هدف اصلی این تحقیق بررسی تاثیر برنامه ریزی زمانی، هم چنین افزایش میزان پیچیدگی تکالیف در نظر گرفته شده بصورت همزمان، بر دقت و صحت و پیچیدگی عملکرد نوشتاری زبان آموزان می باشد. بدین منظور، 50 نفر از دانش آموزان دختر در رده ی سنی 16 الی 18 سال به عنوان شرکت کنندگان در این زمینه ی تحقیق در نظر گرفته شدند و به دو گروه آزمایشی و کنترل بصورت اتفاقی تقسیم شدند. اعضای گروه آزمایشی هر دو تکلیف ساده و پی...
Peroxidase-catalyzed Oxidation of Indole-3-acetic Acid.
The aerobic oxidation of indole-3-acetic acid catalyzed by horseradish peroxidase produces 1268 nm emission characteristic of singlet oxygen. Lactoperoxidase also oxidizes indole-3-acetic acid to produce singlet oxygen, but in contrast to horseradish peroxidase, this enzyme system requires hydrogen peroxide. In both of these systems, the intensity of the 1268 nm emission is small due to quenchi...
متن کاملStudies on the oxidation of indole-3-acetic Acid by peroxidase enzymes. I. Colorimetric determination of indole-3-acetic Acid oxidation products.
The method described here is based on a brief report by Harley-Mason and Archer. It involves the use of p-dimethylaminocinnamaldehyde (DMACA), a vinylogue of Ehrlich's reagent, as a color reagent for indoles. Colorimetric analyses of indoleacetic acid (IAA) oxidation reaction mixtures were made with the DMACA reagent as a solution rather than a spray. DMACA reagent will yield a wine-red color w...
