1 Sarofim, Adel F.; Pugmire, Ronald J.13C NMR analysis of soot produced from model compounds and a coalSoot samples, including the associated organics, produced from an Illinois No. 6 coal (five samples) and two model compounds, biphenyl (three samples) and pyrene (two samples), have been studied by 13C NMR methods. The coal soot data served as a guide to selection of the temperature range that would...13C NMR; Biphenyl; Aromatic cluster size2001
2 Smith, Grant D.; Borodin, Oleg; Bedrov, Dmitro13C NMR spin-lattice relaxation and conformational dynamics in a 1,4-polybutadiene meltWe have performed molecular dynamics (MD) simulations of a melt of 1,4-polybutadiene (PBD, 1622 Da) over the temperature range 400?273 K. 13C NMR spin?lattice relaxation times (T1) and nuclear Overhauser enhancement (NOE) values have been measured from 357 to 272 K for 12 different resonances.

3 Miller, Joel Steven[Et4N]2[TCNE]2 (TCNE = tetracyanoethylene) - an example of an exceptionally long 2.827 Ã CC bondInterest in organic compounds exhibiting unusually long CC bonds has been the subject of several recent studies.1-3 The longest sp3-sp3 C-C single bond reported to date is 1.73 A°,1,2 whereas several [TCNE]22- (TCNE = tetracyanoethylene) dimers have been recently reported to form cation-assisted, l...Synthesis; Crystal; Solution2001
4 Fogel, Alan DaleA relational perspective on the development of self and emotionBegin with two premises. First, psychological experience always implies a connection, a relationship: with another person, with cultural tools or language, or with the natural environment. Life is a network of relationships. Second, psychological experience is always dynamic and changing. The sim...2001

6 Myers, Chris J.A standard-cell self-timed multiplier for energy and area critical synchronous systemsThis paper describes the design of a standard-cell self-timed multiplier for use in energy and area critical synchronous systems. The area of this multiplier is bounded by N rather than N2 as seen in more traditional combinational parallel array designs, where N is the word size. Energy has a polyn...2001
7 Anderson, Richard BryanAcquisitions in a wired world: where are we going?This is a frightening time to be a thirty-something acquisitions librarian. Convention dictates that I follow up that statement by saying that this is also a very exciting time to be a thirty-something acquisitions librarian, but I'll tell you what: it's mainly just scary. I worry a lot about wha...Libraries; Acquisitions; Librarians; Future; Electronic libraries2001
8 Armentrout, Peter B.Activation of methane by size-elected iron cluster cations, Fen+ (n=2-15): cluster-CHx (x=0-3) bond energies and reaction mechanismsThe kinetic energy dependences of the reactions of Fen + (n=2 - 15) with CD4 are studied in a guided ion beam tandem mass spectrometer over the energy range of 0-10 eV. All reactions exhibit thresholds and two main products, FenD+ and FenCD2+, are formed.Metal clusters; Iron ions; Bond energies; Dehydrogenation; Endothermic reactions; Transition metal ions2001

10 Mathews, V. JohnAn adaptive channel estimator for CDMA systems in multipath fading channelsABSTRACT CDMA systems in multipath fading channels need to estimate channel parameters for coherent detection of the transmitted signals. In this paper we present a simple but effective channel estimation algorithm that can be incorporated into most types of multiuser receivers to obtain good dete...2001

13 Myers, Chris J.Analog decoding of product codesA design approach is presented for soft-decision decoding of block product codes ("block turbo codes") using analog computation with MOS devices. Application of analog decoding to large code sizes is also considered with the introduction of serial analog interfaces and pipeline schedules.2001

16 Sanchez, Thomas W.Are planners prepared to address social justice and distributional equity?Planners have stated their commitment and responsibility to assure fairness in community and regional planning activities. Evidencing this is an abundance of literature on the theoretical perspectives of social justice and planning ideals. But is this stated concern for social justice and equity re...2001

20 Mathews, V. JohnBlind identification of bilinear systemsAbstract This paper is concerned with the blind identification of bilinear systems excited by higher-order white noise. Unlike prior work that restricted the bilinear system model to simple forms and required the excitation to be Gaussian distributed, the results of this paper are applicable to a m...2001
21 McDaniel, SusanBorn at the right time?: gendered generations and webs of entitlement and responsibilityAnalyses of social change and challenge in sociologies for women often start with some attention to generation. Yet, generation per se has been an underconceptualized sociological construct as a structural dimension of stratification, particularly gender stratification, or as a lens through which...Generation; Gender; Women2001

25 Lighty, Joann; Sarofim, Adel F.Carbon dioxide effects on metal vaporization during coal combustionCoal combustion products may take one of two forms. Residual ash (> 1 micron) is formed by particle shrinkage and breaking during combustion. Some material will vaporize and later recondense. During recondensation, these molecules have a high affinity for submicron particles because of the large sur...Coal combustion products; Metal vaporization; Carbon dioxide; Residual ash2001
