Análise teórica e simulação computacional de um sistema de resfriamento líquido de processadores de computadores pessoais

This paper aims to study the thermal aspects involved in a liquid cooling system for processors, analyzing their competitiveness and efficiency across the fins and fan system usually used by personal computers, because electronic components become more potent and consequently current methods of cooling are becoming ineffective. The liquid cooling system and air cooling system have different heat transfer mechanisms that involve mainly convection and conduction heat transfer modes, and, furthermore, requires an analysis of fluid dynamics, which can evaluate the losses involved in the closed system, consisting in an exchanger heat pipe and water blocks in liquid cooling system or heat sink and turbo-axial fan in the air cooling system

Cálculo do tempo de permanência de um cilindro de laminação em um equipamento de aquecimento por indução durante um processo de têmpera

Induction heating is a process closely linked to the concepts of heat transfer. It also covers electromagnetic induction and effect of film. Many companies use this technology in their processes due to the high accuracy that can be obtained at temperatures induced. However the dominance of this technology is not common among Brazilian industries. This involves complex systems of equation and heat exchange in transient conduction, and convection and radiation losses. With this work we seek the ability to analyze which parameters influence over this process and the order of magnitude of time required for heating a cylindrical part

Produção e utilização de material didático sobre fisiologia da audição e neurofisiologia

The teaching of hearing physiology requires an knowledge integration of Human Anatomy, Biophysics, more precisely Bioacoustics and Bioelectrogenesis, as well as Neurophysiology. Students present difficulty to build knowledge about functional mechanisms of sound conduction and sensory transduction, especially if the elements are not visible forms, as the middle and inner ear structures. To make the teaching about hearing physiology and sensory perception easier, was produced a set of didactical materials about the subject. At first, a resin model that faithfully describes the anatomical relationship of the ossicles with the tympanic membrane was developed. Subsequently, a second model that, besides illustrates the mechanism of acoustic impedance overcoming, also reveals how acoustic sensorial transduction occurs in inner ear, was designed and produced. In the third didactical model, are visualized, through students interaction, areas of the cerebral cortex that interpret the different sensory modalities. In addition, were created three educational videos about hearing problems and a site on Human Hearing Physiology, available on Institute of Biosciences website. The results of this course conclusion monograph are presented in the form of articles that were submitted to Journal Physics in the School and the Journal of the Nucleus of Teaching

Modelagem do resfriamento para a zona termicamente afetada pela soldagem de tubos de aço carbono

Because the high consumption of welded pipe for exploration and conduction oil and gas, optimization of manufacturing processes is necessary to obtain better productivity, efficiency and cost reduction. The objective of this study is to analyze the forms of heat transfer during the welding of pipes using longitudinal submerged arc process them to propose a model for the temperature distribution in the welded region. For this analysis are addressed as the heat transfer modes operate in the specified welding process and the necessary considerations for the mathematical model were obtained. The calculations were performed and the simulations needed to obtain the temperature distribution in the tube were carried out. Therefore, the practice was satisfactory and the results showed a range of temperatures along the pipe for a particular model and the future suggestions for improvement of this work

Matriz Bertholdo/Ricci/Barrotte (BRB): uma simplificação de técnica para obtenção de guia de estratificação com compósitos

Advanced Layering composite resins can be facilitated by a technique called "Lingual Matrix", where a guide is made of elastomer by molding a previously waxed tooth or sculped in an intraoral test drive restoration. This technique has many advantages to sophisticated layering, facilitation stratification, anatomic construcrion and the stages of finishing and polishing. However, in some clinical situations, the unfolding of the steps to obtains this matrix can be time consuming or even infeasible. To facilitate the achievement of this apparatus, a technique was idealized allowing significant reducrion in clinical time. This matrix, called the "BRB Matrix" is widly discussed in a didactic and clinical manner in this article, presenting its advantages in clinical cases where it is imperative to use a guide for conduction a controlled layering. The simplicity of this approach, as well as reduced clinical time and finacial costs turn it feasible in an everyday clinical practice.

A psicopatologização da infância no contemporâneo: um estudo sobre a expansão do diagnóstico de transtorno de déficit de atenção e hiperatividade

The expansion of psychiatric labeling does not reach only the adult population, but also the problematic related to childhood have been captured by the speeches and practices of the medical-psychiatric knowledge and turned into psychopathologies which tend to be treated with the main resource made available by psychiatrics in the present times: the psychotropic drugs. This work presents a critical thinking on the expansion of the diagnoses of “attention deficit disorder and hyperactivity” (ADHD) both in children and teenagers and on the conduction of drug therapies. It follows that the processes of childhood psycho-pathologization and the trivializing of psychotropic drug prescription are related to the overvaluation of the biological conception of psychic suffering and to the economic interests of the great pharmaceutical laboratories which by means of several strategies influence the medical practices, factors that lead to exposure of these patients to possible side effects and the risks of stigmatization that must be considered.

O grupo como produtor de singularidades: o processo subjetivo como forjador de singularidades frente às pessoas que vivem com as DSTs

The personal experience respective is a description of an psychosocial intervention effectuated in the year of 2007 in an institution not government, in the city of Taubaté, with a group of women infected with the virus HIV. We will present in the short form our work, which happened through a therapeutic group, that had as device, the production of new process of subjectivizing with these women in the conduction of them condition of life after the infection with the virus HIV. To determine our actions use the theoretical assumptions of genealogy, of psychology and the theory of institutional operating group with emphasis on aspects of group discussion. During approximately twelve meetings with the denser group work topics such as social violence (inequality of rights, prejudice and stigma), treatment of the condition of serum positive when marked by ambivalence to treatment and the use of defense mechanisms: denial, projection and omnipotence, the weak and intense physical and mental suffering resulting from this process.We end our exhibition while presenting the discursive constructions and, consequently, the multiforms singular potentialities of the group that appeared with our psychosocial interventions.

Errâncias e itinerâncias de uma pesquisa avaliativa em saúde: a construção de uma metodologia participativa

The study presents the construction process of research methodology "Training in SUS Humanization: effects evaluation of training processes from institutional supporters on health productionin Rio Grande do Sul, Santa Catarina and São Paulo territories." There was a search for developing an appropriate evaluative practice to the training processes, a methodology that instead of evaluating on something, assessed along with the supporters who attended the training-intervention, a participatory methodology.Therefore, the constitution of the Research Interest Group was an eminent tool. Trained supporters comprised the research team to expand participatory possibilities of a large and dispersed group, producing interferences in the investigative process conduction, described and analyzed in the study.At the same time, their experiences interfered in the understandings they had until then about the intervention-training experiences and effects on their daily lives, after almost four years.Thus, the methodological approach was intrinsically linked to the construction of a subjectivity differentiated plan and necessarily collective, which shifted the position of supporters involved from mere data suppliers to a lateralityposition in relation to other actors.The trial afforded by participatory strategies allowed researchers and supporters to interfere and compose the evaluation scenario with remarkable performances throughout the investigative process.The survey configuration was like a bet on a given methodological architecture that, in seeking to overcome evaluator-evaluated logic produced information for (retro) feedingthe intervention triggered by it. In the formative dimension, it also went through working processes analyzed by supporters rescuing the indissoluble characteristic that health activities mobilize among intervening, training and reviewing.
