Mechanical Stability and Reversible Fracture of Vault Particles

Mechanical stability and reversible fracture of vault particles.

Vaults are the largest ribonucleoprotein particles found in eukaryotic cells, with an unclear cellular function and promising applications as vehicles for drug delivery. In this article, we examine the local stiffness of individual vaults and probe their structural stability with atomic force microscopy under physiological conditions. Our data show that the barrel, the central part of the vault...

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...

Thermal Stability and Dynamic Mechanical Properties of Nano and Micron-TiO2 Particles Reinforced Epoxy Composites: Effect of Mixing Method

Effect of mechanical stability on fracture healing--an update.

The effects of mechanical stability and mechanical stimulation have been studied extensively in vivo using a variety of animal models and stimulators. Early results indicated that stimulation does not significantly contribute to fracture healing. Lately, however, more rigid external stimulators that withstand increased callus formation have identified a contribution of mechanical stimulation in...
