Organic residues from agricultural and forest companies in Brazil as useful substrates for cultivation of the edible mushroom Pleurotus ostreatus

We investigated whether highly available organic residues in Brazil can be used as substrates for the production of the oyster mushroom Pleurotus ostreatus, instead of the conventional cultivation using the eucalyptus sawdust substrate. We assessed the mushroom yield on 13 substrates, of which 12 were formulated with different concentrations of organic residues and one with pure eucalyptus sawdust, and verified whether the raw material used in the substrate formula and the concentration of such alternative residues influenced their biological efficiencies. Substrates containing eucalyptus bark resulted in higher mushroom yield than those containing eucalyptus sawdust, which generally resulted in similar mushroom yield to the remaining formulas. Moreover, the raw material and the concentration of each residue affected the biological efficiency of the substrates. We show that the conventional substrate for P. ostreatus can be replaced by substrates easily accessible to producers without loss in productivity. Furthermore, that the concentration of these mixtures affects the mushroom productivity and should be considered when formulating the growth medium.Peer reviewe

Comparing trawl and creel fishing for Norway lobster (Nephrops norvegicus): biological and economic considerations

This study compares the fishing activity and landings of the trawl and creel fisheries for Norway lobster (Nephrops norvegicus (L.)) off the Portuguese coast, and evaluates the financial viability of two vessels typical of each fleet. Crustacean trawlers are part of an industrial fleet that, besides Nephrops, targets deep water shrimps. Creels are used by a multi-gear, multi-target artisanal fleet, fishing only in areas unavailable to trawlers and, when catching Nephrops, set specifically to target this species. Trawlers have in recent years contributed with 85% of the landings in weight, but only 74% in value (2005-2009 average). Despite smaller landings, the Nephrops creel fishery provides individuals of larger size and in better condition, thereby obtaining higher unit prices. Economic viability was also higher for the creel vessel, with trawling being only viable if major costs (such as labor and fuel) are covered by the revenue from other target species (e. g., the rose shrimp). At present, Nephrops populations on the South and SW coast are subject to intense fishing and to a recovery plan. The possibility of reallocation of some of the fishing effort directed at Nephrops from trawlers to creels is discussed in terms of the conservation of the resource and economic return.Foundation for Science and Technology, Portugal: Project "Nephrops survival when escaping from trawls nets and by-catch escaping devices" [PDCT/MAR/59366/2004]; Foundation for Science and Technology, Portugal: Project "Environmental impact of fixing gears in the southwest coast of Portugal.

Gestão hospitalar de equipamentos de proteção individual no enfrentamento à pandemia covid19 / Hospital management of personal protection equipment in addressing the pandemic covid19

A pandemia COVID19 impactou fortemente o mundo no ano de 2020, afetando principalmente o setor hospitalar, demandando cuidados específicos em relação a insumos médicos, equipamentos e mão de obra qualificada. O presente trabalho tem por objetivo a identificação dos fatores influenciadores nos processos de decisão referentes às compras hospitalares feitas durante a pandemia. Foi feito um estudo de caso junto a um hospital do Vale do Paraíba, realizando-se coleta de dados sobre porcentagem de ocupação hospitalar, evolução de gastos, demanda de suprimentos e gerenciamento de estoque, incluindo compras feitas na instituição hospitalar e sua gestão logística. Os resultados são apresentados na forma de tabelas e gráficos, sendo feito levantamento bibliográfico e pesquisa de notícias para fundamentar a análise de custos operacionais, com a discussão dos resultados no contexto da pandemia. A análise apresentada aponta caminhos para equilíbrio e gerenciamento de estoque relativo ao material médico hospitalar em períodos como o da pandemia COVID19.
