A Review of Individual Level Knowledge Sharing in the Workplace
Authors: Nasirova Gulnora , Soatova Gulsunoy , Tilovova Gavhar , Makhim Artikova
Published: December 2023

This paper explores individual-level knowledge sharing. Knowledge sharing is a key organizational citizenship behaviour that contributes to an organization’s innovation and competitiveness and as such has received much attention from the research community. However, most of the studies which reviewed the area of knowledge sharing did so by combining organizational, team and individual level factors. As knowledge sharing is conducive to building collective intelligence and improving work performance the way it is approached should be more refined. The study explores the individual-level knowledge sharing focusing only on individual characteristics. Factors such interpersonal trust and justice, individual attitudes towards knowledge sharing, personality traits, cultural aspects, motivational factors, beliefs about knowledge ownership and perceived benefits and costs, are examined to understand their relationship with knowledge-sharing behaviour. Based on the detailed review future research directions are proposed. Deeper investigation is warranted on the personality traits, motivational theories, emotional intelligence, learning styles, mental well-being, cultural nuances, and neuroscientific perspectives in knowledge sharing.
Postmodernizm i ponowoczesność w świetle rozwoju technologii cyfrowych i procesu indywidualizacji
Authors: Pieniążek Paweł
Published: December 2023

Celem artykułu jest skonfrontowanie postmodernizmu rozumianego jako doktryna filozoficzna, czy, szerzej, pewien typ świadomości kulturowej z ponowoczesnością jako epoką stanowiącą wyraz przemian późnego kapitalizmu. Związki między postmodernizmem I ponowoczesnością analizowane są w perspektywie filozoficzno-socjologicznej poprzez porównanie diagnoz ponowoczesnych przemian przedstawionych przez przedstawicieli postmodernizmu i diagnoz przedstawionych przez socjologów ponowoczesności. W pierwszej części omawiam znaczenie technologii cyfrowych, w których postmoderniści pokładali nadzieję na wyzwolenie potencjału ludzkiej kreatywności, w drugim ponowoczesne procesy indywidualizacji związane z ideą samorealizacji. W konkluzji dochodzę do przekonania, że ponowoczesność sprzeniewierzyła się głoszonym przez postmodernizm ideom wolności, kreatywności, samorealizacji, solidarności. 

W konkluzji wyrażam przekonanie, że ponowoczesność sprzeniewierzyła się ideom wolności, kreatywności, samorealizacji, solidarności głoszonym przez postmodernistów, które zgodnie z ich nadzieją miała ona urzeczywistnić.
Elaboration sites and prepositional meaning construction in English and Polish
Authors: Brenda Maria
Published: December 2023

Although prepositions are relational linguistic units of modest sizes, they can contribute a variety of different meanings to the constructions they are found in. The paper looks into the notion of e-site, which allows for conceptual elaboration of more schematic entities along the vertical and horizontal dimensions of the human conceptual representation. It argues that e-sites are useful for prepositional meaning description. First, e-sites come into play when schematic TRs and LMs of the preposition are elaborated by more specific conceptual structures, thereby, forming a vertical schematic-specific hierarchy of conceptual structures. Along the horizontal dimension, e-sites are responsible for the integration of the conceptual content of expressions which come together to form constructions. This type of elaboration finds its expression in the typology of languages (satellite- or verb-framed) proposed by Talmy (2000) and elaborated by Slobin (2005).
Language Proficiency and Sonorant Devoicing in English Plosive-Sonorant Clusters
Authors: Přečková Klára , Šturm Pavel , Volín Jan
Published: December 2023

This article explores the timing of phonetic voicing in plosive-sonorant clusters in English. VOT was measured in two groups of Czech learners with different proficiency levels and a native English control group. The hypothesis was that cross-language differences in the implementation of the voicing contrast would be reflected in lower devoicing by the non-native speakers, modulated by proficiency. 24 participants read a text with plosive-sonorant clusters (such as in plan or troops). The study found that less proficient speakers exhibited smaller degrees of devoicing compared to more proficient speakers, who however did not differ from the native controls. In line with the absence of devoicing in Czech secondary-school textbooks, the results provide insight into the interplay between language proficiency and pronunciation details in L2 acquisition.

