No presente estudo foi avaliada a distribuição espacial do percentil 75 da precipitação decendial para o Estado de São Paulo, utilizando-se um total de 136 postos pluviométricos com séries acima de 27 anos de registros. Em um estágio preliminar os valores dos percentis 75 da precipitação decendial foram georeferenciados, permitindo a utilização de técnicas da geoestatística para proceder à interpolação dos dados. Modelos experimentais de semivariogramas padronizados foram obtidos, utilizando-se a variância amostral como fator de escalonamento, permitindo a verificação de proporcionalidade entre os modelos e agrupando-os sob a mesma tendência. O modelo teórico exponencial foi o que melhor se ajustou aos semivariogramas experimentais, seguido pelo modelo esférico. Os parâmetros estimados para os modelos, efeito pepita, patamar e alcance foram utilizados para a realização da krigagem e confecção dos mapas de isolinhas. A distribuição espacial dos percentis 75 da precipitação decendial reflete o comportamento da circulação atmosférica no Estado, apresentando alta variabilidade. As regiões oeste , sudoeste e noroeste apresentaram as menores intensidades de precipitação e foram variáveis de acordo com os níveis temporais na primavera. A região litorânea apresentou as maiores intensidades de precipitação para quase todos os níveis temporais estudados, diferenciando-se das demais regiões do Estado. A exceção foi à região nordeste no final da primavera que apresentou valores de intensidades maiores do que os registrados no litoral. A faixa litorânea apresentou comportamento homogêneo, detectado pelo forte agrupamento das isolinhas em quase todos os decêndios analisados.

Applicability of management theories to developing organizationations and structured process for managing change and create an environment for innovation and adaptation. The study skills resources focus described information science area and your essencial function building a knowledge society. The work process administration involves organizational environment. When working to resolve conflict, it is important to solve parties in personal conflict for success of the organization. For theory of human relations, informal groups influence in the archive workplace. Thus the aim of this paper is to proposed analyse the influence human relations theory for the process archive management. That methodology will follow the recommendation archive university case study. The data analysis for the current case study follows focus group. The conduct the case study was guided by three phases: Motivational elements, the individual and influence behavior, integration of the formal and informal organization. Employees May Be the Key to Success for O rganizations and develop the conclusions and recommendations portray motivation and a good working environment stood out the factors that employees develop skills and competencies. Organizational behavior that is present in forms of rewards, recognition, social man and informal groups. The nature of research contribute to the process archive management. Development and suggested that the findings of the analysis are applied to a larger structure of archive organization, as well as public archive case study.

The nickel alloys have a chemical composition with high tenor of alloy elements which are responsible for the material's mechanical and thermal properties, but also are the main causative of problems during the machining, making the process difficult. The objective of this work is the study of the machining by external cylindrical turning of the nickel based alloy Nimonic 80A, seeking the machining optimization of this alloy, seeking the best condition of lubricant fluid use, providing real increases of productivity without the need of investments in new production means. Besides, the results of this work should offer more detailed information regarding the behavior of this alloy in relation to machining by turning. The machining experiences were accomplished in a specimen of the nickel alloy, considering the machining parameters: cutting speed (75 and 90 m/min), cutting depth (0,8 mm) and feed rate (0,15 and 0,18 mm/v). The valuations were accomplished in a CNC lathe and tools with of hard metal inserts. After each stage of the turning the measures of the cutting length were accomplished, of the waste of the tools through a magnifying glass (8x) and the roughness of the specimen evaluated in each phase of the process, with the aid of a portable roughness meter. Through light optical microscopy it was possible to observe the wear of the cutting tools for each appraised condition. The roughness values, Ra and Ry, for the appraised conditions were always superiors to the theoretical values. After analysis of the results it was possible to end that, the best acting for this work strip tested it was obtained for ap=0,8mm: f=0,15mm/rev and VC=75m/min, what resulted in a larger cutting length (1811 m)

Large motor dysfunctions are observed in older adults with the age advance. Parkinson’s disease (PD) patients have motor deficits to perform daily living activities. To raise from a chair, a daily task necessary to live independently, requires both large muscle recruitment and large joint range of motion to achieve the vertical position safely. Normally, we initiate gait after raise from a chair. The aim of this study was to analyze the PD patients’ behavior when rising from a chair and initiating gait and to compare it according to the age advance. In order to do that, 23 PD patients (66.61±7.64 years old) were distributed in three age groups: Young group, between 51 and 60 years of age (n=7); intermediary group, between 61 and 70 years of age (n=7); and elderly group, over 70 years of age (n=9). There were no statistical differences among groups either for the disease evolution stage or for it compromising. The task was to stand from a chair and to initiate gait forward in three attempts. The dependent variables were: spatial and temporal (first step length and duration, and stride length, duration and velocity) and angular (flexion and extension of head, shoulder, hip, knee, and ankle). The motion of standing from a chair was divided in two phases. The data was statistically treated by means of Analyses of Variance with group as the only factor. The Scheffé’s post hoc test was used to localize differences among groups and the significance level was adjusted to p≤0.017. There were statistical differences for stride...(Complete abstract click electronic access below)

Os Medicamentos Isentos de Prescrição (MIPs) são de venda livre que têm como propósito tratar sintomas e distúrbios menores, sendo responsáveis pela movimentação de bilhões de dólares a cada ano mundialmente. É permitida a veiculação de propagandas direta ao consumidor, não sendo obrigatória a apresentação da prescrição. A disponibilidade e o consumo de MIPs podem impactar a saúde, economia e a promoção do uso racional de medicamentos, portanto se faz necessário compreender o comportamento e as motivações dos consumidores pelos MIPs e a prática da automedicação. Para tanto, conduziu-se um estudo entre março e junho de 2014 por meio de entrevistas com perguntas abertas referentes a classes terapêuticas adquiridas para automedicação, frequência com que os consumidores compraram MIPs e se automedicaram, os problemas de saúde que os motivaram a se automedicarem e a comprarem MIPs e à prática da automedicação. Foram entrevistados 47 consumidores entre 18 e 70 anos residentes em Araraquara/SP. A indicação familiar é o fator de influência mais recorrente (14), seguida pela indicação do balconista da drogaria (11) e amigos (6). A classe de MIPs mais consumida pelos entrevistados é a de analgésicos, que está relacionada com a ocorrência de dores de cabeça e musculares, sendo que a compra de MIPs ocorre, no mínimo, uma vez por mês. As motivações para a compra são principalmente o preço (33) seguido da marca (30). A automedicação ocorre também para o alívio de dores e a maioria alegou saber o conceito da automedicação porém, ainda assim, afirmou administrar por conta própria medicamentos MIPs e/ou sujeitos a prescrições, sem orientação de um profissional de saúde.

The industry generally has sought materials with high mechanical resistance, low density, thermal stability and corrosion resistance. In the aerospace industry, for example, the use of aluminum alloys, such as Al 2024-T351 and Al 7075-T7351, have become essential. However, the use of these materials often do not resulted in a satisfactory performance of the component, since the presence of cracks can cause total rupture of the component, even with a tension below the yield stress of the material, unexpectedly. In this work, these aluminum alloys were analyzed and samples were modeled by the finite element method. Moreover, in the models were applied two different types of cracks, central and edge crack, a vertical force was applied to result in a tension 70% of the yield stress of the material analyzed. Through stress asymptotic distribution in the region near the crack tip were calculated the values of the stress intensity factors for each crack length, after the stress intensity factors characterized were compared graphically with the values of fracture toughness found in the available literature
