Since last three decades there are close relationships between chaotic theory and cryptographic theory. Chaotic system behaviors like; highly sensitive to initial states, mix up attribute, deterministic nature and also cannot predict the long term returns, these characteristics help the researchers to enhance security of a cryptography systems, therefore growing number of random numbers generators based on chaotic have been proposed. These proposed generators suffer from limited key space and those based on 1D chaotic map have limited entropy generation capability due to their finite number of Lyapunov exponent(s). In this paper, we propose a random binary sequences generator that produces sequence of bits. General structure of proposed model consists of two parts, first part is mouse device as the nondeterministic source and second part is 3D chaotic system with the coordinates of mouse cursor when movement as the initial seeds, and combines the produced values in algorithmic process. The coordinates of mouse cursor are treated as initial random number with post processing with 3D chaotic maps to increase the randomness and security of the keys. The proposed work has high key space and very long period. Also make obvious that the generated keys possess successful statistical characteristics which is expected of true random binary sequences that are suitable to use in critical cryptography systems, these made by evaluating the results by hardness of 16 tests of NIST(National Institute of Standards and Technology).

The matrix element have the main role in the transition rates of nuclear reactions. In the present work, different formulae of matrix elements for pre – equilibrium nuclear reactions have been tested wide ranges of energy, which ranged from 0 to 200 MeV. It's found that the two recent formulae of Koning with and without asymptotic value deviate at high energy with old one that was suggested by Kalbach. The differential cross section was calculated using these formulae and comparison between them and with available experimental were made. This comparison showed a good agreement between the studied matrix formulae and the experimental formulae.

Single crystals of copper sulfate pentahydrate (CSP) were grown up to (21.6×19.38×3 mm3), (14.5×34.11×42.3 mm3) and (42.4×27.36×7.5 mm3) from aqueous solution by slow evaporation technique at room temperature using double distilled water, H2SO4 acid and magnetic water as solvents respectively. Structure analysis of grown crystals was carried out by X-ray diffraction technique. The study of the vibrational modes for the grown crystals was conducted by FTIR spectroscopy. It is observed that the H2SO4 acid led to the disappearance of Cu+2 metal ion (Cu-O-H) mode in crystal, while the magnetic water led to appearance of it with less intensity compared by appearing in the crystals grown using distilled water. The UV-Visible result shows that the crystals have cut-off at 280 nm, 292 nm and 287 nm, with optical energy gap (4.23 eV, 4 eV and 4.09 eV) for crystals grown using distilled water, diluted acid and magnetic water as a solvent respectively.

The Shiranish Formation comprises the globigerinal marls and limestones of the Upper Senonian (Upper Campanian-Maestrichtian). The present study has been discussed the pertophysical properties of this marly rocks in Kirkuk oil field (K-260 and K-229). The study area is located in northeastern Iraq (Kirkuk areas). This area lies within the Zagros foreland basin, bordered on the northeast by the Zagros Mountains and on the southeast by the Arabian Shield, and consists of linear and high amplitude folds that trend in a northwest-southeast direction. The Shiranish Formation was deposited during the transgression period after the sea level fall marked by the glauconitic contact (SBI) with the Kometan Formation. According to the general facies observation with the gamma ray and resistivity logs patterns, there are two major units in this Formation. The first unit is represented by six cycles of transgressive system tracts (TST) which bounded the upper unit by maximum flooding surface; the second unit is represented by three cycles of high system tracts which unconformably underlying of Aaliji Formation. According to the porosity type and the conductivity properties in addition to decreasing and increasing of shale effect (Gamma Ray) for the Shiranish Formation within K-260 and K-229 there are five petrophysical zones. These zones may be divided in to two Groups:- A. Low petrophysical properties rocks, this include the zones II and IV. B. Good petrophysical properties rocks, this include the zones I, III and V. The zones of group B are important rock units because there are shows of fractured porosity and gas effects in the zones three and five. Where, the zone three is represents a gas effect when the neutron and density porosity are extrusive. While the zone five are represent the fractured porosity in addition to present of gas effects. The first zone is different from the previous two types by the type of rock is limestone and the fabric/porous type is moldic and intragranular grainstone. At the last of this study the researcher is suggested that the Shiranish Formation may be a good reservoir rocks (fractured reservoir).
