OBJECTIVES This study draws from the resource depletion and conservation theories to develop a process model of informal caregiving. The model includes the burnout as a key mediator of the relationship between benefit/threat appraisals and critical outcomes including perceived physical health, depression and life satisfaction. METHODS A self-report questionnaire was utilized to collect releva...

Accepted 27 September 1995 An 81-year-old man, resident of a poorly ventilated, ineffectively air-conditioned inner city apartment, presented during a heat wave (environmental temperature 80°-93°F and humidity 70%-80%) with hyperthermia, confusion and dehydration. The patient had mild hypertension, depression and urinary incontinence and was taking hydrochlorothiazide/methyldopa, nortriptyline ...

OBJECTIVES To examine the incidence, clinical state, personal risk factors, haematology, and biochemistry of heat exhaustion occurring at a deep underground metalliferous mine. To describe the underground thermal conditions associated with the occurrence of heat exhaustion. METHODS A 1 year prospective case series of acute heat exhaustion was undertaken. A history was obtained with a structur...

During the summer of 1985, 45 soldiers with heat illness were admitted to the British Military Hospital, Hong Kong. Twelve had severe heat stroke, the remainder heat exhaustion. This paper discusses the management and prevention of heat illness in the military context.

Heat stroke in athletes is entirely preventable. Exertional heat illness is generally the result of increased heat production and impaired dissipation of heat. It should be treated aggressively to avoid life-threatening complications. The continuum of heat illness includes mild disease (heat edema, heat rash, heat cramps, heat syncope), heat exhaustion, and the most severe form, potentially lif...

The aim of this study was to test the hypothesis that adding caffeine to postexercise carbohydrate (CHO) feedings improves subsequent high-intensity interval-running capacity compared with CHO alone. In a repeated-measures design, 6 men performed a glycogen-depleting exercise protocol until volitional exhaustion in the morning. Immediately after and at 1, 2, and 3 hr postexercise, participants ...

The effect of metabolic heat generation on the freezing of biological tissue has been studied. Quasi-steady approximation is used to solve the Pennes bioheat equation in tissues. Temperature profile and motion of freezing interfaces are obtained for different values of metabolic heat generation. It is observed that metabolism has a significant effect on freezing of biological tissues during cry...

This research examined a model in which experience of privacy served as a mediator between architectural privacy and emotional exhaustion in the workplace and personalization of one’s workspace served as a moderator, mitigating the adverse effect of low levels of experienced privacy at work on emotional exhaustion. The results generally supported our hypotheses by indicating that in its role as...

We study the use of the Evans nonequilibrium molecular dynamics (NEMD) heat flow algorithm for the computation of the heat conductivity in one-dimensional lattices. For the well-known Fermi-Pasta-Ulam model, it is shown that when the heat field strength is greater than a certain critical value (which depends on the system size) solitons can be generated in molecular dynamics simulations startin...

The ground thermal properties and the heat-transfer efficiency of the borehole heat exchanger (BHE) system are key parameters for designing ground-coupled systems. Proper design of such systems requires good knowledge of these parameters, providing an efficient and economic operation. For this purpose a test procedure known as Thermal Response Test (TRT) was developed in 1996 at the Oklahoma St...
