Investigation of Local Weighting Materials as a Substitute To Barite In Drilling Mud Formulation
Abstract: Weighting materials are important components needed to increase the density of drilling mud in order to provide enough hydrostatic pressure to balance abnormalpore pressures. In Nigeria, millions of dollars are spent annually in importing barite to serve this purpose. However, there exists large reserves of weighting materials such as barite, hematite, dolomite, calcite, ilmenite in Nigeria hence the need to investigate the suitability of these materials as substitute for imported …

IMPACT OF HYDRATED LIME AND SBS ON HMA MOISTURE SUSCEPTIBILITY
Abstract: Abstract In recent years, many of the newly built asphalt and concrete roads in Baghdad and other Iraqi cities have broken down too soon. This has hurt the country's economy and public safety. One of the main reasons why these newly built roads break down is because of water damage. Leaking water weakens the bond between the aggregate and the asphalt, which makes it more likely that sidewalks will fall …

Application of Aqueous Two-Phase Systems in the Extraction of Bovine Serum Albumin
Abstract: Protein partitioning in an aqueous two-phase system (ATPS) has been found to be a powerful method for extracting and separating mixtures of biomolecules. In ATPS, many factors influence the partition coefficient K (which is the ratio of protein concentration in the top phase to that in the bottom phase) and the recovery percent (Rec%). Two systems of ATPS were used: first, polyethylene glycol (PEG4000)/sodium phosphate, and second, PEG4000/dextran. The behavior …
