Discovery of spectral variability of markarian 421 at t[clc]e[/clc]v energies
(IOP Publishing, 2002-08-10)
The detection of spectral variability of the gamma-ray blazar Mrk 421 at TeV energies is reported. Observations with the Whipple Observatory 10 m gamma-ray telescope taken in 2000/2001 revealed exceptionally strong and ...
Measuring the absolute height and profile of the mesospheric sodium layer using a continuous wave laser
(EDP Sciences, 2003-05-01)
We have developed and tested a novel method, based on LIDAR, of measuring the height and profile of the mesospheric sodium layer using a continuous wave laser. It is more efficient than classical LIDAR as the laser is on ...
Observation and quantification of in situ animal-sediment relations using time-lapse sediment profile imagery (t-spi)
(Inter-Research Science Center, 2002-01-01)
One of the controlling factors in determining colonisation and survivorship of benthic species is the physical nature of the sediment which, in turn, is regulated by the activities of the resident infauna. This study uses ...
In situ quantification of bioturbation using time-lapse fluorescent sediment profile imaging (f-spi), luminophore tracers and model simulation
(Inter-Research Science Center, 2004-01-01)
In order to link actual biological data on bioturbation to the abstract parameters in bioturbation models, high-resolution data on the frequency and lengths of particle displacements are required. The temporal variation ...
Are north atlantic alaria esculenta and a. grandifolia (alariaceae, phaeophyceae) conspecific?
(Informa UK Limited, 2001-02-01)
Alaria (Alariaceae, Phaeophyceae) is a common genus of kelps in the northern hemisphere. Fourteen species are currently recognized, of which three, Alaria esculenta (L.) Greville, A. pylaii (Bory de Saint-Vincent) Greville ...
A semantic web services architecture
(Institute of Electrical and Electronics Engineers (IEEE), 2005-09-01)
The Semantic Web Services Initiative Architecture (SWSA) committee has created a set of architectural and protocol abstractions that serve as a foundation for Semantic Web service technologies. This article summarizes the ...
Do ordering effects matter in willingness-to-pay studies of health care?
(Elsevier BV, 2002-07-01)
Manubriosternal joint dislocation in contact sport
(BMJ, 2001-11-01)
A 17 year old man developed chest pain and shortness of breath immediately after a scrummage while playing rugby football. A lateral chest radiograph showed a dislocated manubriosternal joint, with no associated injuries. ...
A cross-national study of violence-related behaviors in adolescents
(American Medical Association (AMA), 2004-06-01)
Background: Violent behavior among adolescents is a significant problem worldwide, and a cross-national comparison of adolescent violent behaviors can provide information about the development and pattern of physical ...
Disturbance of the re-os chronometer of molybdenites from the late-caledonian galway granite, ireland, by hydrothermal fluid circulation.
(Geochemical Society of Japan, 2001-01-01)
Re-Os ages were determined for molybdenites from the late-Caledonian Galway Granite in the west of Ireland. Molybdenites from three localities within the batholith, Mace Head, Murvey, and Travore, yield respective Re-Os ...
