Association Between Cold Hypersensitivity in the Extremities and Functional Dyspepsia: Insights from a Multicenter Survey Study
Authors: Adamopoulos Ioannis
Published: January 2025

The study examined the effects of cold hypersensitivity in hands and feet (CHHF) on the symptoms of functional dyspepsia. A study utilizing survey methods yielded completion from 6044 individuals to determine their Hand and Foot Cold Hypersensitivity status along with their dyspepsia symptomatology. Based on their responses, participants were divided into two groups: A group assigned as CHHF comprised of 1,209 participants felt cold sensations while the remaining 1,744 participants made up a non-CHHF comparison group who experienced warm or neutral sensations. Statistical evaluation of digestive symptom frequencies occurred through chi-square tests and logistic regression methods to generate outcome ratios (ORs) and create propensity scores between the two participant groups. Dyspeptic symptoms such as poor digestion and reduced appetite and upper abdominal discomfort and motion sickness and epigastric burning and postprandial fullness and nausea and bloating were significantly more frequent among participants from the CHHF group. Participants within the CHHF group showed a statistically higher occurrence of dyspeptic symptoms with vomiting and epigastric pain alongside various gastrointestinal problems compared to controls without CHHF. The findings highlight a potential association between CHHF and a higher prevalence of functional dyspepsia symptoms. In conclusion, this study provides evidence that individuals with cold hypersensitivity in the hands and feet are more likely to experience various symptoms of functional dyspepsia. These results underscore the need for further investigation into the underlying mechanisms linking CHHF and dyspepsia, which may have implications for targeted clinical interventions and management strategies for affected individuals.

ОСОБЛИВОСТІ РЕГУЛЮВАННЯ ДОГОВІРНИХ ВІДНОСИН В УКРАЇНІ ПІД ЧАС ВОЄННОГО СТАНУ
Authors: Духневич Андрій , Лук’яненко Сергій
Published: January 2025

Стаття присвячена особливостям правового регулювання договірних відносин в Україні під час воєнного стану. У контексті воєнних дій, які значно впливають на економічну, правову та соціальну сфери, дослідження цього питання є актуальним для забезпечення стабільності договірних зобов’язань, мінімізації ризиків для сторін договорів і адаптації нормативної бази до умов кризи. Мета дослідження полягає у виявленні змін та особливостей регулювання договірних відносин у період воєнного стану в Україні, зокрема в аналізі імперативних змін у договірному праві, розгляді практики застосування форс-мажорних положень і визначенні проблем, які виникають у правозастосуванні. У ході наукового дослідження використовувалися загальнонаукові методи пізнання: аналіз для дослідження нормативно-правових актів, синтез для поєднання окремих аспектів у єдину картину, системний метод для розуміння взаємодії правових норм у договірному регулюванні, а також порівняльно-правовий метод для аналізу змін у регулюванні договорів до та після введення воєнного стану. Результати дослідження показують, що введення воєнного стану в Україні призвело до значних імперативних змін у регулюванні договірних відносин. Зокрема, договори, укладені після початку воєнного стану, містять більш чіткі положення про форс-мажор, що дозволяє сторонам враховувати ризики та адаптувати договірні зобов’язання до нових умов. Натомість договори, укладені до воєнного стану, часто не містять відповідних положень, що створює правову невизначеність. Практичне значення дослідження полягає у визначенні рекомендацій щодо вдосконалення правового регулювання договірних відносин в умовах воєнного стану, впровадження яких сприятиме зниженню правових ризиків, підвищенню стабільності договірних зобов’язань та адаптації судової практики до кризових умов.

Published: January 2025

This study discusses the utilization of Geographic Information Systems (GIS) for land parcel mapping at the Ministry of Agrarian Affairs and Spatial Planning/National Land Agency (ATR/BPN) in Kolaka Regency. The implementation of GIS through the Land Activity Computerization Program (KKP) aims to enhance efficiency and accuracy in land registration processes while providing legal certainty over land ownership. By integrating spatial and textual data, GIS can deliver comprehensive information, enabling faster and more structured land mapping. Data obtained from the KKP at the Kolaka Land Office shows a significant increase in the number of registered land parcels after implementing GIS. Prior to GIS adoption, land registration data was limited and fragmented, with spatial data that lacked accuracy and accessibility. Post-implementation of KKP, the number of registered land parcels increased by 85% over the last 10 years, reflecting the system's improved effectiveness in supporting land administration. The results indicate that GIS can accelerate the mapping process, improve data accessibility, and facilitate spatial planning. With thematic maps generated, the ATR/BPN can conduct better analyses of land quality and legal status. Additionally, GIS helps identify areas requiring data updates, thereby continuously enhancing the quality and accuracy of land information. This study concludes that GIS is not only a mapping tool but also a strategic solution that increases efficiency and transparency in land management. These findings provide a potential model for other regions aiming to optimize land registration through GIS-based technology, supporting legal security and certainty for the public.
A Holistic Approach for Detecting Socialbots on Twitter: Integration of Diverse Features
Authors: Owais Muhammad , Shoaib Muhammad , Waseem Muhammad
Published: January 2025

