Structure of a Carbonate/hydrate Mound

A one-kilometer-diameter carbonate/hydrate mound in Mississippi Canyon Block 118 has been chosen to be the site of a multi-sensor, multi-discipline sea-floor observatory. Several surveys have been carried out in preparation for installing the observatory. The resulting data set permits discussing the mound’s structure in some detail. Samples from the water column and intact hydrate outcrops sho...

Comparison of carbonate and uricase-carbonate methods for the determination of uric acid in serum.

A colorimetric carbonate procedure for the determination of uric acid has been modified to include incubation of serum with uricase to destroy uric acid. Residual nonurate chromogens are subtracted from total chromogens to obtain the concentration of “true” uric acid. Result obtained by the carbonate and the uricase-carbonate methods were in good agreement. The mean concentration of nonurate ch...

Synthesis and Molecular Structures of (E)-non-2-enoic Acid and (E)-dec-2-enoic Acid

The molecular structures of (E)-non-2-enoic acid (C9) and (E)-dec-2-enoic acid (C10) are reported. The title compounds were crystallized by slow evaporation of ethanolic solutions at −30 °C. C9 crystallizes in the monoclinic space group P21/c and C10 in the triclinic space group P-1, each with 4 molecules in the unit cell. The unit cell parameters for C9 are: a = 10.6473(4) Å, b = 5.2855(2) Å, ...
