From the end of the 80s, the Brazilian higher education experience strong growth, coming from the private sector, which would intensify further in the late 90th Higher education has become a lucrative business. With a drop in the number of students entering and strong competition, the number of idle places in private institutions of higher education reached 49.5% in 2004. That same year, by Measure, was the University for All Program (PROUNI) program, to include high school students from public higher education, offering scholarships to those students in private HEIs. In exchange, the IES gain tax exemption. The objective of this research is to investigate the game of interest occurred in the formulation of this program and identify the model and the political game and has led to the creation of PROUNI, analyzing the process occurred since the wording of a bill, the issue of Measure Law and that the legitimacy PROUNI, with the most important changes made initial model. Since the first draft of the Law to the final Act, the PROUNI was disfigured in its main points, as the percentage of stock for paying students, the process of selection of stock and bond of the IES program. Throughout the process of creating the program, it is quite clear the performance of the institutions representing the private higher education. As reference for the analysis was based on Rational Choice Theory of Political Science. The basic argument of the methods based on rational choice is the maximization of the benefit will be the main motivation of individuals, but they can give that your goals can be achieved more effectively through institutional action and thereby discover that their conduct is shaped by institutions. Thus, individuals rationally choose to get to a certain extent constrained to join in certain institutions, whether voluntarily or not. The PROUNI was submitted by government and public policy covered by the mystical aura of the discourse of social justice and economic development, as in higher education includes a stratum of people who would not have access to the university, due to restrictions in the supply network public higher education. However, the greatest benefit from the program are the private HEIs, which through a difficult time in a scenario marked by high competition and idleness of nearly half of the vacancies offered. The PROUNI became a program that prioritizes access and not the residence of the student to higher education. More serious than a supporting program for students Fellows is a program supporting the institutions of private education

Leishmania infantum and Trypanosoma cruzi are trypanosomatids of medical importance and are, respectively, the etiologic agents of visceral leishmaniasis (VL) and Chagas disease (CD) in Brazil. People infected with L. infantum or T. cruzi may develop asymptomatically, enabling the transmission of pathogens through blood transfusion and / or organs. The assessment of the infection by T. cruzi is included among the tests performed for screening blood donors in Brazil, however, there is no availability of tests for Leishmania. Serological tests for T. cruzi are very sensitive, but not specific, and may have cross-reactions with other microorganisms. Thus, the aim of this study was to determine the prevalence of Leishmania infection in blood donors and assess whether the serological test for T. cruzi detect L. infantum. Among the 300 blood samples from donors, discarded in 2011, 61 were T. cruzi positive, 203 were from donors with other infections and 36 were from handbags with low blood volume, but without infection. We also assessed 144 samples from donors without infections and able to donate blood, totaling 444 subjects. DNA was extracted from blood samples of all to perform quantitative PCR (qPCR) to detect Leishmania DNA. The buffy coat obtained from all samples was grown in Schneider medium supplemented and NNN. All samples were evaluated for the presence of anti-Leishmania antibody. The serological results indicate a percentage of 22% of Leishmania infection in blood samples obtained from discarded bags. A total of 60% of samples positive in ELISA for T. cruzi were negative by IFI, used as confirmatory test, ie 60% false positive for Chagas. Among these samples false positive for Chagas, 72% were positive by ELISA for Leishmania characterizing the occurrence of cross reaction between serologic assays. Of the 300 cultures performed, 18 grew parasites that were typed by qPCR and specific isoenzymes, found the species Leishmania infantum crops. Among the 18 cultures, 4 were purged from scholarships for low volume and all negative serology blood bank, thus demonstrating that there is a real risk of Leishmania transmission via transfusion. It is concluded that in an area endemic for leishmaniasis in Brazil, serological diagnosis performed to detect infection by T. cruzi among blood donors can identify infection by L. infantum and although cause false positive for Chagas, this cross-reactivity reduces the risk of Leishmania infection via blood transfusion, since tests are not applied specific detection of the parasite. In this way, there remains the need to discuss the implementation of a specific serological screening test for Leishmania in endemic countries such as Brazil

Dado que las funciones específica del mercado bursátil no son de dominio público en nuestro país, incluso para aquellos que trabajan en el sector real, financiero y entidades guibernamentales, considero conveniente hacer una introducción al mundo de la bolsa, explicando en forma breve los orígenes de las bolsas, su razón de existir y su trayectoria en Colombia. Solamente mencionaré los problemas principales que enfrenta este mercado. Porque pienso que el mercado bursátil a pesar de las transformaciones tan aceleradas vividas en los últimos cinco años, sigue adoleciendo de fallas y limitaciones; todavía falta mucho por hacer.

Os ingredientes bioativos são geralmente suscetíveis à degradação durante o armazenamento ou processamento alimentar, pois muitos deles são instáveis física, química ou enzimaticamente, o que leva à sua degração ou transformação com a consequente perda de bioatividade. Para ultrapassar estas limitações a microencapsulação emerge como uma resposta viável para proteger e estabilizar os bioativos, oferecendo também a possibilidade de uma libertação controlada e localizada [1]. Os materiais de encapsulação, processo de produção, morfologia da microesfera e, por último, as condições de aplicabilidade são os fatores mais importantes a ter em conta no desenho de um novo produto microencapsulado, juntamente com a questão da estabilidade e propriedades funcionais. Por outro lado, para obter um produto bem sucedido deve-se garantir um alto rendimento de encapsulação, a reprodutibilidade do processo e o perfil de libertação e, ainda, tentar evitar a agregação das microcápsulas.

Contando con la nueva tecnología se ha incrementado la publicidad de las empresas del mercado laboral en el país. Dando oportunidades de empleo, colocando ofertas y requerimientos del recurso humano que necesitan a través de las denominadas Bolsas de Trabajo. Las universidades y los sectores productivos, gubernamentales y sociales del país; cuentan hoy en día con la posibilidad de acceder a una de ellas. Es por ello, que el aporte de este proyecto de trabajo de graduación esta encaminado a ofrecer a la Universidad de El Salvador la creación de una bolsa de trabajo electrónica que facilitará a aquellos estudiantes activos y profesionales su incorporación al mercado de trabajo profesional. Se desarrolla una bolsa de trabajo electrónica que pueda ser accesada por medio de internet, que sirva de enlace entre las empresas demandantes de recurso humano y los estudiantes y/o profesionales de la Universidad de El Salvador; logrando de esta manera la colocación de personal calificado en el mercado laboral
