Natural stone has been used worldwide in the construction of archaeological and historical heritage. However, its preservation continues to be threatened by weathering and degradation phenomena. Water is widely recognized as the most threatening external component that contributes to stone deterioration, increasing the need for the development of protective hydrophobic coatings to eliminate water penetration. This study intends to contribute to the better understanding of natural stone treatment strategies to prevent water penetration and subsequent stone alteration by studying the effect of coating and stone substrate temperatures, and the number of coating applications, on the effectiveness, compatibility, and durability of commercial hydrophobic coatings. The results obtained revealed that while more than one application increases coating hydrophobic effectiveness, it frequently leads to changes in the aesthetic appearance of natural stone, including whitening and darkening of the substrate's original hues. Improved hydrophobic effectiveness (maximum gain of ≈ 9%) is also achieved when applying the commercial coatings at 4 °C to natural stone substrates maintained at room temperature, conditions that are feasible to be used in real life. Additionally, the commercial coating composed of silane/siloxane with modified fluorinated additives was found to be the most effective and durable hydrophobic solution. [ABSTRACT FROM AUTHOR]

MURAL art ,MICROSCOPY ,SCANNING electron microscopy ,FOURIER transforms - Abstract
This paper presents the first insight into how Almada Negreiros, a key artist of the first generation of modernism in Portugal, created his mural painting masterpiece in the maritime station of Rocha do Conde de Óbidos in Lisbon. This set of six monumental mural paintings dates from 1946 to 1949 and is considered Almada's artistic epitome. As part of the ALMADA project: Unveiling the mural painting art of Almada Negreiros, the murals are being analyzed from a technical and material perspective to understand his modus operandi and the material used. This is the first study of this nature carried out on site and in the laboratory using standard and more advanced imaging, non-invasive analysis, and microanalysis techniques. This article reports the results obtained with visual examination, technical photography in visible (Vis), visible raking (Vis-Rak), complemented by 2D and 3D optical microscopy (OM), scanning electron microscopy with energy-dispersive spectrometry (SEM-EDS), and Fourier transform infrared micro-spectroscopy (µ-FTIR) of the paint layers. The results show the similarities, differences, and technical difficulties that the painter may have had when working on the first, third, and presumably last mural to be painted. Vis-Rak light images were particularly useful in providing a clear idea of how the work progressed from top to bottom through large sections of plaster made with lime mortars. It also revealed an innovative pounced technique used by Almada Negreiros to transfer the drawings in full scale to the walls. Other technical characteristics highlighted by the analytical setup are the use of textured, opaque, and transparent paint layers. The structure of the paintings does not follow a rigid build-up from light to dark, showing that the artist freely adapted according to the motif represented. As far as the colour palette is concerned, Almada masterfully uses primary and complementary colours made with Fe-based pigments and with synthetic ultramarine blue, cadmium pigments, and emerald green.

NONBINARY people ,FEMINISM ,GENDER-neutral language ,PRONOUNS (Grammar) - Abstract
The rise of feminist and LGBTQIA+ movements paved the way for many equality reforms. These include language reforms, which facilitate inclusion of multiple groups in society. For example, the shift from the generic "he" to "he or she" and "they" allows for the inclusion of women, transgender, and non-binary individuals in many narratives. For this reason, many institutions worldwide encourage neutral language. It remains unclear how individuals interpret neutral language. One case of neutral language is the pronoun "they," which has been assigned multiple definitions from the 1970s to 2022. We examine how the pronoun "they" has been interpreted, used, and accepted over time. We discuss trends in the findings and make suggestions for future research directions, including the need for better methods to investigate pronouns and clarification on what the focus of neutral language should be. This timely commentary has implications for action on equality, diversity, and inclusion. [ABSTRACT FROM AUTHOR]

