Esta pesquisa objetivou realizar interpretações paleoambientais do estuário do rio Real durante o Holoceno Tardio, com base em foraminíferos bentônicos e bivalves. Foram utilizados, além dos organismos, dados granulométricos de dois testemunhos rasos de sondagens. A granulometria, predominantemente arenosa, evidenciou um ambiente de elevada energia hidrodinâmica, respaldado pelo registro de organismos autóctones (bivalves). Em 12 amostras do testemunho T01, foram encontrados 606 foraminíferos de 20 espécies, no testemunho T02, 119 espécimes de três espécies foram registrados em quatro amostras. A presença do gênero Trochammina no T01, especialmente na fácies-G1 (base a 105 cm), indica um ambiente de estuário médio com influência fluvial. As fácies-G1 e G3 (70 a 50 cm) apresentam um pacote sedimentar areno-lodoso, característico de um ambiente fluvial. Os registros de bivalves na fácies-G4 (50 a 15 cm) indicam uma Zona de Estuário Baixo com influência marinha. As fácies-G2 (105 a 70 cm) e G4 mostram espécies de bivalves eurihalinos, sugerindo um depósito transgressivo de transição offshore. A fácie-G5 (15 cm ao topo) apresenta foraminíferos e bivalves de ambientes salobros a marinhos rasos, classificando-o como o estuário com depósitos transgressivos. No T02, as fácies-Z1 (base a 205 cm) e Z3 (175 a 15 cm) são ambientes estéreis em foraminíferos e bivalves, característicos de um ambiente de água doce com provável progradação de sedimentos continentais. A fácie-Z2 (205 a 175 cm) registrou apenas o bivalve marinho Diplodonta cf. notata, associado à granulometria arenosa, sugerindo um ambiente marinho raso. A fácie-Z4 (15 cm ao topo) representa o estuário atual, com predominância de espécies de foraminíferos calcário-hialinos, corroborando um domínio marinho em relação ao fluvial. Nesse sentido, as interpretações das correlações entre os dados abióticos e bióticos obtidos dos perfis T01 e T02 ao longo do Holoceno Tardio revelaram variações significativas nas condições paleoambientais durante o período de mar baixo, que descrevem as mudanças ocorridas nesse ecossistema ao longo do tempo e enriquecem nossa compreensão dos padrões de resposta das comunidades bióticas às oscilações ambientais durante o Holoceno Tardio.

Published: December 2024

Albian carbonate reservoirs of the Quissamã Formation have been an important target for oil exploration and production in the Campos Basin for several decades. The variety of depositional facies and the influence of diagenesis in reducing porosity and permeability create great challenges for the exploration and production of these reservoirs. The objective of this study is to identify the main depositional and diagenetic factors that control the porosity and permeability of Albian carbonates in 3-OGX-61-RJS well located in the Tubarão Azul area, southern Campos Basin, through a faciological, petrology and petrophysical integrated analysis. Observed lithofacies include oolitic, oncolitic and peloidal calcarenites, oncolitic and peloidal calcirudites, and hybrid arenites, deposited in a shallow carbonate ramp. The depositional facies were grouped into two facies associations: a high-energy proximal carbonate ramp composed of hybrid sandstones, oncolitic and oolitic calcarenites, and oncolitic calcirudites, and a moderate-energy intermediate carbonate ramp composed of peloidal and oncolitic calcarenites with peloids. The depositional facies were grouped into two facies associations: a high-energy proximal carbonate ramp composed of hybrid arenites, oncolitic and oolitic calcarenites and oncolitic calcirudites, and a moderate-energy intermediate carbonate ramp composed of peloidal and oncolitic calcarenites with peloids. Nine reservoir petrofacies were defined based on the main primary and diagenetic aspects of impact on porosity and permeability. The main observed diagenetic processes were cementation by calcite, replacement by blocky dolomite and pyrite, kaolinite precipitation, mechanical and chemical compaction, including stylolitization, and eodiagenetic and mesodiagenetic dissolution. Early partial cementation by calcite rims and syntaxial growths helped preserve the primary porosity of oolitic and oncolitic calcarenites from the effects of compaction. Interparticle porosity was completely obliterated where eodiagenetic cementation was very intense. Hybrid arenites with little or no early cementation show porosity and permeability extremely reduced by the effects of compaction. These fundamental processes acted directly to control the porosity and permeability of the studied rocks.
Analysis of coherence areas between conjugate stations affected by the South Atlantic Magnetic Anomaly

