OBJECTIVE To determine which of four methods of spinal immobilization causes the least ischemic pain. METHODS A prospective, nonblinded comparative trial was conducted at a statewide emergency medical services training facility using a convenience sample of emergency medical technician students. After lying motionless for 10 minutes, students evaluated each device using a 10-centimeter visual...

It has been shown previously that sorting n items into n locations with a polynomial number of processors requires (logn= log logn) time. We sidestep this lower bound with the idea of Padded Sorting, or sorting n items into n+o(n) locations. Since many problems do not rely on the exact rank of sorted items, a Padded Sort is often just as useful as an unpadded sort. Our algorithm for Padded Sort...

The mechanical properties of a boxing punch have been determined using several techniques. The results are consistent with the medical consequences of boxing discussed in the report of the Board of Science and Education Working Party on boxing. Data were gathered from a world ranked British professional heavyweight, Frank Bruno, as he punched an instrumented, padded target mass suspended as a b...

Padded-sorting is a task of placing input items in an array in a nondecreasing order, but with free space between consecutive elements allowed. For many applications, paddedsorting is as useful as sorting. Approximate compaction and compression are closely related problems. It is known that time complexity of padded-sorting on randomized CRCW PRAMs is considerably lower than time complexity of ...

Continued fraction absorbing boundary conditions (CFABCs) are new arbitrarily high-order local absorbing boundary conditions that are highly effective in simulating wave propagation in unbounded domains. The current versions of CFABCs are developed for the non-dispersive acoustic wave equation with convex polygonal computational domains. In this paper, the CFABCs are modified through augmentati...

was manipulated to relieve pressure on the skin over the dorsum of the foot, and a plaster-of-paris cast padded with sterilised cotton-wool was applied in the casualty-theatre, which is on the ground floor. Operation.-Next day he was operated on in theatre 1 of the main theatre suite (see figure). The skin of the ankle was incised, a large butterfly fragment of the fibula was wired, the torn jo...
