Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...
Previous investigations of the biosynthesis of sterols by the
arterial wall have shown that the intact aorta is capable of low level
incorporation of labeled precursor into a sterol digitonide. The biosynthesis
of sterols and related lipids by a cell-free preparation of
bovine aorta was investigated in the present study....
Attempts to synthesize diboron tetrafluoride by the reduction of
boron trifluoride with alkali metal solutions in 1, 2-dimethoxyethane
proved to be unsuccessful. No diboron tetrahalide was found when
boron trifluoride, antimony trifluoride, or boron trichloride was
reacted with tetra-(dimethylamino)-diboron; although there appeared
to be some exchange between chloride and amine...
Ultraviolet spectroscopic methods for the determination
of dissociation constants can only be applied to
those compounds having protonatable sites conjugated with
or inherent in a chromophoric group of the compound.
The determination of the dissociation constants of
organic nitrogeneous bases by ultraviolet spectroscopic
methods was found to be only reliable...
