Removal of Nitrate from Groundwater by Using Effective Microorganisms (EM)
Authors: Ali Mohamed Burhan 
Published: June 2022

In this research, the ability of effective microorganisms (EM) to remove nitrate from groundwater had been studied. Many samples were taken and tested from several wells in Tikrit University. The tests showed that the samples of groundwater contained a few nitrate concentrations (less than 1 mg/l) so that the wastewater was a synthetic solution by adding potassium nitrate (KNO3) to the groundwater as a nitrate source within the range of (50–150) mg/l. the ratios of EM were used in the experiments ranged between (1:250) to (1:5000). While the hydraulic retention times 24 and 48 were used in the experiments. The result showed that the removal efficiency of nitrate was increased by increasing the ratio of EM in the processing unit and the maximum nitrate removal was 82% when the nitrate concentration and EM ratio were 150 mg/l and (1:250) respectively and HRT was 48 hr.

Published: June 2022

In steam power plants, and high pressure high temperature water flow, phase change takes place resulting in bubbly flow. Such flow causes vibration and noise in the conduits. The present study emphasized on cavitations during a dual phase flow (water- vapor) with a variation of velocities at different conditions in converge-divergence nozzle. The investigation was carried out experimentally and numerically, by CFD simulation. A transparent material is used of PMMA in order to visualize the various regions of the flow. Furthermore, the effect of flow velocities on vibration and noise was evolved in the experimental measurements. The CFD simulation model of this problem is defining a dual compressible viscous flow with k-epsilon model for the turbulence modeling. The analyses of the simulation results and the experimental observation have been seen to be comparatively conscionable in the cavitation zone and the estimation of the throat pressure cavitations during a dual phase flow with a variation of mass transfer conditions. A model were combined with a linear viscous turbulent model for the mixed fluids in the computational fluid dynamics software. A CFD Code with modified user intervention is used to simulate steady cavitation. Some of the models were also tested using a three dimensional -CFD code in configurations of cavitation on three-dimensional a converge-diverge sections. The pressure distributions and volume fractions of vapor at different cavitation numbers were simulated, which agreed well with experimental data.

Published: June 2022

Water quality degradation in the Tigris River would occur in the last two decades since pollutant loads from agriculture drainages, municipal wastewaters, and industrial wastewaters are not envisaged to be handled effectively. This will face the problems of water quality status which is used for multiple purposes, and drinking is one of these. This study used the Bhargava Water Quality Index (WQI) method as a tool to assess the water quality status of Tigris River as a source of raw water for water treatment plants within Salah-Alddin Province. For this purpose, six sectors along the mainstream were chosen to take water samples from January 2010 until December 2010. The study had shown that the stream WQI lies between 2nd class (good -84.31) to 5th class (poor – 39.73). Decline of WQI values had appeared in all sectors in (January and February 2010) and improved after February 2010. The median values of WQI for Balad sector were the lowest in comparison with other sectors due to the effect of human, animal and agricultural activities, whereas, the median values of WQI for Al-dour sector was the highest because the strong hydraulic mix in addition to high water velocity.
A Contourlet-Based Image Denoising Technique with Coefficient Threshold Level Estimation
Authors: Dawood Akram A. 
Published: June 2022

In this paper, a new image denoising technique is proposed based on contourlet transform. Many random images are generated simulating the standard deviation level of the original noisy image and the contourlet threshold level is then calculated based on such simulations. Different contourlet coefficients are thresholded by such precalculated contourlet thresholds indicating a nonlinear thresholding manner. The resulting denoised images posses the superiority of the proposed technique over three other recents. Subjective and objective measurements of the proposed technique support such superiority.

Published: June 2022

Conservation of natural resources and rapid urbanization has prompted growing demand for natural aggregate by construction industry. This demand is compounded by considerable decline in the availability of good quality natural aggregate and enormous increase in quantities of demolished concrete. This report presents a study of mechanical properties of concrete made by using the demolished concrete as coarse aggregate in addition to steel fibers.. In the concrete mixes the ratios of concrete aggregate range from 0% to 100% with the increment of 25% the ratio of steel fiber was 6% of whole mix volume. Three concrete mixes have been prepared with proportion of 1:2:4, the water cement ratio was 0.5. The essential mix was control mix without steel fiber for comparison, the other mixes with or without steel fibers with different proportion of recycle concrete aggregate. The mixes were casted in standard specimens, cylinders and cubes and tested under static loading The specimens were tested for compression strength and splitting tensile strength. This research shows that increasing recycle concrete aggregate will decrease the compressive strength and splitting tensile strength but adding steel fibers will increase these strengths. The recycled concrete aggregate with steel fiber are found to make a good quality concrete therefore recycle concrete aggregate can be used successfully for structural concrete instead of natural aggregate .

Published: June 2022

Rheumatoid Arthritis (RA) is a chronic disease that requires sufferers to have self-adherence in carrying out treatment. Unfortunately, initial interviews with RA sufferers showed that there were still many of them who lacked self-adherence, which resulted in the worsening of their health condition. This study aims to improve self-adherence RA patients through the Theory of Planned Behavior (TPB) framework which is designed to be an outreach activity. The counseling is carried out in one day and is divided into 3 sessions, each session having a duration of 20 to 40 minutes. Participants in the study were 12 members of the Sahabat Rheumatoid Arthritis (SAHARA) community who were RA sufferers as well as agents of change for other RA sufferers who had not yet joined the community. The results showed that the participants experienced a significant increase in self-adherence (p = 0.005 < 0.05). These results prove that counseling activities designed using the Theory of Planned Behavior framework can increase self-adherence of Rheumatoid Arthritis sufferers in undergoing treatment. Rheumatoid Arthritis (RA) adalah salah satu penyakit kronis yang membuat penderitanya harus memiliki kepatuhan diri dalam menjalankan pengobatan. Sayangnya wawancara awal kepada penderita RA menunjukkan bahwa masih banyak diantara mereka yang kurang memiliki kepatuhan diri sehingga berimbas pada semakin parahnya kondisi kesehatan mereka. Penelitian ini bertujuan untuk meningkatkan kepatuhan diri penderita RA melalui kerangka kerja Theory of Planned Behavior (TPB) yang di rancang menjadi sebuah kegiatan penyuluhan. Penyuluhan tersebut dilaksanakan dalam satu hari dan terbagi menjadi 3 sesi yang masing-masing sesinya memiliki durasi 20 hingga 40 menit. Partisipan dalam penelitian adalah anggota komunitas Sahabat Rheumatoid Arthritis (SAHARA) berjumlah 12 orang yang merupakan penderita RA sekaligus agen perubahan bagi penderita RA lainnya yang belum tergabung dalam komunitas. Hasil penelitian menunjukkan bahwa partisipan mengalami peningkatan kepatuhan diri yang signifikan (p 0.005 < 0.05). Hasil tersebut membuktikan bahwa kegiatan penyuluhan yang dirancang menggunakan kerangka kerja Theory of Planned Behavior mampu meningkatkan kepatuhan diri penderita Rheumatoid Arthritis dalam menjalani pengobatan.
