Published: December 2024

Abstract. The January 2022 disintegration of multi-year landfast sea ice in the Larsen B embayment, Antarctic Peninsula, was closely followed by a significant acceleration of ice flow and ice-front retreat of numerous outlet glaciers. Crane Glacier was a notable example of this, with 6 km of its floating ice shelf lost to calving in the first month following the disintegration and a 3.4 % increase in terminus flow speeds over the same time period. In this study we quantify for the first time the buttressing stresses that were transmitted to Crane by the ice melange at the glacier outlet using the ice-flow model Úa. We constrained our model with high-resolution surface elevation profiles of the glacier and ambient melange and reconstructed the observed flow velocities by optimising the rheology rate factor throughout our model domain. This allowed us to quantify the stress regime across both the glacier and ice melange. Results showed that resistive backstresses were imparted to Crane by the ice melange with a mean buttressing ratio of ΘN=0.68 calculated at the glacier terminus (ΘN=1 implies no buttressing). In addition, diagnostic modelling showed an expected 19.2 kPa mean increase in extensional stress at the ice front following the disintegration of the ice melange. This perturbation in stress likely triggered the observed rapid calving over the near-terminus region, leading to the periodic loss of sections of Crane's buttressing ice shelf and thus further acceleration of ice flow in the subsequent months.
Joule heating: Halloween Storm on 29-31 October 2003
Authors: Abraham Sherin Ann , Antony S. , Kumar C.P. Anil
Published: December 2024

Estimation and prediction of Joule heating is essential for studying the satellite drag, which causes a malfunctioning
or complete loss of the satellite. This paper focuses on the production and enhancement of Joule heating and its
dependence on the AE (Auroral electrojet) index during a Carrington-like event that occurred from 29th October to
31st October 2003. Simulated Joule heat from the global Magneto-Hydro-Dynamic model- Space Weather Modelling
Framework (SWMF) is compared with Joule heating values obtained AE based empirical models. This analysis shows
a similar spatial and temporal variation in both the Joule heating values and a similar magnitude with a moderate
correlation. No other solar wind or plasma parameters show significant influence on Joule heating values during this
extreme geomagnetic storm.

Published: December 2024

The midlatitude positive bays (MPB) represent a mark of the development of substorms at auroral latitudes.To have a knowledge of their parameters could serve as a tool to obtain more information about the magnetospheric substorms onset and progress. In the purpose to enable the study of the various phenomena related to the substorm disturbances and their propagation to mid-latitudes, an original catalog of the variations of the magnetic field at midlatitudes at the Bulgarian station Panagyurishte (PAG) was created for the period 2007 - 2022. The MPB parameters are part of this catalog. To estimate the MPB parameters, a special methodology was worked out. The beginning and end of the MPB’s were determined, based on smoothing by moving average and by inspection of the consecutive minima before and after the MPB maximum, calculated by the first derivative of the X component of the magnetic field variations. Criteria to choose the minima of the beginning and end of the MPB have been discussed and set. For each specified case, a graphic of the positive bay with some parameters marked in it, and a file with the determined parameters and some flags, giving information about the concrete positive bay, have been created. These results can be accessed in the Catalog of the magnetic variations at the Panagyurishte station, located on the website
of the Space Research and Technology Institute, BAS, Bulgaria (http://space.bas.bg/Catalog_MPB/).

Here we analyzed four very intense substorms with the AL-index reached ~ -1500 nT and recorded in the main phases of the strong magnetic storms on 27 February and on 23-24 March 2023. The global dynamics of the considered very intense substorms have been studied basing on the AMPERE satellite data provided the maps of the ionospheric and field aligned currents (FAC) distributions in the planetary scale. These maps are constructed by analyzing the magnetometer measurements from the Iridium constellation of 66 simultaneous low-altitude (780 km) communication satellites. The common features of the considered intense substorms have been established. It was found that in the substorm intensity maximum, there was the strong morning-side magnetic vortex with clockwise rotation, indicating an intensification of the downward FACs, probably associated with the enhanced magnetosphere-ionosphere convection. The strongest westward electrojet was observed in the early morning sector and it was accompanied by the significant increasing of the post-noon eastward electrojet as it was found by [Despirak et al., 2021, 2022] to be typical for the supersubstorms. The large-scale eastward electrojet with intensity comparable to the
westward electrojet, occurred at lower latitudes in huge longitudinal area - from the afternoon to the late evening. The latitude area between westward and eastward electrojets can be referred to the conventional Harang region.
Reference responses of regional electron content to strong geomagnetic events
Authors: Ratovsky K.G. , Klimenko M.V. , Vesnin A.M. , Beluchenko K.V.
Published: December 2024

