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 ...
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 ...
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. ...
Price survey comparison of alcoholic beverages with the five basic food groups in Paraiba, Brazil
(Science Publications, 2006)
The study of alcohol abuse is relatively new in Brazil. Government estimates suggest that 11.2% of the Brazilian population is alcohol dependent. Problems associated with alcohol dependence include domestic violence, ...
Class of solitary wave solutions of the one-dimensional Gross-Pitaevskii equation
(American Physical Society, 2006-05-19)
We present a large family of exact solitary wave solutions of the one-dimensional Gross-Pitaevskii equation, with time-varying scattering length and gain or loss, in both expulsive and regular parabolic confinement regimes. ...
Generation of Werner states via collective decay of coherently driven atoms
(American Physical Society, 2006-02-08)
We show deterministic generation of Werner states as a steady state of the collective decay dynamics of a pair of neutral atom coupled to a leaky cavity and strong coherent drive. We also show how the scheme can be extended ...
Measured long-ranged attractive interaction between charged polystyrene latex spheres at a water-air interface
(American Physical Society, 2006-08-15)
We report results of a systematic experimental study of interactions between charged polystyrene (PS) latex spheres at a water-air interface. Optical observations of stable bonded particle clusters and formation of circular ...
AlgT gene of Pseudomonas syringae pv. glycinea and new insights into the transcriptional organization of the algT-muc gene cluster
(American Society for Microbiology, 2006-12)
The phytopathogenic bacterium Pseudomonas syringae pv. glycinea infects soybean plants and causes bacterial blight. In addition to P. syringae, the human pathogen Pseudomonas aeruginosa and the soil bacterium Azotobacter ...
Effect of essential oil from citronella and alfazema on fennel aphids Hyadaphis foeniculi Passerini (Hemiptera: Aphididae) and its predator Cycloneda sanguinea L. (Coleoptera: Coccinelidae)
(Science Publications, 2006)
The essential oil of plants is used as an alternative to pesticides for the control of aphids. We study the effect of the essential oils of citronella and alfazema on aphid populations in the laboratory and in the field. ...
