To prepare a sheetable dough, potato granule and potato puree of Agria and Marfona potato-cultivars, corn flour, emulsifier ,shortening, water,starch, salt, garlic and pepper powder were used. Dough was sheeted to thickness of 1-2 mm and formed to desirable shape. These slices were baked at 125oC for 30 minutes. Prepared potato chips were packed in air or nitrogen atmosphere and stored in dark ...
In the present article, RRA, T73 and T6 heat treatments were carried out to improve mechanical properties of 7075 aluminum alloy and its hardness, tensile and bending strengths were evaluated. For this purpose, solution annealing was performed at 530 ºC for 16 h. For T6 treatment, aging was executed at 150 ºC for 24 h after solution annealing. In T73, aging treatment was done in two s...
COMPARISON BETWEEN THREE-POINT AND FOUR-POINT FLEXURAL TESTS 2 TO DETERMINE WOOD STRENGTH OF EUCALYPTUS SPECIMENS 3 Paulo Ricardo Gherardi HEIN*, Loïc BRANCHERIAU 4 *Corresponding author: [email protected] 5 Received: September 21, 2016 6 Accepted: January 24, 2018 7 Posted online: January 25, 2018 8 9 ABSTRACT 10 11 Comparison between flexural wood strength values obtained from three-poin...
in this study, the particleboard was made with rice husk and urea formaldehyde resin of 7, 8, 9 and 10 percent (based on dry weight of rice husk). to improve mechanism of bondability a definite amount of isocyanate resin is introduced to replace the same amount of urea formaldehyde resin. the effect of urea formaldehyde resin and diisocyanate content on bondability was evaluated by studying the...
in this study, rice husk and sodium silicate solution were used to produce particleboards. sodium silicate was used as bonding aid by 25, 20, 15, 10, 5 and zero percent (based on rice husk dry weight). to modify the mechanism of bondability, one percent of 4,4’-diphenylmethane diisocyanate (mdi) was added for every five percent less sodium silicate solution. the effect of diisocyanate on bondab...
Strength of both muscles and bone are important for fracture prevention in osteoporotic individuals. Therefore, drugs that are preclinically tested in animals for preventing or treating osteoporosis, and reducing fracture risk, should not only be checked for their effects on bone strength, but also for those on muscle strength. We developed a rat model to measure both in the same animal, using ...
The objective of this study was to manufacture particleboard made from UF with low formaldehyde (E1) for use in indoor environments. The influence of UF in particles on the formaldehyde emission and its mechanical properties were investigated. The experimental results showed that the formaldehyde emission released decreased linearly with consumption UF-low formaldehyde- particle. Formaldehyde e...
To clarify the mechanical properties of fiber-reinforced hybrid resin bridges, this study evaluated the influence of various bonding agents ((Modeling Liquid (ML), DE Resin (DE), Bell Bond (BE), Mega Bond (MG), Durafil Bond (DU), Fluoro Bond (FB), Mac-Bond (MC), EG Bond (EG), Unifill Bond (UN), Single Bond (SN)) impregnated with fibers on bending strength. FB attained the highest bending streng...