Aplicación de yeso sobre un suelo con alta concentración de sodio de origen natural
Authors: Ballestero Johana , Barbazán Monica , Del Pino Amabelia
Published: December 2023

Los suelos con exceso de sodio de origen natural aumentan la concentración de Na intercambiable con la profundidad. Son suelos improductivos por la pérdida de la macroporosidad y por el efecto negativo en el metabolismo de las plantas. El yeso mejora las propiedades de estos suelos al desplazar al Na en exceso por Ca. Para evaluar el efecto del yeso sobre un suelo con exceso de Na de origen natural con pastura implantada (Festuca arundinacea), se instalaron dos experimentos contiguos de parcelas dispuestas al azar: Experimento 1, cuatro dosis (1, 2, 3, 0 Mg ha-1) de dos yesos; y Experimento 2, tres dosis (0, 0.6 Mg ha-1 de azufre, 3 Mg ha-1 de tres yesos). Luego de 420 días, en las parcelas del Experimento 1 donde se aplicó la enmienda, el Na intercambiable se redujo un 22 % con un aumento paralelo del 10 % de Ca intercambiable, presentando mayor penetrabilidad y humedad del suelo y alrededor de 50 % mayor rendimiento de la pastura. En tanto, que en el Experimento 2 hubo rendimientos similares para las enmiendas, aunque la absorción de azufre fue 5 % mayor por las pasturas con yeso. Se concluye que el yeso agrícola es efectivo para disminuir el Na intercambiable en la profundidad de suelo estudiada, aumentar el rendimiento y mejorar la calidad de la pastura. Dado que la fuente natural del Na no puede ser aislada debe estudiarse a largo plazo la efectividad de las dosis y las fuentes de yeso.
Coronaphobia – What Do Coronaphobia Scales Measure? An Analysis of 12 Open Instruments and their Correlates
Authors: Radević Luna , Milošević Marko , Milosavljević Miroslav , Dinić Bojana
Published: December 2023

Previous studies confirmed the psychological, psychosomatic, and economic consequences of the COVID-19 outbreak, which lead to the introduction of a new concept of coronaphobia as a persistent and excessive fear of the novel coronavirus. With the beginning of the pandemic, the interest in coronaphobia-related measurement began and until 2021, 12 instruments were created, with a total of 28 (sub)scales. The first aim of this study was to explore the joined factor structure of these measurements. The second aim was to explore a wide range of correlates of coronaphobia (sociodemographic characteristics, general anxiety disorder, Big Five traits, knowledge about coronavirus, and political orientation). The sample included 347 participants (42.1% male) from the general population of Serbia and data were collected in April 2021. Results showed that only one component could be extracted based on 28 (sub)scales of coronaphobia, meaning that physiological, cognitive, emotional, and behavioral aspects of coronaphobia are rather intercorrelated. Furthermore, among explored correlates, general anxiety disorder had the highest contribution to the explanation of coronaphobia. Additionally, Openness showed a negative, and age showed a positive contribution to the explanation of coronaphobia. Our results suggest that coronaphobia should be understood as a syndrome that captures physiological, cognitive, behavioral, and emotional aspects, and that individuals who are already prone to anxiety disorders are more prone to coronaphobia as well.

General approaches to their solution and possible options for further actions are proposed, depending on the complexity of the socio-economic and demographic situation.
Local groups of the Russian ethnos at the end of the XIX-first quarter of the XX centuries : historical and demographic research
Authors: Kropachev S.
Published: December 2023

The paper deals with ethnic groups of the Russians of the late XIX- first quarter of the XX centuries. The author divides all local groups of the Russians into ethno-territorial, ethno-class, ethno-confessional and ethnographic ones. They were formed in the context of the development of territorial-economic and historical-cultural clusters: Southern and Central Russian, North Russian, Siberian, Far Eastern and Central Asian. Subethnic groups of the Russians had to adapt to different climatic conditions, perceive the way of life and a new type of economy, elements of the material culture of the aboriginal peoples. The degree of closeness to indigenous peoples varied. From self-isolation to close contacts and mixed marriages. At the same time, as a rule, the Russians retained their language, cultural elements, ethnic identity and other basic values. The paper presents demographic indicators of local groups of the Russians of the late XIX-first quarter of the XX centuries.
Special (labor) settlements as populated areas in the 1930s (based on materials of the Komi Republic)
Authors: Ignatova N.
Published: December 2023

