Authors: Y. Petseva  , K. Mladenova  , J. Doumanov  , S. Petrova
Published: January 2025

Snake venoms are complex heterogeneous mixtures containing different bioactive molecules with multivalent nature. Most of these components are proteins displaying enzymatic or non-enzymatic biological and pharmacological activities and toxicological potential. Their functional activities on various tissues and organs lead to the manifestation of diverse effects such as neurotoxicity, myotoxicity, cytotoxicity, inflammation, influence on hemostasis, apoptosis, necrosis and other, causing simultaneous damage to various physiological systems. At the same time, the unique molecular features of snake venom compounds make them valuable scientific tools for understanding different physiological processes, and allows them to fulfil their great potential in medicine and pharmacology as therapeutic agents and diagnostic tools. Many snake venom toxins have been found to exert analgesic, antiplatelet, hypotensive, antitumor, anti/pro-inflammatory or other potencies, as some of them have already been used as a base for design of commercially available pharmaceuticals.
CARCASS CHARACTERISTICS, NUTRITIONAL VALUE AND SAFETY OF CROCODILE MEAT
Authors: R. Fasulkova  , M. Strateva  , D. Stratev
Published: January 2025

In the last few years, the European Union has reported increased imports of fresh, chilled or frozen meat, including crocodile meat. Industry has been developing and has invested largely in its efforts to improve quality and increase meat yield by innovating its methods of farming, feeding and carcass processing. The reason, on the one hand, is the fact that crocodile meat is perceived not only as “exotic” and “adventure”, but also as dietary and healthy, with high nutritional value, due to its low fat and sodium content and high protein percentage. The approximate composition of Crocodylus niloticus meat shows protein levels of 15.7-22.08%. In the other species Crocodylus pororsus, Caiman yacare, Alligator mississippiensis and Caiman latirostrisis the average amount of protein is 20-21%, making it a food rich in protein, such as chicken, pork, lamb and beef. Crocodile meat contains high levels of monounsaturated fatty acids (MUFA) – between 33.2% and 51.3% and saturated fatty acids (SFA) – between 26.0% and 41.4%. It is quite delicate, with low cohesiveness, high elasticity and tenderness. It is juicy, without the presence of connective tissue with an intense taste and an almost imperceptible aroma. Iron, magnesium and sodium levels in crocodile meat are lower than those in beef and chicken. The low sodium content is another indication of the health benefits of crocodile meat. The paper dwells on the qualitative characteristics of crocodile meat, focusing on its safety as a product for human consumption and presents data about by-products obtained from crocodiles used in ancient and modern medicine, beneficially affecting human health.
MODULATING AND STIMULATING THE IMMUNE SYSTEM THERAPY IN PEOPLE WITH HIV/AIDS - ADVANTAGES AND POSSIBILITIES - REVIEW OF THE LITERATURE WITH SHARING OF OWN EXPERIENCE

Published: January 2025

The immune system in people living with HIV can range from normal to severely dysfunctional, depending on the timing of ART initiation and adherence. The use of immunostimulating and immunomodulating drugs in HIV/AIDS still hides many unknowns. Various types of immunotherapy, including monoclonal antibodies, interferon, cytokines, immunomodulatory drugs, allogeneic hematopoietic stem cell transplantation, and most importantly ART adherence, have shown efficacy in HIV-associated opportunistic infections and neoplasms. The beneficial effect of immunotherapy in autoimmune, inflammatory and oncological diseases in the course of HIV/AIDS is based on reducing the pathological damage of the immune system and modifying the disease processes by interfering with cellular metabolism and nucleic acid synthesis, as well as the production of antagonist molecules of inflammation. While most known immunomodulators reduce pathological disorders of the immune system, newer "checkpoint inhibitors" have been developed to improve immune surveillance in oncological diseases. Some cancer immunotherapies can affect HIV latency and HIV-specific immunity. Knowing the benefits of immunotherapy in people with HIV/AIDS and opportunistic diseases will improve their clinical care, providing a unique opportunity to gain insight into the mechanisms of HIV eradication. We present two cases of AIDS and Pneumocystis jirovecii pneumonia where we administered immunomodulators concurrently with ART and specific etiologic therapy. One patient died.