MICROSCOPY ,PALETTE (Color range) ,MURAL art ,X-ray fluorescence ,PAINTING techniques ,CALCIUM sulfate - Abstract
This study reports the first results of the analysis carried out in 2022 on deteriorated green paint layers from the mural paintings made by Almada Negreiros at the Maritime Station of Alcantara, in Lisbon (Portugal). These murals painted in 1945 are one of the most emblematic painting sets done by the modernist artist and exhibit a bright chromatic palette that displays different states of conservation, with the green paint layers particularly damaged, showing severe flaking and powdering in the lightest shades. To understand the decay phenomenon, in-situ and laboratory analyses were done in an attempt to identify the green chromophores, the painting technique, and the decay agents causing the visible degradation. The analytical setup comprised in-situ technical photography (Vis, Vis-Rak, and UVF), handheld optical microscopy (h-OM), handheld energy dispersive X-ray fluorescence (h-EDXRF), colorimetry, and spectrophotometry in the visible light range. Microsamples of selected paint layers from deteriorated and stable green areas were collected and further analysed in the laboratory by optical microscopy in visible and ultraviolet modes (OM-UV-Vis), variable pressure scanning electron microscopy coupled with energy dispersive spectrometry (VP-SEM-EDS), micro-X-ray diffraction (μ-XRD), micro-Fourier-transform infrared spectroscopy (μ-FT-IR) and micro-Raman spectroscopy. Results show the presence of both natural and industrial synthetic organic pigments, such as green earths and PG8, used alone or in mixtures with other chromophores (e.g., Fe-based yellow and red pigments, bone and carbon black, ultramarine blue, and the synthetic green PG1 and the yellow PY1). Concerning the decay phenomena, the main hypothesis for the powdering and flaking of the green paint layers is the activity of calcium sulphates (e.g., gypsum), which probably originated from both intrinsic and extrinsic sources and whose presence was found to be widespread in all the microsamples analyzed.

- Abstract
Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.

- Abstract
Introdução: A etapa do ciclo de vida das famílias em que os filhos adultos saem de casa, expressa-se por alterações na dinâmica das famílias, implicando reorganização conjugal e redefinição das relações entre pais e filhos. Objetivo: Analisar a perceção de casais sobre a sua conjugalidade em “ninho vazio”; analisar o desenvolvimento de casais e a funcionalidade de famílias em “ninho vazio”; descrever a adaptação dos casais à saída dos filhos adultos de casa; analisar os recursos que facilitaram a adaptação dos casais a esta fase. Métodos: Estudo descritivo exploratório de abordagem qualitativa. Participaram oito casais heterossexuais em “ninho vazio” (N = 16). Amostra recolhida por “bola de neve”. Utilizada entrevista semiestruturada para recolha da informação. Tratamento e análise dos dados realizados através da análise de conteúdo de Bardin, com categorias baseadas no Modelo Dinâmico de Avaliação e Intervenção Familiar. Resultados: Os casais adaptam-se gradualmente às alterações inerentes à saída dos filhos de casa. Mostram-se satisfeitos com a conjugalidade e com a interação mantida com os filhos. As divergências comunicacionais são ultrapassadas, não prejudicando o desenvolvimento conjugal. As estratégias de coping foram eficazes. Nas mulheres, nota-se maior necessidade na dedicação a interesses e atividades lúdicas e de lazer. Conclusão: Os casais estão satisfeitos com a sua conjugalidade, adaptaram-se bem à saída dos filhos e abriram-se à família. O enfermeiro de saúde familiar foi reconhecido como recurso facilitador deste processo de adaptação., Millenium - Journal of Education, Technologies, and Health, Vol. 2 No. 18 (2022): Serie 2, n.º 18

