Medical drone system for automated external defibrillator shock delivery for cardiac arrest patients
Authors: Atheena Milagi Pandian S. , Rashika Murugan , Mohammed Sahil S.
Published: February 2025

Fibrillation, a disorder characterized by an irregular and frequently abnormally fast heart rhythm, is one of the leading causes of heart attacks. There is solid evidence that the survival rate of sudden cardiac arrest patients who are treated with Cardiopulmonary Resuscitation (CPR) plus an Automated External Defibrillator (AED) is much higher. Despite the recommendation that automated external defibrillators (AEDs) be provided in the workplace, along with a proper management system and employee training on how to use the device, less than 70% of non-residential locations have one installed. The situation is significantly worse in residential settings, where less than 30% have an AED fitted. This paper focuses on the development of a medical drone management system that can supply. In the event of a heart attack, the patient or accompanying person can call a medical drone by sending coordinates to the drone station and a notification to medical staff. The drone station administrator can respond by sending the drone, which automatically lands at the patient's location. An app that can be installed on the patient's or accompanying person's mobile phone and tablet has been developed.

Published: February 2025

Over the years, increased industrialization and population have been identified as key factors in the need for energy. Higher pollution levels and rising fuel prices coincide with the growing demand for renewable energy. Biodiesel, a renewable, biodegradable, and sustainable alternative to fossil fuels, has gained significant attention. Biodiesel offers a promising alternative to traditional biofuel, with benefits including renewability, sustainability, emitting fewer air pollutants, low sulphur content, energy security, being easier to treat, stronger lubricity, and lower levels of exhaust emissions than petroleum diesel fuel. However, challenges remain, including high production costs and land use concerns. Accordingly, in this study, apart from the scope and need of biodiesel, an attempt has been made to address the number of process parameters that influence the production process of biodiesel, the sources of biodiesel production, and the obstacles and possibilities that will shape its future trajectory. This study adds to a greater knowledge of biodiesel as a renewable energy source by delivering crucial insights and suggestions. It also gives advice for future research, policy development, and industry actions targeted at supporting its sustainable expansion and acceptance.
Exploring need for enhancing play activity time in school settings for holistic development of learners
Authors: Neha Madan
Published: February 2025

For optimal child development, play time has been recognized by the United Nations High Commission for Human Rights as a right of every child. But access to free time has been reduced due to the impact of one or other factors such as current lifestyle, changes in family pattern, increased academic pressure, and unsafe spaces for children until and unless they are under close supervision of adults or caregivers and place of physical aspects of play taken by the digital world. This study explores the significance of play for the holistic development of learners through an observation schedule and focused group discussion as a tool in real school settings. Sample comprised of students from classes VI-VIII and teachers of elementary classes from selected schools, which comprised approximately 10 schools, and locale for the study was private schools from North East Delhi, which were part of the internship program of B.Ed. trainees of one of the GGSIP University-affiliated B.Ed. colleges in East Delhi. From analysis and interpretations of findings, it was revealed that in more than 50% of schools, playgrounds were missing and hardly one game period in a week was given. Mostly students were indulged in their self-created games as provision for outdoor games was less. Further findings through observation lead to the conclusion that play activities contribute to the holistic development of learners. On FGD with teachers, it was interpreted that play activities helped them in dealing with socio-psychological problems of learners, but there is a lack of human and non-human resources for support of play activities for students in the school environment, both in terms of physical and social resources. The findings of this study have also given a few strategies so that play activities can be given due importance for the holistic development of learners in school settings.

Two-headed eagle in contemporary Russian poetry
Authors:   Russian State University for the Humanities, Markov Alexander V.
Published: February 2025

The image of the double-headed eagle, the imperial sign in old Russian poetry, in the nonconformist poetry of the Soviet period has come to signify spiritual resistance and the superimposition of different epochs. The geographical and heraldic interpretation of the image was replaced by a particular historical imagination, in which the semantic content of the epochs is not fully preserved after the revolutionary upheavals, and only a heroic personality is sufficient to unite the meanings. A close reading of the poems of Russian nonconformists and post-Soviet poems proves how the cult of the thing established by the poets of Acmeism is peculiarly refracted in these works. The psychological realness of Acmeism allowed these poets to deploy contradictory modes of nostalgia and historical judgment, with a common vector of moral evaluation of the recent past.