Authors: B. Blagova  , S. Mitov  , D. Krastev
Published: January 2025

Background: Head injuries are not so uncommon in emergency medicine. Generally, separate areas of the face and skull are affected. Some situations are challenging, especially when the traumatic foreign bodies are still inside tissues. So, every single clinical case should be thoroughly described to serve as a basis for an operative method and protocol creation for a therapeutic approach in future injuries of this type. In the current communication, we intend to report our experience with an incident of a stab injury in maxillofacial surgery.
Methods: A middle-aged male patient with a stab wound in the face underwent surgical removal of the knife under intubation anesthesia in emergency conditions.
Results: The postoperative period was uneventful. The patient was discharged on the fifth day with satisfactory early postoperative results.
Conclusions: Together with the anatomical specifics of the region, the surgery for knife removal is more complicated and riskier than usual. On the other hand, exactly rich blood supply determines quick and uneventful wound healing.
TYPE 2 DIABETES MELLITUS, RECURRENT DEPRESSIVE DISORDER AND ANXIETY DISORDERS
Authors: Y. Petkov
Published: January 2025

There are gender differences in the comorbidity of major depressive disorder, anxiety disorders, and type 2 diabetes, according to several studies. New research reveals that insulin and insulin signalling are connected to neurotransmission of several significant neurotransmitters, as well as neuro-modulation and neuroprotection, refuting the notion that the brain is insulin insensitive. Brain insulin resistance, which may result from peripheral insulin resistance, has been linked to depressive symptoms through changes in neuronal functions. Antidepressant effects may be enhanced by IGF-I's direct stimulation of neurogenesis. Other widely accepted pathophysiological mechanisms that have been proposed by several authors include GR, MR, HPA, adipokine hormones such as ghrelin and the orexigenic hormone, as well as pro-inflammatory factors and adiponectin, leptin, and resistin.

In this work the basic research of the main characteristics of burning of diesel fuel is executed. Normal speed, turbulent speed, burning zone extent concern them. Parameters are received at various coefficients of excess of air and various temperatures. Pilot studies on installation are conducted. Installation contains the Bunsen burner and the direct-flow camera of rectangular section with two stabilizers of a flame. As a result of the conducted researches new data on the normal and turbulent speed of a flame of diesel fuel are obtained. It is established that combustion of diesel fuel is carried out according to the superficial scheme. Dependences for determination of normal and turbulent speed of distribution of a flame are revealed.
Assessment of position of forward border of the front of a flame and back border of a flame depending on composition of mix is executed. Parameters were defined for different speeds of the running stream. Dependences of length of a zone of burning on composition of mix are also received at various reference temperature and speeds of the running stream. The dependence allowing to consider influence of pressure and temperature on the normal speed of burning is given. The received results of process of burning of diesel fuel are analysed and generalized. For assessment of the mechanism of burning the criterion representing the relation of volume of a flame in which there are chemical transformations to torch volume is used.
The equations by means of which it is possible to calculate the burning zone extent, speed of distribution of a flame, burning time are defined empirical. The obtained data are necessary for calculation of processes of combustion of diesel fuel in the GTD combustion chamber. Calculations are carried out on the basis of the theory of turbulent burning.

