1. Experimental and Clinical Studies on Contact Allergy to Diphenylmethane-4,4′-diisocyanate and Related Substances
Abstract : The exposure to isocyanates is more of an occupational problem than a consumer problem. The main route of exposure is assumed to be through inhalation. Isocyanates that have high vapor pressure, such as TDI, can be airborne at room temperature. Other isocyanates such as MDI are volatile only when heated. READ MORE

3. The Complex World of Superstrings : On Semichiral Sigma Models and N=(4,4) Supersymmetry
Abstract : Non-linear sigma models with extended supersymmetry have constrained target space geometries, and can serve as effective tools for investigating and constructing new geometries. Analyzing the geometrical and topological properties of sigma models is necessary to understand the underlying structures of string theory. READ MORE

4. Transformation of iron constituents during early diagenesis : in situ studies of a Baltic Sea sediment-water interface
Abstract : The aim of the present study was to elucidate the mechanisms and kinetics of the transformation of iron constituents at the sediment-water interface and their interaction with other element cycles during early diagenesis, with emphasis on their relations with oxygen, phosphorus and sulphur. The investigation was carried out in situ at 10 m water depth on a nearshore Baltic Sea soft bottom sediment. READ MORE
