Determination

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Structure Determination

Most of the protein structures described and discussed in this book have been determined either by X-ray crystallography or by nuclear magnetic resonance (NMR) spectroscopy. Although these techniques both depend on data derived from physical techniques for probing structure, their interpretation is not unambiguous and entails assumptions and approximations often depending upon knowledge of the ...

Sex determination

Of all the differences that distinguish people, the most obvious and most intriguing one is their sex. The relationship between males and females has had a profound influence on human civilization, causing wars and societal up heavals, and inspiring countless works of art, music and literature. For as long as humans have both struggled with and enjoyed the existence of the two sexes, they have ...

Sex determination

struggled for years with parasites that evolve resistance to commonly used drugs. Why should it be any different in animals? Yet as far as we know, no study has ever looked at whether parasites become resistant to the chemicals in the plants that hosts use for protection, though in the Drosophila example referenced above, ethanol did not negatively affect larvae of specialist wasps as strongly ...
