Abstract: steel cylindrical silos, when empty, are susceptible to the crumpling of the sheeting of the cylinder by the wind action. this paper compares the effects of internal and external stiffening with columns on the aerodynamic behavior of cylindrical silos with conical roof. the theoretical studies leaded to wind tunnel experiments, which have been carried out on two types of scaled silo models, one with smooth surface (internal stiffening), the other with ribbed surface (external stiffening), both with two geometric height/diameter ratio of cylinder (0.5 and 1.0) and a conical roof pitch equal to 27o. based on the information gained during these experiments, external coefficients of pressure and drag and lift coefficients are derived for the cylinders, as well as the drag and lift coefficients for the conical roofs. with this, it is identified the best stiffening arrangement for an optimum design of cylindrical silos to resist wind loads. the final result is an updated data set, originated from tests with geometric and aerodynamic characteristics well conditioned, which are applicable to a variety of cylindrical silos.

Abstract: A extens o acadêmica pressup e uma a o junto à comunidade, disponibilizando ao público externo à institui o o conhecimento adquirido com o ensino e a pesquisa desenvolvidos pelas universidades. Essa a o produz um novo conhecimento a ser trabalhado e articulado. A Fisioterapia é, dentro da universidade, uma ciência aplicada tendo por objeto de estudo o movimento humano em todas as formas de express o e potencialidades, tanto nas altera es patológicas quanto nas repercuss es psíquicas e organicas. A fisioterapia na saúde primária tem por objetivo agir antes das manifesta es nocivas que causam danos à qualidade de vida do indivíduo, promover a saúde e prevenir doen as e incapacidades, diminuindo com isso, a mortalidade e o número de interna es. A preven o de doen as e os servi os de promo o da saúde destinados aos idosos devem ser desenvolvidos de forma que prolonguem a sua expectativa de vida, porém t o importante ou mais é a abordagem voltada para a melhoria e a manuten o da qualidade do tempo restante de vida. O objetivo desse trabalho é mostrar a importancia da extens o universitária, aliada ao ensino e a pesquisa, em idosos de uma comunidade através da fisioterapia preventiva. Participaram da pesquisa 15 idosos com idade variando de 60 a 90 anos, que residiam regularmente no bairro Luzia, na cidade de Aracaju, no mês de Agosto/2009. Somente foram incluídas no estudo as pessoas com mais de 60 anos de idade e que assinaram o Termo de Consentimento Livre e Esclarecido de acordo com o Conselho Nacional de Saúde lei 192/92. Foi aplicado o questionário funcional multidimensional do idoso adaptado que avalia: recursos sociais, recursos econ micos, saúde mental, saúde física e atividades de vida diária. Na avalia o dos recursos sociais obteve-se uma média de 2,67 + 0,62; nos recursos econ micos a média foi de 3,6 + 1,05, na saúde mental foi de 3,0 + 1,01, na saúde física 4,0 + 1,07 e nas atividades de vida diárias 3,67 + 1,40. Observou-se que a extens o mostrou ser de suma importancia devido ao fato de que une sociedade e universidade articulando ensino e pesquisa; a fisioterapia assume papel de importante relevancia no que diz respeito à preven o e ao tratamento motor do paciente idoso, através de suas técnicas e métodos específicos e o questionário funcional multidimensional do idoso adaptado mostrou-se um instrumento de importante relevancia, na medida em que avalia o idoso de forma global.
