Analytic hierarchy process (AHP) has been criticized considerably for possible rank reversal phenomenon caused by the addition or deletion of an alternative. While in many cases this is a perfectly valid phenomenon, there are also many cases where ranks should be preserved. Our findings indicate that using the geometric mean reduces the variance in ratings substantially; hence, yielding lower i...

Operating parameters and membrane characteristics strongly affect the performance of electrodialysis reversal systems. The most impactful factors are applied voltage, flow rate, temperature, initial feed composition, and ion exchange membrane characteristics; the pH of the feed also has an effect, although to a lesser extent. To determine more precisely how all of these factors impact performan...

background: reversal of tubal ligation is requested by some women for various reasons. the present study aims to determine the rate of pregnancy after tubal ligation reversal. case: in these case series, we reported fifteen women who requested tuboplasty after tubal ligation. in these cases reversal of tubal ligation was done in 15 women. pregnancy occurred in 4 women (26.6%). two term pregnanc...

The effect of theta pulse stimulation (TPS) on pentylenetetrazol (PTZ)-induced long-term potentiation of population spikes (PS) was studied in the hippocampal CA1 in vitro. A transient PTZ application produced a long-lasting enhancement of PS amplitude. A 3-min episode of TPS delivered at a higher intensity produced complete reversal of the PTZ potentiation when delivered during the last minute...

trichotillomania refferes compulsive hair pulling that results in considerable hair loss.many medical and nonedical therapies have been applied for treatment of this disorder. the purpose of this study was to compare the efectiveness of clomipramine, hydroxyzine, and behavior therapy (habit reversal) in the treatment of trichottillomania. to achieve this 15 patients with trichotillomania were r...

two hundred and forty patients, who had undergone vasectomy from 1977 to 1985 and subsequent vasovasostomy ,were studied for the presence of sperm-specific antibodies by using the kibrick's gelatin agglutination test. the number of successful pregnancies and the presence of agglutination were also considered in this survey. sixty-nine pregnancies occurred in total and agglutination was present ...
