Phospholipids and cerebrosides of the normal chick sciatic
nerve were extracted by Folch procedures and separated with silica
gel thin-layer chromatography using various chloroform-methanol
solvents. The subsequent chemical assays were expressed as a function
of the developmental stages of the chick from 15 days of incubation
to 7 days after...
An instrument was developed which performs analysis of the
oxygen content of air by means of a commercial polarographic oxygen
electrode. The oxygen analyzer is part of a portable instrument
which converts the current from the oxygen electrode into a pulse
whose width is proportional to the oxygen concentration. This...
Hydrated cobalt(II) and nickel(II) trifluoromethanesulfonates have
been prepared by a previously reported procedure, and have been
characterized for the first time as [ Co(H₂O)₆] (CF₃SO₃)₂H₂O and [Ni(H₂O)₆] (CF₃SO₃)₂. These formulations are based on analyses,
near-infrared spectra, and on measurements of the ligand field
electronic spectra and the magnetic susceptibilities. The...
