Digital simulation of the neonate cardiovascular and pulmonary systems
… the model was designed to emulate the blood gas chemistry of the neonate and it's effect on respiratory stimulus, cardiac output and Ductus Arteriosus shunting. Pulmonary and cardiac system dynamics were not considered in the simulation. The model underwent a series of tests in which …

An improved digital computer model of the neonatal respiratory system
… in order to accurately simulate infant blood gas chemistry and its effect on respiratory and circulatory control. The model is divided into five physiologic compartments: heart, brain, lungs, tissues, and cerebrospinal fluid compartment. Respiration is a function hydrogen ion concentration in …

Characterizing the geochemical reactions in overburden waste pile : Synerude Mine Site, Fort McMurray, Alberta, Canada
… analytical modelling (assuming diffusive gas transport) of in situ pore-gas 0₂ concentrations. Ca loading from carbonate mineral dissolution (resulting in C0₂ production) was also calculated using the simple one-dimensional modelling of measured pore-gas C0₂ concentrations. Mass balance …

Quantitative Chemical Analysis Throughout the FC CVD Process as a Route to Reliable Fibre Production and Research
… Infra-Red spectrometer integrated into the gas line to monitor the precursor feedstocks in real time. This has revealed the erratic and inaccurate behaviour of precursor delivery, held as responsible for the reactor’s poor performance up to this point. Precursor delivery reliability has now …

Aerosol carbon nanotube production via scalable microplasma synthesis of catalyst nanoparticles
… catalyst aerosols. Controlling temperature, gas chemistry, and flow conditions at which the catalyst aerosol and carbon precursor streams mix is shown to be critical for enabling CNT nucleation, controlling CNT diameter, and limiting iron and amorphous carbon impurities. Synthesis of …

Diversity and Activity of Bacteria in Basal Ice Environments
… were combined with nutrient, major ion, and gas chemistry analyses to evaluate the microbial assemblages immured in both sediment-rich and sediment-poor basal ice environments. The primary material for this study was a 4 m profile of basal ice collected from Taylor Glacier (Antarctica) but …

Modeling The Evolution Of Vehicle Exhaust Plume Near Road And In Laboratory Dilution Systems Using The Ctag Model
… the Comprehensive Turbulent Aerosol Dynamics and Gas Chemistry (CTAG) model. CTAG is designed to simulate the transport and transformation of multiple air pollutants in various environments. For near-road applications, CTAG couples the major turbulent mixing processes with gas-phase chemistry and …

An unexpected journey: experimental insights into magma and volatile transport beneath Erebus volcano, Antarctica
… petrologic data and experiments with surface gas observations in order to interpret degassing histories and the role of volatiles in magma differentiation, redox evolution, and eruptive style. This research focus has been driven in part by an abundance of studies on various aspects of the …

U-series dating, geochemistry, and geomorphic studies of travertines and springs of the Springerville area, east-central Arizona, and tectonic implications.
… This interdisciplinary study combines water and gas chemistry data, travertine morphology and geochronology, analysis of geologic structures, basalt geochronology, and river incision studies to formulate an integrative model for both travertine formation and for landscape evolution of this …

Crust-mantle interactions and connections with the geodynamic system in the origin and circulation of fluids in the Comoros Archipelago - Indian Ocean
… the first leader of the Commission on the Chemistry of Volcanic Gases (CCVG), who referred to volcanic gas emissions as a “telegram from the Earth’s interior”. This research represents an attempt to read and interpret as much as possible from such complex messages with regard to an area of …

High Fidelity Chemistry And Radiation Modeling For Oxy-Combustion Scenarios
… in an oxy-combustion atmosphere, several refined gas-phase chemistry and radiative property models have been formulated for laminar to highly turbulent systems. This thesis examines the accuracies of several chemistry and radiative property models employed in computational fluid dynamic (CFD) …
