Experimental and Numerical Study on the Combustion and Emission Characteristics of Diesel and Ammonia in Dual Direct Injection Mode in an RCEM

Processes
Nowadays, the use of ammonia as a green fuel for internal combustion engines has attracted wide attention. The diesel/ammonia dual direct injection mode has shown great potential, but there is still a lack of basic research on injection strategies for this mode.

Leadership training in emergency medicine: A national survey. [PDF]

AEM Educ Train
Abstract Background Emergency medicine (EM) is a uniquely stressful environment in which leadership training could improve individual and team performance, patient outcomes, well‐being, and EM career intentions. The primary aim was to evaluate EM‐specific leadership training (EMLeaders) compared to no leadership training.
