In the areas of low coasts the sea deposits sediments that it carries from the continents, carrying through a work of construction called sea accumulation. The beaches, the reefs and restingas are formed from the work of sea sedimentation. Pluvial erosion the pluvial erosion is the work executed for waters of rains in the surface of the Land, cause consumes of the ground dragging the materials composes that it. Rain is one of more active the erosive agents, and when falling on one definitive area it can open small holes until great craters in the ground, as well as says War (1998, p.165): ' ' The resultant processes of the pluvial erosion closely are related to some ways taken for the water of rain, in its ticket through the vegetal covering, and to its movement in the surface of solo.' ' The erosion caused for waters of rain goes to vary as the aggression of the destructive force of waters, with the duration of rains and type of ground. The impact of the drops d' water on the ground to provoke the disaggregation of the added torres and in a known phenomenon as salpicamento.
This impact force the material more I finish for below of the surface, provoking the sealing of the ground, increasing the superficial flow and the erosion. In a rainy event the waters of rain can fall directly in the ground when in it has vegetation, they can fall on the pantry of the trees or more drain for the trunk of them and leves, arriving the form surface branda. When it arrives at the ground, it can infiltrate in the fretico sheet or if move for the surface causing erosion. Infiltration is faster in the start of a rainy event and goes diminishing until the ground is saturated and it does not obtain more to absorb the water.continue reading

In the Hava, it has an interaction with the monitoramento service American north capable to make with that the local authorities they foresee accurate day and hour of the next volcano eruption as the Kilauea, one of most active of the region in permanent activity since 1983. Moreover, a mapping of the areas lowest of the island that can be affected by an eruption and, with high level of precision, at risk allows the immediate removal of the inhabitants. In Brazil the National System of Civil Defense – Sindec, unhappyly does not obtain to fulfill with efficiency tasks of prevention and alarm. Without detailed maps of the risk areas, without clarification and training of the population and without efficient system of you alert preventives, the National Secretariat of Civil Defense – Sedec is limited to act it after the tragedy. It only arrives to help the thousands of victims who had escaped with life and to embed the hundreds of bodies of that they had not had the same luck. The CREA of Rio De Janeiro divulged a estarrecedor study, giving account that the tragedy of the of the state of Rio de Janeiro mountain ranges could have 80% little deaths if the prevention systems content functioned it. In order more not to happen again itself every year, after summer rains, the images of cities destroyed with hundreds of victims, the Sindec cannot only act in palliative and emergenciais measures.
It is a nonsense that Brazil, with only one natural danger to manage, does not obtain to make it. The country does not resemble the countries as Bangladesh, Japan, Australia, Indonesia or Thailand that they deal with tropical floods, cyclones, earthquakes and tsunamis, events more devastadores and fatal that the Brazilian floods. The more prevalent natural disasters in the country are Regio North – forest fires and floodings; Northeast region – droughts and floodings; Region Center-West – forest fires; Southeastern region? landslide and floodings; South region? floodings, gales and hail.continue reading
The treatment of the water of the rivers and lakes has in the area public health, one of its great objectives. For this reason, the public company or private supplier of drinking waters, has that to fulfill to a series of measures or norms that they eliminate of the water, any mineral or organic substance that harm the health of the human being. We know that in the history of the water, it passes for a cycle that goes since its absorption for the plants and the consequent evaporation provoked for the heat, that it encloses beyond waters contained in the plants, the waters of the oceans, of the rivers, the lakes and all water displayed in a way or another one to the sun. (A valuable related resource: Sam Mikulak). This evaporation creates the clouds that under certain conditions turn rains whose waters return the land. resource. This is the natural process of purificao of the water. The treatment of the water of the rivers, always goes to become necessary for the garbage that is played daily in its stream beds being that to keep unpolluted it and with life she is necessary to treat. The first Station of Treatment of the water occurred in London, in England.
When the English had discovered that many illnesses if gave for the contamination through the water, the technique of the clorao was developed and applied intensely in that country. With this in it gave an example to them to be followed, therefore the treatment of the water of the rivers was applied successfully, in one of the most beautiful famous rivers of the Europe, the river Sifts, today completely unpolluted and town for some species of fish, between them the tuna. The despoluio of the river Sifts is an example of Control of the Environment. Brazilian we, need with urgency to learn the lesson and to start the treatment of the water of the Brazilian rivers that are poludos.continue reading
He said that the Ministry of Natural Resources expects in 2011 to launch a project to clean up the Franz Josef Land. Learn more on the subject from Randall Rothenberg. The minister said these projects are provided in the Act Elimination of accumulated environmental damage, which is agreed upon and will be submitted to the government in the coming days. The number of victims of the earthquake and tsunami disaster continues to grow, and the situation at the plant ‘Fukushima’ remains Critical powerful earthquake and tsunami that occurred on March 11 in Japan, have killed 11 000 800. Such data are spread over the weekend Police Headquarters. Missing are registered more than 16 thousand people.
