TL;DR: There was no difference in the development, duration and titre of the viraemia and neutralising antibody response between the three infected groups of ewes, and virus was isolated from a wide range of tissues and from foetal samples.
40 citations
TL;DR: Histopathological findings covered a wide spectrum of defects that have previously been considered to occur over an extended range of foetal ages, and in the brain, particularly in the cerebrum, cystic areas and malacia, general oedema, subependymal gliosis, perivascular cuffing and mineralised plaques.
34 citations
TL;DR: In this paper, a review of wetting processes and methods for estimating the surface free energy of polymers from contact-angle measurements are discussed, focusing on the relationship between the work of adhesion estimated from surface free energies of solids and the measured adhesive joint strength.
22 citations
TL;DR: Serological surveys revealed that some cattle in northern Australia possessed bluetongue virus (BTV) group-reactive antibodies to BTV20, a new type previously found in Australia, and it was concluded that it was an Australian isolate of the BTV1 serotype.
22 citations
TL;DR: The results of this study suggest that Akabane virus infection of the bull would not affect reproduction.
19 citations
TL;DR: Viraemia was produced in 15 of 16 cows inoculated with Akabane virus into the uterus at oestrus and in 6 of 7 cows after intravenous inoculation, and the corpus luteum was the only tissue to show histopathological changes.

TL;DR: In this article, it was shown that coagulation by indifferent electrolytes, such as sodium sulphate, is the most important destabilizing mechanism, but density is important in determining whether the particles sink of float.
Abstract: When concentrated wool-scouring liquors become destabilized, more suspended particles are recovered in the cream or sludge (or both) than from conventional scouring liquors. The results reported here indicate that coagulation by indifferent electrolytes, such as sodium sulphate, is the most important destabilizing mechanism, but density is important in determining whether the particles sink of float.

TL;DR: In this paper, it was suggested that the thiol groups react with the isocyanate groups of the polyether polyurethane, which would be expected to increase the adhesion between wool and polymer and thereby increase the level of shrink-resistance.
Abstract: The level of shrink-resistance that can be achieved by the application of a polyether polyurethane, Synthappret LKF, to wool fabric can be substantially increased if the wool is reduced with sodium bisulphite or tri-n-butyl phosphine. The effect is reversed by treatments that remove thiol groups. The reductive pretreatment also increases the adhesion between the wool and the polymer. Because the improved shrink-resistance is apparently dependent on the presence of thiol groups in the reduced wool, it is suggested that the thiol groups react with the isocyanate groups of the polymer. Such a reaction would be expected to increase the adhesion between wool and polymer and thereby increase the level of shrink-resistance.

TL;DR: In this paper, the effects of each procedure on the characteristics of the raw wool and the processing of the wool are discussed, as well as the effect of the clip-preparation procedures on the quality of the resulting yarn.
Abstract: An investigation is described in which wool from a burry topmaking clip was formed into batches representative of both conventional and alternative clip-preparation procedures, and the batches were processed into worsted tops. The preparation procedures investigated ranged from conventional skirting and classing to the retention of all the wool in one line. The effects of each procedure on the characteristics of the raw wool and the processing of the wool are discussed.
TL;DR: In this article, an investigation of the fisherman's knot and its performance in torque-unbalanced weaving yarns is reported, and the physical characteristics of the structures are explored, and dramatic differences in their rates of slippage are shown to exist.
Abstract: An investigation of the fisherman's knot and its performance in torque-unbalanced weaving yarns is reported. The term ‘fisherman's knot’ is shown to encompass three distinct knot structures. The physical characteristics of the structures are explored, and dramatic differences in their rates of slippage are shown to exist. Slippage is shown to occur predominantly via a change in knot structure rather than by yarn simply pulling through the structure.
TL;DR: In this article, the molecular weight distribution at different stages in the preparation of polycarbamoyl sulphonates (PCSs) was examined by gel permeation chromatography (GPC) using detection methods appropriate to either the total polymer concentration or the number of terminal groups.

TL;DR: This is an interim report on screening for learning problems in the first year at school and forms part of a prospective study of convulsions, epilepsy and learning disorders which commenced in 1970.
Abstract: . This is an interim report on screening for learning problems in the first year at school. It forms part of a prospective study of convulsions, epilepsy and learning disorders which commenced in 1970.
Poor correlation between teacher and parent opinion as to school readiness, activity, clumsiness and inco-ordination is shown. For example, in only 2% did both parent and teacher consider a child over-active.
The problems encountered by teachers suggests a need for a wider variety of learning experience for children starting school than presently offered in Victoria.
TL;DR: It has not been shown that any occupationally attributable respiratory morbidity is occurring in the Brisbane waterside workers studied by Dr Mitchell and his colleagues, and the comparison is inherently unjustified and, in view of Fournier-Massey & Becklake's findings, manifestly misleading.
Abstract: 20"10 of controls. He notes the prevalence recorded in the case of Quebec asbestos workers was 2% and in Devonport Dockyard workers 10%. The reference he cites states that the Quebec films were read by six readers and the Devonport films by four. It is open to doubt that had the Brisbane films been read by some such number of readers, the proportion reported as showing fine irregular opacities would have been as high as 47"10. Fournier-Massey & Becklakestudied the lung function patterns of Quebec asbestos miners and miners. Among 106 non-smokers they found that 4.1% showed a restrictive pattern and 0.6%an obstructive pattern ~ among 890smokers 12.2%showed a restrictive pattern and 14.5% an obstructive one. In the case of neither pattern did asbestos dust exposure, using a measure much more precise that Dr Mitchell's DEW, appear to influence the outcome, although smoking habit certainly did. In this context Weiss et al found that smoking habit was much more important in determining the prevalence of pleural plaques than was asbestos exposure. 3 Dr Mitchell accounted for 41% cf the variance of FVe, a measure of restriction to which smoking habit contributed 6% and DEW only 2"10. In view of this and of the earlier Quebec findings ~ is unexpected that be should find decrement of FVC to be related to DEW, but he goes on to compare his waterside workers, lSO"Io of whom were cigarette smokers, with a group of controls of whom none was a smoker. On the basis of this comparison he concludes: ""FVC decreases by 65% over and above the age-related reduction". This is an alarming conclusion. The comparison is inherently unjustified and, in view of Fournier-Massey & Becklake's findings, manifestly misleading. It has not been shown that any occupationally attributable respiratory morbidity is occurring in the Brisbane waterside workers studied by Dr Mitchell and his colleagues. It need hardly be added that it has not been shown that asbestos is the cause of what has not been shown to be happening.
