Effects of freeze-thaw cycles on fatigue performance of asphalt mixture and development of fatigue-freeze-thaw (FFT) uniform equation

Construction and Building Materials, 2020
Although it is widely recognized that freeze-thaw cycles can accelerate the performance deterioration and lead to premature failures of asphalt pavements, a quantitative understanding of how it affects the fatigue life is so far still lacking. This study

Fatigue and its impact on performance and health

British Journal of Hospital Medicine, 2023
An increasing body of evidence suggests that fatigue among healthcare staff is widespread, owing to a combination of high work intensity, long daytime hours and night-shift working. This has been linked to poorer outcomes for patients and longer inpatient stays, and to increased risks of work-related accidents, errors and injuries for practitioners ...

Muscular Performance and Fatigue in Primary Hyperparathyroidism

World Journal of Surgery, 2000
AbstractThe purpose of this study was to evaluate changes in muscular strength and endurance, work capacity, and subjective fatigue following surgical treatment of primary hyperparathyroidism (pHPT), and to assess whether changes in muscular function were due to changes in activation of the muscles.

Drillstring Fatigue Performance

SPE Drilling Engineering, 1990
Summary The life-prediction technique of a whole-life fatigue model was applied to drillstring components. Good agreement existed between the life predictions and the experimental data of drill collars. These life predictions were then used to study the effects of material properties and commonly used thread profiles on the fatigue life ...
