Aiming at the contradiction between large stroke and high precision characteristics of positioning table, a coaxial integrated macro-micro composite actuators (MMCA) with is proposed by combining voice coil motor (VCM), giant magnetostrictive actuator(GMA). In order to increase macro-motion stability reduce fretting error, its structural parameters are optimized finite element analysis, optimal...

The outward angulation of elbow with supinated forearm is cubitus varus deformity. This deformity is often seen as sequelae of malunited supracondylar fracture of humerus in paediatric age group of 5e8 years. The deformity is usually non-progressive, but in cases of physeal injury or congenital bony bar formation in the medial condyle of humerus, the deformity is progressive and can be grotesqu...

A conceptual design of Stirling engine suitable for onboard aircraft application is the motivation behind this study. The aim to evaluate suitability system be integrated in as part energy contributor by recycling waste thermal energy. parametric evaluation an established Wobble-Yoke Engine state space model was performed determine a pre-compensator that able produce highest power output given ...

A 21-yr old lady presented with primary amenorrhea and short stature for evaluation. She had a wide carrying angle (Cubitus valgus) and a typical deformity at the wrist joint (Fig. 1) which was evaluated. There were no other dysmorphic features. She was found to have high serum FSH and low serum estradiol with streak gonads on ultrasound. Karyotype was 45 XO. She was diagnosed to have Turner’s ...

capsular contraction is a frequent complication following breast augmentation. on the other hand, capsular weakness, a not widely recognized complication, may occur around the implant. a weak capsule allows the migration of the prosthesis to the lateral region of the thoracic region or inferiorly, towards the abdomen, due to gravitational forces. the cause of capsular weakness remains unresolve...

OBJECTIVE Asymmetrical skull deformity is frequently seen in children with cerebral palsy, and may contribute to postural abnormalities and deformities. The aim of this cross-sectional- survey was to determine the frequency of asymmetrical skull deformity and its correlation with clinical parameters. METHODS A 10-item checklist for asymmetrical skull deformity, postural abnormalities, and def...

objective:in this study, we assess long-term effects of vertical dome division (v.d.d) and suture techniques in patients with bulbous nose deformity and then compare the efficiency of these methods. material and methods: in this study 70 patients with bulbous nose deformity were divided into two equal groups of a and b in which group a with suture (transdomal and interdomal) technique and grou...
