Groundwater discharge is an important component of global water cycle. Along with groundwater discharge, large amount of chemicals are transported and loaded into surface waters. This thesis investigates groundwater discharge in both terrestrial and marine environments using isotopic approaches. Radium quartet and radon-222 (222Rn), highly concentrated in groundwater and conservatively behaving during the transport, are proved to be effective tracers in quantifying groundwater discharge in various environments. Stable isotopes (δ 18O and δ 2H), significantly fractionated during evaporation, are useful and applicable in studying the water balance in arid waters. Groundwater discharge is an important component of global water cycle. Along with groundwater discharge, large amount of chemicals are transported and loaded into surface waters. This thesis investigates groundwater discharge in both terrestrial and marine environments using isotopic approaches. Radium quartet and radon-222 (222Rn), highly concentrated in groundwater and conservatively behaving during the transport, are proved to be effective tracers in quantifying groundwater discharge in various environments. Stable isotopes (δ 18O and δ 2H), significantly fractionated during evaporation, are useful and applicable in studying the water balance in arid waters. Desert lakes, lacking of surface runoff, are mostly supplied by groundwater discharge. These lakes play a vital role in maintaining desert water balance, creating unique landscapes, supporting distinctive ecosystems. In this thesis, radium quartet, 222Rn, δ 18O and δ 2H are used to estimate groundwater discharge into the Badain Jaran Desert (BJD) lakes and to reveal these lake evolutions. Most of the desert lakes are flow through lakes, reflecting groundwater discharge is larger than lake surface evaporation and explaining their existence in the extremely arid environment. The salinazation time of the desert lakes is estimated to start about 4000 yrs B.P. Radium and radon disequilibrium in the fractured aquifer system is used to estimate the hydrogeological parameters such as water residence time, effective surface area and mean aperture, based on long time monitoring of radium and radon activities in the spring water. Adsorption exerts a dominant effect in controlling radium quartet transport in fracture aquifer system.

The requirement to measure the real time, dynamic temperature of exhaust system gases is becoming more and more important in the areas of aeronautics, automotive (cars, trucks, etc), marine and industrial/environmental applications, in particular on a cycleby-cycle (CBC) basis. Monitoring exhaust gas temperatures of any power-plant can give important diagnostic information for the monitoring of fuel mixture, combustion efficiency etc. This 'diagnostic' information can be used to help 'dynamically' tune the combustion process or engine operation to assist in reducing exhaust emissions, optimize fuel flow rates and help improve overall efficiency of the system or engine. In order to realize this capability, it is necessary to monitor the dynamic temperature of the exhaust flows with a temporal resolution in the millisecond range. The fastest response time achievable by currently available temperature sensors which are robust enough to survive in these very hostile environments is of the order of several hundred milliseconds or greater. To this end, conventional measurement systems such as resistive-temperature sensitive devices, bi-metallic solutions or even optical solutions are orders of magnitude too slow to be of any use. In order to achieve the temporal resolution required, a new measurement methodology has to be developed. This work presents a novel temperature measurement sensor methodology, based on passive acoustic tone generators and specifically the labial flue pipe, that respond to the constrained pressure pulses generated by a pressure release mechanism in an exhaust or blow-down system. The work includes the development of a unique software suite that allows optimal tone generator design parameters be determined and identifies a unique interaction between the Ising efficiency number and the Reynolds number pertaining to the jet mechanism of the tone generator. Experimental results presented indicate a sensitivity to tone generator oscillation frequency, with pre-oscillation of the tone generators shown to further enhance this sensitivity.

