This paper presents a new type of encryption, using a matrix asymmetric and symmetric matrix inverse matrix clear text, which is an internal encryption. As well as asymmetric encryption, where the ciphertext is inversely symmetric matrix. Decryption matrix related to any asymmetric encryption keys depends on public and private, and is applied to the coded messages used in the current system ASCII our computers.

This research studies the notion of non-equivalence in translation between English and Arabic. It displays the main issues translators face when translating, like cultural restraints and linguistic barriers. It also suggests a number of strategies that help in dealing with non-equivalence, including paraphrasing, omission, and cultural substitution.
This research gives a new type of encryption, using vectors give me a private encryption key, which generates a triangular matrices from the top (bottom), and check conditions matrix Hill. These matrices resulting from private vectors constitute a relatively preliminary numbers of size n = 256 The encryption process produces by multiplying the original matrix encryption keys.
this paper, we generalize the study of the mathematical operations over (2x2), (3x3) and (4x4) real matrices by using the complex numbers which was introduced by (Ide. 1990,1993,1996), for any real matrices (nxm). This method of arithmetic operati ons of matrices by using the complex numbers and its properties is simple, easy and fast to program on computer. The importance of this method appears in the applications of problems which use the arithmetic operations of matrices, especially in physics.
The present study aims to develop sustained release (SR) matrix tablets of methyldopa using hydrophilic hydroxypropyl methylcellulose (HPMC), and to study the effect of some formulation variables (HPMC concentration and viscosity grade, combination with hydrophobic Ethylcellulose (EC) in different ratio, binder and lubricants concentrations) on the properties of prepared tablets. Matrix tablets were prepared by wet granulation method, and prepared granules and tablets were subjected to suitable physiochemical studies. Drug release kinetics showed that drug release mechanism for about all formulations was found to fit best to Higuchi model and drug release mechanism was anomalous diffusion based on release exponent value. The in-vitro dissolution studies showed that formulation F6 containing 15% of HPMC K100M and formulation F11 containing EC:HPMC K4M (5%:10%) were able to sustain the release of methyldopa up to 24 hours so these two formulations were selected as suitable formulations.
Indubitably, elements constituting the syntactic structure are one of the significant linguistic features of the symmetrical discourse in the linguistic order whether poetry or prose; since the symmetry discourse consists of two, or more, adjacent li nguistic series. However, the symmetrical discourse is one form of syntactic arrangements, as appears in organizing the text, and dividing it into similar constituents that soon bring forward a recognizable rhythmical dimension, which becomes clear in how long or short the tone is, whether this symmetrical discourse is full or partial, divided into longer stretches, or shorter ones interconnected by the conjunction 'and'. No doubt that such a type of linguistic discourse, which divides the text into similar segments, acquires it harmony and cadence apparently missing in any other linguistic structure.
