Published: January 2025

Building Information Modeling (BIM) is recognized as a sustainable approach to the development of architecture and engineering projects, operating at all phases of a building's life cycle. Despite its importance, the adoption of BIM in education has been gradual. The aim of this article is to investigate the adoption of BIM software by civil engineering students at the Polytechnic School of the University of Pernambuco (POLI/UPE) in the architecture course, taught in the 6th semester. The longitudinal study encompassed quantitative data from 2020 to 2023, aiming to classify the delivered projects according to the software used (2D or BIM), identify temporal trends in the use of BIM software, and develop hypotheses to understand the reasons for the software choice. It was observed that the use of 2D software was predominant among students in 2020, with 63.95% usage, but there was a gradual increase in the adoption of BIM software over time, becoming significant in 2023, with 80.85% usage. This study contributes to the understanding of the dynamics related to the integration of BIM in academic training in Civil Engineering, highlighting the role of the university as a promoter of sustainable practices in the construction industry, emphasizing the importance of BIM as a tool for efficiency and quality throughout the building life cycle.

Authors: Dumingues Elaide , Sato Anderson Mululo , Finotti Ricardo
Published: January 2025

This study evaluates a Rain Water Harvesting (RWH) system considering its social, economic, and ecological aspects. We constructed a prototype at a metallurgical industry in Bom Jardim municipality, Rio de Janeiro state, Brazil, that uses rain water for sanitary purposes. The prototype has the same characteristics of the industry roof such as materials, positioning, and similar inclination. The rainfall and runoff volume were measured and water was also collected in periods when there was no rainfall to assess the amount of atmospheric water condensation collected (dew water). A thermo-hygrometer was used to note the local air relative humidity and temperature every day. We also conducted a survey on the costs to build the entire system and applied a survey to it employees, to estimate water savings. Collected rainwater was analyzed to the following parameters: turbidity, pH, nitrate, nitrite, orthophosphate, silicate, ammonia, organic matter, total coliform and E. coli. The roof had a mean flow coefficient of 88%, which resulted for the roof area (3,940m²) a mean of 28,354.04±44,674.86L. The uptake of water by atmospheric condensation can reach 2,469 liters on a day and it is positively correlated with the minimal temperature. The system payback time was estimated in 10 years. However, given the quality of the water, this system could be in use for other purposes, which would increase water savings and reduce the payback time.
The Authenticity of Metaphysics Alpha elatton in the scholium Parisinum and in Alexander of Aphrodisias’ recensio altera
Authors: Folli Laura
Published: January 2025

The present note offers a brief new analysis of the well-known scholium found in codex Parisinus gr. 1853 (E) on folio 234r. My analysis will compare it to the exegetical approach that Alexander of Aphrodisias adopts at the outset of Alpha elatton – attested by two different recensiones – and to Asclepius’ exegesis of the first lemma of Aristotle’s Metaphysics.
Aristotle’s Earliest Extant Manuscripts. New Doubts and Perspectives
Authors: Fazzo Silvia
Published: January 2025

This paper follows up on two previous contributions in Aristotelica (3 and 5) that focused on the early transmission of Phys. 250b13 as a case study. Here, the discussion broadens to general questions about the scribal hands behind Aristotle’s earliest manuscripts J (ms. Vindobonensis Phil. gr. 100) and E (ms. Parisinus gr. 1853), their roles in textual history, and their connections to the earliest reconstructable archetype. Current scholarship holds that while the sources of J and E overlap for the Metaphysics (labeled Π by Jaeger’s 1957 critical apparatus), they diverge entirely for the other works held by both codices, i.e. Physics, De caelo, De generatione et corruptione, Meteorology. How can this be explained? A major, recent development is Ronconi’s (2012) identification of two distinct tenth-century volumes later combined into ms. E. Each has a main early scribe at work. Thereafter, no attempt has been made to differentiate their approaches to the text. In Aristotelica 5, E’s two early scribes are distinguished and labeled, the one, EMet (responsible for the Metaphysics) the other, EPhys (responsible for the Corpus Physicum). The two exhibit differing approaches. Through closer analysis of their methodologies, it is possible to investigate and eventually to detect what I call a “β agenda” in EPhys’s Corpus Physicum, by analogy with the socalled β manuscripts of the Metaphysics.

