The accumulation of energy in the power system is necessary in order to harmonize the power of production with the power of consumption and to maintain the stability of the supply of electricity. The necessity of energy accumulation is particularly pronounced in power systems with a greater share of solar and wind power plants, whose power generation strongly depends on weather conditions. The accumulation of energy enables fast primary and secondary regulation of the generated power, while in the case of larger accumulations it can also participate in tertiary regulation. A fully developed technology with extensive exploitation experience for the accumulation of energy in the power system, both in the world and in Serbia, is the application of pumped hydroelectric energy storage plants. The paper analyses previous experiences in the application of pumped hydroelectric energy storage plants, as well as some newer technical solutions aimed at maximum utilization of natural potentials for the accumulation of hydropower. In addition, given that Serbia is one of the countries in the world with a large share of electricity production from coal, some of the modern solutions for energy accumulation within thermal power plants are also considered.

Based on the enacted laws and decrees related to buyers-producers, Elektrodistribucija Srbije has defined the procedure, necessary documents as well as general technical conditions for the production facility, in order to gain the status of buyer-producer. Within the procedure for acquiring the status of buyer-producer, three Sectors within the Elektrodistribucija Srbije and Elektroprivreda Srbije are included. In The Elektroprivreda Srbije, DP Kragujevac adopted a model of monitoring the realization of acquisition of customer-producer status by forming an Database with defined fields in which all relevant data used in the process of acquiring the status of buyer-producer are monitored. The base is designed in such a way that each sector enters data from its scope of work, and since the document is located on the shared folder, the view of the entered data can be monitored by everyone involved in the process. In the next step, the idea is to create an application for monitoring implementation with the possibility of obtaining the necessary reports in cooperation with the ICT of The Elektrodistribucija Srbije. In this way, it is achieved that at any time for each submitted request there is information about the status of the potential buyer-manufacturer as well as records of the entire documentation to be submitted in the procedure.

Published: December 2023

Experimental results on the generation of accelerated particles in solid matrices saturated with isotopes of hydrogen under electric discharge are presented. Registration of accelerated particles was carried out by measuring the spectra of charged particles emitted by the target. The emission of α-particles with an energy yield of 10…14 MeV,
the yield of protons with an energy in the range of 5.8…7.8 MeV, and the yield of neutrons with an energy in the range of 3…10 MeV were observed. These observations may indicate that the low energy nuclear reactions took place under investigated conditions.
TAGGING EFFICIENCY ESTIMATION IN EXPERIMENTS WITH A COHERENT BREMSSTRAHLUNG BEAM
Authors: Burdeinyi D.D. , Ganenko V.B.
Published: December 2023

The angular dependences of the coherent and incoherent parts of the coherent bremsstrahlung (CB) are different, thus the CB beam tagging efficiency differs from that of the bremsstrahlung. It has energy dependence close to the CB beam spectrum and depends on the CB peak energy. Thus, in the course of the cross section measurements, the systematic, measurements of the tagging efficiency should be usually produced. The paper shows that tagging efficiency can be estimated computationally by taking into account the background contribution to the detectors of the tagging system. This allows one to get cross sections simultaneously with the cross section asymmetry measurements in the case when the systematic tagging efficiency measurements were not performed.

REGULARIZATION OF WAKEFIELD IN A WEAKLY NONLINEAR REGIME
Authors: Demydenko I.V.
Published: December 2023

In blowout regime of wakefield excitation, strong chaotization of wake occurs. However, for electron-positron colliders and X-ray microscopes, a weakly nonlinear regime is proposed with the formation of a regular short chain of bubbles. To increase the efficiency of the wakefield accelerator, it is necessary that not separate bunches participate. In this paper in 2D plane geometry, the dependence of the number of formed bubbles and their regularization on the degree of wake non-linearity and parameters: driver current, ion mobility, transverse plasma size and profile is studied. We will show that in a weakly nonlinear regime the regular chain of bubbles becomes longer.

