Potencial de contribuição e importância socioambiental dos 'catadores autônomos' de Rio Claro (SP) para o programa de coleta seletiva municipal

The Urban Solid Residues are the rests of human activity, popularly known by trash and considered by population like useless, undesirable and disposable. On the other hand, for the waste pickers, solid residues are the beginning of a cycle: they see in the other's people trash the only income, an economic value. Currently, in brazilian cities, one million collectors act, alone or in cooperatives, socially excluded by the work they do. The National Policy of Solid Residues (PNRS), instituted in 2010, established guidelines to the execution of integrated residues management, with should be practiced by city halls and other governmental institutions. This policy has, besides other things, goals of residues reduction and inclusion of waste pickers in the mechanism of selective collect and recycling. However, this and other public policies created for residue management are benefic only for cooperated waste pickers. That could negatively affect most of this class, since 90% are waste pickers working in a precarious way on the country's streets. This study has for objective show that most of waste pickers that work in a precarious way on the brazilian territory has a huge potential for the solid residues recycling chain and how they should be valued for the environmental services they provide, so they can be included with dignity on the society, ensuring economic and social benefits for this workers. The methodology adopted was based on the amount of residue collected by the 44 cooperated members of the Rio Claro‟s waste pickers cooperative to estimate the potential of collect and recycling did by 210 autonomous waste pickers who are active on city streets. It was observed that the cooperative collects the equivalent of 10.2% of all recyclable residues generated by city population. However, with the potential that these autonomous waste pickers have, which together could contribute 465 tonnes of solid residues per month, or 5,570 tons a year...

O papel dos conflitos no desenvolvimento do juízo moral em crianças da educação infantil

This research sets up as a reflection on the development of moral judgment in children from 04, 05 years of the Early Childhood Education with the main theoretical reference the studies of Jean Piaget (1932/1994) on the subject. To this end, we conducted a case study in order to understand what types of conflicts that arise among children in the school of early childhood education and how the teacher seeks to solve them, or not assisting in promoting the moral autonomy of the small. Behaviors and conflicts observed were described and analyzed by correlating them to the practice of the teacher in the classroom that is the case study. We found that conflicts are avoided and unwanted by the teacher and, when they arise, are quickly resolved through attitudes centered educator without enable dialogue and reflection among the children involved. In this sense, we infer that the teaching practice focused on the development of moral judgment of children showed failure and ineffective. As a result of feedback from the first phase of this research we deem necessary to investigate about the training of teachers of early childhood education in relation to theories that deal with the development of moral judgment in children of this educational stage and identify the implications that such training reflects teacher practices in. We hope that by making such reflection can contribute to the debate on the need to educate morally in early childhood education, whose main objective is to promote the integral development of children

Aplicação da Simulação de Monte Carlo no estudo de testes de fadiga em rodas agrícolas

Due to the increasing demand from clients and the search for better performances in the heavy vehicles industry, a progressive evolution in technology in a general way was needed. This paper uses a scientific method to validate, prior to its manufacture, the project of an agricultural wheel for sugar cane harvesters. Monte Carlo Simulation is used in conjunction with Finite Elements Method, in order to simulate the wheel's behavior in a cornering test, identify possible failure regions and get an estimate for its life under fatigue. To this end, test conditions according to EUWA Standards were simulated and obeyed, relevant to fatigue. Simulation results were interesting, according to industry experts involved in the project and manufacture of the product in question, and have provided important elements for the decision making regarding improvements that could be made on the product project before its execution

Análise de sistemas de proteção por redundância e bloqueio de energias contra acidentes em prensas e equipamentos rotativos

This monograph presents the main objective of analyzing the redundancy protection systems of protection for redundancy and block of energies against accident in presses and rotating equipment. After understanding two specific goals, on this case, show the systems of protection against accidents in rotating equipments, presses and similar; and discuss the vulnerabilities of current systems of protection against accidents in presses and similar, we will propose a system of autonomous redundancy of Programmable Logic Controller (PLC) operating simultaneously taking online in the event of failure of one of the two. The methodology was worked through a revision of a variety of bibliography, and interpretation of national and international standards as well as access to research on systems, practices used in industrial and companies supplying products and of companies and energy blockages solutions

APR e FMEA em trocador de calor de bomba

The modernization of the world made the speed, accuracy and reliability of all existing processes become increasingly necessary. For this evolution to occur every day, the evolution of the equipment was strategic, but not as much as needed. It is necessary for such equipment to ensure its function and, in case of failure, an early diagnosis to prevent loss. Therefore the evolution of maintainability and reliability in equipment is also paramount. Thus, the growth of forms of maintenance was driven by this scenario, forming maintenance philosophies. Among many, there is the RCM, which have its focus on the identification, parameters development and performance preview. One of those methodologies from this idea is the FMEA, process that has been studied and implemented this work, aiming the anticipation of failure modes and guidance for the use of a heat exchanger and a pump. This implementation has the aid of another process of RCM, the PHA, which was also shown and implemented, these results being used to start the FMEA process. The results show the activities with the highest chance of failure, presenting also the measures to be taken to avoid or minimize them. It is shown, in this paper, concern with the valves because they maintain control and system security, and its flaws related to accidents with possible danger to people and the whole system, emphasizing the priority of action
