Curso de extensão em histórias e culturas indígenas

O presente trabalho aborda sobre a terceira edição do curso de extensão em histórias e culturas indígenas direcionado aos agentes de movimentos e pastorais sociais, professores de Educação Básica, pedagogos, diretores de escola (municipal, estadual e federal), com a finalidade de formar multiplicadores na qualificação para a abordagem das temáticas das culturas e histórias dos Povos Indígenas, visando a contribuir para a implementação qualificada da Lei 11.645/2008 e na inserção da temática indígena nos contextos de atuação dos diferentes agentes. O curso foi concebido a partir de uma demanda apresentada pelo Conselho Indigenista Missionário – Cimi, que ofertou apoio logístico para o mesmo. Fizemos uma primeira edição em 2016, uma segunda edição em 2017 e em Julho de 2018 realizamos a terceira edição do curso no Centro de Formação Vicente Cañas, em Luziânia (GO). Nessa edição contamos com 30 participantes de diferentes profissões e de todas as regiões do Brasil

O NASCIMENTO BIOLÓGICO DA CRIANÇA

O presente trabalho trata da fisiologia do nascimento e da adaptação da criança à vida extra-uterina, assim como de suas repercussões no crescimento e no desenvolvimento posterior. São discutidos os agravos de maior risco de repercussão para o crescimento e principalmente para o desenvolvimento neuromotor e psicológiCO7 quais sejam: duração da gravidez; tamanho do feto e tipo de parto; assistência ao recém-nascido; hipóxia perinatal; icterícia do recém-nascido.Concluindo, enfatiza a improtancia de um “bom começo” a partir de condições facilitadoras e adequadas ao nascimento para que o processo vital da criança possa atingir toda sua potencialidade

CARACTERIZAÇÃO DO CONSUMIDOR DE LEITE NA CIDADE DE BELA VISTA – GO

O presente trabalho teve como objetivo principal descrever o perfil socioeconômico do consumidor de leite da região. Buscou-se conhecer a opinião dos entrevistados em relação ao consumo de leite na escola e a frequência de compra do leite, quantidade, precificação, necessidades e desejos, bem como os fatores intervenientes e os perfilhamentos dos compradores de leite. Por meio de questionários, 200 indivíduos foram entrevistados. O estudo proporcionou um levantamento caracterização dos consumidores com a análise descritiva dos dados, sendo o conhecimento adquirido ficou equiparado à teoria, demostrando que o preço é um fator de grande importância para a tomada de decisão de compra totalizando quase 70% dos participantes. A faixa etária predominante dos consumidores está entre 30 e 40 anos, sendo, a parte masculina maior e o maior grupo de consumidores tem renda entre 2 e 3 salários mínimos. Os compradores do município de Bela Vista de Goiás, têm habito diversificado em relação ao total consumido, e 62,5% tem ou estão cursando o ensino médio e não possui filhos.Palavra-chave: Perfil do consumidor; consumo de leite; Comercialização de leite

Comparison of in vitro

Introduction:. It is well documented that many species from Passifloraceae family can provide edible and nutritious fruits while the leaves of cultivated plants are renewable and waste material. This biomass may be further used in various sectors, especially as a bioactive food additive and as source of innovative pharmaceuticals, cosmetics or feed additives. The biomaterials and green chemistry are new sectors bioeconomy according to the high-level horizontal strategies and bio-based industries in Europe. In recent years, attention has been paid to the biological activity and phytochemical profiles of extracts from different species of Passiflora. However, there is little comparative studies using the same procedures and techniques in the same laboratory conditions for study of plant material obtained from the similar greenhouse conditions. Objective: This study was focused on the examination of antioxidative activities of low concentrations of crude extracts from leaves of Passiflora incarnata L., Passiflora caerulea L., and Passiflora alata Curtis. Methods: The activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS) radical scavenging and ferric reducing antioxidant power (FRAP) methods. Results of study were supported by estimation of chemical composition with secondary metabolites profiling in extracts which were carried out previously for the same extracts from three Passiflora species. One-way ANOVA analysis revealed significant differences in the antioxidant activity of various concentrations of the extracts using the DPPH and ABTS radical models, and FRAP method. Results: Measurement of antioxidant capacity (expressed as trolox equivalent, TE) showed that the most active was extract of P. caerulea > P. alata > P. incarnata. Phytochemical analysis for extracts of P. caerulea and P. incarnata showed greater similarities in metabolites content than P. alata. However, comparative statistical analysis of antioxidant activity showed that despite this phytochemical similarities, extract from P. alata leaves had higher activities than extract from leaves P. incarnata. Antioxidant effect of extract from P. alata can be explain by terpenoids presented in this extract. In this work, there have been discussed activities against Acanthamoeba castellanii strain, antibacterial and antifungal activities against selected clinical microorganisms (Enterococcus faecalis, Escherichia coli, Staphylococcus aureus, and Candida albicans, Microsporum gypseum), and anti-leukemic activities tested in human acute lymphoblastic leukemia cell lines for this extracts, which have been described in previous authors’ publications. Conclusion: Our current and previous studies showed that the same crude extracts from leaves of P. alata, P. caerulea, P. incarnata exerted not only antioxidant potential in vitro but also few interesting properties such as antibacterial, antifungal, amoebostatic, amoebicidal activities, which indicate the possibility of using these extracts in both a healthy diet and natural cosmetics. Leaves of this species may become an interesting source of biomaterials which can exert health-promoting effects

Aplicação de emulsões na flotação de minerio de zinco.

Várias linhas de flotação de minérios oxidados de zinco já foram estudadas e, segundo a maioria dos pesquisadores, a flotação catiônica com altas concentrações de sulfeto de sódio, usando amina primária como coletor, tem sido a opção mais adequada para concentrar esses minérios. Nesse trabalho, investigou-se a aplicação de novos sistemas de reagentes para flotar o minério de zinco com willemita, em etapas de depressão de gangas, dispersão, sulfetização e flotação do zinco. Os testes de flotação, usando emulsão de amina com óleos vegetais e diesel, mostraram que a amina emulsificada apresentou um desempenho na flotação superior à amina não emulsificada, além de permitir uma redução significativa de sulfeto de sódio. Dos óleos vegetais estudados destacaram-se a mamona e o coco-babaçu, porém os resultados de recuperação foram inferiores ao óleo diesel.Several approaches to the flotation of oxidized zinc ores were already studied, and according to most of the researchers, the cationic flotation with high concentrations of sodium sulfide, using primary amine as collector, has been the most appropriate option to concentrate this type of ore. In this work, the application of innovative systems of reagents to float willemite was investigated, including the stages of gangue depression, dispersion, sulfidization and zinc flotation. The flotation tests using amine emulsion with vegetable oils and diesel oil showed that the amine emulsion yielded a better flotation performance than that of amine without emulsion, besides allowing a significant reduction of sodium sulfide dosage. Among the vegetable oils studied castor and babaçu coconut oils yielded reasonable results, despite not leading to the same zinc recovery levels achieved with diesel oil
