A class of new solutions for Einstein’s field equations, by choosing the ansatz e?(r)=1+kr2R21+r2R2 metric potential, are obtained under Karmarkar condition. It is found that a number pulsars like 4U 1820-30, PSR J1903+327, 1608-52, Vela X-1, J1614-2230, Cen X-3 can be accomodated in this model. We have displayed nature physical parameters and energy conditions throughout distribution using num...

water stress effects on winter and spring leaves anatomy were investigated in experiments conducted at the experimental field of sb university of kerman using five wheat cultivars.xylem and phloem elements diameter and mesophyll, bundle sheath and epidermal cells area were measured in transverse sections prepared from middle parts of the leaves. results showed that significant difference exists...

abstract the lack of water is the most important problem in extensive landscape especially turfgrass in arid and semi arid regions. the root responses in native and commercial grasses under drought stress were investigated. this experiment was in a factorial experiment based on unbalanced completely random design on the year 2006. the specious that we used in this experiment included (i) commer...

The mechanical behavior of cold rolled sheets is significantly related to residual stresses that arise from bending and unbending processes. Measurement of residual stresses is mostly limited to surface measurement techniques. Experimental determination of stress variation through thickness is difficult and time-consuming. This paper presents a closed form solution for residual stresses, in whi...
