Avaliação de funcionamento das bombas hidráulicas do sistema de tratamento de efluentes da Empresa Parker Hannifin

On the field of the projects of hydraulic systems exists a lot of worries when we talk about the calculate of hydraulic pumps. In this case some facts must be considerate: length of tubes, fluid characteristics, height gauge, temperature, pressure, characteristics of tubes, flow required and others. For that mathematic calculates must be developed with the objective to optimize hydraulic pumps and agree to find an ideal machine (that don't requires more energy than necessary or less energy than it requires; that is the more critical case, cause exists the risk that the fluid pumped do not agree to become in your destiny). The wrong calculate of this machine can super-size its, bringing an excessive energy consumption. Actually it's an important subject because we are in the age of lack of energy what turn it more expensive. So the correct sizing of a hydraulic pump is connected with the fact that you have to uses the enough energy resources avoiding waste. The calculate of ideal pump in the pumping system is studied during years and a lot of specialists in this subject develop equations and theories to calculate its. Some researches study about this subject and all of them become to the same conclusion: to find the ideal pump we have to know the characteristics of fluid (cinematic viscosity), the required flow , overall yield (overall of motor x overall of pump) the high gauge or discharge pressure and the loss of repression. The pressure drop can be calculated with different theories: using Hazen-Williams, Darcy e Weisbach or Chézy (1775 - that starts the researches to calculate the pressure drop). Although the most used theory and what is most near to reality is the Darcy's equation. So, in this job the Darcy's equation were choice to calculate the drop pressure that consider what kind of flow we are studying: laminar or turbulent. The determination of the best pump to be used in the ... ( complete abstract click eletronic access below)

Impactos e características nos projetos hidrelétricos Sul-americanos: o caso de Inambari no Peru, o investimento brasileiro e a lei de consulta prévia, 2006-2011

Esta pesquisa trata de um grande projeto hidrelétrico, Inambari, que estava se transformando em realidade como parte de acordos entre o governo do Brasil no segúndo período de Lula (2006-2010) e do governo peruano de Alan Garcia – AG (2006-2011). Inambari é um dos mais recentes projetos hidrelétricos peruanos feitos para exportar ao Brasil. Mas, apesar de formar parte de um acordo entre esses países, por agora está detido devido a protestos e mobilizações da população dos territ´porios de Inambari contra a política hegemônica de AG. Analogamente ao caso da estrada Interoceãnica Sul, a construção e operação da Usina Inambari pode ser entendida como um caso emblemático no cenário Latino Americano atual. Esta não seria apenas o maior projeto hidrelétrico da amazônia peruana, custando aproximadamente 4 bilhões de dolares e prometendo um potencial de geração de energia elétrica de cerca de 2.200 MW para exportar ao Brasil por ano, mas também concretizaria o vínculo energético estratégico entre estes dois países através de um complexo de usinas e linhas de transmissão interconectados. Para sua concretização se conta com o amparo financeiro e legislativo dos dois governos e suas instituições de fomento, além de instituições de internacionais de investimento (como o BID e o BM) e do capital internacional (este útlimo proveniente principalmente de empreiteiras brasileiras beneficiárias do modelo de concessões federais). Aqui se estudam os potenciais impactos na economia amazônica do modelo vigente de exploração de recursos naturais hídricos amazônicos através do caso INAMBARI. A conclusão aponta que inexistência de participação popular como o maior entrave ao desenvolvimento amazônico e tenta explicar a novaconfiguração dos movimentos sociais que buscam voz para os povos da Amazônia bem como o pioneirismo peruano em relação a lei de consulta prévia

Avaliação da produtividade no trabalho organizado em turnos em uma empresa vidreira

