In the study of holomorphic maps, the term ``rigidity'' refers to certain types of results that give us very specific information about a general class of holomorphic maps owing to the geometry of their domains or target spaces. Under this theme, we begin by studying when, given two compact connected complex manifolds X and Y, a degree-one holomorphic map f :Y -> X is a biholomorphism. Given that the real manifolds underlying X and Y are diffeomorphic, we provide a condition under which f is a biholomorphism. Using this result, we deduce a rigidity result for holomorphic self-maps of the total space of a holomorphic fiber space. Lastly, we consider products X = X-1 x X-2 and Y = Y-1 x Y-2 of compact connected complex manifolds. When X-1 is a Riemann surface of genus >= 2, we show that any non-constant holomorphic map F:Y -> X is of a special form.

Tracking the evolution of research in waste recycling science (WRS) can be valuable for environmental agencies, as well as for recycling businesses. Maps of science are visual, easily readable representations of the cognitive structure of a branch of science, a particular area of research or the global spectrum of scientific production. They are generally built upon evidence collected from reliable sources of information, such as patent and scientific publication databases. This study uses the methodology developed by Rafols et al. (2010) to make a “double overlay map” of WRS upon a basemap reflecting the cognitive structure of all journal-published science, for the years 2005 and 2010. The analysis has taken into account the cognitive areas where WRS articles are published and the areas from where it takes its intellectual nourishing, paying special attention to the growing trends of the key areas. Interpretation of results lead to the conclusion that extraction of energy from waste will probably be an important research topic in the future, along with developments in general chemistry and chemical engineering oriented to the recovery of valuable materials from waste. Agricultural and material sciences, together with the combined economics, politics and geography field, are areas with which WRS shows a relevant and ever increasing cognitive relationship.

A limnological and fish survey program was developed on 112 lakes and reservoirs of Argentina during the summers of 1984 to 1987. Bathymetric surveys with a SIMRAD Skipper 411 model echosounder and line and lead were conducted on more than 40 lakes. This report presents bathymetric maps for seventeen lakes and reservoirs situated in Patagonian Andes Region and Patagonian Plateau betweem 38°53'S and 45°30'S. The bathymetric maps for two reservoirs were made from topographic maps before impoundment. Hypsographic and depth-area curves, and some morphometric parameters are presented for twenty one Patagonian lakes. Mean depth ranged from 2.0 to 111 m. The deepest lakes are situated in Patagonian Andes Region. Colhue Huapi Lake on Patagonian Plateau, is very shallow, having a mean depth of 2.0 m and being 810 km. in surface area.

[ES] El género Sabacon (Arachnida: Opiliones) tiene distribución holártica, y en la Península Ibérica se restringe a Pirineos y Cordillera Cantábrica. Se menciona la presencia de S.viscayanus en la Sierra Cebollera, a partir del hallazgo de una hembra, lo que constituye el primer registro al sur del Ebro. En este trabajo se ha determinado la subespecie a la que pertenece esa población gracias a la captura de un macho, que corresponde a Sabacon viscayanus viscayanus. Con los ejemplares de las colecciones (ZUPV y CRBA) se han redescrito las especies ibéricas y se ha descrito por primera vez el macho de S. franzi. A su vez, se han construido mapas de distribución de todas las especies con datos citados y de las colecciones propias.

El trabajo trata de mostrar los logros en el aprendizaje de la matemática –área de Geometría– a través del contenido transversal Educación para la gestión de riesgos y la conciencia ambiental, usando recursos tecnológicos como Google Maps y Google Earth. El tema desarrollado para tal fin fue el problema sismológico en el Perú. Finalmente, se señalan temas de geometría involucrados, así como temas anexos a través del uso de contenidos de Estadística, Geografía y Ciencias Naturales. La experiencia se hizo con un grupo de 50 alumnas del Tercer año de Educación Secundaria de una escuela pública del Perú.
