Authors: Collazos-Arias Felipe , Parra-Ruíz Laura , Pertierra-Rodriguez Marta , López-Oliver David
Published: January 2025

Although there are numerous projects and references related to the assessment of risks linked to climate change in general, the implementation of specific studies in road networks or sections is not, nowadays, simple. In this regard, the World Road Association (PIARC) has been working since 2015 on the development of a methodological framework to facilitate the inclusion of climate change considerations in the planning, design, construction, maintenance and operation of road infrastructure in different countries. This methodological framework has been adapted for the Spanish case by the ATC Working Group on "Climate Change and Resilience in Roads" and will be published soon, ensuring its consistency with international and European references on the subject.The methodology described above should be applied to the different assets of the road network.In the case of bridges, the methodological application requires the particularization of impacts, hazards and structures sensitivity matrix, for which a series of case studies will be analyzed. Special attention will be paid to the study of temperatures and intense precipitation in the area. The methodological application aims at the adoption of an adaptation plan to increase the resilience of the structures of our network.

Authors: Rajić Andrea , Lukačević Ivan , Curkovic Ivan , Žuvelek Vlaho
Published: January 2025

Except for the main advantage of the composite system, which is the high utilisation of applied materials, these structural systems are also known for reusability, high degree of prefabrication and long-span capability. This paper presents experimentally supported numerical research on the bending behaviour of LWT-FLOOR composite cold-formed steel-concrete beams where steel beam elements are connected using spot-welding technology and are connected to a concrete slab by innovative demountable shear connectors. To consider the functional requirements of the system, a parametric study of LWT-FLOOR beams with different shapes of web openings is presented. Furthermore, the influence of different web openings is verified for various corrugated web thicknesses. Except for various shapes of web openings, spans of steel-concrete composite beams of 6 and 12 m are considered. For all analysed parameters, the bending capacities are compared.

Authors: Kim Soomin , Hwang Youchan , Kim Jeong-Gon , Kim Ho-Kyung , Jin Chungkuk
Published: January 2025

A floating bridge differs from conventional bridges in that both wind and wave loads act as primary dynamic loads. The nonlinear interaction between the floating body's hydrodynamic response and the bridge deck's aeroelastic response can significantly affect the entire system. However, existing commercial software lacks the capability to perform fully coupled aero-hydrodynamic analysis. Therefore, this study introduces a time-domain aero-hydrodynamic coupled analysis module for floating structures implemented through the ABAQUS User Subroutine. Validation of the developed method was achieved by comparing the response spectrum and RMS obtained from frequency- domain analysis. The developed time-domain aero-hydrodynamic analysis method enables potential possibility in future research, particularly for coupled aero-hydrodynamic analysis of long- span floating bridges.
Multi-Level Above and Below Ground Parking Structures; Capital Project Improvement using Building Information Modeling BIM (Revit, Infraworks & Leica 3D Scan Models.)
Authors: Labor Adrian Q.
Published: January 2025

The rehabilitation and adaptation of existing multi-level parking structures to meet the emerging requirements for arrays of electric vehicle (EV) charging stations on any level as well as roof-Level solar canopies is the current capital improvement goal of the Parking Management Division of the Department of Transportation, Montgomery County, Maryland, USA (MCDOT). In this changing world, the engineering management strategies to adapt the parking facilities for EV charging includes; a) structural rehabilitation to meet deterioration of aging facilities, b) structural modifications to meet new loading conditions in drive aisle and parking bays due to EV charging patterns, c) safety installations to manage the increased electrical components on the parking floors, and d) Rethinking fire suppression systems and fire-retardant application on the structure to mitigate potential hazards from high EV battery concentration. There are many scenarios that will require many assessments and redesigns to achieve structural, mechanical, electrical, plumbing and communication adaptations in over 23 above-ground and below-ground parking facilities of MCDOT. To support this effort, the team is employing 3D engineering multi-discipline design workflows developed in last few years. This leverages Building Information Modeling (BIM) applications, such as Revit Models and 3D Scan models of the parking structures as well as Infraworks models of the properties, environment and adjacent areas. Different adaptation scenarios are created and evaluated through collaborative BIM workflows involving in-house staff and local engineering firms. These efforts are guided by MCDOT’s mission and vision to be forward-thinking, embrace technology and innovation, and develop creative solutions to transportation challenges that will serve well into the future. This paper shares the strategies developed, highlights key designing aspects, and showcases the collaborative workflow and the depth of parking structure design models (Revit and Infraworks) and the survey model (Leica 3D Scan) created to date.
Portable depth sensing with the iPhone time-of-flight LiDAR
Authors: Tondo Gledson Rodrigo , Morgenthal Guido , Riley Charles
Published: January 2025