In 1930-1931 in the Komi Autonomous Region, special settlements were organized for special settlers – “former kulaks” who were forcibly expelled from their places of permanent residence from areas of complete collectivization. Able-bodied forced migrants and members of their families were transferred to the Komiles Trust to work in logging. In the logging areas of the region, more than 40 special settlements were organized in hard-to-reach places, isolated from local settlements. Problems associated with the lack of roads, remoteness from regional centers, insufficient supplies, and the organization of settlements in swampy areas led to the liquidation of individual special (labor) settlements and a reduction in their total number by the end of the 1930s. Despite the low level of residential premises construction, forced migrants also built buildings for socio-cultural institutions, schools, hospitals, clubs and others, which made it possible to create the internal infrastructure of the settlements.

Published: December 2023

Understanding the dynamic evolution of zeolite framework structures and the interactions between various hydroxyl groups or aluminum species under different steam conditions at the atomic scale is extremely crucial. Herein, using a series of characterization methods, the framework structures of HZSM-5 zeolites (Si/Al = 36) following exposure to steam in the temperature range of 100 to 500 °C are investigated. Under mild steam conditions (T ≤ 200 °C), dealumination is nearly absent, and the silanol nests directly condense to create new framework Si-O-Si bonds. Conversely, under severe steam conditions (T ≥ 300 °C), the framework tetrahedral aluminum atoms Al(IV)-1 can be sequentially converted to partially coordinated framework aluminum Al(IV)-2 and extra-framework aluminum (EFAL) through partial and complete hydrolysis, which cause an increase in the framework Si/Al ratio and a decrease in crystallinity. Al(IV)-2 is recognized as a significant intermediate species for framework complete dealumination. The Brønsted acid sites on Al(IV)-2 can be perturbed by the framework Al-OH groups due to hydrogen bonding interactions, leading to a shift in 1H chemical shifts to lower fields, appearing at 6.0-9.0 ppm and 12.0-15.0 ppm. The newly generated EFAL and silanol nests further evolve through condensation as well. Meanwhile, during dealumination, the spatial correlations (or interactions) of various hydroxyl groups on structurally distinct aluminum species [Al(IV)-1, Al(IV)-2, and EFAL] and aluminum species become extremely intricate. Based on these findings, the dynamic evolution path of HZSM-5 zeolite framework structures under mild and severe steam conditions is proposed.
METHOD OF AUTOMATED DETERMINATION OF EARLY SIGNS OF PULMONARY HYPERTENSION
Authors: Klotchko Tatiana , Yakobchuk Eugene
Published: December 2023

An urgent problem of modern diagnostic methods of medicine is the development of non-invasive methods that use information signal processing systems from the biological object of research. An expedient technical solution to such problems is the use of artificial intelligence in systems and complexes that combine diagnostic functions based on the parameters of the patient's physiological condition.The consequences of the development of physiological pathologies in the human body, such as pathologies of the cardiovascular system, are the possibility of the occurrence of pulmonary hypertension and its varieties, which depend on the characteristics of the hemodynamics of the small blood circulation, increasing the pressure in the pulmonary blood circulation. These features of the disease can lead to the development of pulmonary arterial hypertension. It is proposed to implement the method of applying the feedback chain. Thus, the feedback principle makes it possible to implement a program that calculates the measured values of the parameters of the patient's functional state, and then compares them with the limit values of these parameters to obtain a final conclusion and provide results simultaneously to the doctor and the user. From the obtained results, it can be seen that the time of obtaining preliminary diagnostic results according to the proposed implementation scheme of the method is ten times faster under the condition of using the feedback method than with traditionally applied methods. The main criteria for the reliability and speed of the work of determining critical situations with the help of developed algorithms for the implementation of the methodology for determining the early signs of pulmonary hypertension and its consequences are proposed. It is important to note that despite the fact that the results are obtained extremely quickly, the final diagnosis is made by the doctor based on his own observations and analysis of the patient's current condition. Algorithms for the implementation of the method are proposed, whichapply the principles of operation of a portable complex based on a monitor to obtain continuous characteristics of the patient's condition and transmit them in the mode of using the principles of telemedicine to determine the diagnosis.The principles of the functioning of automated diagnostic systems, which are intended for monitoring, obtained in the work can be the basis for the further creation of new methods and improvement of automated diagnostic systems and the identification of early signs of violations of the patient's functional state of the diagnostic tools.
Research on the Dynamic Range of Silicon Photodiodes for Optical Pyrometry Applications
Authors: Verbitskyi Dmytro O. , Voronko Andryi O.
Published: December 2023

