A antiga indústria têxtil algodoeira portuense. O resgate da memória de um património industrial desaparecido
No full textO Património Industrial é hoje uma categoria patrimonial valorizada em muitos âmbitos,
desde o museológico ao turístico, sendo o reuso adaptativo a prática mais recomendada
para a sua salvaguarda, no caso de edifícios fabris desativados. Mas, quando o edifício
produtivo já despareceu, tem sentido resgatar a sua memória? E como fazê-lo para além do
âmbito museológico? Esta tese tem como objeto de estudo a antiga indústria têxtil
algodoeira portuense, representada neste trabalho por sete conjuntos fabris instalados no
Porto entre 1850 e 1907. Esta indústria, pioneira, desenvolveu um papel fundamental no
processo de industrialização da cidade e da região Noroeste do país. Foi nesta região que,
ao longo do século XX, a indústria têxtil urbana se deslocalizou, consolidando o núcleo
preexistente, que evoluiu num importante polo têxtil. Os antigos estabelecimentos fabris
algodoeiros portuenses continuaram em função, empregando milhares de operários; a sua
presença, ao longo de aproximadamente 150 anos, influenciou o crescimento urbano,
configurando uma paisagem industrial que já em 1866 tinha proporcionado ao Porto o
apelativo de “Manchester portuguesa”. Hoje, não há mais vestígios destas fábricas, à
exceção de um conjunto que, reconvertido num centro empresarial, manteve quase
inalteradas as características do antigo estabelecimento fabril. Desativadas a partir da
década de 1950, e sucessivamente demolidas, deixaram espaço para novas urbanizações,
algumas das quais tornaram-se ícones da paisagem do Porto contemporâneo. Canceladas
do espaço da cidade, caíram no esquecimento, vivendo apenas na memória de quem as
vivenciou diretamente ou indiretamente. O objetivo desta tese é reconstruir as suas
histórias, fundamentando-as cientificamente para o seu reconhecimento enquanto
património industrial da cidade, construindo uma entre as tantas narrativas possíveis. Esta e
outras narrativas, que se espera possam surgir em futuro, permitirão divulgar o
conhecimento deste património, até hoje invisível, abrindo uma reflexão sobre possíveis
caminhos para o resgate da sua memória; - The former Porto’s cotton textile industry. Rescuing the memory of a lost industrial
heritage
ABSTRACT:
Industrial heritage is today a valued heritage category in many areas, from museums to
tourism, and adaptive reuse is the recommended practice for its safeguarding, for
deactivated plants. But when the production building have already disappeared, does it
make sense to rescue its memory? And how to do it beyond the museum context? This
thesis has as its object of study the old cotton textile industry in Porto, represented by
seven factory complexes installed between 1850 e 1907. This pioneer industry played a
fundamental role in the industrialization process of the city and of the Northwest
Portuguese region. It was here that, throughout the 20th century, the urban textile industry
relocated, consolidating the pre-existing nucleus that evolved into an important textile hub.
The large cotton manufacturing establishments in Porto continued to evolve, employing
thousands of workers; its presence, over 150 years, influenced urban growth, creating an
industrial landscape that, in 1866, had given Porto the title of “Portuguese Manchester”.
