The paper contains an assessment of the sylphons lifetime for multiaxial fatigue. Three criteria were used two based on s � N diagram and one based on energy. For a more accurate determination of the sylphons lifetime the stress and the strain distribution been determined using FEM, the tensile curve of the steel W 4541 at elevated temperature.

Abstract A simple colorimetric method for the determination of acetaminophen is described. The method is based on the measurement of a crimson complex formed when acetaminophen is treated with 10% sodium hydroxide solution at elevated temperature. Compounds such as phenacetin, aspirin, caffeine, oxyphenbutazone, barbiturates, hydantoins, and dextropropoxyphen which are present in various formulations containing acetaminophen do not interfere. The method is sensitive to concentrations as low as 25 μg acetaminophen/mL.
