the strong ground motions recorded during the 2002 avaj earthquake have been used to estimates wave attenuation, qβ, and spectral decay parameter, κ, for the avaj region. qβ for shear wave is estimatedas a function of frequency in the range of 0.6- 18 hz. the results show that qβ increases with frequency in theform of qβ=62.7 f 0.9. our estimates are within the estimated range for different par...

a systematic study on the electrochemical behavior of the s-derivatives of 2-amino cyclopentene-1-dithiocarboxylic acid (acda) has been carried out in aqueous ethanolic solutions by means of polarography, coulometry and voltammetry. all the compounds studied exhibited a well defined anodic wave corresponding to a diffusion controlled process. controlled potential coulometry gave n=1 per mole fo...

A pole in the Dπ S-wave analogous to the σ and κ is predicted at M− iΓ/2 = 2098± 40− i(260 ± 40) MeV. The main objective of this paper is to provide formulae for fitting it to data. PACS numbers: 12.39.Ki, 13.25.Gv, 14.40.Lb. There are well-known σ and κ poles in ππ and Kπ. The objective of this paper is to predict analogous poles in Dπ and Bπ S-waves and provide appropriate parametrisations of...

In the s-wave approximation the 4D Einstein gravity with scalar fields can be reduced to an effective 2D dilaton gravity coupled nonminimally to the matter fields. We study the leading order (tree level) vertices. The 4-particle matrix element is calculated explicitly. It is interpreted as scattering with formation of a virtual black hole state. As one novel feature we predict the gravitational...

In the present investigation, we study the reflection of plane waves, that is, Longitudinal displacement wave(P-Wave), Thermal wave(T-Wave) and Mass Diffusive wave(MD-Wave) in thermodiffusion elastic-half medium which is subjected to impedence boundary condition in context of one relaxatioon time theory given by Lord and Shulman theory (L-S) and the Coupled theory (C-T) of thermoelasticity. The...
