نظریه هوش چندگانه قسمتهای متفاوت هوش بشری را مورد بررسی قرار می دهد که با شناخت آن شخص به درک بهتری از توانایی های خود میرسد و در نتیجه سعی در استفاده از آن جهت یادگیری بهتر میکند. همچنین با شناخت استعداد دانش آموزان، فرایند یادگیری بهتر میشود. هدف از انجام دادن این تحقیق بررسی رابطه بین هوش ریاضی و استعداد یادگیری زبان انگلیسی میباشد. برای انجام این تحقیق از پرسشنامه هوش ریاضی که توسط شیرر در ...
Iron binding of 3-hydroxychromone, 5-hydroxychromone, and sulfonated morin: Implications for the antioxidant activity of flavonols with competing metal binding sites.
The iron binding properties and antioxidant activities of compounds with hydroxy-keto binding sites, 3-hydroxychromone, 5-hydroxychromone, and sulfonated morin were investigated. For these compounds, prevention of iron-mediated DNA damage and kinetics of Fe(II) oxidation were studied in aqueous solutions close to physiological pH (pH 6). 3-Hydroxychromone and sulfonated morin inhibit iron-media...
