Published: October 2024

Background: Alcohol use, even in moderation, causes hangover discomforts. It has been reported that alcohol-associated symptoms can be improved by either probiotics or medicinal plant extracts to some extent. However, the effects of a combination of multi-strain probiotics, prebiotic, and plant extracts have not been fully explored.
Objective: Our main goal is to assess behavioral responses and alcohol metabolism in zebrafish treated with a combination of multi-strain probiotics, prebiotic, and plant extracts after ethanol administration.
Methods: In this study, the zebrafish were first treated with the probiotic-prebiotic-plant extract mixture, and then was exposed to different levels of ethanol. The moving distance and activities of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) of zebrafish were measured after ethanol treatment.
Results: This probiotic-prebiotic-plant extract mixture significantly improved total distance moved and activities of ADH and ALDH in zebrafish treated with either 1.5% or 4.0% ethanol. In particular, the mixture outperformed plant extracts (both at 250μg/mL) in total distance moved under 1.5% ethanol administration and degrading acetaldehyde under 4.0% ethanol treatment.
Conclusion: A combination of probiotics, prebiotic, and plant extracts effectively mitigated hangover symptoms in cases of moderate and heavy alcohol use and demonstrated superior performance in acetaldehyde metabolism compared to plant extracts alone after heavy drinking, based on a zebrafish model.
Keywords: probiotic, prebiotic, Hovenia dulcis, kudzu root, curcumin, ethanol, hangover, behavior, metabolism, zebrafish.
The Impact of Cash Liquidity and Financial Leverage on The Performance of Iraqi Banks: A Comparative Study Between Islamic and Conventional Banks
Authors: Tareq Saeed Al-Aaraji* Sebyan 
Published: October 2024

Degree of financial leverage refers to the percentage of bank assets financed through debt, which banks must employ to achieve returns and cover costs, as well as the availability of cash at maturity. Therefore, the problem of the study arises in how the indicators of leverage and cash liquidity affect the indicators of financial performance in the Iraqi banking sector. That is why the study aims to use econometrics to demonstrate the impact of leverage and cash liquidity on the financial performance indicators represented by return on assets (ROA) and net profit margin (NPM) for a sample of 38 conventional and Islamic banks for the period 2010-2022. The Dynamic Panel Data methodology was used to determine the relationship between variables, which combines time series and cross-sectional, precisely the generalized moment method (GMM). Results show that financial leverage negatively and significantly impacts ROA and NPM indicators in the total sample and Islamic and conventional banks, except for the positive relationship with ROA in conventional banks. The results also showed the positive impact of cash liquidity on ROA and NPM indicators in the total sample and Islamic and conventional banks, except for its negative impact on ROA indicators in conventional banks. The results also showed the negative impact of the cash credit (cash credit to total assets ratio) on ROA and NPM indicators in the total sample and Islamic and conventional banks.

Authors: Imran Musa * Salman , Kareem Brehy Faris 
Published: October 2024

Maximizing the effectiveness of the agricultural investment environment for all its basic inputs from the economic and human resources available in Iraq represents a qualitative breakthrough in the production of strategic crops, therefore, the research problem came from the weak production of strategic agricultural crops in Iraq in quantity and quality, due to the ineffectiveness of the agricultural investment environment, as a result of the lack of government support, the deterioration of the infrastructure of the agricultural sector, and a shortage of monetary capital, Finally, the scarcity of water resources, the problem was treated using the analytical method, thus, the research aims to demonstrate the importance of developing the agricultural investment environment and increasing government support and its impact on the production of strategic agricultural crops, the research concluded that Iraq possesses most of the basic inputs to the agricultural investment environment, but it lacks efficient management and optimal use, in addition to climate change, which has helped increase drought and desertification, the research also concluded that agricultural policy in Iraq includes obliging the investor to an agricultural plan in which the cultivated area is determined under the pretext of limited the capacity of the stores and the amount of strategic water storage despite Iraq’s need for strategic crops and thus the state’s attempt to meet the increasing demand for strategic crops t-hrough imports, which makes Iraq subject to the fluctuations of the global market and the depletion of hard currency, the researcher recommends efficient and optimal exploitation of natural, financial and human resources and keeping pace with scientific and technological progress in the production of strategic crops. In conclusion, the research included the deductive approach through the method of analytical description to advance the agricultural investment environment in Iraq.

Comparison between estimates of beta regression model using MSE
Authors: Dheyaa Ismaiel Melad , Dheyab Ahmed Ahmed 
Published: October 2024

The multiple linear regression analysis shows the effects of explanatory variables on the dependent variable. Its function is to represent data to understand the shape and nature of the relationship between explanatory variables and the response variable. One of the main problems faced by linear regression is the nature of the data, as sometimes it does not follow a normal distribution. This has led to the emergence of different types of linear regression models such as the beta regression model, where the data of the dependent variable is less than one and confined within the period (0,1), and the data is relative and decimal. Non-traditional methods will be used to estimate beta regression parameters because some traditional methods do not provide suitable and accurate results when dealing with one of the main problems encountered in regression, which is multicollinearity. To address this issue, we used some methods include The Maximum Likelihood Estimation (MLE), ridge regression, modified Liu, and Ozkale and Kaciranlar method. Shrinking parameters are proposed for each method, and a comparison between the methods is conducted using the Mean Squared Error comparison criterion through a simulation experiment with two approaches, the simulation results showed that the ridge regression method is the best for the first and second methods of simulation.

