- Morotugal - Bilingual Typeface: Bridging Portugal and MoroccoPublication . Lakrizi, Lamya Sefyani; Santos, Ricardo Rodrigues dosThis research attempts to show considerations related to typeface design, specifically for printed materials used to showcase the cultral connections between Morocco and Portugal. Morotugal hybrid typeface will mostly appeal graphically and visually amusing toward a specific target, which are Portuguese and Moroccan dialects speakers. Albeit Portugal being only few miles away from Morocco, it seems that the relationship between the two countries are not often talked about. This is where this research comes in handy. A common typeface is thus needed to describe and showcase not only the diplomatic relations but also the cultural similarity and common words between these nations. This thesis sheds light on methodological techniques while harmonizing and exploring bilingual typefaces. It also investigates different attempts to improve experimentation and blend and homogenize Arabic (Maghribi Mabsut Style) and Latin alphabets, alongside a survey that was conducted to collect large amounts of data to better understand my target audience. The purpose is to explore different legible approaches and create a unified visible typographic identity. Ultimately, the goal is to create a distinct typeface that will showcase and create a visual identity for the bilateralism between Morocco and Portugal, focusing specifically on the common words used in both countries.
- MOTIVOS PARA A PRÁTICA DE EXERCÍCIO FÍSICO, AUTOESTIMA E BEM-ESTAR SUBJETIVO EM MULHERES PORTUGUESASPublication . Silva, Alícia Ribeiro da; Antunes, Raúl de Sousa Nogueira; Monteiro, Diogo Manuel TeixeiraO presente trabalho de investigação foi realizado com o objetivo de caracterizar os motivos para a prática de exercício físico, autoestima e bem-estar subjetivo de mulheres portuguesas, praticantes de ginásio/healthclub. Foram igualmente analisadas as associações entre os motivos para a prática, autoestima e perceção de bem-estar subjetivo na sua dimensão emocional (afeto positivo e negativo). A amostra foi constituída por 206 mulheres, com idades compreendidas entre os 16 e 68 anos de idade. As participantes responderam a um curto questionário sociodemográfico, ao Goal Content for Exercise Questionnaire (GCEQ), à Rosenberg Self-esteem Scale (RSES) e à Positive and Negative Affect Schedule (PANAS). Os resultados mostraram que os motivos de saúde (6.47 ± 0.62) foram os que apresentaram valores mais elevados e demonstraram uma correlação positiva e significativa com a autoestima e afeto positivo, enquanto os motivos de reconhecimento social (2.36 ± 1.38) apresentaram os valores mais baixos e demonstraram uma correlação não significativa com a autoestima e afeto positivo. Paralelamente, os resultados indicaram valores elevados de autoestima (3.98 ± 0.67) e afeto positivo (3.79 ± 0.65) sendo que a autoestima se correlaciona de forma positiva com o afeto positivo e negativamente com o afeto negativo. Este estudo aponta para a necessidade de consciencializar sobre os benefícios da prática regular de exercício físico na saúde física e mental das mulheres portuguesas.
- Refletindo sobre a Prática PedagógicaPublication . Lisboa, Patrícia Raquel do Adro; Menino, Hugo Alexandre Lopes; Santos, Maria João Sousa Pinto dosO presente relatório de Prática de Ensino Supervisionada surge no âmbito do Mestrado em Educação Pré-Escolar e Ensino do 1º Ciclo do Ensino Básico, e encontra-se organizado em duas partes: a dimensão reflexiva e a dimensão investigativa que tem como objetivo principal identificar os estereótipos de género num grupo de crianças do 1º ano de escolaridade. A parte reflexiva relata as reflexões críticas e fundamentadas das aprendizagens mais relevantes que foram realizadas ao longo das Práticas Pedagógicas em contexto de Creche, Jardim de Infância e 1º Ciclo do Ensino Básico. A parte segunda, a dimensão investigativa, apresenta o estudo elaborado durante a Prática Pedagógica do 1º Ciclo I, numa turma do 1º ano. O estudo incide sobre a área da Cidadania, e pretende compreender se existiriam estereótipos de género na turma do 1º ano e se era possível a desconstrução dos mesmos através de um conjunto de atividades. Para atingir esta finalidade, realizaram-se entrevistas iniciais a fim de se identificar os estereótipos existentes, implementouse um conjunto de atividades na tentativa de desconstruir os estereótipos iniciais e, por fim, realizou-se uma entrevista final para compreender se os estereótipos iniciais foram de facto desconstruídos. Para a realização do estudo optou-se por uma metodologia qualitativa, de natureza descritiva e interpretativa, onde participaram seis crianças. Neste sentido, a análise dos dados obtidos revelou que existem efetivamente estereótipos de género por parte das crianças, sendo os rapazes os que mais demonstram estereótipos. Por sua vez, embora as atividades implementadas tenham tido algum impacto, não modificaram de forma significativa os estereótipos apresentados inicialmente.
