While much attention has been paid to the structural changes which accompany the dehydration of kaolinite (Brindley & Nakahira, 1959; Freund, 1967, 1972; Chakraborty, 1979), the early stages of dehydration have not been studied so extensively (Fripiat & Toussaint, 1963). One question of quite broad interest is that of proton mobility. The question arises from the seemingly paradoxial observatio...

With Dr. Fischer's long interest in muscle physiology and with his background in Germany, I thought that my personal experiences in Professor Otto Meyerhof's laboratory in Heidelberg, 1931-1932, might be of interest. This laboratory was at that time one of the outstanding centers for research in muscle physiology and chemistry. The laboratory was called the Kaiser Wilhelm-Institute fiir Medizin...

Professor Dr. Karl Nickel, one of the founding fathers of interval computations in Germany, died on January 1, 2009, a couple of weeks before his 85th birthday. Karl Nickel, professor emeritus of mathematics at the Albert-Ludwigs-Universität in Freiburg, Germany, was born in 1924 in Tübingen. As with most young people of his age, he had to fight in the war. After being released as a prisonerof-...

is set out in a conventional way, each bodily system having a chapted given to it. There is also a chapter on the units of measurement needed to describe physical quantities. On first inspection, the text and diagrams look very familiar and to a certain extent the approach to each facet is quite conventional. No subject is treated in a very superficial manner. However, I suspect that the beginn...