Authors: Enninful Archibald , Fan Rong , Farzad Negin
Published: January 2025

This protocol describes the use of Deterministic Barcoding in Tissue for spatial omics sequencing (DBiT-seq) platform to construct a multi-omics atlas on FFPE tissue samples. This approach uses a microfluidic-based method to introduce combinatorial DNA oligo barcodes directly to the cells in a tissue section on a glass slide. This technique does not directly resolve single cells but can achieve a near-single-cell resolution for spatial transcriptomics. This protocol is adapted from the Patho-DBiT publication - Spatially exploring RNA biology in archival formalin fixed paraffin-embedded tissues (Bai et al., 2024, Cell 187, 6760–6779)

Authors: Salihi Viola , Rexhepi Sadije
Published: January 2025

Understanding common errors that students of a foreign language make and their causes can enhance our ability to adjust teaching methodologies. This paper aimed to analyze errors that Albanian students of German language and literature make when writing texts in German as a foreign language. This qualitative and quantitative analysis set out to identify and classify errors and find the causes of errors. The study is based on 100 students of German at the B1 level, including participants from language schools and first-year students from the German Department at the University of Prishtina “Hasan Prishtina”. Students were required to submit written texts for analysis. The analysis of these texts was used to address the following research question: What are the typical and recurrent errors made by learners of German as a foreign language (GFL) and what are their causes? The analysis of written texts showed that errors occur at all linguistic levels, with grammatical errors being the most common, followed by orthography and punctuation and syntax. Most errors arose from interference between the native Albanian and the foreign language English, followed by competence and overgeneralization.
The Concept of Dream as a Technique of Resistant Consciousness and Emancipation in the Poetry of Langston Hughes and Mahmoud Darwish
Authors: Alshawabkeh Nawal , Almahasneh Hamzeh
Published: January 2025

This paper aims to examine the concept of dream in the poetry of Langston Hughes and Mahmoud Darwish as a technique of resistant consciousness and emancipation. The intransigent, non-reconciliatory stance of both Darwish and Hughes against oppression profoundly preserves their dream of emancipation, making it alive even as an idea. The dream empowers the two poets’ resilience, oppositional, and resistant consciousness against all forms of oppressive power. This article analyzes how both Darwish and Hughes can be viewed as non-reconciled poets in the name of humanist intransigence and refusal to surrender. The concept of dream is the ultimate way for the two poets, providing them with radical and oppositional resistance. Hence, the presence of the concept of dream and its prevalence in the two poets’ thinking and poetic works encourage them to be always in a state of dynamic generative mobility of resistance, intransigence, and non-reconciliation.

Authors: Suárez Valeria
Published: January 2025

Despite regulatory frameworks that protect the rights of people with disabilities, accessibility and participation in culture and the arts remain limited. This study employs a qualitative approach within the socio-critical paradigm and a Participatory Action Research design to interpret and evaluate proposals from participants, expert teachers, and the researcher regarding ways to democratize theater for people with cognitive disabilities. The goal is to move towards an inclusive environment that enhances socio-emotional learning, expression, and cognitive development. Information was collected from semi-structured interviews with a group of actors and actresses with disabilities, as well as theater teachers. This data facilitated the development of the Action Proposal for the Democratization of Theater. The findings revealed that theater can significantly improve the quality of life for people with cognitive disabilities by providing them with a space for expression, personal learning, and social development. Barriers to access and participation were identified, highlighting the urgency of promoting authentic representation and driving social change towards a more inclusive world.

