Universal Karya Jaya is a company engaged in metal cutting services. The company does not have a running Information System yet. Therefore, it is necessary to have a good information system to support its business processes through data warehouse design. The design of the data warehouse uses the nine- step methodology from Kimball and uses star modeling so that PT. Universal Karya Jaya can make their company data integrated and help superiors analyze data for fast and accurate decision making. The goal to achieve from this research is to design a data warehouse model that suits the needs of the company and it is hoped that this design can be implemented at PT. Universal Karya Jaya to support their business processes. Meanwhile, the research method used for this research was literature study and interviews. With this data warehouse, it is hoped that it can assist companies in handling large amounts of data so that it can become a helping hand on inputs for stakeholders in the decision-making process.
Justification of the optimal operating time for the main pumps of a mining hydraulic excavator
Authors: Rakhutin M.G. , Van Hiep Tran , Van Loi Le
Published: May 2024

As the pump operates and wears out, the gap in the friction pairs increases and the volumetric efficiency decreases, the pump flow gets reduced, which leads to increasing duration of working and auxiliary operations, the operating cycle of the excavator, a decrease in its productivity and excessive fuel consumption. Infrequent pump replacement can lead to a significant increase in fuel consumption and reduced excavator performance. If the pump is replaced prematurely, its service life will not be used to the full extent. In order to develop a method for establishing optimal operating hours that allow minimizing fuel consumption and the cost of replacing a pump, taking into account operating conditions, a mathematical model of the pump operation is proposed, which makes it possible to obtain an expression for determining the differentiated optimal value of operating time between replacements. A calculation method and a software algorithm have been developed in the MatLab Simulink software suite to calculate the rate of decrease in the volumetric efficiency, as well as to establish the influence of volumetric efficiency on the fuel consumption and performance of a hydraulic excavator to be utilized in the model using the example of the HPV375 pump of the Komatsu PC2000-8 excavator, Based on the proposed mathematical model of the main pumps operation, a method has been developed for calculating the differentiated operating time between replacements of the main pumps of a mining hydraulic excavator, taking into account the rate of decrease in volumetric efficiency, replacement costs and damage due to changes in productivity and excessive fuel consumption. The dependence of the rate of changes in the volumetric efficiency of the pump is presented for the excavation, viscosity, contamination and temperature of the working fluid parameters. A coefficient of “reserve of partial engine power transferred to the pump” is proposed, determined by the ratio of the difference between the average maximum and initial partial power to the value of the initial partial power, which allows estimation of the operating time of the main pumps without affecting productivity of the excavator.
Policy brief: Learning from Italy to promote sustainability education in Hong Kong
Authors: Lin Lin
Published: May 2024

Education is recognised as an integral part of building the capacity of all ages to drive the transformation toward sustainable development. While the Hong Kong government aspires to achieve carbon neutrality by 2050 and has ramped up efforts to integrate sustainability into school curricula and raise public awareness through educational activities, this policy brief argues that Hong Kong’s existing measures failed to empower and motivate individuals and the community to keep pace with its climate action ambition. Drawing on Sterling's framework of education for sustainability (EFS), this paper presents a diagnosis of Hong Kong’s major problems in sustainability education policies and suggests that the Hong Kong government should learn from the Italian experience to take a more systemic, empowering, and democratic approach in advancing its EFS policies.

Published: May 2024

Domestic swine (Sus scrofa domesticus) are important translational models for cardiovascular transplant studies. This can be attributed to the anatomic and physiologic similarities of their cardiovascular system to humans. Transplant studies frequently employ clinically relevant immunosuppression regimens to prevent organ rejection postoperatively. Immunosuppression can lead to opportunistic infection, including presentations that are novel or poorly described in immunocompetent hosts. In this study, we describe the first case of Mycoplasma hyorhinis–induced endocarditis affecting the pulmonary valve in a juvenile, immunosuppressed pig following a partial heart transplantation procedure. Clinical signs of infection began at 15 d postoperation, were consistent with a variety of infectious agents, including Mycoplasma hyorhinis, and included lethargy, respiratory signs, and elevated white blood cell counts. By 28 d post procedure, lameness and soft tissue swelling around the left tarsus developed. Joint fluid obtained by arthrocentesis was PCR positive for Mycoplasma hyorhinis and negative for other tested pathogens. Despite antimicrobial treatment, the transplanted pulmonary valve developed leaflet thickening, stenosis, and insufficiency starting at 30 d after the procedure. At 86 d posttransplantation, the pig reached experimental endpoints and was humanely euthanized for necropsy and histopathology. The pulmonary valve had numerous dark red vegetative expansions of all 3 leaflets. Postmortem testing of a vegetative lesion was positive for Mycoplasma hyorhinis, confirming the etiologic agent responsible for endocarditis. Mycoplasma hyorhinis–induced endocarditis of an orthotopic transplanted pulmonary valve has yet to be described in swine. This case report demonstrates that infections following immunosuppression may present with novel or undercharacterized clinical signs.
Towards sustainable mangrove-shrimp aquaculture through capacity building and partnership in the Mekong River Delta
Authors: Vo Thu , Le Hue , Phan Diep , Tran Anh , Nguyen Yen , Nguyen Ha
Published: May 2024

