Inflammatory Microenvironment-Responsive Hydrogels Enclosed with Quorum Sensing Inhibitor for Treating Post-Traumatic Osteomyelitis. [PDF]

Adv Sci (Weinh)
Inflammatory microenvironment targeted hydrogel promotes osteogenesis and inhibits inflammation in post‐traumatic osteomyelitis by responding to severe oxidative stress or acid abscess environment, and subsequently releasing quorum sensing inhibitors. It can inhibit “bacteria‐to‐bacteria communication” to clear planktonic bacteria and biofilms, reduce ...

Assessment of microbial biocontrol agent (BCA) viability to mechanical and thermal stress by simulating spray application conditions

Pest Management Science, Volume 79, Issue 11, Page 4423-4438, November 2023., 2023
The spray mixture residual amount in the tank affects its temperature increase rate. Only temperatures >35 C° were detrimental for BCAs. BCA viability is affected mostly by thermal rather than mechanical stress. Abstract Background In order to improve the biological control agent (BCA) efficacy, stress factors threatening the viability of ...

The contribution of low‐head pumped hydro storage to grid stability in future power systems

IET Renewable Power Generation, Volume 17, Issue 14, Page 3594-3608, 26 October 2023., 2023
The low‐head PHS system developed in ALPHEUS project will introduce a new storage system. This system will serve as new flexibility option contributing to the security of supply and grid stability with the advantage to provide vital ancillary services, specially frequency control, and thus, promoting the energy transition in the EU.

Comprehensive lumped parameter and multibody approach for the dynamic simulation of agricultural tractors with tyre–soil interaction

IET Cyber-Systems and Robotics, Volume 5, Issue 3, September 2023., 2023
Abstract Modern agricultural tractors are complex systems, in which multiple physical (and technological) domains interact to reach a wide set of competing goals, including work operational performance and energy efficiency. This complexity translates to the dynamic, multi‐domain simulation models implemented to serve as digital twins, for rapid ...
