A study was made of the methyl sterols involved in sterol biosynthesis in developing rat brain. In addition to the determination of the endogenous sterols present in 15-day-old rat brain, experiments were conducted to establish which of these sterols could be labeled by a minced tissue preparation in the presence of [Z-W]mevalonic acid. The turnover of [14C]lanostero1, [4-3H]squalene oxide, and...

Oxide dispersion strengthened (ODS) alloys with a high content of Al are candidate materials for extreme temperature applications such as turbine blades and other components working at temperatures significantly above 1000 °C. While oxidation kinetics Fe–Al ODS steels is frequently studied, the stability growth strengthening oxide rarely studied topic. The Fe-10Al-4Cr-4Y2O3 an experimental mate...

In a creep damage analysis for weld joint (WJ) using model, it is important to select model that properly reflects complex conditions of stress generated in the interface between base metal and heat-affected zone (HAZ). For 2 1/4Cr–1Mo steel, we examined what type scalar appropriate around HAZ accurately predicting rupture time, framework time exhaustion rule, which evaluates as function stress...
