The vitamin B₁₂ concentrations in both the water and sediments
of Klamath Lake were found to vary significantly during a
one-year period. The patterns of B₁₂ distribution were remarkably
similar among the three main sites. In all cases there was an extremely
sharp gradation in concentration in relation to depth...

The dielectric relaxation of V₂ 0₅ was investigated using the method of Davidson and Cole. By means of an Argand diagram, deviation from an exact Debye dielectric was established. This was done with the parameter β. For a Debye dielectric β= 1. The largest value of β for V₂O₅ was...
This investigation consisted of two parts: A. stability, B.
bioavailability of vitamin B₆ in wheat. Three variables; whole wheat
flour (WHW), white flour (W) and W enriched with vitamin B₆ (WB₆)
were tested.
Stability of vitamin B₆ during bread making and storage of
bread and flour was determined. Bread was...
Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow
trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to
Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy
confirmed the microsomal...
The purposes of the research presented in this thesis were: (1)
to determine the precision with which it is possible to measure
changes in vitamin B6 compounds in the blood and urine following
oral doses of levels of vitamin B6 (as pyridoxine) which are in the
range of the normal...
