The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t.

Levando-se em consideração que a natação é um exercício excelente para a saúde e tem sido um esporte preferido por pessoas de várias idades de ambos os sexos; e que a massa líquida, contida em tanques, pode veicular doenças, procurou-se estudar as condições sanitárias de algumas piscinas públicas e particulares da Cidade de Araraquara, SP (Brasil). em 36 tomadas de amostras de águas de piscinas públicas e 22 de piscinas particulares, constatou-se que, embora recebendo tratamento específico, elas não mantêm os níveis de cloro suficiente para impedir a proliferação de bactérias, algumas das quais perigosas para a saúde dos freqüentadores. Verificou-se que os níveis de cloretos estavam altos, indicando contaminação das águas por urina ou mesmo suor do corpo, e concluiu-se que o banhista deveria receber instruções a respeito.

Background - Hidrocystomas ecrine and apocrine may be observed in the eyelids. Objective - The purpose of this study was to observe the occurrence of eyelid hidrocystoma (eccrine or apocrine), as well as the relation between clinical and histopathological diagnosis. Patients and Methods - 42 patients were selected, with a total of 52 lesions, attended between January 1990 to April 1999, at the Botucatu Medical School, with diagnosis of hidrocystoma confirmed by histopathology diagnosis. Result - Hidrocystoma occurred in 0.07% of patients undergoing lesion removal during this period. Eccrine and the apocrine hidrocystoma were frequently observed in female patients, aged over 40 years. The clinical picture ranged from about 1 to 5 years. The lesions were mainly located in the lower eyelid and presented as a single lesion. The clinical diagnosis agreed with the histopathological diagnosis in 67.31% of the apocrine hidrocystomas, and 9.62% of the eccrine hidrocystomas. Conclusions - Apocrine hidrocystoma was the most frequently observed eyelid hidrocystoma. The correlation between clinical and histopathological diagnosis was higher for apocrine hidrocystomas.

Nasal polyps are a clinical sign of alert for investigating Cystic Fibrosis (CF). Aims: To study the incidence of nasal polyps in children and adolescents with cystic fibrosis, its possible association with age, gender, clinical manifestations, genotype and sweat chlorine level, and its evolution with topical steroid therapy. Methods: Clinical symptoms, sweat chlorine level and genotype were studied in 23 cystic fibrosis patients. Nasal polyps were diagnosed by nasal endoscopy and treated with topical steroids during 6 months, followed by a second nasal endoscopy. Fisher test was used for statistical analysis. Results: Nasal polyps were found in 39.1% of the patients (five bilateral, four unilateral), all older than six years, recurrent pneumonia in 82.6%, pancreatic insufficiency in 87% and malnutrition in 74%. No association was seen between nasal polyps and sweat chlorine level, genotype, clinical sings of severity and nasal symptoms. Seven patients improved in their nasal polyps with topical steroids, six showed complete resolution. Conclusion: The study showed a high incidence of nasal polyps in older children, who span the entire range of clinical severity, even in the absence of clinical nasal symptoms. Topical steroid therapy showed good results. An interaction among pediatricians and otolaryngologists is necessary for diagnosis and follow-up. 2008 © Revista Brasileira de Otorrinolaringologia.

Considering the lack of detailed information about the morphology of paca, which is the second largest rodent of Brazilian's fauna, with excellent meat quality and, due to the importance of the common integument, we described the morphology, ultrastructure and morphometry of the skin of eight pacas (Cuniculus paca), males and females, through comparative analysis of skin's segments of the cervical, dorsal and medial carpal portions. Macroscopic characteristics of the coat were studied. Part of the segments of cutaneous regions was analyzed by light microscopy, and the other part by scanning electron microscopy. We measured the thickness of dermis, epidermis, stratum corneum, the profiles of the collagen fibers of reticular dermis and the area of filled sebaceous gland cells. The results were analyzed by descriptive statistics and T test (p<0.001). The color of the coat is reddish brown with bristles arranged in groups. The architecture of the skin and skin appendages resembles those of mammals in general, although there are no sweat glands. According to the morphometric analysis, this study shows differences of the skin architecture between male and female pacas and also between various body regions in the same animal.

Abstract: In the past few years, tribocorrosion has become a focus of research because of its relevance in terms of the future in-service degradation mechanisms of materials. In the particular case of decorative coatings, tribocorrosion is certainly one of the most important issues, and sweat corrosion and human contact wear are two other factors that may act as material selection tools. Thus, the current study aimed to investigate the tribocorrosion behavior of a new class of thin films, the Ti-C-O-N system, which is being developed to be used as a surface decorative material due to its relatively dark appearance. The films were prepared by reactive magnetron sputtering. The influence of the structural features on the tribocorrosion behavior is discussed. Crown Copyright © 2013.

Esta dissertação é um estudo sobre as ações em torno do desenvolvimento sustentável e de políticas não agrícolas para as pequenas populações rurais, a partir dos anos 80 e 90. Com a interiorização das políticas, o Estado se torna mais presente nas regiões interioranas redimensionando o mundo rural e suas dinâmicas locais. Neste sentido, um novo rural emerge com as ações políticas que chegam às populações mais distantes expondo o modo de vida a novas situações. Este estudo objetivou analisar as mudanças na organização social e econômica dos moradores da localidade rural de Vila Alencar da Reserva de Desenvolvimento Sustentável Mamirauá (RDSM), no estado do Amazonas, decorrentes da criação de uma reserva de desenvolvimento sustentável (RDS) e das ações institucionalizadas por políticas de Estado. A análise teórica foi fundamentada na noção de habitus e do campo socioambiental da Reserva Mamirauá. Realizaram-se também análises entre as famílias a partir do tempo de união conjugal, com a finalidade de identificar as mudanças ocorridas entre duas gerações familiares. Constatou-se neste estudo que a organização familiar em Vila Alencar se desenvolve levando em consideração as práticas locais e também participam das ações intervencionistas através das políticas sociais por meio do Programa Bolsa Família, das aposentadorias rurais e das atividades em torno do manejo sustentável dos recursos naturais, que estão em sua maioria associadas ao manejo de ecoturismo, a exemplo, da prestação de serviços como guia turístico, auxiliar de cozinha, copeira e carpintaria para a pousada de ecoturismo da RDSM. A combinação de atividades agrícolas, nãoagrícolas e a complementação de renda por benefícios sociais assumem papel importante na composição da renda familiar, o que traz novas perspectivas à reprodução social. O estudo mostrou que as políticas de desenvolvimento sustentável bem como as políticas de benefícios sociais tornam favorável à organização familiar das localidades rurais as características de feições modernizadoras e atrativas do conforto urbano, sobretudo pela expectativa da compra de uma casa na cidade e de melhores condições de qualificação aos filhos para prosperarem em alguma profissão. Aos jovens são delegadas outras responsabilidades que não se inserem exclusivamente no contexto produtivo do trabalho familiar.

The search for predictions of species diversity across environmental gradients has challenged ecologists for decades. The humped-back model (HBM) suggests that plant diversity peaks at intermediate productivity; at low productivity few species can tolerate the environmental stresses, and at high productivity a few highly competitive species dominate. Over time the HBM has become increasingly controversial, and recent studies claim to have refuted it. Here, by using data from coordinated surveys conducted throughout grasslands worldwide and comprising a wide range of site productivities, we provide evidence in support of the HBM pattern at both global and regional extents. The relationships described here provide a foundation for further research into the local, landscape, and historical factors that maintain biodiversity.
