Estudo de casos de seleção dos materiais e processos para a fabricação de fuselagens

This work proposes a study on the materials selections and processes for the manufacture of aircraft and showing a methodology to reduce the manufacturing cost. The DFMA can be understood as a methodology that aims at reducing manufacturing and assembly costs and coupled with the increase of product quality through design simplifications. The most commonly material used in the manufacture of aircraft is aluminum alloys due to these possess great structural strength, good elasticity, and being stainless having a low specific weight (about 1/3 that of steel), reducing the weight of the aircraft. A case study in which an operation in the process of verifying the quality was generating unnecessary costs time / man for the company was also developed. The problem solution was simple, just removing the attachment process. It was found that the DFMA methodology is extremely important for the simplification of processes and projects, contributing to the reduction of manufacturing costs of aircraft

Mapeamento geológico-geontécnico de trecho da estrada vicinal na Serra de Itaqueri, Charqueada (SP)

Geological-geotechnical problems affecting escarps as well as embankment and fill slopes of roads and motorways may generate different types of unsteadiness, which are mainly arisen from the deficient knowledge about the physical environment. This results in unsuitable engineering projects and inadequate executions, which can be worsened by an occasional inappropriate maintenance of the construction. A geologically-geotechnically characterization of escarps and slopes is crucial in order to prevent these problems. This work deals with a geological-geotechnical study of 1:10.000 scale mapping in a stretch of a local road (CHQ-40) at the Serra de Itaqueri, Charqueada town, State of São Paulo. The stretch is known by several physical problems as erosion and mass movement. The methods of study were based on an integrative analysis of the diverse elements of the physical environment by using aerial photographs - to obtain the physiographic compartmentalization of terrain units - as well as field work - to accomplish the evaluation of the units by employing sketch lists. To achieve this, we selected several techniques in order to identify and classify different types of existing problems as erosion, landslide in embankments and fill slopes, rockfall, block rolling, among others. We also included the analysis of soil horizon, thickness and composition. The geological-geotechnical mapping resulted in six units: 1- Sandstones in cuesta’s backhill; 2 – Basalts in cuesta’s front; 3- Sandstones in cuesta’s front; 4 – Talus and colluvial deposits at cuesta’s foothill; 5- Sandstones of the Piramboia Formation in hillside; and 6 – Colluvial soil in the hill top. A characterization of the geological-geotechnical units is detailed, coupled to the cartographic material. Other cartographic products elaborated for this study included 1:10.000 maps of hypsometry, slope and curvature

Produção e caracterização físico-mecânica do compósito cimento-madeira com variação granulométrica dos resíduos lignocelulósicos

The need to reduce environmental damage and add value to waste causes more and more new alternatives appear to unite these two points. One of the main ways to achieve this in timber industries and the use of waste for making panels. This work was aimed at studying the influence of particle size and density in Eucalyptus mechanical compressive strength of cement composite wood. For this study was performed production and physico-mechanical characterization of specimens, using portland cement, water and waste eucalyptus. The methodology consists of a statistical study of the results obtained by calculating the density and axial compression tests and a subsequent comparison of these results with other studies. The results showed that there are significant differences in density and compressive strength when using different particle sizes the particles of eucalyptus. In general, the smaller the particle size, the lower the compression strength and the greater the density when the samples are produced with the same trait

A necessidade de se ter profissionais capacitados para pensar a questão urbana e propor soluções inovadoras é o ponto de partida para a criação do curso de Arquitetura e Urbanismo na Faculdade de Ciências e Tecnologia da Universidade Estadual Paulista “Júlio de Mesquita Filho”. Quando da sua criação, toda a estruturação foi baseada na infraestrutura já existente no campus para que posteriormente novas instalações, adequadas às especificidades do curso, fossem pleiteadas. Com apenas oito anos de funcionamento, alunos e professores enfrentam dificuldades no desenvolvimento das atividades em função da falta de infraestrutura adequada. Dessa forma, o presente trabalho é dedicado ao desenvolvimento de um projeto que atenda de forma satisfatória as demandas existentes no curso. A partir da elaboração de estudos de projetos análogos e de analises das necessidades do campus e suas necessidades obtém‐se as diretrizes que encaminham para a escolha da uma área apropriada para implantação nesta unidade universitária e pautam o desenvolvimento do projeto, que busca inserir‐se de forma adequada ao contexto préexistente

