Gas/particle flow behavior in the riser section of a circulating fluidized bed (CFB) was simulated using a computational fluid dynamics (CFD) package by Fluent Inc. Fluid Catalytic Cracking (FCC) particles and air were used as the solid and gas phases, respectively. A two-dimensional, transient and isothermal flow was simulated for the continuous phase(More)
In interventional radiology, inserting a needle to perform a biopsy requires a high haptic sensitivity. The traditional learning methods based on observation of skilled clinicians and training on real patients are questionable. Virtual Reality (VR) surgical simulators have previously been shown to be efficient for training. However, there is a lack of(More)
OBJECTIVE To prospectively evaluate the effect of pump-infused intrathecal baclofen infusion (ITB) in therapeutic doses on sleep quality and on daytime and nighttime respiratory function in patients with severe spasticity. METHODS We prospectively evaluated 20 consecutive patients (mean +/- SD age 45 +/- 13 years). We assessed spasticity and obtained(More)
