From the conduct of research and empirical literature analyzing the past tense trigger activity in the World Cassava and Agreste Potiguar, asserting that such activity has had a major role in subsistence farming in the training process agrestino planning, presenting, therefore, important for the survival of most agrestinos. After conducting a literature search and field survey, which was triggered, in a qualitative way, being on data and observations made in the agricultural space palntiu of cassava in the world and especially in the Agreste Potiguar and interviews with producers cassava, owners and workers in homes or industries flour that territory, we concluded that the modernization of agriculture in Brazil, propagator of elements called "new" is a process that cannot be regarded as synonymous with development, it generates and / or intensifies serious problems that cross historically and structurally the national society. This can also be said regarding the modernization of the activity in Cassava Potiguar Agreste.

With the increase of Brazilian economic growth and, consequently, the level of construction activity, the generation of residues from this sector is an important problem to be solved. Alternatives to recycle these residues, often in the composition of new materials, and developing models and management tools have been studied in several papers presented to the technical means in order to mitigate the effects caused by the impact of construction on the environment. However, the absence of public policies that consider the generation, handling and disposal of these wastes as a real problem, are still the biggest obstacle in the adoption of sustainable practices. This paper presents the general aspects of the management of waste generated by construction operations and demolition works to reform the Palestra Italia Arena (Allianz Parque) in the city of São Paulo by means of activities of recycling and reuse of these materials on the construction site of the works. The management of the demolition wastes produced in the construction work allowed significant economic gains, reducing transportation costs and acquisition of natural raw materials. The great part of the total amount of waste produced could be characterized as Class A.

This article is located on the border of the general debate of higher education policies. Such policies are linked to the strategies of integration of the economy in major changes worldwide. In this context, are established procedures for assessing higher education that contribute to the redefinition of the relationship between the state and higher education system. It is in this perspective that situates the subject of this study - to identify the model of public management that led to formal incorporation and final assessment as regulatory act and compulsory in the first Cardoso administration (1995-2002). Descriptive in nature, with a qualitative approach in the literature review highlight the characteristics of the Bureaucratic State and State Management. Also, we study the concept and meaning of efficiency in the administrative plan of both states. The results showed that the model of public management was in transition, when the policy called evaluation of higher education has become regulatory, permanent and compulsory in the country as having the same Model Management based on such achievement was only possible through bureaucratic actions anchored in excess legislation. We conclude that the emergence of higher education evaluation in the 90 expanded the bureaucracy.

This research intended to know how is made the process of environmental education in a school's context, supported by "Instituto Terra", located in the city of Aimorés, state of Minas Gerais, analyzing the possibilities of this pedagogical practice. Environmental education is a transversal theme that must be present in all subjects of High School and Elementary School, due to the situation that our environment is, mainly in the present days, beginning of XXI century. This subject became important because it provides the teachers support to work with the students about how to deal with environmental issues in a more participative, critical and conscious way, with the intention to slow down the destruction of our natural resources and protect more the nature, including the human being itself, and its quality of life. As a result of a research, this study propose to present the work developed by "Instituto Terra" with state schools in the city of Aimorés, as a successful case regarding environmental education, demonstrating that is possible to change a local natural reality with strong and present environmental teaching in school's context, in which the student is more dynamic, critic and participative in his behavior towards the environment.

This study objective to estimate the potential evapotranspiration and actual area of the municipalities belonging to the micro Seridó in the state of Rio Grande of the North, using the complementary model of Morton. After that we tried to spatialize the results to see how it distributes the ETR and ETP on the region. For the analysis it became clear that in regions where the first one is high the other tends to be low. It was seen that the ETR corresponded to low values in the central and high in the extreme north and south of micro Seridó as the ETP. Relating to the availability of energy concluded that during the year this variable was more important in the process of evaporation than precipitation on Seridó, making the model suitable for assessing when there low in precipitation.

This study was developed in the northern coast of the city of Macau, located in the State of Rio Grande do Norte. Characterized by contributions of oceanic water, flooding areas of swamps. Altogether, the climatic and topographical conditions provide an ideal environment for the development of saline activity. Inserted in the geologic context of the Potiguar Basin, the region presents favorable conditions for the production of hydro-carbons and natural conditions for shrimp breeding and artisanal fishing. This work analyzes the transformations occurred in the land use, using air photographs of 1978, Landsat 5 ETM Images of 1988, 1998 and 2008. A temporal analysis of the dynamics of the use of the territory and the changes in the landscape due to the development of productive activities. In the field it was observed that great areas used previously for the saline activity, today it is prepared for shrimp breeding and that the areas of petroleum exploration occupy salt mines, beaches and trays.

