This review article summarizes current research from 2019 to 2024 with an emphasis on the kinds of datasets, timeframes, and models used. The examination displays a wide range of data, from the 1970s to 2022, with the majority of studies depending on data collected after the 1990s because of its increased dependability and availability. Many models have been used, such as Markov switching models, artificial neural networks (ANN), signal approaches, deep neural decision trees (DNDTs), and traditional econometric models like logit and probit. The results emphasize that there isn't a single model that is always better; rather, they emphasize the significance of choosing models based on context and the advantages that hybrid or ensemble approaches may have. Our review highlights that to improve prediction accuracy, a variety of datasets and models must be used. Because currency crises are inherently complex, a multifaceted strategy that makes use of both conventional econometric and contemporary machine learning techniques is required. To better capture the complex dynamics of economic indicators, future research should investigate higher frequency data and keep improving hybrid methodologies. This thorough analysis contributes to the current discussion on currency and financial crisis forecasting by offering insightful analysis and directing future research paths.</p> Haitham Assi Kareem, Idress Mohammed Husien Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1210 Sat, 22 Mar 2025 00:00:00 +0100 Polyphenols of Mulberry White (Morus alba L.) Leaves as a Source of Functional Food: A Review https://isnra.net/ojs/index.php/kjps/article/view/1243 <p>Mulberry is a plant that grows in temperate to subtropical climates. Mulberry leaves are economically feasible due to their historical importance in sericulture, so their production increases yearly, but the large output leads to a large percentage of residues. As a result, it was largely accumulated, creating controversial consequences, rather than being reintegrated into the manufacturing process for a new function. However, this residue in mulberry leaves naturally contains high levels of bioactive compounds, especially polyphenols. Mulberry leaves have a vital pharmaceutical potential role as antibacterial and antioxidant. Mulberry leaves have many health benefits, such as anticancer, antiviral, and anti-obesity etc. However, many extraction methods can benefit different uses as food innovation, leading to added-value products. So, the current review article provides a comprehensive discussion concerning extraction methods, metabolism, health effects such as Anticancer, Antidiabetic<strong>,</strong> Anti-obesity, Activity of anticonvulsant, Antiatherosclerosis, and SARS-CoV-2 inhibition, and various uses in the food industry.</p> Hagar F.

It is a double-strand DNA virus enclosed in an envelope and a member of the Orthopoxvirus genus within the Orthopoxviridae family. This disease was spread in West and Central African countries and other regions as well. It transmits through direct contact with the skin lesions of an infected person, as well as through respiratory droplets and contaminated materials. Monkeypox is generally less severe than smallpox, and most people recover completely from it; however, it is still serious, especially for young children, pregnant women, and people with weakened immune systems<strong>.</strong> It causes pain, fever, rash, and swollen lymph nodes.</p> Huda Mawlood Taher, Hiyam Jamal Ibrahim, Bayan Mohammed Mahdi Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1255 Fri, 02 May 2025 00:00:00 +0200 An Investigation of the Magnetic and Structural Characteristics of Li-Ni ferrite nanoparticles https://isnra.net/ojs/index.php/kjps/article/view/1287 <p>Nanoparticles of Li-Ni ferrite (LiNi₀.₅Fe₂O₄) were synthesized through the sol-gel auto combustion method, employing lithium nitrate, nickel nitrate, and ferric nitrate as precursors, with citric acid acting as a chelating agent. The samples were annealed at temperatures (as-burnt, from 400 to 800 °C). The impact of various calcination temperatures on the crystalline structure and magnetic characteristics of the LiNi₀.₅Fe₂O₄ nanoparticles was meticulously investigated through X-ray diffraction (XRD) and a vibrating sample magnetometer (VSM).</p> <p>From XRD analysis, crystallite size D determined for the most intense (311) peak using Scherrer’s formula. An increase in crystallite size was observed with higher annealing temperatures in the range of 28.50-41.345 nm, while coercivity with range 47.9-154.5 Oe showed an initial rise before decreasing as crystallite size grew. Variations in saturation magnetization (range 6.23-8.02 emu/g) and 1attice constant (range 8.291-8.295 °A) displayed a similar trend, decreasing at 400 °C and 600 °C but increasing at 800 °C.</p> Ebtihal Khidher Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1287 Sun, 13 Apr 2025 00:00:00 +0200 Assessing the Radioactivity of Samples Taken during a Dust Storm in the Iraqi City of Hilla https://isnra.net/ojs/index.php/kjps/article/view/1235 <p>The research aims to investigate the distinguishing behaviors and risk indicators in samples of dust storms in Hilla city, Iraq. NaI (Tl) detector was used for the measurements, along with spectrum analysis. The findings of the measurements of elements <sup>238</sup>U, <sup>232</sup>Th, and <sup>40</sup>K's specific activities in samples from dust storms ranged for <sup>238</sup>U from 9.2 ± 0.5 to 22.9 ± 0.8 (Bq/kg) at an average 16.92 ± 0.7 (Bq/kg), the range of <sup>232</sup>Th's specific activity was between 2.7 ± 0.2 to 11.41 ± 0.5 at the average6.5 ± 0.3 (Bq/kg), whereas the range for <sup>40</sup>K was 119.43 ± 2.2 to 174.92 ± 2.6 (Bq/kg) with mean150.34 ± 2.4 (Bq/kg).

