Economia solidária e relações de gênero na agricultura familiar: o caso do grupo produtivo mulheres decididas a vencer

The Women s experiences in the private sphere under the work s field changes the family relationship allowing them more freedom, autonomy and independence. The inequalities, socially built, homemade women s obligations results in discrimination, difficult to insert and recovery on female s job in a job s market, including low salary if compared with men s and difficult to services access in addiction a difficult daily life and in domestic sphere. The women s organisation in productive groups or economically solidary enterprises (ESE) torn possible the social economically organisations and politicians to promote deep changes in a domestically e socially relationship, positioning, for example, women s in publics areas and in the rout of emancipation. The objective of this search are understand men and women relationship in the family agriculture s field starts insert women in economically solidary enterprises (ESE) on Mulunguzinho s settlement (Mossoró/RN). The theoretical framework is inspirited Economical Solidary concept kind division s job and women s empowerment. This search had a qualitative character and exploration through case s study on Mulheres decididas a vencer s group.

This finding confirm a different aspect not economical in solidary economy overcoming the monetary value in associative relationship observing principally individuals well-being and the concern with the form of reproduction this way of life in the associated

Visitabilidade-vivenciabilidade em assentamentos informais : um estudo da acessibilidade de percursos urbanos no Conjunto Santa Terezinha em Fortaleza-CE

This research approaches the issue of accessibility in informal settlements, seeking for the challenges and limits defined by informal urban settings, about the application of accessibility parameters. Take the empirical universe as the Conjunto Santa Terezinha, located in Fortaleza- Ce. Initially, the study presents a reflection about the housing issue in Brazil and the informal settlementes in view of the Right to the City. In this sense, the main references are, the works of Suzanne Pasternak (2008), Nabil Bonduki (1998) and Erminia Maricato (1996-97), among others. Follows with the discussion of the concepts and classifications of this type of settlement, making a content analysis of legislation and regulations relating to accessibility and proposed the discussion of the accessible route as the right strategy for the city. In another step, the methodology of 'walking together' created by Dischinger (2000) was applied in a passage previously chosen, which the researcher follows the disabled person during the journey through city making records like photos and video. The comments and perceptions are compared to the spatial analysis of urban morphology, made from the method of Del Rio (1990) and Panerai (2006), and the parameters of NBR 9050. Knowledge of the area is enriched by the methodology of the production of space made by Henri Lefebvre in his book 'The production of space' (1974) with these categories: space conceived, perceived and lived. Another key reference of this author it s the book 'The Right to the City' (991), which allowed in-depth reflections on the social function of town. In conclusion, the study finds that to guarantee a minimum access conditions in informal sittlements it´s necessary to know the specifics of their morphology, their relations and urban practices in view of the visitability- experiencebility, describing it as complementary concepts

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.

Incorporação de resíduos cerâmicos vidrados em argamassas bastardas: estudo de propriedades físicas e mecânicas

Dissertação de Natureza Científica para obtenção do grau de Mestre em Engenharia Civil Perfil de Edificações

Medidas de concentração de radônio proveniente de argamassas de cimento portland, gesso e fosfogesso

