The remote sensing of stack gases by infrared emission spectroscopy has been studied analytically. An expression is derived relating the concentration of gaseous pollutants to the infrared band parameters and the mean temperature of the stack gases. The band parameters employed are independent of the resolution of spectrometers used in remote sensing or in… (More)
Conclusions The SOz readings obtained with the Thomas Autometer are substantially accurate even when significant levels of NO and NOz also are present. This specificity for SOe in the presence of nitrogen oxides is due to the nature of the absorbing reagent and absorption system used. Other gases such as HCI, Cln, and NH3, although not considered to be… (More)
The ir spectral emission of a variety of minerals and rocks was measured at a specimen temperature of 20 degrees C. A multiple-scan interference spectrometer was used. The samples were located within a cold-box during the measurements, the experimental arrangement thus simulating the conditions to be found in the field.
A new ground-based technique for estimating the density of nesting Adélie penguins (Pygoscelis adeliae) within occupied habitat is described and evaluated using an experimental approach with model penguins. In this set-up, an operator takes photos with a camera mounted on a 3-m pole at pre-determined sampling locations within habitat occupied by nesting… (More)
Quirks are particles that are charged both under the standard model and under a new confining group. The quirk setup assumes there are no light flavors of the new confining group, so that while the theory is in a confining phase, the quirk-antiquirk distance can be macroscopic. In this Letter, we reinterpret existing collider limits, those from monojet and… (More)
Two samples of snow petrel Pagodroma nivea mumiyo (solidified stomach oil) from Heimefrontfjella (74°34′36″S, 11°13′24″W) in Dronning Maud Land, Antarctica, were radiocarbon dated at 37,400 ± 1,500 and 3,120 ± 70 years old (dates are corrected for the ‘reservoir effect’). The age of the older sample provides further evidence that snow petrel colonies have… (More)
Infrared reflection spectra (2500-250 cm(-1)) of some minerals and rocks were recorded with a multiplescan interference spectrometer. Samples were small, irregular, and unpolished. Spectra were obtained with some samples approximately 1 mm in diameter. Emission of samples was obviated by using the interferometer as chopper.
