Mechanistic studies on the ring-opening polymerisation of D,L-lactide with zinc guanidine complexes
The increasing shortage of resources has enforced the search for production techniques for biodegradable polymers made of renewable raw materials. An example is polylactide (PLA), an aliphatic polyester, which can be obtained by the metal-catalysed ring-opening polymerisation (ROP) of lactide (Fig. 1). The monomer for PLA production is available from corn or sugar beets by a bacterial fermentat...
متن کاملPharmacological studies on fatigue. I.
Considerable investigation has been done as to whether or not a particular drug is effective for recovery of an animal after it has become exhausted. Experiments have included screening antifatigue effect on animals, but applications have not been generally established. Effects of drugs on psychological fatigue as seen in man can hardly be inferred from tests on animals. Even physiological effe...
متن کاملStudies on Mexican Typhus Fever. I
The preceding studies on typhus fever, chiefly done with a Mexican strain obtained from Dr. Mooser, concern themselves largely with reinvestigations of some of the fundamental problems of this disease. Filtration experiments carried out with methods almost regularly successful with true filterable viruses, in regard to material, suspension fluid, reaction, nature of filters and pressure employe...

متن کاملStudies on the Venous Pulse. I
A wave is described occurring in the venous pulse of man late in the diastolic period. This wave is a diastolic wave, since in an increase in length of the cardiac cycle it follows the h wave at its regular interval and becomes separated from the a wave of the next cardiac cycle. There is no wave on the venous pulse in man which can be referred to a contraction of the region of the great veins ...