The paper presents an analysis of reference responses of regional electron content to strong geomagnetic events identified by the AE-index. As an ionospheric characteristic, we used the regional electron content (REC), which is the average total electron content (TEC) for five latitude zones in the corrected geomagnetic coordinate system: the mid-latitude zones in both hemispheres, the high-latitude zones in both hemispheres, and the equatorial zone. The relative (percentage) deviation of observed values from the 27-day running average REC was used to calculate disturbances of REC (ΔREC). The reference response was calculated by averaging ΔREC using the superimposed epoch method with key moments corresponding to the AE maximum for the winter, spring, summer and autumn storms. The paper discusses storm-time behavior, seasonal dependence and interhemispheric asymmetry of the REC responses to strong geomagnetic events.

Проанализированы случаи с экстремальными значениями геомагнитно-индуцированных токов (ГИТ) в линиях электропередач (ЛЭП) на Кольском полуострове за квазисолнечный цикл 2012-2022 года. Использованы данные подстанции Выходной (VKH). Из 93 экстремальных событий на станции VKH с ГИТ>20 А 46 (49.5%) были вызваны CME магнитными бурями, 41 (44.1%) происходило во время CIR магнитных бурь и 6 (6.4%) происходило без магнитных бурь. Экстремальные всплески ГИТ наблюдались как в предполуночном, так и послеполуночном секторах MLT. Не наблюдается строгой связи между величиной ГИТ и скоростью солнечного ветра, параметром V*Bs, параметром Акасофу ε. Также не наблюдается строгой зависимости между величиной ГИТ и индексами геомагнитной активности IE, AE, величиной ГИТ и dB/dt.
Geomagnetic characteristics of the magnetospheric ring current and the plasma parameter β of the solar wind
Authors: Makarov G.A.
Published: December 2024

По среднегодовым значениям рассмотрены связи геомагнитных индексов Dst, SYM-H и ASY-H с плазменным параметром β солнечного ветра в период с 1981 по 2015 гг. Получено, что с ростом солнечной активности уменьшается параметр β, что означает повышение магнитного давления солнечного ветра и, соответственно, увеличение геомагнитной активности вследствие роста уровня турбулентности солнечного ветра. Установлено, что индексы зависят от параметра β: их абсолютные величины уменьшаются с ростом β независимо от знака северо-южной компоненты межпланетного магнитного поля. Уменьшение индексов с ростом β происходит, вероятно, из-за перехода магнитосферы в спокойное состояние вследствие возрастающего преобладания в солнечном ветре теплового давления над магнитным давлением и уменьшения уровня турбулентности солнечного ветра.

В настоящей работе представлены результаты лабораторного эксперимента по разлету плазменного облака
во внешнее магнитное поле, впервые демонстрирующего подавление характерных Холловских эффектов
присутствием фоновой плазмы. Показано, что увеличение концентрации фоновой плазмы приводит к
снижению величины Холловских магнитных полей и соответствующих токов, что, в свою очередь, изменяет
характер протекания коллапса диамагнитной каверны. При подавлении Холловских эффектов динамика
каверны протекает более плавным образом и задерживается по времени. Полученные данные не только
обнаруживают влияние фоновой плазмы, но и подчеркивают взаимосвязь между Холловскими эффектами и
аномально быстрой динамикой магнитного поля на фазе коллапса диамагнитной каверны.

