Need for Urgent Reforms in the United Nations Security Council: Pathways to Equitable Representation
Authors: Sangroula Yubaraj
Published: January 2025

The United Nations (UN) has faced growing criticism over time for structural inefficiencies, lack of transparency, and the underrepresentation of diverse voices in critical decision-making processes. This article examines the necessity of reforming the United Nations Security Council (UNSC) with a focus on the controversial veto power wielded by the permanent members (P5). The veto system, has contributed to imbalanced decision-making, undermining the principles of equitable representation, especially for smaller and landlocked nations like Nepal. Analyzing the historical and contemporary practices of the Security Council, the article explores the legal and structural challenges posed by the veto system, its role in perpetuating Western hegemony, and its impact on global peace and security. It proposes actionable reforms, including the professionalization of Council representation, the inclusion of regional players in decision-making, and the decentralization of UN functions.

Published: January 2025

Los estudiantes de ingeniería presentan dificultades para desarrollar habilidades de pensamiento estadístico en los cursos de Probabilidad y Estadística, lo que resulta en altos índices de reprobación, retrasos en el egreso y una baja cultura estadística. Esta problemática, evidente en el aula, surge cuando los estudiantes deben relacionar teoría, procedimientos e interpretación de resultados. La falta de claridad en sus conclusiones afecta su desempeño profesional en el mercado laboral, especialmente en áreas que demandan habilidades estadísticas.
El estudio tiene como objetivo final diseñar un curso de Probabilidad y Estadística que use R Studio como herramienta de apoyo para mejorar el desarrollo del pensamiento estadístico. Este enfoque se basa en los principios de que el trabajo ocurre en sistemas de procesos interconectados, existe variabilidad en todos los procesos y que comprender y reducir esta variabilidad es clave. Incorporar R Studio permite a los estudiantes aprender un lenguaje de programación relevante y adquirir competencias útiles en asignaturas futuras y en su carrera profesional. En esta etapa se presentan los referentes previos al diseño y desarrollo del curso.

The Emergence of Quantum Mechanics from General Relativity Electromagnetism and Charge Quantization
Authors:   JBX Consulting, USA, E Brandenburg John
Published: January 2025

Based on the concept of the Big Bang of the universe being governed by the principles of Minimization of Action and Minimization of rate of Entropy production
in a the Very Early Universe, where the expansion of Spacetime was superluminal, both QM (Quantum Mechanics) and electrodynamics can be seen to be
emergent rather than foundational with both being a consequence of electric charge quantization and electromagnetism in an expanding spacetime. Postulating
the appearance of the “Electrically Entangled” electron charge quanta, which are identified as 5th dimensional vectors in a Kaluza-Klein mathematical framework,
both plus and minus, at very Early times in the Big Bang, plus the existence of electromagnetic fields around those charges, the superluminal expansion of
spacetime prevents electrodynamics and thus EM radiation. This epoch is postulated to end with the formation of the proton in the Hadron Epoch, with its
three quarks forming, with the electron, a Minkowski four vector, and the highly entropic dynamics of the quarks within the proton giving rise to entropy in the
EM field under cosmic isothermal conditions with a temperature defined by Electrodynamics of the quarks interior to the proton rather than electrodynamic
scattering between widely separated subatomic particles. The appearance of a larger unit of action h, thus mirrors the appearance of a larger unit of stable rest
mass, the proton. This correlation is confirmed by the central place of the proton/electron mass ratio in the highly accurate formula derived for α. The emergent
character of the quanta of action is suggested to explain the unfeasibility of quantization of GR (General Relativity) to higher orders and with GR and EM with
charge quantization being the foundation on which QM is built.
A Hybrid Approach to Deep Fake Detection Using Error Level Analysis
Authors: Mrs. Sushma D. S  , Sumanth T.C  , Mehraj  , Likhith.R  , Lohith T. R
Published: January 2025

