IDAL distribution is based on expanding the exponential Weibull distribution by adding a IDAL distribution is based on expanding the exponential Weibull distribution by adding a third parameter, which is a shape parameter, to the exponential-Weibull distribution. This modification was done in order to create models that are more flexible and realistic. The IDAL distribution is characterized by three parameters, which are the scale parameter and two shape parameters. Estimating the reliability for a Noval distribution. The unknown parameters of its distribution have been estimated which have the first of these methods is the Maximum Likelihood Estimate (MLE) method, followed by the Maximum Entropy Estimation (MEE) method. A comparison of

Survival analysis is a fundamental statistical tool for studying the period leading up to a specific event, such as patient death or device failure. Interest in this analysis has grown due to its ability to provide accurate insights into survival rates and survival function estimation in various fields. This paper modifies the Log-logistic Distribution ( ) by adding a shape parameter to enhance its ability to predict more effectively.  After that, a new hybrid meta-heuristic algorithm (PSWGO), combining particle swarm optimization with the gray wolf algorithm, is proposed to estimate the survival function. To compare and investigate the performance of the proposed algorithm with three meta-heuristic algorithms (particle swarm optimizati

This paper shows new approximate ways to solve nonlinear ordinary differential equations using two methods that repeat steps: the Adomian decomposition method (ADM) and the optimal Adomian decomposition method (OADM). These equations are extensively utilized in fluid dynamics and engineering. The OADM sets itself apart by incorporating an optimal control parameter that enhances solution accuracy and accelerates convergence, providing a distinct advantage over the ADM. The two methods have been applied to three important equations: the Darcy-Brinkmann-Forchheimer moment equation, the Blasius equation, and the Falkner-Skan equation. The effectiveness of the two methods was assessed by looking at how quickly they converged and the largest e

The superconducting compound ( Pb_1-xCd_xBa₂Ca₂Cu₃O_{9+ δ} ) was prepared using the solid- state reaction (SSR) method as it is the most common method in the preparation of superconducting compounds, where the study was carried out at addition weights (x=0,0.15) to observe the effect of replacing lead with cadmium and the effect of this replacement on both the characteristics and behavior of the samples in terms of electrical resistance and critical temperature, where all samples displayed superconducting behavior.

Constructing two-dimensional (2D) composites using layered materials is considered a practical approach to achieving high-efficiency photocatalysts. This study aims to prepare manganese oxide nanoparticles (NPs) from the aqueous extract of thyme leaves, characterize them by spectroscopic methods, and bridge the gap by developing an environmentally friendly, photostable coating and evaluating its efficiency in degrading the methylene blue (MB) dye under sunlight, suitable for practical water treatment applications. In this work, a 2D nano-photocatalytic coating of Mn₃O₄:Ag was developed for the efficient removal of organics and pollutants from water under sunlight. The method involves synthesizing a photocatalytic na

Staphylococcus aureus is one of the causes of serious diseases that cause a wide range of infections, including urinary, skin, and respiratory infections. Thus, it has shown strains resistant to antibiotics, so that studying the molecular basis of virulence in staphylococcal bacteria becomes more important. The aim of this study is to investigate the presence of teicoplanin-associated genes (A, B, R) in        S. aureus bacteria taken from clinical samples by PCR technique. 25 clinical samples from patients with respiratory diseases, skin ulcers, and urinary tract infections were collected from Yarmouk Teaching Hospital for a period ranging from October 2024 to January 2025. The presence of       

Thin films of ZnO1-xAgOx nanostructures were successfully deposited on glass substrates using pulsed laser deposition with varying AgO nanoparticle concentrations. Structural and optical characterizations were performed to evaluate the effect of AgO incorporation. XRD patterns confirmed a hexagonal polycrystalline structure, with additional peaks for cubic silver or silver oxide due to AgO inclusion. Crystal size slightly increased at x = 0.05 and 0.25, indicating enhanced growth, while it decreased at other ratios due to lattice strain and defects. FTIR analysis showed Zn–O stretching modes, hydroxyl, carbon-based groups, and Ag–O bands, confirming successful incorporation. AFM results revealed reduced surface roughness with low AgO

Urinary tract infections are mainly caused by uropathogenic Escherichia coli, which represent a significant global issue along with the rising of antibiotic resistance and treatment challenges. The aim of this study was to evaluate ciprofloxacin efficacy as a treatment in animal models following infection with multidrug-resistant UPEC and multidrug-susceptible UPEC and to determine the nephrotoxic effect of these antibiotics on the renal cortex. Up to 76 E. coli isolates were collected from UTI patients in Baghdad province, characterized by morphological and biochemical features, and confirmed using the Vitek-2 compact system. Mice were orally infected via gastric gavage with G33 using a bacterial load of 107 cells/ml,

      The prevalence of diabetes is increasing rapidly and is now recognized as a significant global health problem. Diabetes occurs when a person does not produce enough insulin due to an imbalance in insulin production. This can lead to the failure of organs and tissues such as the kidneys, heart, blood vessels, eyes, nerves, and kidneys. As a result, early diagnosis and classification of type 2 diabetes mellitus (T2DM) are critical to aiding physician assessments. Subsequently, the current study aims to determine irisin levels in patients with T2DM and pre-DM as early predictors for disease cases. The current study included 138 subjects divided into three groups based on fasting blood glucose (FBG) and glycosylated hemoglobin cri

Osteoporosis (OP) is a bone disease that makes bones more brittle and increases the risk of fractures. Osteoporosis, the most common type in postmenopausal women, is characterized by decreased bone mineral density, skeletal microstructure disintegration, and increased bone fragility. Osteoporotic fractures are more common in women than breast cancer, myocardial infarction, or stroke, and they also incur higher hospital treatment costs.

The complexation between folic acid and a typical polyaromatic hydrocarbon, fluorene, was investigated using FTIR and UV spectra. Appearance of a new IR band at 2401cm−1 demonstrates that NH2–C=N moiety on pterin ring in folic acid is protonated when fluorene is introduced. The emergence of two charge transfer bands at 217 nm and 278 nm in UV difference spectra shows the presence of π-π complexation between folic acid and fluorene. These experiments confirm that fluorene could combine with the pterin ring of folic acid through π-π donor–acceptor interaction and induce the protonation process in folic acid upon strengthening electron accepting ability of pterin ring. The results suggest that complexatio
