13 p, 1.7 MB The formation of illite from nontronite by mesophilic and thermophilic bacterial reaction / Jaisi, Deb P. (University of Delaware. Department of Plant and Soil Sciences) ; Eberl, Dennis D. (United States Geological Survey) ; Dong, Hailiang (Miami University. Department of Geology) ; Kim, Jinwook (Yonsei University. Department of Earth System Sciences)
The formation of illite through the smectite-to-illite (S-I) reaction is considered to be one of the most important mineral reactions occurring during diagenesis. In biologically catalyzed systems, however, this transformation has been suggested to be rapid and to bypass the high temperature and long time requirements. [...]

15 p, 252.9 KB Partitioning of Fe(II) in reduced nontronite (NAu-2) to reactive sites : Reactivity in terms of Tc(VII) reduction / Jaisi, Deb P. (Yale University. Department of Geology and Geophysics) ; Dong, Hailiang (Miami University. Department of Geology) ; Morton, John P. (Miami University. Department of Geology)
Clay minerals impart important chemical properties to soils, in part, by virtue of changes in the redox state of Fe in their crystal structures. Therefore, measurement of Fe(III)/Fe(II) and partitioning of Fe(II) in different reactive sites in clay minerals (during biological and chemical Fe(III) reduction) is essential to understand their role and their relative reactivity in terms of reduction and immobilization of heavy metal contaminants such as technetium. [...]

16 p, 1.1 MB Bioavailability of Fe(III) in loess sediments : An important source of electron acceptors / Bishop, Michael E. (Miami University. Department of Geology) ; Jaisi, Deb P. (Yale University. Department of Geology and Geophysics) ; Dong, Hailiang (China University of Geosciences. Key Laboratory of Biogeology and Environmental Geology of Ministry of Education.) ; Kukkadapu, Ravi K. (Pacific Northwest National Laboratory) ; Ji, Junfeng (Nanjing University. Department of Earth Sciences)
Fe-reducing micro-organisms can change the oxidation state of structural Fe in clay minerals. The interactions with complex clays and clay minerals in natural materials remain poorly understood, however. [...]

12 p, 1.3 MB Nontronite particle aggregation induced by microbial Fe(III) reduction and exopolysaccharide production / Jaisi, Deb P. (Miami University. Department of Geology) ; Dong, Hailiang (Miami University. Department of Geology) ; Kim, Jinwook (Naval Research Laboratory) ; He, Ziqi (The Ohio State University. Department of Civil and Environmental Engineering and Geodetic Science) ; Morton, John P. (Miami University. Department of Geology)
Clay particle aggregation affects a number of environmental processes, such as contaminant sorption/desorption, particle movement/deposition, and sediment structure and stability, yet factors that control clay aggregation are not well understood. [...]

13 p, 432.9 KB Role of microbial Fe(III) reduction and solution chemistry in aggregation and settling of suspended particles in the Mississippi River Delta plain, Louisiana, USA / Jaisi, Deb P. (Yale University. Department of Geology and Geophysics) ; Ji, Shanshan (Miami University. Department of Geology) ; Dong, Hailiang (Miami University. Department of Geology) ; Blake, Ruth E. (Yale University. Department of Geology and Geophysics) ; Eberl, Dennis D. (United States Geological Survey) ; Kim, Jinwook (Yonsei University. Department of Earth System Sciences)
River-dominated delta areas are primary sites of active biogeochemical cycling, with productivity enhanced by terrestrial inputs of nutrients. Particle aggregation in these areas primarily controls the deposition of suspended particles, yet factors that control particle aggregation and resulting sedimentation in these environments are poorly understood. [...]

3 p, 7.6 MB A brief introduction of coaching / Gajic, Deb (The Polesworth School - A Specialist Language College)
This is an edited version of an article that first appeared in the ATP Newsletter in October 2006.
Is it just another management fad or a valuable tool for working with students and colleagues? Deb Gajic gives a psychologist's perspective on the interpersonal system that's coming soon to a training day in your institution.
