Cosine Windows in Interpolated DFT-based Method for an Accurate High-Frequency Distortion Assessment in Power Systems
Authors: A. Bracale  , P. Caramia  , G. Carpinelli  , P. De Falco  , P. Verde
Published: June 2023

The transformation of electrical networks in the context of the new smart grid paradigm unavoidably involves new challenges regarding Power Quality (PQ) disturbances not only for customers but also for all the other involved stakeholders. Among PQ disturbances, waveform distortions have recently gained growing interest due to the massive presence of new technologies in distributed energy resources, in modern loads and in advanced smart metering systems. The presence of these devices determines arduous electromagnetic compatibility problems since the current and voltage waveform distortions in smart grids are characterized by spectral components above the traditional 2 kHz frequency limit, in a range extended up to 150 kHz. In this paper, an interpolated DFT-based (IDFT) method, recently proposed in the relevant literature in the field of signal processing, is properly extended for an accurate and fast assessment of power system waveform distortions in the frequency range from 2 to 150 kHz. Since DFT-based methods can suffer well-known spectral leakage problems, in this paper the IDFT is applied using cosine windows that minimize interference conditions among spectral components and maximise the estimation accuracy of the spectral component amplitude, phase angle and frequency. An optimal number of cosine window terms is also searched to improve the spectral analysis of high-frequency power system waveforms. Numerical applications on synthetic test signals and measured waveforms are carried out to quantify the accuracy and computational efforts of the proposed approach and to select the cosine window terms that better optimize the waveform distortion assessment.

This study aims to present the results of the application of a computational tool developed to perform a technical-economic feasibility analysis of large-scale Parabolic Trough Collectors (PTC) solar power plants in Brazil. The gross revenue from cash flow is obtained through an energy trading model for the Regulated Contracting Environment of the Brazilian Electricity Market. The economic viability analysis uses the Net Present Value, Modified Internal Rate of Return, Discounted Payback, and Levelized Cost of Energy indicators. The parametric structural optimization method is used to optimize the technical parameters of the plant. A case study was conducted to analyse the feasibility of implementing a 100 MW PTC in the five regions of Brazil. The results indicated that the best region in Brazil to receive this technology is the northeastern region. However, the project is economically unfeasible in all cities analysed. Therefore, a sensitivity analysis of the main parameters that affect the project's net present value is carried out to evaluate the impact of the economic parameters on the economic viability of an optimized PTC plant located in the city with the best technical performance. An optimistic scenario was evaluated considering the system's response to the parameters investigated in the sensitivity analysis. For this scenario, the results pointed to the project's economic viability.

Published: June 2023

Wind/Photovoltaic energy systems are among the most used configurations in multi-sources energy systems because their reliability, robustness and power sources complementarily. For heavy loads, it is more convenient to add backup systems (diesel generator) for an enhanced power availability. In order to protect power sources and increase their lifespan, several power management strategies are such as fuzzy logic control, artificial neural networks and metaheuristic algorithms are proposed and used in literature. This paper presents a power supervisory control (PMC) based on fuzzy logic control dedicated for photovoltaic/wind turbine/ diesel generator/battery systems. The application of the aforementioned technique makes it possible to predict how the hybrid system various operating processes would change in response to solar irradiation and wind speed variations. The study was implemented under Matlab/Simulink. To obtain more realistic results, measured weather values have been incorporated in the simulation. The application is made in a coastal town which has a good potential values of solar irradiance and wind speeds. The obtained results show that the load have been supplied while the batteries were protected due to the PMC.

Published: June 2023

Initiatives have been launched by the EU to address climate change, including those aimed at islands and municipalities. Analysing the impact of the energy transition through modelling is essential for the strategic decision-making process to move forward to the ET.The new energy model requires municipalities to be key drivers, although their needs are very specific and depend on external factors such as their own governance. In the case of municipalities located on tourist islands, the need for tools and support for the creation of energy and sustainable transition plans is even more evident. Currently, methods and models have been developed for energy planning or for the assessment of different energy scenarios, but there is no model that integrates a multidimensional approach at the municipal level, enhancesthe decisions of policymakers, integrates a knowledge base specifically focused on islands and monitors the progress of local measures through energy indicators.This paper reviews the state of existing decision-makingmodels and energy tools, specifically those aimed at islands and policymakers, and identifies the gaps to generate added value to facilitate the path to ET for island tourist municipalities and monitor their progress.

