Flocculation

Aiming at overcoming of these limits, some industries treat its effluent ones through the advanced oxidativos processes (POA), characterized for the generation of oxidantes species, strong mainly radical hidroxila (OH.). Among these processes they are distinguished, beyond the treatments that use the iron of valence the zero and ozone, Photo, that consists of a reaction between Fe2+ and hydrogen peroxide (H2O2), a sufficiently unstable molecule, resulting in the radical hidroxila. This, in turn, reacts with the corante, unchaining the deterioration of the last one. Treatments as absorption, flocculation, chemical degradation, electro and/or photochemistry and biodegradao, information extracted in visit technique company HJ Meshes? Brusque? SC day 20-09-2010. The absorption consists basically of the ticket of the effluent ones in ' ' barreiras' ' of diverse materials, as silica-gel, bauxite, active coal, among others; not being very used had to its high cost.

The chemical degradation is based on reactions with chlorine or ozone, preferring itself this last one for not leaving residues, is a used process in great volumes of tributaries due its rapidity and economy. As the majority of the industries is of small average has carried this process finishes being of side. The Flocculation nor always is used by having resulted that they vary very depending on the used corante, of the concentration of the rejeitos and the presence of catalysers. The catalysers can facilitate the withdrawal of the pollutants, but these by itself are pollution sources. In the method of the biodegradao a biological agent uses itself, normally bacteria or enzymes, to degrade toxic composites in the effluent ones. But, the synthetic corantes are not of course biodegradveis, being necessary the creation of crossed ancestries of microorganisms so that if it can biodegradar them, something that, even so demands time and research, comes being obtained successfully.

Although attainment of enzymes presents a cost one in such a way how much raised, its use is of bigger easiness, is used in the treatment and effluent peroxidase, catalase, amylase, lacase and tirosinase as information gotten in download of 20 selected writings OQSP 2007, in 09-10-2010. The two first ones are used, isolated or in set, to decompose hydrogen peroxide (H2O2), in waters of not only reject, as well as after the alvejamento of the fabric, therefore the residual H2O2 can compromise the tingimento. The amylase, in turn, is used in the desengomagem, for the division of the starch in glucose and also in the cleanness of effluent when it has residual starch. Although not to have so expressive paper, aid indirectly in the cleanness of effluent because ' ' substitutos' ' chemistries in the task that exerts (normally acid or bases) are well more pollutant. Already lacase and tirosinase is two removed enzymes of fungos with great utility in the treatment of effluent, even so in different ways. Lacase acts as bacteria above cited, degrading molecules of corante, and, what it is better, obtaining to degrade or the least to facilitate the biodegradao of great part of the synthetic corantes.

PowerPoint

When looking for to describe its current relation with the new technologies, the formandos say if to feel more to the will since they had passed a good time evaluating and perfecting its knowledge in relation the TICs. A mathematics professor must be capable to carry through the proper professional activities of a professor and to personally identify professionally and with the profession and the substance that leciona. This means to assume the point of view of a professor, to interiorizar the respective paper and the natural ways to deal with the professional questions. In the initial formation of professors, the formandos must make contact with applications as the text processing, data-base systems of management, programs of treatment of image, leves of calculation, programs of statistics, programs of presentation as PowerPoint, post office electronic, as well as guided educative software for the learning of you discipline you specify, as well as the Internet, as much in the source of consultation as in the production source. Carried through studies of inquiry in diverse countries show that the TICs can, in the reality, to play an important role in the initial formation of professors. The potentialities of the TICs cause changes in the paper of the professor, to supply information start to create learning situations, the paper to control starts to be to defy and to support; the paper of uniformizar starts to be the paper to diversify. It is responsibility of the professors to observe the learning of the formandos with regard to the new technologies? TICs. When pedagogical practical considering one established one in the development of the TICs we are speaking in leaving of side the rigidity of the had contents as universal and starting to work from originated projects of the curiosidades and investigations of the pupils front to the reality in which they are inserted. In this point if it observes the evolution of the pupil in use of computing since, the TICs had also invaded the educational scope, and through them the individuals have greater access the data and information never seen in other times.

Mother in the Kitchen

Mothering includes many roles suchas caregiver, sympathizer, nurse, psychologist etc. One of mom's roles is in the kitchen, but not just feeding the family. Mothers can have the deepest "casual" conversations while cooking, educating the kids without appearing to educate them. they can cook up good food that will raise their children's spirit or celebrate their triumphs in life.
