Continuous Convertors for Dextrose

Passive Pfc for Flyback Convertors

A new passive Power Factor Corrector (PFC) based on Valley Fill (VF) is proposed for an off-line Flyback converter. By adding an extra winding which is magnetically coupled to the Flyback transformer and electrically coupled to the VF, higher Power Factor (PF) and lower Total Harmonic Distortion (THD) can be achieved. The proposed circuit uses a high frequency inductor, low voltage capacitors t...

Glucose and insulin dynamics associated with continuous infusion of dextrose or dextrose and insulin in healthy and endotoxin-exposed horses

Dextrose prolotherapy for recalcitrant coccygodynia.

PURPOSE To present the results of dextrose prolotherapy undertaken for chronic non-responding coccygodynia in 37 patients. METHODS 14 men and 23 women (mean age, 36 years) with chronic coccygodynia not responding to conservative treatment for more than 6 months were included. 27 of them had received local steroid injections. A visual analogue score (VAS) was recorded for all patients before a...

Comparison of 5% with dextrose, 1.5% with dextrose, and 1.5% dextrose-free lidocaine solutions for spinal anesthesia in human volunteers.

The use of lidocaine in concentrations less than 5% for spinal anesthesia may be advantageous but has not been carefully studied. Lidocaine 50 mg (1.5% with dextrose and 1.5% dextrose-free) was administered to eight volunteers in a randomized, double blind, cross-over fashion. All of these subjects had previously received 5% lidocaine with dextrose using the same experimental protocol. Sensory ...

Metastability in Latches, Arbiters and Data-convertors

Real-time digital systems and asynchronous computer systems have an inherent risk of occasional failures due to metastability in various components used to control data-transfers. This possibility has been known for a long time, although it is sometimes forgotten or overlooked. There is renewed interest in asynchronous computer systems because of the prospects they offer for lower power operati...
