Published: December 2023

Oxidative stress is one of the mechanisms that causes pancreatic damage and the complications of diabetes mellitus (DM). Activating Nuclear Factor Erythroid 2-Related Factor 2 (NRF2) is important in protecting pancreatic cells from oxidative stress and inflammation. Clitoria ternatea L. (CT) flower was studied for its antioxidative effects in diabetic rats. Indeed, there has not been a lot of study on how CT impacts melatonin levels and NRF2 activity. CT flower was extracted using maceration procedures with 96% ethanol. The male Wistar rats (n=25) were randomly divided into five groups, including the control group, which received normal saline orally for 14 days. Diabetes groups received intraperitoneally (i.p.) streptozotocin (STZ) as a single dose (45 mg/kg, i.p.). Normal saline, CT (100 and 200 mg/kg), and metformin (150 mg/kg) were orally administered to diabetic rats for 14 days. The melatonin, NRF2, and malondialdehyde (MDA) levels were measured in serum. CT flower extract had no effect on melatonin levels in diabetic rats (p>0.05), but significantly increased NRF2 levels and decreased MDA levels (p<0.05). CT can activate NRF2 and reduce oxidative stress in DM, and its administration may prevent diabetes complications.
Locality, Equality, and Piety: Pesantren Ecofeminism Movement in Indonesia
Authors: Sulistyati Mardian
Published: December 2023

The ecofeminism movement in Indonesia is generally territorial and intersectional but tends to be secular. This study shows the emergence of ecofeminism ideas integrated with Islamic values in the form of pesantren. Unlike other ecofeminisms—which were generally born as a response to women and environmental issues an sich, pesantren ecofeminism was an effort to rise from the mental-class and economic-class trauma of peasant society. I used a subsistence perspective, which led me to the Pesantren Ekologi Ath-Thaariq in Garut, West Java, Indonesia. I combined Harvard and Longwe frameworks to analyze pesantren’s activity, access, control, and equivalence level. This article contains the pesantren ecofeminism concept in viewing the environment through faith, local wisdom, and piety. This study further examines the ability of pesantren to break unequal power relations between humans and between humans and non-humans, instead of continuing the patriarchal tradition and its kiai-centric system.
Collegial Leadership and Election in Muhammadiyah: Institutional Ways to Diffuse the Religious Authority of Leaders
Authors: Kim Hyung-Jun
Published: December 2023

Muhammadiyah advocates for the equal and rational standing of Muslims, underscoring that judgment lies solely with Allah and discouraging hierarchical leadership privileges. This viewpoint permeates its organizational structure, portraying leaders as dedicated members without elevated status. Alongside its emphasis on egalitarianism and rationality, Muhammadiyah has developed organizational mechanisms, aimed at preventing the concentration of religious authority in the hands of popular leaders. The article explores two of these mechanisms, collegial leadership and elections. Collegial leadership establishes a collective oversight body, ensuring equal rights for each leader. The unique election system, requiring the choice of thirteen candidates, prevents individual dominance and a potential landslide victory. By minimizing differences, emphasizing similarities, and discouraging the showcasing of individual merits and popularity, these mechanisms effectively diffuse religious authority within Muhammadiyah’s leadership.

Authors: Olaleye Oladipupo , Akande Samson
Published: December 2023

The development of coronavirus disease 2019 (COVID-19) vaccine is widely regarded as a tremendous scientific progress. However, the level of vaccine acceptance has been a concern in Nigeria. Thus, we conducted a study to analyze the perception and acceptance readiness for COVID-19 vaccine among Nigerians, yielding analysis data that could inform policy for raising the COVID-19 vaccine acceptance rate. A total of 302 respondents were surveyed in this cross-sectional study to explore their perception and acceptance readiness for COVID-19 vaccine. A total score of ≤14 was considered having negative perception of COVID-19 vaccine whereas a score >14 was regarded as having positive perception. Most respondents (71.2%) had a negative perception of the vaccine. The majority of these respondents (96.7%) had not been vaccinated, out of which 46.6% claimed to be willing to take the vaccines if they were provided free of charge, while 15.1% expressed their willingness to be vaccinated even if payment was required. There was no variable associated with readiness or non-readiness to take the COVID-19 vaccine. Major reasons for non-readiness include doubt about the vaccine authenticity/safety/effectiveness (59.2%), low level of trust in the government (12.6%), and fear of side effects (10.7%). In conclusion, to boost the COVID-19 vaccine uptake in Nigeria, both governmental and non-governmental bodies should participate in continuous public engagement to assure the public that the vaccine is safe and effective.

