This work focuses primarily the development of methods for imaging microbial biofilms in opaque porous media using x-ray computed microtomography (CT). Two methods for evaluating biofilms in porous media are presented. The first focuses on the addition of silver-coated, hollow glass microspheres to a biofilm-containing micro-model. The silver-coated microspheres affix...
A significant barrier to the diffusion bonding of large (i.e. 600 mm) microchannel devices is the large capital investment required to setup production. This large capital investment extends from long heating and cooling cycles leading to poor production
capacities. Empirical studies in industry have shown that cooling rate is limited...

Interest in social-emotional and character development (SECD) programming has intensified in recent years. SECD-related programs often seek to enhance a variety of health-related outcomes by addressing multiple influences and embracing a comprehensive approach that includes youth, school personnel, families, and communities. Alongside a comprehensive approach arises the need for a...
Research regarding factors that promote high-quality implementation of school-based prevention programs has increased markedly over the past decade as it has become increasingly recognized that evidence-based programs are often not well implemented. Whole-school interventions may be particularly complex to implement because they are intended to involve all school personnel and...
Implementation fidelity (dosage, adherence, quality of delivery, responsiveness, program differentiation) is the degree to which a program was carried out to its original intent. The following three studies examined the implementation fidelity of a school-based health promotion social and character development (SACD) program. The, Positive Action (PA) program was a...
The purpose of this work was to explore the feasibility of using the GOTHIC thermal hydraulics software package to model a pressurized conduction cooldown event in the High Temperature Test Facility. To achieve that aim, a model of the facility was constructed in the GOTHIC software and a selection of...

Chemical microreactors offer opportunities for portable power generation, on-site
waste remediation and point-of-use chemical synthesis. Much of the existing
development of microreactor devices involves silicon-based microfabrication techniques.
It is recognized that new refractory materials are important to realizing high-temperature
microreactors. Requirements of these materials include high-temperature resistance,
chemical inertness and...
In the Pajaro Valley near Watsonville, California,
twospotted spider mite (Tetranychus urticae Koch)
populations were surveyed in 1983 and '84 to detect the
influence of immigrants from nursery plants or
surrounding vegetation on subsequent resistance
development to cyhexatin and formetanate in strawberry
fields. Susceptible mites (cyhexatin LC50 = 0.0039 %...
Membrane based heat pumps systems have attracted the attention of many research groups as a potentially more environmentally friendly alternative to vapor compression systems that are being used for space cooling in 90\% of the buildings in the United States. Several prototypes systems have been developed, with reported claims of...
