Morphometric characteristics are quantitative indicators of basin elements, which influence the magnitude and variability of hydrological processes. The main objective of this work is to determine morphometric parameters related to the geometry, relief and drainage network of 34 subbasins located in the WEST of Mendoza capital city (Argentina), between parallels 32° 55' and 32° 58' S and meridians 68° 53' and 69° 05' W. This information will allow understanding and characterize the hydrological processes in the eastern slope of the Precordillera, Piedmont and Mogotes low hills range. Based on previous cartography, a base map was made, where basins were delimited, riverbed and level curves were digitized and the dimensions of basins and hypsometric bands were subsequently determined. In this way, the basic information was obtained from the calculation of the shape indexes, hypsometric curve, height and mean slope, network parameters and Horton's laws. A Geographical Information System (GIS) has been used for the delineation and calculation of the morphometric parameters of the basins, using free software GvSIG. [ABSTRACT FROM AUTHOR]

The skin is the appropiate organ to administrate active principles in orden to obtain local or systemic effects. Formulations for topical use most common are: lotions, emulsions, suspensions, creams, ointments, which must gather certain conditions to be applied to the skin. In this work, the objective is to select an emulsion prepared by a technique of liquid crystals formation composed by stearic acid, mineral oil, triethanolamine, propylparaben, methylparaben and water. To this formula we incorporated a pharmaceutical active liposoluble ingredient: econazole. Econazole, a principle active with topical administration and local action, is a substance soluble in oils, which stays in the liposoluble fraction of the liquid crystals and in their internal phase of the emulsion without modifying their rheological profile not even the stability of systems. Besides the HLB of the systems and their rheological behaviour we also study the presence of liquid crystals with polarized light, the existence of secondary drops with common light and systems stability by centrifugation, thermal stress and temperatures of 40 °C. The values obtained from the studies made, demonstrated that the emulsion achieved present a rheological profile and stability conditions suitable for medicinal use cream. [ABSTRACT FROM AUTHOR]

This article presents and develops some of the edges on working of the guerrilla that emerge in the memories of the former militants of the armed organizations in Argentina. Beginig from this journey we will have access to the registration that one has presently on it, which will allows us to establish part of the subjective environment of the moment, the main characters consideration of the activism and their significance in the general context of the militancy.

The first part of this text raises the need for an up-to-date and more comprehensive understanding of the concept "freedom of speech"; one that takes into consideration a real praxis and not a mere legal notion; one that takes into account new technological determinants and the contemporary connotations of the term "speech". The results of the above-mentioned work are then applied in the second part of the text, where the real state of 'freedom of speech' in Venezuela, 2007, is described. At the moment, Venezuela is undergoing a rapid political evolution where freedom of expression, even if still respected de jure, is gradually less respected de facto. This section includes a brief empirical description of what could be called the 'state of the affairs', an analysis of the new balance between access and participation, plus a final analysis regarding the operative application in Venezuela of Article 19 of the Universal Declaration of Human Rights.

The article discusses two points related to freedom of expression and touching upon the closing of RCTV by the Venezuelan government. The first point is that freedom of expression has been around for hundreds of years and has appeared in political documents dating as early as 1989 in the Virginia Declaration of Human Rights. The second point is that not only does freedom encompass what people say, but also includes access to different sources of information, of content, and of interpretations.
