    Full Text Available Sha Shen Mai Men Dong Tang (SMD-2; 沙參麥冬湯 shā shēn mài dōng tāng is a Chinese medicinal herb (CMH; 中草藥 zhōng cǎo yào used to treat symptoms associated with cancer therapy. The objective of this study was to assess the effect of SMD-2 on the levels of urinary copper (Cu, zinc (Zn, and selenium (Se in lung cancer patients and head and neck cancer patients receiving chemoradiotherapy. Forty-two head and neck cancer patients and 10 lung cancer patients participated in our clinical trial. Each patient received chemoradiotherapy for 4 weeks. In addition, each patient was treated with SMD-2 for 8 weeks, including 2 weeks prior to and after the chemoradiotherapy treatment. Comparison of urinary Cu, Zn, and Se levels and the ratios of Zn to Cu and Se to Cu at three time points in the two types of cancer were assessed using the generalized estimating equations (GEEs. After the patients received chemoradiotherapy for 4 weeks, SMD-2 treatment was found to be associated with a significant decrease in urinary Cu levels, whereas urinary Zn and Se levels increased significantly. In addition, the ratios of Zn to Cu and Se to Cu in the urine samples of these patients also increased significantly. Both the urinary Zn levels and the ratio of Zn to Cu in head and neck cancer patients were significantly higher than in lung cancer patients. Urinary Zn and Se levels and the ratios of Zn to Cu and Se to Cu, but not urinary Cu levels, increased significantly during and after treatment when assessed using the GEE model. The SMD-2 treatments significantly increased Zn and Se levels in the urine of head and neck cancer patients. Increased Zn and Se levels in urine strengthened immune system.

    Full Text Available Este artigo é decorrente de uma etnografia online sobre o barebacking (sexo anal desprotegido de forma intencional no cenário brasileiro, entre os anos de 2004 e 2007. Mais especificamente, busca discutir a prática e sentidos do barebacking entre homens soropositivos que fazem sexo com homens, considerando as implicações e conflitos vividos por eles a partir do momento em que se descobrem soropositivos após o engajamento no sexo bareback. Para tal, utilizamos relatos produzidos em entrevistas abertas no MSN messenger, após a criação de uma página no orkut e participação em suas comunidades sobre o barebacking. Apresentamos histórias de três homens, de diferentes regiões do país, que praticavam o barebacking e passaram pelo processo da soroconversão. Nessas breves histórias, destacamos algumas tensões ou ambiguidades diante dos prazeres e das proibições ligados ao sexo sem camisinha, incluindo a culpa pelo engajamento no sexo desprotegido e o sentimento de liberdade produzido pelo mesmo.

  9. Geomorphic and Structural Evidence for Rolling Hinge Style Deformation in the Footwall of an Active Low Angle Normal Fault, Mai'iu Fault, Woodlark Rift, SE Papua New Guinea

    While shown to operate in oceanic crust, rolling hinge style deformation remains a debated process in metamorpic core complexes (MCCs) in the continents. The model predicts that unloading and isostatic uplift during slip causes a progressive back-tilting in the upper crust of a normal fault that is more steeply dipping at depth. The Mai'iu Fault in the Woodlark Rift, SE Papua New Guinea, is one of the best-exposed and fastest slipping (probably >7 mm/yr) active low-angle normal faults (LANFs) on Earth. We analysed structural field data from this fault's exhumed slip surface and footwall, together with geomorphic data interpreted from aerial photographs and GeoSAR-derived digital elevation models (gridded at 5-30 m spacing), to evaluate deformational processes affecting the rapidly exhuming, domal-shaped detachment fault. The exhumed fault surface emerges from the ground at the rangefront near sea level with a northward dip of 21°. Up-dip, it is well-preserved, smooth and corrugated, with some fault remnants extending at least 29 km in the slip direction. The surface flattens over the crest of the dome, beyond where it dips S at up to 15°. Windgaps perched on the crestal main divide of the dome, indicate both up-dip tectonic advection and progressive back-tilting of the exhuming fault surface. We infer that slip on a serial array of m-to-km scale up-to-the-north, steeply S-dipping ( 75°) antithetic-sense normal faults accommodated some of the exhumation-related, inelastic bending of the footwall. These geomorphically well expressed faults strike parallel to the main Mai'iu fault at 110.9±5°, have a mean cross-strike spacing of 1520 m, and slip with a consistent up-to-the-north sense of throw ranging from <5 m to 120 m. Apparently the Mai'iu Fault was able to continue slipping despite having to negotiate this added fault-roughness. We interpret the antithetic faulting to result from bending stresses, and to provide the first clear examples of rolling hinge

    Full Text Available Este estudo transversal analisou os fatores de vulnerabilidade social, individual e programática associados ao baixo conhecimento em HIV/AIDS entre homens que fazem sexo com homens (HSH. A técnica amostral Respondent Driven Sampling (RDS foi utilizada em dez cidades brasileiras. Os escores de conhecimento em HIV/AIDS foram estimados pela Teoria de Resposta ao Item e categorizados em três níveis: alto, médio e baixo conhecimento. O modelo de regressão logística ordinal foi utilizado para a análise. Dentre os 3.746 HSH, encontrou-se 36,6%, 37,4% e 26% com alto, médio e baixo conhecimento, respectivamente. No modelo final, apresentaram associação com o baixo conhecimento: escolaridade ≤ 8 anos, cor da pele não branca, critério de classe econômica C e D-E, idade < 25 anos, ter somente um parceiro sexual e nunca ter feito o teste anti-HIV. É fundamental melhorar o nível de conhecimento sobre HIV/AIDS entre os jovens HSH, com condições socioeconômicas desfavoráveis. Intervenções focadas nos fatores de vulnerabilidade programática podem contribuir para a redução dos fatores individual e social.

    Full Text Available A transmissão sexual do Vírus da Imunodeficiência Humana (HIV representa um problema de saúde pública em todo o mundo, e homens que fazem sexo com homens encontram-se sob risco diferenciado para essa infecção. Ainda que existam evidências suficientes para se afirmar que o HIV pode ser transmitido via sexo oral, a percepção desse risco é ambígua, e relaciona-se de forma paradoxal com mudanças de atitude. Novos modelos de percepção de risco devem ser desenvolvidos em diversas áreas de conhecimento para se alcançar compreensão aprofundada desse fenômeno.Sexual transmission of the human immunodeficiency virus (HIV continues to pose a public health problem worldwide. Men who have sex with men are still at differential risk of infection. Although there is evidence to claim that HIV can be transmitted by oral sex, the perception of this risk is ambiguous and relates paradoxically to behavior change. New models of risk perception must be developed in various areas of knowledge to obtain a fuller understanding of this phenomenon.

    Full Text Available This paper focuses on recent trends in risky sexual practices for HIV/AIDS among men who have sex with men (MSM in Fortaleza, Ceará State, Brazil. Four cross-sectional surveys were conducted (1995, 1998, 2002, and 2005 among MSM 14 years or older who reported oral or anal sex in the previous 12 months. Sexual practices were considered risky whenever the respondent reported unprotected receptive or insertive anal intercourse in the six months preceding the interview. Different selection techniques were used to recruit the study population: snowball (1995, 1998, 2002 - 32%; time-space sampling (2002 - 68%; and respondent-driven sampling (2005. Analyses were based on the comparison between proportions. High rates of risky sexual practices were reported in 1995 (49.9%, decreasing in 1998 (32.6%, increasing again in 2002 (51.3%, and showing the lowest level in 2005 (31.4%. Participants with more schooling increased their risky practices from 1998 to 2002, decreasing in 2005. Among individuals with medium or low schooling, risky behavior declined from 2002 to 2005. The article highlights the need for behavioral surveillance to properly address STD/HIV prevention.Estudaram-se as tendências recentes das práticas sexuais de risco para DST/AIDS entre homens que fazem sexo com homens (HSH em Fortaleza, Ceará, Brasil.

Foram analisadas as edições de três jornais portugueses, de 2008 a 2011, resultando num corpus de 266 (4,2% artigos, que foram classificados de acordo com as seguintes variáveis: as fontes de informação citadas (o seu estatuto e especialidade, no caso dos médicos; os temas que são tratados; as características de enquadramento da informação publicada (tom, género jornalístico; e a presença e número de fontes de informação. Pela análise de conteúdo quantitativa, apurou-se que esse tema está em crescimento, essencialmente com notícias de tom negativo e fontes de informação habitualmente identificadas. Não há evidência para afirmar que a periodicidade e a orientação editorial expliquem as variações dessas características, a não ser relativamente ao número de fontes citadas. Vigoram as notícias centradas nos resultados dos erros (mortes ou lesões, provocados por "erros de omissão" e por "erros de comissão", envolvendo uma diversidade de protagonistas: são, tal como acontece na informação sobre saúde em geral, fontes oficiais e especializadas do campo da saúde.

    Full Text Available O início da vida escolar da criança é marcante tanto para pais quanto para professores. É comum que ao ingressar no ambiente escolar, as crianças vivenciem novas experiências e relações sociais distantes do ambiente familiar, demonstrando assim comportamentos, tais como: choro, timidez e mordidas. O presente trabalho tem como objetivo analisar a opinião dos pais e responsáveis de crianças na faixa etária de 18 meses a 2 anos em relação à mordida no ambiente escolar. Diante esta situação, a psicóloga clínica e escolar Hennemann (2004 explica: “Esta é uma manifestação de desenvolvimento considerada impulsiva e exploratória”. Este comportamento aparece e desaparece à medida que a criança amadurece e encontra outras formas de exploração do ambiente. Freud (1920 explica que a fase oral é o período em que a criança sente necessidade de levar à boca tudo o que estiver ao seu alcance, pois o prazer vital está ligado à nutrição. Ela experimenta o mundo com o que conhece melhor: a boca. Outra razão é a necessidade de se comunicar. A metodologia utilizada nesse trabalho utilizou a abordagem qualitativa e quantitativa. Foram analisadas 26 entrevistas realizadas com os pais dos alunos do pré-maternal do CENSA. O período de adaptação escolar é o período em que as mordidas mais acontecem por isso nessa época sua intervenção deve ser maior. Diante dos resultados obtidos, observamos que muitos pais apesar de entender que a mordida faz parte desta faixa etária, mostram-se desconfortáveis com esta situação e buscam junto à escola, estratégias capazes de minimizar esta atitude da criança. Não veem a mordida como algo natural, mas também não supervalorizam o ato como violência. Buscam entender o contexto onde geralmente aconteceu a situação e agem junto aos professores, seguindo as orientações da escola. Constatamos que a parceria entre escola e família é o elemento fundamental para garantir que esta

    2014-12-01

    Full Text Available Apesar de ainda pouco estudada no Brasil, a influência da religião na sexualidade tem sido investigada pela literatura internacional por mais de meio século. Na literatura brasileira, a religião enquanto variável de interesse demográfico, com impacto no comportamento sexual, vem ganhando importância à medida que se fazem presentes, na sociedade, as mudanças no panorama religioso e nas normas e valores associados à sexualidade. Diante do crescente interesse, por parte dos demógrafos, na variável religião, tornam-se necessários mais subsídios teóricos com a finalidade de dar suporte às futuras pesquisas e estudos brasileiros. O presente trabalho busca, então, mapear as literaturas nacional e internacional acerca da associação entre religião, religiosidade e iniciação sexual de adolescentes e jovens e revelar as muitas formas utilizadas ao longo dos anos para classificar religião e religiosidade. Esta análise também procura ressaltar os cuidados metodológicos que devem ser tomados em estudos de sexualidade adolescente e de religião em geral. Para cumprir com esses dois objetivos, foi realizada uma revisão bibliográfica sistemática nas bases de dados SciELO, Atla, JSTOR e Banco de Teses e Dissertações do Cedeplar e da UFMG, buscando artigos publicados entre 1950 e abril de 2014, em português e inglês.

    Full Text Available Em O Instinto da Linguagem, Steven Pinker discorre sobre sua célebre tese: a linguagem não é a mais prodigiosa invenção cultural humana. Ela é uma peça da constituição biológica do cérebro. A linguagem é uma habilidade complexa e especializada, que se desenvolve espontaneamente na criança, sem qualquer esforço consciente ou instrução formal, que se manifesta sem que se perceba sua lógica subjacente, que é qualitativamente a mesma em todo indiví­duo, e que difere de capacidades mais gerais de processamento de informações ou de comportamento inteligente. Para Pinker, a concepção de linguagem como um tipo de instinto transmite a idéia de que as pessoas sabem falar mais ou menos da mesma maneira que as aranhas sabem tecer suas teias. Ele apóia suas idéias em Darwin e Chomsky. Palavras-chave linguagem, gramática universal, evolução Abstract In Language Instinct, Steven Pinker argues about his famous thesis: language is not the most prodigious human cultural invention. It is a distinct piece of the biological constitution of the brain. Language is a complex, specialized skill, which develops spontaneously in the child, without conscious effort or formal instruction. It reveals itself without awareness of its underlying logic, which is qualitatively the same in every individual, and which is distinct from more general abilities of information processing of intelligent behavior. According to Pinker, the conception of language as a kind of instinct conveys the idea that people know how to talk in more or less the same way as spiders know how to spin webs. His thesis is founded in Darwin and Chomsky-s theories. Keywords language, universal grammar, evolution

    Full Text Available O objetivo deste trabalho é investigar a relação entre adoção de cuidados à saúde entre mulheres que fazem sexo com mulheres e as representações relativas a gênero, sexualidade e ao corpo. O estudo utilizou observação etnográfica e entrevistas em profundidade, realizadas entre 2003 e 2006, com trinta mulheres entre 18 e 45 anos, de diferentes segmentos sociais, trajetórias e identidades sexuais, residentes na grande São Paulo, Brasil. A análise do material aponta maior dificuldade em acessar cuidados ginecológicos entre mulheres das camadas populares; que nunca tiveram sexo com homens ou que possuem uma gramática corporal masculinizada. Não só as representações e as experiências negativas em relação aos serviços de saúde, mas também as construções identitárias relativas a gênero e sexualidade estão relacionadas às dificuldades em acessar cuidados à saúde. Embora boa parte da bibliografia internacional a respeito enfatize a relação entre homofobia e menor acesso a serviços, os resultados sugerem que apesar de as situações envolvendo discriminação constituírem realidade, elas não foram consideradas impedimentos para a busca de cuidado, estando muito mais associadas ao relato das práticas e preferências eróticas nos serviços.This article focuses on the relationship between health care for women who have sex with women and representations of gender, sexuality, and the body. The study used ethnographic observation and in-depth interviews held from 2003 to 2006, with 30 women ranging from 18 to 45 years of age, belonging to different social segments, backgrounds, and sexual identities, living in Greater Metropolitan São Paulo. Analysis of the material pointed to greater difficulty in accessing gynecological care for lower-income women, those who had never had sex with men, or those with masculine body language. Not only the negative representations and experiences in relation to health services, but

    Full Text Available Em um primeiro plano, é imprescindível reafirmar que a assistência à saúde depende diretamente dos trabalhadores deste setor e da capacidade dos mesmos para a produção do cuidado. Mesmo considerando que hoje a medicina e a atenção à saúde estão impregnados por noções que supervalorizam as máquinas, os exames e as tecnologias duras, é necessário enfatizar que saúde se faz com e para as pessoas, sendo determinante a atuação dos profissionais de saúde para se estabelecer o sucesso de um modelo de atenção. Também deve ser pontuado que há deficiências, quantitativas e qualitativas, na formação de diversas profissões da saúde no Brasil, e que estas profissões são fundamentais na constituição da equipe para uma atenção integral. A equipe de saúde deve ofertar um cuidado abrangente, ser resolutiva e capaz de atender o maior volume dos problemas de saúde apresentados pela população de um determinado território. É por esta razão que as equipes devem ser suficientes, qualificadas e bem distribuídas, efetivando o acesso universal da população residente em toda a extensão do país, nos moldes definidos para o direito constitucional dos brasileiros. Há evidências suficientes na literatura que mostram o tamanho desse desafio e o drama dos gestores municipais quanto ao provimento dos profissionais, com claro destaque sobre maiores dificuldades em relação aos médicos.

    Traffic crashes result in a loss of life but also impact the quality of life and productivity of crash survivors. Given the importance of traffic crash outcomes, the issue has received attention from researchers and practitioners as well as government institutions, such as the European Commission (EC). Thus, to obtain detailed information on the injury type and severity of crash victims, hospital data have been proposed for use alongside police crash records. A new injury severity classification based on hospital data, called the maximum abbreviated injury scale (MAIS), was developed and recently adopted by the EC. This study provides an in-depth analysis of the factors that affect injury severity as classified by the MAIS score. In this study, the MAIS score was derived from the International Classification of Diseases. The European Union adopted an MAIS score equal to or greater than 3 as the definition for a serious traffic crash injury. Gains are expected from using both police and hospital data because the injury severities of the victims are detailed by medical staff and the characteristics of the crash and the site of its occurrence are also provided. The data were obtained by linking police and hospital data sets from the Porto metropolitan area of Portugal over a 6-year period (2006-2011). A mixed logit model was used to understand the factors that contribute to the injury severity of traffic victims and to explore the impact of these factors on injury severity. A random parameter approach offers methodological flexibility to capture individual-specific heterogeneity. Additionally, to understand the importance of using a reliable injury severity scale, we compared MAIS with length of hospital stay (LHS), a classification used by several countries, including Portugal, to officially report injury severity. To do so, the same statistical technique was applied using the same variables to analyze their impact on the injury severity classified according to LHS

    Full Text Available Resumo O sagrado e o útil encontram-se intimamente associados no Xangô de Pernambuco. O processo de iniciação coincide largamente com a busca da cura, enquanto os sacrifícios são ao mesmo tempo bons para rezar e para comer. Não existe portanto, ao contrário do que poderia pretender uma interpretação demasiadamente literal da sociologia da religião de Durkheim, uma separação radical entre o sagrado e o profano. Há entretanto, na experiência religiosa do Xangô, um momento em que o sagrado paira acima de toda análise funcional, transformando-se desta maneira no mais-que-sagrado, que transparece na festa e no transe extático. E é dessa experiência transcendente, implicando na comunhão emocional do grupo de culto, que surge a identidade mais íntima de cada fiel.

    Full Text Available OBJETIVO: Caracterizar o consumo alimentar mais frequente da população brasileira. MÉTODOS: Foram analisados dados referentes ao primeiro dia de registro alimentar de 34.003 indivíduos com dez anos ou mais de idade que responderam ao Inquérito Nacional de Alimentação, composto por amostra probabilística da Pesquisa de Orçamentos Familiares 2008-2009. O padrão de consumo foi analisado segundo sexo, grupo etário, região e faixa de renda familiar per capita. RESULTADOS: Os alimentos mais frequentemente referidos pela população brasileira foram arroz (84,0%, café (79,0%, feijão (72,8%, pão de sal (63,0% e carne bovina (48,7%, destacando-se também o consumo de sucos e refrescos (39,8%, refrigerantes (23,0% e menor presença de frutas (16,0% e hortaliças (16,0%. Essa configuração apresenta pouca variação quando se consideram os estratos de sexo e faixa etária; contudo, observa-se que os adolescentes foram o único grupo etário que deixou de citar qualquer hortaliça e que incluiu doces, bebida láctea e biscoitos doces entre os itens mais consumidos. Alimentos marcadamente de consumo regional incluem a farinha de mandioca no Norte e Nordeste e o chá na região Sul. Houve discrepâncias no consumo alimentar entre os estratos de menor e maior renda: indivíduos no quarto de renda mais elevada referiram sanduíches, tomate e alface e aqueles no primeiro quarto de renda citaram os peixes e preparações à base de peixe e farinha de mandioca entre os alimentos mais referidos. CONCLUSÕES: Existe um padrão básico do consumo alimentar no Brasil que inclui entre os alimentos mais consumidos arroz, café, feijão, pão de sal e carne bovina, associado ao consumo regional de alguns poucos itens. Particularmente entre os adolescentes, alimentos ricos em gordura e açúcar são também de consumo frequente.

    Hip fracture is a major health problem in Thailand. This study attempted to examine the incidence, related factors, and trends of hip fracture in Chiang Mai, Thailand. All hip fracture data among patients aged 50 yr or older were collected from hospitals in Chiang Mai, Thailand from August 1, 2006 to July 3, 2007. Data from the 1997 Chiang Mai hip fracture study were used for comparison. In the study period, 690 hip fractures were reported: 203 males and 487 females (male to female ratio was 1 to 2.4), with a mean age of 76.7 yr. The estimated cumulative incidence was 181.0 per 100,000, and the adjusted incidence was 253.3 (males: 135.9; females: 367.9). A simple fall was the most common mechanism (79%) of fracture, and 80% of the hip fractures occurred in patients aged 70 yr or older. The highest incidence of hip fracture was observed in patients older than 85 yr (1239). At 6 mo postfracture, most patients (61%) used a walking aid. Compared with the 1997 data, hip fracture incidence had increased by an average of 2% per yr, and the incidence of hip fracture had increased significantly from August 1, 2006 to July 31, 2007, especially in patients older than 75 yr. In patients older than 84 yr, the incidence increased by a factor of 2. Urgent strategies for the prevention and treatment of osteoporosis, and hence hip fracture, are needed.

    Full Text Available Assinaturas são os grafismos mais efetuados pelas pessoas, por demonstrar conhecimento e concordância a documentos diversos. O exame grafoscópico de assinaturas disfarçadas é uma das determinações mais difíceis de proceder na Documentoscopia. Os disfarces podem confundir os peritos e conduzir a erros quanto à autoria de assinaturas. O objetivo deste trabalho foi identificar as características mais frequentes encontradas em análises grafoscópicas de assinaturas disfarçadas. Foi solicitado a 102 voluntários que assinassem sua assinatura habitual por cinco vezes e, então, que tentassem disfarçar sua assinatura. Posteriormente, realizou-se o confronto gráfico entre as assinaturas padrão e as disfarçadas, e as alterações encontradas foram anotadas, sendo que as mais frequentes foram: modificações da forma de letras maiúsculas e minúsculas, de dimensão e calibre, na forma e na posição de ataques e remates, na quantidade de levantamentos da caneta durante a escrita (andamento gráfico e a alteração ou supressão de símbolos ou caracteres especiais. Esses dados podem ajudar os peritos a identificar características gráficas indicativas de disfarces, quando da verificação de autenticidade. Por outro lado, observou-se que características alteradas com menor frequência surgem em assinaturas disfarçadas e podem levar a uma conclusão errônea no sentido da falsificação do lançamento gráfico.

    2014-01-06

    Multivariate generalized Gaussian density (MGGD) is used to approximate the multiple access interference (MAI) and additive white Gaussian noise in pulse-based ultrawide bandwidth (UWB) system. The MGGD probability density function (pdf) is shown to be a better approximation of a UWB system as compared to Gaussian, Laplacian and Gaussian-Laplacian mixture (GLM). The similarity between the simulated and the approximated pdf is measured with the help of modified Kullback-Leibler distance (KLD). It is also shown that MGGD has the smallest KLD as compared to Gaussian, Laplacian and GLM densities. Finally, a receiver based on the principles of minimum bit error rate is designed for the MGGD pdf.

    Full Text Available É possível entender que o aumento de pessoas idosas no mundo requer uma perspectiva transcultural da adultez e da velhice. Assim, este estudo exploratório procurou compreender a dinâmica cultural de uma comunidade indígena, destacando o papel da pessoa mais velha. Para tal foram realizadas entrevistas abertas com roteiro semi-estrurado com seis interlocutores do Conselho de Anciãos do povo Guarani-Mbyá, de uma tradicional aldeia de São Paulo que se dispuseram a participar; e outras informações e impressões foram registradas ao longo da pesquisa num diário de campo. A análise do conteúdo sugeriu que "ser Guarani-Mbyá" é um modo de viver e estar, orientado para a preservação da tradição através da educação e religião; o papel dos mais velhos como guardiões e transmissores das tradições. Os resultados contribuem para olhar o envelhecimento sob outras perspectivas culturais.

    Full Text Available “Cartografia Geográfica” designa o campo da formação superior em Geografia que se dedica à cartografia. Ao se considerar as diversas possibilidades de cartografias e espacialidades que coexistem no contemporâneo, propõe-se entender este campo num “entre” o “já-estabelecido” e o “não mais suficiente”. Ambos os domínios, tomados separadamente, podem ser considerados como despotencializadores da cartografia na Geografia. Contudo, no “entre” os dois domínios pode ser situada a pertinência e a riqueza de se fazer e pensar a cartografia na geografia na atualidade. O propósito deste texto é trazer elementos para dar visibilidade ao “entre” mencionado. Parte-se inicialmente de uma discussão sobre a linguagem e sobre os caminhos da semiótica cartográfica que, ao se inspirar na linguística estrutural voltou-se para dentro do mapa (arranjos de signos, imprimindo um modelo fortemente representacional para a cartografia, aqui identificado como o “já-estabelecido”. A seguir são apresentadas ideias de alguns autores contemporâneos que trazem abordagens pós-representacionais, que ressituam a relação entre a ciência (cartografia e seu objeto (o mapa, pois, face às modificações contemporâneas de entendimento da espacialidade, o “já-estabelecido” passa a ser “não mais suficiente”. Nas considerações finais são delineadas algumas estratégias para se habitar este “entre” como potência criativa para expansão do campo da Cartografia geográfica.

    Hip fractures are a major public health problem. Patients who have suffered a hip fracture have an increased risk of a subsequent hip fracture. This study examines the incidence ofsecondhip fractures and attempts to identify underlying risk factors. To examine the incidence ofsecond hip fractures in osteoporotic patients at Chiang Mai University Hospital and to identify risk factors related to second hip fractures. A retrospective review was conducted of all low-energy mechanism hip fracture patients admitted during 2008 and 2009. Analysis of second hip fractures was conducted using survival analysis and logistic regression analysis. A total of 191 patients were observed for 391.68 person-years (mean 2.05 person-years per patient). Among that group, nine second hip fractures were identified, an overall incidence rate of 0.023 second fractures per person-year. Second hip fractures tended to occur within the first year following an initial hip fracture. There were no significant differences related to either gender or comorbid medical conditions. Logistic regression analysis revealed that increased risk of a second hip fracture was associated with age (highest between 80 to 89 years) and patients who were not treated for osteoporosis following their initial fracture. The incidence of second hip fractures at Chiang Mai University Hospital was 0.023 per person-year Careful follow-up of older patients, especially those over 80, and treatment ofosteoporosis with bisphosphonate plus vitamin D and calcium supplements was correlated with a reduction in the incidence of second hip fractures.

    The atomic energy applications in Faculty of Medicine, Chiang Mai University (CMU) are mainly performed by department of Radiology that is divided into three dicisions: 1) Diagnostic Radiology Division for the applications of X-rays, ultrasound, and magnetic resonance, 2) Therapeutic Radiology and Oncology Division for cancer treatments by photon accelrator and external radionuclides therapy or brachytherapy, 3) Nuclear Meddicine Division for clinical dignosis by using radionuclide scintigraphy, targeted molecular imaging and internal radionuclide therapy. In the last decade, many advanced medical images for clinical diagnosis included of digital & computed radiology (DR & CR), digital subtraction angiography (DSA) and images (DSI), computed tomography (CT) with dual X-rays energies, manetic resonance imaging (MRI), and hybrid images of SPECT/CT were established in Radiology Department and PET/CT Cyclitron Center Chiang Mai University (PCCMU), respectively. For cancer treatments, the frontier technologies in radiation oncligy therapy such as tomotherapy, IMRT, 3D conformal radiation treatment, stereotactic radiationtherapy (SRT), stereotactic radiation surgery (SRS), and radiation biology laboratory were implemented in the department as well. As far as fast development of nuclear technology in medicine, future implementation of advanced nuclear applications in medicine strongly need an intergrated knoowledge from many specialties e.g. computer softeare in image reconstruction, accuracy and and precision technology, production of specific radiotracers for molecular imaging and therapy, techniques in radionuclide productions, innovation of new wquipment or materials for radiationprotection and safety, etc. However the most important factors of nuclear applications in medicine are the vision, mission and the value statements of the organization on the high cost in radiology investment and human resources development.

    Colour control is a specific tool to identify local environment. Especially in the historic area or conservation area, to promote colour control is very necessary. Therefore, there are many standards of colour to control such as Munsell, colour name, and L*a*b*. This research is aimed to analyze the appropriate colour control by using a Munsell standard colour which is suitable to visual perception. The study area is scoped in northern region of Lanna culture in Thailand which nowadays used names of colours to control. Chiang Mai and Lamphun are selected to be case study because they are in a center of Lanna Empire of Thailand and have many historic significant things such as city wall, temple, monastery, palace, and city moat. The mainly procedure conducts in this article is based on the analysis of material colour. The study chose local natural materials which are used in the historic significant things. Earthen clay tile, wooden roof tile, burnt clay brick, laterites, hard wood, bamboo, silver, and gold are evaluated. The procedure used the DIC application of android processor on smart phone. This application has a conversion data to switch a colour value from pick-up point in photo to many colour values such as RGB, CMYK which Munsell value is included. The photos were taken within the historic area of Chiang Mai and Lamphun by random. The result can scope a range of colours of Munsell standard of natural colour (N), red (R), yellow (Y), and yellow-red (YR). A natural colour (N) can be suggested a range 1.0-9.0 (N 1.0-9.0). Red can be ranged the value between 3.0-7.0 and chroma between 3.0-9.0 (R 3.0-7.0/3.0-9.0). Yellow can be ranged the value between 6.0-9.0 and chroma between 4.0-12.0 (Y 6.0-9.0/4.0-12.0). Yellow-red can be ranged the value between 2.0-8.0 and chroma between 2.0-11.0 (YR 2.0-8.0/2.0-11.0). The results can be revealed a process of colour analysis of historic colour control and may offer to be an ordinance in further.

    To identify variables associated with the acceptance of HPV vaccination among Thai parents/primary caregivers. The present prospective cross-sectional study recruited the parents/caregivers of female adolescents aged 12-18 years from schools in Chiang Mai, Thailand, between January 1 and February 29, 2016. A four-part questionnaire was distributed to assess demographics, HPV vaccine acceptance, knowledge, and beliefs toward HPV and cervical cancer. Predictors of HPV vaccine acceptance were determined by logistic regression analysis. The study enrolled 331 parents; more than half (195 [61.1%]) had heard of HPV vaccines. Their knowledge related to HPV and cervical cancer was moderate. A majority of parents (266/313 [85.0%]) indicated they would accept HPV vaccination if the costs were subsidized by the government. Acceptance of HPV vaccines was associated with perceived benefits of HPV vaccination (odds ratio [OR] 1.49; 95% confidence interval [CI] 1.18-1.88), perceived susceptibility to disease (OR 1.42; 95% CI 1.11-1.81), and household income (OR 1.35; 95% CI 1.02-1.78). Parental beliefs have an important role in their acceptance to vaccinate their daughters. These potentially modifiable beliefs offer strategies for future interventions designed to increase uptake for future HPV vaccination campaigns. © 2018 International Federation of Gynecology and Obstetrics.

    Clouds play very important role in the variation of surface solar radiation and rain formation. To understand this role, it is necessary to know the physical and geometrical of properties of cloud. However, clouds vary with location and time, which lead to a difficulty to obtain their properties. In this work, a ceilometer was installed at a station of the Royal Rainmaking and Agricultural Aviation Department in Chiang Mai (17.80° N, 98.43° E) in order to measure cloud base height. The cloud base height data from this instrument were compared with those obtained from LiDAR, a more sophisticated instrument installed at the same site. It was found that the cloud base height from both instruments was in reasonable agreement, with root mean square difference (RMSD) and mean bias difference (MBD) of 19.21% and 1.58%, respectively. Afterward, a six-month period (August, 2016-January, 2017) of data from the ceilometer was analyzed. The results show that mean cloud base height during this period is 1.5 km, meaning that most clouds are in the category of low-level cloud.

    The authors evaluated the results of treating hyperthyroidism with 131 I. Patient selection for tre treatment is based on clinical features and laboratory test results such as thyroid uptake, scintigraphy and RIA determinations of thyroid hormones. The average dose is 6.2±1.1 m Ci (that is 233.1±40.7 MBq). The average number of doses is 1.3 for one patient. The results are as follows: - Euthyroid status after 4 years follow-up from the 1 31 I dose administration: 72.3 - Persistent or recurrent hyperthyroidism: 20 %. - Hypothyroid complication appears 6 years after the administration of 1 31 I dose: 14 %. So the cumulative hypothyroid rate is: 2.3 % per year. - Serious complications were not observed in any patient. Hyperthyroidism is a common health problem in Vietnam (1). In the past, only antithyroid drugs and surgery were used. 131 I was first introduced to Vietnam in the Nuclear Medicine Department in Bach Mai in 1971 and thereafter widely applied in the country.

    Full Text Available O objetivo deste trabalho foi avaliar a atividade funcional de macrófagos de ratos diabéticos, através da liberação do ânion superóxido, na presença do composto "mais vida". Os animais foram divididos em dois grupos, controle (N=20 e diabético (N=20. Avaliou-se a glicemia, massa corpórea e a liberação de superóxido pelos macrófagos de baço de ratos. O composto "mais vida" foi obtido através da mistura de extratos de sete plantas, sendo Orbignia martiana Rodr., Tabebuia avellanedae L.G., Arctium lappa L., Rosa centifolia L., Maytenus ilicifolia Mart., Vernonia condensata Baker e Thuja occidentalis L. Observou-se que glicemia foi maior no grupo diabético. A liberação espontânea do ânion superóxido pelos macrófagos foi menor no grupo diabético. O composto "mais vida", independente dos níveis glicêmicos, aumentou a liberação de superóxido dos macrófagos. Quando as células foram estimuladas pelos extratos vegetais isolados, também houve aumento na liberação do ânion superóxido pelos macrófagos em ambos os grupos. As maiores liberações de superóxido ocorreram quando os macrófagos foram estimulados pela Thuja occidentalis L., Rosa centifolia L., Tabebuia avellanedae L.G. e Maytenus ilicifolia Mart. Estes dados sugerem que a ativação de macrófagos pelo composto "mais vida" pode representar um mecanismo alternativo de defesa para infecções em indivíduos diabéticos.This study investigated the effects of "mais vida", a commercial natural mix, on macrophages functional activity as evaluated by the superoxide release in diabetic rats.

