Fast New Method for Estimation of Captopril in Pure and Pharmaceutical Preparation by Reaction with Ammonium Ce (IV) Sulfate in Acid Medium
type: item
description: Section: Chemistry Keywords: Captopril, Flow injection analysis, Hypertension, Ayah 6S×1-ST-2D solar cell Continuous flow injection analyzer. The determination of captopril (CAP) using a new continuous flow injection analysis (CFIA) method was given in this work CAP in its pure state and some of its pharmaceutical preparations. The technique can be described as simple, fast, sensitive, easy to operate, and low-cost. The CAP reacted with ammonium ceric(IV) sulfate (ACS)2(NH4 )2SO4Ce(SO4)2. 3 H2O in an acidic medium and the reaction led to the formation of a white, slightly yellowish precipitate. The formed precipitate was studied using Ayah 6S×1-ST-2D Solar cell-CFI Analyzer, a through the reflection of accident light on the surfaces of the precipitate particles at (0-1800), expressed as the response of the transducer measured in (mV). Some chemical and physical parameters were studied to provide the optimal conditions for the study. The calibration curve within the range of (0.07-3.0) mmol/L was linear, with a correlation coefficient (r) value equal to (0.9983), and the percentage value of linearity (R2%) was (99.65). The method's detection limit (L.O.D.) of the new method was 272.5 ng/25 µL; it was calculated by diluting the minimum concentration in the calibration curve gradually. RSD% was less than 0.2% for 0.9, 1.5, and 3.0 mmol/L concentrations of C.A.P. for n=8. The method was successfully applied to estimate C.A.P. in three pharmaceutical preparations, each produced by a different company. The new method was compared with the UV-Spectrophotometric method (classical method) at λmax= 207.2 nm by using the method of standard additions. Both the t-test and the F-test were conducted to ensure that there wasn't a significant difference between the new method and the conventional one. The results of both tests showed, at a confidence level of 95%, that there was no significant difference.

Effect of Graphene Oxide Concentration on the Antibacterial Activity of GO–ZnO Hybrid Nanocomposites
type: item
description: Section: Chemistry Keywords: Bacterial effectiveness, Graphene oxide, Nanocomposite, Spin-coating technique, Zinc oxide Graphene oxide (GO) with zinc oxide nanoparticles (ZnO NPs) was synthesized using sol-gel and spin-coating procedures. This study aims to assess the antibacterial properties of ZnO-GO nanocomposites produced by spin coating with varying GO concentrations. So, different concentrations of GO NPs (10%, 30%, and 50%) were added to ZnO to assess the antibacterial activity. Structural and morphological properties of ZnO-GO were characterized using X-ray diffraction, field-emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy, and atomic force microscopy. The crystalline size of the pure ZnO NPs decreases with the increase of GO concentration, and the average crystalline size is 32.875 nm. The FESEM images showed that all samples contained mostly spherical-shaped particles with a high tendency to agglomerate. Also, the antimicrobial activity of the synthesized NPs (ZnO-GO) was investigated against the Gram-positive bacterium Staphylococcus aureus, the Gram-negative bacterium Escherichia coli, and the fungus Candida albicans. The antibacterial properties of three compounds were highly efficient. Additionally, it was demonstrated that ZnO-GO has higher antibacterial activity than pure ZnO NPs.

Nanoscale Processing of Euphrates Poplar for Methylene Blue Removal
type: item
description: Section: Chemistry Keywords: Adsorption, Euphrates poplar, Kinetics, Methylene blue, Thermodynamics, Wastewater treatment The potential of Euphrates poplar (EP) leaves, a plentiful agricultural waste, as a sustainable adsorbent for wastewater treatment is examined in this work. FTIR, FESEM, and XRD were used to characterize activated carbon (AC) derived from EP leaves by carbonizing them at 400°C for 3 hours. Brunauer found a surface area of 3.77 m²/g using the Brunauer–Emmett–Teller (BET) technique. Methylene blue (MB) adsorption trials showed that with an ideal contact time of 60 minutes, the removal efficiency exceeded 91%. Temperature and pH significantly affected the adsorption process, and the addition of EP nanoparticles enhanced dye uptake. According to kinetic modeling, the Temkin isotherm (R²= 0.904) provided the most accurate equilibrium fit, while the pseudo-second-order model (R²= 0.999) best explained the adsorption behavior. Positive ΔS° values indicated greater unpredictability at the solid-solution interface, and thermodynamic parameters confirmed that the adsorption was endothermic and spontaneous. These results demonstrate that Euphrates poplar leaves are an economical and environmentally beneficial adsorbent for dye removal, providing a viable alternative for wastewater treatment applications.

