    NO monomer and (NO)x polymeric chain chemisorption on Pt{110}: Structure and energetics (1999)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The chemisorption of NO on Pt{110}-(1×1) and -(1×2) has been studied using density functional theory slab calculations with the generalized gradient corrections. On both surface phases the monomeric species is the most stable and the short-bridge sites are energetically the most favorable adsorption sites. Monomeric NO is adsorbed upright with its molecular axis normal, bonded to the surface through the N atom. On the (1×2) surface at high coverage a polymeric (NO)x chain structure is identified; this may well correspond to the structure experimentally observed at high coverage on the (1×2) surface formed after heating a multilayer to temperatures between 80 K and 200 K, characterized by an NO IR band at 1760 cm−1. © 1999 American Institute of Physics.

    Characterization and orientation of adsorbed NO dimers on Ag{111} at low temperatures (1995)
    College Park, Md. : American Institute of Physics (AIP)
    The Journal of Chemical Physics 102 (1995), S. 7277-7280

    Notes: Reflection-absorption infrared spectroscopy (RAIRS) and near-edge x-ray absorption fine structure (NEXAFS) have been used, with isotopic 14NO/15NO mixtures, to determine the structure and orientation of the monolayer species formed by NO adsorption on Ag{111} at 40 to 60 K. The adlayer is composed of NO dimers bonded with the N–N axis in the surface plane and with the molecular plane tilted away from the surface normal by about 30°. This structure provides a simple basis for understanding the facile reaction to adsorbed N2O and O which occurs on heating to 70 to 90 K. © 1995 American Institute of Physics.

    Development of High-Protein Low-Cost Nigerian Foods (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 48 (1983), S. 0

    ISSN: 1750-3841

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Nigerian foods, akara, chin-chin, and puff-puff, were supplemented with full-fat cottonseed, defatted cottonseed, peanut, sesame or soybean flours. The foods were evaluated using a nine-point Hedonic scale by African and non-African panels. Foods were evaluated for appearance, texture, absence of greasiness, palatability and overall acceptability. The African panel rated all food products for all characteristics significantly (P=0.001) higher than the non-African panel. Protein quality evaluations indicated that full-fat cottonseed, defatted cottonseed and defatted peanut flours could be used to increase the quantity and quality of protein in traditional Nigerian foods.

    Incorporation of tetracycline into impeded and unimpeded mandibular incisors of the mouse (1978)
    Springer
    Calcified tissue international 26 (1978), S. 29-31 
    Details
    ISSN: 1432-0827
    Keywords: Tetracycline ; Incisor growth ; Incisor unimpeded eruption
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Summary Twenty-four hours after a tetracycline injection, the unimpeded, and more rapidly erupting, mouse mandibular incisor contained 20% to 44% more tetracycline than the contralateral, uncut incisor. It was concluded that the increased tetracycline incorporation reflected a higher rate of mineralization associated with faster tooth formation in the unimpeded tooth. By measuring the amount of tetracycline which became incorporated at different times after an incisor was shortened, it was possible to investigate an early stage of the response of the incisor to cutting. A significant increase in the capacity of the tooth to incorporate tetracycline was detectable 4 h after shortening the tooth, and this was maximal after another 4 h.

    Fe XVIII EMISSION LINES IN SOLAR X-RAY SPECTRA (1997)
    Springer
    Solar physics 171 (1997), S. 93-102 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract We have calculated intensity ratios for emission lines of Fexviii in the 13–94 Å wavelength range at electron temperatures characteristic of the solar corona, T e = 2–10 x 106 K. Our model ion includes data for transitions among the 2s 22p 5 , 2s2p 6, 2s 22p 43l, and 2s2p 53l (l = s, p, and d) states. Test calculations which omit the 2s2p 53l levels show that cascades from these are important. We compare our results with observed ratios determined from four solar X-ray instruments, a rocket-borne spectrograph, and spectrometers on the P78–1, OV1–17 and Solar Maximum Mission (SMM) satellites. In addition, we have generated synthetic spectra which we compare directly with flare observations from SMM. Agreement between theory and observation is generally quite good, with differences that are mostly less than 30%, providing limited support for the accuracy of the atomic physics data used in our calculations. However, large discrepancies are found for ratios involving the 2s 22p 5 2P3/2- 2s2p 6 2S line at 93.84 Å, which currently remain unexplained. Our analysis indicates that the FeXVIII feature at 15.83 Å is the 2s 22p 5 2P3/2 - 2s 22p 4(3P)3s 4P3/2 transition, rather than 2s 22p 5 2P3/2 - 2s 22p 4(3P)3s 2P3/2, as suggested by some authors.

    Transport and containment of plasma, particles and energy within flares (1983)
    Springer
    Solar physics 86 (1983), S. 79-90 
    Details
    ISSN: 1573-093X
    Source: Springer Online Journal Archives 1860-2000
    Topics: Physics
    Notes: Abstract Results from the analysis of flares observed by the Solar Maximum Mission (SMM) and a recent rocket experiment are discussed. We find evidence for primary energy release in the corona through the interaction of magnetic structures, particle and plasma transport into more than a single magnetic structure at the time of a flare and a complex and changing magnetic topology during the course of a flare. The rocket data are examined for constraints on flare cooling, within the context of simple loop models. These results form a basis for comments on the limitations of simple loop models for flares.

    Description / Table of Contents: Sommaire Cet article décrit le contrôle d'un certain nombre de variables physiologiques interactives par un ordinateur on-line fonctionnant en temps réel. Il est démontré qu'un système contrôlé par ordinateur peut, en surveillant les valeurs de la pression artérielle, le pourcentage de CO2 en fin de cycle et le pourcentage de O2 respiré, maintenir la respiration et l'anesthésie d'un animal recevant de l'air dans des tolérances strictes. Sous le contrôle d'un ordinateur, il est possible de compenser les perturbations aléatoires des paramètres du système et l'on peut traiter automatiquement les changements affectant les niveaux désirés des variables.
    Abstract: Zusammenfassung Die Steuerung einer Anzhhl von in Wechselwirkung stehenden physiologischen Variablen durch einen on-line, in real-time arbeitenden Rechner wird vorgeführt. Es wird gezeigt, dass ein komputergesteuertes System durch die Überwachung des arteriellen Blutdruckes, der endzyklischen CO2 Konzentration und der inspirierten O2 Konzentration, die Respiration und d Anaesthesie eines beatmeten Tieres innerhalb enger Toleranzgrenzen erbalten kann. Es ist möglich, unter Rechnerkontrolle statistisch auftretende Störungen der Systemparameter anzukompensieren, und Abweichungen von den gewünschten Werten der Variablen können automatisch berücksichtigt werden.
    Notes: Abstract Control of a number of interactive physiological variables by an online computer, operating in real time, is demonstrated. It is shown that a computer-controlled system, by monitoring values of arterial blood pressure, end-tidal CO2 percentage and inspired O2 percentage, can maintain the respiration and anaesthesia of a ventialted animal within close tolerances. Under computer control, it is possible to compensate for random disturbances of the system parameters, and changes in the desired levels of the variables can be dealt with automatically.
