  1. 1. Contact allergy to formaldehyde. Diagnosis and clinical relevance

    Författare :Inese Dubnika Hauksson; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Allergic contact dermatitis; preservatives; formaldehyde; formaldehyde releasers; patch testing; repeated open application test; baseline series;

    Sammanfattning : Preservatives are biologically active substances mainly used in water-based products to prevent the growth of microorganisms. Most people are exposed to them on a daily basis. Formaldehyde is one of the oldest and most commonly used preservatives. However, it is a well-known contact sensitiser in dermatitis patients. LÄS MER

  2. 2. Contact Allergy to Acrylates

    Författare :Anthony Goon; Yrkes- och miljödermatologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; volatility; stability; screening; allergic contact dermatitis; Acrylates; baseline series; contact allergy; dental; gel permeation chromatography; high performance liquid chromatography; industrial; patch testing; methacrylates;

    Sammanfattning : Acrylate contact allergy has been frequently reported since the 1970s, with hundreds of articles published in dermatology journals so far. The purpose of this thesis was to investigate the frequency of contact allergy to acrylates / methacrylates in patients with exposure to industrial, dental and nail uses of these substances. LÄS MER

  3. 3. Analysis of Temporal and Spatial Variations in Atmospheric Water Vapor Using Microwave Radiometry

    Författare :Per O. J. Jarlemark; Chalmers tekniska högskola; []

    Sammanfattning : The amount of atmospheric water vapor is highly variable in both time and space. In this thesis some aspects of the variations in the atmospheric water vapor are treated. LÄS MER

  4. 4. Studies of Atmospheric Water Vapor Using the Global Positioning System

    Författare :Ragne Emardson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; troposphere; microwave radiometry; climatology; radiosondes; atmospheric water vapor; Global Positioning System; time series analysis; VLBI; space geodesy; GPS; Very Long Baseline Interferometry; meteorology; radio wave propagation; Kalman filtering;

    Sammanfattning : Atmospheric water vapor is of fundamental interest in the Global Positioning System (GPS) and Very Long Baseline Interferometry (VLBI) techniques. These techniques are based on the timing of radio waves propagating through the atmosphere. LÄS MER