Modern smartphones offer diverse features, including ample storage, wireless data transfer, and various sensors, making them valuable for structural data collection. This study investigates the iPhone's LiDAR system for depth data collection, defining its field of view and assessing its performance for static and dynamic targets. We analyse limitations such as phone-to-target distance and noise properties. Measurement comparisons with a laser displacement transducer are conducted under different conditions to characterise the sensor’s properties. Discussions on the results include insights into Apple's AI-based sensor fusion framework, which enhances data resolution but potentially compromises accuracy in dynamic measurements. We demonstrate the system's practicality through modal analysis of a steel cantilever, revealing potential for bridge inspection and autonomous structural diagnostics via non-contact vibration sensing.
Structural Performance and Failure Modes of Cantilevered Porcelain Posts in Overhead Railway Transmission Lines
Authors: Agüero Barrantes Pablo , Hain Alexandra
Published: January 2025

Electrical insulators play a crucial role in power transmission lines by preventing undesired current flow. In certain applications, such as overhead railway lines, these insulators also serve as cantilevered structural elements that support the overall system. The failure of a porcelain insulator in this context can lead to disruptions in rail system operation, causing delays in passenger mobility. This study presents a comprehensive investigation into the structural performance of cantilevered porcelain posts used in overhead railway transmission lines. The experimental testing, conducted in a laboratory setting, aimed to evaluate the insulators' structural integrity under various conditions. The outcomes of this study shed light on different failure modes and performance characteristics observed across insulators. This information is crucial for improving the design and maintenance practices related to cantilevered porcelain posts in overhead rail systems.
Efectos de la Interacción Humano-Estructura pasiva en propiedades dinámicas de estructuras
Authors: Ortiz Lizeth Calderón , Castillo Bryan , Thomson Peter
Published: January 2025

This paper investigates the passive effects of human-structure interaction (HSI) on the dynamic properties of civil structures. Experimental campaigns were conducted on a cantilever test structure, first with human subjects standing passively on the structure, and then with inert loads simulating the mass of the occupants. The results show that the presence of passive occupants significantly reduces the natural frequencies and increases the damping coefficients of the coupled human-structure system compared to the empty structure and the structure with imposed masses. This highlights the importance of properly considering the dynamic coupling between people and the structures they occupy, rather than simply treating occupants as additional imposed masses. Anthropometric characteristics of the test subjects, such as weight and height, were found to influence the magnitude of HSI effects, although no direct correlation was observed, indicating that other factors, such as body mass distribution and joint stiffness, also play a role. The pressure insoles data provided more information on how passive occupants interact with the structure in terms of load distribution and dynamic response. These results underscore the need to better understand and model passive HSI to achieve structured designs.

Authors: Saback Vanessa , Gonzalez-Libreros Jaime , Popescu Cosmin , Blanksvärd Thomas , Täljsten Björn , Sas Gabriel , Eliasson Jens
Published: January 2025

Digital twins (DT) are seen as a transformative solution for the Engineering & Construction (E&C) industry’s challenges. However, there is a gap between DT research and operational applications. This paper proposes a framework for a DT, exemplified by a trough bridge case study at Luleå University of Technology (LTU). Traditional bridge management relies on manual, time-consuming methods, leading to reduced accuracy and reliability. The DT platform integrates a 3D model with real-time Structural Health Monitoring (SHM) data, providing a collaborative environment for asset management. The proposed platform can be scalable to other structures; it facilitates data interpretation and decision-making, offering a step towards enhanced asset management practices. By bridging the gap between potential and operational applications of DT technology, this study contributes to the evolution of efficient asset management practices in the E&C industry.

