Ecological and phenological characteristics of perennial broomweed
(1969)
Phenological and ecological characteristics of perennial broom-weed (Xanthocephalum sarothrae (Pursh) Shinners and X. microcephalum (DC.) Shinners), species toxic to livestock, were investigated at six locations in western ...
An analysis of the radiation characteristics of asymmetrically-driven thin linear antennas
(1969)
A study is made of the radiation characteristics of the thin, linear antenna of arbitrary length and driving-point location. A compact algebraic expression for the radiation field of this antenna is found, a special case ...
Preparation of some diaminoalkylphosphonic acids
(1965)
Four diaminoalkylphosphonic acids (I) and their N-Benzoyl [see Proquest PDF for equation (I)] derivatives were synthesized, utilizing a modified Curtius reaction. The successful synthesis of this series of compounds provided ...
Ultrastructural study of control and acute, whole body gamma-irradiated medulla oblongata tissue
(1969)
Investigations of the ultrastructure in the medulla oblongata of non-irradiated and acute, whole body, gamma-irradiated rats were carried out. There were five groups of animals, one control and four irradiated. The irradiated ...
Structure-solubility relationships for some 2-substituted anthraquinones and estimation of heats of fusion from solubility data
(1969)
The mole fraction solubilities of eleven 2-substituted anthraquinones in chloroform (X₁) and in carbon tetrachloride (X₂) have been determined and are in the range of 10⁻² to 10⁻⁶, except that of 2-t-C₄H₉-anthraquinone ...
The potential of irradiation and induced polyploidy for improving St. Augustinegrass Stenotaphrum secundatum (Walt.) Kuntze
(1966)
St. Augustinegrass, Stenotaphrum secundatum is a warm-season perennial species of the tribe Paniceae. The species is classified as a sod-forming grass and is characterized by its stoloniferous growth habit and absence of ...
