Estimation and inter-comparison of dust aerosols based on MODIS, MISR and AERONET retrievals over Asian desert regions.

This study presents detailed analysis of spatiotemporal variations and trend of dust optical properties i.e., Aerosol Optical Depth (AOD) and Angstrom component over Asian desert regions using thirteen years of data (i.

Effect of different techniques of composting on stability and maturity of municipal solid waste compost.

Three methods for composting, aerobic, anaerobic and mixed type were compared in three locally fabricated composters of 20 L each, for their effect in accelerating compost maturity and stability using municipal solid waste. The composting process was monitored through determining the changes in temperature, pH, ammonium-N (NH(+)4-N), nitrate-N (NO- 3-N), carbon/nitrogen (C/N) ratio, NH(+)4-N/NO(-)3-N, total carbon, nitrogen (TN), potassium (TK), phosphorous (TP), humification index (HI), degree ofpolymerization (DP), humification rate (HR), CO2, humic acid (HA), fulvic acid (FA), and cation exchange capacity (CEC). Temperature increased rapidly from the mesophilic to the thermophilic stage and gradually decreased near the maturation phase.
