Física do meio ambiente como disciplina nas licenciaturas em física: proposta de uma unidade didática para ensinar efeito estufa e aquecimento global

In this dissertation we propose a Teaching Unit of Physics to teach content through environmental discussions of the greenhouse effect and global warming. This teaching unit is based on a problem-methodological intervention from the application of the method of the Arch of Charles Maguerez. The methodological foundations of the thesis are embedded in action research and this is structured in five chapters: the first chapter deals with the Physical Environment (FMA) as a subject in Degree Courses in Physics in Brazil, bringing the concern of how this discipline has been taught. We started the first chapter explaining the reasons behind the inclusion of the discipline of Physical Environment in a Physics Degree Courses. Then we did a search on the websites of Institutions of Higher Education, to know of the existence or not of this discipline on curricular. We then analyzed the menus to see what bibliographies are being adopted and what content of Physics are being worked, and how it has been done. The courses surveyed were those of Federal and Federal Institutes Universities. Thus ended the first chapter. Given the inseparability between studies in Physics Teaching and studies on competencies, skills and significant learning, wrote the second chapter. In this chapter we discuss the challenge of converting information into knowledge. Initially on initial teacher training, because even if this is not our focus, the study is a discipline on the upper reaches, therefore, offered to future teachers. Then we talked about the culture of knowledge, where we emphasize the use of a teaching approach that promotes meanings taught by content and make sense to the student. We finished the third chapter, making some considerations on skills and abilities, in order to identify what skills and competencies were developed and worked during and after the implementation of Curriculum Unit. The third chapter is the result of a literature review and study of the radioactive EarthSun interaction. The subjects researched approach from the generation of energy in the sun to topics stain solar coronal mass ejections, solar wind, black body radiation, Wien displacement law, Stefan-Boltzmann Law, greenhouse effect and global warming. This chapter deals with material support for the teacher of the aforementioned discipline. The fourth chapter talks about the arc method of Charles Maguerez; Here we explain the structure of each of the five steps of the Arc and how to use them in teaching. We also show another version of this method adapted by Bordenave. In the fifth and final chapter brought a description of how the method of Arc was used in physics classes of Environment, with students majoring in Physics IFRN Campus Santa Cruz. Here, in this chapter, a transcript of classes to show how was the application of a problem-based methodology in the teaching of content proposed for Physics Teaching Unit from the environmental discussion about the greenhouse effect and global warming phenomena

Conselho estadual de meio ambiente do Rio Grande do Norte: paradigmas, proposições e atores sociais

The environmental movement rises up strongly in the year 1972 with the Stocolmus Conference, in the middle of pressions concerning the environmental preservation, in consequence of the environmental catastrophes. In spite of the fact that, in Brazil, the environmental movement has is institutionalization with the 1988 Constitution, in a way that the councils became democratic spaces, and provided the society’s participation in the management of public policies. In this way, we propose a discussion about the participation and the exercise of the citizenship in the State Council of Environment of Rio Grande do Norte (CONEMA), focusing the glance about the decisory process, as from the expression of the social actors. For that, our research compilate documents of the meetings of the referring council, transcribing the main discussions about the environmental necessities which were important in the potiguar society, and checking how these agents defend their interest during the meetings. We understand, with these informations, the role of CONEMA/RN as a communicative mechanism between State and Society. With the analysis of the informations of the extraordinary meetings from 2007 to 2014, we concluded that the CONEMA is a council where the civil organized society takes part on the decisory process, despite the great influence of the representative actors of public power over the representative actors of civil society. The results of this research confirm the discrepancy between the participation of representative councilors of civil society in CONEMA/RN. The conclusion point out that the civil society representative don’t, yet, assimilate the citizen duty, the responsibility of it1s action, producing, in this way, damages for the legal structure of the potiguar environmental legislation, with serious consequences on the public policy implementation

Estudo da incorporação de cinza e chamote gerado pela cerâmica vermelha ao próprio processo industrial

