Abstract

Theoretical study of ten crown ethers substituents were established to investigate some parameters that give clear view about their validity and applicability in the design of anticancer agents. Restricted hartree fock method (RHF/3-21G) were used to determine the energy difference between highest occupied molecular orbital and lowest unoccupied molecular orbital (HOMO-LUMO gap) , ionization energy, global hardness and total energy. Strong binding ability with potassium ion were obtained in some of these compounds depend on the type of substituents added to both nitrogen atoms out of the ring cavity. Such binding with potassium in abnormal and divided cancer cells result in inhibition of tumor cell growth by disrupting potassium ion homeostasis leading to kill ailing cells. Compound 10 represents the best suggested material which posses the potent anticancer activity due to its physicochemical properties required for anticancer drugs

Abstract

Human cytomegalovirus (CMV) infection is associated with higher risk of cardiovascular diseases in immunocompromised organ transplant patients; it has been linked with the elevated arterial blood pressure. This study aimed to find a relationship between CMV antibody titers and blood pressure elevation by using the enzyme-linked immunosorbent assay (ELISA) to measure CMV IgG levels in the serum of 60 patients with high blood pressure, in comparison to 30 healthy persons with normal blood pressure as a control. All patients and control were 25-50 years old. The results showed that CMV antibody titers were higher in those who undergo blood pressure elevation. This finding supports the hypothesis that; the common CMV infection may leads to impaired vascular function

Abstract

The objective of this study was to investigate the morphological description and histological structure of adrenal gland in Iraqi black partridge Francolinus francolinus from Iraqi environment. Twenty adult healthy birds (male and female) were used in present study. They were measured and adrenal glands were removed, measured and fixed by 10% formalin and formalin and chromate fixative then stained with rotein histochemical stain (Harris hematoxylin and eosin stain (H&E), periodic acid Schiff (PAS), Azan and Mallory stain). The partridge had a small couple of adrenal glands of yellow colour they are located in abdominal cavity nearby the margin of superior kidney lobe. These are small, ovoid glands lying just cranial to the kidneys and gonads on either side of the aorta and posterior vena cava. There was no difference in shapes between adrenal gland of male and female. There were no significantly differences in the measurement of the right and left adrenal gland of the partridge. Histologically the adrenal gland of partridge was mainly compose capsule of dense connective tissue, the thickness of capsule increased according to the different point of blood vessels and large nerve trunk, nerve cell bodies and chromaffin cell embedded in connective tissue, and the cortex is composed of three zones: zona glomerulosa, zona fasciculata, and zona reticularis, these zones were interfered with others. The cells of Zona glomerulosa were arranged in irregular ovoid clusters, the nuclei stain strongly, and the cytoplasm is less pale than that of the next zone, zona fasciculata, The secretary cells were arranged in cords, the nuclei of these cells stain strongly, and the cytoplasm looks pale due to the presence of lipid droplets. The cytoplasm of Zona reticularis stained more darkly, and contains fewer lipid droplets. However the layer of gland where interfered together without clear zone contain sinusoid capillary blood vessels extend from capsular region to medulla whih contain basophilic staining cells, with a granular cytoplasm and no stored lipid. Medullary cells were found between the large and comparatively dark cells of the cortex

Abstract

Due to the specific characteristic of porcelain, the insertion of Beryllium oxide has been studied. The basic materials and quantities were selected carefully. In this work, porcelain containing 32 wt% feldspar, 24 wt% quartz and 44 wt% clay was synthesized and beryllium oxide (BeO) (1 wt.%, 3 wt.%, 5 wt% and 7wt%) were add. The basic and new composition porcelain powders were uniaxially compacted into standard samples dimensions and fired at various sintering temperatures, 1100°C, 1300°C, and 1450°C then held for 2 hour in a furnace. The effects of sintering temperatures and beryllium oxide content on mechanical, electrical and structural properties were studied. The increasing of sintering temperature on the basic porcelain leads to an enhancement in bulk density and compressive strength. Basic porcelain which suffering lower sintering temperature (1300°C) introduces higher dielectric constant values in contrast with that suffering higher temperature (1450°C). The addition of BeO to the basic porcelain leads to decrease the bulk density and compressive strength. Porcelain with lower sintering temperature introduces higher έ values in contrast with higher temperature. The FTIR measurement show the existence of absorption at 800 cm-1 which attributable to Si-O-Si symmetrical stretching vibration band in all prepared samples. Band near 780 cm-l is attributed to the vibration of a beryllium atom moving in a tetrahedron of fixed oxygen atoms, while the absorption bands in the region 400-1500 cm-1 are due to the Be-O stretching and bending vibrations.

