Fugas de calor y aprovechamiento de efluentes en la optimización de ciclos Brayton totalmente irreversibles
Herrera, C. A;Rosillo, M.E;Casta?o, L;
Revista mexicana de física , 2008,
Abstract: optimization of maximum power and minimum rate of entropy generation is performed on a complete and realistic brayton cycle-irreversible components, dissipative flows, power consumption on fluids movement, heat exchange through finite temperature gradients, heat leaks, and effluents unrecovered exergy-. the sets of values that produce optimum objective results are determined using fixed design parameters and variables under typical operational ranges. this work analyzes the heat leaks and effluents exergy recovery level on the optimizing set and on the system behavior. an illustrative example is presented as a study case, showing difficult-to-predict performances. this article illustrates a method which can be implemented in a computer and allows to asses existing systems and upgrade designs.
Fugas de calor y aprovechamiento de efluentes en la optimización de ciclos Brayton totalmente irreversibles

Revista mexicana de física , 2008,
Abstract: En este trabajo se realiza optimización de máxima potencia y mínima generación de entropía sobre un modelo totalmente realista de un ciclo Brayton (máquinas irreversibles, flujos disipativos, consumo de potencia en todo trasiego de fluidos, transmisiones de calor a gradientes de temperatura finitos, fugas de calor, desaprovechamiento de efluentes, restricciones en caídas de presión y tama o de intercambiadores). A manera de ejemplo se presenta un caso de estudio, en el cual, para unos parámetros de funcionamiento dados y variables dentro de rangos típicos, se determinan los conjuntos de valores optimizantes para las funciones objetivo, y se analiza la influencia de las fugas y del nivel de aprovechamiento de la exergía de los efluentes sobre estos conjuntos y sobre el comportamiento general del sistema. Los resultados obtenidos muestran comportamientos difícilmente predecibles. Este artículo ilustra un procedimiento implementable en computadora y que permite hacer evaluación de sistemas existentes y mejoramiento de dise os

Abstract: Objetivo: Hacer un estudio de la utilización de psicofármacos del grupo de antipsicóticos atípicos dentro del Centro Penitenciario de Málaga durante los a os 2003/2004 y compararlo con el Distrito de Atención Primaria de referencia (Distrito Guadalhorce). Material y Métodos: Se ha realizado un estudio retrospectivo sobre la utilización de antipsicóticos atípicos en el Centro penitenciario de Málaga durante los a os 2003/04 y se ha comparado con la utilización que de estos fármacos se hace en el Distrito de Atención Primaria (A.P.) de referencia. La información sobre consumo de medicación se obtuvo a partir de las ordenes médicas recibidas en el centro durante los a os de estudio. Para la clasificación de principios activos se usó la clasificación ATC (Anatomical Therapeutic and Chemical Classifying System) y para el cálculo de envases, la base de datos propia del centro (SANIT 3.0). Para el cálculo de DDD se utilizó la DDD/1000 habitantes día. Resultados: Se ha incrementado la utilización de antipsicóticos atípicos a nivel del C.P. Existe una tendencia hacia la mayor utilización de quetiapina a dosis bajas mientras que ha disminuido la utilización de risperidona en el a o 2004 respecto a 2003, aunque continúa siendo el de mayor utilización tanto en DDD como en envases consumidos. La situación en Atención Primaria es exactamente la contraria. Conclusión: El uso de este grupo de medicamentos en estudio ha disminuido a nivel de Atención Primaria (A.P.), posiblemente debido a medidas especiales de control médico (visado). En nuestro Centro Penitenciario se ha incrementado el uso, aunque se desconocen los motivos de dichas diferencias.

Cassava flour separation using inverse cyclone
Herrera, Carlos A.;Rosillo, Miguel E.;García, Alberto;
Revista Brasileira de Engenharia Agrícola e Ambiental , 2007, DOI: 10.1590/S1415-43662007000500011
Abstract: in developing countries cassava starch is produced mostly rurally using artisan methods through wet-way processes that consume as much as 37 m3 of water per processed ton. in comparison, the little industrial production consumes 5 m3 of water per processed ton. these waste waters, highly contaminated, are usually discharged in to the rivers without any treatment. with the aim of industrializing the cassava flour production, ciat and clayuca are developing an alternative dry technology, environmentally sustainable, to produce enriched flour as a starch substitute. the intention is to separate the starch enriched flour (< 44 mm) from the fiber rich coarse flour (> 44 mm). the use of an inversely operated cyclone (related to the conventional operation) showed good potential in terms of efficiency and economy. in this paper we propose pressure drop (dp), fines (< 44 mm) recovery efficiency (h), and fines recovery quality (q), as main functional parameters to characterize the apparatus. results show that dp, h, and q only depend on gas velocity (vg) and on the feed solid concentration (c). the h and q magnitudes, approximately 60 and 80% respectively, demonstrate the effectiveness of this technique. potential improvements merit further exploration.

Abstract: Sergio Antonio Rabell Hernández (1933-2000) artemise o, de origen social obrero, se vinculó al Directorio Revolucionario 13 de Marzo y al Movimiento 26 de Julio desde el golpe de Estado de Fulgencio Batista. Al triunfo de la Revolución, se incorporó a las Milicias Universitarias y concluyó sus estudios de Medicina en la Universidad de La Habana en 1960. Cumplió su Servicio Social Rural en Imías, Baracoa. A su regreso a la capital, se vinculó al hospital General Calixto García, donde permaneció hasta el final de sus días. En este hospital, desarrolló toda su actividad profesional como especialista de Medicina Interna e Intensiva, su actividad docente desde Instructor hasta Profesor Titular y su actividad política como Secretario General del núcleo de su área y Secretario del Comité de Dirección del Partido Comunista de Cuba del Hospital. Sus responsabilidades asistenciales y docentes, y su activa militancia revolucionaria no le impidieron continuar su superación profesional y alcanzó la categoría de Especialista de Segundo Grado en Medicina Interna y Doctor en Ciencias Médicas. Su permanente y mantenida contribución al desarrollo científico, la elevación de la calidad asistencial, la labor educativa y la construcción del socialismo en su patria, le hicieron merecedor de varias distinciones y reconocimientos nacionales y extranjeros.
