About Journal

Difining summary about the Journal Education and science magazine The first volume of the magazine was published in 1979 including papers on both pure sciences and human sciences. Then in 1987 the magazine started to publish papers in two independent volumes: one for pure sciences and the other one was for human sciences. The magazine stoped being published from 1981 to 1987 because of the Iraqi-Irania war and also in 1992 due to the sanctions imposed on iraq. The magazine is well-known inside and outside iraq in that 30 scientific establishments were publishing their papers in it. Now...

Synthesis of five membered ring hetero cyclic compounds derived from methyl-6- methyl-2- oxo-4-substituted 1,2,3,4- tetrahydro pyrimidine-5-carboxylate

Shaima S. Ismmaeel

JOURNAL OF EDUCATION AND SCIENCE, Volume 27, Issue 2, Pages 1-14

In this paper the synthesis of methyl-6- methyl-2-oxo-4-substituted phenyl-1,2,3,4-tetrahydropyrimidine-5-carboxylate (1-3) were synthesised from substituted benzaldehyde, urea and methyl acetoacetate, substituted pyrimidine (1-3) were treated with hydrazine hydrate in butanol to give acid hydrazide (4-6), which were converted to hydrazones (7-12) by their reaction with substituted benzaldehyde. Cyclizatian of hydrazones (7-12) with lead dioxide in glacial acetic acid gave substituted 1,3,4- oxadiazole (13-18). Hydrazide (4-6) were treated with ammonium
thiocyanate in ethanol and hydrochloric acid to give substituted
thiosemicarbazides(19-21). Reaction of thiosemicarbazide (19-21) with
4% sodium hydroxide or with concentrated sulfuric acid gave substituted
1,2,4- (4H) - triazole (22-24) and 1,3,4- thiadiazole (25-27)
respectively.
The structure of the synthesized compounds, were confirmed by IR, UV
and physical methods.

Physical and Chemical Methods Used for Determination of Structures of Some Imines Derived from Different Carbonyl Compounds

A.S.P.Azzouz; D.B.T.Bakzo

JOURNAL OF EDUCATION AND SCIENCE, Volume 27, Issue 2, Pages 15-27

The project is concerned with the preparation of fifteen imines derived from 2-acetyl pyridine ,3 or 4 –hydroxy benzaldehyde and m-anisaldehyde with aromatic primary amines by standard method .
These imines include namely ,hydroxylamine hydrochloride,o,m,p-amino phenols ,4-amino naphthol ,bromo or chloro aniline and p-anisidine .
The main aims of the study is the determination of structures of these imines by the available physical method ,namely ,the melting points ,boiling points , U.V and IR spectra . Some chemical tests for functional groups are also included .This seems important from chemistry point of view as in the elucidation of tautomerism reactions happen in some oximes and phenolic oximes . Finally ,the influence of inter molecular hydrogen bonding on association (polymerization) of imines was also discussed

Sahla Mohamed Zeadan

JOURNAL OF EDUCATION AND SCIENCE, Volume 27, Issue 2, Pages 39-47

The study succeeded in establishing a fine cell suspension derived from callus of carnation, Dianthus caryophyllus L. Hypocotyle explants in liquid MS medium supplemented with 0.5 mgL-1 2,4-D and 0.1 mgL-1 BA. The cells begin its first division within 24 h. These cell were continued their subsequent divisions to produce 142x103 cell/ml culture after five days of initiation. Results indicated that exposure of cell suspension to 20, 25, 30, 35, 40, 45, and 50oC short-term 5, 10 min. and long-term 15-20 min. stimulate the division of cells suspension in all treatments. Heat shock sustained the division of cell cultured in multiple drop array (MDA) technique and increase the formation of cellular colonies which produced a numerous of calli primordia. The total number of colonies was 959 developed when cells exposed to with the short-term 35oC/5 min heat shock. The produced calli was green in colour and friable in texture.

Better Adaptive Text Compression Scheme

Duha Amir Sultan

JOURNAL OF EDUCATION AND SCIENCE, Volume 27, Issue 2, Pages 48-57

A data compression scheme suggested by Ziv and Lempel, LZ77, is applied to text compression. A slightly modified version suggested by Storer and Szymanski ,LZSS, is found to achieve compression ratios as good as most existing schemes for a wide range of texts. In these two methods and all other dynamic methods, a text file is searched from left to right to find the longest match between the lookahead buffer (the previously encoded text) and the characters to be encoded. The method suggested in this work depends the searching in two directions, from left to right and from right to left, although this process takes more time, better compression results were obtained

are presented, which produce sufficient descent search direction at every
iteration. This methods showed globally convergent under some
assumptions. The numerical results show that all this new hybrid method
are efficient for the given test problems.

A Numerical Method for Accelerating the Convergence of the Power Method

Ekhlass S. Al-Rawi

JOURNAL OF EDUCATION AND SCIENCE, Volume 22, Issue 35, Pages 132-146

ABSTRACT
This paper describes a procedure which combines between the Wilkinson and Aitken methods in order to obtain a best approximation of the greatest eigenvalue. Both the symmetric and the nonsymmetric matrices are solved. It shows that our suggested method converges quickly and it is quit insensitive to the properties of the matrices used. A comparison between these approximations for five numerical examples is given, depending on the number of iterations and running computer time. Experimental results indicate that the new numerical procedure is more efficient than Power, Wilkinson and Aitken methods.

UTM coordinates correction between WGS84 and Clarke 1880 ellipsiod in Mosul by using GPS

Sabah H.Ali

JOURNAL OF EDUCATION AND SCIENCE, Volume 17, Issue 7, Pages 142-153

Most GPS receivers calculate their locations by a geodetic coordinate referenced to the WGS84 ellipsoid, whereas the local reference applied in IRAQ (referred as ClarkelSSO ellipsoid) have different geodetic coordinates.
This paper presents the results of particulars conversion between geographical and UTM grid coordinates system from WGS84 reference ellipsoid system to ClarkelSSO reference ellipsoid system for a selective locations in Mosul (Zone 38N). Conversion formulae and parameters are also given to facilitate users to convert the coordinates of any point in the study area between the two systems by using GPS.receiver and ArcGIS software.
The result shows that the geographical and UTM grid systems of the two systems are slightly different, but additive constants are sufficient to attain the general accuracy.

ABSTRACT
Ethanolic extract of the flower-head of matricaria chamomilla which growing in Iraq showed the presence at last of two new flavonoids quercetin (III) and isorhamnetin (IV), which gave a bright yellow colour during TLC separating under U.V light. These compounds were investigated on the basis of the comparison of their Rf-values in tables and using quercetin as authentic sample for comparison.

A new self scaling PCG algorithm with dynamical retards

ABBAS Y. AL-BAYATI; ASEEL MOAYAD QASIM

JOURNAL OF EDUCATION AND SCIENCE, Volume 21, Issue 25, Pages 113-134

Abstract
The problem of optimizing a certain systems as a function of time may be formulated in terms of maximizing or minimizing a non-linear cost function. It was found that a Dynamic Programming (DP) algorithm was particularly efficient procedure for solving this problem compared with an alternative nonlinear programming method.
In this work, a new CG method with dynamical retards is generalized and combined in a dynamical way with non-monotone globalization strategies to obtain a new type CG-algorithm for minimizing non-quadratic functions that can deal efficiently with large scale nonlinear optimization problems.
