    Notes: A one-dimensional finite element model, associated with a computer code, has been developed to simulate the thermal response of a decomposing glass-fibre reinforced composite exposed to a fire environment. The numerical model uses a first-order Arrhenius equation and includes: transient heat conduction; gas mass flux and internal heat convection of decomposition gases; density loss and Arrhenius decomposition of active material into decomposition gases and residual char; and endothermicity of the decomposition process. An empirical formula, obtained from furnace tests, has been applied to the model as the incident heat flux boundary condition at the heated surface. Presents results for the standard thickness of polyester-based GRP laminate, 10.9mm, for offshore structures. The predicted temperature profiles are in good agreement with experimental temperatures obtained from furnace tests. This model is able to simulate fire performance characteristics for a large range of typical offshore components with different constructions and materials. It will enable accurate predictions of the life-time of offshore components in severe offshore hydrocarbon fires.

    Notes: The aerobic bacterial flora of 20 patients with atopic dermatitis and 19 control subjects was extensively sampled using the Williamson and Kligman scrub technique and a contact-plate method (cysteine lactose electrolyte deficient media). Comparison of the two quantitative techniques showed that the contact plate is a reliable and convenient alternative to the scrub technique for the quantification of Staphylococcus aureus, micrococci and coagulase negative staphylococci. Quantification of bacterial flora using both techniques showed high rates of colonization by S. aureus on both involved and clinically normal skin of patients with atopic dermatitis. A linear increase in S. aureus counts with increasing severity of dermatitis was found. In contrast, diphtheroids showed a trend of decreasing isolation rates and counts as the severity of the dermatitis increased. Isolation rates and absolute counts for micrococci/coagulase negative cocci were unaffected by the severity of the dermatitis.

    Notes: Abstract. Exchange effects in rearrangement reactions are studied in the framework of a general algebraic theory of identical-particle scattering. An algebraic definition of reaction mechanisms proposed previously is used to distinguish the contributions to scattering amplitudes made by different exchange processes. Previous statements concerning the number of possible exchange mechanisms and their relative weight factors are rigorously proved. The results of this paper differ from those obtained in previous studies, as here identical clusters of particles are also treated as indistinguishable.
