Elaboração de um roteiro interpretativo para trilha de ciclista da Florestal Estadual Edmundo Navarro de Andrade, Rio Claro/SP

The State Forest Edmundo Navarro de Andrade (FEENA), Rio Claro/SP has a huge potential for cyclists tracks; the Unit already have a trail at the principal entrance, passing by firebreaks bordering the towers quadrants and finishing at the municipal road. This work aims the ambiental interpretation of this trail already established and implant activities planned before at the public use program of the State Forest according to the management plan of the Unit; to interpret the tracks for mountain bike cyclists; promote the conservation of natural, historic and cultural resources of the Forest. At the present work has been accomplished the Ambiental Interpretation through the panels, containing the characteristic native flora and fauna, the existing water resources at the Unit and also the representatives individuals of the exotic arboreal species, found around the trail. Ten points were chosen for interpretation, therefore, for preparation of the script it was considered besides the bibliographic literature, experiences of project team members at FEENA, Unit Management Plan knowledge relating the gaps in the public use program and field work. The panels contain figures and texts about the chosen topics, to promote a language easily understandable to the visitor and concomitantly, inform to the population who attends the Unit, increasing this way the user satisfaction

Áreas de preservação permanente (APP) na sub-bacia hidrográfica do córrego do Marimbondo, Jales (SP): um estudo das condições ambientais

This work aimed to carry out a study of the environmental conditions of the Permanent Preservation Areas (PPAs) in the sub-basin of Marimbondo Stream in the city of Jales (SP), through remote sensing techniques and taking as the basis Brazilian environmental legislation, the Forest Code Federal Law Nº 12,651/2012. Permanent Preservation Areas are inserted intrinsically improved conditions in the quantity and quality of water in the areas of springs and along water bodies in rural properties. Therefore, we also carried out studies on the new Forest Code compared to the old Federal Law Order no. 4771/1965 and the observation of its application in the area of sub-basin as well as carrying out the simulation. The results of this research allowed toverify the need for direct implementation of the monitoring measures with the Forest Code, and this water management tool in Brazil, which will ensure sustainable management practices of land use and land cover, with direct benefits to water production, mainly for public supply. Also there was a greater need for involvement by the public actors, the Basin Committee of the São José dos Dourados and the municipal government of Jales, in order to truly act aimed at the protection and maintenance of the water body Stream Wasp

Estudo comparativo da proteção da rede secundária de uma distribuidora de energia elétrica utilizando chave fusível e seccionalizador monofásico

The objective of this work is to conduct a comparative study between the fuse key and the single-phase seccionalizador, which are protective equipment used in an electricity distribution networks. This study has also the purpose to reduce the number of electrical power breakdown. Distribution networks are not free from faults, disturbances and failures, then the occurrence of adversities on the network, which may be transient or permanent faults, results in the interruption of electric power. Thus, there are protective systems of distribution networks, which aims to ensure that the electric system continues to function. The incidence of transient faults in the distribution network of this electricity company was used to generate immediate shutdown of customers due to the bad use of fuses as protective equipment by the reclosers. With the use of the fuse switch in the distribution network, there was the immediate shutdown of customers, however, using the single-phase seccionalizador as protective equipment by the reclosers, there are three attempts to restart the electricity power. As the attempts to restart the electricity power are able to eliminate a transient fault, not causing shutdown of any costumer, with the implementation of single-phase sectionalizers to replace the fuses, the number of company shutdowns due to transient faults was reduced by 47.6%

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