Para tanto, percorreu-se na pesquisa bibliográfica e documental 48 obras compiladas, primordialmente, da revista Disability and Society, da Asociación Española de Sociología de la Discapacidad e da base de dados do Centre of Disability Studies da Universidade de Leeds. As obras compiladas foram analisadas por meio de análise categorial. A primeira das categorias identificadas centra-se nas principais interpretações adotadas pelas Ciências da Saúde (paradigma médico para pensar a deficiência; a segunda, em histórias associadas com a constituição da Sociologia da Deficiência - nos movimentos sociais que, em resposta às interpretações da deficiência adotadas pelas Ciências da Saúde, (resignificaram a deficiência e fundaram os Estudos da Deficiência (Disability Studies; e, a terceira, nas múltiplas faces teóricas da Sociologia da Deficiência e nos novos modelos de compreensão da deficiência. A sistematização do conteúdo desvelou um paradigma sociológico de interpretação da deficiência: este paradigma apresenta vozes por significados e práticas mais inclusivas.

    Luiz Gustavo Silva Souza

    Full Text Available O objetivo deste artigo é discutir o papel social da escola sob o ângulo da experiência estudantil e das relações que os alunos estabelecem com as regras. Relatamos um estudo de caso feito a partir de entrevistas com duas alunas ingressantes no ensino médio. Em seu discurso, as alunas criticaram o funcionamento da escola e demandaram mais disciplina e regras mais rigorosas. Em nossa análise, refletimos sobre a construção histórica da escola como instrumento disciplinar. Em seguida, analisamos os sentidos conferidos pelas alunas às experiências escolares, à família, à adolescência, às regras e ao futuro profissional. Discutimos o pedido por mais disciplina feito pelas alunas, tendo em vista, além do contexto sociohistórico, o conjunto de suas práticas, vivências e sentidos subjetivos. Afirmamos que, para construir uma escola capaz de promover autonomia, os educadores precisam considerar esses sentidos subjetivos, e as práticas escolares devem contemplar análises da existência psicossocial. Para concluir, afirmamos que a escola deve sustentar seu lugar de autoridade e referência para os jovens e, ao mesmo tempo, abrir-se para a compreensão e para a incorporação da alteridade.

    2016-05-01

    Full Text Available A escassez de profissionais médicos em determinadas áreas no Brasil é tema que sempre mereceu atenção especial do Estado. O Projeto Mais Médicos para o Brasil, implementado por meio da Medida Provisória nº 621, de 8 de julho de 2013, autoriza a atuação de médicos estrangeiros sob regime especial de aperfeiçoamento profissional no Sistema Único de Saúde (SUS, na Atenção Básica, possibilitando a cobertura médica assistencial em  regiões prioritárias e vulneráveis do país, e foi fruto de questionamento judicial junto ao Supremo Tribunal Federal, por meio de ação direta de inconstitucionalidade, que colocou em confronto os limites constitucionais de autorização para essa forma de atuação profissional. O estudo objetivou identificar os argumentos jurídicos utilizados pelos diversos atores que atuaram nas ADINs 5035-DF e 5037-DF, notadamente no que se refere ao Projeto Mais Médicos para o Brasil, ajuizadas no Supremo Tribunal Federal e analisá-los à luz da Teoria dos Direitos Fundamentais de Robert Alexy. Os resultados apontam que o Projeto, na sua estruturação legal, encontra legitimidade na medida em que não se confunde com a abertura de mercado de trabalho, institui regime específico de atuação profissional, com garantias essenciais dos indivíduos, atenta para diretrizes de cooperação internacional em saúde da Organização Mundial de Saúde (OMS e demonstra eficácia social com a concreta ampliação de acesso da população na cobertura assistencial até que medidas conjunturais e estruturantes da formação médica no Brasil sejam implementadas e alcancem resultados diretos à população usuária do SUS.

    2003-08-01

    É amplamente reconhecido que as pessoas em geral têm grande fascínio e interesse pela Astronomia. Por outro lado, o conteúdo dessa área incluído no ensino formal está longe de ser abrangente e suficiente para suprir a demanda. Esse interesse permite otimizar a divulgação e o ensino não formal de Astronomia aliando a adequação do conteúdo à expectativa das pessoas. Nesse intuito, nosso trabalho busca mapear que assuntos da Astronomia despertam mais a atenção e o interesse das pessoas e o quanto disso é estimulado pela mídia, que freqüentemente aproveita-se desse interesse de forma sensacionalista, trazendo contribuições positivas e negativas. Para esta avaliação, utilizamos as pesquisas específicas e de caracterização do público que freqüentou o MAst nos anos de 2001 a 2003, pesquisa das matérias de Astronomia veiculadas na mídia escrita da cidade do Rio de Janeiro no mesmo período, além da base de dados do programa Pergunte a um astrônomo, realizado no Observatório Nacional nos anos de 1997 a 1999. Para a análise dos dados, dividimos as perguntas em dez categorias, cada uma com suas subcategorias, tomando como referência as divisões, comissões e grupos de trabalho da IAU. Apresentamos neste trabalho os resultados dessa pesquisa, que incluem, entre outros, a predominância de questões nas categorias Observação do Céu e Sistemas Planetários enquanto nos jornais dominam as notícias de Sistemas Planetários e Espaço & Astronáutica. Outro resultado interessante indicou que as dúvidas de crianças do ensino fundamental se concentram em algumas categorias enquanto as questões de adultos são mais distribuídas por todas as categorias. Os resultados dessa pesquisa serão aplicados diretamente no aperfeiçoamento das atividades do Programa de Observação de Céu, bem como na elaboração de novos projetos e eventos realizados no MAst.

  1. Terceirização no Brasil: velhos dilemas e a necessidade de uma ordem mais includente

    Directory of Open Access Journals (Sweden)

    Márcia da Silva Costa

    Full Text Available Resumo Discussão sobre o fenômeno da subcontratação nas organizações contemporâneas. Tal fenômeno é aqui entendido como parte do processo mais amplo de flexibilização das instituições sociais e do trabalho que acompanhou o desmonte do fordismo e tem sido responsável pela fragmentação e precarização dos mercados de trabalho em todos os países industrializados. Adota-se aqui a perspectiva de análise na qual são discutidas as implicações da terceirização para os trabalhadores. À luz das teses da crise da sociedade salarial e da acumulação flexível, cuja referência é encontrada no pensamento da escola da regulação fordista, argumenta-se que a subcontratação, mais conhecida no Brasil como terceirização, reforça as relações de dominação e o controle social sobre a força de trabalho, rebaixando ou retirando direitos historicamente conquistados. Esse processo tem sido muito mais pernicioso em sociedades de democracia recente, como a brasileira, nas quais as novas práticas de flexibilização do trabalho contribuíram para fragilizar, ainda mais, a estrutura do mercado de trabalho, historicamente marcada pelos baixos salários, pela excessiva instabilidade do vínculo empregatício, pela baixa qualificação dos seus trabalhadores, pela fraca organização coletiva, pelos parcos direitos cidadãos. A despeito dos avanços nos indicadores do emprego e da renda na última década no país, a subcontratação tem se disseminado, o que reitera esse padrão predatório de relações de trabalho.

    2018-05-01

    A primary limitation of Direct Sequence Code Division Multiple Access DS-CDMA link performance and system capacity is multiple access interference (MAI). To examine the performance of CDMA systems in the presence of MAI, i.e., in a multiuser environment, several works assumed that the interference can be approximated by a Gaussian random variable. In this paper, we first develop a new and simple approach to characterize the MAI in a multiuser system. In addition to statistically quantifying the MAI power, the paper also proposes a statistical model for both variance and mean of the MAI for synchronous and asynchronous CDMA transmission. We show that the MAI probability density function (PDF) is Gaussian for the equal-received-energy case and validate it by computer simulations.

    2016-01-01

    Full Text Available Um dos principais veículos, se não o principal, para comunicação científica são os periódicos. Portanto, faz sentido estudar uma ou mais revistas científicas. Tais tipos de estudos não são raros na literatura, mesmo na brasileira, podendo citar como exemploMueller e Pecegueiro (2001. Esses estudos são importantes pois apresentam indicadores científicos de produção científica em uma determinada área. Assim, é objetivo do presente trabalho realizar uma análise bibliométrica da revista Navus buscando identificar características significativas da produção científica em gestão e tecnologia. A escolha do referido periódico se justifica primeiramente por publicar majoritariamente trabalhos nacionais, e em segundo por ser uma publicação jovem, trimestral e indexada em importantes bases. Serão apresentados os principais autores, os trabalhos mais relevantes do periódico e as palavras-chave mais utilizadas. Também serão apresentados caminhos para a melhoria da classificação do periódico no sistema Qualis de avaliação da Coordenação de Aperfeiçoamento de Pessoal de Nível superior.

    Full Text Available Partindo da crise do paradigma tradicional e tendo como epicentro a crítica feminista, este trabalho tenta mostrar o desafio que enfrenta a teoria feminista para tornar-se um novo paradigma e para tanto realiza-se uma pesquisa bibliográfica, consubstanciada na literatura pertinente ao tema. Evidencia-se que o desafio de ser um paradigma em ascensão faz com que esta teoria enfrente problemas teóricos, conceituais e metodológicos que precisam de um esforço conjunto para serem aprofundados e resolvidos. Todavia, o desenvolvimento desta teoria não depende apenas do mundo acadêmico, mas está também atrelado a mudanças na estrutura social, pois, de uma sociedade mais igualitária, mais facilmente emergirá um conhecimento sem dominação de gênero.

    The concept of acupuncture point localisation in Traditional Chinese Medicine (TCM) is based on millenary practical experience. Modern imaging methods such as PET, MRI and SPECT have been used primary for the investigation of the mechanisms of action of acupuncture. In this pilot single-case study we have evaluated the technical possibilities for in-vivo imaging of the anatomical relations of acupuncture points using state of the art MRI. Preliminary experiments relating to the quality of acupuncture needles under the setting of MRI were done both with stainless steel and gold needles. In a second step, in-vivo imaging was carried out. A licensed acupuncture practitioner (RM) chose two points belonging to the so-called extraordinary vessels. In 2 sequential, separate procedures, he inserted himself gold acupuncture needles using a neutral technique (known as Ping Bu Ping Xie) into the Dai mai and Shen mai points, i.e. gall bladder 26 and bladder 62. Imaging was done on a Siemens Magnetom Avanto MR scanner using a head array and body coil. Mainly T1-weighted imaging sequences, as routinely used for patient exams, were used to obtain multi-slice images. In the preliminary experiments only acupuncture needles made of gold showed enough stability in order to be used for further imaging procedures. Using an onion and a banana as an object, further studies showed that the gold needles produced a void defect that corresponds to the tip of the inserted needle, while at the same time an artefactually increased diameter was observed. The in-vivo experiments showed that the Dai mai point was in relation to the abdominal internal oblique muscle. The Shen mai point artefact showed up close to the longus and brevis peroneal tendons at the fibular malleolus. Side effects related to heating or burning were not observed. Improved anatomical recognition was obtained using 3D-volume rendering techniques. Through an adequate choice of acupuncture material (gold needles) as well as of

    The infection dynamics of metacercariae were assessed in cyprinoid fish (cyprinoids) from Chiang Mai and Sakon Nakhon Provinces, Thailand, during October 2008 to September 2009. The samples were collected during 3 seasons from rivers and local markets. Metacercarial infection was determined by acid-pepsin digestion and confirmed using HAT-RAPD PCR method. Thirteen and 16 species of cyprinoids were collected from Chiang Mai and Sakon Nakhon with overall prevalences of metacercarial infection of 84.5 and 47.6%, respectively. Haplorchis taichui, Haplorchoides sp, and Centrocestus caninus were found in Chiang Mai and 4 species of metacercariae: H. taichui, Haplorchoides sp, O. viverrini and an unknown trematode species in Sakon Nakhon. H. taichui and Haplorchoides sp metacercariae in 3 species of cyprinoids (Henicorhynchus siamensis, Cyclocheilichthys armatus, Amblyrhynchichthy truncatus) had the highest prevalence (100%) in Chiang Mai, while the highest prevalence (100%) of metacercaria in Sakon Nakhon was Haplorchoides sp in 1 species of cyprinoids (Cyclocheilichthys armatus). The overall prevalence from Chiang Mai Province was highest in the rainy season (95.6%), lower in the hot-dry season (88.1%) and lowest in the cool season (72.5%). In Sakon Nakhon Province the highest prevalence was in the hot-dry season (52.7%), and lower in the rainy and cool season, 44.4% and 43.5%, respectively. The HAT-RAPD profiles confirmed the identity of metacercariae and adult stage of H. taichui, Haplorchoides sp, C. caninus and O. viverrini.

    A preliminary investigation into different eating patterns among Thai consumers who shop at fresh markets as opposed to supermarkets in Chiang Mai. A short questionnaire adopted from a previous study was administered to the forty-four participants, who comprised supermarket users, fresh market users and people who consistently shopped at both supermarkets and fresh markets. Participants were recruited within four fresh markets and two food courts attached to supermarkets in Chiang Mai. Chiang Mai residents who agreed to participate in the study. Equal numbers were regular fresh market and supermarket users. Initial results suggest an association between shopping at supermarkets and attributing bread with culinary value. Supermarkets may be potentially significant players in the 'nutrition transition', providing Thais more convenient shopping at some cost to their healthy food choices.

  9. Interaction of Se and GaSe with Si(111)

    International Nuclear Information System (INIS)

    Meng, Shuang; Schroeder, B. R.; Olmstead, Marjorie A.

    2000-01-01

    Deposition of Se and GaSe on Si(111)7x7 surfaces was studied with low-energy electron diffraction, x-ray photoelectron spectroscopy, and x-ray photoelectron diffraction to probe initial nucleation and interface structure for GaSe/Si(111) heteroepitaxy. Room-temperature deposition of Se on Si(111)7x7 results in an amorphous film. Subsequent annealing leads to Se evaporation without ordering or interdiffusion. Se deposition at 450 degree sign C saturates at submonolayer coverage with no diffusion of Se into the substrate. There is no clear evidence of ordered sites for the Se. Growth of GaSe on Si(111)7x7 above 500 degree sign C results in a pseudomorphic bilayer, with Si-Ga-Se bonding. Additional GaSe does not stick to the bilayer above 525 degree sign C. The resulting Se lone pair at the surface leads to an ideally passivated surface similar to As/Si(111). This stable surface is similar to the layer termination in bulk GaSe. The single domain bilayer is oriented with the Ga-Se bond parallel to the substrate Si-Si bond. (c) 2000 The American Physical Society

    To examine women's embodied knowledge of pregnancy and birth, women's explanations of precautions during pregnancy and birth and preparations for easy birth and the role of a traditional midwife in a Thai birthing care. In-depth interviews relating to traditional and changed beliefs and practices of pregnancy and childbirth with Thai women in Northern Thailand. Chiang Mai city and Mae On sub-district in Chiang Mai province, Northern Thailand. 30 Thai women living in Chiang Mai in Thailand. The social meaning of childbirth in Thai culture is part of the larger social system, which involves the woman, her family, the community, society and the supernatural world. Traditional beliefs and practices in Thai culture clearly aim to preserve the life and well-being of a new mother and her baby. It seems that traditional childbirth practices have not totally disappeared in northern Thailand, but have gradually diminished. Women's social backgrounds influence traditional beliefs and practices. The traditions are followed by most rural and some urban poor women in Chiang Mai. The findings of this study may assist health professionals to better understand women from different cultures. It is important to recognise many factors discussed in this paper within the context of Thai lives and traditions. This will prevent misunderstanding and, consequently, encourage more sensitive pregnancy and birthing care for pregnant women.

    To examine relationships between location, demographics, lifestyle, beliefs, and experience of hot flushes and night sweats (HFNS) amongst women living in two cities in Thailand. Cross-sectional study of peri- and postmenopausal women, aged 45-55 years, from Bangkok and Chiang Mai. Participants completed questionnaires (demographics, health, HFNS (prevalence, frequency and problem-rating) and beliefs about menopause). A sub-sample of women from each location was interviewed. A total of 632 women (320 Bangkok and 312 Chiang Mai) aged 50.88 (standard deviation 3.06) years, took part. The prevalence of HFNS was 65%, average HFNS frequency 8.7 (10.8) per week and problem rating 4.3/10. Women from Chiang Mai had significantly more problematic HFNS, but prevalence and frequency were similar in both sites. Poor general health predicted HFNS prevalence and frequency, while Chiang Mai location, HFNS frequency, age, diet and beliefs about menopause were associated with problematic HFNS. Location remained significant after controlling for education, occupation and age; location was partially explained by beliefs. Qualitative interview responses illustrated the differences in beliefs about menopause between locations. HFNS reports are prevalent with moderate frequency and problem-ratings in these urban centers in Thailand. The results will be included in the broader International Menopause Society study of Climate, Altitude and Temperature (IMS-CAT) of the impact of climate on HFNS.

MÉTODOS: Para o diagnóstico de TAG, foram utilizados os critérios do "Diagnostic and Statistical Manual of Mental Disorders" (DSM-IV. Selecionou-se uma amostra randômica e representativa de 77 sujeitos (35%, residentes em uma comunidade, entre todos os idosos com idade acima de 80 anos do município Veranópolis, RS. Os padrões de sono foram aferidos pelo índice de qualidade de sono de Pittsburgh e pelo diário sobre sono/vigília a ser preenchido ao longo de duas semanas. Cinco testes neuropsicológicos foram usados na avaliação cognitiva: teste das lembranças seletivas de Buschke-Fuld; lista de palavras da bateria CERAD (Consortium to Establish a Registry for Alzheimer's Disease; teste de fluência verbal e dois subtestes da escala de memória Wechsler. RESULTADOS: A prevalência estimada de TAG foi de 10,6%, cuja presença estava associada a uma maior ocorrência de depressão clinicamente diagnosticável, com um significativo maior número de sintomas depressivos, quando medidos pela escala de depressão geriátrica, e com uma maior ocorrência de depressão menor. Os padrões de sono e o funcionamento cognitivo, entre sujeitos com TAG, não estavam afetados. A gravidade das doenças físicas não variava entre sujeitos com TAG e os controles normais. A presença de TAG estava associada a um significativo pior padrão de qualidade de vida relativa à saúde.

    Full Text Available Resumo Resumo Em municípios de pequeno porte, que em geral são situados em áreas geográficas mais isoladas, combinado com situações de maior vulnerabilidade social e econômica, a escassez de médicos é um problema constante. O objetivo deste estudo foi identificar a participação e as características dos municípios de pequeno porte da macrorregião norte do estado do Paraná que aderiram ao Projeto Mais Médico para o Brasil (PMMB. Trata-se de um estudo quantitativo realizado em 82 municípios que utilizou dados primários e secundários. Os resultados revelaram que eram poucos os municípios que possuíam algum critério de adesão (6,1%, mas isso não representou um impedimento para que os demais aderissem ao projeto (75,6%. Os municípios que possuíam menores índices de desenvolvimento humano, que tinham população de mais de cinco mil habitantes, algum critério de adesão e que eram mais afastados, seja da sede da região, seja do município de médio/grande porte mais próximo foram os que mais aderiram ao PMMB. Não se pode negar que o PMMB reduziu de forma significativa a distribuição desigual de médicos no Brasil e na região de estudo. Contudo, a sustentabilidade dessa política precisa estar atrelada ao enfrentamento de outros desafios que ainda persistem no SUS.

    Full Text Available A metáfora da distância cultural vem dominando a área de estudos transculturais há mais de quatro décadas por meio de uma visão centrada, sobretudo, no interesse econômico e nas diferenças culturais entre países. O uso dessa metáfora se fundamenta em epistemologia positivista e adota lentes de uma visão estreita; embora, paradoxalmente, seja aplicada à área internacional. O objetivo deste artigo é problematizar os argumentos de Shenkar (2001; 2008 e Luo e Shenkar (2007, segundo os quais a metáfora de "distância" não é apropriada para compreensão, descrição e análise do impacto da questão cultural em negócios internacionais. Propõe-se, aqui, sua substituição pela metáfora da "fricção cultural", que captura de forma mais legítima a essência das questões transculturais aplicadas aos fenômenos em negócios internacionais.

    Rita de Cássia Gabrielli Souza Lima

    Full Text Available Resumo O estudo teve por objetivo identificar os fundamentos que conduzem a tutoria acadêmica do Projeto Mais Médicos para o Brasil em Santa Catarina, a partir da unidade de análise “valores realizados”. Trata-se de um estudo exploratório e compreensivo realizado, em 2015, com tutores catarinenses, profissionais de referência descentralizados dos Ministérios da Educação e da Saúde e profissionais de referência técnica do Ministério da Educação. Utilizou-se como instrumentos de coleta de dados entrevista semiestruturada e grupo focal. Com base na categoria Provimento emergencial como força inovadora da operação cultural Programa Mais Médicos, a análise foi conduzida pelo método ético-político. Revelaram-se três fundamentos: apagar incêndios, qualificação do Projeto e perspectiva processual. Concluiu-se que a tutoria acadêmica das atividades produtivas de médicos do provimento emergencial não corresponde a um enfrentamento pedagógico isolado, pois é parte e consequência do desenvolvimento histórico da teoria e da prática. A atividade corresponde dialeticamente a movimentos de ruptura, resistência, emancipação e não prescinde da reflexão coletiva sobre os valores eleitos e realizados no agir deliberativo.

  1. Comunicação como Ciência Social (e mais

    Craig Calhoun

    Full Text Available A Comunicação é o campo mais importante para o estudo de muitas dimensões-chave de mudanças sociais. Esta é a premissa básica deste texto apresentado na conferência de abertura do congresso anual da International Communication Association, em 2011. Ele traz reflexões sobre uma série de questões de identidade, metodologias, fronteiras e caminhos para os estudos e práticas no campo. Fazendo um paralelo com outras disciplinas que passaram pelo mesmo processo, a conclusão é que o campo da Comunicação precisa mais preservar a riqueza de sua interdisciplinaridade do que buscar respostas em uma aparente e, às vezes, falsa autonomia científica.

    To determine the prevalence of dementia in Thai people with age 45 years and above. This project used a cross sectional research design to study the prevalence of dementia in Chiang Mai. Door-to-door technique was assigned in condition with multi-stage probability random sampling to obtain subjects representing the population of Chiang Mai between Oct 2004 and Sep 2005. The researchers collected the data from the subjects aged 45 years and above. All subjects were located from every Amphurs of Chiang Mai. They were first screened with Thai Mini Mental State Examination (TMSE) and Thai Beck Depression Inventory (BDI). The subjects whose TMSE was less than 24 were assessed and diagnosed by a neurologist. Subjects who were determined as having dementia might be laboratory analyzed and classified based on DSM-IV and NINDS-AIREN criteria. The authors enrolled 2,311 people and screened them with Batteries test. One thousand four hundred ninety two people qualified with 610 males and 882 females, whose mean age was 59.7 +/- 10.4 years. The authors found that among the 35 people with dementia, the mean age was 67.9 +/- 8.9 years (45-88 years). The prevalence of dementia among the study participants was 2.35%. In the present study, Alzheimer's disease was the most common type of dementia diagnosed (75.0%) and vascular dementia was the second most commonly diagnosed (12.5%). The prevalence of dementia in Chiang Mai was 2.35%, which does not differ from the previous study Alzheimer's disease was the most common type of dementia diagnosed.

    2006-01-01

    An emission inventory containing emissions from traffic and other sources was complied. Based on the analysis, Carbon Monoxide (CO) emissions from traffic play a very important role in CO levels in Chiang Mai area. Analysis showed that CO emissions from traffic during rush hours contributed approximately 90% of total CO emissions. Regional Atmospheric Modeling System (RAMS) was applied to simulate wind fields and temperatures in the Chiang Mai area, and eight cases were selected to study annual variations in wind fields and temperatures. Model results can reflect major features of wind fields and diurnal variations in temperatures. For evaluating the model performance, model results were compared with observed wind speed, wind direction and temperature, which were monitored at a meteorological tower. Comparison showed that model results are in good agreement with observations, and the model captured many of the observed features. HYbrid Particle And Concentration Transport model (HYPACT) was used to simulate CO concentration in the Chiang Mai area. Model results generally agree well with observed CO concentrations at the air quality monitoring stations, and can explain observed CO diurnal variations.

    An approximately multi-user OFDM transceiver was introduced to reduce the multi-access interference (MAI ) due to the carrier frequency offset (CFO) to a negligible amount via precoding by Tsai, Lin and Kuo. In this work, we investigate the performance of this precoded multi-user (PMU) OFDM system in a time-variant channel environment. We analyze and compare the MAI effect caused by time-variant channels in the PMU-OFDM and the OFDMA systems. Generally speaking, the MAI effect consists of two parts. The first part is due to the loss of orthogonality among subchannels for all users while the second part is due to the CFO effect caused by the Doppler shift. Simulation results show that, although OFDMA outperforms the PMU-OFDM transceiver in a fast time-variant environment without CFO, PMU-OFDM outperforms OFDMA in a slow time-variant channel via the use of M/2 symmetric or anti-symmetric codewords of M Hadamard-Walsh codes.

    Influenza is one of the most important leading causes of respiratory illness in the countries located in the tropical areas of South East Asia and Thailand. In this study the climate factors associated with influenza incidence in Chiang Mai Province, Northern Thailand, were investigated. Identification of factors responsible for influenza outbreaks and the mapping of potential risk areas in Chiang Mai are long overdue. This work examines the association between yearly climate patterns between 2001 and 2008 and influenza outbreaks in the Chiang Mai Province. The climatic factors included the amount of rainfall, percent of rainy days, relative humidity, maximum, minimum temperatures and temperature difference. The study develops a statistical analysis to quantitatively assess the relationship between climate and influenza outbreaks and then evaluate its suitability for predicting influenza outbreaks. A multiple linear regression technique was used to fit the statistical model. The Inverse Distance Weighted (IDW) interpolation and Geographic Information System (GIS) techniques were used in mapping the spatial diffusion of influenza risk zones. The results show that there is a significance correlation between influenza outbreaks and climate factors for the majority of the studied area. A statistical analysis was conducted to assess the validity of the model comparing model outputs and actual outbreaks.

    The present study was carried out to investigate the influence of lifestyle on bone mineral density (BMD) and bone turnover among young women in Chiang Mai, Thailand. A total of 177 young women affiliated with Chiang Mai University hospital were enrolled. Firstly, questionnaires about their lifestyle and the Osteoporosis Knowledge Test (OKT) were examined. The measurement of BMD was assessed by Quantitative Ultrasound (QUS). Secondly, based on the measurement of BMD, the subjects were divided into 2 groups, a Low BMD group (L group: less than YAM-1.0SD) and a Normal BMD group (N group: more than YAM-1.0SD). L group (n=23) and N group (n=23) were examined using Osteocalcine (OC), type 1 collagen cross-linked N-telopeptide (NTx) and undercarboxylated osteocalcin (ucOC) as bone turnover markers, and serum Ca, 1,25-(OH)2Vitamin D, Vitamin K1 and Vitamin K2 (MK-4) as bone turnover related factors. Based on the results, the percentage of Low BMD group was 23.2%. Concerning lifestyle and BMD, the BMD of the low cheese intake group was 99.7± 17.0 and the BMD of the high cheese intake one was 110.0± 23.3 (pChiang Mai, Thailand.

    Full Text Available Nas últimas décadas a temática em torno das questões que permeiam o meio ambiente se constituiu um dos assuntos relevantes dentro das muitas discussões no contexto das organizações. Nesse sentido, o objetivo dessa pesquisa se concentra em identificar as estratégias empresariais adotadas pelos gestores do setor de construção civil da cidade de Campina Grande, PB, em relação à qualidade ambiental e produção mais limpa. Para tanto, foi realizada uma pesquisa exploratória e descritiva, através de um questionário estruturado, junto a uma amostra de 41 empresas de um total de 67 organizações. O tipo de amostragem adotada foi a não probabilística e por acessibilidade. Os resultados evidenciam as estratégias mais usuais no sentido de obter a P+L, dentre elas, o treinamento de funcionários e a melhoria tecnológica. No entanto, boa parte dos respondentes não utiliza nenhuma técnica de P+L. Quanto ao tratamento dos resíduos da produção foi possível identificar que estão sendo destinados para o lixão da cidade. Apenas uma empresa utiliza tratamento dos entulhos em projetos paisagísticos, não obstante a estratégia mais relevante utilizada pelos gestores foi racionalização construtiva. Com tais resultados pode-se inferir e reconhecer que as estratégias adotadas pelos gestores do segmento estudado necessitam de uma redefinição, uma vez que o nível de competitividade de uma empresa depende de um conjunto de fatores, que se inter-relacionam dentro de questões econômicas, sociais e ambientais.

    Full Text Available Abstract Background Diarrhea is a major public health problem in Thailand. The Ministry of Public Health, Thailand, has been trying to monitor and control this disease for many years. The methodology and the results from this study could be useful for public health officers to develop a system to monitor and prevent diarrhea outbreaks. Methods The objective of this study was to analyse the epidemic outbreak patterns of diarrhea in Chiang Mai province, Northern Thailand, in terms of their geographical distributions and hotspot identification. The data of patients with diarrhea at village level and the 2001–2006 population censuses were collected to achieve the objective. Spatial analysis, using geographic information systems (GIS and other methods, was used to uncover the hidden phenomena from the data. In the data analysis section, spatial statistics such as quadrant analysis (QA, nearest neighbour analysis (NNA, and spatial autocorrelation analysis (SAA, were used to identify the spatial patterns of diarrhea in Chiang Mai province. In addition, local indicators of spatial association (LISA and kernel density (KD estimation were used to detect diarrhea hotspots using data at village level. Results The hotspot maps produced by the LISA and KD techniques showed spatial trend patterns of diarrhea diffusion. Villages in the middle and northern regions revealed higher incidences. Also, the spatial patterns of diarrhea during the years 2001 and 2006 were found to represent spatially clustered patterns, both at global and local scales. Conclusion Spatial analysis methods in GIS revealed the spatial patterns and hotspots of diarrhea in Chiang Mai province from the year 2001 to 2006. To implement specific and geographically appropriate public health risk-reduction programs, the use of such spatial analysis tools may become an integral component in the epidemiologic description, analysis, and risk assessment of diarrhea.

    Up to 65% of travelers to less developed countries report health problems while traveling. International travel is an increasing concern for health practitioners. To date, there have not been any published analyses of mortality amongst foreign nationals visiting Thailand. Our objectives are to examine the magnitude and characterize the deaths among foreign nationals in Chiang Mai, a popular tourist province in Thailand. The study commenced with a review of the Thai death registration. Death certificates were retrieved, reviewed, and classified by the causes of death. Basic statistics and proportionate mortality ratio (PMR) were used to describe the pattern of deaths. Standardized mortality ratio (SMR) was used to assess the excess mortality risk among foreign nationals. Between January 1, 2010 and May 31, 2011, there were 1,295 registered deaths in Chiang Mai City, of which 102 records (7.9%) were foreign nationals. Median age of decedents was 64 years (range 14-102 y). Female-to-male ratio was 1 : 5.4. The highest mortality was among Europeans (45.1%). Most of the deaths were natural causes (89.2%) including 36 cardiac diseases (PMR = 35.3) and 20 malignancy diseases (PMR = 19.6). Deaths due to external causes were low. The SMRs range between 0.15 and 0.30. Communicable diseases and injuries were not the leading causes of death among foreign nationals visiting Chiang Mai, Thailand. It is essential that travelers are aware of mortality risk associated with their underlying diseases and that they are properly prepared to handle them while traveling. © 2012 International Society of Travel Medicine.

    To identify the prevalence, clinical characteristics, disease severity, and correlations of major chronic respiratory diseases (CRDs) among the adult population living in Chiang Mai. A cross-sectional study was conducted with adults living in municipal areas of Chiang Mai. All clinical relevant data collected by face-to-face interview was confirmed by pulmonologists. The chest radiographic findings and post-bronchodilator spirometry were done in all subjects. The aeroallergen skin test and rhinoscopy were performed in all chronic rhinitis and asthma subjects. Five hundred seventy four subjects with mean age 52.9±10.0 years, 59.6% female, and 37.5% smokers were recruited. The prevalence of overall CRDs was 59.2%. Chronic rhinitis was the most prevalent chronic respiratory disease (n = 239, 41.6%), followed by asthma (n = 58, 10.1%), and chronic obstructive pulmonary disease (COPD) (n = 21, 3.7%). The most common abnormal pulmonary function test was restrictive lung disorders (n = 53, 9.6%). Asthma subjects were determined to be more allergic than chronic rhinitis subjects (58.1% vs. 39.9%, p-value = 0.033). Regarding the disease severity, 14.9% of chronic rhinitis and 10.3% of asthma subjects were classified as moderate to severe degree, whereas 81% of chronic obstructive pulmonary disease subjects were classified as moderate to very severe degrees. In asthma patients, there were positive association with chronic rhinitis (OR 3.9, 95% CI 2.1-7.0, p-value Chiang Mai population was significantly high with overlapped respiratory symptoms and varying disease severity. Additionally, chronic rhinitis had correlation with asthma but not with COPD.

    Full Text Available O desenvolvimento e o caráter oficial das avaliações internacionais e de padrões nacionais de rendimento escolar favorecem a coexistência de uma dupla definição institucional de sucesso escolar. A definição habitual leva em conta o ensino efetivamente ministrado, adapta-se ao nível dos alunos e apresenta uma fidedignidade duvidosa. A segunda é mais objetiva, mas privilegia o que pode ser medido por testes padronizados: o cognitivo mais do que o socioafetivo, as capacidades e conhecimentos mais que as competências e a relação com o saber. As duas avaliações entram em conflito. As regulações necessárias poderiam levar a uma aproximação do ideal: considerar, na avaliação do sucesso escolar, todos os componentes do currículo prescrito e tão-somente eles.Development and the official character of international assessments surveys and national standards of school performance favour the coexistence of a double institutional definition of success at school. The usual ones take into account the curriculum effectively taught, adapt itself to the levels of the pupils and present a rather doubtful reliability. The second one is more objective, but gives a too great weight to what can be measured through standardised tests: the cognitive more than the socio-emotional, the capacities and the knowledge more than the competencies and the relationship to knowledge. Both assessment and ordinary school evaluations are now in conflict. Necessary regulations could move them closer to the ideal, if they employed in order to consider the success at school, all the components of the formal curriculum and them only.

