Análise do processo de internalização de propostas de educação ambiental em escolas de Ensino Médio no município de Acaraú-CE

To insert environmental education in the school is a very hard task, although the question has been largely discussed since some years ago. The main object of this research is limited to the way the contents of Environmental Education are inserted in school programs, as well as to assert that, as a law, it must be put in practice not only because it is obligatory, but because it is important to school programs, especially to Acaraú´s primary and secondary schools, having in view the importance of the natural resources in which schools are inserted and the development of ways to solve problems related to the quality of life of the dwellers of these places. It is important the study of the law 9795/99 on Environmental Education, passed on July 25th, 2005, by means of the decree no. 4.281, established in the Municipal Organic Law and other documents ruling the Environmental Education. Our purpose is to give orientation on Environmental Education to the above-mentioned schools aiming at the permanent formation about that subject, in order to constitute, in the future, a real net between school and community and to spread out concepts about sustainability. This way, poverty conditions should be faced as environmental problems, bringing about the relationship between natural resources and poverty. The making of shrimp beds, predatory fishing, swamp degradation and irregular occupation constitute elements to this research. The theoretic terms are based upon principles of Environmental Education, area sustainability and inter-disciplinarily and trans-disciplinarily in Environmental Sciences, which have been applied under the form of capacities and the presentation of documents, projects, maps, discussions and reflections about the mass social movements as a positive consequence of the implementation of this project

Proposta de zoneamento geoambiental do município do Crato/CE

The geo-environmental zoning is an important means to plan the management of the territory, once it is the result of integration of different elements of the physical environment. The Municipality of Crato has a diversity of geo-environmental systems due to its complex landscape, which characterization and delimitation will contribute to the most appropriate occupation and the fewer prejudicial to municipal area. This study, which was supported by geo-systemic theory, searched to reach the following objectives: to elaborate a proposal of geo-environmental zoning; to characterize identified and demarcated geo-environmental systems, including their potentiality and limitations of land use and human occupation; and to generate a database on digital maps through GIS Geographic Information System. Four geo-environmental systems were identified (Chapada do Araripe: plateau and hillside, Massif and residual crest, Sertão of peripheric southern depression and fluvial Plains) and ten geo-environmental subsystems (Eastern plateau covered by cerradão/cerrado, Western plateau covered by cerrado/carrasco, Northern-west hillside, central residual Massif, Northern Residual Massifs, Sertaneja depression dominated by sedimentary materials, Sertaneja depression dominated by embasement crystalline material; wet fluvial plains and dry fluvial plains). The identified system and subsystem are similar to those proposed by FUNCEME in spite of some changes due to the more detailed mapping

Para onde sopram os ventos :politicas públicas de turismo no grande Pirambu/Fortaleza/CE

PARA ONDE SOPRAM OS VENTOS , metaphor used to indicate turism public politicsway to the west zone of Fortaleza, against the direction where until now this public politics was targeted, to the east zone. This context, análise the public politics implemented in the Grande Pirambu, so like the processes of nonterritorialization and reterritorialization unchain by the program os settlement and indemnification of the Projeto Costa Oeste. Aim to learn the transformations that unroll in the studied área, based in proceding methodologic that privileged the interviews with many social actors resettled, indemnificators, intirenants, livers and fishmen. The public politics analyzes run to the Grande Pirambu infer that the same answer at trying of urbam requalification of the área, object of the new exigence pretender by the touristics activities developed in Fortaleza, wish to incorporate this área at the turistics dynamic of the city. However, the implementation of the Projeto Costa Oeste do not occuring in calm way, by opposite sence the beginning, the same has been propitiated polemics and discussions, stired up about public politics between the municipa and state power, to bring about injury in the public coffers, to the developing turismo f the city and, mainly to the living around Grande Pirambu, unquiet and sad with the buildings of the referring project that there is running for four years

A participação dos residentes no processo de produção do território turístico em Canoa Quebrada-CE

The work present entitled the participation of resident in the production process of the tourist territory in Canoa Quebrada/CE has as objective analyse of which form the site population participates of the manufacturing process and appropriation of the territory s tourist Canoa Quebrada CE , in period undestood between from 1980 to the present day. The theoretical variable about which rest this search is the concept the territory expressed in the manifested in the process deterritorialization that always appears in conjuction whith the reconstruction of territories, in other words, the process of repossession. The migratory movement of new residents acts in the new sociospatial configuration that location, form new territoriality and (de) territorializing in space turistificado reflected dialectically through the emergence of a new sociospatial setting consisting of forms and images expressed physically in place.Finish the job showing that the participation of resident native and nonnative in the production process of the tourist territory in Canoa Quebrada occurred unevenly characterized by dominance of a small group, who has control of the practice of this activity, thus appears that tourism can be tendentious, since a large portion of the population does not benefit from their results, having a exclusion with various impacts that directly affect the everyday social population

