Soil Erosions

Carlos Antunes de Freitas Jnior 1? after-graduating ISEIB? Management in Environment, tecnocarlos7@ yahoo.com.br Summary – Processes the urban ones of general form are enterprises that cause changes the landscape, relief, ground, water, fauna and flora. The growth disordered planning or of the cities can lead has ambient and human damages. The lack of urban planning for draining of pluvial ones, and the relation of rains and torrents canalized for the streets and side streets of the high quarters in the Buritizeiro city, had caused the formation of soil erosions in the quarter garden of the Buritis, these had evolved and arrived at the fretico sheet forming new springs due to the local characteristics of area of springs and trails. Additional information at Ebay supports this article. The erosive processes in the interior of the quarter Garden of the Buritis already are seen as a normal process in which the public managers make workmanships of improvement for a convivncia with the erosive processes as canalization and bridges. Words keys: Garden of the Buritis, urbanization and soil erosions. Abstrat – The you process ploughs generally urban developments that causes changes you the landscape, topography, soil, to water, fauna and flora. The growth of huge cities or planning can take in the environmental damage and human.

The lack of urban planning will be the disposal of to rainwater, and the relationship of rainfall and runoff channeled through the streets and alleys of the neighborhoods in the City Buritizeiro high, caused the formation of gullies in the district of Buritis garden, they have evolved and cam you forming new to groundwater sources due you the place-area springs and trails. The erosion in the middle of the neighborhood of Garden Buritis ploughs already viewed the normal a process in which managers make public works of improvement will be living with the erosion and pipe bridges. Key Words: garden of the Buritis, urbanization, soil erosions.

Biological Sciences

Two teros of the Planet Land are constituted of water and Brazil is an immense reservoir, has 12% of all the water available candy in the world. This represents 53% of the water of Latin America. Each Brazilian makes use of 34 million liters per year, a fantastic volume, therefore according to ONU (Organization of United Nations) is necessary two million liters of water per year, for a healthful life. But unhappyly the water badly is distributed, 80% meets in the Amaznia, where only 5% of the population live. 95% of the Brazilians is with 20%, therefore much people suffer with the scarcity of the water. She has much wastefulness, being that of 100 liters of proper water for consumption, 60 are only used to advantage.

They esteem themselves that 30% if lose in emptyings for the streets. Bad habits (open taps or dripping, long banns, deficient sanitary discharges, etc) contribute for wastefulness. Without speaking in the problems that we have with the quality and exploitation of the water due to basic sanitation and cares in the management of the garbage. Being that the water is important for all the beings livings creature, also animal and plants. About 75% of the human body he is composed for water. Moreover, many activities human beings as feeding, hygiene, transport, leisure, industrial, commercial and agricultural processes demand of water in adequate quality and amount. Our threatened and compromised superficial waters are each day more and will continue threatened if not to modify our attitudes. Therefore he is imprescindvelque the people take care of of the environment, playing the garbage in the garbage, to prevent the contamination of the water and to follow the example of the dolphin, that she looks to keep clean the water where she lives, removing strange objects, garbage and all the impurities that can poluir the territory where it lives. Not to take care of of the water means to place all at risk the life that exists on the Land.

The Membrane

To get rid of most harmful bacteria, it takes a few seconds. And at an extremely low operational costs ultraviolet can handle thousands, tens and hundreds of thousands of gallons of water. By the way, thanks to this safe method of cleaning the inhabitants of St. Petersburg has been enjoying since 2007, unlike other Russians drinking water. But here, do not relax. Once the water enters the water supply network, there are big water adventure. Through the old, sometimes rotten to the water pipe will be exposed to hazardous substances bacteria and viruses. Suffice it to recall, when an accident occurs or replacement of water pipes – the water from the tap for an hour passes smoothly from dark brown or black to transparent.

And that got into the pipe at their welding – no one knows. So anyway, tap water can not drink. And then the question arises of its purification and drinking water quality is entirely dependent on our choice. And that today the market offers for domestic use? At present, widely used various filters – Membrane and a coal-based. As a rule, they only clean water from chemical and mechanical contaminants.