The Interest for work emerged of the discussions carried out in Art and education, discipline of Full Degree in Geography course offered by Instituto Federal de Educação, Ciência e Tecnologia do Rio Grande do Norte (IFRN), Campus Natal-Central, looking for through of the dialogue between the areas a pedagogical proposal, interdisciplinarity between geographic studies and the scenic spectacle of cabocolinhos. Understand such merriment as part of their ethnicity-representation of Brazilian society in view of the importance and the ethnic cultural contribution of indigenous to the brazilian space whose formation dance, as represented to an audience is as scenic presentation, being the focus of this article; in addition to being the first inhabitants of our land and by possessing a manifestation that represent some aspects of its culture in dance form in the municipality of Ceará Mirim, unique in the State. This study will be possible from the articulation of the geographer to the space of scenic spectacle, using an exploratory analysis that brings together literature revision regarding concepts used, as well as collecting primary data resulting from interviews and secondary data collection from documentary research. The work will provide strategies that will contribute to the understanding of the concepts and practices for future teachers.

The city of Natal is called by its inhabitants "Sun City" because of its high luminosity, however the capital of Rio Grande do Norte has rates of no melanoma skin cancer above the average of the capitals northeast of Brazil. In this scenario, article presents a study of the variability of Ultraviolet radiation (UV) and UV index for the city of Natal and its association with relevant variables as total ozone, aerosols, cloudiness and global solar radiation (RSG). The methodology conducted a descriptive study with statistical application of Principal Component Analysis (PCA) and Biplot graphic. The data were obtained from the National Institute of Spatial Research/Northeast Regional Center (INPE/CRN), instruments TOMS-OMI/AURA and MODIS/TERRA and National Institute of Meteorology of Brazil. The results indicated that the UV index has an annual mean of 11, rated as extreme by the World Health Organization and that intensity of UVB and UV index in the first half of the year are more intense than in the second. The annual variability of UV has a feature in the months of september and october that consisting of a stabilization/reduction of the UV index in a growth phase of RSG due to higher annual concentration of total ozone. The highest intensity of aerosols during this period contributes to this event. PCA and Biplot graphic contributed to identify the event, because indicated that total ozone and aerosols have a strong negative correlation with the UV index in those months. The authors called event with the abbreviation AES-UV (Annual Spring Event from UV) since it occurs at the beginning and during this season.

This paper aims to describe the development and results of the extension course "WHO LAUGHS LAST .... DO NOT KNOW THE CONTEXT", applied to state school teachers of Currais Novos city. The course aimed to encourage the implementation of reading and interpretation activities of humorous text types, namely - jokes, comics, caricatures and cartoons - so that, in their daily practice, teachers emphasize the importance of the factors of coherence, especially the knowledge of context, among their students. The course took as theoretical support the studies from Koch and Travaglia, about the factors that make possible establish the textual coherence.

Sea food is an important source of animal protein for the human population. Added to this importance, the aquatic food, especially the marine fish, contain compounds and properties that could help top event certain health problems. Moreover, the lean meat is recommended to avoid health problems and increase the people longevity. A negative aspect of the seafood is the high capacity of deterioration by physical, chemical and biological processes. Accordingly, the slaughter’s methods become important factors to be considered for a better preservation of food characteristics, since, during the slaughter process, the animal can shake off fairly making the energy reserves reduced drastically promoting the accumulation lactic acid, favoring the action of proteolytic enzymes and causing un wanted taste to the product. This review describes the mechanisms of slaughter, published in the literature, in different sea food species and the influence on final meat quality. Another important aspect described and analyzed, it was the wellness of the animal during the slaughter process.

Furthermore, the paper presents the evolution of the Assistive Technology concept and the relations that this concept has with information and communication technologies.

This paper aims to relate the discourse of human centered design (HCD) proposed in the literature of Klaus Krippendorff with the methods proposed by the IDEO company, and analyze which and how these methods have been employed in the brazilian design research through articles published in the last two editions of P&D congress. The research is a bibliographical study with comparative character, which is used the discourse analysis. Thus, it is possible to observe that HCD methods are more present in the beggining and intermediate stages of research, emphasizing the need for further development of such methods in the final stage of studies.

