As amostras foram caracterizadas nos tempos 0, 30, 60 e 90 dias de armazenamento. Para o teor de fibra alimentar, foram encontrados valores de 10,5 (CL) a 11,8 (CR) g.100g-1, desta forma o produto pode ser considerado com alto teor de fibras. Quanto às características físicas e químicas, foi verificado para o tratamento de congelamento lento, no tempo 90 dias, um decréscimo significativo do valor de Chroma (C*), indicando uma menor intensidade da cor branca nas polpas de coco neste momento do tratamento. Em relação à firmeza, o decréscimo dos valores, durante o tempo de armazenamento, no congelamento rápido, foi menor que no congelamento lento. Na análise sensorial, as notas de cor variavam de 1 a 9, sendo 1 indicando amostra com coloração branca e 9 amostra com coloração amarelada. As médias obtidas (1,94 no CL e 1,89 no CR) demonstraram que não houve percepção por parte dos provadores da perda da cor branca até o final do armazenamento para os dois tratamentos. Os valores médios de notas obtidas de aroma foram baixos. Para os valores de sabor não houve efeito de tratamento (p=0,22), não houve efeito dos dias de armazenamento (p=0,94) e não houve efeito da interação tratamento versus dias de armazenamento (p=0,74).

abstract: ABSTRACT Objective: The purpose of this randomized, placebo-controlled trial was to investigate the effect a daily coconut oil supplement (2 grams) would have on a common serum marker of systemic inflammation (C-reactive protein) and an indicator of oxidative stress (TBARS) when compared to the control group receiving a placebo capsule (white flour) in healthy, sedentary adults between the ages of 18-40 in Phoenix, Arizona. Design: This study was designed as secondary analyses of blood samples originally collected to study the effects of coconut oil supplementation on blood lipids and body composition. The original study consisted of 32 healthy, adult volunteers recruited from the Arizona State University campus in Phoenix, Arizona. Participants followed no food restrictions or special diets, exercised less than 150 minutes per week, had no diagnoses of chronic disease, were not taking statin medications, were non-smokers, and no female participants were pregnant. Participants were randomized into either the Coconut Oil group (CO) or the Placebo group (PL) at week 0, and baseline blood samples and anthropometric measurements were obtained. Each participant completed an 8-week protocol consisting of two supplement capsules daily (coconut oil or placebo). Final fasting blood samples and anthropometric measurements were taken at week 8. This study analyzed the blood samples for measurements of C-reactive protein (CRP) and thiobarbituric reactive substance (TBARS). Results: Eight weeks of 2 grams per day coconut oil supplementation, in comparison to placebo treatment, did not significantly reduce serum CRP ( -13% and +51% respectively, p=0.183) but did significantly increase TBARS ( +16% and -27% respectively, p=0.049). Conclusions: Coconut oil supplementation (2 g/day) may impact lipid peroxidation as indicated by an increase in plasma TBARS concentration. Future trials are necessary to corroborate these results using other indices of fatty peroxide formation. / Dissertation/Thesis / Masters Thesis Nutrition 2017

Com esse intuito foi realizado um estágio junto a uma Unidade de beneficiamento e industrialização da fibra de coco, localizada na comunidade de Praia Grande, no município de Ponta de Pedras, Ilha do Marajó, no Estado do Pará. Nesse estágio foram coletados dados a respeito de todo o processo de beneficiamento da fibra de coco até a produção de mantas a base de fibra de coco com látex para aplicação em veículos. Através da Mercedes-Benz do Brasil, foram feitas amostragens dos materiais em estudo: fibra de coco, manta de fibra de coco com látex e espuma de poliuretano. É importante notar que a fibra de coco e suas mantas foram fornecidas pela Unidade de beneficiamento e industrialização de fibra de coco já citada e, a espuma de poliuretano foi fornecida pela Empresa Sanko de Diadema - SP. A partir dessas amostragens foram realizados ensaios de compressão e torção, apenas compressão, análise de metais e análise qualitativa do produtos formados na pirólise desses materiais, visando analisar assentos automobilísticos a base de fibra de coco com látex como um possível substituto da espuma de poliuretano. A partir deste estudo foi possível verificar que ambos os materiais sofrem deformação volumétrica após os ensaios de compressão e torção e, apresentam um comportamento de retorno ao seu volume inicial. No entanto, a espuma retorna praticamente 100% ao seu volume inicial enquanto a manta de fibra de coco com látex mantém uma deformação em torno de 10%. Quanto a análise qualitativa dos produtos formados na pirólise a 800oC desses materiais verificou-se que o fumo produzido pela pirólise da espuma de poliuretano é mais tóxico em relação ao produzido pela manta de fibra de coco com látex. / The aim of this work is to present a contribution to the analysis of the life cycle of vehicles' seats made with a mixture of coconut fibres with latex. Part of the work was developed at a unit for manufacture and industrialization of coconut fibres, at the community of Praia Grande, town of Ponta de Pedras, Marajó Isle, Pará, Brazil. At the unit, information on the processing of the coconut fibre was collected, ranging from the raw material to the production of a mat of natural fibre with latex to be used in vehicles. The different materials involved in the study were analysed at the laboratories of Mercedes-Benz do Brazil: coconut fibre, the mat of natural fibre with latex, and polyurethane foam. The polyurethane foam was supplied by Sanko, from Diadema/SP. Once obtained the samples, they were submitted to tests of compression and torsion, compression only, analysis of heavy metals content, and qualitative analysis of products resulting from the incineration of the different materials. The coconut fibre plus latex composite was evaluated as a possible substitute for polyurethane foam in seats. Starting from this study it was possible to verify that both materials suffer volumetric deformation after the compression rehearsals and torsion and, they present a return behaviour to its initial volume. However, the foam comes back 100% practically to its initial volume while the mat of coconut fibre with latex maintains a deformation around 10%. As the qualitative analysis of the products formed in the pyrolysis to 800oC of those materials was verified that the fume produced by the pyrolysis of the polyurethane foam is more toxicant in relation to the produced by the mat of coconut fibre with latex.

