- Acidic waste cooking oil valorization by biodiesel synthesis catalyzed by hydrogen sulfate 1-butyl-3-methylimidazoliumPublication . Baú, Ana; Lenzi, Giane G.; Ribeiro, António E.; Queiroz, Ana; Brito, PauloBiodiesel is a fuel that shows growing demand as a promising alternative to petroleum-derived fuels. It is produced by esterification or transesterification reactions from renewable raw materials such as animal fats and vegetable oils , where the presence of catalysts is used for an effective conversion. The basic catalysts are very sensitive to the presence of water and FFAs, promoting saponification reactions. On the other hand, the use of acid catalysts means reaction times up to 4000 times higher, higher alcohol/oil molar ratios and higher reaction temperatures. In this context, Ionic Liquids (ILs) used as catalysts, come as a viable alternative to overcome these problems in biodiesel production processes. Imidazolium-based ILs, have been extensively studied, mainly due to their specific characteristics such as, low pressure and ability for self-organization in different states.

Marinho, Ana Beatriz; Magalhães, Ana Rita; Martins, Cátia; Gonçalves, Jéssica Maria; Coelho, Joana C.M.M.; Pereira, Olívia R.Introdução: 422 milhões de pessoas em todo o mundo foram diagnosticados com Diabetes mellitus (DM) em 2014 [1], pelo que a vigilância, prevenção e controlo da doença e suas complicações é fundamental. O tratamento farmacológico é fundamental para o controlo da DM, tendo o profissional de Farmácia um papel basilar para o sucesso do tratamento [2]. Objetivos: Avaliar e caracterizar o aconselhamento farmacêutico pelos profissionais de Farmácia a utentes com DM em Farmácias Comunitárias de Fafe, Guimarães e Lixa. Material e Métodos: Estudo observacional, transversal e descritivo-correlacional. A população alvo englobou os profissionais de farmácia de Farmácias Comunitárias das localidades de Fafe, Guimarães e Lixa. A amostra, do tipo não probabilística acidental, foi constituída por 111 indivíduos. Para recolha de dados recorreu-se a um questionário de autopreenchimento e para a análise, tratamento e organização dos dados utilizou-se o programa SPSS, versão 22. Resultados: A maioria dos profissionais de Farmácia é do género feminino (75,7%) com idades entre os 22 e 70 anos (48±8 anos), solteiro (51,4%) e licenciado (51,4%). Relativamente à profissão, 50,5% são Farmacêuticos, 43,2% Técnicos de Farmácia e 6,3% Auxiliares de Farmácia, em Farmácias Comunitárias de Fafe (45,9%), Guimarães (38,7%) e Lixa (15,3%). Relativamente ao aconselhamento farmacêutico, foram encontrados valores médios de 84%, sendo que profissionais com 1 a 5 anos de experiência apresentaram valores superiores (89%, p=0,028). Todos os profissionais indicaram que advertem o utente relativamente à importância da adesão à terapêutica. Ainda, 9% dos profissionais de Farmácia (n=10) realizam seguimento farmacoterapêutico em DM (5), hipercolesterolemia (2) e hipertensão arterial (2). Para o aconselhamento farmacêutico em utentes com DM, o valor médio foi de 75%, com valores superiores para profissionais de Farmácias Comunitárias de Fafe (80%, p<0,001). 27% dos profissionais de Farmácia participou num curso sobre DM, em média há 3,8 anos, com a duração de 9,2 horas. Conclusões: Foram obtidos valores elevados para o aconselhamento farmacêutico a utentes com DM (75%), sobretudo em profissionais de farmácia de Fafe. É ainda importante referir que a DM é uma das doenças para as quais mais se realiza seguimento farmacoterapêutico.