Flow Injection Spectrophotometric Indirect Assay of Amlodipine Besylate Using Crystal Violet Agent
type: item
description: Section: Chemistry Keywords: Amlodipine Besylate, Crystal violet, Flow injection, Merging zone Amlodipine Besylate (AMB) was determined in pharmaceutical and biological samples using a continuous-flow injection technique characterized by simplicity, rapidity, cost-effectiveness, sensitivity, and a broad linear range. This study aims to develop and evaluate a flow injection analysis method for the rapid and reliable determination of Amlodipine in chemical and biological samples using minute quantities. The suggested method is based on the oxidation of the drug with a potassium bromide-potassium bromate mixture, followed by reaction with crystal violet as a reagent to produce a blue product, the absorbance of which was measured at 592 nm. The coefficient of determination (R2) is 0.9978, and the calibration curve's linear range is 10-250 μg/mL. The limit of detection for the standard was 2.46 μg/mL, the recovery was 99.81%, and the relative standard deviation was 2.4%. The proposed method was successfully used to estimate AMB in biological and pharmaceutical samples. Compared with those obtained using a United States Pharmacopeia reference method, the results were favorable, and at the 95% confidence level, there was no discernible difference in accuracy and precision

description: Section: Chemistry Keywords: 4-Aminoacetophenone, Azo dye, 2,3-Dichlorophenol, Metal complexes A fabricated Azo ligand (E)-1-[4-(3,4-dichloro-2-hydroxyphenyl) diazenyl] phenylethan-1-one was produced by a coupling reaction between diazonium salt made from p-aminoacetophenone and a basic solution of 2,3-dichlorophenol. The azo compound was used to form complexes with Cr(III), Co(II), Ni(II), and Cu(II) ions at a 2L:1M molar ratio in an alcoholic medium. The ligand and its complexes were characterized using a set of spectroscopic techniques to obtain chemical and structural information. Infrared with Fourier transformation; ultraviolet and visible; ¹H/¹³C nuclear magnetic resonance; mass; thermal analysis and micro elemental analysis spectrometry, as well as molar conductivity. The results certified the chemical moiety and geometric fabrication. Azo dye acts as a bidentate ligand with phenol/hydroxy terminals. The finding was that Cr(III), Co(II), and Ni(II) complexes were characterized by a six-coordinate (distorted octahedral) geometry, whereas the Cu(II) complex had a tetrahedral structure. Thermal decomposition of the ligand and the selected complex was studied to assess stability upon heating and to determine the final residue.

Extension Odd Generalized Rayleigh Inverse Rayleigh Distribution: Structure and Properties
type: item
description: Section: Mathematics Keywords: T-X family, point estimation, Inverse Rayleigh, quantile function The Extension Odd Generalized Rayleigh Inverse Rayleigh (EOGRIR) distribution is a novel statistical model that leverages existing distribution families in a flexible manner. This model enhances the ability of standard distributions to analyze data. It makes it easier and faster to examine and model different types of lifetime and reliability data. The essay thoroughly examines the fundamental mathematical characteristics of the EOGRIR distribution. Some examples include series expansions, moments, the quantile, skewness, Rényi entropy, kurtosis, order statistics, and the moment generating function. These traits help us understand how the proposed distribution works and how its mathematical principles operate. We also examine methods for estimating parameters, with a focus on maximum likelihood estimates (MLE), to ensure that inference and parameter estimates are accurate. The EOGRIR distribution is likely to have a significant impact on statistics, as it offers a more flexible and comprehensive framework that may be superior to the existing ones