- Feasibility Study of the PET Fines Incorporation into Recycling ProcessesPublication . Nascimento, Bruna Guilherme do; Bozzola, Fernando; Vasco, Joel C.; Parnigoni, Milena; Capela, Carlos; Heleno, Lizete; Gaspar, Marcelo; Oliveira, Nelson S.Circular economy principles focus on the need to preserve natural resources and foster the use of environmentally sustainable practices. Concerning the use of plastics in a circular economy, increasingly demanding solutions have to be developed towards the zero-waste goal sought after by researchers and society alike. Particular attention has been put into the recycling of PET, mainly due to its wide spectrum of use and, consequently, to large volumes of related waste. The PET mechanical recycling process requires these waste materials to be shredded into PET flakes. Following such a procedure, these flakes are pelletized to be used again as feedstock. Considering the main stages of the mechanical recycling processes, which include plastic screening, shredding and washing, significant amounts of end waste materials are generated. This end-waste integrates small scale particles that are designated by plastic fines. Concerning the PET recycling process, the PET fines resulting from its mechanical recycling are not currently valued due to several technical issues, such as their high contamination level and the complexity of sorting them from other small-size particles. Current research focuses on the feasibility of incorporating these PET fines into the film/injection extruders, avoiding this way the need for an intermediate pelletization stage. To allow for such direct incorporation of PET fines into recycling processes, different decontamination and sorting solutions were implemented and tested. The current study is based on analyzing the mechanical properties of PET fines, using laboratory tests such as FTIR, DSC, MFI, moisture content, tensile tests and bending tests. Preliminary results allow foreseeing the successful direct incorporation of PET fines into PET recycling.
- Ink Removal on Plastic Films Printed by FlexographyPublication . Bozzola, Fernando; Nascimento, Bruna Guilherme do; Vasco, Joel C.; Silva, Nelson; Lagoa, Fernando; Capela, Carlos; Heleno, Lizete; Gaspar, Marcelo; Oliveira, Nelson S.Plastics are key engineering materials for our society and economy, mainly due to their multifunctionality and ease of processing. Nonetheless, their main drawback is related to the fact that when these cannot be reprocessed, they do generate waste, which leads to several environmental impacts. Therefore, considering plastics’ circularity, minimizing their waste, and the resulting impacts, stresses the need for these to be recyclable. One of the main challenges that concern their recyclability is the deinking of plastic films when printed by flexography. The current technology uses non-bio-based surfactants and non-renewable surfactants, which are harmful to the environment. Therefore, the main objective of current research is to develop an environmentally sustainable process for ink removal on printed post-industrial flexible plastic films using bio-based surfactants. This process focuses on obtaining a deinked plastic that may be reprinted, avoiding this way for inappropriate disposal or reprocessing problems. The value increase of upcycling such post-industrial waste makes it possible to match the quality of the virgin plastic, which is key to carrying out an effective cost analysis of recycled plastic when compared to the new plastic films. Dedicated laboratory deinking procedures were undertaken with transparent polyethylene films printed by flexography with different conditions. Preliminary results show the dedicated experimental ink removal procedure using bio-based surfactants to be effective and environmentally sustainable.
- Energy Efficiency and Sustainability in an Aquaponic Greenhouse Supported by IoTPublication . Galvão, João; Santos, Pedro; Aires, Luis; Ribeiro, Vânia; Neves, FilipeThe increasing demand for agricultural crops and the necessity to reduce environmental impacts from traditional agriculture have led to the emergence of sustainable production systems such as hydroponics and aquaponics. These soil and pesticide-free systems require less water and fertilizers but need electrical energy and controlled greenhouse environmental conditions to be highly productive. This work presents a monitoring and management system for environmental parameters inside an aquaponic greenhouse, that allows the manager to assess in real-time the working status of the aquaponic system, helping in the detection of critical conditions that require a quick decision. This system was developed to measure, through IoT sensors network, the temperature and the relative humidity of the air, the temperature, pH and the electrical conductivity of the water that contains the dissolved nutrients that feed the growth of the plants. It is possible to visualize the measured parameters via the Internet, on a dashboard, in a mobile application and store these variables in a database. To further increase the sustainability of the aquaponic greenhouse, the electricity consumed during its activity will be produced locally by photovoltaic technology. The technologies proposed in this work may promote the emergence of small models of greenhouses, implemented by communities and populations, reducing production energy costs and transportation resources.
