For the in situ reductive immobilization of U to be an acceptable strategy for the removal of that element from groundwater, the long-term stability of U(IV) must be determined. Rates of biotransformation of Fe species influence the mineralogy of the resulting products (Fredrickson et al., 2003; Senko et al., 2005), and we hypothesize that the rate of U(VI) reduction influences the mineralogy of resultant U(IV) precipitates. We hypothesize that slower rates of U(VI) reduction will yield U(IV) phases that are more resistant to reoxidation, and will therefore be more stable upon cessation of electron donor addition. U(IV) phases formed by relatively slow reduction may be more crystalline or larger in comparison to their relatively rapidly-formed counterparts (Figure 1), thus limiting the reactivity of slowly-formed U(IV) phases toward various oxidants. The physical location of U(IV) precipitates relative to bacterial cells may also limit the reactivity of biogenic U(IV) phases. In this situation, we expect that precipitation of U(IV) within the bacterial cell may protect U(IV) from reoxidation by limiting physical contact between U(IV) and oxidants (Figure 1). We assessed the effect of U(VI) reduction rate on the subsequent reoxidation of biogenic U(IV) and are currently conducting column scale studies to determine …

A flier advertising a meeting of the Immigrant Labor Rights Tour. It includes the logo of the group and information about the event. The sponsors are listed beneath the summary.

A document that collects images from events hosted by the UNT Multicultural Center.

A flier for the UNT Safer Spring Break Week programs. There are five events throughout the week and students can enter a drawing for a prize if they attend three programs. At the bottom are several logos for the organizations around the UNT campus.

This poster discusses how a complex view of coping can facilitate understanding of how patients adapt to HIV and help guide researchers in the development of interventions that fit the specific disease course.

This poster examines depression's relationship to the combination of pessimism, sexual trauma, living arrangements, and interpersonal dependency, as well as personal demographics in college students.

This poster explores the relationship of depression, stress, and sleep quality with self-efficacy in Complementary and Alternative Medicines users living with HIV/AIDS.

This poster examines how people living with HIV/AIDS use spiritual beliefs to interpret the meaning of or perhaps appraise illness in such a way that it has a strong positive association with higher levels of psychological quality of life.

This poster examines how therapeutic interventions to identify and address symptoms of trauma, as well as to promote forgiveness of unpleasant experiences, would be associated with lower rates of depression in people living with HIV/AIDS.

This poster examines relationships between health protective sexual communication, depression, and STD attitudes.

This poster discusses preparing, creating, and managing a large dataset of MARC 21 records. The MARC Content Designation Utilization (MCDU) Project is examining catalogers' utilization of available MARC 21 content designation (e.g., fields/subfields). A critical component of this project is the development of methods, procedures, and software tools for reliable and valid analyses of the complete WorldCat database of more than 56 million MARC 21 records.

Poster presented at the 2006 ALISE Conference (Doctoral Poster session). The poster was one of the five award-winning poster presentations for the best doctoral dissertation proposal.

Over the past two decades, numerous studies have produced high quality information on the rates at which bacteria can reduce metal oxides. The prototypical study--such as the one depicted to the right--focuses on only a few of the myriad variables affecting the rate. This approach allows for effective dissection of the mechanisms underlying DMRB activity, but, it also produces disjoint information that must be synthesized if we hope to predict the behavior of bacteria at the systems level.

Poster with the caption "Cowboys of Color Rodeo." Four men are standing in the dirt of an arena. Behind them, a fifth man stands between two horses. A boy and a girl are each sitting atop a horse.

Poster with various pictures of Cleo Hearn including one of him in a rodeo and a family photograph. There is a stripe in the middle of the poster that says "Congratulations" with Texas and Ford logos. At the bottom is a quotation attributed to Hearn that says, "I believe...to be happy in life you need three things: something to love, something to do and something to look forward to."
