PURPOSE: To evaluate the magnetic resonance (MR) imaging findings of os acromiale in rotator cuff disease. MATERIALS AND METHODS: Retrospective analysis was performed of 10 shoulder MR studies of 10 patients older than 25 years with os acromiale. The

To determine and describe the clinical, radiographic, and toxicity profile in a cohort of rheumatoid arthritis patients receiving weekly oral methotrexate (MTX) over a mean period of 90 months, and to compare and contrast these data with our previous

As a first step in the construction and testing of a theoretical model of lightning initiation, measurements have been made of the ambient electric field Eo required to support the long-range propagation of corona streamers as a function of dry air p

Seventy-nine magnetic resonance (MR) studies of the knee were reviewed in an evaluation of the ability of MR imaging to demonstrate arthroscopically proved anterior cruciate ligament (ACL) tears. MR findings were also compared with the findings of tw

Experiments are described in which the ambient electric field required for sustained positive corona streamer propagation is determined as a function of dry air pressure and water vapor partial pressure. This critical field varies approximately as th

Experiments are described in which positive streamers propagate within a uniform field region having an applied electric field greater than the minimum value needed to cause streamers to bridge the interelectrode gap. Under these conditions exponenti

A numerical model is used to calculate the electric field enhancement in a thundercloud due to the propagation of a growing system of positive corona streamers, such as might be initiated by a hydrometeor. These streamers intensify if the ambient ele

The interactions between positive corona streamers and droplets atomized from a water and glycerin solution have been studied by means of the Lichtenberg figure technique. The results indicate that a droplet with a radius greater than approximately 5
