Analysis of Resistance to Wind Suction of Flat Roof Coverings Glued with Polyurethane Adhesives.

The article analyses the impact of wind suction on roof coverings glued with polyurethane adhesives to flat roofs, i.e., roofs with an up to 20% slope.

[Oxygen partial pressure, oxyhemoglobin saturation and the oxygen content of blood in endotoxic shock].

Our research showed in the endotoxic shock no fundamental and durable changes with reference to oxygen partial pressure and oxyhemoglobin saturation of the arterial blood within the first two hours. On the other hand the oxygen contents of the arterial blood decreased progressively in connection with the progressive decrease of hemoglobin. In detail the arterial oxygen partial pressure decreased within the first 30 minutes after the endotoxin injection and normalized itself by the sixtieth minute, afterwards it remained stationary.
