On plotting the derived data points with ln k versus 1/T, a line-graph exhibiting a linear relationship between ln k and 1/T is generated, as shown. The slope of the line, which corresponds to the activation energy, can be estimated using any two of the experimental data pairs. An ...
Therefore it is not really possible to determine the correct activation energy from a single non-isothermal curve. On the other hand, when a set of curves are recorded under different heating schedules are used, the correct kinetic parameters can be clearly discerned. Conclusions Here, it is ...
The paper considers a mathematically correct approach to define the rate-determining steps, rate-determining parameters as well as the apparent activation energy for steady occurrence of stepwise reactions with a known reaction scheme. Examples of the application of the suggested approach to analysis of...
The "apparent activation energy" of concrete—Ea—is usually determined by means of mechanical or calorimetric tests. This parameter, which characterises the sensitivity of concrete hydration processes to temperature, is required for estimating the compressive strength of concrete at early age by the "...
Experimental values of activation energies of the reactions H+R'X → HX + R'and R+ R'X → RX + RX + R'(X=Cl, Br, K; R and R' -alkyl radicals) are analyzed in the framework of the model of transition state with two crossing Morse curves, one of which characterizes breaking bon...
The article suggests a determining relation of the creep limit that takes the dependence of the activation energy on the temperature into account. The model contains two constants of the material and a function of the temperature which is integrated as short-time ultimate strength (σ u ). Corre...
such as heterotrimeric G proteins1,2. The activation of the major classes of GPCRs engages additional helix macro-switches, including movements of the cytosolic region of TM5 and rotations of TM3, and residue micro-switches, which are unique for each class, except for classes A and B1 sharing...
a protein is often the result of physical processes that transport density over space and tend to preserve local geometry. From two-dimensional image data, 3DFlex enables the determination of high-resolution 3D density, and provides an explicit model of a flexible protein’s motion over its ...
After transformation, plants that are homozygous and contain one copy of the transgene are typically selected for further study. If real-time PCR is to be used to determine copy number and zygosity, it must be able to distinguish hemizygous from homozygo