Vietnam, the world’s third-largest shrimp producer, witnessed a surge in shrimp farming when rice fields were converted into ponds, aiming to alleviate poverty in the Mekong River Delta (MRD). However, this growth significantly contributed to the decline of mangrove forests, as indicated by empirical and geospatial data. Local authorities have encouraged the application of “International Principles” to promote sustainable mangrove-shrimp aquaculture in MRD provinces. Tra Vinh, a province with a high rate of mangrove-shrimp farming, faces challenges in applying international standards, particularly for small-scale farmers. Understanding the circumstances in Tra Vinh is crucial not only for local farmers but also for stakeholders in the region. An in-depth review, local needs assessment, and a capacity-building program centred on the Asian Seafood Improvement Collaborative (ASIC) standards were conducted in Tra Vinh. The findings suggest that adhering to ecological/organic shrimp farming based on international standards is the right direction for local shrimp farmers. However, increased awareness alone does not guarantee a shift from traditional to internationally certified sustainable shrimp farming. The study highlights the role of private-private partnerships (PPPs) in facilitating the transition to sustainable mangrove-shrimp farming, emphasising that sustainable practices in the MRD are essential for household income, mangrove forest protection, environmental conservation, and climate resilience.
Reconstructing Prehistoric Communities’ Mobility in Apulia
Authors: Filloramo Roberto
Published: May 2024

Reconstructing Prehistoric Communities’ Mobility in Apulia presents pioneering scholarly research to illuminate the interplay between ancient societies and their physical environment during the Neolithic to Early Bronze Age. The study introduces novel methodologies and analytical frameworks, yielding insights into the dynamics of prehistoric settlement patterns. To explore these dynamics, a systematic database was created containing comprehensive information about the archaeological sites, thus serving as the foundation for validation and classification, guided by a purpose-built model. A core investigation of the text is the Mobility Analysis (Least Cost Path), which hypothesises how communities maintained connections through time, whether for trade, ideas, or interpersonal exchanges. The other main aspect is the Landscape Perception (Fuzzy Viewshed Analysis), which deciphers how groups perceived and controlled their surroundings through sight. The research outcomes provide insight into settlement decisions, reflecting the evolution of the socio-economic relationships.

Effect of apple pomace degraded by Pleurotus ostreatus on growth and meat quality parameters of broiler chickens
Authors: Buglione M. B. , Cayolo F. , Maldonado J. F. , Filippi M. V. , Martínez D. A.
Published: May 2024

The objective of this work was to compare the growth and physicochemical parameters of the meat of broiler chickens (Gallus gallus), fed with a supplemented diet (SD) consisting of 3% pleurotin, compared to those obtained when using a traditional diet (CD). Pleurotin is the remaining material from the biodegradation of substrates such as apple pomace used to cultivate the Pleurotus ostreatus fungus. The experience lasted 48 days and in the first eight days, the birds were divided into two groups of 24 individuals, one group for each treatment. On day 12, each initial group was subdivided into four experimental units (replicates) of 6 chickens each. The growth parameters measured were total weight gain (TWG), final live weight (FLW), carcass weight (CW), average daily gain (ADG) in weight, and feed conversion ratio (FCR). Physicochemical parameters such as pH, water content (WC), CIE color, total fat (TF), and fatty acid composition (FAC) were also measured. Statistical analysis was carried out through the t-Student independent samples test. FLW was on average 7.6% significantly higher with SD than with CD, however, no difference was detected in CW. The total ADG was 7.4%, significantly higher with SD while the FCR was 32.0% lower with SD than with CD. No significant differences were found in any of the meat quality parameters measured for the same piece. Despite these latest results in terms of meat quality, it is concluded that the increase found in total ADG and FLW, and an improvement in FCR values with SD favor the use of this amendment in chicken rearing. In addition, the introduction of the by-product of the juice industries of the Río Negro Valley in other production cycles, such as edible mushrooms production and a supplement for bird diets (pleurotin), promotes a circular bioeconomic mechanism.

