Preparação de substratos de carbeto de silício para fins aeroespaciais

This conclusion thesis has the objective of produce substrates of Silicon Carbide from the powder of SiC for aerospace use. The powder of SiC was pressed in cylindrical form by the process called “wet way”. For the inicial pressing process was used a uniaxial squeezer and after that was used a isostatic squeezer, after that the samples were synthesized. The next step was the machining and polishing to improve the features of the surface of the sample. Then the roughness was measured, as also the Arquimedes method and optical microscopy and scanning eletron microscopy. Some innovations were done, in one of the lots little vacancys were done with organic material or silicon to reduce the weight of the sample; and the other innovation were the use of a slip film of SiC on the surface of the sample, that were after synthesized with LASER to reduce the roughness, in this samples the roughness were reduce in 50 % if compared with the other samples

Organização curricular e novas tecnologias de ensino do atletismo na escola

Introdução: Atualmente a Educação Física Escolar vem passando por grandes mudanças como, por exemplo, a implementação de uma proposta curricular para as escolas da rede estadual de ensino. No entanto, a falta conhecimentos sob os temas abordados, faz com que os professores trabalhem apenas conteúdos que apresentam um maior domínio o que torna, muitas vezes, as aulas de Educação Física em aulas exclusivamente de esportes coletivos (futsal, basquetebol, voleibol e handebol), deixando de lado outros componentes da cultura corporal. Diante disso, esse trabalho propõe apresentar algumas possibilidades para o atletismo na escola, de modo a buscar a responder as seguintes questões. O que os alunos devem saber sobre o atletismo na escola? Quais valores o atletismo pode acrescentar para estes alunos? O que os alunos devem saber fazer do atletismo? Objetivo: O objetivo do presente trabalho foi apresentar uma proposta curricular de atletismo para as aulas de Educação Física na escola do 6°, 7°, 8° e 9° ano do Ensino Fundamental (3º ciclo). Essas informações foram extraídas de entrevistas realizadas com professores especialistas em Atletismo e Educação Física escolar. Além disso, buscou-se construir um vídeo didático, para o 6°ano, sobre a apresentação das provas do atletismo. Metodologia: A metodologia de pesquisa utilizada para este estudo foi do tipo qualitativa e descritiva, pois consistiu na entrevista com docentes especialistas em Educação Física escolar e/ou Atletismo, e na elaboração de material didático e audiovisual. Conclusão: Todos os entrevistados bem como as propostas curriculares, enfatizaram a importância se reconhecer todas as provas do Atletismo

Possibilidades de organização de campeonatos de basquetebol e voleibol sub 1,80m masculino

Currently in the sports world, one of the prerequisites imposed by the organizers of sports sieves (selection of athletes) is the height, it becomes increasingly essential to play in clubs and teams worldwide. We noticed that teams base categories also suffer greatly from this height limitation. The objective of this research is to investigate the opinion of coaches, former coaches, players and former players and basketball players and volleyball on that possibility, or what to think about creating sub 1.80 m championships in men's tournaments. . This is a study of the qualitative and descriptive conducted with athletes and coaches volleyball and basketball courts, 6 volleyball players, six basketball players, volleyball players and a coach second technical basketball. We had the result of this work three main parameters: If athletes and coaches are in favor or not the creation of leagues, if there is any form of prejudice with the low in basketball and volleyball and opinions about the players lower in basketball and volleyball. Small players adhered to the idea of creating the league, high players were divided in high response and the coaches agreed saying that it grows with the Sports. Next step is the implementation, planning for these championships to assess the real possibilities of success of this initiative.

Análise de características físicas de agregados de resíduos de construção e demolição, para fins de pavimentação

This work presents the results obtained in analyzes of aggregates from construction and demolition waste produced by the plant of the City of Guaratinguetá. Using this data and comparing with the specifications of NBR 15115, it was found that the materials do not possess the requisite minimum characteristics to be utilized as a basis for low-pavement traffic. In order to identify the main reasons of the material does not fit in the standard, we used the data obtained in a study conducted by Professor. Dr. Luiz Eduardo de Oliveira at the plant of the company AB Environmental Solutions Ltd., located in Pindamonhangaba. With different characteristics, the aggregates from construction and demolition waste produced by this plant showed the possibility of using pavements. The use of these residues in paving reduces the impact on the environment caused by construction.