Published: December 2023

Two-photon polymerization (TPP) is a sub-classification of vat photopolymerization. It has been widely used to fabricate micro/nano hierarchical structures that have the potential to be used to tune the fluid flow in chips. The present work first studied the influence of laser power on the feature size of TPP-fabricated 2D structures. It was found that the increase of laser power from 1.0 μW to 1.4 μW leads to the feature size increasing from 203 nm to 307 nm. Then, the effect of scanning parameters on the accuracy and surface quality of 3D structures was investigated. The arrangement of the voxels at different scanning strategies explains the mechanisms of the variation of accuracy and surface roughness. Finally, the pinecone structures with micro/nano hierarchical features were built and evaluated for their water repellence. The increase in the number of rows of pinecone structures significantly enhances the water-repellent performance.

For the public and private sectors, especially those dealing with the international world, monitoring exchange rate movements is very important. However, in the current conditions of volatility, uncertainty, complexity and ambiguity (VUCA), exchange rate projections become very challenging. Behavioral Equilibrium Exchange Rate (BEER) is a model used to estimate an exchange rate that is considered balanced based on fundamental factors. In connection with this, the author intends to inform you about BEER and its benefits. Therefore, this paper aims to estimate the balance of the real exchange rate (RER), so that exchange rate movements outside of equilibrium (misalignment) can be identified. The method used in this paper is the Error Correction Model (ECM). The author uses quarterly data with the aim of getting a long data series and more accurate estimation results. Meanwhile, the explanatory variables consist of productivity, interest rate differential, foreign reserves, terms of trade, and risk premium. From the estimation results, it is known that changes in productivity, interest rate differential and foreign exchange reserves have a significant positive effect on RER movements. The risk premium has a significant negative effect, while the terms of trade are not significant. It is hoped that the results of this simple analysis will provide additional insight for policy makers and economic practitioners in understanding the dynamics of the real rupiah exchange rate and efforts to maintain its stability. It is also hoped that this article will provide a strong basis for considering more effective policies in managing the rupiah exchange rate.

On the battlefield, the Ukrainian military uses towed anti-aircraft guns such as the S-60, which are still effective when used against ground targets. 57-mm anti-aircraft artillery systems are currently ineffective against modern air targets such as combat aircraft, drones and attack helicopters.
But taking into account the caliber of the anti-aircraft installation, it can be used not only for its intended purpose, but also for firing at manpower and lightly armored vehicles with direct fire, and not only that. S-60 ammunition is powerful due to its caliber and sufficient rate of fire. When installing these guns on the chassis of trucks, it turns them into mobile self-propelled artillery installations and quite versatile and easy-to-use weapons.

This work presents the methodology of using wasted lubricants as a highly efficient fuel as water-fuel emulsions, which containing up to 70% water. They burning in burners under conditions of action high-frequency electrical discharges. It has been shown that the viscosity of a water-oil emulsion with a high water part (more than 50%) outweighs the viscosity of pure oil. With a low water part (10-20%), the emulsion is the most stable. With more water, the semi-delamination time decreases. Therefore, it is necessary to spray the emulsion near the site of the making.
The results of natural experiments and prospects of the proposed methodology are given. Combustion of a water-in-oil emulsion with a volume content of 50-70% water is possible in the presence of a discharge of high-frequency signals. Independent combustion of the emulsion without the support of a small diesel fuel torch is possible with sufficient heating of the combustion chamber. To implement combustion, the burner for liquid fuels was modernized by adding a pre-chamber between the burner and the nozzle or boiler.
To organize effective spraying of water-oil emulsion with a large amount of water (up to 70%), it is necessary to ensure sufficient heating of the emulsion in the pipelines. First, this reduces its viscosity, making it easier to pump the emulsion through the supply systems of the spraying device. Otherwise, it is necessary to serve under a pressure, so that the water at a high temperature (above 100 ° C) is remained liquid. When leaving the nozzle under pressure, the water “boils” (“micro-bump” drops of emulsion), which further disperses the burning liquid.
The peculiarity of this burner is the action of a high-frequency streamer in the area of spraying emulsion droplets inside the forechamber. The use of water-fuel emulsions allows to reduce emissions of nitrogen oxides and carbon monoxide, reduce its fire and explosion hazard during transportation and storage. Effectiveness assessment of this complex showed that energy expenditures can reach percents of levels compared to full heat release.Thus, the possibility of using such water-oil emulsions as alternative fuels is shown.
Keywords: water-oil emulsion, high-frequency electric discharge, combustion, torch.