The usage of social media platforms has grown, offering individuals diverse avenues for communication, expressing opinions and sharing online content. However, this surge has also given rise to the emergence of social bots, which are programmed accounts designed to imitate human behavior. Such bots possess the capability to disseminate false information, manipulate financial markets, aid terrorism, and disrupt democratic processes. To tackle this issue, various approaches have been utilized to detect social bots, including approaches based on profiles, time patterns, content analysis, behavior, and network characteristics. However, neither of the approaches effectively combines all these features to implement social bot detection comprehensively. This paper introduces an ensemble methodology that merges profile, behavioral, temporal, network, graph, and content-based attributes, culminating in a comprehensive model for discerning social bots on the Twitter platform. We utilize the Twibot-22 dataset for conducting experiments and evaluate the performance of our approach against benchmark models. The XGBoost model, with an accuracy of 0.898, exhibited superior performance compared to the benchmark models. This research contributes to the continuous endeavor focused on safeguarding the authenticity of tweet content and mitigating the risks associated with social bots on social networks.

Authors: Javaid Azka , Naz Shumaila , Hameed Sohail
Published: January 2025

Water pollution poses significant threats to ecosystems and human health. Sustainable, eco-friendly technologies for treating contaminated water using phytoremediation offer a promising solution to detoxify the polluted water. This study uses floating treatment wetlands (FTWs), a cost-effective phytoremediation technology, to treat contaminated water by employing indigenous plants and their associated plant growth-promoting rhizobacteria (PGPR). Plant samples were collected from the banks of a water channel in the sub-tropical region of Karima, Attock, Pakistan (33°39'04.2"N, 72°42'14.6"E). The plant species selected for this study were Cocklebur (Xanthium strumarium), Vetiver grass (Chrysopogon zizanioides), Parthenium (Parthenium hystophorous), Bermuda grass (Cynodon dactylon), and Hemp (Cannabis sativa), because of their potential for heavy metal uptake and tolerance. PGPR isolates associated with these plants underwent biochemical characterization, yielding positive results and further validated through nucleotide homology to ensure the selection of the most effective strains. The FTWs were seeded with Vetiver grass and Bermuda grass, both known for their robustness and high phytoremediation capacity. Physicochemical analyses of the contaminated water revealed significant reductions in heavy metal concentrations, including cadmium reduced (to 0.0000 mg/L), nickel (to 0.0016 mg/L), and chromium (to 0.0117 mg/L. These results underscore the effectiveness of the FTW system in improving water quality. Present work demonstrates that the integration of Vetiver grass (Chrysopogon zizanioides) and Bermuda grass (Cynodon dactylon) with their symbiotic bacteria, Stenotrophomonas maltophilia, in FTWs, is a viable and sustainable method for the remediation of heavy metal-contaminated water, offering a practical solution for environmental restoration and pollution control.
Eco-friendly bioplastic from Pontederia crassipes: cellulose and carboxymethyl cellulose biopolymers for sustainable, biodegradable bioplastic film
Authors: Abiyoga M , Saravana Kumari P.
Published: January 2025

Expanded usage of polyethylene film in different industries lead to accumulation of plastics in the environment, which cause pollution and toxicity to life forms. It can be replaced by the bioplastics which are biodegradable, biocompatible, eco-friendly, and can be obtained from renewable sources at low cost such as plant weeds. The biopolymer, cellulose can be extracted from aquatic weeds since they are abundantly available from aquatic system, easy and safe to handle, and biocompatible. Pontederia crassipes an aquatic floating weed, widely dispersed in surface of polluted rivers and ponds. Directed to remove from water bodies by EPA due to its negative impacts on aquatic animal life and the collected biomass as such cannot be used as a feed due to the presence of polyphenols and nitrates. In the current study, about 30% of cellulose was extracted by delignification and bleaching of weed biomass collected from a river. Extracted cellulose was converted into another form of derived polymer, known as carboxy methyl cellulose (CMC) by treating with monochloro acetic acid. Biodegradable bioplastic was prepared using gelatin as gelling agent and glycerol as plasticizer by varying concentrations. Properties of the extracted cellulose, CMC, and bioplastic from cellulose and CMC, were analyzed by measuring film thickness, tensile strength, elongation point, FTIR, and antioxidant assay. About 25.7 µm thickness cellulose biofilm exhibited higher tensile strength of 55.3 MPa at dry, 45.5 MPa at wet condition and 24 µg/ml of antioxidant activity was observed. This research highlights the potential of utilizing water hyacinth, a typically problematic weed, to develop sustainable biopolymers that address the growing environmental concerns associated with conventional plastic waste. Thus, this research work provides a potential biological safe approach to prepare bioplastic film for commercial applications. While, gelatin is costly, a suitable, cheap alternative need to be identified to reduce the cost of production of the bioplastic film.  However, further efforts are required to enhance the scalability of the product.

