Modified forms of chitosan beads were prepared and used for chromium removal from the aqueous solution. The prepared chitosan beads viz., protonated chitosan beads (PCB), carboxylated chitosan beads (CCB) and grafted chitosan beads (GCB) possess enhanced chromium sorption capacities (SCs) of 3239, 3647 and 4057 mg/kg respectively than the raw chitosan beads(More)
Web services have received much interest to support business-to-business or enterprise application integration but how to combine these services optimally in a continually growing search space is always a challenge. When there are a large number of Web services available, it is not easy to find an execution path of Web services composition that can satisfy(More)
Polymeric composites made up of nano-hydroxyapatite (n-HAp) with chitin and chitosan have been prepared and studied for the removal of Cu(II) ions from the aqueous solution. The sorption capacity (SC) of n-HAp, n-HAp/chitin (n-HApC) composite and n-HAp/chitosan (n-HApCs) composite were found to be 4.7, 5.4 and 6.2 mg/g respectively with a minimum contact(More)
Chitin (C), a biopolymer which showed moderate sorption capacity (SC) towards Cu(II) and Fe(III) was suitably modified to enhance the SC. Three types of modifications viz., protonated chitin (PC), carboxylated chitin (CC) and grafted chitin (GC) were carried out to increase the SC. The modified forms of chitin showed enhanced SC for both Cu(II) and Fe(III)(More)
Software organizations every day meet new challenges in the workflow of different projects. Scheduling the software projects is important and challenging for software project managers. Efficient Project plans reduce the cost of software construction. Efficient resource allocation will obtain the desired result. Task scheduling and human resource allocation(More)
