This study has as main objective to identify the complains occurrences about pain in the spine segments, that are related to work standing posture, adopted by the collaborators in the production section of a food industry, in the city of Marília São Paulo state. A descriptive research and studying case was made, using 30 employees as a sample. It was used as methodological procedure, a questionnaire to obtain information on professional and personal data, posture to remain standing, the most uncomfortable postures in the work environment (signed by the form of Ranney, 2000) and pain (pointed out by Corllet and Manenica Diagram, 1980). It was also used the Nordic questionnaire (Kuorioka et al.,1986), validated in the Brazilian culture by Barros e Alexandre (2003) and adapted for the study, the direct evaluation and, a direct observation was made in the production work, a posture analysis using the OWAS Method. It was noticed that the posture of standing up is adopted during work, and 73.3% of the people that was interviewed said that they felt tired in consequence of this posture, especially when associated with trunk twists, trunk inclination and elevation of their arms above their heads. Most complains regarding pain through their bodies, by Corllet e Manenica (1980) pointed to the lumbar region, followed in the dorsal area and legs and in the neck area, shoulders and right thigh. The adapted Nordic questionnaire reveled the lumbar area, in 10 interviewed people (33.3%) as the area mostaffected by musculoskeletal symptoms, next in the dorsal area, with five people interviewed (16.7%) and one of them (3.3%) felt pain in the cervical area, none reported pain in the hips area. The postural analysis was applied using OWAS method, and it was identified the postures that demanded more effort in the four levels of musculoskeletal injuries. As conclusion, the standing up posture and the asymmetric and incorrect movements are related to pain in the spine, mostly in the lumbar area.

The high competitiveness and the search for newtechnologies that differentiate the product from the project,require the use of new digital tools. The computer aideddesign - Computed Aided Design (CAD), with electronicmodeling, simulation, structural analysis and production,performed in a virtual environment through the applicationof specific software, are available but their use is stilllimited. There are various software available in languagesand extensions to industrial production which, from 3Dmodeling, they can manage through Computer NumericalControl - Computed Numerical Control (CNC) machiningcenters, laminating, stamping, mold making and otherprocesses productive. This project aims to encouragecreativity and entrepreneurship in the community throughthe provision of technology computer aided design - CAD,with a view to implementation of machining technology.

The constant petrol fuel leak in gas stations has caused concern in many countries around the world. Those fuels have toxic organic compounds in their composition, like Polycyclic Aromatic Hydrocarbons (PAH), which are harmful to the human health. In this work the efficiency of the protection layer with a High Density Polyethylene (HDPE) membrane of 2.5 mm thickness was evaluated. The study was based in the diffusive process in the intact membrane by a permeameter developed to evaluate the diffusive process. The membrane was putted in the middle of the system to separate two sides: a local soil impregnated with diesel oil (in one side) and pure water (in the other side). The chromatography technique was conducted to evaluate the contamination in the pure water. The analyses were made monthly in a total period of 6 months of research. The results tests show that the membrane was less effective to antracene and naphthalene compounds. Despite that, the results showed that the HDPE membrane is a good alternative to prevent contamination of water and soil by the compounds under study up to one year, based on the performance in the time of study.

The paper explores some issues related to the production of knowledge in the academic fi eld, relating it to the problem of knowledge dissemination beyond this restricted universe. Taking on theoretical sources from Bourdieu’s fi eld concept and his studies concerning the university fi eld in the work Homo academicus, seeks to examine, in an exploratory approach, the operation modes from academic and diffusion fi elds, opposing the actions from so-called experts and intellectual media, or intermediaries.

As transformações que tornam a sociedade mais complexa, configuradas na Sociedade da Informação, possibilitam novas formas de acesso as informações e conhecimentos que se manifestam em diferentes rela- ções sociais. No Brasil a valorização da leitura é um tema bastante recente, já que o Plano Nacional do Livro e da Leitura – PNLL - é de 2006. Tem como prioridade transformar a qualidade da capacidade leitora do Brasil e trazer a leitura para o dia-a-dia do brasileiro. Um dos eixos do plano é a Valorização da leitura e da comunicação, com ações para criar consciência sobre o valor social do livro e da leitura. O plano aborda a comunicação relacionada principalmente a dois aspectos: acesso à informação e comunicação sobre a leitura. A comunicação está sempre no centro da existência para qualquer sociedade, em desenvolvimento ou não. A partir de pesquisas sobre a leitura, o Instituto Pró-livro, uma entidade de caráter privado sem fins lucrativos, cujo objetivo principal é o fomento à leitura e à difusão do livro, utiliza-se de diversas estratégias de comunicação pública. Dentre essas experiências destacamos a Campanha “Mãe, lê pra mim?”, como uma prática de comunicação que busca levar informações aos cidadãos a partir do entendimento de se ouvir “as vozes locais”.

The photopolimerization it is be widely used nowadays in different fields as materials, medicine and dentistry. To occur that synthesis is utilized dimethacrylates monomers and photoinitiators, the photoinitiator system more usual is camphorquinone/tertiary amine (ethyl-p-dimethylamino benzoate). However is knowledge that tertiary amines are toxics, so the aim of this work is replace toxic amine compounds to non-toxic compounds as glycerol and inositol. Therefore was used the FTIR technic to calculate the monomers conversion degree as well as Thermogravimetric Analysis-simultaneous differential thermal analysis (TG-DTA) and Differential Scanning Calorimetry (DSC) to evaluate thermal stability, combustion rate, degradation steps, oxidation and volatilization of all samples. The study shown no significant difference about thermal behavior of all polymers, the initiators system for efficient and more fastness was camphorquinone /tertiary amine system followed by ca mph o r quinone/glycerol system
