In aryl propionic acid most common drugs are ibuprofen, ketoprophen and naproxen. These are available over-the-counter in United States. A consumer report noted that ibuprofen, naproxen, and salsalate are less expensive than other NSAIDs, and essentially as effective and safe when used appropriately to treat osteoarthritis and pain. Ibuprophen (Motrin®, Advil®, Motrin IB®) is considered to be among the safest NSAIDs and is generally well tolerated but can, nevertheless, rarely cause clinically apparent and serious acute liver. Ketoprophen (Orudis,Oruvail) topical plasters are being extensively used for treatment of musculoskeletal pain. Ketoprofen is used for its antipyretic, analgesic, and anti-inflammatory properties. Naproxen (Naprosyn®, Aleve®) is commonly used for the reduction of pain, fever, inflammation and stiffness caused by conditions including migraine, osteoarthritis, kidney stones, rheumatoid arthritis, psoriatic arthritis, gout, ankylosing spondylitis, menstrual cramps, tendinitis and bursitis.

In general, there exists virtually very little difference between the therapeutic efficacy of different NSAIDs, as certain patients would respond to one ‘drug’ better than another. In reality, it is almost difficult to predict the best suitable drug for a patient; thus, it invariably necessitates to arrive at the best-fit-drug via trial and error only. By studying these drugs we can get the knowledge about these drugs like how these drugs are useful and harmful for us.

A striking inter-relation has been evolved for heats of formation determination of ternary chalcopyrite of the type AIBIIIC2VI. The proposed relation is derived in terms of average inter-atomic distance and melting temperature. A discussion has also been presented among the heats of formation, average inter-atomic distance and melting temperature of these compounds.

Keywords: Chalcopyrite, Average inter-atomic distance, Melting temperature and Heats of formation.

Due to the economic burden imposed by deregulation, utilities are looking at new ways of operating and maintaining their assets. The utilities are concentrating at managing their substation assets. Financial managers try to maximize return-on-investment for each asset; substation maintenance managers try to maximize the value of each task. By minimizing unexpected breakdowns, we maximize return on capital investment. Asset criticality, reliability, and condition assessment plan key roles in helping to manage risk. By conducting reliability cantered maintenance as an overall strategy for critical asset management, a powerful enterprise system, like Meridium, bring together the information from across the enterprise to make effective decisions.

Keywords: RCM (Reliability Centered Maintenance), Deregulation, FMEA (Failure Mode and Effect Analysis), PM (Preventive Maintenance) and MTBF (Mean Time between Failure).

MHD flow of a dusty Oldroyd B_ liquid through a porous medium between two parallel plates inclined to the horizon has been studied. The liquid velocity, dust particle velocity and flux of flow have been obtained. Results of several authors have been deduced as particular cases of the present investigation. The physical situation of motion has been discussed.

Keywords: Oldroyd B liquid, Porous medium, Laminar flow.
