    Proposed experimental studies for assessing ionospheric perturbations on SPS uplinking pilot beam signal (1980)
    In:  CASI
    Details
    Publication Date: 2019-06-28
    Description: Evidence is presented for the occurrence of natural irregularities at midlatitude based on scintillation measurements by the use of VHF and GHz transmission from geostationary satellites, and from satellite in-situ measurements. An effort to determine the phase and intensity scintillation effects during ionospheric heating is described along with proposed measurements related to the detection, lifetimes, and drift of artificial irregularities generated by ionospheric heating in the underdense mode.

    Proposed experimental studies for assessing ionospheric perturbations on SPS uplink pilot beam signal (1980)
    In:  Other Sources
    Details
    Publication Date: 2019-06-28
    Description: The microwave beam of the proposed Solar Power Satellite (SPS) at geosynchronous altitude is to be formed and directed by phase information derived from a pilot signal at 2.45 GHz transmitted from ground and received in a number of module locations on the SPS antenna. The frequency of the pilot signal was chosen to be sufficiently low as to avoid the effects of strong scattering by turbulence in the neutral atmosphere and yet high enough to avoid any possible refractive effects caused by the ionized upper atmosphere. The propagation of the uplink pilot signal through the ionosphere which contains natural and possibly some artificial irregularities, was studied.

    Surimi based dried fish cake (2021)

    Description: Minced fish prepared from the fillets of the sciaenid fish (Lutjanus sp.) was washed with cold water (〈10 °C) three times. The washed muscle was pressed through a piece of fine cloth to a moisture content around 80%. The pressed cake (Surimi) was ground with 2.5% sodium chloride and 3% tapioca starch. The mixed material was shaped in the form of a cake and left for one hour for the gel to set. The cakes were then steamed. The cooled cakes were cut into pieces of 1 cm length x 1 cm width x 0.5 cm thick. The pieces were either dried in an electrical oven at 50°C or dried in sun to a moisture content of 11-12%. Biochemical, bacteriological and organoleptic evaluation revealed that the cakes were in very good acceptable form for 8 months. The cakes could be rehydrated by soaking in water at ambient temperature for half an hour and boiling in water for 10 minutes.

    Antibacterial effect of the Indian squid, Loligo duvauceli (d'Orbigny), ink (2021)
    In:  http://aquaticcommons.org/id/eprint/16592 | 12051 | 2015-04-08 18:51:13 | 16592 | Indian Fisheries Association

    Publication Date: 2021-07-07
    Description: The ink of the Indian squid Loligo duvauceli (d'Orbigny) was tested for antibacterial activity. The antibacterial effect of bacteria present in the ink gland was also tested. Only one type of bacteria was found to be present in the ink gland of squid and was identified as Photobacterium leiognathi. Among the various forms of ink extracts, the precipitated and freeze-dried ink showed more pronounced antibacterial effect against Gram-negative bacteria, Salmonella, spp. Escherichia coli, Vibrio cholerae, V. parahaemolyticus and Pseudoinonas spp., and a less pronounced effect against Gram-positive bacteria, Staphylococcus spp. and Micrococcus spp., P. leiognathi did not inhibit any of the above bacteria. The antibacterial activity was associated with the compounds of the ink.

    Publication Date: 2011-08-27
    Description: Author(s): N. S. Sangeetha, A. Thamizhavel, C. V. Tomy, Saurabh Basu, S. Ramakrishnan, and D. Pal We report on the detailed magnetic properties of polycrystalline ternary rare-earth intermetallic stannide compounds R 2 Ir 3 Sn 5 ( R = La–Nd, Gd–Tm). Except for La 2 Ir 3 Sn 5 , all the other compounds of R 2 Ir 3 Sn 5 ( R = Ce–Nd, Gd–Tm) crystallize in the orthorhombic Y 2 Rh 3 Sn 5 (Cmc2 1 ) type structure. La 2 Ir 3 Sn 5 cry... [Phys. Rev.
