The non conventional adsorbents process remarkable adsorption capacity for the removal of heavy metals like Cd‚ Cr‚ Cu‚ Fe‚ Hg‚ Mn‚ Ni and Pb‚ surfactants‚ dyes‚ colour‚ organics from the industrial and municipal effluent. This paper represents the review of past work on removal of heavy metals by biosorption by using low cost adsorbents in natural and modified forms. Attempts are also made

Lab report NF-κB 1. Aim The aim with this lab was through using ELISA-based technique learn how IL-1 and LPS activate the NF-κB signaling pathway in insulin-producing cells and see if the activation can be prevented through inhibition of proteasomal activity. In addition the purpose of this lab was to detect whether NF-κB activation leads to induction of the iNOS enzyme or not. 2. Background NF-κB is a transcription factor that in its inactive form is bound to IκB‚ which is a cytoplasmic inhibitory