Authors: Raykova L.
Published: December 2024

The study presents an investigation of the impact of the solar activity on the temperature regime of the cave atmosphere in the zone of constant temperatures in the Uhlovitsa karst cave, located in the central part of the Rhodope Mountains. The course of the ground-level atmospheric temperature in Smolyan, a city located closest to the cave entrance, has also been studied. For the work, databases for the temperatures in the cave and in Smolyan, and solar activity indices from public databases for the number of sunspots (Sn), the total solar irradiance (TSI), and the solar radio emission F10.7) have been used for the period 1968 – 2022. The analysis of the temperature regimes in the specific underground environment and the area adjacent to the cave shows significant correlations between the solar activity and the temperature regime in Uhlovitsa cave. The study is an attempt to establish links and a physical understanding of the complex interactions between solar activity and the ground-level atmosphere.

В работе рассмотрены экспериментальные данные, характеризующие красные дуги в области субавроральных широт. Установлено, что они имеют другую физическую природу по сравнению с хорошо известными «классическими» красными дугами, которые наблюдаются на средних широтах и вызываются ионно-циклотронной неустойчивостью энергичных ионов кислорода и водорода кольцевого тока.
«Классические» красные дуги наблюдаются на восстановительной фазе больших магнитных бурь.
Субавроральные красные дуги возникают при суббуревой активности и могут наблюдаться на любой фазе магнитной бури. Эти дуги развиваются в полосе поляризационного джета. В них, в отличие от «классических» красных дуг существует сильное электрическое поле, направленное на север в среднем 20-40 мВ/м, которое разогревает среду и порождает быстрый продольный и поперечный дрейф плазмы со скоростями до 1.5 - 2.0 км/с, согласно измерениям спутников DMSP на высоте 850 км.
По параллактическим сканерным измерениям высота максимума свечения субавроральной красной дуги составляет 180-200 км. Интерферометрические измерения показывают, что в полосе красной дуги температура нейтральной атмосферы [Tn] повышена до 1200-1450 К относительно среднего уровня, определенного по невозмущенным дням месяца [около 1000 К].
Investigation of the earthquake (Michoacan-Colima) in Mexica (19.09.2022) by using GNSS stations and INSAR observations
Authors: Pırtı Atınç , Yücel Mehmet Ali
Published: December 2024

The North American Plate is subducted under the Cocos and Rivera plates, while the Pacific Plate divides from the North American Plate near the spreading centre of the Baja California Gulf, placing the Mexican Republic in a seismically active area of the world. The earthquake of a magnitude of Mw 7.6–7.7 occurred 37 km southeast of the town of Aquila (near the municipality of Coalcoman) at a depth of 15.1 km on 19.09.2022 at 18:05:06 UTC (13:05:06 local time (LT)). This study focuses on the use of GNSS (Global Navigation Satellite System) data to investigate the Mexican earthquake, and the results (using static-kinematic methods) are presented in this paper. The TNCC and COL2 IGS stations, which are situated to the north and northwest of the fault, recorded the largest displacements after GNSS data processing. At five points, 9–25 cm horizontal motions were obtained in the southwest, northwest, and west directions. The quantity of horizontal motions, however, was smaller in the south of the fault stations UCOE (approximately 9–10 cm) and PENA (about 9 cm). A comparison between the GNSS and InSAR (Interferometric Synthetic Aperture Radar) results from the COMET-LiCSAR analysis showed that the GNSS and InSAR solution mirrors the pattern of earthquakes. The GNSS and InSAR data were aligned by standardizing to a common spatial and temporal grid, with corrections for atmospheric delays and noise. The mirroring of patterns was evaluated by using correlation analysis, displacement magnitude comparison, and assessment of spatial gradients. Error tolerances were considered to validate the alignment and highlight any discrepancies.
Von Téchne|τέχνη zu Epistéme|ὲπιστήμη und Phrónesis|φςόυηις
Authors: Barta Heinz
Published: December 2024

