Verificação da dureza de gessos em função da compatibilidade com materiais de moldagem à base de borracha

Currently the most widespread material used in dies is gypsum that together with its simple technique has very satisfactory mechanical, chemical and physical properties. However, its compactibility with the impression materials can compromise the die surface quality. In our work, we studies the hardness of the two gypsum types: Type III (die stone) and type IV (improved die stone), as well as the influence of the contact with three types of impression materials: polymerized silicone for condensation (Xantopren), polysulfide (Permlastic) and polymerized silicone by addition (Provil). As comparison parameter gypsum was used in contact with a glass surface…(Complete abstract click electronic access below)

Verificação de terceira ordem de estruturas de concreto armado de edíficios

The change in design of a building can occur during its construction process, especially when this change involves greater amount of profit for the building company, as it is the case of adding extra floors. However, there must be an analysis of the structure of the building in order to see if it is possible to increase the number of floors without the need of reinforcement, as this need would result in higher costs for the building company. This graduation report presents this analysis by using the methods of third order verification of reinforced concrete structures

Qualidade higiênico-sanitária de sorvetes e sobremesas, na cidade de Botucatu, SP, Brasil, e verificação da produção de enterotoxinas por Staphylococcus aureus

Food poisoning can cause infection on its consumers by the presence of pathogenic bacteria, such as Salmonella and Staphylococcus aureus. Therefore, it is important to check its quality, which can be affected by many factors. The sanitary quality of foods can be assessed by thermotolerant coliform. Since food safety is a matter of great concern, this study aimed to evaluate the hygienic sanitary conditions of samples of ice cream and desserts marketed in the city of Botucatu, by determining the most probable number (MPN) of thermotolerant coliform, identification and enumeration of coagulase positive staphylococci and verification of classical enterotoxin production by strains of S. aureus and also for detecting the presence of Salmonella sp. Among the ice cream analyzed, 56.3% were unfit for consumption and between the creamy desserts, the percentage of unfit samples was 33.3%. Coagulase positive Staphylococcus and Salmonella were not found in the samples. It is then an inadequacy in handling and / or storage conditions in a considerable number of samples, indicating need for improvement in the conditions of preparation

Verificação do índice SINAPI para orçamento de obras

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

Verificação da eficiência da metodologia Seis Sigma na redução da divergência de estoque em uma indústria de condutores de fluídos

This work was developed in order to reduce the discrepancy found between the stock data of an item in the system and the amount found physically in stock in the company presented on this study case. Therefore, this paper makes a study on system of information that can assist in the collection, control and manipulation of data regarding the company's stock. It is very important to do the inventory management, so we can control the level of this sub-product to meet sales orders and production. In the study discussed below, we used the Six Sigma methodology to identify points that had flaws in the process and thus improve their work where the results show grater process control and provide a reliable database to the point where no further problems of lack of components in stock

Controle de qualidade em estruturas na construção civil

This work is to control the quality of the structures, procedures for addressing the assembly of the formwork, scaffolding and the frame of pillars, beams and slabs. He had also intended to show that the vibration of launch and concrete items are also important, if poorly implemented can undermine the structure. This work also shows that the mapping becomes essential if there is some problem in the concrete, where concrete was launched, could be identified. And finally check the product where the structure will be evaluated for how much their quality

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

Avaliação gastroprotetora da epicatequina e verificação de seus mecanismos de ação

The stomach is an exceptional organ, which functions are sterilize food ingested, form the primitive bolus, digest lipids and proteins, and to store food temporarily in the gastrointestinal tract. Its capacity of digesting food without digesting itself is amazing. This fact occurs due to innumerous protective substances adjacent to the gastric mucosa. When aggressive factors overwhelm the protective factors, a lesion in the gastric mucosa is formed. Lesions that reach the lamina propria are called gastric ulcers, which are classified macroscopically as openings on the gastric wall and; microscopically, as a gastric injury characterized with epithelial desquamation, mucosal hemorrhage, glandular damage and eosinophilic infiltration. The current therapy available is effective, although it causes collateral effects, therefore researching new drugs is necessary. This work aim to evaluate the gastroprotective effect of epicatechin against gastric lesions induced by absolute ethanol and non steroidal anti-inflammatory drugs which are the main causes of this disease currently, yet we aim to study the main mechanisms of action responsible for the gastroprotective effect. The results show that epicatechin has a significant macroscopic and microscopic gastroprotective effect against gastric injuries induced by ethanol and indomethacin, acting locally by augmenting gastric mucus secretion and it also acts via antioxidant system by holding total glutathione levels. Epicatechin’s gastroprotective mechanisms depend on the activation of sulfhydryl compounds and doesn’t depend on the NO-synthase enzyme

Verificação da eficiência do modelo de Mohler na resposta do comportamento de vigas mistas de madeira e concreto

The aim of this research study was to evaluate the structural behaviour of the wood and concrete composite system for bridge decks with emphasis on the metal shear connectors. Experimental tests were performed on composite specimens and wood and concrete beams with a metallic connector system in an X position, using CS100900-type screws. All specimens and beams were submitted to static loads until failure in order to obtain the strength and stiffness of the connection system. The experimental results for the stiffness of the beams were compared with the analytical results obtained through the Mohler model, presenting good equivalence for service loads. The experimental results obtained demonstrate that the most significant damage in composite systems occurred in the connectors' areas.
