The Indian Ocean Experiment (INDOEX) was an international, multiplatform field campaign to measure long-range transport of air pollution from South and Southeast Asia toward the during dry monsoon season in January March 1999. Surprisingly high levels were observed over entire northern Intertropical Convergence Zone at about 6°S. We show that agricultural burning especially biofuel use enhance carbon monoxide concentrations. Fossil fuel combustion biomass cause a aerosol loading. growing...
The Halomonas species isolated from the rhizosphere of true mangrove Avicennia marina Indian Sundarbans showed enhanced rice growth promotion under combined stress salt and arsenic in pot assay. Interestingly, abiotic conditions, sp. Exo1 was observed as an efficient producer exopolysaccharide. study revealed that triggered exopolysaccharide production, which turn, increased osmotic tolerance strain. Again, like salt, presence also caused production turn sequestered showing a positive...
Heavy metals are mostly discharged from several anthropogenic sources in the lower Gangetic delta. They a matter of great concern due to their non-conservative nature. Zn, Cu, and Pb, were analyzed estuarine water thallus body tissue Enteromorpha compressa 10 different stations delta complex through three seasons. The levels heavy varied as per order Zn > Cu Pb both aquatic phase biological sample, irrespective stations. maximum concentration was observed Kakdwip (Stn. IV) Nayachar Island...
The way urbanization unfolds over the next few decades in developing countries of Asia will have profound implications for sustainability. One more important opportunities is to guide along pathways that begin uncouple these gains well‐being from rising levels energy use. Increasing use transport, construction, climate control houses and offices, industrial processes often accompanied by increasing atmospheric emissions impact human health, ecosystem functions, system. Agriculture, forestry,...
The problem of recombination electrons and ions in the lower ionosphere is studied both experimentally theoretically. experimental study involving, among others, measurements on phase height, polarization, absorption at 150 kc/sec, allows formulation a tentative distribution ionospheric coefficient over range 60 to 110 km. On basis this model, theories are examined detail. The during sudden disturbances also studied.
