    RESUMEN: El s√≠ndrome coronario agudo es una de las principales causas de morbimortalidad en Espa√Īa. Esta enfermedad produce un descenso del aporte sangu√≠neo al coraz√≥n, por lo que puede desencadenar en isquemia, insuficiencia card√≠aca o, incluso, la muerte s√ļbita del individuo. Una de las cardiopat√≠as con mayor incidencia es el infarto agudo de miocardio (IAM), que se produce por el colapso de al menos una arteria coronaria. Como consecuencia, el m√ļsculo card√≠aco irrigado deja de recibir ox√≠geno y nutrientes, por lo que comienza a isquemizarse. El diagn√≥stico y el tratamiento precoz definir√°n el grado de las secuelas producidas. La expresi√≥n ‚Äúel tiempo es m√ļsculo‚ÄĚ resume la importancia de una actuaci√≥n r√°pida: cuanto m√°s tiempo pase el miocardio sin irrigaci√≥n, mayor ser√° el alcance de la necrosis. Sin embargo, tan importante es el tratamiento de la enfermedad aguda como la prevenci√≥n secundaria y la promoci√≥n de un estilo de vida saludable. Por ello, este documento da visibilidad a la rehabilitaci√≥n card√≠aca, que aborda diferentes actividades para mejorar la situaci√≥n del paciente estable y evitar una recidiva de la enfermedad. Para ello, este trabajo incluye un plan de cuidados estandarizado de enfermer√≠a para la rehabilitaci√≥n card√≠aca, desarrollado mediante la taxonom√≠a NANDA-NOC-NICABSTRACT: Acute coronary syndrome is one of the main causes of morbidity and mortality in Spain. This disease produces a decrease in blood supply to the heart, which can lead to ischemia, cardiac failure or even death. One of the heart diseases with the highest incidence is acute myocardial infarction (AMI), which is caused by the collapse of at least one coronary artery. Consequently, the irrigated heart muscle stops receiving oxygen and nutrients, so it begins to become ischemic. Early diagnosis and treatment will define the degree of sequelae produced. The expression "time is muscle" summarizes the importance of quick action: the longer the myocardium goes without irrigation, the greater the extent of necrosis. However, the treatment of acute illness is just as important as secondary prevention and the promotion of a healthy lifestyle. For this reason, this document gives visibility to cardiac rehabilitation, which addresses different activities to improve the situation of the stable patient and prevent a recurrence of the disease. Furthermore, this work includes a standardized nursing care plan for cardiac rehabilitation, developed using the NANDA-NOC-NIC taxonomyGrado en Enfermer√≠

    Disserta√ß√£o de mestrado em Engenharia IndustrialA Coprax S.A. √© uma empresa hist√≥rica no mercado nacional que comercializa e produz tubagens e acess√≥rios que podem ser aplicadas em redes prediais, climatiza√ß√£o, industria e rega. No entanto, apesar de ser uma empresa com uma boa imagem no mercado, fruto da dedica√ß√£o de todos os seus colaboradores, compete num mercado global com empresas com propostas de valor diferenciadas e com uma escala/dimens√£o diferente. A crescente globaliza√ß√£o que se tem vindo a verificar nas ultimas d√©cadas provocou um incremento muito significativo na quantidade e qualidade de informa√ß√£o que chega ao mercado nacional. Consequentemente, a exig√™ncia dos clientes tem vindo a aumentar de uma forma exponencial assim como o aparecimento de novas solu√ß√Ķes na √°rea das tubagens. A crise econ√≥mica recente afetou todos os setores da nossa economia, no entanto o ramo da constru√ß√£o foi das √°reas mais afetadas e consequentemente todas as empresas na √°rea dos materiais de constru√ß√£o, a Coprax S.A. n√£o foi exce√ß√£o. Com a finalidade de aumentar efici√™ncia da empresa e a qualidade do servi√ßo que √© prestado aos seus clientes, depressa se identificou a √°rea de gest√£o de stocks como um setor onde poderia ser feito um trabalho de melhoria consider√°vel. √Č neste contexto que esta disserta√ß√£o pretende dar um contributo, utilizando como caso de estudo o armaz√©m n√£o produtivo da Coprax S.A. Neste projeto ser√° efetuado