El proyecto de investigación "Variables de mayor impacto sobre los indicadores de calidad del agua" se viene desarrollando en la Universidad Cooperativa de Colombia, sede Bogotá, desde enero del 2014. Como resultado de su desarrollo, se llevó a cabo una revisión de antecedentes para identificar aspectos relevantes en el diseño y construcción de un prototipo de software basado en conocimiento que contribuya a mejorar los procesos de gestión del recurso hídrico. El estudio de los indicadores de calidad del agua durante el período de análisis , es fundamental para evaluar la incidencia de variables bióticas y abióticas sobre un fenómeno/ ambiente/área tan relevantes como la calidad del agua. Los autores analizan reportes experimentales suministrados por publicaciones especializadas y organizaciones gubernamentales del orden nacional e internacional. El análisis de la información revisada permitió establecer que una de las metodologías más importante para determinar la calidad del agua es el uso de indicadores ica: herramienta matemática que permite transformar grandes cantidades de datos en una escala de medición única.Palabras clave: calidad del agua, indicadores ambientales, índices de calidad del agua (ica), desarrollo sostenible, sostenibilidad ambiental. Water Quality Indexes: Evolution and Trends at the Global Levelabstract. The research project "Variables of Greatest Impact on Water Quality Indexes" ("Variables de mayor impacto sobre los indicadores de calidad del agua") has been underway is at the Bogotá campus of the Universidad Cooperativa de Colombia since January of 2014. Its preliminary result was a review of precedents to identify relevant aspects in the design and construction of a knowledge-based software prototype that would help to improve water resource management. The study of water quality indexes during the period of analysis is of fundamental importance to evaluate the influence of biotic and abiotic variables on a phenomenon/environment/area as relevant as water quality. The authors analyzed experimental reports supplied by specialized publications and national and international governmental organizations. Analysis of the information showed that one of the most important methodologies to determine water quality is the use of ica indexes, a mathematical tool that facilitates the transformation of large amounts of data into a single measurement scale.Keywords: water quality, environmental indexes, water quality indexes (ica), sustainable development, environmental sustainability.

From1989 on Cynaeus opacus Champion has been found in waste heaps and similar localities in southern Finland together with other synanthropic beetles. Cynaeus is an American genus spreading with man; another species, C. angustus (LeConte), has recently been recorded from Sweden.

stiffness and pulse wave velocity / Aorta and carotid arteries 137 (0.94 to 1.01) p = 0.096; Obesity OR = 0.47 (0.29 to 1.77) p = 0.003 and Diabetes OR = 2.41 (1.15 -5.05) p = 0.020. Conclusions: According to the results obtained, genetic polymorphisms variables were not in the multivariate analysis equation to determine the increase of the PWV, which can be explained either by being included in the selected variables such as hypertension, or on the other hand, they may not have enough strength to remain in the equation. So, according to this study, PWV has much more to do with behaviors and traditional risk factors than the genetic heritage.P883 Endothelial dysfunction, pulse wave velocity and augmentation index are correlated in subjects with systemic arterial hypertension?
