But, if you are serious about learning Italian - and even before you buy or subscribe to any expensive courses (except, obviously, GamesforLanguage.com's Italian Story, which is FREE!) - you may want to learn more about Benny's approach by clicking on his explanation of Why Italian is easy!.
Coefficient of thermal expansion. The coefficient of thermal expansion describes how the size of an object changes with a change in temperature. Specifically, it measures the fractional change in size per degree change in temperature at a constant pressure. Several types of coefficients have been developed: volumetric, area, and linear.
The importance of mounting medium refractive index. If you want to observe a specimen under the microscope, then you have to add a mounting medium. The mounting medium is important for several reasons. Of course it stabilizes and preserves the specimen. But at least equally important are the optical characteristics.The refractive index (RI) of the mounting medium can have a significant impact on the image quality.he mounting medium is important for several reasons.
