A petrographic microscope is a type of optical microscope used to identify rocks and minerals in thin sections. The microscope is used in optical mineralogy and petrography, a branch of petrology which focuses on detailed descriptions of rocks. The method includes aspects of polarized light microscopy (PLM).
Both types of yeast foods above are rich in B-complex vitamins (besides vitamin B 12 unless fortified), [63] making them an attractive nutritional supplement to vegans. [93] The same vitamins are also found in some yeast-fermented products mentioned above, such as kvass. [95]

The IMF's definitive data for the past year and estimates for the current year are published twice a year in ...
In order to detect it, the aberrations of the microscope (like defocus) have to be tuned in a way that converts the phase of the wave at the specimen exit plane into amplitudes in the image plane. The interaction of the electron wave with the crystallographic structure of the sample is complex, but a qualitative idea of the interaction can ...
