1. Perspectiva dos Discentes de Medicina de uma Universidade Pública sobre Saúde e Qualidade de Vida
RESUMO Introdução Desde o preparo para o ingresso até a conclusão do curso de Medicina, há uma cobrança além do conteúdo; exige-se preparo emocional. Diante de um curso com carga horária integral, que demanda dedicação intensa para atingir boa bagagem teórico-prática e contemplar as exigências curriculares, e, muitas vezes, da distância da f

2. Developing a Mathematical Model for the Controlled Release Over Time of Sulfentrazone Herbicide from Biodegradable Polymer
In our research group, controlled release systems for the sulfentrazone herbicide has been accomplished by encapsulating this bioactive compound into calcium alginate (Ca-ALG) biodegradable polymer fashion and the release mechanisms were verified by using Korsmeyer-Peppas model (KP). However, the KP model does not allow to evaluate all the phenomena involved

3. Assessment of shop floor layouts in the context of process plans with alternatives
Abstract Paper aims The paper seeks to compare the performance of three layouts in a make to order (MTO) production system with high product variability. Originality No previous work sought to compare job shop, cellular and virtual cell layouts in an MTO system with high product variability, with just 21 resources, a low amount. The analysis considered m

4. GPS-Dependent Systems: Vulnerabilities to Electromagnetic Attacks
ABSTRACT The GPS is a satellite navigation system that provides location and time information. Such a system currently supports critical applications for military, civil and commercial users worldwide and is accessible to any operator by using a single GPS receiver. However, although being too dependent on GPS signals, just a few of these applications presen

5. Cardio-respiratory development in bird embryos: new insights from a venerable animal model
ABSTRACT The avian embryo is a time-honored animal model for understanding vertebrate development. A key area of extensive study using bird embryos centers on developmental phenotypic plasticity of the cardio-respiratory system and how its normal development can be affected by abiotic factors such as temperature and oxygen availability. Through the investiga

6. Fully Automatic Spot Welding System for Application in Automotive Industry
Abstract A Virtual Machine has led to a fully automatic spot welding system. All necessary parameters are created by measuring systems and algorithms running in the Virtual Machine. A hybrid operating circuit allows the Virtual Machine to read the exact process voltage between the tips of the electrodes every 50 µs. Actual welding voltage and current allow

7. Retroperitoneoscopic pyelolithotomy: A minimally invasive alternative for the management of large renal pelvic stone
Introduction: Large stones in renal pelvis can be treated with percutaneous nephrolithotomy (PCNL) or pyelolithotomy (either by open or laparoscopic techniques). PCNL is difficult in undilated system. For pyelolithotomy, laparoscopy is more preferable over the open surgery. Surgeons are more familiar with the tansperitoneoscopic anatomy than retroperitoneos

8. Variabilidade da frequência cardíaca após treinamento concorrente : comparação entre homens e mulheres de meia-idade = Heart rate variability after concurrent training : comparison between middle-aged men and women / Heart rate variability after concurrent training : comparison between middle-aged men and women
The autonomic nervous system dysfunction and the increase in chronic degenerative diseases are manifested by the aging process, leading to changes of the autonomic modulation cardiac, and therefore the heart rate variability. Regarding the response of the autonomic nervous system and cardiorespiratory adaptive responses are even less enlightening evidencing

9. Different approaches to the Composition of Neutron Stars and their Environment / Diferentes abordagens à composição e ao ambiente das estrelas de nêutrons
Even after 80 years of intense research, the composition of neutron stars remains unknown, since both the dense matter in the interior of these compact objects and the matter moving around them are in extreme physical conditions, unreproducible in terrestrial laboratories. In this Thesis, we follow four different interconnected ways to approach these extreme

10. O uso da educação online como alternativa para os programas de pós-graduação stricto sensu no Brasil. / The use of the education online as alternative for the after-graduation programs stricto sensu in Brazil.
So that a nation can be considered as developed, one of the major targets of its government should be the constant investments in education over the time. In Brazil, a country with continental dimensions, the offer of education for everybody is not an easy task at all. The successive governments in this country have put into practice several measures in all

The Repetitive Strain Injury / Work Related Musculoskeletal Disorders (LER / DORT) can arise in any field of activity; just there is a causal factor, ie, functions and jobs that expose workers to risk factors. These risk factors are present in the operator of the harvesting machinery activities. Throughout the workday upper limbs are highly required, necessi
