excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

Rotodynamic multiphase pumps are usually equipped with many compression units to provide sufficient boosting pressure for the transportation of production fluid in gas oil field. It is a challenge maintain pump performance while flow parameters each stage vary due compressibility gas-liquid phase. In this article, stage-by-stage design method proposed improve capability pump. Variations investi...

fine- needle (fna) cytology of ovary is a simple method for evaluation of ovarian masses. but there is controversy about its reliability in differentiating between benign and malignant neoplasms. to evaluate the efficiacy of fna cytology in the distinction between benign and malignant masses of ovary, we examined 55 fine needle aspirations from 55 women 14-74 years of age. the aspirations were ...

We consider nonlinear boundary value problems with multiple solutions. A method is proposed for the computation of such solutions which depends crucially on known a priori qualitative information about the behavior of the solutions. The method is a two-stage method where the second stage is a shooting method and initial values of the shooting parameters are found in a first stage which approxim...
