Spectroscopic investigations are performed for 5-Bromo-1H-indole-carboxaldehyde by using experimental (FT-IR, FT-Raman) and theoretical (DFT) calculations. Vibrational assignments of the fundamental modes were assigned on the basis of Potential energy distribution (PED) calculations. Electron Localization Function (ELF) and Local Orbital Localizer (LOL) studies were performed to visualize the electron delocalization in the molecule. Frontier molecular orbitals (FMOs) and related molecular properties were computed. The electron-hole distribution of the molecule was also computed using Multiwfn 3.3.9 software to predict the charge transfer within the molecule. The total and partial density of states (TDOS and PDOS) and also the overlap population density of states (OPDOS) spectra were simulated. UV-Vis spectrum of the compound was also recorded. The reactive sites of the compound were studied from the MEP and Fukui function analysis. The charge delocalization and stability of the title molecule were investigated using natural bond orbital (NBO) analysis. The lung cancer activity of the title compound against p53 tumor suppressor proteins was studied using molecular docking analysis. The in-vitro cytotoxic activity of the molecule against human pulmonary lung cancer cell lines (A549) was determined by MTT assay.

Given a configuration of pebbles on the vertices of a connected graph G, a pebbling move (or pebbling step) is defined as the removal of two pebbles from a vertex andplacing one pebble on an adjacent vertex. The t-pebbling number, ft(G) of a graph G is theleast number m such that, however m pebbles are placed on the vertices of G, we can movet pebbles to any vertex by a sequence of pebbling moves.

This study examines the significance of media specific surface, porosity, pore size, and surface texture on treatment performance of the laboratory scale anaerobic packet-bed system. RG 51/91

In this research, carbonisation and chemical activation with ZnCl2 were employed to prepare carbonaceous adsorbents from sewage sludge and the mixtures of sewage sludge with coconut husk and peanut shell. RG 37/96

Using waste heat from a steam turbine, a pilot study was conducted in the laboratory to investigate the feasibility of using vacuum desalination process for water supply. RP 3/86

This dissertation is designed to provide a brief & essentially practical guide to current topic in mathematical modeling for adsorption by activated carbon with particular references. The purpose of study to check the applicability of model for the adsorption process in wastewater treatment using activated carbon. Master of Science (Environmental Engineering)

Disposal of sewage sludge is an increasingly expensive and environmentally sensitive problem throughout the world. Preparation of carbonaceous adsorbents from sewage sludge offers an attractive re-use alternative to the traditional disposal routes. This approach is consistent with the concept of sustainable technology and waste minimisation that is receiving much attention at present throughout the world, particularly in industrialised and densely populated areas.