    Full text: The geothermal 'Felix-1 Mai-Oradea' deposit is situated in the western part of Romania and it is well known long years ago. The waters of this deposit are used in the medical treatments in the two resorts (Felix and 1 Mai) and for heating and swimming pools in Oradea town. The deposit depth (2500-3000 m) determines a high temperature (66-900 deg. C) of these waters also a mineral content of 200-1400 mg/l, the main components being Ca and Mg. First time, during some years, the thermal water was directly used in the central heating radiators from 'Nufarul' residential district. At present a heating switch installation is utilised. The high radium content of these thermal waters comparatively with Italian or Japanese thermal waters suggested us a study of radium deposition on the inner walls of the pipes also in the inner central heating radiators. Analysing these depositions using a high resolution Ge-Li detector, the radium-226 and small quantities of radium-224 and 223 isotopes were registered. Average radium-226 deposition was 1200 Bq/kg.

    This study was undertaken to determine the incidence of subsequent oophorectomy due to ovarian pathology or ovarian cancer in women with prior hysterectomy for benign gynecologic conditions at Chiang Mai University Hospital. Medical records of women who underwent hysterectomy for benign gynecologic diseases and pre-cancerous lesions between January 1, 2004 and December 31, 2013 at Chiang Mai University Hospital were retrospectively reviewed. The incidence and indications of oophorectomy following hysterectomy were analyzed. During the study period, 1,035 women had hysterectomy for benign gynecologic conditions. Of these, 590 women underwent hysterectomy with bilateral salpingo-oophorectomy and 445 hysterectomy with bilateral ovarian preservation or unilateral salpingo-oophorectomy. The median age was 47 years (range, 11-75 years). Ten women (2.45 %) had subsequent oophorectomy for benign ovarian cysts. No case of ovarian cancer was found. The mean time interval between hysterectomy and subsequent oophorectomy was 43.1 months (range, 2-97 months) and the mean follow-up time for this patient cohort was 51 months (range, 1.3-124.9 months). According to our hospital-based data, the incidence of subsequent oophorectomy in women with prior hysterectomy for benign gynecologic conditions is low and all present with benign conditions.

    Our study assessed the influence of HIV-related stigma on treatment adherence among people living with HIV in Chiang Mai, Thailand, and whether social support had a moderating effect on this relationship. We recruited 128 patients living with HIV from Sansai Hospital, a community hospital in Chiang Mai, Thailand, and collected data through structured interviews. All forms of HIV-related stigma considered in this study (personalized experience, disclosure, negative self-image, and public attitudes) were negatively correlated with adherence to anti-retroviral regimens. Multiple linear regression indicated that total HIV-related stigma was more predictive of treatment adherence than any individual stigma type, after adjusting for socio-demographic and health characteristics. Tests of interaction showed that social support did not appear to moderate the association between HIV stigma and treatment adherence. Our findings suggest that community and government efforts to improve public perceptions about people living with HIV might promote treatment adherence behaviors among HIV-positive patients.

    Poliovirus (PV) is typically transmitted by the fecal-oral route, which means that the risk of infection and virus distribution could be achieved by exposure to the virus contaminated in food and water. The aim of this study was to determine the occurrence of PV strains by detecting the virus in pediatric patients who admitted to the hospitals with diarrhea in Chiang Mai, Thailand during 2010-2015. By applying a reverse transcription-polymerase chain reaction and nucleotide sequencing analysis of 1,300 stool specimens collected from pediatric patients, PVs were detected at 0.61% (8 out of 1,300 specimens). Among eight PV positive samples, mixed infection with norovirus or human bocavirus was detected in one each out of eight cases. All PV strains detected in this study were characterized further by phylogenetic analysis of 343 bp of the 5' UTR and 315 bp of the partial VP1 sequences. The results revealed that eight PV strains detected in the present study two of each were PV1 and PV2, and four were PV3 serotypes of the Sabin vaccine strains. The data demonstrated the presence of PV1, PV2, and PV3 Sabin vaccine strains in children with acute gastroenteritis in Chiang Mai, Thailand. J. Med.

    To investigate the epidemiological situation of cercarial trematodes infection in freshwater snails from different water resources in Chiang Mai province, Thailand. The snail specimens were collected from 13 districts of Chiang Mai province during April 2008 to February 2012. The prevalence of cercarial infection in snails was investigated using the crushing method. The drawing was done with the help of a camera lucida for the morphological study. A total of 2 479 snail individuals were collected and classified into 7 families, 11 genera, and 14 species, Among them, 8 snails species were found to be infected with an overall prevalence of 17.27% (428/2 479), which infected with nine groups of cercariae; gymnocephalous cercaria, strigea cercaria, megalurous cercaria, monostome cercaria, parapleurolophocercous cercaria (Haplorchis cercaria), pleurolophocercous cercaria, furcocercous cercaria (Transversotrema cercaria), xiphidiocercaria, and virgulate cercaria. The parapleurolophocercous cercaria was found to be the dominant type among the cercarial infection in the snails (64.25%). The various species of snails found in the research location act as the intermediate hosts for the high prevalence of parasitic infection of many species of mammals. This work will provide new information on both the distribution and first intermediate host of trematodes.

    Trematode cercariae are commonly found in many freshwater gastropods. These cercariae can serve to identify the occurrence of such trematodes as Centrocestus formosanus, Haplorchis taichui, Haplorchoides sp, and Stellantchasmus falcatus, which are important parasites in Chiang Mai Province, Thailand. As the species of these cercariae cannot be identified accurately based on morphology, this study employed sequencing of a fragment of 28S ribosomal DNA and phylogenetic analysis to identify the trematode cercariae found in freshwater gastropods in Chiang Mai Province. Eight types of trematode cercariae were identified, namely, distome cercaria (grouped with Philophthalmus spp clade), echinostome cercaria (grouped with Echinostoma spp clade), furcocercous cercaria (grouped with Posthodiplostomum sp/Alaria taxideae/Hysteromorpha triloba clade), monostome cercaria (grouped with Catatropis indicus clade), parapleurolophocercous cercaria (grouped with Haplorchoides sp clade), pleurolophocercous cercaria (grouped with Centrocestusformosanus clade), transversotrema cercaria (grouped with Transversotrema spp clade), and xiphidiocercaria (grouped with Prosthodendrium spp clade). These results provide important information that can be used for identifying these parasites in epidemiological surveys.

    The occurrence of 37-collar spined echinostome metacercariae in freshwater snails was investigated in 6 districts of Chiang Mai Province, Thailand, from October 2011 to April 2012. A total of 2,914 snails that belong to 12 species were examined, and 7 snail species (Clea helena, Eyriesia eyriesi, Bithynia funiculata, Bithynia siamensis siamensis, Filopaludina doliaris, Filopaludina sumatrensis polygramma, and Filopaludina martensi martensi) were found infected with echinostome metacercariae. The prevalence of metacercariae was the highest in Filopaludina spp. (38.5-58.7%) followed by B. funiculata (44.0%), E. eyriesi (12.5%), B. siamensis siamensis (8.2%), and C. helena (5.1%). Metacercariae were experimentally fed to hamsters and domestic chicks, and adult flukes were recovered from both hosts at days 15 and 20 post-infection. The adult flukes were identified based on morphological features, morphometrics, host-parasite relationships, and geographical distribution. They were compatible to Echinostoma revolutum or Echinostoma jurini, with only minor differences. As the adults were recovered from both hamsters and chicks, our specimens were more compatible to E. revolutum rather than E. jurini (reported only from mammals). This is the first report for metacercariae of E. revolutum in the snail host, C. helena, and also confirmed that Filopaludina spp., E. eryresi, and Bithynia spp. act as the second intermediate hosts of E. revolutum under natural conditions, which are indigenously distributed in Chiang Mai province.

    Histoplasmosis is a systemic mycosis caused by inhaling spores of Histoplasma capsulatum, a dimorphic fungus. This fungus grows in soil contaminated with bat and avian excreta. Each year, patients with disseminated histoplasmosis have been diagnosed in Chiang Mai, northern Thailand. No published information is currently available on the environmental sources of this fungus in Chiang Mai or anywhere else in Thailand. The aim of this study was to detect H. capsulatum in soil samples contaminated with bat guano and avian droppings by nested PCR. Two hundred and sixty-five samples were collected from the following three sources: soil contaminated with bat guano, 88 samples; soil contaminated with bird droppings, 86 samples; and soil contaminated with chicken droppings, 91 samples. Genomic DNA was directly extracted from each sample, and H. capsulatum was detected by nested PCR using a primer set specific to a gene encoding 100-kDa-like protein (HcI, HcII and HcIII, HcIV). Histoplasma capsulatum was detected in seven of 88 soil samples contaminated with bat guano, one of 21 soil samples contaminated with pigeon droppings and 10 of 91 soil samples contaminated with chicken droppings. The results indicate the possibility of the association of bat guano and chicken droppings with H. capsulatum in this area of Thailand.

    Leptospirosis is an important zoonosis worldwide, nevertheless is often poor recognized in non tropical settings. In Thailand is becoming an emerging disease and Chiang Mai could become a popular spot to acquire the disease amongst travelers. We describe three cases of imported leptospirosis undifferentiated fever after travelling to Thailand during the summer of 2015 diagnosed at two Spanish hospitals. Our three patients probably acquired leptospirosis while swimming in freshwater around Chiang Mai, a Thailand's northern region with moderate incidence of leptopirosis. Travelers had normal white blood cell counts and low platelets, suggesting leptospirosis after ruling out other imported diseases such as malaria, dengue or typhoid. As recent findings point out, low platelets and normal white blood cell counts are clinical features that could help the clinician to suspect Leptospirosis infection. It should be always considered as a cause of fever, particularly if travelers come from a tropical country and have had contact with water or flooding, especially during rainy season.

    Full Text Available Considerando-se a evidente busca por alimentos de rápido e fácil preparo, as comunidades industrial e científica vêm investindo no desenvolvimento de novos produtos que, além de atenderem a essa demanda, possam oferecer benefícios à saúde do consumidor. Dentre os alimentos que não demandam muito tempo para o preparo no domicílio, o hambúrguer merece destaque, em função do seu elevado consumo. No entanto, em razão de conter gordura saturada e por ser submetido a processo de fritura, o consumo demasiado desse produto pode ser prejudicial à saúde humana, podendo causar doenças crônicas, entre as quais, a obesidade e a hipertensão. Estudos têm demonstrado a possibilidade de substituição de ingredientes na formulação de hambúrgueres, com a intenção de incorporar substâncias com propriedades funcionais; portanto, substâncias que possam contribuir para a saúde e o bem-estar dos consumidores. Nesse contexto, esta revisão aborda questões referentes ao hambúrguer, no sentido de conceituar o produto e, à luz da literatura, oferecer alternativas possíveis e que têm sido estudadas para tornar esse alimento mais saudável, com foco na substituição de gordura animal por fibras e na redução do teor de cloreto de sódio.

    Full Text Available O presente artigo almeja trazer à agenda das discussões sobre letramento na universidade a lacuna existente entre o ensino e a aprendizagem de gêneros escolares e de gêneros acadêmicos. Nossa inquietação é fruto de uma preocupação com os alunos ingressantes em instituições de ensino superior que não tiveram uma experiência escolar com vistas a uma prática social de letramento acadêmico. A partir do tema proposto, refletimos sobre como a teoria dos gêneros discursivos, bem como sua aplicabilidade, auxilia no desenvolvimento do letramento acadêmico desses alunos universitários. A proficiência, ou inserção, na esfera discursiva acadêmica está muito relacionada com a competência genérica que o aluno deve possuir para assegurar sua comunicação de forma a alcançar seu status de sujeito discursivo e transformador. Portanto, defendemos que, aliada à análise de gêneros discursivos acadêmicos, a metodologia de ensino de Português para Fins Acadêmicos, aos moldes da consagrada área de Inglês para Fins Acadêmicos (English for Academic Purposes, pode, em muito, contribuir para se criar uma tradição de letramento acadêmico que propicie ao estudante uma experiência mais significativa não somente na sua esfera acadêmica, mas também no domínio discursivo do qual ele venha a participar, uma vez egresso da universidade e apto para atuar na sua profissão.

    Full Text Available O artigo busca analisar desafios e impasses na implementação do Programa Mais Médicos, no município de Campos dos Goytacazes, no Estado do Rio de Janeiro. O estudo pretende ressaltar a guinada nas estratégias e ações da gestão pública municipal de saúde e, mais especificamente, traz como diferencial analítico a mudança de status orçamentário do município, decorrente da queda dos royalties do petróleo e as implicações na condução das políticas públicas. O argumento parte, de um lado, dos tempos de abundância e de escassez de recursos; e de outro, da empiria, relatada pela experiência profissional na Estratégia Saúde da Família. Os achados apontam que a chegada de médicos estrangeiros promoveu uma reestruturação positiva dos serviços de saúde. No entanto, pode-se perceber que o intercâmbio cultural, possibilitado pelo contato entre os profissionais brasileiros e cubanos no cotidiano de trabalho, propiciou novas práticas profissionais, valorizando as tecnologias relacionais.

    Full Text Available Abstract Background Bacterial leaf blight causes significant yield losses in rice crops throughout Asia and Africa. Although both the Asian and African strains of the pathogen, Xanthomonas oryzae pv. oryzae (Xoo, induce similar symptoms, they are nevertheless genetically different, with the African strains being more closely related to the Asian X. oryzae pv. oryzicola (Xoc. Results Changes in gene expression of the African Xoo strain MAI1 in the susceptible rice cultivar Nipponbare were profiled, using an SSH Xoo DNA microarray. Microarray hybridization was performed comparing bacteria recovered from plant tissues at 1, 3, and 6 days after inoculation (dai with bacteria grown in vitro. A total of 710 bacterial genes were found to be differentially expressed, with 407 up-regulated and 303 down-regulated. Expression profiling indicated that less than 20% of the 710 bacterial transcripts were induced in the first 24 h after inoculation, whereas 63% were differentially expressed at 6 dai. The 710 differentially expressed genes were one-end sequenced. 535 sequences were obtained from which 147 non-redundant sequences were identified. Differentially expressed genes were related to metabolism, secretion and transport, pathogen adherence to plant tissues, plant cell-wall degradation, IS elements, and virulence. In addition, various other genes encoding proteins with unknown function or showing no similarity to other proteins were also induced. The Xoo MAI1 non-redundant set of sequences was compared against several X. oryzae genomes, revealing a specific group of genes that was present only in MAI1. Numerous IS elements were also found to be differentially expressed. Quantitative real-time PCR confirmed 86% of the identified profile on a set of 14 genes selected according to the microarray analysis. Conclusions This is the first report to compare the expression of Xoo genes in planta across different time points during infection. This work shows that

    2013-04-01

    Full Text Available A consumer survey on dietary supplement consumption was carried out on 494 consumers aged 20 years and older in Chiang Mai province. The percentage of consumers who regularly consumed dietary supplements was 38.5%. Vitamins and minerals were the most consumed products, followed by functional drinks, functional foods, protein extracts, dietary fibre, cod liver oil, phytochemicals, algae products, fat absorbers, fish oils and bee products in that order. Females and participants who had recommended waistlines, had higher income, usually felt stressed or sick, and who preferred eating fruits/vegetables or routinely drank water tended to have a higher rate of consumption of dietary supplements. Participants gave priority over a product with guaranteed quality when they made decision to purchase dietary supplements, but their purchase was also influenced by the attractiveness of the product and advertisement for it.

  15. A Network of Kalman Filters for MAI and ISI Compensation in a Non-Gaussian Environment

    Full Text Available This paper develops a new multiuser detector based on a network of kalman filters (NKF dealing with multiple access-interference (MAI, intersymbol Interference (ISI, and an impulsive observation noise. The two proposed schemes are based on the modeling of the DS-CDMA system by a discrete-time linear system that has non-Gaussian state and measurement noises. By approximating the non-Gaussian densities of the noises by a weighted sum of Gaussian terms and under the common MMSE estimation criterion, we first derive an NKF detector. This version is further optimized by introducing a feedback exploiting the ISI interference structure. The resulting scheme is an NKF detector based on a likelihood ratio test (LRT. Monte-Carlo simulations have shown that the NKF and the NKF based on LRT detectors significantly improve the efficiency and the performance of the classical Kalman algorithm.

  17. The Chiang Mai Initiative and Its Multilateralization: Toward an Asian Monetary Fund?

    Directory of Open Access Journals (Sweden)

    Youngwon Cho

    2011-11-01

    Full Text Available As a regional self-help system of liquidity support established in the aftermath of the Asian crisis of 1997, the Chiang Mai Initiative (CMI and its recent multilateralization have been touted in some quarters as important achievements in a region where institutionalized financial cooperation had been sorely lacking, taking East Asia one step closer to the resuscitation of the still-born Asian Monetary Fund. Against such a sanguine assessment, I argue that the significance of the CMI, even after its multilateralization, is largely limited to symbolism and its practical implications are inconsequential. Despite the progress associated with CMI multilateralization, the underlying political dynamics in the region render East Asia fundamentally incapable of producing a coherent regional solution to the recurring problem of global financial instability.

  18. Culture and subjectivity – areas of continuity and rupture: the history of Mukhtar Mai

    Directory of Open Access Journals (Sweden)

    Jennifer Perroni

    2009-07-01

    Full Text Available In 2002 a Pakistani woman named Mukhtar Mai was sentenced to collective rape for a crime committed by her brother. Unfortunately, situations like these cannot be considered rare in Pakistan, where rape as a way of resolving conflicts between families is a common practice. Consequently, the most remarkable aspect of this story may have been the reaction of this woman, who instead of resigning herself to silence or committing suicide, which is common in these cases, initiated a campaign of protest and struggle in favor of women’s rights in her country. Through this story we can perceive how tradition and culture permeate the actions and representations of a people in which the femail body still represents an object that can be used for the honor or shame of the clan. But this system of values also makes possible the rise of indivuduals who are able to break with a pattern of subordination.

    Autologous chondrocyte implantation (ACI) has become one of the standard procedures for articular cartilage defect treatment. This technique provides a promising result. However the procedural process requires an approach of several steps from multidisciplinary teams. Although the success of this procedure has been reported from Srinakharinvirot University since 2007, the application of ACI is still limited in Thailand due to the complexity of processes and stringent quality control. This report is to present the first case of the cartilage defect treatment using the first generation-ACI under Chiang Mai University's (CMU) own facility and Ethics Committee. This paper also reviews the process of biotechnology procedures, patient selection, surgical, and rehabilitation techniques. The success of the first case is an important milestone for the further development of the CMU Human Translational Research Laboratory in near future.

    Electrocardiography is one of the most important non-invasive diagnostic tools for diagnosing coronary heart disease. The electrocardiography information system in Maharaj Nakorn Chiang Mai Hospital required a massive manual labor effort. In this article, we propose an approach toward the integration of heterogeneous electrocardiography data and the implementation of an integrated electrocardiography information system into the existing Hospital Information System. The system integrates different electrocardiography formats into a consistent electrocardiography rendering by using Java software. The interface acts as middleware to seamlessly integrate different electrocardiography formats. Instead of using a common electrocardiography protocol, we applied a central format based on Java classes for mapping different electrocardiography formats which contains a specific parser for each electrocardiography format to acquire the same information. Our observations showed that the new system improved the effectiveness of data management, work flow, and data quality; increased the availability of information; and finally improved quality of care. © The Author(s) 2014.

    Objectives. We examined correlates of incarceration among young methamphetamine users in Chiang Mai, Thailand in 2005 to 2006. Methods. We conducted a cross-sectional study among 1189 young methamphetamine users. Participants were surveyed about their recent drug use, sexual behaviors, and incarceration. Biological samples were obtained to test for sexually transmitted and viral infections. Results. Twenty-two percent of participants reported ever having been incarcerated. In multivariate analysis, risk behaviors including frequent public drunkenness, starting to use illicit drugs at an early age, involvement in the drug economy, tattooing, injecting drugs, and unprotected sex were correlated with a history of incarceration. HIV, HCV, and herpes simplex virus type 2 (HSV-2) infection were also correlated with incarceration. Conclusions. Incarcerated methamphetamine users are engaging in behaviors and being exposed to environments that put them at increased risk of infection and harmful practices. Alternatives to incarceration need to be explored for youths. PMID:18923109

    The Plasma and Beam Physics Research Facility at Chiang Mai University has established a THz facility to focus on the study of ultra-short electron pulses. Short electron bunches can be generated from a system that consists of a radio-frequency (RF) gun with a thermionic cathode, an alpha magnet as a magnetic bunch compressor, and a linear accelerator as a post-acceleration section. The alpha magnet is a conventional and simple instrument for low-energy electron bunch compression. With the alpha magnet constructed in-house, several hundred femtosecond electron bunches for THz radiation production can be generated from the thermionic RF gun. The construction and performance of the alpha magnet, as well as some experimental results, are presented in this paper.

    2011-01-01

    A femtosecond electron source has been developed at the Plasma and Beam Physics Research Facility (PBP), Chiang Mai University (CMU), Thailand. Ultra-short electron bunches can be produced with a bunch compression system consisting of a thermionic cathode RF-gun, an alpha-magnet as a magnetic bunch compressor, and a linear accelerator as a post acceleration section. To obtain effective bunch compression, it is crucial to provide a proper longitudinal phase-space distribution at the gun exit matched to the subsequent beam transport system. Via beam dynamics calculations and experiments, we investigate the bunch compression efficiency for various RF-gun fields. The particle distribution at the RF-gun exit will be tracked numerically through the alpha-magnet and beam transport. Details of the study and results leading to an optimum condition for our system will be presented.

    The regional atmospheric modeling system (RAMS) was applied to Chiang Mai province, a mountainous area in Thailand, to study terrain-induced mesoscale circulations. Eight cases in wet and dry seasons under different weather conditions were analyzed to show thermal and dynamic impacts on local circulations. This is the first study of RAMS in Thailand especially investigating the effect of mountainous area on the simulated meteorological data. Analysis of model results indicates that the model can reproduce major features of local circulation and diurnal variations in temperatures. For evaluating the model performance, model results were compared with observed wind speed, wind direction, and temperature monitored at a meteorological tower. Comparison shows that the modeled values are generally in good agreement with observations and that the model captured many of the observed features.

    To contribute to the development of nuclear science and technology in Thailand, a comprehensive ion beam analysis center unique in the ASEAN region has recently been established at Chiang Mai University, Thailand. The center is equipped with a 1.7-MV Tandetron tandem accelerator with an ion beam analysis beam line. The beam line is currently capable of performing ion beam analysis techniques such as Rutherford Backscattering Spectrometry (RBS), RBS/channeling, Elastic BackScattering (EBS), Particle Induced X-ray Emission (PIXE) and Ionoluminescence (IL) with assistance of commercial and in-house-developed softwares. Micro ion beam for MeV-ion mapping using programmable aperture or capillary focusing techniques is being developed. Ion beam analysis experiments and applications have been vigorously developed, especially for novel materials analysis focused on archeological, gemological and biological materials besides other conventional materials.

    This study investigated the short-term effects of temperature on out-patient visits and hospital admissions in Chiang Mai, Thailand. While mortality outcomes in the literature have been reported, there is less evidence of morbidity effects with very few studies conducted in developing countries with subtropical or tropical climate. Time-series regression analysis was employed using generalized negative binomial regression to model the short-term relationships between temperature and morbidity after controlling for seasonal patterns and other potential confounders. Lag effects up to 13 days and effect modification by age (0-14 years, 15-64 years, ≥65 years) were examined. Temperature effects with wide confidence intervals were found, with an increase in diabetic visits of 26.3% (95% CI: 7.1%-49.0%), and circulatory visits of 19.2% (95% CI: 7.0%-32.8%) per 1 °C increase in temperature above an identified threshold of 29 °C. Additionally, there was a rise of both visits (3.7% increase, 95% CI: 1.5%-5.9%) and admissions (5.8% increase, 95% CI: 2.3%-9.3%) due to intestinal infectious disease in association with each 1 °C increase across the whole temperature range. The effects of temperature were stronger in the elderly though not statistically significant. Daily morbidity in Chiang Mai was positively associated with temperature with a lag effect of up to 2 weeks, which was longer than lag effects previously reported. Public health preparedness and interventions should be considered to minimise possible increased hospital visits and admissions during hot weather. Copyright © 2011 Elsevier B.V.

    Objectives: This study was conducted to determine incidence trends of female breast cancer according to age groups and to predict future change in Chiang Mai women through 2028. Method: Data were collected from all hospitals in Chiang Mai in northern Thailand, from 1989 through 2013, and used to investigate effects of age, year of diagnosis (period) and year of birth (cohort) on female breast cancer incidences using an age-period-cohort model. This model features geometric cut trends to predict change by young (<40 years), middle-aged (40-59) and elderly (≥60) age groups. Result: Of 5, 417 female breast cancer patients with a median age of 50 years (interquartile range: 43 to 59 years), 15%, 61% and 24% were young, middle-aged and elderly, respectively. Seventy nine percent of cancer cases in this study were detected at advanced stage. The trend in stage classification showed an increase in percentage of early stage and a decrease in metastatic cancers. Linear trends for cohort and period were not found in young females but were observed in middle-aged and elderly groups. Age-standardized rates (ASR) can be expected to remain stable around 6.8 per 100,000 women-years in young females. In the other age groups, the ASR trends were calculated to increase and reach peaks in 2024 of 120.2 and 138.2 per 100,000 women-years, respectively. Conclusion: Cohort effects or generation-specific effects, such as life style factors and the year of diagnosis (period) might have impacted on increased incidence in women aged over 40 years but not those under 40 years. A budget should be provided for treatment facilities and strategies to detect early stage cancers. The cost effectiveness of screening measures i.e. mammographic screening may need to be reconsidered for women age over 40 years. PMID:28612595

    Full Text Available O artigo explora os processos de formação do Estado e as políticas culturais governamentais em Córdoba (Argentina durante a primeira década do século XXI. A partir da análise das cerimônias que marcam a inauguração de mostras de arte, ou vernissages, são discutidas as dimensões performativas das práticas estatais e descritas performances que, em nome da cultura, “fazem Estado” através de formas altamente estetizadas que apelam para a captação sensorial. Nessas performances, que envolvem os sujeitos a partir da estimulação poética de seus sentidos, o Estado se materializa duas vezes. A “magia do Estado” se faz quando acrescenta e estatiza as relações de interdependência entre diferentes agentes e quando materializa uma imagem atraente encarregada de reforçar a distinção como recurso para a produção de hegemonia.The present article explores processes of State formation and government cultural policies in Córdoba (Argentina during the first half of the 21st century. Analyzing the cerimonies that attend the inauguration of art exhibits - vernissages - we discuss the performative dimensions of State practices that, in the name of culture, “make the State” through highly esteticized forms which appeal to the senses. In these performances, the State is materialized in two ways. The “magic of the State” occurs when interdependent relationships between agents appears and is institutionalized and also when na attractive image materializes that destined to reinforce this distinction as a resource for the production of hegemony.

    Full Text Available As organizações da sociedade civil têm um papel didático na instrução de seus membros sobre política que extrapola as questões imediatas de interesse dessas organizações? A maior parte da literatura, especialmente aquela sobre o orçamento participativo (OP do Partido dos Trabalhadores do Brasil, sustenta que o OP é uma estrutura de oportunidade para que os indivíduos se reúnam e debatam não só problemas locais, mas também discutam política num sentido mais amplo. A mesma lógica se aplica a outras formas de militância, tais como participação em sindicatos, partidos políticos, associações de bairro e grupos de igreja. Este trabalho procura testar, usando dados longitudinais de opinião pública de eleitores brasileiros coletados nas eleições de 2002, se os militantes da sociedade civil organizada são, de fato, mais bem informados sobre política, especificamente, sobre questões eleitorais. Além disso, este trabalho testa também se potenciais diferenças de informação causadas por gênero, raça e classe são atenuadas pela participação em organizações da sociedade civil.Do civil society organizations have a didactic role in instructing its members about politics that extrapolates the immediate issues of interest of that organization? Most of the literature, especially that on the role of the participatory budgeting process of the Workers´ Party in Brazil, claims that such meetings are an opportunity structure for individuals to come together and not only debate their local problems, but also discuss politics more broadly. The same logic applies to other forms of activism, such as participation in Labor Unions, political parties, neighborhood associations and even church groups. This paper attempts to test, using a unique public opinion panel dataset of Brazilian voters collected in the 2002 elections, if activists are, in fact, better informed about politics, specifically, about campaign issues.

  19. Digging for Lost Rivers in Thailand: Locating and Dating Paleochannels in the Chiang Mai Intermontane Basin

    Science.gov (United States)

    Teo, Elisha A.; Ziegler, Alan D.; Wasson, Robert J.; Morthekai, Paulramasamy

    2017-04-01

    The drainage of the Chiang Mai basin has a dynamic but largely forgotten history. In the late 1980s, an ancient lost city was excavated near the Ping River in Chiang Mai, Thailand. Archaeologists had unearthed Wiang Kum Kam, the former royal capital of the Lanna Civilisation founded in 1286 CE. Former investigations revealed that flood sediments buried the capital and remnants of an abandoned river channel were discovered beneath the surface. This concurs with historical descriptions of the Ping River being on the eastern bank of the capital, despite being presently located on the western bank. The paleochannel drained 500 years ago after diverting west of the ancient city. This switch, an avulsion, coincided with a large flood, which could have triggered and/or caused the avulsion. Local oral histories also recount other Ping avulsions across the basin, but these were not documented. Some of these paleochannels residually remain as unusually sinuous irrigation canals, with historically suggestive names such as the Old Ping and the Small Ping Rivers. Here, the geomorphological evolution of the Ping River is investigated, as a future avulsion in this extensively populated area would be catastrophic. Evidence shows that the drainage of the Chiang Mai basin evolved from a braided system, to an avulsing anastomosing system, to a primarily single channel system. Two-dimensional electrical resistivity tomography and augering detected a large continuous body of fluvial sand 4 m below the surface, across the 10 km distance between the Ping and Kuang Rivers. This sand continues to the depth of at least 30 m and is typical of a braided system. Further augering along paleochannels revealed buried levees that protrude from the braided river deposits to near the surface, separated by fine floodplain sediments. This may have formed as the braided system evolved into an anastomosing system, where distinct channels stabilised and floodplain deposits could develop between channels

    Objectives To examine the damage location distribution of five main body region injuries of maximum abbreviated injury score (MAIS) 3–6 injured occupants for nearside struck vehicle in front-to-side impact crashes. Design and setting MAIS 3–6 injured occupants information was extracted from the US-National Automotive Sampling System/Crashworthiness Data System in the year 2007; it included the head/face/neck, chest, pelvis, upper extremity and lower extremity. Struck vehicle collision damage was classified in a three-dimensional system according to the J224 Collision Deformation Classification of SAE Surface Vehicle Standard. Participants Nearside occupants seated directly adjacent to the struck side of the vehicle with MAIS 3–6 injured, in light truck vehicles–passenger cars (LTV–PC) side impact crashes. Outcome measures Distribution of MAIS 3–6 injured occupants by body regions and specific location of damage (lateral direction, horizontal direction and vertical direction) were examined. Injury risk ratio was also assessed. Results The lateral crush zone contributed to MAIS 3–6 injured occupants (n=705) and 50th centile injury risks when extended into zone 3. When the crush extended to zone 4, the injury risk ratio of MAIS 3–6 injured occupants approached 81%. The horizontal crush zones contributing to the highest injury risk ratio of MAIS 3–6 occupants were zones ‘D’ and ‘Y’, and the injury risk ratios were 25.4% and 36.9%, respectively. In contrast, the lowest injury risk ratio was 5.67% caused by zone ‘B’. The vertical crush zone which contributed to the highest injury risk ratio of MAIS 3–6 occupants was zone ‘E’, whose injury risk ratio was 58%. In contrast, the lowest injury risk ratio was 0.14% caused by zone ‘G+M’. Conclusions The highest injury risk ratio of MAIS 3–6 injured occupants caused by crush intrusion between 40 and 60 cm in LTV–PC nearside impact collisions and the damage region of the struck

Distribution of MAIS 3-6 injured occupants by body regions and specific location of damage (lateral direction, horizontal direction and vertical direction) were examined. Injury risk ratio was also assessed. The lateral crush zone contributed to MAIS 3-6 injured occupants (n=705) and 50th centile injury risks when extended into zone 3. When the crush extended to zone 4, the injury risk ratio of MAIS 3-6 injured occupants approached 81%. The horizontal crush zones contributing to the highest injury risk ratio of MAIS 3-6 occupants were zones 'D' and 'Y', and the injury risk ratios were 25.4% and 36.9%, respectively. In contrast, the lowest injury risk ratio was 5.67% caused by zone 'B'. The vertical crush zone which contributed to the highest injury risk ratio of MAIS 3-6 occupants was zone 'E', whose injury risk ratio was 58%. In contrast, the lowest injury risk ratio was 0.14% caused by zone 'G+M'. The highest injury risk ratio of MAIS 3-6 injured occupants caused by crush intrusion between 40 and 60 cm in LTV-PC nearside impact collisions and the damage region of the struck vehicle was in the zones 'E' and 'Y'.

    This preliminary study was conducted to address the issue of academic planning skills among new university student. Due to lack of proper measurement mechanism for awareness and readiness among students, this study proposes Metacognitive Awareness Inventory (MAI) to assess the connection between student self-efficacy and college readiness. Qualitative and quantitative approach were used by provide an online self-assessment for new student of Faculty of Computer Systems & Software Engineering (FSKKP) and analyse the data respectively. The possible relationships between MAI and College Readiness Item (CRI) in self-assessment has been evaluated. The sample size of 368 respondents from UMP are responding to the online self-assessment. The initial finding shows most student (71%) of the respondent lack of skills in planning. We manage to use Pearson Product-moment correlation coefficient to find the significant relationship between MAI and CRI. Thus, we found that College Readiness provide sufficient evidence that there is a significant correlation with most of MAI items. The findings also indicated not much difference was found between gender in terms of self-efficacy level. This paper suggests the MAI and CRI is a reliable and valid scale to respond the planning skills issues among new university students.

