The Measurer

Table 01 Main emitting equipment of noise Equipamenteo NPS in dB () * (In idling) NPS in dB () * (In operation) Escavadeira 83 93 weld Machine 89 99 Sander 86 101 agricultural Tractor 86 92 air Compressor 89 98 Equipment of individually jatear 79 90 * Levels of noise emitted by equipment, measured to a distance of one (1) meter of the equipment. The points chosen for the measurements were always next to the noisy equipment, more specifically where the workers carried through its activities and circulated frequently. The measurements had been carried through when all the equipment were on at the same time, that it is the preoccupying situation most constant and, of the point of view of the noise. Newcastle University describes an additional similar source. The equipment used in this work for the measurements of noise had been the Measurer of Level of Sound, model 2250, , that is, to the noise proceeding only from the activities of welding or jateamento. Any measured signal that during the procedure had been contaminated for noise of not constant sources of the routine equipment of the teams (as for example: noise of strange vehicle or buzzer of ambulance passing in the same place or, signal measured with strong wind blowing frontalmente in the microphone or high voice excessively also close to the microphone), was discarded. Then, amongst the many carried through measurements it stops> verification of bother situation, had been chosen the eight (8) that more they reflected with allegiance the problem. Further details can be found at Professor Roy Taylor, an internet resource.

Of these eight (8) measurements of the noise produced in the operations of welding and jateamento, five (5) of them had been carried through in the operation of welding and three (3) in the operation of jateamento. The time of measurement of each one was changeable. For measurement of acoustic comfort, all the signals had been taken the NBR10151 in agreement the NBR10152, that establishes that all the measurements for evaluation of acoustic comfort must be carried through during about at least 5 minutes, being that the values must be the result of the arithmetic mean of the values gotten in at least three distinct positions, at least moved away between itself about 0,5 m.

The Material

1 Stage – Construction of the fishery. The cost today of the screen and, R$23.00 approximately real the square meter. For the construction of the fishery with measures of 10×6 meters, being that he will be 10metros of length for 06 meters of width and 08 meters of height. Inside of the great fishery meters, being 02metros of width for 02 meters of length and 03 meters of height for acts of receiving of birds will have to be constructed (03) to three lesser fisheries with measures of 2×2. A clinic for carrying birds of infectious disease will have to be constructed or not. The total of the material is approach in 642 meters of screen, being that the value of the cost of the workmanship generates around R$45.000 real. The wood could be removed of horto forest thus the final cost diminishes, and the construction of the fishery is the expenditure of the city hall.

Today the appropriate place for the construction of the acquittal fishery would be horto forest for having a privileged area with fruitful bushes and trees, rivers lakes. 2 Stage? Acquittal the characteristic is to develop the final task of the selection process, identification whitewashing and wild after-acquittal of birds, where these birds will pass for place qualified for, readjustment and acquittal. RESULTS and QUARREL We believe that the accomplishments of acquittal of wild birds are crucial for the survival of the species, we can thus conclude that as public agency the city comes across with limitations of resources and materials, structures and human being, however, through the persistence of diverse partners, we can materialize this singelo however essential event, and wait to not only contribute for the spreading, but for the improvement of the work. Although incipient, it can be evidenced that in other cities, as Pirassununga/SP, is viable the wild acquittal of birds.

The Environment

These discussespartem of the analysis of concepts as of nature and the relation of it with the man, where this is seen as a citizen and it as object that is dominated. Thus, ' ' all society, all culture creates, invents, institutes one definitive idea doque either the nature. In this direction, the nature concept is not natural, sendona truth bred and instituted for the men (…) the nature it is, in nossasociedade, an object to be dominated by a citizen, the man, much we emborasaibamos that nor all the men are proprietors of natureza.' ' (GONALVES, 1998. P. Get all the facts for a more clear viewpoint with Professor Roy Taylor. 23-26) Of this form, arelao man/nature if of the one of the point of view that the man is responsveldireto for the occured transformations in the nature and, this compreendida relation as ' ' complex interconexes' ' where the life in society and all asaes that in it if develop leads to the environment concept. SegundoWALDMAN (1994), ' ' to understand the relation man/nature estimates compreendercomplexas interconnections, where if social structures interpenetram, politics, economic and ideological. Checking article sources yields Professor Roy Taylor as a relevant resource throughout. Over all, he estimates the understanding of that associedades establish ' ' relations ecolgicas' ' with what historically entendido as environment.