Published: January 2025

This paper describes a computational study of the aeroacoustics interaction that occurs between propellers and wings. A numerical approach is proposed, in the frequency domain, for predicting far-field propeller noise, which requires the aerodynamic sources to be integrated over the actual blade surface, rather than over the propeller disk. This numerical approach has been validated by experimental results and result of acoustic-vortex method. In this paper has presented several configurations of propeller and wing (tractor propeller, pusher propeller, propeller over the wing) and concluded the aerodynamic interaction and advantage of such configurations. Cases of single propeller and four different propeller-wing configurations have been simulated. The result shows for light aircraft in cruise speed the propeller-wing interaction effect aerodynamic performance of propeller, but aeroacoustics interaction may not have great effects on sound level and noise radiation directivity. Instead of this, the unsteady loading on propeller blade may change the noise radiation directivity and amplitude more than either the wing radiation noise which caused by the propeller installation effect or isolated propeller operated in the uniform flow.
Динамічні аспекти опріснення морської води шляхом виморожування
Authors: Рамазанов Р.І.
Published: January 2025

Дана концепція виникла після проведеного у роботі огляду і порівняльного аналізу переваг та недоліків значної кількості методів опріснення, які застосовуються у наш час. Зроблено висновок про те, що багато з них споживають значні електричні потужності, які необхідні під час здійснення стандартної дистиляції, тобто чергування кипіння та конденсації морської води. Такі процеси мають порівняно низький ККД та характеризуються в цілому негативним впливом на навколишнє середовище. Удосконалення методів опріснення виморожуванням необхідно з низки причин. Сама ідея чергування затвердіння і плавлення води не потребує, в принципі, обов’язкової кристалізації морської води у структуру льоду перед його наступними фазовими перетвореннями у більш слабкий (weak brine) у порівнянні з вихідним розсолом (brine). Можливою являється стратегія економії електроенергії на першому із вказаних етапів шляхом отримання аморфних форм, які складаються з великої кількості умовних фрагментів – градин. Вони структурно і внутрішньо менш пов’язані зсередини та між собою. Тому їх плавлення досягається при менших затратах енергії, хоча і потребує повторення декількох, а не одного, як прийнято, циклічних перетворень. Більш ефективне розділення продукту такого циклу бажано здійснювати при невеликих відхиленнях від атмосферних умов з метою мінімізації впливу на навколишнє середовище. У роботі встановлено, що саме перераховані характеристики можливої оптимізації опріснення методом виморожування спостерігаються у природі без будь-якої участі людини. Розчин великої кількості солей поводиться, в цілому, при циклічній зміні температури доби, сезонної температури, зниження і підвищення зовнішнього та гідростатичного тиску, як від’ємний бінарний азеотроп. Він характеризується максимумом температури кипіння при дуже малих тисках, а також самоорганізацією процесу безперервного очищення на кожній стадії опріснення

Published: January 2025

Introdução: Dentre as condições que demandam Cuidados Paliativos (CP), as doenças cardiovasculares têm recebido destaque mais recentemente. A dificuldade de reconhecer a terminalidade em cardiopatias tem sido indicada como fator que compromete a qualidade do cuidado de fim de vida destes. Objetivo: Objetiva-se avaliar a percepção de cardiologistas (C) sobre a expectativa de óbito e a necessidade de CP para pacientes portadores de cardiopatia avançada e/ou terminal. Método: Estudo observacional prospectivo no qual foram coletados em um dia dados demográficos e clínicos dos pacientes internados em um centro de cardiologia. Os C que assistiam estes pacientes responderam um questionário com  2 “perguntas surpresa” relativas à expectativa de óbito em um ano e na internação atual. A partir do padrão de respostas ao questionário, os pacientes foram classificados em perfis: doença em evolução/avançada não terminal (I/II), terminalidade (III) e fase final de vida (IV). Além disso, foram questionados quanto à necessidade de CP para cada paciente.Um Paliativista (P) respondeu às mesmas “perguntas surpresa” com base em dados dos prontuários. Resultado: Foram avaliados 242 pct (90% dos internados), dos quais 34 evoluíram a óbito na internação. Os C  e o P classificaram 35,5% e 4,1%  dos pacientes como perfil IV, com acerto na previsão de óbito na internação de 32,6% e 70%, respectivamente. C reconheceu a necessidade de CP para 93 pacientes, mas solicitou avaliação do P a apenas 13 (14%). Conclusão: Após a observação do desfecho, observa-se que P acerta mais a previsão de óbitos dos pacientes. Apesar de C reconhecer necessidade de CP, solicita interconsultas da especialidade para minoria dos pacientes, reforçando a necessidade de maior articulação entre C e P.
Numerical study on the damage evolution of UHPC lining in LRC gas storage
Authors: Ci X. , Yang J. P. , Chang A. G.
Published: January 2025

