CONSCIĂŠNCIA DE CLASSE E LUTA POR DIREITOS NAS REDES DE FAST FOOD
Esse artigo, fruto de um projeto de tese em desenvolvimento, tem como objetivo apresentar algumas questões que perpassam a discussão do trabalho em redes de fast food. A partir da compreensão de que os trabalhadores inseridos nesses espaços sofrem intensa exploração, são apontados elementos que contribuirão para o entendimento da forma como a ideologia opera em suas lutas por direitos. Apresentase, portanto, uma breve discussão sobre o trabalho nesses espaços, considerando o perfil etário predominante desses trabalhadores – jovens – e uma breve discussão acerca de ideologia e consciência de classe, que irá subsidiar as pesquisas a serem desenvolvidas
Práticas de otimização para mecanismos de busca na Agropedia brasilis.
A Agropedia brasilis é um ambiente virtual que, além de disponibilizar ferramentas para o trabalho colaborativo, oferece, aos grupos de pesquisa, desenvolvimento e inovação (PD&I) da Empresa Brasileira de Pesquisa Agropecuária (Embrapa) a possibilidade de divulgação, em páginas web, de suas atividades e resultados obtidos. Para que essas páginas obtenham maior visibilidade, é fundamental que estejam bem posicionadas nas listas de resultados obtidos pelos principais mecanismos de busca, como Google, Bing e Yahoo
Exercise as a Time-conditioning Effector in Chronic Disease: a Complementary Treatment Strategy
Exercise has been widely believed to be a preventive and therapeutic aid in the treatment of various pathophysiological conditions such as cardiovascular disease and cancer. A common problem associated with such pathologies is cachexia, characterized by progressive weight loss and depletion of lean and fat body mass, and is linked to poor prognosis. As this syndrome comprises changes in many physiological systems, it is tempting to assume that the modulation of the psychoneuroimmunoendocrine axis could attenuate or even prevent cachexia progression in cancer patients. Cancer cachexia is characterized by a disruption in the rhythmic secretion of melatonin, an important time-conditioning effector. This hormone, secreted by the pineal gland, transmits circadian and seasonal information to all organs and cells of the body, synchronizing the organism with the photoperiod. Considering that exercise modulates the immune response through at least two different mechanisms—metabolic and neuroendocrine—we propose that the adoption of a regular exercise program as a complementary strategy in the treatment of cancer patients, with the exercise bouts regularly performed at the same time of the day, will ameliorate cachexia symptoms and increase survival and quality of life
Study of Some Planetary Atmospheres Features by Probe Entry and Descent Simulations
Characterization of planetary atmospheres is analyzed by its effects in the entry and descent trajectories of probes. Emphasis is on the most important variables that characterize atmospheres e.g. density profile with altitude. Probe trajectories are numerically determined with ENTRAP, a developing multi-purpose computational tool for entry and descent trajectory simulations capable of taking into account many features and perturbations. Real data from Mars Pathfinder mission is used. The goal is to be able to determine more accurately the atmosphere structure by observing real trajectories and what changes are to expect in probe descent trajectories if atmospheres have different properties than the ones assumed initially
