A regional programme to collect plasma for preparation of human immunoglobulin anti-rabies

We identified over 100 recipients of rabies vaccine (human diploid cell vaccine) and recruited them as plasma donors. Some were plasmapheresed at static centres, others by mobile teams. The operation of these teams is described in detail. No plasma was sent to the Fractionation Centre until the date of vaccination had been checked. Assay results showed that the majority of plasma collected between four and 20 weeks after the second dose of vaccine contained 6 or more IU/ml.     

Differential thermal analysis of premix polymer cement materials

In this paper, the use of DTA thermograms, to examine the interaction between premix polymer systems and hydrating cement, are described. The thermograms indicate that the polymerisation method (i.e., thermal or irradiation) has little effect on the nature of the hydration products. It was also observed that polystyrene, polyvinyl acetate, polymethyl methacrylate and polyester-styrene, as premix components, react with the hydrating cement. Polystyrene and polyisoprene have no effect on the calcium hydroxide endotherm while polyacrylonitrile and polymethyl methacrylate have a slight effect. Polyvinyl acetate and polyester-styrene markedly reduce the calcium hydroxide endotherm and reduce the maturity of the paste.     

Personality factors in the selection of civilians for isolated northern stations.

An investigation of personality characteristics associated with favorable adjustment to northern isolated living, and the usefulness of psychological tests in the selection of personnel for northern posting. 197 electronic technicians already screened on other psychological tests completed MMPI, Edwards Personal and Brainard Preference tests, and General Information and Arctic Interest questionnaires prior to 1 year of isolation duty on the mid-Canada Line. Adequacy of work and social adjustment was associated with 11 of 35 test variables and 3 of 26 questionnaire items. The discriminating function of the MMPI was reduced by the use of the K correction. It was suggested that despite the highly select nature of the sample used, the test battery has potential value in the selection of civilians to work in the far north.—(17 ref.)

Psychological aspects of severe burn injuries in children.

Discusses 4 phases of the traumatic process associated with severe burn injuries in children. Predisposing factors (i.e., emotional disturbances) in the preinjury phase are discussed. The acute phase centers on treatment directed toward physiological stabilization. The intermediate phase, in which skin grafts and other painful medical procedures are performed, is characterized by dependency on adults and regression, behavior problems, and such emotional reactions as blaming the parents. Strategies for preparing children for and helping them cope with pain are discussed. The rehabilitative phase often involves difficulties in social readjustment. Strategies for dealing with each phase are presented, most of which focus on prevention efforts. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The performance of heat pumps in service-comparison of a computer model with a real installation

A comparison is made between a computer model which was developed in an earlier paper and experimental results in which a heat pump was used to heat a house during the heating season 1978–1979. The heat pump used was an air-to-water machine, and it is found that the radiator temperature in the experiment varies according to the heat demand of the house because of the effect of thermal inertia of the water and other thermal masses in the heat transfer system. The computer model simulates this effect, using hourly weather data to calculate the heat demand of the house and assuming that the radiators run at the temperature necessary to supply the heat demand during each hour. The model also calculates the coefficient of performance of the heat pump, and hence calculates the running cost in kilowatt-hours for each hour. The calculated running cost is compared with daily readings of kilowatt-hour meters. It is found that the comparison is very accurate during normal operation of the heat pump, with an accuracy of better than 1 per cent over a period of four months of the heating season, although the accuracy is not always quite so good. A comparison is also made between hourly calculated radiator temperatures and continuous recordings of flow and return temperatures. The comparison in this case is satisfactory, but there is a time lag due to the effect of thermal inertia of the building fabric which the computer model is not intended to simulate.
