The study of rotary steering drilling technology is currently one of the hot topics in the drilling engineering field. It requires accurate well trajectory control instructions when rotary steerable tools are applied to achieve the well trajectory control goal. A drilling trajectory prediction model will benefit this progress. According to the continuous beam theory, a mechanical model of push-...

Abstract Background Guidewire fracture and loss is a rare but well known feared complication of percutaneous coronary interventions. With the increasing number complex interventions procedures for chronic total occlusions, operators face new challenges boundaries, need solutions to otherwise complications increasing. Case summary We have developed simple practical method retrieving fractured lo...

A case of Dupuytren's contracture is described, in which, both clinically and histologically, knuckle pad lesions involved the extensor tendons. Surgical excision of the Dupuytren's tissue from the dorsal aspect of the proximal interphalangeal joints, freeing of the lateral extensor slips and posterior capsulotomy resulted in marked functional improvement.

Multimodal biometrics system becomes an inexorable trend in future. Multimodal biometrics overcomes many drawbacks over unimodal biometrics. Some of the drawbacks are non-universality, noisy data and spoof attack. Multimodal biometric is more efficient and accurate than unimodal system. In this paper we present a multimodal biometric recognition system using Iris and finger Inner-knuckle print....