A prática pedagógica das lutas nas academias de ginástica

The fights are one of the most elementary manifestations of body culture, which are also constituted by sports, dances, games, and others. They are present in a lot of different ways, being very diverse among themselves. However, there is no consensus or agreements in the literature about the pedagogical practice of these modalities in fitness centers, sport clubs and sports centers. How do the teachers teach in these environments? What strategies do they use? How do they organize the contents? In what subjects they are based to execute the teaching and learning process? In this way, the objective of this study was to analyze some classes from different styles of fights/ martial arts teachers, trying to find what are their focus, goals, methodologies, classes’ dynamics and didactical and pedagogical procedures, aiming to check what is the focus of fights/ martial arts´ pedagogical practice in non-formal education. For this, it was selected one experienced teacher from the following modalities of fights from oriental origin: karate, judo, jiu jitsu and kung fu. The methodology used in this study consisted first in a literature review about the fights and sports pedagogy. Furthermore, there was one field research of qualitative nature, whose methods of data collection were divided in two: systematic observations of some classes of each teacher and semi-structured interviews with each teacher after the observation process, looking deeper into the pedagogical practice of these modalities. The results were analyzed through a content analyze, crossing the informations acquired with the instruments used. In addition to the description of these teachers and their classes, there was a classification of information, arriving the following categories: ritual and ceremony, tradition and discipline, didactical and pedagogical procedures ...(Complete abstract click electronic access below)

Confecção e caracterização de filmes finos de boro para a medida da taxa de reação 10B(N, a)7LI na terapia por captura de nêutrons pelo boro

The Boron Neutron Capture Therapy (BNCT), based on the 10B(n,α)7Li reaction, represents a promising modality for the treatment of cancers that are resistents to conventional treatments. So, it is necessary to find drugs (boron compounds) with high selectivity for each type of cancer, the neutrons source should be well characterized and the rate of 10B(n,α)7Li reaction should be measured with great accuracy as possible. This study aimed to develop a method for manufacturing thin films of boron, for measure the 10B(n,α)7Li reaction, and analyze the uniformity of the films. Five thin films of boron were manufactured with three different concentrations of boric acid, heated to transform the acid in boron, irradiated with thermic neutrons coupled to CR-39 detectors, in BNCT line at the reactor IEA-R1 IPEN/CNEN, São Paulo. After the irradiation, the detectors were chemically attacked with NaOH to reveal the tracks. The methodology presented is effective because it resulted in deposition of boron as thin film enabling the quantitative analysis of 10B(n,α)7Li reaction. The analysis of the uniformity of density of the induced tracks in CR-39 shows that, in most of the films, there is no uniformity in surface distribution of boron, but when the film is divided, we obtain some uniform sectors

Reflexão acerca das relações de gênero e inatividade feminina nas aulas de Educação Física escolar

As aulas de Educação Física escolar apontam para um cenário recorrente e ao mesmo tempo inaceitável: a inatividade feminina. Essa realidade surge como um marco negativo, uma vez que as conquistas femininas no “universo” do movimento estão consolidadas. Entretanto, essas conquistas podem não significar uma relação de equidade entre os sexos. Baseado nisso, pretendeuse investigar a prática pedagógica de dois professores de Educação Física no trato das questões de gênero e da inatividade feminina. A pesquisa realizada teve como abordagem a metodologia qualitativa de caráter descritivo. Foram observadas aulas de Educação Física de dois professores da rede pública de ensino da cidade de Rio Claro. Após o período de observação foi aplicada uma entrevista para as meninas, a fim de dialogar sobre a problemática da relação de gênero. Para essa coleta utilizou-se um gravador de voz para registrar a entrevista, que depois foi transcrita. Como resultado observou-se que as aulas acontecem predominantemente sem a interação entre os sexos, há um domínio simbólico masculino que faz com que meninos dominem o tempo e espaço da aula. Na entrevista as meninas mostraram-se contrárias a interação com os meninos, muitas vezes por motivos físicos, sendo assim, as práticas na Educação Física escolar estão permeadas de conteúdos que exigem rendimento. Conclui-se que há carência nas aulas de Educação Física de práticas coeducativas, o que ocasiona um aumento na distância entre os sexos, descaracterizando a condição igualitária que a escola deveria proporcionar e fazendo com que os corpos femininos neguem a interação com o sexo oposto, tanto por motivos biológicos, como por razões motoras.

Reanálise das defasagens de Prometeu e Pandora

In the present work it is proposed to do a revision on some studies on the dynamics of the Prometheus-Pandora system. In special, those studies that deal with anomalous behaviours observed on its components, identi ed as angular lags in these satellite`s orbits. Initially, it is presented a general description, contextualising the main characteristics of this system. The main publications related to this subject are analised and commented, in chronological order, showing the advances made in the knowledge of such dynamics. An analysis of the initial conditions, used by Goldreich e Rappaport (2003a ,b) e Cruz (2004), obtained through observations made by the Voyager 1 and 2 spacecrafts and by the Hubble space telescope, it is made in order to try to reproduce their results. However, no clear conclusion of the values used were found. The tests addopted in the analysis are from Cruz (2004), which reproduced the results and o ered a new explanation on the origin of the observed angular lags. The addopetd methodology involves the numerical integration of the equations of motion of the system, including the zonal harmonics J2, J4 and J6 of Saturn's gravitational potential. A fundamental consideration in this study is the use of geometric elements instead of osculating elements. It was found the set of initial data that best reproduces the results from Goldreich e Rappaport (2003a, b) and Cruz (2004)