Published: May 2024

El objetivo del presente estudio fue evaluar la Tasa de Fecundación in vitro de ovocitos bovinos con semen sexado (SX) y convencional (Conv.) capacitados (B.O y Percoll) con la técnica Swim-Up. Se evaluó el clivaje a las 48 horas post fecundación y al séptimo día del desarrollo embrionario. Los resultados mostraron un porcentaje de clivaje del 59,4% en el T1 (Conv. Percoll), 60% en el T2 (Conv. B.O), 75% en el T3 (SX. Percoll) y 46,6% en el T4 (SX. B.O), mostrando diferencia estadística entre T3 y T4 (p>0,05). La tasa de desarrollo del embrión al séptimo día fue 34,4% T1, 20% en T2, 15% en T3 y 10,51% en T4; en este caso, se encontró diferencia estadísticamente significativa en el uso del medio convencional más Percoll en comparación con el medio de SX B.O (p<0,05) (T1 y T4, respectivamente). Los resultados también mostraron una producción similar de mórulas y blastocitos tempranos y protruidos entre los cuatro tratamientos, y demuestran la viabilidad del desarrollo e implementación de la técnica de fertilización in vitro (FIV) para producir embriones bovinos. Concluyendo la evaluación preliminar, destaca la significativa influencia del método de sexado y del tratamiento en la calidad del semen y desarrollo embrionario en programas de reproducción animal. Aunque el semen sexado con Percoll muestra potencial para mejorar tasas de clivaje, el semen convencional, especialmente en el tratamiento T1 (Conv. Percoll), exhibe una superioridad en motilidad individual y concentración. Estos resultados informan decisiones cruciales para optimizar programas reproductivos.

LOGISTICS SYSTEM OF QUALITY MANAGEMENT OF ROAD TRANSPORT SERVICES
Authors: KRYVORUCHKO O. , KRYVENKO L.
Published: May 2024

The development and implementation of logistics systems for managing the quality of transport services is important and expedient from the point of view of ensuring customer satisfaction (quality management makes it possible to ensure high quality of transport services, which, in its turn, leads to customer satisfaction), effective use of resources during the provision of transport services, increasing efficiency and productivity of production processes and application of innovative technologies. Quality management of transportation services includes regular monitoring of service quality, collection and analysis of data on customer requirements, customer satisfaction, investigation of emerging problems and their resolution.
The analysis of existing theoretical provisions and practical experience regarding the integration of quality management and logistics activities showed that insufficient attention has been paid to this issue. The theoretical aspects of implementing an integrated approach to the creation of a logistics system for managing the quality of transport services, as well as the definition of the main principles of its formation and implementation, require clarification.
The article substantiates the expediency of applying a systemic approach to the integration of logistics and quality management of transport services and logistics service, and specifies the composition and interrelationship of the elements of the logistics quality management system.
Logistics management of the quality of transport services involves activities to ensure the required level on the basis of consumer requirements and directions for increasing the efficiency of using financial, material, personnel and information resources. The main provisions of the logistic approach to the management of the transport services quality are as follows: application of the process approach to the logistics flow and the flow of quality formation; the principle of complexi­ty; optimization of logistics flows and flows of quality formation based on interaction and synergy.
A scheme of a system approach to the integration of logistics and quality management at the enterprise has been developed. The composition of the logistics system elements for managing the quality of transport services is substantiated.
The directions of further scientific research are the development of functions and implemen­tation mechanisms of the proposed logistics system for managing the quality of transport services.