▼ Mean arterial pressure (MAP) is regulated through changes in cardiac output (Q) and total peripheral resistance (TPR) where Q = heart rate (HR) x stroke volume (SV). Healthy heart rhythms have inherent variability and a decrease in heart rate variability (HRV) is associated with cardiovascular disease. Our preliminary data suggested there was variability in peripheral blood flow as well and it was predicted that aerobically trained women (TR) would demonstrate greater popliteal artery blood flow variability compared to untrained (UT). Additionally improvements in endothelial cell function (ECF) have been associated with exercise training and it was predicted that TR would show greater ECF through flow-mediated dilation (FMD) than UT and that FMD would be related to popliteal artery blood flow variability. Resting prone popliteal artery blood flow (ml/min) diameter (cm) and time averaged blood velocity (TAV; m/s) were measured at 1 min intervals for 10 min using Doppler Ultrasound in trained (TR N = 10) and untrained (UT N = 8) young females. Brachial artery systolic and diastolic blood pressures were measured simultaneously with blood flow mean arterial pressure (MAP) was estimated and popliteal artery conductance (1/popliteal artery resistance) was calculated from MAP and popliteal artery blood flow. Means and standard deviations (SD) were calculated from the 10 x 1 min measures and SD was used as a measure of variability. A 5 min occlusion of the calf was used to induce a hyperemic response in the popliteal artery and flow-mediated dilation (FMD) was measured using Doppler Ultrasound during and following the occlusion period. Student's t-test l mixed model 2x2 ANOVA and linear regression were used to analyze data. Mean resting popliteal artery blood flow was similar between groups (43.9 ml/min TR vs. 56.8 ml/min UT; p = 0.15). Popliteal artery blood flow variability was similar between TR and UT young women with a trend toward greater variability in UT (15.1 ml/min TR vs. 19.8 ml/min UT; p = 0.07). TR participants exhibited a larger arterial diameter at rest compared to UT (0.57 Â± 0.01cm TR vs. 0.51 Â± 0.01cm UT; p = 0.02). When FMD was corrected for resting diameter (%) there was no difference in maximum FMD between groups (10.9% TR vs. 6.7% UT; p = 0.27). Resting blood flow variability was found to be moderately correlated with resting popliteal artery conductance (r = 0.69; p < 0.01) but not resting MAP (r = -0.12; p = 0.64) or maximum FMD (r = 0.05; p = 0.86). Contrary to the hypothesis TR subjects did not demonstrate greater resting popliteal artery blood flow variability or greater FMD compared to UT. Resting popliteal artery blood flow variability was not related to maximum FMD but was moderately correlated to resting popliteal artery conductance. ; Kinesiology, blood flow, Exercise, popliteal Advisors/Committee Members: Timothy P.

▼ This thesis documents the efforts to characterize the Mach 4.5 flow over a flat plate model with a 30° compression ramp over a range of unit Reynolds numbers (Rel = 4‧105 – 1‧107 m-1) in low enthalpy (T0 = 293 K) and high enthalpy (T0 = 800 – 1250 K) flow conditions. The compression ramp model was designed, fabricated, and implemented in a hypersonic test facility (ACT-1) to simulate small-scale scramjet inlet operation. Flow visualization was provided by a schlieren imaging system and planar laser Rayleigh scattering (PLRS) to characterize the flow structure with various Rel. Three measurement methods were used to determine the frequency spectrum of flow perturbations: a high-frequency Shack-Hartmann wavefront sensor, a laser differential interferometer, and high-frequency pressure sensors. All three methods provide complementary results to indicate the existence of dominant frequencies of perturbations in the flow. It is determined that of these three measurement tools, Shack-Hartmann wavefront sensing is the most beneficial for this flow analysis. These measurements detect modification to the flow perturbation spectra during plasma actuation and across varied Rel. Damping of the perturbations in certain frequency bands occurred in the spectra of measurements taken in the corner separation bubble. In this way, the spectra indicate dominant frequency bands of perturbations occurring in regions of the boundary layer and separation bubble. It is shown, that in the highest tested Rel cases, initial disturbances in the freestream develop into strong perturbations, which significantly affect the boundary layer and separation zone size over the compression ramp. Both amplification and damping effects from the natural state are seen within different bands of the spectra of perturbations measured within the flow occurring over the separation region of the compression ramp collected during high-frequency plasma actuation (100 kHz). The amplification observed leads to a fast laminar to turbulent transition immediately after flow reattachment and potential stabilization of the shock wave structure. This effect was not observed at F = 50 kHz plasma pulsing frequency.