    Full Text Available This study was aimed to investigate the effect of heat treatment and shelf life on chilling injury of mango cv.Nam Dok Mai.The heat treatment of mango pulp during storage were determined by hot air oven set at 34 and 38°C for three intervals, as 24, 48, and 72 hours, then they were subsequently stored at 5°C for 10, 20, and 30 days to determine the appropriate shelf life. The findings showed that the symptom of mango fruit after chilling injury appeared within the 30th day of storage at 5°C. Several symptoms of mango fruit after chilling injury treatment were observed, i.e., pitting, browning on the skin, water soaking, and rapid rotting of the fruits that resulted in shorter shelf life. It was found that chilling injury mangoes had lower level of total soluble solid, higher disease incidence, and lower quality of fruit when compared with normal ripe-mango fruits at 25°C. Mango fruits treated at 34°C for either 24 or 48 hours, and at 38°C for 24 hours prior to cold storage at 5°C for 10 and 20 days showed a significant reduction in the chilling injury (CI index when compared to that of non-heated fruits. On the other hand, the heat treatment did not affect fruit weight loss, firmness, color changes, and water soaking at 5°C.

    Developing high technologies but in economic manners is necessary and also feasible for developing countries. At Chiang Mai University, Thailand, we have developed MeV-ion microbeam technology based on a 1.7-MV Tandetron tandem accelerator with our limited resources in a cost-effective manner. Instead of using expensive and technically complex electrostatic or magnetic quadrupole focusing lens systems, we have developed cheap MeV-ion microbeams using programmed L-shaped blade aperture and capillary techniques for MeV ion beam lithography or writing and mapping. The programmed L-shaped blade micro-aperture system consists of a pair of L-shaped movable aperture pieces which are controlled by computer to cut off the ion beam for controlling the beam size down to the micrometer order. The capillary technique utilizes our home-fabricated tapered glass capillaries to realize microbeams. Either system can be installed inside the endstation of the MeV ion beam line of the accelerator. Both systems have been applied to MeV-ion beam lithography or writing of micro-patterns for microfluidics applications to fabricate lab-on-chip devices. The capillary technique is being developed for MeV-ion beam mapping of biological samples. The paper reports details of the techniques and introduces some applications.

    This study aimed to investigate the morphology and reconstruct the phylogenetic relationships of Centrocestus formosanus originating from 5 species of freshwater fish, i.e., Esomus metallicus, Puntius brevis, Anabas testudineus, Parambassis siamensis , and Carassius auratus , in Chiang Mai province, Thailand. Sequence-related amplified polymorphism (SRAP) and phylogeny based on internal transcribed spacer 2 (ITS2) and mitochondrial cytochrome c oxidase subunit 1 (CO1) were performed. The results showed similar morphologies of adult C. formosanus from day 5 after infection in chicks. C. formosanus originated from 4 species of freshwater fish had the same number of circumoral spines on the oral sucker, except for those from C. auratus which revealed 34 circumoral spines. The phylogenetic tree obtained from SRAP profile and the combination of ITS2 and CO1 sequence showed similar results that were correlated with the number of circumoral spines in adult worms. Genetic variability of C. formosanus also occurred in different species of freshwater fish hosts. However, more details of adult worm morphologies and more sensitive genetic markers are needed to confirm the species validity of C. formosanus with 34 circumoral spines originating from C. auratus in the future.

    Management of patients with severe hypertension without progressive target organ damage remains controversial. Some guidelines mentioned oral anti-hypertensive medication as a treatment to reduce blood pressure in the emergency department, while others recommended against such treatment. To review the management ofpatients with severe hypertension without progressive target organ damage in the emergency department, Maharaj Nakorn Chiang Mai hospital. In a retrospective descriptive analysis study, medical records ofadult patients diagnosed with severe hypertension without progressive target organ damage between January 2011 and December 2012 were reviewed. Patient demographics, data on management including investigation sent and treatment given were collected. Statistical analysis was done by using descriptive statistics and Kruskal-Wallis one-way analysis of variance test. One hundred fifty one medical records were reviewed. Four oral anti-hypertensive medication were used to reduce blood pressure, Amlodipine, Captopril, Hydralazine, and Nifedipine. There were no significant diference between each medication in terms of their effect on bloodpressure reduction (p = 0.513). No side effect or other complications from the use of oral anti-hypertensive medication were recorded The choice of medication used for the treatment of hypertensive urgency ranged from Amlodipine, Captopril, Hydralazine, and Nifedipine, which varied in dosage. However their efficacies were the same when compared with each other and none produced any notable side effects.

    Open burnings (forest fires, agricultural, and garbage burnings) are the major sources of air pollution in Chiang Mai, Thailand. A time series prospective study was conducted in which 3025 participants were interviewed for 19 acute symptoms with the daily records of ambient air pollutants: particulate matter less than 10 microm in size (PM10), carbon monoxide (CO), nitrogen dioxide (NO2), sulfur dioxide (SO2), and ozone (O3). PM10 was positively associated with blurred vision with an adjusted odds ratio (OR) of 1.009. CO was positively associated with lower lung and heart symptoms with adjusted ORs of 1.137 and 1.117. NO2 was positively associated with nosebleed, larynx symptoms, dry cough, lower lung symptoms, heart symptoms, and eye irritation with the range of adjusted ORs (ROAORs) of 1.024 to 1.229. SO2 was positively associated with swelling feet, skin symptoms, eye irritation, red eyes, and blurred vision with ROAORs of 1.205 to 2.948. Conversely, O3 was negatively related to running nose, burning nose, dry cough, body rash, red eyes, and blurred vision with ROAORs of 0.891 to 0.979.

    This article compares coital experience of Chiang Mai 17–20-year-olds who were: (1) out-of-school; (2) studying at vocational schools; and (3) studying at general schools or university. Four-fifths, two-thirds and one-third, respectively, of males in these groups had had intercourse, compared to 53, 62 and 15 per cent of females. The gender difference for general school/university students, but not vocational school students, probably reflects HIV/AIDS refocusing male sexual initiation away from commercial sex workers. Vocational school females may have been disproportionately affected. Loss of virginity was associated, for both sexes, with social-educational background and lifestyle, and was less likely in certain minority ethnic groups. Among males, it was also associated with age and parental marital dissolution, and among females, with independent living and parental disharmony. Within social-educational groups, lifestyle variables dominated, but among general school/university students, parental marital dissolution (for males) and disharmony (for females) were also important, and Chinese ethnicity deterred male sexual experimentation.

    Drawing upon quantitative and qualitative data we explore perspectives on and experiences of sexual lifestyles and relationships among more than 1,750 adolescents aged 17-20 years who reside in urban Chiang Mai, Thailand. We focus on respondents’ representations and understandings of their sexual/gender identities derived mainly from in-depth interviews and focus group discussions, supplemented with observations and field notes. Our results show that while many young Thais described themselves as heterosexual males or females others described themselves as gay, kathoey, tom, dii, bisexual or something else. Some were still questioning their own identities. The terms gay, kathoey, tom and dii are commonly used by these Thais to describe a range of sexual/gender identities relating to persons who are sexually or romantically attracted to the same biological sex. We use case studies to illustrate the distinctive characterizations, sexual lifestyles and relationships of each of these identities. We conclude that the sexual lifestyles encountered among Northern Thai non-heterosexual adolescents could lead to negative health consequences and indicated a need for improved relationship education, counselling and sensitive sexual health services.

    A comprehensive ion beam analysis centre unique in the ASEAN (Association of Southeast Asian Nations) region has been established at Chiang Mai University, Thailand. The centre is equipped with a 1.7 MV Tandetron tandem accelerator and a 300 kV medium energy ion beam accelerator for ion beam analysis. The Tandetron accelerator employs two ion sources, a duoplasmatron ion source and a sputter ion source, capable of producing ion beams of both light species (hydrogen and helium) and heavy species. The beamline is currently able to perform ion beam analysis techniques, such as Rutherford backscattering spectrometry (RBS), RBS/channelling, elastic backscattering (EBS), particle induced x ray emission (PIXE) and ionoluminescence (IL) with the assistance of commercial and self-developed software. The medium energy ion accelerator features an ns pulsed beam so that time of flight (ToF) RBS analysis using medium energy ion beams is available for detailed analysis of materials. Ion beam analysis experiments and applications have been vigorously developed for the real time characterization of various materials. Examples are presented and qualities of the ion beam analysis techniques are discussed. (author)

    Soil-gas radon concentration anomaly map was constructed to help detect an unknown subsurface fault location in San Sai District, Chiang Mai Province, Northern Thailand where a 5.1-magnitude earthquake took place in December 2006. It was suspected that this earthquake may have been associated with an unrecognized active fault in the area. In this study, soil-gas samples were collected from eighty-four measuring stations covering an area of approximately 50 km2. Radon in soil-gas samples was quantified using Scintrex Radon Detector, RDA-200. The samplings were conducted twice: during December 2014-January 2015 and March 2015-April 2015. The soil-gas radon map obtained from this study reveals linear NNW-SSE trend of high concentration. This anomaly corresponds to the direction of the prospective fault system interpreted from satellite images. The findings from this study support the existence of this unknown fault system. However a more detailed investigation should be conducted in order to confirm its geometry, orientation and lateral extent.

Sin embargo, hoy, si se considera la evolución de varios indicadores económicos y sociales de las diferentes áreas metropolitanas brasileñas en relación con el resto del país, (particularmente las zonas del interior que empiezan a experimentar la modernización, se podría llamar al proceso por el que pasan como involución metropolitana. Esta sería una consecuencia del resultado de la difusión en el territorio de aquello que se ha llamado medio científico–técnico, que es consecuencia de la difusión a escala mundial de las variables que caracterizan el presente periodo histórico. De acuerdo con lo anterior, las transformaciones recientemente ocurridas en la superficie de la tierra en un gran número de lugares, estarían marcadas por las contribuciones de la ciencia y la tecnología, de tal manera que los lugares se caracterizan en función de las diferencias de información que hay entre ellos. Se estaría produciendo, por lo tanto, un cambio fundamental en el medio geográfico, dejando de ser simplemente un medio natural o un medio técnico para transformarse en un medio técnico–científico internacional. Sobre la base de lo anterior la naturaleza de la vida contribuye a la formación de nuevas relaciones sociales que traen consecuencias al proceso de urbanización. En este trabajo se presenta el caso brasileño donde se puede apuntar como resultado de la involución metropolitana antes mencionada, un fenómeno paralelo e interdependiente que es un crecimiento de la región más importante que el de la metrópoli y de una tendencia a tener una calidad de vida mejor en el interior.

CONCLUSÃO: Para os idosos mais ativos, a redução na autoeficácia pode sugerir que cair desencadeia alguns comportamentos protetores, tais como lentidão na marcha e sintomas depressivos, mas a relação causal entre quedas e esses desfechos devem ser mais investigados. Esses dados enfatizam que os fisioterapeutas devem ficar atentos ao fato de que há diferenças nos fatores relacionados a quedas, dependendo do nível de atividade física dos pacientes idosos, e isso deve ser considerado ao se planejarem intervenções para tal população.

Trata-se de um estudo exploratório transversal realizado entre janeiro e março de 2016, por meio de questionário autoaplicável, contendo uma lista de 49 procedimentos, atividades e ações realizadas na APS. Participaram do estudo 1.241 médicos, a maioria do sexo feminino, entre 40-49 anos de idade, de nacionalidade cubana. Os médicos realizaram uma média de 22,8 ± 8,2 procedimentos, porém, relataram saber fazer um número maior. Fatores associados à realização de maior número de procedimentos foram sexo masculino, menor tempo de graduação, dois anos ou menos de atuação na UBS, atuar na região geográfica Norte ou Sul, em municípios de pequeno porte e mais distantes da sede da região de saúde. O principal motivo para não realizar os procedimentos e atividades que relataram saber fazer foi a falta de materiais e a infraestrutura inadequada. Os resultados revelam que o escopo de prática dos médicos do PMM está abaixo de suas capacidades, sendo necessárias intervenções para o ampliar.

O segundo diz respeito a este objeto hipotético que seria 'o trabalho que não é mais o trabalho'. Se este último designa o trabalho não mercantil e o trabalho informal por distinção (ou oposição ao trabalho mercantil, então o 'trabalho que não é mais o trabalho' continua sendo, na realidade, um trabalho. Todavia, ele é diferente do trabalho mercantil, que, de acordo com uma postura etnocêntrica, supostamente constitui uma referência para a avaliação da natureza das atividades humanas. Mas, qualquer que seja o modo de trabalho dominante num coletivo de vida, uma análise da norma na atividade dita informal, do duplo ponto de vista do conceito e da experiência, permite sugerir que uma atividade humana socializada não pode ser verdadeiramente informal. Algumas balizas metodológicas permitem tentar compreender as atividades supostamente informais, chamando a atenção para os princípios epistemológicos da ergonomia e da ergologia.How to recognize work when is not work anymore? This question entails two aspects: the first one is a question of method (how to recognize work?. The second one is about this hypothetical subject that is 'work when it is not work anymore?'. If we talk about non-profit and informal work opposed to 'standard' work, then 'work that is not work anymore' is actually still work. Although, from an ethnocentric point of view, it is different from 'standard' work, which is supposed to be a reference in order to identify the nature of human activities. However, when analyzing the norm in informal activities, whatever the prevailing kind of work in a society, and from a conceptual as well as from a practical point of view, allows us to consider that a social human activity cannot be informal.

    Cryptococcal meningitis (CM) is a common central nervous system infection in HIV-infected patients. This study aimed to determine treatment outcomes among HIV-infected patients who had cryptococcal meningitis and to determine predictors of death. We conducted a retrospective cohort study among HIV-infected patients receiving care at Chiang Mai University Hospital from January 1, 2005 to December 31, 2010. We studied 79 patients; 45 (57.0%) were male and the mean age was 35.1 +/- 7.2 years. Eleven patients (13.9%) had previous opportunistic infection. The most common presenting symptoms were headache (63 patients, 79.8%), fever (49 patients, 62.0%), and altered consciousness (21 patients, 26.6%). The median CD4+ cell count was 20 cells/mm3 [Interquartile range (IQR) 10, 53]. The in-hospital, 90-day, and 1-year mortality rates were 24.1%, 32.4%, and 52.2%, respectively. The CM attributable in-hospital, 90-day and 1-year mortality rates were 13.9%, 20.3%, and 23.2%, respectively. Predictors associated with a 1-year mortality were a high cerebrospinal (CSF) cryptococcal antigen titer (> 1:10,000) [Odds Ratio (OR) =7.08, 95% confidence interval (CI): 1.62-31.00, p = 0.009], and altered consciousness at presentation (OR = 5.27; 95% CI: 1.16-24.05; p = 0.032). Cryptococcal meningitis is an important cause of death in HIV-infected patients. HIV-infected patients with a low CD4+ cell count, a headache, fever and altered consciousness should be investigated for CM and those with a high CSF cryptococcal antigen titer are at high risk for mortality.

    Seasonal smog produces particulate matters that are less than 10 microns in diameter (PM₁₀), which are known to have several impacts on the respiratory system. This study was to determine the association of an increased PM10 level due to seasonal smog in Chiang Mai and emergency visits for asthma and chronic obstructive pulmonary disease (COPD) exacerbations. A retrospective cross-sectional study was conducted between the months of January and March from 2006 until 2009. The association of an increased PM₁₀ level and the daily number of asthma and COPD exacerbations were analyzed using a generalized linear model; a Poisson regression model was fit to the number of daily emergency visits using predictor variables: lags of PM10, day of the week, and time. There were a total of 917 emergency visits for acute exacerbations of asthma and COPD, with a median of 2 visits per day (range 0-10). The median PM₁₀ level during the same interval was 64.5 microgram per cubic meter (μg/m3) (16-304). For every 10 μg/m3 rise in PM10 concentration, there was a lag time of 6 days for asthma exacerbations [Adjusted relative risk (RR)=1.020; 95% confident interval (CI), 1.001-1.040; (p=0.014)], 7 days for COPD exacerbations [RR=1.030; 95%CI, 1.010-1.050 (p=0.024)] and 7 days for all exacerbations [RR=1.030 95%CI, 1.010-1.040 (p<0.001)]. This study confirms the effect of increasing PM₁₀ concentrations from seasonal smog on asthma and COPD exacerbations. However, there was an approximately 1 week lag time between the elevated PM₁₀ levels and time to emergency visits due to disease exacerbation.

    The objective of this study is to investigate the access to antiretroviral treatment among human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) patients in Chiang Mai province, Thailand. Access to antiretroviral treatment is defined in terms of availability, affordability, and acceptability. The data for the study were collected during the period of April 1, 2012-May 31, 2012 from a sample of 380 HIV/AIDS patients in eight hospitals who had received antiretroviral treatment for more than 6 months at the time of data collection. The results of the study show that for most patients, the average traveling time to access health care was acceptable, but the nearly half day waiting time caused them to be absent from their work. In particular, it took longer for patients in the rural and lower income groups to access the treatment than the other groups. Their travel times and food costs relating to the treatment were found to be relatively high and therefore these patients had a higher tendency to borrow or seek financial assistance from their relatives. However, due to improvements in the access to treatment, most patients were satisfied with the services they received. The results imply that policy should be implemented to raise the potential of subdistrict hospitals where access to antiretroviral treatment is available, with participating HIV/AIDS patients acting as volunteers in providing services and other forms of health promotion to new patients. Privacy issues could be reduced if the antiretroviral treatment was isolated from other health services. Additionally, efforts to educate HIV/AIDS patients and society at large should be made.

Empregou-se o método de Sullivan, combinando as tábuas de vida do Instituto Brasileiro de Geografia e Estatística (IBGE para 1998 e 2008 e estimativas intervalares das prevalências de incapacidade funcional, percepção de saúde e doenças crônicas da Pesquisa Nacional por Amostra de Domicílios (PNAD 1998 e 2008. Além do aumento da expectativa de vida, observaram-se aumentos significativos e similares da expectativa de vida saudável nas dimensões de percepção do estado de saúde e incapacidade funcional em quase todas as idades. As mulheres apresentaram maiores expectativas de vida, se comparadas aos homens, porém esperaram viver por mais tempo com saúde ruim, independentemente do indicador utilizado para mensurar saúde. Mesmo que a forma de mensurar saúde possa variar entre os estudos, dificultando comparações, é notável a desvantagem feminina em relação à expectativa de vida saudável.

    Full Text Available O artigo tem por objetivo oferecer aos definidores de política pública, aos governantes e aos mais diversos grupos de interesse da população brasileira conhecimentos comparativos úteis para que opinem, decidam e ajam a respeito de mega e pequenos eventos, facilitando ainda a pesquisa bibliográfica de estudantes e pesquisadores. A literatura mostra que os efeitos de um megaevento são um tema controverso. No Brasil, sede da Copa das Confederações em 2013, da Copa do Mundo em 2014 e dos Jogos Olímpicos em 2016, ainda há um importante questionamento sobre se o país, tão carente de melhorias em áreas como saúde e educação, deveria sediar megaeventos como esses. Soma-se a isso o questionamento se não seria melhor priorizar pequenos eventos nos países em geral. Os governantes e empresas interessadas na realização de megaeventos frequentemente superestimam seus efeitos positivos para a sociedade anfitriã, enquanto a literatura especializada considera que o saldo dos efeitos reais não é necessariamente positivo e, mais, tende a ser negativo. Com base nisso, desenvolveu-se e tornou-se forte a linha de entendimento de que os pequenos eventos são mais benéficos, têm maiores possibilidades de sucesso e maior potencial de efeito socioeconômico positivo – sendo assim recomendáveis no lugar de megaeventos para os países em geral, o que inclui o Brasil.

    Intensity modulated radiotherapy (IMRT) is one of the modern techniques in cancer treatment, in which dose is delivered optimally into the shape of the tumor and minimally in surround benign tissues. In developed countries, this technique has been performed routinely by Linacs with MLC for tumors at the critical areas. In Vietnam, because of the wet climate, the use of Linacs with MLC is difficult to operate and maintain. However, IMRT can be implemented by Linacs without MLC via independent jaws, Jaws-only IMRT (JO-IMRT), in which beams are separated into many segments with different weights to optimize highest dose in the tumor and lowest dose in the surrounding health organs. Methods: We describe the new treatment technic application and compare it with normal radiotherapy method (3D-CRT). Results: From 7/2008, the Dep of Nuclear Medicine and Oncology at Bach Mai Hospital has been conducting JO-IMRT to treat cancer patients. Up to now, we have 81 cases treated by IMRT including head and neck cancers (NPC, larynx cancer, maxillary sinus cancer, brain tumor), cancers in the thorax (esophagus cancer, lung cancer, breast cancer), cancers in the pelvis (prostate cancer, cervical cancer, rectal cancer). On the average, beam number is from 5 to 9 and 5-9 segments per beam. Treatment time for a fraction is from 6 to 12 minutes with 2.25 Gy for CTV1 per day. Discrepancies of doses were below 3% (0.15 to 2.84%) between planning and practice. In plan, the preeminences with IMRT are clearly superior to 3D radiation therapy. In clinical, almost patients had good respond, whereas side effects were quite less than conventional radiotherapy. Conclusions: JO-IMRT is a modern technic with more advantage than normal 3D-CRT. It help radiation dose to concentrate maximally in treatment target while influence minimally for sensitive surrounding tissues. Another, it is a high technic to appropriate with the climatic condition in Vietnam. (author)

    The site effects and the source parameters, are inverted from a Fourier displacement spectra of seismograms that are corrected by geometrical spreading and regional attenuation valid for south center of Mexico(Ordaz and Singh, 1992). We used Genetic Algorithms (GA) to perform the non-linear inversion, like in the MAI method (Moya et al., 2000) . The GA have proved to produce better results than other traditional methods which are frequently trapped in a local minimum. GA is a method that mimics the evolution laws in living creatures. The best individuals reproduce and develop themselves with every generation. In our case each individual correspond to one source and the genes correspond to the source parameters. As in nature, the best source remain and are improved with each iteration. We assume that the site effect at each station are the same independently of the earthquake, because of that we can search for the combination of sources that can produce the smaller standard deviation of the estimated site effects from the different Fourier displacement earthquake spectra. Then we use the obtained site effects to generate a Fourier displacement spectra of an earthquake scenario. With this, we are able to compute the response spectra by means of random vibration theory (Reinoso et al., 1990). We apply this method to four stations located in the Acapulco City, Mexico, that recorded four earthquakes with epicenter located in the Guerrero Subduction Zone. The site effect estimated for one of the stations, called ACAZ, shows a good agreement with the estimated by Chávez-García et al. (1994) using spectral ratios between the ACAZ station and a rock reference site. Also we compare the response spectra from other earthquake, obtained by the former method and the response spectra computed using the acceleration record. We find an acceptable correlation between them. Chávez-García, J. Cuenca y M. Cárdenas (1994), "Estudio complementario de efectos de sitio en Acapulco

    The basic methods for determining selenium and tellurium in various objects are presented. The bichromatometric determination of Te in cadmium, zinc and mercury tellurides is based on oxidation of Te(4) to (6) in H 2 SO 4 with potassium bichromate. In steels, Te is determined photometrically with the aid of KI. The determination is hindered by Fe(3), Cu(2), Bi(3) and Se(4) ions, which must be separated. The extraction-photometric determination of Te in native sulfur is carried out with the aid of 5-mercapto-3-(naphthyl-2)-1,3,4-thiadiazolthione-2 (pH=4.8-5.0). The dyed complex is readily extracted with chloroform and benzene. The spectrophotometric determination of Te in selenium is performed with the aid of 3,5-diphenylpyrazoline-1-dithiocarbamate of sodium. Te is determined in commercial indium, arsenic and their semiconductor compounds photometrically with the aid of copper diethyldithiocarbamate. The method permits determining 5x10 -5 % Te in a weighed amount of 0.5 g. The chloride complex of Te(4) with diantipyriodolpropylmethane is quantitatively extracted with dichloroethane from hydrochloric acid solutions. Thus, any amounts of Te can be separated from Se and determined photometrically. The extraction-photometric determination of Te in commercial lead and bismuth is carried out with the aid of pyrazolone derivatives, in commercial copper with the aid of diantipyridolpropylmethane, and in ores (more than 0.01% Te) with the aid of bismuthol 2. Also described is the extraction-polarographic determination of Te in sulfide ores

    A diagnosis of chronic myeloid leukemia (CML) is made on discovery of the presence of a Philadelphia (Ph) chromosome. The success of the treatment of this form of leukemia with tyrosine kinase inhibitor (TKI) is monitored by reduction of the Ph chromosome. To compare the role of conventional cytogenetic (CC) methods with a real time quantitative polymerase chain reaction (RQ-PCR) and fluorescence in situ hybridization (FISH) for diagnosis and treatment monitoring of CML patients. The secondary outcome was to analyze the treatment responses to TKI in CML patients. This was a retrospective study of CML patients who attended the Hematology clinic at Chiang Mai University Hospital from 2005-2010. Medical records were reviewed for demographic data, risk score, treatment response and the results of CC methods, FISH and RQ-PCR. One hundred and twenty three cases were included in the study, 57.7% of whom were male with a mean age of 46.9 years. Most of the patients registered as intermediate to high risk on the Sokal score. At diagnosis, 121 patients were tested using the CC method and 118 (95.9%) were identified as positive. Five patients failed to be diagnosed by CC methods but were positive for BCR-ABL1 using the FISH method. Imatinib was the first-line treatment used in 120 patients (97.6%). In most patients (108 out of 122, 88.5%), a complete cytogenetic response (CCyR) was achieved after TKI therapy and in 86 patients (70.5%) CCyR was achieved long term by the CC method. Five out of the 35 analyzed patients in which CCyR was achieved by the CC method had a positive FISH result. Out of the 76 patients in which CCyR was achieved, RQ-PCR classified patients to only CCyR in 17 patients (22.4%) with a deeper major molecular response (MMR) in 4 patients (5.3%) and complete molecular response (CMR) in 55 patients (72.4%). In the case of initial therapy, CCyR was achieved in 95 patients (79.1%) who received imatinib and in both patients who received dasatinib (100%). For the

    Selenium biotransformation by lactic acid bacteria during the preparation of Se-enriched yogurt was evaluated. The study focused on the distribution of selenium in the aqueous soluble protein fraction and the detection of selenoamino acids. Screening of selenium in Tris-buffer-urea soluble fraction was carried out by sodium dodecyl sulphate polyacrylamide gel electrophoresis after pre-fractionating with asymmetric field flow fractionation using inductively coupled plasma-mass spectrometry as the detector. Selenium-containing fractions were identified by peptide mapping using nano LC-ESI/LTQMS. Proteins such as thioredoxin, glutaredoxin, albumin, β-lactoglobulin, and lactoperoxidase were identified in the selenium-containing fraction. All these proteins were detected in both the control and the selenium-enriched yogurt except chaperones, which were only detected in the control samples. Chaperones are heat-shock proteins expressed in response to elevated temperature or other cellular stresses. Selenium may have an effect on chaperones expression in Lactobacillus. For the amino acids analysis, selenocysteine was the primary seleno-containing species. Copyright © 2014 Elsevier Ltd. All rights reserved.

Com este propósito, o modelo apresentado por Monden é adotado como ponto de partida, introduzindo-lhe, no entanto, significativas mudanças. Neste artigo, discute-se cada uma das relações mantidas pela autonomação e pelo CQZD com os diversos componentes do sistema.The interpretations of the Toyota Production System (TPS which point out to Just-In-Time (JIT and Kanban as its essence are evidence of restrictive understanding of its real reach and strength. The TPS has the "complete elimination of wastes " as its grounds and JIT and autonomation as its two pillars. Zero Defect Quality Control (ZDQC appears as essential support to the operation of autonomation and Systems working. In this paper it is proposed a model which may portray the above interpretation of TPS. On this purpose, the model proposed by Monden was taken up as a starting point. Nevertheless, it was necessary to introduce significant changes. It is also discussed the nature o@f links among autonomation, ZDCQ and all Systems components.

    Full Text Available Com a fragmentação do consumo de conteúdo pela Internet, e consequente pluralização da participação do usuário através de plataformas de redes sociais, novos desafios aos portais de notícias e entretenimento surgiram em agregar esses dois universos. O objetivo agora é permitir ao público consumir um assunto e manifestar sua opinião dentro de um ambiente híbrido, ao mesmo tempo de consumo e participação. Esse artigo desvenda alguns pontos da necessidade da construção deste tipo de experiência tomando como exemplo a Globo.com. Percebe-se que, quanto mais os usuários interagem entre si pelas redes, maior é a vontade irrefutável de opinar sobre os assuntos que tangem à sua vida e de refletir essas mensagens junto às entidades oficiais que tratam esses assuntos, propiciando o processo colaborativo.

  10. Programa Mais Médicos, aperfeiçoando o SUS e democratizando a saúde: um balanço analítico do programa

    Directory of Open Access Journals (Sweden)

    Oswaldo Gonçalves Junior

    Full Text Available Resumo Este trabalho visa analisar o Programa Mais Médicos (PMM enquanto política pública da saúde, descrevendo algumas de suas características principais e apresentando dados que permitam uma visão sobre seu desempenho, a fim de trazer à luz, além de outros aspectos, a discrepância entre os resultados alcançados e a oposição feita ao programa pelo Conselho Federal de Medicina e pelo Conselho Regional de Medicina do Estado de São Paulo. Tomando como referência o ciclo de políticas públicas, o trabalho trata com especial ênfase as etapas de formulação e implementação. Utilizando como referencial analítico os conceitos de insulamento burocrático e janela de oportunidades, argumenta-se que o PMM possui aspectos instigantes, seja pelas características insuladas que marcam seu processo de formulação - levando a crer que o programa se manteve alheio a pressões externas durante essa fase -, seja pelo caráter oportuno gerado pelas chamadas Jornadas de Junho de 2013, que criaram condições necessárias para o governo federal lançar uma iniciativa claramente polêmica. Essas características, associadas ao significativo impacto social do programa, propiciam reflexões com potenciais aprendizados para processos envolvendo políticas públicas.

    Directory of Open Access Journals (Sweden)

    Maria do Socorro Machado Freire

    Full Text Available Resumo Estudos na área da saúde pública consideram a intersetorialidade uma estratégia de promoção de equidade no enfrentamento dos determinantes sociais da saúde. O município de Sairé, membro da Rede Pernambucana de Municípios Saudáveis (RPMS, se destaca pela adoção de uma política intersetorial denominada Sairé Mais Saudável. Este estudo visou conhecer como essa política impulsionou a equidade local. Foi realizado um estudo de caso que utilizou linha do tempo com registro de eventos críticos, análise documental, entrevistas e observação participante. Como referência teórica, utilizou-se a Teoria Ator -Rede, o que permitiu que fosse evidenciada a importância da adoção da política municipal para o empoderamento e equidade local. Os resultados, alicerçados na linha do tempo, demonstraram que foi necessário haver inicialmente uma tradução cognitiva, realizada mediante a influência e a responsabilidade direta da RPMS, a qual facilitou uma segunda tradução, desta vez estratégica, com a construção da política ancorada no programa municipal e que agora está sendo traduzida logisticamente em ações concretas direcionadas à equidade. O papel de uma liderança estratégica, valorização da formação e do que já estava construído foram categorias fundamentais nesse processo de mudança local.

  13. A Mitigation Technique of High-Power MAI in the Multimedia Optical CDMA System with the Optical Power Selector

    Science.gov (United States)

    Ohba, Kohki; Miyazawa, Takaya; Sasase, Iwao

    In this paper, we propose a mitigation system of high-level multiple access interference (MAI) for multimedia optical Code-Division Multiple-Access (CDMA) systems using the optical power selector (OPS). The proposed system can eliminate high-intensity MAI at the receiver for low-priority users. Moreover, the proposed system can reduce by half the required number of code sequences compared to the conventional scheme. As a result, the proposed system can increase the number of weights at the same code-length and, thus, obtain higher code spreading gain. We analyze performances of the proposed system and show that both high-priority users and low-priority users achieve lower bit error rates in comparison to the conventional scheme.

    2007-01-01

    Lead and cadmium uptake was investigated for common deciduous street trees in Beijing in this study. Species having Cd accumulation included Populus tomentosa, Sophora japonica and Catalpa speciosa. P. tomentosa had the highest ratios between leaf and soil Cd (0.848), followed by S. japonica (0.536), C. speciosa (0.493), Paulownia tomentosa (0.453) and Juglans regia (0.415). Pb levels were high in leaves of C. speciosa, J. regia and Pa. tomentosa. S. japonica had the highest ratio between leaf Pb and soil Pb (0.146), followed by Pa. tomentosa (0.143), Ginko biloba (0.103) and C. speciosa (0.095). A predictive foliar metal accumulation index (MAI) was developed and C. speciosa was calculated to have the highest MAI value (53.8). This suggests that C. speciosa would be a good choice for planting in areas of Beijing where soil contamination with Cd and Pb may be a problem. - Catalpa speciosa had the highest MAI value

    2016-09-01

    The main objective of this article was to examine the context in which professionals working within the Mais Médicos (More Doctors) Program operate. This study used the infrastructure scale of primary health units (PHUs), which was recently developed by Soares Neto and colleagues to provide more information regarding the relationship between the infrastructure of PHUs and the Municipal Human Development Index (MHDI) of municipalities that received Mais Médicos Program doctors. Using exploratory and inferential statistics, the article shows that 65.2% of the PHUs that received Mais Médicos Program doctors had medium-quality infrastructure and only 5.8% of them had low-quality infrastructure. The correlation of 0.50 between the infrastructure indicator and the MHDI points to a moderate tendency for municipalities with low MHDIs to have more precarious PHUs. Using multiple linear regression analysis it can be inferred that the main factor that contributed to the increase in the infrastructure indicator of the PHUs was the average municipal income. On the other hand, the factor that negatively affected the infrastructure of the PHUs was being located in the north or northeast regions.

