After the mining of mineral resource, mineland resources utilization became increasingly complicated. Soil and planting information can be used as the indicators to evaluate mineland reclamation level. In order to obtain the soil and planting information in real time, a CDMA-based soil-quality monitoring system was developed to wirelessly monitor air/soil environment and plant image in remote o...

The automatic reclamation of storage for unreferenced objects is very important in object databases. Existing language system algorithms for automatic storage reclamation have been shown to be inappropriate. In this paper , we investigate methods to improve the performance of algorithms for automatic storage reclamation of object databases. These algorithms are based on a technique called parti...

, Abstract Results of the laboratory reclamation of four sodic soils by the high salt water dilution method are reported. The exchangeable sodium percentage (ESP) of all soils was decreased by leaching with solutions of decreasing sodium but constant calcium concentration. Although a final leaching with water of low electrolyte concentration (EC,, < 100 micromhos/cm) did not produce a rapid dec...

Water reuse is becoming an important tool in water resource management regions with recurrent droughts and shortages, such as the Mediterranean. However, there are still obstacles preventing multiple application of projects, social acceptability financial problems. In this context, use green infrastructure constructed wetlands combination conventional mechanical treatments could represent a ver...

A wastewater treatment and reclamation facility in north-east Spain was monitored over 1 year to determine the occurrence and concentrations of different microbial indicators (Escherichia coli, fecal enterococci, somatic bacteriophages and spores of sulfite-reducing clostridia). The removal of the indicators and its relationships through the wastewater treatment and reclamation trains were eval...

Increasing reuse of reclaimed water for unrestricted agricultural and landscape irrigation is raising considerable concern for human health protection due to the potential spread and contact with human parasites and pathogens. Parasites pose a significant public health concern and the removal of helminth eggs is becoming a crucial treatment step when providing safe reclaimed water. Although lab...

Improperly abandoned gas wells threaten human health and safety as well as pollute the air and water. In the next 20 years, tens of thousands of new gas wells will be drilled into the Marcellus, Utica, and Upper Devonian shale formations of Pennsylvania. Pennsylvania currently requires production companies to post a bond to ensure environmental reclamation of abandoned well sites, but the size ...
