In the Buddhism, the question still follows the same parameter. The Buddhists understand that the life is a gift of Buddha. The scientific vision does not present that the life has its beginning at a specific moment. But they adopt the Report of Warnock, understanding the formation of the central nervous system as an important aspect for human development (CAMERON; WILLIAMSON, 2005, P. 216). Some authors of the modern philosophy consider that Human being he is that capable one to develop mental abilities that make possible its definition as human. It is the individual reflecting on the individual.

Incapable beings of reflection can not be considered human. (CAMERON; WILLIAMSON, 2005, P. 216) Consideraes Final We assume that the human embryo, since the fecundao, is a human being that has rights and has a moral necessity to respect it. Biology does not teach ethical concepts as the respect and the duty. In against departure, the ethics do not teach biological principles of the human being. Therefore, the union of biology and the ethics is basic for the arrival to a common sense. In this article some points of view in relation to the embryo had been displayed, always considering the vision of the ethics and the religion, that in determined moments, in them takes the least the partial vision of the embryo. But, as the objective of this article is to show the embryo as a human being endowed with possibilities, we consider the reached objective. By means of some arguments, it had the possibility to show the embryo not only as one accumulated of cells, but, yes, a future human being. References LOPEZ, S.G.B. Bio. 5 ed. So Paulo: Hail, 1996.

Study of Queima of the Mineral Coal in Furnaces of Vapor Generators Tdni de Abreu Goulart) Summary the furnace is the component of generating unit of destined vapor to convert the chemical energy of the fuel into thermal energy. In accordance with the type of the fuel, the projects of current furnaces have if alternated between furnaces for burning in suspension, it burns in grate or it burns in fluidizado stream bed. The furnaces of burning in suspension have more including application, mainly for allowing to burning of oil, coal sprayed, or same natural gas. The sprayed coal always if has presented as an advantageous alternative for use in the field of the termoeletricidade. The use of sprayed coal demands some cares special with the stability of flame and its preparation, involving the job of transporting mats, silos, mills and complementary systems of operation. The furnaces adapted with grates or fluidizado stream bed have restricted application the unit of small or average transport and are projected for the solid fuel consumption. The raised leached ashes text of great part of the reserves of fossil coal, together with other less noble fuels, has justified the application of furnaces of fluidizado stream bed, or the adoption of other alternative processes of direct combustion.

This work has the objective to revise these processes of burning and, of this form, to analyze possible adjustments for improvement of the efficiency of the one of the furnace in the direction of if adjusting to the necessities of each particular project in and making possible the burning of the abundant fuel in the south region of Brazil that is the mineral coal. Word-key: Coal, Combustion, Burn, Furnaces. Abstract The furnace is the component of the steam generator that converts chemical energy into thermal energy. According you the type of fuel, to boiler design must be chosen among burning in suspension, grid burning and fluidized bed burning.

Introduction If the HIV is an alive being must obey the Theory of the evolution or this is needing a revision the modern synthetic Theory of the evolution Here part of the principle that is adjusted and looks for to explain the existence of the HIV in base of the evolution. 2.0) Theoretical Referencial 2,1) the environment and the HIV Between individuals HIV inside of a population, that is, inside of a delimited space as the plasma of human one to be contaminated with HIV. 2.2) The HIV and the Theory of Darwin Apresenta a variation in morphology, physiology and behavior. Its children resemble its genitors more than if he resembles the not related individuals, thus one vrion of HIV if he resembles more between itself of what he compares with the adenovirus of the mosquito of the affection, thus is perceived for deduction that presents some similarity. Some forms, what it must be reflected, that has more possibility of survival and reproduction that other forms in determined surrounding. In the case of the HIV for the increasing mortality that is observed, and a great one variability that is observed, the election process is occurring with great force for adaptation of the HIV in the man. Thus to understand the adaptation of the HIV of the chimpanzee it must perceive that the individual level occurs but reaching many because it has that to reach a collective of the entire population of the HIV. A related site: James A. Levine, M.D. mentions similar findings. Therefore to affirm that the HIV is mutant these changes you inherited occur the individual level of inheritance and development and reaches a population that lives pressured in a way, that is the proper man, place where the conditions favorable to the well complex development coexist, dispendioso and ample but to understand the reason of the ample variability of the HIV it must study the filogenia and of history.. might disagree with that approach.