Dissertação de Mestrado em Arte e Património apresentada à Faculdade de Letras Ao bispado de D. Jorge de Almeida (1483-1543) atribuem-se, há muito, investimentos profundamente transformadores da Sé Velha de Coimbra, como a dotação da capela-mor de um monumental retábulo executado por mestres flamengos, o revestimento azulejar do interior da catedral ou a construção dos portais da fachada norte do templo, conhecidos como Porta Especiosa e Porta de Santa Clara. Os dados com que temos lidado para as dinâmicas artísticas da Sé de Coimbra no século XVI devem-se, no entanto, em grande parte, às informações avançadas pelo historiador António de Vasconcelos, na monografia que dedicou à igreja, em 1930-35. Repetidas de forma geralmente acrítica ao longo das décadas, as suas informações carecem de uma imprescindível confirmação e fundamentação científica, tarefa a que se propõe esta dissertação, em aspectos seleccionados. Assim, a partir de um necessário trabalho de pesquisa de fontes documentais, e de um olhar atento à materialidade do edifício, revêem-se, sistematizam-se e problematizam-se, numa primeira parte, as renovações artísticas e as reformas espaciais da iniciativa de D. Jorge de Almeida. A espacialidade interna da Sé é, deste modo, objecto de estudo não só nas modificações introduzidas pelo revestimento azulejar de inícios de Quinhentos, como no que respeita aos seus equipamentos corais. Na segunda parte da dissertação, a partir da reunião e do confronto de diferentes fontes, procura-se apurar a localização aproximada do coro baixo na igreja, bem como as características da sua estrutura ao longo do século. Objecto de um olhar inquiridor é também o claustro quinhentista, em especial no que concerne a Virgem da Anunciação, que há muito se pensa ser proveniente da capela de Santa Maria. No final do século XVI, o bispado de D. Afonso de Castelo Branco (1585-1615) revela-se igualmente interventivo e transformador do fácies da igreja por via de um informado patrocínio artístico. A terceira parte dedica-se, pois, à sua reforma do coro alto, cujas motivações e encomenda se problematizam, e que se procura reconstituir, nas suas sucessivas etapas, bem como na caracterização do seu provável partido estético. The multiple initiatives of Bishop D. Jorge de Almeida (1483-1543) to artistically reform the old cathedral of Coimbra, during the sixty long years he governed the diocese, have long been aknowledged by the artistic historiography. Works that profoundly transformed Sé Velha of Coimbra, such as the monumental altarpiece created by flemish masters Olivier de Gand and Jean d’Ypres, the redecoration of the temple’s interior walls and columns with ceramic tiles or the construction of the north façade portals designated as Porta Especiosa and Porta of Santa Clara, have long been attributed to his commitment in the renewal of the church. However, the information we have concerning this and other bishops’ initiatives are almost all due to the study that historian António de Vasconcelos dedicated to the Sé Velha’s transformations, from its romanic construction until the 20th century restorations, which have been generally, and uncritically, repeated and which lack indispensable confirmation. It is that crucial task of revising and confirming the historical knowledge of selected aspects of the artistic dynamics the old cathedral underwent, in the 16th century, that we undertake in this dissertation. Based on the research of historical sources and on the careful observation of the building’s characteristics, the artistic and spatial renovations ordered by D. Jorge de Almeida are therefore sistematized and problematized in the first part of our dissertation. The spatial changes the cathedral underwent in the 16th century are also considered, in particular on what pertains to the two choirs of the church. The second part of the present dissertation is thus concerned with trying to approximately locate, inside the church, the first choir, as well as defining its structure. The 16th century cloister, and specially the sculpture of the Virgin of the Annunciation, which is now thought to proceed from the Santa Maria chapel, in the cloister, are also briefly discussed. In the final years of the 16th century, Bishop D. Afonso de Castelo Branco (1585-1615) displayed an equally transformative and informed attitute regarding the interior ecclesial space. For that reason, in the final part of our dissertation we attempt to retrace the spatial and artistic renovation of the upper choir, which the bishop claimed as his enterprise, as well as to understand the reasons behind this operation, its commission and probable aesthetic features.

Purpose: The aim of this study was to characterize and compare the behavior of human osteoblasts and human gingival fibroblasts in contact with polyetheretherketone (PEEK), zirconia, and titanium implant surface materials. Materials and Methods: PEEK, yttria-stabilized zirconia (YTZP), and titanium disks were produced under appropriate and similar conditions to achieve controlled surface features. Human osteoblasts and human gingival fibroblasts were cultured on disks for 14 days. Cell viability and proliferation were evaluated using a resazurin-based method. Morphology and cellular adhesion were observed using field emission gun-scanning electron microscopy (FEG-SEM). Alkaline phosphatase (ALP) activity and bone cell mineralization was evaluated on osteoblasts. Confocal laser scanning microscopy (CLSM) images of fluorescent-stained fibroblasts were obtained at 7 and 14 days of the culture. Results were presented as mean and standard deviation (SD). Group comparisons were tested using analysis of variance (ANOVA) (Tukey's post hoc) with appropriate statistical software, and significance was set at P < .05. Results: Cell viability and proliferation were higher in PEEK and YTZP groups compared with titanium on osteoblast cells (P < .05, all time points) and on fibroblasts (P < .05, 7 and 14 days). All groups showed an increase in ALP activity over time, which was not significant. Mineralization patterns demonstrated an increase in mineral content over time, which was more apparent in the YTZP group. Cell spreading was more evident on PEEK and YTZP specimens. Conclusion: The results suggest increased adhesion, viability, and proliferation of osteoblasts and gingival fibroblasts on zirconia and PEEK surfaces compared with titanium. These results are correlated with the increased wettability of these materials. [ABSTRACT FROM AUTHOR]

