Reflex vasodilation is attenuated in aged skin during hyperthermia. We used laser-Doppler imaging (LDI) to test the hypothesis that the magnitude of conductance and the spatial distribution of vasodilation are altered with aging. LDI of forearm skin was compared in 12 young (19- to 29-yr-old) and 12 older (64- to 75-yr-old) men during supine passive heating. Additionally, iontophoresis of brety...

To detect a ramp and guide a tracked robot to complete the ramp-climbing task in an unknown environment, four tracked robot control modes are proposed in this paper. The modes are the exploration mode, aligning mode, calculating the tilt angle mode, and climbing mode. This self-made tracked robot only equips with a Kinect depth sensor; unfortunately, the sensing depth data, in general, incorpor...

The instability of supersonic compression ramp flow is investigated. It is assumed that the Reynolds number is large and that the governing equations are the unsteady triple-deck equations. The mean flow is first calculated by solving the steady equations for various scaled ramp angles α, and the numerical results suggest that there is no singularity for increasing ramp angles. The stability of...

in italy, several policy measures have been implemented in order to increase energy efficiencyand reduce carbon emissions especially concerning the household sector. however, in order to design andimplement these policy measures efficiently, it is necessary to get a better understanding of the factorsinfluencing household energy behavior. in this paper, by using disaggregated data from the 2009...

Gas chromatography is an analytical technique for separating and analyzing individual components in a gas mixture. Temperature programming is a form of gas chromatography in which the column temperature is controlled to follow a specific heating rate, dwell time and cooling rate during the course of the analysis. Temperature programming enables separation of a wider range of components, when co...

This research focusses on the facies distribution, paleoenvironment and paleoecology of the foraminifera of the Guri Member in the northern Bandar Abbas Hinterland located in the Roydar area of southern Iran. The Guri Member is 570 meters thick and composed of limestone, argillaceous limestone and marl. The distribution of the foraminifera in the study area indicates the existence of three bioz...

The general objectives of our research, presented in this series of papers, were to develop a computational model of the brain stem respiratory neural network and to explore possible neural mechanisms that provide the genesis of respiratory oscillations and the specific firing patterns of respiratory neurons. The present paper describes models of single respiratory neurons that have been used a...