Researches about environmental perception are important for investigations of knowledge, values, beliefs, attitudes and expectations that people have about their place of residence, since every human being perceives, reacts and responds differently to the environment in which they live. In this sense, the present study aimed to analyze the environmental perception of the different social actors about the Abreu’s Lake in Formosa-GO. For this, we conducted semi-structured interviews with both locals and regulars to the place, and photographic records and observations held in place. The main problems identified by respondents were carelessness and neglect of the landscape, with the infrastructure, security, the environment and cleaning. These problems were constantly allocated to the Government as the main generator. In this perspective, it is expected that the government and residents commit to take care this important place of the municipality of Formosa-GO.

This paper discusses the knowledge of people who have built their lives in liaison and interaction with the sea. The knowledge of the Sea People are unique individuals who have knowledge of their grounded in practice with the water and the tide trajectory. The scientific and social relevance of this work is anchored in order to realize that the current education walks valuing the knowledge from the sciences, giving little credit to the common knowledge of such persons. In dialogs built with fishermen and shellfish and narratives of the individuals begin our study. The authors that make this work such as Freire (2005 ), Santos (2008 ) and Gohn (2010 ) discuss important aspects for understanding and reflection of the study. In the narratives of the actors and authors of the research realized that their knowledge are grounded in their culture, serving for the construction of their actions and practices. Fishing, shellfishing, live in the sea are some activities and behaviors that reinforce the identity of these individuals. We understand that the experience of life at sea is a decisive factor in the formation of populations of the sea. Commitments to life, participating in the work the research subjects, validate their knowledge as a web that leads its existence, and make them aware subjects in the world.

Objectifying to evaluate the interaction of a susceptible bean cultivar compared with no host bean cultivar stored in three atmospheric conditions: hermetic, semi-hermetic and no hermetic, about the development of weevil Callosobruchus maculatus (L.), conducted this research in the laboratory of Entomology of the UFC, in Crato-CE, on ambient conditions, during may to july of 2008. It was utilized a completely randomized design, with four replicates in a factorial 2 x 3, where the first factor referred to the cultivars of beans and as other factor, the three atmospheric conditions. At the eight days of infestation were evaluated the mortality of the adults and the egg-laying and, in the end of the storage period, evaluated the emergency of weevil and the loss of weight of the grains. The condition hermetic promotes higher mortality and lower emergency of the adults of weevil, along, lower loss of weight of the grains. Therefore, the hermetic control associated with susceptible cultivars of beans can be used as strategic alternatives for small growers to the use of chemical products in management programs of Callosobruchus maculatus in stored grains.

When we talk about quadratic equation, it is immediate to associate with the general formula erroneously attributed to Bhaskara in Brazil. This is due to overuse and often unique to this formula. The objective of this paper is to encourage and discuss the relevance and scope of other methods for solving quadratic equations that currently has been left aside by most Brazilian teachers, such as a geometric method present in "The Elements" of Euclid, the completion of squares (which demonstrate the general formula by geometric reasoning - adding areas) and the method of sum and product (which we will present in a device that extends its use for fractional roots).

The literature suggests that different models of productive networks according to their complexity, including supply chains, networks of cooperation, productive chains, local productive arrangements and clusters. The purpose of this article was to present a case in a cluster in which behaviors commonly reported in the literature about supply chain have been observed. Such behavior has emerged in a typical cluster environment that combines competition and cooperation (coopetition). We studied the relationships that were established between a leading company in the cluster, who went on to assume role similar to that of the focal firm in supply chain, and some of their suppliers, they have undertaken cooperative attitudes such as noted in the supply of raw materials in supply chains.

This paper presents a comparative analysis of HomePlug AV and 802.11n standards, addressing improvements to these standards with respect to its predecessors. Performance tests are standard in every home environment, considering parameter analyzed the transmission rate. The interest was to determine the relative performance of these technologies, considering the transmission rate depending on transmission distance, the size of packets and the number of active nodes in the network.

This article is evidence from the geographical studies conducted by analyzing the relationship space-culture. In Brazil, it is since 1990 that production begins to be evident. This study adds to this evidence since a little over two decades later it apprehends a significant part of these productions both in the national and international contexts so as to analyze the cultural dimension of space experienced by the “Araruna” group. The spatial representation of the reality experienced by the group performs in the form of monuments, a spatial form translated at the headquarters of the group, which comprises part of their culture and their identity.
