Almond is highly produced in the NE of Portugal, where late frosts during flowering, low precipitation, and high tempera- ture in summer affect productivity and quality. Despite the use of late-flowering cultivars, plant biostimulants (PBs) and boron-based fertilizers can also be used to improve cell division, vegetative growth, photoassimilates rate, and nutritional status. PBs are widely used in some food crops, but the evaluation of their effects is still scarce. We treated three-year- old almond trees of cv. ‘Vairo,’ growing in a rainfed orchard in the NE of Portugal, with four individual treatments: two PBs (based on seaweed extract and free amino acids) and two boron-based fertilizers (applied on soil and leaves). Three monthly applications of seaweed extract (AN), free amino acids (AA), and boron ethanolamine (BE) were made. A single application of boron on the soil (BS) was made. Leaf samples were collected in treated and untreated (control) trees in cytogenetic and molecular analyses through the summer of 2019. The mitotic cell cycle analysis was performed to prepare mesophyll dividing cells stained with silver nitrate, and the molecular stability was assessed with five marker systems. This work aimed to extrapolate which individual treatment conferred higher mitotic cell cycle regularity and molecular stability. The cytogenetic and molecular data achieved in the cv. ‘Vairo,’ under the edaphoclimatic conditions studied, revealed that the individual treatments AA, BE, or BS induced higher leaf mitotic indexes, regular mitosis, and molecular stability, which might increase the photosynthetic area and production.

With the energy crisis and the constant blackout in the Mozambique Power Company grid, the option of applying solar photovoltaic (PV) systems has been one of the most used alternatives in the neighborhoods of the Maputo region. However, inefficient power delivery caused by unproper sizing and installation of stand-alone solar PV systems has been contributing to the low utilization of solar energy potential in the Maputo region. The optimal sizing and installation of the solar PV system is addressed to evaluate the influence of installation and operation parameters on the power output of PV modules. In this topic, PV modules parameters such as cell temperature, the module’s slope and azimuth angles, the losses caused by excessive heating of the module cells, shadows and dust on the PV module and the cooling process at the back of the module are assessed in order to find out the consequence of inadequate installation and operation parameters of solar PV systems in the Maputo region. The proper sizing and installation of the stand-alone solar PV system is fundamental to guarantee the continuous and efficient supply of power and, thus, different tools and techniques have been applied. This study will deal with the hybrid optimization of multiple energy resources (HOMER) and system advisor model (SAM), to size and improve power generation of solar PV systems. This study concluded that for the Maputo region, the optimal tilt angle is 23 ± 2° and the azimuth angle is 11 ± 2°. In addition, for optimization of the tilt and azimuth angles, it also examined the effect of module backside ventilation and proved that the system’s power generation increases with the rise of spacing between the module and the wall, since the strategy prevents the decline of the module cells efficiency. However, the maximum recommended spacing between the PV module and the mounting wall is about 0.4 m, since an effort to increase the spacing up to this level results in an insignificant growth of power output.