Membrane filters. Membrane processes can be classified by size of delayed particles into the following types: microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse osmosis (RO). In going from microfiltration to reverse osmosis membrane pore size decreases and, consequently, the minimum amount of delayed particles. In this case, the smaller the membrane pore size, the more resistance it provides to the flow and the greater the pressure required for the filtering process.

This procedure not only must be carried through inside of the pharmaceutical attendance in the EAS, as well as in pharmacies and would drug commercial. The manuscript of this residue must take care of to the norms of occupational prevention for manuscript of chemical products. The vaccine discarding must exactly take in account the microbiana nature that inactivated of the classified residue being as group residue. the ACCIDENTS WITH PERFURO-CORTANTES Although the measures of security, accidents involving material biological they are frequent between professionals of the area of the health. Some patgenos exist that can be transmitted by material exposition involving biological, especially blood.

The told viruses more in these accidents are the virus of the imunodeficincia human being (HIV), of the B hepatitis (HBV) and of the C hepatitis (HCV). The average risk of if acquiring HIV are of approximately 0.3% after perforate-cutting accident with contaminated material, and of 0,09% after mucosa exposition. They exist, in the world, 100 cases more than confirmed of occupational transmission of the HIV in professionals of the area of the health. How much to hepatitis B, the infection risk can after be superior 30% perforate-cutting accident, case the patient-source is carrying of the virus. In relation to hepatitis C, the average risk of acquisition is of 1,8% (varying of 0 7%) after contaminated exposition with perforate-cutting. The unsafe act and the inadequate manuscript of this group of residues make with that the accidents are more frequent not only for the workers of the group of nursing as well as for the activities of hygienic cleaning of clothes and utensils, activities of nutrition, hygienic cleaning of the sectors, etc MANUALS AND CARTILHAS OF PROCEDURES the NR the 32 and PGRSS have the same lines of direction how much to the creation of Manuais and Cartilhas de Procedimentos.

Coastal Region Of The Amap

The coastal region of the State of the Amap approximately possesss a linear extension of 650 km and a 67.518 area of km2, defined on the basis of the geographic area of the cities. Thus, according to PNGP National Plan of Coastal Management, the coastal region of the Amap, presents following the two setorizaes: The first call of Atlantic or oceanic coastal sector – coastal space correspondent above of the River Araguari, enclosing the cities of Tartarugalzinho, Pracuuba, Amap, Caloene and Oiapoque. This sector corresponds the 450 km of extension and 57,001 km2 of area, representing 40% of amapaense total surface and 84% of the coastal zone. It shelters less than 10% of the population of the State, with a demographic density sediments amount of and water are related with the estuarino system of the River Amazon, responsible for the launching to the sea of enormous candy, that is dragged by chains, having gone to deposit throughout the coast, being formed extensive mud plain. Had the intense action of the tides and chains d’ water in this region occurs the modelao of the coast of the Amap, configuring spaces characterized for the predominance of the performance of erosive processes and another phenomena where if they strict observe bands of addition of materials (Handle Cassipor and Cabo Orange). Studies developed for the Federal University of Par, in the coast of the Amap, have demonstrated and quantified the hydrodynamic conditioning in the formation of the coastal space of this region. By the way of the ocorrentes manguezais throughout the Atlantic coastal sector, whose composition truily denotes the degree of influence of the estuary of the River Amazon, it makes an impression for the extension of its forests, being estruturamente well formed, with average height between 20 meters and 30 meters, distinguishing itself three predominant florsticos types: the 1 – siriubal, environment dominated for siriba (Avicenia germinans, Jacq.); – the mangal, environment dominated for red fen (2 Rhizophora spp.) and 3 – the tintal, environment dominated for the tinteira (racemosa Laguncularia Gaertn.) In such a way, these characteristics, characterize the coastal region of the Amap as of great importance for biological productivity, mainly how much to the supplies of fish, shrimp and crustaceans.
