With efficient deactivation on glass wool, the Ultra Inert liners with wool provide excellent inertness, homogeneous sample mixing and evaporation, non-volatile residue trapping, and column and detector protection for drugs of abuse screening.
The wool harvesting industry employs workers of varying skill levels that differ in both quality and number of harvested fleeces. As it was unknown how skill affected parameters such as joint posture and loading, the current study comparatively examined 140 wool harvesting workers representing 4 skill levels during wool harvesting competitions. Three-dimensional upper limb postures and peak and...
Here, we monitor the dissolution of several natural protein fibres such as wool, human hair and silk, in various ionic liquids (ILs). The dissolution of protein-based materials using ILs is an emerging area exploring the production of new materials from waste products. Wool is a keratin fibre, which is extensively used in the textiles industry and as a result has considerable amounts of waste p...
8: Bradford and District by A. D. Flather, Hon. Seci^ THE only way, really, is to meet Bradford?with its sharp "a" and "T" in the middle?and see us, the Local Association, there. Bradford feels important but unloved?the centre of the world wool industry, renowned for its dirt, a good place to get out of, in deadly sibling rivalry with its big brother Leeds. As the fabled dog carried its shaggin...
BACKGROUND Despite limited evidence, woollen clothing has traditionally been considered to be an irritant that should be avoided by individuals with atopic dermatitis (AD). Wool fibres come in a range of diameters, and have beneficial thermodynamic and moisture transport properties. OBJECTIVES This study examines the effects of superfine merino wool on symptoms in participants with mild-to-mo...
Wool fibres consist of micro to nano scale protein constituents that could be used for innovative applications. While techniques for extracting these constituents or making wool fibres into organic powders have been developed, effectively dispersing the particles and accurately determining their size has been difficult in practice. In this study, an ultrasonic method was employed to disperse co...
During treatment with oxidizing agents, the disulfide sulfur in wool appears to be changed to higher states of oxidation. The exist ence of oxidation derivatives of the disulfide compounds is indicated by the alkali-solubility determination, the lead acetate test, b y reduction with hydrochloric acid-potassium iodide solutions, and by cystine analyses. The intermediate oxidation derivatives of ...
