Development of and adherence to artificial gravity and resistive vibration exercises during 60 days of hypoxic 6° head‐down tilt bed rest: BRAVE study

Experimental Physiology, Volume 111, Issue 7, Page 3152-3172, 1 July 2026.
Abstract Artificial gravity (AG) combined with resistive vibration exercise has been proposed as a multi‐system countermeasure for long‐duration spaceflight; however, its operational feasibility during prolonged unloading remains insufficiently characterised.

Study of friction characteristics of a diesel engine running on different viscosity grade engine oils using conventional and acoustic emissions technique

Experimental studies were conducted on an off highway heavy duty diesel engine running on different viscosity grade engine oil, for determining the friction power in a firing engine by measuring the indicated mean effective pressure (IMEP) by in–cylinder
