Analogies, metaphors, and wondering about the future: Lay sense-making around s...

Drawing on social representations theory, we explore how the public make sense of the unfamiliar, taking as the example a novel technology: synthetic meat. Data from an online deliberation study and eighteen focus groups in Belgium, Portugal and the UK indicated that the various strategies of sense-making afforded different levels of critical thinking about synthetic meat. Anchoring to genetic modification, met...

Application of biophysical factors and molecular markers to explain spatial gen...

The strawberry tree (Arbutus unedo L.) is a native species, water stress and low fertility soils tolerant, actively resistant to wildfires and widely distributed in Portugal. The fruit is used in the spirit production, the main source of income. Red fruits, with antioxidant potential, represent, also, a new market opportunity. The geographical isolation and extinction-recolonization dynamics are two factors cau...

Fístula artério-venosa pulmonar: uma causa rara de cianose

RESUMO Apresenta-se o caso de um rapaz de 11 anos, referenciado por episódios recorrentes de dispneia de esforço e dor torácica associados a habitus marfanoide. Apresentava tórax com pectus excavatum exuberante e circulação venosa colateral superficial, cianose ungueal permanente, unhas em vidro de relógio e hipoxemia. A avaliação cardiológica revelou prolapso mitral e raiz da aorta não dilatada. A ressonância ...

Anafilaxia induzida pelo frio - caso clínico

Introdução: A urticária ao frio, rara em idade pediátrica, caracteriza-se pela ocorrência de urticária e/ou angioedema após exposição ao frio. Na maioria dos casos é idiopática; causas secundárias incluem crioglobulinémia, défices do complemento, vasculites, neoplasias e doenças infecciosas. Habitualmente é benigna e auto-limitada, no entanto reacções sistémicas potencialmente fatais podem ocorrer. Caso Clínico...

A global modelling program for co-rotating twin-screw extruders

A global plasticating modeling software for twin screw extruders is presented. The program computes the evolution of pressure, average and maximum temperature, shear rate, viscosity, mechanical power consumption, degree of fill, residence time and mixing along a sequence of the various elements (conveying, left handed and kneading blocks) that are used to assemble a typical screw. Modeling is performed from hop...

Extrusion scale-up : an optimization-based methodology

Given a reference extruder with a certain geometry and operating point, the aim of scale-up is to define the geometry and operating conditions of a target extruder (generally of significantly different size) in order to subject the material being processed to the same flow and heat transfer conditions, thus yielding products with the same characteristics. Since existing scale-up rules are crude, as they usually...
