Authors: Vilhena Kleber , Rocha Carlos , Veiga Rafael , Bastos Lucas , Cerqueira Eduardo , Rosário Denis
Published: September 2024

O-RAN is an architecture that promotes interoperability and openness in 5G Radio Access Networks (RAN) using scheduling, disaggregation, and virtualization. RICs (RAN Intelligence Controllers) offer solutions such as Machine Learning (ML), traffic steering, anomaly detection, and QoS (Quality of Service) support. Novel intelligent handover strategies are critical to the success of 5G or even 6G O-RAN-based networks. This paper proposes and evaluates an intelligent handover algorithm for O-RAN environments. It leverages an LTE testbed featuring O-RAN architecture to assess downlink and uplink performance across various User Equipment (UE) scenarios. The proposed scheme was implemented and tested using ns-O-RAN, an O-RAN system integrated with the NS-3 simulator. Our simulator results demonstrate a throughput and delay enhancement compared to traditional handover methods across various scenarios involving 50 to 100 UEs.

Effective ways of learning social and political vocabulary in teaching Еnglish
Authors: Mammadova Aynur
Published: September 2024

The development of personnel potential, including the capacity to exhibit professionalism in different contexts, timings, and locations, is one of the most significant challenges facing universities offering specialized instruction in foreign languages. The article aims to provide students with a socio-political lexicon using contemporary learning ways and patterns of socio-political lexicon instruction in teaching English in higher education. The socio-political lexicon, which is well-known to have close ties to other fields of science and life, is a dictionary that covers the terms and concepts of the socio-political life of society. It is crucial to select innovative teaching techniques appropriate for various contexts when instructing students on sociopolitical vocabulary. Socio-political vocabulary must now be systematically taught to language faculty students in their specialized language using a planned, methodic, and progressive training model. It's essential that socio-political lectures are taught in English, which is the students' specialized language, and that modern teaching principles are being implemented. The socio-political lexicon is valuable for preparing students for job opportunities within the country and abroad. The research article offers insights on how to establish a strong foundation in political terminology. The open nature of the dictionary, book penetration, colloquial and shortened dictionaries, international terms, the existence of unique stable socio-political terminology, and the application of comparable techniques when translating from English to Azerbaijani or vice versa are some of the universal criteria of the socio-political lexicon. Furthermore, there are perceived deficiencies concerning the students' employment of socio-political jargon in their discourse. To achieve this goal, the research planned an experiment involving 26 students (15 girls and 6 boys) to analyze the issue. According to the findings, these problems were brought on by the students' involvement, the inadequate use of student-oriented learning environments, traditional approaches in vocabulary learning, the lack of rigorous application, and motivation, and the resistance to the notion of learning a second language.

Theoretical foundation of public administration in the sphere of water supply and water drainage
Authors: Slobodianyk Maksym
Published: September 2024

The sphere of water supply and drainage is a critically important component of the socio-economic mechanism, which is characterized by numerous challenges that were actualized in wartime. Aim of this paper is to analyze the main theoretical approaches of public management in the field of water supply and drainage in order to identify the main principles and tools that affect the efficiency and sustainability of the field. The tools of strategic planning, operational management and emergency response are considered as key components of successful management in this area. Emphasis is placed on the special role of developing fair tariff policies and financial support for infrastructure investments. The importance of the legal framework that regulates the sphere, ensuring compliance with environmental standards and protection of consumer rights is highlighted. The environmental aspect of resource management in the field, which includes modern methods of wastewater treatment and minimizing the negative impact on natural water bodies, is considered. It was emphasized that state intervention is a key factor in ensuring equal access to clean water, which is a basic human right according to the United Nations. The problem of natural monopoly in the field is considered through the prism of high capital investments and low elasticity of demand, which limit market competition. Strategies to stimulate competition and improve service quality are explored, including regulating tariffs and encouraging innovation. The example of Scotland, where water supply management is centralized through the creation of a single national company Scottish Water, reveals the effectiveness of such an approach in improving infrastructure and ensuring high quality services with public participation. The importance of a multidisciplinary approach to management in the field is emphasized, with a special emphasis on the stability of the service in wartime. The research may be useful to researchers, state and local authorities, and international organizations. Further perspectives of research include the study of the peculiarities of the application of the theoretical base in the solution of scientific and practical problems in the field in Ukraine during the war.

