The Mechanism

Depending on the manufacturer and model of such a mechanism can be equipped with rollers to facilitate sliding block of seats on the guide and the rear backrest, which will protect you from contact with the cold wall. Typically, the model with the mechanism of "" have a spacious linen compartment, which is especially valuable in cramped housing conditions. Another very popular mechanism – the "book". Previously, it was probably the only commercially available mechanism is not without drawbacks, however. The main disadvantage of "books" was that due to peculiarities of production in the unfolded form of her bed was uneven (at the junction of the seat and spinochnoy formed part of a fairly deep "trough", which could compensate for only quite thick mattress). Also, in order to expand the "book", it was necessary to keep away from the wall 10-15 cm, or each time before unfolding to move it from the wall, because high back for it hurts.

Fortunately, there also was not without technological progress. Now the classical mechanism "book" is often complementary to the rollers on the legs that allows it to move across the floor without prejudice to the latter. On the basis of this mechanism with the development of technology appeared mechanism of "click-Clack." It differs in that in addition to the back end position "sitting" and "lying" can take the intermediate position-"half-sitting" and "recline." Different manufacturers of the mechanism of the provisions of the backrest varies from 3 to 5. There are models, which in addition to the mechanism of "click-Clack" also contain an additional mechanism for "automatic rollback of the Wall," which allows to put the sofa against a wall and it does not stop when unfolded.

Eletronuclear

Summarizing, the happened energy of nuclear plants is today ' ' more limpa' ' (4) that those happened of others any sources, amongst them the termeltricas plants the aeolian gas and oil or .(5) In ours to understand, with the implantation of nuclear plants we will only be capable of at least balancing the system of electric energy in Brazil. Unhappyly, this taking of decision, through the retaken one of the Brazilian nuclear program, not yet left the paper. In the year passed, the government of former-president Lula and Minister of Mines and Energy, Edison Lobo, motivated for the relations on the subject with the Anger, had given beginning to the research of implantation of nuclear plants for such ends in the Bahia, Alagoas, So Paulo and Minas Gerais. Through a proposal raised technique, four States had appeared as the best places to install plant of this type. The study it fit to the Eletronuclear and the beginning of the workmanships, was entailed to the endorsement of the Presidency of the Republic.

Occurrence this or not, so far the encouraging consideraes remains ' ' letters mortas' '. As this saving project, each new constructed plant would have capacity to generate a thousand megawatts of energy. So that let us can have an idea of this value, for comparative ends: – the national portion of the Plant of Itaipu generates 12 approximately a thousand megawatts of energy, but the Brazilian deficit, as Bolivar I still catch is remained .(6) Is imposed, therefore, as immediate and inadivel necessity the dissemination of this monumental project for all the domestic territory. So that if it moves this mentality arraigada in the unconscious one of the Brazilian population has necessity of that this is informed, instructed and qualified in recognizing its rights and obligations concerning the benefits that the production of nuclear energy imposes. For first, it will have necessity, however, of if trusting the defense of the social rights through a proper, Brazilian, perfected and healthy right nuclear, of specialists in the sector who effectively defend the Brazilian population, with its characteristics, directly involved in the projects.