A organização e seus relacionamentos: uma abordagem semiótica do conceito de público

The organizations now have felt some needs in regards to changes in attitudes in what refers to the relationship with their interest publics. In this way, this work has as objective approach different themes, like concepts of organizational culture and the interrelations with the profession of Public Relations, besides the contact with notions in the area of People Management and human capital. As all organizations are constituted by interest publics, it will also demonstrate theories that refer to the different kinds of publics which the organization maintains relationship with, although, giving special attention to the internal public, considered one of the main types of public. For better comprehension of the performance of the internal public it was used the greimassian narrative semiotics that allow an exploration and analysis os diverse procedures made by such public. Therefore, it was possible to observe a great contribution from the theory in what refers to the assertion of the importance in maintaining good relationships with the employees of an organization, specially to affirm the identity of the employee making use of factors such as culture, values, principals, norms etc. Thus, it is believed that the strategic communication must be used with the intention of proportioning personal and professional well being to the employees, in a way that they may feel more and more integrated and committed with the organization, granting, like so, the organizational development and recognition

Estudo da tratabilidade de água pluvial utilizando coagulante natural a base de tanino visando fins não potáveis

This paper aimed to study the treatability of rainwater collected in Rio Claro, SP, using natural coagulant tannin based. The tannin was compared with other too primary coagulants, namely ferric chloride and corn starch. Assays were performed in laboratory scale using equipment known as Jarteste and aimed to study the conditions most suitable dosage and coagulation pH. First tests were conducted to compare the coagulating and determination of the conditions to be used in the following tests, taking as a criterion the greatest efficiency for water treatment. Also performed were performed tests to construct the tannin coagulation diagram, using the optimal concentration found in the previous phase, by varying the dosage of coagulant and the pH of clotting in order to determine the isoefficiency regions for apparent color and turbidity. Finally, tests were performed cyclically filtration with filter paper. Preliminary tests indicated that the vegetable tannin concentration 3% (m/m) from the commercial solution was presented the best set of results (84.3% removal of apparent color and 82.51% removal of turbidity) compared to ferric chloride (66.25% removal efficiency and apparent color of turbidity 67.82%) and starch (73.68% removal efficiency apparent color and turbidity to 67.19%). The coagulation diagrams indicate that the best region to work with vegetable tannin 3% is where the coagulant dosage ranges from 15 mg/L to about 37.5 mg/L and coagulation pH ranging from about 6.5 to 7.5. The cyclic filtration showed to be not efficient for the best dosage of coagulant, due to the process of clogging of the filter paper, but proved to be efficient for other dosages. Thus, for the waters studied, the results indicate that the natural coagulant based tannin is an alternative to conventional coagulants, possessing benefits of technical and environmental

Tratamento de água pluvial para fins não potáveis com utilização de amido de milho como coagulante em filtração cíclica em escala de laboratório

The aim of the present work is to investigate a simplified rainwater treatment strategy for nonpotable use. For this, there were simulated in laboratory scale the treatment conditions of a system that employs Corn Starch as a coagulant in cyclic filtration (from 1 to 5 filtration cycles). A commercial Corn Starch in different dosages was used (0,1; 0,2; 0,4; 0,6; 0,8; 1,0; 1,5; 2,0; 2,5; 3,0; 3,5; 4,0; 4,5; 5,0; 5,5; 6,0; 6,5; 7,0; 7,5; 8,0; 8,5 e 9,0 mg/L). The NBR 15527/07 recommended parameters were monitored on the inflow and outflow and compared to different first flushes (0.5; 1.0 and 1.5mm). The obtained results indicate that the 6.0mg/L dosage presented the best results (removal efficiency of 86% of turbidity; 88% of apparent color and absent of total and faecal coliform residuals). However, it was not possible to prove the filtration cycles benefit, in laboratory scale, because for some Corn Starch dosages the water did not present better quality when increasing the number of cycles.

