This study involves a novel CuO/CoFe₂O₄/MWCNTs (CCT) nanocomposite, developed by integrating cobalt ferrite (CoFe₂O₄) and copper oxide (CuO) nanoparticles onto multi-walled carbon nanotubes (MWCNTs), for the degradation of tetracycline (TC) under visible light. The photocatalyst was extensively characterized using XRD, HR-SEM, EDX, HR-TEM, UV-Vis, BET, and PL analysis. The synthesized CoFe₂O₄ and CuO nanoparticles exhibited crystallite sizes of 46.

- Spondylo-thoracic dysplasia (STD) is a rare congenital condition that affects the vertebrae and thoracic area, often leading to serious respiratory issues and a high risk of early death in neonates.
- The text details the case of a one-day-old male newborn with severe respiratory distress and various physical anomalies, including scoliosis and rib deformities, identified through clinical examinations and imaging studies.
- The baby was diagnosed with STD, received conservative management, and survived past the neonatal period, offering insights into this particular variant of the condition.
The increasing concern about global warming and the depletion of fossil fuel reserves has led to a growing interest in alternative energy sources, particularly fuel cells (FCs). These green energy sources convert chemical energy into electrical energy, offering advantages such as quick initiation, high power density, and efficient operation at low temperatures. However, the performance of FCs is influenced by changes in operating temperature, and optimal efficiency is achieved by operating them at their maximum power point (MPP).

Many women with late-stage ovarian cancer experience a recurrence and need subsequent treatment, even after initial therapy.

Methods: A retrospective review was performed of all adult UEPVI patients presenting to a level I trauma center between 1986 and 2019. Statistical analyses were performed to determine the independent predictors of mortality and hospital length of stay(LOS) among patients who underwent operative repair.