Efectos de la corrosión sobre las pérdidas por fricción y sus consecuencias para el control del tensionamiento en puentes de concreto preesforzado continuos durante obra a partir de un caso de estudio
Authors: Londoño Piedrahita Cristian Camilo , Góez Sara Sánchez
Published: January 2025

Durante la construcción de los puentes de concreto preesforzado, la corrosión de los cables es uno de los problemas que comúnmente generan más diferencias entre los coeficientes de fricción empleados por el diseñador y los encontrados al momento de realizar los tensionamientos. Esto se evidenció durante la construcción de un puente vehicular continuo ubicado en zona urbana del Valle de Aburrá (Antioquia, Colombia), por lo cual las predicciones de las elongaciones realizadas durante la etapa de diseño se alejaban del caso real. Esto muestra la importancia de realizar un seguimiento a la construcción y de emplear las recomendaciones de control de elongaciones y procedimientos de tensionamiento referenciadas en normas como la AASHTO, ACI y Eurocódigo, las cuales serán presentadas. Otras variables importantes son el nivel de detalle de los cálculos y tipo de modelación numérica realizadas en el software de análisis estructural.

Authors: Navarro-Mora Angel
Published: January 2025

The failure of a structure can occur due to various aspects, among these that the design decisions are not consistent with the construction and reality of the structure. This study carried out a forensic analysis of the structural failure that occurred in a 57 m long vehicular suspension bridge. The main objective of this study was to identify the cause of the structural failure that affected the trusses of the suspension bridge. To achieve this objective, a meticulous forensic analysis of the project was carried out. This analysis involved a detailed review of the documentation related to the structure. Additional information necessary for the study of the bridge was obtained, which included a detailed geometric survey of the bridge, testimonies and information about materials. A detailed inspection of the damages was carried out. Subsequently, an analytical study was conducted, using third-order computational analysis to include the effect of large deformations. The results of the study indicate that the designer did not consider the stiffness and strength of the truss in the design of the bridge, which resulted in the bridge’s buckling failure due to a vehicle with an approximate weight of 24 tons. In conclusion, it was determined that the failure was because the decisions in the design process were not consistent with how the bridge was built.

Authors: Sheshnev Aleksandr , Reshetnikov Mikhail , Gerasimov Oleg
Published: January 2025

For many decades, two main watercourses in the town of Volsk (Saratov region) have been serving the transit function of sewage effluents to the Volgograd reservoir. Sampling of bottom sediments was carried out along the length of the Verkhnyaya and Nizhnyaya Malykovka watercourses in order to analyze the specificity of the chemical composition of alluvial formations under technogenic impact conditions. The fraction of technogenic particles (plastics, coal, paint, synthetic fibers, etc.) was 4-20%. In terms of chemical composition, alluvium is represented by silicites with varying degrees of clay content., Bottom sediments are characterized as clay silicites, with the maximum content of heavy metals and organic matter (based on the value of loss on ignition) in the areas where wastewater enters the watercourses. The most typical contamination is with zinc, lead, and barium. The overall level of technogenic pollution of bottom sediments is high and can be named considerable in the upper reaches of the Nizhnyaya Malykovka watercourse only. In order to improve the ecological status of the watercourses, a set of measures is needed, including reconstruction and the creation of new infrastructure facilities of the urban environment.

