Produção de partículas secundárias em reações de “spallation” induzidas por prótons

Cosmic radiation has been identi ed as one of the main hazard to crew, aircraft and sensitive equipments involved in long-term missions and even high-altitude commercial ights. Generally, shields are used in spatial units to avoid excessive exposure, by holding the incident radiation. Unfortunatelly, shielding in space is problematic, especially when high-energy cosmic particles are considered, due to the production of large number of secondary particles, mainly neutrons, protons and alpha particles, caused by spallation reactions and quasi-elastic processes of the corpuscular radiation with the shield. Good parameters for checking the secondary particle production at target material are diferential cross section and energy deposited in the shield. Addition experiments, some computer codes based on Monte Carlo method show themselves a suitable tool to calculate shield parameters, due to have evaluated nuclear data libraries implemented on the algorithm. In view of this, the aim of this work is determining the parameters evaluated in shielding materials, by using MCNPX code, who shows good agreement with experimental data from literature. Among the materials, Aluminium had lower emission and production of secondary particles

Mortalidade Materna: uma abordagem atualizada

Purpose: to review literature, highlighting current aspects of maternal mortality.  Method: research initiated through electronic data base PubMed [http:// www.ncbi.nlm.nih.gov/pubmed], limited to the last 10 years. The selected cases which related to pre-defined aspects of interest to the study, such as vulnerable population, risk factors, causes, difficulties in obtaining data, preventive measures e new approaches to the problem, among them, ‘near misses’ and severe maternal morbidity.  Results: maternal death is directly related to the quality of life of the population, with relevant disparities among the different social economic areas. Although maternal mortality is the proper indicator to the female population health, its numbers are presented in unrealistic manners due to the difficulties in identifying the cases through death certificates. Preventive measures associated to early and adequate diagnose and treatment are benefic factors in decreasing those maternal deaths. Apart from these, identification and classification of ‘near misses’ and maternal morbidity are featured in the contemporary approach to the issue.  Final considerations: In spite of advanced technology and recognition of preventive measures, a large number of women die daily due to complications in the pregnancy and puerperal cycle. To decrease such tragedy political, social and economical commitment to Health is necessary, in order to promote the needed reforms in the assistance of such cycle.

Altas habilidades ou superdotação: um estudo em uma Diretoria de Ensino da rede estadual paulista

Special Education includes gifted students. There is a lack of resources and information for identification and care of such students. They were research objectives map students with giftedness characteristic in Elementary and Middle School in Bauru/SP, as well as verify what teachers know about the issue and if they know how to work with such students in their classrooms. This qualitative, quantitative and descriptive research was structured in three stages. Step A: an observation guide of gifted children, Guia de observação de crianças dotadas e talentosas. Step B: True or False questions on the subject. Step C, field diary. Two hundred and thirty one classes from 24 schools were evaluated and 477 students were identified with giftedness characteristic in at least one of six possible areas. Three hundred and one students were in Elementary School and 176 were in Middle School. In Step B, 280 teachers from 26 schools were part of this study and it is confirmed that they have theoretical knowledge on the subject because the number of hits on the main concepts (based on the literature) was superior to the number of misses. A 4th grade classroom, with a gifted girl, was observed in step C. It was found that the teacher pedagogical practice and the resources used are not different from the ones used with other students. Thus, it appears that the student has not received the curricular adaptations to assist her developing skills

A 'Relação' de Jacinto de Carvalho (1719), um texto inédito de etnografia amazônica

Depois de trabalhar por treze anos nas missões da Amazônia, o jesuíta português Jacinto de Carvalho (1677-1744) enviou ao superior da ordem uma relação descritiva do país e de alguns costumes da população indígena. Essa é a principal fonte etno-histórica da Amazônia na primeira metade do século XVIII, mas é conhecida somente por meio de uma tradução italiana coeva, até hoje inédita. Os trechos de interesse etnográfico foram aqui vertidos à língua portuguesa, precedidos de estudo.

Construção de perfis de temperatura a partir de dados de Satélites,Climatologia e dados in situ

A aquisição de dados da estrutura termohalina dos oceanos sempre foi limitada pelo alto custo das missões oceanográficas. Sistemas de amostragem in situ menos dispendiosos, como o lançamento de XBTs por navios de oportunidade, a utilização de bóias de deriva, e mais recentemente, de sistemas de observação autõnomos como gliders e flutuadores Argo, foram concebidos como alternativas aos cruzeiros. Estes sistemas são capazes de cobrir vastas porções oceanicas e de fornecer grande quantidade de medições, porem seus dados nem sempre estão disponíveis ou mesmo são adequados `a resolução de um determinado problema ou ao estudo de um fenômeno em questão, devido principalmente à sua falta de sinopticidade e/ou cobertura espacial irregular. Sensores orbitais provaram ser valiosos e comparativamente possuem excelente periodicidade e cobertura espacial, mas suas observações são limitadas apenas à superfície dos oceanos. Assim, a capacidade de se inferir com boa precisão a estrutura termohalina de feições oceanográficas à partir de uma amostragem reduzida e/ou utilizando medições¸ indiretas é desejável e vem sido aprimorada em diversos trabalhos. Métodos clássicos incluem o desenvolvimento de modelos de feição pelo ajuste de curvas paramétricas (e.g. GANGOPADHYAY et al., 1997; CHU et al., 1999) e a reconstrução de perfis utilizando modos EOF (e.g. CARNES et al., 1990; AGARWAL et al., 2007)
