...Show More Authors

Inundation floodingmap aimedto find outearly warningsto avoidenvironmental damageandhumanin terms of theheight ofthe wave ofwater, speed time arrival, effects of inundation sideanddepth of the water/ distanceand reduce the impact of the flood wave after obtaining the process of collapse of the dam in the lower part of the river to the dam area. The study has been using a numerical model one-dimensional depends on the development of equations (Saint-Venant) so that parts of the river, any river channel main banks of the right and left treated as separate parts, that’s the difference in the characteristics of the hydraulic and engineering, along the line of the flow will take into account in each section of the sections and flow in the river valley. Throughapplied numerical model of the Nile River in the area between the Roseires dam and Khartoum is distance (630 km) south of Khartoum , to get a jest analysis of the impact of a wave of flooding in the river on the following parameters : the maximum discharge , the maximum of attributed, as underdevelopment of the discharge maximum , and the time defaults to the maximum level and the surface area on the banks of the river and its extension and different values of the coefficient of manning roughness to the banks of the river. Eight scenario have been prepared for the flood wave read to compare the effect amount of water flow in the channel resulting from the collapse of the dam was resulting of Roseires dam , eight scenario to represent the five and extract the resulting values of Inundation map to cities located on the downstream of the dam.Thefive scenarioswerecalculated by using (HEC-RAS 4.1.0), (HEC-GeoRAS)a GIS programs and the flood wave resulting from the collapse of the Roseires dam to compare the results showed that the scenario NO. 5 is the best scenario result from the collapse makes sense due to the form of the disposal of the flood wave resulting from the collapse of the Roseires dam and then get overtopping from Sennar dam to the inability of the reservoir and dam to stop the flood wave. The results also indicate that the time needed to reach the greatest discharge of the flood wave resulting from the collapse of the Roseires dam to the city of Khartoum is ( 4, 6, 7and 9 ) day on the cities ( Roseires , Sennar , Wad Medani and Khartoum ) respectively, of the cases . The maximum height of the flood wave reaching the city of Khartoum has given the scenario NO. 5 by height wave (3-50) meters respectively. As well as the delay in the arrival time of the maximum height of the flood wave to the city of Khartoum is one day for the five scenarios compared to the other. The Inundation map development resulting from the collapse of the Roseires dam and get the flow overtopping the Sennar dam, arrival to Khartoum, was determined the surface area of the affected river and both banks of the depth of the wave and latency along the river has been selected four major cities along the river which Roseires,Sennar, Wad Medani and Khartoum.

Spatial Distribution of Heavy Element in Erbil's Municipal Landfills by Using GIS
...Show More Authors

Untreated municipal solid waste (MSW) release onto land is prevalent in developing countries. To reduce the high levels of harmful components in polluted soils, a proper evaluation of heavy metal concentrations in Erbil's Kani Qrzhala dump between August 2021 and February 2022 is required. The purpose of this research was to examine the impact of improper solid waste disposal on soil properties within a landfill by assessing the risks of contamination for eight heavy elements in two separate layers of the soil by using geoaccumulation index (I-geo) and pollution load index (PLI) supported. The ArcGIS software was employed to map the spatial distribution of heavy element pollution and potential ecological risks. The I-geo values in summe

Immunohistochemical study of CD34 in tooth eruption by using amniotic stem cells
...Show More Authors

Background: Tooth eruption is a more general process, however, which includes certain posteruptive tooth movements. There are two fundamental requirements for both tooth eruption to occur: (1) Require soft tissue, intervening between tooth structure and alveolar bone, which plays an important role in regulating the remodeling of adjacent tissues. (2) Require bone turnover that is temporally and spatially regulated to facilitate specific translocations of teeth through alveolar bone These amniotic stem cells are multipotent and able to differentiate into various tissues, which may be useful for human application and recently it used in many medical branches. CD34 is an endothelial marker that is extensively used in immunohistochemistry a

Turbid of Water By Using Fuzzy C- Means and Hard K- Means
...Show More Authors

In this research two algorithms are applied, the first is Fuzzy C Means (FCM) algorithm and the second is hard K means (HKM) algorithm to know which of them is better than the others these two algorithms are applied on a set of data collected  from the Ministry of Planning on the water turbidity of five areas in Baghdad to know which of these areas are less turbid in clear water to see which months during the year are less turbid in clear water in the specified area.

Furfural Degradation in Waste Water by Advanced Oxidation Process Using UV/H2O2
...Show More Authors

Furfural is one of the one of pollutants in refinery industrial wastewaters. In this study advanced oxidation process using UV/H2O2 was investigated for furfural degradation in synthetic wastewater. The results from the experimental work showed that the degradation of furfural decreases as its concentration increases, reaching 100% at 50mg/l furfural concentration and increasing the concentration of H2O2 from 250 to 500 mg/l increased furfural removal from 40 to 60%.The degradation of furfural reached 100% after 90 min exposure time using two UV lamps, where it reached 60% using one lamp after 240 min exposure time. The rate of furfural degradation k increased at the pH and initial concentratio

Energy Saving of Heat Gain by Using Buried Pipe Inside a Roof
...Show More Authors

Abstract

    This work deals with a numerical investigation to evaluate the utilization of a water pipe buried inside a roof to reduce the heat gain and minimize the transmission of heat energy inside the conditioning space in summer season.     The numerical results of this paper showed that the reduction in heat gain and energy saving could be occurred with specific values of parameters, like the number of pipes per square meter, the ratio of pipe diameter to the roof thickness, and the pipe inlet water temperature. Comparing with a normal roof (without pipes), the results indicated a significant reduction in energy heat gain which is about 37.8% when the number of pipes per m

Comparison of HF and HCl Chemical Laser Parameters by using Mathematical Model
...Show More Authors

A simplified theoretical comparison of the hydrogen chloride (HCl) and hydrogen fluoride (HF) chemical lasers is presented by using computer program. The program is able to predict quantitative variations of the laser characteristics as a function of rotational and vibrational quantum number. Lasing is assumed to occur in a Fabry-Perot cavity on vibration-rotation transitions between two vibrational levels of hypothetical diatomic molecule. This study include a comprehensive parametric analysis that indicates that the large rotational constant of HF laser in comparison with HCl laser makes it relatively easy to satisfy the partial inversion criterion. The results of this computer program proved their credibility when compared with th

Removal of Water Turbidity by using Aluminum Filings as a Filter Media
...Show More Authors

The ability of using aluminum filings which is locally solid waste was tested as a mono media in gravity rapid filter. The present study was conducted to evaluate the effect of variation of influent water turbidity (10, 20and 30 NTU); flow rate(30, 40, and 60 l/hr) and bed height (30and60)cm on the performance of aluminum filings filter media for 5 hours run time and compare it with the conventional sand filter. The results indicated that aluminum filings filter showed better performance than sand filter in the removal of turbidity and in the reduction of head loss. Results showed that the statistical model developed by the multiple linear regression was proved to be
valid, and it could be used to predict head loss in aluminum filings
