The present scientific article brings some related boardings on thematic to the heading of the work, with intention to give to the reader basic information on the subject in question. It brings a synthesis of the history of computer science in the education in Brazil, shows necessity and the importance of the formation of the professors in this new digital reality, the benefits of the use computer in the education and educational computer science, and finally, one of the resources currently very used in the construction of the knowledge: the Internet in the education. The methodology used for the development and accomplishment of this work are bibliographical research in books, scientific magazines, articles and sites in the Internet. , Research of field also, and mainly carried through through interview with coordinators and professors, in five public schools of the city of Lizard, focus of this work, that had served of sampling for the survey of the results. The importance of this study, beyond reaching the considered objectives, is also in extending horizontes educational with regard to the existing technological resources, that must more be each time used as aid for the educator in the education process and learning of its pupils. The professor expects that as facilitador, he always searchs to discover new ways for the orientation of its pupils, through the creation of a reflective environment, so that thus, they can assume an active position in the educational and social life, through an efficient education and a learning. The clarification criterion, valley to stand out that computer science in the education treated here, does not aim at the education of contents of the computer science, as computational concepts, principles of functioning or slight knowledge of programming. The insertion of the computer in the process of teach-learning of the curricular contents of all is mentioned to it the levels and modalities of the Education.

Necessary Riser
Gearboxes have after strainer. Typically, the initial pressure ranging from 0.5 to 6-7 atm. Optimal for sanitary measures (3-4 atm) are placed with the built-in pressure gauge. Adjustment is carried out through the hand wheel or screw, available in the gear housing. Some motors are installed in one housing with a filter.
When the pressure in the network is small (below 0.85 atm), we can recommend the installation of the input step-up pump in the apartment, such as UPA 15-90 of GRUNDFOS (Germany) or similar firms to DAB (Italy) or VORTEX and WILO (Germany). But note that setting the pump requires the mandatory approval by the relevant bodies. Correct operation of sewer lines do not require any additional equipment. However, we must remember that the pipe, the outlet drains must be laid with a gradient (1.5-4%) in the direction of the riser. For a sufficiently long tube that can be difficult, because it quietly and not spend a headband you can not hide. It is very difficult create an indentation on the sewer riser (his local break.) This measure is sometimes necessary to 'fit' any instrument in the plumbing box. It is unacceptable that any plots were obtained by horizontal indentation. At the same time a great danger of clogging the riser in your apartment and the collapse of the hydraulic gate devices have lower neighbors.
As a result, litigation costs and triple you provided. The company's specialists 'GALASTAYL' suggestions to create slope on the riser sections of the indentation at least 22,5 . Finally, we note that for mounting plumbing fixtures have been increasingly used special frame design with the necessary fittings (followed by foreign sellers domestic experts were called to install them). These devices accelerate the installation, guarantee quality of systems, but most importantly – make it possible to place devices not only on the walls or in the immediate vicinity, but also in any other place.