Published: May 2024

The article is devoted to the study of current issues related to the implementation of a modern competence approach in personnel management of enterprises and organizations in various industries. A scientific survey of the latest achievements of leading scientists and practitioners on the issue of building a model of employee competencies was carried out, as a result of which the need was established to refine the issue of ordering and applying separate approaches to the formation of such models, as well as establishing their constituent elements.
In the course of the analysis and generalization of the latest academic achievements, published in a number of modern sources, the main existing approaches to building a model of employee competencies are highlighted, among which the most appropriate, according to the authors, is the creation of a completely new model. At the same time, a critical review of meaningful developments and acquisitions of specialists in this field was carried out to highlight the components of the competency model that form its structure. It was found that they are quite different, include a various number of structural elements of different content, which causes the need for their argumentation and systematization.
The main goal of the article is to analyze and organize the used approaches to the formation of the employee competencies model, as well as to substantiate the total number of its constituent elements.
After their comprehensive analysis, comparison and synthesis, as well as based on previous studies, the principles of building a model of employee competencies were formulated. It is substantiated that when choosing a rational approach to the development of an employee competencies model, it is advisable to choose the creation of a completely new model, in which the factors that have the greatest influence on its content will be fully taken into account. Based on a critical analysis of existing achievements, separate models of competences have been developed for employees of different categories (positions), which, unlike the existing ones, fully cover the entire set of necessary competencies and characterize them in various ways.
The outlined studies serve as a basis for the development of methodological recommendations and the corresponding tools for their practical application in the development of the employee competencies model.
fabOF: A Novel Tree Ensemble Method for Ordinal Prediction
Authors: Buczak Philip
Published: May 2024

Ordinal responses commonly occur in the life sciences, e.g., through school grades or rating scales. Where traditionally parametric statistical models have been used, machine learning (ML) methods such as random forest (RF) are increasingly employed for ordinal prediction. As RF does not account for ordinality, several extensions have been proposed. A promising approach lies in assigning optimized numeric scores to the ordinal response categories and using regression RF. However, these optimization procedures are computationally expensive and have been shown to yield only situational benefit. In this work, I propose Frequency Adjusted Borders Ordinal Forest (fabOF), a novel tree ensemble method for ordinal prediction forgoing extensive optimization while offering improved predictive performance in simulation and an illustrative example of student performance.
The Scarborough Survey: An interdisciplinary hybrid instrument to explore suburban challenges in Canada
Authors: Tiznado-Aitken Ignacio , Farber Steven
Published: May 2024

While urban regions continue to grow, much of the urbanization that is occurring is better described as suburbanization. This is generating and will continue to generate immense pressure on our social and environmental systems. To address these challenges and exploit specific suburban opportunities, cities globally require a complete understanding of the complexity of how human and environmental systems are uniquely intertwined within suburban contexts. The Suburban Mobilities (SuMo) cluster at the University of Toronto Scarborough (UTSC) aims to address these academic and policy challenges, generating transformative, interdisciplinary, partnered research about suburban contexts that will allow communities to solve holistic transportation challenges facing the suburbanized world in the 21st century.Among the multiple projects developed within the SuMo cluster, one highlight is the design of a multidimensional survey in Scarborough, an eastern suburb of Toronto, Canada. Multiple transportation, land use, pricing and census data sources have allowed us to characterize this area to date, and we wondered what information would be helpful to collect in a survey to fill data gaps that will enable a better and deeper characterization of transportation’s impacts on quality of life of people living in Scarborough. This article details the particularities of the Scarborough context, as well as the design process, sampling strategy, representativeness, main descriptive results, and ongoing work using the survey. Finally, a reduced and aggregated survey version is available for the general public with respective documentation for ease of use.
Negative emotional events retroactively disrupt semantic scaffolding of temporal memory
Authors: McClay Mason , Rouhani Nina , Clewett David
Published: May 2024

Emotional responses pervade everyday life and exert temporally extended effects on cognition. Prior work shows that these modulatory effects of emotion on memory are highly selective, with semantic overlap helping to determine which nearby neutral details are prioritized in long-term memory. Although this has been demonstrated in item recognition, less is known about how emotion interacts with semantic information to influence temporal memory. Here, we developed an emotional oddball task in which participants encoded lists of neutral words that were either semantically related to or unrelated to a perceptually deviant emotional or neutral oddball word. We hypothesized that an adaptive memory system should selectively enhance temporal order and recall memory for information that precedes or follows a conceptually related emotional stimulus. We found that order memory was enhanced for word pairs that preceded a semantically related neutral oddball, suggesting that semantics helps to scaffold temporal encoding processes. By contrast, emotional oddballs retroactively disrupted this mnemonic benefit of semantic overlap on temporal memory. Emotional oddballs also led to proactive impairments in order memory irrespective of semantic relatedness. After a 24-hr delay, emotion enhanced recall of preceding, semantically unrelated words. Encountering an emotional oddball also enhanced recall for subsequent words irrespective of semantic relatedness. Our findings suggest that emotion bidirectionally and selectively disrupts the temporal organization of memory, while also enhancing memory for individualized, unrelated elements of an emotional episode.
Love on the Spectrum: A Preliminary Investigation of the Links Between ASD Diagnosis and Romantic Love in Young Adults Experiencing Romantic Love
Authors: Bode Adam , Kowal Marta
Published: May 2024