Die Anfänge wissenschaftlichen Denkens lagen im Handwerksbereich und wurden mit Téchne umschrieben, was neben Handwerk, auch Kunst(fertigkeit) und Geschicklichkeit sowie geistige Gewandtheit bedeutete. Der Begriff Téchne blieb für zahlreiche Disziplinen – Medizin und Rechtsdenken ebenso wie die Rhetorik – lange bestimmend. Man gab sich mit praktischem Wissen zufrieden, weshalb mit dem Aufkommen von Mathematik und Geometrie und dann dem naturwissenschaftlichen Denken von Aristoteles und Theophrast ein neuer Begriff gesucht und mit Epistéme gefunden wurde. Diese ›strengen‹ Wissenschaftsdiszplinen fragten nicht nur danach, ob etwas praktisch ›möglich‹ war, sondern auch nach den Gründen, warum das der Fall war. Man strebte nach bleibendem und logisch-begründbarem, ja möglichst ewigem Wissen. […] Als Auslöser für den dritten Entwicklungsschritt – der mit Phrónesis umschrieben wurde – dienten eine Reihe weiterer Disziplinen zu denen neben Politik, Rhetorik, Philosophie und Ethik, auch Téchne nomothetiké oder dikastiké zählte; Bezeichnungen, die zunächst für den gesamten Rechtsbereich standen und etwa ›Jurisprudenz‹ bedeuteten. – Für alle diese Disziplinen paßte weder der Begriff Téchne, noch Epistéme. Es brauchte etwas vermittelnd Neues, was mit dem Begriff Phrónesis gefunden wurde. Auch diese neuen Bereiche wollten wissenschaftlich-methodisch und logisch korrekt vorgehen und ihr Wissen begründen. – Phrónesis brachte – über Logik und Methode hinaus – abwägende ›Klugheit‹ und damit eine gewisse Beweglichkeit in das wissenschaftliche Denken. Parallel dazu schildere ich den Weg antiken griechischen Rechtsdenkens zur weltweit ersten ›Jurisprudenz‹ und den kulturellen Einfluß, den das bereits entwickelte und flexible griechische (Rechts)Denken auf das noch unentwickelte römische Recht genommen hat; dies ermöglichte den Römern ihr Recht von einem starren ›pontifikalen Rigorismus‹ (U. Manthe) zu einer wissenschaftlichen Jurisprudenz zu entwickeln. – Unvermeidbar war deshalb die Auseinandersetzung mit Meinungen, welche die Entwicklung des griechischen Rechtsdenkens zur Jurisprudenz leugnen.

La Carpetania durante la Segunda Edad del Hierro. Análisis socioespacial del interfluvio Tajo-Jarama-Tajuña
Authors: Sánchez de Oro Pablo
Published: December 2024

El presente artículo presenta una nueva aproximación valle medio del Tajo durante la Segunda Edad del Hierro a través del estudio de caso del interfluvio Tajo-Jarama-Tajuña. Para este territorio durante esta cronología, las fuentes clásicas refieren la existencia de una entidad étnica homogénea: los carpetanos. Combinando las Tecnologías de la Información Geográfica (en adelante: TIG) —particularmente análisis de movilidad y visibilidad— y trabajos previos, es posible profundizar en el conocimiento que se posee sobre estas poblaciones, su identidad y su organización. Todas las técnicas empleadas muestran la existencia de comunidades pequeñas y autónomas interconectadas entre sí. De tal forma, es posible establecer la existencia de una pluralidad de entidades étnicas, así como la importancia del medio —especialmente de los cursos de agua— como verdadero organizador del territorio y posible generador de identidad. Por último, planteamos la posible correlación con el modelo de Interacción Política entre Pares publicado por Colin Renfrew en 1986.

En este trabajo se presenta una propuesta de reconstrucción del entramado urbano del poblado vettón de El Raso (Candeleda, Ávila) a partir de un análisis combinado del legado de las excavaciones realizadas en el sitio hasta los años 90 y de los nuevos trabajos de indagación no invasiva. Si los primeros aportan un conocimiento detallado de la configuración de los espacios domésticos y la secuencia de ocupación del sitio, los segundos nos permiten avanzar en la definición de la organización espacial interna de la totalidad del asentamiento. Valorado de manera conjunta, todo este conocimiento permite definir la configuración del hábitat conforme a un modelo urbanístico que destaca por su densidad y regularidad. Dicho esquema nos permite aproximarnos a la lógica social del espacio utilizada por esta comunidad, ponerla en el contexto histórico de las últimas etapas del mundo vettón y valorar parámetros esenciales como la estimación demográfica del poblado. Estos resultados son comparados con las tramas urbanas detectadas en otros poblados del mismo ámbito cultural, confrontando los diferentes modelos que actualmente baraja la investigación sobre esta temática en el ámbito del occidente de la Meseta peninsular.
Innovación y adaptación de las televisiones públicas europeas: de la emisión lineal a las plataformas OTT
Authors: Etura Hernández Dunia , Redondo García Marta
Published: December 2024