Portland cement being very common construction material has in its composition the natural gypsum. To decrease the costs of manufacturing, the cement industry is substituting the gypsum in its composition by small quantities of phosphogypsum, which is the residue generated by the production of fertilizers and consists essentially of calcium dihydrate and some impurities, such as fluoride, metals in general, and radionuclides. Currently, tons of phosphogypsum are stored in the open air near the fertilizer industries, causing contamination of the environment. The 226 Ra present in these materials, when undergoes radioactive decay, produces the 222Rn gas. This radioactive gas, when inhaled together with its decay products deposited in the lungs, produces the exposure to radiation and can be a potential cause of lung cancer. Thus, the objective of this study was to measure the concentration levels of 222Rn from cylindrical samples of Portland cement, gypsum and phosphogypsum mortar from the state of Paraná, as well as characterizer the material and estimate the radon concentration in an environment of hypothetical dwelling with walls covered by such materials. Experimental setup of 222Rn activity measurements was based on AlphaGUARD detector (Saphymo GmbH). The qualitative and quantitative analysis was performed by gamma spectrometry and EDXRF with Au and Ag targets tubes (AMPTEK), and Mo target (ARTAX) and mechanical testing with x- ray equipment (Gilardoni) and the mechanical press (EMIC). Obtained average values of radon activity from studied materials in the air of containers were of 854 ± 23 Bq/m3, 60,0 ± 7,2 Bq/m3 e 52,9 ± 5,4 Bq/m3 for Portland cement, gypsum and phosphogypsum mortar, respectively. These results extrapolated into the volume of hypothetical dwelling of 36 m3 with the walls covered by such materials were of 3366 ± 91 Bq/m3, 237 ± 28 Bq/m3 e 208 ± 21 Bq/m3for Portland cement, gypsum and phosphogypsum mortar, respectively. Considering the limit of 300 Bq/m3 established by the ICRP, it could be concluded that the use of Portland cement plaster in dwellings is not secure and requires some specific mitigation procedure. Using the results of gamma spectrometry there were calculated the values of radium equivalent activity concentrations (Raeq) for Portland cement, gypsum and phosphogypsum mortar, which were obtained equal to 78,2 ± 0,9 Bq/kg; 58,2 ± 0,9 Bq/kg e 68,2 ± 0,9 Bq/kg, respectively. All values of radium equivalent activity concentrations for studied samples are below the maximum level of 370 Bq/kg. The qualitative and quantitative analysis of EDXRF spectra obtained with studied mortar samples allowed to evaluate quantitate and the elements that constitute the material such as Ca, S, Fe, and others.

Argamassas de terra e cal - Características e campos de aplicação

As argamassas mistas de cal e terra devem ter resultado da prática profissional quando as condições económicas foram possibilitando a adição de cais aérea às argamassas vernaculares só de terra. Baixas adições de cal aérea a argamassas de terra têm conduzido a drásticas alterações da cor e das resistências mecânicas das argamassas de terra. No entanto, a substituição parcial de massa de cal por terra em argamassas de cal ao traço volumétrico 1:2 (correspondendo a argamassas com traço em massa de 1:8, com substituições de 10% a 50%) resulta em argamassas mais ecológicas e que tecnicamente indiciam ser adequadas para aplicação em rebocos de edifícios antigos e mesmo em construção nova com características compatíveis. Os resultados obtidos foram particularmente interessantes para uma substituição de 10% mas muito há ainda a fazer para um conhecimento aprofundado deste tipo de argamassas mistas de cal e terra, muito utilizadas no passado, com vista à otimização de formulações que possam vir a ser aplicadas correntemente.

Desenvolvimento de cerâmica vermelha utilizando rejeitos da construção civil

The Industry of the Civil Construction has been one of the sectors that most contribute to the pollution of the environment, due to the great amount of residues generated by the construction, demolition and the extraction of raw material. As a way of minimizing the environmental impacts generated by this industry, some governmental organizations have elaborated laws and measures about the disposal of residues from the building construction (CONAMA - resolution 307). This work has as objective the reutilization of residues compound of sand, concrete, cement, red bricks and blocks of cement and mortar for the production of red ceramic, with the objective of minimizing costs and environmental impacts. The investigated samples contained 0% to 50% of residues in weight, and they were sintered at temperatures of 950°C, 1000°C, 1050°C, 1100°C and 1150°C. After the sinterization, the samples were submitted to tests of absorption of water, linear retraction, resistance to bending, apparent porosity, specific density, XRD and SEM. Satisfactory results were obtained in all studied compositions, with the possible incorporation of up to 50% of residues in ceramic mass without great losses in the mechanical strength, giving better results to the incorporation of 30% of residues in the fabrication of ceramic parts, such as roofing tiles, bricks masonry and pierced bricks

