    Nighttime enhancements in ionospheric electron content: seasonal and solar cycle variation (1995)
    Springer

    Notes: Abstract Various characteristics of anomalous nighttime enhancement in ionospheric electron content (IEC) at Lunping (14.08°N geomagnetic), a station near the crest of the equatorial anomaly, have been presented by considering the IEC data for the 21st solar cycle. Out of a total of 1053 enhancements, 354 occur in pre-midnight and 699 occur in post-midnight hours, which indicates an overall dominance of post-midnight events at Lunping. The occurrence is more frequent during summer, less during the equinox and least during winter months. All the characteristics of the enhancements have seasonal dependencies and they reach their maximum values during summer months. The occurrence of the pre-midnight events show positive and post-midnight events show negative correlation with solar activity. The results have been discussed and compared with those at low-latitude stations in India and Hawaii and at the mid-latitude station, Tokyo.

    A dynamically heterogeneous coupled dissipation scenario of glass transition (1999)

    Notes: A dynamically heterogeneous coupled dissipation scenario of the glass transition is presented. The model predicts a splitting from a high-temperature single (αβ)-relaxation to low-temperature α- and β-processes at a certain temperature, TS. The model also predicts a glass transition and some anomalies dependent on the thermal history during the glass transition. Some general features of glass formers emerge from the predictions of the model proposed. © 1999 American Institute of Physics.

    The phase transition and transport properties of Sr0.56C60O1.5 (1995)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 67 (1995), S. 3417-3419

    Notes: X-ray diffraction and dielectric measurement have been applied to investigate the phase transition and transport properties of Sr0.56C60O1.5 which is obtained by the reaction of SrCl2 with C60 anion aquatic solution. The new compound has a similar structure, but different transport properties as compared with metallic Sr-doped C60. X-ray diffraction shows that a first-order phase transition around 100 °C is related to the rearrangement of Sr2+ in the interstitial sites of the C60 lattice. The step change of ac conductivity near 100 °C is also attributed to the hopping of Sr2+ between interstitial sites. The ionic conductivity indicates the possibility of synthesizing superionic conductors based on C60 and its derivatives. © 1995 American Institute of Physics.

    On a generalized nonlinearK-ɛ model for turbulence that models relaxation effects (1996)

    Notes: Abstract In this paper, based on a similarity that exists between the constitutive relations for turbulent mean flow of a Newtonian fluid and that for the laminar flow of a non-Newtonian fluid, and making use of extended thermodynamics, we develop a generalized nonlinearK-ɛ model, whose approximate form includes the standardK-ɛ model and the nonlinearK-ɛ model of Speziale (1987) as special cases. Our nonlinearK-ɛ model, which is frame indifferent, can predict relaxation of the Reynolds stress, unlike most standardK-ɛ models. Also, our model is in keeping with that of Yakhotet al. (1992). Most interestingly, the linearized form of our model bears a striking resemblance to the model due to Yoshizawa and Nisizima (1993); however, it has been obtained from a totally different perspective.

    Notes: Abstract  In this paper, based on a similarity that exists between the constitutive relations for turbulent mean flow of a Newtonian fluid and that for the laminar flow of a non-Newtonian fluid, and making use of extended thermodynamics, we develop a generalized nonlinear K—ɛ model, whose approximate form includes the standard K—ɛ model and the nonlinear K—ɛ model of Speziale (1987) as special cases. Our nonlinear K—ɛ model, which is frame indifferent, can predict relaxation of the Reynolds stress, unlike most standard K—ɛ models. Also, our model is in keeping with that of Yakhot et al. (1992).

    Flow of a non-Newtonian fluid between intersecting planes of which one is moving (1993)

    Notes: Abstract We study the flow of an Oldroyd-B fluid between two intersecting plates, one of which is fixed and the other moving along its plane. This problem was first considered by Strauss (1975) for the Maxwell fluid using a similarity transformation. We find that even in the case of a Maxwell fluid, which can be obtained by setting a specific parameter, say σ, in the Oldroyd-B model to zero, our results disagree with those of Strauss (1975). We find that circulating cells are present, adjacent to the stationary plate while Strauss (1975) finds them adjacent to the moving plate. We also delineate the effect of the coefficient σ, which is a measure of the elasticity of the flow, on the flow pattern. We find that an increase in the elastic parameter reduces the cellular structure.

    Anelastic and dielectric relaxations in CuO in the temperature range 90–160 K (1994)

    Notes: Abstract Internal friction and dielectric loss measurements, x-ray diffraction analysis and tensile tests as a function of temperature were carried out in CuO. Data from the experiments show that no phase transition or phase-like transition occurs between 90 K and 160 K instead, in this temperature range both internal friction and dielectric loss measurements display a relaxation peak with an activation of 0.23±0.01 eV. It is concluded that the behaviour of the high Tc superconductors with Tc 〉 80 K is not related to CuO.
