Preliminary study of illumination levels in university and elementary classrooms in Campina Grande, Brazil
(Science Publications, 2007)
The purpose of our study was to provide preliminary data on light levels used in university and elementary school classrooms in Campina Grande, Brazil with the aim of providing Brazilian politicians and educators with data ...
Forest floor depth mediates understory vigor in xeric Pinus palustris ecosystems
(Ecological Society of America, 2007)
Longleaf pine (Pinus palustris) woodlands and savannas are among the most frequently burned ecosystems in the world with fire return intervals of 1-10 years. This fire regime has maintained high levels of biodiversity in ...
Sensitivity of monkey B virus (Cercopithecine herpesvirus 1) to antiviral drugs: Role of thymidine kinase in antiviral activities of substrate analogs and acyclonucleosides
(American Society for Microbiology, 2007-06)
Herpes B virus (B virus [BV]) is a macaque herpesvirus that is occasionally transmitted to humans where it can cause rapidly ascending encephalitis that is often fatal. To understand the low susceptibility of BV to the ...
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 ...
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 ...
Determining returns to storage: Does data aggregation matter?
(Cambridge University Press, 2007-12)
Aggregate data are commonly used to determine returns to storage. However, recent studies have shown that aggregating data may lead to underestimated returns. This article compares aggregate and elevator data from Oklahoma ...
Microplate fluorescence assay for measurement of the ability of strains of Listeria monocytogenes from meat and meat-processing plants to adhere to abiotic surfaces
(American Society for Microbiology, 2007-08)
Listeria monocytogenes is a significant food-borne pathogen that is capable of adhering to and producing biofilms on processing equipment, making it difficult to eliminate from meat-processing environments and allowing ...
Potential use of spectral reflectance indices as a selection tool for grain yield in winter wheat under Great Plains conditions
(Crop Science Society of America, 2007-07-30)
Selection criteria that would facilitate increased genetic gain for grain yield would be considered advantageous in plant breeding programs. We evaluated the potential of spectral reflectance indices (SRI) for assessing ...
Fast light solitons in resonant media
(American Physical Society, 2007-04-05)
Using the structure of the Maxwell-Schrodinger equations in two-level systems in the transient domain, we derive both single-soliton and multisoliton (2n pi pulse) solutions associated with fast light in resonant media. ...
