Listen as descriptions of human physiology are illustrated in the eBook edition with 80 panel paintings by Philip James ROI. A viscous surface of pulped and washed colour interprets the intricate framework of muscles, arteries, bone and soft tissue, all infused with an internal dynamic of potent nervous energy. First published in 2001, the volume carried 80 colour plates of art works with descriptions of the location and function of portrayed parts.   Included: aorta, arch of atlas, arm, artery, atrium, bladder, bones, brain, branches, breast, bronchi, bulb, buttocks, canal, capillary, cartilage, cavity, cells, cervix, cleft, column, compartments, cornea, cuneiform, diaphragm, digits, discs, ducts, duodenum, ear, oesophagus, fascia, femur, fibula, finger, fissure, follicle, foot, gland, gonads, heart, heel, hip, intestine, iris, jaw, knee, knuckle, labia, labyrinth, ligament, metatarsal, mouth, neck, nucleus, orifice, pelvis, perineum, philtrum,, pubis, rectum, retina, ribcage, sacrum, scalp, shin, shoulder, skin, skull, spine, spleen, stomach, teeth, testicle, thorax, throat, thumb, tongue, veins, wrist.   Born in 1948, Bromley, Kent, England, Nicholas Philip James studied painting with Keith Vaughan and Frank Auerbach at the Slade School of Fine Art, University of London, and History of Art (MA) at Kingston University. 1.

Bio-mechanics is the disciplines of biology and engineering mechanics. It utilizes the tools of physics, mathematics, and engineering to quantitatively describe the properties of biological materials.For understanding the influence of mechanical loads on the structure,properties and function of living things, bio-mechanics is the best developed tool of mechanics. Bio-mechanics deals on design and analysis, each of which is foundation of engineering.

Signal Analysis of Quantitative Ultrasound Meas...

For the prediction of osteoporotic fracture risk quantitative Ultrasound (QUS) is an alternative to techniques like X-ray absorptiometry or magnetic resonance tomography. In QUS measurements short pulses with center frequencies of 0.5 – 1 MHz are transmitted through bone. From the received signals characteristic transfer parameters associated with mechanical bone properties are determined. Within two research projects a device has been developed to transfer this technique from peripheral sites like the heel to the proximal femur, which is a main fracture site. In doing so, the conventional signal processing techniques for the calculation of the standard QUS parameters frequently failed due to multipath transmission of sound waves in bone. Therefore, the aim of this work is the development of a signal analysis which allows for characterizing sound paths separately.Based on theoretical considerations regarding sound propagation in bone and the introduction of the standard QUS parameters, the impact of multipath transmission to the calculation of these parameters is discussed. Analytically and with simulations errors are illustrated which arise from disregarding the existence of multiple sound paths. Furthermore, the ex vivo and in vivo measurement setups are shortly presented.Main focus of this work is put on the signal analysis. For the separation of superimposed signal components from different sound paths a model-based signal analysis is adapted from the area of nondestructive material testing to this specific task, at first. This algorithm is based on the analytical description of the received US pulses in the time domain as a superposition of several Gaussianmodulated cosines with additive white noise. Applying nonlinear optimization procedures using leastsquares fits which are integrated in an iterative Space Alternating Generalized Expectationmaximization algorithm (SAGE) the difference between measured and modelled signal is minimized and, thus, the model parameters of each signal component are determined. Then, the transfer parameters are calculated from the shift of these parameters compared to a reference signal. However, this algorithm is limited to signals, which can be described as Gaussian modulated cosines in the time domain.

Design of a Hip Screw for Injection of Bone Cement
49,00 € *

Fracture to the neck of femur is frequently stabilised with a hip screw system, however the host bone is often weak or osteoporotic. This causes premature failure of the system, commonly by cut-out of the lag screw through the head of the femur. While augmentation of the fixation with bone cement improves the holding power and decreases failure rate, current methods of administering the cement are messy and inaccurate. This project proposes a lag screw design which allows for direct injection of the cement, via the lag screw itself, after the screw has been inserted and correctly positioned in the femur. A method is also suggested to reduce the risk of cement leakage into the joint space when the guide wire has punctured the head of the femur. The design uses a system of holes in the threaded section of a cannulated screw to allow delivery of cement to the desired area. Testing was conducted in a synthetic bone analogue as well as in cadaveric porcine femurs.
