摘要:

With their usual thoroughness the French have attacked the proliferation of customised equipment produced by various Research and Development Centres by establishing a National Centre for Hospital Equipment. This has been recently reported in theRevue Européenne de Biotechnologie Medicale[1].

摘要:

SummaryIn conventional radiology the introduction of image intensifiers and television has contributed greatly to the accuracy of radiological diagnosis in a number of fields. For example in diseases of the heart and vascular system the development of sophisticated radiological methods of diagnosis has assisted in the spectacular advances in cardio-vascular surgery.The introduction of non-invasive methods of imaging including CT scanning, diagnostic ultrasound, scintiscanning and nuclear magnetic resonance has substantially assisted in patient management.The impact of CT scanning in diseases of the nervous system has been spectacular and it is likely that scanning by nuclear magnetic resonance will make a similar contribution. Diagnostic ultrasound has virtually replaced conventional radiography in obstetrics and its value is being established in other systems. Investigation by radioisotopes is very useful particularly in deseases affecting the lungs such as pulmonary infarction. Investigations using radioisotopes are of importance in assessing functional abnormalities of the lungs, heart, kidneys and in patients where the flow of cerebrospinal fluid is impaired.

摘要:

An alarm system is described which is aimed at the elderly and disabled at risk when alone in their own homes widely dispersed in the community. It uses a personal radio transmitter operating at 97 kHz and a receiver/telephone autodialler installed in the home of each vulnerable person. A novel unmanned computer-controlled central station is provided to process the calls for help. These are directed firstly to voluntary helpers but finally to an official service only if unanswered. The first helper to answer can handshake the central station to cancel remaining calls. The system offers considerable savings in man power and can cover both town and rural areas effectively. It has undergone a public trial in Harrow and is to be adopted and extended by the local authority. Technical recommendations for future development are made.

摘要:

Living bones have small electrical potentials on their surfaces, the magnitudes of which change only slightly with the reaching of adulthood. When using a limb stresses are put on the bones inside, and these create piezo-electric potentials which may themselves cause bone growth along the lines of stress, hence making the bone stronger. Voltages also appear at fracture sites and may be important in causing the bone to heal its wound. Fractures that have not healed properly can be stimulated into repair by the passage of small electric currents through them. The factors involved in these processes are discussed.

摘要:

A new type of engineering degree course, entitled Engineering Design and Appropriate Technology (EDAT), at the University of Warwick, is described. After explaining the term‘appropriate technology’and its relationship to‘alternative and intermediate technology', the need for a new approach to teaching engineering design is developed. The reasons why present engineering undergraduates receive an education ill-suited to work in appropriate technology are examined. Implicit assumptions underlying all the teaching are claimed to produce graduates unfitted for work in many important fields, such as small firms, job creation, and overseas development. A new set of assumptions to underlie the teaching of appropriate technology are put forward and the resulting implications for the engineering design curriculum are examined. The development of the ED AT course is then described, and finally the course structure and teaching methods are outlined.

摘要:

An iridium-iridium oxide electrode forin vivomonitoring of blood pH changes is described. Because of its small size, sensitivity, flexibility, strength and fast response, this electrode is suitable for acute implantation even in the small vessels of animals such as rats or guinea pigs, allowing continuous pH monitoring anywhere in the central arteries or veins. Excellent noise-free records have been obtained in thein vivoexperiments in animals.

摘要:

Positron-emitting radionuclides are being used more and more in nuclear medicine. This paper describes a high energy collimator suitable for imaging at 511 keV, the energy emitted by these radionuclides, for use with the Baird Corporation's System 77.
