Abstract The influence of bottom roughness on the development lock-release gravity currents is investigated through laboratory experiments using Particle Image Velocimetry. represented by arrays vertical LEGO bricks with a constant spacing while varying $$\lambda $$ ? , relative height elements to current dep...

the development of combination therapy is a coherent approach in severe pain treatment. the present study investigated the antinociceptive effect of pregabalin alone and in combination with tramadol in acute pain modeling. therefore, three groups of male mice received either pregabalin (1 to 400 mg/kg), tramadol (10 to 80 mg/kg) or their combination intraperitoneally. then latency time, maximum...

conclusions according to our findings, 3% equisetum arvense ointment promoted wound healing and relieved pain during the 10-day period after episiotomy. since this study was the first to assess the effects of equisetum arvense ointment on wound healing and pain intensity following episiotomy in humans, further research is warranted to fully clarify the beneficial effects of prepared ointment. r...

transcutaneous electrical nerve stimulation (tens) is an analgesia inducing method with increasing applications in clinical procedures. in this study we tried to evaluate the role of the adrenergic system and its different adrenoceptor subtypes in tens-induced analgesia. two types of low and high frequency electrical stimuli were used in rats through needle electrodes, inserted at the base of t...

calendula of.cinalis (asteraceae) is widely used in traditional medicine as an anti-in.ammatory agent and has also been reported to have anti-bacterial, anti-fungal and anti-viral activities.  sesquiterpene glycosides, saponins, triol, triterpenes and .avonoids are observed in its composition. the present study was designed to evaluate the antinociceptive effect of hydro-alcoholic extract of ca...

The general theory of surface NMR imaging of large electromagnetically active systems is considered, motivated by geophysical applications. A general imaging equation is derived for the NMR voltage response, valid for arbitrary transmitter and receiver loop geometry and arbitrary conductivity structure of the sample. When the conductivity grows to the point where the electromagnetic skin depth ...

Carved turns with alpine skis are investigated. During the movement of a ski, snow is loaded and unloaded. Compacted snow is not elastic, i.e. deformations remain. Such effects are modeled by a hypoplastic constitutive equation. During a turn the shovel digs into the snow and the tail maintains nearly the same penetration depth as the part under maximum load. This results in a higher resistance...
