OBJECTIVE To retrospectively evaluate mediolateral translation of the proximal tibial segment (tibial plateau) after tibial plateau levelling osteotomy (TPLO), stabilised with three types of plate. METHOD Pre- and postoperative radiographs of 79 dogs that had TPLO surgery using three different types of plates were reviewed. Two plate types incorporated non-locking screws: Slocum (22 cases) an...
Rivers are critical links in the carbon and nitrogen cycle in aquatic, terrestrial, and atmospheric environments. Here riverine carbon and nitrogen exports in nine large rivers on the Tibetan Plateau - the "Water Tower of Asia" - were investigated in the monsoon season from 2013 to 2015. Compared with the world average, concentrations of dissolved inorganic carbon (DIC, 30.7mg/L) were high in r...
Introduction The Aristarchus Plateau (Figure 1) is a distinctive, geologically complex volcanic highland in northern Oceanus Procellarum. It is roughly diamond shaped, 170 by 220 km across, and up to 2 km higher than the surrounding mare [1, 2]. The roughly linear edges of the plateau suggest that it is fault bounded. The plateau edges are essentially radial and concentric to the center of the ...
Natural iron fertilization promotes the phytoplankton bloom that takes place on the Kerguelen Plateau in the Indian sector of the Southern Ocean. We measured Ra (T1/2 1⁄4 5.75 yr) and Ra (T1/2 1⁄4 1602 yr) in waters above the Kerguelen Plateau in order to provide information on the water-mass pathways, which in turn could help elucidate the mechanisms controlling iron fertilization in that area...
PURPOSE To investigate biometrically the differences between plateau iris configuration (PIC) eyes and primary open angle glaucoma with narrow angle eyes. METHODS A comparative study involving a case series with 20 eyes of 11 plateau iris configuration patients and 45 eyes of 27 primary open angle glaucoma with narrow angle eyes patients was done. The following measurements were taken: cornea...
INTRODUCTION Lower tidal volume ventilation in patients with acute respiratory distress syndrome (ARDS) is a strategy to reduce the plateau pressure and driving pressure to limit ventilator-induced lung injury (VILI). Several randomised controlled trials (RCTs) and meta-analyses showed that limiting both the plateau pressure and the tidal volume decreased mortality, but the optimal plateau pres...
Gamma-ray bursts (GRBs), which have been observed up to redshifts z ≈ 9.5, can be good probes of the early universe and have the potential to test cosmological models. Dainotti’s analysis of GRB Swift afterglow light curves with known redshifts and a definite X-ray plateau shows an anti-correlation between the rest-frame time when the plateau ends (the plateau end time) and the calculated lumin...
Between March 2004 and February 2005, the monthly incidence of trypanosome infections was measured in cattle from nine sentinel herds in the Adamaoua province of Cameroon. Three herds of 20 cattle each were kept on the plateau which has been cleared from tsetse flies about 10 years ago, three other herds were grazing in the tsetse infested valley whereas the last three were herded in the buffer...
During the past two decades an array of studies have shed light on potential links between the evolution of Hominids as well as Human dispersal out of Africa and episodes of abrupt climate change. Although archaeological evidences suggest that anatomically modified humans appeared in Africa between 200 and 150 ky ago, the timing of the early humans migration out of Africa remained unclear. Stra...
The Cumberland Plateau supports diverse plant communities that vary greatly across cove and plateau habitats. Unfortunately, little is known about how terrestrial invertebrate communities vary across cove andplateauhabitats andhowdisturbanceaffects these communities. Toaddress this deÞciency, we used the Ant Leaf Litter protocol to survey ant diversity on the southern Cumberland Plateau in Tenn...