Published: December 2024

The South Atlantic Magnetic Anomaly (SAMA) is a region in the South Atlantic Ocean where the Earth's magnetic field is significantly weaker than in other parts of the world. This anomaly has been of interest to scientists and researchers studying the Earth's magnetic field. The SAMA can affect navigation systems and satellite operations, and it is an important area of study for understanding the dynamics of the Earth's magnetic field. This paper investigates the signal characteristics of conjugate stations influenced by the SAMA in a moderate geomagnetic storm through record analysis of geomagnetically conjugate stations interlinking both hemispheres. This study uses the horizontal magnetic components measured in the same time interval in two typical longitudes: the America-SAMA region and the Asia-Pacific one. This procedure allows us to do a comparative analysis between regions. Our procedure uses the data recorded simultaneously in four conjugate-station pairs to characterize the magnetic variability coherence domain surrounding conjugate stations. Here, we present and discuss the first maps of the SAMA region, which corresponds to the coherence area at low latitudes. Indeed, this coherence area concept refers to the edges (close-to-the-ground geometric area) around the conjugate point, where geophysical phenomena generally exhibit similar fluctuating behavior. The correlation coefficients technique was used to calculate those areas, using the H component of the geomagnetic field. Our main results indicate that the areas in the Asia-Pacific region are similar in size and shape, which characterize typical patterns. In the America-SAMA region, the coherence areas for the conjugate stations are not similar in shape and size. These differences between coherence areas could be due to the region's unique characteristics, i.e. it presents an enhanced ionospheric conductivity. Additionally, geomagnetic stations inside a large area of South America, involving the Santa Maria region, will present, in principle, magnetic fluctuations with similarity in the records.
"CRISTIANISMO DESCOLADO"
Authors: Rocha Cristina
Published: December 2024

Neste artigo, analiso como a moda, as megaigrejas e a cultura jovem e de celebridade se unem no século XXI, dando origem ao fenômeno do “cristianismo descolado”. Afirmo que esse cristianismo voltado para os jovens de classe média não é criado apenas pelas megaigrejas em uma tentativa de atrair as novas gerações, como geralmente se argumenta. Ele também é produzido por celebridades, pelo setor da moda e por jovens empreendedores cristãos. Argumento que esse conjunto de diferentes elementos gera um “complexo industrial de moda, celebridade e megaigrejas” que torna o cristianismo atraente para os jovens de classe média, pois eles não encontram pertencimento em igrejas mais conservadoras. Uso o conceito de “formação estética” de Meyer (2009) para demonstrar como esse complexo industrial une os jovens especialmente em sua transição para a vida adulta. Tambémdemonstro que, pelo fato de o cristianismo descolado ser um estilo estético relativamente novo, ele se torna altamente visível e precisa ser negociado com estilos mais antigos. Este artigo se baseia em seis anos de trabalho de campo multi-situado presencial (na megaigreja australiana Hillsong na Austrália e no Brasil) e online (monitorando e analisando seus cultos online e presença nas mídias sociais e como os fiéis interagem com elas, bem como reportagens da mídia sobre a igreja).

