Cotton fiber elongation (extensibility, elongation at breaking load) is one of the least utilized measurements from the high volume instrument (HVI). This may be due, in part, to the large standard deviation of this HVI measurement. In addition, the correlation of fiber elongation with yarn elongation is not as high as the physical theory of yarn strength suggests. Thus, an improved method for ...

This study was conducted to assess the effects of irrigation and plant growth promoting bactera on seed yield and qualitative characteristics of Black cumin (Nigella sativa L.) at the Experimental Station of the Research Institute of Forest and Rangeland, Damavan region, Iran. A split-plot experimental design, based on Randomized Complete Block Design (RCBD) with three replications, was used. I...

Abstract This work explores the scope and limitations of enhancing poor mechanical properties diblock copolymers by blending with tapered multiblock styrene (S) isoprene (I), P(I‐ co ‐S) n . Blending different ( = 1; M 80 240 kg mol −1 , 50 wt% polyisoprene (PI) units, lamellar morphologies) affords brittle materials low elongation at break. An increasing degree phase separation from (i) miscib...

This study investigates the effects of fabric properties and ultrasonic welding on performance surgical gowns. For this purpose, eight spunlace fabrics with different structural were provided. First, fabrics’ thickness, tensile strength, elongation at break, air permeability, drape behavior, surface friction investigated. Then sewn sewing machine. Afterward, seam permeability behavior tested. T...

Rice husk ash (RHA) is an agrowaste byproduct resulting from the incineration of rice husks for power production; white RHA is 90 wt% or more silica, which makes it a potentially sustainable and inexpensive substitute for commercial (less “green”) silica filler. Past research on polypropylene (PP)-RHA hybrids made by melt processing has yielded modest increments in Young’s modulus, reduced yiel...

Although they have potential environmental pollution issues, soft contact lenses are value-added biodevices for medical use. Thus, it is important to reconsider starting materials and production methods achieve sustainable development. In this study, hydrogels composed of hydroxypropyl cellulose (HPC) as an environmentally friendly material were produced by radiation investigated use in disposa...

A comprehensive rheological characterization of highly concentrated suspensions or pastes is mandatory for a targeted product development meeting the manifold requirements during processing and application of such complex fluids. In this investigation, measuring protocols for a conclusive assessment of different process relevant rheological parameters have been evaluated. This includes the dete...

It has been suggested that existing estimates of the long-run impact of a surprise move in income may have a substantial upward bias due to the presence of a trend break in 1970s (1350s) and 1980s (1360s) gross domestic product (contained oil) data of Iran. This article shows that the statistical evidence does not warrant abandoning the no-trend-break null hypothesis at the 5% significance leve...
