Elemental Stoichiometry of Freshwater Hyporheic Microorganisms
… on the bacterial diversity including elemental stoichiometry along a hyporheic flowpath underlying the Nyack floodplain. We isolated and characterized 44 bacterial strains, sampled microbial biofilm communities across the floodplain, characterized the bacterial isolates and determined elemental …

Growth-induced non-stoichiometry in complex oxide systems
… composition of the film, leading to cation stoichiometry deviations as large as 10% in SrTiO3, LaAlO3, and NdNiO3 systems. We demonstrate that such chemical deviations can lead to significant changes in the bulk thermal and dielectric properties of SrTiO3 and LaAlO3 films. We have also …

Consumer nutrient stoichiometry : patterns, homeostasis, and links with fitness.
… often influenced by human activities. Ecological stoichiometry provides one framework for understanding and predicting these linkages. Yet, as it has been extended underlying assumptions are often not evaluated. This dissertation shows that examination of implicit and explicit assumptions reveals …

Aneuploidy reveals insights into control of protein complex stoichiometry
… Here, we identify protein complex stoichiometry imbalances as a major cause of protein aggregation in aneuploid cells. Subunits of protein complexes encoded on excess chromosomes aggregate in aneuploid cells, which is suppressed when expression of other subunits is coordinately …

Stoichiometry and kinetic modeling of an anaerobic baffled reactor, The
… material to methane. An understanding of the stoichiometry and kinetics of an ABR receiving raw wastewater influent at ambient temperatures, is lacking. It is critical to develop this understanding in order to characterize the organic removal potential for further upscale and design of the ABR …

Kinetics and stoichiometry of the aquation reaction of pentaaquomonobromomethylchromium (III) perchlorate
… of this thesis was to determine the kinetics and stoichiometry for the aquation of the pentaaquomonobromonmethylchromium(III) complex. The complex was prepared by the reduction of dibromomethane by chromium(II). The products of aquation, in the absence of oxygen, were found to be …

The effect of resource stoichiometry on fish and macroinvertebrate nutrient excretion
Consumer-driven nutrient cycling has been shown to be an important process in supplying inorganic nutrients to autotrophic and heterotrophic organisms in aquatic ecosystems. Theory indicates that consumer nutrient excretion is influenced primarily by an organism's nutrient composition; however, an …

The effects of spatial confinement and oxygen stoichiometry on complex metal oxides
… Novel phenomena emerge by spatial confinement. Stoichiometry can have more profound effect on spatially confined materials than on the bulk. The purpose of the thesis is to explore and understand the spatial confinement and oxygen stoichiometry effect on complex metal oxides to pave the way for …

Stoichiometry of the interactions between endogenous Orai1 and STIM1 during store-operated Ca2+ entry
… Ca2+ in the ER. Elucidating the binding stoichiometry of STIM1 and Orai1 is essential for understanding Orai1 gating and mechanisms of SOCE. Most previous studies of SOCE used cells overexpressing STIM1 and/or Orai1, which might perturb their behaviours. This study used a HeLa cell line …

Adsorption of sulfate and phosphate at the mineral-water interface: isotherm, stoichiometry, and models
Processes occurring at mineral-water interfaces play critical roles for regulating the composition of surface and groundwater, for soil development, and for the availability of plant nutrients. Sulfate adsorption at three pH levels was conducted on y-AI203 and kaolinite. The adsorption isotherms …

Dietary Effects on the Stoichiometry of Growth, Regulation, and Wastes of Ozark Stream Insect Detritivores
… In this dissertation, I used ecological stoichiometry theory to examine effects of diet nutrient content and leaf litter type on growth, regulation, and wastes of aquatic invertebrate detritivores. I tested effects of leaf litter diet carbon:phosphorus (C:P) on growth and stoichiometric …

The stoichiometry and kinetics of biological heat generation in the aerobic stage of dual digestion
Over the past 10 years the Water Research Commission (WRC) has recognized the potential benefits of the dual digestion system for South Africa where anaerobic digestion is the preferred method of sludge stabilization. Accordingly, from 1981 to 1984 under WRC sponsorship, the Johannesburg City …
