Selective Determination Of Methylmercury By Flow-Injection Fast-Scan Voltammetry, Rebecca Lai, Eva Huang, Feimeng Zhou, David O. Wipf

Rebecca Lai Publications

A simple flow-injection system, suitable for solution flow rates at microliters-per-minute, has been combined with fast-scan voltammetry for selective determination of methylmercury. A thin Hg film was formed at a Pt microelectrode prior to the measurement. Detection of methylmercury is carried out by measuring the oxidation of methylmercury radicals that have been generated at the Hg microelectrode. At slow scan rates, the electrogenerated methylmercury radicals undergo a follow-up dimerization reaction to form dimethyldimercury (E_rC_i² mechanism). At fast scan rates, it was found that methylmercury radicals can be quantitatively reoxidized (reversible electron-transfer). Optimization of the experimental conditions …

Magnetic And Magneto-Optic Study Of A Layered Co/Pt - Dysprosium-Iron-Garnet System, J.M. Meldrim, Roger D. Kirby, M.J. Devries, John A. Woollam, David J. Sellmyer

Department of Physics and Astronomy: Faculty Publications

Abstract-We have studied the effects of placing Co/Pt multilayers on dysprosium-iron-garnet doped with bismuth and aluminum. The garnet was deposited by RF-magnetron sputtering and crystallized by rapid thermal annealing. The Co/Pt multilayers were then deposited by DC-magnetron sputtering. The garnet thickness was held constant at lOOO Å while the ColPt multilayer had the form of [3 Å Co/9 Å Pt]_n with n ranging from 1 to 16. Coercivities of the samples ranged from about 300 to 2000 Oe. Kerr rotations were as high as 1.8° and ellipticities up to 2° depending upon the wavelength of light and the number …

Analysis Of Social Behavior In Individuals With Social Phobia And Nonanxious Participants Using A Psychobiological Model, Kenneth S. Walters, Debra A. Hope

Department of Psychology: Faculty Publications

This study sought to test hypotheses derived from Trower and Gilbert’s (1989) psychobiological/ethological model of social anxiety. This model purports that social anxiety should be characterized by less social cooperation and dominance and greater submission and escape/avoidance. Individuals with social phobia and nonanxious participants completed a structured social interaction. Behavioral measures related to cooperativeness, dominance, submissiveness, and escape/avoidance were coded by independent observers. Those with social phobia exhibited fewer behaviors of social cooperativeness and dominance than did nonanxious participants. The groups did not differ with regard to submissive and escape/avoidance behaviors. Two dominance behaviors correlated with a self-report measure of …

Thermal Stability And Nanostructure Of Cocrpt Longitudinal Recording Media, Mingjun Yu, Mary F. Doerner, David J. Sellmyer

David Sellmyer Publications

We report a systematic study of activation volumes and their correlation with physical grain sizes and thermal stability in CoCrPt media fabricated by magnetron sputtering. Different underlayers and CoCrPt layer thicknesses were used to provide a range of lateral grain sizes, M_Iδ (product of remanence M_I and film thickness δ) values, and remanence coercivities. Two methods, namely the field-sweep-rate dependence of coercivity and measurements of magnetic viscosity and irreversible susceptibility, were used to determine the activation volumes and the results obtained from the two methods are in reasonable agreement. For CoCrPt layer thickness from 10 nm to …

Morphological Development Of 2 Warm-Season Grasses In The Nebraska Sandhills, J. R. Hendrickson, Lowell E. Moser, K. J. Moore, Steven S. Waller

Department of Agronomy and Horticulture: Faculty Publications

Morphological development of grasses has numerous implications to rangeland management including the timing and amount of herbivory. The objective of this study was to quantify the developmental morphology of prairie sandreed [Calamovilfa longifolia (Hook.) Scrihn.] and sand bluestem [Andropogon gerardii var. paucipilus (Nash) Fem.] tiller populations. Tier populations of these 2 grasses were studied for 2 years in the Nebraska Sandhills. Plant development was evaluated using a growth staging system which quantifies the development of tiller populations. A morphological growth index for each species was calculated from either the weighted average of tiller numbers reported as mean stage …

System And Method For Performing Optical Code Division Multiple Access Communication Using Bipolar Codes, James F. Young, Benhaam Aazhnag, Lim Nguyen

