Department of trauma and orthopedics surgery. Mouwasat Hospital Dammam, 32263 Eastern Province Kingdom of Saudi Arabia.
Unlabelled: Introduction-Aim: Full-polyethylene glenosphere reverse shoulder arthroplasty (FP-RSA) known commonly as inverted-bearing concept utilizes a polyethylene glenosphere and metallic humeral liner. The aim was to assess mid-term outcomes of FP-RSA focusing on the incidence of scapular notching.
Methods: A retrospective analysis of 24 consecutive primary FP-RSA performed between 2017 and 2020 was conducted.
Analysis of bulletproof performance of structurally optimized ceramic composite armor through numerical simulation and live fire test.

This work aims to address key issues in the ballistic performance of ceramic-based composite armor, particularly at the joints of spliced bulletproof panels. The edge structure of C/C-SiC ceramic plates and ultra-high molecular weight polyethylene is redesigned to superimpose the joint areas. These structurally optimized composite pads are examined by numerical simulation of impact dynamics to understand their anti-penetration performance whose accuracy is then validated by live fire tests.

Department of Thermodynamics, Mechanical Engineering and Energy, University of Zagreb, Faculty of Chemical Engineering and Technology, Zagreb, Croatia.
The article discusses the importance of optimizing process parameters in 3D printing to achieve better mechanical properties of printed parts. It emphasizes the material extrusion 3D printing technology and some of the most commonly used materials, acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG). Optimizable process parameters such as, print angle, outer layer number, extruder flow ratio, extrusion (nozzle) temperature, and layer thickness are examined.

Naturally occurring gas clathrates are a significant methane resource-the primary component of natural gas, regarded as the cleanest hydrocarbon and a key feedstock for producing gray and blue hydrogen. Despite the global abundance of gas hydrate reserves, extraction via depressurization has yet to achieve commercially viable production rates. The primary limitation lies in the low permeability of hydrate-bearing sediments, where solid clathrates obstruct porous pathways, hindering dissociation and slowing gas recovery.

Purpose: Unicompartmental knee arthroplasty (UKA) is a viable option for localized osteoarthritis (OA) or avascular osteonecrosis with several advantages over total knee arthroplasty (TKA). UKA implants may feature a tibial component either all-polyethylene (AP) or metal-backed (MB). This study aims to retrospectively compare the clinical outcomes and survivorship of 74 UKAs over 16 years, focusing on comparing the results and survivorship of MB versus AP tibial tray.
