stress is a word that can be used to explain the way we feel, or it can be used to describe something that happens to someone. for most pregnant woman, pregnancy is a happy and breathtaking time, however, pregnant for some woman can be a source of stress, depression and anxiety. these factors can be risk factors for adverse outcomes for mothers and children. anxiety in pregnancy is associated w...

the lut block (eastern iran) extends over 900 km in a north-south direction and is only 200 km wide in an east-west direction. it is confined by the nayband fault and shotori range on the west. the eastern edge is bordered by the sistan suture zone and nehbandan fault. the northern termination of lut block is the depression of kavir-e-namak and the great kavir fault. the makran arc, including t...

The operation of a single Frank–Read (FR) source in the presence of a spatial stress gradient is studied using 3D discrete-dislocation dynamics (DDD) simulations and analytic models. Under a sufficiently large stress gradient, the FR source shows a new stable configuration controlled by the low-stress region of the graded stress field. Successive emissions from the source generate a growing dis...

a dynamic two dimensional problem of thermoelasticity with double porous structure has been considered to investigate the disturbance due to normal force and thermal source. laplace and fourier transform technique is applied to the governing equations to solve the problem. the transformed components of stress and temperature distribution are obtained .the resulting expressions are obtained in t...

The occurrence of SH wave propagation under the effect of a point source in an orthotropic substratum lying over a heterogeneous orthotropic half space is deliberated in the prospect of a devastating earthquake. The quadratic alteration is acknowledged for density and shear modulus which is hypothesized to be a function of depth. The method of Green's function and transformation technique contr...
