Abstract: A method for processing a service request is provided, which includes: assigning, by a server, an identifier to a service request; if processing of a first service times out, marking a processing state as a first processing state, if the processing does not time out and the processing succeeds, continuously processing the second service, and if the processing times out, marking the processing state as a second processing state; and querying for the processing state of the service request according to the identifier regularly, acquiring a processing result of the service request, and sending the processing result to the user terminal, the processing result including a first processing result corresponding to the first service and a second processing result corresponding to the second service, where when it is queried that the second processing result is unsuccessful, an identifier is reassigned to the service request.

Abstract: A new and useful method and system for estimating LFG generation and gas permeability in a landfill or other subsurface-gas producing body of material is provided. The gas generation rate in a portion of a landfill or other subsurface-gas producing body of material is estimated by obtaining a time history record of atmospheric pressure that is representative of atmospheric pressure at a surface boundary of the portion of the landfill or the subsurface gas producing body of material, measuring the gas pressure at least at one selected location at the landfill (or subsurface body of material) site over a time period that is included in the time history record, and using the atmospheric pressure and the measured gas pressure over the time period to estimate LFG generation rate and gas permeability of the portion of the landfill or the subsurface gas producing body of material.