Authors:   Department of Electrical Power Engineering University of West Bohemia, Plzen  Czech Republic, Belik Milan
Published: June 2023

The paper deals with optimisation of energy storage systems technology for emergency shelters (tiny houses) for Ukrainian War refugees. Huge number of Ukrainian citizens lost their houses or had to leave their homes. These refugees increase population in the rest of Ukraine what escalates problems with accommodation and integration into native communities. Emergency living in communal properties has unpleasant influence on the communities and is acceptable just for limited period. It becomes important to build new quarters or urban areas using cheap but energy efficient technologies. This research is based on real shelter project realised between Ukrainian non-government organisation Synergy and German development agency weChange. Main task of this paper is optimisation of energy strategy in community consisting of hundreds or thousands units and called shelter city. Solution of one single tiny house with implemented RES is task deeply evaluated in several projects, but we must take into account cooperation of large amount of units to limit total influence on Ukrainian distribution and transmission networks. Ukrainian infrastructure was already in unpleasant state before war and new connections of these consumers would dramatically overload existing infrastructure. This task is yet more complicated in nowadays war conditions, where crucial parts of the networks are being repeatedly damaged. From this point of view, it is essential to design the shelter community like consumer o prosumer with perfectly balanced load and production chart. The shelters should be built in passive standard to achieve minimal acquisition and operational costs. Also very efficient but cheap energy storage system must be integrated on the level of particular shelter or entire shelter city. Influence of various battery technologies using different coupling schemes is being discussed. AC coupling, DC coupling with intermediate circuit or PV generator circuit are tuned for specific load charts to optimise the influence on distribution network.

Authors: A. Jakoplić  , S. Vlahinić  , B. Dobraš  , D. Franković
Published: June 2023

Recently, the share of renewable sources in the energy mix of production units has been steadily increasing. The unpredictability of renewable sources leads to difficulties in planning, managing and controlling the electric energy system (EES). One of the ways to reduce the negative impact of unpredictable renewable sources is to predict the availability of these energy sources. Short-term forecasting of photovoltaic power plant production is one of the tools that enable greater integration of renewable energy sources into the EES. One way to gather information for the short-term forecast production model is to continuously photograph the hemisphere above the photovoltaic power plant. By processing the data contained within the images, parameters related to the current output power of the observed power plant are obtained. This paper presents a model that utilises a convolutional neural network to analyse images of the hemispherical sky above a power plant to predict the current output power of the power plant. Estimating current production is a crucial step in developing models for short-term solar forecasts. The model was specifically developed for photovoltaic power plants and is capable of achieving high accuracy in power prediction. The estimation of power production from photovoltaic power plants enables the use of next-frame prediction for short-term forecasting.
Reducing Fossil Fuel Consumption by Incorporating Renewable Energy Sources in Wastewater Treatment Processes
Authors: Hen Friman
Published: June 2023

Various types of aqueous solutions are disposed of in residential, institutional, commercial, and industrial buildings. The wastewater must be treated to remove pathogens (bacteria, viruses), nutrients (nitrogen, phosphorus), and other compounds in order to maintain public health and the environment. Accumulation of untreated sewage can result in a wide range of nuisances. Most of Israel's wastewater is purified and used for irrigation every year, which amounts to 530 million cubic meters. Approximately 80 percent of wastewater recovered in Israel is recycled. By treating wastewater appropriately, agriculture, tourism, gardening, and industry can benefit. The presence of raw sewage in settlements with no sewage collection or transportation networks continues to pose a great threat even today. There is a significant energy consumption associated with wastewater treatment processes. In this study, solar energy was attempted to be integrated as a renewable energy source. With Renewable Energy Sources integrated into the process, costs will be reduced, and it will also be possible to establish decentralized facilities in areas without proper infrastructure for traditional treatment methods.

