In the current study, the Iron Aluminide FeAl was prepared using powder metallurgy technology. The mechanical properties of the compound. FeAl can be improved by adding boron and molybdenum Mo. So, adding B and Mo As a result of an increase in the compressive strength of the semi-metallic compound FeAl a compressive strength of (466.5) MPa and (415) Mpa was when adding obtained (0.3% B) and 1. 5% Mo while when adding boron and, respectively, molybdenum together with ratios 0.3% B+1.5% Mo it led to an increase in the compressive, strength to 498.3 Mpa, As for the hardness test, adding 1.5% Mo increased the hardness of the semi-metallic compound FeAl to (298.3) Mpa, which was, (260) MPa for samples without any addition, and when adding 0.3% B (the hardness value became (2681) MPa), but when adding, (0.3%) B+1.5% Mo it was found that the hardness value reaches (303) MPa. As for the sliding wear test (found that the addition of was It 1.5% Mo reduces the slip wear rate of the compound FeAl to (4*10 -10 g/Cm) as well as adding, 0.3% Reduced the slip wear rate to 110 -9 g/ Cm, while the slip wear value of the compound FeAl without any addition was (210-6 g/Cmv). The addition of 0.3% B+1.5% Mo to led to a reduction in the slip wear rate g/Cm), (3.3 * 10 -11).

The city represents a dynamic spatial organization formed by a group of inhabitants, elements and activities that are interrelated and interacted to form a special urban system. As a result of the accumulation of changes over time in urban land uses, some urban changes take place, which are reflected on changing its spatial organization and urban uses. Riverbank cities, like other cities, are spatially and interactively regulated by many effects. However, having a river as an integral part of the urban composition of the city, it has an impact on these uses and their organization over time. the research problem is exposed from this idea which is represented by the unclear functional relationship of the Euphrates River on the regulation of the land uses in the City of Samawah. The study assumes that the river has an impact on the functional relationship affecting the regulation of land uses in the city of Samawah. Using GIS, urban transformations of land use around the river in the city of Samawah have been monitored, using the multiple linear regression method, the functional relationship between the distance from the river as a subordinate variable and the land uses as independent variables is analyzed. Thus, to arrive at explanatory regression equations that reflect the effect of shifts in the organization of the spatial structure of the sample study area to achieve the research objectives. The study has concluded that the urban uses of the city of Samawah were inversely related with moving away from the river.

The overall objective of the current study was to investigate the possibilities of using Fenton oxidation (Photo-oxidation) as a mechanism of COD elimination that is available in sunflower wastewater (SWW). It’s chiefly appropriate aimed at the handling of organic, and at current, it is one of the most promising advanced oxidation skills. Precisely, rapid Fenton oxidation, which features high elimination competence, thorough reactions, insignificant subordinate contamination, etc., has led to numerous studies on by means of the Fenton reaction toward destroy COD in SWW. In investigational studies, finest experimental limits for example Fenton’s reagent, pH, temperature, Irradiation time and light intensity were determined. 98.41% and 78.29 % COD removal for photo-Fenton and Fenton process correspondingly were found. The adding of UV radiation toward the Fenton technique occasioned in improved squalor of COD elimination. Though the best irradiation time of the Fenton process was 150 min, the best reaction time of the photo-Fenton process was 120 min.

This paper proves the presentation features of chemical and mechanical aimed at action of heavy metal in produced water (PW). The Electro-catalytic (EC) is one of chemical- mechanical remained made and reflects the extent of its custom in purifying this wastewater. Throughout EC behavior, numerous operating limits were inspected, for instance titanium dioxide, rpm electrolysis time, and copper metal in produced water. The belongings of the working variables including the rpm (100-300), TiO2 concentration (10-30 mg/L), and the electrolysis time (5-15 min) by using Response surface methodology (RSM) and Minitab 17. The current and pH of the solution had remained occupied by way of 1 Amps, 3 respectively. Underneath the finest standards of the employed variables more than 98% removal of copper was found. The elective catalytic method is appropriate aimed at water contaminated by heavy metal, especially aimed at low concentrations of heavy metal in produced water.

An Al-Cu alloy developed for applications requiring an alloy of moderate strength, weldability and good resistance to sea water, it is an excellent, versatile alloy ideal for many applications. The results obtained show that the level of spring back is strongly related to the imposed boundary conditions. If he is conceivable to overcome this problem by a “practical” tool for single curvature panels, it seems more delicate for double tooling curvature. In conclusion, if the prospects offered by this type of process seem attractive, a vast campaign of digital investigations must be considered in order to define more precisely the limiting radii of curvature that can be achieved without causing problems with spillage or buckling of the stiffeners, especially for double curvature applications. The boundary conditions considered should be able to be reproduced experimentally during shaping. For high strain rate testing, the only usable method to obtain information about the distribution of strains in the specimen is the use of high-speed photography. This method is used to visualize the location of deformations and fracture and also to measure the deformations of the specimen. The use of ultra-fast photography for large-scale tests strain rates can be performed in order to qualitatively study the behavior of materials. The proposed new geometry for the specimen will be modified by the use of high-speed photography.