Optical pyrometry is one of the main non-contact methods for precise temperature measurement of semiconductor wafers for vapour-phase epitaxy from metal-organic compounds (MOCVD). The requirements for the photocell of the pyrometer are due to the peculiarity of the process. In the pyrometer, the silicon photodiode operates in a mode that is characterized by a small bias voltage value, high sensitivity to weak light radiation, and low noise level. The main temperatures used in vapour-phase epitaxy technology depend on the semiconductor material being grown and the process parameters. Typically, process temperatures range from 500 to 1200 °C. A study of the dynamic range of a silicon photodiode for use in optical pyrometry was conducted. It was established that the minimum value of the dark current and the maximum value of the spectral sensitivity are key to obtaining the desired characteristics, namely, sensitivity to thermal radiation at a temperature of 450 °C. The peculiarities of the manufacturing technology of the planar-diffusion structure of the photodiode to achieve the necessary characteristics that ensure the production of photodiode structures with improved parameters are also considered.
Human Eye Aberrometry Data Generation Using Generative Adversarial Neural Network
Authors: Yaroshenko Maksym Oleksandrovych
Published: December 2023

It’s obvious that for development and improvement of methods and apparatus for diagnosis and treatment of optical flaws of human eye at the modelling stage, it’s necessary to have sets of real measurements. However, data requests to clinics are accompanied by substantial amount of bureaucracy procedures and, at the same time, acquired dataset may be too small, which can be critical, for example, for training of neural networks. According to the analysis of existing publications, publicly available datasets of aberrometry data (sets of eye’s refractive flaws) are rare and consist of relatively low number of measurements. But, due to current development state of neural networks, it is possible to generate data based on real measurements. The most common solutions are methods based on the usage of the Generative Adversarial Networks (GAN). This tendency is also relevant for the modern ophthalmology, but no publications aimed at aberrometry data synthesis were found. For this reason, objective of this work is development of solution for generation of sets of human eye’s refractive errors using neural networks. Proposed solution includes generator and critic networks trained according to the Wasserstein GAN with Gradient Penalty (WGAN GP) algorithm. In order to improve training, the method of data augmentation called Data Augmentation Optimized for GAN (DAG) was used, moreover, the possibility of augmentation of aberrometry data in two forms was implemented — for both Zernike coefficient vectors and wavefront pixel images. According to the result’s evaluation, generated data has the distribution close to the real sample (Fréchet distance equals 0.7) and, at the same time, it is neither a copy of real measurements (92% creativity rate) nor duplication of a few aberration sets (diversity metric equals 3.64 which is close to the optimal 3.83). The direction of further improvement includes enhancement of existing architectures of generator and critic, search or creation of bigger training dataset and refinement of data augmentation technics.
ALTERAÇÕES NOS PARÂMETROS SANGUÍNEOS E MORFOFISIOLÓGICO HEPÁTICO EM TILÁPIA-DO-NILO, OREOCHROMIS NILOTICUS, APÓS EXPOSIÇÃO AGUDA COM BIOINSETICIDA A BASE DE BACILLUS THURINGIENSIS

Published: December 2023

Os biopesticidas visam substituir pesticidas sintéticos, sendo que, os formulados a base de Bacillus thuringiensis (Bt) os mais empregados nas lavouras. Todavia, é pouco conhecido o seu mecanismo de ação e efeitos sob a biota aquática. O objetivo foi avaliar os efeitos subletais do Bt em tilápia-do-Nilo após exposição aguda. Os peixes foram divididos em um grupo controle (GC), um exposto à 30 mg L-1 do biopesticida (G30) e um exposto a 40 mg L-1 do Bt (G40), por 48 horas. Após exposição, amostras de sangue e fígado foram coletadas para análise de toxicidade. O número de eritrócitos com núcleos lobulados e reniformes aumentou, mas sem observância de micronúcleos. Não houve alteração nos parâmetros eritrocitários, todavia, o número de leucócitos totais e trombócitos aumentou nos tratados.  Alterações histopatológicas hepáticas foram evidenciadas por um aumento de inclusões intracelulares, alteração nucleares e diminuição de hepatócitos hipertrofiados entre os tratados. O Iorg demostrou comprometimento do tecido hepático no grupo G30 em relação ao controle e entre tratados. Os danos resultantes da exposição ao Bt podem ser severos, mesmos sendo categorizados como reversíveis. Concentrações baixas de Bt podem induzir efeitos deletérios para peixes, interferir no sistema imune e citológico do sangue e fígado.

