Solutions of second-order forced systems possessing hysteresis
(1969)
This work develops a method for the solution of second-order forced systems possessing hysteresis over an initial time interval, t₀[less than or equal to]t[less than or equal to]t₀+T. The specific problem that is treated ...
A variable-reduced-mass model for quasilinear molecules with application to HSiBr
(1969)
A Hamiltonian for large amplitude bending and K-type rotation of triatomic molecules has been derived. The complete dependence of the kinetic energy on the bending angle is included. The Hamiltonian contains two terms in ...
On the location of zeros of bipolar polynomials
(1969)
In this dissertation we have considered triplets of polynomials with real coefficients and of the same degree whose coefficients are related in a certain algebraic manner. Properties of this algebraic relationship and its ...
Physical properties of some binuclear copper (II) complexes
(1969)
The copper(II) complexes of citric acid and N,N'-diglycylethyl-enediamine have been studied in aqueous solutions in the pH range 2 to 10 electron spin resonance, nuclear magnetic resonance, optical spectrophotometry, and ...
Differentiation in programs of study and supervised experiences in elementary school counselor preparation programs in the United States
(1969)
The three major objectives of the research were: 1. to ascertain the degree to which United States counselor education programs were differentiating their programs of study and supervised experiences for candidates for ...
Histopathology of the interrelations of Sphacelotheca reiliana (Kuhn) Clint. and Sorghum bicolor (L.) Moench
(1969)
Sphacelotheca reiliana, the causal organism of sorghum head smut, develops only in actively growing host meristematic tissue. Three types of mycelium are found in a developing sorus. A thin parasitizing mycelium was ...
A study of industrial arts activities for educable mentally retarded junior high school youth with implications for guidelines in special industrial arts activities
(1969)
The purpose of the research was to compare present practices of industrial arts teachers in programs for educable mentally retarded (EMR) youth with those of special education teachers who teach some phase of industrial ...
A taxonomic and ecological study of selected benthonic gammarid crustaceans from the northeastern Gulf of Mexico
(1969)
From May 1964 until May 1966 a fouling study was conducted off the coast of Panama City, Florida. In the course of this investigation samples of organisms were taken from floats exposed at various controlled depths for ...
Diffusion coefficients of some transition metal complexes
(1969)
The polarographic and chronopotentiometric techniques were used to determine the diffusion coefficients of some mono- and polynuclear complexes of transition metal ions using the Ilkovic and Sand equations with electrochemical ...
The preparation of some aminoalkylphosphonic acids and related compounds
(1969)
Six phosphonocarboxylate esters were prepared. The esters synthesized were: [line break] triethyl phosphonoacetate [line break] diisopropyl methyl phosphonoacetate [line break] triethyl 4-methyl-2-phosphonopentanoate [line ...
