Haemodynamic responses to heat stress and hypohydration in resting and exercising humans: Implications for the regulation of skeletal muscle blood flow
Heat stress-induced hyperthermia and exercise-induced hypohydration are associated with marked alterations in limb and systemic haemodynamics in humans. However, the mechanisms underlying these alterations their effects on muscle blood flow are not well understood. The present thesis examined …

The Screenplays and Films of Lawrence Kasdan
… of his first two films as writer-director, Body Heat (1981) and The Big Chill (1983). Chapter four interrogates Kasdan’s position as the ‘archetypal’ baby-boomer filmmaker, examining the values expressed in his films that make him so representative of America’s largest ever demographic. …

The Effects of Heat and Cold on Cognitive Function and Endurance Capacity
… may be due to early perturbations in whole-body heat balance where the change in skin temperature (even before measurable changes in core temperature) impair performance, followed by greater impairments with changes in core temperature. However, the separate and combined effects of changes …

Adenosine receptors in cutaneous thermal hyperemia and active vasodilation in humans
… cutaneous vasodilation response to local skin heating and whole body heating in humans remain unresolved. Although nitric oxide (NO) is known to contribute to these responses, it remains unclear as to the source of NO. Adenosine receptors induce vasodilation in many human tissues and may work, …
