Using polymer elastic theory and known RNA free energies, we construct a Monte Carlo algorithm to simulate the single RNA folding and unfolding by mechanical force on the secondary structure level. For the constant force ensemble, we simulate the force-extension curves of the P5ab, P5abc deltaA, and P5abc molecules in equilibrium. For the constant extension ensemble, we focus on the mechanical ...

Ammoniated electrons exist in solutions of potassium amide in liquid ammonia which have reached thermodynamic equilibrium with hydrogen gas. By determining electron concentrations by electron spin resonance, an equilibrium constant of 10(5) at room temperature has been obtained.

abstract siderophores are of important factors influencing bioavailability and fate of heavy metals in the arid and semi-arid soils. they are low molecular weight organic ligands excreted by aerobic soil microorganisms and some plants roots to acquire fe. siderophores may also complex other metals such as pb .the main objective of this study was to investigate the effects of dfob-siderophore on...

A fully instrumented air conditioning laboratory unit capable of controlling drying air temperature and humidity integrated with an instantaneous weighing thin layer drying system was used to investigate the thin layer drying behavior and desorption equilibrium moisture content of canola (Brassica napus L.). To this aim, freshly harvested canola samples with moisture content of about 12±0.5% (d...

A mathematical method of determining the values at equilibrium and the constant rates in inter-conversion process of conformational labile molecules is proposed. No measuring method is used. In most of the cases, at equilibrium, the concentrations of the main species are equal. Thus, we have equilibrium of concentrations too. The symmetry plays a central role.  2012 Trade Science Inc.

Spectroelectrochemical studies of the intervalence charge transfer (IVCT) characteristics of both diastereoisomeric forms of the dinuclear complex [{Ru(bpy)2}2(mu-dpi-)]n+ [bpy=2,2'-bipyridine; dpi-=4,5-di(2-pyridyl)imidazolate] showed that the degree of inter-metal electronic coupling (or valence delocalization) is dependent on stereochemical identity. Increasing the relative concentration of ...

An algorithm is presented which enables one to determine the nature of the equilibrium state of a system with constant inputs by direct inspection of its bond graph representation. The algorithm determines whether or not there exists a unique equilibrium state (within a certain region). If not, the system may have no (or injinitely many) equilibrium states in the linear case.

in this paper the dynamic of a droplet on a surface with a hole is investigated under gravitational effect by using lattice boltzmann method. incompressible two-phase flow with high density ratio proposed by lee is considered. cahn’s theory is used to observe the wettability of the surface in contact with liquid and gas phases. several parameters such as contact angle, surface tension and gravi...

Computer simulations recently revealed that several liquids exhibit strong correlations between virial and potential energy equilibrium fluctuations in the NVT ensemble [U. R. Pedersen et al., Phys. Rev. Lett. 100, 015701 (2008)]. In order to investigate whether these correlations are present also far from equilibrium constant-volume aging following a temperature down jump from equilibrium was ...

simulation of metallurgical processes has been the subject of intense research due to the reduced number of experiments required for controlling the process as well as time and energy savings it allows. in gas carburizing of steel parts, the amount of carbon at the surface of carburized parts is the most important specification of the process in terms of achieving the desired metallurgical prop...
