Efeito directo de cada norma (IAS/IFRS) nas principais rubricas e indicadores ...

Este estudo foi desenvolvido com o objectivo de analisar o impacto produzido pela introdução das International Accounting Standards/ International Financial Reporting Standards (IAS/IFRS) e avaliar o efeito directo de cada norma nas principais rubricas e indicadores. Para tanto, levantámos duas questões: Q1: A alteração do normativo POC/DC para as IAS/IFRS produziu alterações significativas na informação financ...

Endothelial dysfunction – a major mediator of diabetic vascular disease

The vascular endothelium is a multifunctional organ and is critically involved in modulating vascular tone and structure. Endothelial cells produce a wide range of factors that also regulate cellular adhesion, thromboresistance, smooth muscle cell proliferation, and vessel wall inflammation. Thus, endothelial function is important for the homeostasis of the body and its dysfunction is associated with several pa...

Relationship between sports sector, sports modality and the academic success

The purpose of the study was to verify if the sports sector: school sport, federated or both, are or not associated with rates of academic success of young people. The study involved a stratified random sample of students belonging to the 3rd cycle and secondary education in schools in Madeira Island, Portugal, a total of 2443 students (12.6%). For data collection was constructed and validated an anonymous ques...

Durability of steel fiber reinforced self-compacting concrete

Publicado em "Proceedings of the 5th International Conference on The Concrete Future", ISBN 978-981-07-6067-0 ; For conventional concrete without steel fibers, although still an aspect under discussion, there are some commonly used durability indicators. However, for steel fiber reinforced self-compacting concrete (SFRSCC) literature is sparse and the aspects of durability, particularly corrosion resistance, s...

Extraction of agar from Gelidium corneum using an alternative heating technology

Traditional polysaccharides extraction processes are often performed under heating which makes them time-, energy- and solvent-consuming. The aim of this work was to assess the possibility of using ohmic heating to replace conventional heating in the extraction of seaweed hydrocolloids. This technology is able to heat almost instantaneously the whole volume to be treated, using the ability that most materials h...

Entangled effects of allelic and clonal (genotypic) richness in the resistance ...

Background - The relationship between species diversity and components of ecosystem stability has been extensively studied, whilst the influence of the genetic component of biodiversity remains poorly understood. Here we manipulated both genotypic and allelic richness of the seagrass Zostera noltii, in order to explore their respective influences on the resistance of the experimental population to stress. Thus ...

Ecotechnologies as urban solutions for sustainable water management

Sitagliptin delays progression of renal lesions in a rodent model of type 2 dia...

Immobilization of commercial laccase on spent grain

The aim of this work was to assess the possibility of using beer spent grain (a byproduct of beer’s brewing industry) as a carrier for laccase immobilization. Both adsorption (on spent grain – SG and on digested spent grain – DSG) and covalent binding (using glycidol and glycidol followed by ethylenediamine on DSG) were used. The effect of different immobilization conditions on the immobilization yields and rec...

Conceção e desenvolvimento de ensaio experimental de arrancamento de fibras de ...

Relatório 12-DEC/E-23 ; No âmbito do estudo da durabilidade do betão auto-compactável reforçado com fibras de aço (BACRFA), em especial a corrosão das fibras, surge o presente relatório, que descreve o ensaio experimental de arrancamento de fibras de aço em provetes cilíndricos fissurados, submetidos a ciclos de imersão/secagem em solução contendo cloretos. Todos os elementos constituintes do equipamento...
