    Aquagenic pruritus associated with the idiopathic hypereosinophilic syndrome (1990)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: Patients with the idiopathic hypereosinophilic syndrome (HES) may develop associated skin disorders. We describe a patient who had xerosis since birth, but who first developed symptoms of aquagenic pruritus soon after he presented with HES. Photochemotherapy with psoralen and UVA treatment reduced his peripheral blood eosinophil count. The good response to treatment suggests that there was a close relationship between the dermatosis and the blood disorder.

    A GRID GENERATION TECHNIQUE FOR NUMERICAL MODELLING HEAT and MOISTURE MOVEMENT IN PEAKED BULKS of GRAIN (1993)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: This paper describes a numerical solution procedure to study heat and moisture transfer processes by two-dimensional natural convection phenomena in grain stores with arbitrary geometries. This enables grain storage technologists to investigate the design and performance of grain stores in which the grain surface is peaked, as in bunker storage, for example. Momentum transfer is described by an elliptic partial differential equation, which governs the behavior of the stream function. Using an algebraic grid generation technique, the governing equations are transformed into a body-fitted rectangular coordinate system that allows coincidence of all boundary lines with a coordinate line. Numerical solutions of the resulting equations are obtained using an alternating direction implicit method. Results from numerical experiments on a peaked bulk of stored grain retained between two vertical walls are obtained that show the magnitude and directions of convection currents and contours of temperature, moisture, dry matter loss and chemical pesticide concentrations.

    Mutational analysis of glutamine synthetase response to the ammonium analogue ethylene diamine in the cyanobacterium Nostoc muscorum (1992)

    Notes: Abstract Methionine sulphoximine resistant (Msxr) glutamine synthetase (GS) strain and ethylene diamine resistant (Eda1) GS strains of Nostoc muscorum did not show a cross-resistance relationship. The parents, Msxr-GS and Het Nif strains mutated spontaneously to the Eda1 phenotype, and the results of spontaneous mutation frequency suggested a role of the gln A allele in control of its mutation frequency of Edar-GS phenotype. Edar clones comprised two functionally distinct classes, the Edars class having severely defective GS activity and excreting ammonia and the Edart class having a slightly defective GS activity and assimilating EDA like a fixed nitrogen source.

    A class of glyphosate-selected mutants of the cyanobacterium Nostoc muscorum showing loss of ammonium transport activity (Amt−), heterocyst formation (Het−) and nitrogenase activity (Nif−) (1989)

    Notes: Abstract Glyphosate was considerably more growth inhibitory to N2-assimilating than to ammonium-assimilating cultures of N. muscorum. The herbicide, while inhibiting nitrogenase activity and ammonium [14C]-methylammonium) uptake activity caused significant increase in the biosynthetic activity of in vivo glutamine synthetase (GS) in N2-assimilating or ammonium-assimilating cultures and nearly 50% derepression of heterocyst formation and nitrogenase activity in ammonium assimilating cultures. The differential toxicity of the herbicide to N2-fixing cultures led us to use this herbicide as selective agent to isolate a class of mutant clones on ammonium-supplemented medium which lacked heterocyst differentiation (Het−), nitrogenase activity (Nif−) and ammonium [14C]-methylammonium) uptake activity (Amt−). It is concluded that heterocyst differentiation, nitrogenase activity and ammonium uptake activity are all under the regulatory control of common genetic determinants in the cyanobacterium.

    Prediction of Thermal Conductivity of Fruit Juices by a Thermal Resistance Model (1989)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 54 (1989), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: A model for prediction of thermal conductivity of fruit juices was developed. The model was based on the concept of thermal resistances in parallel and compared with other models and experimental values. Effect of temperature and solid concentration on thermal conductivity was discussed. Extension of the model to predict thermal conductivity of fruit juices below the freezing temperature was briefly discussed. The model gave error of less than 10% from the experimental values for juices for which such values were available.

    Corrosion of stainless steels in chlorine dioxide solution (2002)
    Bradford : Emerald
    Anti-corrosion 49 (2002), S. 417-425

    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Until recently, chlorine used to be an important chemical in bleaching process in paper industry, but as a result of environmental concerns, it is being replaced by chlorine dioxide. However, chlorine dioxide is more corrosive in certain conditions. Plant personnel, therefore need to better understand the reactions taking place in the changed media and search for more resistant materials. It is with this in mind that the present work was undertaken. The paper reports the electrochemical polarisation measurements performed on stainless steels 316L, 317L, 2205 and 254SMO in chlorine dioxide solutions to observe localised corrosion. The results have been analysed with reference to Pourbaix diagrams, taking into account the various chemical species present in the bleach solutions. Conclusions drawn from electrochemical tests have been compared with those from long-term laboratory and plant tests. Materials options are proposed on the optimal choice of materials for bleach plants, in a context of probable corrosion performance, capital cost and mechanical strength.

    Edge potential effect on the operation of short-channel devices (2003)
    Bingley : Emerald

    Notes: We have solved the two-dimensional Poisson's equation for short-channel device under the assumption that even in the absence of drain-to-source voltage (VDS), a potential occurs at the edges (source/drain) due to discontinuity at the semiconductor - channel interface in addition to built-in-potential. We have developed some new relations governing the operation of short-channel devices. Analysis of relation shows that in the absence of drain-to-source voltage (or for very low drain-to-source voltage), the position of minimum potential will occur exactly at the middle of the channel. The short-channel effect is not only observed due to applied drain-to-source voltage, but also due to edge potential when no bias is applied between drain and source.
