BACKGROUND The colposcopy-directed punch biopsy is widely used in the management of women with abnormal cervical cytology; however, its accuracy compared with definitive histology from an excision biopsy is not well established. OBJECTIVES To assess the accuracy of the colposcopy-directed punch biopsy to diagnose high-grade cervical intraepithelial neoplasia (CIN) by performing a systematic r...

A solution is presented to a doubly mixed boundary value problem of the torsion of an elastic layer, partially resting on a rigid circular base by a circular rigid punch attached to its surface. This problem is reduced to a system of dual integral equations using the Boussinesq stress functions and the Hankel integral transforms. With the help of the Gegenbauer expansion formula of the Bessel f...

In order to be successful in karate, it is necessary to apply the highest punch impulse at impact while maintaining dynamic body stability during the entire action. Here we test two different techniques to execute a specific karate punch and we compare expert and novice performances to explore the punch efficacy at different skill levels. Each participant, standing on a force platform, was aske...

This paper presents evaluation and effect of blank radius on radial stresses through mathematical formulations in hydroforming deep drawing process using castor oil medium. Hydraulic pressure can enhance the capabilities of the basic deep drawing process for making cups. In hydroforming deep drawing process, applying the hydraulic pressure on blank periphery in radial direction. It is obtained ...

The Double Punch test, an indirect traction test, is simulated numerically considering two different models (the nonlocal Mazars damage model and an heuristic crack model with joint elements). The test was designed to measure indirectly the tensile strength of concrete, hence, through these two numerical models, we are able to assess the tensile strength numerically. Experimental results presen...
