Antibacterial Activity Of Amchur (Dried Pulp Of Unripe Mangifera Indica) Extracts On Some Indigenous Oral Microbiota Causing Dental Caries, Charu Gupta, Amar P. Garg, Ramesh C. Uniyal

Ethnobotanical Leaflets

The antibacterial activity of amchur (dried pulp of unripe Mangifera indica) extract (50% ethanol) was tested against ten bacterial strains causing dental plaque by agar well diffusion method. The crude extract showed a broad spectrum of antibacterial activity inhibiting both the groups of Gram-positive & Gram-negative bacteria. The extract was most effective against Bacillus sp., followed by Staphylococcus mutans and Pseudomonas sp., whereas Halobacterium sp. was found to be the most resistant. Chlorhexidine (present in mouthwashes to prevent infection of dental caries) was used as a positive control. Natural extract of amchur was found to be more effective as compared …

Improved Red-Emitting Firefly Luciferase Mutant For Biotechnical Applications, Audrey L. Davis

Chemistry Honors Papers

Luciferase from the North American firefly Photinus Pyralis catalyzes a highly efficient bioluminescent reaction that produces yellow-green light (557 nm at pH 7.8). This bioluminescence system has been adapted for a variety of applications including gene reporter assays, detection of bacteria and toxins, whole-cell biosensor measurements, and in vivo imaging. A luciferase variant with a red-shifted bioluminescence spectra and high specific activity, two qualities that are challenging to achieve simultaneously, would be especially useful when paired with a green-emitting enzyme in a dual-color reporter assay, or used alone for improved imaging in living animals.

Our lab previously reported a red-emitting …

The Role Of Interferon Gamma In The Regulation Of Il-18 Binding Protein And The Development Of Autoimmune Arthritis In A Genetically Non-Susceptible Mouse Strain, Timothy Daniel Kayes

Theses and Dissertations (ETD)

The etiology of the autoimmune disease rheumatoid arthritis (RA) is unknown, but the role of cytokines, including IFN-g, as effectors of immune cell function has been established by the examination of cytokine production in RA patients and through the use of animal models. C57BL/6 (B6) mice that express MHC class II molecules of the b haplotype (I-A^b) are not typically susceptible to collagen-induced arthritis (CIA), the most widely studied animal model of RA. When the gene encoding IFN-g is removed by genetic deletion, however, susceptibility to CIA is conferred. In addition, T cell responses against the immunogen that …

Distinct Dna Damage Signaling In The Brain Distinguishes Atld, Nbs, And Atr-Seckel Syndrome, Erin Renee Phillips Shull

Theses and Dissertations (ETD)

DNA double strand breaks create a situation of extreme stress under which a cell must either be capable of repairing the lesions in order to continue replication or succumb to death. Not surprisingly, deficiencies in DNA repair genes often lead to human diseases frequently associated with genomic instability, cancer proneness, and neuropathology. Neurological consequences of aberrant DNA repair mechanisms vary depending upon the affected gene and the pathway in which it operates. Ataxia-telangiectasia (A-T) is the prototypical disease associated with DNA double strand break (DSB) repair deficiency and is characterized by severe neural pathology. A-T results from homozygous mutations that …

Effect Of Starter Cultures On Lactobacillus Acidophilus Survival And Gene Expression In Yogurt, Elizabeth W. Ng

Master's Theses

Probiotics, especially Lactobacillus acidophilus, strains have increasingly been incorporated into food products as dietary adjuncts due to their purported health benefits. Dairy products, especially yogurt, are frequently used as probiotic delivery systems. To realize therapeutic effects, it is important to consume a high amount of probiotics. However, maintaining a sufficient amount of viable probiotics in yogurt throughout the shelf life has been a challenge as starter cultures have shown to possess some deleterious effects on probiotic survival. The main objective of this thesis project was to determine the extent of antagonistic effects imposed by yogurt starter cultures (Lactobacillus delbrueckii ssp. …