um estudo entre classifica√ß√£o e modelos de gest√£o de stocks, que t√™m como finalidade aumentar a competitividade da empresa. A implementa√ß√£o das solu√ß√Ķes apresentadas permitir√° um aumento da efici√™ncia relacionada com o picking e expedi√ß√£o do material, a otimiza√ß√£o do espa√ßo dispon√≠vel, a redu√ß√£o de stock obsoleto e com baixa rota√ß√£o assim como o aumento generalizado da efici√™ncia associada a gest√£o do stocks da empresa.Coprax S.A. is a historical company in the Portuguese market that sells and produces pipes and fittings that can be applied in water supply networks, air conditioning, industry and irrigation. However, despite being a company with a good image in the market, as a result of the dedication of all its employees, it competes in a global market with companies with differentiated value propositions and a different scale/dimension. The increasing globalization that has been taking place in the last decades has caused a very significant increase in the quantity and quality of information that reaches the national market. As a result, customer demand has been increasing exponentially as well as the appearance of new piping solutions. The recent economic crisis has affected all sectors of our economy, but construction has been one of the most affected areas and consequently all companies in the field of building materials, Coprax S.A. was no exception. In order to increase the company's efficiency and the quality of service provided to its customers, the stock management area was quickly identified as a sector where considerable improvement work could be done. It‚Äôs in this context that this dissertation intends to contribute, using as a case study the non-productive warehouse of Coprax S.A. In this project will be made a study between classification and stock management models, which aim to increase the company's competitiveness. The implementation of the presented solutions will allow an increase in efficiency related to picking and shipping of material, optimization of available space, reduction of obsolete and low rotation stock as well as a general increase in efficiency associated with the company's stock management

    Tese de doutoramento em BiologyA cultura da videira tem uma elevada relev√Ęncia econ√≥mica e cultural. Atualmente, esta esp√©cie enfrenta desafios dif√≠ceis pois, num contexto de altera√ß√Ķes clim√°ticas, a severidade dos stresses abi√≥ticos est√° a aumentar, causando impactos negativos na fisiologia da videira, em particular na atividade fotossint√©tica e na regula√ß√£o do estado h√≠drico. Desta forma, uma gest√£o adequada da luz/radia√ß√£o na copa √© essencial para garantir uma boa produ√ß√£o de uvas e vinho. Previamente, mostr√°mos que o exocarpo e os tegumentos das sementes de bagos de uva de uma casta branca (cv. Alvarinho) foram os tecidos mais fotossinteticamente ativos, que essa atividade variou ao longo das fases de desenvolvimento (verde, v√©raison e madura) e em resposta ao microclima de luz (LL - luz baixa; e HL - luz alta). No entanto, a fun√ß√£o da fotoss√≠ntese da uva ainda √© amplamente desconhecida. Neste trabalho pretendemos estudar os efeitos desses dois microclimas de luz e de duas estrat√©gias de mitiga√ß√£o do stresse clim√°tico - aplica√ß√£o foliar de caulino e irriga√ß√£o - na atividade fotossint√©tica, perfil de metabolitos e nos transcritos de genes-alvo desses tecidos do bago de uva, colhidos nessas tr√™s fases de desenvolvimento. Estudos por fluorometria de pulso de amplitude modulada (PAM) mostraram que HL aumentou a efici√™ncia qu√Ęntica m√°xima (Fv/Fm) e a atividade fotossint√©tica (rETR200) de ambos os tecidos da fase verde. Curiosamente, a aplica√ß√£o foliar de caulino aumentou a atividade fotossint√©tica dos exocarpos LL da fase verde em compara√ß√£o com o controlo, enquanto que a irriga√ß√£o diminuiu a atividade fotossint√©tica das sementes HL nas fases v√©raison e madura, especialmente nas videiras de parcelas pulverizadas com caulino. Espectrometria de massa por cromatografia