Construction and use of bacterial DNA microarrays based on an optimized two-stage PCR strategy
(BioMed Central, 2003-06-12)
Background: DNA microarrays are a powerful tool with important applications such as global gene expression profiling. Construction of bacterial DNA microarrays from genomic sequence data using a two-stage PCR amplification ...
Contributions of leaf rust resistance and awns to agronomic and grain quality performance in winter wheat
(Crop Science Society of America, 2003-09)
Wheat (Triticum aestivum L.) cultivars grown in the Great Plains usually bear awned spikes for their putative value to grain yield and quality. Awnletted cultivars are generally limited to forage-only systems. We hypothesized ...
Optimal stocking density for dual-purpose winter wheat production
(Cambridge University Press, 2003-04)
Dual-purpose winter wheat production is an important economic enterprise in the southern Great Plains of the United States. Because of the complex interactions involved in producing wheat grain and beef gain from a single ...
Influence of portland cement characteristics on alkali silica reactivity
(Transportation Research Board, 2003)
The findings of this study which evaluated 21 portland cements identified K2O and Na2Oeq as significantly contributing to ASR expansion with a less strong correlation to SO3 content The conclusions are based on results of ...
Terahertz studies of carrier dynamics and dielectric response of n-type, freestanding epitaxial GaN
(AIP Publishing, 2003-04-28)
We report the characterization of the complex conductivity and dielectric function of GaN by terahertz time-domain spectroscopy. Transmission measurements are performed on an n-type, 180-um-thick, freestanding GaN crystal. ...
Prevalence of Escherichia coli O157 in cattle feeds in Midwestern feedlots
(American Society for Microbiology, 2003-09)
Comparisons of enrichment methods (with or without antibiotics and with or without a preenrichment step) using gram-negative (GN) broth or tryptic soy broth (TSB) were conducted with feeds inoculated with Escherichia coli ...
Using both sociological and economic incentives to reduce moral hazard
(Western Agricultural Economics Association, 2003-08)
Economists tend to focus on monetary incentives. In the model developed here, both sociological and economic incentives are used to diminish the apparent moral hazard problem existing in commodity grading. Training that ...
THz transverse electromagnetic mode two-dimensional interconnect layer incorporating quasi-optics
(AIP Publishing, 2003-11-03)
We report the demonstration of a planar THz interconnect layer capable of transmitting subpicosecond pulses in the transverse electromagnetic (TEM) mode over arbitrarily long paths with low absorption and no observable ...
Characterization of Anaplasma marginale isolated from North American bison
(American Society for Microbiology, 2003-08)
Anaplasma marginale (Rickettsiales: Anaplasmataceae), a tick-borne pathogen of cattle, is endemic in tropical and subtropical regions of the world. Although serologic tests have identified American bison, Bison bison, as ...