Este estudio analiza la transformación de las radiotelevisiones públicas europeas en su transición desde la televisión lineal hacia plataformas de transmisión OTT (Over The Top o de transmisión libre) y evalúa su capacidad de adaptación y los desafíos que enfrentan en la era digital. La investigación, que se centra en 13 radiotelevisiones públicas seleccionadas por su antigüedad y pertenencia a la Unión Europea de Radiodifusión (UER), se enfoca en aspectos como la accesibilidad, la distribución de contenido y la usabilidad de sus plataformas BVOD (Broadcaster Video on Demand). A pesar de haber lanzado sus propias plataformas de streaming para competir con servicios comerciales, estas radiotelevisiones afrontan retos significativos en cuanto a la personalización de la experiencia de usuario y la producción de contenido exclusivo, lo cual limita su competitividad. La mayoría sigue utilizando un modelo de catch-up: ofrece contenido previamente emitido, en lugar de desarrollar contenido original y exclusivo. Otro desafío importante es captar la atención de las audiencias jóvenes, lo que requiere no solo la adaptación del contenido, sino también una mayor interactividad y experiencias digitales mejoradas. Además, el estudio destaca la suboptimización en las aplicaciones móviles de estas plataformas, un aspecto clave considerando la importancia de la experiencia de usuario en dispositivos móviles, especialmente para el público joven. Por último, aunque muchas de estas radiotelevisiones poseen un archivo audiovisual valioso, no siempre lo explotan adecuadamente, por lo que pierde la oportunidad de fortalecer la conexión cultural y aprovechar la nostalgia en sus audiencias.
El Intermedio. Un enfoque innovador sobre la sátira de actualidad.
Authors: Nevado Ignacio , Fernández-Ramírez Laura
Published: December 2024

El infoshow es el macrogénero de mayor crecimiento a nivel global durante las últimas décadas. Esto se debe, en gran medida, a los procesos de desregulación de los mercados televisivos, que han fomentado que los contenidos se adapten cada vez más a los gustos y demandas de la audiencia. En España, el auge del infoshow comenzó en la década de los 2000, en un contexto de crisis económica y desafección política que propició un mayor interés del público general por temas económicos, sociales y políticos, todos ellos muy propicios a la crítica y la espectacularización. En este contexto, la sátira de actualidad se consolidó como un género destacado en la televisión española. Esta investigación se centra en El Intermedio, producido por Globomedia para La Sexta. Este programa formaba parte de los primeros contenidos con los que la cadena inició sus emisiones oficiales, en el año 2006, y sigue presente en su prime time dieciocho años después. Se trata, sin duda, del programa más longevo y, también, uno de los de mayor éxito de su parrilla. Aunque sigue la tradición de formatos previos, El Intermedio ofrece un enfoque innovador alejándose del ámbito puramente humorístico para ofrecer un acercamiento alternativo a las noticias de actualidad. Mediante el análisis de contenido de sus diez primeras temporadas se analiza el perfil de sus presentadores y colaboradores y su estructura de contenidos. Los resultados muestran un enfoque innovador en el tratamiento de las noticias y en el equilibrio entre la función informativa y el entretenimiento.
El fútbol sin imágenes de fútbol. Innovar en la programación deportiva durante la crisis de los derechos audiovisuales: el caso de El Avispero de Aragón TV
Authors: San Martín Jorge , Bonaut Joseba , Zugasti Ricardo
Published: December 2024