l√≠quida (LCMS) revelou que apenas a ‚Äúirriga√ß√£o‚ÄĚ e o ‚Äúmicroclima de luz‚ÄĚ levaram a diferen√ßas significativas no perfil de metabolitos dos tecidos do bago. An√°lises transcricionais por rea√ß√£o em cadeia da polimerase (qPCR) mostraram que os n√≠veis de transcri√ß√£o de genes codificadores de elementos associados √† fotoss√≠ntese, clorofila sintetase (VvChlSyn) e ribulose-1,5-bisfosfato carboxilase/oxigenase (VvRuBisCO), foram regulados positivamente pelo microclima HL. Paralelamente, o estudo de lipid√≥mica mostrou que as sementes LL tiveram n√≠veis mais altos de √°cidos gordos livres, enquanto que HL levou √† regula√ß√£o positiva de ceramidas na fase verde e triglicer√≠deos e glicerofosfol√≠pidos na fase madura. Globalmente, este trabalho fornece evid√™ncias sobre a contribui√ß√£o da fotoss√≠ntese para a fisiologia do exocarpo e da semente do bago de uva, bem como novos conhecimentos para uma gest√£o adequada das pr√°ticas vit√≠colas.Grapevine is an agriculture crop with high economic and cultural relevance. Currently, this plant species faces a difficult challenge, as in the context of climate changes, the severity of abiotic stresses is increasing, causing negative impacts on grapevine physiology, namely on photosynthetic activity and water status regulation. Therefore, an appropriate management of the light/radiation intercepted by the canopy is essential to ensure a proper grape and wine production. Previously, we showed that grape berry exocarp or skins and seed integuments from a white variety (cv. Alvarinho) were photosynthetically active and that this activity varied along grape berry developmental stages (green, v√©raison and mature) and was responsive to the light microclimate that clusters experienced in the canopy (LL - low light; and HL - high light). However, the function of grape berry photosynthesis is still largely unknown. In this work we intended to study the effects of these two contrasting light microclimates under two short-term climate stress mitigation strategies - foliar kaolin application and irrigation - on the photosynthetic activity, metabolite profile and transcripts of target genes of the same two grape berry tissues, sampled at the same three developmental stages. Pulse amplitude modulation (PAM) fluorometry showed that HL increased the maximum quantum efficiency (Fv/Fm) and photosynthetic activity (rETR200) of both tissues at the green stage. Interestingly, kaolin applied to leaves increased the photosynthetic activity of LL exocarps at green stage as compared with control, while the irrigation decreased the photosynthetic activity of HL seeds at v√©raison and mature stages, especially in those grapevine parcels sprayed with kaolin. Untargeted liquid chromatography mass spectrometry revealed that only ‚Äúirrigation‚ÄĚ and ‚Äúlight microclimate‚ÄĚ led to significant differences in the metabolite composition of the berry tissues. Transcriptional analysis by real-time quantitative polymerase chain reaction showed that the transcript levels of genes encoding photosynthesis-related elements, chlorophyll synthase (VvChlSyn) and ribulose 1,5-bisphosphate carboxylase/oxygenase (VvRuBisCO), were up-regulated by HL microclimate. In parallel, lipidomics analysis showed that LL seeds had higher relative levels of free fatty acids, while HL led to up-regulation of ceramides at green stage and triacylglycerols and glycerophospholipids at mature stage. Overall, this work provides insights for the contribution of tissue-specific photosynthesis to grape berry‚Äôs skin and seed physiology and metabolome, as well as new knowledge for a good management of viticultural practices.Andreia Raquel Martins Garrido acknowledges the financial support provided by national funds through FCT - Portuguese Foundation for Science and Technology (PD/BD/128275/2017), under the Doctoral Programme ‚ÄúAgricultural Production Chains ‚Äď from fork to farm‚ÄĚ (PD/00122/2012) and from the European Social Funds and the Regional Operational Programme Norte 2020.

