pH-sensitive multiparticulate drug delivery system - how it works: - a nano-suspension was made from with the drug‚ and then chitosan bead were made‚ which were degradable selectively in the colon Advantage – area specific absorption of drug. And prevent drug form degradation‚ for non-soluble drugs Disadvantage – not for water soluble drugs (have to make suspension)‚ not for sustained release‚ Modified Push-pull osmotic systems – - how it works - the system has two compartments‚ one is hydrogel

How a Pogo Stick Works The pogo stick is a mechanical device that utilizes the spring’s ability to store energy. In this paper I will explain how the toy uses the laws of physics to provide hours of fun. There are a lot of forces acting on you and the pogo stick as you bounce along. We’ll take an in depth look at all of these forces and what part they play in the overall functioning of pogo sticks. The physical aspects can be broken down into sections to get a better understanding of what is going
