    Integration of spin valves and GaAs diodes in magnetoresistive random access memory cells (1999)
    [S.l.] : American Institute of Physics (AIP)

    Notes: A magnetoresistive random access memory, based on a dynamic random access memory-like floor plan, is demonstrated for an array of magnetic memory cells. Each memory cell consists of a giant magnetoresistive spin-valve structure in series with a GaAs diode. Any single bit in the matrix can be addressed using a coincident current scheme, both for write and read operations. The integration of a series diode in the memory cell yields, for this first demonstrator, read signals of approximately 10 mV. © 1999 American Institute of Physics.

    Studies on ferric oxide hydroxides (1996)
    Springer
    Journal of materials science 31 (1996), S. 2199-2205

    ISSN: 1573-4803

    Notes: Abstract The effects of sulfate ions on the formation and physico-chemical properties of ferric oxide hydroxides were studied using various techniques. Samples prepared from 0.1 M Fe(NO3)3 solution without sulfate ions contain mixtures of goethite and hematite, whereas basic sulfates of varying composition were formed from solutions containing sulfate: iron (III) ratio greater than and equal to one. Goethite samples of very narrow particle size range, spherical shape, microporous nature, high surface area, high true density and low packing density and surface acidity, which are very necessary for good catalysts and ferrite making, were obtained at low sulfate: iron (III) ratios (0.25∶ 0.5).

    Description / Table of Contents: Zusammenfassung Es wird eine Differenzenlösung für die Strömung um eine plötzlich in Bewegung gesetzte, unendlich ausgedehnte senkrechte Platte hergeleitet, wobei folgende Annahmen zugrunde liegen: 1.*Anwesenheit von anderen Gasen in gewisser Konzentration (CO2, Wasserdampf, etc.) 2.*Konstanter Wärmefluß an der Platte Geschwindigkeits- und Temperaturprofile, Widerstandsbeiwerte und Nusselt-Zahlen sind graphisch dargestellt. Die Einflüsse der modifizierten Grashof-Zahl Gm, der Eckert-Zahl E und der Schmidt-Zahl Sc auf die Strömung werden diskutiert.
    Notes: Abstract A finite-difference solution to the flow past an impulsively started infinite vertical plate is derived by assuming 1) presence of species concentration like water vapour, CO2 etc. and 2) constant heat flux at the plate. The velocity and the temperature profiles, the skin-friction and the rate of heat transfer are shown graphically. The effects of the modified Grashof number, Gm, the Eckert number E, the Schmidt number Sc on the flow of air are discussed.

    Fe-MFI zeolite catalyzed C3 alkylation of benzene (1995)
    Springer
    Catalysis letters 32 (1995), S. 319-325 
    Details
    ISSN: 1572-879X
    Keywords: Fe-MFI ; ZSM-5 ; C3 alkylation ; cumene ; benzene

    Topics: Chemistry and Pharmacology
    Notes: Abstract Benzene alkylation with isopropanol has been carried out over ZSM-5 and Fe-MFI zeolites. It was observed that Fe-MFI zeolite showed a better selectivity for cumene (isopropylbenzene) andi/(i+n) propylbenzene ratio. This can be attributed to the acidity characteristic of the zeolite. The effects of variation in reaction conditions such as temperature, mole ratio of benzene/isopropanol and WHSV on the activity and selectivity of Fe-MFI are discussed.

    A Neo-Lurian Approach to Assessment and Remediation (1999)
    Springer
    Neuropsychology review 9 (1999), S. 107-116 
    Details
    ISSN: 1573-6660
    Keywords: Luria ; neuropsychology ; assessment ; neo-Lurian ; PASS ; remediation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Psychology
    Notes: Abstract The first part of this article presents an operational battery of tasks for measuring the four cognitive processes of Planning, Arousal–Attention, and Simultaneous and Successive processing (PASS) not only based on the qualitative data provided in Luria's syndrome analysis, but also taken from tasks in experimental cognitive psychology and neuropsychology. The second part of the article presents a remedial program based on PASS for enhancement of reading. Because this part provides in some detail the efficacy of the remedial procedure, it simultaneously validates the PASS constructs as well. In both parts of the article, I have been unmistakably guided by Luria's views: Tests are approaches to investigating cognitive functions, and the purpose of testing is to guide rehabilitation.
