    Notes: A method which combines thermal and plasma dissociation of a methane/hydrogen gas mixture for low-pressure chemical vapor deposition of diamond is described. A hot, thin-walled, refractory metal cathode is used to generate a high-current, low-voltage discharge. The substrates are located on the anode and immersed in the plasma emanating from the cathode tip. No auxiliary substrate heating is employed. Polycrystalline diamond particles and films are obtained on silicon (100) and molybdenum substrates at growth rates of 1–3 μm/h.

    Effects of filament and reactor wall materials in low-pressure chemical vapor deposition synthesis of diamond (1988)

    Notes: Well-faceted diamond crystals and polycrystalline films have been produced by low-pressure, hot-filament-activated, chemical vapor deposition with the use of methane/ hydrogen gas. The effects on growth and morphology of varying filament and reactor tube materials as well as tube diameter are reported. Tungsten and tantalum filaments, operated under similar conditions, produced diamonds at essentially the same growth rates (typically ∼2 μm/h) and with similar crystallographic properties. Platinum filaments produced only graphitic deposits. Diamond growth and morphology appeared not to be influenced by changing the reactor wall material from fused quartz to Al2O3 or Pyrex or by varying the tube diameter.

    Nonlinear optical processes in a polymer waveguide: Grating coupler measurements of electronic and thermal nonlinearities (1988)
    Woodbury, NY : American Institute of Physics (AIP)
    Applied Physics Letters 53 (1988), S. 2011-2013

    Notes: We report here the first clear demonstration of intensity-dependent phase shift due to electronic nonlinearity in a nonlinear polymer waveguide in which propagation distances over 5 cm have been achieved with total attenuation of ∼1.2 cm−1 . Intensity-dependent coupling angle, intensity-dependent coupling efficiency, and limiter action behavior have been observed in the polyamic acid waveguide using grating excitation with 400 fs, 80 ps, and 10 ns pulses. A nonlinear grating coupler analysis identifies the subpicosecond and picosecond processes with electronic nonlinearity, but the dominant effect in the nanosecond experiment is due to thermal nonlinearity derived from weak absorptions. The magnitude and sign of n2 of electronic nonlinearity are measured.

    Notes: Leaf crinkle symptoms, stem necrosis and stunting were observed in Solanum capsicastrum plants in India. A virus was isolated from these plants and identified as a strain of eggplant mottled crinkle virus based on host reactions, in vitro properties, icosahedral particle morphology, buoyant density (1.39 g cm3), molecular weight (41 ± 0.5 kDa) of coat protein subunits and serological relationships

    Kinetics of Water Sorption by Soybean and Pigeonpea Grains (1987)

    Notes: Kinetics of liquid water sorption by soybean (Glycine max) and pigeonpea (Cajanus cajan) seeds was studied at several temperatures. The data could be accurately correlated in terms of an empirical model involving a single rate constant. The temperature dependence of the rate constant followed Arrhenius relation. Swelling of grains due to water sorption was slightly less than the volume of water imbibed. This loss related to the energy of activation of the water sorption process.

    In vivo effects of Sn-1,2-dioctanoylglycerol, TPA and A23187 on hamster cheek pouch epithelium (1988)

    Notes: Cheek pouches of male Syrian golden hamsters were topically treated with a single dose of TPA (.5 μg), calcium ionophore A23187 (75 μgs) or Sn-1,2-dioctanoylglycerol (DiC8) (500 μg) dissolved in 0.25 ml acetone. Acetone-treated animals served as controls. After 48 h the mitotic index for the control group was 1.1 ± 0.1 per 1 mm of the basement membrane length. All the test congeners exhibited higher mitotic indices than controls: TPA (4.8 ± 0.4), A23187 (3.9 ± 0.3), DiC8 (2.1 ± 0.2). All groups exhibited an increase in the epithelial thickness manifested by cellular hyperplasia. The treatment of the pouches with the anti-inflammatory agent fluocinolone acetonide inhibited the milogenic and hyperplasiogenic affects on the epithelium induced by the various test chemicals. These studies indicate a possible role of calcium-phospholipid dependent protein kinase (protein kinase C) in the mediation of oral epithelial cell proliferation.

    Notes: The management of public affairs in northeast India has been in focus in the regional, national and world press in recent years. Much of the attention has been confined to insurgency, the ‘foreign nationals’ issue, tribal ‘uprisings’, ‘brutalities’ committed by the security forces, ‘involvement’ of foreign agencies in the area, political ‘horse-trading’ and floods. There has been no analysis of the economic, cultural and demographic factors which have acquired different nuances in the wake of the rapid modernization taking place in the region since the 1950s and which have a decisive say on the formulation of policies and the efficacy of institutions of governance in northeast India. This paper proposes to offer some facts and reflections on these aspects.

    Notes: Summary Seventy-six uncomplicated hypertensive patients treated in General Practice, whose seated diastolic blood pressure (Phase V) (dBP) remained ≥95 mmHg after a minimum of 4 weeks treatment with metoprolol 50 mg b.i.d. as antihypertensive monotherapy, were randomized to receive the selective ‘calcium antagonist’ felodipine 5 mg b.i.d. or hydrochlorothiazide 12.5 mg b.i.d. in addition to metroprolol 50 mg b.i.d. The trial duration was 8 weeks, the dose of the felodipine or hydrochlorothiazide being doubled after 4 weeks if ‘control’ of BP (dBP 〈90 mmHg) was not achieved on the initial doses. Over the trial period of 8 weeks, felodipine reduced dBP from 102 to 85 mmHg and hydrochlorothiazide from 101 to 91 mmHg; the dBP reduction in the felodipine group was greater than that in the hydrochlorothiazide group (17 vs 9 mmHg) and the attained dBP lower in the felodipine group. About half of the patients in each group required the higher dose. Both regimes were effective and well tolerated. In the dosages used, felodipine was a slightly more effective antihypertensive drug than hydrochlorothiazide when added to metoprolol. There was no apparent difference in the tolerability of the two regimes.
