Mobility is one of the important issues in Mobile Ad hoc Networks (MANET). By definition, MANET nodes are free to move around and this may cause difficulty routing. routing protocols must consider factor when making decision. Zone Routing Protocol (ZRP) a hybrid protocol, which utilizes proactive reactive advantages. ZRP proactively maintains information within zone, while reactively discoverin...

We investigated the formation of delta-aminolevulinic acid (ALA)-pyrrole and subsequent color development used in determining ALA in urine. Of three condensation reagents examined--acetylacetone, ethyl acetoacetate, and methyl acetoacetate--the last was the best. When the ALA-pyrrole is reacted with Ehrlich's reagent in ethyl acetate according to one procedure, the optimum concentration of perc...