A “Maria Terra” surgiu de necessidades identificadas nas pessoas que nos rodeiam. A crescente procura por atividades de bem-estar, o desagrado pela experiência de compras nas lojas de roupas e a falta de oferta de espaços atrativos e com opções saudáveis de alimentação em Cascais levou à idealização deste projeto. A ideia será proporcionar experiências agradáveis aos clientes que frequentem o espaço, onde serão influenciados por diversos fatores, nomeadamente o aroma, o som, as texturas e um atendimento personalizado e cuidado. Terão ao seu dispor a oferta de vários produtos e serviços. Realizámos um estudo de mercado sobre o negócio de forma a verificarmos a sua aceitação e viabilidade. Os resultados foram positivos, verificámos o agrado dos potenciais clientes e os vários pontos fortes do negócio que deverão ser otimizados. Acreditamos que, apesar de vivermos um momento de incerteza, cada vez mais as pessoas procuram soluções para se sentirem bem. É precisamente neste mercado que pretendemos operar e proporcionar experiências agradáveis aos nossos clientes. O projeto tem ainda espaço para se adaptar às necessidades e gostos do cliente, o que será um ponto positivo para o fazer sentir envolvido com a marca. A personalização que teremos também será relevante para agradar o target da “Maria Terra”. Este conceito inovador terá preocupações com a sustentabilidade, confeção nacional, bem-estar dos trabalhadores, qualidade oferecida e alguma exclusividade, o que consideramos serem fatores que revelam a essência da marca. “Maria Terra” arose from the needs identified in people around us. The growing demand for wellness activities, the dissatisfaction with the shopping experience at clothing stores and the lack of attractive spaces and healthy eating options in Cascais led to the idealization of this project. The idea consists in providing pleasant experiences to customers, who frequent a space where they will be influenced by several factors, namely the aroma, sound, textures and a personalized and careful service. They will have various products and services at their disposal. We conducted a study on the market and business in order to verify its acceptance and viability and the results were positive. We verified the market acceptance and the various strengths of the business that should be optimized. We believe that despite experiencing a moment of uncertainty, more and more people are looking for solutions to feel good. It is precisely in this market that we intend to operate and provide pleasant experiences to our customers. The project also has space to adapt to the needs and tastes of the customer, which will help them feel involved with the brand. The customization that we’ll have is also going to be relevant to please the brand target. This innovative concept will be concerned with sustainability, local Portuguese production, workers' well-being, the quality offered and with some exclusivity, which we consider to be factors that reveal the essence of the brand.

The Segura mining field, the easternmost segment of the Góis–Panasqueira–Segura tin–tungsten metallogenic belt (north–central Portugal), includes Sn-W quartz veins and Li-Sn aplite-pegmatites, which are believed to be genetically related to Variscan Granites. Sediment geochemistry indicates granite-related Ti-enrichments, locally disturbed by mineralization, suggesting magmatic and metamorphic/metasomatic titaniferous phases. Therefore, Segura alluvial samples and the geochemistry of their TiO
2 polymorphs (rutile, anatase, and brookite) were investigated, and their potential as exploration tools for Sn and W deposits was evaluated. The heavy-mineral assemblages proved to be good proxies for bedrock geology, and TiO2 polymorph abundances were found to be suitable indicators of magmatic and/or metasomatic hydrothermal processes. The trace element geochemistry of Segura's alluvial rutile, anatase, and brookite is highly variable, implying multiple sources and a diversity of mineral-forming processes. The main compositional differences between TiO2 polymorphs are related to intrinsic (structural) factors, and to the P-T-X extrinsic parameters of their forming environments. Anomalous enrichments, up to 9% Nb, 6% Sn and W, 3% Fe, 2% Ta, and 1% V in rutile, and up to 1.8% Fe, 1.7% Ta, 1.2% Nb, 1.1% W 0.5% Sn and V in anatase, were registered. Brookite usually has low trace element content (<0.5%), except for Fe (~1%). HFSE-rich and granitophile-rich rutile is most likely magmatic, forming in extremely differentiated melts, with Sn and W contents enabling the discrimination between Sn-dominant and W-dominant systems. Trace element geochemical distribution maps show pronounced negative Sn (rutile+anatase) and W (rutile) anomalies linked to hydrothermal cassiterite precipitation, as opposed to their hydrothermal alteration halos and to W-dominant cassiterite-free mineralized areas, where primary hydrothermal rutile shows enrichments similar to magmatic rutile. This contribution recognizes that trace element geochemistry of alluvial TiO2 polymorphs can be a robust, cost- and time-effective, exploration tool for Sn(W) and W(Sn) ore deposit systems.