Published: June 2023

Uncontrolled seepage through earth-fill dams may cause of dam failure. Seepage analysis, therefore, is an essential study required before construction for a safe and sustainable dam operation. In this study, numerical analysis of seepage through a theoretical case of an earth-fill dam was applied using SEEP/W program. Five different dam models, two with homogenous and three with zoned cross sections, have been studied. The study consists normal and maximum reservoir water levels, different drainage lengths and thicknesses, different percentages of permeability between shell and core. Total of 26 tests were conducted and the best model based on seepage behavior was chosen. Seepage analysis acknowledged that with availability of required soil quantity, the homogeneous model that has medium length of drainage with thickness of 0.5 m is the most appropriate model for the case study. Otherwise, zoned model with core at the centre with 1:0.5 (H:V) slope is recommended

Published: June 2023

Today's academic students spend a lot of time indoors, which puts them at risk for psycho-physiological stresses that have a negative impact on their cognition. This study aims to investigate the impact of incorporating biophilic design patterns in the academic environment on student motivation and to develop a verification tool that helps to design and evaluate educational buildings in terms of providing motivating learning environments in accordance with the biophilia hypothesis. The developed verification tool will be applied later to one of Eastern Mediterranean University's buildings in Northern Cyprus. To conduct the present study, a qualitative research method based on a case study analysis is adopted. Literature review for books, scholarly articles, and other sources relevant to the study issue is used, to understand the psychological impacts of incorporating the Biophilic Design patterns in an Educational environment on students’ psychological health. Biophilic design indicators are extracted from a set of existing biophilic buildings in order to set the verification tool. The verification reveals that the case study featured nine biophilic design patterns, which have a positive impact on the learning process.

Authors:   College of Engineering-University of Mosul-Iraq, Abdulmawjoud Ayman , Shamam Amina , Younis Noor
Published: June 2023

One of the most important infrastructures for any country is the road system. The main cause of the accelerated deterioration of flexible pavement on Iraqi roads is overloaded vehicles, which can lead to the failure of asphalt roads. As a result, two types of asphalt road failure that need to be taken seriously are fatigue and rutting. The study's objective is to use the Mechanistic-Empirical Method (M-E) to identify fatigue and rutting failures by employing (KENLAYER) program to analyze flexible pavement performance at different axle loading. Assuming that the pavement structures form a linear multi-layer structure for flexible pavement, and that their mechanical responses depend on temperature and loading, HMA layers behave as viscoelastic materials in real-world settings, and the granular layers behave as nonlinear materials. According to Iraqi axial load requirements, the axle load were applied at proportions of 50%, 100%, 150%, and 200% of the Iraqi standard. The findings showed that the asphalt stabilized base course of the single axle experienced the highest tensile strain values among the layers (1.5*10-4) for the standard load, while the top of the subbase layer of the single axle with dual tires experienced the highest compressive strain values (4.761*10-4) for the standard load. It was also observed that the increasing of axle loads produces an increase in the vertical displacement of the pavement. Where the deformation value on the wearing layer of the tandem axle is (0.8998 mm) for standard load, and that 74% of this deformation was in the subgrade layer. The asphalt stabilized base course had the highest damage ratio with a value of (0.04426) at standard load. Additionally, it was revealed that increasing the load twice the standard load results in a 9 times reduction in design life, which lowers paving efficiency.

Published: June 2023

A large proportion of the data created during the inspection and assessment of stone facades and their damages is recorded in formats that are not machine-readable and thus cannot be further processed or managed digitally. Consequently, this increases the risk of data loss and incorrect information due to human misinterpretation. Therefore, a Multimodel-based approach has been developed in which stone facades of existing buildings are digitized as IFC-model by using proxy entities and linked with web ontologies for semantic enrichment. Additionally, detected anomalies in the stone structure are implemented and linked with geometrical representations. By utilizing additional rules and inference mechanisms, the anomalies can be classified, and a knowledge-based damage assessment is processed.

Robust estimation of the undrained cohesion of fine-grained soils is crucial in the routine design of structures in contact with such soils. However, there is no relationship that could be utilized to estimate the undrained cohesion of cohesive soils in the north of Iraq. This research aims to fill this gap in knowledge. 87 undrained samples were collected and tested in the laboratory and the results were then used to develop predictive models using simple regression analysis and multi-objective evolutionary polynomial regression analysis (EPR-MOGA). It has been found that the undrained cohesion is correlated with reasonable accuracy with water content and dry density of the soil with a coefficient of correlation of 0.82 and 0.77, respectively. Furthermore, poor correlation is found to between the undrained cohesion and liquid limit, plasticity index, and over-consolidation ratio with a coefficient of correlation ranges between 0.30 and 0.36. In addition, it has been noticed that the use of the EPR-MOGA improves the accuracy as it increased R to 0.86. The developed correlations could be used in estimating the undrained cohesion for cases where it is not possible to do the unconfined compressive strength test.

