The Uncatalyzed addition of acetic acid to norbornadiene
(The American Chemical Society: The Journal of Organic Chemistry, 1966-09-12)The uncatalyzed addition of acetic acid to norbornadiene (I) to give mixtures of ezo-dehydronorbornyl acetate (II) and nortricyclyl acetate (III) was studied. Rates of addition and ratios of II/III (degree of homoallylic ... -

Unfolding of the period-two bifurcation in a fiber laser pumped with two modulation tones
(American Physical Society, 1997-12)The effect of a small second frequency component on a pump modulated neodymium fiber laser is investigated experimentally and theoretically. This term, whose frequency is exactly half the primary driver, incites an unfolding ... -
Unusual oxidative behavior of (.eta.5-C5R5)M(CO)2 (R = H, CH3; M = Rh, Co) complexes at mercury and platinum electrodes
(The American Chemical Society: Inorganic Chemistry, 1987-06-17)The electrochemical oxidative behavior of a series of cyclopentadienyl and pentamethylcyclopentadienyl carbonyl complexes of rhodium and cobalt is described. The voltammetric, polarographic, and coulometric data from the ... -
An upper limit to the masses of stars
(Nature Publishing Group: Nature, 2005-03-10)There is no accepted upper mass limit for stars. Such a basic quantity escapes both theory, because of incomplete understanding of star formation, and observation, because of incompleteness in surveying the Galaxy. The ... -
Use of high-temperature and high humidity to test the adhesion of sputtered copper to a polyimide surface-modified by an AC Nitrogen Glow-Discharge
(Brill (VSP): Journal of Adhesion Science and Technology, 1995)We have used an extreme environmental stress test to study the adhesion of a thin sputtered copper film (0.5 mu m) to flexible polyimide (PI) substrates between 25 and 125 mu m thick. The polyimide types include Kapton ... -
Use of poly(ester-sulfonic acid) film-coated electrodes as amperometric detectors in flow injection analysis
(Elsevier: Talanta, 1995-12)Within the past several years significant advances have been made towards the development and incorporation of chemically modified electrodes as selective detectors for high performance liquid chromatography and flow ... -
Use of shift reagents for nuclear magnetic resonance studies of the kinetics of ion transfer in cells and perfused hearts

Using neural networks for controlling chaos
(The International Society for Optical Engineering (SPIE), 1994-03)A feed-forward backpropagating neural network is trained to achieve and maintain control of the unstable periodic orbits embedded in a chaotic attractor. The controlling algorithms used for training the network are based ... -
Using simulation software to solve engineering economy problems
(Elsevier, 2003)Some information required for solving problems in engineering economy problems can be fairly well defined. Much required information is uncertain, such as the actual cash flows from revenues and costs, the salvage value ... -
Variation in the type I interferon gene cluster on 9p21 influences susceptibility to asthma and atopy
(Nature Publishing Group: Genes and Immunity, 2006-03-08)A genome-wide screen for asthma and atopy susceptibility alleles conducted in the Hutterites, a founder population of European descent, reported evidence of linkage with a short tandem repeat polymorphism (STRP) within the ... -
Viral oncoprotein binding to PRB, P107, P130, AND P300
(Elsevier: Virus Research, 1995-02)The purpose of this review is to bring attention to some additional work in the tumor virus/tumor suppressor field which may have been overshadowed by reports describing adenovirus, SV40, and HPV oncoprotein binding to pRB ... -
Visualization of the regression of the hyaloid vasculature and retinal vessel formation in the newborn rat using FITC/Dextran
(Association for Research in Vision and Ophthalmology: Investigative Ophthalmology and Visual Science, 2005)Purpose: The regression of the pupillary membrane and hyaloid vasculature of the eye was observed in the newborn rat from postpartum days 1–36 by injection of FITC–dextran. We also observed the development of the retinal ... -
A VNIR/SWIR atmospheric correction algorithm for hyperspectral imagery with adjacency effect
(Elsevier Science B.V., Amsterdam, 2001-12)Radiometrically calibrated hyperspectral imagery contains information relating to the material properties of a surface target and the atmospheric layers between the surface target and the sensor. All atmospheric layers ... -
Voltammetric behavior of poly(vinylferrocene)
(Wiley: Journal of Polymer Science: Polymer Chemistry Edition, 1976-10)A voltammetric analysis of the electron-transfer process in poly(vinylferrocene) (PVF) has been carried out; the results indicate that the electrochemical behavior of ferrocene and PVF are quite similar. The field effects ... -
