Background: Pre-anesthetic medication is often required in children to provide anxiolysis and to lessen the psychological impact of hospitalization and procedures. In this study, we compared the effects of intravenous ketamine versus thiopental on the separation anxiety and emergence agitation in children undergoing tonsillectomy/adenoidectomy. Methods: Eighty-two children aged 2-8 years schedu...

Rotary drilling belongs to the key methods of rock separation not only in mining, but also in wider areas of geotechnologies 1, 2 . The most efficient separation of rocks is in so-called volume area which can be achieved with the correct choice of work tool and work mode while taking into account the geomechanical properties of rock separation. Theoretical research of rock separation by rotary ...

national security and territorial administration, the most basic principle of any political system. in this regard, the divisions of the territorial office of the most excellent strategy for space and maintain the integrity and strengthening internal solidarity and ultimately increase the coefficient of national security. according to the principle of cultural similar in discussing the dramatic...

We compare the area, peak separation, and width of the H and O elastic peak for light and heavy water, as observed in spectra of keV electrons scattered over large angles. Peak separation is well reproduced by the theory, but the O:H area ratio is somewhat larger than expected and is equal to the O:D area ratio. Thus no anomalous scattering from H was observed. Only minor differences are observ...

Objective: In spinal cord stimulation, neurosurgeons increasingly tend to implant dual leads. Dual leads (longitudinal bipole/tripole) provide medio-lateral control over the recruited dorsal column (DC) area by steering the injected cathodal currents. However the DC recruited area is suboptimal when dual aligned leads straddling the midline programmed as longitudinal guarded cathodes (+-+) are ...

Safety levels are a vital concern as new technologies and procedures are introduced into the National Airspace System. Despite a wealth of information from flight operations and testing programs, there is no accepted method to quantify the relationship between safety levels and aircraft separation standards in the terminal area. This paper presents a modeling approach to quantify the risk assoc...
