Arango,Elkin Fernando; Pati?o,Fredy Alonso; Quintero,Mario Andrés; Arenas,Mónica María;
Colombia Médica , 2011,
Abstract: objective: to assess the levels of physical activity, barriers, and stage of change in an urban population 25 to 50 years of age from the municipality of santa rosa de osos, department of antioquia. materials and methods: a prevalence study was conducted, with a two-stage random sampling among 357 individuals not suffering from any known cardiovascular disease. a pre-designed survey was conducted to assess the levels of physical activity, the stage of change, and physical activity barriers. results: the total low physical activity was 9%, and by domains: work 66.9%, transport 60.8%, household and garden (yard work) 44.8%, and leisure-time 76.2%. the most important physical activity barriers were ?lack of willpower? (70%) and ?lack of time? (46.2%). the most prevalent stages of change were ?contemplation? (40.3%) and ?preparation? (17.1%). conclusion: low physical activity levels were found in different domains of daily life, together with a high prevalence of barriers and stages prior to physical activity practice, mainly among women and obese subjects.

RESULTADOS AMBIENTALES Y ECONóMICOS ALCANZADOS POR CORNARE EN LA APLICACIóN DE LA TASA RETRIBUTIVA EN EL ORIENTE ANTIOQUE O 1997 - 2005
Quintero V. John Fredy
Gestión y Ambiente , 2008,
Abstract: Se realizó un compendio del desarrollo del programa de tasa retributiva ejecutado por CORNARE desde 1995 hasta 2005, en el que se visualiza la gestión ambiental en el proceso de implementación, evolución y resultados ambientales y económicos, a través de la reducción de la carga contaminante vertida a las fuentes hídricas superficiales en términos de DBO 5 y SST, como en la destinación de los recursos financieros obtenidos por esta tasa, los cuales ascienden a 11.600 millones de pesos en el período evaluado, y, en su gran mayoría, fueron destinados a cofinanciar proyectos de saneamiento básico municipal. Podrá observarse que en el sector privado, se han tenido mejores resultados en la reducción de la carga contaminante, y que los municipios aportan la mayor carga generada y vertida sin tratamiento, especialmente los de alta densidad poblacional y ausencia de Planta de Tratamiento de Aguas Residuales, PTAR, como son algunos de los pertenecientes a la cuenca del Río Negro. En general, comparando el a o 1997 con el 2005, hubo una reducción semestral relativa de carga contaminante para toda la región de CORNARE del 24% para DBO 5 y 35% para SST.

Abstract: Algunas especies del género Phyllanthus han demostrado actividad frente al virus de la hepatitis B in vitro e in vivo. En este trabajo se evalúa la capacidad de inactivación sobre el AgsHB de un extracto acuoso de la especie endémica Phyllanthus orbicularis. Se analizaron 4 concentraciones del extracto (100, 50, 25, 12,5 mg/mL) frente a 34 sueros positivos a este marcador. Todas las concentraciones ensayadas mostraron la capacidad de disminuir el valor de densidad óptica en más del 60 % de los sueros tratados, mientras que el por ciento de sueros que se convirtieron a negativos fue de 88,2 %, 97,1 %, 50 % y 8,8 %, respectivamente. La concentración de 12,5 mg/mL no mostró diferencias estadísticas con respecto al grupo control; mientras que las concentraciones de 100 mg/mL y 50 mg/mL, las cuales no se diferencian estadísticamente entre sí, fueron las más efectivas. Estos resultados muestran que el extracto acuoso de P. orbicularis presenta uno o varios compuestos capaces de inactivar in vitro al AgsHB.

Abstract: Objetivo: Determinar la frecuencia de la depresión en un grupo de jubilados participantes en programas de actividad física y/o asociaciones de la Universidad de Antioquia. Materiales y métodos: Estudio descriptivo transversal realizado durante los meses de abril y mayo de 2005. Se seleccionaron 100 jubilados por conveniencia entre los participantes en programas de actividad física y/o asociaciones de la Universidad de Antioquia, Medellín-Colombia, 50 hombres y 50 mujeres con una edad promedio de 65.7 a os. Se aplicó la Escala de Depresión Geriátrica de Yesavage y se indagaron algunos aspectos demográficos, económicos, funcionales, afectivo-familiares y de utilización del tiempo. Resultados: Se halló una depresión total del 6%. Los valores más altos se encontraron en mujeres, en quienes tenían menor tiempo de jubilación, en quienes no desempe aban actividades laborales después de la jubilación, en los que percibían como mala su situación económica y entre los que no hacían ejercicio físico. Se encontró una asociación estadísticamente significativa, principalmente entre la depresión y la percepción de la situación económica como mala (p< 0.05). Conclusiones: La depresión en las personas estudiadas es inferior a la de otras investigaciones, situación que puede explicarse por el muestreo utilizado y, posiblemente, por un factor protector común, la pertenencia a grupos.

Abstract: the present study concerns the synthesis of zeolites from neogene sedimentary and pyroclastic rocks exposed around the sochagota lake, paipa (boyacá). two synthesis methods were used: conventional hydrothermal treatment and alkaline fusion followed by hydrothermal reaction. both raw materials and synthesised zeolytic products were characterised by x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir) and nuclear magnetic resonance (nmr). several zeolytic phases were synthesised, including faujasite (fau), phillip-site (phi) and sodalite (sod). the results showed that the alkaline fusion approach was more efficient regarding hydrothermal conversion of the raw materials than conventional hydrothermal treatment, taking into account that zeolytic products having a higher degree of crystallinity and few impurities were obtained in this way. this study was aimed at applying experimental mineralogy to a laboratory simulation of the geological conditions in which zeolites can occur as the basis for defining criteria for exploring natural zeolites in colombia, with prospects for the profitable exploitation of these mineral resources in different parts of colombia.

Abstract: Los sistemas integrados de tratamiento de aguas residuales buscan la disminución de materias orgánicas y nutrientes, además de la reutilización de los subproductos generados en el proceso. Para complementar la eficiencia de remoción de nutrientes del actual tratamiento de las aguas residuales de la Universidad Pontificia Bolivariana Bucaramanga se construyó un modelo piloto integrado con Spirodela sp., el cual fue evaluado para medir la eficiencia en remoción de nutrientes (nitrógeno y fósforo), coliformes totales y fecales, con diferentes alturas de lámina de agua; los resultados reportaron eficiencias hasta de 77.07% para nitrógeno amoniacal, 97.10% fósforo total, 98.56% coliformes fecales y 96.4% coliformes totales. Palabras clave: aguas residuales, tratamiento biológico, remoción de nutrientes. Integrated residual water treatment systems try to reduce organic matter and nutrients and reuse by-produets generated during the process. An integrated pilot model was constructed with Spirodela sp. to complement the Bolivariana University's current residual water treatment plant's efficieney in removing nutrients. This was evaluated for its efficieney in removing nutrients (ammoniacal nitrogen and phosphorus) and total and faecal coliforms using different depths of water. 77.07% efficieney was obtained for ammoniacal nitrogen, 97.10% for total phosphorus, 98.56% for faecal coliforms and 96.4% for total coliforms. Key words: biological treatment, residual water, nutrient removal.
