Developments in nuclear microprobe analysis : the measurement of the spatial distribution of stable isotope tracersPollard, Patricia M. January 1981 (has links)
The potential of the nuclear microprobe for the determination of spatial distributions of stable isotope tracers has been examined. In a preliminary study the sensitivity of the isotope selective modes of operation of the microprobe (backscattering and nuclear reaction analysis) for the measurement of stable isotopes was examined using Mg, Si, Ni and Co as examples. The use of backscattering analysis coupled with high resolution detectors and heavy ion beams was assessed using Mg, Si, Ni and Ag as examples and found to be of limited application for stable isotope tracer studies.

Numerical study of the factors affecting the cycling of iron, sulfur and phosphorus in lake sedimentsTsandev, Iana January 2005 (has links)
In recent years, reaction transport models have gained importance in the study of diagenesis, which describes the chemical, biological and physical processes that take place in sediments. This project reports on factors influencing chemical profiles in lake sediments through an exploration of a generic reaction transport model which includes representations of the major reactions involved in the cycling of iron, sulfur and phosphorus. We have performed a global sensitivity analysis examining the steady state effects of physical, kinetic and thermodynamic factors on the magnitude, shape and burial concentrations of chemical profiles of iron, sulfur and phosphorus-bearing species. The environmental conditions were varied within a broad range typical of lake sediments. The exploration demonstrates the importance of the nature of boundary conditions (i.e. characteristics of the water column) and their coupling to the water column dynamics. The study additionally points to some chemical mechanisms such as precipitation of vivianite and scavenging of vivianite by sulfide having a dominant influence on the depth profiles of chemical species. Investigation also shows the importance of physical transport processes such as bioturbation near the sediment water interface and sedimentation velocity. Additionally, the distribution of reaction rates with depth and their role in shaping the profiles of chemical concentrations under typical environmental conditions were investigated.
