The purpose of this study was to clarify the influence of muscle-tendon complex stretch on electromechanical delay (EMD) in terms of the extent of tendon slack in the human medial gastrocnemius (MG). EMD and MG tendon length were measured at each of five ankle joint angles (-30, -20, -10, 0, and 5 degrees : positive values for dorsiflexion) using percutaneous electrical stimulation and ultrason...

Hip distraction is necessary for safe arthroscopic entry into the hip joint. Achieving sufficient distraction is difficult in exceedingly tall patients (>190.5 cm) because of size limitations of currently available hip distraction systems. Inadequate distraction can delay the surgical procedure and potentially lead to complications. By repurposing a foam head-positioning block, we report a safe...

PURPOSE To compare the axial length (AL), anterior chamber depth (ACD) and intraocular lens power (IOLP) of IOLMaster and Ultrasound in normal, long and short eyes. METHODS Seventy-four normal eyes (≥ 22 mm and ≤ 25 mm), 74 long eyes (> 25 mm) and 78 short eyes (< 22 mm) underwent AL and ACD measurements with both devices in the order of IOLMaster followed by Ultrasound. The IOLP were calcula...

OBJECTIVES To report the keratometry data of pediatric cataractous eyes (randomly selected single eye of bilateral cases; cataractous eye of unilateral cases) and to compare the keratometry data of the unilateral cataractous eye with the corresponding noncataractous fellow eye. METHODS Retrospective review of preoperative data of patients who had undergone cataract surgery before 18 years of ...

upon by me the next morning-. Amputation by the modified circular method was performed a few inches below the shoulder joint, and a drainage tube inserted. The following are brief notes of this case after operation:? 28-7-26. Temperature 102.5 ?F in the morning, and 103?F in the evening. One pint of saline given intravenously. Blood films examined for malarial parasites with negative result. 10...

PURPOSE To evaluate the association between the AL/CR ratio and refractive state and explore the effectiveness of this ratio in the assessment of myopia, especially when combined with uncorrected visual acuity in schoolchildren among whom myopia is common. METHODS Cross sectional study. 4686 children from 6 primary schools, aged from 6 to 12 years were selected using the clustered-stratified ...

PURPOSE To compare the ability of two optical biometers to acquire the axial length (AL) measurement in cataractous eyes. METHODS This prospective, comparative, single-center study comprised 105 eyes (63 patients). AL was acquired by the composite mean value of 20 measurements (composite-20 IM) and five measurements (composite-5 IM) (IOLMaster(®) 500 version 7.1 software), and the standard me...

A CASE OF CYSTIC TUMOUR; OPERATION. By G. D. MacReddie, Esq., Civil Surgeon, Uurdui. Jhubba Thakook, aged 35 years, was admitted into the Hurdui Dispensary on the 9th December, 1872, with a soft tumour, the size of an orange, at the back of the right elbow joint. He stated that eighteen years ago he received a bullet in his arm; a cicatrix about two inches higher up on the posterior aspect of t...

Dynamic etching methods for fabricating fibre optic tips are explored and modelled. By vertically translating the fibre during etching by an HF solution under an organic protective layer, a variety of tip shapes were created. The probe taper lengths, cone angles and geometrical probe shapes were measured in order to evaluate the dynamic meniscus etching process. Fibre motion, etching rate, meni...

This paper starts with developing kinematic and dynamic model of a snake shape robot in serpentine locomotion and finishes with actual experimentation. At the beginning the symmetrical and unsymmetrical serpenoid curves are introduced. Kinematics and dynamics of a snake robot on flat and inclined surfaces are obtained for a general n-link robot. SimMechanics toolbox of MATLAB software is employ...
