Lubricant A lubricant is a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles. The property of reducing friction is known as lubricity. Lubricant is a material that reduces the friction arising due to the sliding / gliding / rolling / moving of two different components in a machinery. Friction is an undesirable process that results in (i) wear and tear of the surfaces of the moving parts (ii) loss of enormous energy as

5. POTASSIUM PERMANGANATE Potassium permanganate (KMnO4) is used primarily to control taste and odors‚ remove color‚ control biological growth in treatment plants‚ and remove iron and manganese. In a secondary role‚ potassium permanganate may be useful in controlling the formation of THMs and other DBPs by oxidizing precursors and reducing the demand for other disinfectants (Hazen and Sawyer‚ 1992). The mechanism of reduced DBPs may be as simple as moving the point of chlorine application further

1 INTRODUCTION In recent years‚ there has been rapid growth in the number of Fast Dissolving / Disintegrating Tablet (FDT) product on the market. Fast Dissolving Tablets are solid tablets and designed to dissolve/disintegrate in the patient’s mouth within a few second or minutes‚ without the need to drink or chew. However‚ the fear of taking solid tablets and the risk of choking for certain patient populations still exist despite their short disintegration/dissolution times. However‚ some

------------------------------------------------- Abstract In the last few decades‚ membrane technology has been a great attention for gas separation technology especially for natural gas sweetening. The intrinsic character of membranes makes them fit for process escalation‚ and this versatility could be the significant factor to induce membrane technology in most gas separation areas. Membranes were synthesized with various materials which depended on the applications. The fabrication of polymeric
