Caracterização da demanda do pronto socorro do Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP

The demand for health services can be understood as an application needs the user has. The inability to use the outpatient services and limited supply of these make it possible for users to browse sites that focus attention on a greater possibility of entry doors, in which first-aid centers and hospital emergency match this profile, distorting the flow of patients in the network through an inverse demand of the movement hierarchy. Added to this, the burden of care in these services results in overcrowding and poor quality of care. Evaluate the demand of the visits occurred in the Emergency Room of the Hospital of the Medical School of Botucatu / UNESP (PS - HC - FMB / UNESP) during June-July 2010. A transversal, descriptive and retrospective. For data collection sheet was used in the proposed Service unit and the data it was filled out the form with the necessary items for the search. Made an exploratory analysis and frequency distributions for categorical variables of the form. Females predominated (56%) and aged 61 years or older with 30%. 96.5% were owned by DRS VI, and 62.5% of Botucatu. The attendance by the physician on duty and corresponded to 57.7% among the 23 medical specialties, Gastric (7.0%), Cardiology (4.5%), Medical (4.4%), urology (4.2%) and Pulmonology (4.1%) were the ones that stood out. The medical procedures performed that stood out were X-ray (46.4%) and electrocardiogram (ECG) (42.3%) and in most specialty care occurred, only the daily consultation with the patient. It was possible to characterize, so the demand for PS - HC - FMB / UNESP for the period June- July 2010, The predominance of the elderly shows that come along with aging diseases and addictions, causing a greater need for health services.

Preparação e caracterização de vidros contendo nanopartículas de Ag

This work consists of preparation and characterization of glasses containing transition noble metals and the study of optical properties of such materials. The glasses were prepared by quenching of the glass melt followed by heat treatment and polishing of the monoliths. The structural characterization of glasses was made using differential thermal analysis, X-ray, Raman and infrared spectroscopies, while the optical properties were studied by UV-Vis and M-Lines spectroscopies. Preliminary results have shown that the color of the glasses is dependent on both concentration of silver and the melting temperature of the melt. Controlled heat treatments have been used to induce the crystallization of Ag nanoparticles within the glass. The study of crystallization was accompanied by electron microscopy and UV-Vis spectroscopy. Data from electron diffraction, as well as chemical analysis, EDX, were obtained using a transmission electron microscope. EDX data have shown that the atomic percentage of Ag is higher on the nanoparticle. X-ray diffraction was used in order to characterize the composition of the crystals and cubic AgCl was identified as the main crystallized nanophase obtained after annealing

Utilização de água pluvial para fins não potáveis: análise do atendimento da demanda pelo método de eficiências para dimensionamento de reservatório para diferentes regimes pluviométricos brasileiros

Brazil has about 12 % of a life´s essential resource: the superficial fresh water of the planet. However, today it is possible to observe the bad management of this resource, generating serious consequences on the quality that results in the loss of the use´s availability. In this scenario, the catchment of rainwater for undrinkable use is an alternative that has been broadly studied for the scientific community. When planning a system of rainwater catchment, the sizing of the required volume of the tank that will keep the water has a fundamental importance for the project, seeing that the supersizing of the tank can bring high costs and the undersizing can bring shortage in the water supply. This paper used a methodology based on two concepts: the harvesting efficiencies and the attending efficiencies of the system. This method takes as principle that exist a perfect demand that minimize the repayment time, condition that happened when the efficiencies are equal. Brazilian’s cities with different weathers and different rainfalls where chosen to simulate the attending for different demands for a typical residence. The data where parameterized according to the roof area and the number of residents, that way is possible that a future conference can be easily done and it also ensure results closer to the reality. The results showed that cities with a lower period of drought, even those with high level of rainfall on the raining mouths, have lower potential of water supply. The cities where the rainfall is more constant and also more high, even small roofs areas and small tank´s volumes – about half of the size compare to the cities with less propitious conditions – can generate high levels of water saving. With an eye to promote the environmental sustainability, the investment on projects for the catchment of rainwater is a good alternative

Preparação de substratos de carbeto de silício para fins aeroespaciais

This conclusion thesis has the objective of produce substrates of Silicon Carbide from the powder of SiC for aerospace use. The powder of SiC was pressed in cylindrical form by the process called “wet way”. For the inicial pressing process was used a uniaxial squeezer and after that was used a isostatic squeezer, after that the samples were synthesized. The next step was the machining and polishing to improve the features of the surface of the sample. Then the roughness was measured, as also the Arquimedes method and optical microscopy and scanning eletron microscopy. Some innovations were done, in one of the lots little vacancys were done with organic material or silicon to reduce the weight of the sample; and the other innovation were the use of a slip film of SiC on the surface of the sample, that were after synthesized with LASER to reduce the roughness, in this samples the roughness were reduce in 50 % if compared with the other samples

