    Notes: Collisional interruption of coherent excitation of SF6 in the lower discrete region of its laser absorbing mode (ν3) have been studied using the recently developed quantum Monte Carlo wave function (QMCWF) method. The usual pure pump mode description up to 3ν3 and complete mixing of all modes (QC) above it have been assumed. The rotational and anharmonic splitting of the vibrational states upto 3ν3 are taken into account but splitting due to tensor interaction terms are neglected. Excitation to QC is represented by irreversible leakage from the coherent ladder modeled by an imaginary term in the Hamiltonian of the coherently excited vibrational rotational levels. QMCWF study has been carried out at the laser frequency 942.8 cm−1 for which the local time average populations in the intermediate excited vibrational states are found to be negligible. Large leakage occurs only from narrow band of ground rotational states due to 3 photon resonances but their number increases with increasing intensity. Two different collisional energy transfer models, one obeying symmetry imposed restrictions and propensity rule, and the other free from such restrictions except the fact that collisions restore the thermal distribution, have been used. Results show different pressure effects at different temperature and for different intensities. However, the two different models used for collisional rotational transition probabilities give similar enhancement of leakage at high intensities. © 1994 American Institute of Physics.

    Notes: Ferroelectric BaTiO3 thin films were grown on Si(100) substrates at a temperature of 600 °C by in situ metalorganic chemical vapor deposition. X-ray diffraction and transmission electron microscopy results suggested that the 〈110〉 direction of the BaTiO3 preferred oriented films is parallel with the (100) direction of the Si substrates. Auger electron spectroscopy measurements showed that the compositions of the as-grown films were with a uniform distribution throughout the thickness of the films and with a sharp interface. These results indicate that the failure to obtain BaTiO3 epitaxial films was due to the formation of an interfacial amorphous layer prior to the creation of the films.

    Notes: Basement and sub-basement crustal configuration of parts of the west Bengal basin has been delineated from inverse and forward modelling of refraction and wide-angle reflection data obtained along two east-west profiles: (a) Beliator-Burdwan-Bangaon (profile-1) about 180 km long and (b) Gopali-Tamluk-Port Canning (profile-2) about 140 km long. The study has revealed the existence of four groups of prominent refractors (velocities 1.7–2.1 km s−1, 2.7–3.2 km s−1, 3.7–4.2 km s−1, and 4.6–5.3 km s−1) overlying the crystalline basement with a velocity of 5.8–6.2 km s−1. Rajmahal Traps (velocity 4.6–5.3 km s−1, averaging 4.8 km s−1) occur beneath the base of the Tertiary sediments in the middle parts of the profiles. The presence of sub-Trappean Gondwanas is also indicated from the wide-angle reflection modelling supported by deep well lithological information. In general, depth to the basement is found to increase from west to east, with a maximum depth of around 10 to 11 km at the extreme eastern parts of the profiles. A basement upwarp, with a sharp flexure west of Bishnupur on profile-2 in combination with the fault west of Shantipur on profile-1 possibly brings into focus the regionally extending NNE-SSW ‘Hinge zone’. A low velocity layer (LVL) of about 2 to 3 km thickness (velocity 5.6–5.8 km s−1) has been inferred in the upper crust in this area. In general the thickness of the upper (including the sedimentary column) and the middle (6.4–6.6 km s−1 velocity) parts of the crust is found to be larger (thickness varying between 22 and 27 km) than the lower crustal column (interval velocity 6.8–7.0 km s−1 with a thickness of 5 to 10 km). The Moho lies at varying depths of 36 to 26 km along profile-1, with a prominent domal feature of about 40 km width between Satgachia and west of Shantipur. In the middle part of profile-2 the Moho occurs at depths of 32 to 34 km, with a mild flexure east of Tamluk. Configuration of the Moho indicates that the crust is more akin to continental in nature in the western and middle parts of the basin, whereas significantly thinned continental crust is indicated in the eastern and southeastern parts.

    Notes: Inheritance of resistance to Yellow Mosaic Virus (YMV) was studied in crosses of mungbean, black-gram and their interspecific crosses with Vigna sub-lobata. Resistance to YMV was recessive in the three Vigna species. The segregation ratios in F2 and back crosses indicated that the resistance was digenic recessive in the crosses of mungbean and in interspecific crosses of mungbean with blackgram and Vigna subiobata but YMV resistance was monogenic recessive in blackgram crosses.

    Description / Table of Contents: Résumé On a utilisé des résidus de patates douces, on résidu agricole amylacé, comme substral pour la production d'oxytétracycline parStreptomyces rimosus TM-55 par fermentation en milieu solide. On a détecté foxytétracycline le 3ème jour. Celui-ci a arteint sa concentration maximum le 6ème jour et celle-ci est restée constante jusqu'au 20eme jour. Les conditions optimales pour la production d'oxytétracycline sont les staivanies: un pH initial compris entre 5.5 et 6.5, l'ajout de 20% (p/v) de farine d'arachide dégraissée, comme seule source d'azote, 1.0% (p/v) de CaCO3 et 2.0% (p/v) de MgSO4.7H2O, une température d'incubation de 26 à 35°C pendant 6 à 7 jours. On a aneint 12.1 mg d'oxytetracycline par g de substrat.
    Notes: Abstract Sweet potato residue, a starchy agricultural waste, was used as a substrate to produce oxytetracycline byStreptomyces rimosus TM-55 in a solid-state fermentation. Oxytetracycline was detected on the third day, reached its maximum value on the sixth day and remained constant to the twentieth day. Optimal conditions for oxytetracycline production were an initial pH of 5.5 to 6.5, supplemented with 20% (w/v) defatted roasted peanut meal, as the sole nitrogen source, 1.0% (w/v) CaCO3 and 2.0% (w/v) MgSO4·7H2O, being incubated at 26 to 35°C for 6 to 7 days. Oxytetracycline reached 12.1 mg/g substrate.

    Notes: Abstract During oxytetracycline production by Streptomyces rimosus TM-55 on sweet potato residue in a solid-state column reactor, the moisture content increased by between 2 and 5% (w/w) during incubation, from an initial content of 70 to 73%, and pH initially increased from 6.0 to 7.3, followed by a gradual decrease to 6.2. Appropriate aeration enhanced oxytetracycline production, while mixing only once daily decreased it. The temperatures in the centre and upper layers of each reactor were higher than elsewhere in static non-aerated cultures. The maximum CO2 concentration ranged from 2.9 to 3.2% (v/v) and the minimum O2 concentration was 11.0 to 17.2% (v/v) in static cultures. Under optimal conditions, each gram of dry substrate produced the equivalent potency of 12 mg oxytetracycline.