District of Namaacha in Maputo Province of Mozambique presents a high wind potential, with an average wind speed of around 7.5 m/s and huge open fields that are favourable to the installation of wind farms. However, in order to make better use of the wind potential, it is necessary to evaluate the operating conditions of the turbines and guide the independent power producers (IPPs) on how to efficiently use wind power. The investigation of the wind farm operating conditions is justified by the fact that the implementation of wind power systems is quite expensive, and therefore, it is imperative to find alternatives to reduce power losses and improve energy production. Taking into account the power needs in Mozambique, this project applied hybrid optimisation of multiple energy resources (HOMER) to size the capacity of the wind farm and the number of turbines that guarantee an adequate supply of power. Moreover, considering the topographic conditions of the site and the operational parameters of the turbines, the system advisor model (SAM) was applied to evaluate the performance of the Vestas V82-1.65 horizontal axis turbines and the system’s power output as a result of the wake effect. For any wind farm, it is evident that wind turbines’ wake effects significantly reduce the performance of wind farms. The paper seeks to design and examine the proper layout for practical placements of wind generators. Firstly, a survey on the Namaacha’s electricity demand was carried out in order to obtain the district’s daily load profile required to size the wind farm’s capacity. Secondly, with the previous knowledge that the operation of wind farms is affected by wake losses, different wake effect models applied by SAM were examined and the Eddy–Viscosity model was selected to perform the analysis. Three distinct layouts result from SAM optimisation, and the best one is recommended for wind turbines installation for maximising wind to energy generation. Although it is understood that the wake effect occurs on any wind farm, it is observed that wake losses can be minimised through the proper design of the wind generators’ placement layout. Therefore, any wind farm project should, from its layout, examine the optimal wind farm arrangement, which will depend on the wind speed, wind direction, turbine hub height, and other topographical characteristics of the area. In that context, considering the topographic and climate features of Mozambique, the study brings novelty in the way wind farms should be placed in the district and wake losses minimised. The study is based on a real assumption that the project can be implemented in the district, and thus, considering the wind farm’s capacity, the district’s energy needs could be met. The optimal transversal and longitudinal distances between turbines recommended are 8Do and 10Do, respectively, arranged according to layout 1, with wake losses of about 1.7%, land utilisation of about 6.46 Km2, and power output estimated at 71.844 GWh per year.

Esta pesquisa tem por objetivo compreender o campo de interação da produção cultural no Mercosul, a partir do qual os pequenos e médios produtores atuam para viabilizar os seus produtos e serviços culturais. Para isso, a metodologia adotada foi de natureza qualitativa, composta pelas estratégias de pesquisa bibliográfica e documental, aplicação de formulário survey, entrevista e estudo de caso, com finalidade descritiva e analítico-interpretativa. O primeiro capítulo tratou das mudanças e continuidades entre quatro conceitos: indústria cultural, indústrias culturais, indústrias criativas e economia criativa. A partir disso, o segundo capítulo discutiu como os Estados e as instituições supranacionais construíram os discursos da política cultural internacional por meio da associação entre cultura, criatividade e processos de desenvolvimento econômico e cultural. Em complemento, debateu brevemente as implicações dos regimes de regulação do comércio internacional para as políticas culturais. O terceiro capítulo foi dedicado à análise da institucionalização do que denominamos de discurso criatividade e desenvolvimento, tanto nas políticas culturais nacionais como no próprio Mercosul. Em seguida, empreendeu-se a avaliação do modelo de desenvolvimento do Mercado de Indústrias Culturais do Sul (Micsul). Os resultados finais sugerem avanços na última década, mas, na participação global, a posição da região é preocupante. Além disso, observou-se que o campo de interação do Mercosul oferece obstáculos consideráveis e um ambiente pouco favorável aos pequenos e médios produtores culturais. Entretanto, também se notou a marcante resiliência no Micsul e no Mercosul Cultural, isto é, a capacidade de manter uma agenda propositiva mesmo em contextos de crises política e econômica. This work intends to understand the field of interaction of cultural production that occurs within the Mercosur, focusing on small and medium-sized producers who provide cultural services and products. The methodology used to do so was qualitative in nature, composed by bibliographic and documentary research, surveys, interviews, and case studies, with a descriptive, analytical and interpretive purpose. The first chapter addresses the changes and continuity that have occurred among four concepts: cultural industry, cultural industries, creative industries, and creative economy. Based on these findings, chapter two discusses how States and supranational institutions constructed their discourses about international cultural policies through the association of culture, creativity, and economic and cultural development. Additionally, the second chapter briefiy debates the implications of international trade regulations on cultural policies. The third chapter analyzes the institutionalization of the so called creativity and development discourse, found in national cultural policies as well as in the Mercosur itself. Next, the model of development of the MICSUL (Cultural Industry Market of the South) was evaluated. The final results suggest progress throughout the past decade, however, when analyzed in a global setting, the region\'s position is greatly concerning. Furthermore, the field of interaction observed in the Mercosur exhibits significant obstacles and an unfavorable setting for small and medium-size cultural producers. However, exceptional resilience was observed at both the MICSUL and Cultural Mercosur, that is, the ability to maintain a purposeful agenda even when facing political and economic crisis.

