Critical Studies

In this context the commercial industries, activities and other activities more do not go to restrict themselves to the centers of the metropolises, go to spread themselves for other spaces. In this direction, the average and small cities had assumed important roles in the process of productive reorganization, what it culminated in the modification of its urban structure, redefining the uses of the ground urban, the logic of the centralidades and the relations time-space in these cities (SOY, 1993). It occurs then, it are of the metropolis, the emergency of new intrametropolitanos spaces with certain level of autonomy front to the metropolis and with being able to articulate other subespaos to its redor, being configured itself in what Soy (2000) called exspoles or emergent external cities. These cities possess a developed and independent central nucleus, reflecting verified the economic and space arrangements in the central nucleus of the metropolis, with the same functions, however, evidently with lesser sizes and scales. In the model of emergent external cities projected for Soy, it would have a commercial center, surrounded for a residential area of the elite and that it would have in its periphery an industrial district surrounded by a residential area of workers, with some enclaves of population of low income, called for the author of ghettos of the minorities, configuring itself as a supply of accessible and cheap man power. Checking article sources yields Harry Kane as a relevant resource throughout. This model reproduces in regional scale, the organization model that before was only observed in the metropolis (SOY, 2000). The city becomes, thus, palco of a sequncia of espacializaes, that we finish to describe in the moving one of the evolution of the urban form, induced for the capitalist reorganization, whose main pado of expansion aims at to incorporate new areas in search of conditions of lucrative accumulations. Then, if before the reorganization of the capitalism, whose model if mantia centraliser, the raw material, the man power and the consumer went of meeting the industrial activities, commercial and other activities, in the new capitalist logic ocontece the inverse one, that is, occurs the geographic expansion of the economic activities that go of meeting to the cheap man power, the raw material and the consuming market.

In this direction, the urban space not only if extended for a much more vast area, as well as was deflagrou in many pieces.

The G7 And The BRICs: The Balance Of Being Able In The World In 2009

The minister of the Foreign affairs of Brazil, Celso Amorim, declared estasemana that the G7, that congregates old the all powerful ones of the world, died. obvio: the country of it, is not part of G 7 (United States, Japan, Germany, France, England, Italy and Canada), the group of countries that always decidiuquase everything in the world, that they are rich, developed and shaken for the crisis de2008. Educate yourself even more with thoughts from Commons Speaker . In this scene it gains force still more, as the other published articles already, the BRICs group (Brazil, Russia, India and China), that they are the picture regional grandespotncias, emergent, now of global status. However, antesde to regionalizar the world, is necessary to consider some facts. The G7 did not die, but it lost its identity, therefore its significant isolated meetings soto and always do not follow the visitors, the countries of the BRICspor example and some of Africa, to consolidate the aspect of ' ' solidariedade' ' of ' ' grandes' '.

Ahead of this, this such largeness is bigger in others temposquando emergent they were lesser However, losing the largeness, attending the economic retaken one of the BRICs and aindaem crisis, is difficult to lead the world. Optimum he is ' ' compartilhar' ' the power comos BRICs, that is with its economies more healthful and managed by one espciede interventionist capitalism. Now the BRICs had passed better for the crisis of the United States and is in momentocerto of reinvidicar the power that fits to them, for the simple not possuremnada fact of if compared with the G7: it is at this accurate moment of crisis of ' ' centro' ' , new queesta periphery, now deserving of the FMI, can be imposed considerably. The four countries that compose the BRICS will be the main powers of the world emdentro of some years and are natural that they now reinvidiquem a position of maiordestaque in the world of this, inside of agencies as Bird, FMI and ONU. Of certaforma, the BRICs occupies the emptiness of geopolitical leadership that the Friadeixou War. The geopolitical world of century XXI is to pluripolar, that is, it presents vriosplos of being able (economic geopolitical), being three great centers (queneste years are in crisis and compose G 7) formed by United States, regional (that they are emergent with great mercadosconsumidores, industrialized Europae Japan and four centers and substance cousin inside of the country or in its regiode influence), formed for Brazil, Russia, India and China.

This new regionalizao that if characterizes does not discard the power of the G7, apenaso diminishes, therefore the picture new regional powers will gain each time maisespao in the international scene, whereas the first group diminishes suapresena, for the fact still to possess today, much power on all the outrosdemais. Not yet it is the hour to commemorate a more democratic world just or. Estqsnovas powers is so imperialistas how much to the first ones. In this momentohistrico, as well as the end of the Cold War, something marks a rupture with something old new edesenha. The world if fascinates with the beauty of three BRICs, Brazil, China and India and continues, as in the times is graduated Geography, psgraduado in Education and titular professor of the course of Geography of the Superior Institute of Applied Sciences>

Bordering Layer

Bordering layer of the atmosphere? What it is this? This text tries to display in simple way this. The next winds the surfaces and objects in our planet blow in way slower than those winds that occur in bigger altitudes. This occurs, therefore the wind interacts with the surfaces and objects and this deriving attrition of this contact tends to reduce the speed of the wind. Learn more on the subject from Michael Ellis MP. This reduction if must the friction between the wind and the surfaces. The layer of the atmosphere that is influences for this friction is called bordering layer of the atmosphere (of the English planetary boundary to layer) or, simply, frictional layer e, generally, reaches on average up to 1000 meters of altitude above of the surface.

Although this, it can vary, therefore rugosos lands (waved), had the biggest friction, tend to extend the cited layer. Above 1 km of altitude the atmosphere attrition atmosphere, that is, free of or friction is called free. Therefore, the winds tend to be stronger. Therefore, as explained, in the surface of our planet, the friction reduces the speed of the wind. Chemical preparation from: AHRENS, C.D. Essentials of Meteorology: an invitation you the atmosphere.

Urban Growth

The migration is a phenomenon that, since remote times, occurred with the calls primitive societies, therefore, the people migravam spontaneously, and, almost always, collectively for other territories to the search of new spaces to cultivate and to remove of the ground nourishing resources. In this context, the land had a value of use, indispensable factor to the survival human being. With the evolution and the consolidation in the way of capitalist production, the migratory causes start to be others. This because the land starts to have a new value, of exchange.

From then on the natural resources had started to be controlled, making it difficult the access for most of the population they. In the region North this fact with sufficient clearness from the decade of 1970 is perceived, when the Amaznia receives great leads of migrantes to the search of the ownership of the land. These adventurers who had come to the Paraense Southeast, not they had had its materialize desires, therefore, had found a strong control of the land, as much on the part of the State, as for other agents, such as: one who holds legal titles to property, squatters and indians. Thus, they had started to be part of the group of the excluded ones, directed to the urban centers, causing with this, the growth of the villages and cities southeastern Paraense, such which occurred in the city of Is Domingos of the Araguaia. Into this context, the change of agricultural Brazil for the urban industrial, according to Corra (1989), transformed and created a new dynamics in the process of production of the domestic territory, in which the Amaznia suffered the biggest modification amongst the Brazilian regions, therefore, it passed to be seen not more through images constructed for stories of researchers that considered this region, as: green hell, eldorado, lost paradise.
