Lima, uma cidade entre a aristocracia e a plebe (1950-1980)

The city of Lima has undergone serious changes over the past sixty years. Until the middle of the last century, Lima retained an urban structure similar to that built in the 18th century, during the final decades of its colonial period. This reality began to change with the abrupt onset of migration from the mountain ranges to the coast in 1946. However, rather than changes in its urban plan, Lima underwent a ethnic and social reconfiguration that would bring new color and new cultural and behavioral norms to the Peruvian capital. The arrival of migrants to the city caused a conservative reaction in the local elites, but it also sparked a need for the intelligentsia to develop new ways of thinking about the place of migrants in the space of the city, and on the other hand, to create new representations of the city itself. From being a city isolated from the rest of the country, Lima came to live with a range of cultural and ethnic references. It did so, however, without creating greater opportunities for the integration of the masses within the urban and social logic of the city, thus making clear the separation between the aristocracy and the general populace.

The Ji-Paraná city (RO) it doesn't possess public system of collection and treatment of sewers, being the waters residuárias produced by the local population thrown at sewages. Traditionally, many inhabitants use wells amazon extracted underground water or tubular shallow in the urban zone. The study accomplished in the Nova Brasília neighborhood for Silva (2009) revealed that the local aquifer is strongly contaminated for nitrate, originated of the decomposition of the organic matter deposited at the sewages local maidservants. With the objective of detecting areas with high concentrations originating from organic compositions of septic sewages, geophysical risings were accomplished, later related with analyses physical-chemistries in samples of groundwaters obtained in several wells installed in the Nova Brasília neighborhood, besides of soil samples descriptions in zone not saturated obtained in wells. The results obtained by the geophysical rehearsals they reveal that the polluting feather not migrates through the zone saturated, arriving with relative easiness to the aquifer, reaching in some points, superior depth to 34 m reached by the geoelectrical profiling.
