Materials which are used in making of effervescent Tablets are hydroxy-methylcellulose HPMC. For the buoyancy sodium bicarbonate is used. Initially for the selection of formulation Definitive screening design is used which allows to study the effect of large number of factors in relatively small experiment. The optimized formulation is tested for release rate, buoyancy, hardness, thickness, floating time, swelling study and release rate. These studies shows that optimized tablet remains in stomach for 24h and shows release rate of 91% which is very desirable.

This algorithm was motivated by the limited bandwidth that is available in the media that are used for wireless communications. It borrows most of the advantageous concepts from DSR and DSDV algorithms. The on demand route discovery and route maintenance from DSR and hop-by-hop routing, usage of node sequence numbers from DSDV make the algorithm cope up with topology and routing information. Obtaining the routes purely on-demand makes AODV a very useful and desired algorithm for MANETs.

It’s harmful effects have been discussed and documented in studies, statements and reports scientists of different backgrounds, geographical and disciplines. Yet statesmen whose primary duties they are to initiate and implement programmes to curb, at least, if not completely eliminate the harmful effects tend to be unconcerned, or at most playing lip service to the issue. Gas flaring in Nigeria with its harmful effects started in the 1950s when oil exploration began. Studies have shown that Nigeria is the world’s worst gas farer. It is estimated that about 2.5 billion cubic feet (about 70 percent) of the 3.5 billion cubic feet gas produced annually in Nigeria are wasted by flaring. Successive Nigerian governments have not made concerted efforts to stop gas flaring. How has gas flaring in Nigeria contributed to global warming/climate change? What would Nigerian government do to completely stop gas flaring and thus its attendant harmful effects? Addressing these questions is the major plunge of this paper.