Published: December 2024

Realizamos un diagnóstico de las disciplinas de Prácticas Corporales de Aventura (PCA) en los grados en Educación Física de las universidades públicas españolas. Recopilamos datos consultando sitios web de las universidades y encontramos 53 asignaturas en 29 instituciones. Sometemos los documentos recopilados a un análisis de contenido. Un grupo de disciplinas se centra de forma genérica/conceptual en las PCA mientras que otro se ocupa de prácticas específicas, como el surf o el esquí. Las genéricas están en los primeros cursos y casi todos son obligatorios; las específicas están en los últimos años y en su mayoría son opcionales. No existe una distinción conceptual explícita entre actividad y deporte, ni entre medio natural, naturaleza y medio ambiente, pero, en general, se refieren a espacios no regulados. Las universidades de Huelva y el INEFC-Pirineus ofrecen grados con profundización en PCA, con seis y ocho asignaturas respectivamente, destacando entre otras instituciones.
Pedagogia da Rua ainda existe?
Authors: Fischer Thomas , Orenga Sandoval Gabriel , Nogueira Silva Luis Felipe , Scaglia Alcides José
Published: December 2024

No Brasil, a Pedagogia da Rua marcou a infância de muitos jogadores de futebol, caracterizando um processo de aprendizagem da modalidade com base nos jogos/brincadeiras em ambientes informais. Porém, o jogar/brincar na sociedade contemporânea tem sofrido ressignificações, impactando a cultura lúdica de crianças e jovens e suas relações com o esporte e outras práticas corporais. Sendo assim, a partir de uma abordagem qualitativa e entrevistas semi-estruturadas, este estudo teve por objetivo comparar a cultura lúdica de jogadores(as) profissionais de futebol da atual geração com a cultura lúdica de ex-jogadores, de modo a identificar possíveis similaridades e singularidades no processo de aprendizagem do futebol. Os resultados encontrados sugerem que a Pedagogia da Rua permanece viva na cultura lúdica dos(as) atuais jogadores(as) de futebol. Pois, ainda que o local majoritário de prática, aparentemente, tenha se alterado (deixando de ser a rua propriamente dita, e passando a espaços como quadras poliesportivas), o ambiente informal de aprendizagem colaborativa, que caracteriza a Pedagogia da Rua, segue presente nos relatos da atual geração.

Ribociclib-induced phototoxicity - the era of new drugs and new toxicities
Authors: Bobic Simonida , Poparic-Bandjur Bojana , Matovic Milana , Pavlovic Lidija , Milovic-Kovacevic Marijana
Published: December 2024

Introduction. Ribociclib belongs to the family of cyclin-dependent kinases 4/6 inhibitors and it has been approved in 2017 for the treatment of patients with hormone receptor-positive (ER+) and human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. As a drug that has been used for treatment of breast cancer for only few years its rare side effects are described through different case reports. Skin photosensitivity represents a range of dermatological conditions that are caused or exacerbated by sunlight exposure. Drug-induced photosensitivity can be seen in patients treated with all kinds of oncology treatments, including chemotherapeutic agents, targeted anticancer therapies, and immune checkpoint inhibitors. Case outline. We present a case of a patient with metastatic hormone receptor positive and HER2- metastatic breast cancer who developed phototoxic skin changes during the treatment with ribociclib/letrozole. During the treatment, the patient developed mild redness of the skin in a strict photosensitive distribution and rash changed to erythematous confluent plaques on the neck and upper part of the chest, face, and forearms. After treatment cessation the skin changes did not reappear. Conclusion. As the observed cutaneous adverse effect subsided after the treatment cessation and did not reappear after the initiation of palbociclib/letrozole treatment, it can be concluded that the adverse effects were the consequence of ribociclib action. Management of cutaneous adverse effects is different depending mostly of grade of cutaneous adverse effect and its severity.