    The Indian crested porcupine (Hystrix indica) is a vertebrate pest of agricultural lands and forest. The study was aimed to report the damage to local crops by the Indian crested porcupine (Hystrix indica) in the Muzaffarabad District. A survey was conducted to identify the porcupine-affected areas and assess the crop damage to the local farmers in district Muzaffarabad Azad Jammu and Kashmir (AJK) from May 2017 to October 2017. Around 19 villages were surveyed, and a sum of 191 semi-structured questionnaires was distributed among farmers. Crop damage was found highest in village Dhanni where a porcupine destroyed 175 Kg/Kanal of the crops. Regarding the total magnitude of crop loss, village Danna and Koomi kot were the most affected areas. More than half (51.8%) of the respondents in the study area suffered the economic loss within the range of 101-200,and(29.8, and (29.8%) of the people suffered losses in the range of 201-300 annually. Among all crops, maize (Zea mays) was found to be the most damaged crop ranging between 1-300 Kg annually. In the study area, porcupine also inflicted a lot of damages to some important vegetables, including spinach (Spinacia oleracea), potato (Solanum tuberosum) and onion (Allium cepa). It was estimated that, on average, 511Kg of vegetables are destroyed by porcupine every year in the agricultural land of Muzaffarabad. It was concluded that the Indian crested porcupine has a devastating effect on agriculture which is an important source of income and food for the local community. Developing an effective pest control strategy with the help of the local government and the Wildlife department could help the farmers to overcome this problem

    Tese de Doutoramento em Engenharia T√™xtilNa √ļltima d√©cada, a procura de solu√ß√Ķes t√™xteis ecologicamente mais sustent√°veis e com maior funcionalidade para √°reas de aplica√ß√£o t√©cnica cresceu significativamente. Na √°rea da agricultura, as mudan√ßas clim√°ticas e o aumento da popula√ß√£o impulsionaram o desenvolvimento de t√™xteis inovadores, em particular n√£o-tecidos, produzidos com fibras naturais ou biodegrad√°veis, destinados √† gest√£o da √°gua, um dos problemas mais prementes na agricultura atual. Nesta tese o objetivo foi desenvolver um n√£o-tecido √† base de fibras de suma√ļma em rama (designadas neste trabalho como fibras de capoc) e em mistura de fibras de suma√ļma e linho, capaz de recolher √°gua proveniente da condensa√ß√£o de infiltra√ß√Ķes no solo e evapotranspira√ß√£o das plantas, para possibilitar a sua utiliza√ß√£o na rega. Como as fibras capoc s√£o curtas e com baixa resist√™ncia mec√Ęnica, a cria√ß√£o de estruturas n√£o tecidas com o desempenho requerido, constituiu um dos maiores desafios e conduziu ao estabelecimento de um m√©todo de produ√ß√£o inovador (pedido de patente nacional n¬ļ 109924 A) que permitiu a produ√ß√£o de n√£o tecidos 100 % capoc com o desempenho funcional requerido para aplica√ß√Ķes em agrot√™xteis. A estrutura base dos n√£o-tecidos foi obtida pelo processo dry-laid (via seca) de forma√ß√£o da manta, usando a linha de n√£o-tecidos "Automatex". Adotaram-se diferentes fluxos de materiais, diferente disposi√ß√£o das fibras e n√ļmero de sobreposi√ß√Ķes (camadas). A consolida√ß√£o da manta foi efetuada utilizando o m√©todo tradicional de agulhagem e o novo m√©todo de produ√ß√£o, que inclui prensagem, resultando em estruturas n√£o-tecidas formadas unicamente por capoc e por misturas de capoclinho, denominadas como n√£o-tecido simples, sandwich e compostos. Os n√£o-tecidos produzidos foram caracterizados relativamente √†s suas propriedades geom√©tricas e estruturais, propriedades mec√Ęnicas (tra√ß√£o e pun√ß√£o), propriedades t√©rmicas, transfer√™ncia de ar, capacidade de dispers√£o e absor√ß√£o de √°gua. Os n√£o-tecidos 100% capoc foram expostos a envelhecimento acelerado (QUV), sendo posteriormente analisados qu√≠mica e estruturalmente (por espectroscopia de infravermelhos e calorimetria diferencial de varrimento) e avaliadas as suas propriedades mec√Ęnicas (tra√ß√£o e pun√ß√£o) e capacidade de molhagem (√Ęngulo de contacto). O efeito da radia√ß√£o UV e da condensa√ß√£o no aumento da espessura e