Today, there are no traces of these factories, with the exception of a complex that,
converted into a business centre, has maintained the characteristics of the old factory
complex almost unchanged. Deactivated from the 1950s onwards, and successively
demolished, they left space for new urbanizations, some of which have become icons of
the landscape of contemporary Porto. Cancelled from the city space, they fell into oblivion,
living only in the memory of those who experienced them directly or indirectly. The
objective of this thesis is to reconstruct their stories, scientifically, for their recognition as a
city's industrial heritage, constructing one of the many possible narratives. This and other
narratives, which we hope may emerge in the future, will make possible to disseminate
knowledge of this heritage that, nowadays invisible, opening up a reflection on possible
ways to rescue its memory
Advanced Geophysical Processing of Ground-Penetrating Radar and Magnetic Datasets
No full textDue to the presence of an excessive amount of noise in the data, archeological geophysics frequently produces results that cannot be used to evaluate the content that may exist in the subsurface. If it is impossible to differentiate between signal and noise, excessive noise will result. Its genesis, when it is attributable to heterogeneities in the ground (overthrows, corners) that produce as many reflections as structures that may exist, prevents a fair assessment of the subsoil composition. Low perceptibility circumstances happen when there is no contrast between buried structures and the surrounding environment. It could be due to elements that are harmful to the method (metals and ceramics in the magnetic method; clay and water in the electromagnetic method) or when the buried objects are formed of the same material as the surrounding medium. The problem of the identification and selection of useful signals in geophysical data is one of the research topics of effective methodologies of archeological geophysics, with the aim of producing more accurate models that allow a more precise interpretation of structures buried beneath the earth. In this paper, three approaches conceived by the team are described, which allow: to increase the sharpness of the GPR models by reducing the background noise through factoring techniques applied in the 2-D spectral domain; to increase the resolution of the models by increasing the density of the profiles with Fourier interpolation; and to increase model information by combining maps from the two geophysical methods, using data fusion techniques that combine mathematical transformations and statistical analysis
Jorge Malheiros
No full textNascido em 1966, Jorge Malheiros passou a sua infância num ambiente muito politizado, em que a contestação à ditadura e o combate ao fascismo faziam parte do quotidiano. Activista nas lutas estudantis dos anos 60, o seu pai – Manuel Macaísta Malheiros – acabaria por ser defensor dos presos políticos no Tribunal Plenário, tendo
sido o advogado de defesa do processo do assalto ao Quartel de Beja e, depois do 25
de abril, integraria, como ministro do Comércio Interno, o quinto Governo Provisó-
rio. Dificilmente o jovem Malheiros poderia ter permanecido indiferente às suas pró-
prias circunstâncias
Developing Critical Thinking in Higher Education: Is There a Reason to Change?
No full textCompetency-based veterinary education has been proposed for long, but its implementation accelerated in recent years. It endorses the development of specific abilities, that are identified, and needed for a wide range of professional tasks. Nevertheless, the University's adaptation to the proposed competency-based framework is not always easy. It often depends on economic and administrative constraints and requests some time until the completion of the reforms. This time-lapse foster the skills mismatch existing between Academia and the labor market. Think4Jobs project organized focus groups interviews with Veterinarians with experience across many professional areas (e.g., clinical, food production and food safety, research), pre-graduate students and teachers, to identify core critical thinking-related competencies deemed crucial by the labor market. Triangulating the beliefs of Stakeholders and University detected some differences in the importance of competency domains, sustaining the need to change the pedagogical approach during learning and during the traineeships to enhance autonomy, self-regulation, and self-confidence in students’ clinical reasoning and decision-making skills. Based on the identified differences, the framework presented herein was proposed to strengthen the acquisition of those competencies across existing curricula
Dinosaur tracksites from Portugal, focused on the carbonated platform of north and central Lusitanian Basin
No full textThe fossil record of Portuguese dinosaur tracks is exceptionally diverse, with
more than 110 tracksites, spanning from the Carnian to Cenomanian. From those, two
thirds are from the Upper Jurassic of Lusitanian Basin. This study synthesizes existing
knowledge while introducing new findings from eight underexplored tracksites in the
Upper Jurassic of the Lusitanian Basin: Praia do Pedrógão, Praia do Salgado, Vale de
Ventos, Pedreira/Amoreira, Serra de Mangues, Salir, Serra do Bouro and Consolação.
These sites collectively contribute with 100+ trackways and 400+ tracks, representing
theropods, sauropods, ornithopods, thyreophorans, and undetermined taxa, accounting
for approximately 7% of all Portuguese tracks and tracksites. The ichnotaxonomy
identifies 10 ichnotaxa, with notable new records for Portugal, including Kayentapus
minor. Preservation insights include elongated tracks in soft mud (e.g., Praia do Salgado)
and unique swimming tracks at Salir, interpreted as reflecting shallow-water
environments with directional currents. Dominance of theropod tracks contrasts with their
skeletal fossil record, emphasizing the utility of ichnological data in understanding
dinosaur ecology and behavior. The findings have significant paleobiogeographic
implications. Dinosaur tracks on tidal-flat platforms highlight nearshore environments,
refining paleogeographic reconstructions of the region. Rare ankylosaur tracks in the
Kimmeridgian suggest an earlier dispersal of Dracopelta-like lineages before the
Kimmeridgian. This work underscores the importance of Portugal's ichnological record
in global dinosaur studies as well as its importance as a touristic asset. - Jazidas de pegadas de dinossauros de Portugal, com foco na
plataforma carbonatada do norte e centro da Bacia Lusitânica - RESUMO: O registo fóssil de pegadas de dinossauros em Portugal é excecionalmente
diverso, com mais de 110 jazidas, do Carniano ao Cenomaniano. Destes, dois terços
estão no Jurássico Superior da Bacia Lusitânica. Este estudo sintetiza o conhecimento
existente e apresenta novos dados de oito jazidas de pegadas pouco conhecidas do
Jurássico Superior da Bacia Lusitânica: Praia do Pedrógão, Praia do Salgado, Vale de
Ventos, Pedreira/Amoreira, Serra de Mangues, Salir, Serra do Bouro e Consolação.
