101 Firmage, Edwin B.Reflections on Mormon history: Zion and the anti-legal traditionSIR HENRY MAINE, OUR FIRST GREAT MODERN legal historian of the English language and law, in describing the paradigmatic shift from early feudal European society to a world of secular, territorial nation-states and market economy, observed that we had moved "from status to contract." "Status" assume...Heaven; Christians; Revelations1998
102 Ogburn, Joyce L.Report and commentary on the Faxon Institute: the second annual colloquium on scholarly communication issuesThe development of electronic means of publishing has forever changed the face of authorship, publishing and library services. Contracts are on the rise, fair use is waning, and this shift in emphasis has profound implications. For effective and economical dissemination of scholarly information to s...Electronic publishing; Libraries; Scholarly publishers1998
103 Morse, Michael DavidResonant two-photon ionization spectroscopy of jet-cooled RuCA resonant two-photon ionization study of the jet-cooled RuC molecule has identified the ground state as a 1?+ state arising from the 10?211?25rr42?4 configuration. The 3?i state arising from the 10?211?25rr42?312?1 configuration lies very low in energy, with the 3?3 and 3?2 components lying only 76...1998
104 Ehleringer, James R.Responses of boreal conifers to climate fluctuations: indications from tree-ring widths and carbon isotope analysesSpatial distribution and species composition of the boreal forest are expected to change under predicted climate change scenarios.

105 Zick, Cathleen D.Review of the economics of family time useTime is a limited resource. Yet, it is also the one resource with which all individuals are equally endowed on any given day. Why then is there such wide variation in how each of us chooses to use that time? What factors guide our decisions about time spent working versus time spent with family and...1998
106 Kowaleski-Jones, LoriSex, contraception and childbearing among high-risk youth: do different factors influence males and females?During adolescence, many young people begin to experiment with new roles. One important area of exploration is sexual activity, which involves a certain amount of risk-taking.1998
107 Shirley, Peter S.; Parker, Steven G.Single sample soft shadowsA simple extension to ray tracing is presented that creates visually plausible "soft" shadows with little extra computation. Although these soft shadows are approximate, they are robust and have penumbra widths that behave in a believable way, including accurate placement of singularities where penu...Soft shadows; Ray tracing; Penumbra width; Image generation1998
108 Henderson, Thomas C.; Thompson, William B.Smart sensor snowWe propose to deploy and exploit and large number of inexpensive sensors to obtain information or trigger actions over a wide geographic area. Sensors may be of diverse physical natures: acoustic, IR, seismic, chemical, magnetic, thermal, etc. We describe here three major issues: (1) sensor distribu...Smart sensors1998
109 Veranth, John M.; Pershing, David W.; Sarofim, Adel F.Sources of unburned carbon in the fly ash produced from low-NOx pulverized coal combustionThe unburned carbon in the fly ash produced from low-NOx pulverized coal combustion is shown to consist of a mixture of soot and coal char. The soot was identified by the presence of chains or aggregates of 10-50-nm-diameter primary particles in electron microscope images of both laboratory sample...Unburned carbon; Char1998
110 Armentrout, Peter B.Statistical modeling of competitive threshold collision-induced dissociationCollision-induced dissociation of (R1OH)Li+(R2OH) with xenon is studied using guided ion beam mass spectrometry.

113 Miller, Joel StevenStructure and magnetic properties of MnII[N(CN)2]2(pyrazine). An antiferromagnet with an interpenetrating 3-D network structureMn[N(CN)2]2(pyz) (pyz = pyrazine) orders antiferromagnetically at low temperature and possesses intralayer u-NCNCN and interlayer u-pyz ligands that form a pseudo-ReO3 interpenetrating network structure.Dicyanamide; Polydentate; Temperature1998
114 Normann, Richard A.; Shah, Maulik R.Study of printed spiral coils for neuroprosthetic transcranial telemetry applicationsWe have explored the use of printed spiral coils (PSC's) for neuroprosthetic transcranial telemetry applications. We fabricated two-dimensional PSC's on a thin (25 microns) polyimide substrate using copper (35 microns) as a conducting material. All the coils had a fixed inner diameter of 1.0 cm.
