The activation of aluminum surface has the most various purposes as for example the search for the surface activation mechanism and the corrosion products by mercury ions. The objective of this work is to study the reactivity of the surface of aluminum metal when activated by mercury ions (Hg2+), with the consequent formation of an Al-Hg amalgam. Results demonstrate that the kinetics of the reaction, by measuring the mass change with time of the corrosion product formed between Al and Hg, and analysis by infrared spectroscopy (IR) that the product of the reaction between the amalgam, located on the surface, and the atmospheric oxygen is Al2O3 (aluminum hydroxide). The results also indicate that the kinetics of the reaction between the amalgam (Hg-Al) and atmospheric oxygen is of first order and reach a region where there is no more formation of product

In this work we study the construction of a test rig made to simulate the Mechanical efforts in wich a drillstring is submitted. The model is based on the rig built at IDS, Germany. There are some fault liabilities while doing the project of the axis. Therefore it's important to analyze and take knowledge of this efforts in order to predict failures like rupture or fatigue collapse. The main objective of this theis is to show the operating principle of the test rig and it's construction. The accomplished study allow us to predict the drillstring behavior and from the economic point of view that is very important because failures results in equipments maintenance that requires time and money causing prejudice to the company. Using SolidWorks, a simulation software, the thesis approaches all the mechanical parts required for it's construction as well as it's working principle. Acquisition sensors like strain gauges, accelerometer, and torque transductor were also used in this model. The objective of this thesis is to create a simulation model to be eventually at FEG(UNESP). During the development of the study, it was possible to learn more about the drilling process and the mechanical efforts in which the drill pipe is submitted. The accomplished contributed with knowledge for the student in the drilling process area. Also during the development of the study it was possible to have contact with different areas of engineering but the study is specifically directed to the construction of the test rig. Therefore the main theme of this thesis is to show the operating principle of the test rig and it's construction

This paper presents a proposal to redesign a physical therapy device for patients with quadriplegia, called parapodium. With the help of the Association of Parents and Exceptional Friends of Guaratinguetá, it was possible to know the currently used device and from this it was conceived changes, allowing the increase of freedom of its central portion, in the down and across positions with mechanical drive . This adaptation is to introduce improvements in the routine of physical therapy professionals and reduce ergonomic problems resulting from repetitive strain during the transfer of patients to the parapodium. In addition to providing greater security for patients who require the use of this equipment. The proposed device comprises: wheel, gearbox and brake systems used for actuation, allowing a degree of turning of the rear post, along an axis which is fixed to the gearbox and the rear structure that permits posterior movement. The mechanism allows the rear post rotate from 0 ° to 90 °. The estimated cost to make the proposal is lower than the marketed parapodiuns, reaching the device's functional expectations

O artigo apresenta uma perspectiva sintética da concepção de criança, pontuando questões relacionadas à pós-modernidade e ao problema da violência sexual intrafamiliar, o que faz parte da revisão bibliográfica para a elaboração de dissertação do Mestrado em Psicologia Clínica e Social da UFPA. As reflexões são articuladas através dos pontos de vista da Psicologia e da terapia ocupacional, pois a primeira é a base do nosso mestrado, e a segunda, do campo de atuação. O pensamento pós-moderno valoriza o singular e o idiossincrático, assim, apreender o discurso sobre a criança nos remete à importância de compreender o que elas próprias pensam e sentem sobre a sua condição infantil. A Psicologia da qual nos valemos oferece, para as análises, o conceito de nutrição psicológica, que diz respeito ao provimento, pelos cuidadores, de alimentos positivos capazes de permitir à criança desenvolver-se de modo criativo e saudável; além desse conceito, a terapia ocupacional apresenta o de atividades expressivas.