The method employs a finite sequence of positive integers separated by specific notational symbols, allowing for concise representation through an arrow-free notation: ( ​), where <em>b</em> represents the number of copies of <em>a</em>, and <em>n</em> denotes the arrow’s number described by a general formula. This recursive definition aims to replace the Knuth up-arrow notation and Conway chained arrow notation, which require the insertion of arrows between or within numbers. The new approach simplifies these expressions, eliminating the need for such symbols and providing a straightforward and concise method for representing large numbers. The aim was to develop a more efficient method, arrow-free notation, reducing the complexity and steps necessary with previous notations.</p> Dr Laith Al-ossm Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1224 Sat, 26 Apr 2025 00:00:00 +0200 Approximate Solutions of Nonlinear Integral Equations Using the Cubic B-Spline Scaling Method https://isnra.net/ojs/index.php/kjps/article/view/1218 <p>This paper examines a category of general nonlinear integral equations. These equations also include many special cases, such as functional equations and nonlinear integral equations of the Volterra type. In order to approximate the solutions to numerous physical, chemical, and biological issues, we implemented an approach that incorporates the fixed-point method and semi-vertical cubic scaling functions. We also obtain a numerical solution to the integral equation. Numerical examples illustrate the accuracy and validity of this method.</p> Mohammed Jabbar Adaay Al-Sharea Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1218 Mon, 28 Apr 2025 00:00:00 +0200 Assessment of IoMT-Based Remote Patient Monitoring Used to Support Healthcare System in Kirkuk City https://isnra.net/ojs/index.php/kjps/article/view/1242 <p>Recently, Internet of Medical Things (IoMT)-based telemedicine applications are acquiring increasing attention. This is due to their benefits, especially during pandemic circumstances. A popular example is the Remote Patient Monitoring (RPM) system, whose performance crucially depends on the components used, mainly the available Internet connectivity. Since similar RPM systems operating in different areas can perform differently, the reliability of these systems is questionable. Therefore, in this paper, the reliability of an RPM system is assessed and tested under realistic operation conditions in Kirkuk city. The purpose is to figure out to what extent the RPM system is applicable under the locally available technologies. Extensive tests by using a 12 Mbps optical Internet connection and two different cloud platforms show that the system encountered a maximum delay of about 59 seconds with an average availability exceeding 98%. The tests proved the robustness of the system, and it is henceforth recommended for practical application in Kirkuk city to support the healthcare system.</p> Lamees S.

