The aim of this study is to perform a situational analysis of the Laboratory of pulp and paper-UNESP ITAPEVA for conducting proposal the accreditation according to ISO / IEC 17025:2005. The ISO / IEC 17025 establishes the criteria for those laboratories wishing to demonstrate their technical competence, which have an effective quality system and are able to generate technically valid results, establishing a single international standard for certifying the competence of laboratories to carry tests and / or calibrations, including sampling. The case study was conducted on laboratory Pulp and Paper Universidade Estadual Paulista (UNESP), campus Itapeva, where we compared the views of the technician responsible for the laboratory and a regular user. The generated conclusion is that the laboratory is unable to initiate an accreditation process, because it fails the requirements such as quality manual, register of subcontractors, research of customer satisfaction, schedule of internal audits, schedule for completion of critical analysis, profile of the functions required, functions current description, documentation of technical requirements for accommodation and environmental conditions, calibration programs, equipment calibration program, programs calibration standards and reports and / or certificate of test and / or calibration, that are in accordance with ISO / IEC 17025:2005, beyond that there is not the possibility to develop and implement a quality system without the commitment of everyone involved, regardless of the functional hierarchy

O cupim exótico Coptotermes gestroi, pertencente à família Rhinotermitidae, é um dos mais prejudiciais para os humanos, do ponto de vista econômico, causando grandes prejuízos no Brasil, principalmente nos estados de São Paulo e Rio de Janeiro. A manutenção de insetos no laboratório pressupõe o uso de uma dieta artificial nutritiva assim, este projeto, pretendeu selecionar a melhor dieta artificial entre 5 testadas, que fosse adequada para manter essa espécie de cupim. Portanto, foram realizados 5 diferentes bioensaios em arenas compostas por câmaras “ninho”, conectadas a câmaras “alimento” , que continham as diferentes dietas ou Pinus sp., madeira utilizada como controle. A sobrevivência dos cupins e o resultado final foi submetido a uma análise de variância que demonstrou que a dieta composta principalmente por - celulose foi a que apresentou os melhores resultados e foi considerada a dieta mais eficaz na manutenção dos cupins em laboratório.

O objetivo deste trabalho foi identificar o micro-organismo Y15C previamente isolado no laboratório de microbiologia industrial, da UNESP de Rio Claro, utilizando técnicas bioquímicas, além de otimizar a produção de ácido lático por meio de fermentação batelada simples e batelada alimentada. Considerando o potencial do micro-organismo para a produção de D(-) ácido lático, com 100% de pureza, isômero usado na síntese de polímeros empregados na produção de diversos materiais resistentes e biodegradáveis, foi feita a otimização do meio de cultura, tendo como fonte de carbono a manipueira. A manipueira por ser um resíduo do processamento da mandioca que contém grande quantidade de amido e quando hidrolisado pode ser uma fonte de carbono de baixo custo, quando utilizado pelo micro-organismo. O isolado Y15C foi identificado como Lactobacillus delbrueckii ssp delbrueckii, por meio de testes bioquímicos. Em relação à otimização dos parâmetros de fermentação, usando planejamento experimental, observou-se que a adição de componentes ao meio de cultivo, assim como a variação da temperatura não aumentou significamente a produção de ácido lático. Desta forma optou-se por trabalhar com as menores concentrações de AMM (1,6 mL/L) e citrato (0,96 g/L) e maior temperatura (43,4ºC). Para que haja aumento na produção de ácido lático podem ser realizados diversos tipos de fermentações, no caso deste trabalho foram comparados dois tipos de fermentação, batelada simples e batelada com alimentação constante. A maior concentração de ácido lático (41,6 g/L) foi observada que quando utilizada fermentação do tipo de fermentação em batelada... (Resumo completo, clicar acesso eletrônico abaixo)

The tanning wastes are characterized to be significant sources of pollution in the hydrosphere when non adjusted or disposed adequated form. That happens because this industry type uses the chromium to tan hides, and this element is present in discharges concentrations in final wastes, characterizing this waste type as dangerous, according to the Associação Brasileira de Normas Técnicas, através da Norma Brasileira 10.004 de 2004. Due to this, the research proposes a form to reduction chromium of the tanning wastes through the process of adsorption. For that were used mining-wastes of Corumbataí Formation clays, material commonly used in the production of ceramic products in Rio Claro (SP). They were accomplished laboratory essays that involved the preparation of different clays pulps and subsequent mixture of these with the tanning wastes, maintaining them under different mixing times and adsorption contacts. After the separation of the mixtures, the leached were chemically analyzed and it was seen the efficiency of chromium reduction and your relationship with the variation of different times of contact clays/wastes and different grain sizes used in the pulps preparation.