Authors: Ade Indra
Published: December 2023

Powder technology is one of the most frequently used alumina manufacturing processes. The powder must be made as small as possible because the mechanical strength of the ceramic is inversely proportional to the size of the powder. Powder grinding can be done using a horizontal ball mill. Ball mill is equipment that functions to grind powdered material with the help of grinding balls inside it. The purpose of this study was to determine the effect of variations in the rotational speed of the mill jar on the quality of alumina powder products at room temperature. The research method used is the experimental method by testing the alumina powder material with variations in the rotation speed of the mill jar 100 rpm, 125 rpm, 150 rpm, 175 rpm, 200 rpm, 225 rpm and 250 rpm. The results of the study showed that variations in the rotational speed of the mill jar affected the size of the alumina powder which was ground using a ball mill. The best mill jar rotation speed from this test was 150 rpm, resulting in a sub-micron size percentage of 8.0% and a reduction in the size of alumina powder from 70.28 µm to 44.07 µm.

El laboratorio de investigaciones bioquímicas de la Universidad de Zaragoza y los inicios de la Ciencia de Coloides e Interfases en España: un ejemplo de ciencia periférica, 1918-1936
Authors: Hidalgo Álvarez Roque
Published: December 2023

This article presents a historical approach to the beginnings of Colloid and Interface Science in Spain. The pioneer in the colloidal domain research was Antonio de Gregorio Rocasolano, professor of General Chemistry, and founder of the Biochemical Research Laboratory of the University of Zaragoza in 1918. The pioneering work carried out by Rocasolano with silver and gold sols synthesized in his own laboratory and the use of the ultramicroscope to follow the colloidal aggregation processes turned the Biochemical Research Laboratory into a research center capable of obtaining interesting scientific-technical results that have remained valid to the present day. It is an example of high-quality research carried out in the periphery of Spanish science. To this end, Professor Rocasolano surrounded himself with brilliant young researchers such as Juan Martín Sauras, Jes.s Camón Cano, María Antonia Zorraquino Zorraquino and José María Albareda Herrera, establishing solid collaborative relationships with prestigious foreign researchers such as Richard Adolf Zsigmondy and Heinrich Jakob Bechhold. In November 1936 Rocasolano agreed to be the president of the Purging Committee of the University staff (Committee A). This Committee purged at least 40% of the Spanish university teaching staff. This repressive activity of Professor Rocasolano overshadowed his brilliant scientific career, which is unknown to the vast majority of Spanish scientists.
Panic buying Perspektif Ekonomi Syariah
Authors: Soumena Fadly Yashari , Nasar Muh , Hajar Nurul
Published: December 2023

Panic buying merupakan sebuah fenomena yang terjadi ketika konsumen secara berlebihan membeli produk dan menyebabkan kelangkaan sementara di pasar. Fenomena ini menjadi sangat relevan selama periode krisis atau keadaan darurat yang memicu kekhawatiran masyarakat. Dengan tindakan tersebut, maka secara langsung dapat berpengaruh pada ketidakstabilan harga dan komoditas di sektor pasar yang diakibatkan karena pembelian secara berlebihan. Ketika terjadi panic buying, permintaan yang tiba-tiba meningkat secara drastis melebihi pasokan yang tersedia, mengarah pada peningkatan harga yang signifikan dan penipisan stok barang. Dengan begitu,  penelitian ini bertujuan untuk mengkaji tindakan panic buying dan relevansinya dengan Ikhtikar dalam pandangan Islam. Ikhtikar merujuk pada praktik menimbun atau menyimpan barang dengan tujuan untuk memanipulasi harga dan mengambil keuntungan dari keadaan pasar yang tidak stabil. Dalam perspektif ekonomi syariah, ikhtikar dianggap sebagai tindakan yang melanggar prinsip-prinsip keadilan dan kebersamaan. Adapun metode yang digunakan dalam penelitian ini adalah studi pustaka yang bersumber dari jurnal-jurnal ilmiah dan literatur relevan yang sudah ada sebelumnya. Melalui tinjauan tersebut, penelitian ini menganalisis dampak negatif yang ditimbulkan oleh panic buying dalam konteks ekonomi syariah khususnya tindakan panic buying pada masa pandemic yang tidak dapat ditoleransi dengan berbagai alasan apapun. Alasannya adalah perilaku tersebut mencerminkan keserakahan dan mementingkan diri sendiri, tanpa mempertimbangkan kepentingan bersama dan prinsip-prinsip keadilan yang ditegakkan dalam ekonomi syariah. Dalam kesimpulannya, panic buying dalam perspektif ekonomi syariah dapat melanggar prinsip-prinsip fundamental ekonomi syariah, seperti keadilan, kebersamaan, dan saling berbagi.
FUNCTIONAL STABILITY OF THE INVERTED PENDULUM AND ITS RELATION TO UNCREWED AERIAL VEHICLE WINGS THROUGH SYSTEM MATHEMATICAL MODELING AND SIMULATION
Authors: Al-Dosary Naji Mordi Naji , Zolotorevskiy Alex Greg , Schram Cassidy Paul
Published: December 2023

