Universidade e educação ambiental

The society consists of the inter-relations between diverse symbolic fields of performance, where some agents if identify for values, habits and goals. The present thesis analyzed, taking for base the Theory of the Social Field of Pierre Bourdieu, the ambient field and the university, leaving of the principle that the university is one of the propitious places for the quarrel, study, knowledge elaboration, and that the ambient education is one of the ways of dissemination of knowledge and action in favor of the ambient question. It was looked to contextualize and to identify the main factors that configure the university while a social field, and to evidence the conflict and connector links with the ambientalism. It is perceived university as space of tensions, whose produced capital stock in the academic scope must be enough convincing in the direction of the social transformation, of the expansion of conscience, the critical matureness, and thus to appear as agent of social transformation. The joint between the diverse social fields, promoted for the university, will be able to contribute for knowledge formularization that can consist base for elaboration of politics and programs to answer to the problems of the society contemporary. It has the inter-relationship between the two fields, however, this relation still is fragile, needing that a continuity practical social that they make possible that the ambient question is part of the culture of the university. This will be able to give with the intensification of the actions and the inclusion of the ambient questions in the communication mechanisms and administrative management. To surpass discontinuities caused for changes of groups leading and for interests politician conjunctural are necessary that they create habitus, what passes for the institutionalization of practical and the constitution of a culture that the agents allow if to reorganize defending the interests of social transformation front to the economic interests, as much in the university how much in the ambient field

Análise tecnológica sobre os aspectos ambientais de empreendimentos hoteleiros da Praia de Ponta Negra Natal/RN: um modelo de sistema de gestão ambiental

The present work aimed the elaboration of an environmental study focused on the hotel sector in order to present an analysis of the environmental aspects of Ponta Negra Beach, in Natal, RN, Brazil and also the aspects of the small and medium hotels existing in this area. By means of this work, it is possible to elaborate a model of a simplified System of Environmental Management which can attend to the exigencies required by NBR ISO 14001: 2004, as well as to present economical viability and possibility to be implemented in a way that hotels may converge to the sustainable environmental development of the tourism in Ponta Negra Beach. The research methodology presents itself divided into three items: execution of the environmental characterization of Ponta Negra Beach, by way of technical visits and interpretation of satellite images and cartograms of the main environmental characteristics of the region; execution of the work already made concerning the development, application and interpretation of the evaluation of the environmental aspects of each hotel, considering the hotels and the period of data collection, these used in evaluation, research instrument and a description of the procedure utilized for the analysis of the collected data and the utilized methodology for the elaboration of a model of a simplified System of Environmental Management. In a general way, it has been concluded that the practices executed by hotels in Ponta Negra Beach are impact-like and harmful to the environment. The simple implementation of analysis procedures and control of the environmental aspects could suggestively contribute to the reduction of environmental impacts promoted by the hotel section at this beach and in the nearby areas. It had been noticed that the study contributed to the sensitization of managers concerning the environmental problems since, in many other times, the detected problem was, in fact, the non-acquaintance about the environmental aspects and impacts from those hotels administrators, because of the lack of surveys and studies about the theme. It had also been noticed the arousing of a possible environmental attitude from some managers

Fonte de energia alternativa: um estudo sobre a percepção ambiental, social e econômica do biodiesel com docentes do Centro de Tecnologia do gás da cidade de Natal RN

Meaning fuel and renewal energy source s derivative additives, the term biodiesel exists in Brazil since 1980, when it was signed its first patent by Expedito Parente. Since then, its importance has grown gradually due to the worsening of the ambient problems, since its use has became a highly promising alternative to the pollution decrease, as in the carbon dioxide issue as with the smoke and sulfur oxide. In Brazil, it was created the National Program of Production, whose objective is to insert the new product in the country s energy matrix, strengthening the economy and creating new employment opportunities, being an important product to the national energetic independence, since Brazil still imports diesel to its domestic consumption. This study aims to identify the ambient, social and economic perception of the teachers from the Technology Center of Natal city (CTGÁS-RN) to the biodiesel. For that, it was used a questionnaire closed questions, organized in the likart scale, directed to the tree spheres of the research analysis, the biodiesel and its social, ambient and economic nuances, totaling 31 questionnaires full answered. In its objectives, the research was descriptive and in its approach it was qualitative. To the data analysis it was used statistical tools (Statistic software, 6.1 version and Microsoft Excel 2003). The research revealed the predominance of the ambient aspect in the sight of the teachers, followed by the social ones. The economic factors represent a minor percentage in the analysis when compared to other

