  1. 1. Contact allergy to textile dyes. Clinical and experimental studies on disperse azo dyes

    University dissertation from Occupational and Environmental Dermatology Unit

    Author : Laura Malinauskiene; Lunds universitet.; Lund University.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disperse Orange 1; Disperse Yellow 3; metabolites; azo reduction; p-aminodiphenylamine; 4-nitroaniline; 2-amino-p-cresol; 4-aminoacetanilide; TLC; HPLC; guinea pig maximisation test.;

    Abstract : Disperse dyes are the most common allergens among textile dyes. It is not known whether the purified dyes, impurities in the commercial dyes, or metabolites are the actual sensitisers. Moreover, it is not known whether those disperse dyes that are now present in test series are actually used in textile dyeing today. READ MORE

  2. 2. Contact Allergy to Textile Dyes - Clinical and Chemical Studies on Disperse Dyes

    University dissertation from Department of Occupational and Environmental Medicine, Lund University

    Author : Kristina Morgardt-Ryberg; Lunds universitet.; Lund University.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Disperse Blue 106; contact allergy; Disperse Orange 3; disperse dyes; Disperse Blue 124; TLC; textile-related skin problems; textile dye mix; PPD; HPLC; impurities;

    Abstract : Disperse dyes are common sensitizers among textile dyes. Contact allergy to disperse dyes has been documented in studies carried out in southern Europe, however, corresponding studies have not been performed in the Scandinavian countries. READ MORE

  3. 3. A study of heat transfer from cylinders in turbulent flows by using thermochromic liquid crystals

    University dissertation from Stockholm : Mekanik

    Author : Roland Wiberg; KTH.; [2004]
    Keywords : Fluid mechanics; convection heat transfer;

    Abstract : In gas quenching, metal parts are rapidly cooled from hightemperatures, and the convection heat transfer coefficientdistributions are of importance for the hardness and thedistortion (the shape nonuniformities) of the quenched parts.Thermochromic liquid crystals (TLC) and a thin foil techniques,were investi- gated and used for studies of a circular cylinderin axial flows, affected and not affected by upstream owmodifying inserts.

  5. 5. In situ remediation of contaminated sediments using thin-layer capping : effectiveness in contaminant retention and ecological implications

    University dissertation from Stockholm : Stockholms universitets förlag

    Author : Göran Samuelsson; Stockholms universitet.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thin layer capping; sediment remediation; activated carbon; contaminated sediment; benthic community; Systems Ecology; systemekologi;

    Abstract : Hydrophobic organic contaminants (HOCs) often reside in sediment sorbed to particles, most tightly to particles with high content of organic carbon. If persistent, such pollutants can accumulate in the sediment for many years and constitute a contamination risk for sediment-living organisms and organisms at higher trophic levels, including humans.
