Perrotti Cultural

In accordance with Perrotti (1990, P. 15), a necessary comment mentions the culture concept to it, perhaps because it brings more problem that the child concept. What it interests is to question a conception of culture and cultural process for children. Of implicit or explicit form, always an equivalence between culture and cultural product is established, reducing the first term to as. Culture appears as the result of a process, the social inheritance. The cultural products would be expressions in a definitive way of life that, while such, if explains and if it justifies. To think the formation of the child under the optics of a capitalist society implies to perceive the necessity to reflect concerning the influences that social division of the work and the relations of social classroom exert on the educative process. In accordance with Fonseca ' ' …

In this model the bourgeois children are instrumentalizadas to direct the society and of the diligent classrooms they are formed for trabalho' ' (2004, P. 19). Thus, the child would socially assume the role of consumer of cultural goods taxes; the culture only finishes of a banalizada form serving as domination instrument and fits to the proper child the incumbency to assimilate and to adapt it the molds and standards established for the society. In the vision of Perrotti (1990), the world of the child suffers, in result of this change in the habits of the families, fatal consequences. What it was vital was, little by little, taken: the yard, the street, the garden, the square, the fertile valley, the free space. This taking of the Real tries to compensate with the symbolic one. It remains, therefore, to prevent boardings that treat the cultural production for children as necessity, remedy for males of the world. Thus the vision of cultural production for children, while one adjusts a necessity to it of the economic system in if reproducing, despite it is to the cost of the death of the playful one, of the pleasure, the creation, the adventure of the dream and the meeting in the diverse phases of educating.

Parallel Universes

Who appreciates the literary sort and cinematographic the fiction-scientific one certainly it remembers some referring narrative to the parallel universes. It occurs that, depending on the eventual results gotten in the fields of the comment and the experimentation, the coexistence of many universes can leave of being ' ' fico' ' to become &#039 purely; ' cientfica' '. The Theory of the Parallel Universes was presented to the world, for the first time, as academic thesis in middle of the decade of 1950. In virtue of its eccentricity, it finished for being ridicularizada in the subsequent decades, until, recently, its beddings had passed to be studied empirically: scientists had observed that substance microparticles, when observed, the known and possible states tended to modify its structure physical for all. Such constatao opened the doors for the acceptance of the initial academic hypothesis.

If substance microparticles if convert into all the physical states known and possible, great structures of substance, without and with life – including the being-human beings – make also it, unfolding itself in innumerable versions. This means that, since the beginning of the call ' ' multiverso' ' , with the explosion of the big-bang, everything what it can happen, in accordance with the laws of the physics, effectively occurs, and not only one of the possibilities. Thus, to each minimum unit of time we would have the creation of millions of ' ' bubbles of realities alternativas' ' , that they are the parallel universes (the famous Theory of the Bubbles, that coexist inside of the multiverse). Our universe, therefore, would be only one of these bubbles. In such a way, for example, it would have parallel universes where our galaxy was not formed; others where only our solar system did not arrive to exist; some where it consisted, but the life in the Land did not prosper because the precursory microorganisms had died; several where the Man of Neandertal was extinct for climatic catastrophes, and, therefore, the Homo Sapiens-Sapiens did not arrive to exist; one handful in which Gnghis Khan, when enslaved of infancy, it died of exhaustion; groups where Germany won World War II, or in which that the plans to knock down the Twin Towers previously had been aborted, and, consequently, it did not have the current War of Iraq; another one where you, who already passed for a situation where it was between the life and the death, effectively died, in way that you are your proper surviving version; e, also some where the proper theory argued here already was proven.

University Coal

If of the one in furnaces, ovens and boilers, being the main used techniques the combustion in grates and the combustion in fluidizado stream bed. In the combustion in grate, the coal in the sprayed form is used, the coal is burnt in a fixed stream bed on a grate, through which the combustion air is blown. The main disadvantage of this system is in relation the short speed of burning due to low specific surface of coal particles and the limited thickness of the layer of coal in the grate. In the combustion in fluidizado stream bed, the coal is burnt in a stream bed of particles kept in a state of fluidizao for necessary air for combustion. Some advantages of the process of combustion in fluidizado stream bed are better efficiency in the combustion, power to burn little combustible, high taxes of heat transference. Air is blown of low for top in a vertical duct.

The worn out coal is played in the draft and the particles are in suspension, if holding as a fluid, therefore the name of fluidizado stream bed. 8 Comparison of the types of burning for the mineral coal Between the boilers most used for burning of mineral coal we must detach the boilers that use the methods of burning with sprayed coal and fluidizado stream bed, the boilers of fluidizado stream bed as BASU (2006) if basically characterize for the capacity to vary the types of fuels that are being burnt, without causing problems, have one high efficiency of combustion and low emission of harmful gases, already the boilers of sprayed coal if limit to an only type of coal, and have its good one limited exploitation the use for burning of a coal with baixssimo leached ashes text, something around 10% of leached ashes text, when compared the boilers of fluidizado stream bed it the same has low an efficiency in the combustion for type of coal. Analyzing the characteristics of the mineral coal of the region comparing the advantages and disadvantages between these two types of boiler and its methods for burning of the coal, are clearly that optimum type of boiler for burning of the coal of the region is the boilers with fluidizado stream bed, had the fact of our new, very dirty coal to be very and with high leached ashes text. Consideraes Final had been analyzed differences between the combustion of the coal in grate, combustion of the method with sprayed coal, used during much time, and the combustion in fluidizado stream bed. Knowing the differences between these methods, we can say that the process in fluidizado stream bed, possesss one I number considerable of advantages, mainly when related with the mineral coal of the south region.

Had to the fact of the coal of our region to be young, many research is being developed so that it thus has an improvement in the technologies for burning of the coal and being able to generate a sustainable exploitation of the same.