Authors: El-tayeb Moayad Mahgoub , KhamisKafi Shamson , H. Arbab Mohamed
Published: September 2024

Background: Herpes simplex virus (HSV) infection is one of the most common sexually transmitted infections. Due to its prevalence among women of reproductive age, the infection can be contracted during pregnancy and subsequently transmitted to the fetus or newborn. HSV is a significant cause of neonatal infections, which can result in death or long-term disabilities. The greatest risk of transmission to the fetus and newborn occurs when the mother contracts the initial infection in the second half of pregnancy. The risk of maternal-fetal-neonatal HSV transmission can be reduced through antiviral treatment or, in certain cases, by opting for a caesarean section. This research aims to determine the rate of HSV infection among pregnant women attending Saad Abou Ella Hospital, shedding light on the extent of the problem. Methodology: Blood samples were collected from 101 pregnant women under direct medical supervision via venipuncture using a 5 ml syringe. The blood was drawn into plain tubes, and serum was separated after centrifugation at 5000 rpm for 15 minutes. The sera were stored at -20°C until serological tests were conducted. Specimens were processed using a third-generation Enzyme-Linked Immunosorbent Assay (ELISA) (Foresight, Germany) to detect IgG antibodies against HSV-1 and HSV-2. Results: A total of 101 pregnant women participated in the study, with 45 from Khartoum, 25 from Omdurman, 9 from Bahri, 19 from Al Jazirah, and 3 from White Nile State. The participants' ages ranged from 16 to 41 years, with a mean age of 27.10 years. Most of the women were in the third trimester of pregnancy (67.7%) and had no history of abortion (80%). Among the 101 pregnant women studied, 32% were seropositive for HSV-1 IgG antibodies, and 17% were seropositive for HSV-2 IgG antibodies, with 5 women testing positive for both. The highest seropositivity for IgG was observed in the 32-38 age groups, among those with no history of abortion, and in women in the third trimester of pregnancy. Statistical analysis revealed no significant correlation (P-value > 0.05) between age, history of abortion, trimesters, and the frequency of HSV antibodies.

Authors: El Shaboury Nouran , Shamma Hamed M.
Published: September 2024

Recently companies started to use gamification in their businesses by applying techniques and concepts from games to their marketing strategies. Gamification concept can be applied to actual games, virtual trophies, points, and vouchers. The idea is that marketing strategies and activities that mirror games are better at engaging customers. Accordingly, it was important to study the relationship between gamification in marketing and consumer brand engagement in Egypt. Through reviewing the literature, there were several gamification components and mechanics such as points, badges, vouchers, progress bar, levels, leaderboards, social engagement, collecting resources, and competition between players. Different gamification frameworks have described the gamification elements. Gamification pyramid was the most common by many researchers. For consumer brand engagement, it was measured using three dimensions named cognition, emotional and behavioral dimensions. A descriptive study was conducted to examine the relationship between gamification elements and consumer brand engagement. Capitalizing on Gatautis et al. (2016) model, which studied the relationship between gamification elements and consumer brand engagement, a new modified framework, was introduced. Gamification elements were divided to four mechanisms named progress, rewards, social, and restrictions mechanisms. The research studied the relationship between each mechanism as an independent variable and consumer brand engagement as a multi-dimension’ dependent variable. Quantitative data was collected by distributing an online survey on 152 respondents through online channels. Data was analyzed using SPSS software, providing the reliability, descriptive, correlation and regression analysis. The analysis of the results showed that there is positive relationship between three of the gamification mechanisms and consumer brand engagement. While for the restrictions’ mechanism; it showed in-significant relationship. This research gives insights to managers and companies that would like to apply gamification, targeting its end users to increase their engagement towards the brand.

