Organic–inorganic hybrid coatings were prepared by sol–gel method and deposited on aluminum alloy 6061. Attenuated Total Reflectance-Fourier Transform Infrared (ATR-FTIR) spectroscopy and Scanning Electron Microscopy (SEM) were used for structural study of the hybrid coatings. Adhesive strength of sol–gel coatings to the substrate was evaluated quantitatively and qualitat...
A series of gels differing in ionic content was prepared by derivatizing starch with varying amounts of carboxymethyl add-on. Some derivatives were lightly crosslinked with epichlorohydrin to reduce soluble material and increase the amount of gel. The gel fraction of each batch was isolated. and viscosity 1]. shear modulus G. and swelling in water and salt solution were then determined. One gel...
Agar extraction for Gracilaria corticata by investigating the effects of various extraction variables such as soaking time, soaking temperature, seaweed to water ratio, extraction temperatures and extraction time and also Alkali treatment method. The results showed that agar yield was significantly affected by all the tested variables. The agar yield was maximized when extraction process was ca...
Polysulfide is well known elastomer for use in aerospace applications due to providing flexible coating and chemically resistant sealants. In this work, the effects of carbon black content on curing behavior of polysulfide elastomer were investigated and Rheological properties for samples with different filler content 15, 20 and 25 phr were evaluated by rheometric mechanical spectrometer RMS. A...
because of the harmful effects of chemicals on human health and environment, use of these compounds in postharvest technology of agricultural crops is recently restricted and it is necessary to find safe compounds for use in postharvest technology of fruits and vegetables. in this study, effects of salicylic acid and aloe vera gel on quality attributes and postharvest life of table grape(cv. gi...
Sesame is an annual self-pollinated plant with a high seed oil and protein content. It is considered as an oilseed plant for human consumption. For a breeding purpore, quantitative and qualitative characteristics of seed total protein of different sesame varieties (Oltan, Zoodras , Yekta , Hendi , Varamin , Chini , Karaj 1 , Moghan local,Nazok tak sakheh and Nazok chand shakheh) were evaluated....
Objective- This study was designed to investigate the effect of Lactobacillus plantarum gel on cutaneous burn wound healing in diabetic rats.Design- Randomized experimental studyAnimals- Forty adult male ratsProcedures- Two circular 1 cm cutaneous wounds were created in the dorsum back of each rat. 48 h post-burning, debridement with a 1 cm biopsy punch was performed. The woun...
Impact of bambara groundnut protein isolate (BGPI) on autolysis and gel properties of surimi from lizard fish was investigated. As the levels of BGPI increased (0-3%), breaking force, deformation and retention/ stability of myosin heavy chain (MHC) of modori gel markedly increased (P<0.05). Nevertheless, only 0.25% BGPI increased above parameters in kamaboko gel. A decreasing trend in whiteness...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
