Gastritis can be defined as histological inflammation of the gastric mucosa. It can be classified according to the time course of the disease as acute or chronic, histological findings, anatomic location, and pathological mechanisms. The objective of this study was to evaluation of serum levels of the proinflammatory cytokines IL-8, IL-17 and IL-22 in Helicobacter pylori infection and their association with the degree of gastritis histopathology in a sample of Iraqi patients. The case-control prospective study consists of 60 patients who attended the Gastrointestinal Tract Center at Al-Kindy Teaching Hospital during the period from December 2019 to April 2020. In addition, the control group included 60 apparently healthy individuals. Biopsies from the gastric antrum and/or body mucosa were used to assess the severity of chronic inflammation, neutrophil infiltration, atrophy, intestinal metaplasia. Serum samples were obtained to determine H. pylori infection, circulating interleukin (IL)-8, IL-17, and IL-22. Results showed that the Patients’ ages with gastritis ranged from 18-75 years. The body mass index revealed that 33.33% of the patients were obese and 35% of them were overweight. Most of the patients with active chronic gastritis and superficial chronic gastritis had positive titers for anti-H. pylori IgG antibody (167.89 ± 3.18 IU/ml) and (150.74± 1.45 IU/ml) respectively, which was significantly different from the control group (4.36 ± 0.29 IU/ml) (P=0.0001). Histopathological analysis showed that all subjects experienced chronic inflammation, while neutrophil infiltration was found 36.66% and there was significant association between serum levels of IL-8, IL-17, and IL-22 with a degree of chronic inflammation and neutrophils infiltration. In conclusion, the most common cause of gastritis was H. pylori with histopathological lesions, showing neutrophils infiltration and chronic gastric mucosal inflammation associated with increased levels of IL-8, IL-17, and IL-22 in serum.

Teori Kepemimpinan Transformasional Bernard M. Bass dan Aplikasinya Dalam Peningkatan Mutu Lembaga Pendidikan Islam
Authors: Roni Harsoyo
Published: June 2023

Effective leadership is needed in order to be able to bring about significant changes in (Islamic) educational institutions in order to improve the quality of their services. One of them is transformational leadership initiated by Bernard M. Bass which is still popular today and continues to be developed and applied to Islamic educational institutions. The results of a search through literature research show that: 1) Transformational leadership inspires followers to commit to the vision and goals of the organization, provides challenges to become innovative problem solvers, and develops the capacity of followers through coaching, guidance, and providing challenges and support; 2) Components of transformational leadership: Idealized Influence (II), Inspirational Motivation (IM), Intellectual Stimulation (IS), and Individualized Consideration (IC); 3) The effectiveness of transformational leadership: increasing creativity, overcoming stress/crisis, implementing change, and developing leaders; 4) Criticism of transformational leadership theory: (a) it is elitist and anti-democratic, and places too much emphasis on the 'heroic' aspect of leadership; (b) has the potential to be abused; (c) personality traits or personal tendencies that may be difficult to change; (d) lack of conceptual clarity regarding the various components of transformational leadership; and (e) the lack of specification of transformational leaders influence followers and under what conditions emerge and are effective; 5) The ability of school/madrasah principals to properly implement Bernard M. Bass's transformational leadership theory through his 4I’s in an Islamic educational institution, will be able to improve the quality of education and make schools/madrasas effective.

A Machine Learning Approach for Gas Kick Identification
Authors: Obi C. E. , Falola Y. , Manikonda K. , Hasan A. R. , Hassan I. G. , Rahman M. A.
Published: June 2023

Warning signs of a possible kick during drilling operations can either be primary (flow rate increase and pit gain) or secondary (drilling break and pump pressure decrease). Drillers rely on pressure data at the surface to determine in-situ downhole conditions while drilling. The surface pressure reading is always available and accessible. However, understanding or interpretation of this data is often ambiguous. This study analyzes significant kick symptoms in the wellbore annulus both under static (shut in) and dynamic (drilling/circulating) conditions. We used both supervised and unsupervised learning techniques for flow regime identification and kick prognosis. These include an artificial neural network (ANN), support vector machine (SVM), K-nearest neighbor (KNN), decision trees, K-means clustering, and agglomerative clustering. We trained these machine learning models to detect kick symptoms from the gas evolution data collected between the point of kick initiation and the wellhead. All the machine learning techniques used in this work made excellent predictions with accuracy greater than or equal to 90%. For the supervised learning, the decision tree gave the overall best results, with an accuracy of 96% for air influx cases and 98% for carbon dioxide influx cases in both static and dynamic scenarios. For unsupervised learning, K-means clustering was the best, with Silhouette scores ranging from about 0.4 to 0.8. The mass rate per hydraulic diameter and the mixture viscosity yielded the best types of clusters. This is because they account for the fluid properties, flow rate, and flow geometry. Although computationally demanding, the machine learning models can use the surface/downhole pressure data to relay annular flow patterns while drilling. There have been several recent advances in drilling automation. However, this is still limited to gas kick identification and handling. This work provides an alternative and easily accessible primary kick detection tool for drillers based on data at the surface. It also relates this surface data to certain annular flow regime patterns to better tell the downhole story while drilling.