Praia de Ponta Negra: uma abordagem da paisagem costeira de 1970 a 2010, Natal/RN

With process urbanization process the Brazilian cities have been goin through, Natal/RN does not differ from the other ones, it has had a fast, inordinate and planned urbanization, but not applied, it has caused a high increase of social environmental problems. One of the worrying problems observed is the change in the coastal landscape, which has caused serious damage to the city‟s population, more specifically, of Ponta Negra beach neighborhood. For the geographical studies, the issue, concerning the occupation of the beaches that has been getting higher and higher in the last decades is extremely important because these, in addition to being used as homes in the new urban configuration, have incorporated new ways of environmental interference, without a simultaneous advance of knowledge which would be necessary for a more suitable and rational use of litoral spaces. Thus, the current assignment aimed to focus the coastal landscape of Ponta Negra Beach, in the city of Natal/RN, checking and analyzing the effects caused by anthropic and natural action, and the way it reflects in the quality of life of the resident, working population and of the frequenters as well as the landscape transformations in the area which is object of study, from 1970 through 2010. The methodology used followed to stages, the first concerned the theoretical work bibliographic surveying and composition; and second one the empirical work marking of the environmental characterization and application of the questionnaires. So, we can measure that Ponta Negra, is very susceptible to environmental changes, the ones caused by the natural dynamics of the beach, as well as the human actions (society) in this really fragile and mutable space, so it needs, a more profound systematic study about the coastal landscape. In order to reach a minimization of the change of the landscapes in the coastal zones there must be an integrated management of the environments, based on the planning of actions and territorial reordination of the occupations of these so important spaces, environmentally, as well as socioeconomically. Whereas, only this way, we will have a sustentable development and a suitable use of that space

Análise e monitoramento geoambiental da praia de Genipabu/RN

Issues concerning coastal regions, especially the beaches have sparked quite complex because studies are there that most people in the world has secured housing, mainly from the half of the last century, without concern for the natural dynamics of these environments, which have complex interactions of continental and oceanic, coastal responsible for changes in locations that can be perceived in a few years and sometimes even a few days or hours. The search took as main goal, analyze the Genipabu Beach, in the municipality of Extremoz/RN, fragile environment and rapid momentum, which has been occupied in a disorderly and unplanned. Carried out a beach monitoring through profiles beach environments: defined stages morphodynamics; realization of characterize hydrodynamic processes; identification of changes in the landscape. To this end, made necessary a survey from the bibliographic collection for theoretical and conceptual rationale. An empirical step for conducting the environmental characterization of hydrodynamics, leveling and topographic analysis of sediments (in laboratory), for observation of changes in features, influenced, and natural dynamics, anthropic action that increasingly comes taking the characteristics from the natural landscape. Underlines therefore the importance of academic studies in several areas in these environments, for setting up a coastal zoning giving public subsidies for managers for managing and planning the use and occupation of the coast in their areas

Monitoramento da dinâmica costeira da praia de Ponta Negra

This dissertation includes the monitoring of coastal environmental dynamics at three points distinct from Ponta Negra beach, located on the South Coast of Natal, capital of Rio Grande do Norte, in the period June 2012 to May, 2013. For this, the following hypotheses were developed: Which actors morphodynamic and/or anthropogenic responsible for the changes in the study area? And yet, the configuration of the morphodynamic state of the beach, dissipative, reflective or intermediate? Faced with these questions , studies on the beach environment has its relevance as they may clarify the risks and responsibilities of anthropogenic intervention and also assist managers in more targeted action regarding the protection of praiais systems, since once committed, it is very difficult recover the environmental framework of the area, being greatly more feasible the development of multidisciplinary work plans that can guide human actions possible in search of an understanding to the harmonious interaction between society and the beach system. Its main goal is the understanding of the processes of coastal dynamics, methodological procedures that supported the implementation of this research were based on the object of study related literature associated with the collection of data resulting from beach profiles made monthly in spring tides (full moon), the hydrodynamic data and statistical quantification data (%) and size classification of sediment sediment after laboratory analysis. The results obtained from annual comparative tables of beach profiles, associated sedimentological analysis, indicated a positive sediment budget, tending to equilibrium for Point 01 and Point 02 negative. Have to Step 03 were added to the hydrodynamic data, which allowed also on a comparative framework, the perception of a depositional dynamics, with a tendency to decrease the accumulation of material at the end of the annual cycle. These data also allowed for the point 03, the calculation of the volume of material transported by the longshore current was around 104.280 m³/m, plus the Dean parameter which established a morphological state of the dissipative beach with specific prevalences for point 03. Thus, given the results presented in this work in a timely monitoring of coastal dynamics is expected that managers and public authorities can articulate multidisciplinary work plans, always aiming actions that seek understanding and effective commitment to the recovery of the harmonious interaction between society and Ponta Negra beach environment

