Sistema de gestão ambiental: subsídios para a implantação em uma estação de tratamento de esgoto a partir da análise crítica de estudos ambientais prévios

The process of environmental impact assessment (EIA), in the extent of previous environmental studies, has as one of its functions to provide subsidies to the actions of environmental managment of enterprises. However, the proper estructuring of programs that allows to support this managment does not often occurs. This research sought as one of its objectives to evaluate in which extent the process of EIA can be a subsidie for the EMS, providing basic elements of this system. In addition, more specifically, the research had as one of its objetives the development of subsidies for the implantation of an Environmental Managment System (EMS), based on the model of ISO 14001 (2004), for a sewage treatment plant yet to be constructed in the city of President Venceslau / SP. In order to achieve theses objetives, a discussion was held based on the evaluation of environmental studies available in the library of Cetesb / SMA. Still, for the elaboration of subsidies for the EMS of the treatment plant, the research was focused on the structuring of environmental management program, based on the information contained in its Preliminary Environmental Report (PER). The research had as one of its products, the development of subsidies for the planning and control of the environmental aspects and impacts and for the environmental program of the enterprise, based on the use of environmental indicators. It was concluded, based on the results that, in general, the previous environmental studies analyzed showed little emphasis on the phase of development of structured environmental programs that offer guidelines to achieve the desired results for the environmental performance of the company.

Estudos estruturais por difração de raios X de fosfolipases A2 em presença de íons com importância funcional

Snakes from Bothrops genus are responsible for more than 90% of the ophidian accidents in Brazil. One of the main complications from this kind of accident is muscular necrosis, which is related to the action of phospholipases A2 and metalloproteases, two groups of enzymes found in the venom of these animals. Although this complication cannot be solved by serum therapy administration, a great number of studies have been performed with the attempt to know the pharmacological sites of these toxins aiming, in the future, the development of complementary treatments to serum therapy. This work proposes structural studies of bothropic phospholipases A2 (PLA2s) in the presence of ions relevant to their activity, using the X-ray crystallography technique. Recently, it was demonstrated ions, as manganese, calcium and others, interfere in the biological activity of the PLA2s. Particularly, Lys49-PLA2s in the presence of manganese ions have miotoxicity reduced. Asp49-PLA2s show catalytic activity dependent of calcium, although structural studies with a miotoxic Asp49-PLA2, BthTX-II, suggest a possible catalytic mechanism independent of calcium. Therefore, co-crystallization of BthTX-II in the presence of calcium ions and of PrTX-I in the presence of manganese ions were performed. Comparative structural studies among obtained results and others already published in the literature were performed aiming a better understanding of the structure-function relationship of these toxins. The BthTX-II with the presence of calcium do not show this ion in the loop of coordination of calcium, presence necessary to develop the catalyses. After comparison of this model with the native one, only one distortion was found, but no apparent relationship with the residues responsible for its activity. In the PrTX-I structure, regions candidates of manganese ions were also found... (Complete abstract click electronic access below)

Análise comparativa dos estudos de impacto ambiental (EIA-RIMA) de projetos dutoviários no Brasil: estudo dos gasodutos Paulínia-Jacutinga, Rio de Janeiro-Belo Horizonte e Urucu-Porto Velho

Pipelines are linear construction that intersect several environments, requiring integration of environmental and technical aspects in its various elaboration steps. Environmental impact assessment if made to integrate the environmental information to enable environmental characterization, possibility identify previously fragilities of environment what contributes to the safety forecast of the significant impacts. These studies shall consider superimpose of the elements and the worsening of critical situations that already exists. In this way, meet and analyse informations about the environmental impact assessment, constructive aspects related to pipelines transport and get environmental impact studies of the case studies, providing the student a critical vision for the discussion of the apropiate balance between description and analysis, methodological rigour and the interface between construction and the environmente with inserts. Performing the critical analysis of methodologies and applied criteria for the environmental diagnosis and impact identification, search improve the methodologies for elaboration of environmental impact studies for linear construction, particulary pipelines, minin conflicts and giving security for the license process. Await provide subsidy to direction data collection, for choosing environmental indicator and for the prognosis and indentification of impacts.

