The purpose of this work was to define the processes through which the cooling of thermoplastics parts occur inside the mold cavity in an injection process. The plastic materials have become more widespread in the automobile industry and, among its manufacturing processes, injection moulding develops quickly, allowing the manufacturing of quality parts in great volumes. Data was collected from the injection of Volkswagen Gol NF 23X (Gol Generation 5). Using approximated methods for calculation for the heat Exchange inside the mould, in the cooling system, the required water flow was determined to properly cool the parts. Comparing the obtained value with Project specifications, it was verified that the method, in spite of incurring in some mistakes, is efficient in determining the flow of cooling fluid and serves as a verification tool for the parameters defined on project, and can be applied to simple projects. The definition of the cooling system, in practice, is dependent on innumerable variables and each case must be approached in itself, since the parameters for one product may not be ideal for another

The need to know and to preserve the coastal ecosystems is justified by the whole importance that those ecosystems have for our society. Then, it is big the concern in guaranteeing that those places stay free from contaminations. Among the several types of potentials pollutants that can affect the coastal systems, the petroleum-derived are the ones that cause the worst impacts, given the frequency of these accidents. Rapid actions are necessary in order to minimize the oil negative effects . This answer is faster when the most sensitive areas are known and when it presents characteristics of larger importance, as for instance, the presence of sea harvesting or the habitat of an endemic specie. Besides, it is necessary to know which cleanup methods are recommended and which are not recommended for the reached areas, so, the corrected emergency plans for each coastal environment can be applied. It is in this context that this project was developed, implementing a geographical database for the different coastal environment of São Sebastião municipality, SP, and also the data about the best cleanup techniques for each segment of the coast. This database was made available by the internet, enabling the access for several types of users.

The search for more reliable security systems and information management of these systems is leading to a growing progress in new technologies investments that allow the implementation of equipment with a high level of reliability, but also have an agile and practical operation. This led people to turn increasingly looking for home automation systems, enterprise and industry for the automation and integration of their systems. The identification by radio frequency is very widespread today for ensuring both agility in handling records data, the reliability of their identification systems, which are increasingly advanced and less susceptible to fraud. Attached to this technology, the use of the database is always very important for the storage of information collected, the area where the MySQL platform is widely used. Using the open source Arduino platform for programming and manipulation of RFID module and LabVIEW software for the union of all these technologies and to develop a user-friendly interface, you can create a highly reliable access control and agility places a high turnover of people. This project aims to prove the advantages of using all these technologies working together, thus improving a flawed system effectively safety, cheaper and quicker

Milk is considered a nutritionally complete food but it is also an excellent substrate for microbial growth. Therefore, it may pose a risk to consumers’ health. The aim of this study was to collect data on the occurrence of gastroenteritis outbreaks caused by the intake of milk and dairy products in the state of São Paulo, from 2000 to 2010. The data were collected from the records on foodborne illness outbreaks kept by the Division of Waterborne and Foodborne Diseases of the Center for Epidemiological Surveillance of the Department of Health of the State of São Paulo. A total of 239 outbreaks were notifi ed. They involved 2.418 cases related to the consumption of dairy products during the study period. The etiological agents were identifi ed in 79 outbreaks (33.0%). They were mostly bacteria (84.8%), especially Staphylococcus aureus. Most outbreaks occurred at home (59.4%) and during the months of January (14.2%) and July (12.5%). Most (24.1%) of the affected individuals aged 20 to 49 years. The results shows the need of better manufacturing and handling practices, as well as increasing the awareness of the population and relevant agencies about the importance of notifying cases and implementing preventive measures to ensure food safety.

The aim of this study was to evaluate the quality of weight measurements produced in Primary Health Care Centers in Botucatu and surroundings. 14 Health Care Centers were included, all of them located in four towns in the area of Botucatu (4,555; 5,656; 18,761 and 128,397 inhabitants). General conditions and scale calibration conditions found in those Health Care Centers were evaluated. In order to evaluate the weight accuracy obtained by the local team, 10 adult users of each Center were addressed by the rater during the service routine in order to get a new weight evaluation, immediately after the measurement made by the team. The statistic method applied for checking the weight measurement held in the Heath Care Center and the scales accuracy was the measurement error technique (MET). The results have showed that out of 19 scales, 6 of them overestimated the weight by 50 grams, 1 of them underestimated the weight by 200 grams and the others were accurate. Evaluated as a group, the result of the scale MET was 44.3g. Regarding the conformity of the measures obtained by the MET of the adults weighing in the Health Care Centers compared to the ones obtained by the researcher, the expected result was obtained in only one Center (< 100g). The results have showed data compromise, rather due to lack of health team training than due to the conditions of the equipment used for the measurement.

O objetivo do presente trabalho foi comparar duas sequências diferentes na rapidez e segurança no preparo de canais curvos simulados. Foram empregados 30 blocos de acrílico com canais simulados que foram divididos em Grupo 1 – La Axxess 20 e 35/.06 25/.06, 20/.06, 25/.04 e 20/.04 e Grupo 2 – K3 Universal (VTVT) – 25/.10, 25/.08, 35/.06, 30/.04, 25/.06 e 20/.04. No preparo de todos os blocos empregou-se a velocidade de 250 rpm e torque de 1.4N/cm. Foram confeccionados dois pontos externos de amálgama para mensuração do desvio e adotou-se 17 mm como comprimento de trabalho. No Grupo 1, dilatou-se até o instrumento 25/.04, enquanto que no Grupo 2 até o 25/.06, e cronometrou-se o tempo de preparo de cada bloco. Na análise do desvio, radiografias com lima k 15 (antes) e K 25 (depois) foram realizadas e digitalizadas, medindo-se o ângulo antes e depois no programa Digora for Windows 1.51. Os dados foram comparados pelo teste T-Student e Mann-Whitney. Os resultados mostraram que em ambas as técnicas não ocorreram diferenças significantes entre o ângulo antes e depois e que não ocorreu diferença significante entre os desvios médios do Grupo 1 (0,130) e do Grupo 2 (1,330). No tempo de preparo, o Grupo 1 foi significantemente mais rápido que o Grupo 2. No Grupo 1, ocorreu a fratura de 1 instrumento, enquanto que no Grupo 2 ocorrerem duas fraturas. Concluiu-se que ambas as técnicas são seguras para o preparo de canais simulados curvos, sendo que no Grupo 1 o tempo de preparo é menor.
