Softwares livres e prototipagem rápida aplicados na engenharia

In modern industry we see a growing need for answers cheaper, accurate and quick to deliver solutions and products to be able to remain competitive. In this way the inclusion of open source software and Rapid Prototyping tools have proven very important to obtain the expected results. This work, through information gathering, analysis software and their applicability, search tools commercially available rapid prototyping will demonstrate the importance of these tools and will also present possible configurations for a space for rapid prototyping within the university, as a proposal to implement a rapid prototyping laboratory at the Faculdade de Engenharia de Guaratinguetá

O ato alimentar em três espécies de Artibeus de grande porte (Chiroptera: Phyllostomidae) do Sudeste brasileiro

The alimentary act of three species of frugivorous bats of the genus Artibeus: A. lituratus, A. fimbriatus and A. planirostris, in a total of nine individuals, was studied by observations in field and captivity, during the months of May to September of 2008. With the objective to caracterize the form of consumption of two tipes of fruits (soft and consistent) and it relates with the dentary structure of this bats, the alimentary act was film and analysed later. It had little variation between the species. The fruits had been consumed in similar way, being that statistics analisis had demonstrated that consistent fruits had received more lateral bytes than the soft fruits. The dentary analisis shown that the posterior teeth (pre-molar and molar) present important characteristcs to triturate pieces of more consistent fruits and the incisors serve to scrape the pulp of the soft fruits. This study it served to describe the form of feeding of frugivorous bats, that little is explained in the studies of alimentary behavior

Alimentar ou ser alimentado?: a expansão da agroindústria canavieira e a soberania alimentar em Flórida Paulista/SP

Devido às características de uso e ocupação do território nas últimas duas décadas, marcadas pela substituição da heterogeneidade da paisagem camponesa pela monotonia dos mares verdes do agronegócio, o município de Flórida Paulista contempla elementos representativos para analisarmos algumas das resultantes entre a expansão da cana-de-açúcar e a produção de alimentos voltados ao abastecimento dos locais próximos. Com isso buscamos entender, com base no recorte eleito para estudo, o percurso do alimento no espaço, desde as pequenas propriedades camponesas que ainda resistem à imposição do formato único, até os diversos pontos de venda/aquisição de alimentos disponíveis na área urbana, além do CEASA de Presidente Prudente/SP, responsável pela distribuição da maior parte dos produtos alimentícios encontrados nas bancas do município. A expansão das áreas monocultoras encontra-se sintonizada aos imperativos da lógica do abastecimento alimentar referenciado no movimento do alimento no espaço, no qual áreas antes policultoras, produtoras de alimentos, são sobrepostas pela geometria monocultural dos canaviais, o que diminui as possibilidades de abastecimento local e reforça o discurso de que os alimentos devam ser garantidos a partir de sujeitos estranhos ao lugar. Alimentar ou ser alimentado, soberania ou segurança, poder de decisão que emana autonomia ou dependência, constituem o eixo central no debate aqui proposto, de modo a identificar, a partir do movimento que denuncia a lógica por detrás do alimento, atores e setores entre a terra e o alimento. Com o objetivo de compreender as implicações do modus operandi próprio ao agronegócio... (Resumo completo, clicar acesso eletrônico abaixo)

Aproveitamento de sementes de abóboras (Cucurbita sp) como fonte alimentar

Brazil processes much of its fruit by producing natural juices, candy preserves, extracts and pulps; however, almost 60% of their total weight derives from peels, leaves and seeds. As a result, the emphasis lies most strongly on the use of waste, especially waste that is not commonly used by the food industry or by consumers. The use of seeds would increase the viable sources of raw materials, lower operating costs of industries and would promote the development of new food products, since they are our main sources of protein, fat, fiber, functional compounds, vitamins and minerals salts. This paper presents alternatives for the use of pumpkin seeds (Cucurbita sp), which are often underutilized or discarded. It also demonstrates the bioactive and anti-nutritional compounds and their health effects.

Avaliação dos aspectos da dieta alimentar de Pimelodus maculatus em dois importantes tributários do reservatório de Jurumirim, Alto Rio Paranapanema-SP

The species Pimelodus maculatus is one of the most abundant fish in many artificial reservoirs. Shows feeding plasticity and exploits all trophic levels in aquatic ecosystems. This study aimed to analyze and compare aspects of the diet of P. maculatus in two important tributaries (Taquari and Veados rivers) in the upper Paranapanema River system, and also investigate possible differences in the condition factor using its feeding habit as reference. Samplings were carried out every three months during 2011 and 2012 in two tributaries of Jurumirim's dam. After biometric analysis, fish were dissected to remove the stomachs that were fixed in formaldehyde 10% and conserved in alcohol 70%. The stomach content was analyzed under stereomicroscope and the food items were identified until the least possible taxonomic level. The diet was characterized based on the Alimentary Index (IAi). Feeding strategy and aspects of species autoecology were evaluated by the relation between abundance of prey-specific (Pi) and occurrence frequency (Fo) of the prey, and also was calculated the niche width of Levin (B). The condition factor was also established and values obtained in samples of both rivers were compared, correlating them with diet of the species

Chaveamento de cargas intermitentes usando sensor de corrente

Due to concerns about rational use of energy, several alternative technologies of power generation appeared, including the conversion of solar energy into electrical energy by photovoltaic panels. In low-income households, the refrigerator represents considerable impact on the electric bill, since it requires constant power given its use in food preservation. It is possible to reduce this share, with the use of an alternative energy source. This work presents a timed switching electronic system, which allows commercial equipment that is not affected by short interruptions in the power supply to use a photovoltaic panel as a source of alternative energy, which usually do not provide energy continuously. Switching is made automatically in case of low incidence of sunlight, and without any form of energy storage. Between each switching, there is a dead time without power supply, therefore preventing the use of synchronizers circuits between the photovoltaic panel and the public power grid. A circuit containing a 80C31 microcontroller is used to control the system’s switching. The photovoltaic panel’s voltage inverter is in H bridge configuration, and is also controlled by the microcontroller through Pulse Width Modulation, which makes use of preprogrammed tables to generate the control signals of the power transistors. Through the use of software simulations, the proposed system was tested, which is capable of supplying intermittent single-phase loads. The simulations indicates that the project developed in this paper can be assembled into a prototype and be tested under real operating conditions, as long as the scaling of components, the characteristics of the photovoltaic panel to be used, and the project involved load are taken into account