Published: June 2023

Teachers as well as pupils may experience stress during the process of teaching and learning a second language in a classroom setting. Mindfulness-Based Interventions are an effective way to manage stress issues in language classrooms. This study aimed to explore the perception of selected English as a Second Language (ESL) teachers on implementing MBIs during their online lessons regarding their understanding of and challenges in its execution. The perceptions of Malaysian English language teachers of this intervention have not been adequately evaluated, despite being one of the most important stakeholders in academia. Seventeen English language instructors from two secondary schools in Perak were interviewed using a semi-structured format. The subjects were chosen using a convenient sampling method. The goal was to determine what the teachers thought about the intervention in general. In addition, their readiness and acceptance of the method are also investigated. The interview was also conducted to elicit their thoughts on the potential inhibitors and facilitators to the introduction of MBIs in their lessons. The findings indicate that the idea of mindfulness is still new to the teachers since they do not understand it collectively. The challenges associated with executing the plan are also emphasized, along with recommendations for mitigating them. Despite possible obstacles, the teachers exhibit a generally positive attitude and a strong desire to implement Mindfulness-based Interventions in their classrooms.

Authors: Lahlou Hicham , Abdul Rahim Hajar
Published: June 2023

Despite the large number of studies conducted on polysemy, they mostly compare the different methods and techniques to learn a language and establish the extent to which particular sense relations facilitate the learning of second language vocabulary. To our best knowledge, no research has been conducted to determine whether or not polysemy is emphasized in non-native English textbooks. The objective of the present research was to determine the degree to which polysemy is incorporated in English textbooks. Thus, the research question guiding the current study is: To what extent is polysemy incorporated in non-native English textbooks? The study is a corpus-based research that used a data set of 500 words, i.e., 250 words from each of the two books, utilizing the Sketch Engine word list tool and concordance. The polysemy of the resulting words in the concordance lines generated was semantically annotated manually using WordNet and English dictionaries. The results indicated that polysemy is barely stressed in the textbooks under investigation. The study’s results have substantial implications for polysemy in particular and second or foreign language teaching in general

The study attempted to explore Saudi English learners’ second language proficiency and how it is possibly related to language learning strategies and cultural intelligence. Research questions addressed the variables of language proficiency, cultural intelligence, strategy use, gender, and educational school background. It is hoped that more insights into the interplay between these factors and successful language learning will benefit language learners, teachers, and policymakers. The study collected data from 180 Saudifirst-year undergraduates majoring in English. The data was analyzed using inferential statistics to investigate the relationship among the study variables. The results revealed that the study participants scored a medium level in both language learning strategies and cultural intelligence. Metacognitive and cognitive strategies were the most frequently used, and affective strategies were the least frequently used. No significant differences were found in strategy use when related to English language proficiency, gender, or school background. However, a significant effect was observed between language level and cultural intelligence, specifically on metacognitive, and behavioral subsections. Another positive correlation was reported between strategy use and cultural intelligence, especially with the metacognitive subsections. Pedagogical implications are presented as the study argues for the benefits of direct instruction on cultural awareness and strategy use in language classrooms.

Authors: E. Alanazi Shatha , N. Alsager Haroon
Published: June 2023

English is the primary second language learned in Saudi Arabia. Many Saudi students are learning English as a second language for several reasons. Still, almost all English second language learners in Saudi Arabia are willing to learn English proficiently as English natives. Chomsky’s Universal Grammar is one of the primary theories that has discussed the idea of learning a second language. The primary purpose of this study is to develop an understanding of the role of Universal Grammar in second language acquisition by investigating how Saudi Learners of English use the English Adjective Phrase Structure. This research adopts the Full Transfer/Full Access Model as its model. This study used an online questionnaire method design and both quantitative and qualitative approaches to analyze data. This study assigned 118 participants from undergraduate students in Level Two and Level Five at English Language and Literature Department at Prince Sattam bin Abdul-Aziz University. The primary findings of this study indicate that native-like proficiency can be reached due to the fact there is full access to Universal Grammar when learning a second language. This study also found that Arabic as a first language plays a significant role in the beginning stages of learning English as a second language. Furthermore, the findings reveal that the effect of the first language on the second language can be overcome with more input the learner gets.