Study of Relationship between Intense Geomagnetic Storms and Halo CME in Solar Cycle 23 and 24
Authors: Masram Mansu , Dhurwey Gopal Singh
Published: January 2025

The SOHO/LASCO sensor recorded 53 rapid Earth-directed halo coronal mass ejections (CMEs) from January 2009 to September 2015. According to the statistics, solar flares and CMEs during solar cycle 23 were stronger than during solar cycle 24. An X-class flare's halo coronal mass ejection is one of the solar system's most intense events because of its size, velocity, and strong geomagnetic storms. A total of 86 X-class CMEs were evaluated, with 43% rated as very geoeffective, 28% as moderately so, and 29% as less so. The percentage of storms with geoeffective Ness ranged from 71% in 1996 to 29% in 2019. In cycle 23, there were 78% geoeffective storms; in cycle 24, that number dropped to 56%. Due to the lack of information on the speed of the CME that occurred on December 6, 2006, the study focused on 85 halo CMEs associated with X-class flares. The study found that all types of halo CMEs contribute to the disruption of the Earth's magnetic field, and that 42.18 percent of all CMEs with velocity more than 1000 km/s may cause substantial geomagnetic disturbances.

LESSONS FROM THE BHAGAVADGITA FOR MODERN MANAGEMENT PRACTICES
Authors: Rai Shruti
Published: January 2025

India’s intellectual heritage has generated an extensive body of literature on fundamental issues like life, death, spirituality and the universe. When we look back at our legacy and understand it, we found that It’s not just knowledge, but continuing practice of wisdom, insight, and self-discovery. One such source of timeless knowledge is the Bhagavadgita. The Bhagavadgita, the most esteemed scripture of Hindu philosophy, has made significant contributions to the philosophical, religious, and spiritual domains of Hindu thought, earning great respect and acceptance among the global intellectual community—from scientists to spiritual figures. When we refer to Hindu thought, we are talking about the Hindu lifestyle, not the religion itself. Lord Krishna delivered this teaching on the battlefield of Kurukshetra to advise Arjuna about his responsibilities as a warrior to combat for justice. This ongoing counseling, spanning eighteen chapters, covers all management strategies aimed at attaining mental balance and overcoming crisis situations. Whether it is the transformation of human personality, achieved through a genuine comprehension of spirituality, into a vibrant, joyful existence that maintains equanimity in all situations, the ethical aspect of social existence, along with idea of Lokasangraha, focused training for optimal performance- all these crucial points of management have discussed in the Bhagavadgita. This is an effort to contemplate some lessons from the Bhagavad Gita and their relevance to contemporary management practices in the current global landscape, and how they might combine with Western approaches for an improved world.

Published: January 2025

From ancient times to the present day, gold has served as a powerful symbol of wealth, power, and prestige, adorning the crowns of kings and the sacred relics of religious institutions. But beyond its material value, gold has also come to represent deeper concepts such as purity, enlightenment, and the divine. It gives the security against any financial crisis, because of its easy liquidity, and is also used by women for adorning themselves. For Indians, jewellery holds immense significance both in a cultural and religious sense. They also form an integral part of various ceremonies and festivities, such as weddings, cultural festivals, and religious rituals. Similarly, jewellery play a vital role in Indian culture and traditions. Besides, it is often passed down through generations, representing family heritage and traditions. This paper analyses consumer level of awareness and satisfaction towards buying behaviour of gold jewellery. The data required for the study collected form women through well-structured interview schedule and analysed the data with the help of statistical tools such as garrett ranking, weighted average score, etc. so as to draw a meaningful conclusions.