▼ The development of a novel combined 'ultrasonic/thermal' with 'ultrasonic multiple reflections' clamp-on meter for measuring a wide flowrate range of clean liquids in small diameter pipes is presented. Current existing flowmeters based on ultrasound cannot measure very low flowrates for single phase liquids. The ultrasonic/thermal technique can measure single phase flows in the range 0 to 0.6 m s⁻¹ in pipes with diameters as small as 15 mm. It can also detect and measure reverse flows. The minimum flowrate for the ultrasonic multiple reflection technique is about 0.55 m s⁻¹, and theoretically, the measurement accuracy increases with increased flow velocity. The ultrasonic/thermal technique is based on a heating element and transducer pair(s) which can be clamped to the outside of a pipe. With the heaters switched on, the changes in the temperature of the pipe and the liquid inside it result in changes in transit time. The flowrate can be therefore estimated by either the transit time difference across the pipe at the two symmetric locations with respect to the heater centre, or at one location with a heater off/on comparison. The latter approach was felt to be the promising for low flowrate measurements and therefore selected for the numerical and the experimental investigations. The multiple reflection technique was developed based on the conventional transit time flowmeter. This technique extended the measuring range of the flowmeter and provided cross calibration for the ultrasonic/thermal technique. A computer model was developed for the ultrasonic multiple reflection technique. However, there was insufficient experimental data to confirm the computer prediction. Results from computational fluid dynamics (CFD) analysis of the meter are presented. For vertical pipes an axisymmetric model was used, but the presence of buoyancy forces required the use of a 3-D model for horizontal pipes. Temperature and velocity distributions and ultrasonic transit times have been computed and are presented. In order to overcome the problem of mode conversion and refraction at the pipe wall/transducer mounting interface, novel transducers and mounting blocks are presented. A prototype heater and ultrasonic transducer system together with electronics for signal generation and transit time measurement have been designed and constructed. A hydraulic system has also been designed and constructed for testing the developed clamp-on flowmeter. Experimental results from this apparatus are presented and compared with the CFD predictions, and a technique for compensating for variations in inlet temperature is described. The full scale difference between the computed values and experimental results of the meter for low flowrate measurement was about 3.5%.

▼ The evaluation of measurement uncertainty is an essential part of measurement and data analysis. Measurement uncertainty is itself a measure of the “goodness” of the measured data and helps the analyst to make decisions based on the data. In the turbine engine testing world, accurate measurement of fuel flow is critical. Specific fuel consumption is a combination of thrust and fuel flow and is used to calculate the allowable payload and range of an aircraft as well as the cruising speed. Naturally, test customers (engine manufacturers, aircraft designers, and operators) are very sensitive to the accuracy of fuel flow measurement. This thesis presents a statistically defensible methodology for determining the uncertainty of fuel flow measurement in a turbine engine test cell. Fuel flow in most turbine engine test applications is measured using a volumetric turbine flowmeter. The mass flow rate of the fuel flow is calculated using the SAE ARP 4990 standard. The ARP 4990 method of fuel flow calculation is complicated and involves many parameters. An analysis of the influence coefficients for each of the input parameters was performed and found that four main parameters have a significant impact on fuel flow uncertainty: flowmeter frequency, flowmeter calibration, fuel operating temperature, and relative density at a chosen reference temperature. A method was developed for deriving a statistically defensible estimate of the uncertainty for each of the elemental error sources. The elemental uncertainties were then propagated to the result using both the Taylor’s Series method and the Monte Carlo method, which yielded nearly identical results. The method presented herein will aid in the evaluation of fuel flow uncertainty at AEDC. Compared to historical practices, this method results in a significant reduction in total fuel flow uncertainty and a much higher degree of statistical defensibility.

Non-invasive central aortic pressure measurements : calibration and clinical value – Chapter 5. Characterisation of age-related changes in aortic pressure and flow – Chapter 6. Relationship of cerebral arterial pressure and flow with aortic pressure and flow – Chapter 7. Published reviews, editorials and commentaries pertaining to the thesis topic – Chapter 8. Conclusion.

The elucidation of mechanisms whereby arterial stiffness with increasing age alters the propagation of pressure (and flow ejection) waves generated by each heart beat is still evolving and sometimes debated. The research described in this thesis aims to better characterise the age-related changes in ascending aortic blood pressure and blood flow non-invasively.

This thesis investigates four key areas:- (i) measurement of aortic stiffness with pulse wave velocity; (ii) non-invasive central arterial pressure measurements; (iii) characterisation of age-related changes in central aortic pressure and flow with non-invasive methodology; (iv) relationship of cerebral arterial pressure and flow with central aortic pressure and flow.

Findings of this investigation highlight the clinical importance of non-invasive measurement of central aortic pressure and aortic flow to determine ascending aortic impedance as a measure of cardiac load. The physical relationship between aortic pressure, flow and arterial impedance is quantified in terms of age-related changes. Changes in aortic flow pattern and means to derive aortic flow waveform from aortic pressure waveform non-invasively are compared with other methods. Results show that changes in the cardiac ejection pattern with age are better determined using magnetic resonance imaging compared to Doppler ultrasound techniques. Initial investigation of the effect of arterial stiffening, as occurs with age, shows that there is a relationship between the higher pressure pulsations from the heart and the damage in the brain due to the higher flow pulsations being transferred to the cerebral circulation.