Published: June 2023

Anthropogenic CO2 emissions are expected to significantly impact climate patterns, including extreme heat events. The influence of plants on land-atmosphere water and energy exchanges plays a crucial role in shaping these heat extremes. The response of vegetation growth and physiology to elevated CO2, both directly and indirectly, will determine their contribution to future heat extremes. In this study, we employed a suite of CMIP6 earth system models (ESMs) to differentiate between the effects of radiative forcing and vegetation forcing under elevated CO2 background on extreme heat and precipitation events in China. The changes observed can be attributed to CO2 physiological forcing, which reduces transpiration and its related cooling impact, leading to a decrease in clouds and precipitation under 2×CO2 and 4×CO2 scenarios. Our findings indicate that CO2-induced vegetation forcing (VEG) intensifies the frequency and severity of future heatwaves. Additionally, we found that CO2-driven vegetation decreases extreme precipitation and increases dry days numbers in most humid regions of China, despite the increase in transpiration resulting from the saving of soil moisture and aboveground biomass enhancement due to CO2 fertilization.

Published: June 2023

Sleep apnea is a common sleep disorder. To address the characteristics of ECG signals, we introduce a coordinate attention mechanism and propose an automatic sleep apnea classification model (CA-EfficientNet) based on wavelet transform and lightweight neural network. One-dimensional signals were converted into two-dimensional images by wavelet transform and in put into the proposed model for classification. The effects of input time window, wavelet transform type and data balance on classification performance were considered. PhysioNet apnea ECG database was used for training and evaluation. The 3-minute Frequency B-Spline wavelets transform of ECG signal was carried out, and Dice Loss was used to train the classification model of sleep breathing. The classification accuracy was 93.44%, precision was 93.2%, sensitivity was 88.9%, specificity was 96.2%, F1 score was 91%, and most indexes were better than other related work. Wavelet transform and CA-EfficientNet model provide a feasible diagnostic method for automatic classification of sleep apnea.

Published: June 2023

Waste cotton textiles can be decolorized with the NaOH/Na2S2O4 reducing system with mild and effective results. Nevertheless, this system consumes substantial amounts of Na2S2O4, resulting in an inefficient decomposition process. The present study proposed a two-step NaOH/Na2S2O4 method to decolorize the reactive-dyed cotton fabric. The decolorization mechanism of NaOH and Na2S2O4 was investigated based on the decolorization kinetics. The results showed that Na2S2O4 decolorized the dyed cotton fabric more quickly than NaOH. In the reduction system, the decolorization mechanism of NaOH and Na2S2O4 individually followed a three-order kinetic law. During the decolorization process, a hydrolysis reaction between NaOH and cotton fiber destroyed the covalent bond, and a reduction reaction between Na2S2O4 and the dye destroyed the chromophore. The two-step NaOH/Na2S2O4 method improved the decolorization of dyed cotton fabric by reducing the ineffective decomposition of Na2S2O4. Compared to traditional methods, the two-step method endowed the decolorized fabric with a 16% higher CIE L value. Notably, the decolorized cotton fabric retained about 90% of its breaking strength.
A Novel Approach to Green Cloud Computing: QoS-Optimized Load Balancing with Artificial Bee Colony Algorithm
Authors: kumar Dharmendra
Published: June 2023