The ceramics industry generates waste at various stages of that process, defective products, waste from burning solid fuels, among others. This waste is dumped in landfills, garbage dumps or directly on roads, which has a negative environmental impact. This paper presents a study to incorporate the waste of algaroba wood and chamote (scrap pieces of ceramic already sintered), in to the ceramic material for making sealing blocks. The methodological procedures consist in the characterization of chemical and mineralogical residues, raw materials, and physical-mechanical of the formulations of mixes with clay, silt and waste. By pressing test pieces were produced using a pressure of 200 kgf/cm², varying compositions in the range of 0%, 5%, 10% and 15% by weight of residue. The sintering was performed in a muffle furnace, with the temperature levels of 850 ° C, 900 ° C, 950 ° C, 1000 ° C and 1050 ° C. The evaluated physical and mechanical properties were: Water Absorption, Linear Shrinkage Burning, Apparent Porosity, Apparent Density and Mechanical Resistance to Flexion. Analysis was carried out by Scanning Electron Microscopy on fracture surfaces of the specimens. Evaluation of linear shrinkage property drying and firing , water absorption and mechanical resistance to compression of the sealing blocks 5% wood ash residue, sintered at 900 °C hold temperature in the laboratory the products manufactured on an industrial scale. The main results, it was found on the viability of using the residues of algaroba wood and to confer refractory properties of the ceramic product. The main results, it was concluded feasibility of using the ash residues algaroba wood to impart refractory properties to the ceramic product and the residue of chamote, being derived from the own ceramic product not interfere with the properties, when used in a percentage of up to 5%.Since the residue of chamote being derived from the ceramic product itself had no effect on the properties. Studies in the laboratory have shown that the incorporation of up to 5% of these residues may be adopted as an alternative technology to reduce the environmental impact caused by the industrial sector, without compromising the final properties of the material, since the results on an industrial scale showed absorption values 11.66 and 11.74 of water and waste products respectively, within the parameters of NBR - 15,270, since the mechanical strength was 1.25 MPa and 0.94 MPa respectively for products with and without residue, lower than the minimum required by the technical standard that is 1.5 MPa.

As relações de interação e integração entre cérebro, corpo-propriamente-dito e meio-ambiente na constituição da mente consciente

This dissertation will be marked by our proposal to hold a theoretical perspective to the classical mind-body problem, and more precisely for the defense of the idea that consciousness (or conscious mind) emerges from the interaction and integration relationships between body proper, brain and environment. This purpose will lead us to assume an alternative position with respect to the more traditional perspectives to the mind-body problem, ie an alternative perspective not only in relation to the dualistics forms of mind-body, but also in regards to the reductive physicalists, which usually reduces mind to brain. Aiming to support a position that both avoid the idea that mind and body are distinct substances and the theory that the brain explains the consciousness in its totality, we will dedicate an important part of this work to explain how the structure of consciousness depends significantly of the body proper and the bodily information mechanisms as well as the environment and the physiological mechanisms through which we place ourselves in space, in front of us and the other bodies (organic and inorganic). Given that the relationship between brain, body and environment involves different mental levels — from the most primitive and unconscious mental mechanisms until conscious and sophisticated levels — we will proceed to the task of assuming a model to explain in what sense these levels contribute to that our instincts and the most sophisticated dimensions of our mental life are part of the one and the same process, which is why we will structure our argument from the ideia that mind, self, and consciousness are the different hierarchical levels which make up the totality of our psychic life and therefore organic one. Imbued with this conceptual approach, we will advance to the focus of this work, namely the reasons that will lead us to give a prominent role to the body proper and the environment in the constitution of the conscious mind, or even the reasons that will lead us to defend the thesis according to which we are embodied and situated, as well as the reasons that will lead us to reject the theoretical positions that dichotomize man and world. In order to support the thesis that we are embodied and situated, and therefore with the purpose of overcoming the theoretical paradigms that dichotomize consciousness and world, we will turn out to the authors and the perspectives we believe to be more successful in this endeavor, including the phenomenological approaches to bodily self-consciousness, the enactivists perspectives and the researches dedicated to mapping the interaction and integration relationships between brain, body and environment. To achieve our goals, the dissertation will be divided into two chapters: the first chapter will emphasize in what way the structuring of consciousness depends on the body proper and the environment, while in the second chapter we will resort to the phenomenological dimensions of bodily self-consciousness, emphasizing the bodily information channels that provide us the immediate certainty, in a first person perspective, that the self is bodily in a non-metaphorical sense.