This investigation confirmed the changes in central aortic blood pressure and flow ejection with aging. Derivation of the aortic flow pattern from central aortic pressure is feasible, through their relationship with aortic impedance. Increased pulsatility of arterial pressure and flow may cause damage to the microvasculature in the brain and may relate to the cognitive decline with aging and disease.

▼ Mean arterial pressure (MAP) is regulated through changes in cardiac output (Q) and total peripheral resistance (TPR), where Q = heart rate (HR) x stroke volume (SV). Healthy heart rhythms have inherent variability and a decrease in heart rate variability (HRV) is associated with cardiovascular disease. Our preliminary data suggested there was variability in peripheral blood flow as well and it was predicted that aerobically trained women (TR) would demonstrate greater popliteal artery blood flow variability compared to untrained (UT). Additionally, improvements in endothelial cell function (ECF) have been associated with exercise training and it was predicted that TR would show greater ECF through flow-mediated dilation (FMD) than UT and that FMD would be related to popliteal artery blood flow variability. Resting, prone popliteal artery blood flow (ml/min), diameter (cm) and time averaged blood velocity (TAV; m/s) were measured at 1 min intervals for 10 min using Doppler Ultrasound in trained (TR, N = 10) and untrained (UT, N = 8) young females. Brachial artery systolic and diastolic blood pressures were measured simultaneously with blood flow, mean arterial pressure (MAP) was estimated, and popliteal artery conductance (1/popliteal artery resistance) was calculated from MAP and popliteal artery blood flow. Means and standard deviations (SD) were calculated from the 10 x 1 min measures and SD was used as a measure of variability. A 5 min occlusion of the calf was used to induce a hyperemic response in the popliteal artery and flow-mediated dilation (FMD) was measured using Doppler Ultrasound during and following the occlusion period. Student's t-test, l mixed model 2x2 ANOVA, and linear regression were used to analyze data. Mean resting popliteal artery blood flow was similar between groups (43.9 ml/min TR vs. 56.8 ml/min UT; p = 0.15). Popliteal artery blood flow variability was similar between TR and UT young women, with a trend toward greater variability in UT (15.1 ml/min TR vs. 19.8 ml/min UT; p = 0.07). TR participants exhibited a larger arterial diameter at rest compared to UT (0.57 ± 0.01cm TR vs. 0.51 ± 0.01cm UT; p = 0.02). When FMD was corrected for resting diameter (%), there was no difference in maximum FMD between groups (10.9% TR vs. 6.7% UT; p = 0.27). Resting blood flow variability was found to be moderately correlated with resting popliteal artery conductance (r = 0.69; p < 0.01), but not resting MAP (r = -0.12; p = 0.64) or maximum FMD (r = 0.05; p = 0.86). Contrary to the hypothesis, TR subjects did not demonstrate greater resting popliteal artery blood flow variability or greater FMD compared to UT. Resting popliteal artery blood flow variability was not related to maximum FMD, but was moderately correlated to resting popliteal artery conductance.

▼ The development of a cost-effective multiphase flow meter to determine the individual phase flow rates of oil, water and gas was investigated through the exploitation of a single clamp-on gamma densitometer and signal processing techniques. A fast-sampling (250 Hz) gamma densitometer was installed at the top of the 10.5 m high, 108.2 mm internal diameter, stainless steel catenary riser in the Cranfield University multiphase flow test facility. Gamma radiation attenuation data was collected for two photon energy ranges of the caesium-137 radioisotope based densitometer for a range of air, water and oil flow mixtures, spanning the facility’s delivery range. Signal analysis of the gamma densitometer data revealed the presence of quasi-periodic waveforms in the time-varying multiphase flow densities and discriminatory correlations between statistical features of the gamma count data and key multiphase flow parameters. The development of a mechanistic approach to infer the multiphase flow rates from the gamma attenuation information was investigated. A model for the determination of the individual phase flow rates was proposed based on the gamma attenuation levels; while quasi-periodic waveforms identified in the multiphase fluid density were observed to exhibit a strong correlation with the gas and liquid superficial phase velocity parameters at fixed water cuts. Analysis of the use of pattern recognition techniques to correlate the gamma densitometer data with the individual phase superficial velocities and the water cut was undertaken. Two neural network models were developed for comparison: a single multilayer-perceptron and a multilayer hierarchical flow regime dependent model. The pattern recognition systems were trained to map the temporal fluctuations in the multiphase mixture density with the individual phase flow rates using statistical features extracted from the gamma count signals as their inputs. Initial results yielded individual phase flow rate predictions to within ±10% based on flow regime specific correlations.

