The variability of conventional sensors used for ultrasonic inspections can be greatly reduced by permanently installing them, therefore eliminating uncertainties caused by positional variations and coupling fluids. Much smaller changes are measurabl

Exposure to corrosive substances in high temperature environments can cause damage accumulation in structural steels, particularly in the chemical and petrochemical industries. The interaction mechanisms are complex and varied; however initial damage

The distributed point source method is commonly used to predict the complex acoustic field emitted by ultrasonic transducers. In this paper, it is presented as an alternative to conventional approaches often used when solving rough surface scattering

In ultrasonic thickness monitoring using permanently installed sensors, random signal variations due to coupling changes and manual operation are largely reduced. However, effects on the signal due to roughness introduced by corrosion and erosion pro

[1] Measurements of the isotope ratios of snow nitrate and atmospheric gas-phase HNO3 (15N/14N and 18O/16O) from Summit, Greenland provide new observational constraints on postdepositional processing of snowpack nitrate. The δ15N of NO3− is simila

A strong, unambiguous negative trend is found in the nitrogen isotopic composition (delta15N) of nitrate over the industrial period, on the basis of a 100-meter ice core from Summit, Greenland. This record indicates that ice-core nitrate reflects cha

[1] We quantify controls on seasonal changes of the oxygen isotope anomaly of nitrate (Δ17O(NO3−), wherein Δ17O ≈ δ17O − (0.52 × δ18O)) in snow at Summit, Greenland, in an effort to enable quantitative reconstructions of paleoatmospheric o

[1] To explore the seasonality in δ 15 N and δ 18 O of nitrate in Greenland snow, we describe a simple box model of local photochemistry. Isotope ratios of HNO 3 are controlled by the nitrogen isotope fractionation between NO and NO 2 , the ratio o