Little is known about the population-based mismatch between phenotypic and genetic BMI (BMI-PGM) and its association with type 2 diabetes. We therefore used data from the China Kadoorie Biobank and UK Biobank and calculated BMI-PGM for each participant as the difference between the percentile for adjusted BMI at baseline and the percentile for adjusted polygenic risk score for BMI. Participants were categorized into discordantly low (BMI-PGM< the 1st quartile), concordant (the 1st quartile ≤BMI-PGMrd quartile), and discordantly high (BMI-PGM≥the 3rd quartile) groups. We calculated adjusted hazard ratios (aHRs) for the association of BMI-PGM and type 2 diabetes using Cox proportional hazard models in each cohort, and combined HRs using random-effects meta-analyses. During a median follow-up of 12 years for both cohorts, BMI-PGM was associated with the risk of type 2 diabetes, with the discordantly low group showing reduced risk and the discordantly high group showing elevated risk compared to the concordant group, independent of BMI and other conventional risk factors. In addition, normal-weight individuals with discordantly high BMI-PGM faced a higher risk of type 2 diabetes than overweight individuals.These findings suggest that BMI-PGM may play a potential role in reassessing the risk of type 2 diabetes, particularly among normal-weight populations.
Freedom, State, and Market
Authors: Hebenton Angus , O'Neill Martin
Published: December 2024

The complexity of the real history of economic planning in practice, as well as the variety of rationales that have been offered in theory for various (more or less comprehensive) forms of planning, both suggest that political philosophy would benefit from a more nuanced and less simplistic approach to the discussion of state planning of the economy. The aim of our article is to clear some ground for a discussion of markets and democratic economic planning within normative political philosophy that takes a less stark and dichotomous approach in considering the relationship between markets and state planning, and takes more account of the complexities of both the theory and historical practice of economic planning. The article considers some of the different varieties of democratic economic planning, and the rationales for different forms of imperative and indicative planning regimes, as well as other alternative planning mechanisms. In particular the article looks to bring renewed attention to the theoretical rationales for planning offered by two important theorists of the mixed economy: James Meade and Stuart Holland. We close by revisiting the powerful normative case for economic planning provided by Barbara Wootton, whose rejection of F. A. Hayek’s critique of planning, as well as her positive case for planning on grounds of freedom, democracy, and social equality, deserves to be much better known, and whose work is ripe for reintegration into contemporary normative discussions of social justice and political economy.
Exploring EFL Teachers’ Views on Task-Based Learning and English for Specific Purposes in Saudi Arabia
Authors: M. Alwahibee Khalid , Saad Al-Mutairi Awatif
Published: December 2024

This study investigates how instructors perceive Task-Based Instruction (TBI) implementation in their English for Medical Purposes (EMP) classes. There are two minor objectives: 1) to examine the degree to which EMP instructors utilize TBI in their teaching, and 2) to highlight the perceived advantages and disadvantages of TBI from the perspective of EMP instructors. To achieve these objectives, the study attempts to answer the following question: What are the EMP instructors’ views on implementing TBI? The study was carried out with 50 EMP instructors who teach medical students. It employed qualitative and quantitative methods, utilizing a questionnaire and semi-structured interviews. The findings indicated that 83% of EMP instructors had a positive attitude towards incorporating task-based instruction in their teaching practices, and 74% demonstrated a high understanding of TBI concepts. According to the instructors, TBI is advantageous and motivating for EMP students as it enhances their communication skills and promotes student interaction. The findings are followed by some implications for Teachers of English for Medical Purposes and curriculum designers to develop and implement TBI strategies for EMP students. Finally, the research concludes with some recommendations for further study.

Published: December 2024

Second-language learners of English try to master and improve their English-speaking skills. This study investigated female Saudi university students’ attitudes towards the following: a) speaking English in general; and b) speaking English with native speakers vs. non-native speakers. It can be vital to understand students’ attitudes to help them improve their ability to communicate effectively and express their thoughts clearly and easily. Data was collected from 112 female Saudi students at Taif University, using a closed-ended questionnaire and a semi-structured interview. The participants were asked about (a) their attitudes towards English speaking skills in general; (b) their attitudes to speaking English with native speakers; (c) their attitudes to speaking English with non-native speakers; and (d) how they felt about improving their English-speaking skills. Data collected by the questionnaire indicated that they were optimistic about the importance of English-speaking skills; b) had positive attitudes towards speaking with native speakers, which was not the case when they considered speaking with non-native speakers; c) felt nervous towards speaking with non-native speakers, who tended to be critical of their language skills; and d) preferred English activities to be with native rather than non-native speakers.
Empirical Study of L2 Motivation and Motivational Learning Behaviors among College Students in English for Medicine Class
Authors: Su Na , Othman Rohani , Su Hailin
Published: December 2024

