sensitive spectrophotometer method for the determination of 4-aminoantipyrine in pure as well as in pharmaceutical dosage form is reported, based on the preparation of Schiff base as a chalet ligand by condensation reaction of 4-aminoantipyrine with Isatin to give (1-phenyl-2,3dimethyl-4Isatidine-5-oxopyrazole) followed by the preparation of three new complexes for this ligand with Cr(III),Ni(II),and Cu(II) in alcoholic media. These prepared complexes were characterized by C.H.N.,F.T.I.R.,electronic spectra,molar conductivity,magnetic sensitivity and measurements of metal ratio by flame atomic absorption technique.Beer's law was obeyed in the concentration ranges (5-400) µg.ml-1,(7-300) µg.ml-1&(10-250) µg.ml-1 with a detection limit(D.L) of (0.18) µg.ml-1,(0.25) µg.ml-1&(0.33) µg.ml-1 for Cr(III),Ni(II) & Cu(II)

This research considers the problem of scheduling jobs on a single machine to minimize the objective function , the sum of completion time .The jobs partitioned into families , and a set-up time is necessary for scheduling the first job and when there is a switch in processing jobs from one family to jobs of another family . To solve this problem some known approximation methods are modified , namely the tree type heuristic (TTH) and tow local search methods descend method (DM) and simulated annealing method (SAM) . The performance of approximation methods can be tested on a large class of test problem

The susceptibility of five isolates of Staphylococcus aureus which isolated from wound infections were determind against ciprofloxacin & Fusidic acid .The findings have shown that ciprofloxacin & Fusidic acid were highly effective on S. aureus isolates when the Minimum Inhibitory Concentration (MIC) was very low .

Fibrous gypsum veins development in claystone host rock has been studied in southern Himrin Mountain area, northeast Miqdadiya east of Iraq. Three groups of veins have been recognized: (1) Simple fibrous veins, which contain perpendicular or inclined fibres to vein walls, their straight fibres extend between vein walls and these veins were affected by one opening direction, (2) Moderately complicated fibrous veins, which contain curving fibres either at vein walls or at vein centre. These veins were affected by two different opening directions, and (3) Complicated fibrous veins, which contain multicurved fibres in different places. These veins were affected by more than two different opening directions.

There is an important need in the industrial applications to have a control system by which we can control the flow rate ,pressure ,and differential pressure of a fluid especially in the Industrial applications.

The fractional order partial differential equations (FPDEs) are generalizations of classical partial differential equations (PDEs).


In this paper we examine the stability of the explicit and implicit finite difference methods to solve the initial-boundary value problem of the hyperbolic for one-sided and two sided fractional order partial differential equations (FPDEs). The stability (and convergence) result of this problem is discussed by using the Fourier series method (Von Neumann¢s Method).

A new Schiff base ligand [L] [3-methyl-9,10 phenyl -6,7 dihydro-5,8 –dioxo-1,2 diazo –cyclo dodecu 2,11-diene ,4-one ] and its complexes with (Co(II), Ni(II), Cu (II), Zn(II) and Cd(II)) were synthesis.This ligand was prepared in three steps, in the first step a solution of salicyladehyed in methanol reacted under refluxed with hydrazine monohydrate to give an (intermediate compound 1) which reacted in the second step with sodium pyruvate to give an (intermediate compound 2) which gave the ligand [L] in the three step when it reacted with 1,2- dichloro ethane.The complexes were synthesized by direct reaction of the corresponding metal chloride with the ligand. The ligand and complexes were characterized by spectroscopic methods [IR, UV-Vis,HPLC and atomic absorption], chloride content in addition to conductivity measurement.From the obtained data the propose chemical formula for complexes [M(L)]Cl2 (M= Co(II),Ni(II),Cu (II),Zn(II)andCd(II)) are distorted tetrahedral structure about metal ions for the studied complexes.

151 isolates of Azospirillum were identified out of 289 nitrogen fixing bacteria, these isolates were obtained from soil rhizosphere and sterilized rice roots of different regions in Iraq, by using biochemical and physiological characters, the isolates were differentiated into three species namely: A. brasilense, A. Lipoferum, and A. irakense and their numbers were 88,16 and 47 respectively. All isolates of A. irakense (except two) were obtained from sterilized root. By using modified Red Congo medium for isolation, purification and identification. The isolates were classified into three groups (A, B and C) according to colony colors. The results indicated that there is a relationship between biochemical characters and textures, shapes , colors of the colonies. It seems that there is a similarity between colonies of the same group, which differ from the other groups.

The effect of amikacin on proteuse mirabilis virulence factors expression were examined. Exposure of bacterial cell to different concentrations of amikacin caused inhibition of swarming ability of P. mirabilis. The expression of virulence factors heamolysin was aiso inhibited by amikacin.


It was found that amikacin at concentration 2µ/ml could inhibit swarming activities, the production of urease and haemolysin was not affected by low concentration of amikacin but was inhibited by high concentration of it.


These results indicate the impact of amikacin on the virulence factors with P.mirabilis isolate.

It had been measure some of Physical properties ( linear shrinkage, total density, apparent porosity, water absorption ) for a porcelain models have been made by using (kaolin alien , glass sand earth , Potassium feldsapr ) . the raw materials were prepared by washing , drying , grinding , and particles size distribution process . Then there groups of the raw materials which preparation by ( Binder , Plasticizer , lubricant ) depending on the three pyramidal substances of variable rates . After that many groups of ceramic materials were introduced that consist of (95%) of each the (35%) kaolin alien , (35%) of potassium feldspar and (25%) of glass sand earth each plus (5%) of amount of the plasticized materials of of previous groups and leaving over the grains rate of each of the kaolin lien , the glass sand earth , and the potassium feldspar on all the groups. These samples were formed by Hot compression. Then the models were incinerated under three different temperatures (1250,1300,1350Co) with a maturity period of (2hr) and an elevation speed of (2Co/mine). After that the Physical properties were measure on these samples . The results of this research has shown that the best temperature degree for felting the models is (1350Co) . Though the best results achieved was for the additive (75% B+ 15%P+10%L). The results of this research has shown that the Iraqi caly is liable for use its raw materials

In this paper we have examined the effect of the altitude and latitude on the total intensity () and the horizontal component () of the internal and external geomagnetic field at the location (lat 3.5°N, long 96°E) west of Sumatra (one of the Indonesia's islands ).We examine the relationship between the () with altitude at a certain latitude, and relationship between (F,H) with the latitude at the certain altitude .We study also the nature of the secular variation of the geomagnetic field at the same location during the epoch (1965-2010) .

The [2-aminobenzothiazole]was reacted with [2,4,6 triyhydroxy-acetophenon monohydrate] to give a new ligand [2-N-2,4,6-trihydroxyacetophenonyliden benzothiazole] [H3L]. This ligand was reacted with metal ions ( CoII, NiII,CuII and ZnII) in methanol as solvent with ( 1:2 ) metal : ligand ratio to give a series of new complexes with general formula [ M(H2L)2],(where:M= CoII, NiII ,CuIIand, ZnII).All compounds were characterized by spectroscopic methods ( I.R , U.V – vis,HPLC) atomic absorption, along with chloride content and conductivity measurements. According to the data of these measurements we suggested a tetrahedral geometry for (CoII, NiII,CuII, and, ZnII ) complexes.
