<b>Efficiency of Nano powders of Cloves, Cinnamon, and Turmeric in Ochratoxin A (OTA) production by <i>Penicillium polonicum</i></b>
...Show More Authors

The study aimed to evaluate the efficiency of Nano powders of Cloves, Cinnamon, and Turmeric in inhibiting fungal growth and Ochratoxin a (OTA) production by Penicillium polonicum and reducing the toxin in liquid media. The research highlights the reduction of ochratoxin toxins using environmentally friendly plant Nano powders that are safe for human and animal consumption. They are mainly used in food as flavorings and preservatives. The Nano treatments of cloves, cinnamon, and the mixture (Cloves-Cinnamon-Turmeric) achieved complete inhibition of fungal growth and OTA toxin production by 100% for concentrations (2, 4, 6, 8%). The treatment of Nano Turmeric powder did not inhibit fungal growth at all concentrations. However, it

Drought stress resulting from the depletion of available water in the soil leads to disturbances in the plant's metabolic processes, reducing productivity due to its decreased ability to absorb water and essential nutrients. This study aimed to evaluate the interactive effects of three bread wheat varieties (Adna 99, Bohooth 22, and Wafia), three drought stress levels (25% control, 50%, and 75% depletion of available water), and foliar application of micronutrients(control) iron (Fe), zinc (Zn), copper (Cu), and manganese (mn) at 100 mg L-¹) and no spraying on agro-biochemical characteristics.

A low-cost thermal evaporation deposition technique has been used for the preparation of Cu2Se thin films on glass substrates at RT with a thickness of 500 nm. Structural and optical properties of these films were investigated.  Structural characterization of the films was done using X-ray diffraction XRD analyses, atomic force microscopy AFM was used for the morphological characterization of the film samples, and UV-Vis spectroscopy was also used for the characterization of the samples. The films have been treated at different temperatures (403, 453 &503) K for 1 hour. X-ray diffraction (XRD-with wavelength 1.54 A) study of these films suggests a cubic structure and has prominent (220) orientation. And AFM analysis, it i

<b>Autoregressive Models Estimation Selection with Known Marginal Distribution</b>
...Show More Authors

A time series is a sequence of observations recorded at regular intervals. Time series analysis has applications in diverse fields such as finance, stock prices, economics, environmental science, and social network data analysis. The recorded series is used to represent a measurable quantity or attribute, such as temperature readings, economic indicators, or other variables, depending on the context of the analysis. The idea of time series analysis is to identify patterns, trends, or underlying structures within the data, as well as to make predictions or forecasts about future values based on previous observations. Autoregressive (AR) models are widely used in modeling and forecasting data from time series. This work focuses on AR model

The ground-state properties like the nuclear densities and the root mean square (rms) radii for exotic neutron-rich nuclei 14B and 18N have been investigated using the Skyrme Hartree-Fock and Bear-Hodgson calculations to study the structure of these nuclei. The results of the evaluation are contrasted with the experimental data that is currently available. It found that a common feature of the neutron and matter densities for the above-selected exotic nuclei is the long tail behavior. We assumed that both 14B and 18N have a structure of the core nuclei 13B and 17N plus a valence neutron. It found that the structure of the valence one-neutron of 14B and 18

<b>Study of the Properties of Image Formation by an Optical System Consisting of a Diffractive Lens</b>

Diffractive lenses form images based on the principle of light diffraction, unlike conventional lenses that rely on the phenomenon of refraction to form images. Diffractive lenses consist of precisely aligned structures of holes or slits that act as optical gratings. They are arranged to give the lens the optical property of changing the path of incident rays, creating an image pattern similar to that of conventional lenses. This work aims to study the image characteristics formed by diffractive lenses by conducting a computer simulation in the Zemax optical design software. The analysis tools available in the software are then used to study the quality of the resulting image and evaluate the performance of the diffractive lens. The resu

<b>Enhanced Multi-Objective Evolutionary Algorithm for Community Detection Using a Community Strength-Based Mutation Strategy</b>

Community structures are fundamental in understanding the structure and functionality of complex networks. Different optimization algorithms, including both single-objective and multi-objective approaches, have been employed to address the challenge of community detection. Recently, multi-objective evolutionary algorithms (MOEAs) have attracted many researchers to identify communities in static networks. Many algorithms have been proposed to find a solution that achieves a trade-off between exploring new areas of the solution space and improving the quality of existing solutions. In this trade-off is crucial; whereas exploitation improves existing solutions, it may fail to find better solutions from insufficiently explored regions of the

<b>Enhanced OCR Techniques for Recognizing Mathematical Expressions in Scanned Documents</b>

     When OCR systems are utilized to recognize mathematical expressions in scanned documents, they encounter numerous challenges. These challenges arise because the mathematical expressions use an extensive array of symbols, variables, numbers, and operations, each with its distinct writing style. Moreover, mathematical expressions have a hierarchical relationship and adhere to logical rules governing the grouping of their components. This paper presents a three-step approach segmentation, symbol recognition, and interpretation to overcome these issues. The segmentation process aims to identify and separate each symbol based on its spatial location. Then, various features are extracted to describe the horizontal and vertical project

Azo dyes are the most common and widely used dyes, accounting for more than half of each year's dyes. In this work, a complete description of a new innovative series of compounds with the elements [Ag (I), Zn (II)] generated from the guanine azo dye ligand (GAB) 8-[1-(3-carboxy) azo] guanine has been studied. The structural formula was studied using several physicochemical analyses and spectroscopic techniques (FT-IR spectra, UV-Vis). The FTIR spectrum of the ligand (GAB) was compared to the spectra of the metal ion complexes formed to determine its identity.

The suggested mathematical model for studying the effect of refuge on the dissolved oxygen in the plankton ecosystem is based on measurements of dissolved oxygen, phytoplankton, and zooplankton populations. The aim of this work is to find out the potential equilibrium and to investigate their behaviour. The study shows that there are three points of equilibrium. The feasibility requirements and stability conditions for all steady states are determined. Using the consumption of oxygen by zooplankton as a bifurcation parameter, we test for the presence of Hopf- bifurcation for the interior equilibrium. It is shown what conditions must be met for stable limit cycles. Finally, a numerical simulation is conducted to back up the analytical fin
