There are many causes of chest pain. One is angina which results from inadequate oxygen supply to the heart muscle. Angina can be caused by coronary artery disease or spasm of the coronary arteries. Chest pain can also be due to a heart attack (coronary occlusion) and other important diseases.
Conclusions We have demonstrated here the significant effect of temperature on the conductivity measurements of solutions. This highlights the importance of maintaining standard and test solutions close to the reference temperature when taking measurements in order to obtain the most accurate conductivity values.
High conductivity materials conduct heat well. It is measured in watts per meter kelvin (W/(mÂ·K)). Thermal conductance is a measure of the ability of a material to transfer heat per unit time, given one unit area of the material and a temperature gradient through the thickness of the material.