This study aims to find out how the woven sarong business is sustainablein Samarinda by looking at how innovation is, as well as the obstacles encounteredwhile running the business. This study uses descriptive qualitative research, bycollecting data through interviews with craftsmen or business owners of Samarindawoven sarongs. Data analysis techniques use data reduction, data display, anddrawing and verifying conclusions. Based on the results of interviews, it is knownthat the innovation of woven sarong craftsmen in the city of Samarinda is minimal.Products are only based on customer orders, especially in the production of clothing types. Product innovation is also influenced by circumstances such as the creation of woven masks. The most prominent innovation is related to design innovation, where craftsmen use trending young colors, this gets a positive response from customers. The constraints faced by craftsmen related to the production process are labor, health, time and weather and threads that often break. Barriers in terms of marketing are relatively minimal due to the lack of understanding of the craftsmen about the importance of marketing and the background of the existence of regular customers or resellers so that the craftsmen cannot be deceived. Craftsmen are expected to be even more innovative in terms of product design and novelty so that their businesses can grow and absorb labor and utilize technology as a marketingmedium.Keywords: Innovation, Marketing, SME, Weaving Sarong Craftsmen.

In order to adapt the organization and functioning of the educational system to the constitutional requirements derived from the document of 1978, the Spanish educational reform of the 1980s and 90s went beyond the national borders encompassing international spaces. In its broad and firm expansion to different countries of the Latin American orbit, we want to show how it had a special impact on the reform of the Brazilian education agreed in the nineties reflecting on its development, especially, in the PCNs (National Curricular Parameters). We approach this analysis, derived from the application of the Systematic Literature Review method, which we anticipate of high value and interest, from a threefold dimension that seeks to investigate the influences of Spanish educational policies on Brazil. Firstly, we make use of the essential and classic contribution on school culture made by Professor Escolano (2000). Secondly, we advance until we approach curriculum design (what we understand as“the discourse”) and its consequent projection. And finally, thirdly, we analyze the tensions between psychologists and pedagogues both in interpretative and academic terms that were illustrated in conferences, congresses, seminars and, of course, in the publication of books, articles and reports.

A excelência académica entorpecida
Authors:   Universidade Portucalense Infante D. Henrique, Borges Germano , Torres Leonor Lima ,   Universidade do Minho
Published: June 2023

A versão elitista da excelência académica que tem vindo a predominar no sistema educativo é aquela que a define como um desempenho excecional, uma qualidade distintiva de poucos que transcendem a norma da performance satisfatória, associada à ideia de que os estudantes reconhecidos por mérito escolar e integrados em “Quadros de Excelência” situam-se à margem de descontinuidades escolares, na lógica de uma excelência para memória futura. A visão romantizada do ideal performativo tem vindo a produzir efeitos nebulosos nas trajetórias estudantis, exacerbando a pressão naqueles que aspiram manter-se no patamar da excelência. Este artigo pretende analisar o percurso académico e a transição para o ensino superior dos “melhores alunos” dos cursos científico-humanísticos da escola pública portuguesa. Enquadrado numa pesquisa de doutoramento que envolveu mais de 400 estudantes, este artigo centra-se na análise das classificações no ensino superior de 142 destes alunos e de depoimentos em inquérito por questionário e entrevista. Os resultados evidenciam os efeitos de uma narrativa unidimensional da excelência, fortemente sustentada em lógicas “resultadistas”, com a excelência conquistada a revelar-se temporária e desfasada dos padrões de excelência exigidos no ensino superior.
La filiation à l’épreuve du handicap
Authors:   Université Paris, Zoungrana Laurent
Published: June 2023

Si de nos jours les évolutions législatives et sociétales sont en faveur des personnes en situation de handicap, dans les faits certaines representations negatives persistent. Les traumatismes en liens avec leur vie relationnelle, affective et sexuelle causés dans le passé peuvent demeurer également au point d’anéantir toute chance de réparation. Ainsi, l’expérience singulière de Leslie aujourd’hui âgée d’une trentaine d’années et de sa mère de laquelle elle a été séparée dès la naissance est un exemple parmi tant d’autres. Entre honte et culpabilité, disqualification et «meurtre symbolique», cette mère et sa fille ont subi des violences physiques, morales et psychiques du fait de cette séparation qui leur a été impose. Victimes toutes deux de discrimination au nom du handicap de la mère, elles en payent encore aujourd’hui les conséquences. Peu nombreux sont ceux qui croient aux capacités et compétences des personnes en situation de handicap, surtout mental à élever un enfant. De fait, le désir de procréation et de parentalité ne leur est pas automatiquement reconnu, même si aucun texte ne l’interdit. Il faut que soit prise en compte la parole de ces personnes et qu’elles soient associées à toutes les prises de décisions les concernant car la promotion de la personne, la rendre aussi responsable c’est socialement valorisant. Au-delà du statut de personne en situation de handicap il y a un être humain, un sujet.
Democracia en la escuela: concepciones de estudiantes de contextos desafiantes y favorables
Authors:   Universidade Autónoma de Madrid, Moreno-Medina Irene
Published: June 2023

