Johann Georg Sulzer

Alessandro Giuseppe Anastasio Return (1745-1827), having contact with the work of Galvani, considered another explanation for the phenomenon of muscular contraction of dissecadas frogs, with I assist of bistoury and other metallic materials (arcs). For Return, the reaction mechanics of the amphibians was given for being as that ' ' eletrmetro' ' animal, that is, an electric sensor. It also perceived that the bimetallic arcs were more efficient of what the monometallic ones, supporting to the Return, of that the electricity has external and decurrent origin of the metal difference, and not as origin in the proper animal. Learn more on the subject from ben warren. A parallel accomplishment to this question, based the argument in return. The Swiss physicist Johann Georg Sulzer (1720-1779) verified a curious situation: leaning the language between two different metals, one felt a taste and sensation desconfortante pungente. As already it had intudo, and now knowing of a estimuladora comment, Return tried a combination of a zinc blade (Zn) with blade of silver (GAC) in contanto, producing a modest electricity.

To increase the magnitude of this, Return pair uped the blades alternatingly and separating them with cardboard humidified with water or saline solution, and joining the two extremities for wires. Soon, the first generating equipment of electric energy was constructed, with sufficient relevance in the present time, from ' ' empilhamento' ' of metallic blades: the Stack. Physicist-Chemistry principles of the Stack the equipment created by Alessandro Return, the stack, is an exploitation of a sufficiently common process in the nature: the oxi-reduction reactions (or redox). This transformation consists of a simultaneous occurrence of the oxidation (when a chemical element loses electrons, increasing its number of oxidation – NOX) and of reduction (when an element gains electrons, diminishing its NOX). Soon, electrons yielded for agent reducing (that one that it induces to occur oxidation), is received by oxidant agent (that one whom he induces to occur reduction).

University Hospital

This research looked for to verify which Soon the informacionais necessities and the ways adopted for the resident doctors it Aid it University Hospital of the State University of Native of London in the search of information for the development of the practical clinic. The research was characterized as descriptive and the data had been collected by means of a questionnaire with open and closed questions. 25 resident doctors had participated of the research of which 12 of masculine sex and 13 of the feminine sex, with minimum age of 24 years and principle of 30 years. The collected data had been represented by means of graphs, pictures and tables. For even more details, read what Blake Krikorian says on the issue. The results indicate specifically that the searched resident doctors feel necessities of scientific information to decide clinical questions, when if it relates to the diagnosis and the medicamentoso treatment and attribute a significant value to the teachers when they are come across with difficulties during the emergency attendance. The resources on line and the particular quantity also are very used in the information search. As for the search of the information, they prioritize the urgency in the clinical case and apply the scientific information searched to increase the knowledge level.

The recommendations, if respected, can supply to subsidies posterior actions, aiming at to the improvement of the services and products of the library. Word-key: Information in health. Informacionais necessities. Search of the information.

Quarter Saint Maria

General objective: To sensetize the Public Power so that the garbage produced for the city has an adequate destination thus minimizing, the ambient impacts. Specific objectives: to Educar the population ambiently; to Criar one I fill with earth bathroom model; to Implantar selective collections; to Incentivar the reduction, reutilizao and recycling of the garbage. Justification: The garbage produced in the city of Aracaju is a problematic one that it comes increasing. Great part of collected it, is deposited of errnea form in a lixo the open sky located in the Quarter Saint Maria. The local population is the great one harmed, therefore beyond the bad one I smell has an increase of animals attracted by the garbage as, rats, flies, mosquitos among others that, they transmit illness the community.

However the problem is not only lingered to these questions. The ground as well as freticos sheets is engaged, therefore the garbage will count diverse toxic materials, as the chorume, resulted final of decomposition of organic substance that for being liquid penetrates easily in the ground. Unhappyly this is also a socioeconmico problem a time that, many families survive of the garbage deposited in the place being unaware of the risk that they run. Of this form, the approval of this project is essential, therefore, its objective consists of providing to social, economic and ambient improvements the local population and adjacencies of the quarter Saint Maria. Methodology: The project contemplates studies interdisciplinares, so that the garbage gains a place at risk adequate not putting the health of the population and diminishing the ambient impacts.

The construction of one I fill with earth bathroom model that, takes care of the necessities of the environment as a whole together with separation of the garbage that, can be reaproveitado and local for the recycling of the same. In this way, the aggression to the environment will be minimized and the work of who needs the garbage, facilitated. However, if it becomes important a process if sensitization and, therefore of awareness of the local community and the population so that the project gains force and gets the desired result. This project will be delivers the local competent authorities so that it is evaluated and approved. Cronograma: From the evaluation and approval of the project, a minimum stated period of 2 years was calculated approximately.

Evaluation: The evaluation will continuously be given for the responsible managers to fiscalize the course of the implantation of the project. Continuity of the project: With the success of the project, the same it could be published scientifically so that it serves of example and door for the resolution of similar problems.