Authors: Dwivedi Sada Nand
Published: September 2024

An association analysis is an integral part of almost every clinical study. To determine the existing relationship of an exposure (e.g., smoking; treatment) with its expected respective outcome (e.g., coronary heart disease (CHD); improvement) accurately, one has to ensure the quality of data. Regardless of the types of association measures depending on various study designs (to be discussed separately), the association/relationship of exposure with an outcome may often get distorted due to the presence of various biases, including confounding and effect size modifications in the collected data. In spite of following each of the major research methodology steps required under a clinical study, to ensure the quality of data, one needs to minimize/nullify each of the numerous probable biases, including confounding and effect size modifications in the data. Hence, the focus of the present write-up is to briefly describe these biases so that researchers can be aware and take care of them in their clinical study.

Published: September 2024

Climatic and hydrological factors such as temperature, precipitation and flow play significant roles in shaping the physical and chemical characteristics of river water. This paper investigates the influence of these parameters on the water quality of the Tisa River in Serbia. Measurements were performed on a monthly basis, and the period 2008-2021 was analyzed. A correlation analysis was performed between each hydrological station (Martonoš, Novi Bečej and Titel) and the nearest meteorological station (Senta, Bečej and Zrenjanin). The variability of the following water quality parameters was analyzed: general parameters (pH and suspended solids), oxygen balance parameters (DO, BOD, COD, and total organic carbon), nutrients (nitrates, nitrites, orthophosphates, ammonium ions and total nitrogen) and salinity parameters (sulphates, chlorides and electrical conductivity) in relation to climatic (temperature and precipitation) and hydrological (fl ow) parameters in the Tisa River, section in Serbia. The obtained results clearly show that the climatic parameters and fl ow do not have a significant mutual relationship with the physical-chemical parameters that determine the water quality on the Tisa River. In other words, antropogenic action significantly reduced the quality of the Tisa River. Certain influences between climatic, hydrological and physico-chemical parameters are noticeable, and they are most expressed between flow and suspended materials (0.504), dissolved O2 and water and air temperature (-0.919), nutrients (NO3, NO2 and total N) and water and air temperature (0.795), as well as flow and chlorine (-0.539). Understanding these relationships is crucial for effective water resource management and environmental conservation eff orts. Through comprehensive analysis and data interpretation, this research aims to provide insights into the complex interactions between climatic and hydrologic variables and water quality parameters, contributing to the development of strategies for sustainable river ecosystem management. Continuous monitoring is also necessary to implement effective adaptation measures that promote the long-term sustainability of freshwater resources.

Published: September 2024

Suva Planina Mt. is a part of the Carpatho-Balkanides of Eastern Serbia. It encompasses the area of 427 km2, striking in NW-SE direction at the length of 43 km. Out of the total area of the mountain, limestones cover about 60%, mostly in the central part. The landform types include paleofluvial, fluvial, slope, as well as surface and underground Karst forms. The largest number of landforms are Karst dolines (1227 mapped), based on the official topographical map at the scale 1:25,000). Morphometric characteristics of doline-covered areas have been determined using the SRTM DEM (90 m resolution). According to the genetic classification, the dolines belong to the solution, collapse and suffosion types, while morphographically, they are funnel-like and bowl-like. Apart from these standard types, the "open" dolines, missing a part of their rims, are present as well. Regarding the spatial distribution, they are unevenly scattered. Hypsometrically, they are present from 480 and 1704 m a.s.l. The densities are in the span 1-21 per km2 (Valožje area). The main factors of spatial distribution are lithological composition, rock fractures and slope inclinations. The land cover mainly consists of woods and pastures, without intensive agricultural activities. According to the land use, the dolines on Suva planina are under forest cover and mountain pastures.