The rapid advancement of ‘deepfake’ video technology— which uses deep learning artificial intelligence algorithms to create fake videos that look real—has given urgency to the question of how policymakers and technology companies should moderate inauthentic content. We conduct an experiment to measure people’s alertness to and ability to detect a high-quality deepfake among a set of videos. First, we find that in a natural setting with no content warnings, individuals who are exposed to a deepfake video of neutral content are no more likely to detect anything out of the ordinary (32.9%) compared to a control group who viewed only authentic videos (34.1%). Second, we find that when individuals are given a warning that at least one video in a set of five is a deepfake, only 21.6% of respondents correctly identify the deepfake as the only inauthentic video, while the remainder erroneously select at least one genuine video as a deepfake. The process of recognizing and distinguishing between real content and content generated by deep learning algo rhythm’s, often referred to as deepfakes, is known as deepfake detection. In order to counter the rising threat of deepfakes and maintain the integrity of digital media, research is now being done to create more reliable and precise detection techniques. Deep learning models, such as Stable Diffusion, have been able to generate more detailed and less blurry images in recent years. In this paper, we develop a deepfake detection technique to distinguish original and fake images generated by various Diffusion Models. The developed methodology for deepfake detection takes advantage of features from fine-tuned Vision Transformers (ViTs), combined with existing classifiers such as Support Vector Machines (SVM). We demonstrate the proposed methodology’s ability of interpretability-through-prototypes by analysing support vectors of the SVMs

Authors: Zambrano Mas Escólin Dolores , Mamani Quispe Ronald Jhonson
Published: January 2025

El objetivo de esta investigación es evaluar la viabilidad de envases biodegradables fabricados a partir de residuos de arroz (Oryza sativa L.), con el fin de reducir la contaminación por plásticos. La metodología empleada incluyó un diseño experimental cuantitativo en el cual se probaron tres tratamientos, variando las proporciones de almidón, residuos de arroz y glicerina (T1: 20%, 60%, 20%; T2: 30%, 50%, 20%; y T3: 40%, 40%, 20%). Se llevaron a cabo tres repeticiones de cada tratamiento, evaluando la efectividad en la retención de humedad y otras propiedades de los envases producidos en condiciones de laboratorio. Los resultados indican que no hubo diferencias estadísticamente significativas entre los tratamientos (p > 0.05), lo que sugiere que la variación en las proporciones de los ingredientes no afecta considerablemente las propiedades de los envases. Sin embargo, se observó que el tratamiento T3-R2 alcanzó la menor humedad final (8.50%), destacándose en eficiencia de reducción de humedad. Esto sugiere una mayor estabilidad del material, aspecto crucial para la durabilidad de los envases biodegradables.

Authors: Baeza Bernal Cristian
Published: January 2025

A principios del siglo XX al interior de la Región de Antofagasta se experimentaron transformaciones en las relaciones sociales producto de las demandas a nivel global por materias primas, las necesidades alimentarias de la población minera trajeron consigo el uso y continuidad de rutas antiguas que incluso conectaban espacios transfronterizos. Dichos derroteros se hicieron parte de la expansión capitalista mundial contemporánea. A principios del siglo XX, las compañías con capitales extranjeros con sede en Valparaíso utilizan dichas rutas para el comercio y abastecimiento de carne en los enclaves mineros. Estas empresas implementaron modalidades de trabajo que privilegiaron la eficiencia como aspecto central para la distribución de ganado. En ese escenario, la naturaleza del trabajo trajo consigo una disposición y disciplinamiento corporal con los remeseros, quienes estaban encargados específicamente del traslado del ganado bovino por una antigua ruta que conectaba los ayllus de San Pedro de Atacama y la actual ciudad de Calama.