Organização e implementação de um banco de dados para a sensibilidade ambiental ao óleo e avaliaçao de ações adequadas de resposta a derramamentos - São Sebastião (SP)

The need to know and to preserve the coastal ecosystems is justified by the whole importance that those ecosystems have for our society. Then, it is big the concern in guaranteeing that those places stay free from contaminations. Among the several types of potentials pollutants that can affect the coastal systems, the petroleum-derived are the ones that cause the worst impacts, given the frequency of these accidents. Rapid actions are necessary in order to minimize the oil negative effects . This answer is faster when the most sensitive areas are known and when it presents characteristics of larger importance, as for instance, the presence of sea harvesting or the habitat of an endemic specie. Besides, it is necessary to know which cleanup methods are recommended and which are not recommended for the reached areas, so, the corrected emergency plans for each coastal environment can be applied. It is in this context that this project was developed, implementing a geographical database for the different coastal environment of São Sebastião municipality, SP, and also the data about the best cleanup techniques for each segment of the coast. This database was made available by the internet, enabling the access for several types of users.

Acervo lúdico do CPA: organização, classificação e manutenção

We know that play is directly linked to the development and growth of the child. Thinking in this context, were created recreational spaces, more known as playrooms or toy libraries. This research seeks to understand the playful objects used in more visits with children, realized CPA, FC UNESP - Bauru. Therefore, it was necessary to identify the objects necessary to the demands of users of CPA, they were psychology trainees, fellows extension projects, graduate students, teachers and the subjects treated population served. Composed over 1000 objects, the collection must be appropriate to the needs of the CPA. The research in question is characterized as a case study, is related to our shares a scholarship project Playing in the Center for Applied Psychology - CPA, held in the collection playful and Toy CPA, FC UNESP - Bauru, used, in this case, as a field for this research.

As an instrument for data collection was mounted a notebook control in order to check the movement of the objects of the collection, also applied a questionnaire to teachers and trainees working in the CPA. At the end of the study we can say that the symbolic games and rules are the objects that are related to care provided in the CPA because of its capabilities to assist in various aspects of the development of children, with the most frequently used symbolic games with children aged 2 to 7 years and the games rules with children aged 7-12 years or more

Um estudo de caso sobre a organização escolar e as relações interpessoais dentro do âmbito educacional

Violence and school organization are always current issues. And to investigate these two issues, the present study was carried within a public school in the city for being considered a model of educative institution. The analysis focused on finding out why some institutions are considered good and others not and also to explain how these good relations within the school studied. Therefore, we first observed the school in its stages: entry and exit of students, breaks and classroom activities. Then consult the official documents, such as the Management Plan, Rules, Standards, among others. And finally we interviewed staff, targeting participants in the educational process (principal, teacher, staff, students). Facing this data we verified that a good relationship is needed on the beliefs and the search for a favorable environment is the aim for everyone, especially regarding to teaching-learning processes of a student, that is: teamwork. And as every institution has its flaws, we nee greater participation, especially of what we call school community (parents and relatives).

Resistências e transformações da organização agrária e histórico-cultural do bairro do Sobrado, Rio Claro/SP

O município de Rio Claro, localizado na região central do estado de São Paulo, durante o auge da era do café, da imigração tanto estrangeira como regional e da instalação de várias empresas, dentre elas a Companhia Paulista de Estradas de Ferro se urbanizou num acelerado ritmo, assim como tantas outras cidades do Brasil. Como resultado o aglomerado urbano cresceu, necessitando que seu perímetro expandisse para a zona rural, comprometendo tanto o seu patrimônio histórico quanto o cultural. Antigas propriedades datadas do final do século XIX que resistem à ação do tempo e mantém viva a riqueza e a cultura da época dão lugar à cidade. Esse processo é observado no bairro rural do Sobrado, localizado na região norte de Rio Claro, que vem sofrendo diretamente com a expansão urbana através da criação de novos loteamentos residenciais e comerciais. Portanto, o avanço da urbanização tem provocado à degradação e/ou desaparecimento dos fatos históricos e culturais ainda presentes nos bairros rurais do município