Published: January 2025

Malaysia’s tropical climate, alternating wet and dry conditions, and high rainfall contribute to soil erosion issues and landslide risk. Soil bioengineering techniques are among the approaches that can be adopted to tackle these issues and reinforce hillslopes. However, selecting appropriate species for bioengineering applications is crucial. Besides the growth of selected plant species, the root tensile strength also plays an important role in soil structure improvement. This research investigated the growth and root characteristics of four potential shrub species namely Strobilanthes crispa (SC), Tabernaemontana divaricata (TD), Pseuderanthemum carruthersii (PC), and Hibiscus rosa-sinensis(HR) as a plant bioengineering material by determining their root tensile force and stress after six months of growth. The soil medium for plant propagation was prepared using a 3:1:1:1 ratio of soil, sand, organic materials, and chicken manure and used for planting the shrub species for 6 months of monitoring. The results show that SC and HR species exhibit superior growth performance in most variables. Root diameter influences mechanical properties of tensile force and stress which can be best presented by power-law equation. TD species has the strongest root for tensile stress, followed by species HR, PC, and SC. All the selected species have potential as biological material in terms of growth performance and root tensile strength. However, further study is essential to evaluate the survivability and root tensile strength of the selected shrubs when implemented on real slopes. This would offer genuine insights into the specific characteristics of their root systems under practical conditions.

Published: January 2025

The high demand for garlic (Allium sativum L.) has led to efforts to improve its productivity. Garlic endophytic bacteria have been found to boost the growth of garlic plants and protect them from diseases without any harmful effects on the host. The objective of the study was to isolate and characterise the endophytic bacteria present in the healthy local Indonesian garlic variety ‘Tawangmangu Baru’ towards developing them as plant growth-promoting bacteria in improving garlic quality and productivity. The isolation of endophytic bacteria was performed from garlic leaves and roots during the vegetative phase. A total of 20 endophytic bacteria isolated from garlic leaves and roots were characterised by their morphology and tested for their ability to fix nitrogen (N), produce auxin (IAA), and solubilise phosphate. All the isolates were able to fix nitrogen, with 15 of the isolates found to be Gram-positive having bacilli cell shape. Furthermore, 8 isolates were shown to produce auxin, while 10 isolates were able to solubilise phosphate, with both groups originating from the root sample. Five potential isolates were identified as nitrogen-fixing, IAA-producing, and phosphate-solubilising, with the highest values of IAA concentration and the Phosphate Solubilisation Index (PSI) being 10.71 ppm and 2.00, respectively. These 5 potential endophytic bacterial isolates were genetically identified as similar to Lysobacter tolerans, Enterobacter cloacae, Enterobacter huaxiensis, Klebsiella oxytoca, and Enterobacter hormaechei. The potential endophytic bacterial isolates hold promise for developing garlic plant growth-promoting bacteria (PGPB) to enhance garlic production both qualitatively and quantitatively.

Published: January 2025

17ß-estradiol (E2) adalah sejenis bahan kimia pengganggu endokrin (EDC) yang sering dikaji kerana sebatian ini banyak dikumuhkan oleh manusia melalui proses perkumuhan dan dilepaskan kembali ke dalam sistem air tanpa dipantau oleh loji rawatan air. Tahap E2 yang tidak normal boleh menyebabkan masalah kesihatan seperti tulang lemah (osteoporosis) dan masalah kesuburan disebabkan oleh ketidakseimbangan hormon. Untuk memastikan pengesanan awal dan pengurusan yang betul bagi keadaan ini, biopengesanan berterusan terhadap tahap E2 adalah penting untuk mengekalkan keseimbangan hormon dan kesihatan keseluruhan. Pendekatan alternatif telah diambil dengan menggabungkan sensor elektrokimia dengan 76-mer aptamer yang mempunyai rantaian khusus E2 yang telah terbukti mempunyai keafinan tinggi kepada E2. Polimer metakrilat-akrilat dengan struktur mikrosfera telah digunakan untuk meningkatkan kepekatan aptamer yang dipegun dan meningkatkan kepekaan sensor tanpa memerlukan amplifikasi oleh bahan konduktif. Penyelidikan ini telah membangunkan biosensor elektrokimia untuk mengesan 17ß-estradiol (E2) menggunakan polimer metakrilat-akrilat yang diubah suai. Polimer poli(glisidil metakrilat-ko-n-butil akrilat) terfungsi dengan nisbah isi padu 90:10 dalam bentuk mikrosfera bertindak sebagai matriks untuk pemegunan E2-aptamer secara kovalen. Berdasarkan analisis elektrokimia, biosensor 17ß-estradiol (E2) yang dibangunkan berasaskan aptamer ini telah berjaya menunjukkan julat kepekaan linear antara 0.1 nM - 1.0 µM (R2 = 0.9937) dan had pengesanan rendah sebanyak 7.384 pM. Kebolehasilan biosensor (n=8) diperoleh ialah antara 2.65% - 12.23% dan adalah selektif terhadap molekul E2 berbanding dengan tindak balas terhadap sebatian EDC yang lain. Selain itu, biosensor yang dihasilkan telah berjaya mengesan kepekatan E2 yang ditambah ke dalam sampel air sungai dengan peratusan pemulihan yang tinggi di antara 92.5 dan 97.2%. Oleh itu, biosensor yang dibangunkan ini berfungsi dengan baik dalam mengesan dan memantau kepekatan E2 dalam sampel air.
A Double-Edged Sword Effect of Angiogenesis in Hypertension: A Review
Authors: AD Noor Hasila , NH Nur Syahidah , AH Adila , Yazid Farinawati , MA Nur Najmi
Published: January 2025

