This article provides plain and handy expressions to decide the most suitable analytical model for the thermal analysis of the ground source in vertical ground-coupled heat pump applications. We perform a comprehensive dimensionless analysis of the reciprocal deviation among the classical infinite, finite, linear and cylindrical heat source models in purely conductive media. Besides, we complet...

We analyzed whether burnout and vital exhaustion or job-related chronic stress is associated with hypothalamic-pituitary-adrenal (HPA) axis dysregulation in school teachers (N=135; 25-63 years; mean age 46.1+/-9.20 years). Participants collected seven saliva samples (0, 30, 45, and 60 min after awakening, 11a.m., 3 p.m., 8 p.m.) on 2 working days, 1 leisure day, and after pre-medication with 0....

Adequate energy management during the working day is essential for employees to remain healthy and vital. Research has investigated which energy management strategies are frequently used and which are most beneficial, but the results are inconclusive and research is still scarce. We aim to extend the current knowledge by considering individual differences in terms of working compulsively (as ke...

CONTEXT Studies of burnout among allopathic physicians have shown many deleterious effects for both physicians and patients. To our knowledge, no studies have quantified burnout among osteopathic physicians. OBJECTIVE To determine the prevalence of burnout, mentoring, and resident training satisfaction among US osteopathic otolaryngology residents compared with previously published data for a...

The current research drew upon the resource perspective (Grzywacz & Marks, 2000; ten Brummelhuis & Bakker, 2012) and firstly focused on the reciprocal mediation relationship between schedule control, work interference with family (WIF) and emotional exhaustion. First, the present study proposed that WIF mediates the negative relationship between schedule control and emotional exhaustion, and em...

Several recent studies have reported the phenomenon of software aging, where the state of the system degrades with time due to exhaustion of operating system resources, data corruption and numerical error accumulation. This eventually leads to performance degradation or crash/hang failure of the software. In this paper, we propose a measurement-based performability model to estimate the rate of...

CMAJ Tens of thousands of victims of Hurricane Katrina in the US Gulf Coast states are psychologically scarred from the trauma and will need help, says a Canadian emergency physician who travelled to Louisiana as part of Vancouver's Urban Search and Rescue team. "Many of the people that we saw had this vacant stare in their eyes," Dr. Mike Flesher, 44, told CMAJ. "They were mentally and physica...

When psychological and physiologic adaptation mechanisms become dysfunction to environment induced a period of elevated heat stress, heat-related emergencies occur. Heat-related illness may be trivial to life threatening. They represent a continuum of disorders such as heat edema, prickly heat, heat cramps, heat tetany, heat syncope, and heat exhaustion to critical disease well known as heat st...

Molasses exhaustion has been investigated in South Africa since 1949, and Bruijn et al. (1972) applied a laboratory exhaustion procedure which has since been used extensively (Rein and Smith, 1981). The same approach and equipment have been used to investigate the effect of selected impurities on molasses exhaustion. These impurities include fructose, glucose, inorganic ash constituents, such a...
