Twenty mature indigenous breed rabbits were used, the animals were divided into four groups(A, B, C, D, and E)
each group composed of four female and one male according to times of embryonic study which included ( 6, 8, 10, 12, 14)
days postnatal. This study showing the histological changes during the development of liver in early embryonic life by using
the H&E Stain. The results at six day of gestation differentiation of some structures as a clusters of stem cells in deferent
location of rabbit embryo. The cluster of stem cells will development into deferent organs in the next stage of development of
rabbit embryo. The result at eight day of gestation appear the liver as spherical structure near the heart development region
in addition to the appear of the other organs beside the fetal liver. At ten day of gestation the embryonic liver become more
prominent and differentiation inside the embryo. The twelve day of embryonic life the proliferation of hepatoblast and
showing in deferent figure of mitotic division. The result appear the primordial hepatoblast arranged as short hepatic cords
and located some of small lipid droplets in cytoplasm of hepatoblast. At fourteen day of gestation the hepatocytes arranged as
long hepatic cords, the lipid droplets disappear from the cytoplasm in addition to located high number of hematopoietic cells
have nucleus in blood stream, so the density of outer region of foetal liver more than the central region.

In this paper, we have discussed transistors made from single molecules in which one silver ion is connected
to gold electrodes by organic barriers. By tuning the length of the organic barrier we are able to control the coupling
between the ion and the electrodes. For relatively long linker molecules, giving weak coupling, the molecule functions
as a quantum dot. This work shows that the properties of a molecular transistor can be controlled by the physical
properties of the molecule .The ability to design the electronic states of a molecular device using (SIESTA and
Smeagol), together with the ability to measure individual molecules, will play an important role in molecular electronics
and in the physics of nanometer-scale systems. This paper is also to study electron transport in nanoscale objects,
especially the devices made from single molecules. We show that the qualitative features of this interference effect
arecaptured by the Smeagol COD described above through an appropriate choice of parameters. Finally, we note that
quantum interference in such multibranch structures leads tothe appearance of large, internal countercurrents, which
exceedthe external current carried by the electrodes, these calculations presented in this work were processing in Centre

In this paper, we provides two propositions that give a direct computing of the Elliptic Curve Discrete Logarithm
problem (ECDLP) and propose a method for the computation of discrete logarithms in the Elliptic Curve (EC) defined over
finite fields Fp .This propositions and propose method provides a new approach to the field of attacking methods of the
Elliptic Curve Cryptosystems. In addition, we give a program to implement the proposed method by using MATLAB.

In this paper, we have taken some interpolation points and found a polynomial passing through it by simple way.
Using a slave of a system of equations composed of interpolation points, such that the y-axis of this point will be as solution of
equations, and x-axis will be equations that find it by composition interpolation points with constant points to make a system of
polynomials, by solving this system we get a result of the constant points that will be shaped interpolation polynomial.
