PURPOSE The hang-back suture technique has been advocated to decrease the risk of scleral perforation during strabismus surgery. In this study, we evaluated the muscle insertion site in rabbits 4 weeks after a hang-back recession was performed. METHODS Twenty-five eyes of 13 rabbits underwent hang-back recessions of between 5 and 8 mm of the superior rectus muscle. Four weeks later, the attac...

ultrasonic vibration assisted single point incremental forming (uvaspif) process is an attractive and adaptive method in which a sheet metal is gradually and locally formed by a vibrating hemispherical-head tool. the ultrasonic excitation of forming tool reduces the average of vertical component of forming force and spring-back rate of the formed sample. the spring-back phenomenon is one of the...

Web navigation relies heavily on the use of the ‘back’ button to traverse pages. The traditional back button suffers from the distance and targeting issues that govern Fitts’ Law. An alternative to the button approach is the use of marking menus—a gesture based technique shown to improve access times of commonly repeated tasks. This paper describes the implementation and evaluation of a gesture...

In the presence of back reaction, we first produce the one-loop corrections for the event horizon and Hawking temperature of the Reissner-Nordström black hole. Then, based on the covariant anomaly cancelation method and the effective action technique, the modified expressions for the fluxes of gauge current and energy momentum tensor, due to the effect of back reaction, are obtained. The result...

Synthesis of complex consonant clusters is a challenge in TTS systems, as it is difficult to ensure proper coarticulation. This problem surfaces in the synthesis of missing units in unit concatenation systems. Back-off techniques are used to synthesize these missing units. The current back-off techniques, which use smaller sub-word units to synthesize the missing unit, are found unsuitable for ...

BACKGROUND Almost one third of women suffer continuous lower back pain during labour. Evidence from three systematic reviews demonstrates that sterile water injections (SWI) provide statistically and clinically significant pain relief in women experiencing continuous lower back pain during labour. The most effective technique to administer SWI is yet to be determined. Therefore, the aim of this...

BACKGROUND Post-burn contractures are a commonly encountered problem and many techniques have been described in their treatment. Z-plasties are the commonest local flap procedure done for linear bands with adjacent healthy tissue. Our aim was to assess the use of square flap technique in axillary contractures. METHODS Ten patients with type I and II axillary contractures underwent release by...
