O setor pesqueiro tem grande importância em termos de geração de emprego e renda para a Amazônia, sendo a atividade de pesca comercial e de subsistência a maior fonte geradora de empregos do setor e a indústria pesqueira a grande fonte geradora de renda. Contudo, a indústria pesqueira na Amazônia apresenta diversas dificuldades em relação ao abastecimento de matéria-prima e treinamento da mão-deobra. A sazonalidade das espécies influencia o sistema produtivo das empresas que mantém seu quadro funcional variando devido a safra das espécies comerciais. Esta dinâmica do setor faz com que algumas empresas de pescado adotem sistemas rotativos, contratando funcionários na safra e demitindo-os na entressafra, enquanto que outras adotam o sistema de banco de horas, mantendo o quadro fixo de funcionários e compensando as horas trabalhadas a mais no período da safra por horas não trabalhadas no período da entressafra. Em razão desta sazonalidade, em geral, as empresas de pescado apresentam funcionários com baixa qualificação e com difícil adequação aos padrões de higiene. A instabilidade do emprego por outro lado, desestimula o funcionário ao treinamento. Manter o quadro fixo de empregados é política de algumas empresas. Essas apresentam menor desperdício de matéria-prima, maior rendimento do empregado, funcionários mais treinados e adaptados aos padrões de higiene exigidos. Contudo, a contratação de empregados permanentes exige que a empresa tenha uma estratégia mais ampla para o abastecimento de pescado na entressafra de forma que seja possível manter a mão-de-obra contratada nesse período.

A região de Vila do Conde é um importante pólo industrial no sul da baía de Marajó. Apesar da importância da pesca e da vulnerabilidade da região em relação ao impacto ambiental, não há nenhum estudo aprofundado sobre a pesca e a ictiofauna na área. Com o objetivo de descrever a atividade pesqueira na região, desembarques pesqueiros foram acompanhados na praia do Conde, de dezembro de 2005 a novembro de 2006. O índice de abundância relativa, captura por unidade de esforço (CPUE em kg/viagem), foi utilizado para identificar períodos, espécies e frotas mais relevantes da atividade pesqueira. Foram cadastradas 43 embarcações pesqueiras, sendo dominantes os barcos de pequeno porte. A principal arte de captura utilizada pela frota foi o espinhel. As principais espécies comerciais identificadas foram Brachyplatystoma rousseauxii (dourada), Plagioscion squamosissimus (pescada-branca), Pellona flavipinnis e P. castelnaeana (sarda) e B. filamentosum (filhote). As embarcações capturaram, em média, 19 kg/viagem. A produtividade entre as motorizadas foi superior ao registrado pelas não motorizadas. Foram observados dois picos de produção, em janeiro e em setembro/outubro. A receita bruta oriunda da comercialização do pescado ultrapassou os R$ 100.000,00, sendo os barcos de pequeno porte responsáveis por 36% da captura total.

This study has as objective determining the chemical properties that serve as the basis for potential scientific and technological applications of seven species of fibrous plants cultivated in Brazil, which are: Banana” (Musa spp.), “Coco” (Cocos nucifera), Curauá (Ananas erectifolius), Fique (Furcraea andina), Piteira” (Furcraea gigantea), Sisal(Agave sisalana) and “Taboa” (Typha domingensis). The tests for determining the percent dry completely, extractives soluble in cold water, in hot water, in sodium hydroxide 1% and in ethanol-toluene, and the percentages of ash, hydrophobicity, lignin, holocellulose and cellulose were performed at the Department of Environmental Sciences, Agronomy College (FCA) of UNESP – Botucatu, São Paulo State. It also presents a literature review about these fibers and their potential applications. Differences between the results obtained and those found by other authors are possibly explained by variations on the origin of plant material, the harvest season, the climate and soil where they were grown. However, the results and the methodology used, serve as a basis for further studies with natural fibers

This study aimed to evaluate the efficiency of natural biocides, brown and green propolis, for the control of bacterial contamination in the production of sugarcane spirit. The treatments consisted of brown and green propolis extracts, ampicillin, and a control and were assessed at the beginning and end of harvest season in ten fermentation cycles. In the microbiological analyses, the lactic acid bacteria were quantified in the inoculum before and after the treatment with biocides, and the viability of yeast cells during fermentation was evaluated. The levels of acids, glycerol, total residual reducing sugars, and ethanol were analyzed for the wine resulting from each fermentation cycle. A reduction in the number of bacterial contaminants in the inoculum in the treatments with the natural biocides was observed, but it did not affect the viability of yeast cells. The control of the contaminants led to the production of higher levels of ethanol and reduced acidity in the wine produced. The results of the use of brown and green propolis to control the growth microorganisms in the fermentation of sugarcane spirit can be of great importance for using alternative strategies to synthetic antibacterials in fermentation processes including other distilled beverage or spirits.

The evolution of sugar cane mechanized harvesting made the sector to question the current row spacing used due to its influence on soil compaction. The aim of this study was to evaluate the soil hydro-physical attributes in two row spacings after the farm machinery traffic. The treatments were conducted in a randomized block design with twelve repetitions, being subjected to the variance analyze in double factorial arrangement. The bulk density, the gravimetric water content, and the soil cone index along the position of crop lines (LC) and 0,1m from the row (LP) at the range of depth of 0 to 0.2m and 0.2 to 0.4m were assessed in both row spacings after the fourth harvest season. The results showed that the row spacings of 1.4 and 1.5m did not affect the values of bulk density and gravimetric water content of the soil in all ranges of depth and sample positions studied. However, in the depth range of 0.2 to 0.4 m, the values of soil cone index (IC) in the row spacing of 1.5 m were higher than the values in row spacing of 1.4 m, at both sampling positions. Regardless of row spacing and sample position, the values of soil cone index in the depth range of 0.2 to 0.4m were higher than the depth range of 0 to 0.2m.

The starch market has been growing and improving in recent years, leading to a search for products with specific characteristics that meet the industrial requirements. This work aimed to evaluate the centesimal composition of potato tubers cv Pirassu and its industrial potential. The potato cv Pirassu was cultivated in Pouso Alegre, mountainous region south of Minas Gerais state, with planting season in August and harvest season in November, 2011. The tubers were analyzed for color, pulp and centesimal composition. The starch extract was analyzed for centesimal composition, phosphorus content, apparent amylose, pasting properties and thermal properties. The results showed that the content of dry matter, total soluble sugar and starch of tubers, are compatible for processing for potato chips. The starch of this cultivate showed important viscosity characteristics for food industry such as: heat resistance and friction, good final viscosity and low granular organization.

Frequent inquiry from wheat growers in Nebraska and others as to the relative merits of the combined harvester-thresher as an efficienct and economical harvesting machine led the Nebraska Agricultural College to make a study of this problem in the summer of 1926. The work was carried on by the Departments of Rural Economics and Agricultural Engineering, cooperating with the United States Department of Agriculture which was conducting a similar survey in different parts of the United States. Perkins county, Nebraska, was the area selected for study as it is more or less typical of those parts of the state where combines are used extensively. The purpose of this circular is merely to give such informaition as is available regarding harvesting costs by different methods in Nebraska and not to recommend one method over another since location, acreage, climatic conditions, and topopgraphy all have their influence in determining the most economic method for different communities.
