Symmetrized Versions of the Seidel and Successive OverRelaxation Methods for Solving Two-Dimensional Difference Problems of Elliptic Type
Authors: Sidoryakina V. V. , Solomakha D. A. 
Published: October 2023

Introduction. This article is devoted to the consideration of options for symmetrization of two-layer implicit iterative methods for solving grid equations that arise when approximating boundary value problems for two-dimensional elliptic equations. These equations are included in the formulation of many problems of hydrodynamics, hydrobiology of aquatic systems, etc. Grid equations for these problems are characterized by a large number of unknowns — from 106 to 1010, which leads to poor conditionality of the corresponding system of algebraic equations and, as a consequence, to a significant increase in the number of iterations, necessary to achieve the specified accuracy. The article discusses a method for reducing the number of iterations for relatively simple methods for solving grid equations, based on the procedure of symmetrized traversal of the grid region.Materials and Methods. The methods for solving grid equations discussed in the article are based on the procedure of symmetrized traversal along the rows (or columns) of the grid area.Results. Numerical experiments have been performed for a model problem — the Dirichlet difference problem for the Poisson equation, which demonstrate a reduction in the number of iterations compared to the basic algorithms of these methods.Discussion and Conclusions. This work has practical significance. The developed software allows it to be used to solve specific physical problems, including as an element of a software package.

Abstract

OBJECTIVE
Nutrition is important in preventing and managing disease. Veterinarians are an important source of nutrition information; however, nutrition communication between veterinarians and pet owners is relatively infrequent. The purpose of this study was to conduct a qualitative review of barriers to nutrition communication and possible solutions, reported by small animal veterinarians.

SAMPLE
18 veterinarians from Maryland, Michigan, Virginia, Washington DC, and West Virginia.

METHODS
In a qualitative focus group study, 5 virtual focus groups using the Zoom platform were conducted from February 3, 2021, to April 2, 2021. Each focus group was audio recorded, and transcripts were created using Otter.ai software. Transcripts were analyzed in Atlas.ti qualitative data analysis software using a hybrid of inductive and deductive thematic analysis.

RESULTS
The 4 barriers to nutrition communication identified by veterinarians were as follows: (1) time, (2) misinformation and information overload, (3) pet owners’ apprehension toward new information, and (4) veterinarians’ confidence in nutrition knowledge and communication skills. Potential solutions include (1) improving communication and nutrition education, (2) improving and increasing access to client-friendly resources, and (3) empowering credentialed veterinary technicians and support staff to discuss nutrition.

CLINICAL RELEVANCE
This study provides guidance for how to focus efforts to break down barriers to nutrition communication in small animal veterinary practice.

ABSTRACT

Morchella fluvialis, a morel mushroom, is one of the most famous edible mushrooms all over the world. Interest in this mushroom is steadily increasing due to its organoleptic properties and nutritional value. The methanolic extract of M. fluvialis showed α-glucosidase inhibitory and antioxidant activities in an assay system. Therefore, the purification and characterisation of bioactive metabolites and evaluation of biological activity were conducted. Fractionation of the M. fluvialis extract resulted in the isolation of nine compounds, namely, three fatty acids, (9Z,12Z)-octadecadienoic acid (linoleic acid, 1), (9Z,12Z)-3-hydroxyoctadecadienoic acid (2) and (6Z,9Z)-13-hydroxyoctadecadienoic acid (3); four sterols, stellasterol (4), ergosterol peroxide (5), ergosterol (6) and brassicasterol (7); one sugar alcohol, arabitol (8); and nicotinamide (9). Among them, compounds 2–3 and 7 were first reported from Morchella. In addition, compound 1 exhibited potent α-glucosidase inhibition, with an IC50 value of 14.8 μM. The content of compound 1, the major compound, was 1.2 mg · g–1 extract, as quantitated by HPLC analysis, which was lower than the IC50 value of compound 1. Therefore, M. fluvialis can benefit from diabetes and related diseases through the synergistic effect of linoleic acid (1) and other ingredients.
Risk assesment as a stage of risk management in enterprise in tourism sector
Authors: Nedyalkova Plamena 
Published: October 2023