Authors: Ferreira de Oliveira Maria Helena , Rolim de Sousa Reudismam , Martins Nascimento Gonçalves Samara
Published: January 2025

A Unified Modeling Language (UML) é uma tecnologia amplamente adotada para a modelagem de diferentes aspectos dos sistemas de software, sendo importante para guiar as equipes de desenvolvimento ao longo do ciclo de desenvolvimento do produto. As equipes responsáveis pelo produção de sistemas costumam contar com diversas funções, a exemplo de gerentes de projetos, analistas de sistemas, designers, desenvolvedores e outros. Para que essas equipes trabalhem em sintonia, é essencial se ter uma compreensão dos artefatos produzidos e alguns deles podem estar representados por abstrações em diagramas da UML, tornando importante a compreensão de modelos nessa tecnologia pelas partes envolvidas no projeto. Buscando identificar a realidade da aplicação da UML nas empresas, duas questões principais são estabelecidas QP1: como é o uso da UML em empresas de desenvolvimento de software? e, QP2: o que os desenvolvedores pensam sobre o uso da UML por empresas de desenvolvimento de software?. Para responder a essas perguntas, foi realizado um Survey com profissionais que atuam em empresas de desenvolvimento de software. Os resultados apontam que, apesar de a maioria dos profissionais das empresas conhecerem a UML, essa tecnologia ainda está alheia a alguns dos membros das equipes; isso, alinhado à ausência de treinamento em UML por empresas de software, pode se tornar um risco para o projeto.

DESCARTES VE HUME DÜŞÜNCESİNDE KENDİLİK PROBLEMİ
Authors: DURAK Nejdet , DEMİRBİLEK Şulenur
Published: January 2025

Zihin felsefesinin tartışmalı konuları içerisinde sayılabilecek olan kendilik problemi, tarihsel süreç içerisinde okunduğunda töz fikrinin kabulü veya reddi ile doğrudan ilişkili bir konu olarak görünmektedir. Descartes ve David Hume tarihsel süreç içerisinde felsefi düşüncede kırılma noktalarında yer almış iki önemli filozof olarak kendilik problemine farklı yönlerden yaklaşmışlardır. Descartes probleme değişmeyen sabit bir töz arayışıyla yönelmiş ve «cogito» (düşünüyorum) ile sorunun kendi bakış açısıyla çözümünü ortaya koymak istemiştir. Hume ise Descartes’in aksine değişimin sürekliliği içerisinde değişmeyen hiçbir unsurun olmadığını bu nedenle de sabit bir töz, değişmeyen bir kendilikten söz edilemeyeceğini düşünmektedir. Ona göre kesin bilgisine ulaştığımız düşündüğümüz her şey, algılar demeti sayesinde zihnimizde bir bütünlük oluştuğu yanılgısının bir sonucudur. Bu çalışmada Descartes ve Hume’un bizim ifademizle kendilik problemine ilişkin görüşleri ele alınacak ve sonuç kısmında iki görüş arasındaki temel farklar tespit edilecektir.

Evaluating the effectiveness of negotiated planning tools: the case of the Lombardy Region
Authors: Dell’Ovo Marta , Rossitti Marco , Torrieri Francesca , Datola Giulia , Casprini Danny , Oppio Alessandra
Published: January 2025

Regional Law 19/2019 introduced new tools for Negotiated Planning (NP) in Lombardy, aimed at facilitating collaboration between public and private entities. This law introduces various instruments for coordinating public and private entities, such as the Framework Agreement for Territorial Development (Accordo Quadro di Sviluppo Territoriale - AQST), the Program Agreement (Accordo di Programma - AdP), the Simplified Local Agreement (Accordo Locale Semplificato - ALS) and the Agreement for Economic, Social, and Territorial Revitalization (Accordo di Rilancio Economico, Sociale e Territoriale - AREST). However, the assessment of regional interest and performance monitoring of NP proposals remain problematic due to the lack of transparent and replicable indicators. This research paper presents a multidimensional evaluation model, which introduces innovative criteria and indicators to evaluate NP proposals. With the support of multicriteria analysis as a reference evaluation methodology, the model relies on binary indicators to assess the programmatic, planning, territorial, environmental, social, economic-financial, employment and procedural coherence of the proposals. The application of the model to real case studies also makes it possible to test its effectiveness and improve the monitoring of NP instruments. The proposed model thus aims at improving the management and effectiveness of the NP instruments, offering a robust and replicable method for evaluation and monitoring.

