Let be a commutative ring with identity and be a unitary left -module. The main goal of this work is to introduce and study the idea of a P-essential maximal submodule, which is a generalization for maximal submodules, as a proper submodule of an -Mod is called P-essential maximal (shortly Pe-max) if for any P-essential submodule of a module with implies that , where a sub mod of an -Mod is called P-essential in , if such that , implies . An ideal of a ring is called P-essential maximal ideal, if for any Pe-ideal of such that implies . And we introduce the concept P-essential local, an -Mod is called P-essential local module (for short Pe-local), if it has only one Pe-maximal submodule, which is contains

Show MoreGold nanoparticles (AuNPs) act as protective agents for liver health by inhibiting oxidative stress factors, and laser treatment combined with green synthesis enhances their protective properties. In this study, AuNPs were prepared by green synthesis using an aqueous mint leaf extract (5 ml of aqueous mint extract was added to 10 ml of a gold salt solution). After that, the produced AuNPs were exposed to laser pulses from a 532 nm crystal with energy from 500 to 1300 mJ to determine the toxicity of AuNPs exposed and unexposed to laser pulses on hematological and biochemical parameters and liver tissues. 40 Adult male albino rats were divided into four groups: group 1 was control, group 2 was intraperitoneally injected with an aqueous ext

The current study endeavored to isolate and identify Escherichia coli from the wastewater of multiple hospitals in Baghdad City, Iraq, and characterize its antibiotic resistance patterns. The study resulted in identifying, by biochemical means using the VITEK system, a total of 50 E.coli isolates. Antibiotic susceptibility tests for 11 antibiotics were conducted on each isolate via the Kirby–Bauer (KB) disk diffusion method. Overall, all isolates showed considerable resistance to the following antibiotics: erythromycin and clarithromycin (100%), amoxicillin (86%), cefo

Show MoreThis paper aims to introduce a novel univariate probability distribution called the Weibull X-Lindley distribution (W-XLD), designed to be more flexible in modeling data with different patterns. The core idea behind this distribution arose to address some of the limitations of traditional distributions by introducing a form factor to increase flexibility to the proposed distributions. The technique used to construct W-XLD relies on multiplying the survival functions of the X-Lindley and Weibull distributions to find the W-XLD survival function. Based on this, the statistical functions of W-XLD were defined, including the cumulative distribution function (cdf), the probability density function (pdf), and the risk function. The shapes of t

A factorial experiment was conducted to evaluate the efficacy of melatonin and boron in mitigating the adverse effects caused by salinity stress on tomato (Solanum lycopersicum L.) physiology and fruit quality. The experiment consisted of applying three levels of melatonin (0, 200, and 400 mg L-1) and three levels of boron (0, 5, and 10 mg L-1) to tomato plants. The results demonstrated that melatonin and boron mitigated several damaging effects of salt stress, including a reduction in chlorophyll content, antioxidant activity, lycopene concentration, and reduced sugar levels.

Show MoreThis study aimed to evaluate the water quality of the Tigris River in Baghdad using benthic invertebrate communities as biological indicators A total of 5722 individuals representing 12 taxa were collected including Chironomidae Gammaridae, Thiaridae, Physidae, Lemaneaceae, Nematoda, Tubificidae, Rotifera, Planariidae, and Naididae. Chironomidae was the less abundant group accounting for 27% of the total community followed by Gammarus spp. (25%), while Potamothrix spp. showed the lowest abundance (0.16%). Species richness index (D) values were relatively similar among the studied sites recording 3.25 at S1, 3.30 at S2, 3.16 at S3, and 3.24 at S4 Shannon–Wiener diversity index values ranged from 1.3 to 1.78 wi

Show MoreIn the present study, we propose a new model, identified as the Shanker Rayleigh distribution, which is derived by combining the survival functions of the classical Rayleigh and Shanker distributions, both of which have a scale parameter only. We developed this hybrid model to offer the additional modeling flexibility required for complex lifespans that single-unit distributions cannot accurately represent. Theoretical characteristics of the distribution (probability density function, cumulative distribution function, survival, and hazard rate function) are derived in closed form. In addition, important distributional properties, namely the raw and central moments, moment-generating function, and quantile function, are methodically exami

Show MoreThis study investigates the structural, thermal, and electrical properties of polyvinyl alcohol (PVA) nanofibers doped with a ZnO–CoO binary oxide, synthesized via a controlled electrospinning process at an applied voltage of 16 kV and a flow rate of 0.8 mL/h. FESEM analysis revealed a systematic morphological transition from smooth, uniform fibers to a bead-on-string structure as the dopant concentration increased from 1 wt% to 5 wt%. Moreover, quantitative analysis revealed fine fiber morphologies, with the minimum diameters reaching 17 nm, 23 nm, and 26 nm of different concentration ratios, respectively. X-ray diffraction (XRD) analysis confirmed the amorphous nature of both the pristine and doped nanofibers. The absence of metallic

From 180 clinical specimens, 50 isolates were obtained from ear swabs, burn wounds, sputum, urine, and wound samples. This study investigated quorum sensing genes (pqsA, pqsB, pqsC, pqsD) and their association with multidrug resistance (MDR). Nineteen isolates (38%) were multi-drug resistant (MDR) and 31 (62%) were non‑MDR. PCR analysis demonstrated detection rates of 89.5% for pqsA, 94.7% for pqsB, 94.7% for pqsC, and 73.7% for pqsD. Antibiotic susceptibility testing revealed the highest resistance to colistin (84%) and imipenem (76%), with moderate resistance to ciprofloxacin (32%) an

This project focuses on the analysis of changes in spatio-temporal agricultural land in the period 2015 to 2025 and determines how the transformation of agricultural land affects land surface temperature (LST) in western Karbala, Iraq. From 2015 to 2025, agricultural lands will increase considerably with the total vegetation area rising from 32.65 km² in 2015 to 152.75 km² in 2025. Additionally, areas with excellent ecological conditions improved from 18.25 km² to 24.57 km², indicating enhanced environmental stability due to agricultural expansion. The LST trends from 2019

Show MoreAllium cepa extract was used to prepare AgO NPs, NiO NPs, NiO-AgO NCs by plant-mediated synthesis, all characteristics of these nanoparticles and antibacterial properties have been studied. XRD analysis confirmed the crystalline nature of the synthesized nanoparticles. The average crystalline size was 14.75nm, 38nm and 36.4 nm for AgO NPs, NiO NPs and NiO-AgO NCs respectively. NiO NPs were hexagonal, while AgO NPs were monoclinic phase. The NiO-AgO NCs represents a hybrid structure composed of NiO NPs and AgO NPs phase. EDX analysis verified that all samples contained the elements that were present (O, Ni, and Ag).

... Show MoreThis study examines how nuclear symmetry energy and its slope change in pairs of mirror nuclei: ⁴⁰K–⁴⁰Sc, ⁴¹K–⁴¹Ti, ⁴²K–⁴²V, ⁴³K–⁴³Cr, and ⁴⁴K–⁴⁴Mn, using three different Skyrme parameterizations like Msk7, Sk0, and Bsk9. This study looks at how different nuclear properties, like the difference in charge radius, the imbalance between neutrons and protons, and the thickness of the neutron skin, are affected by different symmetry energy constants. The results show that when the symmetry energy goes up, both the thickness of the neutron skin and the difference in charge radius and mirror radius also go up, while the slope parameter changes a lot with nuclear asymmetry.