Authors: Jamal Mohammed* Ahmed , M. Alwan Faris 
Published: October 2024

This study investigates to shed light on artificial intelligence techniques, specifically the genetic algorithm, to improving traditional solutions, as well as finding the best policy for the problem of probabilistic inventory with continuous review by finding the optimal reorder point and the optimal economic quantity to avoid the risk of stock out (shortage), reduce total costs, and reach the optimal solution with little time and effort. The research was conducted in the stores of the department of pharmacy of the Ninawa health department for the period from January 1, 2021, to January 1, 2023, on a sample of three drugs (most demanded drugs). An analysis of the demand data for the study sample was conducted using the statistical program (SPSS Statistics Version 22) to determine the type of inventory. it was found that the type of inventory is probabilistic and the demand data follows a normal distribution. Based on this foundation, the mathematical model for the study problem was built. Given the complexity of the steps and iterations of the traditional solution, the solution steps were applied using the R programming language to reach the model's solution. Additionally, the solution steps were programmed for the genetic algorithm and applied using the R programming language. The results of the genetic algorithm showed an improvement in the traditional solution results by reducing total costs. Based on the results of the genetic algorithm, the economic order quantity, safety stock, reorder period, and safety period were found.

СТАРОВИННІ НОТОЛІНІЙНІ ІРМОЛОГІОНИ XVII – XVIII ст. У СУЧАСНИХ ДНІПРОВСЬКИХ АРХІВАХ: ОПИС РУКОПИСНИХ ДЖЕРЕЛ
Authors: Hromchenko Natalia 
Published: October 2024

Метою статті є аналіз старовинних нотолінійних Ірмологіонів XVII – XVIII століть, що зберігаються в сучасних архівах Дніпровського національного історичного музею імені Дмитра Яворницького (м. Дніпро). У ряді методів дослідження відзначимо передусім джерелознавчий, аксіологічний, історичний, музично-теоретичний, а також структурно-функціональний та методи аналізу і синтезу. Новизна статті обумовлюється насамперед введенням до сучасного музикознавчого обігу музично-історичних пам’яток українського гімнографічного мистецтва, що до цього часу не ставали матеріалом наукових досліджень мистецтвознавців, як у вітчизняних, так і закордонних науково-дослідницьких розвідках. Актуальність презентованої теми дослідження полягає в тому, що в українському музикознавстві вперше описуються нотолінійні Ірмолої XVII – XVIII століть із сучасних дніпровських архівів, як унікальна музично-історична пам’ятка гімнографічного мистецтва. Висновки. Ознайомлення з нотолінійними Ірмолоями, що зберіглися в сучасних архівах Дніпровського національного історичного музею імені Дмитра Яворницького (м. Дніпро), дає можливість стверджувати, що аналізовані Ірмолої були створені (написані) у ХVІІІ столітті. Вони дають нам унікальну можливість ознайомитися із певними особливостями богослужбової практики того часу. Так, в Ірмолоях маємо ноти сидальних після кафізм. Наголосимо, що у сучасній богослужбовій практиці їх не співають, тобто на сьогодні ця частина богослужбового репертуару вилучена із співацького ужитку. В Ірмолої № 1424 в останньому розділі, поряд із текстами тропарів, кондаків та богородичних, що на сьогодні, підкреслимо, співають у кожному храмі, виписані також іпакої на вісім гласів. Таким чином, маємо зробити наступне припущення, що вони мали бути обов’язковими для тогочасного богослужбового співу.

Мета статті – створити, вперше у вітчизняному музикознавстві, періодизацію життєтворчості визначного диригента, педагога і просвітителя Анатолія Калабухіна для визначення етапів його професійного зростання і виявлення чинників, що сприяли вершинним досягненням маестро у фазі акме. Методологія базується на застосуванні системного підходу з поєднанням історико-контекстуального, біографічного, феноменологічного та акмеоцентричного методів, застосованих задля усвідомлення довершених здобутків А. Калабухіна у контексті еволюції художнього мислення митця. Наукова новизна полягає в тому, що в даному дослідженні вперше у вітчизняному музикознавстві створена періодизація життєтворчості визначного українського митця А. Калабухіна. Висновки. Підсумком аналізу життєтворчості А. Калабухіна є створення її періодизації відповідно до біографічного, географічного, вікового та еволюційно-виконавського критеріїв. Встановлено, що керування А. Калабухіним на різних етапах його творчо-виконавської діяльності харківськими колективами: симфонічним оркестром філармонії, національним академічним театром опери та балету імені М. Лисенка та оперною студією національного університету мистецтв ім. І.П. Котляревського віддзеркалюють зміни в розбудові професійного шляху визначного митця. Чотири періоди життєтворчості Анатолія Калабухіна є відображенням еволюційних процесів у творчій долі як диригента-інтерпретатора, педагога й просвітителя. Четвертий період, що є кульмінаційною зоною життєтворчості митця, розподілений на три етапи, що пов’язані з діяльністю маестро в трьох мистецьких закладах Харкова, де останній період – керування оперною студією університету (1979 – 2022), визначений як фаза акме, коли його майстерність сягнула найвищого рівня.
