Comparative effectiveness of supination-flexion and hyperpronation maneuvers in radial head subluxation: A systematic review and meta-analysis.

Study Objective: Radial head subluxation (RHS) is a frequent upper extremity injury in preschool children. Although the supination-flexion method is traditionally used for reduction, the 2017 Cochrane Review systematic review has shown that the hyperpronation maneuver is more successful. Despite the Cochrane Review suggesting that hyperpronation could be the preferred first-line technique in clinical practice, the studies analyzed have been deemed to carry a high risk of bias due to various methodological issues.

Optimizing Charge Transport Layers to Enhance the Performance of Lead-Free RbGeI Perovskite Solar Cells: A Comprehensive Analysis of ETL and HTL Engineering.

This study investigates innovative hybrid perovskite solar cells using rubidium-germanium-iodide (RbGeI) as the substrate, incorporating various hole transport layers like CuO, CuO, and SnSe, and wide-bandgap chalcogenide electron transport layers (ETLs) like IGZO, WS, InS, and ZnSe. After selecting IGZO as the optimal ETL, its depth was optimized using the SCAPS-1D simulator to evaluate device performance. Three device configurations were examined: device-I (Al/FTO/IGZO/RbGeI/CuO/Ni), device-II (Al/FTO/IGZO/RbGeI/CuO/Ni), and device-III (Al/FTO/IGZO/RbGeI/SnSe/Ni), with a detailed analysis of the doping concentration, thickness of the layer, density of defect, operational temperature, and interface defects.

Evaluation of a Low-Cost Amplifier With System Optimization in Thermoacoustic Tomography: Characterization and Imaging of Ex-Vivo and In-Vivo Samples.

Microwave-induced thermoacoustic tomography (TAT) is a hybrid imaging technique that combines microwave excitation with ultrasound detection to create detailed images of biological tissue. Most TAT systems require a costly amplification system (or a sophisticated high-power microwave source), which limits the wide adoption of this imaging modality. We have developed a rotating single-element thermoacoustic tomography (RTAT) system using a low-cost amplifier that has been optimized in terms of microwave signal pulse width and antenna placement.

Comparative energy demand and carbon footprint analysis of textile waste management systems in Australia.

In modern societies, especially in developed countries, textile waste management has become a critical issue due to overconsumption and throw-away culture. This case study aims to develop a comprehensive quantitative energy demand and carbon footprint analysis model using CCalC2 software to identify the most sustainable end-of-life management practices for the textile waste in Australia, the second-largest consumers of textile products. Results of this study showed that chemical recycling is the best option from the standpoint of saving pulp production energy and recycled pulp material, while it is a carbon-intensive process (6401 kg COeq/1000 kg).

Evolution of long COVID over two years in hospitalised and non-hospitalised survivors in Bangladesh: a longitudinal cohort study.

Background: In developing settings, comparative data on COVID hospitalised survivors (HS) and non-hospitalised survivors (NHS) is scarce. We determined burdens, incidence, evolution, and associated factors of long COVID-19 over two years among these groups.

Methods: We conducted a longitudinal cohort study in Dhaka, Bangladesh, and recruited confirmed COVID-19 survivors from December 2020 to May 2021 (previously reported).
