Relative Burial Depths of Nakhlites: an Update
Introduction: Nakhlites are augite-rich cumulate rocks with variable amounts of olivine and groundmass plus minor Fe, Ti oxides [e.g., 1]. Our previous studies revealed that nakhlites showed correlated petrography and mineralogy that could be explained by different locations (burial depths) in a common cooling cumulate pile [e.g., 2]. We so far analyzed six of the seven currently known nakhlite...
متن کاملUsing "Residual Depths" to Monitor Pool Depths Independently of Discharge
As vital components of habitat for stream fishes, pools are often monitored to follow the effects of enhancement projects and natural stream processes. Variations of water depth with discharge, however, can complicate monitoring changes in the depth and volume of pools. To subtract the effect of discharge on depth in pools, residual depths can be measured. Residual depth is the difference in de...
متن کاملEstimating Water Depths Using Artificial Neural Networks
The real-time Everglades Depth Estimation Network (EDEN) has been established in the Everglades of South Florida, USA, to support a variety of scientific and water-management purposes. The expansiveness of the Everglades, limited number of gauging stations, and extreme sensitivity of fauna to small changes in water depth have created a need for accurately predicting water depths at locations be...
متن کاملDiffraction and depths-of-field effects in electron beam imaging at SURF III
Imaging an electron beam with visible light is a common method of diagnostics applied to electron accelerators. It is a straightforward way to deduce the transverse electron distribution as well as its changes over time. The electrons stored in the Synchrotron Ultraviolet Radiation Facility (SURF) III at the National Institute of Standards and Technology (NIST) were studied over an extended per...
متن کاملHidden 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...
