Drawing Course List
Studies of the nude in western art dates back to the ancient Greeks and, in more modern times, to the 1400's, the period known as the Renaissance. Drawing the nude is the ultimate exercise in learning to see line, proportion and form, and students' ability to deal with these fundamentals of drawing will be greatly enhanced in this course.

Mica seems to show the lowest concentration in the ABw horizon. Chlorite, mica, feldspar, quartz and traces of amphibole were also found in the gneiss (rock sample of the river bank) and the rock fragments in the soil. Some variability could be measured regarding the mica and chlorite proportion (Fig. 8).

MHC class I chain-related protein A and B (MICA and MICB) …
We observed co-localisation of CD63 with MICA/B in all tumour samples, raising the possibility that at least a small fraction of intracellular MICA/B may be released through exosomes. However, co-localisation with CD107a was more abundant showing that a good proportion of MICA/B is localised in lysosomes and could be targeted for degradation.

This is because the orthogneiss protolith has a lower mica proportion than the metapelite. Therefore, the complete breakdown of muscovite and biotite for the orthogneiss occurs at relatively low temperature of ~ 730 °C and produces ~ 10 wt% melt enriched in Li. By comparison, biotite-out for the metapelite occurs around 825 °C at 7 kbar and ...
