A generic Picard-Vessiot extension for GL(n) and the inverse differential Galois problem.
(2000)Let F be a differential field with field of constants the algebraically dosed field C. Let Yij be differential indeterminates and let R = F{ Yij}[X11, ..., Xnn] be a differential ring with derivation D (Xij) = k=1n ... -
Genes required for in situ sediment survival of Shewanella oneidensis MR-1.
(2005)We determined the function of one sediment-survival gene, examining mexF in greater detail. The protein encoded by mexF shares high homology with MexF in pathogenic Pseudomonas where it has been shown to confer a multidrug ... -
Genes required for sediment fitness in Desulfovibrio desulfuricans G20.
(2007)97 genes required for sediment fitness of G20 were identified and the identification of chemotaxis genes validated our STM screening method since it would be expected to enhance sediment fitness. The growth of these sediment ... -
THE GENESIS OF THE SCOTTISH RITE PIPE ORGAN IN THE UNITED STATES THROUGH 1930
(2020-05-08)At the dawn of the twentieth century, the pipe organ played a coveted role in the civic life of the United States. In the absence of public address systems, pipe organs, with their immense power and tonal capabilities, ... -
Genetic and biochemical characterization of hydroxamate transporters in Listeria monocytogenes.
(2007)Listeria monocytogenes is a Gram-positive bacterial pathogen that can cause severe opportunistic infection in humans and animals, and iron is a virulence determinant in this pathogen. By sequence homologies, the genome of ... -
The genetic and environmental effects on hybridization between Drosophila melanogaster and D. simulans /
(The University of Oklahoma., 1971) -
Genetic and environmental influences on alcohol use: DF analysis of NLSY kinship data.
(1997)DF analyses by race produced interesting findings. Each of the groups--Whites, Blacks, and Hispanics--differed from each other in some form. In each case, the c$\sp2$ and h$\sp2$ estimates were small to moderate for both ... -
Genetic and environmental influences on the development of reproductive strategies during adolescence.
(2000)This study examined the relative importance of the conditional model and the alternative model. These models have been used to explain the development of reproductive strategies in humans. The conditional model assumes a ... -
GENETIC AND GENOMIC ANALYSIS OF BAHD ACYLTRANSFERASES THAT DECORATE CELL WALL COMPONENTS WITH PHENOLIC ESTERS AND ALTER PLANT BIOMASS RECALCITRANCE
(2018)Next generation biofuels make use of the energy stored in plant cell walls, so called lignocellulosic biomass. However, the natural resistance of plant cell walls against deconstruction, i.e., “cell wall recalcitrance”, ... -
Genetic and morphologic variation within and among populations of the black-tailed prairie dog.
(1981)Genetic variation for seven variable loci and morphometric variability for 17 cranial characters were analyzed for black-tailed prairie dogs (Cynomys ludovicianus) within and between populations in eastern New Mexico. ... -
Genetic Architecture and Influence of Switchgrass Internode Anatomy on Biofuel Production-Relevant Traits
(2022-05)Biofuels produced from plant biomass, such as switchgrass, have the potential to mitigate the increasing pace of rising atmospheric CO2 and global temperatures caused in part by the burning of fossil fuels. Biofuels produced ... -
A genetic climatic classification system of the coterminous United States as portrayed by mean monthly temperature-precipitation climographs /
(The University of Oklahoma., 1977) -
Genetic studies in a demographic framework: Annual variation, inbreeding history, and effects of isolation in a rare group of amphibians.
(2004)Rana sevosa had significantly lower genetic variation than non-isolated populations of its sister taxa. In fact, the isolated population had an observed heterozygosity that was 72% and allelic richness that was 61% of the ... -
Genetically engineered cotton in northwest Texas: Implications for farmers and rural communities.
(2006)The purpose of this research is to examine how genetically, engineered cotton has impacted northwest Texas farmers and the communities in which they live. Accounting for over 30% of the nation's total, Texas is the leading ... -
Genomic investigation of cnidarian toxin evolution
(2017-12)The phylum Cnidaria (jellyfish, hydras and anemones) was one of the earliest diverging animal groups and member species have simple, diffuse nervous systems. A trait unique to Cnidaria is specialized stinging cells ... -
Genotype x environment interactions in Drosophila melanogaster /
(1983)Chapter II. Conditional Polygenic Effects in the Sternopleural Bristle System of Drosophila Melanogaster. II. Polygene Mapping. The intrachromosomal architecture of third chromosomes isolated from lines of Drosophila ... -
The geoarchaeology of Day Creek chert: Lithostratigraphy, petrology, and the indigenous landscape of northwest Oklahoma and southwest Kansas.
(2000)This research is designed to investigate the geoarchaeology of Day Creek chert. Located in the southern Great Plains of the United States, Day Creek chert supplied an important lithic raw material for prehistoric populations. ... -
The geochemical budget of beryllium in silicic melts and superliquidus, subliquidus, and starting state effects on the kinetics of crystallization in hydrous haplogranite melts.
(2001)1. An investigation of cordierite-beryl equilibria in hydrous granitic melts using forward- and reversed-direction experiments from 675 to 900° C at 200 MPa (PH2O) has revealed the elucidate limits and mechanisms of ... -
Geochemical characterization of organic matter in Victoria Harbour sediments, Hong Kong.
(2006)The organic carbon-to-nitrogen ratio demonstrated fluctuations in the sources of organic matter throughout the Holocene unit of MBH 54/2. High fluxes in the carbon-to-nitrogen ratio may reflect strong storms, where excess ...
