Comment on "Length scale dependence of DNA mechanical properties".
Recent experimental data [1–7] indicate that the elastic wormlike rod (WLR) model of DNA that works well on long length scales may break down on shorter scales relevant to biology. According to Noy and Golestanian (N&G) [8] molecular dynamics (MD) simulations predict DNA rigidity close to experimental data and confirm one scenario of such breakdown, namely, that for lengths of a few helical tur...
متن کاملLength scale dependence of DNA mechanical properties.
Although mechanical properties of DNA are well characterized at the kilobase-pair range, a number of recent experiments have suggested that DNA is more flexible at shorter length scales, which correspond to the regime that is crucial for cellular processes such as DNA packaging and gene regulation. Here, we perform a systematic study of the effective elastic properties of DNA at different lengt...
متن کاملReply to Comment on 'Length Scale Dependence of DNA Mechanical Properties'
In a Comment [1] on our recent study of the length scale dependence of DNA elasticity [2], Mazur brings up a number of technical points about the analysis of the MD trajectories used in our simulations, broadly categorized as concerns about equilibration and interpretation of the observed results. In Ref. [2], we compare the results we obtain for the segment with 4 DNA turns to that with 2 DNA ...

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...
15 صفحه اولDependence of some mechanical properties of elastic bands on the length and load time
We present a study of the maximum stress supported by elastics bands of nitrile as a function of the natural length and the load time. The maximum tension of rupture and the corresponding variation in length were found by measuring the elongation of an elastic band when a mass is suspended from its free end until it reaches the breaking point. The work done by non-conservative forces was calcul...
