journal of al-qadisiyah for pure science(quarterly), 2008, Volume 8, Issue 1, Pages 269-279

Abstract: The nonlinear behavior of fluid flow and effected of varying temperature at heated plate in an enclosure rectangular box are emphasized in this work. This problem is simulated by using a new version of differential quadrature method that is called "upwind differential quadrature(UDQM)" to demonstrated the effects of a heated through natural convection motion equation. By using UDQM, this problem is handled and good numerical results were obtained that are in agreement with that in literature.

journal of al-qadisiyah for pure science(quarterly), 2008, Volume 8, Issue 1, Pages 428-438

The present study was undertaken in 90 subjects, 30 non diabetic as normal control (groupI), 30 diabetics without complication (group II) and 30 diabetics with complication (group III). Blood sugar levels, Magnesium, C-reactive protein (SRP), Glycosylated hemoglobin (HbA1c), Cholesterol, Triglyceride, HDL and LDL were analyzed from serum of patients and controls group. Serum magnesium levels in group III were found to be significantly lowered (1.24±0.28meq/l) than in group I (2.56±0.58). There was also significant difference in magnesium levels of group II and group I (2.56±0.58, 1.98±0.32 meq/l respectively).
The results also indicate that the diabetic patients showed significant rise in serum C-reactive protein (p<0.05), glycosylated hemoglobin (p<0.001), serum cholesterol, triglyceride (p < 0.01), HDL-cholesterol and LDL-cholesterol (p < 0.001) as compared to control. The C-reactive protein values in group I, group II and group III were measured as 2.46±3.66, 8.4±4.87and 10.6±6.44, respectively. These values were found to be significantly higher in group II and group III (p<0.05). The HbA1c (%) were measured as 4.89±0.68, 8.66±0.77and 10.88±1.23 respectively. These values were also found to be significantly higher in group II and group III (p<0.001) .The aim of this study was to evaluate the serum of magnesium, C-reactive protein, Glycated hemoglobin (HbA1c) and lipid profile status.

Introduction : Clays are among the most important constituents of the earth crust .clays of smectite type such as bentonite montmorillionite , beidellite and hectorite have layered structure.
The sheet that constituents the mineral is called dioctahedral , and comprises an octahedral layer of aluminum surrounded by tow tetrahedral layers of silicon the cohesion between the layers is ensured by pooling oxygen atoms.

Abstract
5-[phenyl azo ]-4,6-dihydrexoy-2-mercapto pyrimidin.(PDMP)has been used for the determination of palladium (П) at trace levels .The inner complex of pd (II) with PDMP at acidic pH , is soluble in aqueous solutions .The complex has a maximum absorption at 572 nm and εmax of 0.76 x 104 L. mol-1.cm-1 . A linear correlation (0.1-5 μg/ml) was found between absorbance at λmax and concentration .The accuracy and reproducibility of the determination method for various known amounts of palladium(П) were tested .The results obtained are both precise (RSD was better than 0.60%) and accurate (relative error was better than 0.55%).The effect of diverse ions on the determination of palladium(П) to investigate the selectivity of the method were also studied .The stability constant of the product under optimized conditions and at room temperature was 1.25x108 L. mol-1.

Ammar K. M. AL-Ba

journal of al-qadisiyah for pure science(quarterly), 2008, Volume 8, Issue 1, Pages 344-351

This paper describes in details methods of preparation of some new organometallic monomers and polymers based on Tellurium and the thermal study of these compounds. The monomers synthesized are : Bis (4-aminophenyl) ditelluride and Bis (4-aminophenyl)telluride. The dimethylolic derivatives of the new former monomers were prepared by condensation with formaldehyde in a-one-pot reaction system at definite temperature and pH. The dimethylolic organometallic monomers were cured thermally to give their corresponding setting polymers. The new monomers and polymers were characterized using infrared spectroscopy and differential scanning calorimetric (DSC) techniques. Characteristics of the newest class polymers, namely electrical conductivity and thermal stability will be explored in further reports.

journal of al-qadisiyah for pure science(quarterly), 2008, Volume 8, Issue 1, Pages 316-322

Abstract:
Wavelet transform can decompose images into various multi resolution sub bands. In these sub bands the correlation exists. Most edge detectors are based on- local measurements of the image variations and edges are generally defined as 'block' where the image intensity has a maximum variation[1]. The image variations can be examined by derivative operators, such as gradient, Laplacian, Sobel and Roberts operators. In this paper we have used a standard method of edge detection Sobal, Perwit, Robert, Kirsch and Robinson. In addition we have used the wavelet transform in three levels, in each of these level the HL, LH return to the original size. Also,a hybrid method (wave late transform + perwit) to improve the image edge detection have been used.More over the standard deviation to the (2*2) block of the (LL)in the level (3) has been applied. The threshold to the block of the of HL, LH,HH of different size in the level 3,2,1 has been computed compared with the standard deviation results of the third (LL) band. And when the comparison completed we shall construct the image and finally apply the Perwit operator to the constructed image.

Suppose that (Xt)tI is an adapted sequence of d-dimensional random variable defined on some filtered probability space (,F,{Ft}tI,,P).

In this paper we obtain conditions which are necessary and sufficient for the existence of a probability measure Q to P (which we call an equivalent -measure) such that each of the d component sequence of (Xt)tI has a prescribed martingale property with respect to Q.This problem have been solved in L0-space with respect to -norm topology