Estes locais contribuem, no total, com mais de 100 trilhos e mais de 400 pegadas,
representando terópodes, saurópodes, ornitópodes, tireóforos e táxones
indeterminados, o que equivale a cerca de 7% do total de pegadas e jazidas conhecidas
em Portugal. A icnotaxonomia identifica 10 icnotáxones, com registos inéditos para
Portugal, incluindo Kayentapus minor. As particularidades de preservação incluem
pegadas alongadas em sedimentos moles (e.g., Praia do Salgado) e pegadas únicas de
natação em Salir, interpretadas como resultado de ambientes de águas rasas com
correntes direcionais. A predominância de pegadas de terópodes contrasta com o
registo fóssil esquelético destes dinossauros, realçando a utilidade dos dados
icnológicos para compreender a ecologia e o comportamento dos dinossauros. Os
resultados apresentam importantes implicações paleobiogeográficas. As pegadas de
dinossauros em plataformas intertidais carbonatadas destacam ambientes costeiros,
refinando as reconstruções paleogeográficas da região. Pegadas raras de
anquilossauros no Kimmeridgiano sugerem uma dispersão mais precoce de linhagens
semelhantes a Dracopelta antes do Kimmeridgiano. Este trabalho sublinha a
importância do registo icnológico português nos estudos globais de dinossauros, bem
como o seu potencial enquanto recurso turístico
Analysis of residues remains on experimental stone tools use and raw material variability
No full textDespite the abundance of experiments on stone tool residues, experimentation to test whether residue
deposition and preservation are significantly varied on flakes knapped from different raw materials remains
unstudied. Consequently, an experiment was designed to systematically assess whether there are significant
variations in the deposition and preservation of use-related residues on the surface of flaked stone tools
manufactured from different rocks. Flaked stone tools obtained from dacite, quartzite, flint, and obsidian
were utilized for cutting fresh bone for depositing residues, followed by burial for a period of two months.
In comparing residue deposition and preservation on experimental flaked stone tools used for processing
bone, the surface areas of the flakes covered by residue were measured. The results revealed that fresh
residues on flakes knapped from porous and rough raw materials (rocks), such as dacite and quartzite,
exhibited significantly greater areal coverage (i.e., higher residue deposition) on the tool surfaces
compared to less porous and smoother materials such as flint and obsidian. However, this variation was
not apparent in terms of preservation during the experimental time after burial; in fact, the degree of
reduction in residue area coverage showed similarity between the lithologies; - RESUMO:
Analysis of Residues Remains on Experimental Stone Tools Use and Raw Material Variability
Apesar dos vários trabalhos existentes sobre os resíduos em ferramentas de pedra lascada, a
experimentação, com o intuito de testar se a deposição e preservação de resíduos varia
significativamente com diferentes matérias-primas permanece por estudar. Neste sentido, foi
desenhado um trabalho de arqueologia experimental para avaliar se existem variações
significativas na deposição e preservação de resíduos relacionáveis com diferentes rochas.