- Adaptability of new provenances of Quercus suber in Trás-os-Montes: its importance for the sustainability of the forest systemsPublication . Patrício, Maria Sameiro; Nunes, Luís; Monteiro, Maria do Loreto; Almeida, HelenaQuercus suber (Cork oak), an important species in the areas of Mediterranean influence, presents high potential of expansion regarding expected climatic changes. Nowadays, cork oak area in Trás-os-Montes is 6380 hectares and is an important species to consider in the adaptive silviculture strategies in response to the climatic changes. Cork oak woodlands plays an important role on the rural economy, as a source of cork, high quality fruits for cattle, pastures, aromatic and medicinal plants and game habitat. Despite its ecological and socio-economic importance, cork oak adaptability to environmental conditions is poorly understood. Furthermore, climate change scenarios foreseen enhanced water deficits in the Mediterranean region and therefore, to allocate the most adequate seed sources to each set of climatic conditions in future afforestation activities, is an important task for forest landowners. Considering that an important source of variation in the characteristics related with adaptability may be at the provenance level, we evaluated inter-provenance variability at a trial in Mogadouro (Trás-os-Montes). Such trial is part of a multi-locality provenance test belonging to an Euforgen network, where 35 populations from the natural cork oak distribution area are represented. After ten years, results point out the importance of considering the seed origin: significant differences between populations were observed for survival and height. The highest growth is being observed in the Moroccan provenances and French ones showed lowest survival

- Adesão à terapêutica em idosos polimedicadosPublication . Geraldo, Inês; Pereira, Olívia R.; Pinto, Isabel C.Polypharmacy, consists of the simultaneous and chronic use of different drugs, is frequent in elderly people (age≥ 65 years) and commits the patient's adherence to therapy, necessary to a successfully treatment. Objectives: Review the scientific evidences of adherence to therapy and polypharmacy in elderly, since this age group is more vulnerable to the use of different drugs. Materials and Methods: A review of published studies between 2005 and July 2015 was carried out using the Pubmed, B-on and SciELO databases, to search the following terms: elderly, polypharmacy, multidrug, polymedicated elderly and therapy adherence. Were used as exclusion criteria: age under 65, seniors not polymedicated, studies in other languages than Portuguese or English, studies published before 2005. Of the 31 studies initially selected, 8 were excluded as meeting any of the exclusion criteria and 23 articles were included in the review. Results and Discussion: The aging process is associated to various diseases, contributing to polypharmacy. In fact, more than half of elderly taking four or more drugs daily and this number increase with the age. Other important problem related to polypharmacy in elderly is the therapy adherence. Besides the variations between studies, the authors indicate values of non-adherence between 20 and 60%, which results in a range of health problems arising out of the increasing of adverse effects, drug-drug interactions, being this risk associated to the number of drugs consumed. Conclusion: More than half of elderly are polymedicated, with a considerable proportion of elderly non-adherent to therapy, which is associated with consequent health risks.
- Adherence to therapeutic in outpatients: literature reviewPublication . Ribeiro, Maria Isabel; Roque, Fátima; Nascimento, Luís; Herdeiro, M.T.F.Non‐adherence to therapeutic with chronic treatments may compromise patient health, increase care costs and lead to unnecessary consultations and diagnoses, as well as additional treatments with potentially serious side effects1‐5, which can cause significant negative impacts on patients' quality of life5. Chronic diseases, due to their intrinsic nature, are particularly susceptible to non‐adhesion5. According to the World Health Organization (WHO), inadequate adherence to drug therapy in chronic diseases is considered a worldwide problem of great magnitude6. In developed countries only 50% of individuals suffering from chronic diseases adhere to drug treatments. While precarious access to health care, lack of adequate diagnosis and limited access to medicines, and poor adherence to drug therapy in developing countries are conditions that challenge successful chronic disease.
- Adolescents perception of parents and peers diet and physical activity behaviour and encouragementPublication . Ferro-Lebres, Vera; Ribeiro, José Carlos; Moreira, PedroIt has been well documented that parents and peers behaviour influence children and adolescents, namely regarding physical activity and eating behaviours. It is fundamental to understand how adolescents perceive their parents and peers behaviour and stimulus to adolescents own behaviour. This research aimed to study the perception Portuguese adolescents have about their parents and peers behaviour and the stimulus to adolescents own physical activity and eating behaviour. A questionnaire about adolescents’ perception of parents and peers behavior and stimulus was design specially for this research. Data from a 748 sample, mean age 16,7 years (SD=2,0) show that most adolescents perceive that both parents have always/ almost always healthy diets (92,2% mothers; 83,6%fathers) and are always/almost always physically active (53,7% mothers; 63,4%fathers). Adolescents also perceive parents to encourage them to have healthy diets always/almost always (93,9% mothers; 88,0%fathers) and to be physically active always/almost always (86,3% mothers; 88,8%fathers). A Cohen’s kappa moderate consistency among perception of fathers and mothers stimulus was found either to healthy diet (0.47; p <0.001), and physical activity (0.42; p <0.001); and between perception of peers stimulus and behaviour (0.45; p<0.001). A low agreement was found between perception of parents encouragement and own behaviour. These results suggest that the low consistency between the perception of parents behaviour and stimulus to adolescents behaviour is possibly one of the reasons way adolescent’s continue to have poor diets and physical activity levels. Future interventions must consider involving parents and reinforce the importance of changing to a healthier way their lifestyles.
