the effect of enzymatic treatment time of microbial transglutaminase (mtgase) on the characteristics of whey protein isolate (wpi) films was investigated. results shown that the properties of mtgase-treated films were affected by increasing the enzymatic treatment time. enzymatic treatment at lower incubation time, i.e. for 1 h, significantly resulted in higher values of tensile strength (ts) a...

Modification of soy protein film properties by heat-curing was studied. Glycerin-plasticized films were cast from alkaline aqueous solutions of soy protein isolate. Films were heated at 80 or 95°C for 2, 6, 14, or 24 h. Tensile strength (TS), elongation at break (E), moisture content (MC), water solubility (WS), water vapor permeability (WVP), and color of heated and control films were measured...

A 23 factorial experimental design has been used to quantitatively study individual and interaction effects of the nature of binder (N), concentration of binder (C) and the applied pressure (P) on two mechanical properties, namely, tensile strength (TS) and brittle fracture index (BFI), of paracetamol tablets. The factorial design was also used to study the quantitative effects of coprocessing ...

The specific aim of this study was to measure the TS of rat skin wounds during the first week following surgical injury. Biomechanical and histological data were collected daily (days 1 to 7 following surgery) from separate groups of Sprague-Dawley rats (N = 12) each with two 3 cm long parallel skin incisions on the back. The wounds were immediately closed by four simple sutures. A control grou...

objectives: mineral trioxide aggregate (mta) is extensively used in endodontics. however, mta is difficult to handle because of its granular consistency, low mechanical properties and initial looseness. the objective of this study was to assess the compressive strength (cs), diametral tensile strength (dts), and ph of set mta using methyl cellulose as liquid. materials and methods: white proroo...

Gelatin films were prepared by casting. Tensile strength (TS) and elongation at break (Eb) of the gelatin films were found to be 46 MPa and 3.5%, respectively. Effect of gamma radiation (Co-60) on the thermo-mechanical properties of the gelatin films was studied. 2-hydroxyethyl methacrylate (HEMA) was added to the gelatin during casting varying (10% 30% by weight) and found to increase the TS s...

In this work, the effect of ageing and retrogression on polarization resistance Al 6061 was assessed, in order to improve corrosion alloy with a negligible tensile strength. The behavior studied by exposing an simulated marine environment, then, current density (icorr) measured. obtained results were correlated strength (TS) reported elsewhere both measured, icorr TS modeled multiple linear reg...

Aim of study: This study aimed to improve some physical, mechanical properties, and fire resistance wood-plastic composites (WPCs) with short glass fiber reinforcement (SGFR). Materials Methods: The WPCs were reinforced different ratios (SGF). effect on the water absorption (WA), thickness swelling (TS) as physical flexural strength, modulus elasticity, tensile strength properties determined. p...

EPM/EPDM elastomers are widely used for the insulation of high and medium voltage electric cables. Insulator mechanical properties depend on the extent of vulcanization, which is obtained by manufactures using a number of different peroxides as cross-linking agents. Vulcanization occurs in the continuous vulcanization tube, a pressurized tube filled with nitrogen at high temperatures. Then, wat...

The mechanical properties of dentin are changed after bleaching, although the effects of the bleaching conditions on the tensile strength of dentin have not been determined. In the current study, a tensile test of bovine dentin was conducted after bleaching and the effects of the bleaching conditions were investigated, including the number of bleaching times, the location where the bleaching ag...
