Hypothermia can be treated using an external heat source, with several systems available including circulating hot water blankets, blowing air systems, electric pads, bubble wrap or infrared lamps.
Using an external heat source (150°C), the time to increase the sub-occlusal pulp temperature by 5,5°C varied between 3.5 and 39 seconds in the individual pulp positions, i.e. a mean value of 16 seconds (median 13.5 s).
The experiment used an external heat source (CO2 laser) to rapidly heat the surface of HMX and observe the response upon application of EM energy that, on its own, is not enough power to induce heating or ignition.
Making a fully functioning Stirling engine made solely by AM was a logical starting point as they use an external heat source and don't require precision machined parts like valves and injectors.
Use an external heat source to help warm the body of the person showing signs of hypothermia.
Core body temperature was maintained at 35 ± 0.5°C using an external temperature controlled heat lamp.
During the non-data acquisition times, the probe was heated using an external current, so minimising deposition of an insulating layer on its surface.
After the iron particles are taken up by the cell, they can be heated by using an external magnetic field that produces exactly the desired temperature inside the tumor cell for just the right amount of time.
Magnetic nanoparticles can bind to drugs, proteins, enzymes, antibodies, or nucleotides and can be directed to an organ, tissue, or tumour using an external magnetic field or can be heated in alternating magnetic fields for use in hyperthermia.
You're far better off using an external windshield.