AbstractRisk management is a complex process that requires company managers to have very good knowledge of its organizational structure on the one hand and on the other hand, in order to achieve a good management, it is necessary for the respective manager to have sufficient long-term experience during which the manager has monitored the processes of company management and its susceptibility and change under the influence of various factors. The overall risk management process goes through three main stages: identification of risks, analysis and assessment of risks and risk monitoring. Each stage is a compilation of complex procedures through which the problems and risks for the respective enterprise are determined and overcome. For this reason, the strictness, importance and significance of each stage cannot be accurately determined. Due to the limited scope of the article, the research is focused only on one of the main problems in risk management, namely the study of the standard deviation of the risk in the process of assessing and analyzing the risks in tourism sector enterprises. The article has the following structure: Introduction, References review, Methodology, Results and Discussion. Two hypotheses are presented for testing and research. Proving these two hypotheses through the application of the mathematical toolkit for risk assessment gives the innovativeness of the article and its authorial identity, which distinguishes it from other publications in the field of tourism sector. The obtained results of this article can serve the managers of tourism companies to improve their work in the management of hotels. The process of identifying, testing, evaluating and analyzing risks is complex, requiring managers to have sound knowledge of finance, accounting, economics and management. This article can provide them with guidance for solving specific problems and making managerial decisions about risk management.
An assessment of the risk mitigating factors in Ghana’s Bank Industry
Authors: Alnaa Samuel Erasmus , Matey Juabin 
Published: October 2023

Abstract
To maintain financial stability, banks need to recognize, assess, and mitigate potential losses, thus making risk control critical for long-term profitability as well as avoiding unexpected losses. This research examines the risk mitigating factors and performance of Ghanaian domestic banks in terms of capital adequacy, bank size, bank efficiency, and profitability, along with their association with systemic risk in the bank sector, as measured by the Z-score: Insolvency Risk - (µROA) plus capital asset ratio (equity capital divided by sum of all assets further divided by the standard deviation-(ƠROA) with a higher score for banks as a measure of bank stability. The study further explores the relationship between this ratio and the explanatory variables for a sample of 11 banks operating in Ghana between 2010 and 2021. Analysis of the data using the fixed effects model shows that profitability and bank efficiency are significant and affect the stability of banks positively. Bank size, on the other hand, is significant but negatively affects the stability of banks. Bank profitability is critical to stabilizing and protecting the banking sector from external shocks; as a result, this study suggests that bank management apply prudent practices to profitability-driven indicators and that the banking sector regulations be congruent with macro-prudential policies.

Published: October 2023

Abstract
The article discusses the mechanical properties of glass fiber epoxy composites with three types of textile structures. Braided, knitted and woven sleeves were placed on a 3D printed flat core and impregnated with resin using the vacuum bag method. The 3-point flexural and tensile tests were performed. The results were compared with those of 3D-printed flat bars and proved that woven textile structures increase the strength and modulus of elasticity, whereas braided and knitted structures only increase the moduli. The advantages, drawbacks and failure modes of each reinforcement structure are also discussed including the drapeability on the spatial core.

Abstract
Analysis of the impacts of real estate development on biodiversity within the confines of Imo State, Nigeria, was the main objective of this study. The investigation included a look at how land use and land cover (LULC) changed between 2017 and 2022. The study made use of Sentinel-2 image with a spatial resolution of 10 m. The research team used supervised classification algorithms to classify the imagery, which were then compared to find changes in land use and land cover (LULC). The following categories apply to the land use and land cover (LULC) of the study area: In 2017, trees accounted for 58.84 % of the total land surface and covered the most land, covering an area of 315.05 km2. The amount of developed land, or 30.23 % of the total land area, was assessed to be 161.84 km2. Approximately 61.91 % of the entire land surface in 2018, or 331.47 km2, was covered by arboreal vegetation, which dominated the landscape. Comparatively, urbanised regions made up 177.41 km2, or 33.14 % of the total land area. With trees making up 59.434 % or 318.22 km2 of the total land area in 2019, trees were found to be the most prevalent kind of land cover. Concurrently, built-up areas accounted for 34.30 % of the land, or 183.66 km2. The LULC map for 2020 showed a comparable pattern, with trees covering 58.46 % (equivalent to 313.02 km2) of the total land area and built-up areas covering 34.71 % (equivalent to 185.88 km2). According to the research, the impact of real estate development on the environment is primarily negative, resulting in habitat depletion, ecosystem fragmentation, and the introduction of pollutants. The researchers advised using sustainable development practises to mitigate the aforementioned negative effects.
Identification of the spatial extent of the peri-urban area: The case of three cities in Poland
Authors: Bański Jerzy , Mazurek Damian 
Published: October 2023

