Estudo de causas de falhas em selos mecânicos de bombas centrífugas para circulação de óleo térmico

This study is about a heating line that uses thermal oil. It is located in a facility that produces interlayers used in cars windshields. A plastic resin is melted and is sent to a matrix called DIE where the interlayers are produced. The DIE needs to receive heat from the circulation of thermal oil in four different regions of its interior, to ensure the correct thickness of the interlayer. The thermal energy is provided by electric heaters and the flow of thermal oil is impelled by four mechanically sealed centrifugal pumps (one per region). The key point of this study is the fact that these four pumps of the system have reported successive failures in the mechanical seals. Apparently, a poorly designed project has burdened the system intermittently. The pumps operation condition is located in a region of low efficiency, according to the characteristic curves. This fact is the source of the noticeable reduced time between failures. Changes in the configuration of the facility and in the number of pumps will be proposed, aiming to achieve higher operational efficiency. The proposals will be mathematically analyzed according to the Hydraulic Institute criteria. At the same time, we will also keep focus on an in-depth study of a heating system structure, starting with a detailed approach for each component and discussion about its real need and economic viability. At the end of this paper it is shown that the gain in efficiency achieved with the new proposed configuration reflects not only in the reduction of maintenance costs, but also a potential improvement in energy efficiency. It is shown that these two aspects are closely related and together form the basis for the design of a reliable and efficient pumping system

Acidentes na infância atendidos no pronto socorro de pediatria do Hospital das Clínicas de Botucatu que motivaram internação

Accidents represent a major public health problem as they are frequent, preventable, and account for high morbidity and mortality rates. Children are the most vulnerable to accidents due to their inherent characteristics, and as a result of their physical, sensorial, psychomotor and cognitive limitations, which will only develop with time. Watchfulness and careful attention are of paramount importance, especially as children develop locomotor skills that are accompanied by curiosity about their surroundings. Child accidents, particularly those that could have been avoided, are the accidents most commonly seen in emergency and urgency departments. Urgency and emergency departments are the greatest allies in the attention to pediatric accidents as they offer adequate, immediate and specific high complexity care to patients at risk, viewing their vital stabilization. Investigating the causes and consequences of this insult is essential to establish a diagnosis and to contribute for the adoption of measures of prevention, control, and assistance. To identify the epidemiologic characteristics of the accidents involving children that received care at the pediatric emergency department of Botucatu Medical School Hospital and required hospitalization. This quantitative, retrospective, descriptiveanalytic epidemiologic study included all children aged 0-14 years who had had an accident and were seen at the Pediatric Emergency Department of Botucatu Medical School Hospital of São Paulo State University/UNESP between January 1/2008 and December 31/2009. A total of 227 medical charts were reviewed and 178 (78.4%) patients were included in this study. Of these, 116 (65.1%) were males and 62 (34.8%) were females. Children aged 5 - 9 years (38.9%) were the most affected, followed by those aged 10 - 14 years (37.5%). Fractures occurred in 138 (77.5%) of the cases, followed by foreign bodies...

Análise de causas de trincas em carro de translação de empilhadeira/recuperadora

The present work aims to study the possible causes of cracks founded and recovered in translation cars of ore Forklift / ore Reclaimer. To identify the possible causes of cracks observed on the equipment it was used a static approach analysis, using a finite element method as an analysis tool, using a specific structural analysis program. After making the model, a strain gage measurement was necessary because there may be significant amounts of masses of non-structural components that were not modeled and were not available in the drawings, as well as fouling ore. With the calibrated model it was processed analyses with the load cases of dead load, product, wind and excavation. After the processing, it was observed that none of these load cases resulted in values that caused the crack, so another three hypotheses were tested: depression and misalignment, jacking and translation of only three cars. Of these three hypotheses it was observed that the jacking coud be the cause of the cracks, because the distribution of stress. Due to the miss of parameters, like the height utilized in this process, it was not possible to affirm the real stress level

As mudanças climáticas e suas consequências observadas na Região Metropolitana de São Paulo e a importância da APA Várzea do Rio Tietê na minimização de danos

O maior rio do Estado de São Paulo, o Rio Tietê, teve, na Região Metropolitana de São Paulo, suas áreas de várzeas tomadas pelo processo de urbanização e metropolização da população. Parte de suas terras inundáveis passou por processos de aterramento e impermeabilização para que a instalação de indústrias e infraestruturas fosse possível. A APA da Várzea do Rio Tietê foi criada para controlar o processo de ocupação do entorno do rio e na tentativa de amortecer as enchentes causadas por tempestades, cada vez mais constantes. Essas chuvas torrenciais são causadas pela influência das Ilhas de Calor da RMSP com o encontro de brisas marítimas, e causam inundações e destruições

A interdependência da prática docente e a construção da héxis corporal de professores de Educação Física e suas consequências na unidade escolar

This article aims to show the interdependence between teaching practice and the construction of body hexis of Physical Education teachers and its consequences at schools. It can be observed by the social workers that teach it in a elementary school in the city of Araraquara- -SP. It was established, as basic assumption of this issue, that the social construction of body hexis of Physical Education teachers is a process in constant evolution, because it is the result of the life story with interventions from the social context in which the learner lives. The hexis is the dimension that allows the internalization of the consequences of social practices, and also its body exteriorization, through the way of speaking, gesturing, looking, walking, head posture, faces, ways of sitting, to handle instruments, more and more associated with the voice sound of social workers. Children are particularly attentive, in all societies, to these gestures and postures in which they express themselves in their eyes, anything that features an adult. Finally, it understands the importance of the body hexis in the learning process specifically in school physical education. This practice will incite important behavioral changes in their residence within the school and possibly in a higher education.

Halitose: limitando a qualidade de vida

The aim of this literature review is to observe the causes, symptoms and consequences of halitosis and the influence of preventive measures. Halitosis has multifactorial causes, and may have local and systemic origins. It can limit the quality of life of individuals and often occurs due to lack of knowledge of prevention methods. Therefore, it is important that professionals are better prepared and people informed about the physiological and pathological halitosis to prevent its individual and social effects.

Principais causas de perdas gestacionais durante o período embrionário em éguas

A perda embrionária consiste em perda econômica significativa dentro do processo de criação de equinos e representa custos adicionais para os criadores decorrentes das repetidas coberturas de éguas durante a temporada reprodutiva, além da diminuição do número de potros nascidos. São consideradas perdas embrionárias aquelas que ocorrem até o 49º dia da gestação e são decorrente de diversos fatores maternos e/ou embrionários. Atualmente, com a utilização da ultrassonografia, pode-se observar a vesícula embrionária a partir do 11º dia pós-ovulação, sendo possível o diagnóstico precoce de tais perdas. Devido ao grande prejuízo econômico na reprodução equina decorrente de perdas gestacionais, o objetivo deste Trabalho de Conclusão de Curso foi realizar revisão de literatura sobre as principais causas da perda embrionária em éguas
