The presence or absence of the biting midge Culicoides sonorensis Wirth & Jones (Diptera: Ceratopogonidae), a primary vector of bluetongue viruses (genus Orbivirus, family Reoviridae, BTV) in North America, was assessed on ranches and farms across the Northern Great Plains region of the United States, specifically Nebraska, South Dakota, and North Dakota, as part of a 2-yr regional study of BTV...
We report here the first blood donation positive for West Nile virus (WNV) by nucleic acid amplification testing collected in north-eastern Italy in July 2012.Partial sequencing of the WNV RNA demonstrated identity with a WNV lineage 1a genome identified in the same area in 2011 and divergence from the strain responsible for the outbreak in northern Italy in 2008–09. These data indicate that WN...
Seismic data from central Tibet have been combined to image the subsurface structure and understand the evolution of the collision of India and Eurasia. The 410- and 660-kilometer mantle discontinuities are sharply defined, implying a lack of a subducting slab beneath the plateau. The discontinuities appear slightly deeper beneath northern Tibet, implying that the average temperature of the man...
BACKGROUND Thermacarus nevadensis Marshall, 1928 is an uncommonly collected mite associated with hot spring environments in the western United States. Information on its distribution and ecology are incomplete. NEW INFORMATION In this paper, we report Thermacarus nevadensis from northern British Columbia. These records represent the first of Thermacaridae from Canada, the most northern record...
In this paper, 20 solar-activity phenomena are collected to investigate solar activity in solar cycle 21. The results obtained show that we can hardly say that either the south dominance of solar activity or the north dominance exists for solar cycle 21. It is also inferred in this paper that solar activity in solar cycle 21 has a northern bias at first, then as the cycle progresses, southern p...
Background Research has investigated the motivators and deterrents which influence medical practitioners and nurses to consider rural placements within Australia; there is a scarcity in podiatry. The authors received funding from the North Queensland Regional Training Network (NQRTN) to investigate the views of podiatrists working in northern Australia, podiatry students and placement co-ordina...
The taxonomy, osteology, phylogenetic position, and historical biogeography of the lambeosaurine hadrosaurid Magnapaulia laticaudus (new combination) are revised. The diagnosis of this species is amended on the basis on two autapomorphies (i.e., longest haemal arches of proximal caudal vertebrae being at least four times longer than the height of their respective centra; base of prezygapophyses...
