In the present study, the effect of tail fat on recovery times in intact sheep and sheep with a ligated median sacral artery following similar anesthetic exposure with isoflurane was investigated. This study was performed using seven healthy fat-tailed Iranian Lori-Bakhtiyari ewe lambs. The lambs were anesthetized twice at two week intervals (the experiment was performed in two stages). After m...

iontophoresis of epinephrine for assessment of neuromuscular junction response is a new technique that can improve diagnose of neuromuscular dysfunction. the purpose of this study was to investigate the effects of iontophoresis of epinephrine on neuromuscular junction response. iontophoresis of epinephrine solution (1mg/ml), sodium chloride, calcium gluconate, epinephrine with sodium chloride a...

In this paper a novel method to realize the synchronization process in case of 32-QAM will be presented. The system is based on the times-n carrier recovery and doesn’t depend on data decision. Starting from the Park and Ahn method which tracks, after a non linearity, the carrier recovery only for the in-phase symbols of a 16-QAM modulation, the proposed method combines a Phase Lock Loop and a ...

The performance of decision feedback equalizers (DFE’s) working on a noiseless channel with correct tap weights is studied. We show that the space of channel parameters can accordingly be partitioned into a finite number of sets. The error recovery performance of a DFE is the same for all DFE’s within one such set, and is determinable. We also discuss some tight bounds for recovery time statist...

The saturation-recovery method using two and three recovery times is studied for conditions in which the sum of recovery times is 1.5T(1) to 3T(1), where T(1) is the longitudinal relaxation time. These conditions can reduce scan time considerably for long T(1) species and make longitudinal relaxation rate R(1) (R(1) = 1/T(1)) mapping for body fluids clinically feasible. Monte Carlo computer sim...
