Seventy-three tumors of the cerebellum and fourth ventricle were analyzed by computed tomography to establish criteria for identifying the location and histology of the tumor. Brain stem tumors and metastases were excluded from the study. Tumors within the fourth ventricle are usually central in location, have a lucent halo and show no evidence of a(More)

Eight cases of vertebral chordoma, exclusive of the sacrococcygeus, are presented. The conventional radiographic signs in descending order of importance in differential diagnosis are: destruction of multiple adjacent vertebral bodies; a paravertebral or precerevical soft tissue mass; osteosclerosis, seen mainly at the periphery of the destructive lesion;(More)

Computed tomography (CT) is an effective non-invasive method of evaluating the lumbar spine in cases of suspected disc disease. In over a 3-year period in a high volume neuroradiologic practice we have observed a number of pitfalls in the diagnosis of herniated nucleus pulposus which may lead to erroneous conclusions and therefore, decrease the overall(More)

By its ability to differentiate the densities of various intracranial tissues, computed tomography is an ideal tool to investigate the postoperative course and complications of neurosurgical patients. The most important immediate postoperative complications are intracerebral edema and epidural, subdural or intracerebral hematomas. The extent of surgical(More)
We have performed low-temperature transport measurements on a GaAs two-dimensional electron system at low magnetic fields. Multiple temperature-independent points and accompanying oscillations are observed in the longitudinal resistivity between the low-field insulator and the quantum Hall liquid. The amplitudes of these oscillations can be well described(More)
The dissolution characteristics of limestones from six sources in Taiwan have been studied by using the pH-stat method in a stirred tank at 60 degrees C, pH values of 4 and 6, stirrer speeds of 500-1000 rpm, and a particle size of 75-125 microm aperture width. The dissolution rates of the limestones were found to be controlled by the mass transfer of(More)
A four-channel Ti:LiNbO(3) wavelength division multiplexer (WDM) that uses cascaded two-mode-interference dual-channel WDM waveguide structures was demonstrated. Its implementation in integrated-optic form affords ease of fabrication, voltage tunability, and the potential for combining other devices for different functions on the same chip. The device was(More)

A temperature-dependent conformational change of the active DPN-linked isocitrate dehydrogenase was observed. When initial reaction kinetic data were examined between 35 and 5 degrees, the Hill number (n) varied from 2 at higher to n approaching unity at lower temperatures, with an inflection point at 17 degrees. The presence of manganous isocitrate in the(More)
