Mechanical test specimens were prepared from the cranial and caudal cortices of radii from eight horses. These were subjected to destructive tests in either tension or compression. The ultimate stress, elastic modulus and energy absorbed to failure were calculated in either mode of loading. Analysis was performed on the specimens following mechanical(More)
Through abstract movement, we are able to communicate various emotional content to users on the computer screen. This article examines movement in Theatre and Psychology and how connotative values are associated with movement. Through understanding the characteristics of movement and their various effects, the designer may better understand the complexity(More)
Twenty-five ununited coronoid processes (UCP) and 24 osteochondritis dissecans (OD) flaps were examined by light and transmission electron microscopy. Chondrocytes showed degenerative changes but remained viable and continued to secrete matrix components, even though the organisation of the matrix was altered. Differences in the histological and(More)
The behaviour of cortical bone under load is strain rate-dependent, i.e. it is dependent on the rate at which the load is applied. This is particularly relevant in the galloping horse since the strain rates experienced by the bone are far in excess of those recorded for any other species. In this study the effect of strain rates between 0.0001 and 1 sec-1(More)
Pectineus muscle resection was performed on 100 dogs with hip dysplasia. The degree of dysplasia was estimated by radiography and by joint manipulation. The effects of the procedure on 81 dogs were determined by personal reinspection (34), or by means of owner-reports (47). Improvement was noted in 80 per cent but only 35 per cent reached a high level of(More)
Contrast radiography was used to determine the position, shape, relationship and capacity of a number of tendon sheaths and bursae which have clinical significance in the horse. It was possible to establish the normal range of radiographic anatomy for these structures. Some variation in the extent and form of tendon sheaths were found between individual(More)
Contrast radiography, using a 25 per cent solution of sodium diatrizoate, has been used for the investigation of tenosynovitis and bursitis in horses. The procedure was undertaken on a series of 32 clinical cases and on specimens obtained at autopsy. Lesions affecting the extensor tendon sheaths at the carpus, the digital sheath, the tarsal sheath and the(More)