Published: September 2024

The discharge is the most important element of the water balance and is very important for the study of the variability of a particular watercourse because it represents the reaction of the entire river basin to changes caused by natural or anthropogenic factors. This paper aims to present statistical analyzes of discharge variability in the Morača river basin, up to the profile of the Zlatica hydrological station (42°29'01.64"N and 19°18'25.04"E), which covers the surface of 772.4 km2. The multi-year mean discharge values range from 27.4 m3/s at HS Pernica to 58.9 m3/s at HS Zlatica. Maximum discharges occur during November (Pernica Q=46.7 m3/s) and December (Zlatica Q=112.2 m3/s) and coincide with maximum precipitation in the basin, while secondary maximum occur during April (Zlatica Q =97.8 m3/s and Pernica Q=45.2 m3/s), as a consequence of the air temperature increasing and the snow cover melting on the high mountain areas. Minimum water occurs in August (5.5-7.1 m3/s). The statistical significance of the discharge trend was examined using the non-parametric Mann-Kendall test, and the trend's slope was determined using Sen's slope.. The analysis of the results shows a statistically significant negative change in discharge at HS Zlatica in the autumn season, as well as during October (at a significance level of 95%), while at HS Pernica monthly changes (February, March, September and October) were recorded at a level of low statistical significance (90%). Knowing the basic elements of river regimes variablity is a necessary prerequisite for the optimal and rational use of water resources, such as the Morača River. Therefore, the obtained results represent a good basis for all future water management planning and research.

The paper discusses the issue of professional development of geography teachers which involves changes in the existing concept of teacher's competences, starting from quality initial education of the teacher, continuous (formal and informal) education as well as self-evaluation and self-reflection about the teaching experience and the teacher's professional development, which create a unified system. Starting from the concept of education for sustainable development, as well as the changes caused by the implementation of this concept on the field of education, together with the results of research and practice, this paper revolves around the intention of pointing out differences between the condition of the initial education of a geography teacher and the teacher's professional development as well as the real needs of practice. The question of professional development of geography teachers, which represents the research problem of this paper, is analyzed through continuity in developing competences which are understood as the indicators of change in the existing practice, but also as a framework for development and establishment of a future model of education and professional improvement of teachers in the field of education for sustainable development. For this purpose, it has been concluded that it is necessary to invest further in the professional development of geography teachers as well as to create an efficient system of support for teachers, from the educational policy, the initial education of teachers to professional development.
Geographical science in the former Yugoslav territory and the congresses of the Slavic geographers and ethnographers (1924-1936)

Geographical science on the territory of former Yugoslavia began to develop at the end of the 19th century. In that period, the first geography departments and professional associations, as well as geographical societies, were established at the leading university centers. At the beginning of the 20th century, the first geographical journals were launched, among which the Bulletin of the Serbian Geographical Society (1912) has the longest tradition. However, numerous historical and political circumstances, primarily the First World War, stopped further progress in this field. Nevertheless, the end of the Great War, apart from the creation of a single state (the Kingdom of SCS), brought a new stage in the realization of teaching and scientific work. New tasks and roles of geography required the exchange of experiences and international cooperation. As a first step in that direction, the organization of the First Congress of the Slavic Geographers and Ethnographers in Prague in 1924 stands out. After the death of Jovan Cvijić, three more Congresses were held in Poland (1927), the Kingdom of Yugoslavia (1930), and the Kingdom of Bulgaria (1936). All the congresses, apart from their scientific value, also had socio-political significance expressed through the support of the official authorities. Therefore, this paper aims to analyze the participation and discourse of the representatives of the scientific community from the Kingdom of SCS (Yugoslavia) in the circumstances of the interwar period. The results showed that in the scientific work, the emphasis was on physical-geographic, cartographic, and ethnological research. At the same time, demographic research, as well as geo(political) and economic-geographic topics (agricultural, industrial, etc.) stemming from Cvijić's anthropogeographical school, were completely neglected. Despite numerous shortcomings, the mentioned meetings contributed to the unification of the scientific community and the promotion of geography in the Slavic countries. Also, they represented the starting point for new research and the organization of scientific work in the decades after the Second World War, both on the territory of Yugoslavia and in the wider international scientific community.