This paper uses an artificial bee colony algorithm to present a QoS-oriented technique for load balancing in green cloud computing. The proposed technique aims to optimize workload allocation decisions while minimizing energy consumption and carbon emissions and ensuring QoS requirements are met. The technique involves a fitness function that evaluates the fitness of each solution based on a set of QoS and energy consumption metrics. It also involves the ABC algorithm, which generates novel solutions and explores the search space. The algorithm also applies a dynamic threshold-based approach to adjust the threshold values based on the current system load and QoS requirements. Experimental results demonstrate that the proposed technique outperforms other load-balancing techniques regarding QoS and energy consumption metrics. Compared to other load-balancing techniques, the new technique significantly improved response time, throughput, availability, resource utilization, energy consumption, and carbon emissions. The proposed technique is likely to improve energy efficiency, reduce cloud computing's carbon footprint, and meet quality of service requirements.
Characterization of surface properties of Chitosan, Polytetrahydrofuron and their blends
Authors: Tomar Manisha , RS Jagadish
Published: June 2023

In this research characterization of surface properties of chitosan (Ch), polytetrahydrofuron (PTHF) and Chitosan/PTHF blends have been investigated with the help of tapping-mode atomic force microscopy (AFM) and monitored by contact angle measurements. Chitosan is blended with polytetrahydrofuron in 1% acetic acid solution and the solution is cast to prepare the mixture film. For measurements of the contact angle liquids (glycerol) on the surface of chitosan. The surface free energy (γs), dispersive (gsd) and polar (gsp) components were calculated from contact angle values by Owens-Wendt methods using an appropriate computer program. The find values of polar and dispersive components of surface free energy show that PTHF films are much more polar than chitosan films. In case of Chitosan/PTHF blends, the values of surface free energy and polar component are decreased significantly compared with pure polymers. With the help of this behaviour it is indicated hydrophobic character of this surface. These changes of contour images were considered by determining the root mean square (RMS) deviation in the image data. This study of blends by AFM showed a totally different surface morphology when it compared with pure components. The roughness of chitosan/PTHF blends increases with the increase percentage of Chitosan content. This type of results may indicate a strong interaction between these polymeric components.
Analyzing Nonsimilar Convective Heat Transfer in Copper/Alumina Nanofluid with Magnetic Field and Thermal Radiations
Authors: Alruwaili Abdulmohsen Daham , Alruwaili Abdulmohsen Daham
Published: June 2023

Partial differential system featuring momentum and energy balance is often used to describe simulations of flow initiation and thermal shifting in boundary layers. The buoyancy force in terms of temperature is factored in the momentum balance equation. Buoyancy force causes the flow quantity to fluctuate along the streamwise direction 𝑋, therefore problem can be best analyzed through nonsimilar modeling. In this analysis nonsimilar model is evolved for radiative mixed convection of a magnetized power-law nanoliquid flow on top of a vertical plate installed in a stationary fluid. The upward linear stretching initiated the flow in vertical direction. Assuming nano-fluids are composite of copper (Cu) and alumina (Al2O3) nanoparticles, the viscous dissipation in this case is negligible. The nonsimilar system is dealt analytically by local nonsimilarity (LNS) via numerical algorithm bvp4c. Surface temperature and flow field are shown visually in relation to factors like mixed convection, magnetic field strength, nanoparticle volume fraction, radiation parameters, and Prandtl number. The repercussions of magnetic and mixed convection parameters on rate of energy transfer and friction coefficient are represented in tabular forms. The results obtained are compared to the published literature. It is found that the existence of nanoparticles significantly improves the temperature profile of considered nanoliquid. It is also observed that when the estimates of the magnetic parameter increase, the velocity profile decreases. Enhancement in nanoparticles concentration and mixed convection parameter improves the velocity profile. According to the author's findings, no published research has yet addressed the description of non-similar analysis for the considered problem. This study might be beneficial to researchers concentrating on industrial nanofluid applications.

Published: June 2023

The goal of a content delivery network (CDN) is to reduce the content delivery latency to end-users by using distributed cache servers. Nevertheless, it is very expensive to deploy and maintain cache servers in a large-scale. To solve this problem, CDN providers have come up with a new content delivery strategy: allowing end-users's IoT edge devices to share their storage/bandwidth resources. This new edge CDN platform needs to address two core questions: (1) how can we incentivize end users to share IoT devices? (2) how can we facilitate a safe and transparent content transaction environment for end users?
In this paper, we introduce SmartSharing, a new content delivery network solution. In smartSharing, the over-the-top (OTT) IoT devices belonging to end-users are used as mini-cache servers. To motivate end users to share the idle devices and storage/bandwidth resources, SmartSharing designs the content delivery schedule and the pricing scheme based on game theory and machine learning algorithms (to be specific, a tailored Expectation-Maximization (EM) algorithm). To facilitate content trading among end users, SmartSharing creates a secure and transparent transaction platform based on smart contracts in Ethereum. In addition, SmartSharing's performance evaluation not only through trace-driven simulations in the real world, but also a prototype using content metadata and the achieved pricing schemes. The evaluation results show that CDN providers, end users and content providers can all benefit from our SmartSharing framework.
Enhancing the Robustness of Block Ciphers through a Graphical S-Box Evolution Scheme for Secure Multimedia Applications
Authors: Razaq Abdul , Ahsan Muhammad Mahboob , Alolaiyan Hanan , Ahmad Musheer
Published: June 2023