This study examines the relationship between L2 motivation and motivational learning behaviors among college students enrolled in an English for Medicine course at a university in Zhejiang, China. It aims to help language teachers gain a deeper understanding of the relationship among constructs in the L2 Motivational Self System and how constructs like the Ideal L2 Self, Ought-to L2 Self, and Second Language Learning Experience influence students’ motivational learning behaviors using the L2 Motivational Self System framework. Eighty medical students were included as a sample, and a structured questionnaire was used to gather the quantitative data. Through a quantitative analysis, it is found that the students’ motivational learning behaviors are significantly predicted by both L2 motivation and Second Language Learning Experience, with a moderate influence from the Ideal L2 Self. Additionally, the Ought-to L2 Self had less impact on the students’ learning behaviors. The findings show that fostering intrinsic motivation and providing a supportive learning environment is necessary to improve students’ engagement and effort in English for medicine courses.

Movement without a movement: Food self-provisioning in Eastern Europe and the Balkans as emergent transformation towards a degrowth mode of living
Authors: Domazet Mladen , Lubbock Rowan
Published: December 2024

The intimate links between agri-food systems and degrowth economics has only recently been addressed in the extant scholarship, much of which centers on the contributions of "food self-provisioning" (FSP) as a type of (often urban and peri-urban) practice nurturing communal autonomy, healthy/organic food, and environmental sustainability. While FSP within Western Europe is often celebrated within environmentalism and agri-food studies, its practical scope remains limited. In contrast, FSP within Eastern Europe (EE) and the Balkans is widespread, yet overlooked with regards to its potential insights, or simply fetishized as a type of crisis-induced "scarcity" narrative. Echoing more critical scholarship on FSP within the EE/Balkans, we argue that FSP within this overlooked region constitutes real movement towards a degrowth paradigm. However, we seek to better understand both the potentials and limits to the politics of alternative foodways. We suggest that FSP's potential contribution to a degrowth paradigm might be enhanced by raising its voice, rather than staying silent. Drawing on a broadly Marxian approach to political economy, degrowth, and critical agrarian studies, we argue for the strategic necessity of embedding FSP practice in a context of political organization that aims to shift the balance of forces across the strategic terrain of the capital-state nexus. In doing so, we aim to shed more light on the material-economic and politico-institutional space(s) in which FSP within the EE/Balkans (and beyond) may evolve from a movement without a movement towards an emergent collection of social forces building a degrowth mode of living.
Evaluation of Prediction Performances of Deep Learning Models for the Aerodynamic Characteristics of Flettner Rotors
Authors: Seo Janghoon , Park Jung Yoon , Ma Juhwan , Kim Young Bu , Park Dong-Woo
Published: December 2024

This study investigates the prediction of the aerodynamic characteristics of Flettner rotors through three deep learning models. Various numbers of Flettner rotors, arrangements, and spin ratios are employed to consider these effects in the dataset. For the training of deep learning models, a dataset of aerodynamic force coefficients and flow fields is generated using Computational Fluid Dynamics (CFD). Three deep learning architectures (U-net, Encoder-Decoder, and Decoder models) are employed and trained to predict the aerodynamic characteristics of Flettner rotors. Three deep learning models are established through a training stage with a hyperparameter study and by altering the number of layers. The aerodynamic force coefficients and flow fields are predicted by established deep learning models and show small absolute errors compared to those from the CFD analysis. Moreover, predicted flow fields reflect the flow characteristics according to the difference of spin ratio and arrangement of Flettner rotors. In conclusion, the established deep learning models demonstrate rapid and robust predictions of aerodynamic force coefficients and flow fields for Flettner rotors under varying arrangements and spin ratios. Furthermore, a significant reduction in computational time is measured when comparing the analysis time of CFD simulations to the training and testing time of the deep learning models.

