National Congress

Already it was proven scientifically that the proteins manipulated in laboratories are not harmful to our organism (unless the individual presents some type of allergy to substances used for the attainment of G.M). We know that man has much time comes using the natural resources renewed and you did not renew indiscriminately. Daqui to some years with the disordered geometric growth of the population and the disequilibrium of the ecosystems as we will go to supply our alimentary necessities? Now, with the regulation of the use of the cell-trunk in research with carrying people of diverse anomalies Brazil one more time obtains to give plus a step and tries not to be so behind some countries of the first world. The first victory was in the National Congress, after that it came the support of public people and entities interested parties, solidary to a so delicate and important question.

Exactly knowing that the results alone will be gotten in the long run and that the resources offered for these research still are few we have that to more look each time keeping informed in them stops in the future who knows to charge or to question? So that the people who work seriously with the Biotechnology are respected and have its recognized work is essential that our diversified genmicas libraries are each time more and that the professionals are if specializing. Who knows daqui to some years instead of taking vaccines injectable will be able to ingest its content inside of determined fruit, cereal or vegetable? So that all the procedures inside of the Biotechnology are accepted for the society are necessary a bigger severity on the part of the competent agencies, as the creation of more commissions of Ethics, investments in Biossegurana and dynamic that make possible greater spreading of methodologies and carried through results of the works and research. Also it is necessary greater transparency indicating of clearer form to the population on the processes of technological manipulation in the labels of foods to be commercialized. The reformularization of the Laws for the collect of taxes and the regulation of the commercialization of these products and foods is another initiative that needs to be seen with bigger severity for the competent agencies. Aristotle (384-322 C) affirmed that ‘ ‘ Sciences have bitter roots, but the fruits are doces’ ‘. Andra Karla Sobreira Almeida?

However, inside of our vision of process, this is permissible. At a first moment, we use the Internet as tool and its characteristic marcante than is the access to the information. Therefore, the computer must be used as a learning instrument, where the pupil acts and participates of its process of construction of knowledge of active form. (MAGELA, 2008) After a maturation process, we perceive that the Internet is more than this: we start to use it as a net communication. We start to participate of projects and world-wide colaborativos events, to participate of Lists of Quarrel which we debate and we change experiences and to use it with expression tool social politics and.

RESULTED the gotten results they condisseram with the research carried through until the moment, and that already they were waited. The pupils who had had lesson in the computer science laboratory (lesson given with the equipment aid of YOU) the other pupils who had had lesson in the classroom, without any equipment aid had had an income the top of the average comparing them it. Thus proving the effectiveness of these inserted equipment in the process teach-learning. CONCLUSION I conclude that computer science is of utmost importance for the incentive of learning of the pupils, for being an efficient and seemed methodology with our reality, our daily one. It is important to stand out that no technology will substitute the professor or books, however is through these used technologies that the percentage of assimilation and perception raises the capacity of retention of knowledge of the pupils. Exactly with the proven effectiveness already of the resources multimedia, many schools in Brazil not yet use of its laboratories of YOU, these schools, of majority of the state, they do not use of these equipment for not having adjusted professionals to give to dynamic lessons front to these technologies or for having unprepared professors technical for the equipment manuscript of computer science or for being a mere transmitter of information.

Corrosive Electric

Usam condensing in diverse points of the amplifiers, to connect signals of floors for others and to deviate signals for the mass. Capacitive Reactncia When connecting itself a condenser in a source alternated, each change of tension causes to load or discharge of the condenser, provoking the circulation of a chain. The opposition that the condenser presents to the ticket of this chain under regimen AC, is known as capacitive reactncia, and the same one varies as varies the frequency of signal AC. The capacitive reactncia is given mathematically by: Where XC = capacitive reactncia, measured in ohms f = frequency of signal AC, in Hertz – Hz C = capacity measured in Farads – Dielectric F a dielectric or electric insulator is a substance that possesss high Resistance to the flow of the electric chain. This to play its function correctamente, is chosen through certain requirements, such as: Elevada resistance electric, to guarantee the isolation between the part and the electrode; elevado to be able cooling therefore this must cool the part and the electrode, since the extreme heating can originate fissuration; steady Viscosity therefore must evacuate particles of the zone of cut with effectiveness; Not toxic not to free you substantiate toxic when displayed the temperatures high; Filtrabilidade; to keep particles in suspension facilitating the posterior filtering; Elevado latent heat, therefore must be resistant the high temperatures and the oxidation preventing the degradation; Corrosive No not to corrode the constituent components of the machine; transparency to facilitate the visualization of the work zone. Applications the USA in capacitors to prevent the risk of the plates to enter in contact, for moreover any substance submitted to an electric field can be ironizar and become a conductor.

The USA in handles of powers and RF. Polarization of dielectrics. Notion of the electric field in the substance the dielectrics (or insulators) are those materials that cannot lead electric chain, Nor can be loaded for induction.

The Electric

For the opposite to the conductors, in these materials it does not have free loads that they can be put into motion with easiness. But the dielectrics also are Constitudos of loaded particles (the electres and the protes). An electric field (external), in the presence of a body insulator, also is modified, even so in different way of what he was a conductor. Let us consider a condenser of plates parallel bars, isolated and loaded with a load Q. Let us full the space enters the plates with an dielectric material, for example, wax, to measure d.d.p now enters the plates of the condenser, we go to see that it diminishes comparing with the situation without wax. However, the stored load does not modify, does not have load movement through the wax layer. Then, the electric field in the condenser diminished due to presence of the wax.

Let us introduce a parameter, called constant dielectric that describes the attenuation of the electric field in the wax layer. Mathematically express in the following way: E= That is, the dielectric constant of a material insulator says how many times weakker are the electric field in this material comparing with the one in the vacuum. As the electric field in the condenser he is homogneo, we can say that the definitive constant through the relation (75) is, of fact, a parameter of the material (in this in case that, of the wax) and does not depend on the geometry or the sizes of the body insulator. Then, the electric field in the material insulator is times weakker of what in the vain emptiness: = This must it the fact of that in a external electric field, the insulator is polarized, that is, appears a induced polarization in the material. Many material insulators are constituted by atoms (or for molecules) that they have not null a dipole moment. As we know, a doublet has trend of to line up itself with the external electric field,

Educational Researcher

Some had seemed to be something bothered by not operacionalizarem in way more concrete the tasks that could carry through in the future with its pupils. One is about a very common concern, that they bring for discipline them to all in this phase of its formation and relation which would be premature to give the type of answers that they desire. The educative use of a powerful way as the Internet has of being equated in function of the concrete pupils, the real conditions of work and the pedagogical project of the school and the group to discipline where the professor if inserts. Moreover, the future professors had developed new perspectives on the use of TICs in the mathematical education and some appreciation for active methodologies of work to promote the learning. Both are important aspects of the necessary professional knowledge for the education of the mathematics. The TICs only tools auxiliary of the work are not.

It is a basic technological element that of the form to the social environment, including education of the mathematics. As such, they influence the evolution of the knowledge and the professional identity of the mathematics professor. The future professors need to develop confidence in the use of these technologies and a critical attitude in relation they. They need to be capable to integrate them in the purposes and the objectives of the education of the mathematics.
