This article analyzes the integration of the TPACK (Technological, Pedagogical, and Content Knowledge) and SAMR (Substitution, Augmentation, Modification, and Redefinition) models as a theoretical-methodological framework to guide and evaluate pedagogical practices mediated by digital technologies in Mathematics Education. The articulation between these models allows for an understanding not only of the knowled...
This review is focused on the research, innovation and technological breakthroughs on marine invertebrate collagens and their applications. The findings reveal that research dates back to the 1970s, and after a period of reduced activity, interest in collagens from several marine invertebrate groups was renewed around 2008, likely driven by the increased commercial interest in these biomolecules of marine origi...
RESUMO Introduzido na segunda metade do século XX em Portugal, o achigã (Micropterus salmoides) pode ser atualmente encontrado na maior parte das albufeiras e reservatórios da Europa Meridional, sendo uma espécie invasora em Portugal e restantes regiões mediterrânicas. Cada vez mais em Portugal, o achigã é uma das espécies mais procuradas em pesca desportiva e, como tal, uma espécie com potencial dinamizador de...
Chemotaxis and niroblue tetrazolium reduction were measured in peripheral blood neutrophils of workers occupationally exposed to lead. These two neutrophil functions were significantly reduced, as compared to controls, even in those workers with blood lead levels and urinary delta-aminolevulinic acid (ALA-U) concentrations below the currently accepted biological limit values of 60 pg/dl and 6 mg/l, respectively...
A Tuberculose é uma doença infeciosa causada pelo Mycobacterium tuberculosis que, apesar do tratamento disponível, constitui uma causa de morbimortalidade global significativa. Pode atingir qualquer órgão, mas afeta principalmente o pulmão, sendo a via aérea, pela inalação de aerossóis ou microgotículas respiratórias contaminadas, a principal forma de infeção. O esforço global nas últimas décadas para um diagnó...
Sheep and goat extensive production systems are very important in the context of global food security and the use of rangelands that have no alternative agricultural use. In such systems, there are enormous challenges to address. These include, for instance, classical production issues, such as nutrition or reproduction, as well as carbon-efficient systems within the climate-change context. An adequate response...
Although there is evidence that pets may help individuals facing significant daily stressors, and that they may enhance the well-being of their owners, little is known about the benefits of pets for job performance. Since the COVID-19 pandemic crisis, teleworking was a strategy implemented in many countries to reduce the virus widespread and to assure organizational productivity. Those who work from home and wh...