Ultra-high performance concrete (UHPC) lined rock caverns (LRCs) are regarded as potential underground hydrogen storage facilities in the future. This paper establishes a finite element numerical model of UHPC LRCs to study the damage evolution process of UHPC lining under different influence factors, for example rock elastic modulus, lining thickness, and steel plate thickness. Four characteristic internal pressures (P1–P4) are determined based on the damage evolution results. P1: tensile strength is firstly reached on the inner surface of the lining. P2: tensile strength is reached on the total section in the thickness direction of the lining. P3: the maximum plastic tensile strain changes from the inner surface to the outer surface of the lining due to the damage to the surrounding rock. P4: localisation of plastic strain through the lining thickness direction, that is formation of macro-cracks. The increase in lining thickness can significantly delay the damage evolution process of UHPC and increase the maximum gas storage pressure, while the effect of steel plate thickness is negligible under the same increased percentage.
Comparative experimental investigation of direct tension and Brazilian splitting behaviors of thermally-damaged crystalline rocks: unique negative poisson's ratio effect
Authors: Huang Xiaolin , Zhang Xiaohui , Qi Shengwen
Published: January 2025

Typically, a rock's direct tensile strength (DTS) is lower than its Brazilian splitting tensile strength (BTS). This disparity becomes more pronounced when subjected to thermal damage. However, a comparative and in-depth analysis of the mechanisms underlying these disparities remains lacking. We experimentally investigated the direct tensile and Brazilian splitting behaviors of crystalline rocks exposed to different heat-treated temperatures. The tensile curve of dog-bone shaped samples showed declines in peak stress, slope, and failure displacement with increasing heat-treated temperature. The disc-shaped sample under Brazilian splitting exhibits similar curve trends, but with increased failure displacement and greater curve nonlinearity. DTS decreases exponentially with increasing heat-treated temperature, while BTS first slightly drops and then significantly declines. Notably, thermally-damaged crystalline rock exhibits a negative Poisson's ratio, causing dog-bone shaped samples to extend laterally under tension and disc-shaped samples to contract bilaterally near its compressive zones. Both phenomena, especially the latter, counteract tensile strength reduction due to thermal damage. With varying heat-treated temperatures, the DTS/BTS ratio decreases exponentially, and the difference between BTS and DTS follows a Gaussian distribution. We shed light on distinct NPR effects in thermally-damaged crystalline rocks under direct tension and Brazilian splitting, clarifying their impact on DTS, BTS, and their disparities.

Published: January 2025

The effective management of urban transport is contingent upon a profound comprehension of the dynamic nature of traffic patterns, alongside the implementation of strategies that are bespoke to the circumstances in question. The growth of urban areas and the increased mobility of individuals have resulted in significant increases in traffic demand, frequently leading to congestion within constrained infrastructure. Cram school districts are particularly susceptible to congestion due to the considerable influx of students and parents, which serves to exacerbate existing traffic issues. The efficacy of traditional methods, such as road expansion, improved public transport, and stricter parking enforcement, in addressing the core causes of congestion has been limited. The objective of this study is to mitigate congestion by identifying optimal pick-up and drop-off (PUDO) zones using the Maximal Covering Location Problem methodology, which considers both pedestrian mobility and network nodes. A social cost analysis of parking facilities and PUDO zones revealed that the latter could reduce social costs by up to 172.3 million KRW. This research is therefore anticipated to alleviate congestion, reduce social costs, and enhance transportation efficiency in cram school districts. The findings may also be applicable to other areas with high demand, thereby offering broader benefits.
Autoimmune Tubulopathies
Authors: Houillier Pascal , Prot-Bertoye Caroline
Published: January 2025

