Background: The treatment of femoral shaft fractures has always been a focus of interest especially in children, but may still remain a clinical problem and a subject of controversy. Objective: To compare the post-operative outcomes of hip spica and flexible intramedullary nails in treatment of femoral shaft fractures in children. Material & Methods: Randomized controlled trial conducted for si...

Analysis of genotypes for genetic predisposition of diseases has profound and widespread clinical application and has become a fundamental tool in the study of molecular epidemiology. In this study, we report a convenient and completely noninvasive approach to perform genotyping using terminal cephalic hair shaft. The average and median DNA amounts purified from the hair shaft are 112 180 (1 SD...

-In the present work an attempt is made to evaluate the suitability of composite material such as E-Glass/Epoxy and HMCarbon/Epoxy for the purpose of automotive transmission applications. A one-piece composite drive shaft for automobile is designed and analyzed using ANSYS software respectively for E-Glass/ Epoxy and HM-Carbon/Epoxy composites with the objective of minimization of weight of the...

This retrospective study aimed at comparing the cost of operative treatment versus non-operative treatment in the management of isolated paediatric femoral shaft fracture, in a single Trauma and Orthopaedic unit in a district general hospital in South East England. Patients were divided into three groups according to their treatment, and the cost was analysed depending on their requirements for...

The aim of this study was to quantify and explain the effect of shaft stiffness on the dynamics of golf drives. Twenty golfers performed swings with two clubs designed to differ only in shaft bending stiffness. Wrist kinematics and clubhead presentation to the ball were determined using optical motion capture systems in conjunction with a radar device for capturing ball speed, launch angle, and...

Metacarpal and phalangeal shaft fracture fixation can be achieved by closed IM nailing. This technique provides sufficient stability to commence early unsupported joint motion and minimize soft-tissue irritation and scar formation. Stability is enhanced by proximal nail locking; a measure that extends the indications to spiral and comminuted fractures. The surgical technique is simple but requi...

The torsional stress is caused by interaction between electrical transient air-gap torque by electrical disturbances and mechanical torque of turbine-generator shaft system. If a transient shaft torque exceeds a certain threshold, the loss of fatigue life occurs and in the end it is possible to happen shaft failure. This paper discusses that which factors can damage to turbine-generator shaft a...

In this paper we consider the stability of motion an unbalanced gyroscope with a flexible shaft in gimbal suspension.Gyroscopes are used to control boom tower cranes. First, linear Hamiltonian systems differential equations. The arise transportation problems. We prove several properties matrix. Next, normalization solve system matrix equations find generating function canonical transformation. ...

It’s been known for many years that thermal temperature gradients across a rotor can alter the amplitude and phase of synchronous vibration. This is due to bowing of the shaft caused by a temperature difference between one side of the shaft and the other. The earliest published recognition of this phenomenon was by Newkirk [1], where the temperature difference was a result of frictional heating...

In order to have fault identification for the gate rotor shaft with multiple cracks effectively, the quantity identification method of the gate rotor shaft with multiple cracks based on wavelet finite element method is established and the frequency test of the gate rotor shaft based on blind source separation algorithm is analyzed. Firstly the wavelet finite element was established by combining...
