A quantitative analysis method for fudosteine in human serum by high-performance liquid chromatography-electrospray ionization tandem mass spectrometry (HPLC-ESI/MS/MS) was established, which shows high sensitivity and selectivity. The mobile phase composition was 75% 20 mM acetic acid and 25% acetonitril, which was pumped at a flow rate of 0.40 mL/min. The overall chromatographic run time was ...

Selectivity estimation is an important task for query optimization. The common data mining techniques are not applicable on large, fast and continuous data streams as they require one pass processing of data. These requirements make Range Query Estimation (RQE) a challenging task. We propose a technique to perform RQE using micro-clustering. The technique maintains cluster statistics in terms o...

The drying of solids in a continuously worked vibrated fluidised bed dryer is studied by simulations. A model considering the drying of a thin layer of particles wetted with a multicomponent mixture is developed. Particles are assumed well mixed in the direction of the airflow and only the longitudinal changes of liquid content, liquid composition and particle temperature are considered. Intera...

In this paper, a color transfer technique based on Adaptive Directional Wavelet Transform with Quincunx Sampling (ADWQS) is proposed to transfer color from a color reference image to a grayscale target image. Due to ADWQS’s directional selectivity and symmetrical characteristic, the proposed scheme yields the best color transfer performance. We search the best matching only in LL subband of lum...

The aim of this project was to remove chloride ions from Eshidiya industrial waste water to be reused in the flotation cells. The industrial wastewater was treated by passing it through ion exchange column. During the experiments, two types of resins were used: anion resin and mixed resin (cation / anion).The selectivity coefficient and the separation factor were calculated in those experiments...

A class of complementary IIR filters is introduced. One of these filters can be realized as a tapped cascaded interconnection of identical allpass subfilters. The complementary filter is then obtained automatically by adding some extra allpass subfilters and a subtractor. The proposed filters are always allpass complementary and, under certain conditions, also magnitude complementary. Further, ...

Vanderploeg, H.A. and Scavia, D., 1979. Calculation and use of selectivity coefficients of feeding: zooplankton grazing. Ecol. Modelling, 7: 135--149. A straightforward method of calculating selectivity coefficients (Wii) of predation from raw data, mortality rates of prey, filtering rates, feeding rates and electivity indices is derived. Results from a comparison of selectivity coefficients fo...

the bottom trawl selectivity parameters (22mm cod-end mesh size) were determined for saurida undosquamis , mullus barbatus , upeneus pori , and pagellus erythrinus along karatas coasts of turkey in northeastern mediterranean waters during fishing season for the year 2002-2003. the lengths at first capture (l 50 ) values for s. undosquamis , m. barbatus , u. pori and p. erythrinus were 12.57, 9....

Habitat suitability (HS) modeling relates a species’ potential presence/absence to a set of environmental variables. because of stochastic or demographic population fluctuations, relating abundance to environment is difficult and generally requires time-series of population-density data. Here, I propose an approach to compute relative capacity of a set of habitat classes. I defined relative cap...

In HPLC, the detector is selected in accordance with the analyte. Many of the detectors used are based on optical absorbance, such as UV-Vis absorbance detectors and photodiode array (PDA) detectors. Absorbance detectors have the following features: The detector sensitivity and selectivity can be adjusted by setting an appropriate detector wavelength. The sensitivity is relatively high (althoug...