El artículo analiza el programa de Aragón TV El Avispero, considerado un caso relevante de innovación en la programación deportiva en un contexto caracterizado por la crisis de derechos deportivos y la difícil coyuntura económica que se dieron entre 2013 y 2016. Para ello, se emplean tres tipos de fuentes. En primer lugar, las bibliográficas y hemerográficas han servido para contextualizar el objeto de estudio. En segundo lugar, se usan fuentes documentales inéditas: la escaleta de una emisión representativa del programa, que plasma los contenidos, su jerarquía y enfoque, y las memorias anuales internas de la televisión pública aragonesa, que permiten analizar aspectos como, por ejemplo, los resultados de audiencia y su evolución. Por último, la realización de cinco entrevistas en profundidad a los máximos responsables de la cadena televisiva y del programa objeto de estudio constituye la principal fuente de esta investigación. Las conclusiones señalan que la creatividad fue clave a la hora de generar contenidos futbolísticos durante aquel periodo, manteniendo así la apuesta por los deportes, sin contar con imágenes. Una apuesta que se reveló exitosa, como demuestran los datos de audiencia y la continuidad de El Avispero en la parrilla durante varias temporadas. Se produjo así una transformación en la estrategia de programación deportiva de Aragón TV, que comenzó con la posibilidad de ofrecer contenidos premium durante sus primeros años y, por el contrario, tuvo que adaptar sus espacios a una situación de austeridad en las últimas temporadas de la primera década.
Sociologia da Infância e o direito de voz das crianças: reflexões sobre o conceito de polifonia
Authors: Brito Dhemy
Published: December 2024

A retórica de “dar voz às crianças” tem sido destacada na Sociologia da Infância, entretanto pouco se tem avançado em torno da confirmação prática do compromisso com os direitos das crianças. O conceito de polifonia, apresentado neste estudo, propõe um novo paradigma para a promoção de práticas mais harmoniosas, promovendo o diálogo horizontal entre as vozes adultas e infantis, baseado na igualdade, na ética e no respeito mútuo. Distanciando-se dada a noção tradicional de “dar voz”, que implica o controle do adulto sobre “se” e “quando” as vozes infantis são ouvidas, a polifonia sugere uma abordagem colaborativa e co-construtiva. O conceito articula-se em torno de três esferas de orientação: cultura, autonomia e reconfirmação, e questiona se as vozes das crianças estão a ser efetivamente incorporadas nos processos de tomada de decisão que afetam os seus contextos. Uma reflexão sobre estas questões é crucial para situar a polifonia como forma de deslocar o poder dos adultos, promovendo práticas que considerem verdadeiramente as contribuições das crianças. Assim, a polifonia não se limita às crianças ouvintes, mas transforma as suas vozes em agentes de mudança, reconhecendo-as como participantes essenciais na construção de uma sociedade mais democrática com as crianças. Em última análise, o conceito se estabelece como um símbolo de compromisso, baseado em valores de liberdade e cuidado, tanto não que diga respeito à infância, mas também às crianças, proponho um novo modelo de interação que realmente valorize e integra as vozes múltiplas e plurais das crianças.
Las políticas migratorias o la producción de una mano de obra sobreexplotada. Los usos del trabajo migrante en Francia y Canadá
Authors: Verón Daniel
Published: December 2024

¿Cuáles son las condiciones sociales e históricas que hacen posible la sobreexplotación de la fuerza de trabajo de estas mujeres y hombres que cruzan las fronteras para vender sus manos, sus cuerpos? En otras palabras, ¿cómo se constituye históricamente la mano de obra migrante como fuerza de trabajo específica? Para responder a estas preguntas, el artículo examina cómo los sucesivos estatus de subordinación conferidos a los migrantes se convierten en el principal resorte de una mayor explotación laboral dentro de los diferentes segmentos del mercado de trabajo. En una época de capitalismo globalizado y de internacionalización de las cadenas de valor, la mano de obra migrante se despliega, por tanto, al menos de dos maneras distintas: o bien a través del enfrentamiento de los derechos laborales y los sistemas de protección social, o bien a través de la denegación del derecho de residencia y, por tanto, de la plena inclusión en el derecho común. En el primer caso, encontramos el trabajo desplazado en Europa y, más ampliamente, toda la gama de prácticas de gestión laboral denominadas «off-shore» en un marco desterritorializado en el que los derechos nacionales pueden eludirse legalmente. En el segundo caso, es la figura del inmigrante indocumentado la que aparece como emblemática de la exclusión del derecho común como trampolín para la sobreexplotación.
The impact of some agricultural policy indicators on investment in the Iraqi economy Dumooa Sadeq Khudhair
Authors: Jasim Mohammed
Published: December 2024