Abstract

Hydrogeological investigation and water budget calculation of Koi Sanjaq basin is carried out. This investigation includes the determination of the aquifer types extending through the study area and flow direction as well as aquifer hydraulic properties values. Three main unconfined aquifer types were distinguished , they are (Pilaspi), , (Bihassan-Muqdadiya and Fatha –Injana) Formations , where the flow map of the unconfined aquifers shows that the flow direction is from northern and northeastern parts towards the south and southeastern parts i.e. .Lesser Zab River. Analysis of pumping test data of 9 selected wells from unconfined aquifers show that T values range from 1.51m2/day to 64.4 m2/day revealing the great variations in the aquifer lithology, extend of fissures and fractures as well as the saturated thickness of the water bearing zones. Water balance calculations are achieved using meteorological data of three meteorological stations: Erbil, Koysanjaq and Dukan , where Mehtas model is used to calculate the water surplus values which found to be equal 203.9 mm/ year. Soil Conservation Service method (SCS) and curve number methods are adopted to determine the amount of runoff where the soil type is the most critical factor. According to the infiltration rates measured by the authors, all of the study area soil is of A group, therefore the calculated value of runoff is 128.72mm/year. Overall calculations of the water balance components shows that the groundwater recharge is 75.18 mm/year, representing 10.84 % of the total rainfall for the study area.

Abstract

The identification of a bed’s lithology is fundamental to all reservoir characterization because the physical and chemical properties of the rock that holds hydrocarbons and/or water affect the response of every tool used to measure formation properties. The main purpose of this study is to evaluate reservoir properties and lithological identification of Nahr Umr Formation in Luhais well -12 southern Iraq. The available well logs such as (sonic, density, neutron, gamma ray, SP, and resistivity logs) are digitized using the Didger software. The petrophysical parameters such as porosity, water saturation, hydrocarbon saturation, bulk water volume, etc. were computed and interpreted using Techlog software. The lithology prediction of Nahr Umr Formation was carried out by appling IPSOM technique using density, neutron, and gamma ray logs. Nahr Umr Formation in well Luhais -12 was divided into three zones based on well logs interpretation and petrophysical Analysis: Zone-A, Zone-B, and Zone-C. The formation lithology is mainly composed of sandstone interlaminated with siltstone and shale according to interpretation of density, neutron, and gamma ray logs using IPSOM technique. Interpretation of formation lithology and petrophysical parameters shows that zone-C is characterized by clean sandstone with high porosity and water saturation whereas zone –B consists mainly of alternating shale beds with siltstone and sandstone with high porosity and water saturation less than zone –C and increasing of hydrocarbon saturation but Zone –A consists mainly of siltstone and sandstone layer with some of shale beds that contains hydrocarbon

Abstract

The characterizations of reservoir require reliable knowledge of certain fundamental reservoir properties. Log measurements can define or at least infer these properties: lithology, resistivity, porosity, permeability, shale volume and water, oil, gas saturation. The current study represents an evaluation of petrophysical properties in well GA-4 for Mishrif Formation in Garraf oil field, southern Iraq. The petrophysical evaluation is based on well logs data to delineate the reservoir characteristics. The available Geophysical well logs images such as (sonic, density, neutron, gamma ray, spontaneous potential, and resistivity logs) were digitized using the Didger software. The environmental corrections and petrophysical parameters such as porosity, water saturation, hydrocarbon saturation, etc. were computed and interpreted using Interactive Petrophysics (IP) program. Lithological, mineralogical and matrix identification were estimated using porosity combination cross plots. Petrophysical properties were determined and plotted as computer processing interpretation (CPI) using Interactive Petrophysics (IP) program. Mishrif Formation in Garraf oil field is divided into three units according to the petrophysical properties: Upper, Middle, and Lower. Middle Mishrif is characterized by good porosity and high hydrocarbon saturation, which represent the main reservoir. Interpretation of well logs approved that Mishrif Formation production in well GA-4 is commercial .Middle Mishrif is characterized by free oil shows .Lithological study of Mishrif Formation shows that it consists mainly of limestone whereas mineralogy consists mainly of calcite with some dolomite.