Land Virtues, Eduardo M. Peñalver

Cornell Law Faculty Publications

This article has two goals. First, I explore some of the descriptive and normative shortcomings of traditional law and economics discussions of the ownership and use of land. These market-centered approaches struggle in different ways with features of land that distinguish it from other "commodities." The complexity of land - its intrinsic complexity, but even more importantly the complex ways in which human beings interact with it - undermines the notion that owners will focus on a single value, such as wealth, in making decisions about their land. Adding to the equation land's "memory," by which I mean the combined …

Modeling Parasitism Rate And Parasitism Risk: An Illustration Using A Colonially Nesting Songbird, The Red-Winged Blackbird Agelaius Phoeniceus, Max Post Van Der Burg, Larkin A. Powell, Andrew J. Tyre

School of Natural Resources: Faculty Publications

Ornithologists interested in the drivers of nest success and brood parasitism benefit from the development of new analytical approaches. One example is the development of so-called “log exposure” models for analyzing nest success. However, analyses of brood parasitism data have not kept pace with developments in nest success analyses. The standard approach uses logistic regression which does not account for multiple parasitism events, nor does it prevent bias from using observed proportions of parasitized nests. Likewise, logistic regression analyses do not capture fine scale temporal variation in parasitism. At first glance, it might be tempting to apply log exposure models …

Dairy Profitability 101: Milk Quality And Feed Efficiency, Alvaro Garcia

SDSU Extension Extra Archives

In very simple terms, dairy profitability can be defined as the difference between milk prices and the cost of production, multiplied by the pounds of milk produced. Thus, milk prices, the cost of production, and the pounds of milk produced are the three critical components for dairy profitability. Therefore, it is very important for producers to have a firm grasp on the three components (price, cost, and volume) of this equation and attempt to modify them in their favor. When milk prices are high and input costs low, producers should use all possible means to improve production and increase gross …

Seedlings’ Substrate Preferences In A Minnesota Old Growth Thuja-Betula Forest, Stephen C. Rossiter

Environmental Studies Honors Papers

Northeastern Minnesota’s logging history has altered the forests enough to cause concern about the reproduction of Thuja occidentalis and Betula alleghaniensis. I studied a rare old growth example of an already rare mesic Thuja-Betula forest and asked how well those species were regenerating in that mostly unaltered ecosystem. In managed forests, a lack of suitable substrate is thought to be limiting their seedling establishment so I asked which substrates the seedlings preferred in the old forest. To answer both questions, I measured the seedling densities of all canopy tree species across height classes and substrate types within twenty 100m2 plots. …

Natural Ice-Nucleating Bacteria Increase The Freezing Tolerance Of The Intertidal Bivalve Geukensia Demissa, Alexander M. Mccorkle

Biology Honors Papers

Instead of avoiding freezing, freeze tolerant invertebrates actively initiate controlled ice nucleation at relatively high sub-zero temperatures in extracellular compartments. Most produce proteinaceous ice-nucleators in their hemolymph, however the intertidal bivalve mollusc Geukensia demissa lacks this ability. Instead it utilizes at least one strain of ice-nucleation active (INA) bacteria, Pseudomonas fulva, present in seawater, to induce crystallization in the pallial fluid that fills its mantle cavity. In this study, two additional INA bacteria strains were isolated from the palial fluid of Geukensia demissa: Psychrobacter sp. and Shewanella sp. The ice-nucleation activity of both strains was characterized and Psychrobacter was found …

Strategies To Encourage And Support The Reluctant Middle School Male Reader, Wendy L. Poppema

Master of Education Program Theses

Studies (Lee, Grigg, & Donahue, 2007) show that girls outperform boys on reading tests and that boys, especially older boys, are less likely to read for enjoyment in and out of school (Scholastic, 2008). Societal pressure, lack of literacy skills, and lack of motivation are all obstacles that contribute to these findings. In order to raise test scores and the level of reading engagement, teachers, parents, and librarians need to connect these reluctant male readers with books and other reading material that they want to read. Boys prefer non-traditional texts, and though fiction is not a preference, boys crave certain …

War And Video Games, Nicholas A. Perry

Senior Honors Projects

War has been a subject of many different mediums. Through the portrayal of war, great movies have given insights on human conditions in wartime. War has also been the subject of several video games that are incredibly popular in mass culture. The difference between war movies and war games are that war games are interactive, requiring the players to act out violence in a digital form whereas movies are passive and reiterative in outcome.

