This paper investigates the performance of a column classification system developed at the Katholieke Universiteit Leuven applied to pharmaceutical chromatographic analyses. The liquid chromatography assay of lamotrigine and related compounds was carried out according to the method prescribed in the European Pharmacopoeia monograph, using 28 brands of stationary phases. A ranking was built base...

This paper describes an innovative design of a wireless, passive LC sensor and its application for monitoring of water content in building materials. The sensor was embedded in test material samples so that the internal water content of the samples could be measured with an antenna by tracking the changes in the sensor's resonant frequency. Since the dielectric constant of water was much higher...

A novel design of a MEMS torsional resonant magnetometer based on Lorentz force is presented and fabricated. The magnetometer consists of a silicon resonator, torsional beam, excitation coil, capacitance plates and glass substrate. Working in a resonant condition, the sensor's vibration amplitude is converted into the sensing capacitance change, which reflects the outside magnetic flux-density....

A fan effect experiment where participants perform recall and recognition tasks on a study set of sentences with three content words was conducted. The aggregate results confirm a fan effect (Anderson, 1974). A model of the recall and recognition tasks was created using Dynamically Structured Holographic memory (DSHM). A comparison to the human data is presented. A discussion of the current res...

Resonant Auger electron spectra were measured for several condensed molecules …Si…CH3†3Cl, SiCl4, PCl3, C3H7SH and CCl4† around Si-, P-, S-, and Cl-1s edges. It was commonly found that the most frequent decay channel after the excitation was a KL2; 3L2; 3 transition. As predicted by a resonant inelastic scattering theory, the phenomenon known as the Auger resonant Raman effect was observed in t...

The platelet retention test provides a measure of the number of platelets retained in a column of glass beads and is one of the few in vitro platelet function tests that is abnormal in von Willebrand’s disease (vWd). In a two-stage test, 1 mL of blood (designated A) was passed through the column, followed by 5 mL of isotonic saline and then 5 mL of blood (B) in which platelet retention was meas...

Both spin and orbital angular momentum can be exchanged between a rotating wave magnetized plasma. Through resonances the of coupled to both cyclotron rotation drift particles. It is, however, shown that Landau resonance conditions which classically describe resonant energy–momentum exchange waves particles are no longer valid in plasma column. In this case new condition involves matching frequ...
