Authors: Mohammed Lina Y. 
Published: December 2023

The aim of this work is to synthesize zinc oxide (ZnO) nanoparticles from Eurca Sativa water extract which is a medicinal plant cultivated in home gardens in Kurdistan Region-Iraq. The biosynthesis of nanoparticles has been extensively studied due to their numerous applications. Among them, zinc oxide nanoparticles (ZnO NPs) have gained significant attention for wide range of its applications. To investigate the optical, chemical, structural, and morphological properties, different techniques; UV-VIS spectrophotometer, Fourier Transform Infrared Analysis (FT-IR), X-ray diffraction (XRD), Field emission scanning electron microscopy (FESEM), Energy-dispersive X-ray spectroscopy (EDX) were used.
The results revealed that typical ZnO absorption spectra exhibit a well-defined exciton band at 371.6 nm that is near the bulk exciton absorption of ZnO (373 nm) with an energy band gap of 3.029 eV, confirming the production of ZnO nanoparticles. FTIR study demonstrated the existence of bioactive compounds such as flavonoids, polyphenols, tannins, and saponins that can function as reducing and capping agents of ZnO nanoparticles. FESEM picture revealed that ZnO NPs show spherical morphologies with an average diameter of 71.07 nm. The antioxidant activities of biosynthetic ZnO NPs were studied using non-enzymatic methods; 2,2-diphenyl-1-picrylhydrazyl (DPPH), reducing power assay, and total antioxidant activities. The results showed that the biosynthesized ZnO-NPs nanoparticles had significant antioxidants compared with ascorbic acid as a reference. The obtained results showed that the present method is eco-friendly, less cost-effective, and safe for human health and this method plays a vital role in the industrial and biomedicine fields.

Published: December 2023

В статье рассматривается задача оценки пропускной способности Улан-Баторской железной дороги (УБЖД), которая является частью наиболее короткого транспортного коридора из Центральной России в Северо-Восточный Китай. Отличительной ее особенностью является то, что УБЖД в основном имеет однопутное сообщение, вследствие чего применяется пакетный график движения поездов, существенно усложняющий технологию работы. Исследование проводится методами математического моделирования с применением теории массового обслуживания. Модель имеет вид сети массового обслуживания, поступление пакетов поездов описывается при помощи BMAP-потоков, для учета различных маршрутов движения поездов используется несколько типов заявок. Выполняются численные расчеты, на их основе определяется текущая пропускная способность УБЖД и проводится сравнительная оценка эффективности возможных вариантов ее модернизации.
The article considers the problem of assessing the capacity of the Ulaanbaatar Railway, which is a part of the shortest transport corridor from Central Russia to Northeast China. In its current state, Mongolian railways cannot satisfy the growing demand for transit traffic, so the problem of increasing their capacity is essential. To find ways of solving this problem, we analyze the running of trains along the northern (most loaded) part of the trunk railway. Mathematical modelling based on the queuing theory is used as a research tool. The model has the form of a queuing network with 40 nodes, four BMAP flows, and four types of requests, for each of which a separate route matrix is constructed. The model describes the most significant properties of the Ulaanbaatar railway for the study, such as a single-track system of running, the arrival of train packages from several directions, the non-linear structure of the network, and the different routes of the train traffic. The mathematical model is implemented in the form of a simulation model and numerically studied. Based on the results obtained, we can draw the following conclusions. First, to meet the demand for container transportation in the short term, it is enough to increase the number of tracks at the sidings. Secondly, the complete reconstruction of the Ulaanbaatar Railway with the construction of double- track lines will allow bringing the railway corridor for passing through the territory of Mongolia. The major outcome is expected to be the volume of container transit among all land transport corridors between Russia and China. In addition to solving the important practical problem, the research results suggest that the presented highly adaptive model-algorithmic apparatus allows to studying a wide range of transport systems affected by random factors.

Published: December 2023

Для определения влияния изменения уровня оз. Байкал на экосистему его мелководной зоны и прибрежных территорий, а также нижнего бьефа Иркутской ГЭС потребовалось использовать модель прибрежного рельефа. В результате выполнения работы получена совмещенная модель прибрежного рельефа, по которой были построены зоны затопления. Для решения этой задачи разработаны и применены оригинальные алгоритмы обработки растровых пространственных данных и триангуляций.
The article discusses the experience gained while processing data on the relief of water bodies, such as the Irkutsk reservoir and the Angara River, for establishing a relief model that combines data from various sources, such as topographic and pilot maps, the results of depth measurements with an echo sounder, and the contours of coastal lines obtained from remote sensing data along with aerial photography. The use of algorithms developed for processing such data, which are based on the construction of triangulations, is considered. In addition to the actual algorithm for constructing the Delaunay triangulation with restrictions on vector data of various natures, algorithms have been implemented: removing triangulation artifacts built using relief isolines and morphing maps to coordinate the underwater part of the relief with the surface, replacing a triangulation fragment. The resulting relief model contains all the information about the relief of the studied area and allows it to be used for further hydrological calculations and analysis of the studied areas of reservoirs.

Published: December 2023

Anxiety is a psychological problem that is often experienced by individuals, especially when facing stressful situations. One of the anxiety disorders is generalized anxiety disorder (GAD). This disorder can be characterized by excessive worry about something. Mandala art therapy is an art therapy by coloring a circle shape that contains various geometric symbols. The circular shape of the mandala can help reduce anxiety. Several studies have shown that mandala art therapy is widely used to treat generalized anxiety disorder, especially in the adult age group. It’s necessary to have systematic literature to find how the therapy plays a role. However, there has been no literature review regarding the effectiveness of mandala art therapy on generalized anxiety disorder in the adult age group. The purpose of this study is to determine the effectiveness of mandala art therapy in reducing anxiety in adult individuals with generalized anxiety disorder. This study is a systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) protocol. The review was conducted using 12 journals determined through inclusion and exclusion criteria. The results obtained from the review show that mandala art therapy is effective in reducing anxiety in adult age groups. This is mainly because mandala art therapy combines art and therapy and has a therapeutic impact on generalized anxiety disorder in adults.Kecemasan merupakan masalah psikologi yang sering dialami oleh individu terutama dalam menghadapi situasi menekan.
