The inverse tsunami problem of an island
(1989)
To date there exists no deep water record of a major tsunami from a benthic pressure gauge. Such deep water records and their spectra are desirable as a means of characterizing the tsunami source. The closest thing to such ...
Computer simulation studies of radiation damage to biomolecules : gamma-ray irradiation of polyuridylic acid
(1994)
The objective o f this dissertation is to investigate the physical and chemical mechanisms involved when ionizing radiation interacts with biological m olecules in aqueous solution. Polyuridylic acid has been selected as ...
Kinetic modeling of the Fischer-Tropsch synthesis
(1990)
The objective of this work was to develop a kinetic model to describe the conversions and selectivity typical of iron based Fischer-Tropsch catalysts, and to apply the model in simulations of typical laboratory reactors. ...
Intelligent tutoring system design for engineering science courses
(1991)
Recent changes in computer technology have made the development of an intelligent tutoring system (ITS) a much more attractive proposition. Reviewing the current educational engineering software, two major deficiencies ...
Gas chromatography/mass spectrometry detection of polycyclic aromatic hydrocarbon metabolites in fish and its applications in environmental studies
(1994)
The Great Lakes are surrounded by heavily industrialized regions. High frequency of hepatocellular neoplasm in fish has been found. This study was undertaken to assess the environmental contamination by analyzing polycyclic ...
Selective alkylation of toluene with methanol over pentasil-type catalysts
(1993)
Para xylene is a valuable aromatic compound, because of the demand for oxidation to form tetraphthalic acid, a feed stock for polyester resin and fibers. A relatively high cost is associated with obtaining it in 99+% purity. ...
Why are calls of convertible preferred stock delayed? : tests of the passive investor hypothesis and the call faliure hypothesis
(1993)
Ingersoll (1977a) and Brennan and Schwartz (1977) show that, in perfect markets, managers maximize common stockholders' wealth by calling a convertible security as soon as its conversion value exceeds its call price. ...
Thermohydrodynamic analysis of product-lubricated hydrostatic bearings in turbulent regime
(1992)
A bulk-flow thermohydrodynamic (THD) analysis is developed for accurate predictions of the static and dynamic performance characteristics of turbulent flow product-lubricated hydrostatic journal bearings (HJBs). Pointwise ...
Attitudes of small-scale fishermen in Pangandaran, Indonesia toward selected governmental programs, the occupation of fishing, and risk
(1990)
This study analyzed selected problems of small-scale fishermen in Indonesia, related to governmental assistance, fishing as an occupation, and their willingness to take risk associated with fishing practices. The population ...