The renal tubule and collecting duct express a large number of proteins, all having putative immunoreactive motives. Therefore, all can be the target of pathogenic autoantibodies. However, autoimmune tubulopathies seem to be rare, and we hypothesize that they are underdiagnosed. This review summarizes the current knowledge on autoimmune tubulopathies. We elected to classify tubulopathies according to the segment that is targeted because this determines, at least in part, the phenotypic presentation. In the proximal tubule, autoantibodies can cause anti-brush border antibody disease, renal Fanconi syndrome, renal proximal tubular acidosis, or tubulointerstitial nephritis and uveitis syndrome. Autoantibodies targeting the thick ascending limb of the loop of Henle can cause either acquired Bartter syndrome or hypomagnesemia with hypercalciuria, whereas autoantibodies targeting the distal convoluted tubule can cause acquired Gitelman syndrome. Finally, renal distal tubular acidosis or nephrogenic diabetes insipidus can be caused by autoantibodies targeting the collecting duct. In most instances, the characterization of the autoantibodies remains incomplete and the pathogenesis of the disease obscure. We believe it is important to increase the awareness of physicians regarding autoantibody-mediated tubular diseases to have a better estimation of the prevalence and to improve the care to patients. A research effort to increase the understanding of the pathogenesis of autoantibodies-mediated tubular diseases is also hoped for.
The role of leadership in technology adoption in the South African mining industry
Authors: Mokganya P.J. , Webber-Youngman R.C.W. , Uys J. , Olwagen J.
Published: January 2025

This article discusses the critical role of leadership in the technology adoption process within organizations, particularly in industries like mining, where innovation is essential for maintaining competitiveness and operational efficiency. It highlights the limitations of traditional technology adoption models, such as the Technology Acceptance Model (TAM), Diffusion of Innovations (DOI), and Unified Theory of Acceptance and Use of Technology (UTAUT), which focus on individual factors and overlook the strategic and organizational roles of leadership.
The study proposes the Ambidextrous Leadership-Technology Adoption (ALTA) model, which integrates leadership styles such as transformational, transactional, adaptive, and ambidextrous leadership into the technology adoption process. The model emphasizes the balance between exploration (fostering innovation) and exploitation (ensuring operational efficiency). The findings suggest that transformational leadership fosters innovation by encouraging risk-taking and creativity, while transactional leadership ensures efficient technology integration.
The article also identifies key barriers to technology adoption, such as organizational resistance to change, which can be mitigated through adaptive leadership that addresses employee concerns. The research emphasizes the importance of a supportive organizational culture and cross-functional collaboration, which are essential for successful technology adoption. The study concludes by offering practical recommendations for leaders to foster a culture of innovation, manage resistance, and balance short-term efficiency with long-term technological advancement.
Investigating the effect of different loading scenarios on the performance of wheel loaders: A case study on Can Lignite Enterprises
Authors: Çelik A.
Published: January 2025

Wheel loaders are widely used in many sectors due to their mobility, operational flexibility, and low costs. The literature is mainly focused on improving the hydraulic, mechanical, and electronic subsystems of these machines in terms of efficiency or developing strategies for controlling these systems. In this study, the effects of the loader operator and different working conditions on the loading performance were investigated. The study was carried out at the Can Lignite Enterprise (CLI), which is a major coal producer in Turkey. In the study, which lasted approximately four months, a total of 808 measurements were performed to investigate seven different scenarios. The effect of a single parameter on loading performance was investigated in the first six scenarios. The results showed that the biggest impact on loading performance was caused by the operator's experience with 63.4%. On the other hand, the worst and most ideal working conditions determined from the first six scenarios were tested in the seventh scenario. It was tested as a script. The test results showed that the loading performance was 285.5% more effective under the most ideal operating conditions compared to the worst operating conditions. In addition, in the study, the loading performances of five loaders with four different capacities were examined in terms of energy efficiency and it was determined that the Kawasaki 115 work machine, which has a higher model and lower engine operating hours, was more advantageous. In the study, various suggestions were developed in parallel with the research results. The most prominent and easiest to implement of these suggestions is related to the selection of the loader operator.
Pillar design and the associated mining engineering constraints in hard rock bord-and-pillar mines
Authors: Theron W.J. , Malan D.F.
Published: January 2025

