Recycling of textile waste by reinforcing earthy render with micro-fiber

Earth construction is worldwide spread. It is a valuable heritage to preserve because of its cultural and socio-economical relevance. Furthermore, earth construction, since it needs significantly less energy than modern construction techniques, and works with local materials, it contributes for thesustainable development. In Portugal, there is an impressive earth construction heritage that requires maintenance....

Mutilação Genital Feminina: o que Sabem os Profissionais de Saúde?

Portugal is considered by the World Health Organization (WHO) a risk country for the practice of Female Genital Mutilation (FGM). Objectives: To evaluate the knowledge that health professionals from Maternity Dr. Alfredo da Costa (MAC) have regarding FGM. Population and Methods: Analysis of surveys delivered to health professionals from MAC (a hospital dedicated to reproductive health), between April and June 2...

Corn cob lightweight concrete for non-structural applications

A lightweight concrete using granulated corn cob (without corn) as an aggregate is proposed in this research work. Taking into account that corn cob, after extracting the corn, is generally considered an agricultural waste, an interesting economic and sustainable benefit may result by using it as a building material. Therefore, it can be an alternative sustainable lightweight aggregate solution in comparison to...

Camada de regularização com agregado de granulado de caroço da espiga de milho

Um conjunto de construções antigas localizadas na região de Trás-os-Montes e Alto Douro, Portugal, apresentam caroços de espiga de milho incorporados na camada de enchimento de paredes exteriores de tabique. Esta descoberta tem vindo a estimular o estudo do potencial da aplicação na construção civil deste resíduo agrícola. Um trabalho de investigação preliminar permitiu concluir que este produto natural apresen...

Argamassa de reboco reforçada com resíduos da indústria têxtil do tipo fio

Este trabalho de investigação pretende estudar o efeito da incorporação de fibras de resíduos da indústria têxtil nas argamassas de reboco e auscultar o potencial deste material compósito. Neste caso, os resíduos da indústria têxtil considerados são fios ou pedaços de tecido ou malhas, e poderão ter uma grande variabilidade material (e.g. composição, espessura, densidade, entre outras). Aspectos relacionados co...

Aging effect on the integrity of traditional Portuguese timber roof structures

Traditional buildings basically include natural and autochthonous construction materials and are built with sustainable construction techniques. The knowledge of these materials’s state and construction techniques is required for a proper conservation/renovation work. It is well known that the lack of maintenance is one of the main causes that contribute to the high degree of degradation that the Portuguese tra...

Lack of evidence for regulation of cardiac P-type ATPases and MAP kinases in tr...

The regulatory function of α1B-adrenoceptors in mammalian heart homeostasis is controversial. The objective of the present study was to characterize the expression/activity of key proteins implicated in cardiac calcium handling (Na+/K+-ATPase and Ca2+-ATPases) and growth (ERK1/2, JNK1/2 and p38) in mice with cardiac-selective overexpression of constitutively active mutant α1B-adrenoceptor (CAMα1B...

Differential effects of isoproterenol on the activity of angiotensin-converting...

The excessive stimulation of beta-adrenergic receptors in the heart induces myocardial hypertrophy. There are several experimental data suggesting that this hypertrophy may also depend, at least partially, on the increase of local production of angiotensin II secondary to the activation of the cardiac renin-angiotensin system. In this study we investigated the effects of isoproterenol on the activity of angiote...
