Identification of Campylobacter jejuni genes involved in the response to acidic pH and stomach transit
(American Society for Microbiology, 2008-03)
Campylobacter jejuni causes food- and waterborne gastroenteritis, and as such it must survive passage through the stomach in order to reach the gastrointestinal tract. While little is known about how C. jejuni survives ...
Inducing disallowed two-atom transitions with temporally entangled photons
(American Physical Society, 2004-08-25)
Two uncoupled two-level atoms cannot be jointly excited by classical light under general circumstances, due to destructive interference of excitation pathways in two-photon absorption. However, with temporally entangled ...
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 ...
Improving the psychology undergraduate curriculum in developing countries: A personal note with illustrations from Brazil
(Science Publications, 2006)
In this article we suggest various ways in which the undergraduate curriculum for psychology students can be improved in developing countries. Suggestions based on the author's experience in the northeast of Brazil include ...
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 ...
Plastic ribbon THz waveguides
(AIP Publishing, 2000-10-01)
We report an experimental and theoretical study of single mode, guided wave propagation in plastic ribbons. Using cylindrical THz optics, we obtain excellent quasioptic coupling between freely propagating THz waves and a ...
Double bubbles in S^3 and H^3
(2008-11-20)
We prove the double bubble conjecture in the three-sphere S3 and hyperbolic three-space H3 in the cases where we can apply Hutchings theory: 1) in S3, each enclosed volume and the complement occupy at least 10% of the ...
Cognitive rigor: Blending the strengths of Bloom's taxonomy and Webb's depth of knowledge to enhance classroom-level processes
(2009-03-07)
To teach the rigorous skills and knowledge students need to succeed in future college entry courses and workforce training programs, education stakeholders have increasingly called for more rigorous curricula, instruction, ...
Sequence comparisons of plasmids pBJS-O of Spiroplasma citri and pSKU146 of S. kunkelii: Implications for plasmid evolution
(BioMed Central, 2005-12-07)
Background: Spiroplasma citri BR3-3X and S. kunkelii CR2-3X cause serious diseases worldwide on citrus and maize species, respectively. S. citri BR3-3X harbors a plasmid, pBJS-Original (pBJS-O), that encodes the s piroplasma ...
