Protein synthesis on the ribosome involves hydrolysis of GTP in several key steps of the mRNA translation cycle. These steps are catalyzed by the translational GTPases of which elongation factor Tu (EF-Tu) is the fastest GTPase known. Here, we use extensive computer simulations to explore the origin of its remarkably high catalytic rate on the ribosome and show that it is made possible by a ver...

Understanding the function of vastus lateralis (VL) and medialis (VM) muscles is important since these are essential for daily sport activities. The association between knee flexion angle spatial muscle activation controversial. This study compares distribution patterns multi-channel electromyographic activities VL VM at three angles intensities isometric contraction. Sixteen men performed exte...

in this paper, second law analysis for calculations of the entropy generation due to the flow andheat transfer of water-al2o3 and ethylene glycol-al2o3 nanofluids inside annuli is presented. thephysical properties of the nanofluids are calculated using empirical correlations. constant heatfluxes at inner surface of the annuli are considered and fully developed condition for fluid flowand heat t...

a review of damages caused by landslide shows the need for studying effective parameters in landslide occurrence and prediction. this study aims to improve landslide prediction results for tutkabon region in gilan province. to this end, shannon entropy theory was employed for modeling and considering data uncertainty. slope, height, geomorphologic conditions, earth’s curve, closeness to river, ...

let $g$ be a finite simple graph whose vertices and edges are weighted by two functions. in this paper we shall define and calculate entropy of a dynamical system on weights of the graph $g$, by using the weights of vertices and edges of $g$. we examine the conditions under which entropy of the dynamical system is zero, possitive or $+infty$. at the end it is shown that, for $rin [0,+infty]$, t...

Developing highly stable cathode materials is the key to achieving long-life K-ion batteries (KIBs). Considering that with higher entropy can promote ion adsorption process, we developed a method heat treatment and synergistic electro-activation of 3,4,9,10-perylene-tetracarboxylic dianhydride (EA-PTCDA) realize increase in PTCDA, which achieves storage. From our characterization results, molec...

An AlCoCrFeNiY high-entropy alloy coating was prepared using air plasma spray. The cyclic oxidation behavior of the investigated and compared with that a conventional NiCoCrAlY coating. It is demonstrated exhibits much stronger resistance to spallation than when they are thermally cycled between room temperature 1050-1150 °C. difference attributed lower growth rate oxide scale on as result its ...
