The aim of this approach is to describe the design and construction of a low-cost automated water sampler prototype. In recent years, there is an increasing need on the use of automated equipments for hydro climatic variables to be use in urban and rural environments. Such devices are always used to provide measured information which is of crucial importance on the development of water resources strategies at watershed scale. Actually, many research and water public institutions have been using these kinds of equipments. In most of the cases, automated equipments are expensive and need to be imported, generating a situation of technologic dependency. The prototype is based on an electronic system which controls a peristaltic pump functioning, five solenoid valves and an ultrasonic sensor connected to a datalloger. An interface with the user allows communication with a PC, when the equipment functioning parameters can be provided. The equipment has a hydraulic module composed by a 12V peristaltic pump connected to a distribution circuit composed by five solenoid valves, one of them being used to clean the circuit before each sampling procedure. Samples are collected by four 1.95 polyethylene bottles. The sampler body was made of acrylic material, with a cylindrical shape, and dimensions 0.72 m and 0.38 m height and diameter, respectively. The weight of the equipment without samples is approximately 15 kg, which infers to its portability. The prototype development total cost budget was approximately US$ 1,560.00. Laboratory tests aimed to evaluate the equipment performance and functioning demonstrated satisfactory results

Pastorais, Bailes Pastoris, Festa da Lapinha, Terno de Reis, Pastor, Pastoril Religioso ou Profano... Pastoris do Norte e Nordeste brasileiro. M ário de Andrade designou-o de Pastoril, folguedo de origem ibérica, tendo sua raiz primeira nos villancico. Considerando que o Pastoril é um folguedo popular, porque nele seus participantes engajam sua vida pessoal, sua cultura e suas influências, revelando modos de ser e compreender, que são interiorizados pelos brincantes a partir da vivência de seu contexto social múltiplo e de diferentes sentidos, é que situamos esse folguedo no mundo vivido fenomenológico. A investigação é de natureza fenomenológica, elucidando os elementos citados como cenário do vivido e do sensível. O presente trabalho tem como objetivo refletir sobre a compreensão de corpo encontrado nos pastoris norteriograndenses

Esta pesquisa objetiva identifi car as novas confi gurações de corpo advindas da interconexão entre Dança e Tecnologia, bem como compreender de que maneiras essas confi - gurações se aproximam e contribuem para a compreensão de corpo na Educação Física. O recurso metodológico é a análise de imagens dos vídeos de dança: Digital Brazuca e Corpo Aberto. Os vídeos analisados apontam para um repertório de saberes, que podem ser problematizados na área, e contribuem para reconfi gurar a relação homem/ambiente. Nesse sentido, promovem a plasticidade e a polissemia de relações entre o carbono e o silício, e desenham outras formas de compressão do corpo que incluem a complexidade, a incerteza, a reversibilidade e a descoberta

The present study compare the size of the corpora pedunculata (mushroom bodies) of Exomalopsis aureopilosa a quasi-social specie and Apis mellifera a eusocial specie of bees. The aim was to correlate the developmental degree of such structures with the behavior complexity. The results show that the female specimens of both species have the corpora pedunculata with same relative size. However the area occupied by the neurones cellular bodies (glomeruli) is greater in the workers of A. mellifera. In other way in E. aureopilosa the total size of the corpora pedunculata is larger in females, but the glomeruli area is relatively larger in the male.

Type-1 diabetes patients suffer from frequent episodes of acidosis caused by an increased fatty acid metabolism and consequently increased plasma level of acetoacetate (AcAc) and β-hydroxybutyrate (β-HOB). This article describes a study of the effects of pathological concentrations of AcAc and β-HOB on lipoperoxidation, cell viability and the release of the CXCL8 (IL-8) cytokine by activated neutrophils. Neutrophils from healthy donors were isolated by density gradient (Histopaque® 1077/1119) and incubated with the ketone bodies. Lipoperoxidation was determined as thiobarbituric acid reactive substances (TBARS). The cell viability was evaluated by the release of intracellular lactate dehydrogenase. The release of CXCL8 was measured by ELISA in a 24-h culture of opsonized zymosan-stimulated neutrophils. AcAc, but not β-HOB, provoked a dose-dependent increase in the neutrophil membrane lipoperoxidation (p<0.05; r =0.9915). In the cytotoxicity assay, a dose-dependent release of LDH was observed when the neutrophils were incubated with AcAc in concentrations up to 40 mM (p<0.05). β-HOB was devoid of effect. The release of CXCL8 was inhibited by AcAc and β-HOB in a dose-dependent manner. In conclusion, these results suggest that the accumulation of ketone bodies in diabetic patients could be involved in their usually increased susceptibility to infection.
