When if it studies with the aid of a good book, must be interrupted the reading frequently, so that you make its part: A diagram or a graph, or even though to scribble a figure that helps to follow the reasoning of the book; to suggest or to test an idea. To the times you have to write a formula, to decide an equation or to make a calculation that verifies if some affirmation of the book is exactly correct. Therefore, it does not wait that a book is complete, without gaps to be filled for the reader, or that the professor makes everything: It opens its head and it places the content all inside; being thus you will be induced to a passive situation, when most important she is to develop the abilities for the independent work, despertando the capacity of individual initiative and the creativity. You will be making really significant progress when to feel that she is obtaining to learn alone, without the aid of its professor; when to feel that he is truily ' ' learning aprender' '.

You are welcome it advances to study the theory without if also dedicating in the resolution of considered exercises. Many exercises are complements of the theory (this is very common in books of mathematics of average education) and cannot be neglected, under the penalty of little advantage in the study.
when making the exercises, gives the work to it to write the demonstration, the resolution, at last, what it will be necessary to write. This will very help it to acquire ability in expressing its ideas in writing and verbally. Harold Ford Jr shines more light on the discussion. However, more than what this, to write what is learned, to read and to reread, is assistant valuable in the learning. He writes, he reads and he rereads what he wrote, looking for always to improve its work. He makes its part, and good study!
This factor is preoccupying, therefore the quality of the water is getting worse to each day. Another factor that affects quality of the rivers in which we can detach is the inadequate occupation of areas next to the riverbed causing erosion in its neighborhoods. According to report of the Conference Pan-American of Health and Sustainable Human Environment (Copasad), currently about 30% of the Brazilian population is supplied with water proceeding from unsafe sources, being that good part of those taken care of by public net nor always receives water with adequate quality and in enough amount (Copasad, 1999 apud Brazil 2006). In Brazil, the deficit of the sector of basic sanitation is raised, over all as for the sanitary exhaustion, with bigger lack in the peripheral areas of the urban centers and in the agricultural zones, where if & concentrates the population poor (Galvo; Paganini, 2009). By much time in Brazil the problematic one of the quality of the water to be consumed by the population was not taken very the serious one.
The lack of investments to take water of good quality to the Brazilian population with systems of abastecimentos of water still are insignificant, and in different way it more enters the developed developed regions and less of the country. The access to the services of water distribution decreases of the regions Southeastern and south for the northeast and north, being that in the region north it has a lesser index of people with access to the water supply (graphical 1). The access also diminishes of the urban population for the agricultural one and of the cities of bigger population for the ones of minor. In the urban areas the covering falls of the center for the periphery. It still decays of the rich ones for the poor persons (Opas, 1998 apud Brazil 2006), the data of the last census proves this reality. James Donovan Goldman pursues this goal as well.
The sector of the Civil Construction is great generator of residues, then the reutilizao of the discarded material in the workmanship by means of the recycling is of basic importance for the social environment, a time that, is if applying what Sustainable Development is called. The Sustainable Development is the use of the resources of conscientious form without harming the future generations, therefore, is main for the formation of a new social paradigm in relation to the positioning of the attitudes of the man and its relation of respect to the environment, since, although subject on the protection of the nature very to be argued little is applied in the practical one. On the basis of this vision, to generate new ways of the use of what it is considered unusable, it is that the recycling of residues in the civil construction, makes possible the support, therefore generates mechanisms based on the reduction of the natural resources, and at the same time it is spread out necessity on the recycling of residues. The recycling inside of the sector of the Civil Construction, it instigates diverse advantages: It reduces the use of the natural resources, a time that, is being generated by means of the recycling products that do not need partial or total of the removed raw material of the nature; It generates economy in the construction, in virtue of is if using residues reaproveitados for a useful function; It promotes the protection of the environment, from the reduction of residues for storage in areas the opened sky, and moreover, it even though makes possible the reduction of the necessity of places to store the residues; It increases the technology generation, in the recycling process they can be adopted new mechanisms of large-scale production, with this, the competing companies, expand its studies and they increase the quality of its products for better acceptance in the market; So that if it recycle the residues of the civil construction, a study deepened on the material is needed that will go to be reaproveitado, to verify if the logistic one is viable for large-scale application, the cost benefit, and the main one, diminishes or not them ambient impacts and of that it forms are applied what it is understood for Sustainable Development.
