Molecular detection of Methylotrophs from an Indian landfill site and their potential for biofuel production
Solid Waste Management
Emission of CH4 from landfills is a major cause of concern as CH4 is twenty four times more potent than CO2, as a greenhouse gas. However, landfills also harbor a group of bacteria called methanotrophs, which can oxidize CH4. They can be used for in situ bioremediation to reduce methane emissions...

Observational Uncertainty in Hydrological Modelling using Data Depth
Hydrology and water resources
For any river basin management, one needs tools to predict runoff at different time and spatial resolutions. Hydrological models are tools which account for the storage, flow of water and water balance in a watershed, which include exchanges of water and energy within the earth, atmosphere and...
Photocatalytic abatement of o-xylene using adsorption enhanced ZnO/GAC catalyst in a continuous flow reactor: Catalytic potential, Fate of o-xylene and its by-products
Air Quality
Photocatalytic abatement of o-xylene was investigated by immobilized ZnO on granular activated carbon (ZnO/GAC) under UV irradiation. Immobilization of ZnO increased the breakthrough time and removal capacity by 51 and 57%, respectively, in optimal conditions. The catalytic potential of the ZnO/GAC...