Block ciphers, which serve as primary components of network security systems, play a crucial role in securely exchanging and communicating confidential information. Substitution boxes (S-boxes) are the most significant components of contemporary block ciphers. Inherently, the security strength of such cryptosystems relies on the quality of the S-box employed. The cryptographically strong S-boxes provide robustness and assurance of the security competency to block ciphers. To generate the strong S-boxes, a number of chaos-based methods have been investigated in the past decade. However, chaos-based methods are random approaches which are computationally intensive and don’t guarantee the generation of strong S-boxes. To meet the challenges of strong and fast S-box generation, a novel coset graphs based algebraic method is proposed to evolve robust and efficient S-box. Firstly, an initial S-box of decent cryptographic strength is generated by using the vertices of coset graphs for two Galois fields and a bijective function. After that, the initial S-box's robustness is improved by rearranging its columns in a particular manner, which yields the strong proposed S-box. The effectiveness of the proposed method is validated by comparing various attributes of our S-box against some recently investigated S-boxes. Additionally, the generated S-box is applied for image encryption and analyzed using the MLC criterions. The results show the suitability of the proposed S-box for secure multimedia applications.

Published: June 2023

Оценка экономичности в неустановившемся режиме, характерном для условий эксплуатации, затруднительна, поскольку нагрузочный и скоростной режимы постоянно меняются, изменяется и величина механических потерь в парах трения. В этом случае целесообразно оценивать экономичность с учетом затрат топлива и мощности на механические потери в парах трения, то есть по индикаторным показателям - удельному расходу топлива и индикаторноймощности. Величина часового расхода топлива и средней индикаторной мощности зависит от конструктивных параметров трактора, величины перевозимого груза, средней скорости движения и условий эксплуатации. Характер определяется передаточной функцией U ( s ) - динамической характеристикой частоты вращения двигателя. Гарантированные заводом-изготовителем двигателя, часовой и удельный расходы топлива, а также мощность отличаются от фактических значений при эксплуатации трактора вовсем диапазоне нагрузочных и скоростных режимов. Экспериментальные исследования различных типов двигателей с последующей аппроксимацией аналитическими выражениями амплитудно-частотных характеристик частоты вращения коленчатого вала позволили получить передаточную функцию частоты вращения, что в свою очередь дает возможность учитывать механические потери в парах трения двигателя в неустановившемся режиме при оценке экономической эффективности лесопромышленного трактора.

It is difficult to evaluate the efficiency in a non-stationary mode, which is typical for the operating conditions, as the loading and speed modes are constantly changing, and the value of mechanical losses in the friction pairs is also changing. In this case, it is advisable to evaluate the efficiency with regard to fuel and power consumption for mechanical losses in friction pairs, that is, according to indicator parameters - the specific fuel consumption and indicator power. The value of the hourly fuel consumption and the average indicator power depends on the design parameters of the tractor, the size of the transported cargo, the average speed and operating conditions. The character is determined by the transfer function U(s) - the dynamic characteristic of the engine speed. Guaranteed by the manufacturer of the engine, the hourly and specific fuel consumption and power differ from the actual values at operation of the tractor in the whole range of loading and speed modes. Experimental researches of different types of engines with the subsequent approximation by analytical expressions of amplitude-frequency characteristics of crankshaft rotation frequency have allowed to receive a transfer function of rotation frequency, which in turn gives an opportunity to consider mechanical losses in engine friction pairs in a non-stationary mode at estimation of economic efficiency of a forestry industrial tractor.
Using Radiometric Dating, Magnetostratigraphy, and Tephrostratigraphy to Calibrate Rates of Hominin Evolution in the East African Rift
Authors: Deino Alan L. , Gibert Luis , Vidal Céline M.
Published: June 2023