    A parasitological investigation on trematode metacercariae was made on 62 freshwater fishes of 13 species in northern Thailand; Cyclocheilichthys apogon, Puntioplites proctozysron, Labiobarbus siamensis, Barbodes gonionotus, Barbodes altus, Henicorhynchus siamensis, Osteochilus hasselti, Notopterus notopterus, Mystacoleucus marginatus, Anabas testudineus, Systomus orphoides, Morulius chrysophykadian, and Hampala macrolepidota. The fish were caught over the summer period (February-May 2007) from 2 Chiang Mai water reservoirs, i.e., the Mae Ngad (UTM 47Q E 503200, 47Q N 2119300) and the Mae Kuang Udomtara (UTM 47Q E 513000, 47Q N 2092600) Reservoirs in Chiang Mai province, Thailand. The prevalence of heterophyid (Haplorchis taichui and Haplorchoides sp.) metacercariae in these fish was 83.9% and 74.2% in the Mae Ngad and Mae Kuang Udomtara Reservoirs, respectively. The highest intensity of heterophyid metacercariae in H. siamensis in the Mae Ngad was 120.4 and that in P. proctozysron in the Mae Kuang Udomtara was 180.0. The fish, A. testudineus, C. apogon, and M. chrysophykadian, were not found to be infected with H. taichui metacercariae. The results show that the freshwater fish in Chiang Mai water reservoirs are heavily infected with H. taichui and Haplorchoides sp. metacercariae. PMID:18552549

    Full Text Available O presente texto discute alguns dos critérios que os órgãos financiadores da pesquisa utilizam para escolher os projetos contemplados nas ciências do esporte, embora essa questão seja importante também para os cientistas brasileiros de outros campos do conhecimento. Observa-se que as transformações realizadas nos últimos anos nos sistemas de fomento e classificação dos programas de pós-graduação resultaram no aumento da produtividade científica brasileira medida pelas publicações indexadas no contexto internacional. No entanto, a pressão institucional quantitativa pela publicação pode estar induzindo a graves distorções de comportamento entre os cientistas, o que compromete o próprio sentido do fazer científico e o futuro da ciência no Brasil. Uma comparação entre o tamanduá e a ciência produzida pelos brasileiros pode ser útil no entendimento de algumas propostas de ação para a comunidade científica ligada às ciências do esporte.

    . Furthermore, our results concerning the pair structure of the wave functions of the even-spin states in chains of even-even and odd-odd N = Z nuclei in the A 60 - 80 mass region revealed a clear interplay between isovector neutron-proton and like-nucleon pairing correlations. Nevertheless, detailed aspects of these properties are sensitive to the renormalization of the effective interaction in the pairing channels. Taking advantage of our microscopic investigations on the coexistence phenomena in this mass region, which have already past many experimental tests, we address the problem of the structure of the lowest few even-spin positive-parity states in 68 Se. Also we present details of the results obtained using a few slightly different prescriptions for the effective interaction in order to illustrate the above mentioned problems. The theoretical spectrum of 68 Se for even spin positive parity states is compared with the experimental results. (authors)

    Depression is a highly prevalent and recurrent mental disorder that impacts all aspects of human life. Undesirable effects of the antidepressant drugs led to the development of complementary and alternative therapies. Gan-Mai-Da-Zao-Tang (, gān mài dà zǎo tang) is a traditional herbal formula commonly used for the treatment of depression, but lack of scientific proof on its mechanism. It consisted of Glycyrrhiza uralensis Fisch. (licorice), Triticum aestivum L. (wheat) and Zizphus jujuba Mill. (jujube). The objective of this study is to investigate the antidepressant effects of Gan-Mai-Dazao-Tang and its ingredients in rats exposed to forced swimming test (FST). The 72 of male Nerl: Wistar rats (8 weeks old) were randomized into control (10 mL/kg bw H 2 O), licorice (0.4 g/kg bw), wheat (1.6 g/kg bw), jujube (0.5 g/kg bw), Gan-Mai-Da-Zao-Tang (2.5 g/kg bw of licorice: wheat: jujube in ratio of 5:20:6) and Prozac (18 mg/kg bw) groups. Samples were administered by oral gavage for 21 days. FST was performed on 21st day, with 15 min for pretest followed by 5 min for real test. Then, the animals were sacrificed and brain tissues were collected for monoamines analyses. The Gan-Mai-Da-Zao-Tang (LWJ) showed significantly down-regulation of immobility time, 3,4-dihydroxyphenylacetic acid (DOPAC) and DOPAC/dopamine (DA) turnover rates, and also enhanced the concentration of serotonin (5-HT) and DA in brain tissues, as compared with the control. The LWJ stated the potent antidepressant-like effect by modulating these monoamines concentration, while the licorice, wheat and jujube did not reported significant results as compared with control group. The positive control (Prozac) was noted with significantly reduction in body weight and appetite. In conclusion, the antidepressant-like effects of LWJ might be mediated by the regulation of monoamine neurotransmitters. Thus, it could beneficial in depression treatment as a complementary approach.

    2014-11-01

    Every year, during dry season, Chiang Mai and other northern provinces of Thailand face the problem of haze which is mainly generated by the burning of agricultural waste and forest fire, contained high percentage of particulate matter. Particulate matter 10 (PM10), being very small in size, can be inhaled easily to the deepest parts of the human lung and throat respiratory functions. Due to this, it increases the risk of respiratory diseases mainly in the case of continuous exposure to this seasonal smog. MODIS aerosol images (MOD04) have been used for four weeks in March 2007 for generating the hazard map by linking to in-situ values of PM10. Simple linear regression model between PM10 and AOD got fair correlation with R2 = 0.7 and was applied to transform PM10 pattern. The hazard maps showed the dominance of PM10 in northern part of Chiang Mai, especially in second week of March when PM10 level was three to four times higher than standard. The respiratory disease records and public health station of each village were collected from Provincial Public Health Department in Chiang Mai province. There are about 300 public health stations out of 2070 villages; hence thiessen polygon was created to determine the representative area of each public health station. Within each thiessen polygon, respiratory disease incident rate (RDIR) was calculated based on the number of patients and population. Global Moran's I was computed for RDIR to explore spatial pattern of diseases through four weeks of March. Moran's I index depicted a cluster pattern of respiratory diseases in 2nd week than other weeks. That made sense for a relationship between PM10 and respiratory diseases infections. In order to examine how PM10 affect the human respiratory system, geographically weighted regression model was used to observe local correlation coefficient between RDIR and PM10 across study area. The result captured a high correlation between respiratory diseases and high level of PM10 in

    Full Text Available A erosão do solo é a principal causa do empobrecimento precoce de terras produtivas e dentre as suas formas está a erosão laminar. Esta se caracteriza não apenas pela remoção de uma camada relativamente uniforme da superfície, mas também por seus nutrientes, sendo intensificada, portanto, pelas ações antrópicas. Para evitar ou reduzir seus impactos, fazem-se necessárias diretrizes para a adequação do uso e da ocupação às condições de cobertura vegetal, tipo de solo e topografia, através de mapas do potencial erosivo laminar da região de interesse, obtidos via sistemas de informações geográficas (SIG. Neste trabalho foi desenvolvido o mapeamento do potencial erosivo laminar da bacia do rio Japaratuba, SE (1685 km²; trata-se de uma região sujeita a intensa atividade agrícola, pecuária e de mineração, onde só restam 6% da vegetação nativa. Os resultados mostram que 48,71% da área da bacia ficam nas classes de médio e alto potencial erosivo, indicando que a bacia está bastante impactada devido aos usos inadequados para as condições de solo e declividades.Soil erosion is a natural phenomenon that reduces soil fertility and causes a great impact on agricultural areas. Laminar erosion is characterized by the removal of the top soil fairly uniformly as well as its nutrients, which is accelerated by human activities. To minimize the impacts it is necessary to adopt an adequate soil management that takes into account the type of the soil, relief, and vegetation cover. The soil management can be aided by mapping the erosive potential of a region using GIS tools. In this work, the technique that was used for mapping the erosive potential in the Japaratuba River Basin (1685 km² located in the State of Sergipe is presented. The results show that 48.71% of the basin area lie within medium and high erosive potentials zones, suggesting the inadequate land use for the soil types and relief within the basin.

    2014-02-01

    Full Text Available MaisTer® power is a combination of the well-known active ingredients Foramsulfuron (31,5 g/L, Iodosulfuron (1,04 g/L and the new developed ai Thiencarbazone-methyl (10,0 g/L and the new safener Cyprosulfamide (15,0 g/L. All three active ingredients belong to the group of the ALS inhibitors. The product can be applied with a dose rate of 1,5 L/ha or 1,0 L/ha. Foramsulfuron and Iodosulfuron will be taken up via the leaves of the plants whereas Thiencarbazone-methyl can penetrate the plants via the roots and the leaves. By using a dose rate of 1,5 L/ha a very good residual activity against new flushes of grass or broadleaf weeds will be observed. All relevant grass and broadleaf weeds in maize will be controlled after the application of MaisTer power including Polygonum species. If a dose rate of 1,0 L/ha is used it could make sense to add a tank mix partner like Aspect to complete the spectrum against some weeds like Chenopodium album or Polygonum convolvulus.

    Diurnal variation of particulate polycyclic aromatic hydrocarbons (PAHs) was investigated by collecting PM10 at three different sampling altitudes using high buildings in the city center of Chiang-Mai, Thailand, during the relatively cold period in late February 2008. At site-1 (12 m above ground level), B[a]P concentrations ranged from 30.3 -1,673 pg m-3 with an average of 506±477 pg m-3, contributing on average, 8.09±8.69% to ?PAHs. Ind and B[b]F concentrations varied from 54.6 to 4,579 pg m-3 and from 80.7 to 2,292 pg m-3 with the highest average of 1,187±1,058 pg m-3 and 963±656 pg m-3, contributing on average, 19.0±19.3% and 15.4±12.0% to ?PAHs, respectively. Morning maxima were predominantly detected in all observatory sites, which can be described by typical diurnal variations of traffic flow in Chiang-Mai City, showing a morning peak between 6 AM. and 9 AM. Despite the fact that most monitoring sites might be subjected to specific-site impacts, it could be seen that PAH profiles in Site-1 and Site-2 were astonishingly homogeneous. The lack of differences suggests that the source signatures of several PAHs become less distinct possibly due to the impacts of traffic and cooking emissions from ground level.

    This study was designed to determine the incidence of Streptococcus suis infection in slaughtered pigs raised in industrial facility and backyard system in Chiang Mai City, Thailand. A total of 90 tonsils and submaxillary salivary gland/lymph node samples from slaughtered pigs raised in industrial facility and 122 samples from slaughtered pigs raised in backyard system were collected. Isolation and identification of S. suis were conducted using standard bacteriological methods. Farm management and risk factor data were collected by a questionnaire. Serotyping and presence of virulence factor genes, epf, mrp and sly, were determined by multiplex PCR assay. The overall incidence of S. suis in this study was 9% (n = 212) and the incidence is significantly higher in districts located at a greater distance south of Chiang Mai City. S. suis serotype 2 was present more in healthy pigs (43%) than ill pigs (10%). Every S. suis isolate carried mrp and sly and ill pigs carried epf (80%) more than healthy pigs (57%). However, the probability of S. suis serotype 2 with epf+ (0.245) detected in healthy pigs was higher than in ill pigs (0.08) indicating people may have a higher risk of being infected with S. suis from healthy than ill pigs.

  5. Preliminary Monitoring of Soil gas Radon in Potentially Active Faults, San Sai District, Chiang Mai Province, Thailand

    Pondthai, P.; Udphuay, S.

    2013-05-01

    The magnitude of 5.1 Mw earthquake occurred in San Sai District, Chiang Mai Province, Thailand in December 2006 was considered an uncommon event due to the fact that there was no statistical record of such significant earthquake in the area. Therefore the earthquake might have been associated with a potentially active fault zone within the area. The objective of this study is to measure soil gas radon across this unknown fault zone within the Chiang Mai Basin, northern Thailand. Two profiles traversing the expected fault zone of soil gas radon measurements have been monitored, using TASTRAK solid state track nuclear detectors (SSNTDs). Radon signals from three periods of measurement show a distinctive consistent spatial distribution pattern. Anomalous radon areas along the profiles are connected to fault locations previously interpreted from other geophysical survey results. The increased radon signal changes from the radon background level with the signal-to-background ratio above 3 are considered anomalous. Such pattern of radon anomaly supports the existence of the faults. The radon measurement, therefore is a powerful technique in mapping active fault zone.

Paulo, veiculadas no mês de março de 2008 no caderno de variedades – Ilustrada – e no suplemento literário – Mais!. Assim, nos deparamos com uma diversidade de textos, compostos por gêneros discursivos característicos; entretanto, certos textos nos chamaram a atenção, pois, ainda que publicados como matérias de jornal, mais parecem textos literários, devido ao espaço em que são divulgados e, certamente, por conta do público a quem são destinados. Além disso, podemos conceber que os discursos representam o mundo e, assim, suas enunciações são parte integrante desse mundo representado, daí a associação entre essa concepção e a categoria de cena da enunciação. Desse modo, nos faremos valer dos conceitos de ethos e pathos, afinal, ainda que tenhamos dois cadernos de um mesmo jornal, estes periódicos são pensados tendo como público sujeitos distintos. E, ao considerar essas noções, pretenderemos apontar a construção de imagens de leitores na constituição das imagens dos cadernos analisados, bem como justificar essa abordagem distinta da Folha de S.

  16. Semiconductor-metal transition of Se in Ru-Se Catalyst Nanoparticles

    2009-03-01

    Ru-Se composite nanoparticles are promising catalysts for the oxygen reduction reaction (ORR) in fuel cells. Though the role of Se in enhancing the chemical stability of Ru nanoparticles is well established, the microscopic nature of Ru-Se interaction was not clearly understood. We carried out a combined investigation of ^77Se NMR and XPS on Ru-Se nanoparticles and our results indicate that Se, a semiconductor in elemental form, becomes metallic when interacting with Ru. ^77Se spin-lattice relaxation rates are found to be proportional to T, the well-known Korringa behavior characteristic of metals. The NMR results are supported by the XPS binding energy shifts which suggest that a possible Ru->Se charge transfer could be responsible for the semiconductor->metal transition of Se which also makes Ru less susceptible to oxidation during ORR.

    Full Text Available Abstract This study investigates the preparation of PbSe-ZnSe composite thin films by simultaneous hot-wall deposition (HWD from multiple resources. The XRD result reveals that the solubility limit of Pb in ZnSe is quite narrow, less than 1 mol%, with obvious phase-separation in the composite thin films. A nanoscale elemental mapping of the film containing 5 mol% PbSe indicates that isolated PbSe nanocrystals are dispersed in the ZnSe matrix. The optical absorption edge of the composite thin films shifts toward the low-photon-energy region as the PbSe content increases. The use of a phase-separating PbSe-ZnSe system and HWD techniques enables simple production of the composite package.

It adopts a cation-defective Th3P4-type arrangement with close to 8/9 of the unique neodymium-cation site occupied, leading to the composition Nd2.667Se4 (Z = 4 or Nd2Se3 (Z = 5.333, respectively. The Nd3+ cations are thus surrounded by eight selenide anions, forming trigonal [NdSe8]13− dodecahedra, whereas the Se2− anions exhibit a sixfold coordination, but due to the under-occupation of neodymium, each one is statistically surrounded by only 5.333 cations. The crystal studied was a merohedral twin with a 0.31 (6:0.69 (6 domain ratio.

    Visceral pentastomiasis (porocephalosis) caused by Armillifer armillatus larvae was incidentally diagnosed in a female striped hyena (Hyaena hyaena) of unknown age which died unexpectedly in 2013. The hyena had been imported from Tanzania 8years earlier and have been since then in a zoo in Chiang Mai, northern Thailand. Pathological examination revealed visceral nymph migrans of pentastomes throughout the intestine, liver, diaphragm, omentum and mesentery, spleen, kidneys, and urinary bladder. Polymerase chain reaction and sequencing that targeted the pentastomid-specific 18S rRNA gene determined 100% identity with reference sequence for A. armillatus, suggesting that its ova can infect the hyena to serve as an intermediate host for the parasite. Further studies to identify the source of infection, its risk factors, and host range for A. armillatus are important to determine its zoonotic potential and to better prevent and manage the disease to protect animal and human health.

    In this present study, the serotype of 40 Streptococcus suis isolates from submaxillary glands of pig carcasses sold in wet markets in Chiang Mai Province, northern Thailand, was investigated. Eleven serotypes, including types 2, 3, 4, 5, 7, 8, 9, 17, 21, 22 and 31, were found in the isolates by a Multiplex PCR combined with serum agglutination. Of the eleven serotypes present, type 3 was the most prevalent, while types 2, 4, 5 and 21 were of primary interest due to their human isolate serotype. The mrp+/epf - /sly - genotype was found to be the most prevalent genotype. This study indicates the importance of effective control of human S. suis infection due to raw pork or pig carcass handling in northern Thailand.

    High-quality ZnSe:Fe/ZnSe core/shell nanocrystals were prepared via a hydrothermal microemulsion technique. Effective surface passivation of monodisperse ZnSe:Fe nanocrystals is achieved by overcoating them with a ZnSe shell. The samples were characterized by means of XRD, EDX, TEM, PSD, XPS, photoluminescence, and Raman spectrum. The results show that the as-synthesized nanocrystals are cubic zinc blende ZnSe structure with high purity and the average particle size of ZnSe:Fe/ZnSe core/shell nanocrystal is larger than that of ZnSe:Fe core. The growth of ZnSe shell causes a small red shift in PL spectra, and then the PL quantum yield (QY) increases from 16% before shell growth to the maximum of 37% after increasing shell thickness up to 1.2 monolayers (ML). Moreover, both transverse optic (TO) and longitudinal optic (LO) phonon modes of ZnSe are shifted toward lower frequency as compared with the reported ones. -- Highlights: • ZnSe:Fe/ZnSe core/shell QDs were prepared by a hydrothermal microemulsion method. • ZnSe shell efficiently passivates surface defects by serving as a physical barrier. • The particle size and PL properties can be turned with the growth of ZnSe shell. • The luminescence efficiency and stability of QDs could be improved in this manner.

    Full Text Available This research aims to evaluate the Urban Heat Island Intensity (UHII and study the influences of population density, building density, and traffic density on the UHII in Chiang Mai city on each season and time. The surrounding air temperature was measured by thermocouples at a constant height of 2 m above the road by mobile surveying approach. The surveyed routes were divided into urban routes and rural routes. The UHII was calculated from the average surrounding air temperature difference between the urban and the rural areas. Experimental investigations were carried out in two seasons, consisting of summer (March-May, 2014 and winter (December 2013-February 2014. Experimental investigations were carried out in two periods, which were a daytime period (01.00-03.00 pm and a nighttime period (10.00 pm-00.00 am on Mondays, Wednesdays, and Sundays. The results show that the UHII in summer day, summer night, winter day, and winter night were 1.07°C, 1.27°C, 0.58°C, and 1.34°C, respectively. This implies that the temperature in Chiang Mai city’s urban area is higher than that in the rural area the entire year. Moreover, it was found that the UHII in summer day, winter day, and winter night were primarily affected by the traffic density with the sensitivity percentage of 87.50%, 72.73%, and 63.33%, respectively. In contrast, the UHII in summer night was mainly affected by the building density with the sensitivity percentage of 50.00%.

    Hilano José Rocha de Carvalho

    Full Text Available Resumo: No capitalismo contemporâneo, em que a aplicação produtiva da ciência, da técnica e da tecnologia assume um papel determinante, faz-se necessário buscar modelos de referência capazes de explicar os processos subjacentes à mesma, bem como os efeitos sociais mais amplos. Neste sentido, este artigo objetiva analisar criticamente o artigo intitulado Marx como referencial para análise de relações entre ciência, tecnologia e sociedade, apontando aspectos, face à sua tentativa de se apropriar dos conceitos marxianos da teoria do mais-valor para a compreensão crítica das relações CTS. A partir de uma confusão conceitual, fundada basicamente numa distinção deficiente entre duração, intensidade e produtividade do trabalho, os conceitos de mais-valor absoluto e relativo divergem das definições marxianas originais. Por isto e por centrar a análise na redução do valor da força de trabalho, a complexidade das relações capitalistas e o desenvolvimento social em função das mudanças científico-tecnológicas são deixados de lado.

  16. EPR of SeO2- and SeO3- radicals in alkaline borate glasses with 77Se isotope

    Galimov, D.G.; Tarzimanov, K.D.

    1977-01-01

    Alkaline borate glasses with 77 Se were investigated in order to establish the nature of selenium compounds and radicals in glasses. The relationship between alkali ions and the oxygen radical of selenium was determined by decoding the hyperfine structure of the alkaline borate glass EPR spectra obtained before and after γ-irradiation. The irradiated and non-irradiated glasses were characterized by hyperfine splitting of the EPR lines from the α- and β centres. Moreover, the irradiated samples were noted to have a line doublet (signal phi). With intenser reduction conditions of glass fusion, the intensities of α, β, and phi signals were noted to decline. This confirmes the suggestion that these centres were caused by oxygen compouds. The authors concluded that α and β signals were due to the paramagnetic centres of SeO 2 - and [SeO 2 - ]R + , and phi signal to the SeO 3 - radicals

    A 0.01 M CaCl(2) extraction is often used to asses the bioavailability of plant nutrients in soils. However, almost no correlation was found between selenium (Se) in the soil extraction and Se content in grass. The recently developed anion Donnan membrane technique was used to analyze chemical speciation of Se in the 0.01 M CaCl(2) extractions of grassland soils and fractionation of DOC (dissolved organic carbon). The results show that most of Se (67-86%) in the extractions (15 samples) are colloidal-sized Se. Only 13-34% of extractable Se are selenate, selenite and small organic Se (<1 nm). Colloidal Se is, most likely, Se bound to or incorporated in colloidal-sized organic matter. The dominant form of small Se compounds (selenate, selenite/small organic compounds) depends on soil. A total of 47-85% of DOC is colloidal-sized and 15-53% are small organic molecules (<1 nm). In combination with soluble S (sulfur) and/or P (phosphor), concentration of small DOC can explain most of the variability of Se content in grass. The results indicate that mineralization of organic Se is the most important factor that controls Se availability in soils. Competition with sulfate and phosphate needs to be taken into account. Further research is needed to verify if concentration of small DOC is a good indicator of mineralization of soil organic matter.

    Thin films of PbSe of 400-600 nm in thickness, were obtained via chemical deposition from a solution containing lead nitrate, thiourea and selenosufate. SnSe thin films of 90-180 nm in thickness, were also obtained by chemical deposition from a solution containing selenosulfate. Optical and electrical properties of these thin films were significantly altered by heating them in selenium vapor at 300 °C. Thin film PbSe has a bandgap (Eg) of 1.17 eV (direct gap, forbidden transitions), which decreases to 0.77 eV when it has been heated. Its electrical conductivity (σ) is p-type: 0.18 Ω-1 cm-1 (as-prepared), and 6.4 Ω-1 cm-1 when heated. Thin film SnSe is of orthorhombic crystalline structure which remains stable when heated at 300 °C, but its Eg increases from 1.12 eV (indirect) in as-prepared film to 1.5 eV (direct, forbidden transitions) upon heating. Its electrical conductivity is p-type, which increases from 0.3 Ω-1 cm-1 (as-prepared) to 1 Ω-1 cm-1 when heated (without Se-vapor). When SnSe film is heated at 300 °C in the presence of Se-vapor, they transform to SnSe2, with Eg of 1.5 eV (direct, forbidden) with n-type electrical conductivity, 11 Ω-1 cm-1. The Seebeck coefficient for the PbSe films is: +0.55 mV K-1 (as prepared) and +0.275 mV K-1 (heated); for SnSe films it is: +0.3 mV K-1 (as prepared) and +0.20 mV K-1 (heated); and for SnSe2 film, - 0.35 mV K-1. A five-element PbSe-SnSe2-PbSe-SnSe2-PbSe thermoelectric device demonstrated 50 mV for a temperature difference ΔT = 20 °C (2.5 mV K-1). For SnSe-SnSe2-SnSe-SnSe2-SnSe device, the value is 15 mV for ΔT = 20 °C (0.75 mV K-1). Prospect of these thin films in thermoelectric devices of hybrid materials, in which the coatings may be applied on distinct substrate and geometries is attractive.

    Full Text Available O tornar-se avó assinala um período de transição no ciclo de vida familiar, marcado por transformações psíquicas significativas para os avós, caracterizando a quarta individuação. Este trabalho teve como objetivo investigar a experiência de tornar-se avó e sua importância no processo de individuação. Foi utilizado delineamento de estudo de caso coletivo. Onze avós maternas, com idades entre 49 e 66 anos, cujas filhas tiveram seu primeiro filho, responderam a uma entrevista semi-estruturada. Todas as avós tinham tido seus primeiros netos e a entrevista referia-se a sua experiência como avós desses netos. Os dados mostraram que o ser avó é uma fonte de renovação e renascimento. O estudo propiciou que as participantes refletissem sobre seus diferentes papéis familiares: avó, mãe, neta e filha. Os dados sugerem que tornar-se avó possibilita que antigos conflitos sejam repensados, renovando antigos vínculos e desejos, o que permite que a avó dê mais um passo rumo à sua individuação.

  13. Overview of the Mechanics of the Active Mai'iu Low Angle Normal Fault (Dayman Dome), Southeastern Papua New Guinea

    The Mai'iu Fault is a corrugated low-angle normal fault (LANF) that has slipped >24 km. It emerges near sea level at 21° N dip, and flattens southward over the dome crest at 3000 m. This reactivated Paleogene suture is slipping at up to 1 cm/year based on previous GPS data and preliminary 10Be cosmogenic nuclide exposure scarp dating. An alignment of microseismicity (Eilon et al. 2015) suggests a dip of 30° N at 15-25 km depth. Pseudotachylites are abundant in lower, mylonitic parts of the footwall. One vein yielded 40Ar/39Ar ages of 1.9-2.2 Ma, implying seismicity at 8-10 km depth at the above slip rate. Widespread, antithetic normal faults in the footwall are attributed to rolling-hinge controlled yielding during exhumation. A single rider block is downfolded into synformal megamullion. Unconformities within this block, and ductile folding and conjugate strike-slip faulting of mylonitic footwall fabrics record prolonged EW shortening and constriction. Many normal and strike-slip faults cut the metabasaltic footwall recording Andersonian stresses and flipping between σ1 and σ2. To exhume the steep faults, the LANF must have remained active despite differential stress being locally high enough to initiate well-oriented faults—relationships that bracket the frictional strength of the LANF. Quantitative XRD on mafic and serpentinitic gouges reveal the Mai'iu fault core is enriched in weak clays corrensite and saponite. Hydrothermal friction experiments were done at effective normal stresses of 30-210 MPa, and temperatures of 50-450oC. At shallow depths (T≤200 oC), clay-rich fault gouges are frictionally weak (μ=0.13-0.15 and 0.20-0.28) and velocity-strengthening. At intermediate depths (T>200 oC), the footwall is frictionally strong (μ=0.71-0.78 and 0.50-0.64) and velocity-weakening. Velocity-strengthening is observed at T≥400 oC. The experiments provide evidence for deep unstable slip, consistent with footwall pseudotachylites and microseismicity at

It also aims to visualize the manner in which the sociability engendered by the Freemason lodges eventually contributed to the construction of a political culture, in which the practice of debate, criticism, and representation were essential elements allowing us to have a better understanding of the final years of Portuguese colonial rule in the American continent.

  16. Caenorhabditis elegans ATPase inhibitor factor 1 (IF1 MAI-2 preserves the mitochondrial membrane potential (Δψm and is important to induce germ cell apoptosis.

    Directory of Open Access Journals (Sweden)

    L P Fernández-Cárdenas

    Full Text Available When the electrochemical proton gradient is disrupted in the mitochondria, IF1 (Inhibitor Factor-1 inhibits the reverse hydrolytic activity of the F1Fo-ATP synthase, thereby allowing cells to conserve ATP at the expense of losing the mitochondrial membrane potential (Δψm. The function of IF1 has been studied mainly in different cell lines, but these studies have generated contrasting results, which have not been helpful to understand the real role of this protein in a whole organism. In this work, we studied IF1 function in Caenorhabditis elegans to understand IF1´s role in vivo. C. elegans has two inhibitor proteins of the F1Fo-ATPase, MAI-1 and MAI-2. To determine their protein localization in C. elegans, we generated translational reporters and found that MAI-2 is expressed ubiquitously in the mitochondria; conversely, MAI-1 was found in the cytoplasm and nuclei of certain tissues. By CRISPR/Cas9 genome editing, we generated mai-2 mutant alleles. Here, we showed that mai-2 mutant animals have normal progeny, embryonic development and lifespan. Contrasting with the results previously obtained in cell lines, we found no evident defects in the mitochondrial network, dimer/monomer ATP synthase ratio, ATP concentration or respiration. Our results suggest that some of the roles previously attributed to IF1 in cell lines could not reflect the function of this protein in a whole organism and could be attributed to specific cell lines or methods used to silence, knockout or overexpress this protein. However, we did observe that animals lacking IF1 had an enhanced Δψm and lower physiological germ cell apoptosis. Importantly, we found that mai-2 mutant animals must be under stress to observe the role of IF1. Accordingly, we observed that mai-2 mutant animals were more sensitive to heat shock, oxidative stress and electron transport chain blockade. Furthermore, we observed that IF1 is important to induce germ cell apoptosis under certain types of

    Small amount of Se atoms are used to tune the carrier concentrations (n H ) and electrical transport in Ag 2 Se. Significant enhancements in power factor and thermoelectric figure of merit (zT) are observed in the compositions of Ag 2 Se 1.06 and Ag 2 Se 1.08 . The excessive Se atoms do not change the intrinsically electron-conducting character in Ag 2 Se. The detailed analysis reveals the experiment optimum carrier concentration in Ag 2 Se is around 5 × 10 18  cm −3 . We also investigate the temperature of maximum zT and the thermoelectric transport during the first order phase transitions using the recently developed measurement system

    The (γ, n) cross sections of Se isotopes ( 76 Se, 78 Se) were measured to supply fundamental data for estimating the inverse reaction cross section, i.e., the 79 Se(n, γ) 80 Se cross section. The enriched samples and a reference 197 Au sample were irradiated with laser-Compton scattering (LCS) γ-rays. The excitation function of each (γ, n) cross section was determined for the energy range from each near neutron separation energy to the threshold energy of (γ, 2n) reaction. The energy point corresponding to each cross section was deduced using the accurately determined energy distribution of LCS γ-rays. Systematic (γ, n) cross sections for Se isotopes including 80 Se were compared with those calculated by using a statistical model calculation code TALYS. (author)

    Full text : The semiconductive InSe layer compound is characterized by a strong covalent bond inside the layers and a weak Van der Waals bonding between them. It was shown that across the layers of InSe single crystals at low temperatures (T ≤ 200 K) at direct current (dc) hopping conduction through localized states near the Fermi level takes place. The results of dc-conductivity of gamma-irradiated p-InSe and n-InSe : Sn layer single crystals have been presented in this work. ρ-InSe single crystal specimens grown by the Bridgman method were used in the experiments. Plates of the crystals under study were obtained by cleaving along the layers of single crystal ingots. The single-crystal InSe samples for electric measurements had the form of planar capacitors normal to the C axis of the crystals, with silver-paste electrodes. The thickness of the InSe samples was 300 mkm. Co 60 serves as the source of irradiation with energy of gamma-quantum equal to 1.3 MeV. The electric properties of non-irradiated and gamma-irradiated InSe crystals were measured under the same conditions. It is revealed that InSe and InSe : Sn (0.2 and 0.4 mole percent Sn) single crystals exhibit a variable range hopping conduction along a normal to their natural layers at temperatures T≤200 K in a dc electric field. From experimental data the parameters of localized states of p-InSe and n-InSe : Sn were calculated before and after gamma-irradiation. It is revealed that gamma-irradiation of p-InSe and n-InSe : Sn (0.2 and 0.4 mole percent Sn) single crystals leads to significant change of localized states parameters. After gamma-irradiation the density of states near the Fermi level increased, but their energy spread and the average jump distance decreased. The concentrations of radiated defects were estimated in p-InSe (5.18*10 1 7 sm - 3) and n-InSe : Sn (2.5*10 1 7 - 2.7*10 1 8 sm - 3) single crystals. The present results demonstrate that gamma-irradiation offers the possibility of tuning

    The survey was carried out to investigate the presence of potentially pathogenic free-living amoebae (FLA) during flood in Chiang Mai, Thailand in 2011. From different crisis flood areas, seven water samples were collected and tested for the presence of amoebae using culture and molecular methods. By monoxenic culture, FLA were detected from all samples at 37 °C incubation. The FLA growing at 37 °C were morphologically identified as Acanthamoeba spp., Naegleria spp. and some unidentified amoebae. Only three samples (42.8%), defined as thermotolerant FLA, continued to grow at 42 °C. By molecular methods, two non-thermotolerant FlA were shown to have 99% identity to Acanthamoeba sp. and 98% identity to Hartmannella vermiformis while the two thermotolerant FLA were identified as Echinamoeba exundans (100% identity) and Hartmannella sp. (99% identity). This first report of the occurrence of FLA in water during the flood disaster will provide information to the public to be aware of potentially pathogenic FLA.

    To report the use of intravitreal (IVT) injections of anti-vascular endothelial growth factor agents (anti-VEGF) and its complications. The authors performed a retrospective review of consecutive patients treated with IVT injection of anti-VEGF between May 2006 and December 2010 at Chiang Mai University Hospital. Demographic data and complications were registered. The present study included 1,006 eyes of 878 patients. Mean age was 60 years (range 1 month to 91 years). Mean follow-up time was 12 months (range 1 month to 54 months). Total injections were 2,077 given as 47, 210, 399, 575, and 846 injection per year between 2006 and 2010, respectively. Anti-VEGF agents were bevacizumab (1,878; 90.42%), ranibizumab (190; 9.15%), and pegaptanib (9; 0.43%). Indications for injection based on primary diagnosis were neovascular macular degeneration (38.5%), diabetic retinopathy (38%), and retinal vein occlusion (15.9%). The incidence of endophthalmitis was 0.048% (1/2,077) for all injections and 0.053% (1/1878)for bevacizumab. The use of IVT injections of anti-VEGF is increasing, especially the use of bevacizumab. Incidence of ocular and systemic complications after IVT injection of anti- VEGF was low with no significant difference among the three anti-VEGFs agents.

