1 Ailion, David CharlesSelf-switching Q-damping circuit for reducing transmitter ringdown time in high power pulse NMRIn this paper we describe a circuit for reducing the transmitter ringdown time and thereby improving the recovery time in pulse NMR experiments. The circuit uses only solid state devices and requires no external switching. For transmitter voltages less than 0.5 V peak to peak the effective resista...Circuits; NMR experiments; Rf pulse1970
2 Fu, YingbinMechanism of reductive activation of potato tuber ADP-glucose pyrophosphorylase.The potato tuber (Solanum tuberosum L.) ADP-glucose pyrophosphorylase activity is activated by a incubation with ADP-glucose and dithiothreitol or by ATP, glucose- 1-phosphate, Ca2+, and dithiothreitol. The activation was accompanied by the appearance of new sulfhydryl groups as determined with 5, 5...Glucosephosphates; Enzyme Activation; Adenosine Triphosphate1998
3 Kraus, Peter L.John Steele Gordon, Thread across the ocean: the historic story of the transatlantic cableA Thread across the Ocean is a tale of historic and heroic proportions which the author fails to do justice to. The topic is the historic laying of the first telegraph cables across the Atlantic; however, though it is an enjoyable read, it is not a scholarly work. The depth of this work could have ...2003
4 Liu, FengPhysical origin of hydrogen-adsorption-induced metallization of the SiC surface: n-type doping via formation of hydrogen bridge bondWe perform first-principles calculations to explore the physical origin of hydrogen-induced semiconductor surface metallization observed in β-SiC(001)-3 x 2 surface. We show that the surface metallization arises from a novel mechanism of n-type doping of surface band via formation of hydrogen bri...Metallization; Hydrogen adsorption; SiC; n-type doping; Hydrogen bridge bond2005-10
5 Eddings, EricModified CPD Model for Coal Devolatilization at UCTT ConditionsTo study coal pyrolysis behavior at underground coal thermal treatment (UCTT) conditions, a modified CPD (M-CPD) model was developed and evaluated using two scales of experiments as well as two different coals, Utah Sufco and Illinois #6. Compared with the original CPD model, three major aspects wer...Coal; pyrolysis; modeling; underground heating2019
6 Lombardo, Nancy T.So many meetings so little time: using IP videoconferencing to revitalize statewide committeesInternet technologies continue to transform the library profession and redefine how we communicate with professional colleagues and peers. IP (Internet Protocol) videoconferencing provides increased opportunities for librarians to engage in virtual teamwork and e-collaborations.

7 Stang, Peter J.Studies in the cycloproparene series: cycloaddition reactions of diarylmethylidenecycloproparenesDiarylmethylidenecyclopropanaphthalenes 4b-d add diphenylisobenzofuran (DPIBF) and α-pyrone across the exocyclic double bond to give ring expanded products 11b-d and 13b-d that result from subsequent relief of ring strain in the non-isolable spirocyclic intermediates 10 and 12, respectively. The be...Cycloproparene series; Cycloaddition; Diarylmethylidenecycloproparenes; Ab initio calculations; Strained aromatics; Acetylenic-iodonium salts; Crystal structures; Cyclobutanes, Diels-Alder cycloaddition; norcaradienes2001
8 Gopalakrishnan, GaneshTransaction ordering verification of the PCI 2.1 protocol using trace inclusion refinementWe define an abstract model of PCI, called PCIA, and show that PCI is a refinement of PCIA based on tract inclusion. We then show that no traces of PCIA violate the Producer/Consumer property using the mur? explicit state ennumeration model checker. Given that PCIA does not violate the Producer/Cons...PCI; PCIA; tract inclusion2000

10 Khan, Faisal HabibQuantifying device degradation in live power converters using SSTDR assisted impedance MatrixA noninterfering measurement technique designed around spread spectrum time domain reflectometry (SSTDR) has been proposed in this paper to identify the level of aging associated with power semiconductor switches inside a live converter circuit. Power MOSFETs are one of the most age-sensitive compon...2014-01-01
11 Miller, Joel StevenPhotoelectron spectra of transition-metal carbonyl complexes: comparison with the spectra of adsorbed COThe uv and x-ray photoelectron spectra of carbon monoxide and transition-metal (TM) carbonyl complexes have been studied. The systematic changes in these spectra were recorded as the number of metal atoms in the complexes was increased and as the bonding configuration of the CO changed. The observat...TM carbonyl complexes; electron binding energies; metal atoms1978

13 Tiwari, AshutoshManifestation of two-channel nonlocal spin transport in the shapes of Hanle curvesThe dynamics of charge-density fluctuations in a system of two tunnel-coupled wires contains two diffusion modes with dispersion iω = Dq2 and iω = Dq2 + 2τt, where D is the diffusion coefficient and τt is the tunneling time between the wires. The dispersion of corresponding spin-density modes de...2014-01-01
14 Khan, Faisal HabibMaximum power point tracking of stirling generator and ocean wave energy conversion systems using a two-stage power converterWave energy has become one of the most promising renewable energy resources nowadays. By using a linear generator/alternator, the periodic piston motion of the wave energy conversion system (WEC) can be converted to AC voltage with variable RMS amplitude and frequency; this process is comparable to ...2013-01-01
15 Miller, Jan D.Dispersed oil impact on froth stability in flotationFoam stability in flotation has been studied for more than half of the last century, however, the mechanisms responsible for the defoaming action of many presently used reagents are not completely understood. This research presents oil flotation data, which may be used in the evaluation of aqueous ...Particles; Defoaming; Surfactants2001
