Numerical and experimental investigations of three-dimensional container fillin...
Tomé, M. F.; Castelo, A.; Nóbrega, J. M.; Carneiro, O. S.; Paulo, G. S.; Pereira, F. T.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...
Caso radiológico: Pseudo-obstrução intestinal ileocólica
Pinto, M.; Pereira, F.; Macedo, F.We present the clinical case of an 11-year-old boy with cerebral palsy. He was observed in the Gastroenterology Department for the presence of recurrent episodes of vomiting (bilious and/or fecaloides) with one year of development, preceded by pallor, sweating, sense of abdominal pain and abdominal swelling. Recently the episodes occur every week. The abdominal Computed Tomography (CT) showed megacolon compatib...
Caso endoscópico
Pereira, F.We present the case of a ten-year-old female patient referred to Gastroenterolgy consultation for abdominal pain and cramping, usually worse after eating, recurring diarrhoea, hypochromic and microcytic anaemia with low serum iron and ferritin levels. Moderate to severe Crohn’s disease of the terminal ileum e right colon (L3) was diagnosed, based on endoscopic image and biopsy. The patient was treated with pred...
Caso endoscópico: compressão extrínseca duodenal
Pereira, F.We present a case report of a child with several crises of upper abdominal pain and vomiting for two years, resolved with metoclopramide and butilscopulamine suggesting upper digestive intermittent obstruction. She is symptoms free between theses episodes. The upper digestive endoscopy showed an aspect suggestive of submucosal lesion or extrinsic compression in the second portion of the duodenum. The abdominal ...
Auditoria à prática profilática e incidência de náuseas e vómitos pós-operatóri...
Mota, A.; Saraiva, A.; Duarte, S.; Pereira, F.; Araújo, M.; Amadeu, E.Introdução: As NVPO são uma das principais queixas dos doentes do pós-operatório. Este trabalho teve como objetivo registar a prática farmacológica para profilaxia de NVPO em cirurgia programada e avaliar a sua eficácia. Metodologia: Incluídos todos os doentes submetidos a cirurgia programada das especialidades de Cirurgia Geral, Urologia e Cirurgia Vascular entre 3 e 21 de Dezembro de 2012. Excluídos se alta...
Teste à cabeceira e confirmação positiva da transfusão: dois procedimentos do s...
Barradas, A; Barra, A; Cardoso, E; Costa, C; Gil, A; Pereira, FA hemovigilância é definida “como o conjunto de procedimentos de vigilância relacionados com eventos ou reações adversas graves ou inesperadas em dadores ou recetores” e o acompanhamento epidemiológico dos dadores. Tem como objetivo final a prevenção da recorrência destes eventos ou reacções [1]. A confirmação positiva da transfusão e o teste à cabeceira são dois dos procedimentos do sistema de hemovigilância, ...
Biochemical Methane Potential of raw and pre-treated meat-processing wastes
Cavaleiro, A. J.; Ferreira, T.; Pereira, F. R.; Tommaso, Giovana; Alves, M. M.Raw and pre-treated greaves and rinds, two meat-processing wastes, were assessed for biochemical methane potential (BMP). Combinations of temperature (25, 55, 70 and 120°C), NaOH (0.3 g g-1 waste volatile solids) and lipase from Candida rugosa (10 U g-1 fat) were applied to promote wastes hydrolysis, and the effect on BMP was evaluated. COD solubilisation was higher (66% for greaves; 55% for rinds) when greaves...
Effect of pH and pressure on syngas fermentation by anaerobic mixed cultures
Pereira, F. M.; Alves, M. M.; Sousa, D. Z.Syngas fermentation by mesophilic anaerobic mixed cultures was studied, regarding the effect of initial medium pH (5.8, 6.9 and 7.6) and total initial syngas pressure (1.0, 1.75 and 2.5 atm) in methane production and other alternative products (acids and alcohols). Complete consumption of CO and H2 was achieved in less than 72 h at 1.0 atm syngas, and within 240 h for higher syngas pressures. The highest specif...
Spatial memory impairments in a prediabetic rat model
Soares, E.; Prediger, R. D.; Nunes, S.; Castro, A. A.; Viana, S .D.; Lemos, C.; Souza, C. M. De; Agostinho, P.; Cunha, R. A.; Carvalho, E.Diabetes is associated with an increased risk for brain disorders, namely cognitive impairments associated with hippocampal dysfunction underlying diabetic encephalopathy. However, the impact of a prediabetic state on cognitive function is unknown. Therefore, we now investigated whether spatial learning and memory deficits and the underlying hippocampal dysfunction were already present in a prediabetic animal m...
Violência Doméstica. Manual de Recursos para a Rede de Intervenção Integrada do...
Lopes, M. J.; Gemito, L.; Pereira, F.A violência doméstica tem vindo, cada vez mais, a assumir uma enorme centralidade no debate público. Sinal dessa centralidade crescente traduz-se na ocupação frequente do es-paço mediático com notícias quantas vezes escandalosas, se não mesmo chocantes e pró-prias de filmes de terror. Todavia, a discussão relativa ao fenómeno da violência doméstica precisa de ultrapassar o ritmo da ocorrência de fenómenos medi...