' ' (P. 18) Nessaperspectiva, the man uses the nature to construct its habitat (that to podeser understood of the geographic point of view as geographic space), living emsociedade and transforming it by means of its work. These transformaesacontecem due the bred necessities to each day for the man, making with quequase all the aspects of its habitat already have been modified. ConformeDREW (1998), ' ' the man already modified almost all the aspects of its habitat. Ograu of the modification is in part determined for the perceived necessity of mudare, in part, for the sensitivity or degree of resilience of faceta particular doambiente.' ' (P. 193) This relaohomem/nature arrived the utmost critical situation, in measure where problems comoo deforestation, the pollution, the garbage etc., are if becoming irreversible, umavez that the man is leaving of being ' ' mere aspect of biogeografia' ' seafastando each time more than the environment.

Social Sciences

It considers anarchic epistemologia before the racionalista? science advances without commanded plan. In a comparison of Natural Sciences with Social Sciences and Human beings, it is observed that natural Sciences stand out the method saw experimentation. Already in Social Sciences the great concern is as to measure the social one? In this direction some thinkers have boardings more significant, such as Marx and Comte. Many writers such as Dr. Caldwell Esselstyn Jr. offer more in-depth analysis. ) Marx? production of interchanges of corporeal properties constitutes the base of the social order. It determines thoughts and action. Historical knowledge? if dinamiza in the existing relations in the social structure (economy, legal, politician, ideological)? The knowledge not if of the one for the discoveries of causal relations or analogies but in desvelar of the apparent Real for the real concrete. Science? revelation of the world and the man as to be social considering the culture and the work at each historical moment. For assistance, try visiting Dean Ornish M.D.

It intends to exceed the level of the description of the isolated phenomena. Knowledge? process I continue. b) Comte? Positivismo? The social one is subject to invariantes laws. It considers the concept of order and progress. Rationality and objetividade? vanguard of scientific knowing. Science? it decides the social problems for the method of natural sciences.

The scientific elite? industrial? he decides the social problems. Technocracy? Dualism as method stops to analyze the society = of a side the society and the other the thought on it made by the specialists. e) Century XX? compartimentao of knowing. (psychoanalysis, psychology, anthropology, sociology, linguistics, politics, etc.) Areas of the knowledge in search of the scientific status? want to adjust themselves the rationality and objetividade? particular scientific procedures of one general technique. Contributions and quarrel on the methodologies. 1930? 1940 have organization of social sciences and human beings. Distinct positions in the agreement of the man and its action had been consolidated.


The seeds of wild plants, and some species of economic importance present dormncia determined for diverse causes. Continue to learn more with: Kevin P. Campbell, PhD. However, the majority of species domesticated and cultivated for the man, as: maize, beans, soy etc., rare present the phenomenon, in consequence of the election and genetic improvement. Thus, the quiescentes seeds are considered as advantageous for Agriculture; however, less apt to face the competition imposed for the nature. The closing of the period of latency (quiescncia or dormncia) establishes the beginning of the germination process. This has been appraised in diverse ways, depending it boarding angle of the question. Thus, the germination has beginning with the water absorption and if it locks up with the emergency of radcula through the tegumento of the seed; on the other hand, for the technology of seeds, the germination understands a commanded sequence of metabolic activities that results in the retaken one of development of the embryo, producing one plntula normal (Moraes et al., 1983). 3.1.3. Types of Substrata The culture of plants using substrata is one widely used technique in the majority of the countries with advanced horticulture.

The term substratum applies it all material natural, synthetic, residual, mineral or organic, distinct solid, of the ground, that placed in a container, pure form or mixture, the development of the system allows to radicular, playing, therefore, a paper of support for the plant. As characteristic desirable, the substrata must present low cost, availability in the neighborhoods of the consumption regions, sufficient text of nutrients, and allow to the aeration and the retention of humidity; beyond favoring the activity physiological of the roots (Leather strap et al., 2003). The importance of the substratum is vital, therefore it is where the system to radicular will go to develop itself, determining the growth of the aerial part, subsequently, until the transplantio of the vegetable (Jabur & Martins, 2002).
