Copolymerization of N-acryloyl-m-aminophenylboronic acid (NAAPBA) with acrylamide (AAm) on the surface of glass plates resulted in the formation of a hydrogel film with porous structure and capable of optical response to the changes in concentration of glucose in the contacting solution. The boronate specific dye, Alizarin Red S (ARS) was incorporated into hydrogel film to increase the sensitivity

We have applied and evaluated system identification methods using both commercial software and dedicated subspace model identification software (MOESP). Results using the different software tools have been similar (but not identical) in accuracy and predictive power, the main differences being the time required for computation and occasional failures of one algorithm in delivery of a stable model.

A spherical reference field is used to construct a digital holographic system with a demonstrated resolution up to 228 line pairs per mm. The reference field originates from a GRIN lens placed 1 mm from the illuminated object. This allows the use of a standard sensor to record the hologram with the required numerical aperture. The image is determined by evaluation of the Rayleigh–Sommerfeld diffra

Kinetic measurements at low temperatures (310-360 K) using gas chromatography (GC) for benzene hydrogenation on Pt(100) and Pt(111) single crystal surfaces have been carried out at Torr pressures. These kinetic measurements demonstrated a linear compensation effect for the production of cyclohexane. A detailed application of the model of selective energy transfer to the experimentally obtained res

One major problem in global governance is the specification of decision-making rules for international and regional organisations to coordinate the states of the world. Various organisations use different decision-making rules, and the properties of these rules may be compared systematically in terms of the power index approach. The power index solution concept of N-person games may be employed to

Molecular interaction between host mucosal surfaces and outer membrane components of microbes is crucial in the infection process. The outer membrane of pathogenic Neisseria contains surface molecules such as pili, PilC, and Opa and a monolayer of lipooligosaccharide (LOS), all of which are involved in the interaction with host cells. Pili mediate the initial attachment to human epithelial cells,

Absorption spectra of a series of cyclic conjugated ketones and thioketones have been computed at the multiconfigurational second-order multistate perturbation level of theory, the CASSCF/MS-CASPT2 method. Excitation energies, transition dipole moments, oscillator strengths, and static dipole moments are reported and discussed for excited states with energies lower than approximate to7-8 eV. The m

We have used the x-ray magnetic circular dichroism technique to characterize ultrathin Co films deposited on flat and vicinal Cu(111) single crystal surfaces. All films were prepared and characterized in situ, in ultrahigh vacuum. Similar to other investigators we report a 40% increase of the ratio m(l)/m(s) (orbital to spin moment) of ultrathin Co on both flat and vicinal Cu(111). In addition, an

The concept of disability-adjusted life years (DALYs) has rapidly gained in popularity in health policy, and considerable research resources are being allocated to this field. Proponents of DALYs suggest that the measure can be used both as a "gross domestic product of health" and to help in setting priorities in health policy. This study investigates the usefulness of DALYs and contends that DALY

Birds harbouring several malarial parasites are common in the wild, and resolving such multiple infections is important for our understanding of host-parasite relationships. We propose a simple and reasonably accurate method for detecting and resolving multiple infections, based on the analysis of parasite cytochrome b DNA sequences: genetically mixed infections are first identified by double nucl

Objective. The incidence of schizophrenia among Surinamese immigrants to the Netherlands is high. The authors tested Odegaard's hypothesis that this phenomenon is explained by selective migration. Method: The authors imagined that migration from Surinam to the Netherlands subsumed the entire population of Surinam and not solely individuals at risk for schizophrenia, They compared the risk of a fir

A simulation model for convective drying of wet porous materials was developed. For the simulation, we measured the moisture diffusivities within them and applied a modified Dubinin-Astakhov equation to the moisture sorption data for a membrane filter. The simulation results not accounting for internal mass transfer resistance were quite different from the experimental ones. The drying characteris

We present a simple dry release technique which uses a thin fluorocarbon film for efficient removal of plastic microdevices from a mould or a handling substrate by reducing the adhesion between the two. This fluorocarbon film is deposited on the substrate in an advanced Si dry etch device utilising the C4F8 passivation plasma. Micromachined polymer chips made of SU-8 are removed from the handling

Identification of incident myocardial infarction (MI) cases in a defined population using hospital discharge data and mortality data in combination has been suggested. This method of case identification was compared to that of use of MI community registers set up in accordance with principles adopted in a World Health Organization collaborative programme. The comparison comprised data for four Swe