Age-calibration of hominin fossils and artifacts in the East African Rift is principally achieved through dating of associated volcanic-sedimentary strata. The dominant dating techniques for sites ≳100 ka are the 40Ar/39Ar radiometric dating method, magnetostratigraphy, and tephrostratigraphy. The 40Ar/39Ar technique relies on the occurrence of volcanic deposits in the target strata, which are often present as a consequence of the interplay of rift formation and volcanic activity. The frequency of datable material may be limited; however, by also applying the relative dating methods of magnetostratigraphy and tephrostratigraphy to these same strata, a chronostrati-graphic framework can be built and applied to fossiliferous strata. This chapter provides examples of the application of these techniques at Olduvai Gorge, Tanzania, and two areas of the East African Rift in Ethiopia.

Regulación y aspectos polémicos del daño punitivo en la legislación argentina
Authors: Tambussi Carlos Eduardo
Published: June 2023

El presente trabajo pretende ingresar en el estudio de la regulación del daño punitivo en la legislación de consumo de la República Argentina, con vigencia desde el año 2008. Contemplado en dos artículos de la Ley de Defensa del Consumidor 24240, la existencia misma de la figura y su técnica legislativa han generado profundas discusiones en aspectos varios relativos a su naturaleza jurídica, su extensión, sus criterios de procedencia, el modo de cuantificar la multa y el destino de los fondos en caso de obtenerse la condena. El ensayo sintetiza el análisis de la literalidad de la normativa aplicable, y el planteo de los principales problemas antes reseñados, en relación a esta figura jurídica que en el campo del derecho de usuarios y consumidores es un importante elemento a tener en cuenta a la hora de medir con qué recursos jurídicos cuentan los consumidores para lograr que mediante decisiones judiciales las prácticas abusivas de los proveedores y los grandes beneficios que muchas veces éstas importan para los dañadores, queden sin castigo o les permitan conservar el rendimiento económico de sus conductas en contra de los consumidores o de la comunidad en general.
El contractualismo de Thomas Hobbes y el derecho penal del enemigo
Authors: Espinoza Ariza Jelmut
Published: June 2023

El presente artículo explora de manera sucinta, en primer lugar, las principales ideas que giran en torno al contractualismo de Thomas Hobbes, quien es considerado como el primer filósofo político moderno, cuyo pensamiento político y social marca un corte epistemológico con la de sus predecesores al no estar fundada en el derecho divino, sino en un pacto entre seres humanos libres. La convencionalidad del lenguaje que asume Hobbes es un aporte del nominalismo; la confianza en la razón como método y como instrumento demostrativo basado en el modelo axiomático de la geometría, es propio del racionalismo de su época. En la segunda parte, entroncamos el pensamiento contractualista de Hobbes con el derecho penal del enemigo de Günther Jakobs, en el sentido de ofrecer una  justificación razonable para considerar como enemigos a aquellos delincuentes que incurren en delitos que vulneran la seguridad del Estado.

Modeling runoff management strategies under climate change scenarios using hydrological simulation in the Zarrineh River Basin, Iran
Authors: Rahvareh Maliheh , Motamedvaziri Baharak , Moghaddamnia Alireza , Moridi Ali
Published: June 2023

Lake Urmia has experienced climate change over the last decades, dramatically reducing the water level. This study applies the Soil and Water Assessment Tool (SWAT) to evaluate runoff management strategies under different climate change scenarios in the Zarrineh River Basin. We examined two runoff management strategies: the projected runoff based on the business-as-usual (BAU) trend and the Changes in Cropping Pattern (CCP). The climate variables were downscaled and projected using Climate Change Toolkit (CCT) for the near future (2025–2049) and the far future (2075–2099) periods under two Representative Concentration Pathway (RCP) scenarios (2.6 and 8.5). The results revealed that runoff decreased by 6–23 and 9–52% for the near and far future, respectively, under the BAU scenario compared to the baseline period. Antithetically, it increased by 3.5–21 and 13–55% for the near and far future periods, respectively, based on the CCP strategy estimated up to 30% higher than the BAU strategy. The ﬁndings suggested that the CCP strategy can be considered a pragmatic management strategy since the surcharged runoff collected into Lake Urmia caused the mitigation of the imminent environmental disasters in the region and provided the environmental needs of its ecosystems.