    To determine the degree of adherence to guidelines on the diagnosis of cephalopelvic disproportion (CPD) in Maharaj Nakorn Chiang Mai Hospital. The database ofpregnant women who underwent cesarean delivery due to CPD between 2010 and 2012 was reviewed The degree of adherence to guidelines on the CPD diagnosis was recorded The guidelines were from Royal Thai College of Obstetricians and Gynecologists (RTCOG) and the American Congress of Obstetricians and Gynecologists (ACOG) as gold standard criteria for CPD diagnosis. Four hundred sixty four pregnant women diagnosed as CPD were recruited. The adherence to guidelines either RTCOG or ACOG criteria was 80.4%. Of 91 cases that had incomplete criteria to diagnose CPD, 25 cases (27.5%) had been suspected offetal macrosomia and CPD was diagnosed during latent phase of labor Unfortunately, 76% of these fetuses had birth weight less than 4000 grams, which were unlikely to be macrosomia. The adherence to guidelines on the diagnosis of CPD was 80.4%. Almost one-third of the cases that had no adherence were false diagnosed of fetal macrosomia. Therefore, the strategy of accurate fetal weigh estimation may reduce unnecessary cesarean section from false diagnosis of CPD.

    To investigate the one-year mortality rate after osteoporotic hip fracture and to identify factors associated with that mortality rate. A retrospective review of 275 osteoporotic patients who sustained a low-trauma hip fracture and were admitted in Chiang Mai University Hospital during January 1, 2006 to December 31, 2007 was accomplished. Eligibility criteria were defined as age over 50 years, fracture caused by a simple fall and not apathologicalfracture caused by cancer or infection. Results of this one-year mortality rate study were compared to studies of hip fracture patient mortality in 1997 and the period 1998-2003. The average one-year mortality rate in 2006-2007 was 21.1%. Factors correlated with higher mortality were non-operative treatment, delayed surgical treatment, and absence of medical treatment for osteoporosis. The 2006-2007 mortality rate was slightly higher than for the 1997 and 1998-2003 periods. The one-year mortality rate after osteoporotic hip fracture of 21.1% was approximately 9.3 times the mortality rate for the same age group in the general population, indicating that treatment of osteoporosis as a means of helping prevent hip fracture is very important for the individual, the family, and society as a whole.

Between January 2009 and October 2011, patients aged 18 to 60 years with newly diagnosed nodal PTCLs at the Maharaj Nakorn Chiang Mai Hospital were enrolled to receive CHOEP-21 every three weeks for eight cycles. G-CSF prophylaxis was given to all patients. Twenty-four patients were enrolled. Twenty of them were male with a median age of 49 years. The majority of patients (66.7%) had PTCL, not otherwise specified (PTCL, NOS), and 95.8% of the patients were in stage III or IV. The overall response rate was 58% with 42% having complete response. The response rates were better among patients with ALK-negative anaplastic large cell lymphoma (ALCL; 100%) and angioimmunoblastic T-cell lymphoma (AITL; 85%) than those with PTCL, NOS (44%). With a median follow-up of 21 months, the patients had an estimated 2-year event-free survival, and an overall survival rate of 37.6% and 54.4%, respectively. The most common adverse effects were infection and hematologic toxicities that was manageable. Although CHOEP-21 induced favorable responses in patients with ALK-negative ALCL and AITL, the responses were not durable and further therapy is mandated in management of patients with nodal PTCL.

Median CD4+ count before TB treatment was 69 cells/mm(3) (interquartile range [IQR] 33, 151). The overall mortality was 3.5% (6 patients). Immune reconstitution inflammatory syndrome (IRIS) occurred in eight patients (6.0%). Disseminated TB infections increased risk of death (odds ratio [OR] = 2.55, 95% confidence interval [CI] 1.25, 5.18) and IRIS (OR = 9.16, 95% CI 1.67, 50.07). Initiating combination antiretroviral therapy (cART) within two months after TB treatment increased risk of IRIS (OR = 6.57, 95% CI 1.61-26.86) and physicians caring for HIV/TB co-infected patients should be aware of this condition.

    The prevalence of Centrocestus formosanus metacercariae was investigated in ornamental fish purchased from a pet shop in Chiang Mai, Thailand, including Carassius auratus (goldfish), Cyprinus carpio (Koi), Poecilia latipinna (Sailfin Molly), Danio rerio (Zebrafish), and Puntigrus tetrazona (Tiger barb). The parasite species was identified by the morphology of worms as well as by a molecular approach using ITS2. The results showed that 50 (33.3%) of 150 fish examined were infected with the metacercariae. The highest prevalence was found in C. auratus (83.3%), and the highest intensity was noted in C. carpio (70.8 metacercariae/fish). The most important morphological character was the presence of 32-34 circumoral spines on the oral sucker. The phylogenetic studies using the rRNA ITS2 region revealed that all the specimens of C. formosanus in this study were grouped together with C. formosanus in GenBank database. This is the first report on ornamental fish, C. carpio, P. latipinna, D. rerio, and P. tetrazona, taking the role of second intermediate hosts of C. formosanus in Thailand. Prevention and control of metacercarial infection in ornamental fish is urgently needed.

    The Weather Research and Forecasting (WRF v. 3.7) model was applied to model PM10 data in Chiang Mai city for 10-days during a high haze event utilizing updated land use categories from the Moderate Resolution Imaging Spectroradiometer (MODIS). A higher resolution meteorological lateral boundary condition (from 1 degree to 0.25 degree) was also used from the NCEP GDAS/FNL Global Tropospheric Analyses and Forecast Grid system. A 3-category urban canopy model was also added and the Thompson aerosol-aware microphysics parameterization scheme was used to model the aerosol number concentrations that were later converted to PM10 concentrations. Aerosol number concentration monthly climatology was firstly used as initial and lateral boundary conditions to model PM10 concentrations. These were compared to surface data obtained from two stations of the Pollution Control Department (PCD) of Thailand. The results from the modeled PM10 concentrations could not capture the variability (r = 0.29; 0.27 for each site) and underestimated a high PM10 spike during the period studied. The authors then added satellite data to the aerosol climatology that improved the comparison with observations (r = 0.45; 43). However, both model runs still were not able to capture the high PM10 concentration event. This requires further investigation.

    Full Text Available O ciberativismo, surgido na cultura hacker, constitui a principal referência para os movimentos de resistência às formas de dominação por controle difuso, exatamente porque é um movimento político que tematiza a liberdade de comunicação e informação. A despeito dos duros golpes sofridos pelo movimento, em decorrência da política de "guerra ao terror", o ciberativismo logrou produzir uma expressão no cinema documentário que inflete a tendência da retórica documentária subjetiva para um uso coletivo, a autopoiese de contrapúblicos.

    We report the design, fabrication, and characterization of colloidal PbSe nanocrystal (NC)-based photovoltaic test structures that exhibit an excitonic solar cell mechanism. Charge extraction from the NC active layer is driven by a photoinduced chemical potential energy gradient at the nanostructured heterojunction. By minimizing perturbation to PbSe NC energy levels and thereby gaining insight into the "intrinsic" photovoltaic properties and charge transfer mechanism of PbSe NC, we show a direct correlation between interfacial energy level offsets and photovoltaic device performance. Size dependent PbSe NC energy levels were determined by cyclic voltammetry and optical spectroscopy and correlated to photovoltaic measurements. Photovoltaic test structures were fabricated from PbSe NC films sandwiched between layers of ZnO nanoparticles and PEDOT:PSS as electron and hole transporting elements, respectively. The device current-voltage characteristics suggest a charge separation mechanism that Is distinct from previously reported Schottky devices and consistent with signatures of excitonic solar cells. Remarkably, despite the limitation of planar junction structure, and without film thickness optimization, the best performing device shows a 1-sun power conversion efficiency of 3.4%, ranking among the highest performing NC-based solar cells reported to date. © 2009 American Chemical Society.

    A transferable force field for the PbSe-CdSe solid system using the partially charged rigid ion model has been successfully developed and was used to study the cation exchange in PbSe-CdSe heteronanocrystals [A. O. Yalcin et al., "Atomic resolution monitoring of cation exchange in CdSe-PbSe heteronanocrystals during epitaxial solid-solid-vapor growth," Nano Lett. 14, 3661-3667 (2014)]. In this work, we extend this force field by including another two important binary semiconductors, PbS and CdS, and provide detailed information on the validation of this force field. The parameterization combines Bader charge analysis, empirical fitting, and ab initio energy surface fitting. When compared with experimental data and density functional theory calculations, it is shown that a wide range of physical properties of bulk PbS, PbSe, CdS, CdSe, and their mixed phases can be accurately reproduced using this force field. The choice of functional forms and parameterization strategy is demonstrated to be rational and effective. This transferable force field can be used in various studies on II-VI and IV-VI semiconductor materials consisting of CdS, CdSe, PbS, and PbSe. Here, we demonstrate the applicability of the force field model by molecular dynamics simulations whereby transformations are initiated by cation exchange.

    HIV infection among men who have sex with men, particularly in Thai urban settings and among younger cohorts, is escalating. HIV testing and counseling (HTC) are important for prevention and obtaining treatment and care. We examine data from a 2013 survey of males, 15-24 years, reporting past-year sex with a male and living in Bangkok or Chiang Mai. Almost three quarters of young MSM (YMSM) in Bangkok and only 27 % in Chiang Mai had an HIV test in the previous year. Associations for HIV testing varied between cities, although having employment increased the odds of HIV testing for both cities. In Bangkok, family knowledge of same sex attraction and talking to parents/guardians about HIV/AIDS had higher odds of HIV testing. Expanded HTC coverage is needed for YMSM in Chiang Mai. All health centers providing HTC, including those targeting MSM, need to address the specific needs of younger cohorts.

    The phonon dispersions and phonon density of states of LaSe are obtained, based on density functional perturbation theory and the norm-conserving pseudo-potential method. An anomaly in calculated phonon dispersion curves is presented and interpreted as a Kohn anomaly. The heat capacity of LaSe is calculated then. For the three-phonon process scattering, the lowest non-harmonic cubic terms of the interatomic potential are considered to obtain single-phonon relaxation rate by applying the Fermi's golden rule. For the boundary scattering, the average phonon relaxation time was obtained. Considering two kinds of phonon scattering mechanisms, we obtain the lattice thermal conductivity of LaSe.

    Size-controllable monodisperse CdSe nanocrystals with different organic capping were prepared based on the hot-injection method. The effective separation of nucleation and growth was achieved by rapidly mixing two highly reactive precursors. As a contrast, we prepared CdSe/CdS nanocrystals (NCs) successfully based on the selective ion layer adsorption and reaction (SILAR) technique. This inorganic capping obtained higher photoluminescence quantum yield (PLQY) of 59.3% compared with organic capping of 40.8%. Furthermore, the CdSe-epoxy resin (EP) composites were prepared by adopting a flexible ex situ method, and showed excellent stability in the ambient environment for one year. So the composites with both high PLQY of nanocrystals and excellent stability are very promising to device application.

    Full Text Available O Brasil ocupou o oitavo lugar em números absolutos de suicídios no mundo em 2012. Apesar do suicídio com arma de fogo (AF não ser a modalidade mais comum, é frequente seu encontro na prática pericial criminal. Na maioria dos suicídios com AF há apenas um disparo efetivo e o encontro de duas ou mais lesões de entrada classifica o suicídio como atípico. Neste estudo foram avaliados os suicídios atípicos com dois ou mais disparos efetivos de AF nas necropsias do Instituto Médico Legal de Belo Horizonte realizadas entre 2006 e 2012. Foram resgatados cinco casos, correspondendo a 2,63% do total de suicídios com AF autopsiados no período estudado. A maioria dos casos era do sexo masculino, solteira, tinha pele morena, apresentava idade média de 42,3 anos e recebeu atendimento médico previamente ao óbito. Em quatro casos foram observadas duas lesões de entrada de projéteis de AF e em apenas um foram observadas três. Todos apresentavam lesões de entrada no tórax, a maioria localizada na região peitoral esquerda. Em dois indivíduos houve lesões de entrada no tórax e na cabeça. A causa da morte da maioria foi traumatismo torácico perfuro-contuso. Apesar da necropsia forense ser crucial no estabelecimento da causa médica da morte e na avaliação da capacidade de desempenhar atos motores voluntários após um primeiro disparo, a investigação criminal de casos de suicídios atípicos é um trabalho multidisciplinar, onde cada uma das peças periciais deve se encaixar adequadamente para o estabelecimento correto da causa jurídica da morte.

    We have studied the emission spectra and structural properties of double CdSe/ZnSe quantum dot (QD) sheet structures grown by molecular beam epitaxy in order to elucidate the mechanisms of the electronic and strain field interaction between the QD planes. The thickness of the ZnSe barrier separating the CdSe sheets was in the range of 10-60 monolayers (ML) in the set of samples studied. We have found that coupling between dots in adjacent layers becomes relatively strong in CdSe/ZnSe double layers structures with 25-27 ML barrier, while it is rather weak when the barrier thickness exceeds 30 ML.

    Hollow NiSe-CoSe samples have been synthesized for the first time via a one-pot solvothermal approach. The strategy is robust enough to synthesize NiSe-CoSe nanoparticles with different NiSe to CoSe ratios but with a similar hollow structure. Co ions in the NiSe-CoSe nanoparticles play decisive role for formation of the hollow structure; otherwise, the nanoparticles become solid for the NiSe sample. When used as the positive electroactive materials for energy storage, the NiSe-CoSe samples show excellent electrochemical activity in alkaline electrolyte. Using the synergistic effect between NiSe and CoSe, the electrochemical performance of NiSe-CoSe can be tuned by varying the NiSe to CoSe ratios. The NiSe-CoSe sample with a NiSe to CoSe ratio of 4:2 shows the best electrochemical performance in terms of superior specific capacity, improved rate capability and excellent cycling stability. In addition, the electrochemical performance of NiSe-CoSe sample with a NiSe to CoSe ratio of 4:2 is also evaluated via assembling hybrid supercapacitors with RGO, and the hybrid supercapacitor delivers both high power and energy densities (41.8 Wh kg-1 at 750 W kg-1 and 20.3 Wh kg-1 at 30 kW kg-1).

Measurements including differential scanning calorimetry (DSC), density, and X-ray diffraction were performed. The effect resulting from the addition of CdSe or AgI has been highlighted by examining three series of different base glasses. The characteristic temperatures of the glass samples, including glass transition (T g ), crystallisation (T x ), and melting (T m ) temperatures are reported and used to calculate their ΔT = T x - T g and their Hruby, H r = (T x - T g )/(T m - T x ), criteria. Evolution of the total electrical conductivity σ and the room temperature conductivity σ 298 was also studied. The terahertz transparency domain in the 50-600 cm -1 region was pointed for different chalcogenide glasses (ChGs) and the potential of the THz spectroscopy was suggested to obtain structural information on ChGs.

    To determine the incidence of early postoperative complications and associated factors after primary trabeculectomy in Thai glaucoma patients. This was a retrospective observational study performed in Chiang Mai University Hospital. One hundred and eighteen glaucoma patients participated in the study. All glaucoma patients underwent primary trabeculectomy with mitomycin C (MMC) using fornix-based conjunctival flap technique between December 2011 and May 2013. Surgical complications during the first 3 months of follow-up were recorded, and associated risk factors were analyzed. The incidence of posttrabeculectomy complications was the main outcome measure. One hundred and eighteen eyes of 118 patients were included. Early postoperative complications developed in 55 eyes (56.7%). Complications included hypotony (25 eyes, 27.2%), serous choroidal detachment (CD) (14 eyes, 15.6%), subconjunctival hemorrhage (12 eyes, 13.0%), hyphema (11 eyes, 12.4%), bleb leak (8 eyes, 8.8%), encapsulated bleb (2 eyes, 2.2%), aqueous misdirection (1 eyes, 1.1%), corneal epithelial defect (1 eyes, 1.1%), and overfiltration (1 eyes, 1.1%). There were no reported cases of endophthalmitis or blebitis. Hypotony was associated with serous CD (P = 0.006), and hyphema was associated with neovascular glaucoma (NVG) patients (P = 0.009). NVG was not associated with the increased rate of surgical failure (P = 0.083). The incidence of early complications after first-time trabeculectomy with MMC was high (56.7%) in this Thai clinic setting, but most were transient and self-limited conditions. The correlations between hypotony and CD as well as hyphema and NVG were compatible with the previous studies.

    Internet addiction is common among medical students, and the prevalence is higher than the general population. Identifying and creating solutions for this problem is important. The aim of this study was to examine the prevalence and associated factors, particularly loneliness and interpersonal problems among Chiang Mai medical students. Of 324 first to sixth year medical students, 56.8% comprised females with a mean age of 20.88 (SD 1.8). All completed questionnaires related to the objectives and activities of internet use, the Young Internet Addiction Test, the UCLA loneliness scale, and the Interpersonal Problems Inventory were employed to identify internet addiction. In all, 36.7% of the subjects exhibited internet addiction, mostly at mild level. Amount of time used daily, loneliness and interpersonal problems were strong predictors (beta = 0.441, p < 0.05, beta = 0.219, p < 0.001 and beta = 0.203 p < 0.001, respectively), whereas age and sex were not. All objectives of using internet contributed to the variance of internet addiction score. For internet activities, only non-academic or studying contributed. The final model accounted for 42.8% of total variance of the internet addiction score. Even though most addiction was at a mild level, careful strategies should be applied to better understand the situation. Along with a screening for potential internet addiction among medical students, attention should be paid to identifying those who experience loneliness and interpersonal problems, because both are strong predictors that can be improved by a variety of appropriate intervention.

    The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups. This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1215 participants, 487 (40.1%) were lowland Thai and 728 (59.9%) were from ethnic minorities. Overall, 17.9% of respondents reported "ever had sex." Lowland Thai adolescents were more likely to have ever had sex compared with ethnic minority adolescents (AOR, 1.61; CI, 1.06-2.45; P< 0.01). A higher proportion of lowland Thai respondents reported having ≥ 2 lifetime sexual partners (51.9% vs. 33.3%, P = 0.003), or currently having a boy/girlfriend (59.9% vs. 45.3%, P< 0.001) compared to ethnic minority adolescents. Consistent condom use was low in both groups (22.6%). The common significant factors associated with "ever had sex" in both groups were "ever drunk alcohol in the past year" and "currently having a boy/girlfriend." Specifically, for lowland Thai youth, being around the age of 17 or 18 years and "ever used methamphetamine in the past year" were associated with increased odds of "ever had sex". For ethnic minority adolescents, being female and belonging to religions other than Buddhism were associated with decreased odds of "ever had sex". A substantially higher proportion of lowland Thai engage in risky sexual behaviors when compared to ethnic minorities. However, both groups remained vulnerable to HIV and other sexually transmitted infections. To minimize sexual risks, education program and school-based interventions are warranted to increase awareness of young people about risky behaviors and to promote essential life skills.

    Out-of-school youth in Thailand engage in risky sexual behavior that puts them at risk for contracting HIV infection and can have other negative sexual reproductive health outcomes. No study has examined risky sexual behaviors and compared them between Thai and non-Thai out-of-school youth. The current study compares sexual risk behavior and HIV testing behavior between out-of-school Thai and non-Thai youth. We conducted face-to-face interviews in this study population in urban Chiang Mai during 2014. Participants were recruited through convenience sampling from two main sources: non-formal education centers (NFECs) and social meeting places. We recruited 924 youth, aged 15-24 years, of whom 424 (45.9%) were Thai and 500 (54.1%) were non-Thai. The majority were attending NFECs (82.3%). Of the sexually experienced participants (57.7%), 75.4% did not use condoms consistently, and 50.3% had at least 2 lifetime sexual partners. Among the study participants, the Thai studied youth had significantly higher odds of ever having had sex (AOR=2.33; 95% CI: 1.56-3.49; p<0.001), having an earlier sexual debut (AOR=5.52; 95% CI: 2.71-11.25; p<0.001) and having a larger number of lifetime sexual partners (AOR=2.31; 95% CI: 1.37-3.88; p=0.002) than non-Thai participants. There was no significant difference between the Thai and non-Thai participants in terms of having HIV testing. The Thai studied youth were more likely to engage in risky sexual behavior than the non-Thai youth. However, both groups displayed risky sexual behaviors. Future research should explore indepth the drivers of risky sexual behaviors among both Thai and non-Thai youth.

    Tuberculosis (TB) among healthcare workers (HCWs) highly affects morbidity and TB transmission in hospitals. A retrospective cohort study of TB among HCWs (HCW-TB) was conducted using a registered database from 2003 to 2016 at Chiang Mai University Hospital to determine clinical and microbiological characteristics and treatment outcomes of HCW-TB. A total of 76 patients comprising 54 nurses (71.1%), 12 physicians (15.8%), and 10 paramedics (13.2%) were diagnosed with TB disease. The men to women ratio was 25:51, with a mean age of 37.0±11.6 years, a median work duration of 12.0 years (5-20) and a body mass index of 19.4±2.5 kg/m 2 . Within the HCW-TB group, 28 (36.8%) worked in the Medical Department, 12 (15.8%) worked in the Outpatient Department/Emergency Room, and 9 (11.8%) worked in the Surgical Department. Pulmonary TB (PTB) was the most common manifestation of HCW-TB (92.1%). Sputum acid-fast stains were positive among 28 (40.0%) HCWs with PTB. Mycobacterium tuberculosis cultures were positive in 26 (34.2%) patients. Drug susceptibility testing showed sensitivity to all first-line drugs (75.0%), resistance to any one first-line drug (20.8%), and multidrug-resistant TB comprised 4.2%. The end-of-treatment success rate was 100%. Therefore, TB control guidelines should be strictly implemented to prevent TB transmission in healthcare settings.

    The chemical composition of 122 rainwater samples collected daily from bulk and wet-only collectors in a sub-urban area of Chiang Mai (Thailand) during August 2005-July 2006 has been analyzed and compared to assess usability of a cheaper and less complex bulk collector over a sophisticated wet-only collector. Statistical analysis was performed on log-transformed daily rain amount and depositions of major ions for each collector type. The analysis of variance (ANOVA) test revealed that the amount of rainfall collected from a rain gauge, bulk collector and wet-only collector showed no significant difference ( ∝=0.05). The volume weight mean electro-conductivity (EC) values of bulk and wet-only samples were 0.69 and 0.65 mS/m, respectively. The average pH of the samples from both types of collectors was 5.5. Scatter plots between log-transformed depositions of specific ions obtained from bulk and wet-only samples showed high correlation ( r>0.91). Means of log-transformed bulk deposition were 14% (Na + and K +), 13% (Mg 2+), 7% (Ca 2+), 4% (NO 3-), 3% (SO 42- and Cl -) and 2% (NH 4+) higher than that of wet-only deposition. However, multivariate analysis of variance (MANOVA) revealed that ion depositions obtained from bulk and wet-only collectors were not significantly different ( ∝=0.05). Therefore, it was concluded that a bulk collector can be used instead of a wet-only collector in a sub-urban area.

    The transport of biomass burning (BB) aerosol from Indochina may cause a potential effect on climate change in Southeast Asia, East Asia, and the Western Pacific. Up to now, the understanding of BB aerosol composition modification during long-range transport (LRT) is still very limited due to the lack of observational data. In this study, atmospheric aerosols were collected at the Suthep/Doi Ang Khang (DAK) mountain sites in Chiang Mai, Thailand and the Lulin Atmospheric Background Station (Mt. Lulin) in central Taiwan from March to April 2010 and from February to April 2013, respectively. During the study period, an upwind and downwind relationship between the Suthep/DAK and Lulin sites (2400 km apart) was validated by backward trajectories. Comprehensive aerosol properties were resolved for PM2.5 water-soluble inorganic ions, carbonaceous content, water-soluble/insoluble organic carbon (WSOC/WIOC), dicarboxylic acids and their salts (DCAS), and anhydrosugars. A Modification Factor (MF) is proposed by employing non-sea-salt potassium ion (nss-K+) or fractionalized elemental carbon evolved at 580 °C after pyrolized OC correction (EC1-OP) as a BB aerosol tracer to evaluate the mass fraction changes of aerosol components from source to receptor regions during LRT. The MF values of nss-SO42-, NH4+, NO3-, OC1 (fractionalized organic carbon evolved from room temperature to 140 °C), OP (pyrolized OC fraction), DCAS, and WSOC were above unity, which indicated that these aerosol components were enhanced during LRT as compared with those in the near-source region. In contrast, the MF values of anhydrosugars ranged from 0.1 to 0.3, indicating anhydrosugars have degraded during LRT.

    Based on the current tools, de novo secretome (full set of proteins secreted by an organism) prediction is a time consuming bioinformatic task that requires a multifactorial analysis in order to obtain reliable in silico predictions. Hence, to accelerate this process and offer researchers a reliable repository where secretome information can be obtained for vertebrates and model organisms, we have developed VerSeDa (Vertebrate Secretome Database). This freely available database stores information about proteins that are predicted to be secreted through the classical and non-classical mechanisms, for the wide range of vertebrate species deposited at the NCBI, UCSC and ENSEMBL sites. To our knowledge, VerSeDa is the only state-of-the-art database designed to store secretome data from multiple vertebrate genomes, thus, saving an important amount of time spent in the prediction of protein features that can be retrieved from this repository directly. VerSeDa is freely available at http://genomics.cicbiogune.es/VerSeDa/index.php. © The Author(s) 2017. Published by Oxford University Press.

    Full Text Available Os fungos do gênero Candida são capazes de produzir infecções superficiais ou sistêmicas em indivíduos com baixa resposta imunológica. Estes fungos promovem infecções a partir da sua capacidade de formar biofilmes. Os biofilmes formados por C. albicans são mais resistentes aos tratamentos antifúngicos convencionais. Portanto o objetivo deste trabalho foi avaliar e comparar o potencial antifúngico dos compostos organocalcogêneos (PhSe2 e (p­-Cl-PhSe2 sobre os biofilmes de C. albicans. Suspensões de C. albicans foram incubadas para a formação do biofilme e estes foram tratados com os compostos organocalcogêneos por 24 horas. Os resultados obtidos demonstraram o potencial antifúngico de ambos compostos sobre o biofilme formado por C. albicans, inibindo a viabilidade do biofilme e reduzindo a quantidade de células planctônicas. Esses compostos apresentaram uma resposta terapêutica promissora, uma vez que as opções para tratamento de infecções fúngicas é limitado.

    We report first-principles band structure calculations that show that ZnSe/CuInSe 2 has a significant valence band offset (VBO, ΔE v ): 0.70±0.05 eV for the relaxed interface and 0.60±0.05 eV for the coherent interface. These large values demonstrate the failure of the common anion rule. This is traced to a stronger Cu,d-Se,p level repulsion in CuInSe 2 than the Zn,d-Se,p repulsion in ZnSe. The VBO was then studied by synchrotron radiation soft x-ray photoemission spectroscopy. ZnSe overlayers were sequentially grown in steps on n-type CuInSe 2 (112) single crystals at 200 degree C. In situ photoemission measurements were acquired after each growth in order to observe changes in the valence band electronic structure as well as changes in the In 4d and Zn 3d core lines. Results of these measurements reveal that the VBO is ΔE v =0.70±0.15 eV, in good agreement with the first-principles prediction

    The size-dependent optical and electronic properties of semiconductor nanocrystals have drawn much attention in the past decade, and have been very well understood for spherical ones. The advent of the synthetic methods to make rod-like CdSe nanocrystals with wurtzite structure has offered us a new opportunity to study their properties as functions of their shape. This dissertation includes three main parts: synthesis of CdSe nanorods with tightly controlled widths and lengths, their optical and dielectric properties, and their large-scale assembly, all of which are either directly or indirectly caused by the uniaxial crystallographic structure of wurtzite CdSe. The hexagonal wurtzite structure is believed to be the primary reason for the growth of CdSe nanorods. It represents itself in the kinetic stabilization of the rod-like particles over the spherical ones in the presence of phosphonic acids. By varying the composition of the surfactant mixture used for synthesis we have achieved tight control of the widths and lengths of the nanorods. The synthesis of monodisperse CdSe nanorods enables us to systematically study their size-dependent properties. For example, room temperature single particle fluorescence spectroscopy has shown that nanorods emit linearly polarized photoluminescence. Theoretical calculations have shown that it is due to the crossing between the two highest occupied electronic levels with increasing aspect ratio. We also measured the permanent electric dipole moment of the nanorods with transient electric birefringence technique. Experimental results on nanorods with different sizes show that the dipole moment is linear to the particle volume, indicating that it originates from the non-centrosymmetric hexagonal lattice. The elongation of the nanocrystals also results in the anisotropic inter-particle interaction. One of the consequences is the formation of liquid crystalline phases when the nanorods are dispersed in solvent to a high enough

    Full Text Available The rural areas of Northern Thailand are home to a large cultural diversity of ethnic minority groups. Previous studies have shown that young people in rural Thailand have low levels of knowledge on HIV/AIDS and high sexual risks. We compared sexual behaviors between the lowland Thai youth and the youth from ethnic minority groups.This is a cross-sectional quantitative study conducted among high-school Thai and ethnic students in Chiang Mai. From a total 1215 participants, 487 (40.1% were lowland Thai and 728 (59.9% were from ethnic minorities. Overall, 17.9% of respondents reported "ever had sex." Lowland Thai adolescents were more likely to have ever had sex compared with ethnic minority adolescents (AOR, 1.61; CI, 1.06-2.45; P< 0.01. A higher proportion of lowland Thai respondents reported having ≥ 2 lifetime sexual partners (51.9% vs. 33.3%, P = 0.003, or currently having a boy/girlfriend (59.9% vs. 45.3%, P< 0.001 compared to ethnic minority adolescents. Consistent condom use was low in both groups (22.6%. The common significant factors associated with "ever had sex" in both groups were "ever drunk alcohol in the past year" and "currently having a boy/girlfriend." Specifically, for lowland Thai youth, being around the age of 17 or 18 years and "ever used methamphetamine in the past year" were associated with increased odds of "ever had sex". For ethnic minority adolescents, being female and belonging to religions other than Buddhism were associated with decreased odds of "ever had sex".A substantially higher proportion of lowland Thai engage in risky sexual behaviors when compared to ethnic minorities. However, both groups remained vulnerable to HIV and other sexually transmitted infections. To minimize sexual risks, education program and school-based interventions are warranted to increase awareness of young people about risky behaviors and to promote essential life skills.

    Since the 1990s, there has been a proliferation of methamphetamine use in Thailand, particularly among young people. Simultaneously, risky sexual behaviors among this population have increased. This study examined the effects of a peer network intervention and a life skills intervention on methamphetamine and HIV risk behaviors among 18–25 year olds in Chiang Mai, Thailand. Between April 2005 and June 2007, we conducted a randomized behavioral trial to compare the efficacy of a peer educator, network-oriented intervention with a best practice, life-skills curriculum on methamphetamine use, sexual behaviors, and incident sexually transmitted infections (STIs). Follow-up occurred at three, six, nine, and twelve months. Both conditions consisted of seven, two hour, small group sessions. Longitudinal analyses of the three outcomes were conducted by fitting repeated measures logistic regression models using generalized estimating equations. Participants (N=983) attended a median of six sessions, with no differences between arms. At each follow-up visit, retention was greater than 85%. Participants were 75% male and were a median of 19 years old. Over time, participants in both conditions showed a significant and dramatic decline in self-reported methamphetamine use (99% at baseline versus 53% at 12-months, p<0.0001) and significant increase in consistent condom use (32% baseline versus 44% at 12 months, p<0.0001). Incident STIs were common, with no differences between arms. Chlamydia had the highest incidence rate, 9.85/100 person-years and HIV had a low incidence rate of 0.71/100 person-years. Among young Thais, we found that a peer educator, network-oriented intervention was associated with reductions in methamphetamine use, increases in condom use, and reductions in incident STIs over 12 months. We also found parallel reductions with the life skills condition. To our knowledge, this is the first such trial targeting this population. Small group interventions are an

    Reducing physical inactivity among the population is a challenge for many nations. Targeting leisure time physical activity (LTPA) may be useful in increasing overall physical activity as it is assumed it is associated with a higher degree of free choice and personal preference than physical activity at work and during travel. The study explored the prevalence of physical inactivity and focused on the overall level of energy expenditure and energy level spent during leisure time among those who were physically inactive and assessed the stages of change for LTPA among those who were physically inactive. A population-based survey was conducted in 2014 in Chiang Mai, Thailand using a stratified two-stage cluster sampling technique. The Global Physical Activity Questionnaire (GPAQ) was used to collect the data on physical activity. Sufficient levels of physical activity (PA) were defined as ≥150 min/week of moderate-intensity PA or ≥75 min/week of vigorous-intensity PA or ≥600 metabolic equivalent of task (MET)-minutes/week. Weighted analyses were used to estimate the prevalence of physical inactivity, the total energy expenditure and expenditure during LTPA as well as stages of change among the physically inactive population. A total of 1744 people (808 men and 936 women), aged 15 to 64 years, participated in the study. We estimated that a quarter (26%) of the population were physically inactive. Physical inactivity was more commonly found among women than men in most age groups. LTPA contributed a small proportion of overall PA. On average, physically inactive men spent 132.8 MET-minutes/week and inactive women spent 208.2 MET-minutes/week in overall PA which is well below the 600 MET-minutes/week recommend by the World Health Organization. Around 75% of physically inactive people had no intention of engaging in regular LTPA. About a quarter of the investigative population were physically inactive. Most physically inactive members of the population

    Certain methods and weapons are traditionally considered to be "mala in se", i.e. evil in themselves. Examples are mass rape campaigns and land mines. The article examines different interpretations of the principle that belligerents ought not to use such means. Some interpretations are reductionist...... in the sense that they see the principle as an instance of other principles regulating conduct in war (jus in bello), namely the principles of discrimination and proportionality. I suggest a horizontal and a vertical dimension of the latter. Resort to violence can then be unjustified if 1) the persons......-one should have to endure. I defend the vertical dimension of proportionality as a key to understanding the principle of mala in se and consider whether it leads to an absolute prohibition against such means...

    We present a study of entropy transport in Bi2Se3 at low temperatures and high magnetic fields. In the zero-temperature limit, the magnitude of the Seebeck coefficient quantitatively tracks the Fermi temperature of the three-dimensional Fermi surface at the Γ point as the carrier concentration changes by two orders of magnitude (1017 to 1019 cm-3). In high magnetic fields, the Nernst response displays giant quantum oscillations indicating that this feature is not exclusive to compensated semimetals. A comprehensive analysis of the Landau level spectrum firmly establishes a large g factor in this material and a substantial decrease of the Fermi energy with increasing magnetic field across the quantum limit. Thus, the presence of bulk carriers significantly affects the spectrum of the intensively debated surface states in Bi2Se3 and related materials.

