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.
Temperature reproducibility Over a period of days, thermal cycling of capacitance sensors can provide variations in their capacitance/temperature values equivalent to several tenths of a degree at 4.2 K, 77 K, and room temperature. Over longer periods of time, variations can reach one degree or more. However, any reduced capacitance,
