Luchas por la salud en Colombia.: Una propuesta teórica para su análisis
Borrero-Ramírez,Yadira Eugenia; Echeverry-López,María Esperanza;
Revista Gerencia y Políticas de Salud , 2011,
Abstract: this is a theoretical research that proposes the convergence of three strands for the study of struggles for health in colombia starting from the analysis of sociopolitical structure and the actors. this goal involves a question on the existence, if any, of collective action for health, framed by the reform and in a sociopolitical violence context. the method used was documentary analysis of two kinds of sources: 1) examination of academic works on collective action and social movements, and 2) papers on social struggles in colombia. the results show that struggles for health are immerse in other struggles, even if the reform promotes the creation of new actors and protest forms and the path to the claim of the right. as a consequence, complementary theoretical approaches that show the structure while showing the actors are needed.

Abstract: bogotá city traffic has been having progressive circulation constraint measures and a new determination was taken in january of 2009 which banned the mobilization of 40% of the private cars during working days. this research evaluated the traffic noise in one of the most important avenues of the city because of this measure and the no car day. with the new restriction, neither vehicles nor traffic noise, showed decline, however, during the no car day there were more public vehicles (buses and cabs) and consequently, higher sound pressure levels, which are upper the norms and represent a healthiness public problem.

Abstract: this paper presents a study to determine the effect of series facts (flexible ac transmission systems) on steady-state voltage stability, for different operating conditions of the power system. for this study, the simulation software neplan is used for modeling facts in the ieee300 power system. this power system is changed slightly to comply the operative constraints and apply the proposed location methods for facts devices. to determine the effect of these facts devices, a contingency analysis is carried out with the maximum and the reduced chargeability, and the voltage stability analysis using modal analysis and pv curves. finally, it presents a comparison chart of eigenvalues and voltage stability margin results using series facts devices.
Efecto de los FACTS serie en la estabilidad de voltaje de estado estacionario

Ingeniería y Desarrollo , 2009,
Abstract: Este artículo presenta un estudio del efecto de los FACTS (Sistemas de transmisión en corriente alterna flexibles) serie en el mejoramiento de la estabilidad de voltaje de estado estacionario, para diferentes condiciones de operación del sistema de potencia. Se utiliza la herramienta computacional NEPLAN para modelar los FACTS serie sobre el sistema de potencia estándar IEEE300, modificado levemente para cumplir con las restricciones operativas y ubicar los dispositivos FACTS. Para determinar el efecto de estos dispositivos FACTS se realiza un análisis de contingencias, se determina la cargabilidad máxima y reducida del sistema de potencia, y se efectúan los estudios de estabilidad de voltaje utilizando las técnicas de análisis modal y las curvas de potencia vs voltaje (PV). Finalmente, se presenta una tabla comparativa de los resultados de los dispositivos FACTS serie, utilizando como índices de evaluación los valores propios y el margen de estabilidad de voltaje del sistema de potencia.je.
Importancia de la biología molecular para la Fisioterapia moderna
Ramírez Ramírez,Carolina;
Revista de la Universidad Industrial de Santander. Salud , 2011,
Abstract: a profession can be improved through the development and application of scientific and technological advances around the issues relating to their expertise. recently, the deciphering of the genetic code and human genome sequencing creates the basis for the development of methodologies and techniques of molecular biology. these resources have allowed a deeper understanding of the human tissue structure and function, and intervention mechanisms used by health professionals. physiotherapy uses physical modalities affecting the tissues of the body, for that reason, molecular biology offers professionals a better understanding of the effect of these types of interventions implemented in different tissues. thus, the physical therapists should be aware about the importance of this basic science and its clinical use in everyday problem solving that generate a new evidence-based practice to contribute to professional development. salud uis 2011; 43 (3): 317-320

Importancia de la biología molecular para la Fisioterapia moderna Importance of molecular biology for the modern Physical Therapy

Abstract: Para que el cuerpo de conocimiento de una profesión crezca y se fortalezca debe estar al día con los avances científicos y tecnológicos que surgen continuamente para incluirlos en el repertorio de recursos que usa para la investigación de problemas específicos de su saber. Recientemente el desciframiento del código genético y la secuenciación del genoma humano creó la base para el surgimiento de metodologías y técnicas en el área de la biología molecular, las cuales permitieron profundizar en el conocimiento de la estructura y función de los tejidos humanos y también mejoraron el entendimiento de los mecanismos por los cuales actúan formas de intervención usadas cotidianamente por profesionales en salud. La Fisioterapia utiliza modalidades físicas que interactúan con los tejidos corporales, por ello la biología molecular permite un mejor entendimiento de los efectos que las dichas modalidades generan en el tejido sobre el cual son aplicadas. Por tanto el objetivo de este artículo es reflexionar sobre la necesidad de que el Fisioterapeuta se apropie del conocimiento en ésta área de las ciencias básicas, usarlo como herramienta para la solución de preguntas relevantes de su quehacer clínico y así contribuir de manera efectiva con la generación de nuevo conocimiento que promueva la práctica basada en la evidencia y fomente el crecimiento de la profesión.

Abstract: En la medida en que crece la preocupación por mantener y mejorar la calidad del medio ambiente y proteger la salud humana, organizaciones de todo tipo están enfocando cada vez más su atención hacia los impactos potenciales de las actividades que realizan para la generación de productos y/o prestación de servicios. El desempe o ambiental de una organización es de gran importancia para los clientes internos, externos y las partes interesadas. El logro de un desempe o ambiental razonable requiere de un compromiso de la organización, para un enfoque sistémico y un mejoramiento continuo de su Sistema de Gestión Ambiental (SGA).

Abstract: in this study, we scanned multiple published databases of gene expression in vivo of m. tuberculosis at different phases of infection in animals and humans, to select 38 proteins that are highly expressed in the active, latent and reactivation phases. the selected proteins were predicted for t and b epitopes. for each proteins, the regions containing t and b epitopes were selected at the same time to look for identical epitopes on m. smegmatis based on sequence alignments. preliminary studies of humoral immunogenicity and cross-reactivity with m. tuberculosis in mice using two m. smegmatis-derived experimental vaccines were carried out, demonstrating the immunogenicity of m. smegmatis proteoliposomes and the recognition of m. tuberculosis proteins by the sera of animals immunized with this vaccine candidate. the conjunction of in silico and in vivo studies suggested the potential for future evaluation of m. smegmatis as vaccine candidate against tuberculosis using different strategies.
Inflation, Monetary Policy and Economic Growth in Mexico. An Inverse Causation, 1970-2009  [PDF]
Eduardo Loría, Jorge Ramírez
Modern Economy (ME) , 2011, DOI: 10.4236/me.2011.25093
Abstract: It is demonstrated through an Structural Vector Auto Regression (SVAR) model which distinguishes short and long term effects, that the monetary policy implemented in Mexico (1970-2008) has been successful in reducing inflation at the cost of stagnation, especially after 2002. Inflation Targeting is contradictory in itself because, while it is efficient in improving transparency and credibility of the monetary policy, it does not solve the structural causes of inflation and conversely, increases the financial costs of economic agents.
