While gynecomastia is the most common breast abnormality in men, other benign tumors that are common in women, such as fibroadenomas and papillomas, occur in men in rare occasions. According to the National Cancer Institute, the types of breast cancer most commonly diagnosed in men are similar to those found in women.
The compressibility factor (Z), also known as the compression factor, is the ratio of the molar volume of a gas to the molar volume of an ideal gas at the same temperature and pressure.It is a useful thermodynamic property for modifying the ideal gas law to account for the real gas behavior.igure 2 is an example of a generalized compressibility factor graph derived from hundreds of experimental PVT data points of 10 pure gases, namely methane, ethane, ethylene, propane, n-butane, i-pentane, n-hexane, nitrogen, carbon dioxide and steam.
Elasticity is a measure of responsiveness. The responsiveness of behavior measured by variable Z to a change in environment variable Y is the change in Z observed in response to a change in Y. Specifically, this approximation is common: elasticity = (percentage change in Z) / (percentage change in Y). The smaller the percentage change in Y is practical, the better the measure is and the closer it is to the intended theoretically perfect measure..
