The increasing demand for alternative fuels lead to the search for solutions to use these fuels in old equipments and bring for new equipments the necessity of alternative fuels based burners. As a solution for these necessity the Gas Interchangeability`s studies came in evidence, because it studies the possibility of changing one fuel for another without changing the initial condition. In integrated industries, as most of steel industries, there is a link between process, the byproducts of one process are used as fuel for other process. There are new conditions for the equipments, that will be developed for these fuels, but even in these industries there will be situations which the byproduct won`t be available, and the process cannot stop. Using the gas interchangeability`s concepts is possible to work with security in both cases. Using alternative fuels in fossil fuel based burners and having a back-up solution for new technology burner. But using these new solutions were verified that there are some cases which the interchangeability`s methods does not work with satisfactory results, and for this reason, this study came to develop a new concept for the Method of Wobbe Index to evaluate the possibility to increase the range of the satisfactory results

The Engineering Education in Brazil is constantly changing since its inception always aiming to meet the market demand for this type of professional. To meet this market demand, the institutions of engineering education to bring within their organizations as the new curriculum guidelines Registration System. In 2008 the Faculdade of Guaratinguetá entered its new Registration System, from series to Credit. The failure rate for each system will be the basis for understanding what the best system for this institution

Photodynamic therapy, term introduced by von Tapeiner in 1900, can be defined as the administration of a non toxic drug, i.e., a dye, known as photosensitizer (FS), which subsequently will be illuminated with light of specific wavelength. PDT is based on the interaction among FS, oxygen and light, which through photochemical reactions cause cell death. The FS molecules must have a high probability to form the singlet state after the excitation, which can induce chemical changes in the neighborhood in two ways, called reactions type I and type II. The type II reaction is based on the exchange of energy to molecular oxygen, exciting it to its state of higher energy (singlet), which is highly reactive. The proposed mechanisms for cell death are linked to damage to the DNA, mitochondria and to the cytoplasmic membrane. Several pre‐clinical and clinical trials have been carried out and the PDT is already used in many countries for treatment mainly against certain types of cancer. The therapy also has been gaining strength in antimicrobial control, since the microorganisms have appeared increasingly resistant to current antibiotics. Another attempt to use the PDT is for the inactivation of macro‐organisms, such as micro‐crustaceans and mosquitoes. To this end I tested whether the photosensitizers methylene blue, rose Bengal and the chlorophyll a has insecticidal activity against the yellow fever and dengue vector mosquito, Aedes aegypti. Since these diseases have no effective treatments, its control is linked to the vector control, which has shown resistance to chemical pesticides used. Based on this, this work shows its importance, because it is a new type of mosquito control since all the photosensitizers used are low cost, do not generate toxic products at the concentrations used and showed good results in mortality. The best photosensitizer was rose Bengal... (Complete abstract click electronic access below)

This work refers a comparison between a government’s index budget and another one which take into account the traditional method, in other words, taking real values practice in market as base. For its achievement will be used the design of a low standard single-family residence, quantifying all the materials needed for its construction with Prices Compositions Table for Budget, provided from the PINI publishing. After that, was made two budgets: one based on the SINAPI index costs, provided from Caixa Econômica Federal and calculated for the Brazilian Institute of Geography and Estatistics; and another based on the costs used in the SESC work in Birigui city, as well as values collected from building material stores in the same city. Finally, with both finalized budgets, will be drawn a direct comparison in order to verifying if the index can be use as parameter for budget calculations for low standard residences

O depósito de amilina é um achado histopatológico freqüente em pacientes portadores de diabetes melito tipo 2 (DM 2) e parece estar relacionado à disfunção da célula beta pancreática característica desta doença. Apenas as moléculas de amilina que sofrem agregação in vivo, tal como a amilina humana, são citotóxicas para as células beta, enquanto as variedades não agregantes, como a amilina de rato, não apresentam efeito deletério. Com o objetivo de compreender melhor os mecanismos de toxicidade associados à forma agregante da amilina, um projeto em andamento em nosso laboratório estudou, por micro-arranjos de cDNA, o perfil de genes modulados pela amilina humana em ilhotas pancreáticas murídeas, comparando duas situações específicas: ilhotas tratadas com fibrilas de amilina (“amilina madura”) e ilhotas tratadas com oligômeros de tamanho intermediário (“amilina fresca”), já que evidências recentes apontam para um efeito deletério apenas de oligômeros de amilina. As ilhotas foram isoladas a partir de ratos Wistar, mantidas em cultura por 24 horas e a seguir tratadas com 10

The study aimed to assess the degree of dental crowding correction on the lower anterior region of patients treated with T4k functional appliance using Little’s irregularity index. Twenty caucasian patients of both gender (10 female and 10 male) were selected. They featured malocclusion Class I and II in mixed dentition, with chronological age between 5.7 and 11 years. The treatment lasted from 1 year and 11 months up to 3 years and 11 months. Lower anterior crowding was measured using Little’s irregularity index. Measurements were obtained on study models achieved before and after functional orthopedic therapy, using a digital caliper in millimeters and placed parallel to the occlusal plane. Overjet and overbite measurements were also performed using a caliper. Results demonstrated that the therapy provided significant decrease in overjet (average = 1.55 mm) and also in the irregularity index (average = 1.23 mm). There was a nonsignificant raise in overbite. There was no relation between the studied variables and the treatment period or even with the patient’s age in the beginning of the therapy. The treatment with T4k resulted on reduction and improvement of dental crowding.
