3D Printed Laryngoscope For Endotracheal Intubation

ArticleThis study aims to determine whether additive manufacturing can be used to produce a safe and reliable video laryngoscope. Different designs were proposed and evaluated with a mannequin for usability. Finite element analysis (FEA) was done to estimate the stress distribution, maximum displacement at the tip, and factor of safety. A final 3D printed laryngoscope design was chosen on the basis of this evaluation. Future work on validation, whether it is safe to be used, and the limitations of the device are discussed. The device will be printed under predetermined settings and material to conform to the validation

Water scarcity, property regimes and irrigation management in Sonjo, Tanzania

This article explores the dynamics of property rights in irrigation water in Sonjo, Tanzania. It analyses an unsuccessful attempt by the ruling political group to change the institutional arrangements of water control, to serve better their private goals. This example shows that not all internal institutional innovations in the field of utilising natural resources lead to increased efficiency of the system from the point of view of the whole community. We draw on New Institutional Economics (NIE) and Common Property Resource Management (CPRM) theory to analyse the way in which it was possible that those few within Sonjo society who are formally/nominally 'the owners' of water sought to privatise de facto collective use rights of all community members. We consider why this was done in some, but not all, Sonjo communities, and we describe why this process has eventually failed.

Orchid Bees of forest fragments in Southwestern Amazonia

As abelhas pertencentes à tribo Euglossini são conhecidas como abelhas das orquídeas. Em geral, áreas com maior cobertura de vegetação apresentam maior abundância e diversidade dessas abelhas. Esse estudo investigou os efeitos da fragmentação florestal sobre as assembleias de abelhas Euglossini na região do município de Rio Branco, Acre e arredores. Os fragmentos florestais com tamanhos variados foram selecionados para a área de estudo e classificados como urbanos e rurais. As abelhas foram coletadas entre dezembro de 2005 e agosto de 2006. Um total de 3.675 machos pertencentes a quatro gêneros e 36 espécies foi coletado. De modo geral, abundância e riqueza de Euglossini não foram estatisticamente diferentes entre fragmentos urbanos e rurais. O índice de borda do fragmento foi preditor de riqueza e diversidade das abelhas. A conectividade estimada também foi preditora da riqueza. Fragmentos com maior similaridade em relação à estrutura paisagística foram também mais similares em relação à composição faunística
