Kong (made with the Department of Obstetrics and Gynaecology) and studies on the incidence, biochemical and genetic charac- teristics of Cooley's anaemia and erythrocyte glucose-six-phosphate dehydrogenase deficiency were completed. The Paediatrics Unit continued its investigations on chromosomal abnormalities in con- genital anomalies and intersex. With the Department of Pathology it also conducted clinical and experimental studies on the nephrotic syndrome.
Two projects in the Department of Orthopaedic Surgery nearing completion at the end of the year were the blood supply of the femoral head throughout the healing process of fractures of the femoral neck, and the blood supply of the growing human spine and the sources of nourishment of the intervertebral disc. Other investigations included those into the blood supply of femoral head in the growing Chinese in relation to congenital dislocation of the hip and Perthes' disease, and the re-vascularization of bone grafts following anterior spinal fusion in dogs.
In the Faculty of Engineering and Architecture, the Department of Architecture continued its comparative analyses into the problems of housing particularly low-cost housing evolving new approaches in both planning and design. In the Department of Civil Engineering considerable use was made of an electronic digital computer for studies in the field of high building. Investigative work covered the influence of member stiffness on multi-storey framed structures and new methods for analysis and design of large foundation rafts. A start was made on constructing a 100-foot tall experimental building which will be used to measure the effects of typhoon- strength winds on tall buildings.
The Department of Electrical Engineering carried out research on power systems. These included non-linear analysis of power net- works and system analysis using computational aids such as the digital computer and the AC network analyser. In addition work was done on the two-axis excitation of alternator and frequency- control servomechanisms in the BEAMA electrical machines laboratory; the effects of saturation on synchronous machine reactances; and the stability of control systems and effects of time delays on such control system performance. The Department of Mechanical Engineering made hydraulics models of two river