Diagnóstico ambiental da gestão e destinação dos resíduos da construção e demolição (RCD): análise das Construtoras Associadas ao SINDUSCON/RN e empresas coletoras atuantes no município de Parnamirim - RN

Surveys carried out in many Brazilian cities have shown that the CDW Construction and Demolition Waste, in some cases, represent more than 50% of the mass of urban solid residue. Municipalities have struggled to manage in an effective way huge quantities of CDW generated every day and solve the problem of the illegal dumping in an inadequate area, which compromise the quality of life of the population as a whole, thus causing serious problems concerning social-environmental and sanitary. This paperwork was meant it carry out environmental diagnosis of the management and the final destination of the CDW in the city of Parnamirim/RN. The methodology used in this work constituted in the bibliographical research, conducted to give support and fundaments to the subject in question, identification of the main places of legal and illegal dumping, identification of the environmental impacts caused by the irregular deposition of the CDW, valuation of quantity and quality of the CDW and perception according to the Environmental Legislation. The necessary data for the elaboration of this study were carried out through the appliance of questionnaires with open and closed questions, applied to 14 (fourteen) Real Estate developer companies associated with SINDUSCON/RN and 05 companies that deal with the transportation and collection of CDW, formal and informal interviews, exploitational visits and photographical records. The collected data went through a statistic treatment being organized into tables and graphs. The main results obtained from this research show that the interviewees hold a medium knowledge of the specific Environmental Legislation; do not have an effective model of environmental management, resorting to only reusing CDW; that the reusing of CDW is not substantial, as much as the possibility of recycling has a minimal consideration. It was also verified that a considerable percentage of interviewees affirmed to send CDW to illegal and inadequate locations. It is expected that such study can be used as an important tool to subsidize the public administration in the pursuit of solutions which could bring benefits to society and the environment

Impacto urbano ocasionado por empreendimentos da construção civil no entorno da zona de proteção ambiental (zpa-6), Vila de Ponta Negra, Natal/RN

The process of urbanization in recent decades has generated considerable seriousness of problems relating to the use and occupation physical environment of cities. The concentration of population, economic activities and technological standards have reinforced an existing urban environment highly degraded as a consequence of the development style that leads to the predatory use of natural resources. In this context, cities as centers of production and consumption, have the most serious problems of environmental degradation. This study investigated the impacts of the municipal building projects to large-scale vertical in the town of Vila de Ponta Negra, Natal-RN, given the proximity to the Environmental Protection Area (ZPA-6) and considering its environmental importance , scenic, landscape and tourism for the city of Natal-RN. The fragility of the licensing process and the failure of the assumptions in the analysis, objective and subjective, for the granting of environmental permits for the building construction projects, specifically those set out in the surroundings of the Environmental Protection Area (ZPA-6) and fundamental importance of landscape and tourism for the city of Natal, has aroused the concern of local people in and of itself the Government, faced with the probable impacts that will affect greatly the Vila de Ponta Negra. The methodology used to achieve the intended objectives will be the literature review, questionnaire to the surrounding population and the Government, as well as findings on the spot, through the photographic record. The beneficiaries of the license, if the entrepreneurs, have been affected because of the granting of licensing act of investing large amount of capital in the works. Additionally, with distrust of the population, since they are to discredit the public system of environmental management have guessed by the probability of imbalance to the environment and structural damage to the Vila de Ponta Negra, where such failure to support energy, lack of regular supply of water , lack of sanitation and access roads sufficient for the flow of motor vehicles in these areas, among other factors. Thus, this work will contribute to the diagnosis and solutions to the problem in question, so that the Government will effectively fulfill its social management of ecologically balanced environment of continuing urban development in Natal, Brazil

A influência do marketing ambiental na decisão de compra dos consumidores de produtos orgânicos

