The thermoneutral zone: implications for metabolic studies.

Boris R. M. Kingma, Arjan J. H. Frijns, Wouter D. van Marken Lichtenbelt
Frontiers in bioscience
2012

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… (More)

Molecular Dynamics and Monte Carlo Simulations for Heat Transfer in Micro and Nano-channels

Arjan J. H. Frijns, Silvia V. Nedea, Albert J Markvoort, Anton A. van Steenhoven, Peter A. J. Hilbers
International Conference on Computational Science
2004

There is a tendency to cool mechanical and electrical components by microchannels. When the channel size decreases, the continuum approach starts to fail and particle based methods should be used. In… (More)

Increased systolic blood pressure after mild cold and rewarming: relation to cold-induced thermogenesis and age.

Boris R. M. Kingma, Arjan J. H. Frijns, Wim H. M. Saris, A. A. van Steenhoven, W D van Marken Lichtenbelt
Acta physiologica
2011

AIM Higher winter mortality in elderly has been associated with augmented systolic blood pressure (SBP) response and with impaired defense of core temperature. Here we investigated whether the… (More)

Measurement of model coefficients of skin sympathetic vasoconstriction.

Natascha M. W. Severens, Wouter D. van Marken Lichtenbelt, Arjan J. H. Frijns, Boris R. M. Kingma, Bas A. J. M. de Mol, A. A. van Steenhoven
Physiological measurement
2010

Many researchers have already attempted to model vasoconstriction responses, commonly using the mathematical representation proposed by Stolwijk (1971 NASA Contractor Report CR-1855 (Washington, DC:… (More)

Development of EEM based silicon-water and silica-water wall potentials for non-reactive molecular dynamics simulations

Beyond the classic thermoneutral zone

Boris R. M. Kingma, Arjan J. H. Frijns, Lisje Schellen, Wouter D. van Marken Lichtenbelt
Temperature
2014

The thermoneutral zone is defined as the range of ambient temperatures where the body can maintain its core temperature solely through regulating dry heat loss, i.e., skin blood flow. A living body… (More)

Energy efficient living-INTEWON : From measuring to modelling to managing

Boris R. M. Kingma, Christel M C Jacquot, +4 authors Wouter D. van Marken Lichtenbelt
2012

In 2011, a Dutch multidisciplinary project was launched entitled "Individual-oriented information technology for energy efficient living" (INTEWON). It is a four-year study aimed at gaining more… (More)

Hybrid method coupling molecular dynamics and Monte Carlo simulations to study the properties of gases in microchannels and nanochannels.

Silvia V. Nedea, Arjan J. H. Frijns, A. A. van Steenhoven, Albert J Markvoort, Peter A. J. Hilbers
Physical review. E, Statistical, nonlinear, and…
2005

We combine molecular dynamics (MD) and Monte Carlo (MC) simulations to study the properties of gas molecules confined between two hard walls of a microchannel or nanochannel. The coupling between MD… (More)

Self-organized twinning of actuated particles for microfluidic pumping

• A submitted manuscript is the author's version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published… (More)

Physiological modeling for technical, clinical and research applications.

Dusan Fiala, Agnes Psikuta, +4 authors Arjan J. H. Frijns
Frontiers in bioscience
2010

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… (More)
