BACKGROUND Femoral stress fractures tend to occur at the neck, medial proximal-shaft, and distal-shaft. The purpose of this study was to determine the internal femoral forces and moments during running. It was expected that larger loads would occur at these common sites of femoral stress fracture. METHODS Ten subjects ran at their preferred running speed over a force platform while motion cap...

A Multivariable Control System is designed for an Electromagnetic Bearing and Rotating Shaft System. The Linear Quadratic Gaussian with Loop Transfer Recovery (LQG/LTR) methodology is used to design a robust Model Based Compensator (MBC). The electromagnetic bearing consists of an electromagnetic actuator, operated in magnetic "attractive" force mode, with permanent magnet biased coils. The per...

Automotive drive Shaft is a very important components of vehicle. The present paper focuses on the design of such an automotive drive shat by composite materials. Now a days two pieces steel shaft are used as drive shaft. However, the main advantages of the present design is; only one piece of composite drive shat is possible that fulfil all the requirements of drive shaft. Two different design...

This paper presents a novel real-time crack identification method to determine the position and depth of a transverse open crack on a rotating shaft. A newly developed wireless sensor capable of being mounted directly on the shaft can be employed to monitor acceleration at different points of a shaft in a rotating coordinate system. The vibration parameters obtained from a Finite Element Model ...

conclusions due to the shorter :union: time, to some extent less complication rate and comparable functional and clinical results, the authors recommend to use the mipo technique in treating the mid-distal humeral shaft fracture. results the median of :union: time was shorter in the mipo group (4 months versus 5 months). the time of surgery and functional outcomes based on the ucla and meps sco...

Anterior dislocation of the shoulder joint with ipsilateral humerus shaft fracture is a very rare injury. Until July 2006 only 18 cases have been reported in the literature. Here we report a case of Anterior Shoulder dislocation with greater tuberosity and shaft of humerus fracture. The patient was treated by Open reduction and internal fixation of the shaft fracture followed by closed reductio...

BACKGROUND There are many ways to treat aseptic non-union of femoral shaft fractures with reported varied success rate. Amongst all these, Exchange nailing is the simplest and most successful technique for treating aseptic non union of femoral shaft fractures. We have carried out a prospective study in the Department of Trauma & Orthopaedics, Ayub Medical College Abbottabad to analyse the role ...

The adult peripheral nervous system of Drosophila includes a complex array of mechanosensory organs (bristles) that cover much of the body surface of the fly. The four cells (shaft, socket, sheath, and neuron) which compose each of these organs adopt distinct fates as a result of cell-cell signaling via the Notch (N) pathway. However, the specific mechanisms by which these cells execute their c...

BACKGROUND To study phacoemulsification probe shaft/wound and corneal surface/tip temperatures in vivo during longitudinal, torsional and combined phacoemulsification modes and their relationship to machine parameters. DESIGN This was a prospective study at Chaithanya Eye Hospital and Research Institute, Trivandrum, India (tertiary). PARTICIPANTS Twenty-two eyes of 22 patients were randomiz...

The paper presents a new approach to the parameter identification of a wind turbine shaft vibrations measured with piezoelectric sensor. The system order and unknown processes matrices are determined using the wind force as the model input and wind turbine shaft vibrations as the model output. The identified model can be used to estimate the shaft vibrations and design an early damage monitorin...
