The Country

The same must have an area sufficient to install the balance and that one auxiliary equipment with which is interacted in the processes of pesaje. Of equal way one is due to anticipate the space required by interconnection cables, electrical current, connection to the information system, the printer, etc. 3. To avoid that in the vicinity they are installed equipment that produces magnetic fields high or vibrations like centrifuges, electrical, compressing motors and generators. 4. To avoid that one is under the direct influence of the conditioned air systems solar light and airflows. 5.

To have an electrical taking in good state, equipped with pole to provided land of switches, whom the country or the laboratory fulfills the effective electrical standardisation in. Operation of the electronic balance The operation of a modern electronic balance clearly is defined in the manual of operation that provides the manufacturers. Generally the following procedure is due to fulfill: 1. To allow that the balance balances its conditions with those of the atmosphere where of finds installed. 2.

To allow that the balance is preheated before initiating the activities. Normally it is enough that the same is connected the system of power supply. Some manufacturers suggest lets themselves pass a period of time of at least 20 minutes, from the moment in which energiza until the moment at which the use of the same begins. The analytical balances Class I require at least 2 hours before initiating their use. 3. To verify that the balance is calibrated. The electronic balances generally have a calibration done in factory, stored in the memory, which can be used if it is not had masses of calibration. If it is required to realise the calibration, one is due to have calibrated masses to be able to carry out the procedure that indicates the manufacturer. The calibrated masses used must fulfill or exceed tolerances ASTM.

Copenhagen Consensus

All remember. Rio De Janeiro hosted Echo, Conference of United Nations on the Environment and the Development. They searched half to conciliate the partner-economic development with the conservation and protection of ecosystems of the Land. some important documents had been produced. The Letter of the Land, based on the principles of that we must respect and take care of of the life community, to keep the ecological integrity, to promote social and economic justice, democracy, not-violence and peace. The conventions of Biodiversity, the Desertificao and the Climatic Changes; The declaration of principles on forests. The Declaration of the River on Environment and Development, standing out the beginning of the support. Agenda 21, a base so that each country could elaborate its plan of preservation of the environment.

Thousands of films, announcements and news articles had been made after this, valuing the nature mainly. The lesson that was incomplete: research of the Ministry of Environment, carried through in 2003, showed that 67% of the Brazilian population do not incluam the human being in its slight knowledge on ecology. little people knows today, until, that ' ' ecologia' ' it is the study of the place where if it lives. In the populated regions, where ' ' algum' ' it lives. But a more including knowledge was express of impactante form. The Copenhagen Consensus (2004), that it congregated nine economists world-wide of the great prestige, concluded that the main ambient problems of this planet were, for the order, the AIDS, me the nutrition, the trade barriers and the malaria.

More recently, in 2008, Jeffrey Sachs, special council member of the Special Secretary of United Nations in the Goals of Development of the Millenium, published ' ' The wealth of todos' ' (New Border). Sustainable development, according to it, ' ' it means prosperity globally shared and ambiently sustentvel' '. To reach it, we need technologies that allow to more combine high levels of prosperity with ambient impacts basses, we must stabilize the global population, especially in the countries poor and is mandatrio to help the countries poor to escape of the trap of the poverty with global politics. The ONU now prepares the Rio+20, that will offer a possibility to the world in the fight against the poverty, according to undersecretary-generality of Economic and Social Subjects, Shah Zukang, who complements: the meeting will try to close an agreement of transistion for ' ' economy verde' ' , that it will have to help to reduce the number of poor persons in the world. Finally, we place the human being in the center of the attentions. It does not have nothing that degrades more the nature of what the misery and the illness.
