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.
CONCLUSION This paper presented the results of a study that analyzed the effect of temperature on PIN diode forward bias resistance. It showed that the carrier lifetime temperature coefficient is the primary mechanism that determines temperature performance and that this coefficient for any particular diode depends on the diode geometry and passivation material.