Department of Electrical and Computer Engineering: Faculty Publications

An optical encoding and decoding system which performs code-division multiple access (CDMA) communication in the incoherent, or direct detection, optical domain using bipolar +1/-1 codes. The present invention uses code modu lation and detection principles that permit all-optical imple mentation of the bipolar. +1/-1. code and correlation detec tion that have been developed for the radio frequency (RF) systems. This is possible in spite of the non-negative, or unipolar, +1/0, nature of the incoherent optical system that only detects and processes the signal intensity. The unipolar optical system of the present invention is equivalent to the bipolar RF system in …

Australia’S National Drought Policy Continues To Evolve, David H. White

Drought Network News (1994–2001)

Australia is an arid continent with a high variability in its annual rainfall. Given the frequency and severity of droughts and the consequent high financial and social costs to the nation and to individuals, and the associated potential for further degradation of the land, a national policy on drought was clearly needed.

Australia’s National Drought Policy (NDP) was ratified by the state and Commonwealth (federal) governments in 1992 (White, 1993; White et al., 1993; White and O’Meagher, 1995). Its aims are to:

• encourage primary producers and other sections of rural Australia to adopt self-reliant approaches to managing for climatic …

From The Director: June 1998, Donald A. Wilhite

Drought Network News (1994–2001)

The 1997–98 El Niño event has certainly raised the public’s level of awareness of the impact of climate on society. Although the concern in the United States has focused more on mitigating the potential effects of floods, not all regions of the country are dealing with water surplus situations. An emerging drought in Montana and parts of some surrounding states has caught the attention of scientists and policy makers in recent months. Worldwide, droughts in Central America, Mexico, Brazil, Hawaii, some Pacific island nations, Indonesia, Australia, southern Africa, and elsewhere have attracted the attention of scientists, policy makers, and the …

Expression Of Human Lactoferrin Cdna Confers Resistance To Ralstonia Solanacearum In Transgenic Tobacco Plants, Zhanyuan Zhang, Dermot P. Coyne, Anne K. Vidaver, Amitava Mitra

Department of Plant Pathology: Faculty Publications

A construct containing a human lactoferrin cDNA was used to transform tobacco (Nicotiana tabacum) using an Agrobacterium-mediated DNA-transfer system to express this human protein in transgenic plants. Transformants were analyzed by Southern, Northern, and Western blots to determine integration of the cDNA into the plant genome and lactoferrin gene expression levels. Most transgenic plants demonstrated significant delays of bacterial wilt symptoms when inoculated with the bacterial pathogen Ralstonia solanacearum. Quantification of the expressed lactoferrin protein by enzyme-linked immunosorbent assay in transgenic plants indicated a significant positive relationship between lactoferrin gene expression levels and levels of disease …

Uptake And Bioconcentration Of Atrazine By Selected Freshwater Algae, Jixin Tang, Kyle D. Hoagland, Blair Siegfried

Department of Entomology: Faculty Publications

Atrazine bioconcentration and uptake were determined for eight freshwater green algae and diatoms. Atrazine uptake was extremely rapid in all species examined, with nearly 90% of total uptake occurring within the first hour of exposure. Within each division, different species had different bioconcentration capacities, although the accumulation of atrazine was consistently higher in green algae (5.43–12.73 ng/mg) than in diatoms (0.33–1.69 ng/mg). Atrazine concentrations in the algal cells were much higher than in the medium, although the total amount of atrazine taken up by algae was small relative to the total atrazine in solution (1–3%). The ability of algal cells …

Thickness Dependence Of Interfacial Magneto-Optic Effects, Xiang Gao, Michael J. Devries, Daniel W. Thompson, John A. Woollam

Department of Electrical and Computer Engineering: Faculty Publications

Spectroscopic ellipsometry and magneto-optic Kerr effects are measured on Pt/Co multilayers with a series of Co layer thicknesses from 0.08 to 1 nm. An electromagnetic theory of multilayered structures allows regression analysis fits between acquired data and parameter dependent model analysis. Recently, we determined the single layer Co magneto-optic Voigt parameter and found that it depends on Co layer thickness. In the present work, we report an in-depth study of interfacial magneto-optic effects for a large number of Pt/Co multilayer samples. Kerr rotation and ellipticity were measured over the spectral range from 200 to 1700 nm. Voigt parameters of the …