Autism Spectrum Disorder (ASD) is a neurodevelopmental condition with heterogeneous expressions and associated difficulties. While there is evidence that individuals diagnosed with an autism spectrum disorder face specific challenges in relation to establishing and maintaining romantic relationships, to our knowledge, no one has investigated the expression of romantic love in this population. Drawing on a sample of 810 young adults from the Romantic Love Survey 2022 (32 diagnosed with ASD), we calculated independent sample effect sizes to investigate differences in number of times ever in love, when participants fell in love relative to when they started their romantic relationships, intensity of romantic love, obsessive thinking about a loved one, commitment, and frequency of sex between individuals who have and have not been diagnosed with ASD. We only found small but not significant effects of commitment and frequency of sex. These preliminary findings suggest that individuals diagnosed with ASD may experience romantic love similarly to those not diagnosed with ASD. There was, however, some indication that individuals diagnosed with ASD may be less likely to progress their romantic relationship to a stage when they are having sex until they are in a committed relationship. This study can be used to help guide future research efforts and provide evidence that may be of comfort to some people diagnosed with ASD.
Wellbeing and Prosocial Crowdfunding for Achieving Sustainable Development Goals
Authors: Raghavan Ramya
Published: May 2024

In current crowdfunding literature, the connection between fund providers and Sustainable Development Goals (SDG) is highly significant. Prosocial behaviors and social cohesion can be predictors of crowdfunding for SDGs. Subjective choices in crowdfunding do not appear to be influenced by educational or income level, suggesting that individual differences in decision-making play a role. Prosocial behaviors have been analyzed within the framework of unity, expressing a sense of social responsibility and belonging. Prosocial behaviors are therefore seen as being linked to social cohesion and their impact on SDGs.

Published: May 2024

Lightning protection system (LPS) as per IS/IEC 62305 is mandatory in India for buildings above 15 meters and for special buildings like educational institutions, and hospitals regardless of their height. External LPS (ELPS) can be of isolated or non-isolated type depending upon the nature of the structure. This paper reviews the installation of ELPS before and after the publication of the National Building Code of India 2016 (NBC). This is limited only to ELPS and Internal Lightning protection system (ILPS) is not considered. The installation has been studied as per IS/IEC 62305 on electrical isolation. The conclusion has been drawn based on the installation and the influence of NBC 2016.
Smart EV Charger With Reactive Power Compensation and Surge Protection
Authors: Bhandari Nirajan , Pandey Pratik , Adhikari Bibek , Dhungel Ashish , Thapa Deepak , Ghimire Ankit
Published: May 2024

The paper proposes integrating compensating functions into fast EV charging stations to enhance grid reliability and reduce reliance on costly devices like STATCOMs and Capacitor Banks used to solve voltage drop issues caused by EV adoption. The developed smart fast EV charger functions as a boost rectifier while simultaneously providing surge protection and compensating reactive power in the grid during charging. Using a cross-coupling strategy, a PID controller manages the leading current to supply reactive power to regulate voltage at the connection node. An ILPS with SPD safeguards the charger from lightning or other induced surges. The charger can operate in three modes: charging the battery at unity power factor, acting as a STATCOM without connecting the battery, or charging the battery while supplying reactive power to the grid in a bidirectional manner.

Authors: Gyawali Shriyog Sharma , Bhusal Ramji Jaisi , Sharma Shriram
Published: May 2024

Forest fires have emerged as a significant and pressing issue in Nepal, jeopardizing its natural ecosystems, biodiversity, and communities. While human activities have been traditionally linked to these fires, this study explores the potential impact of lightning strikes, a natural factor that could contribute significantly to the problem. Using data from Vaisala's Global Lightning Dataset (GLD 360) and the Moderate Resolution Imaging Spectroradiometer (MODIS) dataset, we investigate the relationship between lightning strikes and forest fires over the five years’ period from 2015 to 2019. Advanced tools like ARC GIS and Python are employed for analysis. Preliminary findings indicate a noteworthy correlation, particularly during the pre-monsoon season. This investigation shows an interesting fact that positive lightning strokes are more likely to initiate forest fire as compared to their negative counter parts. This research offers a fresh perspective on lightning-induced forest fires in Nepal, paving the way for targeted fire management strategies and further investigation into lightning ignition mechanisms.