Estudos sobre o subdesenvolvimento capitalista: as teorias de Paul A. Baran, Andre G. Frank e Ruy M. Marini

The underdevelopment is a high relevance subject in researches and studies for the general social sciences. In this monographic paper, the marxist analysis perspective of the phenomenon approached is considerate of great importance to make a deep overlook, historical and structural, about the origins and solutions possibilities for the issues caused by it over several countries. Has been done here a theoretical analysis of three studious marxist authors of the subject: Paul A. Baran, Andre G. Frank and Ruy M. Marini. How they thought underdevelopment? Which were their scientific contributions to this theme? The main goal of this paper is to do a comparative analysis of these authors, synthesize their considerations about the underdevelopment issues and organized a theoretical and conceptual framework for a better understanding of the matters in capitalist development/underdevelopment relationship. To accomplish that, we elected four variables that supports this comparative exercises, they are: the origins, the causes, the consequences and the way-out of the underdevelopment conditions. This monographic work was made through studies of some principals books and articles of the cited authors as well as the reading of others authors that commented their theories and concepts. The considerations about the underdevelopment vitality under a world capitalist logical, rescues the debate on the transformation of this entire society project for another, been this movement the only way possible to reverse the path of the world people’s history and the major part of humankind that still lives into the “necessity kingdom”

Pós-processamento de formas de ondas oriundas de descargas atmosféricas no Centro de Estudos de Descargas Atmosféricas e Alta Tensão (CENDAT) – IEE/USP

Atmospheric Discharges are responsible for several lost in the electrical system therefore it´s done studies to find ways to reduce the problem caused by discharges. This branch of engineering is necessary the gathering, stock and analysis of large quantity of data to validate or refuse the many studies produced about it The CENDAT proposed a project to collect data on induced voltages in distribution lines and current waveform of the lightning, but a difficulty that arose was the accumulation of data due to lack of manpower available to catalog all the data collected. Thinking in this difficulty, the engineer Acacio Silva Neto CENDAT´s researcher with trainees began to develop a program to solve this problem.

Utilização da instrumentação virtual em Labview para criação da interface gráfica do amplificador lock-in utilizado em estudos fisiológicos a partir da comunicação via porta serial

This work presents the development of a graphical interface to the Lock-in Amplifier, which is used in physiological studies on the motility of the gastrointestinal tract in rats and signal processing. With a simple and low cost instrumentation, the resources offered by the virtual interface of LabVIEW software allows the creation of commands similar to the actual instrument that, through communication via standard serial port, transmits data between a PC and peripheral device performing specific and particular needs in the amplifier. Created for the lock-in amplifier model SR830 Stanford Research Systems, the remote manipulation gives the user greater accessibility in the process of configuration and calibration. And, since the software is installed, there is the advantage of eliminating the need of purchase new devices to upgrade the system. The commands created were made to perform six basic modifications that are used in routine of the Biomagnetism Laboratory. The instrumentation developed has the following controls: Amplitude, Frequency, Time Constant, slope low pass filter, sensitivity and offset

Estudos exploratórios sobre propriedades térmicas do compósito cimento-polpa celulósica(CPC)

The search for a more aware use of available raw materials has led to a need to create more sustainable products. The use of natural fibers to reinforce cement, for instance, has been widely studied in the past decades because of the possibility that they can improve material properties such as thermal resistance and to compression, besides conferring a decrease in their total weight. This present study aimed at to conduct preliminary studies on the thermal resistance of the composite cement - Cellulose Pulp, using waste from the pulp and paper industry. Through experiments, it was found that the composite manufactured using the ratio 30 % Portland cement and 70 % pulp, showed satisfactory results regarding its thermal resistance, so it could be considered as a potential thermal insulation material, for use in constructions

Diretrizes para execução dos estudos geológico-geotécnicos e ambientais voltados à implantação de dutovias

Due to the new discoveries of oil and gas reservoirs, and also the increasing production of bio-fuels, the brazilian general pipeline system is being vertiginously extended. On the other hand, there is a lack of clear parameters that would allow a better utilization of the geological-geotechnical studies in the process of environmental licensing of pipeline systems. Therefore, this paper presents guidelines that would orientate the environmental licensing procedures to build pipeline systems, and also the geological-geotechnical studies that would support the characterization of the physical context. The method applied in this study consisted in the existing data survey and in their organization, analysis and review. In doing so, there is a well-subsidy integration of the many steps of the pipeline system implementation, the required environmental licenses and the investigation methods of the correlated physical context. As a result, it’s presented a flowchart of the guidelines, detailing the interaction between the environmental licensing, the geological-geotechnical studies and the phases of the pipeline’s project.
