Three products hyrdrocyclone screen (TPHS) has been proposed for particle separation based on size. In TPHS, a cylindrical was embedded in conventional hydrocyclone (CH) to combine the centrifugal classification and screening The industrial application of TPHS indicates its better device performance than CH. Although, earlier studies reveal some common understanding information absent air colum...

The reduction of Cr(VI) by use of a cheap and locally available industrial waste, scrap iron, was investigated in continuous system. The experimental results showed that, at the beginning of the column experiment, Cr(VI) was not detected in column effluent, which means that it was completely reduced. The greater the pH of column influent, the lower the time period before the breakthrough of hex...

diastole (A1-A4) and in systole (B1-B4). All images were acquired from a single healthy subject scanned four separate times. Figure 1: Method for KWIC reconstruction of T1ρ data. Undersampled radial images were acquired during which the spin lock duration (TSL) was varied in each (Columns 1 and 2). During KWIC reconstruction, high spatial frequency components with a minimum kspace radius kmin w...

The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally required a lot of parameters related to tray or pack geometry. On an industrial viewpoint, such a complexity penalizes the achievement of a fa...

Thyroid peroxidase (TPO) was purified from each thyroid of 10 patients (experiment 1) and 4 patients (experiment 2) with toxic diffuse goiter by a simplified method with monoclonal anti-TPO antibody-assisted immunoaffinity column chromatography. The final preparations were used to measure the heme concentration based on the cyanide difference spectrum, and to determine the Km and kcdt values fr...

In a multi-step outflow experiment we found that a weak heterogeneity within a sand column prevents the estimated effective hydraulic parameters from being unique. We compared vertical water content profiles calculated from these parameters with profiles measured by x-ray attenuation. A layered material model based on x-ray data was able to reproduce the outflow curve and also the water content...

New UPLC method was developed for determination of sitagliptin and metformin using Symmetry C18 column (100 mm × 2.1 mm, 2.2 μm) and isocratic elution (methanol 20%), pH (3.5) as a mobile phase. The ultraviolet detector was operated at 220 nm and the column temperature was 50°C. Linearity parameters were acceptable over the concentration ranges of 2-12 μgml(-1) and 5-35 μgml(-1) for sitagliptin...

—Tables offer an often used way to represent information for the human reader. But as long as those tables are not annotated with semantic information they are meaningless to machines. In this work a methodology is proposed to annotate the headers of table columns with semantic types by creating a ranking of possible column headers based on the column cells. In the performed experiments on 10 i...

Latin hypercube designs (LHDs), widely used for computer experiments, are a very large class of designs with desirable properties. Recently, a number of methods have been proposed to construct orthogonal LHDs. In this paper, we introduce an approach to constructing 2-order orthogonal designs. The methods are simple and easy to implement. Using orthogonal designs, we propose some methods for con...

This paper gives a general method for constructing quasi-Latin square, quasi-Latin 12 rectangle and extended quasi-Latin rectangle designs for symmetric factorial experiments. Two 13 further methods are given for parameter values satisfying certain conditions. Designs are 14 constructed for a range of numbers of rows and columns so that the different construction 15 techniques are illustrated. ...
