The evaluation of left ventricle stiffness index in patients suffering from hypertension
...Show More Authors

Many diseases can produce cardiac overload, of these disease hypertension, valve disease congenital anomaly in addition to many other disease. One of the most common diseases causing left ventricle overload is hypertension. A long term hypertension can cause myocardium hypertrophy leading to changes in the cardiac contractility and reduced efficiency. The investigations were carried out using conventional echocardiography techniques in addition to the tissue Doppler imaging (TDI) from which many noninvasive measurements can be readily obtained. The study has involved the effect of hypertension on the myocardium stiffness index through the measurement of early diastolic filling (E) and the early velocity of lateral mitral annulus (Ea) from which left ventricle filling pressure can be obtained. Our aim was to investigate the changes in the myocardium index of diastolic stiffness using TDI for patients suffering from systemic hypertension. We studied 263 hypertensive patients (105 males and 158 females of average age of 54.07± 12.7) and 166 healthy subjects (age range 40.06± 12.8,53 males and 113 females) as a control group. Measurements were carried out using tissue Doppler imaging (TDI) of the mitral annulus in addition to other echocardiographic measurements for the assessment of  left ventricle end diastolic dimension (LVEDD), Doppler peak early (E) and late (A) diastolic filling velocities. Results reveal that mitral annular early diastolic velocity (Ea) measured by TDI, that (Ea) was significantly lower for the hypertensive group in comparison with the control group (Ea 9.81 ± 2.87 cm/s for hypertensive vs. 12.90 ± 2.395 cm/s for control  p value <0.001. Hypertensive group also showed a significantly higher mitral annular late diastolic velocity (Aa) in comparison with control group as Aa 11.21 ± 2.504 cm/s for hypertensive vs. 9.787 ±2.201cm/s for control, p value <0.001..  In conclusion, LV myocardial diastolic stiffness index is increased in hypertensive patients.

Biostratigraphy of the Late Cretaceous-Early Paleocene Succession in Selected Wells, Jambur Oil field, Kirkuk, Northern Iraq
...Show More Authors

The Late Cretaceous-Early Paleocene Shiranish and Aliji formations have been studied in three selected wells in Jambur Oil Field (Ja-50, Ja-53, and Ja-67) in Kirkuk, Northeastern Iraq. This study included lithostratigraphy and biostratigraphy. The Late Campanian-Maastrichtian Shiranish Formation consist mainly of thin marly and chalky limestone beds overlain by thin marl beds, with some beds of marly limestone representing an outer shelf basinal environment, the unconformable contact with the above Middle Paleocene-Early Eocene Aliji Formation contain layers of limestone with marly limestone and chalky limestone which represents an outer shelf basinal environment. Five Biozones in the Shiranish Formation were determined which are: 1

Increasing the design efficiency of roads in Al-Shatrah city center by achieving adequacy for car parking
...Show More Authors

        The research deals with the analysis of the city's commercial center using geographic information systems to solve the problem of congestion by evaluating the efficiency and adequacy of car parking lots according to local and Arab standards. Undoubtedly, the importance of car parking areas, as they are not within the desired efficiency within the city, will lead to congestion and traffic becomes very difficult. Thus, the transportation service loses its most important characteristic, which is the ease of movement. Therefore, there has become an urgent need to study and analyze it, as well as to verify the adequacy of the service, and the amount of deficit required to be provided to solve the tra

Population Dynamics of the Terrestrial - Isopod species Armadillidium vulgare Latrielle , 1804 in AL - Jadriyia District -Baghdad - Iarq .
...Show More Authors

The Present Work includes the study of the population dynamics of Armadillidium vulgare in AL- Jadiriya region in Baghdad. Monthly samples were collected using a quadrat 0.0625 m2 from November 2007 to November 2008.. The population density of A.vulgare, ranged from 880 ind/m2 in May to251 ind/m2 in January respectively. This species showed high aggregation dispersion in the study area. The sex ratio showed that the number of females were more than that of males and significantly differd (P < 0.05) during the reproductive months. Furthermore, it was found that the juveniles of species were present at most time of the year, But the large sized groups have been observed during summer and spring. And showed a positive linear correlations betwe

Abstract : A research was conducted to study the process parameters affecting hexavalent chromium Cr (VI) (carcinogenic compound) the removal percentage from the electrical industries company waste water that contain 88 mg/l of Cr (VI) concentration by adsorption onto tea wastes. Synthetic water with 88 mg/l Cr (VI) concentration was used. Several operation parameters affecting Cr (VI) removal efficiency were investigated, such as pH, initial Cr (VI) concentration, stirring time and tea wastes dose. The experimental results reveal that maximum Cr (VI) removal reached up to 94.26% at pH of 2, stirring time of 180 minute, tea wastes do

Optimization of Separator Size and Operating Pressure for Three-phase Separators in the West Qurna1 Oil Field
...Show More Authors

An optimization study was conducted to determine the optimal operating pressure for the oil and gas separation vessels in the West Qurna 1 oil field. The ASPEN HYSYS software was employed as an effective tool to analyze the optimal pressure for the second and third-stage separators while maintaining a constant operating pressure for the first stage. The analysis involved 10 cases for each separation stage, revealing that the operating pressure of 3.0 Kg/cm2 and 0.7 Kg/cm2 for the second and third stages, respectively, yielded the optimum oil recovery to the flow tank. These pressure set points were selected based on serval factors including API gravity, oil formation volume factor, and gas-oil ratio from the flow tank.    To impro
