Synchronous rectifiers (SRs) are important for high-output-current LLC converters in order to reduce the secondary conduction loss. Conventional SR driving schemes are not suitable for high-frequency LLC converters: the analog driving schemes will lose ...

Global compilations indicate that the geochemistry of arc magmatism is sensitive to Moho depth. Magmatic products are prevalent throughout the history of Cordilleran orogenesis and can be employed to constrain the timing of changes in crustal thickness ...

A 3-week tour of the Far East was coordinated by Dr. Ronald DeWald, senior travelling fellow appointed by the Scoliosis Research Society. Three junior fellows appointed by the Education Committee of the Scoliosis Research Society accompanied him. The purpose of this fellowship was to develop a comaraderie and exchange ideas, thoughts, and experiences ...

Influence of seawater Sr content on coral Sr/Ca and Sr thermometry
Coral Reefs, 2005The Ca content of a Porites coral from Xisha, South China Sea is quite uniform along its 18-year growth axis. A comparison with previously published data shows that the Ca content of corals from different sites varies by only 0.4%. This is much smaller than the variation of Ca in seawater (2.2%), indicating that Ca variations in seawater do not ...

New and generalised previous isotope composition (??????Sr/??????Sr) data of apatites from various Proterozoic magmatic alkaline and subalkaline rocks, carbonatites, gabbroids, pyroxenites and fenites of the Ukrainian Shield are given. Frequently the rare metal, apatite and ilmenite deposits are related to these rocks.
