This work employs numerical and experimental approaches to investigate three-dimensional container filling with Newtonian viscous fluids. For this purpose, a computer code developed for simulating three-dimensional free surface flows has been used. The CFD Freeflow3D code was specifically designed to deal with unsteady three-dimensional flows possessing multiple moving free surfaces. An experimental apparatus t...
Virgin olive oil (VOO) has many potential health benefits, including the amelioration of inflammatory processes. In part, this is known to occur through the modification of the endothelial function, leading to a decrease of the levels of cell-adhesion molecules (CAMs), including the inter-cellular adhesion molecule 1 (ICAM-1) and the vascular cell adhesion molecule 1 (VCAM-1). Importantly, virgin olive oil is a...
Os autores apresentam um caso clínico de acidúria 3-hidroxi-3-metilglutárica (3HMG) numa criança do sexo feminino, de 2 anos de idade, com síndrome de Down. Apresentava hipoglicemia não cetótica, acidose metabólica, encefalopatia e um perfil anormal de ácidos orgânicos urinários, característico de acidúria 3HMG.A demonstração da deficiência da enzima 3-hidroxi-3-metilglutaril-CoA liase (HMG-CoA liase) em cultur...
A new semi-organic compound, 6-aminoquinolinium iodide monohydrate (I), has been synthesized and characterized by single crystal X-ray diffraction, UV–vis absorption and fluorescence spectroscopy and nonlinear optical (NLO) measurements. The second- and third-order NLO responses were investigated with the second- and third-harmonic Maker fringes techniques, carried out on thin films at a fundamental wavelength ...
A aplicação de chorume ao solo por injeção, ou após tratamento através da separação mecânica de sólidos ou da acidificação, são práticas consideradas como suscetíveis de reduzirem emissões de amoníaco (NH3). Com o objetivo de avaliar, em condições mediterrânicas, o efeito destas técnicas de aplicação de chorume na produção de silagem de milho e na eficiência da utilização pelas plantas do azoto (N) aplicado, fo...
Scorzonera is a threatened species in Portugal. Given the role of temperature in germination and seedling recruitment, the performance of total germination, lag of germination, duration of germination, shape of germination, root and hypocotyl length, and relative root growth of scorzonera was investigated under constant and alternating temperatures between 10 and 25ºC. Because of scorzonera’s rarity and threate...
The histological alterations and the expression of metallothionein (MTs) and heat shock protein (Hsp70) in the kidney of Wistar rats after thiram fungicide exposure were evaluated. Animals were distributed into three groups: standard diet group, standard diet + corn oil group and thiram group. Significant differences were found (P<0,05) in the evolution of body weight between rats in the thiram group and those ...
The objective of the present study was to evaluate the effects of female age (1, 2 and 3-year-old) and month of laying (March, April and May) on the physical characteristics of the red-legged partridge eggs reared in captivity. O objetivo do presente estudo foi avaliar os efeitos da idade das fêmeas (um, dois e três anos) e do mês de postura (março, abril e maio) sobre as características físic...
