Efeito do treinamento com pesos na pressão arterial de repouso em idosas normotensas

INTRODUCTION: Resistance training (RT) has been widely used for older adults in order to minimize or reverse the deleterious effects of aging in the neuromuscular system. However, the potential benefits of RT on arterial blood pressure and heart rate at rest in older adults remain controversial. OBJECTIVE: To analyze the effect of eight weeks of RT on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) in older women without hypertension. METHODS: Seventeen women (aged 66.0 ± 5.8 years) without previous experience in RT were randomly assigned to either a training (TG, n = 10) or control (CG, n = 7) groups. Hemodynamic parameters at rest were evaluated by auscultatory method (mercury sphygmomanometer) and HR monitor (Polar), before and after eight weeks of experimental period. RESULTS: Reductions attributable to RT were found only to SBP (-13.4 mmHg, p <0.01). Although significant reductions were observed for DBP and MBP, the analysis of covariance showed no interaction Group x Time significant. CONCLUSION: RT proved an effective training to promote adaptations in the cardiovascular system of older women without hypertension. Eight weeks of RT can significantly reduce SBP at rest in older women.

Atmospheric Discharges are responsible for several lost in the electrical system therefore it´s done studies to find ways to reduce the problem caused by discharges. This branch of engineering is necessary the gathering, stock and analysis of large quantity of data to validate or refuse the many studies produced about it The CENDAT proposed a project to collect data on induced voltages in distribution lines and current waveform of the lightning, but a difficulty that arose was the accumulation of data due to lack of manpower available to catalog all the data collected. Thinking in this difficulty, the engineer Acacio Silva Neto CENDAT´s researcher with trainees began to develop a program to solve this problem. This work keeps the development of this program in order to solve the problem of accumulation of data

Estudo de melhorias dos painéis de baixa tensão da Faculdade de Engenharia de Guaratinguetá - UNESP

The protection and distribution systems for the electrics equipments are really important for the safety of products, process and final users, for an enterprise or even for a residence. For that, it’s necessary the utilization of low voltage switchboards for controlling the feeding of a charge, avoiding any kind of abnormality that can eventually occur. It’s necessary to pay attention in the cubicles conditions, and always verify if they are in accordance to the norms of the product, verifying also any kind of physical damage for the operator and/or users. In this line, the present graduation work analyses the low voltage switchboards in the college, checking if they are attending the actual standards, suggesting some improvements and later making a simulation of the creation of a new panel that reach all the needing in substitution of this actual, through the software Simaris. Using the research and lecture of norms and regulations for verifying the problems, this way we could register the greatest acting failures. These actions are made for becoming aware to the university about the danger in using electrics equipments without a minimum degree of protection, allowed by the law, and attempting to the urgency in changing this fails

Prefácios e notas do tradutor: tensão e acolhimento na relação com o outro

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.

Caracterização do fator de intensidade de tensão em corpos trincados através do método dos elementos finitos

The industry generally has sought materials with high mechanical resistance, low density, thermal stability and corrosion resistance. In the aerospace industry, for example, the use of aluminum alloys, such as Al 2024-T351 and Al 7075-T7351, have become essential. However, the use of these materials often do not resulted in a satisfactory performance of the component, since the presence of cracks can cause total rupture of the component, even with a tension below the yield stress of the material, unexpectedly. In this work, these aluminum alloys were analyzed and samples were modeled by the finite element method. Moreover, in the models were applied two different types of cracks, central and edge crack, a vertical force was applied to result in a tension 70% of the yield stress of the material analyzed. Through stress asymptotic distribution in the region near the crack tip were calculated the values of the stress intensity factors for each crack length, after the stress intensity factors characterized were compared graphically with the values of fracture toughness found in the available literature
