The use of native soil bacteria to biodegrade explosives-contaminated soil under co-metabolic conditions has been demonstrated. The addition of food-grade surfactants could improve the process by enhancing the rates of explosives desorption from soil, thereby increasing the bioavailability of explosives for microbial degradation. The objective of this study was to decrease residence time in the...
Use of explosives, without desensitization could be lead to tragic explosions. Therefore a great interest to how decreasing of explosives sensitivities has been created. Because sensitivity decreasing to impact and friction can be cause to reduce dangers of their production, transmission and maintenance. Furthermore due to special applications, it tries to along with reduce sensitivities, speci...
The type of sensitizer used in commercial explosives is one of the important factors in determining the cost of production as well as the safety, performance, shelf-life and application characteristics of commercial explosives. In this paper, various sensitizing agents that are currently used, including aluminum powder, monomethyl ammonium nitrate, chemical gassing, microballoons and porous amm...
Identifying minor amounts of explosives with sensitivity, selectivity, accuracy and speed can be a great advantage for applications related to national security and environmental monitoring.Unfortunately, identification with high reliability of explosives is still a challenge and is largely unfulfilled. Today, fluorescence-based methods are widely used to detect explosives and products derived ...
The objective of this project is to compare growth and survival rate in Chinese carps reared under traditional culture conditions versus those reared in ponds treated with slurry (anaerobic fermented of cow manure). This experiment was conducted using two treatments one treatment using slurry and the other using cow manure plus chemical fertilizer as the control with three replicates for each....
the contamination of soil and water with petroleum hydrocarbons is a widespread environmental problem. the treatment requirement and removal of this pollutant are becoming more important in these days. total petroleum hydrocarbon (tph) has been reported to be toxic, carcinogenic, and an endocrine disrupter widely used in developing countries. various physical, chemical, and biological methods w...
this study experimentally investigates the effect of multi-walled carbon nanotubes (mwnt’s), as a reinforcing material, on the physical properties of heavy-weight oil well cements. a candidate well is selected and the properties of the cement slurry used in a problematic section of the well are tested in the laboratory. carbon nanotubes (cnt’s) are added as fibers to the cement slurry and the i...