The analysis of mathematical models of the flight of projectiles has been carried out, it is shown that the nature of their provision varies depending on the degree of reliability of the representation of the real physical process of its flight by a mathematical model, the adequate consideration of certain forces (moments) acting on the projectile, as well as the level of information about external flight conditions. In the simplest mathematical model with three degrees of freedom, the projectile is considered as a material point that moves in the atmosphere under the influence of gravity and full aerodynamic force. The dynamics of projectile flight is most completely described by the mathematical model of the movement of a solid body with six degrees of freedom. In the intermediate model with four degrees of freedom, all aerodynamic forces are taken into account, the orientation of the projectile is characterized by taking into account the angle of nutation, and the kinetic energy of the rotational movement is taken into account through the angular velocity of the projectile around its axis of symmetry. The process of restori ng the coefficients of aerodynamic forces using the material point model does not provide the necessary accuracy and adequacy of the description of the projectile flight process; of the modified material point model is much simpler (the least complex) compared to the model of the motion of a rigid body with six degrees of freedom due to the smaller number of coefficients and differential equations included in its composition. The differential equations of the modified material point model are provided - the equation of motion of the center of mass and the equation of nutational oscillations of the projectile in scalar form; an assessment of its accuracy (adequacy) was carried out on the example of the 155-mm PF projectile M2000, one of the family of projectiles of the company Denel Naschem – Assegai M200X Series 155-mm Projectiles. A comparison of the characteristics of the 155-mm PF of the M2000 projectile calculated according to the 6DoF model and the modified material point model showed their high convergence; the error does not exceed 1%.

Controversial Issues of Inheritance of Residential Premises Acquired at the Expense of Maternal (Family) Capital
Authors:   Udmurt State University, Khodyreva Ekaterina A.
Published: December 2023

According to the Concept of State Family Policy approved in the Russian Federation, one of the significant measures that influenced the increase in the birth rate in the country was the provision of maternity (family) capital for families with children at the expense of the state budget. However, the application of the provisions established by special legislation, especially in terms of allocating a share in the acquired residential premises to minor children, caused problems of their practical implementation, arising not only during life, but also after the death of parents. The purpose of writing the article was to identify typical cases of participation of heirs in disputes arising in connection with the inheritance of residential premises acquired in whole or in part at the expense of maternal (family) capital. Special attention is paid to the problem of inheritance of residential premises after the death of a person who did not fulfil the obligation to allocate a share to minor children during his lifetime. At present, both in science and in the law enforcement sphere, a judgement has been formed on the need to refuse heirs to issue a certificate of inheritance in part of the residential premises acquired at the expense of the maternal (family) capital, before determining the shares of both heirs and the deceased parent in court. This approach is based on a misunderstanding of the legal nature of the obligation to allocate shares to minor children. The author makes a conclusion about the termination of an unfulfilled public duty by the death of a person and the impossibility of applying the norms of the law of obligations.
Acquisition of Title to Ownerless Linear Facilities under a Simplified Procedure

Published: December 2023

The article considers the model of transfer of ownerless immovable things into the ownership of public-law entities envisaged by Article 225 of the Civil Code. The special procedure for acquiring the title to ownerless immovable property cannot be regarded as a simplified version of the emergence of ownership rights of public-law entities under the statute of limitations. This procedure is of an exceptional nature, by its legal nature belongs to the powers of forced transfer of property into public ownership on a par with such extraordinary cases as requisition and confiscation. Extension of this procedure to private entities, which turn ownerless linear objects into their ownership, is not justified. Transfer of ownerless linear facilities by energy system operators into their ownership should be regarded as an acquisition of ownership rights to a component part included in an indivisible thing. This will allow to maintain the balance of public interests and the rights of the former owner.

The economic situation in the world and the challenges of our time forced many Russian issuers to refuse future depository programmes and curtail the existing ones, which were issued by the relevant acts of the Bank of Russia, with the exception of certain issuers listed by the Government of the Russian Federation. The peculiarities of the circulation of the financial instruments under consideration and the procedure for exercising rights certified by these depositary receipts affect the approaches of judicial practice being formed. This article examines the competence of the court in disputes arising from the exercise of rights certified by depositary receipts; related to automatic or forced conversion of depositary receipts into shares of Russian issuers; on recovery of damages, etc. Ways are proposed to form judicial practice in terms of determining the competence of the court and applying the relevant rules of procedural law. The current public legal regime and public interests of the state are analysed, as well as the competence of the state arbitrazh court in disputes involving persons in respect of whom restrictive measures have been introduced. Possible approaches to judicial practice are formulated that meet the challenges of modernity in the stock market in order to protect the rights of investors, as well as the tasks of effective legal proceedings.

