Arthroscopy Techniques, EarlyView.Abstract Osteochondral lesions of the knee, particularly in patients with early osteoarthritic changes, remain a clinical challenge. The Agili‐C implant (CartiHeal, Smith & Nephew), an aragonite‐based osteochondral scaffold, offers a single‐stage, off‐the‐shelf solution designed to regenerate both cartilage and subchondral bone.

Active Stabilization of Multistage Axial-Compressor Aerodynamic System Instabilities [PDF]
Volume 5: Manufacturing Materials and Metallurgy; Ceramics; Structures and Dynamics; Controls, Diagnostics and Instrumentation; Education; IGTI Scholar Award; General, 1991 Active control of multistage axial-compressor aerodynamic instabilities has been studied analytically using a blade-row by blade-row compression system model. The instabilities considered are those which result from a global system instability.

High‐Temperature Heat Pump Test Bench with n‐Butane (R‐600) Generating Steam
Chemie Ingenieur Technik, EarlyView.This work involves building a test bench for a high‐temperature heat pump (HTHP) and analyzing the measurements. The focus is on steam generation using an HTHP to decarbonize process steam demand. The findings indicate that stable steam generation is possible, providing a higher heat transfer coefficient in the heat pump's condenser.
