Perpetual Pavements, if properly designed and rehabilitated, it can last longer than 50 years without major structural rehabilitation. Fatigue endurance limit is a key parameter for designing perpetual pavements to mitigate bottom-up fatigue cracking. The endurance limit has not been implemented in the Mechanistic Empirical Pavement Design Guide software, currently known as DARWin-ME. This study was conducted as part of the National Cooperative Highway Research Program (NCHRP) Project 9-44A to develop a framework and mathematical methodology to determine the fatigue endurance limit using the uniaxial fatigue test. In this procedure, the endurance limit is defined as the allowable tensile strains …

ABSTRACT Nursing physical fatigue is a critical issue that may lead to degradation of care delivery and ultimately result in medical errors. This issue is equally relevant due to the looming shortage of nurses, which has been linked to the physical demands and potential occupational hazards intrinsic to the profession; as well as to the graying of the nursing workforce who experiences gradual loss of strength and agility that accompanies aging as time in the career advances. In a hospital Emergency Department, the level of nursing physical fatigue can potentially reach its threshold in light of challenging workloads, scope of …