Under the conditions of a changing climate, slope runoff from arable lands undergoes varying degrees of significant changes in different parts of the temperate climate zone. The article, based on a review of published data and the author’s generalizations, examines the main trends in the transformation of soil erosion in the largest agricultural regions of the world with an emphasis on the European Territory of Russia (ETR). For ETR, based on observations of slope runoff during snowmelt, a clear trend of its reduction was revealed, starting from the 1990s up until the complete cessation of the forest-steppe zone in the west and its replacement by mixed snowmelt/rainfall erosion in the west of the steppe zone. A general reduction in the rate of soil losses within the southern megaslope of ETR was revealed for all landscape zones except for the south of the steppe zone based on estimates of the rate of sediment deposition in the bottoms of the dry valleys of first-order catchments. It is shown that climate warming contributes to an increase in the frequency of extreme rainfall events, which is especially significant in Western and Central Europe. This trend is still less evident within the ETR. Structural changes in land use have affected Russian agriculture to the greatest extent in recent decades. Here, up until the beginning of the 21st century, there was a significant reduction in arable land, which since the beginning of the second decade of the 21st century has been replaced by the restoration of arable land areas in the forest-steppe and steppe zones. In North and especially in South America, over the past two decades, zero tillage has been used on significant areas of previously arable land, which has significantly reduced the rate of soil erosion. At the same time, in a number of regions of the forest-steppe zone located within the East European Plain, since 2014, the share of row crops has increased sharply (up to 30 % of the total area of cultivated land), which has increased the likelihood of severe erosion.
The history of foundation and development of the Makkaveev’s laboratory
Authors: Chalov R. S.
Published: January 2025

The N.I. Makkaveev Research Laboratory of Soil Erosion and Channel Processes was organized on the initiative of Professor N.I. Makkaveev in 1969 in accordance with the Resolution of the USSR State Committee on Science and Technology as a response to the Government Resolution “About urgent measures to protect lands from water and wind erosion of soils”. The paper presents that the basis of the new laboratory was formed by scientific teams (groups) created by N.I. Makkaveev since 1953 at Moscow University in various directions in the study of erosion and channel processes. Together with the development of the theory and methodology of erosion and channel studies, a unified doctrine of the erosion-accumulative fluvial process and erosion-fluvial systems, the laboratory’s research has always been closely linked to the solution of practical problems – protection of soils from erosion, regulation of river channels under development of water and other river resources, prevention of hazard manifestations of erosion and channel processes, on the one hand, and training of highly qualified specialists, on the other. The laboratory has overcome all the difficulties that have arisen in science development since the 90s of the 20th century and continues to function successfully at present, receiving support from the Russian Science Foundation, state and other programs, state contracts for the implementation of specific scientific and production tasks. The main scientific results of the 55-year activity of the laboratory are formulated.

The Cognitive Behavioral Therapy (CBT) approach has been proven effective in helping individuals overcome various psychological issues. In the context of Islamic counseling, integrating CBT with Islamic values offers a holistic solution that addresses both psychological and spiritual aspects of clients. This approach employs cognitive restructuring and behavioral modification techniques combined with Islamic principles such as muhasabah (self-reflection), tawakkal (trust in God), and worship practices. This study demonstrates that the application of Islam-based CBT enhances counseling effectiveness, particularly for Muslim clients, as it aligns with their cultural and religious beliefs. However, the success of this approach relies on counselors proficient in both aspects. With the development of a more structured Islamic CBT counseling model and increased public awareness, this approach holds significant potential for broader implementation.

This research aims to examine the role of Islamic counseling in overcoming Quarter Life Crisis (QLC) and increasing the mental and spiritual resilience of individuals. The research used a qualitative approach with a literature study method, combining findings from the fields of Islamic psychology and faith-based counseling. The results showed that QLC, which is commonly experienced by individuals aged 18-29, can impair mental and spiritual well-being. Internal factors such as childhood experiences and external factors such as family support play an important role. Islamic counseling, with spiritual principles such as tawakal and ikhlas as well as dhikr practices, proved effective in providing emotional support and strengthening mental resilience in the face of life's uncertainties. This approach helps individuals manage anxiety, indecision and life stress through strengthening religious and psychological values. This research is expected to contribute to developing a holistic Islamic counseling approach, as well as providing practical guidance for counselors and individuals facing QLC