A busca por uma política nacional dos biocombustíveis como tutela do direito fundamental ao meio ambiente : acautelamento e avaliação de riscos

The work is to demonstrate the scope of modern-day major regulatory provisions and the policies implemented to adoption of biofuels in the national energy matrix. The adoption of biofuels as an alternative to fossil fuels, is based on the realization of the fundamental right to an ecologically balanced environment mitigating hazards and environmental hazards arising from a postmodern society. However, the change in the Brazilian energy matrix observe the precepts of certain environmental principles to essentially environmental preservation The proposed Environmental rule of law is founded on the realization of the right (duty) key to an ecologically balanced environment for sustainable development. Thus, it is up to the State, in addition to considering the dangers and risks fruits of government decisions, present the possible instruments to mitigate the irreversible environmental damage to the environment. The management of environmental risks present in the ideals of an Environmental rule of law, plays an important role in the preservation and economic development, using, therefore, of acautelatórios legal instruments, such as environmental licensing and the ecological-economic zoning, measures adopted in the light of the principles of precaution and preservation. The adoption of research in the environmental field, improvement and development of environmental technology, building a system to observe ecological changes, imposition of environmental policy objectives to be achieved in the medium and long term and systematization of organizations plan a protection policy environmental, are essential measures to control possible environmental risks and damage guided by the aforementioned environmental principles. Thus, it will be used the inductive method of approach, starting from the analysis of the new perspective of Environmental rule of law and the implementation of biofuels in the context of a post-modern society, marked by uncertainty and the risk of damage, from the study of the principles of caution, maintaining and cautionary measures in mitigating the hazards and potential risks.

Contaminação ambiental e exploração capitalista ao meio ambiente: os resíduos sólidos na sociedade global

O mundo atual passa por uma crise ambiental sem precedentes na história, o que resulta em conseqüências ambientais perceptíveis e preocupantes. Governos e organizações internacionais têm dado maior relevância à variável ambiental como um dos principais eixos de definição das políticas de crescimento/desenvolvimento econômico, como o intuito de adequar as demandas sociais aos limites naturais. Como consequências dessa forma perdulária de produção e consumo da sociedade global temos a contaminação ambiental ampliada e diversificada. O presente artigo discute a acumulação capitalista no setor dos resíduos sólidos, partindo da hipótese da impossibilidade de se diminuir a geração ampliada dos resíduos, sendo necessário que se crie estratégias de gestão e tratamento para os resíduos baseados na atividade da reciclagem dos materiais. A parte final expõe os paradigmas da questão dos resíduos sólidos na sociedade global.

Espaços especiais em Natal (moradia e meio ambiente): um necessário diálogo entre direitos e espaços na perspectiva de proteção aos direitos fundamentais na cidade contemporânea

