These components' bioaccumulation as exposure have been related to a range of illnesses and cancer, and the mechanical and physical properties of soil are altered. The "Microbial Induced Calcite Precipitation" is an environmentally green, friend, and sustainable method. This review focused on the metal remediation technology's effects and how to make them sustainable and more environmentally friendly. Many bacteria produce urease, the bacillus is a more common type. Bacteria, with sizes ranging from 0.5 to 3.0µm, are the most common microbes found in soils. It is critical to examine the type of soil, Bacterial size, and size of pore throat. The calcium carbonate majority tends to coat the surface of soils with coarse particles in the state of the contact points in soils with particles smaller than bacterial size (heterogeneous and limited precipitation). The bacterial concentration appears to affect crystal shape, calcium carbonate formation, and the cementation effect of geomaterials. Calcite precipitation takes place most when the pH is between 7.5 and 9.5. Calcite is formed three times at 50°C, while the unconfined compressive strength is only 60% of that at 25°C. Calcium carbonate can be immobilized or formed into undissolved compounds by binding free ions to the calcium carbonate's surfaces, resulting in a form of non-toxic and chemically stable.</p> Zahraa Samer Hadi, Khitam Abdulhussein Saeed Copyright (c) 2022 https://creativecommons.org/licenses/by/4.0 https://jeasd.uomustansiriyah.edu.iq/index.php/jeasd/article/view/1571 Fri, 01 Jul 2022 00:00:00 +0000 DESIGN OF A DUAL-BAND REJECTION PLANAR ULTRA-WIDEBAND (UWB) ANTENNA https://jeasd.uomustansiriyah.edu.iq/index.php/jeasd/article/view/1572 <p>This article discusses a small Ultra-wideband fixed radio wire with two score channels. Spaces are embedded into the fix of the receiving wire to give WiMAX and WLAN recurrence band dismissal. The radio wire is displayed with the economically accessible CST Microwave Studio apparatus. The opening size is steadily changed and tuned to get the ideal band dismissal reactions. The gathered outcomes show that the radio wire capacities are admirably across the whole operational frequency spectrum (3.1 GHz to 10.6 GHz), with the exception of the notched WiMAX (3.3-3.7 GHz) &amp; WLAN (5.1-5.8 GHz) bands. Additionally, the antenna was built &amp; the simulation results were gathered.</p> Sahar K. Hassan, Adheed H. Sallomi, Musa H.

The main advantages of the proposed array configuration are that it requires no isolation/decoupling circuit between the elements of the MIMO array. The suggested antenna has an impedance bandwidth of (3.1_10.6) GHz. The antenna dimension is (25×58×1.6) mm<sup>3</sup>. It is based on a simple patch antenna configuration with a simple hexagonal radiator and partial ground. The partial ground is used to improve the reflection coefficient and isolation. A 16.54mm x 9mm ground plane is used. Each element was fed through a 50Ω microstrip transmission line (MTL). The suggested antenna is polarized linearly. It performs admirably at 10.46 GHz, with a gain of 1.77dB, a reflection coefficient of 28.42dB, VSWR approx 1, an envelope correlation coefficient very close to 0 dB, a diversity gain of 10dB, and isolation of 50.44dB, respectively, and suggested antenna's diversity characteristics, such as ECC and diversity gain, are also modeled.</p> Rasha Basil Nassir, Ali Khalid Jassim Copyright (c) 2022 https://creativecommons.org/licenses/by/4.0 https://jeasd.uomustansiriyah.edu.iq/index.php/jeasd/article/view/1573 Fri, 01 Jul 2022 00:00:00 +0000 EFFECT OF METAL WIRE MESH ON TENSILE, COMPRESSION AND WATER ABSORPTION FOR BLEND POLYMER https://jeasd.uomustansiriyah.edu.iq/index.php/jeasd/article/view/1574 <p>This work aims to enhance the polymeric composite properties by adding Iron wire mesh (Fe) and aluminum wire mesh (Al) as reinforcement materials with various ratios. A polymer blend of the [epoxy (EP)+ polyester (UPS)] as matrix material has been utilized. The hand layup approach has been utilized for manufacturing castings. Epoxy and polyester have been mixed with different volume ratios, involving (95:5,90:10, 85:15,80:20, and 75:25 Vol.%) of (epoxy: polyester). The blend was reinforced with metal mesh with volume fractions (5,10,15, and 20%). The results show the best ratios of ultimate tensile strength are (95% epoxy + 5% unsaturated polyester), and tensile strength and young modulus increase with increased volume fraction of metal mesh. The best compressive strength (CS) value was obtained for a sample of (95% epoxy +5% unsaturated polyester). The compressive strength increased with the increased volume fraction of iron mesh but reduced with the used aluminum wire mesh. Also, water absorption increased with increased unsaturated polyester, iron mesh, and aluminum mesh percentage.</p> Akram Q. Moften, Ismail I. Marhoon, Yasir K.

