▪ Abstract Nuclear magnetic resonance (NMR) measurements of flowing materials are reviewed with emphasis on applications to multiphase flows. After a brief presentation NMR physics, experimental considerations related flow discussed. Both imaging and non-imaging as well topics such Earth's field rapid covered. Specific that follow tagging time-of-flight, phase measurement velocity, diffusion, turbulence, calibration validations. Finally, recent in the areas sedimentation, suspension flows...

To examine the ability of skeletal muscle congestive heart failure (CHF) patients to adapt chronic exercise, five performed localized nondominant wrist flexor training for 28 d. Inorganic phosphate (Pi) and phosphocreatine (PCr) were monitored by magnetic resonance spectroscopy in both forearms at rest during submaximal flexion exercise 6, 12, 24, 36 J.min-1 before after training. Simultaneous measurements limb blood flow made plethysmography J.min-1. Forearm mass endurance measured imaging...

In the rape or "Seiyo-Undai"1) (B.Napella) field, there are found in places a certain type of highly sterile individuals .Such individ uals can be easily detected among normal end flower season owing to their continuous and successive blooming.In 1927 authors collected some seeds from those individuals, offspring-tests were made for two generations which, contrary expectation, no plants appeared.Thus problem has lost its interest authors' attention not been paid years this type.In spring...
Abstract Rat lungs were imaged by 19 F projection MRI of hexafluoroethane, mixed with 20% oxygen to form the inhaled gas. The 3D image had 700 μm resolution, and data took 4.3 h acquire. Free induction decays collected in presence steady magnetic field gradients 686 different directions. To take advantage fast relaxation ( T 1 = 5.9 ± 0.2 ms), repetition time was 5 ms. eliminate signal loss from inhomogeneities, within 2 ms spin excitation (from 80 μs after 42‐μs π/2 pulses). singular value...

Abstract Profiles of flow velocity and dissolved oxygen concentration were studied by NMR microelectrodes near mixed population biofilms growing on polycarbonate substratum. The profile within the diffusion boundary layer profiles hydrodynamic can be described exponential equations.
We partially obstructed the left bronchi of rats and imaged an inert insoluble gas, SF 6 , in lungs with NMR using a technique that clearly differentiates normal ventilation. When inhaled fraction O 2 is high, concentrates dramatically regions lung low ventilation-to-perfusion ratios (V˙a/Q˙); therefore, these are brighter image than whereV˙a/Q˙ values or high. A second image, made when low, serves as reference because nearly uniform, regardless ofV˙a/Q˙. The quotient first images displays...
Application of microelectrode techniques, Nuclear Magnetic Resonance Imaging, and Confocal Laser Microscopy permitted analysis hydrodynamics, kinetics, internal structure in biofilm systems. The commonly accepted concept one dimensional diffusion through a three compartment model (bulk solution, biofilm, substratum) requires revision based on recent progress understanding the structures biofilms. Biofilms seem to form porous with network interstitial voids filled water, forming channels...
Nuclear magnetic resonance imaging (NMRI) was used to study fluid flow in a model bioreactor as function of biofilm formation. NMRI which the phase nuclear spins depends on spin velocity obtain distribution, whereas images predominately density were obtained by spin-lattice relaxation time weighted data. Velocity showed manner changed around biomass growth. We conclude that is an excellent tool these systems.
Abstract MR images of laboratory rat lungs that resolve the thin membranes separate lung lobes are presented. It appears capabilities in vivo small‐animal pulmonary MRI may rival those X‐ray CT. Free induction decay (FID)‐projection imaging was employed with particular attention to choice acquisition time. For a given nominal resolution, one obtains optimal point discrimination when time T acq normalized by signal constant is approximately 0.8–0.9, although better signal‐to‐noise ratio (SNR)...
