Prevention of biofouling on heat transfer surfaces of ocean thermal energy converters. Progress report, May 1, 1975--November 30, 1975

Description: The objectives of the program were to develop chemical processes utilizing a combination of certain fluorochemicals and tribulyltin based toxicants for treating the surfaces of metals which may be used to fabricate OTEC heat exchangers, and to demonstrate the effectiveness of these surface treatments as antibiofoulants. Aluminium alloy No. 3003-H14 and titanium were testd, neither of which proved satisfactory. (WDM)

Correlation of mechanical and metallurgical parameters with the acoustic emission during tensile deformation of several metals and alloys

Description: Acoustic emission was monitored during plastic deformation under dead-weight tensile loading of polycrystalline aluminum, brass, copper, and steel. The acoustic emission data, both threshold-type and frequency-analysis type, were correlated with yield strength, stored elastic energy, strain hardening parameters, loading histories, diffusion processes, slip band motion and mosaic cell size. Major results are presented under the headings discontinuous yielding (Portevin--Le Chatelier Effect), par… more

Compilation of TFTR materials data

Description: In order to document the key thermophysical property data used in the conceptual design of Tokamak Fusion Test Reactor (TFTR) systems and components, a series of data packages has been prepared. It is expected that data for additional materials will be added and the information already provided will be updated to provide a project-wide data base.

Experimental studies of zirconium/aluminum getter pumps

Description: Getters of the type to be utilized as tritium pumps in the foreline of the TFTR torus vacuum system, and presumably in those of the neutral beam injector arms, were evaluated using hydrogen and deuterium. The capacity and speed as rated by the manufacturer (SAES) are found to be conservative. In addition, the getters are shown to continue to pump hydrogen even in the presence of chemically active, impurity gases, provided the getter temperature is maintained at >300/sup 0/C. Since hydrogen pump… more

Behavioral outcomes of short-term nondirective play therapy with preschool deaf children

Description: This study was conducted to investigate change (as measured by positive growth changes in total personality adjustment, social maturity, and behavior patterns) in pre-school deaf children with behavioral problems who experienced short-term, nondirective play therapy. Change in behavior of these children was also investigated ten weeks after therapy.

Analysis of activities in production typewriting and development of a teaching model and standards

Description: The problem of this study is an analysis of activities in production typewriting, development of a teaching model, and establishment of production standards. The study has four main purposes which are: (1) to identify the time spent in keystroking, decision making, typing from longhand copy, erasing an original, typing and correcting one carbon copy, and proofreading; (2) to test the correlation between anxiety level and decision-making time, and IQ and decision-making time; (3) to analyze the … more

Kinetics and mechanism of substitution reactions of tungsten carbonyl complexes containing bidentate sulfur ligands

Description: Previous investigation of the kinetics and mechanism of the substitution reaction of bidentate substituted transition metal carbonyl complexes with Lewis bases (L') to yield the cis distributed bidentate substitution product, where M=Cr, Mo, or W and S-S = DTO (2,2,7,7-tetra-methyl-3, 6-dithiaoctane) or DTN (2,2,8,8-tetramethyl-3,7-dithianonane) have suggested that this reaction proceeds via a mechanism involving initial reversible dissociation of one end of the bidentate sulfur ligand followe… more

Characterizations of properties of spaces of finitely additive set functions in terms of mappings and integrals

Description: Settings and notions are as in previous abstracts of W. D. L. Appling. This paper contains an investigation of the relationship between a class of non-linear functions defined on PAB and certain subspaces of PAB in particular Appling's linear C-sets, Solomon leader's finitely additive Lp spaces, and one of the projective limit spaces studied by Davis, Murray, and Weber.

The influence of Stoicism on the Jacobean drama

Description: The purpose of this dissertation is to identify the Stoic influences in the Jacobean drama. Although the Stoic figure and references to Stoicism appear frequently in this drama, there has never been a comprehensive study of the Stoic element in the drama of this period. This study will fill this scholastic gap.