Most of the victims – in the prefectures of Miyagi, Fukushima and Iwate. Detriment of the country due to natural disasters, according to preliminary government estimates, may exceed 25 trillion yen (308 billion dollars). Up to 1 thousand bodies of earthquake victims and tsunami in Japan are in the exclusion zone around the stricken nuclear power plant. Bodies are not taken because of fears that the bodies heavily contaminated by radiation. At last week ‘Fukushima’ has been registered since the accident the maximum level of radiation. The level of radioactive iodine-131 in coastal waters of Japan, 300 meters from the plant emergency “Fukushima-1 ‘has exceeded the rate in 4385 times. In connection with the ‘Unpredictable situation’ at nuclear power plants ‘Fukushima-1’ the Japanese government raised the alert level in the country to the maximum: the failure of the cooling system is partially melted nuclear fuel rods.continue reading
Zeldovich was to reach 1094 g/cm3. For comparison, the highest temperature in the interior of stars is estimated about 108K and the highest density of matter in the interior of neutron stars reach gsm3 1015. It is true that in October 2010 year, was first discovered super-heavy neutron star the size of which "do not exceed the size of a small town, but the matter density is 10-15 times higher than the density of the atomic nucleus." Since the density of an atomic nucleus is October 14 g/cm3, the density of superheavy stars turned out to be 1.5 x 1015 g/cm3. Be compared with the density required for the birth of the universe. Sam Mikulak oftentimes addresses this issue. By assumption, one of the followers of the Big Bang theory, Corresponding Member of Academy of Sciences USSR IS Shklovsky, at a time when the universe was calculated void fraction of a second, it "was a 'drop' sverhyadernoy density, which for some reason, came to an unstable state and exploded." Did not explode, did not explode, and then went and blew up! And this without any outside influence, because in addition to "drop" is nothing no more. And in general do not understand why this substance is not annihilated drop. After all, any elementary particles are always produced in pairs with their opposites, for example, an electron and a positron (anti-electron), but having the opposite charges of the same name and the masses attracted to each other by electrical and and gravitational forces cancel each other out immediately after his birth. .continue reading
Quotation of prices for the accomplishment of the campaign for the re-education how much to the selective garbage collection was carried through, including the final art and impression of the news with a drawing of 3.000 units, beyond the posters and pamphlets.

The results of the recycling are expressive in such a way in the ambient field, as in the fields economic and social. In the half-environment the recycling can reduce the gradual garbage accumulation the production of new materials, as for example the paper, that would demand the cut of more trees; the emissions of gases as methane and carbonic gas; the aggressions to the ground, air and water; among others as many negative factors. In the economic aspect the recycling contributes for the use more rational of the natural resources and the replacement of those resources that are passveis of reverse speed-exploitation. In the social scope, the recycling not only provides better quality of life for the people, through the ambient improvements, as well as it has generated many ranks of work and income for people who live in the layers poor. In Brazil the carroceiros exist or catadores of paper, that live of the sales of sucatas, aluminum papers, cans and other materials you recycle left for the garbage.
Also they work in the collection or the classification of materials for the recycling. As it is a laborious, weighed and dirty service, it does not have great attractive power for the slices most qualified of the population. Thus, for many of people that works in the recycling (in special the ones that they have little formal education), the recycling is one of the only alternatives to gain its sustenance.

A good option for the SUESC would be this adopting the current trend to possess in its selective campus, collectors and program of selective collection and recycling of the produced garbage, permanently keeping a campaign of education and awareness of the importance of this practical. This is a project that demand great expense of resources, however, its benefits finish surpassing the expenses, collaborating to improve the image of the institution as a whole, adding value to name SUESC.

