Strengthening of concrete structures is applied as a solution for various deterioration problems in civil engineering practice. This paper presents an analytical study the behaviour cross-section reinforced (RC) beam, strengthened flexure with fiber polymer (FRP) materials. Using balance internal forces cross section through all phases stress which passes, program was written MATLsoftware, exec...

We study twist-three effects in spin, charge, and azimuthal asymmetries in deeply virtual Compton scattering on a spin-zero target. Contributions which are power suppressed in 1/Q generate a new azimuthal angle dependence of the cross section which is not present in the leading twist results. On the other hand the leading twist terms are not modified by the twist three contributions. They may g...

This paper considers alternative approaches to the analysis of large panel data models in the presence of error cross section dependence. A popular method for modelling such dependence uses a factor error structure. Such models raise new problems for estimation and inference. This paper compares two alternative methods for carrying out estimation and inference in panels with a multifactor error...

Twist-three analysis of photon electroproduction off pion. Abstract We study twist-three effects in spin, charge, and azimuthal asymmetries in deeply virtual Compton scattering off a spin-zero target. Power suppressed contributions generate a new azimuthal angle dependence in the cross section, not present in the leading twist approximation. On the other hand the structures induced by the latte...

Saturation at low x appears as an almost unavoidable consequence of the two-gluon exchange generic structure. Consistency of the ansatz for the vector part of the color dipole cross section with conventional evolution determines the energy dependence of the saturation scale. In this written version of my talk I will restrict myself to a discussion of the empirical evidence for the concept of " ...

The influence of medium correction from an isospin dependent nucleon nucleon cross section on the fragmentation and nucleon emission in the intermediate energy heavy ion collisions was studied by using an isospin dependent quantum molecular dynamical model (IQMD). We found that the medium correction enhances the dependence of multiplicity of intermediate mass fragment Nimf and the number of nuc...

The penetration of solar H Lyman-α radiation into the terrestrial middle atmosphere is studied in detail. The Lyman-α actinic flux is calculated with a Monte Carlo approach including multiple resonance scattering of Lymanα photons within the terrestrial atmosphere and a temperature dependent absorption cross section of molecular oxygen. The dependence of the actinic flux on the temperature prof...

We study the nuclear (or A) dependence of the coherent photoproduction reaction in a relativistic impulse approximation approach. We use a standard relativistic parameterization of the elementary amplitude, based on a set of four Lorentz-and gauge-invariant amplitudes, to calculate the coherent cross section from 4 He, 12 C, and 40 Ca. In contrast to nonrelativistic treatments our approach main...

Using an isospin-dependent quantum molecular dynamics, nuclear stopping in intermediate heavy ion collisions has been studied. The calculation has been done for colliding systems with different neutron-proton ratios in beam energy ranging from 15 MeV/ u to 150 MeV/ u. It is found that, in the energy region from above Fermi energy to 150 MeV/ u, nuclear stopping is very sensitive to the isospin ...
