The Council also conceptualized fatigue as either primary (intrinsic to the MS disease process) or secondary to chronic illness factors, such as medication, depression or poor sleep. Distinctive features of MS fatigue The nature of MS-related fatigue can be distinguished from other types of fatigue...
The stress axis can also be either the stress amplitude (σmax ‒ σmin)/2, the stress range (σmax ‒ σmin) or mean stress (σmax + σmin)/2 and it is generally seen that the fatigue life depends weakly on the R ratio (R = σmin/σmax), where σmax and σmin represent...
ERP waves comprise a series of positive and negative voltage deflections related to several underlying perceptual, motor, and cognitive components, and components are referred to by a letter (P or N) that indicates polarity (positive or negative) and by a number that indicates either the latency...
In addition, either the stress-life or strain-life method can be combined with the fatigue crack growth method to consider both crack initiation and all growth stages inherent to the fatigue process – and this is the so-called ‘two-stage model’ [111]. 3.2.2 Fatigue crack initiation Low...

2a,b. For both global compression-compression and global tension-tension, the local maximum tensile stress σ1 is a fluctuating tensile stress with R = 0.1 and high local tensile stresses occur on either the upper of lower side of a strut-node connection. For tension-compression, σ1 ...
My hope is that thiamine can be just as helpful for my readers. The Takeaway Often, people with Hashimoto’s will be started on thyroid hormones but will continue to feel tired. Fatigue is a common symptom of an underactive thyroid, but it’s also a symptom of many other associated condit...
Either because it is too tedious or because it is too difficult, we shirk it. And the longer we postpone it, the more tired we feel. Such start-up fatigue is very real, even if not actually physical, not something in our muscles and bones. The remedy is obvious, though perhaps ...
[20]. It was shown that different types ofFRPcomposites yielded different positions and slopes of the curves in the double logarithmic plot of delamination rate da/dNas a function of applied ‘load’ (either expressed as aGmaxor a ΔGvalue) and could, hence, be discriminated. Displacement ...
based on the combination of places where the emotional face and dot appeared: the dot appeared either on the same (congruent) or the opposite (incongruent) side as the emotional face; each condition was displayed with equal probability. Furthermore, the emotional faces (happy, sad, and angry)...