The study examined some of the factors that influence the investment decision and
recognized the essential elements that are directly related to the investment. Based on
this concept, the elements directly related to agricultural investments, as well as their
purpose or objective and the factors influencing them, were examined. The study
concluded that the analysis of the course of fiscal policy in the Iraqi economy did not
show a clear idea of whether there are antecedent goals for fiscal policy to be achieved
by aligning financial instruments in a specific direction to achieve these goals . which
reflected the methodology of partial fiscal policy decisions in the agricultural economy.
This limited the overall impact of financial policies and procedures. The study
recommended the need to increase interest in agricultural science research and the
development of special technologies in the agricultural sector, especially those
researches and studies that maximize the benefits of investment in agricultural land due
to its scarcity and low productivity, so that the agricultural sector can be play a role in
development, address the problems of agricultural production and achieve food security.

Published: December 2024

This article explores the relationship between CO2 emissions, economic growth, energy consumption, and, other control factors for the eight highest CO2-emitting countries (USA, Russia, Iran, China, Germany, India, Japan, and Canada) in 1995-2023. The m objective of the study is to determine how economic growth (GDP), energy consumption (EC), industrial production (IP), and other macroeconomic factors influence CO2 emissions. Using panel data analysis, this study applies various econometric techniques, including fixed and random effects models, Multicollinearity tests, heteroscedasticity tests, and cross-sectional dependence tests. Independent variables include GDP, Total energy use, Industrial output, Density of the population, and Trade while the dependent variable is CO2 emission. The results suggest that energy consumption positively correlates with CO2 emission, where, for each unit of energy consumption, CO2 emission increases by 0.0024 units. The outcomes also reveal a negative correlation of international trade with CO2 emissions implying that trade inhibits emissions. However, the relationship between GDP and, carbon emissions was formed to be statistically insignificant. Population density and industrial production have mixed effects on emissions, with industrial production showing a positive impact. The study emphasizes the importance of adopting cleaner energy sources, enhancing energy efficiency, and considering trade policies that might reduce emissions. The findings suggest that transitioning from coal and oil to cleaner energy sources, such as natural gas, could be an effective strategy for reducing carbon emissions without significantly hindering economic growth. The study provides valuable insights for policymakers in high-emission countries aiming to balance economic development with environmental sustainability.

Smallholder farmers’ engagement in the school feeding program was aimed at the regular supply of foodstuffs to schools and enhancing learner participation. Learners from marginalized households are affected by food shortages, poor healthcare, and a lack of nutritious meals. The study aimed to assess the influence of smallholder farmer engagement in school feeding program and learner participation. A sample of 275 was employed from a population of 875. Information was gathered using a questionnaire, and interview guide. Quantitative and qualitative information were analyzed using descriptive, and inferential statistics. Simple linear regression models demonstrated the variables' strength and relationship. Pearson's Product Moment Correlation coefficient(r) was computed. The overall F statistics was 2.795. The outcomes were represented in tables, regressions, mean, standard deviations, frequencies, and percentages. The null hypothesis was tested, thus there is no significant association between small-scale farmer engagement and learner participation (P-value 0.006 <0.05) suggesting a statistically significant correlation between small-scale farmer involvement and learner participation. This implies that learners were not provided with adequate meals resulting in school dropouts, absenteeism, and lack of concentration in class.

Published: December 2024

Leadership in the modern school organization is key to forming a school team committed and motivated to fulfill the strategic goals of the institution, for its development and improvement of the organizational culture. The school principal is a leader by virtue of the authority given to him by holding the position, called to make management decisions. He can have "innate" qualities of a leader or acquire and develop them with the help of trainings and qualifications. Regardless of what type of leader the head is, he must build a vision for the development of the organization and motivate employees to follow it, create conditions for shared knowledge and achieve quality education and effective development of the institution with the participation of pedagogical specialists, parents, interested countries etc. For this purpose, the school director should possess certain qualities, which are the subject of research in this article. A survey conducted among teachers and students ranked the leadership qualities of the informal and formal leader in the educational institution. The most significant qualities according to the opinion of the respondents were analyzed and a comparison was made between the opinions of future and current teachers. The conclusions of the comparative analysis show the priority qualities of the formal and informal leader, as a result of which recommendations are given related to the characteristics of the leader, which must be possessed and developed for purposeful and effective performance of the position of director and for the fulfillment of the goals of the organizational strategy of the school.