  20. Properties of the CuGaSe2 and CuInSe2 (001) surface

    The main task of this work was to investigate the (001) CuGaSe 2 and CuInSe 2 surface in dependence of preparation and stoichiometry. The knowledge of the atomic structure as well as other surface properties is important in respect to optimization of novel thin film solar cells. For the characterization of the layers mainly Auger electron Spectroscopy, low-energy electron diffraction and photoelectron spectroscopy were implemented. The development of an appropriate procedure with Ar + sputtering and annealing combined with decapping enabled the preparation of clean and well-ordered surfaces. Different surface structures were observed in dependence of the layer preparation and composition. A (4 x 1) reconstruction was observed for the first time on CuGaSe 2 layers grown with a moderate Cu-excess after preparation by sputtering and annealing. Similarly a (4 x 2) reconstruction was detected on CuInSe2 surfaces of Cu-poor layers. A reconstruction could be also observed on Cu-poorer layers, however the facets/steps could not be completely removed. Cu-richer layers were facet-free, however the observed reconstruction was also weaker. Thus it was shown that in contrary to recent expectations, according to which only the (112) surface is stable, also the (001) can be stable under particular conditions. The appearance of facets or steps is correlated with the presence of CuIn 3 Se 5 or CuGa 3 Se 5 phases. This information is furthermore important for the understanding of grain boundaries in polycrystalline CuGaSe 2 and CuInSe 2 . Binding energy shifts were observed for the first time on all Se3d, In4d, Ga3d, Cu3d core levels of the reconstructed surfaces. By comparison with results from the literature from the similar ZnSe (100) surface a modell for the (4 x 2) reconstruction was proposed. The surface components in the Se3d, In4d and Cu3d emission were attributed to Se dimers or In and Cu adatoms respectively. The x 1 periodicity of the (4 x 1) reconstruction of CuGaSe 2 is

    Full Text Available OBJETIVO: Analisar os fatores associados ao uso de substâncias estimulantes por caminhoneiros para se manterem acordados. MÉTODOS: Survey com 854 motoristas em oito locais de concentração de caminhoneiros (sete postos de gasolina e um posto aduaneiro em região de fronteira em cinco municípios do Rio Grande do Sul, em 2006. O desfecho "uso de rebite" foi categorizado em "sim" ou "não". Foi realizada análise de regressão de Poisson com variância robusta para a seleção de variáveis do modelo, que foi composto por níveis socioeconômicos, demográficos, de informações sobre a profissão e sobre o consumo de álcool. RESULTADOS: O consumo de rebite para se manter acordado foi declarado por 12,4% dos caminhoneiros de forma isolada ou em combinação com outras substâncias (café, guaraná em pó, energéticos, cocaína aspirada. O rebite foi a substância mais citada por aqueles que consumiam algo para ficar acordados. A ingestão de bebidas alcoólicas foi prática de mais de 70% dos entrevistados, dos quais 45,1% relataram consumo pelo menos uma vez por semana. O uso de rebite esteve associado às faixas etárias mais jovens, ao aumento da renda, à maior duração das viagens e ao consumo de álcool. DISCUSSÃO: O aumento da remuneração dos caminhoneiros implica aumento da carga de trabalho. Isso produz desgaste físico e emocional, levando-os a buscar solução temporária no consumo de substâncias estimulantes. A redução do consumo abusivo de álcool e do uso ilícito de substâncias como anfetaminas por motoristas profissionais depende não só de políticas voltadas para a prevenção e tratamento de drogas, mas de políticas intersetoriais articuladas que garantam melhores condições de trabalho e de saúde aos caminhoneiros.

    Highlights: • The electronic and thermoelectric properties of SnSe bulk material are studied. • The ZT can reach as high as 1.87 along yy and 1.6 along zz direction at 800k. • SnSe is an indirect-band material, and SOC has little effect on the band structure. • The high ZT can be attributed to the intrinsically ultralow thermal conductivity. - Abstract: A first-principles study and Boltzmann transport theory have been performed to evaluate the electronic structure and thermoelectric properties of SnSe compound. The energy band structure and density of states are studied in detail. The electronic transport coefficients are then calculated as a function of chemical potential or temperature within the assumption of the constant relaxation time. The figure of merit ZT is obtained with the use of calculated thermoelectric properties and can reach as high as 1.87 along yy and 1.6 along zz direction at 800 K.

    Full Text Available A rather significant proportion of the Societas Europaeas (the European Company, or SE formed to date have had German roots. German corporate law has been enriched by an interesting alternative which meanwhile seems to have gained momentum. This contribution focuses on SEs incorporated by German entrepreneurs and provides an interesting account concerning the use of SEs in Germany in practice, such as Allianz, Fresenius, BASF and Porsche. Has the SE been used to circumvent rigid company law provisions or is it a more flexible and effective tool, perhaps, for company mobility? The practical motives behind setting up this company form are also reflected upon. These include: the facilitation of cross-border mergers; transfer of the registered office; the ‘European’ image; a more flexible form of co-determination in large companies (reduction of the number of supervisory board members; avoidance and freezing of co-determination for medium-sized enterprises; the appeal of the one-tier system and its endangerment by German co-determination; and flat and uniform structures for company groups. The author also briefly discusses some of the problems arising from the formation of SEs in Germany. He ultimately concludes that practice has shown that it is possible to work with the legal regime of the SE in Germany, which adds a new company form to those available in that Member State.

    Full Text Available Despite being close neighbors on the Periodic Table, selenium and tellurium present a totally different abilities to form glasses. Se is a very good glass former, and gives rise to numerous glass compositions which are popular for their transparency in the infrared range and their stability against crystallization. These glasses can be shaped into sophisticated optical devices such as optical fibers, planar guides or lenses. Nevertheless, their transparencies are limited at about 12 μm (depending on the thickness of the optical systems due to the relatively small mass of the Se element. On the other hand, tellurium is heavier and its use in substitution for Se permits to shift the IR cutoff beyond 20 μm. However, the semimetallic nature of Te limits its glass formation ability and this glass family is known to be unstable and consequently has found application as phase change material in the Digital Versatile Disk (DVD technology. In this paper, after a review of selenide glasses and their applications, it will be shown how, in a recent past, it has been possible to stabilize tellurium glasses by introducing new elements like Ga or I in their compositions.

    The structural and optical properties of the chalcopyrite CunGanSe2n and CunInnSe2n nanoclusters (n = 2, 4, 6, and 8) are investigated as a function of the size using a combination of basin-hopping global optimization and time-dependent density functional theory. Although the lowest energy structures are found to show almost random geometries, the band gaps and absorption spectra still are subject to systematic blue shifts for decreasing cluster size in the case of CunGanSe2n, indicating strong electron confinement. The applicability of the nanoclusters in photovoltaics is discussed. © 2015 American Chemical Society.

    Thinning of CdSe nanowires (NWs) with controllable size was achieved by a simple acid treatment and subsequent annealing on thick CdSe NWs synthesized from vapour phase growth. During acid treatment, not only the undesired impurities such as native oxides of Cd and Se could be etched, but surface reactions of CdSe NWs were also observed, resulting in the formation of a layer of elemental Se around a thinner CdSe core. As a result, a heterostructure of Se - CdSe nanostructure formed after acid treatment of CdSe NWs. Upon thermal annealing, the Se shell was effectively removed and thinned stoichiometric single-crystalline CdSe NWs could be obtained. It was observed that NWs could be thinned by up to {approx}60% in diameter by acid treatment and subsequent Se thermal desorption. The degree of thinning was controllable by adjusting the duration of acid treatment. The success of the thinning of CdSe NWs by simple acid treatment and the annealing process reported here opens a new processing route for obtaining stoichiometric CdSe NWs with controllable size reduction and improved aspect ratio. This can undoubtedly broadly improve the range of applications of 1D CdSe nanostructures and allow more exploration of their uni-directional properties. A correction was made to the last paragraph of section 3 on 18 September 2007. The corrected electronic version is identical to the print version.

    Organophosphate and carbamate pesticides have been widely used by farmers for crop protection and pest control. Inhibition of acetylcholinesterase (AChE) in erythrocyte and butyrylcholinesterase (BChE) in plasma is the predominant toxic effect of organophosphate and carbamate pesticides. Mae Taeng District, Chiang Mai Province, is one of the large areas of growing vegetables and fruits. Due to their regular exposure to these pesticides, the farmers are affected by this toxicity. The objective of the study was to examine the AChE and the BChE activity levels in the blood of 102 farmers for comparison of exposure in two cropping seasons, winter and hot. Blood samples were collected in December 2013 (winter) and April-June 2014 (hot). A total of 102 farmers joined the study, represented by 76 males (74.5 %) and 26 females (25.5 %). The age of most of the farmers was 53.4 ± 8.7 years. Out of 102, 21 farmers used carbamate pesticides. The results showed that the AChE and the BChE activity levels of all the farmers were 3.27 ± 0.84 Unit/mL and 2.15 ± 0.58 Unit/mL, respectively. The AChE and the BChE activity levels in males were 3.31 ± 0.88 Unit/mL and 1.97 ± 0.60 U/mL, respectively, during winter and 3.27 ± 0.82 Unit/mL and 2.15 ± 0.58 U/mL, respectively, during the hot season, and AChE and the BChE activity levels in females were 3.27 ± 0.82 U/mL and 2.44 ± 0.56 U/mL, respectively, during the hot season. The cholinesterase activity levels, both AChE and BChE, in the male farmers' blood had significant difference between the two seasons, while in the case of the female farmers, there was significant difference in the BChE activity levels, at p < 0.05. The BChE activity level was found to significantly correlate with self-spray (p < 0.05), which implies that the BChE activity decreased when they sprayed by themselves. The cholinesterase activity levels of the present study were lower than those of the other

    Differential cross sections for neutron elastic and inelastic scattering from {sup 76}Se, {sup 78}Se, {sup 80}Se and {sup 82}Se, have been measured at 8-MeV incident neutron energy and from {sup 76}Se and {sup 82}Se at 6- and 10-MeV incident energies. The differences observed in the elastic scattering cross sections are interpretable as the effects of isospin term in the scattering potentials. A full analysis of the elastic scattering data are presented.

    EXAFS functions had been extracted from measurements on the K edge of Se at different temperatures between 20 and 300 K. The analysis of the EXAFS of the filtered first two shells has been done in the wavevector range laying between 2 and 15.5 A -1 in terms of the cumulants of the effective distribution of distances. The cumulants C 3 and C 4 obtained from the phase difference and the amplitude ratio methods have shown the anharmonicity in the vibrations of atoms around their equilibrium position.

    Thermoelectric power of InSe samples doped with tin has been measured as functions of the doping concentration in the range of 0.01 to 10% Sn and of the temperature in the range of 50 to 550 K. In the low temperature range the results obtained are coherent with the two-dimensional behaviour of electrons proposed by other authors. About 100 K the results can be explained successfully by introducing the same scattering mechanisms used to interpret the temperature dependence of the electron mobility

    2016-08-10

    Semiconductor quantum rings are of great fundamental interest because their non-trivial topology creates novel physical properties. At the same time, toroidal topology is difficult to achieve for colloidal nanocrystals and epitaxially grown semiconductor nanostructures. In this work, we introduce the synthesis of luminescent colloidal CdSe nanorings and nanostructures with double and triple toroidal topology. The nanorings form during controlled etching and rearrangement of two-dimensional nanoplatelets. We discuss a possible mechanism of the transformation of nanoplatelets into nanorings and potential utility of colloidal nanorings for magneto-optical (e.g., Aharonov-Bohm effect) and other applications.

    We have fabricated wire structures with (sub)micron sizes in the charge-density wave conductor NbSe 3 . Electrical transport measurements include complete mode-locking on Shapiro steps and show that the patterning has not affected the CDW material. Our mesoscopic wires show strong fluctuation and hysteresis effects in the low-temperature current-voltage characteristics, as well as a strong reduction of the phase-slip voltage. This reduction can not be explained with existing models. We suggest that single phase-slip events are responsible for a substantial reduction of the CDW strain in micron-sized systems. (orig.)

    CuInSe2 powders were synthesized by solvothermal method, and then the CuInSe2/In2Se3 bulk samples were fabricated by spark plasma sintering (SPS) technique. To investigate the phase composition, the powders were determined by X-ray diffraction (XRD). The microstructures of the powders and bulk samples were observed by scanning electron microscopy (SEM). The transportation of the electronic properties and thermal conductivity were measured at room temperature to 700 K. According to the results, the CuInSe2 powders appeared in flower-like patterns which ranged from 3 μm to 6 μm. CuInSe2 powders were synthesized at 180∘C with a chalcopyrite structure. The Seebeck coefficient increased significantly in composite thermoelectric materials up to 200μVṡK-1 at 623 K. The thermal conductivity of the sample significantly decreases from the room temperature to 700 K. The CuInSe2 bulk composite by solvothermal method achieves the highest ZT value of 0.187 at 700 K.

Salientar a importância do exame oftalmológico preventivo e tratamento precoce das doenças oculares. FONTE DOS DADOS: Dados de literatura. SÍNTESE DE DADOS: A visão é um dos mais importantes sentidos no desenvolvimento físico e cognitivo normal da criança. Em recém-nascido prematuro, as funções visual, motora e cognitiva, quando comparadas às de crianças de termo em idade escolar, são prejudicadas. Isto se deve mais à imaturidade do sistema nervoso central do que a lesões localizadas em estruturas oculares e/ou corticais. A retinopatia da prematuridade, o estrabismo e os erros de refração são as principais alterações oftálmicas secundárias à prematuridade descritas na literatura. A retinopatia da prematuridade é uma das principais causas de cegueira prevenível na infância. Calcula-se que, em média, 562 crianças fiquem cegas por ano no Brasil, um custo socioeconômico alto, principalmente por se tratar de uma doença passível de tratamento. Muito pode ser feito pela criança com deficiência visual; programas de estimulação visual precoce permitem que a criança possa ter uma integração maior com seu meio.

    Dash, S.; Ravindren, S.; Boolchand, P.

    A universal feature of glasses is the stretched exponential relaxation, f (t) = exp[ - t / τ ] β . The model of diffusion of excitations to randomly distributed traps in a glass by Phillips1 yields the stretched exponent β = d[d +2] where d, the effective dimensionality. We have measured the enthalpy of relaxation ΔHnr (tw) at Tg of Se glass in modulated DSC experiments as glasses age at 300K and find β = 0.43(2) for tw in the 0 Se100-x glasses as x increases to 20%, the length of the polymeric Sen chains between the Ge-crosslinks decreases to n = 2. and the striking relaxation effects nearly vanish.

The new designs avoid the glass box style of school buildings, and glass walls have been adopted only on the ground floor, thus giving an impression of light and airiness to what used to be a partial basement. Classrooms have been designed in a simple manner, and give the impression of conventional rooms. Simple lines and materials have been chosen throughout. Strong contrasts in the external finish have been avoided, and colours provide a relaxing background to the intensive activities of the students. A constructional feature is the use of prefabricated concrete joists and supports. Outer walls consist of brick panels filling in the space between the visible concrete framework. Ceilings are of insulating boards, and the floors are covered with linoleum. Special attention has been devoted to the hall. In this case the roof is of white gypsum, and the only features are the grills covering the fluorescent lighting. The walls of this hall are of glass, and are covered with heavy velvet curtains. A balcony with hardwood posts adds a simple and friendly feature to the building. The furniture and drapery have been carefully chosen.

    Highlights: → CuInSe 2 phase increased gradually accompanied with a decrease in γ-In 2 Se 3 and no intermediate phase during calcination. → CuInSe 2 formation from Cu 2 Se and In 2 Se 3 powders follows a one-dimensional diffusion-controlled reaction with apparent activation energy of about 122.5 kJ/mol. → The solid reaction kinetics may be dominated by the diffusion of In 3+ ions. - Abstract: The reaction mechanism and CuInSe 2 formation kinetics using a solid state reaction from Cu 2 Se and In 2 Se 3 powders synthesized using a heating up process were investigated using X-ray diffractomy (XRD) and transmission electron microscopy (TEM). It was observed that the CuInSe 2 phase increased gradually, accompanied with a decrease in γ-In 2 Se 3 with no intermediate phase as the calcination temperature and soaking time were increased. The reaction kinetics was analyzed using the Avrami and polynomial kinetic model, suggesting that CuInSe 2 formation from Cu 2 Se and In 2 Se 3 powders follows a diffusion-controlled reaction with an apparent activation energy of about 122.5-182.3 kJ/mol. Cu 2 Se and In 2 Se 3 phases react and directly transform into CIS without the occurrence of any intermediate phase and the size of the newly formed CuInSe 2 crystallites was close to that of the Cu 2 Se reactant particle based on the TEM results, which indicated that the solid reaction kinetics may be dominated by the diffusion of In 3+ ions.

    Differential cross sections and vector analyzing powers were measured at an incident deuteron energy of 12.5 MeV for the 76 78 80 82 Se(d,p) 77 79 81 83 Se reactions. The data are compared with the predictions of the DWBA theory to determine the l-value, spin, parity and spectroscopic factor of the resolved states. High resolution measurements were made with a 100 cm broad-range magnetic spectrograph to determine the excitation energies of the states studied, and the possible existence of contaminants in the targets. Definitive spin and parity assignments are made to 16 states in 77 Se, 22 states in 79 Se, 17 states in 81 Se, and 18 states in 83 Se, fifteen of which were previously assigned. In addition, tentative spin assignments were made to one state in 83 Se. The spectrograph measurements allowed the determination of the excitation energies of anumber of additional states in each isotope. Among the 76 states studied in this work, ther are 8 2P/sub 3/2/ states, 4 1F/sub 5/2/ states 6 2P/sub 1/2/ states 4 1G/sub 9/2/ states, 31 2D/sub 5/2/ states, 10 3S/sub 1/2/ states, and 13 2D/sub 3/2 states.

    Since 2008, alcohol control policies in Thailand have been considered quite comprehensive. The study aimed to investigate the subsequent changes in alcohol outlet density and patterns of sales promotion, which may be useful for monitoring the effectiveness of policies and helpful for planning prevention strategies to reduce alcohol-related harms. All accessible routes in the Chiang Mai Municipality (Metropolitan: CMM) were surveyed in 2009, 2011 and 2014. During each round of survey, the geographical coordinates of alcohol outlets and educational institutions in the CMM were recorded using the Global Navigation Satellite System (GNSS). In addition, alcohol sales campaigns were documented. Three main trends emerged by 2014. The first was that alcohol outlet density had increased. Second, the average distances between alcohol outlets and educational institutions decreased with evidence of clustering near educational institutions. Lastly, increased advertising of alcohol promotions and new sales campaigns not previously seen in 2009 and 2011 promoted high volume drinking in Chiang Mai Municipality (CMM). Our study reflects the potential gaps between some of the intended consequences of alcohol control policies and the actural trends emerging in Chiang Mai, Thailand. Young people in CMM may be at a particularly high risk for alcohol-related problems due to high exposure to alcohol outlets and sales campaigns near their educational institution. © The Author 2015.

    Thailand's long-standing HIV sero-sentinel surveillance system for people who inject drugs (PWID) is confined to those in methadone-based drug treatment clinics and representative data are scarce, especially outside of Bangkok. We conducted probability-based respondent-driven sampling (RDS) surveys in Bangkok (n=738) and Chiang Mai (n=309) to increase understanding of local HIV epidemics and to better inform the planning of evidence-based interventions. PWID had different epidemiological profiles in these two cities. Overall HIV prevalence was higher in Bangkok (23.6% vs. 10.9%, pChiang Mai, HIV infections appear to be more recently acquired and PWID were younger and had higher levels of recent injecting and sexual risk behaviors with lower levels of intervention exposure. Methamphetamine was the predominant drug injected in both sites and polydrug use was common although levels and patterns of the specific drugs injected varied significantly between the sites. In multivariate analysis, recent midazolam injection was significantly associated with HIV infection in Chiang Mai (adjusted odds ratio=8.1; 95% confidence interval: 1.2-54.5) whereas in Bangkok HIV status was not associated with recent risk behaviors as infections had likely been acquired in the past. PWID epidemics in Thailand are heterogeneous and driven by local factors. There is a need to customize intervention strategies for PWID in different settings and to integrate population-based survey methods such as RDS into routine surveillance to monitor the national response.

    Sexual health is one of the key dimensions of health across all ages. Understanding risky sexual behaviors remains an important area of public health research. This study aimed to explore sexual health, risky sexual behaviors and factors associated with recent condom use as condom use is considered a main intervention proven to reduce negative health consequences of risky sexual behaviors, specifically related to sexually transmitted infections and unintended pregnancies. A stratified two-stage cluster sampling technique survey was conducted in Chiang Mai, Thailand. Information was obtained about age of first sexual intercourse, sexual activity, condom use, number of partners and history of drug/alcohol use prior to sexual activities within the past 3 months. A weighted analysis was performed to account for data clustering. It is estimated that most men (93%) and women (86%) in Chiang Mai have engaged in sexual intercourse. More than 70% of the people in Chiang Mai over age 30 remained sexually active in the past 3 months, even for populations over age 50. Eight percent of male teenagers reported having more than one sexual partner in the past 3 months. Regular condom use was reported in less than 5% of the population (6.6% men and 3.1% women). Our study demonstrated that sexual health is an important public health issue across all age groups. Condom use has been promoted as one way to minimize and prevent unintended consequences of sexual behavior but overall use remains low.

    Full Text Available A seleção de futebol do Brasil que conquistou o título de campeã mundial, na Copa do Mundo de 1994, nos Estados Unidos, contava com seis atletas “evangélicos”. Este grupo reduzido, que se considerava “escolhido”, coordenado por pessoas ligadas ao grupo Atletas de Cristo (ADC, encontrou uma explicação sui generis para a conquista do título: Deus. Analisando a trajetória de cada um dos seis atletas no período da competição, Alex Dias Ribeiro, diretor dos ADC, apresentou não só uma versão religiosa de um evento esportivo, como a suposta superioridade da “fé evangélica” em relação aos outros produtos religiosos. Trabalhamos neste artigo com a hipótese de que esta idéia de superioridade decorre da herança evangelical que separa convertidos e não-convertidos, com os primeiros sendo abençoados por Deus, além da mudança de linguagem interpretadora do mundo do convertido, realizada agora a partir de sua experiência religiosa. A conseqüência é um tipo de humildade evangélica que atribui as grandes ações a Deus, tanto na vida cotidiana quanto no esporte.

    Energy demand continues to increase in turn raising concerns about energy supply. In this paper, the author has tried to systematize the role of the energy sector in South Eastern (SE) Europe in the context of the European energy policy process. This should make the energy sector in SE Europe more visible and open to substantial activities and appropriate funding. This is important to assure its full alignment with the European energy policy process, and in so doing, make it less fragile. According to the SE European Energy Community Treaty, parties to the Treaty are obliged to implement reforms in the energy and environmental sector in accordance with the European Union's respective policy. This paper raises awareness of the environmental requirements that have been set, of renewable energy and its implementation, at the same time pointing out that the response in SE Europe has been at a low level. It is believed that this paper could draw attention to the existing problems and could contribute to the establishment of a common integrated energy market in SE Europe and the EU. (author)

    Homoepitaxial and heteroepitaxial ZnSe metal-semiconductor-metal (MSM) photodetectors were both fabricated and characterized. It was found that homoepitaxial ZnSe MSM photodetector could provide us smaller dark current and large photocurrent. With an incident wavelength of 448 nm, it was found that the maximum responsivities for the homoepitaxial and heteroepitaxial ZnSe photodetectors were 0.128 and 0.045 A/W, which corresponds to a quantum efficiency of 36 and 12%, respectively. Furthermore, it was found that we achieved the minimum noise equivalent power (NEP) of 7.6 x 10 -13 W and the maximum normalized detectivity (D *) of 9.3 x 10 11 cm Hz 0.5 W -1 from our homoepitaxial ZnSe photodetector. In contrast, NEP and D * of the heteroepitaxial ZnSe photodetector were 2.9 x 10 -12 W and 2.44 x 10 11 cm Hz 0.5 W -1 , respectively

    In this article we have synthesized p-type alloy of SnSe and Sb2Se3 (10 atomic %) to study the thermoelectric transport properties. The alloy was prepared by melt grown technique followed by spark plasma sintering and latter doped with 2 atomic % Ag to compensate the carrier density in order to achieve higher electrical conductivity (σ). Out of these, the doped sample resulted in the maximum figure of merit, ZT˜0.7 at 773 K due to the existence of the secondary phase AgSbSe2 and reduced lattice thermal conductivity (0.61 W m-1 K-1 at 300 K). The fitted lattice thermal conductivity shows that point defect and Umklapp scattering are the primary process of phonon scattering for all the samples whereas the fitted mobility data confirms acoustic phonon scattering along with point defect and grain boundary scattering to be the main carrier scattering mechanism. More over room temperature carrier density and electrical conductivity are found to increase for the doped sample which further corroborate (90%)SnSe-(10%)Sb2Se3:2%Ag to be a potential candidate for highly efficient thermoelectric materials.

    2002-01-01

    Full Text Available A partir da segunda metade da década de 90, aparece na literatura acadêmica brasileira uma série de novas categorias que poderiámos agrupar sob as apelações de "terceiro setor" e "economia solidária". A pesquisa concentra-se na segunda categoria e tem por objetovo identificar sua origem e a realidade que ela pretende abranger. Neste texto são expostas algumas definições que podem ser encontradas na literatura internacional a respeito de termos como economia social, economia solidária, terceiro setor e outros mais. Deste confronto aparece que os conceitos utilizados no Brasil para estudar o campo da economia solidária tendem a uma certa estreiteza devido à pouca ênfase sobre questões como o resgate histórico anterior aos anos 80, a pluralidade ideológica e o hibridismo econômico, porém demonstram sensibilidade quanto à construção de uma outra cultura econômica de mercado, economia estatal e economia de reciprocidade que a categoria de terceiro setor tende a mascarar. Em vista disto, constata-se a necessidade de repensar esta categoria e de questionar as grandes expectativas assentadas na for mação de uma economia solidária para a transformação da sociedade

    To establish the validity of various proposed structural models, we have investigated the structure of the binary As x Se 100-x chalcogenide glass family (x≤40) by high-resolution x-ray photoelectron spectroscopy. From the composition dependence of the valence band, the contributions to the density of states from the 4p lone pair electrons of Se and the 4p bonding states and 4s electrons of Se and As are identified in the top part of the band. The analysis of Se 3d and As 3d core-level spectra supports the so-called chain crossing model for the atomic structure of Se-rich As x Se 100-x bulk glasses. The results also indicate small deviations (∼3-8%) from this model, especially for glass compositions with short Se chains (25 40 Se 60 and of Se-Se-Se fragments in a glass with composition x=30 is established

The aims of this study were to investigate the effects of pharmacists' interventions on appropriateness of prescribing in elderly patients, and to explore the relationship between these results and hospital care utilization during a 12-month follow-up period.The study population from a previous randomized controlled study, in which the effects of a comprehensive pharmacist intervention on re-hospitalization was investigated, was used. The criteria from the instruments MAI, STOPP and START were applied retrospectively to the 368 study patients (intervention group (I n = 182, control group (C n = 186. The assessments were done on admission and at discharge to detect differences over time and between the groups. Hospital care consumption was recorded and the association between scores for appropriateness, and hospitalization was analysed.The number of Potentially Inappropriate Medicines (PIMs per patient as identified by STOPP was reduced for I but not for C (1.42 to 0.93 vs. 1.46 to 1.66 respectively, p<0.01. The number of Potential Prescription Omissions (PPOs per patient as identified by START was reduced for I but not for C (0.36 to 0.09 vs. 0.42 to 0.45 respectively, p<0.001. The summated score for MAI was reduced for I but not for C (8.5 to 5.0 and 8.7 to 10.0 respectively, p<0.001. There was a positive association between scores for MAI and STOPP and drug-related readmissions (RR 8-9% and 30-34% respectively. No association was detected between the scores of the tools and total re-visits to hospital.The interventions significantly improved the appropriateness of prescribing for patients in the intervention group as evaluated by the instruments MAI, STOPP and START. High scores in MAI and STOPP were associated with a higher number of drug-related readmissions.

    We evidence zero-dimensional exciton states trapped on isoelectronic Se centers in CdTe quantum wells, {delta}-doped with Se. Thanks to special precautions taken to have very high purity CdTe heterostructures, it is possible to observe, in photoluminescence spectra, sharp discrete lines arising from individual centers related to the Se doping. These emission lines appear at about 40 meV below the CdTe band gap energy. The most prominent lines are attributed to the recombination of excitons bound to nearest-neighbor selenium pairs in a tetrahedral CdTe environment. This assignment is confirmed by a common linear polarization direction of the emitted light, parallel to <110>. These excitons localized on individual isoelectronic traps are good candidates as single photon emitters (copyright 2010 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim) (orig.)

    To analyse the diffusion characteristics, photoluminescence (PL) spectroscopy has been carried out in extensive detail on single, as well as, ensembles of thermally annealed (TA) CdSe/ZnSe QDs. For a series of QD-ensembles, each annealed for t A = 30 s at temperatures from T A = 300-550 C, the change in the QD-composition has been calculated from the blue-shift of the exciton ground-state PL-emission, using a concentration function based on Fick's laws of diffusion. The diffusion length (L D ) and the activation energy (E A ) have been determined thereof. For the studied QDs, E A has been evaluated to be 2.2 eV. Additionally, TA results also in an enhancement of the PL-intensity and reduction of the full-width-at-half maximum (FWHM) of the spectra. This point towards an increased homogeneity of the QD-size and composition, and decrease in the concentration of defects around the QDs. For single CdSe/ZnSe QDs, TA has been varied from 100-240 C, in steps for 20 C, with t A kept fixed at 30 s. Finally, the evolution of the magneto-optic response with post-growth thermal annealing has been studied for both individual QDs and QD-ensembles. An external magnetic field, applied perpendicular to the plane of the QDs (Faraday configuration), results in Zeeman spin splitting of the ground exciton state. The emissions from the Zeeman-split states are left and right circularly polarized and from the degree of circular polarization (DCP), as well as, the spectral separation of the PL-peaks, the g-factor can be estimated. For CdSe/ZnSe QD-ensembles, the g-factor has been observed to change sign with TA. (orig.).

It is a rare event, occurring in the evolution of leprosy of Lucio and other forms of lepromatous leprosy. It has an exacerbated proliferation of Hansen bacilli in its pathophysiology, which invade blood vessel walls and injure endothelial cells, causing endothelial proliferation and decreasing the vascular lumen. This fact, associated with inflammatory reactions and changes in the coagulation system causes vascular thrombosis, ischemia, infarction and tissue necrosis, leading to the histopathological characteristic of the phenomenon. We report a case of lepromatous leprosy with irregular treatment that developed Lucio's phenomenon. Treatment with multidrug therapy, antibiotics, steroids and thalidomide achieved a favorable outcome.Define-se o fenômeno de Lúcio como uma variante da reação hansênica do tipo 2.

    Using density functional theory calculation, we show that oxygen (O) exhibits an interesting effect in CuInSe{sub 2} and CuGaSe{sub 2}. The Se atoms with dangling bonds in a Se-rich Σ3 (114) grain boundary (GB) create deep gap states due to strong interaction between Se atoms. However, when such a Se atom is substituted by an O atom, the deep gap states can be shifted into valence band, making the site no longer a harmful non-radiative recombination center. We find that O atoms prefer energetically to substitute these Se atoms and induce significant lattice relaxation due to their smaller atomic size and stronger electronegativity, which effectively reduces the anion–anion interaction. Consequently, the deep gap states are shifted to lower energy regions close or even below the top of the valence band.

    2001-01-01

    The present work describes two radiosynthetic pathways to prepare homocysteine[ 75 Se]selenolactone 1 starting from n.c.a. [ 75 Se]selenite 2. It was achieved either by alkylation reaction of n.c.a. methyl[ 75 Se]selenide 4 or by hydrolysis of alkylated 1,3-dicyclohexyl[ 75 Se]selenourea 11. N.c.a. methyl[ 75 Se]selenide 4 is available using sulfur as non-isotopic carrier. However, the radiochemical yield of the substitution of 2-tert.-butoxycarbonylamino-4-bromobutyric acid ethylester 5 with n.c.a. methyl-[ 75 Se]selenide is only in the range of 15%-20%. Birch reduction of protected n.c.a. [ 75 Se]selenomethionine 6 formed leads to a RCY of 5%-10% homocysteine[ 75 Se]selenolactone 1. Alternatively, the synthesis of homocysteine[ 75 Se]selenolactone 1 is possible by hydrolysis of the corresponding [ 75 Se]selenouronium salt 11 available by addition of 2-tert.-butoxycarbonylamino-4-bromobutyric acid ethylester 5 to 1,3-dicyclohexyl[ 75 Se]selenourea 10. A method was developed for the synthesis of 1,3-dicyclohexyl[ 75 Se]selenourea 10 by addition of c.a.

    A new composite material composed of GaSe and CdSe has been obtained by treatment of GaSe single-crystal lamellas in Cd vapors at temperatures of 773-853 K and intercalation of Cd interlayers. The structure and optical properties of the GaSe-CdSe composite material have been studied. The content of CdSe crystallites was found to grow with increasing treatment temperature or with increasing duration of treatment at a constant temperature. Analysis of XRD, PL, XPS, AFM, and Raman patterns has shown that the heterogeneous composite composed of micro and nanocrystallites of CdSe in GaSe can be obtained by Cd intercalation in a temperature range of 753-853 K. On the basis of Raman spectrum, the vibrational modes of the composite have been identified. The PL of these materials contains emission bands of free and bound excitons, donor-acceptor bands, and bands of recombination via impurity levels. The PL emission spectra measured at a temperature of 78 and 300 K for the composites result from the overlapping of the emission bands of the components of GaSe doped with Cd and the CdSe crystallites.

