In the present paper, applicability of the modified fixed grid finite element method in solution of three dimensional elasticity problems of functionally graded materials is investigated. In the non-boundary-fitted meshes, the elements are not conforming to the domain boundaries and the boundary nodes which are used in the traditional finite element method for the application of boundary condit...

The long interspersed repeated DNA family of rats (LINE or L1Rn family) contains about 40,000 6.7-kilobase (kb) long members (1). LINE members may be currently mobile since their presence or absence causes allelic variation at three single copy loci (2, 3): insulin 1, Moloney leukemia virus integration 2 (Mlvi-2) (4), and immunoglobulin heavy chain (Igh). To characterize target sites for LINE i...

Let k be a positive integer, and suppose that the number of elements of a group G that are not k th powers in G is nonzero but finite. If G is finite, we obtain an upper bound on |G|, and we present some conditions sufficient to guarantee that G actually is finite.

Introduction: One of the vital enzymes during spermatogenesis, which is one of the pluripotency factors of stem cells and contributes to maintaining their pluripotency is alkaline phosphatase. ZBTB16 and ZFP proteins are critical elements in stem cells which are expressed in pluripotent stem cells and maintain their pluripotency due to their role in messaging pathways. Material & Methods: The ...

the mobility and bioavailability of trace elements in the agricultural soils are extremely important in assessing the risk of toxicity to the growing plants. a five step sequential extraction procedure (sep) has been employed to study the speciation of as, sb, cr, cu, cd, pb, zn, ni, fe and mn in 18 soil samples neighboring an industrial complex in isfahan, central iran. enrichment factor (ef) ...