Abstract

The aim of the current paper is to resolve the non-uniqueness in gravity interpretation through searching for singular points in the gravity field that are coincide with causative body vertices. The Absolute Second Horizontal Gradient (ASHG) method is used to locate the horizontal reference location of the body, while its amplitude could be used to define body corner depth. Intelligent use of the ASHG method could help in differentiating between basin and intrusion structures from their gravity effect and could facilitate the interpretation in forward modeling and constrain inversion modeling to maximum limit. The method is tested by using many synthetic examples with different types of shapes. A real data is used to examine the method and give a decisive result about the type and shape of the causative body.

Modified Light Stemming Algorithm for Arabic Language

Abstract

Stemming is a pre-processing step in Text mining applications as well as it is very important in most of the Information Retrieval systems. The goal of stemming is to reduce different grammatical forms of a word and sometimes derivationally related forms of a word to a common base (root or stem) form like reducing noun, adjective, verb, adverb etc. to its base form. The stem needs not to be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. As in other languages; there is a need for an effective stemming algorithm for the indexing and retrieval of Arabic documents while the Arabic stemming algorithms are not widely available. The current algorithm will perform preprocessing operations then matches the result word to Arabic patterns to get the stem of the word. This paper proposed a modified light stemming algorithm for Arabic Languages. As shown from the results, the proposed algorithm is an efficient algorithm.

Abstract

A program in Visual Basic language was designed to calculate the time interval of radio storm by predict their type at specific Local Time (LT) from Baghdad location, such storms result from the Central Meridian Longitude (CML) of system ΙΙΙ for Jupiter and phase of Io’s satellite (ФIo). These storms are related to position of Io (Io- A,B,C,D). The input parameters for this program were the observer’s location (longitude), year, month and day. The output program results in form of tables provide the observer information about the date and the LT of beginning and end of each type of emitted storm. The year 2011 was taken to apply the results within twelve month; the results of the time interval of radio storm were between (0.08h-5.41h) hours. The obtained results reveal a good agreement as compared with the results of (Radio Jove) software.

Abstract

The locations of the Moon, velocity and distance were determined through hundred years using a modified formula Meeus 1998, which is used to calculate the orbit's elements, Additionally which allows us to specify the possible date for monitoring the crescent moon. In this project we describe the orbits, orbit types and orbital elements than describe the orbit of the Moon and the perturbations effect on shape and direction of the Moon's orbit, the orbital elements effect by the all perturbation were calculated directly using empirical formula. The orbital elements of the Moon's orbit for 1326 anomalies months are calculated by our Q. Basic programs and the time variation of the Moon's orbital element with perturbations can be computed by development these programs. The results get the values of the eccentricity, semi-major axis, inclination, longitude of ascending node, longitude of perigee and the anomalistic period and there variation through many years with all perturbations. The results appear that the Moon moves under balance perturbation forces in other word, with constant mean value through many hundred years.

Abstract

In this work, watershed transform method was implemented to detect and extract tumors and abnormalities in MRI brain skull stripped images. An adaptive technique has been proposed to improve the performance of this method.Watershed transform algorithm based on clustering techniques: K-Means and FCM were implemented to reduce the oversegmentation problem. The K-Means and FCM clustered images were utilized as input images to the watershed algorithm as well as of the original image. The relative surface area of the extracted tumor region was calculated for each application. The results showed that watershed trnsform algorithm succeedeed to detect and extract the brain tumor regions very well according to the consult of a specialist doctor after viewing the resultant images. The adaptive technique, watershed based on clustered segmented image, improved the performance of the watershed transform and reduced the oversegmentation problem, and the utilizing of bilateral smoothing improves this result.