    To investigate the infection of Fasciola gigantica (F. gigantica) in domestic cattle from Chiang Mai province and molecular confirmation using ITS-2 region. The liver and gall bladder of Bubalus bubalis (B. bubalis) and Bos taurus (B. taurus) from slaughterhouses were examined adult worms and prevalence investigation. The species confirmation with phylogenetic analysis using ITS-2 sequences was performed by maximum likelihood and UPGMA methods. The total prevalences of infection in B. bubalis and Bubalus taurus (B. taurus) were 67.27% and 52.94% respectively. The respective prevalence in both B. bubalis and B. taurus were acquired from Doi-Saket, Muang, and Sanpatong districts, with 81.25%, 62.50% and 60.00% for B. bubalis and 62.50%, 50.00% and 47.06% for Bos taurus respectively. The species confirmation of F. gigantica and some related species by basing on maximum likelihood and UPGMA methods used, 4 groups of trematodes were generated, first F. gigantica group including specimen of Chiang Mai, second 2 samples of F. hepatica, third group of 3 rumen flukes; Orthocoelium streptocoelium, F. elongatus and Paramphistomum epliclitum and fourth group of 3 minute intestinal flukes; Haplorchis taichui, Stellantchasmu falcatus, Haplorchoides sp. and liver fluke; Opisthorchis viverrini respectively. These results can be confirmed the Giant liver fluke which mainly caused fascioliasis in Chiang Mai was identified as F. gigantica and specimens were the same as those of F. gigantica recorded in other different countries. Nucleotide sequence of ITS-2 region has been proven as effective diagnostic tool for the identification of F. gigantica. Copyright © 2014 Hainan Medical College. Published by Elsevier B.V.

    Full Text Available Metaphor is pervasive in literature, and metaphorical choices can be seen as central to what we call an author's 'style.' This study provides an illustrative overview, based on fifty-page prose excerpts from fourteen authors representing diverse genres and periods. Categorizing examples by frequency, syntactic form and meaning, a clear characteristic or combination of characteristics readily emerges for each novelist. Having covered these, we then look in more detail at the semantics of metaphor in Arundhati Roy's novel The God of Small Things. Finally, we hypothesize that an expanded study, considering the function of metaphors in text and their interre lationships, could yield an increasingly fine-grained measure of metaphorical style.A metáfora é uma constante na literatura, e escolhas metafóricas podem ser consideradas essenciais ao que chamamos do estilo do autor. Este estudo fornece uma revisão ilustrada, baseada em trechos de cinqüenta páginas, selecionadas de catorze autores que representam diversos gêneros e períodos. Quando categorizamos exemplos por freqüência, forma sintática, e significado, facilmente emerge uma característica evidente, ou uma combinação de características para cada autor. Nós então analisamos mais detalhadamente a semântica da metáfora no livro The God of Small Things, de Arundhati Roy. Finalmente, propomos que um estudo mais extensivo, considerando a função das metáforas e suas Inter-relações, pode resultar numa medida cada vez mais precisa do estilo metafórico.

    PM10 aerosol was collected between February and April 2010 at an urban site (CMU) and an industrial site (TOT) in Chiang Mai, Thailand, and characteristics and provenance of water-soluble inorganic species, carboxylates, anhydrosugars and sugar alcohols were investigated with particular reference to air quality, framed as episodic or non-episodic pollution. Sulfate, a product of secondary photochemical reactions, was the major inorganic salt in PM10, comprising 25.9% and 22.3% of inorganic species at CMU and TOT, respectively. Acetate was the most abundant monocarboxylate, followed by formate. Oxalate was the dominant dicarboxylate. A high acetate/formate mass ratio indicated that primary traffic-related and biomass-burning emissions contributed to Chiang Mai aerosols during episodic and non-episodic pollution. During episodic pollution carboxylate peaks indicated sourcing from photochemical reactions and/or directly from traffic-related and biomass burning processes and concentrations of specific biomarkers of biomass burning including water-soluble potassium, glutarate, oxalate and levoglucosan dramatically increased. Levoglucosan, the dominant anhydrosugar, was highly associated with water-soluble potassium (r = 0.75-0.79) and accounted for 93.4% and 93.7% of anhydrosugars at CMU and TOT, respectively, during episodic pollution. Moreover, levoglucosan during episodic pollution was 14.2-21.8 times non-episodic lows, showing clearly that emissions from biomass burning are the major cause of PM10 episodic pollution in Chiang Mai. Additionally, the average levoglucosan/mannosan mass ratio during episodic pollution was 14.1-14.9, higher than the 5.73-7.69 during non-episodic pollution, indicating that there was more hardwood burning during episodic pollution. Higher concentrations of glycerol and erythritol during episodic pollution further indicate that biomass burning activities released soil biota from forest and farmland soils.

    For the purpose of monitoring and forecasting equatorial ionospheric disturbances, SEALION (SouthEast Asia Low-latitude IOnospheric Network) has been developed since 2003 as a cooperation project by National Institute of Information and Communications Technology (NICT), King Mongkut's Institute of Technology Ladkrabang (KMITL) in Thailand, Chiang Mai University (CMU) in Thailand, National Institute of Aeronautics and Space (LAPAN) in Indonesia, Hanoi Institute of Geophysics (HIG), Vietnamese Academy of Science and Technology in Vietnam, Center for Space Science and Applied Research (CSSAR), Chinese Academy of Sciences in China, Kyoto University in Japan, and Solar-Terrestrial Environment Laboratory (STEL), Nagoya University in Japan. SEALION consists of five ionosondes, four GPS receivers, two GPS scintillation monitors, and a magnetometer. As a part of this project, we newly installed an all-sky imager (ASI) and a Fabry-Perot Interferometer (FPI) at Sirindhorn observatory in Chiang Mai (18.8N, 98.9E, Dip lat. 13.1), Thailand. This site is located near conjugate to EAR site in Kototabang, Indonesia. One of main targets of the ASI observation is the large-scale wave structure (LSWS) with wavelengths of 100-1000 km. The LSWS is thought to be connected to the generation mechanism of equatorial plasma bubbles (EPB). The optical observations in Chiang Mai started in February 2010, and we have detected several ionospheric disturbance events with these instruments In this paper, we will show the initial results of the optical observations from Sirindhorn observatory, and discuss the features of ionospheric disturbances in Southeast Asia.

    Full Text Available Terrestrial inputs of freshwater flux to Sermilik Fjord, SE Greenland, were estimated, indicating ice discharge to be the dominant source of freshwater. A freshwater flux of 40.4 ± 4.9×109 m3 y−1 was found (1999–2008, with an 85% contribution originated from ice discharge (65% alone from Helheim Glacier, 11% from terrestrial surface runoff (from melt water and rain, 3% from precipitation at the fjord surface area, and 1% from subglacial geothermal and frictional melting due to basal ice motion. The results demonstrate the dominance of ice discharge as a primary mechanism for delivering freshwater to Sermilik Fjord. Time series of ice discharge for Helheim Glacier, Midgård Glacier, and Fenris Glacier were calculated from satellite-derived average surface velocity, glacier width, and estimated ice thickness, and fluctuations in terrestrial surface freshwater runoff were simulated based on observed meteorological data. These simulations were compared and bias corrected against independent glacier catchment runoff observations. Modeled runoff to Sermilik Fjord was variable, ranging from 2.9 ± 0.4×109 m3 y−1 in 1999 to 5.9 ± 0.9×109 m3 y−1 in 2005. The sub-catchment runoff of the Helheim Glacier region accounted for 25% of the total runoff to Sermilik Fjord. The runoff distribution from the different sub-catchments suggested a strong influence from the spatial variation in glacier coverage, indicating high runoff volumes, where glacier cover was present at low elevations.

    Full Text Available La desaceleración económica que experimenta Colombia desde 1980 se explica por el estancamiento estructural de la economía y por la escalada de violencia relacionada con la expansión del narcotráfico. Los datos disponibles no rechazan esta hipótesis. El artículo plantea que la desindustrialización y el narcotráfico se forjaron en el mismo crisol: un modelo de desarrollo que ha integrado progresivamente la economía nacional a los mercados mundiales al tiempo que ha renunciado, también progresivamente, a la opción industrialista. Además, argumenta que la explosión del narcotráfico obedece a la profundización de la guerra contra las drogas en un contexto de demanda mundial creciente e inelástica.

    The preparation of a .sup.72Se/.sup.72As radioisotope generator involves forming an acidic aqueous solution of an irradiated alkali bromide target such as a NaBr target, oxidizing soluble bromide in the solution to elemental bromine, removing the elemental bromine, evaporating the resulting solution to a residue, removing hydrogen chloride from the residue, forming an acidic aqueous solution of the residue, adding a chelator that selectively forms a chelation complex with selenium, and extracting the chelation complex from the acidic aqueous solution into an organic phase. As the .sup.72Se generates .sup.72As in the organic phase, the .sup.72As may be extracted repeatedly from the organic phase with an aqueous acid solution.

    Amorphous selenium (a-Se) and a-Se_9_5Sb_5 alloy were prepared using melt quenching technique. X-ray diffraction (XRD) pattern confirmed the amorphous nature of the prepared samples. Composition of the prepared samples has been determined using Energy dispersive X-ray fluorescence (EDXRF) technique. Differential thermal analysis (DTA) confirmed the glassy nature of the prepared samples. Thin films of the prepared samples were deposited on glass substrate using thermal evaporation method. Amorphous nature of the deposited films was confirmed using XRD. Optical properties of these films were obtained from the UV-VIS transmission spectra, at normal incidence, over 200-1100 nm spectral range. The optical absorption edge was described by using the model given by the Tauc. Optical band gap of the deposited films was calculated using Tauc plot. Optical characterization showed that average transmission and optical band gap decreased with the addition of antinomy.

    Full Text Available ResumoEste estudo avaliou a estrutura de capital de companhias abertas brasileiras, no período de 2005 a 2012, verificando o papel das fontes de financiamento nas quais tais companhias se baseiam. Para tanto, foi avaliada a proporção das dívidas em 3 fontes distintas: as instituições financeiras, o mercado de capitais e as fontes com taxas de juros subsidiadas, estas últimas representando um fator institucional da economia brasileira. Foi utilizada uma amostra de 95 empresas, dentre as 150 maiores empresas com ações negociadas na Bolsa de Valores, Mercadorias e Futuros de São Paulo (BM&FBOVESPA. Por meio de modelos com dados em painel, os resultados mostram que as fontes de financiamento impactam a formação da estrutura de capital das empresas, exercendo influência tanto na alavancagem quanto na maturidade das dívidas. Em relação à alavancagem, empresas que têm maior proporção de seus recursos captados no mercado de capitais são mais alavancadas. O mesmo não acontece com as empresas que têm maior proporção de recursos subsidiados. Em relação à maturidade das dívidas, recursos de diferentes maturidades são captados em diferentes fontes: os recursos de menores maturidades são captados em instituições financeiras e os recursos de maiores maturidades são captados no mercado de capitais e nas fontes com taxas de juros subsidiadas - leia-se Banco Nacional de Desenvolvimento Econômico e Social (BNDES. Comparando-se os recursos do mercado de capitais com os recursos subsidiados, verifica-se que os primeiros têm maior maturidade. Tal resultado pode ser justificado em virtude do crescimento do mercado de capitais brasileiro nos últimos anos, a partir de 2009, de modo que as companhias estão se baseando no mercado de capitais para seus financiamentos de maior maturidade e nos recursos subsidiados, do BNDES, para seus financiamentos de maturidades intermediárias.

    The cloning, purification, crystallization and preliminary crystallographic studies of three DsbA-like proteins present in S. enterica serovar Typhimurium, SeDsbA, SeDsbL and SeSrgA, are reported. Pathogens require protein-folding enzymes to produce functional virulence determinants. These foldases include the Dsb family of proteins, which catalyze oxidative folding in bacteria. Bacterial disulfide catalytic processes have been well characterized in Escherichia coli K-12 and these mechanisms have been extrapolated to other organisms. However, recent research indicates that the K-12 complement of Dsb proteins is not common to all bacteria. Importantly, many pathogenic bacteria have an extended arsenal of Dsb catalysts that is linked to their virulence. To help to elucidate the process of oxidative folding in pathogens containing a wide repertoire of Dsb proteins, Salmonella enterica serovar Typhimurium has been focused on. This Gram-negative bacterium contains three DsbA proteins: SeDsbA, SeDsbL and SeSrgA. Here, the expression, purification, crystallization and preliminary diffraction analysis of these three proteins are reported. SeDsbA, SeDsbL and SeSrgA crystals diffracted to resolution limits of 1.55, 1.57 and 2.6 Å and belonged to space groups P2 1 , P2 1 2 1 2 and C2, respectively

    Full Text Available That schizophrenia has a better prognosis in non-industrialized societies has become an axiom in international psychiatry; the evidence most often cited comes from three World Health Organization (WHO cross-national studies. Although a host of socio-cultural factors have been considered as contributing to variation in the course of schizophrenia in different settings, we have little evidence from low-income countries that clearly demonstrates the beneficial influence of these variables. In this article, we suggest that the finding of better outcomes in developing countries needs re-examination for five reasons: methodological limitations of the World Health Organization studies; the lack of evidence on the specific socio-cultural factors which apparently contribute to the better outcomes; increasing anecdotal evidence describing the abuse of basic human rights of people with schizophrenia in developing countries; new evidence from cohorts in developing countries depicting a much gloomier picture than originally believed; and, rapid social and economic changes are undermining family care systems for people with schizophrenia in developing countries. We argue that the study of the long-term course of this mental disorder in developing countries is a major research question and believe it is time to thoroughly and systematically explore cross-cultural variation in the course and outcome of schizophrenia.O fato de que a esquizofrenia possui um melhor prognóstico em sociedades não industrializadas tornou-se um axioma na psiquiatria internacional; as evidências mais comumente citadas provêm de três estudos trans-nacionais da Organização Mundial da Saúde (OMS.

Em seguida, a partir da base de dados dos censos demográficos do Instituto Brasileiro de Geografia e Estatística de 1970 e 2000, compara distintos padrões e tendências de algumas variáveis relativas ao mercado de trabalho na população feminina e masculina. Esse enfoque discute em que medida as dinâmicas assistidas neste segmento também reproduzem uma divisão sexual do trabalho. Os principais resultados encontrados mostram que já nos anos 1970 a maioria das mulheres deste grupo trabalhava em tempo integral. Essa tendência se acentua nos trinta anos em questão, e nas demais variáveis observam-se tendências cada vez mais próximas às masculinas. No entanto, a permanência da segmentação ocupacional feminina e dos altos diferenciais salariais aponta para uma desconstrução ainda lenta dos constrangimentos que cercam a presença destas mulheres no mundo do trabalho.This article examines, from a gender perspective, the type of employability the population holding higher education degrees had over the last thirty years of the twentieth century.

  8. Charge confinements in CdSe-ZnSe symmetric double quantum wells

    2008-01-01

    The bound states in the (CdSe) N w (ZnSe) N b (CdSe) N w -ZnSe(001) symmetric double quantum wells are investigated versus the well width (N w ) and the barrier thickness (N b ). A calculation based on the sp 3 s * tight-binding method which includes the spin-orbit interactions is employed to calculate the bandgap energy, quantum-confinement energy, and band structures. The studied systems possess a vanishing valence-band offset (VBO = 0) in consistency with the well known common-anion rule, and a large conduction-band offset (CBO ≅ 1 eV), which plays an essential role in the confinement of electrons within the CdSe wells. The biaxial strain, on the other hand, plays another role in confining the holes at the interfaces (within the well regions) and thus enhancing the radiative efficiency. The induced-strain energy is estimated to be ∼35 meV. More importantly, the results show that, for a fixed barrier thickness, the double wells are able to confine a pair of bound states when they are very thin. By increasing the wells' width (N w ), further, a new pair of states from the conduction-band continuum falls into the wells every time N w hits a multiple of four monolayers (more specifically, for 4n w ≤4(n+1), the number of bound states is 2(n+1), where n is an integer). On the other hand, the barrier thickness (N b ) is shown to have no effect on the number of bound states, but it solely controls their well-to-well interactions. A critical barrier thickness to switch off these latter interactions is estimated to occur at about N crit b ≅ 9 (L crit b ≅ 25∼AA. Rules governing the variation of the quantum-confinement energy versus both barrier thickness (N b ) and well width (N w ) have been derived. Our theoretical results are also shown to have excellent agreement with the available experimental photoluminescence data

In hierdie artikel word Hebreërs se inleidingsformules in besonderhede nagegaan om te bepaal wat die aard en inhoud van die Hebreërskrywer se verwysings na die tema van God se spraak in sy inleidingsformules is. Daar word onder andere bepaal dat Hebreërs 38 direkte aanhalings vanuit die Ou Testament bevat, dat die Hebreërskrywer, met slegs een uitsondering, elke inleidingsformule met ’n werkwoord van sêinlei, dat ’n Persoon van die Drie-eenheid in 34 van die 38 direkte aanhalings (± 89% die onderwerp en gevolglike Spreker van die Ou-Testamentiese woorde is, dat die Hebreërskrywer al drie Persone van die Drie-eenheid as God beskou, en dat die Hebreërskrywer oortuig is dat die Ou Testament geïnspireer is en God se geldige en relevante openbaring bly. The theme of God’s speech in Hebrews’ introduction formulae. Whilst the occurance and function of the Old Testament in research on Hebrews enjoys a lot of attention, this is not the case for the writer of Hebrews’ use of introduction formulae for his Old Testament quotations. The result is that up to date relatively few independent studies have been made on the writer of Hebrews’ theme of God’s speech in his introduction formulae. In this article the introduction formulae in Hebrews are researched in detail to determine the nature and content of the writer of Hebrews’ reference to the theme of God’s speech in his introduction formulae. Amongst other things it is determined that Hebrews has 38 direct quotations from the Old Testament, that with the exception of one

    This study used respondent-driven sampling to explore the effects of social support on HIV risk and protective factors among young males who have sex with males (YMSM) in Bangkok (N = 273) and Chiang Mai (N = 243), Thailand. It compared different measures of social support, including living situation, the proportion of family and friends to whom the respondent had disclosed their same-sex attraction, and scores on the multi-dimensional scale of perceived social support as predictors of two outcomes of interest-coerced first sex and HIV knowledge. Social support from family played a mediating role in both outcomes among YMSM in Bangkok but not those from Chiang Mai. Though social support from friends was also studied, it was less strongly associated with the outcomes of interest. The findings support interventions designed to leverage social support networks to increase HIV knowledge and decrease coerced first sex among YMSM. At the same time, they demonstrate that there is not a single risk or demographic profile encompassing all YMSM. Successful programs and policies will need to consider the specific attributes and social environment of YMSM in particular locations in order to effectively address HIV risks.

    One hundred and ninety five (195) brothel-based commercial sex workers (CSW) in Chiang Mai, Thailand, were screened for sexually transmitted disease (STD) between October 1994 and April 1995, prior to their enrollment in a multi-center comparative trial of the effectiveness of two strategies using male and female condoms. These CSW had a mean age of 22.2 (SD 4.3) years. Forty-seven per cent were Thai and 57.4 per cent had no formal education. Median duration of prostitution was 16 months and median cost for sexual service was 50 baht (US$ 2) per client. Ninety-four per cent of CSW reported always using condoms with clients. There were 63 (32.3%) CSW infected with at least one type of the STD screened. The prevalence of STD included chlamydial infection (16.9%), gonococcal infection (14.4%), condyloma accuminata (4.6%), moluscum contagiosum (2.6%) and trichomoniasis (1.0%). There was no statistically significant risk factor for STD found in this study. Despite an active programme for prevention of STD in CSW and the provision of free condoms, STD were diagnosed in one-third of the screened CSW in Chiang Mai. The programme needs to be strengthened by more intensive education and practice in the correct and consistent use of condoms and integrated with other STD prevention programmes.

    Starting in 1999, the University Cooperation Platform (UCP) implemented an exchange program of researchers and clinicians/physicists between the Christian-Albrechts-University Kiel in Germany and Chiang Mai University in Thailand, to initiate a sustainable base for long-term development of image-guided brachytherapy and in general for high-technology radiotherapy in Chiang Mai. A series of UCP protocols, based constructively on each other, were performed and evaluated at intermediate term follow-up. The first protocol, addressing computed tomography (CT)-optimized brachytherapy for advanced cervical cancer (n = 17), showed a significant reduction of D2cc for the bladder and sigmoid (p 80 Gy for bladder in only 17.2% versus 62.1% in conventional planning, and in rectum EQD2 > 75 Gy in 44.8% versus 79.3%, respectively. In conclusion, analyses revealed excellent results for the high-dose-rate IGBT in patients with advanced gynecological cancer both by using CT and MRI, and/or the combination with WP-IMRT. They also define MRI as gold standard for soft tissue assessment and to determine more accurately HR-CTV. The use of TAUS-guidance adds quality aspects to the "classical" conventional X-ray based planning, especially in terms of real-time measures and adequate soft tissue information, and may lower significantly the dose in OARs. The review of all UCP-results reconfirms the importance of the established program that will continue to operate with subsequent projects.

  14. Development of a NEHRP site classification map of Chiang Mai city, Thailand, based on shear-wave velocity using the MASW technique

    To account for site amplification and seismic hazard mapping, the shear-wave velocity (Vs) profile to a depth of 30 m (Vs (30)) is an important parameter and can be used to calculate the ground motion for specific site conditions. In this study, the near-surface Vs profiles of soils were collected at 44 sites in Chiang Mai city using the multi-channel analysis of surface-wave technique. The Vs of each tested location was average weighted to Vs (30) based on the National Earthquake Hazards Reduction Program (NEHRP) criteria. The average Vs (30) value of the alluvium soils was about 362 m s-1, which falls between NEHRP site classes C and D. The average Vs (30) values of flood plain, fluvial clay and natural levee soils (at 300, 299 and 311 m s-1, respectively) all equated to NEHRP class D. The colluvial deposits in the north-western part of the city were mainly composed of gravel, coarse sand and rock fragments, and were assigned to class C (average Vs (30) of 412 m s-1). Soils with lower Vs values will experience higher earthquake ground shaking than those of the bedrock. Accordingly the major part of Chiang Mai city may experience substantial ground shaking due to the amplification in the soft soils.

  15. Mapping Two-Dimensional Deformation Field Time-Series of Large Slope by Coupling DInSAR-SBAS with MAI-SBAS

    Full Text Available Mapping deformation field time-series, including vertical and horizontal motions, is vital for landslide monitoring and slope safety assessment. However, the conventional differential synthetic aperture radar interferometry (DInSAR technique can only detect the displacement component in the satellite-to-ground direction, i.e., line-of-sight (LOS direction displacement. To overcome this constraint, a new method was developed to obtain the displacement field time series of a slope by coupling DInSAR based small baseline subset approach (DInSAR-SBAS with multiple-aperture InSAR (MAI based small baseline subset approach (MAI-SBAS. This novel method has been applied to a set of 11 observations from the phased array type L-band synthetic aperture radar (PALSAR sensor onboard the advanced land observing satellite (ALOS, spanning from 2007 to 2011, of two large-scale north–south slopes of the largest Asian open-pit mine in the Northeast of China. The retrieved displacement time series showed that the proposed method can detect and measure the large displacements that occurred along the north–south direction, and the gradually changing two-dimensional displacement fields. Moreover, we verified this new method by comparing the displacement results to global positioning system (GPS measurements.

    Daily PM10 concentrations were measured at four sampling stations located in Chiang Mai and Lamphun provinces, Thailand. The sampling scheme was conducted during June 2005 to June 2006; every 3 days for 24 h in each sampling period. The result revealed that all stations shared the same pattern, in which the PM10 (particulate matters with diameter of less than 10 microm) concentration increased at the beginning of dry season (December) and reached its peak in March before decreasing by the end of April. The maximum PM10 concentration for each sampling station was in the range of 140-182 microg/m(3) which was 1.1-1.5 times higher than the Thai ambient air quality standard of 120 microg/m(3). This distinctly high concentration of PM10 in the dry season (Dec. 05-Mar. 06) was recognized as a unique seasonal pattern for the northern part of Thailand. PM10 concentration had a medium level of negative correlation (r = -0.696 to -0.635) with the visibility data. Comparing the maximum PM10 concentration detected at each sampling station to the permitted PM10 level of the national air quality standard, the warning visibility values for the PM10 pollution-watch system were determined as 10 km for Chiang Mai Province and 5 km for Lamphun Province. From the analysis of PM10 constituents, no component exceeded the national air quality standard. The total concentrations of PM10-bond polycyclic aromatic hydrocarbons (PAHs) are calculated in terms of total toxicity equivalent concentrations (TTECs) using the toxicity equivalent factors (TEFs) method. TTECs in Chiang Mai and Lamphun ambient air was found at a level comparable to those observed in Nagasaki, Bangkok and Rome and at a lower level than those reported at Copenhagen. The annual number of lung cancer cases for Chiang Mai and Lamphun Provinces was estimated at two cases/year which was lower than the number of cases in Bangkok (27 cases/year).

    Full Text Available BACKGROUND: People with low back pain (LBP with higher levels of external locus of control have a poorer prognosis and require greater improvements from active interventions in order to consider these interventions worthwhile. Whether locus of control levels differ between participants with LBP in a patient-health provider relationship and those waiting for treatment is unclear. OBJECTIVE: The aim was to investigate if differences in locus of control exist between participants with non-specific chronic LBP being treated (treatment group and those waiting treatment (control group. METHODS: 100 participants (50 per group with low back symptoms for at least three months for the current episode of LBP and aged between 18 and 60 years were recruited. Multidimensional health locus of control questionnaire (MHLC was used to collect their beliefs. Multiple linear regression adjusted for disability was used to compare health locus of control between both groups. Differences were described as mean differences and 95% confidence intervals. RESULTS: Treatment group scored higher for external locus of control and lower for internal locus of control than control group. Mean differences (95% confidence intervals were 2.7 points on possible 30-points difference (0.5 to 4.8 for external locus of control and -2.8 points (-5.4 to -0.1 for internal subscale. CONCLUSION: Health locus of control was found to be different between treatment and control groups. Participants being treated had higher external locus of control and lower internal locus of control than control group.CONTEXTUALIZAÇÃO: Pessoas com dor lombar com altos níveis de lócus de controle externo têm piores prognósticos e necessitam de melhores intervenções ativas, uma vez que elas são consideradas mais valiosas.

    The structures of a series of (TiSe 2 ) n (NbSe 2 ) m superlattices grown through controlled crystallization of designed multilayer reactants have been studied. X-ray diffraction of the data of the superlattices after crystallization show considerable preferred orientation, with the basal plane of the dichalcogenide structure parallel to the substrate to within 0.1 degree. Lattice refinement using the observed (00scr(l)) diffraction maxima yields lattice parameters along the c axis that are consistent with those expected based on the target superlattices and lattice parameters of the binary constituents. These (00scr(l)) diffraction data, however, contain no information about the crystalline structure in the ab plane of the superlattice associated with the preferred c-axis orientation. Off-specular x-ray diffraction (XRD), scanning electron microscopy, and scanning transmission x-ray microscopy (STXM) were used to explore the structure and homogeneity of the superlattices in the ab plane. XRD results rule out preferred long-range orientational order of the ab plane. Between grains, both the backscattered electron images and STXM images show grain domain structure in the ab plane with a characteristic grain domain size of approximately 50 μm. X-ray absorption microscopy in the STXM mode obtained at the Ti L 2,3 edge shows that the titanium in the superlattices is present as both octahedral Ti consistent with the TiSe 2 structure and metallic Ti. A comparison of the data obtained from these techniques highlights chemical information, which can be deduced on a submicrometer range from the space resolved spectra obtained using STXM. copyright 1997 American Institute of Physics

    The ferecrystals (PbSe){sub 1.14}(NbSe{sub 2}){sub n} are artificially layered materials consisting of n NbSe{sub 2} single-layers stacked alternately with atomic double layers of PbSe. NbSe{sub 2} is a transition metal dichalcogenide with interesting electrical properties such as superconductivity and charge density waves. The influence of turbostratic disorder, a random rotation between the NbSe{sub 2} and PbSe layers, on the superconducting transition temperature has been unknown so far. We investigate the structural and temperature-dependent electrical properties of the ferecrystals (PbSe){sub 1.14}(NbSe{sub 2}){sub n} by means of scanning transmission electron microscopy, X-ray diffraction, in-plane resistivity and Hall measurements and compare them to those of analogous non-disordered misfit layer compound (MLC) polymorphs. We observe a superconducting transition in the resistivity of the ferecrystals. The transition temperatures are reduced by up to 55 % with respect to the analogous MLC polymorphs. This indicates that turbostratic disorder substantially weakens the electron-phonon coupling in (PbSe){sub 1.14}(NbSe{sub 2}){sub n}. We discuss the results of the structural and electrical properties of the ferecrystals with respect to their MLC analogues and also with respect to ultra-thin NbSe{sub 2} layers.

    The selenium submicrotubes were directly prepared using Se powder as selenium source by microwave-assisted method. Field-emission scan electron microscopy (FESEM), transmission electron microscopy (TEM) and X-ray diffraction (XRD) were adopted to characterize the as-prepared products. The results of high-resolution transmission electron microscopy (HRTEM) and XRD pattern proved that the selenium submicrotubes were single crystalline in nature and [0 0 1] oriented. A possible growth mechanism of the selenium submicrotubes was proposed. The effects of the experimental conditions, such as alkaline concentration and solvent properties, on the morphology and dimension of the products have also been discussed

C'est le problème des moyens, des instruments et des incitations que doit désormais poser et résoudre l'action publique, les travaux des lauréats du " Prix Nobel d'économie " pouvant d'ailleurs se révéler fort utiles dans cette optique pratiqu...

    The Mais Médicos program was introduced in 2013 with the aim of reducing the shortage of doctors in priority regions and diminishing regional inequalities in health. One of the strategies has been to offer 3-year contracts for doctors to work in primary healthcare services in small towns, inland, rural, remote, and socially vulnerable areas. This report describes the program's implementation and the allocation of doctors to these target areas in 2014. To describe the provision of doctors in the first year of implementation, we compared the doctor-to-population ratio in the 5570 municipalities of Brazil before and after the program, based on the Federal Board of Medicine database (2013), and the official dataset provided by the Ministry of Health (2014). In its first public call (July 2013) 3511 municipalities joined the Mais Médicos program, requesting a total of 15 460 doctors; although the program prioritizes the recruitment of Brazilians, only 1096 nationals enrolled and were hired, together with 522 foreign doctors. As a consequence, an international cooperation agreement was set in place to recruit Cuban doctors. In 12 months the program recruited 14 462 doctors: 79.0% Cubans, 15.9% Brazilians and 5.1% of other nationalities, covering 93.5% of the doctors demanded; they were assigned to all the 3785 municipalities enrolled. The study reveals a major decrease in the number of municipalities with fewer than 0.1 doctors per thousand inhabitants, which dropped from 374 in 2013 to 95 in 2014 (75% reduction). Of the total, 294 doctors were sent to work in the country's 34 Indigenous Health Districts (100% coverage) and 3390 doctors were deployed in municipalities containing certified rural maroon communities (formed centuries ago by runaway slaves). After 1 year of implementation, the municipalities with maroon communities with less than 0.1 doctors per thousand inhabitants were reduced by 87% in the poorest north region. More than 30% of municipalities with

    Full Text Available Abstract Background High levels of depressive symptoms often occur among individuals that use or that are dependent on methamphetamine (MA. Thailand is currently experiencing an epidemic of MA use among youth. Understanding the nature of the relationship between depressive symptoms and MA use and identifying those most at risk can further understanding of prevention and treatment options for youth who use MA and present with depressive symptoms. Methods In 2011, we conducted a cross sectional epidemiologic study that examined associations between MA use and high levels of depressive symptoms among adolescents and young adults aged 14–29 living in Chiang Mai province, Thailand. A combination of cluster and systematic sampling was conducted to obtain a study sample of participants actively recruited in Chiang Mai province. Depressive symptoms were measured using a Thai translation of the Centers for Epidemiologic Studies Depression scale (CES-D. The independent variables measured reported lifetime and recent MA use within the past 3 months. Multivariate logistic regression models were used to assess associations between MA use and high levels of depressive symptoms. Results Approximately 19 % (n = 394 of the sample reported ever having consumed MA and 31 % (n = 124 of lifetime users reported recent MA use within the past 3 months. Recent MA use was associated with high levels of depressive symptoms (aPOR recent use: 2.60, 95 % CI: 1.20, 5.63. Conclusions This is one of the first studies to examine the association between MA use and high levels of depressive symptoms in a general Thai population. The odds of having high levels of depressive symptoms was significantly greater among recent MA users compared to non-users. These findings support the need for policies, programs and interventions to prevent and treat depressive symptoms presenting among MA using Thai adolescents and young adults in rural Chiang Mai province, Thailand to

Furthermore, additional research is needed to

    distribuídas em delineamento em blocos casualisados com 6 tratamentos, 10 repetições e 8 aves por unidade experimental. Os tratamentos consistiram de ração basal deficiente em metionina mais cistina (0,65%, com 19,6% de proteína bruta e 2800 kcal de energia metabolizável/kg de ração, suplementada com seis níveis de DL-metionina 98% (0,116; 0,167; 0,218; 0,269; 0,320 e 0,371%, correspondendo à relação metionina mais cistina com lisina de 0,65; 0,70; 0,75; 0,80; 0,85 e 0,90, sendo a lisina digestível fixada no nível sub ótimo de 1,00. Os parâmetros estudados foram: consumo de ração, produção de ovos por ave dia, produção de ovos por ave alojada, produção de ovos comercializáveis, peso do ovo, massa de ovos, conversão alimentar por massa de ovos, conversão alimentar por dúzia de ovos, viabilidade das aves, peso dos componentes dos ovos (gema, albúmen e casca, porcentagem dos componentes dos ovos, diâmetro e altura dos ovos e gravidade específica. Observou-se efeito linear crescente para consumo de ração, diâmetro dos ovos, peso da casca e porcentagem de gema. Para porcentagem de casca foi observado efeito linear decrescente. Para o peso dos ovos o melhor ajuste foi obtido com a utilização do modelo Linear Response Plateau. Foi verificado efeito quadrático para a massa de ovos, conversão alimentar por massa de ovos, produção de ovos por ave dia, produção de ovos por ave alojada, peso da gema, peso do albúmen e altura dos ovos. A relação metionina mais cistina com lisina de 0,84 que corresponde ao consumo de 221,0 mg/ave/dia de metionina + cistina proporciona melhor desempenho e satisfatória qualidade de ovo de codornas japonesas.
