Análise da relação instituição escolar e família na revista Nova Escola

O trabalho buscou investigar como uma revista de grande circulação entre os professores do ensino básico trata a questão da relação entre escolafamília. O motivo pelo qual buscamos pesquisar sobre o assunto é o fato dos professores recorrerem a este tipo de material, que acaba normatizando a sua prática. No entanto, será esta leitura adequada? Qual a real contribuição da revista? Fazendo uma comparação com a literatura científica o que poderemos constatar? Como metodologia foi feita uma análise documental das Revistas Nova Escola durante os últimos 5 anos, do período de junho de 2006 à junho de 2010. Analisou-se todas as revistas correspondente ao período indicado e selecionado somente os artigos que falavam sobre a relação escola-família. Posteriormente foi feita uma análise quantitativa e qualitativa dos artigos através da Análise de Conteúdo dos mesmos, analisando os dados à luz do embasamento teórico sobre o assunto, fazendo uma comparação com a literatura. Observou-se com a pesquisa que embora a quantidade de reportagens abordando o assunto família-escola fosse em pequena quantidade, eram muito coerentes e continham embasamentos teóricos indiretos.

Futebol brasileiro: uma análise comparativa das fórmulas de disputa do campeonato brasileiro da série A nos últimos 15 anos (1995-2010)

In Brazil, the football is more than just a sport, it's a passion and part of country's DNA almost a century ago. By this prerogative the club national championship, nowadays known as Brazilian Championship and organized by Brazilian Football Confederation, it is a mark in this modality. During the soccer history, were made several changes of nomenclature, rules and dispute mode, that generated many controversies, contributing for discussing about credibility of the championship. There were many changes about dispute mode, alternating the mixed mode (eliminatory + classificatory and vice versa) and a dispute mode based on classification. This research aimed to described and to analyzed the changes that have occurred in dispute types of the Brazilian Championship, series A, in the last 15 years (1995 to 2010). It was analyzed each edition, with data like average of public, matches and participants number, period that the championship was conducted, beyond the dispute mode. In the last 15 years, have been used five different types and it was observed that the current mode to consecutive points is the most appropriate, because this mode showed the best public average, greater coherence to elect the competition champion and this mode also encouraged the clubs about planning, organization and professional management. This issues contributed to a significant improvement in quality of Championship

Valores e atitudes: uma análise de artigos na educação física escolar

É notória a crescente preocupação com os aspectos éticos e morais quando se refere à Educação no Brasil. Não poderia ser diferente com a Educação Física escolar, já que se trata de um componente curricular obrigatório dentro da Educação Básica. Apesar da tentativa crescente de conscientização da importância dos valores enquanto conteúdos explícitos na educação formal, não se têm claro quais deveriam fazer parte do planejamento dos professores. Esta pesquisa teve como objetivo geral realizar um levantamento de artigos em periódicos científicos da Educação Física que abordassem valores e atitudes presentes na disciplina. Em outras palavras buscou-se mapear e analisar quais valores e atitudes são esses na Educação Física, no contexto escolar. Para a seleção dos periódicos científicos analisados, foram seguidos os seguintes critérios: revistas específicas da Educação Física; trabalhos propostos à publicação julgados por pareceristas; acesso tanto ao resumo quanto ao trabalho na íntegra; acesso a todos os números das revistas publicados entre os anos de 1998 e 2007. A análise quantitativa constatou que o número de artigos científicos que abordaram o tema valores e atitudes nos últimos dez anos foi pequeno. Entre aproximadamente 1000 artigos analisados, foram localizados apenas 40 artigos. Apesar do número reduzido de artigos, observou-se uma tendência no aumento das publicações a partir de 2002, seguindo tendência da área da Educação. Valores como alteridade, socialização, voluntariedade, estética e saúde apareceram nos artigos analisados. O tema de valores e atitudes é discutido na produção científica da Educação Física, embora ainda de forma incipiente, e os temas analisados são bastante abrangentes.

