Synthesis and properties of polyacrylamide
Polyacrylamide (PAM)-encapsulated clay nanoparticles (NPs) were successfully synthesised by conventional emulsion polymerisation for solving the aggregation matter of nanoscaled clay. A novel nanofluid based on PAM has been developed and its’ attributes have been experimentally tested as an optimised solution. The frequency, sonication time effect, NPs and polymer concentration on the

Effect of Surfactant and Hydrophobe Content
Associating polyacrylamide polymers have found profound use in the oil industry for Enhanced Oil Recovery (EOR) due to their improved rheological properties compared with ordinary non-associating polymers. Polymer rheology is important as it controls the mobility ratio of the displacing fluid to the displaced fluid and this can be severely affected by the high temperature and salinity present

Effect of Surfactant and Hydrophobe Content
In this project, polyacrylamide containing N-dodecylacrylamide was synthesized via micellar copolymerization in order to investigate the effect of hydrophobe variation and surfactant variation on
This associative polymer can be used for acid diversion and water control, and has been widely used in Saudi Arabia , , , , , , , , . The works mentioned above primarily focus on a pH range in which the hydrogen ion concentration is less than 10 −1 mol/L; however, acidizing stimulation often involves hydrochloric acid concentrations of up to
The Effect of Hyrolysis of Polyacrylamide on Solution
The polyacrylamide flow in porous media. The degree of mobility reduction is proportional to: 1. the viscosity of the polymer solution which is greatly affected by the presence of dissolved ions in the water, and . 2. the reduction in reservoir permeability to water caused by flow of the polymer solution.

Therapeutic Effects of Fig Tree Latex on Bovine Papillomatosis
The effects of fig tree latex in treating teat papillomatosis in cow in comparison with salicylic acid were evaluated. For this purpose, 12 cows of 1–3 years of age (average 2.25) affected by
Nineteen soil samples were collected from five locations in Qassim region, Saudi Arabia to isolate native strains of B. thuringiensis and chitinolytic bacterium (Bacillus subtilis).
