After extraction, the damping ring (DR) bunch length is eom@essed in the RTL (Ring-To-Linac) transport line to achieve the desired linac bunch length. For this, an energy spread is induced proportional to the DR bunch length, producing large, aperture filling, horizontal beam sizes in the dispersive regions of the RTL. There, nonlinear magnetic fields and wakefields cause higher order dispersio...
Background: It has been suggested, although not proven, that presence of concomitant psychiatric disorders may increase the inpatient costs for patients undergoing elective surgery. This study was designed to test the hypothesis that elective lumbar fusion surgery is more costly in patients with under treatment for depression. Methods: This is a retrospective case-control study of 142 patient...
comparison of linear dimensions and angular measurements on panoramic images taken with two machines
background and aims. panoramic radiography is a method widely used because of low absorbed dose in patients (approximately 10 times less than that in the full mouth survey), reasonable cost and time. disadvantages of this radiography technique are magnification and distortion as a result of unequal magnification, which can influence dimensional and angular measurements used in clinical dentistr...
Many studies have been conducted on the characteristics of hydraulic jumps over horizontal basins. On sloping basins, however, few such studies have been performed so that the issue requires more investigation. A significant number of studies has also been conducted on basins with positive slopes but comparatively few have been carried out on basins with negative slopes. This study was carried ...
