No imaginário feminino da Amazônia Paraense, migrar é um sonho, cujo conteúdo onírico faz parte não só de uma estratégia de sobrevivência, como também de uma busca por ressignificação dos lugares/construções/imaginário/ atribuídos ao feminino, na herança cultural sexista, racializada e heteronormativa imposta na e para a região. Muitas sonham viver em um contexto livre da violência; ter uma casa bonita, filhos saudáveis e um marido bondoso; outras sonham ganhar muito dinheiro trabalhando na prostituição, como dançarinas ou qualquer trabalho que possibilite a realizarão daquele ou de outros sonhos. Todas já escutaram estórias de outras bem sucedidas que migraram, e hoje possuem carro, roupas caras e uma casa para morar. Ouvem dizer, que há boas perspectivas em torno dos Grandes Projetos, mas não fazem ideia de como chegar, pois, muitos desses locais são de difícil acesso, como minas e garimpos. Já ouviram dizer que “no estrangeiro” sua exoticidade rende muito dinheiro. Outras, já ouviram estórias ruins de gente que foi escravizada, presa, deportada ou morta. Mas, apostam na sorte e acreditam que o risco vale a pena. Sabem o quanto é difícil sair do país, tirar passaporte, negociar em outra língua, outra moeda, lidar com uma burocracia complexa, exigente e uma legislação rígida e restritiva. Acreditam que se tentassem migrar sozinhas, sem o apoio de alguém com experiência no ramo, provavelmente não conseguiriam. Até que, aparece alguém se dizendo com experiência e com a oferta de providenciar tudo, com um simples toque da varinha de condão...O tráfico de pessoas, especialmente o feminino para fins de superexploração sexual - que inclui mulheres, travestis e transgêneros é uma violação de direitos humanos no contexto da migração. Terceira atividade ilícita mais lucrativa do planeta perde, segundo a Organização das Nações Unidas – ONU, apenas para o tráfico de drogas e o de armas. Possui natureza multifacetada marcada por uma dupla regulação: a capitalista e a identitária, cuja finalidade é sempre o trabalho escravo, incluindo o casamento servil e a prostituição forçada. Seu contexto extrapola a esfera criminal, perpassa por questões culturais e de gênero. Seu enfrentamento reclama o reconhecimento da diversidade democrática, do direito à não discriminação e dos parâmetros de direitos humanos.

A pesquisa teve como objetivo investigar a influência das ações efetivadas através do Projeto de Assentamento Agroextrativista no desenvolvimento local da ilha Tabatinga, localizada no município de Abaetetuba-PA. Para análise destas ações foram utilizados indicadores que possibilitaram verificar o nível de desenvolvimento local na comunidade a partir da implantação deste tipo de projeto. Ressaltou-se como elemento de análise os conhecimentos tradicionais presente na ilha Tabatinga, vinculado à pesca artesanal. Foi feita a caracterização do Projeto de Assentamento Agroextrativista, bem como a realização de uma análise da realidade da ilha Tabatinga, no que diz respeito ao modo de vida ribeirinho e por fim a realização da análise dos indicadores de desenvolvimento local a partir da implantação do PAE. No que diz respeito à metodologia o estudo teve um direcionamento qualitativo e quantitativo além de se ter utilizado a técnica de entrevista semiestruturada e da pesquisa participante. Os sujeitos da pesquisa foram os membros da ASPANLI (Associação PAE Nossa Senhora do Livramento), além dos assentados/pescadores, atuantes na realidade investigada. Os dados qualitativos foram analisados através da técnica de análise do discurso. Utilizando o método de análise temática, e, para que esses encaminhamentos fossem possíveis, fez-se necessário, primeiramente, a transcrição integral das entrevistas realizadas em campo e, por fim, os agrupamentos de dados de acordo com as categorias. Nesse cerne, os dados levantados com base nas análises de materiais coletados constataram que as ações relativas às atividades do PAE têm influenciado, parcialmente, no desenvolvimento local da ilha Tabatinga. A partir das análises conclusivas, apresentamos algumas sugestões que visam contribuir com a organização social dos moradores, sugerindo, dentre outras coisas, a criação de uma cooperativa de pescadores.

Melanin is a very important pigment to human species, and besides defining skin, eyes and hair color, it is also involved in sun exposure protection. This pigment is classified into two subtypes: pheomelanin, which is responsible for lighter pigmentation and eumelanin, the dark pigment related. Due to this type of melanin variation it is possible to found different phenotypes of hair and skin color. The genetics MC1R variations are described as the most important for diversity in pigmentation, and this gene is directly related to the complex process of melanin synthesis. The use of these variations to phenotype prediction using genetic information has been used in Europe countries to infer physical features from biological samples, with the purpose of directing searches of criminal suspects and victims identification. The aim of this study was to analyze 8 major MC1R polymorphisms in a sample of Brazilian individuals. Analyzing 91 individuals, we observed with higher frequencies the polymorphisms rs1805005:G>T, rs2228479:G>A and rs885479:G>A, which are related to skin and hair colors, as previously showed in literature. These data suggest the possibility of predicting phenotype from genetic polymorphisms in Brazilian population. However it will be necessary to analyze a larger number of individuals to be able to confirm these associations and to perform a more detailed statistical analysis