▼ This doctoral thesis addresses the mixing of highly viscous Newtonian fluids (corn syrup solutions) in a novel aerated reactor equipped with a central impeller (a pitched blade turbine in upward or downward pumping mode) and a wall scraping anchor. The non-intrusive electrical resistance tomography (ERT), dynamic gas disengagement method (DGD), design of experiments (DOE), computational fluid dynamics (CFD), and population balance model (PBM) were employed to characterize the performance of this novel aerated system. The performance criteria to be examined were mixing time, power uptake, gas holdup, and bubble size distribution. In this study, novel correlations were developed to estimate the gassed power drawn by the coaxial mixer, mixing time, and gas holdup. In addition, to obtain a master power curve, two new dimensionless correlations were proposed for the generalized power number and gas flow number by incorporating the equivalent rotational speed for the coaxial mixer, speed ratio (central impeller speed/anchor speed), and the central impeller power fraction into these two correlations. The experimental data demonstrated that gas flow affected the aerated anchor power consumption and central impeller power consumption in different manners. It was also found that at the higher fluid viscosity and beyond the critical speed ratio of 10, the anchor power consumption was increased by increasing the speed ratio (i.e. decreasing the anchor speed). It was shown that in the presence of gas, the anchor impeller in combination with the upward pumping pitched blade turbine in the co-rotating mode exhibited shorter mixing times and lower power consumption than the anchor-downward pumping pitched blade coaxial mixer. To enhance the efficiency of the aerated mixer, it is critical to investigate the influence of the gas-liquid flow within the vessel on the bubble size distribution (BSD) and the local and global gas holdup. To achieve this goal, the effects of the bubble breakup and coalescence on the BSD within the vessel were incorporated into the CFD model through the CFD-PBM coupling. The experimental and simulation results showed that beyond the critical speed ratio of 10, the volume fractions of the large bubbles decreased while the volume fractions of the small bubbles increased.

▼ Three-dimensional non-invasive measurement capability is often a necessity to unravel the physical phenomenon in fluid mechanic problems such as flow field characterization in wall-bounded turbulent flows and microfluidic devices. Among all the 3D optical flow diagnostic techniques, digital inline holographic particle tracking velocimetry (DIH-PTV) provides the highest spatial resolution with low cost, simple and compact optical setups. Despite these advantages, DIH-PIV suffers from major limitations including poor longitudinal resolution, human intervention (i.e. requirement for manually determined tuning parameters during tracer field reconstruction and extraction), limited tracer concentration, small sampling volume and expensive computations. These limitations have prevented this technique from being widely implemented for high resolution 3D flow measurements. In this study, we present our novel high-fidelity DIH-PTV algorithm with the goal of overcoming all the above mentioned limitations. Specifically, the proposed particle extraction method consists of multiple steps including 3D reconstruction, 3D deconvolution, automatic signal-to-noise ratio enhancement and thresholding, particle segmentation and centroid cacluation, and inverse iterative particle extraction. In addition, the processing package is enriched with a multi-pass 3D tracking method and a cross-correlation based longitudinal displacement refinement scheme. The entire method is implemented using GPU-based algorithm to increase the computational speed significantly. Validated with synthetic particle holograms, the proposed method can achieve particle extraction rate above 95% with ghost particles less than 3% and maximum position error below a particle diameter for holograms with particle concentration above 3000 particles/mm3 within sampling volumes of ~1 mm longitudinal length. Such improvements will substantially enhance the implementation of DIH-PTV for 3D flow measurements and enable the potential commercialization of this technique. The applicability of the technique is validated using the experiment of laminar flow in a microchannel and the synthetic tracer flow fields generated using a DNS turbulent channel flow database. In addition, the proposed method is applied to smooth- and rough-wall turbulent channel flows under two different settings of high-resolution near-wall and whole-channel measurements (i.e. sampling volume is extended to the entire depth of the channel). In the first case, using a microscopic objective and local seeding mechanism, DIH-PTV resolves near-wall flow structures within a sampling volume of 1 × 1.5 × 1 mm3 (streamwise × wall-normal × spanwise) with velocity resolution of ~100 μm (vector spacing). In the second case, the measurement volume is extended to the whole-channel depth by seeding the entire channel. Under this setting, the 3D velocity fields are obtained within a sampling volume of 14.7 × 50.0 × 14.4 mm3 with a velocity resolution of ~ <1.3 mm per vector, comparable to other the-state-of-the-art 3D…

