The Composed Parabolic Collector (CPC) is made up of two parabolic surfaces whose center is the same. In such a center, a black-painted copper tube is placed to transform the sunlight that comes to the copper surface heating it; the CPC concentrates the light in the center, and it can even receive rays with oblique incidence according to its angle of acceptance, the one that could be increased with copper fins welded to the copper tubes. This set also allows to receive and to concentrate diffuse light in a cloudy day. Four Collectors of 1.00 m x 1.25 m are connected to an electrical therma of 500 liters, that will store the water warmed up by the collectors, and through the thermosiphon effect, this one has also has electrical resistance in case there were several non-sunny days.

This article deals with the technical details for the building of a temperate pool with Sun collectors. The so called "tornillo" timber and the CPC Technology (composite parabolic collector) were used for. In the coonections, was to simplify outer ways intent to diminish heat loss. Eight collecting boxes were used with reflectors of shining aluminum foils were used. The purpose is to show a cheaper economical and ecological alternative for users.

In the present paper called “Study of the quality of the water of the basin from the Santa river”, has been studied the polluted effect of the mining passive from Ticapampa that constituted a polimetalic tailing from flotation of sulfide minerals of copper, lead and zinc which has been located in the medium basin of the Santa river, that has been impacted from a negative way since 1900 for mining works of Collaracra, el Triunfo and La Florida; In 1908, by the performance of the Concentrate Plant and the smelting from the Mining Company “THE ANGLO FRENCH TICAPAMPA SILVER MINING CO”, and in 1967, for the mining works from the exploitation of silver, lead and zinc and the performance from the Concentrate Plant in charge of Mining Company Alianza S.A., National Enterprise; as a consequence of the development of mining works and activities of benefiting, there are environment passive,...

En el presente paper denominado “Estudio de la calidad de agua de la cuenca del río Santa”, se estudio el efecto contaminante del pasivo minero de Ticapampa , que constituye un relave polimetálico de flotación de minerales sulfurados de cobre, plomo y zinc, el cual se localiza en la cuenca media del río Santa, la cual ha sido negativamente impactada desde el año de 1900, por las labores mineras de Collaracra, el Triunfo y la Florida; en el año de 1908, por el funcionamiento de la planta concentradora y de la fundición de la empresa minera The Anglo French Ticapampa Silver Mining Co. y en el año de 1967, por la labor minera de la explotación de la plata, plomo y zinc y el funcionamiento de la planta concentradora, a cargo Compañía Minera Alianza S.A. Empresa Nacional; como consecuencia de la realización de labores mineras y las actividades de beneficio de minerales, se tie...