The flight instability of an uncrewed aerial vehicle (UAV) can be considered critical, and investigations of stability can be compared to the study of the stabilization of an inverted pendulum. This study investigated the stability of two dynamic systems, represented by an inverted pendulum and a simple approximation of an aircraft wing surface exposed to aerodynamic forces. This study illustrates the advantages of time-domain simulation for solving the differential equation of motion. The simulation used the Euler integration approach for various system parameters. Essentially, an aircraft in flight must constantly maintain pitch stability, which, in practical considerations, can be compared to the mechanism of a rotary motion represented by the up-swinging motion of an inverted pendulum. The pendulum may conserve the same concept as an aircraft’s acceleration, as both are affected by the same gravity and acceleration forces, in which the longitudinal stability of the aircraft must be ensured immediately upon takeoff. An inverted pendulum and a UAV aircraft system simulation were developed with basic MATLAB software. The inverted pendulum simulation showed that as the value of the spring’s stiffness at the limit of stability (klim) increased, the system became more convergent and, as a result, more stable. The stiffness of the spring at the limit of stability, klim = 32.69 N m-1 (i.e., equivalent to an initial angular rotation θ = 5 °), and the system’s stability were observed up to the value of klim = 179.79 N m-1, which resulted in an unstable short initial period. In addition, for the aircraft’s wing, the damping coefficient (clim) value was in the range of clim ≥ 10,000 N s m-1. Therefore, with the damping ratio ζ being equal to zero, the system vibrated consistently at its natural frequency (wn), never deviating drastically to become unstable.

Published: December 2023

Introduction. Timely detection and prevention of burnout syndrome in various occupational groups is an urgent task of occupational health, since this condition directly affects the health, working capacity, and quality of life in workers.
The purpose of the study. an analytical review of Russian literature on the prevalence, risk factors, and prevention of burnout syndrome in various occupational groups and the definition of criteria for the formation of risk groups.
The search for articles was carried out using information portals including eLibrary.ru, CyberLeninka, PubMed, Medscape, Google Scholar, Scopus, Web of Science. Inclusion criteria: search depth of eleven years (2012–2022), Russian original full-text articles in open access. Initially, one thousand eight hundred sixty five publications were identified, of which 38 cohort selected that met the inclusion criteria.
A high prevalence of burnout was revealed among health workers, educators, IT-specialists and law enforcement officials, slightly less among aviation service specialists, employees of the Ministry of Emergency Situations, media workers, bank employees, and miners. There are discussed leading risk factors for the development of burnout among employees in various fields of activity. A number of studies have studied the neurophysiological characteristics of patients with burnout syndrome, showing the relationship between burnout and affective disorders. Many studies discuss various approaches to the prevention and treatment of burnout syndrome, but the effectiveness of the proposed methods is evaluated only in a few studies. In modern conditions, there is a need for further research, conceptualization and systematization in managing job burnout.

