    Notes: Abstract Analysis of the multi-channel seismic reflection, magnetic and bathymetric data collected along a transect, 1110 km long parallel to 13° N latitude across the Bay of Bengal was made. The transect is from the continental shelf off Madras to the continental slope off Andaman Island in water depths of 525 m to 3350 m and across the Western Basin (bounded by foot of the continental slope of Madras and 85° E Ridge), the 85° E Ridge, the Central Basin (between the 85° E Ridge and the Ninetyeast Ridge), the Ninetyeast Ridge and the Sunda Arc. The study revealed eight seismic sequences, H1 to H8 of parallel continuous to discontinuous reflectors. Considering especially depth to the horizons, nature of reflection and on comparison with the published seismic reflection results of Currayet al. (1982), the early Eocene (P) and Miocene (M) unconformities and the base of the Quaternary sediments (Q) are identified on the seismic section. Marked changes in velocities also occur at their boundaries. In the Western Basin the acoustic basement deepening landward is inferred as a crystalline basement overlain by about 6.7 km of sediment. In the Central Basin possibly thicker sediments than in the Western Basin are estimated. The sediments in the Sunda Arc area are relatively thick and appears to have no distinct horizons. But the entire sedimentary section appears to be consisting of folded and possibly faulted layers. The comparatively broader wavelength magnetic anomalies of the Central Basin also indicate deeper depth of their origin. Very prominent double humped feature of the 85° E Ridge and broad basement swell of the Ninetyeast Ridge are buried under about 2.8 km thick sediments except over the prominent basement high near 92° E longitude. The positive structural relief of the buried 85° E Ridge in the area is reflected in magnetic signature of about 450 nT amplitude. Flexural bulge of the 85° E Ridge and subsidence of the Ninetyeast Ridge about 24 cm my−1 rate since early Eocene period have been inferred from the seismic sequence analysis.

    The effects of market structure characteristics on competitive reaction intensity: A longitudinal analysis (1991)
    Springer

    Notes: Abstract This study explores the effects of market structure characteristics and exogenous market interventions on competitive reaction intensity over time. It is found that moderate growth rate and moderate concentration induce greater competitive reactions. The effect of the exogenous intervention in the industry studied appears to have a dampening impact on competitive responses. Our research inquiry addresses some issues raised on competition, in general, by Weitz (1985) and specifically on competitive responses by Robinson (1988) and Gatignon, Anderson, and Helsen (1989).

    Notes: Abstract Purpose: To analyze the indications, functional results, and rates of graft rejection and failure after bilateral penetrating keratoplasty (PK) in a major eye care hospital and research center in India. Methods: Retrospective review of the case records of 38 patients who underwent bilateral PK and had at least 6 months follow-up after cornealtransplantation in the second eye. Results: The mean age of the 38 patients (20 M, 18 F) was 35 ± 25 years (range, 0.5 to 79 years). Mean follow-up was 49 ± 23 months (range, 13.4 to 116.4 months) after surgery in the first eye and 31 ± 22 months (range, 6.6 to 103.6 months) after surgery in the second eye. The average time interval between surgery in the first and second eye was 18 ± 10 months (range, 0 to 38 months). The commonest indications for surgery were corneal dystrophies (50%),aphakic bullous keratopathy (21%), and keratoconus (11%). Postoperatively, secondary glaucoma occurred in 2 first and 3 second eyes. Best-corrected visual acuity at last follow-up was 〉 6/12 in 34% of first eyes and 50% of second eyes, and was 〉 6/60 in 26% and 18% of first and second eyes respectively. Allograft rejection occurred in 4 of the first eyes and 3 of the second eyes. The two-year graft survival rate in first eyes was 70% and in second eyes was 83%. Worse outcomes were noted in grafts performed for secondary endothelial failure. Earlier graft failure occurred in first eyes (54 ± 5 months) compared to second eyes (79 ± 10 months) (Logrank Test p = 0.2311).Conclusions: Bilateral penetrating keratoplasty has reasonable success in selected patients. Corneal transplantation in the second eye does not seem to increase the risk of graft rejection in either eye.

    Notes: A consistent three-level time-split group finite-element method, suitable for the computation of viscous compressible flows in irregular geometric domains, is described. Exploitation of the group12 formulation permits an accurate and economical algorithm to be developed in a generalized-co-ordinate (ζ,η) space. A variable sweep cycle is used to accelerate convergence to the steady state. The method is demonstrated by computing laminar and turbulent flow past a trailing edge. The method uses an algebraic eddy viscosity model to represent turbulence and produces results in close agreement with the experiments and computations of Viswanath et al8.
