High density polyethylene (HDPE) films were produced using cast film extrusion process with different draw ratios, ranging from 16.9 to 148.8. Morphology, crystallinty and orientation state of crystalline and amorphous phases of the cast films were investigated using scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and polarized Fourier transform infrared spectroscopy...

Forward osmosis (FO) has recently drawn attention as a promising membrane based method for seawater and brackish water desalination. In this study, we focus on the use of calciun chloride (CaCl2) and potassium bicarbonate (KHCO3) as inorganic salt draw solution candidates due to their appropriate performance in water flux and reverse salt diffusion as well as reasonable cost. The experiments we...

Founded in 2002, Nineteenth-Century Art Worldwide is a scholarly, refereed e-journal devoted to the study of nineteenth-century painting, sculpture, graphic arts, photography, architecture, and decorative arts across globe.

The purpose of this experiment was to evaluate the usefulness of an image appearance model in predicting the visibility and/or the perceptibility of the noise in various halftone imaging techniques. In this process a paired comparison psychophysical experiment was developed to, first, collect subjective quality data on noise levels for the various halftoning techniques studied. Next an image ap...

One can easily obtain exact closed-form solutions for the compensating variation (and equivalent variation) in the presence of income e¤ects when the policy being evaluated can be described as a change in the state of the world and one is willing to assume the policy change does not change the individual’s epsilon draw. Alternatively, if one assumes the policy changes the epsilon draw, the expe...