Abstract
The work detailed here seeks to recognise features by which areas that can be deemed peri-urban differ from both city and countryside, to the extent that a separate specific identity for them can be discerned. The recognised features made it possible to identify the extent of the peri-urban area. The wealth of relevant literature is first considered, and this is seen to relate to the spatial side and to definition on the one hand, and to ongoing socio-economic processes on the other. Several Polish cities are then selected as the authors seek to discuss indicators useful in determining the spatial scope of the said peri-urban zones. The work proceeds on the assumption that these represent a real component of an urban-rural continuum characterised by reduced diversity and intensity of social and economic phenomena with steadily-increasing distance from the limits of a city in the direction of “traditional” rural areas.
Impact of expansion joints on noise pollution, case study in Cluj-Napoca
Authors: Marusceac Vladimir , Danciu Alexandra Denisa 
Published: October 2023

Abstract
The aim of this paper is to study the impact that certain types of expansion joints have on noise levels produced by regular traffic on the streets of Cluj-Napoca. The study was carried out on three distinct locations, all three road bridges had steel expansion joints, the first one had asphalt covering the joints, the second one was in excellent condition, as it was a newly refurbished bridge and the last one with visible signs of degradations.
After a full spectrum noise analysis, the results showed that good maintenance and quality control on the installation of expansion joints are necessary, not only to lower noise levels but to also provide a solid and sealed transition to the bridge deck.

Published: October 2023

AbstractThe paper highlights the contribution of the road traffic to PM2.5air pollution, taking in consideration the atmospheric parameters. But, despite other studies, temperature and relative humidity are considered as moderating variable. The concentration of particulate matter is also influenced by local geography, urban structure, and streets shape. The case study was done in Bucharest, in an open area. The PM2.5air concentration time series is proved stationary, an autoregressive model with two lags being tested. While the main effects of road traffic and humidity are significant, temperature has not a significant direct effect. But both moderators show interactive effects. The conditional effects are getting down with increase in temperature and humidity, due to changes in air dynamics and precipitation phenomena.

Published: October 2023

Abstract
This paper discusses the recycling of glass waste as a compound in the production of ceramic tiles. The present study aims to investigate the effects of glass waste (with two different granulometries) on the physical and mechanical properties of ceramic tiles, in order to demonstrate their suitability for the production of ceramic materials. A series of ceramic tiles was prepared based on bentonite (B) by adding 70, 65, and 60 wt% glass wastes (GW1 and GW2 with two different granulometries) into the batch composition. The ceramic tiles were sintered at a constant temperature of 900 °C following the same production protocol. The physical-mechanical properties and chemical durability of all ceramic tiles produced were evaluated. The results show that ceramic tiles can be produced from a basic mixture of 35% bentonite and 65% glass waste, with good physical, mechanical, and thermal properties (the local Algerian bentonite is considered a clay binder and has excellent plasticity).

Published: October 2023

Abstract
This study investigates the conventional and Islamic equity market reaction towards terrorism events in Pakistan from 2009 to 2016 using OLS regression and GARCH (1, 1) models. The prospect theory and efficient market hypothesis are the relevant theories. Findings indicate that conventional and Islamic equity market reaction towards terrorism events is very short lived and markets recovers quickly. This study also documents the market reaction to terrorism events based on the target type, location and during the Islamic calendar months. The impact of different target types and different event locations on the conventional and Islamic equity markets varies. The equity markets in Pakistan responds negatively to the attacks on educational institutes and businesses whereas positively to attacks on armed forces’ facilities. Furthermore, conventional equity market responds negatively to terrorist attacks in Karachi and positively to attacks in financial cities and FATA. Interestingly, Islamic equity market responds positively towards the attacks in financial cities and FATA, however, with very minute reaction magnitude. The findings of this study are useful for the investors to manage their portfolios by considering magnitude and direction of market reaction towards terrorism based on the target type, location and Islamic months. Overall, this study concludes that conventional and Islamic equity markets reaction towards terrorism is very minute; however, the conventional and Islamic equity markets reaction varies based on target type, event location and different Islamic calendar months. Furthermore, the findings also suggest that equity markets recover very soon, therefore, markets are efficient in observing these shocks.

