The effect of dry material, glycerol and ratio of water to seed in alyssum homalocarpum films on their thickness, transparency, moisture content, tensile strength, elongation and water vapor permeability was investigated using mixture response surface methods. Dry material and glycerol were important factors influencing tensile strength, elongation and water vapor permeability. Ratio of water t...

Inflow control devices (ICD), which prevent water breakthrough by controlling the inflow profile of a well, have been used successfully in many oilfields. This paper will introduce a new discovery and an unsuccessful example. Moreover, this paper investigates meticulously and thoroughly to find the application conditions of the new discovery. Based on permeability rush coefficient and permeabil...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...
it was difficult to obtain directly in a single experiment films of exactly 0.1-mm. thickness, several films were selected so that the thickness of each film might be distributed in a range from 0.05 to 0.4 mm. and the respective water vapor permeability was measured at various humidity conditions. Plotting the relationship between permeation resistance (l/Q) and film thickness (I) gave a strai...

In this study, biodegradable kefiran-chitosan-nanocellulose blend films were developed and their physical, mechanical, barrier, thermal and structural properties determined. Results showed that adding nanocellulose had not any significant effect on the thickness, moisture content and water solubility. Also, water vapor permeability, tensile strength and lightness increased and the elongation at...
in this thesis, barium ferrite nano particles were prepared by sol-gel method. their structural and magnetic properties of samples have been investigated using thermo gravimetric analysis (tg-dta), x-ray powder diffractometer (xrd), fourier transform infrared (ftir), scanning electron microscopy (sem), field emission scanning electron microscopy (fesem), ac susceptometer, vibrating sample magne...
