Linear and nonlinear analysis of shells of revolution with asymmetrical stiffness properties
(1969)
A method is described for the linear and nonlinear elastic analysis of shells of revolution, under arbitrary loading, with variable thickness properties in the circumferential direction as well as in the meridional direction. ...
The synthesis and infrared spectra of some group VA chalcogenides
(1969)
The preparation of compounds having the general formula R₃MX, where R is an alkyl group, M is P, As or Sb and X is O, S, Se or Te has been carried put previously. The fundamental stretching frequency, ν[subscript S](M=X), ...
Methods of determining inservice training needs of beginning county extension agents
(1969)
The purpose of the study was to determine relative effectiveness of alternative methods of determining inservice training needs of beginning county extension agents. Nationally, Cooperative Extension Services employ ...
A model (formula) for deriving a hazard index of rail-highway grade crossings
(1969)
The purpose of this research was to compile data for use as related information in the education of drivers and to derive a formula for computing a hazard index for rail-highway intersections. The data for the study were ...
Factors which determine stearic and oleic acid concentrations in animal fats
(1969)
Ruminant and swine triglycerides have higher concentrations of stearic acid and lower concentrations of oleic acid than do triglycerides of other animals such as rats and chickens. Two new theories are herein advanced to ...
The utilization of phosphonic esters in the Knoevenagel condensation
(1969)
A study has been made of the kinetics of the Knoevenagel condensation, wherein phosphonlc esters have been employed as the active methylene compounds. The relative reactivities of each of the active methylene compounds ...
Transverse effects in thin elastic shells
(1969)
A shell theory is introduced which uses linearly exact expressions for the transverse variation of the displacement components. These displacement variations, first formulated by Kozik, include separately the effects of ...
The effect of solution composition on unsaturated hydraulic conductivity of some Texas soils
(1969)
The effect of solution composition on unsaturated hydraulic conductivity of Houston Black clay, Beaumont clay, Katy fine sandy loam, Nacogdoches fine sandy loam and Troup sand was determined. Samples representing defined ...
Maximum-likelihood detection of uniform convolutional codes
(1969)
An algebraic decoding algorithm for the maximum-likelihood detection of uniform convolutional codes is developed. Coded signals are assumed transmitted over a coherent PSK channel which is corrupted by additive white ...
Relationships between planktonic, epiphytic, and epipelic diatom populations in selected ponds of Brazos County, Texas
(1969)
Three ponds located in Brazos County, Texas, were sampled regularly for a period of one year, from August 1964 through August 1965, in order to study diatom populations on a seasonal basis. Samples were collected from each ...
