Influences of alfalfa powder concentration and granularity on the dynamic theological properties of alfalfa-wheat dough was studied. Frequency sweep tests at 25 degrees C and 80 degrees C and temperature sweep tests from 25 degrees C to 80 degrees C were applied to wheat dough samples. Elastic moduli (G') and viscous moduli (G '') of the alfalfa-wheat dough at 80 degrees C were higher than those of the alfalfa-wheat dough at 25 degrees C. The viscoelastic moduli (G' and G '') of the alfalfa-wheat dough at 80 degrees C showed less frequency dependence compared to those of the samples at 25 degrees C. The viscoelastic moduli (G' and G '') of alfalfa-wheat dough increased with the increasing of alfalfa powder concentration from 0% to 10% and decreased with further increase in alfalfa powder concentration from 10% to 20% at 25 degrees C. All the alfalfa-added samples showed a delay in the dough gelatinization temperature comparing with the control sample. On the other hand, the viscoelastic moduli (G' and G '') increased with the increase of alfalfa powder granularity distributed from 80-100 to 40-60 mesh.

Effects of Defatted Flaxseed Addition on Rheological Properties of Wheat Flour Slurry HAO, Changchun; Lİ, Dong; Mao, Zhihuai; Özkan, Necati; Chen, Xiao Dong (2013-12-01) Rheological property of defatted flaxseed-added wheat flour dispersions was investigated as a function of defatted flaxseed concentration (0-20%), NaCl concentration (0, 0.6, and 1.2%), sucrose concentration (0, 5, and 10%), and slurry concentration (33and 62.5%). Frequency sweep tests at 20 degrees C and temperature sweep tests from 20 to 90 degrees C were applied to the samples. The experimental measurements demonstrated that the viscoelastic moduli of samples increased with the increase in defatted flaxs...
Evaluation of natural zeolite as a viscosity-modifying agent for cement-based grouts Sahmaran, M.; Özkan, Necati; Keskin, Serhat; UZAL, BURAK; Yaman, İsmail Özgür; Erdem, T. K. (2008-07-01) The effects of natural zeolite on the theological and workability properties of the grout mixtures were studied. Setting times of grouts were also determined as part of the experimental study. For comparison, grout mixtures were also prepared with a commercially available viscosity modifying admixture (VMA). The experimental results show that addition of natural zeolite modifies both the rheological and workability properties of grouts. For a constant superplasticizer (SP) content, an increase in the zeolit...
Effect of microstructure on the tribological properties of apatite-wollastonite glass ceramic Park, Jong-Ee; Öztürk, Abdullah; You, Sang-Hee; Park, Sam-Sik; Bae, Won-Tae; Shin, Dong-Woo (2008-06-01) A relationship between microstructure and the tribological properties of Apatite-Wollastonite glass ceramics (A-W GC), fabricated by different techniques of melt casting and powder packing processing, was studied. The surface crystallization of wollastonite caused a unique surface strengthening in an A-W GC prepared by the melt casting process. The wear rate did not vary between the free surface and interior in an A-W GC made by the powder packing process, whereas an increase of the wear rate with an increa...
Influence of nature of silica source on template-free synthesis of ZSM-5 Kalıpçılar, Halil (Wiley, 2001-01-01) Synthesis of ZSM-5 from template-free batches which preceded the preparation of template-free ZSM-5 layers on porous supports was studied to ascertain the effect of nature of silica source on the purity of template-free ZSM-5. Silicic acid and two colloidal silica sols were used as silica sources to prepare the template-free batches with a molar composition of 6.5Na(2)O:Al2O3:80SiO(2):3196H(2)O. One of the colloidal silica sols contained methanol as stabilizer while the other did not. The product purity and...
Effect of cold stress on antioxidant mechanism of winter and spring type barley (hordeum vulgare L.) cultivars Afşar, Nilüfer; Yücel, Ayşe Meral; Department of Biochemistry (2007) In this study, effect of cold stress on physiology and biochemistry of two Turkish barley cultivars, winter type Tarm-92 and spring type Zafer-160, was studied. For chilling stress treatment, cultivars were exposed to +4 ºC for 1, 3 and 7 days, and for freezing stress application acclimated cultivars (+4 ºC for 3 days) were treated with -3 ºC and -7 ºC. After freezing stress treatment, a recovery period was applied for 4 days at 4 ºC. Following analyses were performed on leaf and root tissues: growth parame...
