Phosphatidic Acid Binds And Stimulates Arabidopsis Sphingosine Kinases, Xuemin Wang, Liang Guo, Girish Mishra, Kyle Taylor

Biology Department Faculty Works

Phosphatidic acid (PA) and phytosphingosine-1-phosphate (phyto-S1P) have both been identified as lipid messengers mediating plant response to abscisic acid (ABA). To determine the relationship of these messengers, we investigated the direct interaction of PA with Arabidopsis sphingosine kinases (SPHKs) that phosphorylate phytosphingosine to generate phyto-S1P. Two unique SPHK cDNAs were cloned from the annotated At4g21540 locus of Arabidopsis, and the two transcripts are differentially expressed in Arabidopsis tissues. Both SPHKs are catalytically active, phosphorylating various longchain sphingoid bases (LCBs) and are associated with the tonoplast. They both interact with PA as demonstrated by lipid-filter binding, liposome binding, and surface plasmon …

The Implementation Of The Recovery Oriented Systems Of Care In Southwest Michigan, Gisele Tchamba

Research and Creative Activities Poster Day

The Recovery Oriented Systems of Care (ROSC) is in part an ecological systems theory that demonstrates comprehensive ways to meet the needs of individuals and families seeking alcohol, drug and mental health services. When compared to its alternative, Acute Care (AC) model, the ROSC provides long-term recovery outcomes, requires the participation of all stakeholders, and facilitates dialogue among service providers and clients. This study intended to increase public knowledge of the ROSC, its feasibility for practice, and its relevance for behavioral health research. Data collection was done using a purposeful sample, which consisted of N = 7 consenting adults currently …

Redeeming Proper Taste: Food As An Emblem Of Luxury In Eighteenth Century England, Hannah R. Hinkson

Masters Theses

Food: the universal language. As a platform upon which people express their worldviews, food is the most important basic ingredient to both life and social progress. Elegance, gluttony, moderation, and excess are nowhere more evident than at the dinner table; such applications are evidence of the power of food to unite and destroy entire communities. And logic suggests that because food is necessary for survival, the human condition is, in part, reflected in taste. What a person craves is an indication of that person's identity.

But the connection between the aesthetic and economic significance of food is most obvious in …

Uncertainty And Producer Fed Cattle Marketing Decisions: Theory And Evidence, Scott Fausti, Brent Lange

Economics Staff Paper Series (1969 - 2017)

The effect of carcass quality uncertainty on the structure of the slaughter cattle market is investigated. A theoretical extension of the “Theory of Factor Price Disparity” is provided. It is demonstrated that the coexistence of a risk premium wedge between pricing mechanisms (live wt., dressed wt., and grid) in conjunction with varying degrees of risk aversion across fed cattle producers explains the coexistence of multiple pricing mechanisms. It is also demonstrated that risk and risk preference provides a plausible explanation for the structure of the fed cattle market and for the variability in slaughter volume across marketing channels. Empirical evidence …

Biodeterioration Of Coastal Concrete Structures By Macro Algae - Ulva Fasciata, Stri Hari Babu Jayakumar, Rama Saravanane, Thirumalai Sundararajan

Journal of Marine Science and Technology–Taiwan

Puducherry is a coastal region in India where the growth of Ulva fasciata (Delile) is very abundant on all marine structures. Though the detrimental effect of this macro algae U. fasciata is a secondary one, its effect has to be investigated. To know its effect, the basic mechanism by which U. fasciata deteriorates concrete structures has been highlighted. To ascertain its detrimental effect on coastal concrete structures, M20 grade concrete cubes were casted and immersed in the coastal area where there is abundant growth of U. fasciata. In addition laboratory simulation has been carried out. Concrete samples collected from the …

B Cell-Deficient Mice Display Markedly Enhanced Resistance To The Intracellular Bacterium Brucella Abortus, Radhika Goenka, Michelle A. Parent, Philip H. Elzer, Cynthia L. Baldwin

Faculty Publications

Background. Brucella species are facultative intracellular bacteria that cause lifelong infections in humans and livestock. Methods. Here we evaluated the contribution of B cells in control of murine brucellosis in the more susceptible BALB/c and the more resistant C57BL/6 mice by infecting B cell-deficient mice. Results. Strikingly, in the absence of B cells in both C57BL/6 and BALB/c mice, 99% and 99.5% of the infection found in wild type mice was cleared, respectively. This augmented clearance was not reversed in either strain by passive transfer of immune serum. In C57BL/6 mice, the clearance of infection coincided with an increase in …

Wetland Management Guidelines For Nebraska's Wildlife Management Areas, Ted Lagrange, Randy Stutheit

Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts

Prior to Euro-American settlement, wetlands covered about 6% of the Nebraska landscape. Since settlement, the state’s wetlands have suffered serious decline. For example, approximately 90% of Rainwater Basin playa wetlands and 90% of the eastern saline wetlands have been destroyed or are highly degraded. Remaining wetlands are threatened by conversion to other uses (e.g. agriculture), invasive and aggressive vegetation, siltation, and lack of proper management. Only through sound management can the wetlands on our Wildlife Management Areas (WMA) be preserved for the citizens of Nebraska, as well as the native plants and wildlife dependent on them.

Turing Instability In Discrete Replicator Systems, Alex Bryce

Theses

When analyzing a discrete reaction-diffusion dynamical system, one primary area of interest is locating where in the parameter space Turing instabilities occur. It will be shown that Turing instabilities cannot occur in the react then diffuse equations if all diffusion coefficients are equal. The replicator dynamic is a system of equations that is used in evolutionary game theory applications to study behavior types in animal populations. Conditions for a Turing instability in first order discrete replicator systems will be discussed and illustrated with computer simulations of the results.