В статье рассматриваются ряд проблем, которые связаны с действующим в настоящий время подходом к криминализации и наказуемости неоконченного преступления прерванного на стадии приготовления. В результате толкования норм главы 6 Уголовного кодекса РФ, авторами затрагиваются концептуальные вопросы о наличии уголовной ответственности за приготовление к преступлению в целом, о действующем в законодательстве подходе к определению уголовной ответственности, а также о правовом содержании приготовительных действий (к преступлениям небольшой и средней тяжести) уголовная ответственность за совершение которых не наступает. На основе проведенного анализа авторы указывают на ряд неточностей в действующем в подходе к криминализации и наказуемости, приготовительных к преступлениям действий и отмечают на возможные причины их наличия. Результатом проведенного анализа является формулировка авторского подхода к регламентации приготовительных действий в уголовном законодательстве с указанием на его преимущества по сравнению с действующим в настоящее время. The article examines a number of problems that are associated with the current approach to the criminalization and punishability of an unfinished crime interrupted at the stage of preparation. As a result of the interpretation of the norms of Chapter 6 of the Criminal Code of the Russian Federation, the authors touch upon conceptual issues about the existence of criminal liability for preparing for a crime in general, about the approach to determining criminal liability that is valid in the legislation, as well as about the legal content of preparatory actions (for crimes of small and medium severity) criminal liability for the commission of which does not occur. Based on the analysis, the authors point to a number of inaccuracies in the approach to criminalization and punishability, preparing for crimes of action and note the possible reasons for their presence. The result of the analysis is the formulation of the author's approach to the regulation of preparatory actions in criminal legislation, indicating its advantages compared to the current one.

На основе анализа исторической литературы, законодательных нормативных правовых актов, а также архивных материалов автором рассмотрены вехи развития рассматриваемой меры пресечения, что позволило выделить 4 хронологических этапа. В статье указаны недостатки, возникающие в результате избрания домашнего ареста в различные исторические периоды, одновременно с этим предлагается перенять исторический опыт законодателя в части получения дополнительных ассигнований в доход государства, в случае избрания указанной меры пресечения. Результатом исследования установлено, что процесс становления мер пресечения начинался от отсутствия четкой дифференциации мер пресечения, зависимости избрания меры пресечения от решения судьи или судебного следователя, а не от нормы закона, до гуманизации норм уголовно-процессуального законодательства, строгой регламентации порядка применения мер пресечения. The article provides a retrospective analysis of the formation and development of a preventive measure in the form of house arrest, as well as the regulatory legal framework governing the procedure for its election. Based on the analysis of historical literature, legislative normative legal acts, as well as archival materials, the author considers milestones in the development of the preventive measure under consideration, which allowed us to identify 4 chronological stages. The article points out the shortcomings that arise as a result of the election of house arrest in various historical periods, at the same time it is proposed to adopt the historical experience of the legislator in terms of obtaining additional allocations to the state revenue, in case of the election of this preventive measure. The result of the study found that the process of formation of preventive measures began from the absence of a clear differentiation of preventive measures, the dependence of the election of a preventive measure on the decision of a judge or a judicial investigator, and not from the rule of law, to the humanization of the norms of criminal procedural legislation, strict regulation of the procedure for the application of preventive measures.

В статье анализируется внутренняя и внешняя структура семьи социалистического права, ее генез, преобразования в ходе исторического развития. Особое значение уделено принципам, идеям, лежавшим в основе построения социалистического права, отразившимся на ее структуре, а также исследованию изменений структуры семьи социалистического права в современных условиях. Авторы подчеркивают схожесть внутреннего строения социалистической правовой семьи с романо-германской правовой семьей, а также отмечают, что социалистическая правовая система большинства стран, ранее относившихся к социалистическому блоку, была разрушена или существенно видоизменена, после распада Советского Союза. Страны, оставшиеся на руинах социалистической правовой системы, в большинстве случаев, относят себя к романо-германской правовой семье. Сегодня семья социалистического права скорее представляет собой «подсистему» романо-германской правовой семьи, сохранив многие ее черты, терминологию и внешнюю структуру. The article analyzes the internal and external structure of the family of socialist law, its genesis, transformations in the course of historical development. Special attention is paid to the principles and ideas underlying the construction of socialist law, reflected in its structure, as well as to the study of changes in the structure of the family of socialist law in modern conditions. The authors emphasize the similarity of the internal structure of the socialist legal family with the Roman-German legal family, and also note that the socialist legal system of most countries that previously belonged to the socialist bloc was destroyed or significantly modified after the collapse of the Soviet Union. The countries left on the ruins of the socialist legal system, in most cases, refer to them-selves as the Roman-German legal family. Today, the family of socialist law is rather a "subsystem" of the Roman-German legal family, retaining many of its features, terminology and external structure.

