KEPLERTRANSIT DEPTHS CONTAMINATED BY A PHANTOM STAR

Remediation of trichloroethylene-contaminated soils by star technology using vegetable oil smoldering.

Self-sustaining treatment for active remediation (STAR) is an innovative soil remediation approach based on smoldering combustion that has been demonstrated to effectively destroy complex hydrocarbon nonaqueous phase liquids (NAPLs) with minimal energy input. This is the first study to explore the smoldering remediation of sand contaminated by a volatile NAPL (trichloroethylene, TCE) and the fi...

Estimation of Face Depths by Conditional Densities

The expected value of missing data in a sample taken from a multivariate normal probability distribution is the mean of the conditional distribution of the missing dimensions given the known dimensions. We explain the derivation of this result, demonstrate its application to face image processing, then use it in a new method for recovering shape from image data. The context of our work is the u...

modelling of the petroleum hydrocarbons concentration variation in different depths of a contaminated soil during phytoremediation using fuzzy logic

1. introduction isfahan oil refinery (isfahan, iran) is responsible for the production of huge amounts of oil waste. as the released organic compounds are highly toxic, carcinogenic, and mutagenic, they can potentially contaminate the soil and groundwater resources of the adjacent area. this is particularly important in isfahan where arid/semi-arid climate has limited the access to adequate sur...

Evaluation of Reflection Optical Imaging Characteristics Using Fluorescence with Near Infrared Wavelength at Different Depths of Tissue Equivalent Phantom

Hidden Depths

The radiograph on this issue’s front cover demonstrates a normal image of the abdomen. It is a favourite of mine and one that I use routinely in teaching undergraduate medical students. Take a good look. You may notice a curvilinear gas density projected within the pelvis. See it? This is what a tampon looks like (figure 1). It’s a subtle finding, but once seen, the radiographic configuration i...