Diabetes mellitus (DM) is a chronic illness, caused due to
resistance to insulin or poor production. Diagnostic criteria
of Diabetes mellitus (DM) has been devised by World Health
Organization (WHO), American Diabetes Association (ADA),
based on plasma glucose level. Hemoglobin A1c (HbA1c)
level remains the gold standard test for the assessment of
glycemic control, and it reflects the mean glucose values
in the previous 3 months period. HbA1c is expressed as
a percentage, whereas the monitoring and treatment of
diabetes are based on blood glucose levels expressed as
mg/dL. It is appropriate to make it easy for the patient to
understand both random blood sugar (RBS) and estimated
average glucose (eAG) expressed with the same units.
“Estimated average glucose” or eAG derived from HbA1c has
been promoted by the American Diabetes Association (ADA).
American Association of Clinical Chemists concludes that
the correlation (r =0.92) is strong enough to justify reporting
both HbA1c and eAG which indicate the 3 months control of
the average sugar of the patient. This article determines the
statistical correlation between eAG derived from HbA1C with
RBS values both in diabetic and prediabetic subjects.
Methods: The RBS and HbA1c levels of 123 males and 39
females (12 – 70 years) were obtained and the eAG levels were
calculated using Nathan’s regression equation. The samples
were divided into three groups on the basis of HbA1c levels as
group 1: HbA1c greater than or equal to 6.5% (diabetic),group
2: HbA1c 5.7 to 6.4% (prediabetic), and group 3: HbA1c less
than 5.7% (non diabetic).
Results: A total of 162 (123 males and 39 females) were
enrolled for the study. The mean ±SD values of RBS, HbA1c
and eAG of the population were 167.44 ± 88.74 mg/dl, 7.23
±2.14 % and 161.20 ± 61.43 mg/dl respectively. HbA1C values
were significantly correlated with RBS (p <0.001) and eAG (p
<0.001).
Conclusion: The clinical importance of HbA1C,eAG in
diagnosis and management of Diabetes Mellitus (DM) can
be re-emphasized by this study. HbA1C along with eAG may
be added as a test in the management of Diabetes Mellitus
(DM), for the better understanding and maintenance of good
glycemic control. However, eAG and RBS values cannot be
used interchangeably.

The Mechanical Behaviour of Granular Soil Interfaces Using the Discrete Element Method
Authors: Bairoti Mohammad , Pulat Hasan Fırat
Published: December 2024

Understanding the mechanical behaviour of granular materials is essential for many engineering applications. The Discrete Element Method (DEM) makes understanding particle interactions easier and provides vital insights into granular mechanics. Compared to conventional trial-and-error techniques, DEM offers a more accurate representation of bulk material behaviour by considering variables like Poisson's ratio, density, shear modulus, coefficient of restitution, static friction, rolling friction, and material characteristics. Engineers can investigate granular material behaviour at different scales and improve their engineering designs using platforms such as Altair EDEM version 2022.1, which provides a reliable framework for in-depth DEM investigations. Traditional methods like finite element analysis (FEA) and the finite difference method (FDM) cannot comprehensively analyse granular materials due to their oversimplified assumptions and poor representation of particle interactions. DEM overcomes these limitations by providing a more accurate representation of particle-scale interactions, making it a preferred choice for simulating granular materials in complex engineering scenarios.
This study employs the DEM to investigate the macro- and micromechanical shear behaviours of sand particles. For this purpose, a three-dimensional (3D) program (EDEM) was used to model a direct shear test (DST). The results show that the DEM can accurately determine the shear strength parameters of granular soil under various loading conditions. Specifically, it was observed that an increase in shear rate leads to an increase in the internal friction angle, confirming the DEM’s capability to simulate actual DST conditions. These findings align well with literature studies and laboratory test results, demonstrating the method's efficacy in geotechnical soil interface analysis.