Published: December 2023

As cascas e sementes de abóbora apresentam potencial nutricional e funcional, podendo ser indicadas para a indústria de alimentos. Objetivou-se elaborar e avaliar as características bromatológicas e microbiológicas de farinhas de casca (FCA) e semente de abóbora (FSA) para posterior aplicação em panificação. As abóboras foram higienizadas, descascadas e suas sementes retiradas. As cascas e sementes foram secas em estufa, trituradas e peneiradas para a obtenção das farinhas. Os resultados demostraram maiores teores de umidade, cinzas, fibras alimentares e carboidratos na FCA, enquanto maiores teores de proteína, gorduras e valor energético foram obtidos na FSA. Quanto a coloração, ambas as farinhas, apresentaram-se claras, com baixa pureza de cor e tonalidade amarela. Os valores de umidade, Aw e pH foram adequados para garantir a estabilidade microbiológica das farinhas, tornando-as seguras para a alimentação humana. A FCA e FSA apresentaram teores de fenólicos, flavonoides e atividade oxidante com potencial funcional para prevenir e reduzir riscos de desenvolver doenças crônicas não transmissíveis. Conclui-se que a inclusão de FCA e FSA em produtos de panificação é uma opção para enriquecer as preparações com nutrientes funcionais e compostos bioativos com benefícios à saúde.

Authors: Alneyadi Shaikha , Alhassani Mohammed , Aleissaee Ali , Al Mujaini Ibrahim
Published: December 2023

Abstract: The expansion of global industries results in the release of harmful volatile acid vapors into the environment, posing a threat to various life forms. Hence, it's crucial to prioritize the development of swift sensing systems capable of monitoring these volatile acid vapors. This initiative holds great importance in safeguarding a clean and safe environment. This paper presents the synthesis and characterization of pyrene-based covalent organic frameworks (COFs) demonstrating exceptional crystallinity, thermal stability, and intense fluorescence. Three COFs—PP-COF, PT-COF, and PE-COF—were synthesized, showcasing large surface areas and robust thermal stability up to 400 °C. The fluorescence properties and intramolecular charge transfer within these COFs were significantly influenced by their Schiff base bonding types and π-stacking degrees between COF layers. Notably, PE-COF emerged as the most fluorescent among the three COFs and exhibited exceptional sensitivity and rapid response as a fluorescent chemosensor for detecting HCl in solution. The reversible protonation of imine bonds in these COFs allowed for the creation of highly sensitive acid vapor sensors, showcasing a shift in spectral absorption while maintaining structural integrity. This research highlights the potential of COFs as reliable and reusable sensors for detecting harmful acid vapors, addressing environmental concerns arising from industrial activities.
Homing and Engraftment of Hematopoietic Stem Cells Following Transplantation:
A Pre-clinical Perspective
Authors: Hasan Tanvir , Pasala Ajay Ratan , Hassan Dhuha , Hanotaux Justine , Allan David S , Maganti Harinad B
Published: December 2023

Hematopoietic stem cell (HSC) transplantation (HSCT) is used to treat various hematologic disorders. Use of genetically modified mouse models of hematopoietic cell transplantation have been critical in our fundamental understanding of HSC biology and developing approaches for human patients. Pre-clinical studies in animal models provide insight into the journey of transplanted HSCs from infusion to engraftment in bone marrow (BM) niches. Various signaling molecules and growth factors secreted by HSCs and the niche microenvironment play critical roles in homing and engraftment of the transplanted cells. The sustained equilibrium of these chemical and biologic factors ensures that engrafted HSCs generate healthy and durable hematopoiesis. Transplanted healthy HSCs compete with residual host cells to repopulate stem cell niches in the marrow. Stem cell niches, in particular, can be altered by the effects of previous treatments, aging, and paracrine effects of leukemic cells that create inhospitable bone marrow niches that are unfavorable for healthy hematopoiesis. More work to understand how stem cell niches can be restored to favour normal hematopoieis may be key to reducing leukemic relapses following transplant.