The Commercialization of agricultural products is characterized by some particularities as the high dependence of the climatic conditions, limited useful life of the agricultural products, seasonal in the consumption and in the production. This researches is based in the concept of productive chain with emphasis in his/her commercialization system, limiting to understand the process of commercialization of the production; or be the primary market of the green coconut. Some varied win prominence in this research how to understand the formation the price of the coconut, which the difficulties found in the commercialization process by the involved actors and which the main consuming markets of this product. This study has as main instrument of collection of data the questionnaire standardized that it was applied with the tied groups the commercialization (producers, transporters, distributing), seeking to describe the main characteristics of this segment. The problem it was treated through a qualitative approach. The field research was accomplished between September and October of 2010 and they were obtained the following results: Heads' of the family of the producing settlers' masculine sex, a majority prevalence works between 7 and 8 hours a day, the same ones are experienced in the cultivation of the coconut because 65% declared to work with the fruit has more than 10 years and 64% of them have income of to 3 minimum wages. The cultivation of the green coconut it is predominant in relation to the dry coconut because only 13% of the producers revealed not to work with green coconut. The cities of São Paulo, Brasília and Recife were configured as the main consuming markets. Practically formal contracts of commercialization don't exist. The section faces price seasonal, in the summer high prices and in the winter low prices. In relation to the main difficulties, the credit readiness was portrayed by 49% of the interviewees as of difficult access. In relation to local structure grocery stores and the access highways don't exist to the ranches were white of a lot of critics among the transporters. / Este estudo tem como objetivo principal analisar como é realizado o processo de comercialização do coco verde no perímetro irrigado de São Gonçalo – PB. A Comercialização de produtos agrícolas é caracterizada por algumas particularidades como a alta dependência das condições climáticas, vida útil limitada dos produtos agrícolas, sazonalidade no consumo e produção. Esta pesquisa fundamenta-se no conceito de cadeia produtiva com ênfase no seu sistema de comercialização, restringindo-se a entender o processo de comercialização da produção, ou seja, o mercado primário do coco verde. Algumas variáveis ganham destaque nesta pesquisa, como entender a formação do preço do coco, quais as dificuldades encontradas no processo de comercialização pelos atores envolvidos e quais os principais mercados consumidores deste produto. Este estudo tem como principal instrumento de coleta de dados, o questionário padronizado, que foi aplicado com os grupos ligados à comercialização (produtores, transportadores e atravessadores), visando descrever as principais características deste segmento. O problema foi tratado através de uma abordagem qualitativa. A pesquisa de campo foi realizada entre setembro e outubro de 2010 e foram obtidos os seguintes resultados: Predomínio de chefes de família do sexo masculino, a maioria dos colonos produtores trabalha entre 7 e 8 horas por dia, os mesmos são experientes no cultivo do coco, pois 65% declararam trabalhar com o fruto há mais de 10 anos e 64% deles tem renda de até 3 salários mínimos.O cultivo do coco verde é predominante em relação ao coco seco, pois apenas 13% dos produtores revelaram não trabalhar com coco verde. As cidades de São Paulo, Brasília e Recife configuraram-se como os principais mercados consumidores. Praticamente não existem contratos formais de comercialização. O setor enfrenta sazonalidade de preço, no verão preços altos e no inverno preços baixos. Em relação às principais dificuldades, a disponibilidade de crédito foi retratada por 49% dos entrevistados como de difícil acesso, na estrutura local não existem armazéns e as estradas de acesso aos sítios foram alvos de muitas críticas entre os transportadores.

Two batch mesocosms were created on site in Da Nang, Vietnam to reduce nutrients in wastewater from fish processing factories. The mesocosms contained either activated carbon or coconut fibre which in earlier studies has shown promising results in wastewater treatment. Three aspects of the materials were compared; Chemical content, which measured levels of COD, total-nitrogen and total-phosphorus. Rate of biofilm formation, where biofilm were measured visually and through weight. The last aspect was microbiological presence where fours species of microorganisms were cultivated. The experiment showed no obvious difference between the materials but concludes that this is an experiment that could and should be developed further.

Magister Philosophiae - MPhil / Post-apartheid South Africa has strived for change through the implementation of preferential procurement policy legislations such as the Black Economic Empowerment Act, Employment Equality Act, as well as the right to education for all has opened opportunities for many who were previously disadvantage. Being black in apartheid South Africa meant being middle class came with many constant difficulties of negotiating boundaries with community members that were not middle class and spaces that were middle class but white, thus raising several racial dynamics not experienced at ‘home.’ Being black in post-apartheid South Africa has also come with difficulties of constantly evolving social identity changes and categorisation.