Hypertension, commonly known as high blood pressure, is a serious medical condition that significantly raises the risk of heart, brain, kidney, and blood vessel diseases. It remains one of the leading causes of morbidity and mortality worldwide, with its mechanisms still not fully understood. One emerging area of interest is the role of angiogenesis, the formation of new blood vessels, which is regulated by a delicate balance between pro- and anti-angiogenic modulators, including angiogenic factors, extracellular matrix proteins, adhesion receptors, and proteolytic enzymes. Disruption of this balance can lead to abnormal angiogenesis, potentially contributing to hypertension, as angiogenic growth factors are critical in maintaining vascular structure. If left untreated, high blood pressure damages capillaries and microvessels, accelerating the process of vascular rarefaction. Notably, microvascular rarefaction may occur independently of changes in blood pressure, indicating its potential role as a primary factor in hypertension progression. The ‘double-edged sword effect’ describes the paradoxical impact of both pro- and anti-angiogenic therapies, where either type of drug can induce hypertension, highlighting the dual nature of angiogenic regulation in vascular health. Given the rising use of angiogenesis-modulating therapies in treating various diseases, therapy-induced hypertension is expected to become more prevalent. This review was conducted to address the growing need to understand this dual effect of angiogenic therapies, the mechanisms underlying hypertension development, and the critical importance of early detection and long-term management of hypertension in patients undergoing such treatments.

BANDEIRA NEGRA E CORPO NEGRO:
Authors: Freire Rodrigues Danilo
Published: January 2025

Este artigo tem como objetivo principal resgatar a história de quatro anarquistas brasileiros e, racialmente, “de cor”. Através desses quatro exemplos biográficos, este trabalho demonstra que não foram apenas trabalhadores imigrantes europeus que estiveram presentes e atuantes nos movimentos revolucionários ligados à classe operária nacional: esses quatro brasileiros “de cor” – Eustáquio Marinho, Lima Barreto, Domingos Passos e Cândido Costa – foram militantes anarquistas a seu modo, seja através do movimento operário e sindical, seja através da difusão de ideais, críticas, livros, artigos, etc. Além disso, a história desses quatro libertários desmente a noção de “radicalidade” e ação revolucionária atribuída aos trabalhadores imigrantes europeus e de “passividade”, “aceitação” e “colaboração” atribuída à massa trabalhadora nacional.

“LA BARBARIDAD NO ES TANTA”
Authors: Stori Bruno
Published: January 2025

O presente artigo consiste em uma discussão sobre os discursos de racialização dos povos “tártaros” no século XVII a partir do Novus Atlas Sinensis (1655), ou Novo Atlas Sínico, confeccionado pelo jesuíta Martino Martini. Por meio de uma análise das descrições etnográficas presentes no atlas, que detalham costumes e fenótipos de diferentes sociedades do Leste Asiático, apontamos as tentativas do autor em minimizar a barbárie e a violência atribuídas a grupos vindos da Manchúria, que, à época, haviam invadido a China e estabelecido a dinastia Qing. Propomos que Martini efetuou um processo de racialização dos manchus – chamados “tártaros” –, tendo como base critérios geográficos, culturais e ambientais que demonstram a maleabilidade e heterogeneidade intrínsecas às narrativas de categorização de populações humanas antes do surgimento da ideia “moderna” de raça.

