S U M M A R Y This paper demonstrates that it is possible to use measurements of the Doppler spectrum width from a highresolution radar to obtain quantitative estimates of dissipation rate during the passage of precipitating frontal zones. Using the high-resolution Chilbolton radar, this method has been applied, for the first time, to infer the rate at which kinetic energy is dissipated by turb...

BACKGROUND To evaluate the analgesic efficacy on defined areas of the abdomen and back after ultrasound-guided subcostal transversus abdominis plane (TAP) block using 0.25% levobupivacaine 0.5 mL/kg. METHODS Twenty patients undergoing elective laparoscopic cholecystectomy, between 20 and 60 years of age with operative time <1 hour, received subcostal TAP block using 0.25% levobupivacaine 0.5 ...

Originating in a tropical climate, maize has faced great challenges as cultivation has expanded to the majority of the world's temperate zones. In these zones, frost and cold temperatures are major factors that prevent maize from reaching its full yield potential. Among 30 elite maize inbred lines adapted to northern China, we identified two lines of extreme, but opposite, freezing tolerance le...

[1] Subduction zones alter the upper plate in a variety of ways, including metasomatism via slab-derived fluids and accretion of exotic terranes. These processes should produce distinctive seismic signatures, as seismic velocities are sensitive to compositional variations. A new method is developed to estimates depths to interfaces and Poisson’s ratio (Vp/Vs ratio) for dipping layered structure...

Earth is the only known planet with subduction zones and plate tectonics, and this fact demonstrates that special conditions are required for this mode of planetary heat loss. Sinking of cold, dense lithosphere in subduction zones is the principal plate-driving force, so plate tectonics could not have begun until Earth cooled sufficiently to allow lithosphere to collapse into the underlying ast...

Hibiscus rosa sinensis, a member of the Malvaceae family, is widely cultivated in the tropics as an ornamental plant. It is often planted as a fence or hedge plant, and has several forms of flowers with varying colours. It is also used in traditional medicine to induce abortion, ease menstrual cramps, assist in childbirth and relieve headache, fever and inflammation. In this study, we evaluated...

Livestock are facing various life threatening hazards notably infectious (parasitic, bacterial, viral, protozoal, fungal) and noninfectious like metabolic diseases, poisoning and other miscellaneous origin. Ethiopian people especially farmers and traditional animal healers have been using traditional methods to treat both human and their livestock diseases for generations. Traditional medicine ...

The side-blotched lizard (Uta stansburiana) is one of the most common lizards along the Colorado River corridor through the Grand Canyon (Warren and Schwalbe 1986). During our trip down the river, we saw numerous side-blotched lizards, despite the cold spring weather; they were by far the most frequently observed lizard species. Their colors were variable and bright, including shades of brown, ...

Urban parks are the main place for physical activities, generating numerous benefits to enhance human well-being. Many studies have investigated impacts of landscape features on park visitation but ignored their seasonal and diurnal variations. Taking Hunan Martyr Park in China as an example, this study aims assess variations density. We quantified density 109 activity zones both daytime nightt...

In previous work we injected mitotic cells with fluorescent tubulin and photobleached them to mark domains on the spindle microtubules. We concluded that chromosomes move poleward along kinetochore fiber microtubules that remain stationary with respect to the pole while depolymerizing at the kinetochore. In those experiments, bleached zones in anaphase spindles showed some recovery of fluoresce...
