A simple and accurate spectrophotometric method has been described for the determination of frusemide in pharmaceutical preparation. The method is based on oxidative coupling reaction of frusemide with promethazine in aqueous acidic solution in the presence of hypochlorite ion and the absorbance of the blue product was measured at 625 nm against a reagent blank. The blue color formed immediately and stable for at least 24h. Calibration graph was rectinlinear for 2-20 ppm. The molar absorptivity is 0.625104.mol-1.cm-1, relative standard .

In the present work the synthesis of subtituted acetamidines was achieved. Phthalic anhydride was treated with p-aminobenzoic acid or glycine to give the corresponding acid which then converted to acid chloride with thionyl chloride. The acid chloride was treated with diethyl amine or dibutyl amine to give amides. The amides then converted to final products by their reaction with aniline or its substituents and POCl3. <br /> The structure of the synthesized compounds was confirmed by IR, UV and physical means.

In 1989, Dipper and Jamed 2 extend the notion of a Schur algebra, see Green 8, to obtain the q-Schur algebra Sq(n,r). One of the main difficulties that can not be solved is to determine a suitable mathematical formula for the product between two elements in Sq(n,r), except for the mathmatical formua introduced by Green in 8 and the <br /> programming formula that supported this formula which is given 11 when q=1.

In this paper a modified LBG vector quantization alglrithm id presented and used with wavelet transform algorithm to compress the image. The modified LBG algorithm provides good representation for training vectors carrying important information which may repesent rare vectors in the training vectors. So this algorithm overcomes the problem of the traditional LBG algorithm that provides good representation for training <br /> vectors which occur frequently while rare vectors are not well represented. The use of the modified LBG algorithm with wavelet transform give better reconstructed image quality than the traditional LBG algorithm because the rare vectors hich carry important information are better represented. The two algorithm give the same compression ratio.

10.33899/edusj.2006.77663
An Optical Character Recognition (OCR) approach for printed Arabic script is presented in this paper, Which is one of the most popular scripts in the world. Development of an OCR system. For Arabic script it is difficult because Arabic characters are distinct and many structurally similar characters exist in the character set.<br /> In the proposed approach, the technique can be divided into three major steps. The first step is digitization then do some pre-processing like segmentation to detect the slant of character and correct it .Second, feature extraction , using gray-level matrices. Finally, the K-Nearest-Neighbors is used for classification. This method was tested using 45<br /> patterns for each Arabic character with different fonts (simplified Arabic, tahoma, traditional Arabic), The sample images were divided into 20 training and 25 test images. Images in the test set did not appear in the training sets. This method performs extremely well with recognition rates .90.3%. This is a very good performance. All of this demonstrates that the new method is able to handle printed Arabic character task efficiently. It is a promising technique for recognition printed Arabic character.<br /> 1. Introduction Optical character recognition (OCR), deals with the recognition of optically processed character rather magnetically processed ones. In a typical OCR system, input characters are read and digitized by an optical scanner. Each character is then located, segmented and the resulting matrix is fed into a preprocessor. Off-line recognition can de considered the most general case: no special device is required for writing and signal interpretation is independent of signal generation, as in human recognition [6]. <br /> The recognition of Arabic character has been an area of great interest for many years, and a number of research papers and reports have already been published in this area. There are several major problems with Arabic character recognition: Arabic characters are distinct and ideographic, many structurally similar character exist in the character set Table (1). Thus, classification criteria are difficult to generate [1 J[3j[6].<br /> The Arabic language has a rich vocabulary. More than 200 million people speak this language as their native speaking, and over 1 billion people use its character set, such as Persian and Urdu, Due to the cursive nature of the script, there are several characteristic that make recognition of Arabic distinct from the recognition of Latin script or Chinese<br /> The study of Arabic character recognition has been regarded since 1980s. However, in comparison with the other languages, such as Latin, Chinese and Japanese, there is a little work has been conducted on the automatic recognition of Arabic character [4][5].

This projevt was undertaken to detect histovhemically the different <br /> types of carbohydrates in a recently described species of caryophyllid, Khawia grypi sp. N. using four techniques namely, periodic – Schiff reaction (PAS), Alcian blue (AB) technique (both at Ph 205 AND 1) AND Bests carmine (BC) technique. Tegument reacted intensely with (PAS), and moderately with (AB) (both Ph 2.5, and I) and negatively reactev by using (BC) . The muscle bundles were intensely reacted when using (BC) and negatively reacteve when using (AB) (Ph 2.5).<br /> The mesenchymal tissue was intensely to moderately reacted in the three techniques except (AB) (at Ph1). The excretory canals were just positively reacted except the reaction was negatively reacteve when using (AB) (Ph2.5).<br /> It has been concluded from the preset study that the Carbohydrates which were detected in the body wall contribute in protection, movement, absorption, and storage of energy, and the mesenchyma is the main site for the storage and distribution and metabolism of carbohydrates.

