The use of cyclic triaxial tests in the characterization of portuguese UGM

, 2008
Coarse aggregate is widely used in the unbound granular layers (UGM) of roads, in particular as granular sub-base and base. However, although various studies have been conducted on these materials, their mechanical behaviour still has not been properly characterized, in Portuguese conditions, especially due to reasons connected to the heterogeneity of ...

Acute Sleep Deprivation Shifts Substrate Utilization Toward Greater Fat Oxidation During Incremental Exercise in Recreationally Trained Adults

Scandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 6, June 2026.
ABSTRACT Sleep deprivation alters metabolic homeostasis and substrate metabolism, but its effect on fat and carbohydrate utilization during exercise is unclear. This study examined the effects of one night of total and partial sleep deprivation on substrate utilization during a maximal fat oxidation test (MFO) in recreationally trained adults.
