O trabalho aqui apresentado visa estudar o impacto do Programa de Alargamento da Rede de Equipamentos Sociais (PARES) na Rede de Serviços e Equipamentos Sociais (RSES) do Distrito de Aveiro. O PARES foi lançado com objetivos muito precisos e ambiciosos no que concerne ao alargamento da capacidade respostas sociais nas áreas da infância e juventude, população idosa e pessoas com deficiência, incentivo ao investi...
The conditions of temperature, moisture content, and inoculum rate able to maximize the production of fructooligosaccharides (FOS) and β-fructofuranosidase (FFase) enzyme by solid-state fermentation were established. Fermentation assays were performed using the support material (coffee silverskin) moistened to 60, 70, or 80 % with a 240-g/l sucrose solution and inoculated with a spore suspension of Aspergillus ...
The emergence of new infections and increase of bacteria drug-resistance rise up the urgent need for the development of new antibacterial agents from natural sources. This study was designed to evaluate the antibacterial activity of the crude methanolic extract (CME) and fractions [hexane (H), dichloromethane (DCM), ethyl acetate (EA) and ethanol (Et)] obtained from Larrea tridentata (Sessé & Moc. Ex DC.) Covil...
This study evaluated the efficacy of different solvents (methanol, ethanol, acetone, hexane, ethyl acetate, water, methanol:water mixtures, ethanol:water mixtures, and acetone:water mixtures) for extracting antioxidant phenolic compounds from brewer’s spent grains (BSGs). The extracts were characterized regarding the contents of total phenols, flavonoids, proteins and reducing sugars. Antioxidant activity was d...
Chemical composition of Larrea tridentata leaves was determined and elevated content of lignin (35.96 % w/w) was found. The present study was proposed in order to evaluate the extraction of bioactive compounds, particularly phenolic compounds, by solid-state fermentation (SSF) of L. tridentata leaves. The basidiomycete Phanerochaete chrysosporium was used in the experiments due to its ability to degrade lignin....
A Língua Gestual Portuguesa (LGP) é a língua natural dos surdos portugueses e a Língua Portuguesa passa a ser a segunda língua, essencialmente na sua versão escrita, uma vez que muitos destes alunos não têm nenhuma proficiência na língua oral da comunidade que os envolve. Devido ao facto de não possuírem acesso tão rápido às informações como os ouvintes, este grupo necessita de um meio escrito ou gestual - visu...
Introdução: A Artrite Reumatoide (AR) e a Fibromialgia (FM) são doenças músculo-esqueléticas e estão entre as causas mais comuns de dor crónica e incapacidade. Apresentam etiopatogenia, clínica, orientação terapêutica e evolução díspares, mas ambas condicionam limitações nas atividades da vida diária e profissionais, deterioração da qualidade de vida e da autoperceção da saúde global, podendo associar-se a pert...
Coffee is one of the most consumed beverages in the world and is the second largest traded commodity after petroleum. Due to the great demand of this product, large amounts of residues are generated in the coffee industry, which are toxic and represent serious environmental problems. Coffee silverskin and spent coffee grounds are the main coffee industry residues, obtained during the beans roasting, and the pro...
Methanol, ethanol, and acetone at four different concentrations (90%, 70%, 50%, and 30% v/v) were used for extraction of phytoestrogens (nordihydroguaiaretic acid (NDGA), kaempferol, and quercetin) from Larrea tridentata leaves. Besides the phytoestrogens extraction, the antioxidant potential, and the contents of total phenols, flavonoids, and protein in the produced extracts were also determined. The solvent a...
