A acessibilidade e a inclusão em uma Instituição Federal de Ensino Superior a partir da lei n. 13.409

Abstract: RESUMO O presente estudo tem como objetivo analisar o processo de adequacao de uma Instituicao Federal de Ensino Superior a lei n. 13.409, de 28 de dezembro de 2016, que implementa cota para pessoas com deficiencia. A pesquisa e de natureza qualitativa e configura-se um estudo de caso unico. Foram entrevistados dois gestores da instituicao e levantados documentos relacionados ao tema para a composicao do corpus documental. Para o exame documental, utilizou-se o procedimento da analise de conteudo. Constatou-se que a instituicao examinada nao apresenta condicoes adequadas para o atendimento a cota para pessoas com deficiencia estabelecida na referida lei. Conclui-se que, mesmo a lei n. 13.409/2016 sendo justa e necessaria, as condicoes para a sua efetivacao por parte do governo federal nao foram criadas. O que deveria ser inclusao configura-se, na verdade, um processo de exclusao.

Hemolysis in extracorporeal circulation: relationship between time and procedures

Abstract: INTRODUCAO: A circulacao extracorporea (CEC) e indispensavel para a maioria das operacoes cardiacas, mas causa danos significantes ao sangue, dentre eles a hemolise. OBJETIVO: Quantificar as taxas de hemolise em diferentes tempos nas operacoes para revascularizacao do miocardio com uso de CEC. METODOS: Foram medidas as taxas de hemolise de 22 pacientes em 6 tempos distintos durante a revascularizacao do miocardio com uso de CEC: T0 - antes do inicio da CEC, T1 - 5 minutos apos o inicio da CEC, T2 - com 30 minutos de CEC, T3 - imediatamente antes do despincamento da aorta, T4 - imediatamente antes da passagem do volume residual para o paciente e T5 - 5 minutos apos o termino da passagem do volume residual para o paciente. Foram calculadas as taxas de hemolise entre os intervalos de tempo: T0-T1; T1-T2; T2-T3; T3-T4 e T4-T5. RESULTADOS: Os primeiros 5 minutos apos a CEC demonstraram maior taxa de hemolise (P = 0,0003) em comparacao as outras taxas calculadas, representando 29% da hemolise total ate T4 (imediatamente antes da passagem do volume residual para o paciente). CONCLUSAO: Nao foram observadas variacoes significantes nas taxas de hemolise durante a aspiracao na raiz da aorta (P > 0,38) nem com o procedimento utilizado para a passagem do volume residual de sangue no circuito para os pacientes.

Analysis of AeroMACS Data Link for Unmanned Aircraft Vehicles

Abstract: Aeronautical Mobile Airport Communications System (AeroMACS) is based on the IEEE 802.16e mobile wireless standard commonly known as WiMAX. It is expected to be a main part of next-generation aviation communication system to support fixed and mobile services for manned and unmanned applications. AeroMACS will be an essential technology helping pave the way toward full integration of Unmanned Aircraft Vehicle (UAV) into the national airspace. A number of practical tests and analyses have been done so far for AeroMACS. The main contribution of this paper is to consider the theoretical concepts behind its features and discuss their suitability for UAVs’ applications. Mathematical analyses of AeroMACS physical layer framework is provided to show the theoretical trade-offs. We mainly focus on the analysis of AeroMACS OFDMA structure, which affects the speed limits, coverage cell, channel estimation requirements and inter-carrier interference.

Avaliação de sistemas de gestão ambiental em granjas de suínos

Abstract: Due to the environmental impacts caused by intensive swine farming and the economic importance and growth of this activity, this study evaluated environmental management practices on swine farms located in the state of Sao Paulo/Brazil. In order to accomplish this, exploratory interviews were conducted with the managers or owners of 37 randomly selected farms. The resulting data was then used to create a questionnaire that contained eight questions, and to also create an electronic database containing questions and answers. Weights, varying from 1 to 10 based upon their importance in preventing or mitigating environmental degradation, were assigned for each process carried out on the farm. The farms were then classified as satisfactory, satisfactory with restrictions and unsatisfactory, if their scores were greater than or equal to 70 points, between 51 and 69 points or lower than 51 points, respectively. The results showed that approximately 62% of the swine farms investigated were considered unsatisfactory, since their average score was 43.61. Approximately 11% and 27% were deemed satisfactory with restrictions and satisfactory, respectively, since their scores were 59.50 and 84.40. For items considered important, such as the use of biodigesters and compost, 51.35% used no biodigesters and 67.55% and 62.15%, respectively, used no compost or their practices were unsatisfactory. The need for incentive programs to improve swine waste management on farms in Sao Paulo State was therefore made evident.