Authors: Yang Jian
Published: December 2023

The China's Pilot Free Trade Zones are an important hub for the promotion of China's domestic and international double circulation,and is the key to opening up the "double circulation" blockage and promoting a wider range of reform and opening up to build a new development pattern. Although China's Pilot Free Trade Zones have achieved a lot in promoting the construction of a new development pattern,there are still five problems:the regional layout needs to be optimized, the domestic trade circulation test task needs to be strengthened,the level of policy and system coordination needs to be improved,the cultivation of innovative development driving force needs to be enhanced, and the risk prevention and control system needs to be improved. Under the background of China's active construction of a new development pattern, it is necessary to further optimize the layout of the Pilot Free Trade Zones, increase the domestic trade circulation development test task, strengthen the coordination and cooperation of various policies and systems, cultivate the innovative driving force of high-quality development, enhance the ability to prevent and defuse opening risks, and further play the role of the Pilot Free Trade Zones in serving the new development pattern.
Die ungleiche Entwicklung der Regionen im vormodernen Ost(mittel)europa. Forschungsperspektiven, Indikatoren, Kontexte

Published: December 2023

Laut Wirtschaftslexikon wird die ungleiche Entwicklung als Kluft zwischen den hochentwickelten, industrialisierten Ländern und den agrarischen, vorwiegend Primärprodukte erzeugenden Gebieten definiert.1 Historiker und Historikerinnen weisen jedoch schon seit Jahren
darauf hin, dass die auf der Welt herrschende Ungleichheit aus Strukturgegebenheiten erwächst, die sich sehr langsam herausbilden und ebenso langsam verwischen. Sie sind demzufolge nicht die Konsequenz der industriellen Revolution, sondern begegnen durchaus in vormodernen Gesellschaften.2

Aim: This study aims to determine the significance of chronic hyperglycemia for the reduced efficacy of eradication therapy in patients with type 2 diabetes mellitus (T2DM) and Helicobacter pylori (H. pylori)-associated upper gastrointestinal tract pathology as well as for H. pylori survival.
Methods: A prospective randomized study with the participation of 180 patients (87 men and 93 women) with H. pylori-associated upper gastrointestinal pathology was carried out. Ninety of these patients were with T2DM and 90 were without diabetes mellitus (DM). The patients were divided into 4 groups of 45 patients: the group 1 included non-diabetic patients treated with the classical triple eradication scheme; the group 2 included patients with T2DM treated with the classical triple eradication scheme; the group 3 included non-diabetic patients treated with bismuth quadro-therapy; the group 4 included patients with T2DM treated with bismuth quadro-therapy. The presence of H. pylori and evaluation of eradication efficacy was carried out using the Helix breath test.
Results: The effectiveness of 1st line anti-Helicobacter therapy was higher (88.2%) in patients without diabetes in comparison with the group of patients with concomitant T2DM (74.7%). The efficacy of classical triple eradication therapy in patients with concomitant T2DM was 69.1%, and quadro-therapy was 80.5%. There was significantly lower effectiveness (P < 0.017) of eradication therapy in patients with T2DM and glycated hemoglobin (HbA1c) level ≥ 7.0% as compared with the group of patients in whom the target (≤ 6.5%) level of HbA1c was achieved.
Conclusions: Chronic hyperglycemia has a favorable effect on the viability of H. pylori bacteria in patients with T2DM. A hypothesis explaining the reduced efficacy of eradication therapy in patients with hyperglycemia has been proposed.
Review Article Update of Multiple Sclerosis

Published: December 2023

Multiple sclerosis MS is an autoimmune demyelinating disease of the central nervous system the etiology of which remains so far unknown and which probably involves senetic, immune, inflammatory, as well as environmental factors. OBJECTIVES: A review of the current and past literature on multiple sclerosis to provide a concise and comprehensive educational resource mainly for postgraduate medical students, but also for undergrad unte medical colleges students as well as other medical practitioners and their patients. The aim being to present a simplified and clinically relevant summary of the main manifestations, and management of multiple sclerosis, with an update on current theories of pathophysiology, actiology and the basis behind the therapeutic agents used in current clinical practice. METHODS: The standard medical texts and journals relating to MS were consulted as well as reliance on the own experience of patients attending the teaching hospitals, and clinics in Benghazi Libya with a diagnosis of multiple sclerosis. Local and worldwide epidemiological published data were also reviewed. RESULTS: The incidence of multiple sclerosis varies worldwide. Eastern Libye is an area of high risk MS incidence. The importance is emerging of a genetic role in the already known immune pathogenesis of multiple sclerosis. Diet and light have regained importance in the etiology of the disease. Investigations are advancing and help to differentiate the disease from other mimicking conditions. Biomarkers help to define diagnosis and determine prognosis. CONCLUSIONS: Multiple sclerosis is an important neurological disease with protean CNS manifestations which must be considered in the differential diagnosis of neurological symptoms at all ages, although commonly considered a disease of young people, especially females. A countrywide database may help to collate efforts and resources, as well as unify data regarding the number and presentation of patients, to assess their requirements.
