An investigation of the effects of temperature and of zinc on
development of tobacco mosaic virus (TMV) in resistant and susceptible
varieties of tomatoes was conducted under greenhouse conditions.
The study included two experiments, one run during late winter and
early spring, and the other during late spring and summer,...
The exponential family of probability distributions is obtained
from σ-finite measures on the real line. We choose the parameter
space to be one-dimensional and the exponent to be linear. Relationships
between the measure, its spectrum, and the parameter space
are examined, moments of the exponential family are studied, and
the...
Studies involving freeze-dried methyl linolenate-gelatin foams indicate that the extent of lipid-protein interaction corresponds to the degree of autoxidation of the lipid fraction. It appears that approximately 11% of the malonaldehyde as defined by the 2-thiobarbituric acid test is firmly bound to the protein. The induction period of autoxidation is...
This dissertation describes a new radio-frequency power-amplifier circuit and mode of operation that exceeds the efficiency of the conventional class C amplifier in the low and medium h-f range. It will be found useful in applications where linearity between the input and output are not required, as in all applications...
In order to examine some possible tyrosyl interactions, poly-tyrosyl lysozyme and poly-O-methyltyrosyl lysozyme were prepared and their solubilities were compared. Both derivatives exhibited
similar pH dependent solubilities, showing a minimum solubility at
about pH 8. Their solubilities varied with temperature, having a
positive enthalpy of solution. The effect of a...
In situ salinity, turbidity and temperature were measured at discrete depths and water samples for radioanalysis were simultaneously collected in the Columbia River Estuary using a specially designed instrument package. Particulate radioactivity was concentrated by filtration and the dissolved radioactivity by evaporation or ferric oxide bulk precipitation. Radioanalysis was by...