This study has examined Uzbekistan’s environmental assessment framework, focusing on the challenges impeding Strategic Environmental Assessment implementation, as well as how international practices and pilot initiatives can guide the establishment of a robust and sus-tainable domestic SEA system. Through the analysis of legal documents, reports and pilot action outputs, the study has identified deficiencies in decision making and inconsistent mainstreaming of ecological matters into strategic planning. Thus, the major challenges include limited SEA awareness, insufficient baseline data, and weak legal and regulatory setting. Pilot projects, such as the Charvak Free Tourist Zone SEA, had revealed tangible concerns, including difficulties in engaging local stakeholders, data gaps, and unclear inter-agency roles. While these do represent significant obstacles, they also offer valuable lessons learnt for forging a comprehensive SEA scheme. Although the absence of a strong legal basis remains a critical limitation, there exist opportunities to enhance coordination, oversight, and stakeholder inclusivity. Uzbekistan can build on international SEA trends associated with public engagement and climate risk evaluation, while also learning from regional and cross-border actions. Collaborations across Central Asia, particularly in managing shared water and biodiversity resources, render additional opportunities for harmonizing environmental governance. The key priorities include the adoption of SEA legislation, capacity building through training and awareness programs, and the establishment of national networking and information exchange mechanisms. These steps are vital for fostering sustaina-ble development, preserving natural resources, and building public trust in ecological governance. The study findings furnish actionable insights for policymakers and practitioners in Uzbekistan and other nations facing similar environmental assessment challenges.

O comportamento de consumo está em constante mudança, influenciado pela globalização, migração para o online e eventos inesperados. Nesse cenário, é vital repensar o ponto de venda, tornando-o mais humanizado e estratégico. A proximidade com os clientes, o uso eficaz de visual merchandising e consultoria de cores são cruciais para decisões de compras assertivas. Com base na importância do ponto de venda, o presente artigo buscou compreender como as estratégias de visual merchandising e a consultoria de cores podem afetar a decisão de compra do varejista. Por meio de um estudo de caso em uma loja atacadista de moda feminina, utilizando pesquisas quantitativa e qualitativa, chegou-se à conclusão de que a consultoria de cores atrelada ao visual merchandising impacta não apenas a decisão de compra, mas também auxilia a equipe comercial a realizar uma venda com maior valor agregado.

A cor é considerada o elemento mais potente na comunicação de moda. Ela representa um componente primordial para a construção da identidade de uma marca. A Chanel, fundada por Gabrielle Chanel, apresenta cinco cores que são consideradas como clássicas da marca: preto, branco, bege, dourado e vermelho. O presente estudo tem como objetivo quantificar a incidência das cinco cores clássicas da marca em seu desfile ready-to-wear de outono-inverno 2024/25 e comparar com as demais cores presentes no desfile. O método utilizado foi a pesquisa exploratória na modalidade estudo de caso. O tratamento e análise dos dados ocorreu por meio de uma abordagem quantitativa. Os resultados indicam que as cores clássicas representaram 55% dos looks 73 looks apresentados, com destaque para o preto, o branco e o bege. Ainda, identificou-se a presença de outras cores, consideradas não clássicas, com destaque para o rosa e o laranja. Concluiu-se que as cores clássicas, especialmente o preto, permanecem centrais na identidade da marca, preservando sua herança, ainda que adicione elementos atuais para se manter relevante a seus consumidores.

La adaptación de un espacio para la educación de los sordomudos en el siglo XIX mexicano. Experiencias y avatares en la construcción de una cultura escolar

La Escuela Nacional de Sordomudos (ENS) fue fundada oficialmente en la ciudad de México tras la restauración de la República en 1867, y fue la primera experiencia educativa en su género que contó con recursos federales para el logro de sus objetivos de instrucción; pero sus raíces se encuentran en el Segundo Imperio, específicamente en la Escuela Municipal de Sordomudos fundada en 1866. Esta institución puede ser concebida como pionera en lo que actualmente se conoce como educación especial. Este artículo forma parte de una investigación más amplia que estudió la construcción de la cultura escolar de la Escuela Nacional de Sordomudos en sus primeros años de existencia; no obstante, el objetivo de este trabajo únicamente se centra en dar a conocer cómo se cristalizó uno de los tres elementos que el historiador francés Dominique Julia (1995) consideró indispensables para la configuración de una cultura escolar institucional: el espacio propio, esto es, el espacio físico que permitiría la organización y consolidación del proyecto educativo. Para ello, se recuperaron las ideas de Dorothy Tanck y Antonio Viñao para el análisis de las fuentes primarias encontradas sobre el proceso de adaptación del edificio escolar y los materiales de apoyo necesarios para la educación de estudiantes que vivían con sordomudez.

