In addition, over time, standards of life are changing, so "Filling" was built 30-50 years ago, the building no longer meets the modern needs of its inhabitants. So, if in former times the total power of all of the apartment appliances do not exceed 2-3 kW, is nowadays insufficient and may be provided by regulations 7 kW. This means that the whole house-grid needs upgrading, as increased by several times the load to be replaced not only the cables, but also counters the whole automation equipment switchboard. Similarly is the case with heat supply. "Fifty years ago, the mere existence of the house central heating system has already been to a lot of happiness, because in some places we used wood furnace, – said Konstantin , director of thermal automatics Danfoss, a leading global manufacturer of energy efficient equipment for heating systems and heating buildings. – Today, people have different requirements: they want to be able at their discretion to regulate the temperature of air in homes, and this requires a comprehensive modernization of the heating system. Thus, installation of radiator thermostats to all heating batteries have significantly increased levels of comfort, because allows you to automatically adjust the temperature of heating devices for changes in the room. However, to get the best effect, it is necessary set in a house heating unit with automatic weather compensator. This will ensure the heating system in unison with the vibrations of the weather: in the freezing cold in the apartments will be warm and comfortable, and in periods of thaw, their inhabitants will be spared the unbearable closeness and the need for continuous ventilation.


This dispersion of efforts did not hinder that, already in the second half of the decade of 1930, it appeared in Brazil for the first time, even so of still incipient form, an agricultural strategy in the scope of the central government, having as objective to extend and to diversify the farming production of the country, particularly that one destined to the domestic market. The main instrument of this strategy was and would continue to be for much time credits, it agricultural publishes of Creia of the Bank of Brazil. The advantages I credit of it agricultural quickly had been used to advantage by the agriculturists, becoming possible, between 1938 and 1945, not only the great magnifying of the bank credit to the productive sector, but also a considerable growth of the farming production in the same period (SWMRECSANYI; BRANCHES, 1977, p.231).

The period postwar period was called, in the agricultural scope, for the new cycle of valuation of the external prices of the coffee, that if opened in the magnifying deals of it broke world-wide it of 1946, hibernando in this A stage the diversified politics of products and region that prevails in the previous period. The agricultural politics of the federal government in the period basically had been come back toward stimulate the production saw market mechanism to it, with the state intervention acquiring some relevance only at the moments where referring problems to the internal supplying appeared of foods and substances cousins. The exchange, fiscal and credit subsidies for the acquisition of the modern insumos calls of the farming production had contributed substantially for the great increase had in the fertilizer consumption and for the diffusion of the use of tractors and other mechanical equipment, even though of the trucks. These instruments of agricultural politics can be faced as the desencadeante factor of the industrialization of Brazilian agriculture, which started to occur with bigger intensity in the second half of the decade of 1950, also contributing for the great I continue increase that had in offers of products agriculturists entre1946 and 1964.