Published: May 2024

INTRODUCTIONJapanese encephalitis virus (JEV) is a ﬂavivirus, is the main cause viral encephalitis, endemic in South-East Asia, and Western Paciﬁc regions and has become a major public health problem worldwide. JEV is transmitted to humans through the bite of an infected mosquito, mainly Culex tritaeniorhynchus that breeds in ﬂooded rice ﬁelds, marshes, standing water around planted ﬁelds. Reservoir hosts are Adreid birds (herons and egrets), and pigs serve as ampliﬁer hosts. Though infections are usually asymptomatic, the symptomatic Japanese encephalitis has a case fatality rate as high as 30%. Permanent neurologic or psychiatric sequelae can occur in 30-50% of those with encephalitis. There is no antiviral drug available. Treatment is mainly supportive and symptomatic. Safe and effective vaccines are available to prevent Japanese encephalitis. This article reviews recent advancements in diagnostic methods, prophylactics as well as therapeutic options and challenges to combat this zoonotic emerging and remerging viral encephalitis.

Authors: Sharapov I. I. , Sharapova Yu. A.
Published: May 2024

The current paper has presented the three-year study results (2021–2023) on recording the population dynamics of wheat and predatory thrips during the spring-summer vegetation period of winter common wheat in the forest-steppe of the Samara region.

   The purpose of the study was to determine the dynamics of the seasonal development of wheat and predatory thrips according to the phenophases of the development of winter common wheat in the forest-steppe of the Samara region.

   For this purpose, there were carried out the calculations using the mowing method with an entomological net on winter wheat crops in different phenophases of development, and the population of species and thrips were determined in the laboratory under a binocular. According to weather conditions, 2021 and 2023 were characterized as dry and hot, 2022 was characterized as cool with plenty of precipitation in the first half of the winter wheat vegetation period. The population dynamics of wheat and predatory thrips varied depending on the weather conditions of the spring-summer period of the year. In the hot years of 2021 and 2023 there were 2 periods of increase in population. In 2021, the period of maximum population of wheat thrips was observed from a heading stage to a flowering stage (1016 and 1048 specimen per 100 sweeps of the net) and in the phase of milky-wax ripeness (426 specimen per 100 sweeps of the net). In 2022, the population of wheat thrips on plants increased gradually, the peak was noted once during the flowering stage, amounting to 1084 specimen per 100 sweeps of the net. In 2023, a population increase was observed in the heading stage (1782 specimen per 100 sweeps of the net) and the phase of milky-wax ripeness (421 specimen per 100 sweeps of the net). In the hot years of 2021 and 2023 there were 2 periods of increase in predatory thrips’ population; the maximum number of entomophages was observed during the heading stage and amounted to 87 and 61 specimens per 100 sweeps of the net, respectively. In the cool year of 2022, there was one population increase during the flowering stage and amounted to 14 specimens per 100 sweeps of the net. In the phases of heading and flowering of plants, there were predominantly adult insects (imago), and in the phases of milky and milky-wax ripeness, there were predominantly found larvae of different ages. The weather conditions in 2021 and 2023 turned out to be more favorable for the development of wheat and predatory thrips than in 2022.

Published: May 2024

Currently, the agricultural market offers a wide range of winter wheat varieties of domestic breeding. However, due to climate warming and the increasing frequency of arid years, it is urgent to develop varieties with wide adaptability, large productivity potential and grain quality.

   The purpose of the current study was to identify new genetic sources of winter common wheat with a complex of favorable gene alleles that control grain quality traits. In 2022–2023 there was studied the collection of 26 winter common wheat varieties from breeding institutions of the Rostov region and Krasnodar region using generally accepted breeding techniques.