An Analysis of the Republic of China’s Policy on the Approval of the Provisional Government of the Republic of Korea
Authors:   The Association for Korean Modern & Contemporary History, SUN Yan-hong
Published: February 2025

In May 1940, Kim Gu asked for approval of the Provisional Government of the Republic of Korea(the Provisional Government), but about a year later, after the Korean Volunteers Army moved north, the Chinese government changed its passive attitude and began to actively discuss the approval of the Provisional Government. And around the end of November, an approval policy was established on the premise of the unification of the Korean revolutionary forces.
After the outbreak of the Pacific War, the Chinese government had to take into account the positions of the combatant nations and neighboring countries when dealing with the issue of the Provisional Government. After U.S. President Roosevelt's radio address, the Chinese government decided to formally approve the Provisional Government in the face of public opinion that the U.S. would soon approve it. However, in consideration of the international environment, Jang Ga-seok accepted the opinion of the United States and delayed the approval of the Provisional Government.
After the Cairo Declaration, Koreans’ distrust and dissatisfaction with the Chinese government increased. In this situation, the Chinese government virtually approved the provisional government to maintain friendly relations with the Provisional Government and establish a pro-China regime in Korea after the war.
China and the U.S. have cited unification between independence movement forces as the reason for reserving the approval of the Provisional Government. However, it is true that the issue of integration of independence movement forces is a critical task for the Korean independence movement camp to overcome. The Provisional Government continued its efforts to establish an integrated government to increase anti-Japanese capabilities and obtain the official approval.

Published: February 2025

Abstract
The study has the objectives to conduct desk research to identify available AI‐based solutions for detecting false information and to benchmark the identified solutions against a set of features to take into account for an implementation at the European Food Safety Authority (EFSA). The desk research identified 58 potential commercial platform candidates, 39 other but less applicable candidates and 8 related solutions from the intelligence sector. It further reviewed 5 EU tools, 19 EU funded projects, 17 academic projects and 3 other resources. Based on desk research, an initial benchmarking was performed using refined criteria, resulting in the identification of 10 top candidates for deeper analysis. These candidates were assessed through in‐depth research, including direct provider interactions. Questionnaires were sent to lower‐scoring platforms to further validate the desk research. A final benchmarking analysis, accompanied by a SWOT analysis, was produced for the top candidates. A framework for evaluation, incorporating various levels of actions, actors, tools, and knowledge, was developed and linked to a maturity model to assess the platforms’ suitability at different maturity levels. The study identifies solutions that are suitable for EFSA's current and future needs and could provide insights for other agencies and organizations with similar objectives on misinformation monitoring at scale.

DANDA NATA OF ODISHA: A CRITICAL ANALYSIS OF ITS CULTURAL AND RITUALISTIC DIMENSIONS WITH SPECIAL REFERENCE TO BOUDH
Authors: Tripathy Dibya Ranjan , Mallik Santosh Kumar
Published: February 2025

Danda Nata is a vibrant folk tradition celebrated in rural and tribal communities of Odisha, with Boudh district standing out for its unique variations. Held annually during Chaitra (March–April), the festival spans thirteen or twenty-one days and culminates on Maha Vishuba Sankranti. The celebration is marked by rhythmic drumming, energetic dance, dramatic acts, and comedic performances, blending spiritual rituals with theatrical expressions. Central to the festival are the devotees, known as Danduas or Bhoktas, who undertake vows of austerity and devotion, guided by the Pata Dandua or Pata Bhokta. The event unfolds in four phases: Dhuli Danda, Pani Danda, Agni Danda, and Suanga Danda. Each phase involves distinct rituals, physical endurance, and purification through sand, water, and fire. The final phase, Nrutya Danda, features dance, music, and satire. Boudh’s Danda Nata is distinct for incorporating Bandana, a devotional recitation, Dalapuja, a special puja performed before Meru, and Sola Suanga Danda Nata, which includes sixteen forms of dramatic and satirical performances. These elements add depth to the festival, blending humor, folklore, and religious themes. The worship of Lord Shiva and Goddess Kali ties Danda Nata to both Hindu and indigenous traditions. The performance, accompanied by instruments like the dhol, mahuri, flute, and mardal, remains a dynamic cultural experience. In Boudh, Danda Nata continues to evolve, preserving its spiritual and artistic heritage, making it a unique and living expression of Odisha’s folk traditions.
REIMAGINING THE CANON: ANALYZING ADAPTATIONS OF SHAKESPEARE’S PLAYS AND JANE AUSTEN’S NOVELS IN CONTEMPORARY FILM AND MEDIA
Authors: Gupta Roopa
Published: February 2025

