Desde el tiempo de la conquista y colonización en siglo XVI, el territorio argentino fue poblado por especies exóticas entre ellas ovinos y caprinos. El tipo de animal introducido al territorio determinó la formación de poblaciones locales del tipo criollo donde en el caso de los ovinos pertenecían al tipo lanero. En el caso de los caprinos en un principio fueron con escasa cobertura pero existen evidencias de que posteriormente se introdujeron caprinos del tipo productores de cashmere y posteriormente caprinos de Angora. En el caso de los Camélidos estos son autóctonos y jugaron un rol preponderante en los pueblos originarios. Actualmente dichas poblaciones se encuentran relegadas y en manos de pequeños productores en su mayoría aborígenes. En base a estudios previos se puede afirmar que constituyen un material genético de importante variabilidad y de un potencial textil importante. El proyecto pretende continuar realizando relevamientos poblacionales en regiones donde aún se conserva material autóctono o local del tipo criollo con la finalidad de realizar una caracterización zootécnica y genética y así poder evaluar la variabilidad de las poblaciones y proponer estrategias de conservación y/o mejoramiento así como el destino del producto textil producido por dichas poblaciones. El relevamiento comprende un posicionamiento geográfico y breve descripción del sistema de producción, la toma de información biológica, morfológica y zoométrica de al menos el 20% de los animales según el tamaño de la majada o hato y la correspondiente obtención de muestras de fibra. Estas muestras son remitidas al laboratorio de fibras animales de la Red SUPPRAD para su evaluación. Para determinar la variabilidad zootécnica y genética de las poblaciones se confeccionan Índices de arcaísmo o primariedad basados en marcadores fenotípicos, bioquímicos y moleculares. A ello se propone incorporar estudios sobre desempeño productivo y reproductivo de las poblaciones.

One of the main referring subjects to the solar energy is how to compare it economically with other sources of energy, as much alternatives as with conventionals (like the electric grid). The purpose of this work was to develop a software which congregates the technical and economic main data to identify, through methods of microeconomic analysis, the commercial viability in the sizing of photovoltaic systems, besides considering the benefits proceeding from the proper energy generation. Considering the period of useful life of the components of the generation system of photovoltaic electricity, the costs of the energy proceeding from the conventional grid had been identified. For the comparison of the conventional sources, electric grid and diesel generation, three scenes of costs of photovoltaic panels and two for the factor of availability of diesel generation had been used. The results have shown that if the cost of the panels is low and the place of installation is more distant of the electric grid, the photovoltaic system becomes the best option.

In this paper I present some evidencie that forces us to conclude that within the Minimalist Program (Chomsky 1993; 1995), Binding Theory (BT) should be computed after LF (Logical Form). I show that derivations leading to structures containing violations of BT-Principles must converge at LF, since less economical alternative derivations respecting those principles are also ungrammatical. Being irrelevant to the notion of convergence, BT must apply after LF. A similar reasoning reveals that the Theta-Criterion should have the status of a bare output condition appling at LF, since less economical derivations are allowed by the computational system to prevent violations of it.

We present and discuss in this article some features of a research program whose central object of investigation is the way in which the recent fields of history, philosophy, and sociology of mathematical education could take part in a critical and qualified manner in the initial and continuing training of teachers in this area. For that, we endorse the viewpoint that the courses for mathematics teacher education should be based on a conception of specificity through which a new pedagogical project could be established. In such project those new fields of investigation would participate, in an organic and clarifying way, in the constitution of multidimensional problematizations of school practices, in which mathematics would be involved, and that would be guided by academic investigations about the issues that currently challenge teachers in the critical work of incorporation, resignification, production, and transmission of mathematical culture in the context of the school institution.