The knowledge of the chemical composition of the Salicornia ramosissima halophyte is crucial to ascertain the value of this under-exploited resource. Hence, it is the purpose of this study to analyse the nutrient composition of S. ramosissima collected in the Mondego estuary, Portugal, in July and November of 2019. On a dry weight (dw) basis, S. ramosissima consisted of 47.4 % ash, 10.4 % crude fibre, 4.16 % protein and 0.450 % lipids. Given its importance, particular emphasis was placed on the mineral fraction, which was evaluated through a “green” method based on ultrasound-assisted extraction with water, followed by potentiometric and colorimetric determination using a chemical auto-analyser. The predominant minerals analysed and their respective content were sodium 159, magnesium 9.01, potassium 7.22 and calcium 2.99 mg/g dw. This clean methodology proved to be sound, achieving good results for recovery (80.5–108 %) and repeatability (% RSDr ≤ 4.81 %). Owing to its high fibre content and mineral richness, S. ramosissima showed remarkable potential as a functional ingredient.

The purpose of this chapter is to identify and analyze the main organizational and technological factors that play a relevant role in a transformational strategic change inherent in changing the business model supported on the internet. An analysis was made of the different business models, as well as their connection to strategic management and how this is accomplished in the organizational and technological plan. This empirical study, based on the qualitative methodology, focuses on a single case study on a Portuguese company that recently changed its business model. The findings allowed the authors to assess the advantages and challenges posed by the transformation of an initial business based on a website that performs a comparison of prices for an integrated model based on a marketplace, in which customers can make their purchases and access all products, from different stores, in one place.

The main attributes of Supply Chain (SC) operations within AbbVie, a global pharmaceutical company, are presented, as well as the key factors for risk mitigation within the deliverance of AbbVie products and services are introduced.

At AbbVie, the Sales and Operations Planning (S&OP) and demand forecasting are jointly addressed, being the S&OP involvement, the key elements within S&OP, and the global S&OP process contributing all together for the successful prevention of medicines shortages. In this way, Key Performance Indicators (KPI) were defined to adequately measure AbbVie performance, and SC operations are evaluated through the customer satisfaction, the operational excellence, and the assurance of supply during a three-years period.

Energy consumption in South Africa (SA) has been increasing significantly in the last decade due to industrialization and growth of households countrywide. In the attempt of increasing power generation, the SA government has been adopting the policy of generating electricity from renewable energy sources and encouraging the emerging of independent power production (IPP) initiatives. However, despite all those efforts, the dream 100% of renewable energy technologies implementation in SA has been slowed down due to technical, socio-economic and environmental challenges. As it is known, all power generation technologies have strengths and weaknesses and renewable energy technologies are not exception. In SA, the integration of wind power in the power system is now an unavoidable issue in order to optimize the utilization of the resource and increase the rates of wind technology installation, which is necessary in order to achieve the goals of sustainability and security of supply [5]. In that context, this research on wind energy technology aims to assess wind power technology's main weakness, to discuss the role of society's distinct segments and disciplines on the wind technology improvement and implementation and to contribute to the achievement of 100% renewable energy technology in South Africa and worldwide.