Brazil is nowadays the greatest bet of investors for the future due to its stable economy growth. The country has grown side by side with the greatest demand for electrical energy. The international appeal for renewable sources is causing a change in the Brazilian energetic matrix, raising the amount of energy generated by thermoelectric power plants. The construction of new power plants, running on biomass, requires a crescent number of capacitated personnel to run them. The Faculdade de Engenharia de Guaratinguetá – UNESP – has a steam laboratory; witch is deactivated, which has a thermoelectric plant of small capacity. The laboratory reactivation and the return of its activities can be an important tool in order to graduate engineer able to operate on such units. This paper proposes four new experiments to be simulated on the Collage’s Energy Dep. Steam Lab when it gets back to its educational activities

This work aims to make the closed loop control of a three phase induction motor, through the integration of the following equipment: a frequency inverter, the actuator system; a programmable logic controller (PLC), the controller; an encoder, the velocity sensor, used as a feedback monitoring the control variable and the three-phase induction motor, the plant to be controlled. The control is performed using a Proportional - Integrative - Derivative (PID) approach. The PLC has a help instruction, which performs the auto adjustment of the controller, that instruction is used and confronted with other adjustment methods. There are several types of methods adjustments to the PID controllers, where the empirical methods are addressed in this work. The system is deployed at the Interface and Electro Electronic Control laboratory in the Universidade Estadual Paulista Júlio Mesquita Filho, Guaratinguetá, São Paulo, then, in the future, this work becomes an experiment to be conducted in the classroom, allowing undergraduate students to develop a greater affinity to the programs used by the PLC as well as studies of undergraduate and graduate works with the help of assembly made

The State of São Paulo is responsible for the largest sugar cane production in Brazil, as well as the largest production of ethanol made of this raw material – which is widely used as fuel for automobiles. This utilization began in the 1970’s, with the institution by the Brazilian government of the National Alcohol Program (PRO-ÁLCOOL), as a consequence of the petroleum crisis, rising again five years ago, with the development of flex fuel cars. The obtaining process of ethanol originates residues; amongst them, vinasse is the one that’s generated in the largest amount (an average of 10 to 13 litres/litre of ethanol produced). The disposal of this residue in waters was only forbidden in 1978, but before that, researchers had already been investigating its utilization as raw material. This paper had the objective of accompany the biodegradation of vinasse by evaluating the oxygen comsumption during it until the ultimate Biochemical Oxygen Demand (uBOD), performed in twenty days; another objective was to analyse the biomass production of Saccharomyces cerevisae in this residue. Physical and chemical analyses of the residue were also performed, as well as acute toxicity essays using Daphnia similis and Dugesia tigrina, before and after its biodegradation. The physical and chemical analyses pointed elevated acidness (pH = 3,98), conductivity (8,30 mS/cm) and COD (25.693,43 mg O2/L) and mean quantity of suspended solids (5.246 mg/L). The toxicity essays indicated absence of toxic potential in vinasse after biodegradation for both species. The uBOD degradated until 88,22% of the COD, demonstrating the possibility of biodegradation of most of the residue’s organic load in a relatively short period of time. S. cerevisae caused a 37,03% COD diminution in vinasse, diminished its conductivity and promoted a slight elevation of the pH; it obtained low biomass...(Complete abstract click electronic access below)

A busca de compreensão da complexa dinâmica envolvendo os processos interativos entre professores e alunos tem motivado o desenvolvimento de pesquisas relacionadas a padrões de interação em sala de aula e suas consequências para o no contexto do ensino e da aprendizagem. Este trabalho sistematiza e analisa os conteúdos tratados, bem como as questões levantadas por uma monitora de um Projeto de Extensão em Anatomia Humana e alunos de ensino médio durante as atividades realizadas na bancada do sistema excretor-reprodutor em um laboratório de Anatomia Humana, além de identificar as classes de abordagens comunicativas presentes nessas interações. A ênfase em aspectos morfofisiológicos dos sistemas humanos, assim como a opção por um estilo de trabalho baseado na argumentação retórica, adotado pela monitora, renegou a um segundo plano tanto a interatividade quanto a dialogicidade como padrões de interação neste contexto estudado