Practical mining aspects should be considered when conducting pillar designs for bord-and-pillar layouts. The current methodology for pillar design will result in increasing pillar sizes with depth. This affects the extraction ratio and will result in onerous ventilation requirements when cutting large pillars. A holistic approach, including all mining engineering requirements, is required to ensure that the rock engineering designs are optimized to ensure efficient mining operations and sustainable production. Bord widths should not only be a function of the rock mass ratings, but should also be selected to fit the specifications of the mechanized equipment. The use of a 'squat pillar' formula for hard rock is discussed in the paper and the formula based on the exponents of the Hedley and Grant pillar formula, is explored. The effect of abutments and geological losses on average pillar stress is also explored. These factors must be considered when designing layouts at increasing depths.

Published: January 2025

This article presents inspection of facades in two buildings: Sergadas Vianna and SulAmérica. Both buildings are located in the São José neighborhood, in Recife/PE, within the perimeter of one of the Historic and Cultural Preservation Zones in the city center and are representative examples of modern architecture. The present facades were investigated using a Remotely Piloted Aircraft (ARP), carrying out data surveys and preparing damage maps, showing the presence of dirt, concrete spalling, paint detachment, as well as exposed armor with corrosion. The aim of the article is to develop a method for the accurate identification and diagnosis of these pathological manifestations, providing a solid basis for structural maintenance and rehabilitation. The results obtained with the use of ARP facilitated and accelerated the mapping of facades, being precise in identifying each type of pathological manifestation, which provides a comprehensive view of the conditions of the buildings, facilitating informed decision-making for maintenance and repair interventions. The application of these innovative approaches in the field of civil engineering promotes efficiency in the management of urban and historic buildings, contributing to durability, safety, long-term preservation and analysis of the impact of the building's state of degradation on the integrity of the asset as a property that has cultural value.

Published: January 2025

El compliance organizacional tradicionalmente se enfoca en prevenir delitos internos y evitar sanciones por incumplimientos. Sin embargo, carece de una visión holística. Se ha desarrollado un método que analiza las obligaciones de cumplimiento considerando aspectos ambientales, económicos, sociales y culturales. Este enfoque se aplicó al sector notarial en Nayarit; y se demostró su aplicación sistémica. Se creó un método para identificar las obligaciones sistémicas a partir de los riesgos de compliance aplicable a diversas organizaciones. Al aplicarlo al sector notarial en Nayarit, se identificaron 155 obligaciones de cumplimiento, cabe destacar que el 47 % derivan de la relación económico-social y el 45 % de la relación social-cultural. No se encontraron obligaciones ambientales, lo que indica una oportunidad de mejora en este ámbito. Este método permite analizar los riesgos de compliance en cada proceso organizativo y ofrecer una perspectiva integral.
El humor en los tiempos de la cólera. Desbriznando El humor gráfico español del siglo XX para una clase de historia contemporánea en blanco y negro
Authors: Pallarés Jiménez Miguel Ángel
Published: January 2025

Humor gráfico español del siglo XX appeared in 1970 as part of a collection of 100 titles, RTV Books, which was also published as the “Salvat Basic Library”; 96 cartoonists were included in this anthology, some of whom had already worked in the previous century. This selection came to light only four years after the “Press and Print-ing Law” was approved, which signaled a certain openness of the Franco regime; But, even so, the authorities made use of cultural dirigisme to control the contents of the editions or, as in this case, they authorized a list of works whose reading would not cause any political problems.