Determination of crystallite size and strain values by fourier method for α- Al2O3
type: item
description: Section: Physics Keywords: crystallite size The sintering of Al(OH)3 powder for 2 hours each run in the temperature range 1673 K to 1873 K gives rise to the following crvstallization sequence: γ- Al2O3 → γ-θ -Al2O3 → θ+α- Al2O3 → α- Al2O3 The crvstallographic structures of the above products are assessed by x-ray diffraction method . The variation of crystallite size and root mean square (rms) strains in a- Al03 powder with sintering the temperature range 1673 K to 1873 K are studied by applying Fourier method using Mitra &Misra technique for 3 crystallographic reflections (104), (113) and (116). The results show that the lower temperature α- Al2O3 (1673 K) derived from Al(OH)3 produces lower crystallite size and higher rms strain . On the other hand, rms strain decreases with increasing the temperature to 1873K and the differences between the broadening of above reflections are decreased. Thus, the anisotropy higher temperature of sintering (1873K).Lower temperature sintering is reduced at1673 K of AI(OH)3 yield α- Al2O3 compacts of higher value of micro hardness number 884 and this value drops to 731 at 1873 K.

Artificial Intelligence Model of Iraqi Paper Currency Detection in Vending Machines
type: item
description: Section: Computer Keywords: Artificial intelligence (AI); Convolutional Neural Network (CNN); Vending machines (VM); Mahalanobis-distance (Mah-dis) The development of technology is becoming necessary in multiple fields that specialize in human interaction life. This has contributed to increasing awareness of electronic financial transactions by enhancing the ease of handling currencies, especially by employing vending machines in commercial markets and airports. Vending machines have become widespread nowadays, and due to their ease of use for customers, it has become necessary to pay attention to this type of device. Due to the different currencies adopted in countries around the world, there has emerged a need to increase the flexibility of programming these machines to be suitable for the countries using the devices. In this research, an intelligent convolutional neural network model CNN was built based on artificial intelligence techniques integrated with the Mahalanob distance method to embed the suggested “CNN-ThrMah” model. The dataset, which contains types of banknotes issued by the Central Bank of Iraq, was collected using digital scanning supplied by a high-resolution camera to achieve high accuracy. Then, the “CNN-ThrMah” model was built and trained on this data, using the optimizer “AdamW” to achieve a high level of accuracy in detecting the types of currencies for the tested data that the model had not seen. While a Mahalanobis-distance method is used to prevent the model from overfitting when generalizing in the real world. This model achieves high accuracy for all detections of all positive samples of Iraqi currencies and negative samples of non-currency items that contain currency from other countries

Side-Channel Attack-Resistant Smart Card Encryption Using Neural Signal Obfuscation
type: item
description: Section: Computer Keywords: Neural Signal Obfuscation (NSO), Side-Channel Attacks, AES-128 Encryption, Machine Learning, Power Analysis Crypto systems deployed in smart cards and embedded devices are vulnerable to side-channel attacks, in which adversaries exploit power consumption to recover secret keys. Correlation power analysis (CPA) and machine-learning-based attacks can break AES-128 implementations with relatively few traces. This work investigates Neural Signal Obfuscation (NSO) as a practical countermeasure for an AES-128 smart card-style implementation. We first acquire and characterize power traces from the target device and quantify baseline leakage using traces-to-disclosure (TTD), guessing entropy (GE), signal-to-noise ratio (SNR), and the success rate of a neural network attacker. We then design and train a lightweight one-dimensional convolutional obfuscator that transforms power traces to suppress exploitable leakage while preserving correct cryptographic functionality. Re-evaluating obfuscated traces under the same CPA and machine-learning attacks shows that NSO increases TTD, reduces GE and SNR, and lowers the attacker's accuracy, forcing an adversary to collect significantly more traces to recover the key than in the unsecured baseline implementation.
