Some cosmochemical problems: Notes on the thirty-seventh annual Priestley lectures (Urey, Harold C.)

Harold Urey

It was on Thanksgiving day in 1931 that Harold Clayton Urey found definitive evidence of a heavy isotope of hydrogen. Urey's discovery of deuterium is a story of the fruitful use of primitive nuclear and thermodynamic models. But it is also a story of missed opportunity and errors—errors that are particularly interesting because of the crucial positive role that some of them played in the disco...

More on Configurations in Priestley Spaces, and Some New Problems

Prohibiting configurations (≡ induced finite connected posets) in Priestley spaces and properties of the associated classes of distributive lattices, and the related problem of configurations in coproducts of Priestley spaces, have been brought to satisfactory conclusions in case of configurations with a unique maximal element. The general case is, however, far from settled. After a short surve...

Twenty-Seventh Annual Conference on Shock

Sepsis constitutes the main cause of death at intensive care units worldwide. Although an ample variety of physiopathology-based experimental therapies has been tested in the last 20 years only activated protein C (drotrecogin alfa) has shown to improve outcome for selected patients. Therefore, the first line of treatment remains to be antibiotic therapy along with hemodynamic, ventilatory and ...