Published: January 2025

A partir da figura do artista Modesto Brocos, este artigo tem como proposta refletir sobre algumas questões que giram em torno das trajetórias de sujeitos históricos que tocaram em temas sensíveis, como os debates acerca de raça. Naturalizado brasileiro, Brocos foi pintor na passagem do século XIX para o XX, ganhando destaque pela pintura A Redenção de Cam, tela apresentada ao público em 1895. O texto inicialmente remonta a história de vida do artista, biografia pouco estudada em comparação aos seus contemporâneos. Depois, aborda como a questão racial foi mesclada com a trajetória do artista, ocultando parte de sua história e idiossincrasias. Por último, e tendo em vista contribuir para o debate historiográfico sobre biografias, reflete a produção científica diante das perguntas do tempo presente na presença do passado, tema que os historiadores têm frequentemente se voltado.

In light of India's rapidly ageing population, projected to make up 40% of the population by 2050, this study uses information from the Longitudinal Ageing Study in India (LASI) to examine how Household Environment Condition (HEC) affects the health of older adults. By concentrating on biomarkers, the research seeks to understand how these health indicators are spread across different states and their connections to household facilities. The results are expected to offer detailed viewpoints for policy actions, helping improve living conditions and health for the elderly in India.

The aim of this study is to explore the access of household facilities of older people from different states in India and to check the association between the available household facilities and biomarkers.

This study used data from the Longitudinal Ageing Survey of India (LASI), executed in 2017-18 where 24,323 individuals with biomarkers specifically collected from those aged 60 years and above. The analysis, employs various statistical techniques, including descriptive analysis, correlation analysis, and hypothesis testing, providing a robust methodology to explore the intricate relationships between biomarkers and household facilities among the elderly population in India.

Significant variations were observed in body mass index, systolic blood pressure, waist-to-hip ratio, and grip strength between the male and female cohorts. Positive associations were observed between housing and cooking fuel, housing and a separate kitchen, and cooking fuel and a separate kitchen. However, a negative correlation was noted between housing and safe water, suggesting a potential trade-off.

Significant correlations between household amenities and health biomarkers suggest a potential influence of living conditions on health outcomes in the elderly citizens of India. This study highlights diverse demographic and health characteristics, emphasizing the urgent need for interventions addressing educational gaps, economic disparities, and health inequalities among the elderly in India for overall well-being of ageing population.

A significant increase in sudden heart attacks among Indian men under 50 years old has been observed nationwide. Survival from cardiac arrest largely depends on how quickly CPR is started and the quality of CPR given. People who receive effective bystander CPR are 2-3 times more likely to survive, but many people lack the knowledge to recognize or respond to a cardiac arrest emergency especially in rural India. This research examines the effectiveness of Hands-Only CPR training in enhancing schoolchildren's knowledge, attitudes, and responses in rural India.

To investigate effects of Hands-Only CPR training on CPR knowledge in school girls, investigate effects of Hands-Only CPR training on the willingness, attitudes, & intentions toward helping others and performing CPR and assess the potential of targeted educational interventions at schools, to improve community response in cardiac emergencies and improving survival rates.

Setting- girls’ High school in Barela, a rural town with limited resources in the Jabalpur District. The Cross-sectional Pre and Post intervention study took place at P.M. SHRI Government Higher Secondary School for Girls in Barela, Jabalpur, Madhya Pradesh, a rural town with limited resources in the Jabalpur District. Study Design- The Cross-sectional Pre and Post intervention study to obtain quantitative data on the effectiveness of the educational intervention of Hands Only CPR. Pre-training and post-training assessments were used to measure changes in the participants' knowledge, attitudes, and willingness to perform CPR.

None of the participants knew what CPR or Basic Life Support was prior to the training. Significant improvement was noted on knowledge towards recognizing signs of life, steps of Hands only CPR amongst the participants. Comfort on performing CPR and willingness to help during cardiac emergencies after the CPR training significantly improved

Our study identifies a notable gap in the awareness and preparedness of the students, highlighting the need for comprehensive CPR training programs at a high school level in rural India, to improve public health outcomes. Our study suggest that targeted educational interventions could empower communities and reduce the impact of cardiac emergencies.