This study used different types of data, including Landsat satellite imagery, soil texture, groundwater level, and slope. The Analytic Hierarchy Process (AHP) was utilized for multi-criteria decision analysis of possible landfill sites, linear regression was employed for population projection, and a Convolutional Neural Network (CNN) was utilized for Normalized Difference Vegetation Index (NDVI)/ Normalized Difference Built-up Index (NDBI) prediction. The suitability ratings for prospective dump sites were produced using the AHP-based Geographic Information Index (GIS) techniques. The results reveal that the selection of landfill locations minimizes environmental effects and advances environmentally sound waste management. The technique provides a framework for assessing the appropriateness of dump sites in various geographical areas. Moreover, the projections for the future emphasize Kirkuk City's need for upgraded waste management facilities. Furthermore, urban planners and politicians in Kirkuk City may benefit greatly from this research's data-driven approach to landfill site selection, which takes social and environmental concerns into account and has implications for sustainable waste management techniques.</p> Hana Kareem Shekho, Muntadher Aidi Shareef Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1219 Wed, 07 May 2025 00:00:00 +0200 Assessing The Environmental Quality of Kirkuk City and Taza District Based on Pressure-State-Response Framework for Winter 2023 Using Remote Sensing and GIS https://isnra.net/ojs/index.php/kjps/article/view/1225 <p>Evaluating a region's Ecological Environment Quality (EEQ) is an essential factor in deciding its urbanization and sustainable development rate. This study aims to find the Ecological Index (EI). It evaluates it using the widely used Pressure-State-Response (PSR) framework based on a set of statistical and remote sensing indices in Kirkuk City and Taza district. Sentinel-2 satellite images were used to obtain 12 indicators that offer a foundation for sustainable development decision-making for Kirkuk City and Taza District during the winter of 2023. The finding reveals that the ecological condition is healthy in winter due to the atmospheric conditions and the social and economic activities. It presents the main relation between environmental health and human activities.</p> Sundus Mohammed Azeez, Muntadher Aidi Shareef, Fawzi Mardan Omer Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1225 Sat, 06 Sep 2025 00:00:00 +0200 Synthesis, Characterization, and CO2 Capture Application of Cu(II)-paracetamol complex https://isnra.net/ojs/index.php/kjps/article/view/1335 <p>A cu(II)-paracetamol complex was synthesized and characterized using UV-Vis and FTIR spectroscopy and melting point analysis. The ligand paracetamol acted as a tridentate chelating agent, coordinating through the hydroxyl, carbonyl, and amine groups. The complex was found to be more soluble in DMSO. Job's method of continuous variation suggested a 1:2 metal-to-ligand stoichiometry. The synthesized Cu(II) complex was evaluated for CO<sub>2</sub> adsorption performance, demonstrating promising uptake capacity due to the strong affinity of the metal center for CO<sub>2</sub> molecules.</p> Mohanad Ali Sultan Copyright (c) 2025 Al-Kitab Journal for Pure Sciences https://creativecommons.org/licenses/by/4.0 https://isnra.net/ojs/index.php/kjps/article/view/1335 Mon, 08 Sep 2025 00:00:00 +0200 Effect of the Structural and Electrical Properties of Bi2-xPbxBa2Ca2Cu3O10+δ Superconductors with Partial Substitution of Lead by Bismuth https://isnra.net/ojs/index.php/kjps/article/view/1284 <p><strong> </strong>This manuscript discusses the preparation of Bi<sub>2-x</sub>Pb<sub>x</sub>Ba<sub>2</sub>Ca<sub>2</sub>Cu<sub>3</sub>O<sub>10+δ </sub>compounds by the method of solid-state reaction at the annealing temperature 850 C˚.

Elevated concentrations of heavy metals pose serious health risks to humans, including the potential for various cancers and damage to vital organs such as the liver, kidneys, and brain. In this study, seven tea samples were collected from the Iraqi market to examine their safety for consumption, indicated as T1-T7. The selection of the samples is based on a questionnaire answered by 140 individuals; T1-T6 samples are black tea, and T7 is green tea. Although the primary objective of this research is to determine the heavy metal content and toxicity of all the tea samples, the secondary one is to assess whether the drying process affects the levels of heavy metals by comparing green and black tea. The analysis is conducted on the samples via the Energy-Dispersive X-ray (EDX) and atomic absorption spectroscopy (AAS). The EDX results showed the presence of S, K, Al, and P in the T1 sample, while K, Al, and Mg were identified in the T2 sample, S, K, Al, and P in T3, only K in T4, K and Fe in T5, K, P, and S in T6, and Only K in T7. The results obtained from the AAS showed that all samples have normal concentrations of Fe and Zn but not for Ni (in samples T1, T2, and T3) and manganese (in samples T1, T2, T4, T5, T6, and T7). Those detected concentrations are higher than the permissible levels, and their levels are within the toxic limits according to the standard limits set by the World Health Organization (WHO) and the Food and Agriculture Organization (FAO). However, the other heavy metals (Cd, Cu, Pb, Cr, and Co) were either not detected or were below the detection limits of AAS, indicating that these samples are free from the mentioned toxic heavy metals.</p> Wedad H Al-Dahhan, Rafeef Dawood, Hassan N.