Utilizing Geographic Information Systems to Identify Optimal Locations for Establishing Solar Power Plants in the Sebha Region
Authors: Najem Embarka , Alhadar Faraj
Published: January 2025

This study aims to determine the most suitable location for establishing solar power stations in the Sebha region using Geographic Information Systems (GIS). It focuses on integrating geographic and climatic data and applying specific criteria to evaluate the spatial suitability for these stations. The study aims to leverage the region's natural potential by utilizing solar radiation and guiding decision-makers towards optimal sites that offer economic and environmental efficiency. The study used a descriptive-analytical approach and applied several criteria in the analysis, such as solar radiation, slope degree, proximity to transportation and energy networks, and distance from urban areas. The Multi-Criteria Evaluation (MCE) method was also applied within the GIS environment to assess suitable areas. The results showed that climatic factors, such as solar radiation, temperature, and wind, play a crucial role in determining site suitability for solar power stations. The study utilized a Digital Elevation Model (DEM) of the region to produce maps using Spatial Analyst tools within the Arc Map 10.8 package, along with land use maps to create a spatial suitability map. The spatial suitability results for establishing a solar power station indicated that highly suitable areas constitute about 60% of the total studied area, while moderately suitable areas represent around 22%, and areas with low suitability cover approximately 18% of the total area. These findings support efforts to diversify energy sources and establish a scientifically-based database that promotes renewable energy use and sustainable development in the region.

According to the experimental results, the water-cooled concentrating PV system, the concentric PV system, and the solar panel had final plate temperatures of 56.2, 64.7, and 38.4°C, respectively. Furthermore, the panel receives an average of 47.73 watts, or about 56.15% of the panel's power, without the need of the inverter. When using an inverter (mirror), the panel produces an average power of 50.31 watts, accounting for 59.18% of its total power. The average power given to the panel by a water-cooled CPV system is 54.31 watts, or 63.89% of the panel's output. By using the mirror as a reflector and a water-cooled concentrating PV system, the system may create an extra 7.45% and 20.72% of electricity, respectively. In addition, using reflectors and water cooling with the PV panel increased power efficiency from 8.61% to 9.14%.

O câncer gástrico é uma neoplasia maligna que se inicia com sintomas inespecíficos, dificultando seu diagnóstico precoce e aumentando a sua mortalidade, sendo a quarta causa de morte por câncer no Brasil. A gastrectomia é o manejo terapêutico com maior eficácia e o único capaz de curar o paciente para esta doença. O objetivo deste artigo foi analisar os efeitos das diferentes técnicas de gastrectomia durante a cirurgia e no pós operatório do paciente. Foi realizada uma revisão da literatura através das bases de dados médicas PubMed e BVS, utilizando os descritores “cancer gastric”, “gastrectomy” e “treatment” e o operador booleano “AND”. Um total de 25 artigos científicos foram incluídos após a aplicação de critérios de inclusão e exclusão. Por meio dos estudos analisados, foi observado que apesar de cada técnica da gastrectomia dispor de benefícios e malefícios, todas são seguras e eficazes para curar a doença. Elas possuem resultados oncológicos, qualidade de vida e taxa de complicações operatórias e sobrevida semelhantes quando comparadas entre si. Portanto, é necessário apenas analisar se a técnica mais indicada para o caso do paciente é a convencional, laparoscópica ou robótica.