Authors: Mont Muñoz Ismael
Published: January 2025

Sebastián de Almonacid is one of the most controversial and unknown artists of all those who worked in Castile in the transition from the four hundreds to the five hundreds. In this article we present an unpublished document that records the Good Friday pardon granted in 1492 by the Catholic Monarchs to Sebastián de Almonacid, whom we identify with the Toledo artist of the same name who was active in Castile around 1500. This source sheds new information on the biography of the master, an aspect of great relevance due to the fact that the few references we have about Almon-acid are of a professional nature.
Quarantined Justice, Compromised Diversity: Barriers to Disability Inclusion in China’s Public Sector Employment
Authors: Xue Qian , Chen Bo
Published: January 2025

Under the advocacy for diversity and inclusion within Chinese society, the judiciary has become a significant institution for the protection of marginalized groups, especially disabled people. Through proactive power expansion, the Supreme People’s Court has played a crucial role in scrutinizing employment discrimination in the private sector. However, the judiciary has paid less attention to the fact that government agencies failed to consider the value of workplace diversity and maintained ableist standards that preclude many disabled candidates from public sector positions. Due to the intrinsic political embeddedness within Chinese judicial systems, courts tended to adopt a strategy known as “quarantined enforcement” when confronted with discriminatory recruitment clauses issued by government‐tied entities. Social and political factors collaboratively shaped the intersectional marginalization of the disabled community in China. This article attempts to move beyond traditional legislative‐centric approaches and emphasize the judiciary’s role in minimizing the marginalization of disabled people. It argues that eliminating political barriers within the judiciary is crucial for achieving workplace diversity and employment equality.
A Conjoint Approach to Understanding Software as a Service (SaaS) Adoption Decisions: A Replication Study
Authors: Schwarz Andrew , Hirschheim Rudy , Parekh Harsh , Fulk H. Kevin
Published: January 2025

The decision to source services from cloud computing vendors is becoming increasingly complex. Over time, more IT products, processes, data, information, and security have been offered ‘as a service.’ The present study replicates one by Schwarz et al. (2009) examining the first instance of cloud computing, the Application Service Provider (or ASP), but includes decision-making about Software as a Service (SaaS) to determine whether the drivers of ASP adoption parallel those of SaaS. The findings suggest that despite the similarity in theoretical lenses, there is a shift in resource heterogeneity from one study to the next, specifically how the application differentiates the firm.

The purpose of the article is to provide an assessment of phytochemical studies of the monosaccharide composition of an annual grass of the asteraceae family, common in Ukraine. The wide geographical distribution of Erigeron species from North America to Japan makes it promising to study the depth of the monosaccharide composition of Erigeron annuus. The carbohydrates were separated by gas chromatography-mass spectrometry after conversion into volatile aldononitrile acetate derivatives. The monomeric composition of polysaccharides was studied after their hydrolysis to form monosaccharides and polyalcohols. Quantitative analyses of free carbohydrates showed that the predominant sugars were fructose, glucose and disaccharide – sucrose. The chromatographic study revealed a number of polyalcohols that are important for the treatment and prevention of progression of diabetes mellitus and its complications, namely, mannitol.

Estimating the Coseismic Displacement of Ground Motions with Fling-Step Effect Based on an Intrinsic Timescale Decomposition Algorithm
Authors: Geng Yulong , Pu Wuchuan , Xue Yaohui , Kong Fan
Published: January 2025

