Introductory chemistry (Nitz, Otto W.)

Introductory lecture: atmospheric chemistry in the Anthropocene.

The term "Anthropocene" was coined by Professor Paul Crutzen in 2000 to describe an unprecedented era in which anthropogenic activities are impacting planet Earth on a global scale. Greatly increased emissions into the atmosphere, reflecting the advent of the Industrial Revolution, have caused significant changes in both the lower and upper atmosphere. Atmospheric reactions of the anthropogenic...

Otto Loewi

The end of the 19th century was the starting point of many discoveries in the field of the neurophysiology. At that time, only basic technical approaches were available, and new discoveries depended on few results and lots of deductions. Furthermore, the scientific community was often debating on theoretical speculations and was often divided. I have chosen to present a German neurophysiologist...

Hexosamine-containing Glycoproteins of Normal Bovine Synovial Fluid* by Otto W. Neuhaus

Synovial fluid is usually considered to be a modified extracellular fluid or blood dialysate (1, 2). It is now well known that all of the electrophoretically classified groups of proteins found in serum are also, at least qualitatively, present in synovial fluid (3-8). This does not mean, however, that all proteins can pass the capillary membranes, because cholesterol and fats, usually associat...