Authors: Utami Niken Subekti Budi , Sudiarsana I Kadek
Published: December 2023

The death penalty, one of the punishment types regulated in the Indonesian Criminal Code, continues to be imposed despite conflicts between abolitionists and retentionists. The existence of the death penalty in Indonesia has a legal consequence, which is the need for legal certainty regarding the status of death convicts, who are often entrusted to a Correctional Facility during the waiting period for execution. The enactment of Law Number 22 of 2022 classifying death row inmates as prisoners, along with their rights and obligations. This research uses legal research supported by data from interviews with experts. Data obtained from literature research was analyzed descriptive-qualitatively. The result showed that death row inmates must participate in coaching programs like other prisoners. The coaching program was divided into two parts: character and independence coaching. From the aspect of practicality, character coaching is more beneficial for death row inmates compared to independence coaching, as death row inmates would not return to society and would be waiting for their execution time unless their clemency request was granted. 
Traceability ensuring by organizing the Metrological Measurements Network
Authors: Samoilenko Oleksandr , Tsiporenko Sergii
Published: December 2023

A new scheme for the traceability ensuring, called the Metrological Measurements Network, was proposed. It is not an alternative to the existing scheme but is only another form of implementation of the traceability scheme. It is about the main principle of construction of the Metrological Measurements Network and its advantages over the existing scheme. The main reason is that each laboratory calibrates its own object for measurement using its measurement standard and sends it for calibration to a laboratory-participant and, almost simultaneously, receives a similar object from another laboratory-participant that calibrated it. If each participant, at the same time as the others, makes at least four such calibrations and transfers between laboratories-participants, it will form a common and very precise Metrological Measurement Network in a very short time. It can cover hundreds and even thousands of laboratories in a short period of time. The joint processing of a large number of such measurements will help to define the additive and/or multiplicative biases of each measurement standards. Moreover, the reference conditions are imposed that the sum of additive and, separately, the sum of multiplicative biases for all measurement standards is equal to zero regardless of the number of network participants.
A methodological approach towards the bio-inspired design of novel scaffolds for tissue engineering
Authors: Fucile Pierpaolo , Lamonaca Francesco , Gloria Antonio , Moroni Lorenzo
Published: December 2023

The design of scaffolds for multi-tissue regeneration is very complex in terms of material and structure, as a direct consequence of hierarchical and organizational features. TRIZ represents the Russian acronym for the “Theory of Inventive Problem Solving” (TIPS). TRIZ is able to identify and codify such principles, using them to make the creative process more predictable. It is a methodology for the identification of the system conflicts and contradictions in order to solve the inventive problems. Its multidisciplinary features and the general approach to product design can make TRIZ as an intriguing starting point for the biomimetic approach in a systematic and organized way. Biomimetics aims at a complete integration between nature and technology. In this scenario, BioTRIZ shares the contradiction resolution method of the Altshuller’s theory, representing a systematic biomimetic approach towards the product design. In the current study, BioTRIZ was considered to systematize the process of bio-inspired design of 3D optimized scaffolds for the regeneration of complex tissue defects. A device for the regeneration of osteochondral tissue defects was considered as a case study. The technical solutions involved the design of a two-compartment, hybrid and functionally graded scaffold.

