One-particle resonant levels in a deformed potential

(S)olving the Schrodinger equation in coordinate space with the appropriate asymptotic boundary conditions, neutron one-particle resonant levels in Y-20-deformed Woods-Saxon potentials are studied. These resonance levels are the natural extension of one-particle bound levels to the continuum and are defined in terms of eigenphase. For one-particle bound levels with Omega(pi)not equal 1/2(+) the co

A model for heat and mass transfer in timber structures during fire: a theoretical, numerical and experimental study

A model has been formulated for the pyrolysis of wood. This model includes heat and mass transfer. Heat transfer in the material is assumed to take place by thermal conduction and convection. Mass transfer of volatile pyrolysis products and water vapour occurs under the influlence of gradients in to tal pressure. Pyrolysis is assumed to conform to an Arrheniusfunction, and vaporization occurs at a

A detailed chemical reaction mechanism for the oxidation of hydrocarbons and its application to the analysis of benzene formation in fuel-rich premixed laminar acetylene and propene flames

On the basis of existing detailed kinetic schemes a general and consistent mechanism of the oxidation of hydrocarbons and the formation of higher hydrocarbons was compiled for computational studies covering the characteristic properties of a wide range of combustion processes. Computed ignition delay times of hydrocarbon -oxygen mixtures (CH4-, C2H6-, C3H8-, n-C4H10-, CH4 + C2H6-, C2H4, C3H6-O-2)

The gap between guidelines and reality: Type 2 diabetes in a national diabetes register 1996-2003

Guidelines for the treatment of risk factors in diabetes care have been updated recently, due to indisputable results from clinical end-point trials. This study evaluates risk factor control compared with current national and international targets during the period 1996-2003 in Type 2 diabetes (DM2). Patients were registered in primary-care and hospital outpatient clinics using computer software,

Genetic engineering and the moral status of non-human species

Genetic modification leads to several important moral issues. Up until now they have mainly been discussed from the viewpoint that only individual living beings, above all animals, are morally considerable. The standpoint that also collective entities such as species belong to the moral sphere have seldom been taken into account in a more thorough way, although it is advocated by several important

Synthesis of dicyanopyridines

Synthesis of the title compounds in four steps using inexpensive collidine and lutidine as starting materials is described.

Conference summary

In this summary I briefly discuss some of the many interesting talks presented at this symposium.

Utilisation of antibiotics in young children: opposite relationships to adult educational levels in Danish and Swedish counties.

Background. Antibiotic utilisation varies profoundly among and within countries, and the extent of antibiotic utilisation correlates with the frequency of bacterial resistance, particularly among children. Hence, it is important to assess which factors may influence prescribing. In addition to variations in morbidity, health-care organisation, drug regulatory and supply systems, prescriber's attit

A flow immunoassay for alkylphenol ethoxylate surfactants and their metabolites - questions associated with cross-reactivity, matrix effects, and validation by chromatographic techniques

This paper describes the application and evaluation of a competitive enzyme flow injection immunoassay (EFIIA) for screening of alkylphenol ethoxylate (APEO) surfactants in different water samples based on a generic immunoassay system previously developed ( see E. Burestedt, C Nistor, U. Schagerlof and J. Emneus, Anal. Chem., 2000, 72, 4171 - 4177). The detection limits for octylphenol ethoxylates