Ferramentas de pedra lascada, obtidas a partir de dacito, quartzito, chert e obsidiana, foram
utilizadas para cortar osso fresco tendo posteriormente sido enterradas por um período de dois
meses. As áreas de deposição e preservação cobertas por resíduos foram medidas, tendo sido
comparadas. Os resultados revelaram que resíduos frescos em lascas cortadas de matériasprimas
porosas e rugosas, como o dacito e o quartzito, exibiram uma área coberta
significativamente maior (ou seja, maior deposição de resíduos) comparativamente a materiais
menos porosos e mais lisos, como o chert e obsidiana. No entanto, esta diferença, não se verificou,
no período experimental, em termos de preservação após enterramento; a redução média na área
coberta por resíduos foi similar para as várias litologias
Land-use evolution in an island urban setting: A three-decade analysis of Machico, Madeira (1990–2018)
No full textThe sustainable development of Madeira Island necessitates the implementation of
more precise and targeted planning strategies to address its regional challenges. Given the
urgency of this issue within the context of sustainability, planning approaches must be
grounded in and reinforced by a comprehensive array of thematic studies to fully grasp the
complexities involved. This research leverages Geographic Information Systems (GIS) to
analyze land use and occupancy patterns and their evolution within the municipality of
Machico on Madeira Island. The study provides a nuanced perspective on the urban
structure’s stagnation in the region, while concurrently highlighting the dynamic shifts in
agricultural practices. Furthermore, it elucidates the transformation of predominant native
vegetation within the municipality from 1990 to 2018. Notably, the research underscores the
alarming decline in native vegetation due to anthropogenic activities, emphasizing the need
for more rigorous monitoring by regional authorities to safeguard and preserve these valuable
landscapes, habitats, and ecosystems
The Recent Spatiotemporal Dynamics of Grasslands in Slovenia: Contribution to Their Preservation and Management
No full textSeminatural European grasslands and pastures have a high conservation value because they provide different goods and services (meat, wool, carbon sequestration, etc.) and harbor diverse communities of plants and animals. These land use systems were created by low- and moderate-intensity use and, nowadays, face threats from both abandonment and overuse. Although less productive or less accessible areas are abandoned, triggering afforestation processes, others are subject to intensive agricultural practices with the addition of production factors and modern management schemes. Neither is comparable with the traditional uses that first formed and maintained these systems for generations, and therefore, it is fundamental to design effective policies to ensure a sustainable territorial coexistence of modern agriculture and traditional pastures and grasslands. In this work, we assessed the recent dynamics of pastures and grasslands in Slovenia. The results show distinct local changes and a nationwide general dynamic of area reduction and loss of patches. After elaborating on how such changes affect the landscape and some species according to their traits, we provide practical recommendations for policy design to contribute to protecting and promoting this land use system. We argue that the two major priorities should be to preserve the most relevant patches and to try to convert other land uses into grasslands, preferably attempting to merge separated patches and thus increasing the mean patch size of grasslands. Overall, by identifying trends, locating the different spatial changes, and complementing with a connectivity analysis, this approach can be valuable in identifying effective measures to protect and improve grasslands. Besides the concrete results obtained from the Slovenian case study, the underlying rationale and workflow can be applied elsewhere to produce similar outputs that help identify land transformation patterns and interpret specific land use category dynamics

Nature and one health - based solutions to help ecological restoration: designing pilot strategies for Quinta Ecológica da Moita, Portugal
No full textFaced with the current biodiversity crisis, the climate change and the global ecosystem
degradation, ecological restoration shows itself like the most important tactic to reverse the
current situation. However, nowadays ecosystem restoration strategies cannot be seen just as an
ecological intervention. It’s necessary to engage different types of knowledge, stakeholders and
policies, just like populations values and culture, to decide the best strategies to apply at the
restoration sites, ensuring that all parties see their objectives achieved and find success. Naturebased Solutions supports this integrative perspective. According to the characteristics of Quinta
Ecológica da Moita, place for which the present pilot strategies are designed, a One Health
approach will also be taken into consideration.
The main goals of this dissertation were to design strategies based on nature and One
Health approach, to make the QEM’s ecological restoration action as current, efficient and
inclusive as possible, for a sustainable, healthy future; - Soluções Baseadas na Natureza e em Uma Saúde para Apoiar o
Restauro Ecológico: Desenvolvimento de Estratégias Piloto para a
Quinta Ecológica da Moita, Portugal -
Resumo:
Face à atual crise de biodiversidade, às mudanças climáticas e à degradação dos
ecossistemas, o restauro ecológico revela-se como o método mais importante para inverter a
situação atual. No entanto, as estratégias para restauro de ecossistemas não podem ser vistas
apenas como uma intervenção ecológica. É necessário envolver diferentes tipos de
conhecimento, partes interessadas, políticas, e os valores e cultura das populações, de forma a
conceber as melhores estratégias, garantindo que todas as partes alcançam os seus objetivos e
encontram sucesso. As Soluções Baseadas na Natureza apoiam esta perspetiva integradora. De
acordo com as características da Quinta Ecológica da Moita, local para o qual foram desenhadas
as presentes estratégias-piloto, será tida também em consideração uma abordagem Uma Saúde.
Os principais objetivos desta dissertação foram desenhar estratégias baseadas na
natureza e numa abordagem Uma Saúde, para tornar a ação de restauro da QEM o mais atual,
eficiente, inclusiva e sustentável possível
