All linear accelerometers, including the otolith organs, respond equivalently to gravity and linear acceleration. To investigate how the nervous system resolves this ambiguity, we measured perceived roll tilt and reflexive eye movements in humans in the dark using two different centrifugation motion paradigms (fixed radius and variable radius) combined with two different subject orientations (f...

h this paper, the asymptotic stability of interval neutral delay-differential systems is investigated. A delay-independent criterion for the stability of the system is derived in terms of the spectral radius. Numerical computations are performed to illustrate the result. @ 2003 Elsevier Ltd.

In order to determine the matching relationship of polymer molecular weight and reservoir permeability in ASP (alkaline/surfactant/polymer) flooding, a number of core flooding experiments with different polymer molecular weights are performed. Two types of curves for the relationship between the pressure difference and the injection pore volume multiples are obtained. One describes the characte...

conclusions hematoma block analgesia used in distal radius fractures of the elderly is a very safe and effective method that seems preferable to general anesthesia in emergency departments. objectives the aim of this study was to compare two analgesia methods including hematoma block and general anesthesia in people over 60 years in the orthopedic emergency department. methods 68 elderly patien...

BACKGROUND Distal radius fracture is the most common fracture of the upper extremity, and approximately 60,000 distal radius fractures occur annually in Korea. Internal fixation with an anatomical volar locking plate is widely used in the treatment of unstable distal radius fractures. However, most of the currently used distal radius anatomical plate systems were designed based on the anatomica...
