The hydrogen abstraction reaction of OH radical with CH3CH2OCF2CHF2 (HFE-374pc2) is investigated theoretically by semi-classical transition state theory. The stationary points on the potential energy surface of the reaction are located by using KMLYP density functional method along with 6-311++G(d,p) basis set. Vibrational anharmonicity coefficients, ...

The characteristic dependence of the intensity of transition radiation (TR) on the Lorentz factor g 1⁄4 E=mc of a primary particle is key to a number of practical applications. In particular, one may use TR detectors for energy measurements of heavy cosmic-ray nuclei in a region where alternate techniques are difficult to apply. However, a serious constraint can be the saturation of the TR yiel...

The study of electron-positron collisions at center-of-mass energies corresponding to charmonium production has reached new levels of sensitivity thanks to experiments by the BES and CLEO Collaborations. Final states γP , where P is a pseudoscalar meson such as π, η, and η can arise either from charmonium decays or in the continuum through a virtual photon: ee → γ → γP . Estimates of this latte...

In this Research, the transition from equilibrium ignition to non-equilibrium burn was studied by DEIRA4 code for simple spherical targets with the dimensions of several mm. It consisted of inner DT fuel and outer Au layers driven by the 209Bi heavy ions beam. Because of their higher plasma opacity, it was expected that they could trap much of the produced charged particles, radiation or even f...

this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...

Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...

for several years, researchers in familiarity of efl teachers with post-method and its role in second and foreign language learners’ productions have pointed out that the opportunity to plan for a task generally develops language learners’ development (ellis, 2005). it is important to mention that the critical varies in language teaching was shown is the disappearances of the concept of method ...

In this paper, we have implemented a three-body formalism, where the interaction potential is replaced by the transition matrix, in the excitation channel for the collision of positron and atomic hydrogen. Differential and total cross sections are calculated while the first and second order terms of the FWL (Faddeev-Watson-Lovelace) series in the transition from ground state to the first excite...

Environmental quality is affected by many factors such as economic and political inequality. The main purpose of this article is to investigate the effects of income and political inequality on the environment quality in the selected countries. Using the Generalized Method of Moments (GMM), the effects of gini coefficient, democracy index and income per capita, energy consumption and human deve...