Some protected special spaces on behalf of fundamental rights to the environment and the housing at the city of Natal are fragile by facing actions and attempts to suppress and changing (or omission in the implementation) of standards in furtherance of those rights at the local level, which seems to reflect a situation that goes beyond the context of the city. Based on integrated approach of the housing rights and the environment and its protection of special spaces on the field of fundamental rights, the thesis seeks to understand the weaknesses that affect the legal state duty under the realization/implementation of fundamental rights to the environment and housing in cities, focusing on the issues of flexibility of the founding legislation of special spaces to the detriment of the attributes they protected and the lack of implementation of the legal system that allows their effectiveness. So, it looks initially to understand the environment and housing rights and their special protected areas in the brazilian legal system, looking forward the evolution of its legal protection, as well as the weaknesses that emerge in the field of their effectiveness. Analyzing the trajectory of the environment and housing rights and their special protected areas in Natal, considering its standards, attributes, protection indicators, weaknesses and negative evidence within its legal protections and their enforcement by state entity, this thesis proposes to verify the existence of forms to confronting the weaknesses founded in the maintenance of legal protection and its implementation. At this point it discusses the legal basis and safeguard instruments of protection, especially within the juridical field, as part of a (re)discussion about issues of legislative and administrative discretion in the face of objective legal state duty to realization/implementation of fundamental rights in the urban space. With all these issues together the thesis does not ignore the scenario where the dividing line between public and private (economic) are becoming ever more tenuous in the field of state action and where the city stands as a special commodity to the reproduction of real estate, according to the interests of capitalist logic

Meio ambiente e planejamento: a relação cidade-natureza nos Planos Urbanísticos da cidade de Natal no século XX

This research studies the relation between city and nature in the urbanity s plans from Natal RN, Brazil, during the 20th century. Investigates and analyses the main documents that bring environmental s ideas inside from the urbanity s plans of Natal; gives the historical and economical situation from the city in each period studied; features the urbanity s plans, using categories of analyses to comprehension of this instruments. Try to contribute in the bigger process of historical rescue of Natal, and stimulates new studies. It was used documental s research, and bibliographic material. It was identified four (04) kinds of plans: the ones that focus in health and aesthetic (1901, 1929, 1935) technology and science (1968), zoning and control (1974, 1984) and environment. The hints founded shows that environmental ideas were put inside of the plans by government demands, especially in 1994 s plan, almost always without popular contribution and without this population get understands its meanings and implications

Moradia e meio ambiente: extensão universitária e compromisso social

This book’s guideline is a description of the activities developed during the University Extension project entitled "Housing and Environment: building dialogue over the urbanization of the settlement Ilha", located in the Metropolitan Region of Curitiba. This project was coordinated by professors from the Federal University of Technology - Paraná (UTFPR). The initial objectives of the extension project were to investigate ways of intervention on the scenario of poor conditions of housing and urbanization of the settlement Ilha, for their land regularization. The book tells the story of the extension project, showing how the initial goals have changed with time. In addition, this book describes the frustrations and the learning process along the way, from the view of professors and students of UTFPR who actively participated in this project. This book also intends to report the feelings that the villagers attributed to their place of residence; the joys, stumbling and learning by using a participatory methodology from what Paulo Freire says about popular education. Moreover, the book brings the confrontation between the technical and popular vision on the regularization of the area.

Análise do licenciamento ambiental como instrumento de política do meio ambiente no Rio Grande do Norte Período 1992-2003

This analysis on the ambient licensing is based on a research that identifies the fragilities and advances of the application of this instrument of politics of the environment in the ambient politics of the Rio Grande do Norte, in the period of 1992 the 2003. The isolated urban area of Búzios, situated in the City of Nísia Floresta/RN, situated in the eastern coast of the State, where concentrates the boarding of the ambient question as a matter in the Brazilian process of urbanization, over all the institutionalization and implementation of the ambient licensing. They are distinguished in the used methodology in consultation to the diverse involved social segments with the ambient subject in study, the example of the managers, technician and specialists, as well as the application of the legislation and norms techniques, the forms of appropriation of the common wealth and the procedures of ambient licensing of the competent agencies. The results of the research designate that the ambient licensing while instrument of the ambient politics is one of the alternatives more efficient as techniques in the process of sustainable development, since it is beyond the prerogatives to conciliate the activities and enterprises with the conservation of the environmental resources and natural benefits to the societies. In the RN one evidenced progress in the ambient legislation and the instructions techniques, and that the imperfections and limitations in the system of ambient licensing are not directly on to the instruments, but in the implementation of mechanisms of the ambient agencies. This because they do not make use of operational structure to apply in practical and established abilities, as an ambient management, institutional joint and deliberations of the State Counselor for Environment