Islamic Sharia stipulates that marriages must be announced to the public. One method of the announcement is through walīmat al-‘urs, translated differently in different Muslim communities. In the city of Solok, West Sumatra, one of the forms of walīmat al-‘urs is the baarak bako tradition (a wedding parade around the village). Baarak bako's implementation frequently clashes with obligatory prayer times in Islam, causing many participants to leave the prayer. This research aims to examine the background of the baarak bako tradition, the reasons for deciding the time to perform baarak bako, and the effects of baarak bako on prayer services. Using a qualitative method, this article revealed that the origin of baarak bako was the desire of the bako (father's female family) to show their presence by enlivening anak pisang's (the children of a brother) wedding. According to the custom, the best time to announce a marriage is in the afternoon because people are already at home and have finished their activities outside the home; the implementation of baarak bako resulted in some participants failing to perform the obligatory prayers. The neglected prayers are carried out in jama' (merging two prayers). Others, on the other hand, leave the prayer without jama'. The people of Solok City are very rigorous about following customary rules. When religious law and customary law rules conflict, some people prefer customary rules over religious rules and vice versa. These findings show the dynamic relationship between religion and customs in the Minangkabau ethnic group, West Sumatra. These two norms can coexist and adapt to each other in practice.

Widows’ Rights and Customary Law: Addressing Responsive Law to Divorce Cases of Tolaki Community in Indonesia
Authors: Kamaruddin Kamaruddin
Published: December 2023

This article discusses the tendency to ignore women's rights in customary law practices in the Tolaki tradition, Southeast Sulawesi, Indonesia. Women often become a victim of deprivation of rights by customary legal tradition, such as ex-wife rights in post-divorce and the right to make choices. This article aims to discuss how widows are protected by custom by offering responsive law as a process for resolving marriage and divorce through customary decisions. Normatively, legal divorce settlements can only be processed through religious court institutions. Using a normative-empirical approach, this study has three significant findings. First, the process of resolving family conflicts involves complying with applicable customary provisions that must be obeyed by the Tolaki community. Second, tradition is not the only basis for consideration in the elements for making customary decisions. Third, responsive law can theoretically direct the lives of the people of the Tolaki traditional community by providing recommendations for considerations that are in accordance with the social structure and community relations related to the application of customary law. However, according to custom, widows who are not resolved before a court hearing can be followed up again to immediately register their case in a religious court in order to minimize neglect of the right to terminate a unilateral divorce and the rights of the widow and children after divorce. Under these conditions, offering responsive law is a strategy to balance rights in divorce cases bound by state legal norms.

Published: December 2023

The helical-axial multiphase mixed-transport pump fails due to gas blocking caused by gas-liquid separation caused by cavitation under complex conditions with high gas volume fraction. This is an urgent engineering problem that needs to be addressed in the application of this pump. In order to simulate the flow structure characteristics in the channel, two types of non-uniform inflow boundary conditions are introduced. The bubble structure, velocity, and pressure of the inflow conditions under different operating conditions are compared and analyzed, and the variation rules affected by the non-uniform boundary conditions are obtained. At the same time, the internal flow characteristics and mechanisms of helical-axial multiphase mixed-transport pumps are analyzed based on the velocity changes at the inlet of the impeller and the pressure fluctuations at the outlet of the diffuser, leading to the intensification of gas-liquid separation and eventually the development of gas blocking. Research has shown that through programmatic control of the inlet boundary conditions, a linear change in inlet pressure has a more significant effect on the intensification of gas-liquid separation in the flow channel of the mixed transport pump than a sinusoidal change, ultimately leading to significant performance failure when generating gas blocking. The research conclusion provides reference value for solving gas blocking in engineering applications of helical-axial multiphase mixed-transport pump.