Arquitetura da água - Cais palafítico da Carrasqueira

Permitindo uma forma de habitar lugares de grande relação com a água, erguem-se um pouco por todo o mundo, sobre as águas de rios, barragens e lagos estruturas palafíticas. Em Portugal, em 1964 na aldeia da Carrasqueira, extremo sul do estuário do Sado, um cais palafítico começava a ser construído por pescadores-agricultores, que ali viviam, para combater mudanças de maré e aceder tanto a água como a terra. O barco, o abrigo e o caminho são os três elementos fundamentais da arquitetura palafítica aqui encontrada, em que a qualidade da água e da terra são determinantes para o assentamento da estrutura neste local. O rio Sado define-se como o limite geográfico e paisagístico da ocupação, é gerador de características únicas que permitem o desenvolvimento de um novo tipo de habitar que surge sobretudo de uma aproximação ao local e aos materiais que dele provêm. A Carrasqueira traduz o paradigma de uma cultura em adaptação contínua às circunstâncias adversas do meio ambiente. A pouca informação sobre o cais e a unicidade construtiva encontrado na estrutura, faz com que seja de elevada pertinência o estudo, sob o ponto de vista construtivo, da arquitetura palafítica da vila piscatória da Carrasqueira, enquanto matéria mutável sensível às mudanças ambientais e espontâneas. Pretende-se clarificar e identificar as singularidades da arquitetura de expressão espontânea da Carrasqueira, intrinsecamente ligada tanto à água do rio Sado, como à terra que a limita e corporiza. Para o estudo construtivo serão elaborados:  Mapas de desenvolvimento do cais;  Um registo fotográfico das estruturas;  Desenhos, realizados originalmente no decorrer desta investigação no local, de forma a criar um maior entendimento da forma de construção entre as diferentes peças e partes de cada uma das estruturas.  Construção de uma estrutura palafítica.  Vídeo, enquanto registo das fases do trabalho prático mostra parte do trabalho desenvolvido no processo construtivo. A produção dos documentos mencionados testemunha um tipo de vida invulgar na História da Arquitetura Portuguesa. O contacto com locais, pescadores, trabalhadores e gentes da terra também ajudará a entender os sistemas construtivos utilizados, pelo conhecimento construtivo por experiência própria, e proximidade das matérias-primas; ABSTRACT: Allowing life in floodplain areas, palaffitic structures take advantage from water, and appear a bit all over the world. The stilts portray a way of living changing and giving identity to the places and population. In Portugal, 1964 year, in Carrasqueira village, located on the southwest Sado’s river, facing the river side and land, a palaffitic piers was built, to fight the tide changing and allowed the population to get as close as they could to water and reach the land easier when they were coming from the fishing activity. The continuously adaptation of lifestyle in order to follow and adjust themselves to nature shows how strong and unique this culture and people are. The boat, the shelter and the paths are the three fundamental elements used in Carrasqueira’s palaffitic architecture. Water and land, construction and nature, this beautiful balance is only possible because of the river and its qualities. Also the time roles an important paper in the process, it changes with the growing of the main materials. This investigation has the goal to study the palaffitic piers of Carrasqueira by the constructivist point of view, as a spontaneous structure that began with the available materials and was continuously changing and adjusting to fit the land, the lifestyle and the needs of the population that was living there. Clarifying and identifying the singularities of this construction is what the study wants to achieve. Maps, photography’s and intensive drawings will be making on the process. A palaffitic structure will be build and the part of the building process will be available for watch on a short-video, filmed by then. The contact with locals will probably assume the biggest part of the work in main to understand their way of thinking and the process of their work.