Published: January 2025

Les valeurs mobilisées en conception peuvent porter sur les formes de participation à la conception et sur l’objet même de la conception. Ce chapitre identifie et développe trois enjeux majeurs liés à la prise en compte des valeurs dans le processus de conception : faire émerger et identifier les valeurs; co-construire le sens des valeurs ; et gérer les conflits de valeur. Les différents modes de résolution des conflits de valeurs sont illustrés dans le cas de l’habitat participatif. Une discussion esquisse des pistes de réflexion pour une meilleure prise en compte des valeurs en conception.

Abstract. The eruptions of the Tajogaite volcano on the western flank of the Cumbre Vieja ridge on the island of La Palma between September and December 2021 released large amounts of ash and SO2. Transport and dispersion of the volcanic emissions were monitored by ground-based stations and satellite instruments alike. In particular, the spectrometric fluorescence and Raman lidar for atmospheric moisture sensing (RAMSES) at the Lindenberg Meteorological Observatory measured the plume of the strongest Tajogaite eruption of 22–23 September 2021 over northeastern Germany 4 d later. This study provides an analysis of SO2 vertical column density (VCD) and layer height (LH) measurements of the volcanic plume obtained with Sentinel-5 Precursor/TROPOspheric Monitoring Instrument (TROPOMI), which are compared to the observations at several stations across the Canary Islands. Furthermore, a new modeling approach based on TROPOMI SO2 VCD measurements and the Hybrid Single-Particle Lagrangian Integrated Trajectory Model (HYSPLIT) was developed, which confirmed the link between Tajogaite eruptions and Lindenberg measurements. Modeled mean emission height at the volcanic vent is in excellent agreement with co-located TROPOMI SO2 LH and local lidar ash-height measurements. Finally, a comprehensive discussion of the RAMSES measurements is presented. A new retrieval approach has been developed to estimate the microphysical properties of the volcanic aerosol. For the first time, an optical particle model is utilized that assumes an irregular, non-spheroidal shape of the aerosol particles. According to the analysis, the volcanic aerosol consisted solely of fine-mode inorganic, solid, and irregularly shaped particles – the presence of large aerosol particles or wildfire aerosols could be excluded. The particles likely had an isometric to slightly plate-like shape with an effective half of the particle maximum dimension around 0.1 µm and a refractive index of about 1.51. Moreover, mass column values between 70 and 110 mg m−2, mean mass concentrations of 45–70 µg m−3, and mean mass conversion factors between 0.21 and 0.33 g m−2 at 355 nm were retrieved. Possibly RAMSES observed, at least in part, volcanic secondary sulfate aerosol, which was produced by gas-phase homogeneous reactions during the transport of the air masses from La Palma to Lindenberg.

Abstract. Regional PM2.5 transport is an important cause of atmospheric environment change. However, the variations in regional PM2.5 transport on a synoptic scale with meteorological drivers have been incomprehensively understood. Therefore, this study is targeted at the quasi-weekly oscillation (QWO) of regional PM2.5 transport over central and eastern China (CEC) with the influence of synoptic-scale disturbance of the East Asian winter monsoon (EAWM) circulation. By constructing the data of daily PM2.5 transport flux in CEC in the winters of 2015–2019, we utilize the extended empirical orthogonal function (EEOF) decomposition and other statistical methods to extract the moving spatial distribution of regional PM2.5 transport over CEC, recognizing the QWO in regional PM2.5 transport with the spatial–temporal variations over CEC. The source–receptor relationship in regional transport of PM2.5 is identified with the 2 d lag effect of the North China Plain, as the upwind source region, on the PM2.5 pollution change in the Twain-Hu Basin, as the downwind receptor region in central China. The QWO of regional PM2.5 transport over CEC is regulated by the synoptic-scale disturbance of the EAWM circulation with the periodic activities of the Siberian high. These findings provide new insights into the understanding of regional PM2.5 transport with the source–receptor relationship and the meteorological mechanism in atmospheric environment change.