The search of the man for more comfort and one better quality of life led to an increment of the production of goods and services, that results, almost always, in aggressions to the nature and to a reduction of this same quality of life. The concern with the ambient problems appears as an important element regarding the material and economic growth and of the quality of life. With this scene a new question, the Ambient Marketing appears. Although the marketing concept to be well ample, the companies use the term ambient marketing to make reference what in fact, many times, are a more specific activity of ambient communication. The ambient communication is a new form to communicate used for the companies with the objective to get advantages of its competitors ahead, since the competitiveness by means of the o price, the stated period and the quality if becomes extremely incited. In view of the current competitive market, where the organizations need distinguishing to get greater have detached front to the competition, and the fact of the society to be each time more worried about the environment and the impacts that the companies cause it, the ambient communication has been used as form to convince its customers. Of this form, she evaluated herself, through a exploratory research and qualitative, the influence of the use of the ambient communication in the decision of purchase and of that she forms the companies when using of this communication can add value to its product. The results had indicated that 77% of the interviewed ones had heard to say on marketing or ambient communication and that the television is main the media for this knowledge, a time that 90.9% of the respondents had affirmed to have seen propagandas of directed products of consumption to the ambient question in this way. In fact, the concern with the environment demonstrated for the companies has its impact, therefore 84% of the respondents had told if to sensetize with this fact. However, only a lesser number of people, 70.5% answered that this concern really influences in its decision of purchase

Efeitos do envelhecimento ambiental acelerado em compósitos poliméricos

The advantages of the use of vegetable fibers on the synthetic fibers, such as glass fibers, in the reinforcements in composites are: low cost, low density, good tenacity, good thermal properties and reduced use of instruments for their treatment or processing. However, problems related to poor performance of some mechanical natural fibers, have hindered its direct use in structural elements. In this sense, the emergence of alternative materials such as hybrids composites, involving natural and synthetic fibers, has been encouraged by seeking to improve the performance of structural composites based only on natural fibers. The differences between the physical, chemical and mechanical properties of these fibers, especially facing the adverse environmental conditions such as the presence of moisture and ultraviolet radiation, is also becoming a concern in the final response of these composites. This piece of research presents a comparative study of the strength and stiffness between two composite, both of ortoftalic polyester matrix, one reinforced with fibers of glass-E (CV) and other hybrid reinforced with natural fibers of curauá and fiberglass-E (CH). All the comparative study is based on the influence of exposure to UV rays and steam heated water in composites, simulating the aging environment. The conditions for the tests are accelerated through the use of the aging chamber. The composites will be evaluated through tests of uniaxial static mechanical traction and bending on three points. The composite of glass fiber and hybrid manufacturing industry are using the rolling manual (hand lay-up) and have been developed in the form of composites. All were designed to meet possible structural applications such as tanks and pipes. The reinforcements used in composites were in the forms of short fiber glass-E quilts (450g/m2 - 5cm) of continuous wires and fuses (whose title was of 0.9 dtex) for the curauá fibers. The results clearly show the influence of aging on the environmental mechanical performance of the composite CV and CH. The issues concerning the final characteristics of the fracture for all types of cargoes studied were also analyzed

Limonologia e qualidade ambiental de um corpo lêntico receptor de efluentes tratados da indústria de petróleo

Environmental pollution has become a subject of public interest throughout the world. Not only have developed countries been affected by environmental problems but also the developing nations have started to suffer from the serious impacts of pollution. Within this context it is necessary to collect simplified environmental data to assist in the management of water resources by the appropriate authorities. These data are obtained through an environmental index that allows a space-time comparison of points distributed in the same aquatic body, or between different water bodies, for physico-chemical and bacteriological parameters. The aim of this present study was to determine the environmental status of the Lagoa de Baixo at Guamaré/RN, where a production unit of PETROBRAS RN/CE is located. For this purpose the Water Quality Index (WQI) was used in both an add and multiply form, the Trophic State Index (TSI) and the Environmental Quality Quotient (EQQ), as well as determining the concentrations of metals. The average values obtained for the WQI, in its two forms were 68,67 and 62,76 respectively which were inside the good qualification. According to the TSI the lagoon showed characteristics of a middle trophic state, and an impact level of regular as determined by the EQQ