The adaptation of literary classics into film and television serves as a dynamic bridge connecting traditional literature with contemporary media, offering new avenues for audiences to engage with time-honored narratives. This paper examines the adaptation process through the lens of William Shakespeare’s plays and Jane Austen’s novels, focusing on the intricate balance between fidelity to the original texts and the creative liberties taken by filmmakers. Drawing on adaptation theories by Linda Hutcheon and Robert Stam, the study explores how adaptations serve not merely as reproductions but as re-interpretations that reflect evolving social, cultural, and artistic contexts.Through detailed case studies—including Baz Luhrmann’s Romeo + Juliet (1996), Akira Kurosawa’s Throne of Blood (1957), Ang Lee’s Sense and Sensibility (1995), and Amy Heckerling’s Clueless (1995)—this paper investigates how filmmakers preserve the thematic core of the original works while employing cinematic techniques to enhance or transform their meanings. The analysis delves into aspects such as cultural transposition, modernization, and audience reception, demonstrating that adaptations often engage in a dialogic relationship with their source material.Key themes such as the tension between tradition and innovation, the role of cultural context, and the impact of modern interpretations are discussed to illustrate how adaptations not only keep classic literature alive but also enrich it with contemporary relevance. This continual reimagining ensures that canonical works remain vibrant, accessible, and meaningful in an ever-evolving cultural landscape. Ultimately, the study underscores the significance of adaptations in preserving and transforming literary heritage, fostering a deeper and more dynamic engagement with classic texts across generations.

The purpose of this study was to use the Markov chain to predict future
honey exports to importing destinations, and analyze honey exports from
India to various major import markets. Secondary data, the yearly export
of honey from India to other countries were collected from 2013 to 2023.
Received: 16 Nov 2024
Revised: 26 Nov 2024
Accepted: 16 Dec 2024
The results showed that the USA, UAE, and Qatar were stable
destinations for Indian honey. At the same time, other importing countries,
like Morocco, were unstable (had low retention probabilities) in their export
share to these markets. The most unstable importing countries were Saudi
Arabia, Libya, and Bangladesh. The predicted export shares of honey to
major importing countries revealed that the export share of Indian honey is
expected to be highest in the USA and UAE over the next four years.

Este estudo apresenta uma análise preliminar da tenacidade à fratura de materiais por meio de simulações numéricas e ensaios convencionais, conforme a norma ASTM E1820. Utilizando o método de elementos finitos e a curva de resistência J-R (Integral J), busca-se avaliar a resistência à propagação de trincas em corpos de prova fabricados em aço AISI 4340. Os objetivos incluem o desenvolvimento de uma metodologia de simulação numérica e a comparação dos resultados obtidos com aqueles decorrentes de ensaios experimentais. A metodologia proposta se mostrou viável para determinar a tenacidade à fratura, entretanto melhorias devem ser introduzidas para melhorar a exatidão.

A cavitação é um importante fenômeno na lubrificação hidrodinâmica que afeta consideravelmente o desempenho dos mancais. Neste contexto, o presente trabalho tem como objetivo investigar o efeito da cavitação no desempenho de um mancal hidrodinâmico radial cilíndrico utilizando o software de CFD OpenFOAM®. Os resultados obtidos demonstraram que devido ao efeito da cavitação, as pressões na zona divergente do mancal não podem ser inferiores à pressão de saturação do vapor de óleo, resultando em uma distribuição de pressão assimétrica e, consequentemente, em uma redução da capacidade de carga do mancal.

