Thermography in Experimental Cardiac Surgery
. Two electrodes were used for pacing and EG registration; one in an isolated area and the second in the intact atrium. Thermography was used to monitor progress during the procedure. Infrared technology revealed that comparing intra-arterial conductivity from the intact to the isolated areas showed

Putting Some Predictability into Wind Turbine Maintenance
the wear rate, so the brushes produce negligible. across the rotating interface in a slip ring assembly. A brush, or wiper, slides on a rotating. wear debris. And the multiple metal fi bers provide very good conductivity and very high. ring and maintains continual electrical contact during rotation

Cost and Energy Savings for a Factory Building after Modernizing the Heating System
insulation material with thickness of 25 mm has a low thermal conductivity of 0.09 W/m.K, at an. average operating temperature of the plate of 250°C. The temperature in the inner part of the HU1 is typically. around 470 °C. The thermal conductivity of the ceramic plates at this operating temperature

Save Energy With Fewer Oil Changes
and still surpass the 5,000-hr mark where petroleum-based oils start to degrade. PAOs have about 10% higher specific heat and 20% thermal conductivity than petroleum-based oils. This means equipment running on synthetics is better able to dissipate heat and run cooler for longer lubricant life. PAOs

Save Energy With Fewer Oil Changes
. PAOs can run 15,000 hr at 80 C or withstand temperatures of about 95 C and still surpass the 5,000-hr mark where petroleum-based oils start to degrade. PAOs have about 10% higher specific heat and 20% thermal conductivity than petroleum-based oils. This means equipment running on synthetics

Predictive Maintenance of Underground Heating Lines
. The increasing of thermal conductivity is caused by structural violation, humidity and permeability of insulator material. As a result the contact of tube metal with the soil will appear and sooner or later the corrosion will destroy tube wall. Heat anomaly can be a precursor of the future hot

DynaGuard Flexible Insulation Used in Rotory Kiln Applications (.pdf)
. First, dense refractories exhibit high thermal conductivity resulting. in elevated shell temperatures as the refractory is worn down over time, as well as high. energy consumption, a problem that greatly affects costs as fuel prices continue to escalate. Elevated temperatures outside the kiln also
