A study by Henning et al., showed low distress in married medical students.23 Similarly, another cross-sectional study by Lloyd and Musser exhibited mean stress scores to be minimum in married medical students compared to non-married.24 The study has limitations based on its small sample size and study design.
In LCF experiments, various aspects of analysis like cyclic stress response curve, hardening behavior, and Masing and non-Masing characteristic were carried out, whereas ratcheting behavior of the material has been described in terms of ratcheting strain accumulation response curve, hysteresis loop area, ratcheting strain rate, and plastic strain amplitude with a variation of mean stress and stress amplitudes.
Here [[sigma].sub.m] = ([[sigma].sub.max] + [[sigma].sub.min])/2 is the mean stress of the cycle, [[sigma].sub.a] = ([[sigma].sub.max] - [[sigma].sub.min])/2 is the amplitude of the stress.
A significant reduction in mean stress scores was obtained for most of the parameters, except anger and frustration where quantitative estimation did not show any significant difference.
There are many factors that can influence the fatigue behavior of composite materials, such as the stress amplitude, the mean stress, the performances of material component, the loading frequency, interfacial property, and so on [8-10].
The mean stress vulnerability score was 51 with the range from 30 to 71.
The presentation included clinical data from all 18 patients completing 12 weeks of enobosarm treatment, which, as previously reported, demonstrated an 81% reduction in the number of mean stress leaks per day, the primary endpoint of the clinical trial, as well as additional data demonstrating duration of response following completion of treatment, including nine patients who have now reached seven months post-treatment.
[10-14] Other studies have also compared the stress levels in medical and other degree programs and found maximum mean stress scores for medicine.
The relationship between deviatoric stress q and mean stress p is depicted in Figure 2, which indicates that the strength increases first and then decreases with increasing mean stress p.
The mean stress to which a particular member is subjected to is a combination of the oscillatory fatigue stress caused by transient loads and the permanent stress caused by dead loads.
Although the difference was not statistically significant, the present study reported that workplace stress was higher among anaesthetists (mean stress level 18.9) and lower among residents (mean stress level 11.5).
