1 Miller, Jan D.Equilibrium and kinetics of copper extraction from ammoniacal solutions by hydroxoximes with particular emphasis on transport phenomenaThe chemistry of copper extraction from ammoniacal solutions by hydroxyoxime extractants was studied. Equilibrium measurements were made by shakeout experiments with subsequent analyasis of the aqueous and/or organic phases. The kinetic experiments were carried out in a single drop reaction cell in ...Reactant; Concentration; Dispersed1981
2 Miller, Jan D.Effect of surface oxidation on interfacial water structure at the pyrite (100) surface as studied by MDSFlotation provides a number of alternatives for the processing of gold ores containing sulfide minerals. e.g. flotation of free gold and gold-bearing sulfides to produce a gold-rich concentrate for regrinding, oxidative pretreatment and cyanidation.2014-01-01
3 Sperry, John S.Anatomy of the palm Rhapis excelsa, IX. Xylem structure of the leaf insertionSTEMS OF PERENNIAL PLANTS, particularly trees, represent a considerable investment in biomass. Trees can survive even under the most adverse conditions, but only if the hydraulic integrity of the stem is preserved. A very important and vulnerable part of the stem is the xylem. As water is pulled int...Palm stems; Palm stem anatomy; Palm leaves; Leaf insertion; Vessel network; Vessel-length distribution; Primary vascular stem tissue; Hydraulic architechture; Water column1983
4 Balasubramonian, RajeevQuantifying the relationship between the power delivery network and architectural policies in a 3D-stacked memory deviceMany of the pins on a modern chip are used for power delivery. If fewer pins were used to supply the same current, the wires and pins used for power delivery would have to carry larger currents over longer distances. This results in an "IR-drop" problem, where some of the voltage is dropped across t...2013-01-01
5 Poulter, Charles DaleTetartohedral twinning in IDI-2 from Thermus thermophilus: crystallization under anaerobic conditionsType-2 isopentenyl diphosphate isomerase (IDI-2) is a key flavoprotein involved in the biosynthesis of isoprenoids. Since fully reduced flavin mononucleotide (FMNH2) is needed for activity, it was decided to crystallize the enzyme under anaerobic conditions in order to understand how this reduced co...2014-01-01
6 Miller, Jan D.Anisotropic character of talc surfaces as revealed by streaming potential measurements, atomic force microscopy, molecular dynamics simulations and contact angle measurementsA study of the interfacial properties of the basal plane and the edge surfaces of talc is described in this paper. The isoelectric points measured at two different crystallographic surfaces by the streaming potential method were found to be similar and exist at about pH 3.0.

7 Miller, Jan D.Flotation chemistry of nonsulfide mineralsThe dimensions of nonsulfide flotation technology extend in many different directions, as might be expected from the diversity of t he mineral classes, which include soluble salt minerals (potash, borax, and trona), semi-soluble salt minerals (phosphate minerals, fluorite, calcite, and barite), ins...Nonsulfide minerals; Hydrophobic surface state; Oleate adsorption2002
8 Pugmire, Ronald J.Soot formation during coal pyrolysisSoot can be found in almost all combustion and pyrolysis systems. In a coal system, the impact of soot on coal combustion can be identified in two ways. First, soot particles suspended in the combustion flame significantly enhance radiative heat transfer near the burner due to their large surface ar...2001
9 Miller, Jan D.Bubble attachment time and FTIR analysis of water structure in the flotation of sylvite, bischofite and carnalliteWater structure is a most important parameter that influences the flotation of soluble salts. In this paper bubble attachment time measurements and FTIR analyses were performed to investigate the effect of water structure on the flotation behavior of sylvite (KCl), bischofite (MgCl2•6H2O) and carn...2010-01-01

The fact that the Government formulated or supplied the drawings, specifications, or other data does not license the ...2006
11 Miller, Jan D.Particle size segregation on a belt conveyorParticle size segregation is a common phenomenon in many particulate processes and has many undesirable effects. The size segregation which occurs on a belt conveyor causes a serious problem for on-line particle size measurement using image-based techniques. Whether particle size distributions mea...Particles; Size; Belt conveyors; Modelling1997

13 Khan, Faisal HabibMultilevel modular capacitor clamped DC-DC converterA novel topology of multilevel modular capacitor clamped dc-dc converter (MMCCC) will be presented in this paper. In contrast to the conventional flying capacitor multilevel dc-dc converter (FCMDC), this new topology is completely modular and requires a simpler gate drive circuit. Moreover, the new ...Capacitor-clamped converter; DC-DC converter; MMCCC; Multilevel modular capacitor2006-12
14 Vardeny, Zeev Valentine; Ehrenfreund, Eitan A.Illumination-induced metastable polaron-supporting state in poly(p-phenylene vinylene) filmsWe found an illumination-induced metastable polaron-supporting state in films of a soluble derivative of poly-p-phenylene vinylene (MEH-PPV). Pristine, nonilluminated MEH-PPV polymer films do not show longlived photogenerated polarons. Prolonged UV illumination, however, is found to induce a revers...Metastable polaron-supporting state; Poly(p-phenylene vinylene); PPV; MEH-PPV; Excitons2007-07
15 Korinek, KimThe effect of household and community on school attrition: an analysis of Thai youthWe analyze school attrition among youth in Kanchanaburi province, Thailand. We find that family investments in schooling are shaped by both household and local community contexts. There is an enrollment advantage for girls across different households and communities. We find that youth whose mothers...2012-01-01

19 Johnson, Bob L.Logic of school restructuring: a conceptual analysisPerusal of the educational literature since 1983 reveals the flood of attention given to reform in this decade. Fueled by reports much like A Nation at Risk and the efforts of personalities such as former Secretary of Education William Bennett, the rhetoric of reform abounds.