Authors: Miao Zhe , Zhao Yong , Su Shaojuan , Song Nanzhe
Published: December 2024

In this study, a comprehensive digital twin monitoring system for ship equipment was designed and implemented, including the system architecture, key technologies, and applications. Through data-driven models and operational monitoring system analysis, our PSO-SVM-based time series prediction method demonstrated excellent predictive capabilities for catamaran equipment, achieving efficient fault warnings using a threshold method. The digital twin model and virtual scenarios constructed here provide a visualisation and simulation platform for equipment status monitoring, enhanced fault diagnosis and support for maintenance decisions. The system integrates real-time monitoring, fault warning, and data analysis, and testing results show good stability and accuracy. In addition, the system optimises the user experience through multi-round feedback testing, and ensures data security and privacy protection through multi-layer encryption, identity verification, and role-based access control. A case study indicates that the proposed system effectively monitors equipment status and provides fault warnings, and has broad application prospects and practical value. Future work will focus on optimising the functionality and improving the applicability and security of the system.
Investigating the Coupling Effects of Momentum Wake-Buoyancy Jets in Thermohaline Stratification: A Simulation Study
Authors: Yongcheng Du , Changgeng Shuai , Feiyang Luo , Chengzhe Gao
Published: December 2024

This study analyses the impact of varying temperature and salinity stratifications on the thermal characteristics of the wake through a newly established simulation model, the reliability of which is confirmed by experimental validation. In a stratified environment with sTable positive salinity but a temperature changing from positive to negative, the wake has “cold” and “hot” characteristics at the free liquid surface, respectively, and these characteristics are enhanced with an increase in the temperature gradient. In a stratified environment with a sTable positive temperature but changing positive salinity, the wake stream has “cold” characteristics at the free liquid surface, and the feature intensity has a weak positive correlation with the salinity gradient. In general, under the boundary and initial conditions studied in this paper, temperature stratification is the main factor determining the thermal characteristics of the free surface, and salinity stratification is the secondary factor. The influence of the moving induced wake on the thermal characteristics of the wake is stronger than that of the buoyant jet. In a follow-up study, we will focus on a scale analysis of the impact of stratified features on the wake, and scale extrapolation. The influence of the free surface thermal boundary layer on the wake characteristics will be another key point for investigation.

This article presents a condensed outline of how approaches to solving technical diagnostics tasks have changed over the last 50 years. It reviews different approaches to the modelling of wear and tear phenomena that are the subject of diagnosis, and draws attention to groundbreaking papers which are still of topical interest. Particular emphasis is placed on the development of vibroacoustic diagnostics methods, an area in which Polish scientists were among the world’s avant garde. It is also shown how methodologies have changed with the progress of digital signal analysis. The example presented in the second part of the article demonstrates that the well-known and technically important task of diagnosing a gear set can now be solved without looking for a classic state→symptom relationship through an accurate dynamic description of the machine and comparing it with the results of an experiment, but instead by comparing observations at different points in the n-dimensional space with an abstract pattern generated by a sequence of logical transformations. This formulation of the task opens up avenues for AI methods. Attention is paid to the fact that maritime shipping is one of the main fields of application for modern diagnostic methods, and it is shown that the increase in the accuracy of vibroacoustic diagnostics techniques and the correctness of the diagnosis allows for the use of this methodology in marine applications.

The stern tube or strat bearings are key important component for safety of shipping. Modern global regulations required a low as possible negative impact on environment including lubricants leaking to the sea. The ship owners are looking for reliable and durable solutions. The costs of each ship components are carefully studied. The water lubricated bearings for ship propeller shafts are an environmentally friendly solution. That is the reason why water lubrication is an interesting option to consider. Because simplicity of the ship design is expected the open lubricating system with only one seal module, when sea water is a lubricant is often recommended by manufacturer.

