Beside aging process comes the incidence of dementia and, among them Alzheimer's disease (AD) accounts for approximately 60% of cases. This disease is characterized as a neuropathology with unknown etiology that causes cognitive deficits and behavioral disorders. Caring for patients with AD can cause an overload, both physical and psychological, which can cause high levels of stress on the primary caregiver. It is necessary that the caregiver also receives attention and develop activities that promote health benefits, while providing moments of distraction from the task of caring. Nonpharmacological interventions may be favorable for improving health with consequent decreased on the levels of stress. The objective of this study was to conduct a systematic review of scientific papers that aimed to verify the effect of nonpharmacological interventions on stress levels in caregivers of patients with AD. To contamplate this goal was accomplished a systematic search in the following databases: Biological Abstracts, PsycINFO, PubMed/Medline, Web of Science, LILACS and SciELO. The following keywords and Boolean operators was used: “caregivers” OR “family” and “nonpharmacological interventions” OR “support groups” OR “therapies” AND “Alzheimer's disease” OR “Alzheimer's dementia” OR “Alzheimer” OR “elderly” AND “stress”. There were found 3studies that met inclusion criteria adopted for the present work, and none showed significant results for the variable stress. It is not possible to affirm, according to the studies, that nonpharmacologial interventions programs for caregivers of patients with AD are effective to influence and to control the stress. However, studies show benefits for other variables such as self-efficacy and confidence in relation to care... (Complete abstract click electronic access below)

This research aims to cover publications related to anxiety suffered by dancers and then to compare their psychological health promotion. This study was developed according to Capes, Scilelo and Google Scholar data basis, besides Sports and Dance Psychology books .These studies state that dance leads its practitioner to increase his self-perception, combined with body and mind work ,as long as the dancer’s limits and possibilities are respected. However, the fear of frustration, exhibition nervousness and expectations can trigger anxiety growth in moments of tension, such as performances. It shows that anxiety can interfere the dancer’s performance in a positive or negative way. It is also believed that, in a general way, his best performance can be achieved when he gets to a proper level of anxiety, which varies from person to person. A lot of authors mention different ways to promote a better balance of anxiety during dance sessions, developing students’ self-confidence, motivation, breathing and recuperation, besides using the benefits from dancing to improve practitioners’ body and mind health.This area lacks more specific studies to let new techniques be created and used by directors and dance companies, to enrich more and more the work of dancers’ emotional balance

Nowadays, the automotive industry is working to optimize the design of engines, in order to reduce the fuel consumption with acceptable efficiency ratio. This undergraduate thesis is aimed at perform a kinematic/dynamic analysis of a slider-crank mechanism that is part of a four stroke internal combustion engine, the same engine that was used in the analysis described by Montazersadhd and Fatemi (2007). Two algorithms were developed based on Kane’s method to calculate velocities and accelerations of the mechanism bodies, and provide the acting forces at connecting rod joints. A SimMechanics model was developed to simulate the engine, and monitoring the same parameters that were calculated with the algorithms. The results obtained with both approaches were satisfactory and showed good agreement with the values provided by Montazersadhd and Fatemi (2007). The obtained results showed that the axial component of the rod joint efforts was caused by the pressure exerted on the piston head,whereas the radial component was related with the action of inertia loads. Besides, this thesis presents a connecting rod assembly mesh that is going to be used for static and fatigue finite element analysis in the future

The Organizational Culture has been in the spotlight in the last 25 years, studies show the influence of the culture in the production processes and in the strategy decisions of the companies. Changes in the organizational culture is necessary in key-moments of the corporation and this transformation moment influences directly the personal life and the professional life of the employees. The objective of this monograph is to verify the application of the “Transformation Program”, which is the changing program of a technology enterprise, and to attest the acceptation degree and the knowledge of the employees about the program, as well the main difficulties found by the company while implementing the project. Using a quantitative pool, the acceptation degree, the knowledge of the employees and their engagement with the Transformation Program were analyzed by checking the favorability of the answers and comparing the percentage of the whole company and its locations, besides with the results an understanding change curve was created, it identifies the stage that he employees are during the changing process. An interview with the actual and the previous program officers and two project managers was done, in order to identify their alignment with the theory and their perception about the difficulties found while applying the program. It was noted that the employees have heard about the Transformation Program and the majority is in the exploration phase of the understanding change curve, although it is necessary an special attention with the leaders, because the researches showed that the leaders are acting like a bottleneck in the communications by keeping the information that should be shared

The purpose of this paper is to examine the paratexts, mainly prefaces and notes, written by translators on writings of foreigners' travels in Brazil, with the purpose of evidencing which perspective guided their translations, if the perspective of the foreign author is adopted or if it is that of the domestic reader. The works examined were published by the Brazilian publishing house Companhia Editora Nacional in the Brasiliana Colllection. Most of the translators adopted a welcoming discourse to the author in their prefaces, but their prefaces, translations and notes reveal a certain tension between what they stated and what was effectively done, with moments of rupture in which the author's meanings are questioned and even denied. According to my analysis, this happens because the several forces acting on the translation, the author, the translator and the text to be translated, the languages involved, the reader are not working linearly, but in constant tension. As a result, different perspectives are adopted in different translations, but in the same translation there are moments in which the foreign pole is privileged and moments in which the domestic pole emerges.

The increasing search for better performance at the automotive industry, especially on the matter of fuel consumption, caused a progressive evolution of industrial technology. For the wheel this study is based on the try of reducing mass and decreasing the moment of inertia, characteristics that directly reflect on the performance parameter, as consumption and acceleration, so that it also is effective on the growth of the profit margin, since it reduces the costs of the locomotion. In this paper will be applied the Finite Element Analysis to explain the wheel behavior and identify ways to improve the performance. To the analyze it will be simulated a test condition established by ABNT NBR 6751:2009 foreseeing a possible collapse through general yielding and fatigue. The load here presented results from the equation presented on the norms and in the datas provided by the manufacturer

A launching rocket and its payload are submitted to strong acoustic loads in some moments of its flight like lift off, during transonic flight and in the instant of maximum dynamic pressure. These loads could affect the payload and other rocket internal equipment. It must be taken into account that in the higher stages, where delicate control equipment and the payload are placed, the acoustic excitations are dominant. The knowledge of the acoustic loads is of great importance in order to provide estimated loads for the design phase, define intensity level to specify qualification and acceptation acoustic tests to which subsystems and elements of the launcher and its payload shall be submitted and to design an acoustic … (Complete abstract click electronic access below)
