16 When increasing the rates of subcritical flow on gentle slopes, the bed successively produces 17 ripples, dunes and flat beds. Antidunes (defined here as all bed undulations for which the 18 surface gravity waves are in phase with the bed profile) appear only in high flow rates and 19 may be found in some extreme natural flow events. Inversely, on steep slopes flume 20 experiment (S≥1% appro...

Restricted by the rolling terrains of mountainous areas in western parts of China, long steep downgrades are very common in mountainous freeways. Influenced by the factors like high altitude, big elevation differences, and the severe weather condition e.g. black ice, heavy snow and thick fog, most long steep downgrades turn to traffic accident prone sites. Moreover, once traffic accident happen...

Gonorrhoea continues to be a significant health challenge in Greenland. The aim of this study was to describe the development of gonorrhoea in Greenland through time including incidence rates and previous measures taken to address the challenge. A systematic literature search in PubMed, Embase and The Cochrane Library was conducted. Furthermore, local archives were searched in the Health Clinic...

The role of a photospheric component and of pair breakdown is examined in the internal shock model of gamma-ray bursts. We discuss some of the mechanisms by which they would produce anomalously steep low energy slopes, X-ray excesses and preferred energy breaks. Sub-relativistic comptonization should dominate in high comoving luminosity bursts with high baryon load, while synchrotron radiation ...

The effects of different sources of carbon, nitrogen and some of trace elements on cultivation of Bacillus thuringiensis H14 were studied. Glucose, glycerol, sodium acetate, (NH4)2SO4, corn steep liquor, yeast extract, hydrolyzed casein, Ca2+, Mg2+ and Mn2+ were the main parameters evaluated by Plackett-Burman statistical method. All el...
