Incorporation of line quantities in the continuum description for multiphase, multicomponent bodies
(1994)
In this thesis the continuum description for dynamic, multiphase, multicomponent systems with intersecting dividing surfaces, is developed. In this development, the contribution of line excess quantities (line mass density, ...
Synthesis and electrical discharge machining of advanced ceramics containing zirconium diboride
(1994)
The objectives of this research are to synthesize composites containing zirconium diboride under a variety of conditions, to fabricate ZrB$sb2$-based materials using wire-cutting and die-sinking electrical discharge machines, ...
Wettability of porous media by nuclear magnetic resonance relaxation methods
(1994)
Wettability is a major factor which influences the distribution of multiphase fluids in reservoir rocks. However, the conventional methods for determining wetting characteristics of reservoir rocks are difficult and ...
The effect of temperature and pressure on laboratory oxidized asphalt films with comparison to field aging
(1994)
Two aging models, the asphalt-aging model and the highway-pavement aging model, are developed to describe oxidative aging in asphalt. The first model is based on first principles accounting for carbonyl formation and ...
Selective formation of isobutane and isobutene from synthesis gas over zirconia catalysts
(1994)
Isosynthesis is a process to synthesize isobutane and isobutene from hydrogenation of carbon monoxide. Certain metal oxides such as Z r02 and T h02 are active isosynthesis catalysts. Previous work in the literature concludes ...
Metabolic engineering of Escherichia Coli central metabolism : physiological effects of phosphoenolpyruvate carboxylase and phosphoenolpyruvate carboxykinase overproduction
(1994)
An ultimate goal of metabolic engineering is to achieve the maximum product yield. Much effort to date has been made to remove bottlenecks in the terminal pathways. As a result, the rate-controlling steps have been shifted ...
Conversion of synthesis gas to isobutylene over precipitated zirconia based catalysts
(1994)
Recent amendments to the Clean Air Act have renewed interest in synthesizing isobutylene from coal derived synthesis gas for use in producing methyl tertiary-butyl ether. Previous work on isosynthesis was performed at ...
Mathematical descriptions of Spodoptera frugiperda insect cell culture kinetics and recombinant protein yields
(1994)
Optimal design and operation of bioreactors for insect cell culture is facilitated by functional relations providing quantitative information on metabolite consumption kinetics of the cells, as well as on the specific cell ...
Modeling, parametric sensitivity analysis, and parameter estimation for methanol synthesis in trickle bed reactors
(1994)
Three types of reactor models were developed for simulating the performance of trickle bed reactors for methanol synthesis. These reactor models incorporate plug flow and axial dispersion with: resistance to interparticle ...
The kinetic studies of enzymatic cellulose hydrolysis and catalytic ketone hydrogenation
(1994)
Biomass, lignoceflulose in particular, is a potentially inexhaustible feedstock to produce environmentally safe fuels. It first can be hydrolyzed to simple sugars, which air, further processed by fermentation. Another ...
