Performance of the water cycle algorithm in optimal economic design of passive power filter

Abstract Harmonic distortion in power systems, caused mostly by nonlinear loads, results in significant power quality (PQ) issues such as higher losses, lower power factor (PF), and equipment malfunctions. Passive power filters (PPFs), which use tuned combinations of inductors an...

Attenuation of cyclophosphamide toxicity by protective effects of curcumin in albino rats model

Abstract Background Chemotherapy primarily treats cancer by using drugs to kill cancer cells. Curcumin, a natural adjuvant, shows promise in preventing side effects. Purpose This study seeks to determine curcumin’s protective effect against cyclophosphamide toxicity. Materials an...

Green-synthesized nanoparticles for glass ionomer cement reinforcement: a systematic review of their antimicrobial, mechanical, and physicochemical properties

Abstract Aims This systematic review critically evaluates the antimicrobial performance, mechanical properties, and fluoride release of glass ionomer cements (GICs) modified exclusively with green-synthesized nanoparticles. The review highlights how eco-friendly nanoparticle prod...

Cardiac changes in children with post-streptococcal glomerulonephritis: a prospective observational study

Abstract Background Acute poststreptococcal glomerulonephritis (PSGN) is the most common type of glomerulonephritis which may involve multiple organs, including the heart. This study aimed to explore cardiac status of children with PSGN and track progression of any cardiac impair...

Immunohistochemical evaluation of androgen receptor expression in endometrial carcinoma and its clinicopathological significance

BACKGROUND: Endometrial carcinoma (EC) is a leading gynecological malignancy predominantly driven by hormonal imbalances. While the roles of estrogen and progesterone are well established, the influence of androgenic signaling, specifically through the androgen receptor, remains...

Characterization of PMMA/PEO thermoplastic modified with nanosized Cr 2 O 3 /Fe 2 O 3 : Nanocomposites for optoelectronics and dielectric devices

This study is dedicated to the synthesis of nanocomposites based on Cr 2 O 3 - and Fe 2 O 3 -reinforced PMMA/PEO with optimized performance for optoelectronics and energy storage applications. The fillers and films were prepared by inexpensive chemical methods. The effects of add...

Integrated geophysical and hydrogeochemical characterization of a fractured limestone aquifer in new Tuna El Gabel village, West El-Minia, Egypt

Abstract Groundwater is a vital component of water supply in arid regions, such as West El-Minia Governorate, Egypt, where water scarcity is projected to worsen, with per capita water supply expected to drop below 500 m 3 by 2025. In response, Egypt’s One and a Half Million Fedda...

Enhancing PMSM Drive Performance Under Open-Phase Fault Using Fractional-Order Controllers

Open-phase faults (OPFs) represent a major challenge in PMSM drive systems due to the induced current imbalance, torque ripple, and degradation in speed regulation performance. Although fractional-order controllers and model predictive control have been extensively investigated f...

Hybrid ZnO–CuO nanoparticle-enhanced waste cooking oil biodiesel for improved diesel engine performance and emission reduction

Abstract The well-known trade-off between engine emissions and performance is one of the primary obstacles to using waste cooking oil (WCO) biodiesel. WCO biodiesel frequently results in incomplete combustion and decreased efficiency because to its relatively high viscosity, poor...

Molecular modeling characterization of cellulose and chitosan metal oxide hybrid interfaces

Abstract The interfacial electronic structure of biopolymer–metal oxide hybrids determine their stability, yet this structure is still not well understood. Here, we report a density functional theory study of 10 model systems consisting of cellulose and chitosan functionalized wi...

Dual GLP-1/glucagon receptor agonists in metabolic dysfunction–associated steatotic liver disease: a meta-analysis of randomized controlled trials

Metabolic dysfunction–associated steatotic liver disease (MASLD) affects approximately one-third of the global population. We aimed to evaluate the efficacy and safety of dual glucagon-like peptide-1 and glucagon receptor agonists (GLP-1/Gcg RAs) in patients with MASLD. PubMed, W...
