this study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond (prunus dulcis)kernel. raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (ph 5.0) and 0.02 mol dm-3 phosphate buffer solution (ph 7.0) at 25 and 40ºc, respectivel...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...
Human plasma: Dried human plasma (Nihon Seiyaku Co., Ltd.) was used. Commercial preparations of fibrinogen (Cohn's Fraction I, Armour Labora tory), thrombin (Mochida Co.) and streptokinase (Varidase, Lederle Lab. of American Cyamid Co.) were used in the following experiments. Plasminogen (Kline's preparation) was kindly donated by A .B. KABI. Urea solution of 0.4 M and 0.04 M, and the soltion o...
Introduction: The development and progress of computerized technologies has revolutionized radiology with digital imaging. The aim of this study is to compare Digital Radiography(DR) and Temporal Digital Subtraction (TDS)in detection of dentinal caries progression. Methods: 27carious teeth were placed in separate vials of sterile buffer solution after extraction .Three radiopaque restorations ...
Acetylene-reducing activity of detached pea nodules was determined by submerging the nodules in buffer solution [tris(hydroxymethyl)aminomethane-hydrochloride, pH 7.4] containing 100 mM sodium succinate and incubating under a gas phase of 90% O(2) and 10% C(2)H(2). The nitrogenase activity was 4 to 8 mumol of C(2)H(4) formed per g of nodule fresh weight per h and remained constant for at least ...
When living cells of Nitella are exposed to an acetate buffer solution until the pH value of the sap is decreased and subsequently placed in a solution of brilliant cresyl blue, the rate of penetration of dye into the vacuole is found to decrease in the majority of cases, and increase in other cases, as compared with the control cells which are transferred to the dye solution directly from tap ...