▼ This dissertation focuses on the development and application of optical techniques to visualize and characterize hypersonic wake flows in shock tunnels. Simulations of these flows are conducted and used to compare with the experimental results. The work presented covers three topics. Firstly, a time-resolved diode-laser based resonantly enhanced differential interferometry visualization is introduced. This new technique is capable of visualizing the transient behavior of wake flows under close-to-rarefied conditions, which is not possible with standard schlieren or interferometric methods. Secondly, measurements of velocity and temperature using planar laser-induced fluorescence (PLIF) around a generic planetary entry capsule model are presented. The model is mounted without potentially flow-disturbing mounting structures, creating a wake flow field similar to that of a space vehicle. The first two-component velocity map of such an entry-type hypersonic flow is presented, showing the velocity vector field in the inner wake, which has not previously been measured accurately. The theoretical understanding of the PLIF Doppler velocimetry technique is extended by describing the phenomenology behind the systematic error due to laser attenuation, one of the most important sources of bias error associated with this technique. With little additional effort, the rotational temperature in the same flow field is measured as well. The third topic focuses on the comparison between the measured velocities and temperatures with simulations using the direct simulation Monte Carlo method. Good agreement is found, except in the inner wake downstream of the model close to the centerline. These discrepancies are attributed to effects of localized transition from laminar to turbulent flow, causing higher temperatures and different velocity profiles in the far wake compared to the laminar simulations. The availability of non-intrusively measured global velocity and temperature data allows effect of transition on these parameters to be quantified with unprecedented resolution.

▼ Over the last 25 years, it has been established that the red blood cell (RBC) is a major determinant in blood flow, which it can modulate through release of adenosine triphosphate (ATP). Although RBCs store intracellular ATP in mM concentrations, measurements indicate that the cells release nM concentrations when stimulated by deformation, hypoxia (lowered oxygen tension), or incubation with pharmacological stimuli such as hydroxyurea (HU), which is the only approved drug for treatment of sickle cell disease. Upon release, RBC-derived ATP can induce vessel dilation via activation of endothelial cell nitric oxide synthase (eNOS) to produce nitric oxide (NO). To probe the fate of increased ATP release from human RBCs incubated with the drug hydroxyurea, a traditional soft polymer platform was utilized to facilitate measurement of cell-to-cell communication between RBCs and a cultured endothelium. This device contained an array of micron-scale channels through which RBC samples were pumped. The sample flow was separated from a detection well by a porous polycarbonate membrane. Stimulated ATP released from the RBCs diffused across the membrane to the detection wells and was measured using the luciferin-luciferase chemiluminescence assay, integrated with a plate reader for detection. RBCs incubated with 100 uM of HU released on average 2.06 ± 0.37 times more ATP relative to the control sample. Through the use of various inhibitors, this increase in ATP release was subsequently demonstrated to depend on RBC deformability, RBC NOS activity, and the cystic fibrosis transmembrane conductance regulator protein (CFTR). The fate of the measured RBC-derived ATP was also investigated by probing ATP signalling to an adjacent cultured endothelium.ATP release from RBCs increases in response to hypoxia, or lowered oxygen tension; however, the dependence of RBC ATP release on oxygen tension has not been investigated. To enable measurement of RBC ATP release and oxygen tension in a flowing stream of RBCs, a 3D printed device was designed to accomodate commercial transwell inserts for ATP measurements, as well as threaded Clark-type electrodes for amperometric oxygen measurements. The device consisted of a channel 2 mm wide and 0.5 mm in height with two ports for analyte detection and one threaded port for an electrode. The Clark-type electrode was fabricated from gold and silver wires secured into a finger tight fitting. Oxygen standards and RBC samples were prepared using air and argon purged buffers. Using the 3D printed device, RBC ATP release and oxygen tension were measured simultaneously from prepared RBC samples. Relative to controls, RBC ATP release increased significantly in response to systematically lowered oxygen tension with a maximum increase of 2.38 ± 0.43 fold more ATP when exposed to 5.35 ± 0.12 ppm oxygen. ATP release saturated, i.e., was not significantly different, at lower oxygen tensions. This increase in ATP release was inhibited by incubating RBCs with the cell stiffening agent, diamide. The dependence of hypoxic… Advisors/Committee Members: Spence, Dana M, Jones, Arthur Dan, McCracken, John, Chan, Christina.