Aproveitamento de resíduos minerais na formulação de argamassas para a construção civil

Current environmental concerns include the excessive consumption and inefficient use of non-renewable natural resources. The construction industry is considered one of the largest consumers of natural raw materials, significantly contributing to the environmental degradation of the planet. The use of calcareous quarry (RPPC) and porcelain tile polishing residues (RPP) as partial replacements of the cement in mortars is an interesting alternative to minimize the exploration of considerably large amounts of natural resources. The present study aimed at investigating the properties of fresh and hardened mortars produced using residues to replace cement. The residues used were fully characterized to determine their specific mass, unitary mass, particle size distribution and morphology, and composition. The performance of the mortars was compared to that of reference compositions, prepared without residues. A total of 18 compositions were prepared, 16 using residues and 2 reference ones. The mortars were prepared using Portland CP II F 32 cement, CH I hydrated lime, river sand and tap water. The compositions of the mortars were 1:1:6 and 1:0.5:4.5 (vol%), and water to cement ratios of 1.87 and 1.45 were used, respectively. The mortars in the fresh state were evaluated by consistency index, water retention, density of mass and incorporated air content tests. In their hardened state, the mortars were evaluated by apparent mass density, modulus of elasticity, flexural tensile strength, compressive strength and water absorption by capillarity. The mortars were also analyzed by scanning electron microscopy, energy dispersive spectroscopy, X-ray diffraction and fluorescence. Finally, they were classified according to NBR 13281 standards. The mortars prepared using residues partially replacing the cement exhibited lower modulus of elasticity compared to the reference compositions, thus improving the performance in their intended use. On the downside, the water absorption by capillarity was affected by the presence of residues and both the tensile and compressive strength were reduced. However, from the overall standpoint, the replacement of cement by calcareous quarry or porcelain tile polishing residues did not result in significant changes in the properties of the mortars. Therefore, compositions containing these residues can be used in the construction industry

Construção participativa de SAFs em assentamentos.

O assentamento Sepé Tiaraju consiste no primeiro do estado de São Paulo criado pela modalidade de PDS (Projeto de Desenvolvimento Sustentável), por isso necessitando de um sistema de produção que alie a conservação ambiental, com o desenvolvimento, soberania alimentar e geração de renda às famílias assentadas. Atendendo a uma demanda do INCRA (Instituto Nacional de Colonização e Reforma Agrária) e principalmente dos agricultores assentados, a EMBRAPA ? Meio Ambiente (Empresa Brasileira de Pesquisa Agropecuária) vem desenvolvendo no assentamento um projeto que visa a apropriação por parte dos agricultores e a capacitação dos mesmos em SAFs (Sistemas Agroflorestais). No decorrer do projeto pode-se identificar que mesmo sensibilizados com o tema, os agricultores ainda tinham dificuldades em planejar seus SAFs, e atendendo a essa demanda dos agricultores foi realizado um curso para que os mesmos pudessem planejar suas áreas de SAFs. O resultado desse curso foram cinco implantações de SAFs em sistemas de mutirões participativos, que proporcionou uma rica troca de experiência entre os agricultores e técnicos presentes, pois os mesmos colaboravam em cada área a ser implantada, com seus conhecimentos ao mesmo tempo em que aprendiam com as experiências dos outros; resultando em um desenho diferente a cada implantação realizada, pois se levou em consideração os objetivos do agricultor que estava implantando o sistema, as características de cada lote, e o conhecimento de manejo do agricultor.

Diagnóstico participativo de práticas agroflorestais em lote de reforma agrária.

Sendo o assentamento Sepé Tiaraju o primeiro na modalidade de projeto de desenvolvimento sustentável, que visa conciliar a produção agrícola com a conservação ambiental e a geração de renda das famílias assentadas, o mesmo conta hoje com diversas experiências de agricultores experimentadores que incentivados por instituições governamentais e movimentos sociais vem se tornando referência no manejo e desenho de sistemas agroflorestais. Uma dessas experiências é relatada neste trabalho a partir de um processo de diagnóstico participativo entre técnicos do projeto EMBRAPA/INCRA e o proprietário do sítio "Paraíso Agroecológico", o Sr. Agnaldo Vicente de Lima.