The present study dealt with the embryological eye development, growth of its tunics and optics as well as the external morphology of the developmental embryonic stages of the urodclc amphibian Neurergiis crocatus crocalus Cope.<br /> The gradual differentiation of eye layers progressed at late embryonic stages which extend between .35 —'39.At these stages the solera and choroids differentiate from mesenchymal cells that surround optic cup. On the other hand the differentiation of neural retina layers occurred. The first layer appeared was ganglion cells at the centrovenlra.l retina toward dorsoventral' retina of 36 stage. The lens fibers was also differentiate at this stage.At stage39distinct development of eye tunics and optics have been occurred, especially the neuralretina layers with increased thickness of the wjiole retina.. All retinal layers were conspicuous except the photoreceptor layer in which only the nuclei were distinct. The axons of ganglion cells bundled to form the optic nerve which penetrate the retina at the lower ventral margin.. The pigment epithelial which loaded with melanosomes also completed. The lens and cornea were became more distinct.<br /> .At 40 - 47 larval stages the integration and development of eye parts have been appeared, in that the photoreceptor (cones and rods) were more conspicuous, although the outer segments of these cells were unclear, the apical processes of pigment epithelium extended toward the photoreceptor, the optic nerve path deviated toward the central region of the eye ball and penetration of that region occurred at stage 47, in this<br /> stage the formation of ciliary body base, cornea, sclera and choraids were more conspicuous.<br /> Histolbgical structure of the adult eye of Neurergus cfocatus , crocatusresemble those of other urodele amphibians generally, in that the <br /> retina of duplex type. which consist of rods and cones.<br /> The cones nuclei location were vitred while the rods nuclei were sclered.The photoreceptor layer consist of single cone.

This study includes the isolation and identification of Staphylococcus aureus and Pseudomonas aerubinosa from Otitis Externa patients. Two hundred samples were collected, (191) samples showed a positive bacterial culture, this included (82) spccimwns of Ps.aeruginosa with percentage (41%) and (72) specimens of Staph. Aureus with percentage (63%).<br /> After detecting the inhibitory effect of plant extracts and active components on the bacteria under study, the results showed high inhibitory effect of aqueous and ethanolic extracts on Staph . aureus, while querctrin and catechin showed weak effect on Staph. Aureus. Ps. Aeruginosa showed resistance against aqueous, ethanolic and Quercetrin, while it showed weak sensitivity against Catechin.<br /> The Minimum Inhibitory Concentration (MIC) of aqueous extract against Staph. Aureus was (0.5) mg|cm3, while (MIC) of Catechin against Ps. AeruGinosa was (2) mg|cm3.

In this research histogram technique used lo extract the characteristic for. the images of Arabic characters, and evaluate their histogram values which used with Kohonen neural network as input, for recognizing the Arabic characters using intelligence methods.<br /> The Kohonen neural network has been trained on vertical histogramvalues for a set of letters including (ث ،ح ،د،ر،س ،ض ،ط ،غ ،ق ،ن) printed with Simplified Arabic font type, size 14, and then it has been test the network on another set of character that has not been trained by the network, the results were converging very well, and also it has been test on a set of noisy letters images, where the results were achieved true 100% , and then it has been test on a set of larger size character images (size 18 point), and also the results were not different with the previous. Also, it has been trained the network by using horizontal histogram for the same group of characters, and test the network on another set of characters that has not been trained by the network, and the results had lower closeness from the results that obtained with vertical histogram, and the closeness was more decreasing when has been testing on a set of noisy letters images, and also it has been test on a set of larger size letters images (size 18 point), and the results were achieved true 66% .<br /> So, it is discern previously that depending on vertical histogram values gives higher closeness from horizontal histogram vales. And when.<br /> depending on the two histograms together, it was gives bad results with other neural network as well as kohonen neural network.

In this paper we study some different method for solving volterra integral equation with singular kernel of the first kind and expanded by using a method for finding the solution using Gamma function when f(x) is an algebraic function and α known. Also we expand the result in case of f(x) is an algebraic function as a polonomial .
