In this study, sodium silicate was successfully synthesized from silica rich sand located at the western desert of Iraq. After the pretreatment silica sand, it was characterized using X-Ray Fluorescence (XRF). The results indicate that the sand had 84% silica from total metal oxides percent of 87.7%. Sodium silicate was prepared from the silica sand using dry fusion method. The effect of (NaOH/sand) ratio of (1:1, 1.2:1, and 1.4:1) at different fusion temperatures of (400,500, and 600)0C was studied. For comparison commercial sodium silicate obtained from Aldrich was used. All prepared samples
The use of Information and Communication Technology tools for registering and administering examinations had helped in attaining efficiency and error-free results and computation. This research developed a secured computer-based testing system with resumption capability module. The designs were implemented using HTML, PHP, MySQL, and JavaScript platforms. The system was tested locally using WAMP and was found to be effective in reducing the problem of authenticity (especially with the Fingerprint Mechanism embedded), and facilitated the resumption capability in the case of failure using the te
Major challenges encountered when drilling in the last hole in Noor field due Shale problems (sweeling, sloughing, washout, …) which are often caused by Incompatibilities of drilling fluids and shale, In Tanuma formations most of the drilling problems occur in the last hole because of the high concentration of shale about 85% (Ahmed K. Abbas,2018), This shows that selecting appropriate drilling mud is important when drilling through a shale formation. Compared with Non-inhibitive fluids, the inhibitive fluids have advantages such as resistance to Swelling, resistance to Collapse, being good
Brain stroke occurs because of blockage in the artery which deliver oxygenated blood to the brain. Acute Ischemic Stroke (AIS) is mostly occurred brain stroke. Early detection of brain stroke can be life saving for patient. For study of brain tumor detection and segmentation, MRI Images are mostly used in recent years. Due to MRI Images we can detect the brain tumor. A brain MRI can help to analyze bleeding, tumors, infections, damage from an injury or a stroke, or problems with the blood vessels inside the brain. Using the proposed algorithm, automatic brain stroke detection is possible in th
The aim of this paper is to study and evaluate various operational variables, including gas mixture flow rate, nanomaterial type and concentration and circulating absorbent solution flow rate by using a PTFE hollow fiber membrane contactor with a potassium carbonate solution containing titanium dioxide and silica nanomaterial as additives to separate carbon dioxide from CO2/N2 mixture. The results indicate that the CO2 removal efficiency at 0.5 wt.% titanium dioxide (50 nm), significantly increased from 38% to 70%, while absorption flux increased from 2.024×10-3 to 3.627×10-3 (mole /(m2. s))