Brazil has about 12 % of a life´s essential resource: the superficial fresh water of the planet. However, today it is possible to observe the bad management of this resource, generating serious consequences on the quality that results in the loss of the use´s availability. In this scenario, the catchment of rainwater for undrinkable use is an alternative that has been broadly studied for the scientific community. When planning a system of rainwater catchment, the sizing of the required volume of the tank that will keep the water has a fundamental importance for the project, seeing that the supersizing of the tank can bring high costs and the undersizing can bring shortage in the water supply. This paper used a methodology based on two concepts: the harvesting efficiencies and the attending efficiencies of the system. This method takes as principle that exist a perfect demand that minimize the repayment time, condition that happened when the efficiencies are equal. Brazilian’s cities with different weathers and different rainfalls where chosen to simulate the attending for different demands for a typical residence. The data where parameterized according to the roof area and the number of residents, that way is possible that a future conference can be easily done and it also ensure results closer to the reality. The results showed that cities with a lower period of drought, even those with high level of rainfall on the raining mouths, have lower potential of water supply. The cities where the rainfall is more constant and also more high, even small roofs areas and small tank´s volumes – about half of the size compare to the cities with less propitious conditions – can generate high levels of water saving. With an eye to promote the environmental sustainability, the investment on projects for the catchment of rainwater is a good alternative

This conclusion thesis has the objective of produce substrates of Silicon Carbide from the powder of SiC for aerospace use. The powder of SiC was pressed in cylindrical form by the process called “wet way”. For the inicial pressing process was used a uniaxial squeezer and after that was used a isostatic squeezer, after that the samples were synthesized. The next step was the machining and polishing to improve the features of the surface of the sample. Then the roughness was measured, as also the Arquimedes method and optical microscopy and scanning eletron microscopy. Some innovations were done, in one of the lots little vacancys were done with organic material or silicon to reduce the weight of the sample; and the other innovation were the use of a slip film of SiC on the surface of the sample, that were after synthesized with LASER to reduce the roughness, in this samples the roughness were reduce in 50 % if compared with the other samples

This work presents the results obtained in analyzes of aggregates from construction and demolition waste produced by the plant of the City of Guaratinguetá. Using this data and comparing with the specifications of NBR 15115, it was found that the materials do not possess the requisite minimum characteristics to be utilized as a basis for low-pavement traffic. In order to identify the main reasons of the material does not fit in the standard, we used the data obtained in a study conducted by Professor. Dr. Luiz Eduardo de Oliveira at the plant of the company AB Environmental Solutions Ltd., located in Pindamonhangaba. With different characteristics, the aggregates from construction and demolition waste produced by this plant showed the possibility of using pavements. The use of these residues in paving reduces the impact on the environment caused by construction.

This paper aimed to study the treatability of rainwater collected in Rio Claro, SP, using natural coagulant tannin based. The tannin was compared with other too primary coagulants, namely ferric chloride and corn starch. Assays were performed in laboratory scale using equipment known as Jarteste and aimed to study the conditions most suitable dosage and coagulation pH. First tests were conducted to compare the coagulating and determination of the conditions to be used in the following tests, taking as a criterion the greatest efficiency for water treatment. Also performed were performed tests to construct the tannin coagulation diagram, using the optimal concentration found in the previous phase, by varying the dosage of coagulant and the pH of clotting in order to determine the isoefficiency regions for apparent color and turbidity. Finally, tests were performed cyclically filtration with filter paper. Preliminary tests indicated that the vegetable tannin concentration 3% (m/m) from the commercial solution was presented the best set of results (84.3% removal of apparent color and 82.51% removal of turbidity) compared to ferric chloride (66.25% removal efficiency and apparent color of turbidity 67.82%) and starch (73.68% removal efficiency apparent color and turbidity to 67.19%). The coagulation diagrams indicate that the best region to work with vegetable tannin 3% is where the coagulant dosage ranges from 15 mg/L to about 37.5 mg/L and coagulation pH ranging from about 6.5 to 7.5. The cyclic filtration showed to be not efficient for the best dosage of coagulant, due to the process of clogging of the filter paper, but proved to be efficient for other dosages. Thus, for the waters studied, the results indicate that the natural coagulant based tannin is an alternative to conventional coagulants, possessing benefits of technical and environmental

The aim of the present work is to investigate a simplified rainwater treatment strategy for nonpotable use. For this, there were simulated in laboratory scale the treatment conditions of a system that employs Corn Starch as a coagulant in cyclic filtration (from 1 to 5 filtration cycles). A commercial Corn Starch in different dosages was used (0,1; 0,2; 0,4; 0,6; 0,8; 1,0; 1,5; 2,0; 2,5; 3,0; 3,5; 4,0; 4,5; 5,0; 5,5; 6,0; 6,5; 7,0; 7,5; 8,0; 8,5 e 9,0 mg/L). The NBR 15527/07 recommended parameters were monitored on the inflow and outflow and compared to different first flushes (0.5; 1.0 and 1.5mm). The obtained results indicate that the 6.0mg/L dosage presented the best results (removal efficiency of 86% of turbidity; 88% of apparent color and absent of total and faecal coliform residuals). However, it was not possible to prove the filtration cycles benefit, in laboratory scale, because for some Corn Starch dosages the water did not present better quality when increasing the number of cycles.