The Daily load shape has an intrinsic correlation with power dispatch and therefore, during the peak demand hours power systems need to operate on their maximum capacity. This paper describes how daily load profile of power systems interacts with power dispatch, driving the supply side to act in accordance with the trend in electricity demand of the consumers. The load curve has a strong dependence with the attitude of the power system customers and other economic services linked with the power system. Peak demand fluctuations may follow a daily, weekly, monthly or annual cycle and thus a distinct power system has its specific daily load curves or different groups of consumers (residential, industrial, commercial etc.) may have similar or individual daily demand curves (John V. Grubbs). Worldwide, traditional power systems are facing gradual shortage of fossil fuel resources, lack of energy efficiency measures and environmental concerns related to CO2 emission. These problems boosted new trends of generating power known as distributed generation [22]. In order to circumvent high fluctuation of electricity demand, different methods can be implemented (energy efficiency, microgrid system, renewable energy technologies etc.). By utilizing microgrids, incorporating renewable and conventional energy sources, electricity can be supplied locally in an economic and environment friendly way [23], reducing the efforts that the main network should do to meet the demand.

Tese de Doutoramento em História da Arte Contemporânea Dentro do quadro da História de Arte Contemporânea, a investigação que agora se apresenta relaciona o papel da arte da dança com o poder, caracterizando os seus diálogos e confrontos ao longo do século XX. Utilizada como veículo de propaganda, a dança tornou-se numa arte politizada e facilmente comprometida com o regime que a enquadrava. O fio condutor do estudo percorre uma viagem balizada entre o momento em que a dança se emancipa do teatro lírico – com o primeiros espectáculos dos Ballets Russes em 1909 – até à comemoração do centenário da Companhia, em 2009, data em que se refletiu extensivamente sobre o universo terpsicoreano contemporâneo. É um século que se configura a partir de uma relação político-artística desenvolvida não só nos regimes autoritários da primeira metade de 1900, mas igualmente presente nos regimes democrático-liberais da última metade do século XX. Posicionando-se a partir de dois vectores distintos – compromisso ou revolta – analisa-se transversalmente o cenário internacional e a produção nacional, cruzando a visão do duplo jogo do poder da dança e da dança do poder e integrando-os nas principais criações produzidas ao longo dos últimos cem anos.

Um homem de 69 anos de idade, caucasiano, foi transferido para a nossa Instituicao Hospitalar com os diagnosticos de aneurisma da aorta ascendente e suspeita de disseccao aguda da aorta, de tipo A. Tinha antecedentes pessoais de hipertensao arterial, irregularmente medicada, diabetes mellitus tipo 2 e habitos tabagicos pregressos (35 UMA). Apresentava queixas de cansaco e dispneia de esforco, com um ano de evolucao e de agravamento progressivo. O atual internamento havia sido motivado por dor toraco-epigastrica com irradiacao ao dorso, acompanhada de dispneia, com um dia de evolucao. Na observacao inicial, o doente encontrava-se hipertenso e salientava-se um sopro diastolico aortico grau iv/vi. As analises e o eletrocardiograma iniciais eram normais. A avaliacao ecocardiografica transtoracica evidenciou marcada dilatacao da raiz da aorta e aorta ascendente (diâmetro transverso maximo: 71 mm), com regurgitacao aortica major associada. Uma imagem duvidosa de flap intimal conduziu a realizacao de um ecocardiograma transesofagico, que confirmou a dilatacao aneurismatica da raiz aortica e aorta ascendente (diâmetro transverso maximo: 71 mm), poupando a crossa e a aorta descendente. A valvula aortica era tricuspide e apresentava regurgitacao grave por ausencia

Two monuments in Portugal are being monitoring by the University of Minho: the Clock Tower of Mogadouro and the Church of Jerónimos Monastery, in Lisbon. Vibration sensors and temperature and relative air humidity sensors are installed in the two monuments. Operational modal analysis is being used to estimate the modal parameters, followed by statistical analysis to evaluate the environmental effects on the dynamic response. The aim is to explore damage assessment in masonry structures at an early stage by vibration signatures as a part of a heath monitoring process to preserve the historical constructions. The paper presents all the preceding dynamic analysis steps before the monitoring task, which includes the installation of the monitoring system, the system identification and subsequent FE model updating analysis, the automatic modal identification and the investigation of the influence of the environment on the identified modal parameters., (undefined)