La Renuncia al Recurso de Anulación contra el Laudo en el Arbitraje Comercial
Authors: Zuleta Londoño Alberto
Published: January 2025

Todo laudo puede escapar al control judicial. Basta que las partes se abstengan de utilizar los recursos que les ofrece la ley para impugnarlo, y que cumplan voluntariamente con la decisión del tribunal arbitral. Si esto es así, ¿por qué parecen tan reticentes la comunidad arbitral y las legislaciones aplicables en aceptar que las partes pacten de antemano la exclusión del control judicial, es decir, que lo hagan antes de la expedición del laudo? El presente artículo tiene como contexto esta pregunta y en él se explora el marco conceptual y legal del arbitraje en cuanto a la posibilidad de renuncia del recurso de anulación, o su equivalente.

Hacia un nuevo Derecho económico internacional
Authors: De Trazegnies Granda Fernando
Published: January 2025

No cabe duda de que las tendencias sociales y económicas contemporáneas están obligando a una revisión de la identidad y de los alcances del Derecho Civil, vinculándolo cada vez más a las normas sobre las actividades mercantiles. De hecho, algunas legislaciones contemporáneas, como la italiana, han incluido al Derecho Comercial dentro del Código Civil. Más allá de opinar si esta inclusión es correcta o no, no puedo dejar de pronunciarme en el sentido de que -ya sea que existan dos Códigos o uno solo- el Derecho Civil y el Derecho Comercial representan ambos el punto de vista y las preocupaciones del ciudadano privado.
Arbitrabilidad de Actos Administrativos Contractuales
Authors: Larrea Naranjo Francisco Santiago
Published: January 2025

En Ecuador existen normas legales que otorgan al Estado la potestad para acudir al arbitraje, lo cual nos ha llevado a analizar la arbitrabilidad de las disputas en el arbitraje administrativo, concluyendo que si existe una norma que expresamente permita al Estado acudir al arbitraje, este podrá hacerlo sin más obstáculos que los límites impuestos por la propia ley y el convenio arbitral, siendo el tribunal arbitral quien decidirá su propia competencia; sin que, por el mero hecho de que la disputa tenga que ver con normas de interés general –como sería la legalidad de los actos administrativos– sea un límite para el arbitraje. Los actos administrativos contractuales sí serían arbitrables, debido a que la arbitrabilidad de los mismos nace del ejercicio de una potestad otorgada por la ley y el único límite a su arbitrabilidad deberá encontrarse en la misma ley que establece la potestad de arbitrar o en el convenio arbitral; por lo que, los árbitros están obligados a respetar el principio de legalidad en cuanto a esta potestad de arbitrar, estando facultados a revisar su legalidad. Igualmente, esta arbitrabilidad no estaría limitada por la transigibilidad de la disputa. La transigibilidad, como límite a la autonomía de la voluntad, carece de sentido en el arbitraje administrativo.

Published: January 2025

Objective: this study carries out pattern identification in a sample of 16 major and emerging economies in function of their economic policy uncertainty.

Methodology: this paper applies for the groping procedure K-Means, Agglomerative Hierarchical Clustering (AHC), and Clustering and Density-Based Spatial Clustering with Noise (DBSCAN). Data: This research uses the Economic Policy Uncertainty (EPU) Index calculated monthly by the EPU Agency for several countries. In particular, it examines EPU indexes for a sample 16 countries in five crisis periods between 2008 and 2024; the sample was chosen based on data availability.

Results: global crises have created distinct country clusters transcending traditional economic groupings based on development status or geographical location. Notably, in the COVID-19 pandemic it generated an unprecedented global EPU homogeneity among countries. High-uncertainty clusters consistently emerge, often comprising large economies directly affected by crises.

Limitations: there are possible biases in news-based component of EPU indices.

Originality: to the best of the authors’ knowledge, multiple clustering techniques for various crisis periods have not been implemented before.

Conclusion: global crises can equalize policy uncertainty, challenging conventional notions of economic resilience. The empirical findings emphasize the importance of considering EPU in a global context for those responsible for improving the design of economic policy.
