1751 Ailion, David Charles; Morris, Alan H.Determination of lung water content and distribution by nuclear magnetic resonance imagingNMR imaging techniques are applicable to the assessment of lung water content and distribution because the NMR signal is, under certain conditions, proportional to tissue proton density. NMR imaging is noninvasive, easily repeatable, free from ionizing radiation, and particularly suitable for the as...Water content1986
1752 Miller, Jan D.Determination of Madelung constants for infinite and semi-infinite lattices by direct summationLattice sums for the electrostatic interactions in ionic crystals, first evaluated by Madelung, are now known to high degrees of accuracy. The problem of conditional convergence has been solved either by manipulations of a mathematical model of the lattice, or by directly summing over neutral group...lattices; madelung constants1976
1753 Ring, Terry Arthur; Eddings, Eric G.; Sarofim, Adel F.Determination of soot refractive index as a function of height in an inverse diffusion flameWith the scope of combustion diagnostics increasing, it is becoming ever more important for some of the more basic physical properties of soot to be addressed. Soot refractive index values were obtained as a function of height in a benzene inverse diffusion flame (IDF). The IDF was chosen for ease i...Inverse diffusion flame2007
1754 Hannon, James C.Determination of step rate thresholds corresponding to physical activity intensity classifications in adultsBackground: Current recommendations call for adults to be physically active at moderate and/or vigorous intensities. Given the popularity of walking and running, the use of step rates may provide a practical and inexpensive means to evaluate ambulatory intensity. Thus, the purpose of this study wa...2011
1755 Liu, FengDetermination of the Ehrlich-Schwoebel barrier in epitaxial growth of thin filmsWe demonstrate an approach for determining the "effective" Ehrlich-Schwoebel (ES) step-edge barrier, an important kinetic constant to control the interlayer mass transport in epitaxial growth of thin films. The approach exploits the rate difference between the growth and/or decay of an adatom and a...Ehrlich-Schwoebel barrier; Epitaxial growth; Step-edge barrier; Adatoms2006-11
1756 Scarpulla, MichaelDetermination of the infrared complex magnetoconductivity tensor in itinerant ferromagnets from Faraday and Kerr measurementsWe present measurement and analysis techniques that allow the complete complex magnetoconductivity tensor to be determined from midinfrared (11-1.6 μm; 100-800 meV) measurements of the complex Faraday (θF) and Kerr (θK) angles. Since this approach involves measurement of the geometry (orientati...Magnetoconductivity tensor; Ferromagnets2007-06
1757 Rogachev, AndreyDetermination of the superconductor-insulator phase diagram for one-dimensional wiresWe establish the superconductor-insulator phase diagram for quasi-one-dimensional wires by measuring a large set of MoGe nanowires. This diagram is roughly consistent with the Chakravarty-Schmid-Bulgadaev phase boundary, namely, with the critical resistance being equal to RQ ¼ h=4e2. Deviations fr...One-dimensional wires; Superconductor-insulator phase diagram; MoGe; Chakravarty-Schmid-Bulgadaev; Phase boundary2008-11
1758 Liu, FengDetermining the adsorptive and catalytic properties of strained metal surfaces using adsorption-induced stressWe demonstrate a model for determining the adsorptive and catalytic properties of strained metal surfaces based on linear elastic theory, using first-principles calculations of CO adsorption on Au and K surfaces and CO dissociation on Ru surface. The model involves a single calculation of the adsorp...Strained metal surfaces; Adsorption-induced stress; Adsorptive properties; Catalytic properties2004
1759 Kestle, John R. W.Determining the best cerebrospinal fluid shunt valve design: the pediatric valve design trialMyriad cerebrospinal fluid shunt valve designs are available (17, IS). None has ever been shown to be superior to another, although claims by neurosurgeons and shunt manufacturers of the merits of particular designs are numerous. Such is the case with two recent shunt valve designs, the Orbis-Sigm...Pediatric valve design; Shunt valves1996
1760 Reichler, Thomas J.Determining the tropopause height from gridded dataA method is presented to determine tropopause height from gridded temperature data with coarse vertical resolution. The algorithm uses a thermal definition of the tropopause, which is based on the concept of a threshold lapse-rate. Interpolation is performed to identify the pressure at which this th...Meteorology and Atmospheric Dynamics: Stratosphere/troposphere interactions; Numerical modeling and data assimilation; Meteorology; Atmospheric Dynamics: General circulation2003
1761 Johnston, Susan S.Developing an initial communicative repertoire: applications and issues for persons with severe disabilitiesResearchers and practitioners are increasingly aware of the extent of communicative relationships very early in development. Advances in understanding how communication develops and how it can be taught have made earlier communication intervention a viable undertaking for infants and toddlers who ex...Intervention; Context; Communicative functions1993

1763 Fogel, Alan DaleDeveloping through relationships origins of communication, self, and cultureI began to consider the study of relationships as an intellectual vocation in 1970, the result of two years of college teaching that was part of my work as a United States Peace Corps volunteer in Bogota, Colombia. After another year I began my doctoral training in the Department of Education at th...1993
1764 Miller, Jan D.Development and application of centrifugal flotation systems in wastewater treatmentFlotation as a wastewater treatment technique is designed to remove all particles generally encountered as very fine emulsions, suspended solids, and colloids from wastewater. Historically, Dissolved Air Flotation (DAF) has been used to achieve this removal. More recently, other flotation techniques...Wastewater treatment; centrifugal flotation; liquid cyclone mixing; hybrid centrifugal dissolved-air flotation; ASH; BAF; GEM; FF2007
1765 Drews, Frank; Westenskow, Dwayne R.; Agutter, James A.; Strayer, David LeeDevelopment and evaluation of a anesthesia drug displayBACKGROUND: Usable real-time displays of intravenous anesthetic concentrations and effects could significantly enhance intraoperative clinical decision-making.
