However, confirmatory study of reaction mechanisms has been frustrated by the elevated temperatures required to date to apply Q&P heat treatment to commercial steel compositions.
Confirmatory study well evidences that the extraction performance of TMD is comparable to that of the traditional laboratory solid-phase extraction process, but the proposed TMD is more simple and convenient.
We describe a confirmatory study in 212 prostatic adenocarcinoma and 135 benign prostatic hypertrophy patients designed to determine whether previous findings showing a protective effect for UV exposure could be reproduced.
