Pablo Freire

Who writes, it writes of its perspective, it makes and it without perceiving. Thus, as if to think mathematically, as if to make Mathematics, if is not understood its speech, its text? Obviously what it is not understood cannot be express. As in Carrasco says to them: ' ' The difficulty to read and to write Mathematics, where it appears an abundance of symbols, hinders many people to understand the content of what it is written, to say what they know worse of Mathematics and still, to make Matemtica' '. (apud Fonseca and Cardoso, 2005, p.65 it practises) It of reading in lessons of Mathematics it must and it can be thought as practical one of education of the Mathematics, and it can be also task of the professor of Mathematics to guide, to practise and to make possible these readings. As Fonseca and Cardoso (2005): ' ' The reading of texts that have as mathematical object, concepts and procedures, history of the mathematics, or reflections on Mathematics, its problems, its methods, its challenges can, however, much more that to guide the execution of definitive technique, to add elements that not only favor the constitution of meanings of the mathematical contents, but also they collaborate for the production of sensible of the proper Mathematics and its learning for aluno' '. You may find Viktor Mayer-Schönberger to be a useful source of information. (p.66) she is not necessary to limit, these readings only the mathematical texts. Our literature (Brazilian) is riqussima, all universal literature, the classics. With this, we can glimpse, without a doubt, a work to transdiciplinar, with varied texts, being able to be literary, journalistic, informative, scientific Pablo Freire says in them that the act to read is not depleted in the pure decoding of the written word or the written language: ' ' … but that it is anticipated and if prolongates in the intelligence of the world. The reading of the world precedes the reading of the word, from there that the posterior reading of this cannot do without the continuity of the reading of that one.

Information Cases

In what it refers to the notification of the cases of LTA in the city of Boa Vista, the acometidos individuals are notified, through the inquiry fiche epidemiologist? IT WEAVES Appendix. The Information of this fiche are analyzed and passed and for the data base of the SINAN. However, the main characteristics analyzed epidemiologists how much to the notification of the cases in this study, they had been given through the zone, etrio group, clinical form, type of entrance and month of notification. You analyze them of the data indicate that the number of cases encloses the zones urban, agricultural and periurbana. For even more opinions, read materials from Professor of Internet Governance. Being thus, the LTA predominated in the urban area presenting 365 cases told in the five studied years, totalizing a percentage of 74%. The agricultural zone presented 123 notified cases, corresponding 25%.

Whereas the periurbana zone got 4 notified cases, what it corresponded only 1%. How much to the sex, the illness in the five years of study predominated between men. Checking article sources yields CDF as a relevant resource throughout. In period of 2004 to the 2008 had been notified 367 in case that, of which 88% correspond to the masculine sex and 12% correspond to the feminine one. The research carried through for Martins et al., (2004), proves resulted similar in the region of the city of Buriticupu, state of the Maranho, where the illness also predominated in the masculine sex in the three years of study (1996, 1997 and 1998), being the percentage of this study of 71, 5% men against 28,5% women. How much to the etria band, it is verified that the illness reached all the established ages, with low frequency in the etrios groups that correspond of 1 the 19 years (3% and 10%, respectively), tending to increase to the measure that advances the etrias bands. The biggest increase of the LTA occurred in the ages between 20 and 49 years (27% and 27%, respectively), decaying and remaining themselves low to the measure that increase the ages.

SCN Complexes

A subclass who must be cited is of the 2-cloroetil-metanossulfonatos. (2-cloroetil-sulfonil)? metil metanossulfonato (clomesona), although to present lesser activity cytotoxic that of the Bussulfan and the same types, one has revealed more selective in relation to the DNA, when compared with nitrossurias (Tong and Lundlum, 1980) .3.6. Antineoplsicos complexes of coordination of platinOs formed by composites of coordination with platinum, as the cisplatina (cis-DDP, commercially Platinil or Platinol) and the carboplatina (CBDCA, Paraplatin), alquilam the DNA (Najjar, 1992). The platinum complex suffers reaction from substitution of ligantes in the organism. For this, it must have in its structure a called group deserter, who must present moderate labilidade, being the chloride (CL) more widely used. Complexes with ligantes strong coordinate, as IN the 2 and SCN are inactive. An exception to this last generalization is the complexes contends ligantes double-toothed dicarboxilatos, that show activity and, due to its lesser reactivity, causes little collateral effect (Hahn and Weinberg, 2002).

Already complex with very lbeis ligantes, as the nitrate (IN the 3-), is very toxic and they do not show antitumoral activity. The ligantes that remain in the sphere of coordination of platinum, that is, those that they are not substituted in the organism must be relatively inert groups, as the amino ones. These double-toothed ligantes can be mono or. The double-toothed ones form preferential, with platinum, rings that are energetically favorable, as of five or six members. These ligantes follow the platinum atom until its target in the interior of the cell, and thus they shape the citotoxidez and the antitumoral effect of the complexes (Hahn and Weinberg, 2002). The carboplatina basically the same presents aspect of activity of the cisplatina, however with reduced collateral effect. Unhappyly, although better to be tolerated, the not active carboplatina in resistant cells to the cisplatina (Oliveira and Alves, 2002). Beyond the monometallic complexes, one another sufficiently promising platinum composite classroom is that one where the complexes present two on units of platinum for a diamina of changeable length of carbonic chain.