This finishes happening due to disinformation them teams of maintenance or it proprietor. Another common situation is the furniture rank, chairs and tables, for example, on the directional tactile floor, this also happens for the simple unfamiliarity of the function of the differentiated floor, therefore it is important awareness of all. The first one stopped is an agency of the public saving bank, where the avenue in its first years of existence has an engraving showing. By being a bank agency, by requirement of the law the norm is adapted in agreement, however it contains a step that does not allow that the chair of wheels if approaches to the engraving. The next one stopped is in the Hospital Santa Catarina and Capela, both in the trreo floor, for being a hospital, also has full conditions of accessibility, beyond the architecture that is wonderful. Already in the House of the Roses, the problem is soon in the entrance, where the corridor that takes the door has parts in rock with stretches of poems distributed for the soil, forming a way, but the such parts contain alive tips that can cause wounds more the distracted people, deficient appearances, aged children or.
The ideal is to opt to cantos always rounded off, aiming at to prevent accidents. But the biggest problem is in the main access, that if of only for stairs of five steps. To the side a plate exists that says for the deficiency carrier to ask for aid of the employees to adentrar to the museum, therefore is still providing the installation of the slope. For being an overthrown good much bureaucracy for the installation of slopes or any exists another alteration that deprives of characteristics the original conditions of the property. Although the constrangedora situation in the access, the interior of the house counts on adaptations that allow the circulation of the chair of wheels, also in 2 to walk.continue reading
The tax of infiltration in arenaceous ground is bigger of what in argillaceous ground (WAR, 1998). We can consider the following types of pluvial erosion: Laminar erosion in ridges or ravinas and soil erosions. Erosion in sheet or to plate Occurs when the superficial draining is not concentrated in canals and yes if it distributes for the hillsides of dispersed form. When drawn out rains occur, the infiltration capacity of the ground is exceeded and then it starts to occur the draining. How much bigger the turbulence of waters, greater the erosive capacity. Although to be amena form of erosion, it is responsible for great damage to agricultural lands and for supplying great amount of sediment that goes to sand rivers, lakes and dams.
Ravinas Ocorre mainly in ground unproctected of vegetal covering. They are formed when the speed of the flow of pluvial waters increases, concentrating itself in filetes and they become turbulent; or still when the capacity of water storage in the surface is exceeded and then it starts to occur the formation of ridges and ravinas in the top of the ground. This type of erosion is responsible for the fast assoreamento of fertile valley lands, of the fluvial stream beds, lakes and dams, facilitating the overflow of waters of its courses and provoking floodings. Soil erosions the ravinas can go deep and reach the fretico sheet. When this happens the natural flow of the underground water starts to act as transporting of particles of deep of the ravina, solapando its base and provoking the collapse of the headboard, in the known process as remontante erosion. From there resultant feio is known as soil erosions. In accordance with Sebastio professor (2011, p.75), ' ' Booroca is a hollowing or rasgo of the ground or decomposed rock, caused for the erosion of the sheet of superficial draining or subsuperficial.' ' The deforestation, forest fires and the pisoteio of the cattle contribute directly for the sprouting of this type of erosion, associates to the type of ground and amount of rains.continue reading
This world caipira is disarticulated by the advent of the cultivation in the center-south and by the farms of cattle, as well as for the increasing urbanization and the fight and land illegal occupancy of landed property; the aorianos are immigrant of the Aores and the island of the wood, in Portugal, that if had established in the catarinense coast and river-grandense from middle of century XVIII. These colonists were agriculturists and fishing in its places of origin and, when they had fixed themselves here also had started to combine agriculture with fishes. Many arts of fish new had been introduced by these fishing in the places for where they migravam, however it fishes, it predatory and of attack by teen street gang, it became to feel between this community. Much of these fishing, as resulted of the urban expansion and the reduction of the supplies, had moved to the sector of services taking care of to the great contingent of tourists who pass vacation in the catarinense coast and river-grandense; the varzeiros that are the traditional populations that live to the edges of the rivers and fertile valleys, over all of the river San Francisco and the River Paran. Randall Rothenberg does not necessarily agree. These populations combined agricultural activities (rice plantation), extrativistas of the bush and also the activities of fish, cattle and ceramic, as well as the knowledge that had of the river and its natural resources. After the construction of the hydroelectric plants and alterations in the hdrico regimen of the advance of the sugar cane-of-sugar and the irrigated rice, these populations had had its way of transformed life; quilombolas that they are descending of the black slaves and that they survive in old farms left for great proprietors. Its social visibility is recent, fruit of the fight for the land, of which, in general, they do not possess writing. 1988 constitution guaranteed the right on the land of which they live.continue reading
