Published 1992Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: We report a strong ac green electroluminescence (EL) in powder layers of terbium doped gadolinium oxysulfide (Gd2O2S:Tb) with methyl methacrylate as binder. An intensity of the order of 30 nits (Cd/m2) has been achieved. The EL emission spectra shows line emissions corresponding to 5D3 and 5D4 fluorescing levels of Tb3+ ions. A very sharply rising B-V curve normally related to insulator-phosphor interface properties of a thin film electroluminescent device has been observed in these cells. This indicates the possibilities of barrier formation due to the localized space charge region in the absence of any prominent interfaces leading to impact excitation of Tb3+ ions. This has further been confirmed by the excitation spectrum of Gd2O2S:Tb phosphor, which reveals Tb3+ impurity absorption bands related to 4f8 shell transitions.Type of Medium: Electronic ResourceURL: -

ISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: The ohmic mobility μ0 and the warm electron coefficient β of the electrons moving one-dimensionally in a quantum well wire (QWW) of In0.53Ga0.47As are investigated for lattice temperatures in the range of 4–10 K. Deformation potential acoustic, piezoelectric, ionized-impurity, and alloy scatterings are included considering the nonequipartition of phonons. β values are calculated by two models: one using a heated Fermi–Dirac distribution function, and the other using a more general moment method. Momentum relaxation is found to be controlled predominantly by alloy scattering. μ0 is larger for a QWW of greater cross section and decreases slowly with the increase of the lattice temperature. In both models used here, β is negative; its magnitude falls with increasing lattice temperature and is greater for larger cross sections of the QWW. However, ||β|| is larger in the heated Fermi–Dirac distribution function model.Type of Medium: Electronic ResourceURL: -

Published 1995Staff ViewISSN: 1089-7550Source: AIP Digital ArchiveTopics: PhysicsNotes: Small-signal ac mobility of two-dimensional (2D) degenerate hot electrons in a GaAs square quantum well is studied on a heated drifted Fermi–Dirac distribution function for the carriers. Carrier energy loss via longitudinal optic (LO) phonons, and the momenta losses via LO, acoustic and ionized impurity scatterings are considered. The ac mobility is found to drop off with frequency beyond 100 GHz although the drift velocity starts to lag behind the applied field at a lower frequency. The ac mobility μac and the phase angle φ increase with the rise of the channel width and the 2D carrier concentration. However, the 3-dB cut-off frequency f3 dB is found to decrease with increasing channel width. The values of μac and f3dB are higher but those of φ are lower at 300 K than that at 77 K. © 1995 American Institute of Physics.Type of Medium: Electronic ResourceURL: -

Published 1988Staff ViewISSN: 1089-7623Source: AIP Digital ArchiveTopics: PhysicsElectrical Engineering, Measurement and Control TechnologyNotes: We report here the design, fabrication, and testing of an integrated thermocouple gauge. The gauge uses a thin-film Cr heater and a thin-film Cu–Cr differential thermocouple on a 5-×3-mm glass substrate. The thermocouple measures the difference between the heater and the substrate temperature. Calibration of the thin-film Cu–Cr thermocouple gauge was done by using a standard K-type thermocouple as reference. At a constant difference temperature the measured power input to the heater is a function of the surrounding vapor pressure. The thermocouple gauge was calibrated using a McLeod gauge with He, Ar, N2, H2O, and CO2 gases. Our measurements show that the range of the gauge can possibly be extended to the μTorr range. This gauge uses a standard thin-film processing technique for fabrication resulting in a lower cost of production. Also, small size makes this gauge versatile and unique in comparison to many commercial gauges.Type of Medium: Electronic ResourceURL: -

ISSN: 1439-0523Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, NutritionNotes: The cytological status of plantlets regenerated from shoot apical meristems of Pisum sativum was investigated. Chromosome counts in root apices of in vitro regenerated plants showed a preponderance of diploid cells. Moreover, the karyotypes of root-tips from plants derived from culture and from normal plants were basically the same. Topics such as the treatment of chromosomal armlength data, simple statistical comparison of samples derived from normal and regenerated plants are discussed.Type of Medium: Electronic ResourceURL: -

Published 1990Staff ViewISSN: 1365-3040Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: BiologyNotes: Abstract. The objective of this study was to investigate the effects of water stress in sweet potato (Ipomoea batatas L. [Lam] ‘Georgia Jet’) on biomass production and plant-water relationships in an enriched CO2 atmosphere. Plants were grown in pots containing sandy loam soil (Typic Paleudult) at two concentrations of elevated CO2 and two water regimes in open-top field chambers. During the first 12 d of water stress, leaf xylem potentials were higher in plants grown in a CO2 concentration of 438 and 666 μmol mol−1 than in plants grown at 364 μmol mol−1. The 364 μmol mol−1 CO2 grown plants had to be rewatered 2 d earlier than the high CO2-grown plants in response to water stress. For plants grown under water stress, the yield of storage roots and root: shoot ratio were greater at high CO2 than at 364 μmol mol−1; the increase, however, was not linear with increasing CO2 concentrations. In well-watered plants, biomass production and storage root yield increased at elevated CO2, and these were greater as compared to water-stressed plants grown at the same CO2 concentration.Type of Medium: Electronic ResourceURL: -

ISSN: 1440-1681Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: 1. A series of 1 -benzylcycloalkylamines with cycloalkyl rings of five, six or seven carbons and with various benzyl ring substituents (3-C1, 4-C1, 4-F, 3-CF3) was prepared and tested for anorectic and motor activity effects in rats.2. Two potent, non-stimulant, anorectics were found: l-(3-chlorobenzyl)-cycloheptylamine, and its N-methyl analogue. The activity of these compounds resembled that of chlorphentermine.Type of Medium: Electronic ResourceURL: -

Published 1978Staff ViewISSN: 1440-1681Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: 1. A novel activity cage for rats is described. Eight light beams are aimed at a light-conducting perspex rod at the centre of a cylindrical cage. The photoresistor at the end of the rod detects the changes in light intensity produced by interruption of the light beams.2. The apparatus is simple to operate and was capable of detecting small differences in the motor activity of groups of rats.3. Dose-dependent increases in motor activity were produced by dexampheta-mine (1.36 to 27.3 μmol/kg, i.p.). The depressant effects produced by 20 μmol/kg doses of norfenfluramine were greater than those of fenfluramine. Large doses (100 μmol/kg) of tranylcypromine stimulated motor activity whereas its m-isomer, m-2-phenylcyclopropylamine, depressed motor activity.Type of Medium: Electronic ResourceURL:
