Cara e coroa: O PRONAF B e os impactos na ocupação rural do município de Ceará-Mirim

The present work deals with study on the National Program of Reinforcement of Familiar Agriculture, Group B, referring it offers of agricultural credit the agriculturists who possess familiar prescription until R$ 2,000, 00, and its impact in the agricultural occupation of the city of Ceará-Mirim. From theoretical referencial regarding the agricultural occupation, it collects of data, application of questionnaires between the beneficiaries of PRONAF B and interviews with the involved actors, it was made possible ascertainment of the hypothesis of that the program in this modality of credit, is capable to provide only to the maintenance or diversification of the occupation in the familiar unit and not it generation of remunerated occupation not familiar. This research disclosed to the diverse possibilities of use of the credit and its impact in the agricultural occupation, exactly when it is deviated for other purposes not waked up next to the financial institution, generating impacts not waited, however positive. When destined to the waked up end, still new forms appear of way occupation to complement it the deriving familiar prescription of the main activity. Unable to discard the rise even though very small and informal, non-family gainful occupation. The knowledge is added of that exactly ahead of the easinesses of access to the social base of the program, many familiar agriculturists still find difficulties in the approval of the which had credit, on the other hand, the requirements of the financial institutions

Variabilidade espacial da emissão de CO2, da temperatura e umidade de um latossolo desprovido de vegetação sob diferentes lâminas de molhamento

The irrigation application is one of the most useful techniques in tropical environments, especially during dry seasons. In this study, CO2 efflux, temperature and soil moisture were studied in a field sampled with a grid having 48 points distributed in 35 x 25 m, under irrigation promoted by a sprinkler located at the center of the area, provoking different levels of water deposition, with maximum irrigation levels of 44.4 and 62.2 mm in points closer to the sprinkler. The results show that the emissions, temperature and moisture were strongly affected by the two irrigations events, having a total water level added of 106,6 mm for the points next to the sprinkler and zero for the most distant points from it. The maps of space variation of the variables, as well as the linear correlation between them, indicate that the emissions were positively related to the soil moisture and negative correlated to the soil temperature only after the irrigations events. The special variability models of soil CO2 emission changed from exponential to spherical after the irrigations events. Such results indicate that soil moisture is among possible controlling factors of the soil CO2 emission, because even with reductions in soil temperature provoked by the wetness, emissions increased strongly.

"Reforma urbana já"; "arroz, feijão, saúde e habitação" :A luta por moradia na grande João Pessoa

Our object of study in this work concerns to the movement of fight for the housing in the Great João Pessoa, Paraíba, Brazil, and looks for to investigate the conditions and context of the occupations of building, public or private, for devoid populations that do not have where to live. Front to the absence of politics effective directed to the habitation or the cities, in a picture of unemployment and impoverishment of the population, the result of the habitation point of view, is the absolute lack of popular housings, the degradation of the cities and the growth of the number of homeless and also of its occupations. The urban occupations today represent a reply of these devoid populations that from an involvement with parties or Not Governmental Organizations, and social movements leave for the class action known by the occupation of abandoning public or private buildings. These occupations, even so initially if assume as pressure instrument or of visibility for attainment of housings, for the delay in obtaining the attention of the public agencies and a solution for the problem, becomes definitive or is drawn out per many years. E this if gives although the deficiencies, of the accumulation or families neither in an adequate, always precarious space nor in sanitary installations, that the necessary privacy does not allow. The study it consisted of an empirical research, through the participant comment and open and half-open interviews, and counted on the audiovisual register of two occupations, one in the downtown of João Pessoa City (old building of the INSS, in the Ponto dos Cem Réis) and other (Community of the Cajueiro), next to the Beach "Praia do Jacaré", in the city of Cabedelo.The choice of the Visual Anthropology as research instrument is on to a concern in better translating other ways of life, therefore the accomplishment of the video in allows them to know with more precision the reality where the citizens of the research live. We also use as methodological resource in the research the deepened interview, in intention to better understand the description of the way of life of the studied families and the movements of fight for the housing, particularly the MDM - Movement of Right for the Housing, and the MNLM- Nacional Movement of Fight for the Housing

Corpo e gestualidade :o jogo da capoeira e os jogos do conhecimento

In the direction of questing a sociology that considers the flesh dimension of the existence, that favors to think the body while place of the production of the knowledge, our itinerary of research is characterized for the reflection on the gesture of the body as power of life and production of knowledge, recognizing the precision of the gesture as a privileged breach of comment of the collective life, of the projection and registration of the culture, of the symbolic, of the sensitivity. Our problematic can be meet in the possibility to enhance an open and sensible rationality, tattooed in the body and accessible for the gestures, that its materialized in the relations of the human being with the other and the world, in singular and collective relations. Therefore, the gesture, constructed in the intention the experience of the body, can tell us about the human being, the society and the culture, therefore the sensed of the gestures is constructed from the established and recognized mutual actions for the citizens. It is in this field of production of the knowledge, of knowing of the meat that we direct our perception, in the challenge to immerge into the intention of the gesture in the capoeira game. Of the methodological point of view, for the analysis of the gestures of the capoeira, therefore, of the body as knowledge power, we consider registers of images as well as narratives registers of the universe of the capoeira, as well as my experience of more than seven years in the group of capoeira cordão de ouro1. A epistemological exercise has as support a qualitative research where parts of the quantity of images of the investigated group, as well as interviews, daily registers in of field and over all my experience of life next to the group and to the capoeira, in intention to recognize symbols tattooed in the body and for it produced in the inter subjectivists relations. We search therefore, to evidence sensible and meanings drawn for the gesture and evidenced by the look of the researcher. We presents as objectives of this inquiry to nuance ribbings around of the social and cultural elements in the production of the knowledge of the body, of the gesture, weaveeed for the sensible rationality

Incidência da varíola, causada por Asperisporium caricae, em folhas de mamoeiros submetidos ao manejo orgânico, em diferentes ambientes de cultivo

Mudas de mamoeiro da cultivar Baixinho de Santa Amália foram transplantadas para covas de 40x60x40 cm, em áreas de três estruturas contíguas: (a) estufa sombreada (cobertura de plástico), (b) estufa sombreada + sombrite (cobertura adicional de sombrite com 30% de sombreamento sobre o plástico) e (c) telado (cobertura exclusiva de sombrite 30%). Ao lado de tais estruturas foi implantada uma área de cultivo de mamoeiro em ambiente natural. Os tratos culturais aplicados foram os condizentes às normas técnicas vigentes na agricultura orgânica. As irrigações foram procedidas com mangueira plástica, evitando-se molhar folhas e frutos. Aos 45 dias pós-transplantio e, subseqüentemente, a intervalos mensais, as plantas foram inspecionadas em relação à incidência de lesões foliares causada pelo fungo Asperisporium caricae. Para efeito de análise estatística, após o teste de homogeneidade das variâncias, foram consideradas quatro repetições por ambiente (tratamento), com seis plantas úteis por parcela. O modelo de quantificação da doença indicou efeito altamente significativo dos ambientes protegidos, estufa e estufa sombreada, quanto à incidência de sintomas, em comparação com ambientes de telado e em área natural de cultivo. Durante os 12 meses de avaliações foi constatada alta correlação entre incidência da doença e pluviosidade e umidade relativa do ar. As estruturas cobertas com plástico demonstraram alto potencial de controle de A. caricae, sendo, portanto, recomendáveis no sistema orgânico de produção do mamoeiro.

Mestres e aprendiz: perambulando por ilhas de resistência

Monoculture of mind This idea, presented by Vandana Shiva, reflects the phase that we have experienced in the world: a notion of civilization that, since many decades, characterized by a technocratic big trend, has been shown as dominant and hegemonic. Based on a thinking and acting, felling and whishing standardization, this wave ends implying in what can be called of humanity‟s crisis at civilizational process. Destruction of simpler and more harmonious lifestyles with nature, human relations increasingly distant, values embrittlement, as respect, goodness and love, are some consequences of that behavioral homogenization. In the other hand, appears an archipelago of cultural and cognitive resistance against this devastating wave. Edgar Morin and Ceiça Almeida refer to this archipelago as a South Thought , what is not just a geographic question. Report, therefore, to some places, peoples, island that keep ancient costumes and knowledge, orally transmitted, for instance, from elders to younger, or vice versa, in an almost constant flow. Particular ways of experiencing the world around themselves, the men, animals, plants, rocks, or even not alive beings, masters or enchanted, spiritual guides. Next to a logic of sensitive, as Claude Levi-Strauss proposes, this reading, which is a more attentive, observer and wiser posture of surroundings, is based on touching, smelling, eating, seeing, and, I would add, felling. In light of this, I try to expatiate about certain experiences that I had the pleasure of living in some of these islands of resistance. Talks, perceptions, observations, sensations Stories, prose, poetries, music, photos, graphics Whatever could serve to portray even a bit of the reflections and forms to understand (ourselves) and produce knowledge, such as from a formation/Education to life, was well used at this ethnographic work. Space to the subjectivity and emotions I had, have, and will have a lot Everything for the dear reader may fell traveling around the world of tradition, resistance

Acompanhando o crescimento e o desenvolvimento da criança : uma intervenção integrada entre enfermagem e família

The accompanying the growth and development of the child is the guiding line of basic health measures directed at this public, acting within the scope of health monitoring and inferring positively in the rate of infant morbidity and mortality, which are still a preoccupation worldwide and in Brazil. However, mostly, this practice is based on the biomedical model of care, individualized, with emphasis on the medicalization and complaints, favoring the passivity of users. Given this issue, aim to develop accompanying the growth and development of the child in a Basic Unit Family Health, through a collective approach of medical care next to a health team, especially nurses and caregivers. This is a qualitative study, with the research-action method. Involved the four nurses and twenty-six of children's caregivers of the area of Basic Unit Family Health of Cidade Nova, in Natal, in the period from February to July 2010. The results were analyzed following the direction of the thematic analysis of Freire. In the situation analysis of the current reality of the accompanying the growth and development the children in the Basic Unit Family Health, through participant observation and applying a questionnaire to the nurses, we realize that despite these professionals have a knowledge tied to the paradigm of health promotion, in practice the monitoring of child is done through individual consultations in outpatient room, based on complaints brought by caregivers, with little solvability in actions employed. Given the need for change in medical care model, we decided jointly, in the focal group, for the collective monitoring of children's the growth and development, featuring then this proposal to the multidisciplinary team, discussing the participation of professional categories and planned collectively the actions. In the implementation stage of collective action, we contemplate the execution by the caregivers of anamnesis and physical examination, recording data in the Child Health Handbook and discussion of clinical findings, under the supervision of nurses and facilitators. In the evaluation, we found that this collective accompanying strategy allowed to caregivers learn new knowledge, exchange experiences, assistance in home care, beyond reduce the waiting time for medical care and creating opportunity of more time for debate about the children‟s health situation, differing of ambulatory care. As difficulties, we face with a high rate of defaulters (53.8%), lack of motivation and passivity of the users, little participation of other health professionals and nurses' involvement in other activities, technical and bureaucratic in the moment of care. Thus, we note also a strong rooting of individual clinical model on the way of thinking and acting of nurses and caregivers

Zona adensável de Ponta Negra em Natal/ RN: as conseqüências decorrentes da lei complementar 27/2000 na visão dos moradores da área

The quarrel on the urban intensific use of determined areas of the city is carried through in some levels of the society, which had to the fact to bring direct influences the population that inhabits it. The question to become an area to intensific use, implies in determining that the local infrastructure has the capacity to take care of to a bigger amount of people, inhabitants or passers-by. In the quarter of Ponta Negra, in Natal city (state of RN), its condition of area to intensific use to the municipal Law 27/2000 happened due that it starts to allow a bigger level of occupation of part of the quarter. This law has a direct relation with the installation of a complementary infrastructure in the quarter, to put does not send to its complementation and maintenance, what it takes the consequences that are felt by the population. This work has as main objective the identification of the decurrent significant consequences of the creation of Ponta Negra s Intensific Use Zone, according to vision of the population of the quarter. The way followed for this involves the compatible bibliography research with the subject, analysis of documents that treat on the quarter, mappings of the area in search of a physical characterization and mainly, an application of questionnaire next to local population. In this questionnaire it is the main point of the necessary collection of data to the work, indicating the point of view of the population not only on the negative points, but also on the positive points that had happened since the creation of Intensific Use Zone. The answers indicate problems of natures social, infrastructure and enviromental, compatible with the problems of other areas that had passed the same for process, as point the studied bibliography, indicating imperfections in the planning process and maintenance of Ponta Negra s Intensific Use Zone

Estudo da formulação de massas cerâmicas provenientes da região do Seridó-RN para fabricação de telhas

This work has for objective study compared the characteristics and technological properties of ceramic bodies from the region of Seridó-RN. The region under study has identified 23 cities where they were 80 ceramics industries. To define the universe of search, there was a survey of pottery that are part of APL Seridó next to the IEL. The characteristics and operating conditions of ceramics industries of the region were identified through a socio-economic questionnaire applied locally, which addressed issues such as: profiles of companies, production process etc. The analysis of information collected from 24 companies identified in seven cities shows that the vast majority of industries is small, with family structure, obsolete equipment and labo, little qualified. Most of the pottery works with low technical knowledge, poor control of the production process and product technology. The raw collected were submitted to analysis of X ray diffraction, chemical composition, termical analysis, particle size distribution and plasticity. Then were produced five formulations and made by uniaxial pressure at 25 MPa for firing in temperatures varying from 850 to 1050 °C. The firing technological properties evaluated were: mass loss to fire, lineal shrinkage, apparent density, apparent porosity, water absorption and flexural strength (3 points). The results indicated that the raw materials from the region have significant similarities in the composition chemical and mineralogical. Furthermore, it indicates the possibility of the use of cycles of firing faster and efficient than the current, limited to some clay mass burning of certain conditions

Adubação verde em pomar cítrico

A utilização de adubos verdes na citricultura ainda é pouco estudada, embora possa trazer benefícios ao citricultor, do ponto de vista econômico e de preservação dos recursos ambientais. O trabalho teve como objetivo avaliar a eficiência da utilização de adubos verdes em um pomar de laranjeira 'Pêra' enxertada em limoeiro 'Cravo'. Foram empregados quatro tratamentos correspondentes aos adubos verdes avaliados: feijão-de-porco (Canavalia ensiformis)), labe-labe (Dolichus lablab), feijão-guandu-anão (Cajanus cajan) e braquiária (Brachiaria brizantha - como testemunha). Os adubos verdes foram semeados nas entrelinhas da cultura e posteriormente foram roçados e direcionados para a linha na ocasião do pleno florescimento, 120 dias após a semeadura dos mesmos. O delineamento experimental foi em blocos ao acaso, com quatro tratamentos, seis repetições e duas plantas úteis para as avaliações. As características avaliadas foram: peso médio dos frutos, número de frutos por caixa de colheita (40,8 kg), produtividade, teores de matéria seca e de macro e micronutrientes contidos nos tratamentos, bem como rendimento de suco e ratio. Os resultados obtidos evidenciaram não haver diferença estatística entre os tratamentos para as características de produtividade das plantas e qualidade dos frutos. O feijão-guandu-anão apresentou o maior teor de matéria seca no primeiro ano de experimentação, diferindo estatisticamente dos demais tratamentos. No segundo ano, diferiu estatisticamente do feijão-de-porco e do labe-labe, produzindo maior quantidade de biomassa.

