A method for the determination of solanesol in the extracts of tobacco leaves by high performance liquid chromatography has been developed. The column used was Shim-pack CLC-SIL(5 microns, 5 mm i.d. x 150 mm) and the UV detector was set at 215 nm. The eluent was a mixture of n-hexane and isopropyl alcohol (98:2, V/V). As the results showed, the linear range(More)
An algorithm based on the radiance transfer model (RM) and a dynamic learning neural network (NN) for estimating water vapor content from moderate resolution imaging spectrometer (MODIS) 1B data is developed in this paper. The MODTRAN4 is used to simulate the sun-surface-sensor process with different conditions. The dynamic learning neural network is used(More)
A miniaturized chromatographic system with short, narrow-bone columns was used for the measurement of adsorption isotherms of peptides and of nucleic acid constituents on octadecyl-silica by frontal chromatography. The range of mobile phase composition was similar to that used in elution chromatography of the substances investigated. Adsorption isotherms(More)
Classifying individual mosquitoes of the Anopheles quadrimaculatus species complex to species has always been time consuming and complex, involving genetic analysis and profiling. We characterized the wingbeat frequencies of the 3 species of the Anopheles quadrimaculatus complex (An. quadrimaculatus, An. smaragdinus, and An. maverlius) that occur in(More)
In this article, a printed ultra-wideband (UWB) monopole antenna with dual band-notched characteristics of size 26mm×35mm is presented. The prototype consists of pincers-shaped radiation element and corner rounded ground plane. By inserting a pair of flexuous slots on the radiation element and a C-shaped slot on the ground plane, the 3.5/5.5 GHz dual(More)
Hydrogen- (H₂-) induced resistive response of palladium (Pd) coated tungsten oxide (WO₃) films prepared by using supersonic cluster beam deposition (SCBD) was investigated. An SCBD WO₃ film is found to be constructed of WO₃ nanoclusters of diameters of 3-5 nm. The nanoclusters are loosely connected to form a structure of high porosity around 66%. With this(More)
Chromatograms exhibiting unusual elution profiles were obtained in the reversed-phase chromatography of methoxy-substituted hydroquinones with hydro-organic mobile phases. The dependence of the elution profiles on the flow-rate and the mass of injected sample indicated that peaks were caused by the interplay of the chromatographic retention process and the(More)
The retention behavior of methoxy-substituted p-benzoquinones and the corresponding hydroquinones in reversed-phase chromatography was examined on octylsilica and two octadecylsilica stationary phases and with five hydroorganic mobile phases containing acetonitrile, methanol or tetrahydrofuran and additionally in most cases (NH3OH)3PO4 used as a reducing(More)