There have been many criticisms of war video games ranging from their ability to condition players to violence to their role as propaganda for recruitment, but …

Starring Mark Twain And Hank Morgan: Performance In A Connecticut Yankee, Lisa Mcgunigal

Senior Honors Projects

Samuel Clemens, in his persona of Mark Twain, is recognized as one of the preeminent performers of the nineteenth century both on stage and in print. Twain clearly reveals his views on performance in his book, A Connecticut Yankee in King Arthur’s Court. In reviewing the text of the novel, I have examined the aspects and forms of performance Twain disclosed in relation to his characters. I have focused on: importance of dialect, power of costume changes, and the significance of settings.

A Connecticut Yankee (1889) describes the journeys of Hank Morgan, a time traveler from nineteenth-century Connecticut, into sixth-century …

The Social-Obligation Norm In American Property Law, Gregory S. Alexander

Cornell Law Faculty Publications

This article seeks to provide in property legal theory an alternative to law-and-economics theory, the dominant mode of theorizing about property in contemporary legal scholarship. I call this alternative the social obligation theory.

I argue that American property law, both on the private and public sides, includes a social-obligation norm but that this norm has never been explicitly recognized as such nor systemically developed. I argue that a proper understanding of the social obligation explains a remarkably wide array of existing legal doctrine in American property law, ranging from the power of eminent domain to the modern public trust doctrine. …

The Promethean, Volume 17, Contents May Be Hot, 2009, English Department, Concordia University-Portland

The Promethean

During our first meeting, I let the staff know my expectations for the 2008-2009 Promethean edition. Like previous years, I imagined fresh, bold writing and raw talent. With the same inspiration, I imagined a bolder journal; a journal with power and authenticity; a journal that would forever be memorable for the quality, quantity and impression. The Promethean staff grounded these ideas, while the contributors shaped them. I've never felt prouder of The Promethean. Graduating and leaving the position to Kristine never scared me; I knew we had the same visions, and I give all the credit to her.

A Comparative Study Of Bayesian Model Selection Criteria For Capture-Recapture Models For Closed Populations, Ross M. Gosky, Sujit K. Ghosh

Journal of Modern Applied Statistical Methods

Capture-Recapture models estimate unknown population sizes. Eight standard closed population models exist, allowing for time, behavioral, and heterogeneity effects. Bayesian versions of these models are presented and use of Akaike's Information Criterion (AIC) and the Deviance Information Criterion (DIC) are explored as model selection tools, through simulation and real dataset analysis.

Comparative Power Of The Independent T, Permutation T, And Wilcoxontests, Michèle Weber, Shlomo Sawilowsky

Journal of Modern Applied Statistical Methods

The nonparametric Wilcoxon Rank Sum (also known as the Mann-Whitney U) and the permutation t-tests are robust with respect to Type I error for departures from population normality, and both are powerful alternatives to the independent samples Student’s t-test for detecting shift in location. The question remains regarding their comparative statistical power for small samples, particularly for non-normal distributions. Monte Carlo simulations indicated the rank-based Wilcoxon test was found to be more powerful than both the t and the permutation t-tests.

Industrialization In Animal Agriculture: A Kalman Filter Analysis, Oya S. Erdogdu, Levent Ozbek

Journal of Modern Applied Statistical Methods

Studies discussing the effects of technological developments on (animal) agricultural production argue that the effective usage of chemicals and genetic engineering increase control over production processes, which in turn decreases seasonality (one significant factor defining agricultural production) significantly and brings standardization to production. Studies on broilery also show that production is not limited by nature determined seasons. Supply side changes accompanied by changes in demand have led to more healthier, standardized products. Using tools of economics and statistics, this study documents this transformation in animal agricultural production of beef, pork and milk. Results indicate decreasing seasonality, thus the industralization of …