capta√ß√£o de √°gua do n√£otecido tamb√©m foi avaliado. Os n√£o-tecidos 100 % capoc desenvolvidos demonstraram ser super-hidrof√≥bicos, com √Ęngulos de contacto variando entre 160¬į e 180¬į, com resist√™ncia √† rotura atingindo cerca de 900 N e resist√™ncia √† perfura√ß√£o acima de 150 N. Estes n√£o-tecidos, com espessuras muito pequenas, apresentaram boas propriedades t√©rmicas, com resist√™ncias t√©rmicas situadas entre 148-186 (x10-3) m2KW-1, e uma muito baixa permeabilidade ao ar (inferior a 2 l/m2/s). Os n√£o-tecidos de mistura de capoc-linho desenvolvidos pelo processo convencional atingiram resist√™ncias √† rotura de 600 N e √† perfura√ß√£o de 1400 N, com uma redu√ß√£o da extens√£o do dano em cerca de 30 % devido √† maior densidade aparente destas estruturas. O trabalho de investiga√ß√£o realizado permitiu assim obter estruturas n√£o-tecidas 100 % capoc ou em mistura capoc-linho inovadoras, com o desempenho mec√Ęnico requerido para aplica√ß√Ķes em agrot√™xteis e geot√™xteis, compat√≠vel com os requisitos de geot√™xteis da classe III.In the last decade, the search for more ecological, sustainable and functional textile solutions for technical applications has grown significantly. In the area of agriculture, climate change and population growth have driven the development of innovative textiles, especially nonwovens, produced from natural or biodegradable fibers, for water management, one of the most pressing problems in agriculture current. In this research study, the intention was to develop a nonwoven based on raw kapok fibres and kapok-flax blends, capable of collecting water from the condensation of infiltrations in the soil and the evapotranspiration of plants, to enable its use in irrigation systems. As the kapok fibers are short and with low mechanical resistance, the creation of non-woven structures with the required performance was one of the biggest challenges and led to the establishment of an innovative production method (national patent application n¬ļ 109924 A) that allowed the production of 100 % kapok nonwovens with the functional performance required for application in agrotextiles. The nonwoven base structure was obtained by the dry-laid process of mat formation, using the "Automatex" nonwoven Line. Different material fluxes, different fiber arrangements and number of overlays (layers) were adopted. The consolidation of the mat was carried out by the traditional needle-punching method and by the new production method, which includes pressing, resulting in 100 % kapok and kapok-flax blended nonwoven structures, referred as simple, sandwich and compound nonwovens. The nonwovens produced were characterized regarding their geometric and structural properties, mechanical properties (tensile and puncture strength), thermal properties, air transfer, dispersion capacity and water absorption. The 100% kapok nonwovens were exposed to accelerated aging test (QUV) and subsequently analyzed chemically and structurally (by Infrared Spectroscopy and Differential Scanning Calorimetry). The mechanical properties (tensile and perforation) as well as, wetting capacity (angle of contact) were evaluated. The effect of UV radiation and condensation on nonwovens thickness increase and water collection was also analyzed. The 100% kapok nonwovens developed demonstrated to be super-hydrophobic, with contact angles varying between 160¬į and 180¬į. The tensile strengths obtained were up to 900 N and the puncture resistances above 150 N. These nonwovens, with very small thicknesses, showed good thermal properties, with thermal resistances lying between 148-186 (x10-3) m2KW-1, and extremely low air permeability (lower than 2 l/m2/s). The kapok-flax nonwovens produced by the conventional needle-punching method achieved tensile strengths of 600 N and puncture resistances of 1400 N, with a decrease in the through-thickness damage of around 30%, due to higher bulk density of these structures. This research work allowed the production of novel 100 % kapok and kapok-flax nonwoven structures with the mechanical performance required for agrotextiles and geotextile applications, compatible with class III geotextiles‚Äô requirements