This research was inspired by a series of failures or premature excessive wear of the propeller shaft strut bearings of real ships. The experimental tests were conducted in the laboratory on custom designed and build test-rig. The large group of tested bearings was delivered by certified manufacturers.

The results of long time wear tests clearly prove that the cause of this premature wear was abrasive wear resulting from water contamination with solid particles of mineral origin. The range of the wear strongly depends on bearing bush materials and bearing interspace geometry. The wear was low for bearings with elastic bushes especially when hydrodynamic phenomena takes place.

The general conclusion is that water lubrication is an interesting option to consider when design of the ship is discussed. The simplicity resulting an attractive price, low maintenance costs and proven durability and reliability of some bearings materials cause that this technology is becoming popular and often applied.
Effect of Vitamin D Supplementation on Serum Lipid Profile in Patients With Cardiovascular Risk

Published: December 2024

Introduction

Existing evidence suggests vitamin D may benefit serum lipid profiles and, thus, cardiovascular health. The present study aimed to evaluate the effect of oral daily vitamin D supplementation on lipid profile among patients with cardiovascular risk.

Material and Methods

A total of 154 patients were included in the study, aged over 18 years, with at least one cardiovascular risk factor. Blood samples were collected at baseline and a 6-month follow-up. About 100 patients received vitamin D supplements in addition to the statin treatment, and 54 benefited from oral vitamin D treatment only.

Results

The serum level of vitamin D showed a significant increase after 6 months of treatment: from a mean basal level of 18.5 ng/ml (± 9.0) to a mean level at 6 months of 43.1 ng/ml (± 9.5) – p<0,0001. In the group treated only with vitamin D supplements, a significant improvement was observed in the total cholesterol and LDL cholesterol levels, even if the patients did not benefit from statin treatment. Among patients who also received statins, differences were observed in changes in serum LDL cholesterol, HDL cholesterol, and triglycerides, in that the decreases observed were more pronounced than those who received only vitamin supplementation D.

Conclusion

Vitamin D supplementation appeared to have a beneficial effect on lipid profile. Vitamin D supplementation may be useful in dyslipidemia patients at high risk of cardiovascular diseases.
The Amazon in the Context of the Climate Crisis: the Contradiction Between the Environmental Emergency and the Economic Interests
Authors: Oliveira Manoela Hoffmann , Oliveira Anna Hoffmann
Published: December 2024

Objective: This article, through a critically sociological and interdisciplinarily grounded analysis of the environmental crisis, presents the intricate mechanisms within the economic, political, and legal domains that Lula’s government must confront in the context of Amazonian destruction.
 
Theoretical Framework: Despite the social and scientific recognition, the historical dimension of the gravity of the climatic situation, and the disastrous consequences of Amazon deforestation, the socioeconomic mechanisms that hinder the resolution of this collapsing scenario have not yet been adequately addressed nor entirely comprehended.
Method: The study considered up-to-date qualitative and quantitative data obtained from bibliographical and documentary research in reputable national and international sources.
 
Results and Discussion: The deforestation rate within the biome is declining; however, the state environmental policy maintains its rate in its energy plan with new oil wells, regularization of illegally acquired lands, and projects such as a railway crossing the forest, all questioned by the Minister of the Environment, Marina Silva. A pivotal aspect regarding Brazil, which prevailed during Lula’s term and several governments, is land concentration.
 
Research Implications: Although the current government, in contrast to its predecessor, has promised to engage in a conservationist revival of the forest, primarily focusing on eradicating deforestation and enforcing and rebuilding climate diplomacy, it is crucial to acknowledge the significant limitations of this attempt.
 