On Editing Hemingway Badly Or Not At All: Cautionary Reflections, Susan F. Beegel

Documentary Editing: Journal of the Association for Documentary Editing (1979–2011)

The archivally correct cardboard boxes of the Hemingway Collection pulse with energy. Hemingway's estate included at his death nearly twenty thousand pages of holograph, typescript, carbon, and proof. Those pages make up more than eight hundred manuscripts of published and unpublished work, and vividly show the composition process of twentieth-century American literature's most influential prose stylist. They represent as well one of the last and finest opportunities to study the composition process itself, now that the delete key has arrived to send all false starts, alternative endings, errors, and omissions into the ether, and to cloak the writer's additions and …

United States Patent: Silicalite Membrane And Method For The Selective Recovery And Concentration Of Acetone And Butanol From Model Abe Solutions And Fermentation Broth, Michael M. Meagher, Nasibuddin Qureshi, Robert W. Hutkins

Department of Food Science and Technology: Faculty Publications

Silicalite. silicalite filled polymer membrane. and process for the selective adsorption of acetone and butanol from aqueous solutions thereof. The silicalite. silicalite filled polymer membrane. and process are particularly suited to the removal of acetone and butanol from Closfridium acetobutylicum fermentation media in that the membrane is not fouled by the fermentation media and may be used without removing the cells from the fermentation media. The silicalite and silicalite filled polymer membrane show excellent selectivity to the adsorption of acetone and butanol relative to the ethanol, acetic acid, and butyric acid components of the fermentation media.

“Other Teens Drink, But Not My Kid”: Does Parental Awareness Of Adolescent Alcohol Use Protect Adolescents From Risky Consequences?, Karen Bogenschneider, Ming-Yeh Wu, Marcela Raffaelli, Jenner C. Tsay

Department of Psychology: Faculty Publications

This study included 199 White mother-adolescent dyads and 144 White father-adolescent dyads. All adolescents reported regular alcohol use, yet less than one third of parents were aware of their adolescents’ drinking. Parental awareness of adolescent alcohol use served to protect adolescents by moderating the relation of parents’ responsiveness to episodes of drinking and driving. Aware parents were more likely than unaware parents to believe their adolescents’ close friends drank alcohol. Aware mothers worried more about their adolescents’ risk behaviors and discussed them more frequently with their adolescents. Aware fathers held values less disapproving of adolescent alcohol use and were less …

Polymerase Chain Reaction Detection And Phylogenetic Characterization Of An Agent Associated With Yellow Vine Disease Of Cucurbits, Francisco J. Avila, Benny D. Bruton, Jacqueline Fletcher, J. L. Sherwood, Sam D. Pair, Ulrich Melcher

Department of Plant Pathology: Faculty Publications

Diagnosis of yellow vine disease (YVD) in cucurbits, an important disease in the south-central United States, relies on external symptom appearance, phloem discoloration, and the presence of bacterium-like organisms (BLOs) in phloem. Polymerase chain reaction (PCR) amplification of BLO nucleotide sequences was explored as a means to improve diagnostic techniques. PCR, using a primer pair based on sequences of the citrus-greening BLO, amplified a 0.15-kilobase (kb) fragment from the DNA of symptomatic plants, but not from that of asymptomatic plants. Its nucleotide sequence suggested that the DNA amplified was of prokaryotic origin. A primer pair, designed to amplify nonspecific prokaryotic …

Gothic Pillars And Blue Notes: Art As A Reflection Of The Conflict Of Religions, Part Ii, Quentin Faulkner

Glenn Korff School of Music: Faculty Publications

The existence of an intense and vital artistic activity is the most unmistakable indicator of the new religion, but it is not the only one. Three of the most commonly identified manifestations of religion are cult (public worship), myth (salvation history, doctrine), and ethics (right behavior, morals). Secular culture exhibits each of these aspects of religion.

Cult is in some measure synonymous with public worship. (The modern English- language use of the term "cult" is a distortion that wholly obscures its original meaning.) The difference between the two is one of degree rather than kind. Cult in its fullest sense …
