A concept is developed and described which allows to measure the heat capacity and the effective thermal conductivity of stable and undercooled liquid metals and alloys in an electromagnetic levitation apparatus. We propose to use an ac pulse heating method which is used nowadays as a standard technique for precision measurement of low temperature heat capacities. The ideal process parameters i...

Hemolysis was used as an endpoint for the measurement of damage to the plasma membrane in human erythrocytes after a single or a double heat shock. The thermotolerance of erythrocytes is a transitional phenomenon, reaching its maximum at a 3-hour incubation at 37 degrees C between the heat shocks.

An inverse source problem for the heat equation is considered. Extraction formulae for information about the time and location when and where the unknown source of the equation firstly appeared are given from a single lateral boundary measurement. New roles of the plane progressive wave solutions or their complex versions for the backward heat equation are given. AMS: 35R30, 80A23

A relatively new technology for calorimetry has recently been discussed for practical use and since then marketed by PerkinElmer under the name HyperDSC®. The detailed characteristics and use of this new mode of measurement, which represents a major step forward in Fast Scanning Calorimetry (FSC) as compared to Standard DSC, have been published.1-4 Controlled and constant scan rates of hundreds...

1. A calorimeter for the continuous measurement of heat production and heat loss in the human subject, for at least 24 h, is described. The calorimeter operated on the heat-sink principle for direct calorimetry and an open-circuit system for indirect calorimetry. 2. Sensible heat loss was measured using a water-cooled heat exchanger, and the temperature of water entering the heat exchanger was ...