   There was carried out an analysis of technological quality traits and identification of loci associated with these traits using KASP-markers developed at the Institute of Plant Biology and Biotechnology (Kazakhstan). The varieties developed by the Federal Rostov ARC generated the largest productivity (341 g/m2) with less accumulation of protein and gluten (14.2 and 29.5 %), and, on the contrary, the varieties of the ARC “Donskoy” and the National Grain Center named after P. P. Lukyanenko were characterized by higher percentage of protein and gluten (15.5–15.7 and 33.2–34.4 %), but lower productivity (244–276 g/m2). The varieties ‘Donskoy Mayak’, ‘Konkurent’, ‘Nakhodka’, ‘Rostovchanka 7’, ‘Duplet’ and the line ‘K 18918’ were distinguished by the best technological traits of grain (protein >15 %, gluten > 30 %, gluten index > 85 % and sedimentation ≥ 53 %) and many favorable alleles of SNP loci associated with these features. The varieties ‘Donna’, ‘Zolushka’, ‘Donskaya Lira’ exceeded the standard ‘Omskaya 4’ (368–378 g/m2) in productivity, but their allelic variants of the identified markers were lower. There have been identified the varieties ‘Donna’, ‘Zolushka’, ‘Donskaya Lira’ (Federal Rostov ARC), ‘Donskoy Mayak’, ‘Konkurent’, ‘Nakhodka’, ‘Rostovchanka 7’ (ARC “Donskoy”), ‘Duplet’, ‘line K 18918’ (“National Grain Center named after P. P. Lukyanenko”) with the maximum number of favorable alleles (10–11), associated with technological quality traits, recommended for improving winter wheat varieties in terms of grain quality.

Проаналізовано динаміку показника термостійкості (за Мартенсом) композиту при збільшенні вмісту поліефірної смоли у епоксидному олігомері до q = 120 мас.ч. та встановлено оптимальний вміст поліефірного зв’язувача. Досліджено зміну показників термічного коефіцієнту лінійного розширення (ТКЛР) епоксиполіефірного композиту у різних температурних діапазонах та лінійну усадку від вмісту поліефірної смоли. Експериментально доведено, що при введенні Norsodyne O 12335 AL у кількості q = 10–20 мас.ч. формується композитний матеріал, який характеризу-ється мінімальними показниками ТКЛР у діапазонах: у області ΔТ = 303–323 К – α =1.610-5 К-1, у області ΔТ = 303–373 К – α =(2.0–2.5)10-5 К-1, у області ΔТ = 303–423 К – α =(3.8–3.9)10-5 К-1, у області ΔТ = 303–473 К – α =(8.8–8.9)10-5 К-1. При цьому показники лінійної усадки зменшуються порівняно з епоксидною матрицею від Δl = 0,32 % до Δl = 0,13–0,14 %. Проаналізовано, що отримані значення ТКЛР, лінійної усадки корелюють із показниками термостійкості (за Мартенсом) та із попередньо дослідженими значеннями фізико-механічних властивостей. Встановлено склад епоксиполіефірної матриці, який у комплексі відрізняється підвищеними показниками теплофізичних властивостей. На основі отриманих результатів розроблено епоксиполіефірну матрицю, яку запропоновано використовувати при формуванні захисних покриттів для елементів засобів транспорту, що експлуатуються в умовах впливу змінних та підвищених температур.
International practices in the development of administrative legal relations in the field of child protection

Published: May 2024

Ensuring and protecting children’s rights is a priority in building harmonious legal relations in everycivilisedcountry. Thestudyoftheexperienceofdifferent countries regarding the specifics of the development of administrative legal relations in the field of child protection allows analysing the problematic aspects and identifying positive developments that should be adopted and disseminated. The purpose of this study is to investigate administrative legal relations in the area of child rights protection in certain countries of the world. A set of methods was employed, including methods of induction and deduction, analysis and synthesis, comparison and generalisation, etc. The study examined the content of certain provisions of the Convention on the Rights of the Child, as well as the specific features of legal relations existing between the bodies and institutions of the United Nations. The study analysed the specifics of the development of administrative legal relations in the countries of the Anglo-Saxon and Romano-Germanic legal systems. It was emphasised that in each of the countries under consideration, ensuring and protecting children’s rights is a priority for the state. Even though an effective mechanism for ensuring children’s rights has been developed in countries with highly developed economies and legal culture, certain elements of ensuring children’s rights still need to be improved. The legal relations between different state structures for the protection of children’s rights in the United States of America, England, Germany, France, and Romania are investigated and systematised. Based on the study conducted, a classification of the system of development of administrative legal relations in the area under study was proposed. In addition, the similarities and differences in the development of administrative legal relations for the protection of children’s rights in countries with different legal systems, legal cultures, levels of economic development and mentality were generalised, with author’s generalisations and proposals. The proposed scientific study can be used by researchers as a basis for further scientific investigations, by teachers of higher education institutions, as well as by employees of social services for children and representatives of public authorities who influence the development of state policy on the protection of children’s rights
Indirect emission accounting and effectiveness of market regulation toward sustainability
Authors: Szendrey Orsolya , Dombi Mihály
Published: May 2024

