Tesis electrónicas de la Universidad de Los Andes: adaptación y uso de la Plataforma Tede

Uno de los proyectos de gran envergadura de la Universidad de Los Andes (ULA) es la creación de la Biblioteca Digital de Tesis Electrónicas. Su consecución garantiza elevados niveles de interacción entre los actores internos y externos de la ULA a través de la consulta y publicación de la producción científica e intelectual de la Institución. En este artículo se presenta, en particular, la experiencia en la adaptación de la plataforma TEDE para la publicación de tesis electrónicas. La adaptación de la plataforma TEDE se llevó a cabo en tres etapas, a saber: a) Instalación, configuración y prueba de funcionalidad de la plataforma, b) Configuración y pruebas para el caso ULA, y c) Adaptación de la plataforma a la ULA. El resultado de esta adaptación fue una plataforma única que cumple con los requerimientos básicos establecidos para la publicación de tesis electrónicas en la ULA y que se ajusta perfectamente a cualquier institución académica de Venezuela. Muestra de esta experiencia ULA es su implantación en otras universidades nacionales como la Universidad del Zulia (LUZ), la Universidad Simón Bolívar (USB) y la Universidad Nacional Experimental de los Llanos Ezequiel Zamora (UNELLEZ).

Influência da geometria da plataforma na determinação de chumbo em zidovudina (AZT) por ET AAS

The aim of this work was to compare the performances of the L'vov and integrated platforms in order to overcome the interferences found on lead determination in zidovudine by ET AAS. Pyrolysis and atomization temperatures found with integrated platform were 700 and 1400°C, respectively. The characteristic masses were 12.7 ± 1.2 pg with integrated platform and 11.1 ± 1.3 pg with grooved platform. The ratio between the slopes of zidovudine and aqueous curves shows a decrease in the interferences when the L'vov platform is used (bAZT/b aq = 0.97 ± 0.10) and the detection limit found was 0.03 µg.g-1. That ratio was 0.85 ± 0.07 with the integrated platform.

Estudo das diferentes formas de fósforo nas águas da plataforma continental do Amazonas

Hydrological samples were collected on the continental shelf of the Amazon river to determine particulate organic and inorganic matter, dissolved organic phosphorus (DOP), phosphate, total particulate phosphorus (TPP), chlorophyll a, temperature, salinity, pH, water transparency, dissolved oxygen (DO) and saturation rate. The objective was to study the forms of DOP, phosphate and TPP. In the euphotic layer, the fluvial discharge from the Amazon river favored the distribution of phosphate, TPP and DOP. In the aphotic layer, the phosphate concentration increased due to the decomposition of DOP and TPP. This increase is due to the absence of photosynthetic processes.

Jogos de empresa: aplicação à gestão da qualidade no ensino superior de química

Business games have become a popular choice of pedagogical technique for teaching in higher education. The objective of a business game is to offer students the opportunity to learn by doing, engaging them in a simulated experience of the real-world. This paper discusses how a business game has been played by undergraduate chemistry students in a Quality Management course. The responses from the teaching evaluation questionnaires revealed that they not only improved their quality management practices, but also enjoyed working in teams. The level of participation by students was good and the classroom activities provided a meaningful learning experience.

Perfil dos bolsistas PQ da área de Química baseado na Plataforma Lattes

The Lattes Platform, an information system maintained by the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq), is the main source of information on Brazilian researchers. This paper presents a scientific output profile of the CNPq Productivity Research Fellows in the Chemistry area based on the information extracted automatically from Lattes curricula in the 2002-2011 period using the language "LattesMiner". This paper also provides a comparison with the results of Santos et al. (2010). The findings confirmed that the majority of the researchers are male (67.9%), classified as category 2 (63.2%) and working in the Southeast region (60.7%).

Resultados científicos do cruzeiro do "Baependi" e do "Vega" à Ilha da Trindade: contribuição para o conhecimento da plataforma insular da Ilha da Trindade

The oceanographic work realized during 10 days in the surroundings of the eruptive island of Trindade, 20º30'36" lat. S - 29º19'26" long. W, had as principal aim the determination of the insular plateau, whose knowledge was very insufficient. Thus were established some oceanographic stations and sounding lines were realized by means of an echobathymeter whose responses were initially verified with mechanical soundings obtaneid by means of a Thomson sounder. The insular plateau is very narrow and exhibits a sudden fall between the 100 and 120 m. depth line at 740 m. - 2950 m. from the coast. Its greatest depth is of 108,30 m. and its mean inclination is of 8,12%. The plateau of the island of Trindade is separated from that of the neighbouring group of Martim Yaz by great depths. The bottoms are rocky near the coast, the blocks having been produced by the rupture of the magmatic mass of the island. Further away from the coast, the size of the rocks gradually diminishes up to the fine sand thickness. In the litoral zone there are abundant tufts of living Lithothamnion with a rich associated flora and fauna, which partly covers the rocks themselves. Further off at sea, the spheres of the dead alga with its commensals are cimented together by sedimentation. The spheres are further broken up and become an integrating part of the sand. The results of the physical and chemical analyses of the sand bottoms are shown in tables 2 and 3. The coast is either of abrupt rocky walls falling down to sea level, or of shores, made of pebbles or of sand. Anyhow, there are frequently Lithothamnion terraces slightly inclinated towards the bottom (chemical analysis table 1).

Jogos para capacitação de profissionais de saúde na atenção à violência de gênero

A violência contra a mulher é reconhecida como um problema de saúde pública pela magnitude de consequências que provoca na vida e na saúde das mulheres. Entretanto, a atenção dada ao problema no setor é ineficaz em decorrência da invisibilidade da violência nos serviços de saúde. É preciso desvelar o problema nos serviços e capacitar os profissionais por meio de novas técnicas e novos saberes. Este estudo destaca o uso dos Serious Games (SG) para contribuir com a qualificação das práticas profissionais. Esses jogos são aplicações digitais amplamente utilizadas em diferentes áreas (saúde, militar, educação) e que apresentam conteúdos pedagógicos de forma lúdica e interativa. Um SG pode contribuir com a educação permanente de profissionais de saúde quanto à atenção à violência de gênero com base na abordagem de conceitos teóricos associados ao problema e sistematizados em um mapa conceitual. Observou-se que ações de capacitação quanto à violência de gênero, além de aspectos cognitivos da aprendizagem, abrangem aspectos afetivos, uma vez que envolvem mudança de concepções e práticas.