El objetivo de este estudio es conocer las concepciones de los estudiantes de centros educativos situados en contextos socioeconómicamente desafiantes y en entornos favorables sobre la democracia y su ejercicio en la escuela. Para alcanzarlo, se realizó una investigación fenomenográfica en el que participaron 30 estudiantes: 15 de escuelas situadas en contextos favorables y 15 de escuelas situadas en contextos desafiantes. Los resultados indican que existen cinco concepciones sobre la democracia en la escuela. Estas cinco concepciones nos muestran lasdiferencias y similitudes según el contexto de los estudiantes, demostrando cómo las condiciones del entorno influyen en la comprensión y el ejercicio de la democracia en el alumnado. Las concepciones se manifiestan linealmente, siendo una primera concepción puramente delegativa hasta llegar a una última en el que la representación y la participación se pone de manifiesto de forma crítica. La promoción de esta última concepción es esencial para fomentar entre los estudiantes el pensamiento reflexivo para que se conviertan en ciudadanos y ciudadanas que velen por una sociedad justa, equitativa y democrática.
John Dewey e Paulo Freire: educação e transformação social
Authors:   Universidade estadual de Londrina, Muraro Darcísio N.
Published: June 2023

O objetivo deste artigo é desenvolver a seguinte problemática: em que bases o conceito de experiência contribui para pensar uma educação voltada para a transformação social na perspectiva de Dewey e Freire? O objetivo do estudo é analisar os conceitos de experiência, diálogo e educação no pensamento de Dewey e Freire. A metodologia da pesquisa é qualitativa de caráter bibliográfico, centrada nos procedimentos de análise filosófica dos conceitos mencionados no objetivo deste estudo. Para os autores em estudo, a filosofia e a educação não podem ficar alheias aos problemas que afetam e empobrecem a experiência humana historicamente situada. A experiência está ameaçada pelas forças autoritárias, negacionistas, antidialógica e excludentes favorecendo os interesses neoliberais. Como resultado a pesquisa considera que a educação como modo de vida democrático de compartilhamento da experiência pelo diálogo, reflexão, problematização e busca de objetivos comuns se constitui na alternativa para a transformação social na perspectiva libertadora e humanizadora. Experiência dialógica é prática ética e política da educação na transformação do mundo. Ela torna possível a experiência democrática como prática da liberdade, da capacidade de decidir e da autodeterminação dos sujeitos na construção da história.

O presente trabalho pretende descrever o processo de elaboração do primeiro currículo do Mestrado em Ciências de Nutrição no modelo de aprendizagem baseado em problemas (PBL) na Universidade Eduardo Mondlane. Argumenta-se que, embora seja complexo e exigente, a elaboração e implementação do currículo no modelo PBL, se afiguram necessárias e adequadas para minimizar problemas reais de alimentação e nutrição que afectam o quotidiano da população moçambicana. A elaboração do currículo teve a duração de dois anos e recorreu a métodos participativos que envolveram onze docentes de sete faculdades da Universidade Eduardo Mondlane, realização de consultas aos stakeholders, capacitação da comissão de desenvolvimento do currículo, participação em workshops, reuniões virtuais alargadas e encontros presenciais em pequenos grupos. Foram entrevistados 90 stakeholders de diferentes instituições, exercício que permitiu a definição do perfil profissional ideal para os mestres em ciências de nutrição no país. As reuniões virtuais, com facilitadores das Universidades de Maastricht e de Wageningen, ambas do Reino dos Países Baixos, resultaram na aquisição de conhecimento e habilidades necessários para o desenho do currículo e posterior implementação nos termos do modelo de aprendizagem baseado em problemas. As reuniões presenciais em pequenos grupos serviram para discussão e concertação de ideias que se afiguraram cruciais para os módulos que estavam a ser desenhados. Finalmente, os workshops permitiram um intenso trabalho que culminou com a elaboração integral do currículo e subsequente aprovação pelos órgãos colegiais da Universidade Eduardo Mondlane.