The consideration of sustainability aspects has become increasingly essential and explicitly required by regulatory bodies and financial market participants so that efforts for mitigating climate change and avoiding a global ecological collapse could be strengthened. However, the methods used to measure transition risks do not always adequately describe the relationship between financial assets and environmental pressures. The currently implemented methods are limited to assessing the risks of financial portfolios based on their industrial sector classification and consider only direct emissions. In contrast, Scope 3 effects, which account for a significant part of total emissions, are excluded from the calculations. To reveal how reliable recent knowledge on climate risks is, in this study we investigate the currently used methods of climate exposure evaluation and conduct an analysis for the EU-27 countries by extending the calculation to indirect impacts. Our calculations reveal that the most affected industries are hotels and restaurants, construction, manufacturing, and other services, in which overall emissions are seven times higher on average than direct values. These results also suggest that the aforementioned segments need different risk assessments and additional examinations as part of investment and lending processes.

It has been presented the results of studies on reducing the average density of ceramic wall materials through the use of ash granules. The chemical, granulometric, and mineral compositions of clay raw materials and fly ash are given. It has been considered the compositions of ceramic charges with different contents of thermal power waste and sample preparation techniques. In the first case, mechanical mixing of the charge components was used, in the second case, granulation of the components and creation of a shell on the surface of the granules was used. The physical and mechanical properties of ceramic samples produced by both methods are presented. It has been established that an increase in the fly ash content in the charge leads to a decrease in the average density and compressive strength of ceramic samples. The use of the developed method for producing ceramic materials increases the strength characteristics of the samples, which makes it possible to increase the content of the ash component to 70–80 wt. % in the composition of the charge. It has been shown that the content of fly ash in the charge is more than 60 wt. % leads to an increase in water absorption of more than 20%, which practically indicates the absence of sintering processes in ash granules. Prospects and main directions for further research are formulated.
FROM ANTIQUITIES TO HERITAGE
Authors: Eriksen Anne
Published: May 2024

Eighteenth-century gentleman scholars collected antiquities. Nineteenth-century nation states built museums to preserve their historical monuments. In the present world, heritage is a global concern as well as an issue of identity politics. What does it mean when runic stones or medieval churches are transformed from antiquities to monuments to heritage sites? This book argues that the transformations concern more than words alone: They reflect fundamental changes in the way we experience the past, and the way historical objects are assigned meaning and value in the present. This book presents a series of cases from Norwegian culture to explore how historical objects and sites have changed in meaning over time. It contributes to the contemporary debates over collective memory and cultural heritage as well to our knowledge about early modern antiquarianism.
Kashmir Conflict after Article 370 and 35 A: Challenges and Options for Pakistan
Authors: Adil Nosherwan , Sultan Raja Muhammad Yasin
Published: May 2024

This research explores the complex dynamics of the Kashmir Conflict following the abrogation of Article 370 and Article 35A by the Indian government on August 5, 2019. The historical roots of the incessant dispute, stemming from the British partition of the Indian Sub-continent, set the stage for ongoing tensions between two regional arch-rivals, Pakistan and India over the region. The revocation of constitutional provisions granting special privileges and autonomy to Jammu and Kashmir presents various challenges for Pakistan. Internal security concerns, diplomatic isolation, humanitarian issues, and economic implications form critical challenges. The options of Pakistan include bilateral talks, diplomatic engagement, humanitarian initiatives, promoting internal reforms, and regional stability. Balancing these challenges and options requires navigating a complex geopolitical and strategic landscape, recognizing historical grievances, and fostering peace and stability in the region.

Afghanistan has remained under the rule of different powers but none of them could completely control it and had to leave it for different reasons. World powers had a keen interest and intervened in the state but could not stay there for long. This study has mainly focused on exploring the main causes behind the US withdrawal from Afghanistan. The study was conducted using qualitative data from secondary sources. The main causes behind the US failure are a lack of awareness about the Taliban's nature, corruption, US over-confidence improper management of resources etc. The value of the work can be better judged by observing the contemporary complex world where the US has been criticized among the community of nations for its withdrawal and could assign a new role to the US in the near future.
