the wheat straw as abundant lignocellulosic resource was successfully undergone in a benzylation reaction and plasticized with different contents (2.5, 3, 5 and 7 wt. %) of glycerol and stearic acid.the effect of type and concentration of plasticizers on the mechanical, thermomechanical, morphological and water absorption properties of benzylated wheat straw (bws) was investigated by tensile, d...

The effects of changes in the conformational state of DNA on the single-strand and double-strand breakage activity of two antitumor antibiotics, bleomycin (BLM) A2 and phleomycin Di, have been studied by the gel electrophoretic analysis of the drugdegraded PM2 phage superhelical DNA pretreated with an inter calating agent, ethidium bromide (EB). Both the single-strand and double-strand breakage...

In a nuclear power plant environment, low-voltage cables experience different stresses during their service life which challenge integrity. A non-destructive and reliable condition monitoring technique is desired to determine the state of these for extension plants. Hence, in this research work, an EPR/CSPE-based cable was exposed ?-rays five absorbed doses. The overall behavior under stress ch...

Abstract Background The strength of cotton fiber has been extensively studied and significantly improved through selective breeding, but elongation largely ignored, even though contributes to determining the energy needed break fibers. Recent developments calibrate high volume instrument (HVI) for renewed interest in elongation. However, it is not understood how best utilize yet another propert...

in this study the feasibility of using salep as a new film-forming material was studied. the mechanical properties, water vapor permeability and thickness of salep films incorporated with glycerol were determined. increasing the content of dry material of salep from 1% to 3%(w/v) increased values for tensile strength and elongation at break from 16.16% and 18.85 mpa to 70.15% and 24.50 mpa resp...

The aims of this study were the extraction of hemicellulose from wheat straw (WS) and its utilization in the reinforcement of a κ-carrageenan/locust bean gum (κ-car/LBG) polymeric blend films (PBFs). WS hemicellulose extraction was performed under autohydrolysis process and hemicellulose extracted (HE) under optimum condition was used in PBFs. PBFs were prepared varying different proportions of...

Administered by an oral route, Furosemide (FUR), a diuretic used in several edematous states and hypertension, presents bioavailability problems, reported as a consequence of an erratic gastrointestinal absorption due to various existing polymorphic forms and low and pH-dependent solubility. A mucoadhesive sublingual fast-dissolving FUR based film has been developed and evaluated in order to op...

Regarding the importance of ring spinning method among spinning systems, great potentials exist for research about on the improvement of the quality and properties of ring spun yarn. This study aims to improve yarn quality by changing the shape and dimensions of spinning triangle through forming a groove in the middle zone of the front darfting roller with a curvature of 5 to 7 mm. For the to...

Biodegradable starch-based chitosan reinforced composite polymeric films were prepared by casting. The chitosan content in the films was varied from 20% to 80% (w/w). Tensile strength (TS) was improved significantly with the addition of chitosan but elongation at break (EB %) of the composites decreased. Tensile strength of the composites raised more with the addition of the acacia catechu cont...

This study was to develop novel soy protein isolate-based films for packaging using halloysite nanotubes (HNTs), poly-vinyl alcohol (PVA), and 1,2,3-propanetriol-diglycidyl-ether (PTGE). The structural, crystallinity, opacity, micromorphology, and thermal stability of the resultant SPI/HNTs/PVA/PTGE film were analyzed by the Attenuated total reflectance-Fourier transformed infrared (ATR-FTIR) s...
