In recent years, several fitting techniques have been presented to reconstruct the parameters of a plate from its Lamb wave dispersion curves. Published studies show that these techniques can yield high accuracy results and have the potential of reconstructing several parameters at once. The precision with which parameters can be reconstructed...

Background. The development of school-based programs for preventing adolescent sexual harassment often lacks an evidence-based approach and use of proper theories. Appropriate stakeholders are often not involved in the development process. To help improve this process, we used the Intervention Mapping framework to retrospectively evaluate the...

A detailed systematic theoretical study of the mechanism of the homogeneous Brønsted-acid catalysis of d-glucose in aqueous solution phase ("acid hydrolysis") is reported. G4MP2 with the SMD solvation model at B3LYP/6-31G(2df,p) are employed to compute the free energies of the molecular and ionic species pertaining to the isomerization,...

Objective: The aim of this paper is to provide a guideline to a universal understanding of the analysis of co-occurrence of risk behaviors. The use of cluster analysis and factor analysis was clarified. Method: A theoretical introduction to cluster analysis and factor analysis and examples from literature were provided. A representative sample ...

For practical chromatographers it is extremely difficult to judge the merits and limitations of new technological developments. On the other hand, it is nearly impossible for those at the forefront of technology to judge the implications of their efforts for all specific applications of chromatography. Both chromatographers and researchers can...

Dutch legislation on the reuse of soil requires a sampling strategy to determine the degree of contamination. This sampling strategy was developed in three stages. Its main aim is to obtain a single analytical result, representative of the true mean concentration of the soil stockpile. The development process started with an investigation into...

Purpose: To investigate the ability to deposit radiofrequency energy centrally in the neck as a function of antenna positions, number of antennas, and operating frequency. Methods and Materials: Power absorption (PA) distributions in a realistic model of the head-and-neck anatomy are calculated in which the head model is irradiated by an array...

Objectives: The present study was designed to investigate the causal relationships between (time- and strain-based) work-home interference and employee health. The effort-recovery theory provided the theoretical basis for this study. Methods: Two-phase longitudinal data (with a 1-ye ar time lag) were gathered from 730 Dutch police officers to...

The economics of small scale gas turbine based cogeneration systems are analyzed on the basis of avoided costs for an electric utility exploiting such systems. This concerns a theoretical study in which the cogeneration system as a means for electricity generation is assumed to supplant the building of new central electricity generating plant....

Driver behaviour will partially be a function of the cognitive schemata by which drivers represent features, functions and operations of traffic system components. This paper uses the Repertory Grid Technique to address the questions: (1) How do drivers internally represent different categories of road? (2) How are those representations mapped...

It is argued that driving cannot simply be considered as a permanent, closed-loop task. Time-to-line-crossing (TLC) is used as a measure to quantify the potential role of visual open-loop and path-error-neglecting strategies. Basically, TLC represents the time available for a driver to neglect path errors until the moment at which any part of...

Progesterone can be determined rapidly and accurately with the method presented, using isotope dilution LC-MS with a moving-belt interface. Deactivation is very useful in that it minimizes belt memory effects and optimizes belt desorption characteristics. Since the moving-belt properties were found to change during time with respect to the...

FIy ash from fluidised bed combustion of bituminous coals contains carbonaceous cenospheres of several forms including thick-walled opaque, transparent with a skeletal structure and 'balloons' without skeletons. The influence on cenosphere formation of particle size, temperature, heating rate, petrographic composition, etc. is reviewed. The...

A study was carried out to establish whether the draft EEC method for determining overall (global) migration of the constituents of plastics-packaging materials into a fatty-food simulant could be applied to samples of commercially available homogeneous plastics materials and whether it would be possible to use extraction with a volatile solvent...

A reliable high-performance liquid chromatographic method is presented for the determination of the urinary free catecholamines noradrenaline, adrenaline and dopamine. Urine is purified on a column of immobilized boric acid. Catecholamines are separated by ion-pair reversed phase high-performance liquid chromatography and detected...

The paper describes the analysis of products of the photochemical degradation of toluene and toluene-14C in smog chamber experiments. Compounds identified included methylglyoxal, possibly the recently postulated butenedial and other carbonyl compounds. The main product of photochemical degradation of methylglyoxal appeared to be acetaldehyde....

A reliable high-performance liquid chromatographic (HPLC) method is developed for the analysis of FAD in whole blood of humans. The method is able to separate FAD, FMN and Rb from each other and from interfering compounds. A reliable and sensitive detection of FAD has been obtained by selecting the optimal pH of the mobile phase and optimal...

The measurement of passive electrical membrane properties in cultured muscle cells is complicated by the fact that the electrotonic length in these cells often exceeds their actual length, leading to serious deviations from the simple infinite cable behaviour. By using very short current pulses for these measurements and integrating the...
