The purpose of this essay is to briefly evaluate the relationship that exists between media and literature in a general approach. The referred cases are exemplary in character. We suggest that there are essentially three ways by which medialiterature relationships come about. The classification provided herein seeks to contribute towards more detailed studies on this matter and invites to reflection.

This article is based on the results of an experience with training undergraduate and postgraduate communication students for media education. The activities were founded on the theory and practice proposed by British researchers. It was found that many participants held a fragmented knowledge on the subject, permeated by theoretical and mainly methodological doubts.

The use of digesters has become an important alternative for the proper disposal of organic agricultural wastes, serving as a solution to some environmental and health problems. Furthermore, the process of digestion provides commercially valuable by products such as biogas and bio fertilizer. The generation of biogas from agricultural waste, and its use in power generation systems has aroused great interest in rural areas because it enables supply in whole or in large part the energy demand of ownership by reducing production costs. The advent of technology has brought new forms of energy conversion of biogas, as the use of micro turbines specifies to be fuelled with biogas derived from the decomposition of organic matter in digesters, since it has a low level of methane in its composition, and high degree of impurities such as hydrogen sulphide, which are harmful to equipment and reduce the calorific value of biogas. The use of micro turbines behind other advantages like low emissions, great fuel flexibility and low maintenance. This paper presents an analysis of the feasibility of using biogas generated from cattle manure in micro turbines to generate electricity. Behind also an assessment of the energy potential that each animal has on various uses of biogas, and forms of energy recovery from the exhaust gases of the micro turbine. Also conducts an evaluation of the energy savings that the use of biogas aggregates properties.