Work organized in shifts, either for technological, social or economic imposition, allows the best use of means of production, increasing the overall productivity of the enterprises. At the same time, this type of work harms the individual productive capacity of workers, particularly those involved in the night shift. The objective of this work was to assess the behaviour of production in a continuous line and subjected to work organized in shifts. Through the statistical method of analysis of variance, Spearman's test and Tukey's method, was analysed the distribution of the productivity index measured in three fixed shifts of work in a glass company. The productivity index, provided by the integrated management system of the company, refers to the ratio of actual productivity to total productivity. The statistical analysis shows that factors of production, such as allocation of workers, do not interfere with productivity, showing an unexpected pattern, where the average productivity for the three shifts are close and the correlation between the number of workers on the line and productivity is low. The conditions of production had an adverse work environment with exposure to noise, heat, vaporized mist of lubricating oil and risk of accidents. The findings show that the calculation of productivity in use is limited and its use in company’s production control may produce distortions. It is proposed to examine alternative calculations methods that consider the overall productivity

Proposta de um processo de categorização de fornecedores para a execução de projetos

Nowadays, in business environment, organizations seek to differentiate through special programs and plans, taking the concepts of sustainability, performance and benefits generated for society. Based in this competitive environment, as companies depend on the use of subcontractors to perform services for your different customers, the work performed by them is directly related to the vision created by the final customer’s vision of the company responsible for the project. Considering that the supplier hired to execute the project does not share the strategic concepts related to the level of services to be offered to the final customers, thus creating the need to develop methods that enable the alignment between the project owner, responsible for preparing the executive project, and the supplier, responsible for the execution of the work. Tangent to this need, it was necessary to create a method of evaluation and categorization for suppliers to hired for the projects. As a result it has been proposed a process of categorization of suppliers, through the restriction of possible companies to be hired for a project designed to promote alignment between strategies and continuous improvement of the solutions offered to the market

Avaliação do efeito ambiental nas propriedades mecânicas e viscoelásticas de compósitos híbridos de titânio/fibra de carbono/resina epóxi

Hybrid composites combining metal plates and laminates with continuous fiber reinforced polymer, called fiber-metal (CHMF), have been particularly attractive for aerospace applications, due mainly to their high mechanical strength and stiffness associated with low density. These laminates (CHMF) consist of a sandwich structure consisting of layers of polymer composites and metal plates, stacked alternately. This setting allows you to combine the best mechanical performance of polymer composites reinforced with long fibers, to the high toughness of metals. Environmental effects should always be considered in the design of structural components, because these materials in applications are submitted to the effects of moisture in the atmosphere, the large cyclical variations of temperature around 82 ° C to -56 ° C, and high effort mechanical. The specimens of fibermetal composite were prepared at EMBRAER with titanium plates and laminates of carbon fiber/epoxy resin. This study aims to evaluate the effect of different environmental conditions (water immersion, hygrothermal chamber and thermal shock) of laminate hybrid titanium/carbon fiber/epoxy resin. The effects of conditioning were evaluated by interlaminar shear tests - ILSS, tensile, and vibration free

Avaliação da qualidade da atenção ao parto nos colegiados de gestão regional Cuesta Botucatu e Vale do Jurumirim

The humanization of childbirth implies the understanding of this event as an important experience, and requires the redefinition of human relationships from the review of the assistance project, the understanding of pregnant women condition and human rights. To evaluate child birth assistance using a score that was developed by Botucatu Cuesta Regional Management and Jurumirim Valley Collegiates. This is an epidemiological, descriptive study that is inserted in the field of evaluation of services, programs or health projects. The data has been obtained by direct observation of deliveries, emphasizing the humane care. Results: Approximately one third of the women gave birth in a tertiary hospital (34.1%) and it was their first babies (33%).24.8% of the women received prenatal care in high-risk services. 67.1% of the births were normal, and 84.7% had no companions in the delivery room. In 47.1% of the cases the delivery was performed by obstetrician who used anesthesia in 44.7% and episiotomy in 48.2% of the deliveries. More than half of the newborns were attended by the pediatrician in the delivery room and had a delivery graph completed. Although the present study shows that 67.1% of the births were normal, caesarean rate can be considered excessive, as the WHO points out that c-sections above 15% are unlikely to be justifiable. It is important to emphasize that the Ministry of Health has to have a commitment with all women to promote safe motherhood, even in cases when the pregnancy involves a risk for both the mother and the fetus. It is noteworthy that the created score allowed us to assess variables related to the humanization of childbirth and only average and quite similar situations among the three services were evidenced. We hope that with this study, managers and professionals that work in this area can be subsidized in order to offer effective humane assistance and quality service in the delivery
