Oil/water emulsions can be produced through phase inversion, by adding water to a reverse water/oil microemulsion. According to small angle neutron scattering experiments and visual observations performed during phase inversion, the stages of this process are as follows: (i) upon water addition, the microemulsion gives way to a highly swollen lamellar phase; (ii) the transient lamellar phase break
A sensitivity study was performed with a nonlinear elastic finite element model for monotonic analyses of wood-framed shear walls. The objective was to provide information about simplifying a model of wood-framed shear walls with no significant loss in accuracy. The simplifications concern features such as slips in joints between frame members, slips in hold-down connections, and bearing between a
Searches for HZ production with the Higgs boson decaying into an invisible final state were performed using the data collected by the DELPHI experiment at centre-of-mass energies between 188 GeV and 209 GeV. Both hadronic and leptonic final states of the Z boson were analysed. In addition to the search for a heavy Higgs boson, a dedicated search for a light Higgs boson down to 40 GeV/c(2) was perf
Fuel ethanol can be produced from lignocellulosic materials to replace gasoline and diesel. A crucial step in the production process is the hydrolysis (saccharification) of the material, which can be achieved with dilute acid at high temperature. Unfortunately, sugar is degraded under these severe conditions, and the sugar yield is generally low. This thesis deals with countercurrent operation, wh
OBJECTIVE: To monitor changes in family physicians' reported practice on hypertension and hypercholesterolaemia. DESIGN: Random samples of physicians were selected for telephone interviews on their practice regarding cut-off levels and pharmacological treatment of hypertension and hypercholesterolaemia, related to a case scenario of a 48-year-old man, in 1989, 1991 and 1993. SETTING: Primary care
The utilisation of biofuels is attracting growing support from the European Union and member states as a strategy to tackle climate change, enhance energy security, and contribute to regional development. This paper describes, compares, and analyses the markets for biofuels in Germany and the UK. The introduction of biofuels for transport in these member states provides contrasting pictures, and t
The CEAP classification for chronic venous disorders (CVD) was developed in 1994 by an international ad hoc committee of the American Venous Forum, endorsed by the Society for Vascular Surgery, and incorporated into "Reporting Standards in Venous Disease" in 1995. Today most published clinical papers on CVD use all or portions of CEAP. Rather than have it stand as a static classification system, a
This paper presents an application of the Hilbert-Huang transform (HHT) and ensemble correlation for detection of the transient evoked otoacoustic emissions (TEOAEs), and high resolution time-frequency mapping. The HHT provides a powerful tool for nonlinear analysis of nonstationary signals such as TEOAEs. Since the HHT itself does not distinguish between signal and noise it was used with ensemble
A novel method for the synthesis of spherical molecularly imprinted polymer (MIP) beads by suspension polymerization in mineral oil is described. The usefulness of the method was demonstrated by the synthesis of a propranolol imprinted MIP library. The composition of the library was generated by statistical experimental design. Multivariate data analysis correlated the screening data, obtained by
In this study the elasto-plastic constitutive equations are reformulated using the assumption of constant strain rate direction within a load increment. This assumption allows the constitutive evolution laws to be rewritten as ordinary differential equations (ODEs). The set of ODEs is reduced using the Krieg and Krieg description of the deviatoric stress space. Although this approach does generall
Living with dementia means struggling to preserve a sense of self, to retain (and reevaluate) one's values in a new situation, and to search for a new way of life. This study explored the meaning of everyday life as expressed by 11 people suffering from dementia. Data were collected through interviews with people in the early stage of a diagnosed dementia disease. The findings indicate that many p
Two different self-adjoint Pauli extensions describing a spin-1/2 two-dimensional quantum system with singular magnetic field are studied. An Aharonov-Casher type formula is proved for the maximal Pauli extension and the possibility of approximation of the two different self-adjoint extensions by operators with regular magnetic fields is investigated.
The aim of this study was to investigate the specificity of the H-3-triolein assay and to investigate the recovery of highly purified pancreatic lipase and pancreatic lipase in the form of pure non-activated pig pancreatic juice. Blood plasma from pigs was analysed for pancreatic lipase activity using the H-3-triolein substrate assay, with a method specific for lipoprotein lipase and with a method
Wireless Personal Area Networks (WPAN) has gained interest in the last few years and several air interfaces have been proposed to cover WPAN applications. A Multi-Carrier Spread Spectrum (MC-SS) air interface specified to achieve 130 Mbps in typical WPAN channels, is presented in this paper. It operates in the 5.2 GHz ISM band and achieves a spectral efficiency of 3.25 b.s-1.Hz-1. Besides the robu
We report on a large scale calculation concerning the 5s(2) S-1 and 5s5p P-1,P-3 levels in Sr-88 I, using multiconfiguration Dirac-Fock methods. Our focus is on the P-3(2) meta-stable level, which has been shown to be extremely useful in atom cooling and trapping experiments. The lifetime for this level from our work (1071 s) agrees very well with a previous theoretical value, but not with the ava
Antibody-based microarrays is a rapidly evolving technology that has gone from the first proof-of-concept studies to more demanding proteome profiling applications, during the last years. Miniaturized microarrays can be printed with large number of antibodies harbouring predetermined specificities, capable of targeting high- as well as low-abundant analytes in complex, nonfractionated proteomes. C
Participation is about finding consensus in diversity and reflects a normative shift towards multiple-use values that recognise that forest management should blend multiple management objectives into a coherent set of practices. A framework to incorporate interest groups' values and needs into functional forest management systems has yet to be institutionalised in contemporary forest policy and ma
Gaussian wave models have been successfully used since the early 1950s to describe the development of random sea waves, particularly as input to dynamic simulation of the safety of ships and offshore structures. A drawback of the Gaussian model is that it produces stochastically symmetric waves, which is an unrealistic feature and can lead to unconservative safety estimates. The Gaussian model des
