The effect of chemical structure of polyacrylonitrile -PAN- support membrane on the reverse osmosis performance of thin film composite -TFC- membrane was studied. Accordingly, PAN support membrane was hydrolyzed using alkaline at different contact...

Polyvinylchloride (PVC) membranes were modified

by blending with polyacrylonitrile (PAN) as a second

polymer. The miscibility of PVC/PAN blend was examined

using an incompressible regular solution (CRS) model in no...

QRS detection is the most important step for analyzing electrocardiogram (ECG) signals. In this paper, a new combinatory algorithm based on Pan-Tompkins’ method and wavelet transform is proposed to keep their strengths and avoid the weakpoints...

In this study, polyvinyl chloride (PVC)/ polyacrylonitrile (PAN) blend membrane was modified using sodium hydroxide solution. Fourier Transform Infrared Spectroscopy (FTIR), scanning electron microscopy (SEM), contact angle, porosity and pure water...

hard to employ in locations with no or limited available

data. Evaporation pans are widely used to estimate the

reference ET0, but this method requires reliable estimates

of the pan coefficient (Kp). The objectives of this study...
