We present a model for single-motor molecules--myosin, dynein, or kinesin--that is powered either by thermal fluctuations or by conformational change. In the thermally driven model, the cross-bridge fluctuates about its equilibrium position against an elastic restoring force. The attachment and detachment of the cross-bridge are determined by modeling the electrostatic attraction between the cr...
پایین بودن ظرفیت گرمای ویژه ی هوا و همچنین، پایین بودن ضریب انتقال حرارت جابه جایی مابین سیال هوای عبوری از مجرای کالکتور و صفحه ی جاذب حرارت، از مشکلات اصلی استفاده سیال هوا در کالکتورهای تخت خورشیدی می باشد. ایجاد ناهمواری در زیر صفحه ی جاذب حرارت از جمله روش های موثر در افزایش ضریب انتقال حرارت جابه جایی، شکستن زیرلایه ی آرام، به منظور افزایش سطح و زمان تماس هوا با صفحه ی جاذب حرارت در جریان...
The competition plot is a method for determining whether or not two enzyme-catalysed reactions occur at the same active site. It is a plot of total rate against p, where p varies from 0 to 1 and specifies the concentrations (1-p)a0 and pb0 of two substrates in terms of reference concentrations a0 and b0 chosen so as to give the same rates at p = 0 and p = 1. If the two substrates react at the s...
S U M M A R Y Wepresent and use a phase coherence approach to identify seismic signals that have similar path effects but different source time functions: co-located earthquakes and tremor. Themethod used is a phase coherence-based implementation of empirical matched field processing, modified to suit tremor analysis. It works by comparing the frequency-domain phases of waveforms generated by t...
Politicians all over the world are investing considerable time and effort in both creating and curating social media profiles, with many sending hundreds or even thousands of messages over social platforms during election time, often with the help of trained and professional staff. However, there have been only a handful of papers that have sought to test whether active campaigning on social me...
High temperature Fischer-Tropsch synthesis process use fixed fluidized bed as a reactor. In order to understand the flow behavior in the fluidized bed better, the research of how the radial velocity affects the entire flow field is necessary. Laser Doppler Velocimetry (LDV) was used to study the radial velocity distribution along the diameter direction of the cross-section of the particle in a ...
In this paper, effects of the cross shore and groyne wall slopes on flow parameters around an impermeable groyne were considered using a three-dimensional numerical CFD model (i.e., FLUENT). The k-ε turbulence model was used to evaluate the Reynolds stresses. The model was first applied to a vertical groyne on a flat bed and the model results were compared with the relevant experimental data. T...
Linear stability analysis of the three dimensional plane wake flow is performed using a mapped finite di?erence scheme in a domain which is doubly infinite in the cross–stream direction of wake flow. The physical domain in cross–stream direction is mapped to the computational domain using a cotangent mapping of the form y = ?cot(??). The Squire transformation [2], proposed by Squire, is also us...
at present study the flow and heat transfer of non-newtonian nanofluid, aqueous solution of carboxymethyl cellulose-aluminum oxide with different volume fractions of nano particles in a two dimensional microtube is simulated for the first time. slip velocity and temperature jump boundary conditions are also considered along the microtube walls. the achieved results accuracy is investigated by c...
