rate and should not influence treatment choice.

Visegrad Cooperation is the regional organization of four states known as the Visegrad Group or the Visegrad Four (the Czech Republic, Poland, Hungary, and Slovakia). The purpose of cooperation is joint representation of economic, diplomatic and political interests of these Central and Eastern European countries and coordination of their possible measures. In the framework of this study, the major trends regarding the average area and farm number of agricultural holdings in the Visegrad Group are examined and evaluated. We attempted to elucidate structural differences between the farm structures of these countries, their different and unusual development and its reasons. Despite these differences, we have uncovered a number of identical trends and joint points as well. The average farm size in Slovakia and the Czech Republic was 28 or 135 hectares in 2007, while in 2010, this figure changed to 75 or 152 hectares in the circle of the observed agricultural holdings. For both countries, therefore, a significant increase in farm size was observed in the period under survey. While in Hungary the average size of 6 hectares in 2007 increased to 8 hectares in three years, then in Poland, the average farm was 12 or 10 hectares in size in the years under survey. In the circle of these countries, therefore, only a slight shift, mainly stagnation was observed, albeit on different bases: while the number of holdings under survey increased in Poland, it decreased in Hungary (similarly to Slovakia and the Czech Republic). Investigating the details regarding farm structure in these countries, it can be stated that most holdings carried out their activities on an area of under 20 hectares, in respect of distribution of agricultural land in the countries of the Visegrad Four. However, the survey results also revealed that in the vast majority of cases, the number of farms decreased, but there was an increase in their average size, that is, the process of concentration that has been experienced in the Western part of the European Union for the last two decades can be observed in these four countries as well.
Investigations into Load Spectra of UAVS Aircraft
Authors: Rodzewicz Miroslaw , Glowacki Dominik
Published: August 2014

The paper contains a description of a novel approach to the load spectra estimation applied to UAVs. The authors have developed a number of tools in the LabVIEW environment enabling an in-depth analysis of flight-log data. One major achievement was the separation of the load spectra induced by steering and the load spectra induced by turbulence. The authors have shown a significant influence of both of the main load sources on the fatigue life of the UAV airframe, calculated based on the P-M hypothesis. This approach to fatigue testing of composite UAV airframes needs to take into account the rate of load variations as these may affect the fatigue life of tested structures. The paper presents several schemes of calculation algorithms and a number of well-illustrated examples of the tests and investigations results.
Advanced Magnetic Materials for Aeronautics

Published: August 2014

In the field of magnetic sensors, magnetic microwires with positive magnetostriction are the materials of the future. Their mechanical and magnetic properties render them ideal materials for applications in aeronautics. A single microwire with a 40 jj.m diameter and a length of 10 mm is capable of capturing information about tensile stresses, magnetic fields, temperature and distance. This information is carried by a parameter called the Switching Field, HSW, which is specific for different types of microwire. Numerous physical qualities affect the HSW and through sensing of HSW, these qualities may be quantified. (A number of physical qualities affecting HSW can be sensed and quantified by means of a contactless induction method.) What distinguishes the system developed by the present authors from other measuring systems based on magnetic microwires is the positioning of a microwire outside the coil system. Thanks to this improvement it is possible to use microwires embedded directly in the construction material. Small dimensions microwires do not damage the structure of the construction material. The absence of a galvanic connection makes this technology even more interesting compared with traditional forge gauges. Offering the possibility of the simultaneous measuring of four parameters, this technology can be used in a wide range of aviation applications. Measurements of an external magnetic field can be usedfor the navigation and stabilization of an aerial vehicle. Tensile stress and distance measuring can be helpful to understand some processes occurring under the surface of the construction material and also to perform fatigue monitoring or structure load monitoring. Another big advantage of magnetic microwires is the low price. Just 1 gram of base material is sufficient to prepare about 40 km of microwire. All these features combine to offer us a material ideal for Smart Sensors, possibly available for use in the near future.
Construct Validation of a Small-Animal Thoracocentesis Simulator
Authors: Williamson Julie A.
Published: August 2014

Training students to perform emergency procedures is a critical but challenging component of veterinary education. Thoracocentesis is traditionally taught in the classroom, with students progressing to “see one, do one, teach one” during the clinical phase of their education. This method of teaching does not permit students to gain proficiency before performing thoracocentesis on a live animal in a high-stakes, high-stress environment and is dependent on the availability of animals requiring the procedure. A veterinary thoracocentesis simulator has been created to allow students an opportunity for repetitive practice in a low-stakes environment. This study evaluated the face, content, and construct validity of the thoracocentesis simulator. Face and content validation were confirmed by survey results, and construct validity was assessed through comparison of student and veterinarian performance on the simulator. Students' median checklist and global rating scores were significantly lower than those of the veterinarians, and students took significantly longer to perform the procedure, indicating that the simulator was able to differentiate the relative expertise of the user and establishing construct validity. This study supported the use of the thoracocentesis simulator for educators to demonstrate proper technique, for students to practice the steps needed to perform the procedure and experience an approximation of the tactile aspects of the task, and for formative assessment before performing the procedure on client-owned animals.