Desenvolvimento de um plataforma analítica para análise qualitativa e quantitativa de peptídeos de cérebros de abelhas Apis mellifera

As abelhas da espécie Apis mellifera são conhecidas por sua organização social, comportamento devotado e aparente complexidade comportamental, sendo também consideradas excelentes sistemas-modelo para estudos de comunicação, aprendizado e formação de memória. Uma vez que o comportamento social dos insetos é resultante de interações complexas em diferentes níveis de organização biológica, torna-se importante estudar os peptídeos envolvidos nesse processo, já que estes são indispensáveis em muitos processos fisiológicos, funcionando como neurotransmissores, hormônios, toxinas, antibióticos, defensinas, neuromoduladores e neurohormônios. Desta forma, o objetivo do presente trabalho foi padronizar uma metodologia analítica visando à determinação do perfil peptídico do cérebro de abelhas da espécie Apis mellifera utilizando como ferramentas a espectrometria de massas e a cromatografia líquida. Foram coletadas operárias de Apis mellifera com 20 dias de idade, cujos cérebros foram dissecados e devidamente processados visando a posterior separação e identificação dos peptídeos. Foram testadas duas estratégias distintas para a separação e identificação dos peptídeos, denominadas on-line e off-line. Ambas baseavam-se na utilização de um sistema de cromatografia líquida sob fase reversa e um espectrômetro de massas do tipo electrospray/Ion Trap-Time of Flight, mas na primeira essas ferramentas estavam acopladas, enquanto na segunda os dois processos foram realizados separadamente. Tais procedimentos permitiram identificar 19 peptídeos pertencentes às principais famílias de neuropeptídeos de cérebros de abelhas já descritos na literatura, entre elas as Alatostatina, Apidaecina, Corazonina e Taquicininas. Os resultados obtidos indicam que a estratégia off-line foi melhor em comparação à estratégia on-line, devido à possibilidade de se trabalhar com cada fração obtida separadamente para as...

SIG e álgebra de mapas na elaboração de um mapa de potencial de erosão em áreas de silvicultura

Cette étude visait à générer une carte du potentiel d'érosion pour la Ferme Santa Edwirges, située à Lorena /SP. Les résultats ont etés classifiés en faible, modéré, élève et très élève potentiel d'érosion et la carte obtenue a été comparé par rapport aux autres cartes existantes pour la zone d'étude. La méthodologie proposée se basant sur une application qualitative simple L’équation Universelle de Perte de Sol (USLE ou EUPS), en considérant les parties de l'équation: érodibilité, la topographie et l'utilisation des terres. Les donnés ont etés intégrés par l'algèbre de carte dans l’environnement SIG de ArcGIS. Pour la représentation de chacune de ces parcelles, nous avons utilisé une carte des formations superficielles de la ferme, généré à partir d'une ré-interprétation de la carte géologique, une carte de la pente et une carte d'utilisation des terres, attribuant un poids d’important pour chaque catégorie de ces cartes dans le processus d'érosion et dans l'algèbre proposée. Les résultats obtenus sont compatibles avec les zones identifiées comme les plus critiques sur terrain. La ferme a été identifiée comme de potentiel d'érosion modérée et la partie sud de la ferme le plus critique, suivi du groupe conduit par la zone de cisaillement, par contre les plaines proches des rivières ont eté identifié comme la zone plus stable avec moins de potentiel d'érosionDe la comparaison des résultats de ce travail et d'autres qui ont fait antérieurement dans la zone d’intéresse, qui ont utilisé les paramètres géotechniques dans la représentation de l'érosivité des sols, nous avons pu voir des résultats similaires, en particulier dans les zones à potentiel élevé et faible pour l'érosion. De la discussion et analyse des résultats, la méthodologie proposée à eté validée

Um Estudo da modelagem matemática na educação matemática e seu potencial para o desenvolvimento do pensamento crítico

The implementation of mathematical modeling curricula represents a great challenge, both for teachers and students, since it escapes the traditional teaching methodology, i.e. when the teacher speaks to his/her students. This work presents, at least, one possible way of implementing mathematical modeling inside the classroom, and how this way encourage critical thinking in students. I see mathematical modeling as an opportunity to minimize student's rejection and increase their interest for mathematics, promoting their competencies to give points of scene in every day situations. The history of mathematics shows that mathematical modeling had developed since almost the beginning of human live, when men needed to solve problems that arose in the course of his life. Mathematics has become more and more abstract, but it is important to recall what was originated it. In this way, it is possible to make this subject matter more meaningful to students. I will make an introduction of mathematical modeling, presenting some important definitions. Based on this framework, I will present a classroom instruction understand on a 7 th grade classroom by myself. With this in instruction I sustain the idea that mathematical modeling has, in fact, a great potential to improve the quality of mathematics teaching. I also sustain that, the development of critical thinking, as a competence, way be achieved with it
