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 adays,the...

Sub-Lethal Effect of Four Plant Extracts on Growth And Reproductive Parameters of Culex pipines molestus Forskal (Diptera: Culicidae)

JOURNAL OF EDUCATION AND SCIENCE, Volume 28, Issue 1, Pages 1-8

The ethanol extracts of leaves Alianthus altissima, Carrisa grandiflora, fruits of Citrullus colocynthis and aerial parts of Ruta graveolens was tested against fourth instar larvae of the mosquito, Culex pipines molestua Forskal through sublethal doses at the concentrations 5, 10, 15 and 20 ppm. The extracts of C. grandiflora, A. altissima and R. graveolens were prolonged IV-P time with 9.7, 10.3 and 12.8 days at 20 ppm. Whereas, the period shorted to 4.3 days for C. colocynthis in comparison with control 7.3 days. All the plant extracts extended pupal period with significant time, but not more 3.1 days, and 2.1 days for untreated pupae. The reproductive parameters as egg laying hatchability, fecunidity, fertility and sterility percent were showed significant values of emerged adults treated with the plant extracts at IV larval instar.
 

Antimicrobial Activity of Some Trichoderma spp. against Different Kinds of Fungal and Bacterial Isolates

Omar Mu'ayad Al-Obaidy

JOURNAL OF EDUCATION AND SCIENCE, Volume 28, Issue 1, Pages 9-16

Two types of the fungus Trichoderma were chosen, these are T.viride and T.harzianum. The activity of these fungi were tested against different kinds of plant and human pathogenic fungi. After screening , the fungus T.harzianum was selected because it showed highest efficiency in its antagonistic activity than T.viride. It was also tested against other kinds of the plant and human pathogenic fungi and the fungus Macrophomina phaseolina was the most sensitive toward T.harzianum. In addition, the active compound from the fungus T.harzianum was extracted then tested against different types of pathogenic fungi and different types of pathogenic Gram positive and negative bacteria which showed different values of antagonistic activity. Bacillus subtilis was the most sensitive to the extract. Thus, many tests could be done to ensure the safety of this fungus (and its extract) and that is not toxic and to ensure its antagonistic activity toward the studied microbes inside the living body (In-Vivo), and then it could be used as good alternative to the chemicals that have side effects.

In Silico Structural Analysis of The Cell Division Protein, FtsZ: Screening Natural Products for Inhibitors

mohammed zaghlool saeed

JOURNAL OF EDUCATION AND SCIENCE, Volume 28, Issue 1, Pages 17-36

FtsZ is a tubulin homolog in bacteria. It forms a Z-ring to recruit other proteins in the process of cell division through its GTPase activity. Amino acid sequence of FtsZ was obtained from uniprot database and used for the determination of primary and secondary structures by several online tools. Homology modeling was carried out by SWISS-MODEL and PHYRE2. The models were evaluated and quality assessment indicated that the model produced by SWISS-MODEL had better quality than PHYRE2. Therefore, SWISS-MODEL was used in docking twenty five natural products by AutoDock 4.2.6. Dunnianol, pebrellin, dalbinol and hederagenin had docking energy higher than the previously used berberine and sanguinarine. Analogs of Dunnianol were sketched by ChemBioOffice Ultra 11.0 and docked. The analogs 2,4 and 7 had higher docking energy than the original compound. These natural products and the analogs obtained in this study could serve as possible inhibitors of this cell division protein, a new target in the development of new antimicrobials.
 

iD-Sets and Associated Separation Axioms

JOURNAL OF EDUCATION AND SCIENCE, Volume 28, Issue 1, Pages 37-46

In this paper, we introduce iD-sets which are depends on i-open sets [12]. Where we discussed the relationship between this sets and other types of sets, In addition, we discussed the relationship between the separation axioms for this type of sets with one hand and their relationship with i-separation axioms [1] on the other hand. Also we introduce i-symmetric typological space and the weakly -space. The most important results that we have obtained i-symmetric topological space which topologically extended for i-open sets will be -space if and only if it is - Space.

Automatic Continuity of Some Types of Double Derivations on Semisimple Banach Algebras

JOURNAL OF EDUCATION AND SCIENCE, Volume 28, Issue 1, Pages 62-70

         Following Villena in [9] and Mohammed and Ali in [4],  we introduce
partially defined ( ) - c - double derivation and generalized ( ) - c -
double derivation  on a semisimple complex Banach algebra  whose  domain
is not necessarily closed,  essential ideal and we prove that they are closable.
In particular, we show that every ( )- c -double derivation and generalized
( ) - c - double derivation  defined  on  any  nonzero  ideal  of  a prime  
C * -  algebra are continuous.
Keywords:  automatic continuity ,    double derivation ,   ultraprimness,

Study of Stability of Non-linear Model with Hyperbolic Secant Function

JOURNAL OF EDUCATION AND SCIENCE, Volume 28, Issue 1, Pages 106-120

We study a new definition of a non-linear model of time series with hyperbolic secant function in a discrete time. The suggested model consist of two parts the first part is (linear) and the second part is (non-linear) which contains the hyperbolic secant function. We approximate this model to be linear by using the local linearization technique. We find the non-zero unique singular point that satisfies the non-linear variation equation, also stability of the non-zero unique singular point and the limit cycle if it exists of the suggested model.

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.

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.

A. M. S. Al-Delymi; T. S. Al-Ghabsha

JOURNAL OF EDUCATION AND SCIENCE, Volume 21, Issue 29, Pages 62-71

ABSTRACT
A simple, rapid and sensitive spectrophotometric method for the determination of noradrenaline was developed. The method is based on the proton transfer reaction with alizarin red sulphonate (ARS) in aqueous neutral solution to form violet product showing maximum absorbance at 530 nm with molar absorptivity of 6720 l.mol-1.cm-1. The method follows Beer’s law over the concentration range (0.5-10) g.ml-1. The accuracy (average recovery) of the method is 100.29% and the precision (RSD) of the method is less than 1%.
The method was successfully applied for the determination of noradrenaline in pharmaceutical formulation as injection and the results were in good agreement with the standard addition procedure.
