The thermoneutral zone: implications for metabolic studies.
A thermoneutral environment is important for many human physiological studies. The thermoneutral zone (TNZ) is defined as the range of ambient temperatures without regulatory changes in metabolic… Expand
Validation of an individualised model of human thermoregulation for predicting responses to cold air

- 1 December 2006
We study the properties of a hard-sphere dense gas near the hard walls of micro and nano-channels. Analytical techniques, Monte Carlo (MC) methods and molecular dynamics (MD) simulation methods have… Expand
Cold-induced vasoconstriction at forearm and hand skin sites: the effect of age

During mild cold exposure, elderly are at risk of hypothermia. In humans, glabrous skin at the hands is well adapted as a heat exchanger. Evidence exists that elderly show equal vasoconstriction due… Expand
Incorporating neurophysiological concepts in mathematical thermoregulation models

Skin blood flow (SBF) is a key player in human thermoregulation during mild thermal challenges. Various numerical models of SBF regulation exist. However, none explicitly incorporates the… Expand
Physiological modeling for technical, clinical and research applications.
Various and disparate technical disciplines have identified a growing need for tools to predict human thermal and thermoregulatory responses to environmental heating and cooling and other thermal… Expand
Numerical simulation of deformations and electrical potentials in a cartilage substitute.
Cartilage exhibits a swelling and shrinking behaviour that influences the function of the cells inside the tissue. This behaviour is caused by mechanical, chemical and electrical loads. It is… Expand
