Understanding and Using Animal Models of Hepatotoxicity.

Hepatotoxicity is a critical health hazard, primarily contributing to the increased incidence of deaths globally. The liver is one of the major and extremely vital organs of the human body. Autoimmune diseases, viruses, exposure to toxicants such as carcinogens, and changes in eating habits can all cause liver problems, among other things.

Unraveling the Electrochemical Insights of Cobalt Oxide/Conducting Polymer Hybrid Materials for Supercapacitor, Battery, and Supercapattery Applications.

This review article focuses on the potential of cobalt oxide composites with conducting polymers, particularly polypyrrole (PPy) and polyaniline (PANI), as advanced electrode materials for supercapacitors, batteries, and supercapatteries. Cobalt oxide, known for its high theoretical capacitance, is limited by poor conductivity and structural degradation during cycling. However, the integration of PPy and PANI has been proven to enhance the electrochemical performance through improved conductivity, increased pseudocapacitive effects, and enhanced structural integrity.

NiVO Marigold Structures with rGO Coating for Enhanced Supercapacitor Performance.

In this work, NiVO (NVO) and NiVO-reduced graphene oxide (NVO-rGO) are synthesized hydrothermally, and their extensive structural, morphological, and electrochemical characterizations follow subsequently. The synthetic materials' crystalline structure was confirmed by X-ray diffraction (XRD), and its unique marigold-like morphology was observed by field emission scanning electron microscopy (FESEM). The chemical states of the elements were investigated via X-ray photoelectron spectroscopy (XPS).

Numerical analysis of stresses on angular contact ball bearing under the static loading with respect to race thickness and housing stiffness.

A 3-dimensional model of the angular contact ball bearing (ACBB) was modeled using Abaqus/standard (Dassault systems- version 2017) to investigate the influence of race thickness on the bearing performance. It was found that the ability to support higher contact stress increased with race thickness. However, large deformations were found to occur on outer race with thickness of 3.

Elastomeric seal stress analysis using photoelastic experimental hybrid method.

Stress freezing is an important and powerful procedure in 3-dimensional experimental stress analysis using photoelasticity. The application of the stress freezing technique to extract stress components from loaded engineering structures has, however, declined over the years even though its principles are well established. This is attributed to huge costs arising from energy consumption during the process.

Misplacement or migration? Extremely rare case of cardiac migration of a ureteral j stent.

A 29-year-old woman with mild back pain when coughing and suprapubic discomfort after voiding was admitted to Pusan National University Hospital. Two weeks earlier, she had undergone a hysterectomy and right-sided ureteroneocystostomy for uterine atony and right ureteral injury with bladder rupture. Computed tomography showed that a ureteral J stent extended from the right ovarian vein to the right cardiac chamber.

A novel tape spring hinge mechanism for quasi-static deployment of a satellite deployable using shape memory alloy.

A tape spring hinge (TSH) is a typical flexible deployment device for a satellite and becomes frequently used due to its simplicity, lightweight, low cost, and high deployment reliability. However, the performance of a TSH is quite limited due to trade-offs among deployed stiffness, deployment torque, and latch-up shock despite its many advantages. In this study, a novel conceptual design that circumvents the trade-offs among functional requirements (FRs) is proposed.