Estudo da fragilização ao revenido em aço liga de 2,25CR-1MO através do ensaio de indentificação instrumentada

2,25Cr-1Mo alloy steels are widely used in petrochemical plant equipments working in high temperature conditions because of their good mechanical proprieties in these conditions. Although, when exposed for a long time at high temperature, in the rage of 343 °C to 593 °C, may present the temper embrittlement phenomenon. The component named stripper of assembly converter of fluid catalytic cracking unit (UFCC) of studied plant is manufactured using this material, which is subject to temper embrittlement. The phenomenon of temper embrittlement refers to progressive lose of toughness, making the material brittle. With embrittlement, equipaments manufactured with this material are under risks to suffer brittle fracture in the cool down and start-up situations of them, which can cause catastrophic failures. By this reason, this research studies presence of temper ebrittlement phenomenon on this material. To verify the toughness of the material is conventionally used charpy V-notch test. However, this test requires the removing of samples of the material to make specimens. This fact becomes critical when talk about structural components of an equipment. So, this research also studies a non-destructive test that can be executes in-situ, known as instrumented indentation, as an alternative detection of the phenomenon at the component stripper, by comparative of the mechanical proprieties obtained by conventional tests in similar samples

Desenvolvimento de tratamentos térmicos visando ganhos magnéticos em aços com ultra baixa concentração de carbono

The relationship between the microstructure and the magnetic properties of soft magnetic materials, have been studied by different researchers who seek to employ electrical systems, increasing their life span and reduce their energy consumption. Following this same line the Brazilian Synchrotron Light Laboratory developed a new synchrotron light source, the Sirius, where magnetic materials with high magnetic permeability values are being studied for use in accelerator dipoles. The low carbon steel is a ferromagnetic material that has a great relationship between cost and magnetic permeability. Aiming to raise the values of permeability of the material, heat treatments were done and evaluated the magnetic properties, microstructure and mechanical properties to correlate them. It was noted that the thermal annealing were the most effective, and the annealing performed with a small time threshold, which only phenomenon observed was the primary recrystallisation, was the most elevated values of magnetic permeability of the material, due to the average grain size ideal achieved. The heat treatments do not guide the magnetic domains of the material and not influence the mechanical properties of the material due to lack of carbon in the microstructure. The annealing treatments were shown to be an alternative to raising the values of the magnetic permeability of the material and facilitate the implementation of ultra low carbon steel in the dipoles of Sirius

Avaliação cinemática em cães: revisão

Kinematics is the geometry of motion, including displacement, speed and acceleration, without considering the forces acting over a body. The use of kinematics is still very limited when we are evaluating dogs because of the high cost of the equipment, but the information obtained is objective and precise, what is essential for a trustful evaluation. Taking all this into consideration, this evaluation will describe some researches that used the method, specifying the final objective for each of them. By this analysis, we can conclude that kinematic studies, according to the characteristics of dog races, are necessary to explain how body structure and conformance may affect the function. Besides that, according to normative patterns of a population it is possible to study some diseases and treatment evolution

Desenvolvimento, otimização e caracterização física de um novo sistema multi-sensores de Biosusceptometria de Corrente Alternada (BAC) para obtenção de imagens biomagnéticas

A novel AC Biosusceptometry (ACB) system with thirteen sensors it was implemented and characterized in vitro using magnetic phantoms. The system presenting coils in a coaxial arrangement with one pair of excitation coil outside and thirteen pairs of detection coils inside. A first-order gradiometric configuration was utilized for optimal detection of magnetic signals. Several physical parameters such as baseline, number of turns, excitation field and diameters were studied for improvement of the signal/noise ratio. This system exhibits an enhanced sensitivity and spatial resolution, due to the higher density of sensors/area. In the future those characteristics will turn possible to obtain images of magnetic marker or tracer in the gastrointestinal tract focusing on physiological and pharmaceutical studies. ACB emerged due to its interesting nature, noninvasiveness and low cost to investigate gastrointestinal parameters and this system can contribute for more accurate interpretation of biomedical signals and images

Fidelidade composicional de assembléias de braquiópodes (Rhynconelliformea) na plataforma e talude continental: implicações paleontológicas e geológicas

This paper deals with the Compositional Fidelity of the brachiopods assemblages, dominated by Bouchardia rosea, on the outer shelf and continental slope along São Paulo State. Samples were obtained during the Revizee-Score-Sul-Benthos program. The sampled stations are in sites as depth as 90 to 600 meters, along the outer continental shelf, the shelf break and the top of continental slope. The fidelity estimates were obtained directly from the comparisons between living biota and dead shells, from the same collecting stations. Data come from 66 sampling stations, and the vast majority of the Bouchardia rosea individuals collected (n=2393) were dead (n = 2342, 97.9%). Only 51 individuals were collected alive. When pooling the data from all collecting stations the dead/live frequency is of 2,1% only. The occurrences of Bouchardia rosea shells in siliciclastic bottoms are reduced and living individuals were not found on this type of bottom, at least during the sampling program. These results suggest low compositional fidelity (live-dead) or high compositional mismatch, pointing to a recent decrease in this specie population. The low compositional fidelity of the Bouchardia rosea assemblages in outer shelf sites may be due to changes in seawater temperature, nutrient availability and population history. All these issues must be investigated in the near future