Plano de Projeto submetido como requisito obtenção do grau de Mestre em Segurança e Higiene no Trabalho O progressivo envelhecimento demográfico consequente de uma longevidade crescente traduz uma conquista importante da humanidade uma vez que este fator está associado à existência de condições de vida favoráveis ao aumento da esperança média de vida. Como consequência do envelhecimento e, considerando que a população dum modo geral tem de continuar a trabalhar até mais tarde, as famílias não podem dedicar-se a cuidar dos familiares mais idosos recorrendo muitas vezes às intuições de apoio social, nomeadamente os lares de idosos. Na ausência da família ou de alguém próximo que cuide dos idosos são as atividades de apoio social com alojamento que prestam apoio aos idosos da comunidade, os chamados lares ou residências de idosos. Este apoio traduz-se na promoção da saúde física e mental dos utentes a par da existência de uma rede de afetos e ligações emocionais indispensável ao bem-estar dos Idosos bem como atividades físicas. Desta forma, surgem as instituições de apoio social e nelas encontram-se indivíduos, intitulados como trabalhadores que assim como noutros locais trabalho se encontram sujeitos a perigos e riscos que devem ser monitorizados, eliminados ou minimizados. O objetivo principal deste trabalho é otimizar os escassos procedimentos de segurança já estabelecidos num lar de idosos de forma a promover a higiene, saúde e segurança no local de trabalho, assegurando a integridade física e psíquica dos/as trabalhadores /as, assim como a prevenção de riscos profissionais, de forma a prevenir e diminuir acidentes de trabalho e doenças profissionais. Foi analisada a situação atual do lar em termos de Saúde e Segurança no Trabalho e foram propostas melhorias que passaram pela elaboração de uma nova matriz de avaliação de riscos, pela avaliação da perceção de riscos por parte dos trabalhadores através de um inquérito e foi elaborado um manual de boas práticas ajustado às suas necessidades e com as diretrizes necessárias para a existência de conhecimentos acerca da matéria e para a sensibilização dos trabalhadores a essas práticas. The progressive demographic aging resulting from an increasing longevity translates an important achievement of humanity since this factor is associated to the existence of living conditions favorable to the increase in average life expectancy. As a consequence of ageing and, considering that the population in general has to continue to work until later, families cannot devote themselves to caring for older family members, often resorting to social support intuitions, such as the nursing homes. In the absence of the family or someone close to care for the elderly, the social support activities like nursery homes provide support to the elderly in the community. This support consists in the promotion of the physical and mental health of users along with the existence of emotional connections indispensable to the well-being of the elderly such as physical activities. In this way, the support institutions arise and there are individuals, entitled as workers who, as well as in other workplaces, are subject to hazards and risks that must be monitored, eliminated or minimized. The main objective of this work was to optimize the safety procedures already established in a nursing home in order to promote hygiene, health and safety in the workplace, ensuring the physical and mental integrity of workers, as well as the prevention of occupational risks, and in order to prevent and reduce work accidents and occupational diseases. The current situation of the nursery home associated to the Health and Safety at Work was analyzed and there were proposed improvements that went through the elaboration of a new risk assessment, the analysis of the workers risks’ perception and through the elaboration of Good Practice’s Manual adjusted to the workers needs.
