  • Master/slave parallel processing

    Creator:
    Larsen, Steen K.
    Abstract:
    An 8 bit microcontroller slave unit was designed, constructed, and tested to demonstrate advantages and feasibility of master/slave parallel processing using conventional processors and relatively slow inter-processor communications. An 8 bit ISA bus controlled by an 80X86 is interfaced to a logic block that controls data flow to and from...

  • Offloading of I/O transactions in current CPU architectures

    Creator:
    Larsen, Steen K.
    Abstract:
    IO transactions within a computer system have evolved along with other system components (i.e., CPU, memory, video) from programmed IO (PIO). In current mainstream systems (spanning from HPC to mobile) the IO transactions are CPU-centric descriptor-based DMA transactions. The key benefit is that slower IO devices can DMA write system...

  • Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

    Creator:
    Zhang, Yong
    Abstract:
    Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...

  • Regulation of phospholipase C-beta isozymes by calmodulin

    Creator:
    McCullar, Jennifer Star
    Abstract:
    Phospholipase C-Jβ (PLCβ) is an important effector enzyme in G-protein-coupled signaling pathways. Activation of PLCβ by Gα and Gβy subunits has been fairly well characterized, but little is known about other protein interactions that may also regulate PLCβ function. A yeast two-hybrid screen of a mouse brain cDNA library with...

  • Habitat parameters associated with the distribution of seven willow species on a stream in southeastern Oregon

    Creator:
    Gilbert, Griffith J.
    Abstract:
    Thirteen different habitat parameters were measured either quantitatively or qualitatively around seven different Salix (willow) species on a defined reach of stream on the southwestern slope of Steens Mountain in southeastern Oregon in order to both broaden the current information base of riparian ecology and inform future willow plantings aimed...

  • Suppression of Met signaling by the green tea polyphenol (-)-epigallocatechin-3-gallate (EGCG)

    Creator:
    Larsen, Christine A.
    Abstract:
    Met is a prognostic indicator of colorectal cancer patient survival. Therapies that target Met may therefore have beneficial outcomes in the clinic. Recently, EGCG was reported to suppress Met activation, although the mechanisms were not elucidated. HCT116 and HT29 human colon cancer cells were used to examine the relationships between...

  • Petrogenesis of the Steens Basalt : Variation in Source Contributions and Effects of Crustal Passage During the Onset of Columbia River Flood Basalt Volcanism

    Creator:
    Moore, Nicole E.
    Abstract:
    Continental flood basalts represent short-lived but immense blasts of mafic magma to the continental crust. The youngest and smallest continental flood basalt worldwide, the Columbia River Basalt, initiated with the eruption of the most mafic member, the Steens Basalt (~16.9 Ma). The Steens Basalt is exposed in southeast Oregon, southwest...

  • Ascorbylation- the biological relevance of covalently bound ascorbic acid

    Creator:
    Kesinger, Nicholas G.
    Abstract:
    Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'. The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...

    Creator:
    Trowbridge, A. Hayley
    Abstract:
    Author Nella Larsen and photographer James VanDerZee are two of the most canonical figures of Harlem Renaissance studies, whose respective novels and portraits have been explored extensively, if separately, by scholars. Both Larsen's 1929 novel Passing and VanDerZee's studio portraiture of the 1920s and 1930s have been read in terms...

  • Role of Plc in the germination of Clostridium perfringens food poisoning isolate SM101

    Creator:
    Bond, Colton B.
    Abstract:
    Clostridium perfringens is the causative agent of gas gangrene and the 3rd most common cause of type A food borne disease in the United States. Critical to the pathogenicity of C. perfringens is the ability of this bacterium to produce highly resistant, metabolically dormant spores that can resume metabolic function...
