Line narrowing of terahertz vibrational modes for organic thin polycrystalline films within a parallel plate waveguide
(AIP Publishing, 2006-12-19)
Waveguide terahertz time-domain spectroscopy is used to demonstrate the narrowing of vibrational lines for a thin polycrystalline film of 1,2-dicyanobenzene in a parallel plate metal waveguide. When compared to corresponding ...
Transcriptomic changes induced by acute ozone in resistant and sensitive Medicago truncatula accessions
(BioMed Central, 2008-04-23)
Background: Tropospheric ozone, the most abundant air pollutant is detrimental to plant and animal health including humans. In sensitive plant species even a few hours of exposure to this potent oxidant (200-300 nL. L-1) ...
Identification of rat lung-specific microRNAs by micoRNA microarray: Valuable discoveries for the facilitation of lung research
(BioMed Central, 2007-01-24)
Background: An important mechanism for gene regulation utilizes small non-coding RNAs called microRNAs (miRNAs). These small RNAs play important roles in tissue development, cell differentiation and proliferation, lipid ...
Case for interdisciplinary environmental education and research
(Science Publications, 2009)
Problem statement: Interdisciplinary environmental education and research at American colleges and universities have been criticized for ambiguous focus, insufficient integration and lack of rigor. Part of the reason for ...
Novel virulence gene of Pseudomonas syringae pv. tomato strain DC3000
(American Society for Microbiology, 2005-11)
Previously, we conducted a mutant screen of Pseudomonas syringae pv. tomato strain DC3000 to identify genes that contribute to virulence on Arabidopsis thaliana plants. Here we describe the characterization of one mutant ...
Thermochemical biomass gasification: a review of the current status of the technology
(MDPI, 2009-07-21)
A review was conducted on the use of thermochemical biomass gasification for producing biofuels, biopower and chemicals. The upstream processes for gasification are similar to other biomass processing methods. However, ...
Cloning and characterization of microRNAs from wheat (Triticum aestivum L.)
(BioMed Central, 2007-06-01)
Background: MicroRNAs (miRNAs) are a class of small, non-coding regulatory RNAs that regulate gene expression by guiding target mRNA cleavage or translational inhibition. So far, identification of miRNAs has been limited ...
Quantum optical spring
(American Physical Society, 2008-07-22)
We study the dynamics of the quantum optical spring, i.e., a spring whose spring constant undergoes discrete jumps depending on the quantum state of another system. We show the existence of revivals and fractional revivals ...
Identification of novel and candidate miRNAs in rice by high throughput sequencing
(BioMed Central, 2008-02-29)
Background: Small RNA-guided gene silencing at the transcriptional and post-transcriptional levels has emerged as an important mode of gene regulation in plants and animals. Thus far, conventional sequencing of small RNA ...
Competition between electromagnetically induced transparency and Raman processes
(American Physical Society, 2006-10-05)
We present a theoretical formulation of the competition between electromagnetically induced transparency (EIT) and Raman processes. The latter become important when the medium can no longer be considered to be dilute. ...
