Sonochemical Oxidation Of Cyanide Using Potassium Peroxydisulfate As An Oxidizing Agent, M. Cui, M. Jang, S. Lee, J. Khim

Research Publications (2011 to 2015)

In this study, the sonochemical oxidation of cyanide in the presence of peroxydisulfate (PDS) ions has been investigated. As a result of experiments, sulfate anion radicals (·SO 4 -) and hydroxide radicals (·OH) produced by PDS ions in acoustic cavitation could readily oxidize and even mineralize cyanide in an aqueous environment. When the frequency of ultrasound and PDS ions were applied at 450 kHz and 60mg·L -1, the efficiencies of mineralization for free cyanide (CN -) and thiocyanate (SCN -) were 99.3 and 99, respectively. The kinetics of total organic carbon (TOC) reduction for CN - and SCN - oxidation …

Research Publications (2011 to 2015)

This study was set to investigate antiproliferative potential of dentatin (a natural coumarin isolated from Clausena excavata Burm. F) against prostate cancer and to delineate the underlying mechanism of action. Treatment with dentatin dose-dependently inhibited cell growth of PC-3 and LNCaP prostate cancer cell lines, whereas it showed less cytotoxic effects on normal prostate epithelial cell line (RWPE-1). The inhibitory effect of dentatin on prostate cancer cell growth was due to induction of apoptosis as evidenced by Annexin V staining and cell shrinkage. We found that dentatin-mediated accumulation of reactive oxygen species (ROS) and downregulated expression levels of antiapoptotic molecules …

Chikungunya virus (CHIKV) and related arboviruses have been responsible for large epidemic outbreaks with serious economic and social impact. The immune mechanisms, which control viral multiplication and dissemination, are not yet known. Here, we studied the antibody response against the CHIKV surface antigens in infected patients. With plasma samples obtained during the early convalescent phase, we showed that the naturally-acquired IgG response is dominated by IgG3 antibodies specific mostly for a single linear epitope E2EP3. E2EP3 is located at the N-terminus of the E2 glycoprotein and prominently exposed on the viral envelope. E2EP3-specific antibodies are neutralizing and their removal from …

Research Publications (2011 to 2015)

Increased expression of the transient receptor potential vanilloid 1 (TRPV1) channels, following nerve injury, may facilitate the entry of QX-314 into nociceptive neurons in order to achieve effective and selective pain relief. In this study we hypothesized that the level of QX-314/capsaicin (QX-CAP)--induced blockade of nocifensive behavior could be used as an indirect in-vivo measurement of functional expression of TRPV1 channels. We used the QX-CAP combination to monitor the functional expression of TRPV1 in regenerated neurons after inferior alveolar nerve (IAN) transection in rats. We evaluated the effect of this combination on pain threshold at different time points after IAN …

Examination Of Annual Variation In The Adult Sex Ratio Of Pronghorn (Antilocapra Americana), Justin D. Hoffman, Hugh H. Genoways Jan 2012

Examination Of Annual Variation In The Adult Sex Ratio Of Pronghorn (Antilocapra Americana), Justin D. Hoffman, Hugh H. Genoways

University of Nebraska State Museum: Mammalogy Papers

The adult sex ratio (ASR) is an important component of a population’s demographics and can be used as an indicator of a population’s status. However, the causes of annual variation in ASRs are unknown for many species. Fluctuations in ASR can arise through demographic stochasticity and intense selective harvesting. In this study we investigate the long-term patterns of variation in the ASRs (bucks: 100 does) for four populations of pronghorn (Antilocapra americana) in western Nebraska. We used multiple variables in a model selection process to predict annual fluctuation of pronghorn ASRs. We found that the number of bucks: …

The Seed, Justin R. Evertson, Christina Hoyt, Karma Larsen, Kendall Weyers, Bob Henrickson

Nebraska Statewide Arboretum: Publications

When it comes to managing our planted landscapes, we humans seem to prefer working against Mother Nature. Where she would provide a diverse mix of flora and fauna, we prefer trying to carpet the ground with a monoculture of lawn and then sprinkle a few colorful (and often foreign) trees, shrubs and other plants here and there as accents. We like to think that we’re in control, that we’ve created some- thing static and beautiful, but in reality we are regularly doing battle against natural processes and in many ways against our own best interests. We’ve come to accept near-constant …


Promoting Trust In Trusts & Estates, Michael R. Siebecker, Lee-Ford Tritt Jan 2012

Promoting Trust In Trusts & Estates, Michael R. Siebecker, Lee-Ford Tritt

Sturm College of Law: Faculty Scholarship

What nexus exists between the philosophy of trust and the law of trusts & estates (“T&E”)? This article suggests eschewing stilted economic theory in favor of a more robust understanding of the basic philosophical concept of trust to uncover the proper path that evolving T&E law should follow. In particular, the article advocates embracing the concept of “encapsulated trust” to ascertain the shape that fiduciary relationships should take in the realm of T&E doctrine. In simple terms, encapsulated trust represents a rational expectation that those in whom we place our trust will take our interests into account (or “encapsulate” our …

Economic Impact Of Stable Flies (Diptera: Muscidae) On Dairy And Beef Cattle Production, David B. Taylor, Roger D. Moon, Darrell R. Mark

Department of Agricultural Economics: Faculty Publications

Stable flies, Stomoxys calcitrans (L.), are among the most damaging arthropod pests of cattle worldwide. The last estimate of their economic impact on United States cattle production was published 20 yr ago and placed losses at $608 million. Subsequently, several studies of effects of stable flies on beef cattle weight gain and feed efficiency have been published, and stable flies have become increasingly recognized as pests of cattle on pasture and range. We analyzed published studies and developed yield-loss functions to relate stable fly infestation levels to cattle productivity, and then estimated the economic impact of stable flies on cattle …
