## Abstract Twenty patients with pelvic abscesses diagnosed either at surgery or from typical clinical findings underwent sonography. Seventeen of the twenty patients had inflammatory processes of gynecological origin. In the main, two patterns were observed. The more common pattern was a small, ro
This paper introduces a methodology to quantify the significance of changes in certain rock mass characteristics. The developed method can be applied to all data sets that consist of parameters classified into categories. The tools are developed from the principles of engineering geological rock mas
The propagation characteristics of blast-induced shock waves in a jointed rock mass have been monitored and studied. Accelerometers were set up on a rock surface along three lines, at 0Π, 45Π and 90Π with respect to the orientation of the predominant joint strikes. Cylindrical charges were detonated
In view of the effect of fissure water in fractured rock mass on the strength of rock mass in engineering projects, we prepared specimens of cement mortar to simulate saturated rock mass with continuous fractures of different slope angles. By exerting static and dynamic loads on the specimens, the m
## Abstract The ultrasonic characteristics of bilomas are reviewed in five patients, one of whom was also studied with computed xβray tomography. Certain features not previously reported should aid in differentiating bilomas from other intraβabdominal fluid collections.