Zoneamento ambiental do Município de Aquiraz-CE

The Metropolitan Region of Fortaleza (RMF) is composed by thirteen cities, where is call the attention of Aquiraz. The city has a excellent resort area and a big importance in socioculture and historics aspects. It was one of the first village of Ceará, and it was founded in 1699, with was also the capital of the state until 1726. The urban local development has been disorganized in the last decades, the fact is, insert of turismon in its coast, and it is unable with alow capacity of the natural suppots, configuring unsustainable and et environment ambience. Considering as a turistic region, it is preoccupy, been necessart to create a better control of the nature of the region by the users. The environmental zoning in this work it is to plan of adequate form the use of the ground based in the management of the interests and the social and economic necessities in accord with the preservation of the environment and the natural characteristics of the city. The same is one great instrument planning where use to be analized in differents ways: social, ambiental, economical and institucional, and promove alternatives of use and occupation of the land to recreate the city. The methodo used to get the real objective, englobed zonal maps in ambiental unities and others themes (geologic/geomorphologic) since than the images from satelities LANDSAT and SPOT and fotografies under position of maps, secundaries listes gets in publics department, bibliographie, informations by the local populations. This prociduries mede easy to create maps, geologic/geomorphologic, of use and occupation the earth and the environmental zoning to analize the dynamic and the working of each ambiental unity of the city Aquiraz wich is located by map of this job. As a result of this job was confectionated the environmental zoning map of Aquiraz wich was divided in five ambiental unities and restrictions areas of occupation: unit I Littoral Plain (zoning with serious restrictions to the occupation); unit II Sub-Littoral Plain (improper zoning to the occupation); unit III between tray zoning Pré-Littoral and Peripheral Depression (improper zoning to the occupation); unit IV Strativism reserve of the plug (zoning used more under control in its occupation) and unit V Fluvial Plain Localities of the Indians Jenipapo-Kaninde/ locality Quilombolas (zoning used more without official regulation). With proposal in the ambient units above one expects that it has a reduction of the ambient degradation and protection of the local biodiversity of the city of Aquiraz in the State of the Ceará

Spectroscopy properties and energy level location of Gd(2)O(2)S:Pr(3+),Ce(3+)

In this work we propose the study of the spectroscopy properties and the energy level location of Ce(3+) and Pr(3+) in Gd(2)O(2)S, along with the effects of Ce(4+) (Ce(2)O(2)S(2)) incorporation in Gd(2)O(2)S and Gd(2)O(2)S: Pr(3+) in order to understand the formation and position of the associated defects energy levels in relation to the band structure of Gd(2)O(2)S and Pr(3+) energy levels. Ce-, Pr(3+)-doped and Pr(3+), Ce-doped Gd(2)O(2)S were prepared by the sulfidization of a basic gadolinium carbonate with S(8) using H(2)/N(2) (3.0/97.0%) and air during the firing of the precursor. Samples were analyzed by X-ray diffraction in order to guarantee the formation of the Gd(2)O(2)S single phase. Diffuse reflectance spectroscopy and luminescent measurements (emission/excitation) were used to locate Ce(3+), Pr(3+) and defects energy levels in relation to the band structure of Gd(2)O(2)S.

Determination of olive oil acidity by CE

In this work, a CE method for the determination of olive oil acidity was proposed. The method was based on an ethanolic extraction (at 60 degrees C) of the oil long-chain free fatty acids (LC-FFAs) components followed by CE determination in pH 6.86 phosphate buffer at 15 mmol/L concentration containing 4 mmol/L sodium dodecylbenzenesulfonate (SDBS), 10 mmol/L polyoxyethylene 23 lauryl ether (Brij 35((R))), 2% v/v 1-octanol and 45% v/v ACN under indirect UV detection at 224 nm. Although this electrolyte promoted baseline separation of myristic acid (C14:0) (internal standard (IS)) and olive oil major components (palmitic acid (C16:0), oleic acid (C18:1c) and linoleic acid (C18:2cc)) in less than 8 min, after a few injections, the electropherogram profiles were severely altered (peak broadening, migration time shifts, etc.) and the current increased substantially. An adsorption study was conducted revealing that the dissolution of the capillary external polyimide coating during the electrophoretic run caused the detrimental effect. After removal of the capillary tip coating, ten consecutive injections could be performed without any disturbances and this simple procedure was, therefore, implemented during quantitative purposes. The reliability of the proposed method was further investigated by the determination of acidity of an extra virgin olive oil sample in comparison to the established methodology (AOCS method Ca 5a40, alkaline volumetric titration (AVT)). No statistical differences were found within 95% confidence level. A % acidity of 0.39 +/- 0.02 was found for the olive oil sample under consideration.