Published: October 2023

Deixis, the linguistic phenomenon of words pointing to specific entities in discourse or situational context, has been explored in various forms of expressive arts. One interesting example of deixis in expressive arts is the use of deixis in song lyrics. In this present study, Gayonese local songs from Aceh, Indonesia, in the Kupi Gayo album by Ervan Ceh Kul, are studied by examining the deictic terms he used to construct the cultural context of ten songs. For this goal, the descriptive qualitative method was used to analyze the songs’ deixis using the framework of Grundy (2000). The results revealed that the songwriter used more first and second personal deictic terms, suggesting that he tried to add a layer of emotional connection between the artist and the listeners, allowing for a more immersive and relatable musical experience. Nevertheless, he used place and temporal deixis less frequently, indicating that he tried to create rich and immersive experiences for the listeners. The results showed that using deictic terms in the vernacular language facilitates effective communication and understanding within a specific community or culture. By understanding the function and purpose of deixis in the vernacular language, researchers and linguists can gain insights into how individuals in a society navigate their social interactions.

Published: October 2023

Objectives:
This study based on an epidemiological registry aimed to characterize the clinical, epidemiological presentation and impact of atopic dermatitis on the quality of life (QoL) of teenagers and adult patients treated at the outpatient clinic of Atopic Tertiary Referral Hospital in Brazil.

Material and Methods:
Ambidirectional study, with prospective and retrospective data collection of patients, aged ≥13 years, diagnosed with AD. Sociodemographic, clinical information, and immunoglobulin E (IgE) levels were obtained using a specific protocol, as well as assessment of QoL using the psychosomatic scale for atopic dermatitis (AD) (PSS-AD) questionnaire.

Results:
Seventy patients were enrolled, 43 (61.4%) were female and 54 (77.1%) were ≥18 year. The mean age of AD patients was 29.2 years (standard deviation ± 15.5). Most AD symptom associates were itching (100%) followed by insomnia (74.3%). Emotional distress was the most frequently self-reported AD triggering factor (90%). With this study, we have demonstrated that AD type 2 inflammation (97.1%) was most common, which is characterized by high IgE levels. Moreover, 44.3% and 45.7% of patients evaluated by the scoring atopic dermatitis index score, had severe and moderate disease respectively. The PSS-AD questionnaire showed negative mental health impact in AD patients.

Conclusion:
Adults and teenagers (≥ 13 years) with persistent AD need global management, including psychological and mental health support.

Published: October 2023

Background
Rodent-borne viruses such as orthohantaviruses and arenaviruses cause considerable disease burden with regional and temporal differences in incidence and clinical awareness. Therefore, it is important to regularly evaluate laboratory diagnostic capabilities, e.g. by external quality assessments (EQA).

Aim
We wished to evaluate the performance and diagnostic capability of European expert laboratories to detect orthohantaviruses and lymphocytic choriomeningitis virus (LCMV) and human antibody response towards orthohantaviruses.

Methods
We conducted an EQA in 2021; molecular panels consisted of 12 samples, including different orthohantaviruses (Seoul, Dobrava-Belgrade (DOBV), Puumala (PUUV) and Hantaan orthohantavirus), LCMV and negative controls. Serological panels consisted of six human serum samples reactive to PUUV, DOBV or negative to orthohantaviruses. The EQA was sent to 25 laboratories in 20 countries.

Results
The accuracy of molecular detection of orthohantaviruses varied (50‒67%, average 62%) among 16 participating laboratories, while LCMV samples were successfully detected in all 11 participating laboratories (91-100%, average 96%). The accuracy of serological diagnosis of acute and past orthohantavirus infections was on average 95% among 20 participating laboratories and 82% in 19 laboratories, respectively. A variety of methods was used, with predominance of in-house assays for molecular tests, and commercial assays for serological ones.

Conclusion
Serology, the most common tool to diagnose acute orthohantavirus infections, had a high accuracy in this EQA. The molecular detection of orthohantaviruses needs improvement while LCMV detection (performed in fewer laboratories) had 95% accuracy. Further EQAs are recommended to be performed periodically to monitor improvements and challenges in the diagnostics of rodent–borne diseases.