Authors:   Alexey A. Maksurov, Yaroslavl State University named by P.G. Demidov, Maksurov Alexey A.
Published: June 2023

Статья посвящена проблемам научного «обособления», часто упоминаемой в юридической литературе, однако формально не определенной ни в доктрине, ни законодательно в категории финансово-экономических преступлений. Материалом исследования послужило российское уголовное зако-нодательство. Основным методом исследования выступает метод системного анализа. Также используются формально-логические способы и приемы. В результате исследования автором определены сущностные признаки такой группы преступлений, выделение которой имеет не столько уголовно-правовое, сколько криминологическое и криминалистическое значение. Кратко рассмотрены составы преступлений, включаемых в данную группу, с позиций их субъективных и объективных признаков. В статье подробно раскрыта проблематика выделения категории финансово-экономических преступлений. Сформулированы предложения по ее использованию в современной юриспруденции. The article is devoted to the problems of scientific "isolation" of the category of financial and economic crimes, which is often mentioned in the legal literature, but is not formally defined either in the doctrine or in the legislation. The material of the study was the Russian criminal legislation. The main research method is the method of system analysis. Formal-logical methods and techniques are also used. As a result of the study, the author identified the essential features of such a group of crimes, the allocation of which is not so much of crimi-nal law as of criminological and forensic significance. The components of the crimes included in this group are briefly considered from the standpoint of their subjective and objective features. The article reveals in detail the problems of singling out the category of financial and economic crimes. Proposals for its use in modern jurispru-dence are formulated.
Impact of GDP growth on the ecological footprint: Theoretical and empirical evidence from Saudi Arabia
Authors: Alruweili Faris
Published: June 2023

This study aims to examine the hypothesis of the environmental Kuznets curve (EKC) within the context of Saudi Arabia from 1981 to 2017. The ARDL approach is employed to estimate the relationship between ecological footprint, energy consumption, trade openness, and GDP per capita. The findings confirm that GDP per capita, trade openness, and energy consumption positively impact the ecological footprint, and reveal the presence of a feedback relationship between GDP per capita and energy consumption. The results demonstrate the empirical validity of the EKC, indicating an inverted U-shaped relationship between GDP and ecological footprint. Consequently, as Saudi Arabia's level of economic growth advances, its environmental conditions tend to improve. To further reduce the ecological footprint, Saudi Arabia is urged to substantially increase its utilization of renewable energy sources and implement a more efficient energy policy.

Ipomoea batatas L. is one of the crops that has greater importance in the world for its high content of dietary fiber, vitamins and antioxidant compounds; and it is widely known for its consumption in more than 100 countries (García-Méndez et al., 2016). In addition being a source for industrial production of flour, starch and alcohol, the sweet potato is a rustic species, which has great resistance to pets and diseases and is adapted to various tropical areas (Reina,2015). Its rusticity also implies the requirement of lower doses of fertilizers, such as N and P, and lower quantity of pesticides. The sweet potato is considered one f the most efficient species in the use of water; so it could be grown on soils with marginal agricultural value (La Rosa,2008).

Published: June 2023

BACKGROUND

The goal of public health is to improve the health of populations. To accomplish this, data is needed to support decision-making. These data are typically obtained through self-report methods that may be subject to biases, costs and delays. In this context, objective data from sensors embedded in personal smart devices present itself as potential alternative measurement tools.

OBJECTIVE

The goal of this work is to describe the modelling and development a mobile health platform (MHP) that collects health data from the Apple Health repository, to be used as a tool for real-world data collection.

METHODS

The MHP was developed using Apple’s XCode software and the Swift programming language based on a real-world pilot study protocol involving stress-related health data from Apple Health.

RESULTS

The MHP interface, modelling and architecture is detailed, including the UML diagram, app flow, and health data type structures. Future directions for new versions of the MHP are also presented.

CONCLUSIONS

A similar system to the MHP could be used for public health surveillance, complementing traditional self-report metrics when applicable. Researchers and public health specialists must respect applicable security and privacy regulations when collecting digital health data.