HERSCHEL-BULKLEY FLUID: STUDY OF RHEOLOGICAL PROPERTIES FOR BLOOD FLOW OF PULSES IN ω-PROTOTYPE IN ARTERIES’ STENOSIS
Authors: Pawan Kumar
Published: September 2024

In this article, we examined the blood flow that was being pressed as part of the war. The Herschel-Bulkley fluid model is applied for representing non-Newtonian blood features in the small arteries. The current governing equation is guided by the fact that the flow has shape and is linear. The standard method of cleanup is used to get first-order expressions for different flow variables. The temporal distributions of axial velocity and wall shear stress, flow meter flow rate and flow resistance are shown in bold. Also discussed are the parameters involved in the contact of various fields of impact plug-flow. A comparison of blood flow and stimulus signals in the same area also causes the blood vessels to recover.

EFFECT OF NICKEL NITRATE ON RENAL FUNCTIONS OF ALBINO RAT
Authors: Varsha  , Anand Pratap Singh
Published: September 2024

The purpose of this research was to investigate the absorption of nickel nitrate in rats using a renal approach at nickel concentrations of 400, 800, 1600, 3200, and 6400 mg/kg body weight using the renal technique. When nickel concentrations are less than 100 mg/kg body weight, active transport and facilitated diffusion play a critical role in the renal absorption of nickel. Because of saturation of the carriers at greater concentrations, the absorption rate would be reduced at higher concentrations. The distribution of nickel absorbed was investigated by the use of a 100 mg Ni/kg body weight solution administered over a period of 1 to 14 days. The liver is the organ that absorbs the most nickel nitrate, both in terms of concentration and quantity, followed by the kidney. It was discovered that 10% of the original concentration had crossed through the intestinal barrier after 14 days of collection when all of the collected organs (renal function) and blood were tested, but not the liver, after 14 days of collection..
Reliability Allocation Method for Lightweight Propulsion System of Electric Aircraft

Published: September 2024

Aiming at the contradiction between lightweight and high reliability of electric propulsion system of electric aircraft, a reliability allocation method considering lightweight constraint is proposed for the first time. The analytical expression between weight and reliability is constructed, and the uncertainty of the operating conditions of electric aircraft is considered with this as constraint. A "weight-reliability" multi-scenario balanced optimization method based on typical flight profile is proposed, which achieves the lightest weight under reliability constraint and the highest reliability under weight constraint. Taking the "Spirit of Innovation" electric aircraft as an example, the method proposed in this paper can reduce the total weight of the electric aircraft propulsion system by 3.5% by allocating the reliability of each subsystem while ensuring the reliability of the system. The effectiveness of the proposed method is verified by designing different scenarios, providing technical support for the development of high power-to-weight ratio of electric aircraft.

Published: September 2024

In order to solve the multi-objective optimization problem (MOP: Multi-Objective Problem), the artificial bee colony algorithm (ABC) has the problems of difficulty in collecting and maintaining the diversity of candidate solutions. The solution strategies of each part are improved. Based on the ABC algorithm framework, a multi-objective ABC algorithm based on adaptive solution strategy is designed. The proposed improved multi-objective ABC is compared with other typical swarm intelligence algorithms in the practical application engineering design problem of electromechanical actuator design. Experimental verification shows that the proposed MOABC/DD (Multi-Objective Artificial Bee Colony Based on Dominance and Decomposition) algorithm has better problem solving accuracy than typical algorithms when solving the benchmark test case of electromechanical actuator design problem. In addition, the experimental results of MOABC/DD are relatively stable, which proves that MOABC/DD has high solution stability and robustness. Keywords: multi-objective optimization problem.
