Discute-se neste artigo a concepção de partido defendida por Florestan Fernandes, principalmente na década de 1980. Na primeira parte expõe-se a teoria da revolução defendida pelo sociólogo e sua estratégia de socialismo. Numa segunda parte explora-se a tese de movimento socialista defendida por Florestan Fernandes no contexto de rearticulação da esquerda, no final da década de 1970. Na segunda parte são abordadas as teses defendidas pelo sociólogo acerca do Partido dos Trabalhadores (PT), principalmente as suas contribuições apresentadas no primeiro congresso do partido, em 1992.
Neste artigo discute-se as representações do rural no radioteatro de Florianópolis na década de 1950. O artigo é estruturado a partir da análise dos roteiros do programa Encantamento, melodrama do radialista Aldo Silva, do qual se depreende uma série de representações acerca das representações do urbano e do rural. Procura-se relacionar essas representações, encontradas em outras obras publicadas no período em Florianópolis, a um contexto mais amplo, a partir de uma bibliografia de teóricos da literatura, como Raymond Williams.
<p>Neste artigo discute-se os elementos comuns entre os discursos produzidos por alguns militares e o ideário do movimento Escola Sem Partido. Para tanto, são apresentadas algumas intepretações elaboradas por militares acerca da educação atualmente desenvolvida em escolas e universidades. Ademais, são analisados os projetos de lei em tramitação no Congresso Nacional que defendem a censura aos professores nas escolas.</p>
Drying food involves complex physical atmospheric mechanisms with non-linear relations from the air-food interactions and those relations are strongly dependent on the moisture contents and the type of food. Such dependence makes it complex to design suitable dryers dedicated to a single drying process. To streamline the design of a novel compact food-drying machine, a heat pump dryer component design optimization algorithm was developed as a subprogram of a Computer Aided Engineering tool. The algorithm requires inputting food and air properties, the volume of the drying container and the technical specifications of the heat-pump off-the shelf components. The heat required to dehumidify the food supplied by the heat exchange process from condenser to evaporator, and the compressor’s requirements (refrigerant mass flow rate and operating pressures) are then calculated. Compressors can then be selected based in the volume and type of food to be dried. The algorithm is shown via a flow chart to guide the user through 3 different stages: Changes in drying air properties, Heat flow within dryer and Product moisture content. Example results of how different compressors are selected for different type of produces and quantities (Agaricus Blazei mushroom with 3 different moisture contents or fish from Thunnini tribe) conclude this article.
