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.
Conductivity is a measure of waterâs capability to pass electrical flow. This ability is directly related to the concentration of ions in the water 1. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds 3.onductance is measured in mhos or siemens 19. Conductivity is the conductance (S) measured across a specified distance (1 cm), which is incorporated into the units (S/cm) 19. As such, the conductance of water will change with the distance specified.
