The necessary object of knowledge, some form, to be entailed to ' ' necessidade' ' of the group/pertaining to school community to explain, to understand, to intervine, to move, to foresee, something that defies. Ahead of all these consideraes, we present in this work the accomplishment of a research on Chemical Composites present in the rinds of shrimps and crab, animals of abundance in our city, where its carcasses are plays to the garbage without exploitation. Observing so well its molecular formulas, thus being able to identify to the chemical elements gifts in such structures, understanding as to differentiate the chemical functions gifts. The Quitosana is one two organic composites that we can find in the rinds of these animals and that it comes being studied for the UFC (Federal University of the Cear) in the known sector as PADETEC (Park of Technological Development of the Cear), being this a used chemical substance for scientific, medicinal and commercial ends, where research discloses to its effectiveness in the absolution of ingested fats and reduction of the cholesterol. Of this form we choose pointers adopted for Amaral (2006) referring to this conception as base for our analysis.
According to author, exists the necessity of if working ' ' science as activity humana' '. Of this form, the same one must be presented historically contextualizada, not prioritizing the scene of the scientists, and yes the social-economic-cultural scene, in which its discoveries are carried through, the groups and institutions the one that belong or that they provide ways for its accomplishments. PART METODOLGICA: In view of the objective tracings for this work, we use as methodology the field research. In accordance with Little stream (2002), the inquiry accomplished under the theoretical perspective of the content analysis dimensiona the actions and guides the look of the researcher, allowing bigger understanding of as if of the o process of elaboration of articles of scientific spreading.
Processes of creation For creation of the project had been effected research in the automation areas and software so that the hardware item were identified to which and software would be necessary. The chosen CLP was of the Beckhoff mark. Pioneering company in the supply of technology for automation using a PC or one notebook to twirl its programs. This is allowed on account of the software of programming of language of the called CLP of Twincat PLC.
Twincat PLC allows to work in up to 6 (six) programming languages, amongst them the language of text structuralized used in this project. For supervisory software, a system in the Visual platform Studio was projected that is developed by Microsoft. The Studio Appearance is a tool that allows the elaboration of graphical elements in a screen and that toward ours in case that, it can be come back toward a supervision line, since that adequately programmed. The Studio Appearance allows programming in languages as visual beginner’s all-purpose symbolic instruction code, C#, Java Script, htm and Ajax. Moreover, the Studio Appearance allows the use of the SQL Server. This tool is capable to store information in a data base. The SQL Server supports until 4GB of information. Until 4GB its use is gratis.
Then, to effect the screens of the supervisory one were used language HTML. To allow that the screens were remained brought up to date, the Ajax was used. Link for command buttons (addressing) was gotten by means of C#. The data base is addressed to the SQL Server. 5. Costs and benefits Below are cited values of market of the preventive maintenance and the necessity of purchase of an equipment. These data of table 1 are referring to an electric generator of 12KW supplied by the Thales, a French manufacturer. Stop process
In the first contact with them it was observed that the majority of the educandos was repeating, and that few took taste for the substance sciences, for it to possess many concepts terms that many times are difficult of being remembered. By this reason a way was considered the group to teach the form contents that they could learn what he was being debated in the lessons. Practising the Reading in the lessons of sciences Believing that the reading in the lessons of sciences is a method of assisting the pupils in the understanding of the substance, the work carried through with them during two months used texts that contextualizavam the contents with ours day-by-day, so that they could better understand the subject human body. The professor must have conscience of the necessity of if using methodologies that facilitate to the pupil the attainment of the knowledge, through texts not only brought for the didactic book and yes to go beyond, using reviewed, periodicals and Internet to complement the didactic resources that will allow that educating reflects on a fact or an event, taking them to make it questionings on the boarded subjects in lesson. The subjects worked in this group had been cells, fabrics and digestrio system.
‘ ‘ It is impossible to sensetize the pupils for the reading, if the professor does not have the habit of ler.’ ‘ (HENGEMHLE, 2004, p.136). Being thus it was placed in practical by the educator, what it would be demanded of the educandos, the reading of the materials, searching texts that contextualizavam with the substance that would be given in lesson. 12 taken off texts of sites had been used to introduce the subjects and others had been elaborated with the theoretical recital of each content.
