51 Symko, Orest GeorgeMagnetic shielding and relaxation characteristics of superconducting YBa2Cu3O7 tubesHigh-7c superconducting tubes have been developed for magnetic shielding of SQUIDs at 77 K. The characteristics of such tubes show that adequate shielding exists for magnetic fields up to a critical field determined by the current density of the tube. Relaxation phenomena with two different time de...YBa2Cu3O7 tubes; High-Tc; SQUID1989
52 Jarrard, Richard D.The magnetostratigraphy of ocean drilling program leg 105 sedimentsDuring Leg 105 of the Ocean Drilling Program, a series of 11 holes was drilled at three sites along a north-south transect in Baffin Bay and the Labrador Sea. Intermittent recovery and drilling disturbance, resulting in part from the harsh weather conditions encountered, hampered magnetostratigraph...1989
53 Couldwell, William T.Management of cysticercosis cerebriInfestation of the central nervous system (CNS) with the parasitic larval form of the cestode Taenia solium, Cysticercosis Cerebri represents an endemic problem in much of the underdeveloped world. In such areas, up to 4% of the population maybe affected by neurocysticercosis, and it accounts for u...Taenia solium; Cysticercosis Cerebri; Parenchymal cyst; Basilar cisternal cyst; Intraventricular cyst1989

55 Mathews, V. JohnMultiplication-free vector quantization using the L l distortion measure and its variantsVector quantization is a very powerful technique for data compression and consequently, it has attracted a lot of attention lately. One major drawback associated with this approach is its extreme computational complexity. This paper first considers vector quantization that uses the L1 distortion mea...1989
56 McDaniel, SusanNew stork rising? Women's roles and reproductive changesAnyone who has not been living in a remote cave will know that reproduction in the past decade has been changing rather dramatically. These changes have occurred on several fronts. Writing as a sociologist, I shall emphasize the social aspects of these changes, looking first at some of the changes ...In vitro; Birth rate; Artificial insemination1989
57 Miller, Joel Steven; Epstein, Arthur J.Optical properties of quinolinium tetracyanoquinodimethanide, [Qn(TCNQ)2] and (N-methylphenazinium)x(phenazine)1-x (tetracyanoquinodimethane) [(NMP)x(Phen)1-x(TCNQ)]We present here optical-absorption data of quinolinium ditetracyanoquinodimethanide [Qn(TCNQ)2] and (N-methylphenazinium)x(phenazine)1-x(tetracyanoquinodimethanide) [(NMP)x(Phen)1-x(TCNQ)] for 0.5 <_x<_ 0.6. These materials span the range of electronic structure from commensurate, to commensurate ...Commensurate; Lattice; Electron1989
58 Brinkman, Paul T.Options for cost analysisMany kinds of cost analysis are possible. Indeed, given the variety of purposes, methods, and types of cost, the number of permutations is virtually unlimited. In broad terms, one can disaggregate the universe of cost studies by distinguishing whether their primary purpose is to determine costs or t...Budget; Allocation1989
59 Armentrout, Peter B.Oxidation reactions at variably sized transition metal centers: Fen+ and Nbn+ + O2 (N=1-3)Cross sections for the reactions of Fen+ and Nbn+ (n = 1-3) with 02 are measured as a function of kinetic energy over a range of 0 to > 10 eV. In all systems, analysis yields insight into the kinetics and thermochemistry of the oxidation processes. Nbn+ reaction with 02 exothermically near the Lange...Metal clusters; Nobium ions; Iron ions; Exothermic reactions1989

61 Seeley, DonnPassword cracking: a game of witsA password cracking algorithm seems like a slow and bulky item to put in a worm, but the worm makes this work by being persistent and efficient. The worm is aided by some unfortunate statistics about typical password choices.Password cracking algorithm; Computer worms1989
62 Carter, Tony M.Path-programmable logicPath-Programmable Logic (PPL) is a structured IC design methodology under development at the University of Utah. PPL employs a sea-of-wires approach to design. In PPL, design is done entirely using cells for both functionality and interconnect. PPL cells may have modifiers that change either their ...Path-Programmable Logic; PPL1989
63 Couldwell, William T.Pituitary gland metastasis from adenocarcinoma of the prostateA case of prostatic carcinoma metastasis to the pituitary gland is reported. The presentation and rarity of such a lesion is addressed. The literature review yielded only isolated case reports of symptomatic brain metastases unassociated with bone disease from adenocarcinoma of the prostate. The man...Prostate; Pituitary gland; Adenocarcinoma; Metastasis; Transsphenoidal surgery1989

66 Miller, Jan D.Quantitative in-situ analysis of collector adsorption reactions by FTIR internal reflection spectroscopyResearchers in flotation chemistry have long sought to describe collector adsorption phenomena in greater detail including kinetics, orientation and interactions between adsorbed species. Now a quantitative description can be made in-situ using FTIR internal reflection spectroscopy. Details of the a...Fourier transform infrared spectrometers1989
67 Armentrout, Peter B.Reactions of Ar+, Ne+, and He+ with SiF4 from thermal energy to 50 eV c.m.Guided ion-beam techniques are used to measure the cross sections for reaction of SiF4 with Ar+, Ne+, and He+ from thermal to 50 eV. Charge transfer followed by loss of F atoms are the sole processes observed. All SiFx + (x = 0-4) products are observed, except for SiF4 + from reaction with Ne+ and ...Ion-molecule reactions; Tetrafluorosilane; Rare gas ions; Endothermic reactions; Plasma systems1989
68 McDaniel, SusanReconceptualizing the nuptiality/fertility relationship in Canada in a new ageFirst comes love; then comes marriage; along comes Joanie with a baby carriage. This straightforward temporal sequence so long taken for granted in North America may no longer be valid. With marriage rates declining, birth rates at an historic low, births occurring outside legal marriage, and dramat...Marriage; Family; Feminist1989
69 Coley, Phyllis D.Red coloration of tropical young leaves: a possible antifungal defense?Many woody species in humid tropical forests synchronously flush entire canopies of young red leaves. Numerous unsuccessful attempts have been made to explain the adaptive value of this visually striking phenomenon. In the humid tropics, fungal attack is a potentially important source of mortality f...Herbivory; Anthocyanin; Antifungal defense; Atta columbica; Panama; Leaf-cutting ants; Tropics; Young leaves1989
70 Christensen, Douglas A.Resonant inductive applicator for neck hyperthermiaWe have designed and phantom tested an inductive applicator especially suited for producing hyperthermia in cancerous regions in the neck. The applicator is tuned to resonate near 27 MHz; its inductive nature has the advantage of efficient coupling to the irregular neck anatomy. An inhomogeneou...Hyperthermia applicator; Phantom tests1989
71 Morse, Michael DavidResonant two-photon ionization spectroscopy of jet-cooled NiPtResonant two-photon ionization spectroscopy of jet-cooled NiPt has been used to investigate the possibility of <f-electron contributions to the bonding in this species. Based on an abrupt onset of predissociation, the bond strength of NiPt is assigned as D0 (NiPt) = 2.798 ? 0.003 eV. Comparisons of ...1989