Authors: Bajan M. , Dařílek P. , Zajac R. , Nečas V.
Published: August 2014

Evolution of VVER-440 fuel assembly is characterised by gradual increase of discharged fuel burn-up and prolongation of fuel cycle. Mentioned effects can be reached effectively by fuel enrichment raise and by parasitic absorption reduction. Both methods were used during VVER-440 fuel assembly optimisation, described at this paper. Enrichment interval was enlarged up to 5.95 % 235U, parasitic absorption was limited by carcass frame of the assembly. Basic characteristics of the best assembly proposals are presented and effects on equilibrium fuel cycle of VVER-440 reactor are characterised.
Comparison analysis of effectiveness of diagnostic methods of local coolant boiling in WWER core
Authors: Semchenkov Y. , Milto V. , Shumskiy B. , Vorobyeva D.
Published: August 2014

The method developed by the Kurchatov Institute's WWER reactor department to detect local coolant boiling in the reactor core on the basis of the neutron noise analysis is currently being implemented at some WWER-1000 units within their regular in-core noise diagnostic systems. Given that WWER-1000 power uprating – as well as new designs being developed, such as AES-2006 and WWER-TOI characterized with higher core power and coolant temperature – would increase the probability of coolant boiling, the efficiency of the available boiling diagnostics method was to be re-evaluated. On the basis of relevant computations, it was suggested to modify the diagnostic model and introduce new parameters to improve the reliability of local boiling detection. Computations simulating in-core boiling were thus performed and showed that the improved method was quite efficient. This paper discusses the possibilities to detect – using the improved method – various in-core coolant boiling cases anticipated for WWERs.
Assessment of the uncertainties of COBRA sub-channel calculations by using a PWR type rod bundle and the OECD NEA UAM and the PSBT benchmarks data
Authors: Panka I. , Keresztúri A.
Published: August 2014

The assessment of the uncertainties of COBRA-IIIC thermal-hydraulic analyses of rod bundles is performed for a 5-by-5 bundle representing a PWR fuel assembly. In the first part of the paper the modeling uncertainties are evaluated in the term of the uncertainty of the turbulent mixing factor using the OECD NEA/NRC PSBT benchmark data. After that the uncertainties of the COBRA calculations are discussed performing Monte-Carlo type statistical analyses taking into account the modeling uncertainties and other uncertainties prescribed in the OECD NEA UAM benchmark specification. Both steady-state and transient cases are investigated. The target quantities are the uncertainties of the void distribution, the moderator density, the moderator temperature and the DNBR. We will see that – beyond the uncertainties of the geometry and the boundary conditions – it is very important to take into account the modeling uncertainties in case of bundle or sub-channel thermo-hydraulic calculations.

Published: August 2014

The paper presents an uncertainty and sensitivity (U&S) study of the VVER-1000 reactor hydraulic properties. It is based on the OECD/NEA coolant transient Benchmark (K-3) on measured data at Kalinin-3 Nuclear Power Plant (NPP) [1]. The novelty of the work consists of taking into consideration all hydraulic uncertainty parameters used in the modeling of the reactor pressure vessel (RPV) internals. A detailed parallel channel ATHLET model of the RPV is developed. It consists of ca. 26 600 control volumes most of them connected with junctions for cross flows. The specific geometry of the gap between upper part of the baffle and upper part of fuel assembly and also a fuel assembly head is taken explicitly into account The influence of the input parameters on the sensitivity and uncertainty of the RPV outlet and inlet temperatures and mass flows as well assembly-wise mass flow and coolant temperature axial distributions is shown.

Published: August 2014

In this paper steps of calculations for a bare rod bundle and so-called swirl type spacer grid are showed and the effects of choice of model details are examined. The modeled pin bundle and spacer grid geometry are related to rectangular western type PWR fuel assemblies. First a CFD model has been developed for a subchannel of the MATIS-H test facility in order to carry out a mesh independence study. Based on the results a model for the half cross-section of the test bundle has been developed and calculations are carried out with different turbulence models. Translational periodicity is applied in axial direction in order to calculate a fully developed flow, which will be used as inlet boundary condition for spacer grid calculations. Results are compared with LDA (Laser Doppler Anemometry) measurements published in the frame of the OECD NEA MATIS-H benchmark. As a last step a model for rod bundle incorporating swirl type spacer grid is developed and calculations are carried out with different turbulence models using the results of the bare rod bundle simulations as inlet boundary conditions.