Strong ground motions resulting from the fling-step effect often exhibit significant static displacement. However, recorded ground-motion signals may display an unreasonable baseline offset because of contamination by low-frequency (LF) noise. Baseline correction is essential to eliminate this offset while preserving the coseismic displacement component. Many studies have generalized the two-stage offset model and proposed methods for empirically determining the starting times (t1 and t2) of the two stages with different levels of offset. To minimize errors caused by the subjective determination of t1 and t2, this article introduces a novel method for detecting optimal values of t1 and t2 and recovering the coseismic displacement of ground motions. The proposed approach uses an intrinsic timescale-decomposition-based filter to eliminate the LF offset component and introduces a quantitative index to identify the starting time points of the offset. After these time points are determined, the corresponding baseline offset is computed using the two-stage offset model. The effectiveness of this method is validated by comparing its results with the coseismic displacement data recorded by dense Global Positioning System networks during the 1999 Chi-Chi earthquake and the 2011 Tohoku earthquake. In addition, several existing empirical baseline correction methods are assessed. The results confirm that the proposed method effectively removes the baseline offset and accurately recovers coseismic displacement from strong-motion records.

According to this research, AI-driven robots may improve operational efficiency, save costs, and promote sustainability objectives in solar and wind energy system maintenance. The paper examines AI and robotics technology, analyzes their applications in renewable energy maintenance, and identifies difficulties and prospects for maximizing their utilization. Using secondary data, the research synthesizes significant findings and trends from peer-reviewed publications, case studies, and industry reports. Primary results show that AI-driven robots may transform maintenance processes by boosting inspection accuracy, safety, and downtime while meeting sustainability objectives via resource efficiency and waste reduction. High initial costs, technological constraints in severe settings, and regulatory complexity still prevent broad implementation. Policy implications involve focused research and development, consistent rules, and financial incentives to make these technologies more accessible to smaller operators to solve these difficulties. Governments, business leaders, and academics must work together to overcome these challenges and maximize AI-driven robots in renewable energy. This research stresses robots' crucial role in expediting sustainable energy infrastructure transformation.
Using AI Chatbots in Visual Programming: Effect on Programming Self-Efficacy of Upper Primary School Learners
Authors:   Faculty of Education, The University of Hong Kong, Hong Kong SAR, China, Wang Zhaoji
Published: January 2025

Programming Self-Efficacy (PSE) is crucial for enhancing learners’ skills, cognitive abilities, and career interests. Despite its significance, existing research often overlooks strategies to boost PSE among upper primary school learners. This study evaluates the impact of an innovative e-learning tool, AI Chatbots, on students’ PSE. Conducted in a primary school in northern mainland China, the experiment integrated AI Chatbots as an intervention within a visual programming curriculum. It involved 98 fifth-grade students divided into experimental and control groups, both instructed by the same teacher. Interviews were conducted with 6 selected participants from the experimental group after completing all intervention procedures. Findings suggest that, compared to traditional teacher-led instruction, AI Chatbots significantly enhance students’ PSE in programming skill, while boost in PSE in programming knowledge remains non-significant. The study also investigates the mechanisms through which AI Chatbots provide students with easily accessible, personalized learning support for self-directed learning and reduce emotional barriers when they seek help.
Inequality, Education, and Skills in Latin America: Evidence from the Regional Learning Assessment
Authors: Näslund-Hadley Emma , Alonzo Haydée
Published: January 2025

Educational inequality remains a critical challenge across Latin America, with significant learning gaps persisting, particularly among students from marginalized and impoverished communities. Stark inequities in access to quality education and its academic benefits disproportionately affect disadvantaged students, perpetuating exclusion and segregation. This study leverages data from the 2019 Regional Comparative and Explanatory Study (ERCE 2019) to analyze educational outcomes, focusing on the challenges faced by students from low socioeconomic backgrounds and Indigenous communities. Findings reveal that the mathematics achievement gap between students of low and high socioeconomic status widens from third to sixth grade, with Brazil and Uruguay exhibiting the largest disparities. Similar gaps in language and science achievement are evident, particularly in Brazil, Colombia, Guatemala, Panama, Peru, and Uruguay. Indigenous students face additional systemic barriers, with Costa Rica and Panama showing the most pronounced disparities. Using the Oaxaca-Blinder Decomposition method, the study identifies that mathematics and language gaps between Indigenous and non-Indigenous students are partially explained by non-observable factors such as discrimination and bias.