Originality/Value: The destruction of the Amazon presents itself as a necessity and constitutes a method that better serves an economic objective than socio-environmental sustainability. Clarity regarding these matters must fundamentally underlie the anticipation of realistic scenarios, all studies, and policies for mitigating and adapting to climate change.
L’adieu aux ordres - Les sécularisations des religieuses au moment de la Réforme (France – Suisse – Angleterre, XVIe siècle)
Authors: Guillemard Éléna
Published: December 2024

Au XVIe siècle, à la suite des remises en question protestantes de la vie monastique, des religieuses se retrouvent hors du couvent en France, en Suisse et en Angleterre. Certains itinéraires de vie montrent la difficulté de la nécessaire adaptation au monde qui s’ensuit. En effet, la marge de manœuvre des anciennes religieuses est souvent restreinte : d’un côté, des femmes de la grande noblesse, telle Charlotte de Bourbon, sortent du couvent pour retrouver leur position sociale ; de l’autre, des femmes issues de familles aux origines sociales variées affrontent le retour au siècle sans soutien. Que deviennent ces femmes ? Quelles formes prend leur sécularisation ? Contrairement à une idée reçue, le mariage, encouragé par les protestants, n’est pas la première option retenue par ces femmes en rupture de cloître. Les anciennes religieuses doivent alors réinventer leur itinéraire de vie, dans des contextes souvent ardus.
Van Gogh in Paris - Malerei und Ausdruck in der Moderne
Authors: Misteli David
Published: December 2024

Während Manet oder Cézanne als wichtige Modernisten gelten, deren Werk ihr Umfeld, die Geschichte und die historischen Bedingungen der Malerei der Moderne beleuchtet, wird Vincent van Goghs kunsthistorische Bedeutung außerhalb seiner Zeit verortet, in der Zukunft der Moderne, die sich auf ihn als Vaterfigur beruft. Es fehlt eine Sicht auf van Gogh, von der die Kunstgeschichte etwas über die Herausforderungen und Probleme der modernen Malerei in der zweiten Hälfte des 19. Jahrhunderts lernen kann. Diese Lücke schließt das Buch. Von van Goghs erstem Auftritt im Salon des Indépendants bis zu seiner Beschäftigung mit der Topografie des Montmartre entwickelt es anhand von detaillierten Bildlektüren, neuem Quellenmaterial und bisher unbeachteten theoretischen Zusammenhängen ein neues Verständnis des Malers. Es geht um die Reflexion einer tiefen Krise in der Malerei der Moderne über die Expressivität der Kunst und um das Aushandeln der Glaubwürdigkeit der Malerin oder des Malers als Subjekt des Ausdrucks. Dazu schenkt das Buch dem bislang wenig wahrgenommenen Pariser Œuvre erstmals die Aufmerksamkeit, die ihm malereigeschichtlich gebührt.Ausgezeichnet mit dem Fakultätspreis der Philosophisch-Historischen Fakultät der Universität Basel.
Philosophische Terminologie und Ambiguität in Lukrez’ Lehrgedicht De rerum natura
Authors: Borchers Sonja K.
Published: December 2024

In der Geschichte der römischen Literatur bietet Lukrez’ Lehrgedicht De rerum natura den ersten Text, an dem sich die Beschreibung philosophischer Sachverhalte und die Entwicklung einer lateinischen philosophischen Terminologie genau beobachten lässt. Die philosophische Terminologiebildung bei Lukrez erscheint dabei als Resultat eines Transformationsprozesses der epikureischen Terminologie aus dem Griechischen ins Lateinische. Den Spuren dieser Transformation geht die vorliegende Arbeit exemplarisch anhand einer Reihe detaillierter Einzelstudien nach, die vor dem Hintergrund der epikureischen Sprachtheorie eingeordnet werden. Dabei wird gezeigt, dass Lukrez Phänomene der Ambiguität und Mehrdeutigkeit im Kontext der epikureischen Philosophie gezielt zur Wissensvermittlung einsetzt. Es ergibt sich eine neue Sicht auf die sprachliche Gestaltung des Werkes.
