Clothing Colour Preferences in A Hospital Environment in Hong Kong:Part Ⅱ-Paediatric Nurses’Preferences of Colour on Their Uniform

The present study investigated nurses'colour prefer-ences on their uniform in paediatric wards.Results ofthe study provided guidelines for the selecting of ap-propriate colours for nurses'uniforms for paediatricwards,and the comparison of nurses'preferences ofcolours on their uniform and child patients'colourpreferences of nurses'uniform was drawn.     

Tensile property of Pneumatic spliced Short-staple Ring Spun Yarns

The tensile property of the spliced yarn splice under different splicing conditions has been investigated. The retained spliced strength of the splice spliced under different splicing conditions was obtained as the indicator for the performance of the splicer under that particular splicing condition. The results showed that, the length of the yarn tails and the yarn linear density are the parameters that has the most important effect to the tensile property of the spliced yarn.     

The ovicidal activity ofcis-dehydromatricaria ester: time-dependance of its enhancement by UV light

Summary Freshly laid eggs ofDrosophila melanogaster were treated with the polyacetylenic compoundcis-dehydromatricaria ester. The toxicity of the chemical was enhanced by treatments with long-wavelength ultraviolet light, and the maximum effect was observed when the UV irradiation was performed 4–5 h after the initial contact of the eggs with the chemical.We are grateful to Professor E. Spiess for advice and assistance, and to the National Institutes of Health (GM 24144) for financial support.
