Microfluidic artificial lungs (μALs) are being researched for future clinical use due to the potential increased gas exchange efficiency, small blood contacting surface area, priming volume, and biomimetic flow paths. However, a current roadblock is need stack hundreds thousands of these small-scale μALs in parallel reach clinically relevant flows. The so many layers not only increases complexity projected cost manufacture μAL, but also could result devices which cumbersome, and, therefore,...
Prototype thermal neutron imaging arrays have been fabricated from semi-insulating (SI) bulk GaAs. The are 1 mm square Schottky diodes arranged in a 5/spl times/5 matrix. GaAs barrier radiation detectors relatively hard and can withstand higher gamma ray exposure fields than MOS-based Si diode arrays. devices use /sup 10/B to convert incident neutrons energetic Li ions alpha particles. truncated field effect observed with SI produces high low regions the device. Electron-hole pairs produced...
ABSTRACT A new technique is introduced to visualize flow through consolidated porous media. neutron based computer tomography system used inspect a series of laboratory core flood displacements. Two-dimensional advancement miscible and immiscible fronts were monitored in real time using radial Berea sandstone cores. The effect the heterogeneity core, viscous fingering water flooding cores have been observed are discussed. These experiments reveal that radiography has great potential study...
The avalanche mode of operation for junction transistors is encountered at higher-than-normal collector voltages. In this region the electrical character transistor profoundly altered because a voltage sensitive current-multiplication occurring junction. Current controlled <tex xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">N</tex> -type negative resistance characteristics suitable bistable are obtained. Important features these can be treated...
Microfluidic artificial lungs (μALs) are being investigated for their ability to closely mimic the size scale and cellular environment of natural lungs. Researchers have developed μALs with small capillary diameters (10–50 µm; increase gas exchange efficiency) large (~100 simplify design construction). However, no study has directly impact height on μAL properties. Here, we use Murray’s law Hagen-Poiseuille equation single-layer, small-scale heights between 10 100 µm. Each µAL contained two...
The remediation of soil contaminated with organic substances such as gasoline products is a subject growing concern. One method often employed flooding the water or water-surfactant mixture to wash contaminant down table. organics are then pumped out subsurface ground for treatment. This procedure has produced only limited results. It been speculated that this lack success due in part what known wetting front instability. Wetting instability can occur during infiltration liquid into porous...
To understand experiences of patients with genitourinary cancer who experienced delayed care due to the COVID-19 pandemic.
Selected types of low-frequency transistors were exposed to Co∞gamma radiation and a reactor flux neutrons. Forward reverse characteristic curves photographed as the irradiation progressed. Reverse currents emitter collector junctions recorded. These data are used distinguish changes surface recombination velocity from those associated with minority carrier lifetime. The character damage due gamma neutron is thus identified. Effects upon just environment compared successive exposure Co∞gammas
A GaAs-based neutron tomography system intended for the assay of nuclear fuel has been developed and tested. Its main components include a 16 pixel, dual in-line array /sup 10/B coated GaAs detectors, step motor driven table capable both linear rotational motion, custom data acquisition software automated collection. filtered-backprojection based reconstruction algorithm was implemented to reconstruct tomographic slices. Results from thermal epithermal imaging experiments are presented...