La educación ambiental requiere estrategias innovadoras para su efectiva enseñanza. Esta investigación tuvo como objetivo implementar el aula abierta vivencial como estrategia didáctica en la enseñanza de la educación ambiental. El estudio se fundamentó en una investigación cuantitativa bajo la modalidad de proyecto factible con diseño de campo, desarrollado en cuatro fases: diagnóstico, viabilidad, ejecución y evaluación. Se trabajó con una población de cuarenta docentes, seleccionando una muestra del 30%. La recolección de datos se realizó mediante una encuesta utilizando un cuestionario con escala de Likert de tres alternativas (Siempre, Algunas Veces, Nunca), validado por expertos y con confiabilidad determinada por el coeficiente Alpha de Cronbach. Los resultados revelaron que el 75% de los docentes considera que el aula abierta vivencial contribuye “algunas veces” al proceso de enseñanza-aprendizaje, mientras que el 25% indicó que “siempre” es efectiva. Se concluye que el aula abierta vivencial constituye una estrategia viable y efectiva para la enseñanza de la educación ambiental en contextos de educación a distancia, permitiendo mantener la continuidad educativa mientras se fomenta la conciencia ambiental.

The cold rolling effect on the microstructure and mechanical properties of recycled AA6111 alloy with Zr or/and Ni were investigated. All alloys were produced by the stir-casting method. homogenization heat treatment (500 ºC for 6 hours) was performed on AA6111 alloy only. The alloys were solutionized (at 540 ºC for 30 minute) and artificially aged (at 180 ºC for 10 hours). The optical micrograph, scanning-electron microscope (SEM) and X-ray Diffraction (XRD) studies for all samples. The microstructure analysis displayed different fine intermetallic phases distributed in large amounts in alloys containing Zr or/and nickel compared to AA6111 alloy. The combined alloying elements' addition effect with the cold rolling effect and artificial aging led to great improvements in the mechanical properties, where the hardness and tensile properties of all alloys increased. The AA6111+0.41wt%Ni alloy showed the highest hardness value, as it increased to 161 HV after artificial aging, while the AA6111+0.54wt%Zr alloy showed the highest YS and UTS, which increased to 252 MPa and 342 MPa, respectively.

The work done in this research is dedicated to compute the critical buckling load of combined columns. This is performed using theoretical and experimental analyses. The combined column is made of two materials, namely copper and aluminum alloys. The theoretical approach involves numerical analysis using ANSYS and analytical analysis using the equivalent stiffness method. The study determines the critical buckling load by considering many parameters. These parameters include lengths of copper and aluminum in the combined columns, cross-sectional geometries (square, circle, and hexagon), and boundary conditions. The experimental work is carried out using a Strut Bucking Apparatus on a combined column with circular cross-sections and different end supports. The findings show that the critical buckling loads achieved from numerical and analytical analysis are in good agreement with those obtained from experimental analysis. It is found that the critical buckling load increases with increasing the length of copper in the combined column and with more restrictive end supports. There is a good match of critical buckling load between those achieved from the equivalent stiffness method and ANSYS model for any considered cross-sectional geometries (square, circle, and hexagon) and two types of support (fixed-fixed and fixed-pinned). The results reveal that the combined columns with square cross-sections have higher critical buckling loads than those with circular or hexagonal cross-sections. The highest percentage errors of critical buckling load between the experimental method and theoretical methods (equivalent stiffness method and ANSYS models) are (-13.120, -12.768, and -12.453) % and (-13.083, -18.039, and -19.052) % for pinned-pinned, fixed-pinned, and fixed-fixed columns respectively.

Authors: Alaasam Yamama , Alalikhan Ahmed
Published: February 2025

The present study involves strengthening process applied upon brick walls to increase their ultimate load carrying capacity or improving their ductility behavior by using different types of strengthening materials. These materials include either traditional well-known materials or newly proposed materials. The traditional materials include steel wire mesh (SWM) and carbon fiber-reinforced polymer sheet (CFRPS) while the proposed materials include recycled damaged tire strips (DTS). The purpose of using such abundant and polluted material is to satisfy, respectively, the economic considerations and clean environment in the field of enhancing the structural behavior of brick walls. Eight brick walls models were constructed with dimensions of (1200×1200×240) mm, respectively represent width, height and thickness of each model to be tested by 45° compressive loading. Results exhibited that, the SWM increases the ultimate load carrying capacity for the strengthened models to 51.85% compared to the non-strengthened model when placed on one side of the model. Also, the use of CFRPS placed on one side and on both sides of the strengthened models increases the ultimate load capacity respectively to 18.2% and 385% compared to the non-strengthened model. The DTS material has no ability to increase the ultimate load capacity (-18.2 %) but it successfully converts the brittle behavior of the brick walls to a ductile one. It is recommended to use DTS to increase the ductility for brick walls that are likely be damaged or collapsed to avoid the sudden failure.
