Tectonic activation and the risk of Ilisu Dam collapse to Iraq through modelling and simulation using HEC-RAS
...Show More Authors
Abstract<p>Floods caused by dam failures can cause huge losses of life and property, especially in estuarine areas and valleys. In spite of all the capabilities and great improvements reached by man in the construction of dams and their structures, they will remain helpless before the powerful forces of nature, especially those related to tectonic activation, and the occurrence of earthquakes of different intensities.</p><p>The region extending from the Ilisu Dam in Turkey to the Mosul Dam in Iraq was chosen as an area for this study, and the HEC-RAS application was used to simulate the collapse of the Ilisu Dam due to a major earthquake, to know the magnitude of the risks and losses that could result from this. The Ilisu Dam was built very close to a highly tectonically active fault system, particularly the East Anatolian Fault (EAF), which is one of the largest tectonically active faults in the world with a length of 500 km. This region has witnessed past and present earthquakes of high magnitude (M > 7), especially in the EAF, so the construction of the Ilisu Dam near the EAF fault system is of great concern, as it was built in a basin with very complex seismic activity and geology.</p><p>Using the HEC-RAS simulation application, the study found that the flood resulting from the collapse of the Ilisu Dam would reach the edges of the Mosul Dam Lake in just 13 h. With a flow of more than 100,000 m<sup>3</sup>/s, more than 10 billion m3 of water will flow into the Mosul Dam Lake within four days of the disaster. This will lead to the collapse of the Mosul Dam and direct the flood wave of the collapse of these dams towards Baghdad through Mosul, Tikrit, and Samarra. This could pose risks to all Iraqi cities located within the Iraqi sedimentary plain (Mesopotamia), from south of the Mosul Dam up to Basra, in a scenario similar to Noah’s Flood.</p>

Flow Injection Spectrophotometric Technique for Determining of Genistein in Pure and Supplements Formulations Through Diazotization Coupling Reaction
...Show More Authors

Genistein (GEN) is The major isoflavone found in soybeans, has a number of cardiovascular health benefits, Postmenopausal syndrome and osteoporosis. A direct flow injection analysis method for estimation of (GEN) in pure and supplements formulation . This system is based on diazotization coupling reactions between procaine penciline (PR) and genistein in basic medium, they formed yellow dyes have maximum absorption at 416 nm. Calibration curve were constructed over different GEN concentrations, linearity for GEN was 10-100 µg.mL-1 and detection limits of 1.51 ?g/mL. In the FIA technique, all analytical factors were analyzed and optimized. The established method was successfully used to determine GEN in the formulations of its supplement

Impact of Brand Capital on the Stock Price Crash Risk, an Empirical Study
...Show More Authors

The factors influencing the financial market are rapidly becoming more complex. The impact of non-financial factors on the performance of a company’s common stock can increase in ways that were not previously expected. This study investigated how brand capital affects the risk of stock prices in Iraqi private banks listed on the Iraq Stock Exchange failing by identifying the likelihood of a crash caused by a negative deviation in the distribution of returns on ordinary shares. As a result, the current study’s concept is to review an analytical knowledge framework of the nature of that relationship, its changes, and its impact on the pricing of ordinary shares of the banks of the researched sector for the years 2009 to 2017, as w

The Accumulation Risk of Heavy Metals in Vegetables which Grown in Contaminated Soil
...Show More Authors

The present study has been carried out to estimate heavy metals mobility, bioconcentration and transfer from polluted soil to roots tissues and from roots tissues to aerial parts using bioconcentration factor and translocation factor. Soil samples and the biomass of the eight vegetable species have been collected during summer season, 2019 from four different sites in Wadi Al-Arg, Taif Governorate, KSA. In general, heavy metals content of soil samples in site III and IV have recorded elevated values compared with those of site I and II. The soil from site IV has shown the highest concentration of Mn, Ni, Cr, Pb, Cu, and Cd amounted 31.63, 14.05, 13.56, 22.79, 31.02 and 2.98 mg/kg dry soil respectively, while the soil from site III has sh

Preparation Activated Carbon from Scrap Tires by Microwave Assisted KOH Activation for Removal Emulsified Oil
...Show More Authors

In this paper activated carbon adsorbents produced from waste tires by chemical activation methods and application of microwave assisted KOH activation. The influence of radiation time, radiation power, and impregnation ratio on the yield and oil removal which is one of the major environmental issues nowadays and considered persistent environmental contaminants and many of them are suspected of being carcinogenic. Based on Box-Wilson central composite design, polynomial models were developed to correlate the process variables to the two responses. From the analysis of variance the significant variables on each response were identified.  Optimum conditions of 4 min radiation time, 700 W radiation power and 0.5 g/g impregnation ratio

Secure Image Steganography Through Multilevel Security
...Show More Authors

The concealment of data has emerged as an area of deep and wide interest in research that endeavours to conceal data in a covert and stealth manner, to avoid detection through the embedment of the secret data into cover images that appear inconspicuous. These cover images may be in the format of images or videos used for concealment of the messages, yet still retaining the quality visually. Over the past ten years, there have been numerous researches on varying steganographic methods related to images, that emphasised on payload and the quality of the image. Nevertheless, a compromise exists between the two indicators and to mediate a more favourable reconciliation for this duo is a daunting and problematic task. Additionally, the current

Determination of Elastic Moduli and Geotechnical Parameters of the Upper Soil Layer Using Ultrasonic Waves in Al- Jadiriyah Area - University of Baghdad-Iraq
...Show More Authors

Analysis and determination of some of the elastic moduli and other geotechnical parameters in the campus of the University of Baghdad performed by using New Sonic Viewer in the field to measure (Vp) and (Vs) velocities as well as the density of the upper soil inside the campus. Seventeen profiles were selected each of (10) m. length distributed randomly inside the university campus to evaluate the top soil properties in addition to the soil profile.
The ultrasonic waves showed two layers of the soil with different velocities of
(Vp) and (Vs). The velocities of p-wave of the first layer ranged from (288-642) m/sec. On other hand the velocities of shear wave (Vs) in the same layer ranged from (88-193) m/sec. In the second layer the v

Radionuclides content and the radiological hazard of sediment of the Euphrates River and sprigs-western Iraq
...Show More Authors

Sediments samples from ten stations along the Euphrates River and seven
samples from selected springs within Al –Anbar governorate, (western part of Iraq),
were collected and analyzed for radioactivity. Sediments samples were dried at 100
ºC for 24 hours. Radioactivity in 1 kg of each sample was measured using gamma
spectrometer system based on a pure germanium detector with efficiency 30%. The
activity of Ra-226, Th-232, K-40 were measured to be within the typical average of
the radioactivity in sediment in world rivers, while relatively elevated concentration
were found in the sediment of some of the studied spring. In current study activity
concentrations of Cs-137 in the sediments were detected which may be