Caracterização dos usuários do setor urbano privado sujeitos a cobrança pelo uso dos recursos hídricos do Estado de São Paulo nas bacias PCJ e avaliação da demanda de água deste setor como ferramenta de gestão

The present study is about data characterization and evaluation related to private urban users (legal entity) of the Watersheds of the rivers Piracicaba, Capivari, and Jundiai (PCJ), with the PCJ Collection System, sustained by the Department of Water and Power (DAEE), in order to: provide quantitative numbers about this sector, identifying the cities and economic activities corresponding to the largest water consumers, and determine the sector's share in the total charged contribution. The charge for water use is the most recent and the last instrument which has been implemented for the management of water resources, provided by the institution of the State and National Policy of Water Resources in 1991 and 1997, respectively, regarded as an important step towards the preservation and restoration of water resources. According to the data collected in the PCJ Collection System, the urban sector is the private sector that has the highest number of users in these watersheds (52,95% of users), but with less representation in the financial recovery (only 7%), due to its low water demand in their uses compared to the uses of other sectors. The collected data will also serve as both a parameter for comparing the amount of water used by different economic activities and municipalities in the PCJ watersheds and other locations, and as a tool for water resources management

Avaliação de juntas soldadas em tubos de aço carbono submetidos a altas temperatura e pressões

The welding process in industrial piping is still the most effective way to ensure the durability and quality of the wide range of industrial process, although because of the high demand for energy and quality of the produced products, the piping has been constantly tested for high pressure applications and still high temperature. The welding method analyzed is the TIG (Tungsten Inert Gas) welding or GTAW (Gas-Shielded Tungsten Arc Welding), which ones have as principal feature the utilization of a not consumable tungsten electrode in the torch extremity , in this process is necessary a protective atmosphere of inert gas. The welding TIG advantage is the obtaining of a welded seam clean and with quality for not has slag after the welding. This work has as objective show the variability in the carbon steel piping welding parameters and by the tests in four proof bodies will be shown the influence of the variation of the welding methods in a welded seam. The tests will vary since the piece to be welded preparation, till penetrating liquid tests, welding macrography, welding x-ray and traction tests. Even been a clean and with quality welding is necessary a final inspection in the seam welded looking for defects almost inevitable resulted of the welded process, the obtained results have the objective of indicate and minimize the defects to ensure quality and durability of the welded seam

Energias alternativas: potencialidades para as regiões de maior demanda energética no Brasil

Since the beginning of life in society, the human being has sought sources of energy that can be used continuously, or stored to be consumed in times of need. The various energy generation processes has enabled the human race for the implementation of many activities ranging from food preparation, handling of large industries and even the possibility of total annihilation by the availability of powerful nuclear weapons. In Brazil, whereupon the various deleterious aspects and especially the finite resources used on a large scale for the energy conservation, there is a huge devotion of society referred to the prospects for alternatives to the use of energy in local, regional and global, but overall, as it wouldn’t be different, the main factors in this scenario are economic. The fact that the unused potential of a region in the use of alternative sources of energy leads to a larger socio-environmental prejudice generalized to all. The purpose of this project is targeted for a comprehensive, systemic and integrated discussion about some of the main alternative energy sources, associated with technical procedures related to them, to contribute to a better and effective use of natural resources available in each region of the country, in order to minimize the impacts on the environment in which they are inserted.

Comprimidos de HPMC contendo nimesulida: preparação, caracterização e estudo dos mecanismos que regem a liberação do fármaco

The pharmaceutical innovations, such as the use of polymers to control drug release, create possibilities for a better action of the drug in the body, which causes a a more effective therapeutic effect and a safer treatment for the patient. In this work, were prepared and characterized matrix tablets of hydroxypropylmethylcellulose (HPMC) containing nimesulide as model drug to evaluate the performance as a controlled release system. HPMC, a cellulose ester, is a hydrophilic polymer that undergoes swelling, i.e., absorbs water and forms a gel layer controlling drug release. The characterization of powders was performed by analysis of particle size and morphology, density, compressibility index determination, flow properties and determination of swelling profile. The tablets were evaluated according to their physical parameters of quality and to the in vitro release of nimesulide, as well as the analysis of the mechanisms of drug release by appropriate mathematical models. The set of results showed that the HPMC/Nimesulide mixture exhibited satisfactory physical characteristics (size, shape, density and flow). The release profile demonstrated an effective control upon drug release in enteric environment and presented more correlation with Korsmeyer-Peppas’ and Weibull’s mathematical models, indicating that the release of nimesulide occurs through the relaxation of the polymer chains