Introduction. Construction is one of the most important sectors of the economy.
The aim is: to study the causes of development, structure, and prevalence of occupational pathology of construction workers in the Arctic.
Materials and methods. An analysis was made of the data of socio-hygienic monitoring “Working conditions and occupational morbidity” and the Register of extracts from occupational disease records (Order of the Ministry of Health of the Russian Federation dated May 28, 2001 No. 176) for 2007–2021 in the Russian Arctic.
Results. Over 2007–2021, construction workers in the Arctic were exposed to thirteen occupational hazards, seven of which (labour severity, harmful chemicals, noise, whole-body and hand-arm vibration, fibrogenic aerosols, cooling microclimate) caused the development of occupational diseases (n=252). Diseases of the musculoskeletal system (38.5%), respiratory organs (16.3%), and sensorineural hearing loss (17.1%) prevailed in their structure. Occupational diseases more often developed among welders (n=31), painters (n=291), mechanics (n=23), and plasterers (n=19). The level of occupational morbidity among construction workers (2.62/10,000 workers) is 2.9–6.3 times lower than for all workers in the Russian Arctic and 20.6–194.7 times lower than for workers in the mining and metallurgical industry of the Russian Arctic. During 15 years, occupational morbidity and the risk of developing occupational pathology (RR=1.29; CI 0.82–2.02) in construction workers did not change.
Limitation. The lack of data on working conditions at construction enterprises in the Russian Arctic in 1997–2006, which could have explained the changes of occupational pathology in 2007–2021.
Conclusion. To preserve the health of construction workers (primarily welders, painters, mechanics, plasterers), it is necessary to improve measures to protect them from the effects of increased labour severity, harmful chemicals and noise.

Introduction. Food monoazo dye E124 Ponceau 4R is used in the food, pharmaceutical, and cosmetic industries. An analysis of the available data on the evaluation of the genetic safety of E124 based on the main marker events of genotoxicity revealed their inconsistency, possibly associated with quantitative and/or qualitative differences in the studied samples for impurities.
The aim of the work is to evaluate the mutagenic activity in the micronucleus test in mice of several commercial samples of E124 present on the domestic market.
Materials and methods. Three samples of E124 from different manufacturers (India) were studied. To assess the identity of Ponceau 4R substances, there was used method of MIR-spectroscopy – universal ART technique. Aqueous dye solutions were administered to the stomach of male CBA × C57Bl6/j) mice at doses
of 125 to 2000 mg/kg twice with an interval of 24 hours and preparations were prepared 24 hours after the last injection. To assess the frequency of polychromatophilic erythrocytes (PCE) with micronuclei (MN), 4000 PCE were analyzed, the proportion of PCE among all erythrocytes – 500 cells per animal.
Results. Ponceau 4 R was determined in all samples. All E124 samples caused an increase in the frequency of PCE with MN (p < 0.05–0.001, T test) after exposure at all levels studied in a linear dose-dependent manner. The proportion of PCE from all erythrocytes did not change.
Limitations. The data obtained do not allow determining the mechanism of the genotoxic action of the test substance.
Conclusion. An analysis of the frequency of MN PCEs in the bone marrow in mice after a double injection at doses of 125–2000 mg/kg revealed the genotoxicity of three samples Ponceau 4R.

Introduction. Acrylamide is widely used in industry. Considering the potential danger of acute acrylamide poisoning, it seems urgent to search for new effective ways to protect and increase the body’s resistance to extreme exposure.
The purpose of the study is to conduct a comparative assessment of the protective effect of hydroxymethyluracil complex compounds when administering moderate lethal doses of acrylamide to laboratory animals.
Materials and methods. The subacute experiment was conducted on thirty outbred male rats weighted of 189–194 g. For 14 days, a toxicant was administered intragastrically at a dose of 20 mg per kg of body weight, then a single dose of 200 mg per kg of body weight was administered. Animals received complex compounds of hydroxymethyluracil with ascorbic acid and sodium succinate (50 mg per kg body weight), with acetylcysteine (500 mg per kg body weight) one hour before acrylamide. Against the background of the administration of complex compounds without acrylamide to the animals. Then one week later, an analysis of the mortality was carried out, and the weight coefficients of the liver and kidneys were determined in the surviving animals.
Results. When acrylamide was administered to animals at the level of average lethal doses, 4 out of 6 animals died in the positive control group. In the groups in which animals received, in addition to acrylamide, the compound of hydroxymethyluracil with ascorbic acid and sodium succinate, the death rate was
2 out of 6 rats. Among the animals that received the compound of hydroxymethyluracil with acetylcysteine, no mortality was recorded within 7 days, as in the group negative control.
Limitations of the study are that the protective effect of hydroxymethyluracil complex compounds was assessed only on one species and gender of laboratory animals.
Conclusion. The complex compound of hydroxymethyluracil with acetylcysteine has a significant protective effect on male rats under extreme exposure to acrylamide at the level of moderate lethal doses. For a more complete understanding of the mechanism of action and a final judgment about the protective properties of the being studied complex compounds, it is necessary to continue research with analysis of changes in other indicators of the health status of laboratory animals.

