The bioavailability of vitamin B-6 from four selected
foods was investigated in five men, aged 22 to 25 years,
who were receiving a pyridoxine supplement. The subjects
received a constant diet containing 1.34 mg of vitamin B-6
throughout this five-week study, except on Saturdays and
Sundays when they ate their...
Environmental quality and the spatial distribution of economic activities affect each other in many ways. The primary purpose of this dissertation is to contribute to understanding the complex interrelationship and its policy implications. This dissertation consists of three essays.
The first essay examines the roles that locational amenities and increasing...
This study is intended to investigate and propose a systematic method for uncertainty quantification for the computer code validation application. Uncertainty quantification has gained more and more attentions in recent years. U.S. Nuclear Regulatory Commission (NRC) requires the use of realistic best estimate (BE) computer code to follow the rigorous...
Water scarcity and extreme weather present substantial risks for agricultural production on the U.S. West Coast. Farmers adapt to water supply uncertainties and climate risks by changing water application rates, adjusting irrigated acres, adopting more efficient irrigation technology, and altering crop mix. Many policy options are available to attain sustainable...
The publicly subsidized Federal Crop Insurance Program has expanded rapidly in recent decades in the United States. With the reform in the 2014 Farm Bill, the Federal Crop Insurance Program has become the most important component of U.S. farm policies. The primary goal of the program is to provide risk...
The application of two-phase magnetohydrodynamic(MHD) in liquid metal cooled nuclear reactors presents opportunities to simplify the power generation system by eliminating moving components like a turbine for enhanced safety. The proposed system in this thesis consists of two loops with immiscible working fluids. The compressed gas expands in the two-phase...
This thesis examines two techniques for measuring two-phase flow parameters in an air/water system using intrusive conductivity probes. Specifically, the theoretical derivation for measuring void fraction and interfacial area using a two-sensor needle-type probe is derived, and a statistical analysis of the accuracy using the two-sensor probe for measuring interfacial...
A phase distribution parameter has been added to the one-dimensional two-phase horizontal flow conservation equations. The phase distribution parameter was incorporated into the conservation equations in an attempt to add stability and remove correlation switching by incorporating gravity. Determination of the phase distribution parameter requires an average void fraction profile...
NuScale Power has designed a small modular reactor using natural circulation cooling dependent systems for both steady-state and transient operations. The NuScale Integral Test System (NIST-1) facility was built to supply test data to NuScale Power to verify and validate computer codes for the NuScale Power Mod- ule (NPM) with...
A mechanistic based critical heat flux (CHF) correlation has been developed derived from a mass, momentum, and energy balance at a nucleation site for water. The trigger mechanism for the CHF condition is postulated to be related to the maximum boiling frequency on a heated surface. It is observed that...