Embora a doença da artéria coronária seja a principal causa de infarto em homens e mulheres, existem diferenças pronunciadas relacionadas a sexo e gênero. A placa aterosclerótica na mulher é menos volumosa, os eventos podem ocorrer por erosão da placa com embolização distal, a aterosclerose é difusa e associa-se a disfunção micro-vascular e endotelial. Acomete mulheres uma década mais tarde do que os homens, a dor pode ser torácica (precordial/retroesternal), mas também dor na mandíbula ou no pescoço. O termo doença isquêmica cardíaca (DIC), hoje mais recomendado, engloba o amplo espectro da doença coronária, desde a clássica doença aterosclerótica epicárdica, a disfunção microvascular, disfunção endotelial, as anormalidades vasomotoras, dissecção espontânea das artérias coronárias, as cardiomiopatias induzidas por estresse e outras condições associadas ao desbalanço entre oferta e consumo de oxigênio. A fisiopatologia, apresentação clínica, diagnóstico, exames complementares, abordagem terapêutica e os desfechos da DIC obstrutiva e não obstrutiva devem seguir um roteiro hierarquizado, conforme diretrizes das Sociedades Europeia e Americana de Cardiologia. Particularmente, o MINOCA é um diagnóstico em construção, realizado por etapas, envolvendo um conjunto de informações sequenciais, principalmente relacionadas aos métodos de imagem invasivos e não invasivos. Assim, em pacientes com angina, a tomografia pode ser utilizada para excluir doença coronária obstrutiva; o ecocardiograma pode realizar avaliações iniciais para definir o grau de comprometimento e determinar a função sistólica e diastólica. A tomografia por emissão de pósitrons (PET) e a ressonância podem confirmar a presença de isquemia ou definir a etiologia da lesão miocárdica e, nos pacientes nos quais estes exames sejam indicativos destas alterações, o paciente pode ser encaminhado para exames invasivos

The aim. The synthesis of nanoparticles through green methods is a biologically safe, cost-effective and environmentally friendly approach. This study focuses on the green synthesis of copper nanoparticles using aqueous stem extract of Tinospora cordifolia. Additionally, this research explores the formulation of an acetyl amine-modified xanthan gum-based gel incorporating curcumin and a solution of Cu++ nanoparticles, and investigates its wound healing activity.

Materials and methods. The shade-dried stem of Tinospora cordifolia was extracted with distilled water, which serves as a bio-reducing agent for the synthesis of Cu++ nanoparticles. Copper sulphate was added to the extract at room temperature using a magnetic stirrer. The visual color change during the addition indicates the formation of nanoparticles, which was further confirmed by UV spectroscopy and particle size analysis. The  modified xanthan gum-based gel formulation was  prepared using curcumin and a solution of Cu++ nanoparticles, and its wound healing activity was evaluated using the excision method, along with antimicrobial activity assessed by the cup and plate method.

Results and discussion. UV absorption was observed at 261 nm, and the particle size was measured at 188 nm, confirming the formation of nanoparticles. The gel containing curcumin and  Cu++ nanoparticles was prepared using modified xanthan gum. The nanocomposite exhibited significant antimicrobial activity against gram-positive bacteria compared to gram-negative bacteria. The group treated with the modified xanthan gum-based curcumin and nano copper composite demonstrated significant wound closure by day 16±2.

Conclusion. The  synthesis of  Cu++ nanoparticles using Tinospora cordifolia and the formulation of a gel with modified xanthan gum and curcumin as a drug were successfully achieved. The  gel formulation demonstrated significant antibacterial and wound healing activities, attributed to synergistic effect of Tinospora cordifolia, curcumin, and Cu++ nanoparticles.