Background: T cells play a crucial role in the development of systemic lupus erythematosus(SLE), and their function is mediated by various metabolic pathways and enzyme activities. Here, we aim to analyze the phenotype of glucose metabolism of peripheral blood CD4+ T cells. Also, the effects of human umbilical cord-derived mesenchymal stem cells (hUC-MSCs) on the proliferation, function, and glucose metabolism of peripheral blood CD4+ T cells in SLE patients were assessed to elucidate the pathogenesis of SLE and the therapeutic mechanism of hUC-MSCs based on metabolic reprogramming.
Methods: The clinical data and peripheral blood of 15 SLE patients and healthy controls were collected. CD4+ T cells were isolated via immunomagnetic beads followed by activation in presence of anti-CD3/CD28 in vitro. After 72h co-culture of with hUC-MSCs, CD4+ T cell viability was detected by CCK-8 assay. The Seahorse Bioscience XFe24 Extracellular Flux Analyzer was used to measure the oxygen consumption rate(OCR) and glycolytic proton efflux rate(glycoPER) of CD4+ T cells. Multiplex cytokine assay was conducted to detect the cytokines in the supernatant. The expression of genes was determined and identified by transcriptome sequencing.
Results: Compared to the healthy controls, the OCR and glycoPER levels of activated CD4+ T cells were greatly increased in SLE (P<0.05). After 72h co-culture with hUC-MSCs, the OCR, glycoPER, cell viability and proinflammatory factors of SLE-CD4+ T cells decreased considerably(P<0.01). The mRNA levels of 434 genes were upregulated, and 172 genes were downregulated; this phenomenon was pronounced in the JAK-STAT and PI3K-Akt pathways.
Conclusion: The levels of oxidative phosphorylation and glycolysis of CD4+ T cells were considerably increased in SLE patients, indicating that the glucose metabolism phenotype of CD4+ T cells, a potential therapeutic target, was closely related to the pathogenesis of the disease. hUC-MSCs reduced the proliferation activity of SLE-CD4+ T cells, altered the phenotype of glucose metabolism, reduced the level of proinflammatory factors, and increased the level of anti-inflammatory factors. The regulatory effects of MSC on the cellular energy metabolism phenotype may be related to the influence of JAK-STAT and PI3K-Akt signaling pathways.
Altimetry-based ice-marginal lake water level changes in Greenland: Unveiling annual variations in glacial lake outburst floods linked to runoff

Published: December 2023

Greenland holds more than 3300 ice-marginal lakes, serving as natural reservoirs for outflow of meltwater to the ocean. A sudden release of water can largely influence ecosystems, landscape morphology, ice dynamics and cause flood hazards. While large-scale studies of glacial lake outburst floods (GLOFs) have been conducted in many glaciated regions, Greenland remains understudied. Here we use altimetry data to provide the first-ever Greenland-wide inventory of ice-marginal lake water level changes, studying over 1100 lakes from 2003–2023, revealing a diverse range of lake behaviors. Around 60% of the lakes exhibit minimal fluctuations, while 326 lakes are actively draining, collectively contributing to 541 observed GLOFs from 2008–2022. These GLOFs vary significantly in magnitude and frequency, with the highest concentration observed in the North and North East regions. Our results show substantial annual differences in the number of GLOFs and the variations are driven by annual difference in meltwater runoff, except for the South West region. Our method detected a 1200% increase in the number of draining lakes compared to existing historical databases. This highlights a significant underreporting of GLOF events and emphasizes the pressing need for a deeper understanding of the mechanisms behind and the consequences of these dramatic events.
HPGD: an intermediate player in microglial polarization and multiple sclerosis regulated by Nr4a1

Published: December 2023

Introduction
HPGD encodes 15-Hydroxyprostaglandin dehydrogenase catalyzing the decomposition of prostaglandin E2 and has not been reported in multiple sclerosis (MS). We previously found that Nr4a1 regulated microglia polarization and inhibited the progression of experimental autoimmune encephalomyelitis (EAE). Bioinformatics analysis suggested that HPGD might be regulated by Nr4a1. Therefore, this study aimed to explore the role of HPGD in microglia polarization and determine whether HPGD mediates the inhibition of EAE by Nr4a1.
Methods
C57BL/6 mice were treated with MOG35-55 peptide to induce EAE. BV-2 cells were treated with LPS/IL-4 to induce M1/M2 polarization. We then analyzed the pathological changes of spinal cord tissue, detected the expression levels of M1/M2 genes in tissues and cells, and explored the effect of HPGD on PPARγ activation to clarify the role of HPGD in EAE. The interaction between HPGD and Nr4a1 was verified by ChIP and pull-down assay.
Results
HPGD was downregulated in the spinal cord of EAE mice and HPGD overexpression alleviated the progression of EAE. Experiments in vitro and in vivo revealed that HPGD inhibited M1 polarization, promoted M2 polarization and increased PPARγ-DNA complex level. Nr4a1 could bind to the promoter of HPGD and its overexpression increased HPGD level. HPGD overexpression (or knockdown) reversed the effect of Nr4a1 knockdown (or overexpression) on M1/2 polarization.
Conclusion
HPGD is regulated by Nr4a1 and inhibits the progression of EAE through shifting the M1/M2 polarization and promoting the activation of PPARγ signaling pathway. This study provides potential targets and basis for the development of MS therapeutic drugs.