Dual-Channel Imaging System For Singlet Oxygen And Photosensitizer For Pdt, Seonkyung Lee, Martin E. Isabelle, Kristin L. Gabally-Kinney, Brian W. Pogue, Steven J. Davis

Dartmouth Scholarship

A two-channel optical system has been developed to provide spatially resolved simultaneous imaging of singlet molecular oxygen (¹O₂) phosphorescence and photosensitizer (PS) fluorescence produced by the photodynamic process. The current imaging system uses a spectral discrimination method to differentiate the weak ¹O₂ phosphorescence that peaks near 1.27 μ m from PS fluorescence that also occurs in this spectral region. The detection limit of ¹O₂ emission was determined at a concentration of 500 nM benzoporphyrin derivative monoacid (BPD) in tissue-like phantoms, and these signals observed were proportional to the PS fluorescence. Preliminary in …

Like I'M Dead, Brit Blasingame

Theses

Like I’m Dead is a collection of poetry tracing the separate lives of one speaker from the other side of catastrophe—the survivor’s side; an epitaph for a past life. The speaker’s disaster is divorce — one that has triggered in the speaker a fracturing floe of identity, a cumulatively dimming source in the process of defracturing at the demands of ongoing life, materiality, parenting, dating—

Life goes on, certainly, but where did the other go? the other life? self? Some of the poems depict the speaker coming to grips with moving on, with the fact that his daughter was born …

Determining The Composition Of The Dwelling Tubes Of Antarctic Pterobranchs, Lukasz J. Sewera

Honors Projects

Pterobranchs are a group of marine invertebrates within the Hemichordata, which share characteristics with both chordates and echinoderms.  Pterobranchs live in colonies of secreted tubes, coenicia, which are composed of a gelatinous material of unknown composition.  Visually, the tubes appear similar to the tunic of tunicates, a group of invertebrates within the Chordata. The nonproteinaceous tunic of tunicates is composed of cellulose, which is unusual.  The goal of this study was to determine the composition of the pterobranch coenicium. Some aspects of pterobranch phylogeny are still unclear even after multiple molecular and morphological studies.  Identification of any new shared characteristics …

Illusory Feeling Of Knowing In Self-Action Perception, Jonathan Brent Fonville

Electronic Theses and Dissertations Archive

The perceptual illusion known as "The Illusion of Authorship" has received much attention in recent years. It reflects a false belief that one has willed or authoered an event to occur, when in actuality it was simply coincidence or chance. Previous research has focused on motor movements and the participant's perception of their movement. Researchers have failed to expand on this illusion and apply it to other cognitive processes, such as knowledge, metacognition, memory, etc. Two experiments were conducted using an action dynamics approach, by collecting arm movement trajectories with the Nintendo Wii remote. It was predicted that (1) arm …

The Oldest High School Band In America: The Christian Brothers Band Of Memphis, 1872-1947, Patrick Joseph Bolton

Electronic Theses and Dissertations Archive

The purpose of this research is to present a detailed history of the Christian Brothers Band in Memphis, Tennessee from 1872 to 1947, the first seventy-five years of the program. In this research Iam also exploring the possibility that the band may be the oldest high school band in America, outliving bands before it and having a continuous existence since its founding (based mainly on its lineage of band directors). Furthermore, the project provides a comprehensive history of the Christian Brothers music programs, including band, choir and orchestra rosters, music awards given throughout the years, works performed by musical groups …

Dark Continent, Jonathan O. May

Electronic Theses and Dissertations Archive

Dark Continent is a collection of poetry centering on a concurrent chronology of the poet and a fictional character named Mandrake, who is an expression of the poet’s psychic territory. This work explores the nature of growing up in Zimbabwe, the duality of the self, the self in relation to danger, and how the self can be lost within the larger continent of the psyche. The work employs both formal and free verse structures, which serves to heighten the duality of the perception of the speaker in relation to the idea of tradition.

Integration Scaffolding In Hypermedia Learning, Amy Marcelle Johnson

Electronic Theses and Dissertations Archive

This dissertation project used 80 undergraduate students to examine the effectiveness of three forms of facilitation in hypermedia learning with text and diagrams about the human circulatory system: 1) signaling key terms, 2) prompted referencing of diagrammatic representations, and 3) integration scaffolding which provided facilitation in locating corresponding components within diagrams. These three experimental manipulations were compared to a control condition in which learners used the same hypermedia learning environment, without any facilitative feature in coordinating between text and diagrams. Two measures captured differences in learning: 1) a multiple choice pretest and posttest of declarative and conceptual knowledge and 2) …

Effects Of Rodent Species, Seed Species, And Predator Cues On Seed Fate, Kelly J. Sivy, Steven M. Ostoja, Eugene W. Schupp, Susan Durham

United States Geological Survey: Staff Publications

Seed selection, removal and subsequent management by granivorous animals is thought to be a complex interaction of factors including qualities of the seeds themselves (e.g., seed size, nutritional quality) and features of the local habitat (e.g. perceived predator risk). At the same time, differential seed selection and dispersal is thought to have profound effects on seed fate and potentially vegetation dynamics. In a feeding arena, we tested whether rodent species, seed species, and indirect and direct predation cues influence seed selection and handling behaviors (e.g., scatter hoarding versus larder hoarding) of two heteromyid rodents, Ord’s kangaroo rat (Dipodomys ordii) and …