- Adsorption equilibrium of fructose, glucose and sucrose for cationic resins in the sodium and potassium formPublication . Nobre, Clarisse; Santos, M.J.; Dominguez, Ana; Torres, Duarte; Peres, António M.; Rocha, Isabel; Ferreira, Eugénio C.; Rodrigues, Lígia R.; Teixeira, JoséSeparation of glucose from mixtures of fructose and sucrose in molasses is a major challenge in industrial sugar chromatographic separations. The efficiency of a chromatographic process is largely dependent on the adsorbent used. Sulfonated poly(styrene-co-divinylbenzene) (PS-DVB) ion exchange resins are the most frequently used for sugars separation, generally in a cationic form. The cation will complex with the hydroxyl group of the sugar leading to a selective adsorption according to the orientation of the hydroxyl group. Thus, the conformation of the sugar determines its relative affinity for the resin and its distribution coefficient. Consequently, fructose forms the more stable sugar-cation complex being preferentially adsorbed in the resin followed by glucose. Sucrose interacts very weakly with the cation and is partially or totally excluded from the resin matrix owing to its larger molecular size. The separation process is usually carried out at high temperatures. However, this implies high energy costs and an elevated level of hydrolysis. Adsorption isotherms of the sugars present in a mixture are a very important parameter for the selection of the adsorbent to be used in the chromatographic separation. Therefore, in this study, the adsorption isotherms of glucose, fructose and sucrose were determined for two resins of PS-DVB in the sodium and potassium forms. Potassium and sodium are the most recommended cations for the separation of sucrose, fructose and glucose. The sodium and potassium resins matrix used in this work consist in meshes of 500-600 μm and 290-350 μm, respectively. Solutions with single and multi-component mixtures of the three sugars were used at 25ºC and 40ºC. A static method was used to determine the equilibrium adsorptions: 3.5 mL of solutions with different sugar concentrations were added to a known amount of adsorvent. The mixture was held for 8h under agitation and a fixed temperature and a final concentration in equilibrium with resin was determined by HPLC. As expected, the results achieved showed that for all the conditions, fructose is the most adsorved sugar followed by glucose and sucrose. For both resins, the increase of temperature conducted to a decrease on the adsorption constant for all the sugars in the mono-component mixtures. Nevertheless, the adsorption in multi-component mixtures was not significantly affected by the temperature in the sodium resin, and regarding the potassium resin only a small increase in the adsorption was observed. Multi-component mixtures at 25 ºC showed a decrease in the adsorption as compared with mono-component mixtures. However, at 40ºC the adsorption observed for the multi-component mixtures was higher than the observed for the mono-component ones. The sugars that demonstrated lower selectivity values were fructose/glucose since these sugars have the same molecular weight. Sucrose/fructose selectivity showed a higher value when compared with sucrose/glucose because of the complex formed between fructose and the resin. This profile was found for both resins used, regardless of temperature. Selectivity of both resins decreased with the increase of the temperature values. Nevertheless, the selectivity obtained for the potassium resin was higher as compared to the selectivity obtained for the sodium resin. In sum, potassium resin appears to be the most suitable adsorvent and an operational temperature of 25 ºC showed the best results.
- Allometric equations for predicting mineralomass in high-forest chestnut stands in PortugalPublication . Patrício, Maria Sameiro; Tomé, MargaridaThe evaluation of nutrients in biomass tree-components is a process time consuming and expensive, often involving tree felling, not always possible or desirable. Thus, mineralomass prediction equations are an important tool for the quantification of the nutrients exported in management and harvesting activities towards to its replacement and sustainable management as well as to evaluate the effect of other disturbances in the balance of ecosystems. Thus, given the importance of the relationship of biomass and nutrients (mineralomass) for dynamic and sustainable management of chestnut woodlands, aboveground mineralomass was studied in sweet chestnut (Castanea sativa Mill.) high forest stands located in Northern Portugal. Nutrient specific prediction equations that allow estimating the mineralomass (N, P, K, Ca, Mg, S, B and C) above the ground, total and by components: stem-wood, stem-bark, branches, leaves and flowers, based on tree dendrometric variables, DBH (diameter breast height) and total height, were developed. Linear and non-linear regression estimation methods were used. Data analysis is based on information collected in destructive analysis of thirty-four felled trees, distributed by the existing diameter classes (10-65 cm) in three adult chestnut stands. Several linear and nonlinear equations were fitted by the least squares method to select models. A simultaneous fit by SUR method using iterative seemingly unrelated regression (ITSUR) was used for the final selected models. The best fitting models are presented.
