Revision of the genera Amblyomma Koch, 1844 and Haemalastor Koch, 1844, in North and Central America and description of a new genus (Acarina: Ixodidae)
(1966)
A taxonomic study of the genus Amblyomma (Acarina: Ixodidae) in North and Central America has been conducted, in which the genus, as currently interpreted, is divided into three genera, Amblyomma Koch, 1844, Haemalastor ...
Morphological and physiological studies of the foliar embryos of Kalanchoe pinnata Pers
(1966)
One of the outstanding features of Kalanchoe pinnata Pers. is the formation of foliar embryos in the sinuses of the leaves. The embryos will erupt, under the proper conditions, forming a plant with typical roots, stems, ...
Lysogeny and virulence in Bacillus anthracis cultures
(1966)
The purpose of this study was to determine if the virulence of two Bacillus anthracis cultures was directly associated with lysogeny. Two known virulent lysogenic cultures, designated AM1 and AM2, were selected for this ...
Effect of treating soils of different clay mineralogy with solutions varying in electrolyte concentration and sodium adsorption ratio
(1966)
The relative ionic concentration and the total ionic concentration of irrigation waters are two main factors affecting soils. The present study investigated variations in relative ionic concentration and total ionic ...
The effect of lateral wall deformations on pressures induced by a granular cohesionless material in a shallow bin
(1966)
This work presents the results of a series of tests designed to determine the validity of the coulomb wedge theory for predicting lateral pressures in a shallow grain storage bin and to determine the relationship between ...
Stiffness matrix solution for shells of revolution possessing variable thickness heat protection
(1966)
A composite laminated torispherical shell was idealized as a network of curved beams. A stiffness matrix method was developed in torispherical coordinates which are amenable to the current family of manned spacecraft. The ...
