Rasha Abdulaziz Faris Abdulghafor Ibrahim Abdullah

JOURNAL OF EDUCATION AND SCIENCE, Volume 24, Issue 1, Pages 49-60
DOI: 10.33899/edusj.2011.51503

Abstract
Three proposals of large pitch (Λ=5µm) photonic crystal fibers (PCFs) are studied. The effect of air hole radius on the properties of the fundamental mode of these fibers are considered. All the parameters of the proposed structured were kept constant except the hole radius were varied 0.5, 0.8, and 1.0μm for the PCF1, PCF2 and PCF3 respectively.
Numerical aperture, effective area, nonlinear coefficient, dispersion, flattened dispersion, dispersion slope and zero dispersion wavelength of the PCFs were all investigated.
This study shows that the dispersion profile was affected by the radius of the hole and PCF3 showed more flattened dispersion (dispersion slope of 0.015333ps/nm2.km), in range of 1.2~1.5μm of wavelength compared to PCF1 and PCF2 structures. On other hand, the increase of air hole radius increased the numerical aperture and decreased the effective area along the full range of wavelength, while zero dispersion point was shifted towards the shorter wavelength.
The calculated results were compared with other published work of small pitch (Λ=2.3µm) photonic crystal fiber.

Creating Image Mosaics using Statistical Methods for Images Alignment

Israa Mohammad Khidher Mohammed A. M. Al-taee

JOURNAL OF EDUCATION AND SCIENCE, Volume 24, Issue 1, Pages 93-107
DOI: 10.33899/edusj.2011.51409

Abstract
Image mosaics is a collection of small images arranged in a way that when they are seen from a distance they seen as larger image. It occupies a wide field in computer vision and image processing area. This field is performed in four stages. These stages are selecting the target image (input image) stage, choosing the tiling pattern stage. These tiles are small images from image database. The third stage arranged the tiles in a way to cover the target image. Indeed, color correction stage where the image colors are adjusted to better match the target image colors. The aim of our work is to create an image mosaics based on Statistical approaches.
Database images are collected and selected randomly. Then these images are pr-processed through a resized operation. Also a color transformation from RGB to the grayscale form (intensity). The color transformation is necessary because the intensity form shows the details of the target and the tile images to obtain effective images matching. At first we select a target image randomly. The target image is segmented to 32x32 tiles. At the second stage we choose the rectangular pattern for its simplicity as well as the rectangular nature of tile images used. Arranging tile stage is obtained, for each tile the system search the image database and selects the best matching image based on correlation coefficients of the intensity images. At this stage the difference between our works than others appeared. We use the correlation coefficients for matching operation that obtain a best matching than other approaches like Mathematical approaches which obtained approximate results such as distance functions. Also other Statistical approaches such as Histogram intersection and Statistics measure (Chi Square) used to arrange tiles operation. Finally, we perform image color correction in pixel wise using the average of the R, G, B channels of the target and tile images. The resultant pixel obtained from last step will cover the target. As a result an image mosaic is created. The proposed work shows efficient and accurate results.

ABSTRACT
The present study was investigated the immunological effects of the lipopolysaccharide extracted from Klebsiella pneumoniae against experimental infection with toxoplasmosis in mice.
Immunological changes in treated mice were compared with the +ve (mice infected with T.gondii but not treated with LPS) and -ve (mice not infected with T.gondii and not treated with LPS) group at 3,14 and 30 days post infection with tissue cysts of T.gondii in the peritoneal cavity. Total and differential WBC count of peripheral blood and innate immune response represented by the phagocytic index were the criteria taken into consideration.
Results showed a significant increase in the total WBC count in mice treated with LPS after infection with T.gondii, compared with –ve and +ve control groups. For differential WBC count, an increase in lymphocytes and decrease in monocytes, neutrophils and eosinophils was noticed. Basophils were not considered because of their low number.For phagocytic index, an increase was noticed in treated mice compared with –ve and +ve control groups, and the highest rate was observed in cncentration 500 µg / 20 gm body weight at 30 days post infection.
It is concluded that, LPS extracted from K.pneumoniae may well be used as a active and non toxic immunomodulator against infection with toxoplasmosis in mice.

Abstract
To investigate the interaction effect of iron-deficiency anemia and feeding soybean in different ratios and treatments to wheat flour, 84 albino male growing rats were used as biological model in this study. They aged 24-35 days and body weight 60-74 gr. They were divided randamlly into two main groups. First group contained healthy rats, which inturn divided into seven equal subgroups according to hemoglobin level and body mass. Second group contained induced anemic rats (iron depleted by bleeding about 15-20 drops of blood) divided into seven equal subgroups also. Both anemic and healthy groups were fed for 15 days experimental period the balanced experimental diets as follows: Wheat flour (WF, control diet), WF supplemented with 7.5% or 15% ground soybean seeds, WF supplemented with 7.5% or 15% germinated soybean seeds, WF supplemented with 7.5% or 15% fermented soybean seeds. Nutritional status, body weight gain, hemoglobin levels, growth rate, amount of diets consumed, feces eliminated weights, dietary and fecal iron contents, liver and spleen weights and their iron contents were estimated, dietary apparent iron absorption (AFeA%) and dry matter absorption (DMA%) were calculated.
Analysis of variance and Duncan multiple tests of body weight gains, growth rates, amount of diets consumed, feces eliminated and their iron contents, liver and spleen weights, and their iron content values of anemic rats were lower than those of healthy rats. However, the AFeA% of anemic rats was higher than those values of healthy rats. Dry matter absorption was similar in both groups of rats. 15% germinated soybean seeds supplementation to WF indicated to have promising effects in preventing and treatment of iron-deficiency anemia.

JOURNAL OF EDUCATION AND SCIENCE, Volume 24, Issue 1, Pages 100-113
DOI: 10.33899/edusj.1999.51508

Abstract
The present work, six different equations of state (EOS), have been used for studying Copper under high pressure at room temperature, by studying variation of different thermodynamical parameters in particular, variations in bulk modulus and Grüneisen parameter, which are represent a promising approach for modeling universal EOS for solids.
On comparing our predicted results, obtained by using the different EOS, with experimental data, one notice that all the six EOS gives agreement with experimental data for relatively low pressure. The best agreement with experimental data, with increasing pressure, have been shown by the results calculated by Bardeen, Brennan – Stacey and Vinet EOS. While results predicted by using Birch – Murnaghan EOS shows slightly less agreement with experimental data.
The results calculated by using both Murnaghan EOS and Thomsen EOS at higher pressure shows disagreement with experimental data and with our theoretical results.