Variação da qualidade da água de chuva no início da precipitação

One of the most evident and actual concern, not only in the scientific means, but also of the public knowledge in general, is the lack problem of the potable water, that come increasing more each time, motivated mainly for the po llution of the sources, the bad use of the water and the increase of the population. In such a way, the necessity of looking for new water sources and the development of techniques to use sources minus explored is becoming even more important and urgent. T he rainwater comes being used since a long time like a supplying source, but, due the few knowledge of its characteristics, the generated preconception and the discrimination around its consumption and to the bad use of the technique of collection and stor age, it comes being little used, wasting consequently a significant parcel of this source. Trying to develop the knowing of some characteristics of the rainwater, the present work looks for to define the curve of variation of the quality of the rainwater i n three points with distinct characteristics of the city of Natal -RN, in the course of the precipitation, in some situations of time and space. For describe the curve of variation of the water s quality, some variables must be analyzed, and to be identifie d when they modify themselves in the endurance of rain, showing in which moment the purification of the water is more or less quickly. The pH, the Turbidity and the Electric Conductivity can be related with a big part of the physicist -chemistries variables found in the water and, like its analyses don't spend any material, they have easy access and measurement. The present work analyzes the curves of decline of these three variables, in three points with distinct characteristics in the city of Natal -RN, being these points: one next to the sea, another one in region with great buildings concentration and the last point in a less polluted area. For the studied region, it was during the five first millimeters of rain that occurs the biggest reduction of the exi sting impurities in the atmosphere, mainly between the first and the second millimeter, and after the five first millimeters the values of the variables stabilize. With exception of the University Campus, where initially the rainwater already has very good quality, the values of Turbidity and Electric Conductivity suffer a brusque reduction after the first millimeter of rain

A gestão da qualidade nos cursos de graduação a distância da UFRN/SEDIS : a percepção dos discentes

The management of water resources in the river basin level, as it defines the Law nº 9433/97, requires the effective knowledge of the processes of hydrological basin, resulting from studies based on consistent series of hydrological data that reflect the characteristics of the basin. In this context, the objective of this work was to develop the modeling of catchment basin of the river Jundiaí - RN and carry out the study of attenuation of a flood of the dam Tabatinga, by means of a monitoring project of hydrological data and climatology of the basin, with a view to promoting the development of research activities by applying methodologies unified and appropriate for the assessment of hydrological studies in the transition region of the semiarid and the forest zone on the coast of Rio Grande do Norte. For the study of the hydrological characteristics of the basin was conducted the automatic design of the basin of the river Jundiaí, with the aid of programs of geoprocessing, was adopted a hydrological model daily, the NRCS, which is a model determined and concentrated. For the use of this model was necessary to determine some parameters that are used in this model, as the Curve Number. Having in mind that this is the first study that is being conducted in the basin with the employment of this model, it was made sensitivity analysis of the results of this model from the adoption of different values of CN, situated within a range appropriate to the conditions of use, occupation and the nature of the soil of this basin. As the objective of this study was also developing a simulation model of the operation of the Tabatinga dam and with this flood control caused in the city of Macaíba, it was developed a mathematical model of fluid balance, developed to be used in Microsoft Excel. The simulation was conducted in two phases: the first step was promoted the water balance daily that allowed the analysis of the sensitivity of the model in relation to the volume of waiting, as well as the determination of the period of greatest discharges daily averages. From this point, it was assumed for the second stage, which was in the determination of the hydrograph of discharges effluent slots, that was determined by means of the fluid balance time, on the basis of the discharges effluents generated by a mathematical equation whose parameters were adjusted according to the hydrograph daily. Through the analyzes it was realized that the dam Tabatinga only has how to carry out the attenuation of floods through the regularization of the volume of waiting, with this there is a loss of approximately 56.5% on storage capacity of this dam, because for causing the attenuation effect of filled the shell of this dam has to remain more than 5m below the level of the sill, representing at least 50.582.927m3. The results obtained with the modeling represents a first step in the direction of improving the level of hydrological information about the behavior of the basins of the semiarid. In order to monitor quantitatively the hydrographic basin of the river Jundiaí will be necessary to install a rain gauge register, next to the Tabatinga dam and a pressure transducer, for regular measurements of flow in the reservoir of the dam. The climatological data will be collected in full automatic weather station installed in Agricultural School Jundiaí
