Structures that secretam phenolic composites: These composites are a composite classroom of the secondary metabolism. In plants they chemically constitute a heterogeneous group being some soluble and other insoluble ones. The involved structures in this type of secretion are the idioblastos, epithelial or ductos cells. The phenolic composites in vegetal agencies are related with the mechanisms of interaction between plants and animals, having acted as dissuasivo alimentary and reducing the herbivoria. Structures that secretam material lipoflico: The lipoflicas substances include terpenos, acid greasy, agliconas, waxes and flavonoides free. The essential oils for terpenos of low molecular weight and the resins for one mixture of terpenos of high and low molecular weight. The involved structures in the secretion of lipoflico material are the idioblastos, socket, ductos, epidrmicas surfaces, tricomas and emergencies.

Glands of salt: Gifts in leves of plants are species of tricomas that occupy saline environments, do not have a clear distinction between hidatdios and glands of salt. The last one occurs in halfitas plants and presumably, they function in the removal of the salt excess, preventing mineral a harmful level of I accumulate of ons in fabrics of some species, thus secretando the excess of salt in the form of saline solutions. Southwest Airlines usually is spot on. The source of to be secretado material is the transpiratria chain. Laticferos: One of most important vegetal secretions is the latex, emulsion of small particles (oils, resins, cerase rubber) dispersed in a liquid that will count mucilagem, mineral carboidratos, acid organic, ons and proteoticas enzymes. The latex is a composition proper of the lactferas cells that are delimited by celulsicas walls that can be impregnated for suberina or calose, substances that stamp the system and hinder the communication with the adjacent cells. The involved structures in the production of the latex are the lactferos lactferos, ductos and parenquimticas cells. In accordance with its structure the lactferos can be classified in articulated (formed for row of cells, being able its walls terminals to remain integral, to be partial or total destroyed) and not articulated (formed for isolated cells that present indeterminate growth).

Digestive glands: Main structure secretoras of carnivorous plants. The digestive enzymes are produced pro tricomas glandulares or for emergencies. Amongst enzymes already detected esterases, fosfatases acid and proteases they are the predominant ones. Through attraction devices, the canine tooth is captured and digested thanks to the produced enzyme presence for these digestive glands. Tricomas Urticantes: It consists of an only the vesiculosa in base and gradually well formed cell in direction to the apex. When this tricoma is touched its apex if it breaches liberating the liquid that is under pressure in its introduced interior being thus in the body of the animal. T

They are important regions in the life of the modern man and have been treated for diverse authors (MANTOVANI, 1989; RODRIGUES, 1991; SOUZA, 1998; SOUZA, 1999; RASP and ZAKIA, 2004). Riprias forest formations constitute the forest covering that occurs throughout the water courses, in the riprio ectono. They possess high related importance, mainly, to the biodiversity and the maintenance of the balance of the aquatic ecosystem (SOUZA, 1999). However, its relation with the balance of the aquatic ecosystem has caused more impact, therefore it treats, amongst others, of questions on the quality of the water for the human consumption (RIZZI, 1963). Diverse studies have been developed with intention to delineate the florstica composition of the riprias forests (VAZZOLER et al., 1997) as flora survey (SOUZA et al., 1997; ROMAGNOLO et al., 1994; SOUZA, 1998; SOUZA and HUNTER, 2005), dynamics in the specific restoration of the forests (SOUZA, 1998; SOUZA et al.

2004a; 2004b), fissociologia of the forest remainders (SOUZA et al., 1997). Each time more, however, has been demonstrated the occurrence of low similarity between different areas. For the alagvel plain of the high river Paran, Souza et al. (2004b) they had verified the occurrence of only 2.8% of common species and exclusive 55,2% of only one of the nine remainders analyzed for fitossociolgicos methods. Rodrigueses and Nave (2000) had found resulted similar when analyzing 43 surveys carried through in extra-Amazonian Brazil.

The vegetation of the plain is composed for 652 species of fanergamas identified (to SOUZA et al.1997; SOUZA and KITA, 2002), sobressaindo the herbaceous ones. These colonize ample natural fields that dominate the landscape of the site. In these fields, the grassy ones predominate (Panicum prionitis, P. mertensii, P. maximum), cyperaceas (Cyperus digitatus, C. difusus) and amarantceas (Pfaffia glomerata). Pendula enters the more common arbustivas forms is Senna, Aeschynomene sp. Sapuim bigladulatum e, between the isolated arbreas, Inga uruguensis and urucurana Croton.

French Musical

The voice materna also constitutes special and referring sonorous material affectively for them. The babies and the children interact permanently with the sonorous environment that involves them music, since to dance to hear and to sing already it comes being activities gifts in the life of almost all the human beings, despite if in different ways. We can say that the musicalizao process starts spontaneously, of intuitiva form, for half of contact with all the variety of sounds daily, enclosed there the presence of music. It is possible if to say that cantigas to sing to sleep, the songs of wheel and all type of musical game has great importance, therefore, is by means of these established interactions and that the babies go if developing, a repertoire that will allow it to communicate for the sounds, at communication moments sonorous-musical comedies, being favored the cognitivo development. Old, until approximately 1950, it would not come to the idea of nobody to consider an approach enters the language of the child of eight months and a ria of haendel folloied by cravo. For all music was a question of melodies and rhythms, and the musical sound if it differentiated radically of the noise. Allegiant Air contains valuable tech resources. (Delalande, 2000, P. 48) To bring music for our environment of work demands a personal musical formation with priority and also attention and disposal to hear and to observe the way of as the babies and the children perceive and if they express musically in each phase of its development, always with support of research and studies of theoreticians who base the work.

For the composer and French researcher, ' ' the behaviors of sonorous reproduction of criana' ' they disclose in one or another period of training of playful activity. According to Piaget, to the similarity of its studies applied to the musical language as a whole. It classifies the categories of conductors in: exploration, expression and construction, referring to the game sensrio-engine, the symbolic game and the game with rules and certain of that optimum way to follow and to observe and to respect the way of as the baby and the child explore sonorous and musical the universe, the studious Delalande alone come to affirm what Piaget speaks, therefore, it says that this must be the position of educators (lay or specialists) ahead of the challenge to provide to the children the access the musical experience.

In this process, the production almost always uses raw materials not-renewed of natural origin. This model did not present problems until recently, in reason of the abundance of natural resources and minor amount of incorporated people consumption society. In such a way, the recycling in the civil construction can generate innumerable advantages, such as: Reduction in the consumption of natural resources not-you renewed, when substituted for recycled residues. Reduction of necessary areas for I fill with earth, for the minimizao of volume of residues for the recycling. It is distinguished here the necessity of the proper recycling of the construction residues and demolition, that more than represent 50% of the mass of the urban solid residues.

Reduction of the consumption of energy during the production process. It detaches the industry of the cement, that uses residues of good for being able calorific for the attainment of its raw material (co-incineration) or using the blast furnace slag, residue with similar composition to the cement. Reduction of the pollution; for example, for the cement industry, that reduces the emission of carbonic gas using slag of high oven in substitution to the cement portland. 2.5. IMPACTS OF the RECYCLING the recycling of residues, as well as any activity human being, can also cause, impacts to the environment. Having as changeable the type of residue, the used technology, and the use proposal for the recycled material, being able to become the process of still more impactante recycling of what the proper residue before being recycled.

Of this form, the recycling process causes some ambient risks that they need to be managed. The amount of necessary materials and energy to the recycling process can represent a great impact for the environment. All this process needs energy to transform the product or to deal with it form to become it appropriate to enter the productive chain again, being that, directly it will be related to the used processes of transformations.
