heteropoly acids (hpa) and their salts have advantages as catalysts which make them both economically and environmentally attractive, strong br?nsted acidity, exhibiting fast reversible multi-electron redox transformations under rather mild conditions, very high solubility in polar solvents, fairly high thermal stability in the solid states, and efficient oxidizing ability, so that they are imp...

This perspective on Tsao et al. (beginning on p. 931 in this issue of the journal) discusses green tea extract, which was shown for the first time to have dose-dependent effects in a clinical chemopreventive setting (oral premalignant lesions). This translational trial provides important data on angiogenesis and other biomarkers on which to base future clinical research, which should include tr...

برای حل معادله انتقال حرارت در بافت، تابع گرین یک لایه پوست، از سطح تا اولین رگ خونی را در مختصات استوانه ای با شرایط مرزی روی z حل کرده ایم، که از لحاظ فیزیکی، بیشترین تشابه را با مساله واقعی دارد. به این دلیل که مدل لامبرت-بیر، مدل کاملی نیست و گستردگی باریکه را در نظر نگرفته است، همچنین در محیط بافت با پراکندگی زیاد، ایرادهایی دارد، از مدل ولش به عنوان تابع منبع استفاده نموده ایم، که این م...