Slurry Infiltrated Fiber Concrete (SIFCON) is a special kind of Fiber Reinforced Concrete (FRC). The purpose of this research is to study the influence of SIFCON on the torsion behavior of reinforced concrete beams. In the experimental program, five beam specimens are cast and tested under pure torsion. Two of them were from normal concrete as a reference, two from SIFCON with a steel fiber volume of 10% and the last beam was normal concrete strengthening by SIFCON with a steel fiber volume of 10%. The results have indicated enhancement in an ultimate torsional moment of SIFCON beams when compared with the reference, normal concrete beam. In addition, by reducing the twist angle and increasing torsional stiffness, the resistance moment of torsion was improved.</p> Zahraa Mohammed khalifah, Mohammed Mohammed Rasheed Copyright (c) 2022 https://creativecommons.org/licenses/by/4.0 https://jeasd.uomustansiriyah.edu.iq/index.php/jeasd/article/view/1575 Fri, 01 Jul 2022 00:00:00 +0000 EFFECT OF THE GAIT SPEED ON A NEW PROSTHETIC SHANK BELOW KNEE https://jeasd.uomustansiriyah.edu.iq/index.php/jeasd/article/view/1576 <p>One of the most important problems that the components of the prosthetic limbs suffer from; is the increase in walking speed leads to an increase in the ground reaction force. In this research, a new shank was designed and manufactured using the porous functionally graded materials by a 3D printer of PLA material, and to ensure the success of this shank, several tests were conducted on it, including to know the mechanical properties, as well as the life test by a special device that was manufactured. A test was conducted to know the life of the shank when normal walking (about 1.35 m/sec) and running ( about 6 m / sec ), and it was found that this shank was successful and did not fail in that test, the prosthetic foot ( type SACH) failed before it at normal speed and high speed.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</p> Zainab H.

The algorithm is produced by integrating of two other algorithms namely, electromagnetism like (EML) and differential evolution (DE) algorithms. DEIM enhances the mutation step of the original DE by using the attraction-repulsion principle found in the EML algorithm. Meanwhile, a novel strategy based on adjusting mutation and crossover rate factors for each iteration is adopted in this paper. The implemented scheme's success is confirmed by comparing its results with those obtained by techniques cited in the literature. Along with the results, the DEIM suggests high closeness with the experimental I–V characteristic. For the proposed algorithm the average Root Mean Square Error ( MSE), Absolute Error (AE ), Mean Bias Error ( MBE), and execution time values were 0.0608, 0.044, 0.0053, and 23.333, respectively. The comparisons and evaluation results proved that the DEIM is better in terms of precision and rapid convergence. Furthermore, fewer control parameters are needed in comparison to EML and DE algorithms.</p> Mawj M. Abbas, Dhiaa H.

Has been used the OGAWA SEIKI Ltd apparatus and applied to these samples to predict the behavior of the alum in the treatment process. Physiochemical analyses were achieved on samples before and after treatment to stand on the ability of success. These tests have been achieved according to The experimental tests of characteristics were done as stated by American Public Health Association (APHA), American Water Works Association (AWWA), and Water Environment Federation (WEF). Results showed that behind the high removal, and efficiency is many mechanical terms of coagulation, perhaps the most prominent of which is the scavenging mechanism. The effectiveness of the aluminum ion is at a certain limit, in limited pH, an increase in the concentration of this ion means an increase in the concentration of the positive charge and getting the inverse effect. due to the wide capacity of aluminum ions to make bonds by combining with negative roots, it has been noticed the percentage removal of phosphorus reached up to 95%. These compounds create aluminum phosphorus flocs. &nbsp;The aluminum phosphorus compounds have gelatinous properties that could make enmeshment and attract different particles and then settle in the bottom.</p> Al A.