According to global estimates, there are 2.3 million new cases and 1.8 million fatalities due to lung cancer each year. Despite recent progress in diagnosis and treatment, persistent challenges highlight the urgent need for novel therapeutics and innovative approaches to combat lung cancer effectively. Accordingly, in the present study, we aimed to investigate the anticancer properties of potential inhibitors of HIF-1α, compound 7a and 7b. In the study, HTB-54 and BEAS-2B cell lines were used. MTT cell viability experiments were performed to determine the effect of newly synthesized HIF inhibitors 7a and 7b on cell viability under normoxic and hypoxic conditions. Quantitative expression levels of HIF1A were determined by real-time PCR approach. While the half maximum inhibitory concentration (IC50) of compound 7a in HTB-54 cells was 10.37 µM under normoxic conditions, it was found to be 10.63 µM under hypoxic conditions. The IC50 value of another HIF inhibitor 7b in HTB-54 cells was found to be 8.80 µM under normoxic conditions and 9.54 µM under hypoxic conditions. The expression level of HIF1A was found to be lower in cells exposed to compounds 7a and 7b under hypoxia compared to the control group. Conversely, in normoxia, HIF1A expression level in cells exposed to compound 7a increased 6.5-fold (p<0.0001) compared to the control group, while it was found to increase approximately 9-fold (p<0.0001) when exposed to 7b. Consequently, both compound 7a and 7b holds great promise for future therapeutic interventions to lung cancer.

Aims: Diagnosing celiac disease in children presents various challenges for pediatricians in the various clinical stages. Thus, the diagnosis of cases increased significantly, although children did not always present symptoms or clinical signs of the disease. In support of the diagnosis, several factors come into play: screening, serological tests, awareness of the presence of celiac disease and the factors that favor its occurrence.
Material and methods: We performed a retrospective study at the Pediatric Clinical Hospital "St. Ioan " Galati between January 1, 2014 and October 2022. In this study we included 2640 children with  suggestive symptoms of celiac disease.
Results: A number of 102 patients were diagnosed with celiac disease, recurrent abdominal pain being the most common symptom.
Social and economic implications of restrictions on individual rights and freedoms
Authors: Brașoveanu Florica
Published: December 2023

Restrictions on individual rights and freedoms may be justified by governments by the need to protect public safety and security. However, such restrictions can have negative implications for individual liberty and can restrict the fundamental rights of citizens, with a negative impact on social, economic and mental health. Governments must consider the impact of restrictions on society and individuals and strike a balance between protecting individual rights and freedoms and protecting public safety.
An Investigation on Wushu as the Main Cultural Symbol of China in Africa

Published: December 2023

This study investigates the claims that Chinese wushu is the main cultural symbol of the Chinese culture in Africa, highlights the communication processes of Chinese Wushu on the continent and probe into its localization and interaction with local cultures. The study relies on written documents from primary and secondary sources. Primary sources include libraries, specialized archives from some cultural institutions both located in China and Africa. Secondary sources include scientific journals and articles as well as official reports most of which are available online. Our research methods also include interviews, surveys, oral history and participant observation. As result of this investigation, the growing influence of Chinese Wushu through Kungfu Movies in Africa since the late 1970s following the emergence of Bruce Lee et al. has laid down the footprints of a China’s image and cultural identity to the African audiences, and therefore shaped their cognition of China through visual and bodies memories. In such a way that the Chinese Wushu has become the main cultural symbol of China in Africa. Meanwhile, the visual cognition of the Chinese Wushu has resulted to the creation of a “cultural gap” with regards to reality. Therefore, the main significance of this study, is not only to illustrate the existing cultural gap in the “Image Cognition” of China by Africans, but also to ascertain through facts that the Chinese wushu remain the main symbol of the Chinese culture in Africa and therefore an important window for African to visualized China.
