Flushing the Intestinal Canal through Multiple Enterotomy Openings

Network connectivity through small openings

Network connectivity is usually addressed for convex domains where a direct line of sight exists between any two transmitting/receiving nodes. Here, we develop a general theory for the network connectivity properties across a small opening, rendering the domain essentially non-convex. Our analytic approach can go only so far as we encounter what is referred to in statistical physics as quenched...

One dimensional simulation of flushing sediment through reservoirs

Control of sedimentation in reservoirs of dams is considered to be one of the most important issues in exploitation of dams and increasing their useful life. Reservoirs act as traps for sediments and prevent transport of sediments to the river. The deposited sediments will decrease the capacity of the reservoirs so that they cannot be in use any more. Various methods are discussed in this study...

Multiple spinal canal meningiomas.

Three cases of multiple spinal canal meningiomas are presented, bringing the total number of documented cases in the American literature to nine. While the exact incidence of multiple spinal meningiomas is difficult to determine, their possible occurrence warrants careful myelographic examination of the whole spinal canal, particularly if multiple clinical levels are present. When a complete bl...

Multiple Openings and Competitiveness of Forward Markets: Experimental Evidence

We test the competition enhancing effect of selling forward in experimental Cournot duopoly and quadropoly with multiple forward markets. We find that two forward periods yields competitive outcomes and that the results are very close to the predicted theoretical results for quantity setting duopolies and quadropolies. Our experiments lend strong support to the hypothesis that forward markets a...
