We have investigated the growth and reactivity of chromium layers deposited onto a thin alumina film at room temperature and at 570 K. The interaction between Cr and the Al2O3/NiAl(1 1 0) surface leads to partial oxidation to Cr2þ and Cr3þ species. Complete oxidation to Cr3þ was achieved using moderate O2 doses at room temperature in vacuum. Cr has also been deposited in an O2 background pressu...
A threonine-producing strain of Serratia marcescens Sr41 was constructed according to the following process. Thr- strain E-60 was derived from strain HNr59 having constitutive levels of threonine-sensitive aspartokinase and homoserine dehydrogenase. Thr+ transductant T-570 was constructed from strain E-60 and phage grown on strain HNr21 having feedback-resistant threonine-sensitive aspartokinas...
We sought to determine if serum total iron-binding capacity (TIBC) is equivalent to serum transferrin (TRF) so that a low-cost colorimetric chemical assay for unsaturated iron-binding capacity (UIBC) could be substituted for a high-cost immunologic assay for TRF. Our study design included independent and blinded measurements of UIBC, serum iron, and TRF concentrations in human serum samples. Da...
