    Notes: Abstract The paper discusses seasonal variation in the energy contents of four macrobenthic invertebrates of Lake Nainital during 1977–78. The energy values varied from 16971–19437 J/g dry weight in Tubifex tubifex, 16 511–20 231 J/g dry weight in Glossiphonia weberi, 19 019–25 289 J/g dry weight in Chironomus plumosus and 19 583–20 549 J/g dry weight in Viviparus bengalensis. The former two genera exhibited highest energy contents during summer, whereas the latter two revealed highest values during winter. On mean annual basis, the highest values were recorded for C. plumosus and lowest for T. tubifex. In V. bengalensis, variation occurred in ash fraction (%) and in energy values (Joule per gram dry weight) but not in energy values of organic fraction (Joule per gram ash-free dry weight), while the other three genera displayed variation in all three variables.

    An energy budget for Simocephalus vetulus (O. F. Muller) (Crustacea : Cladocera) (1984)

    Notes: Abstract We discuss the energetics of a cladoceran, Simocephalus vetulus at different temperatures (8.0 ± 1.0, 15.0 ± 1.0, 21.0 ± 1.0 and 28.0 ± 1.0 °C) and food (Chlamydomonas sp.) concentrations (25 × 103, 50 × 103, 75 × 103 and 100 × 103 cells ml−1). Increase in temperature accelerated ingestion and, to some extent, oxygen consumption. The study revealed a high reproduction efficiency in S. vetulus. Net growth efficiency (ECI) was higher (13.17–41.18%) in pre-adults than in adults (2.71–8.40%). The assimilated energy (A) increased with increasing food concentration at all temperatures. Assimilation efficiency (AD) decreased with increasing food concentrations. The energy used for growth (P) was nearly constant at all food levels because the egested energy increased and assimilation efficiency decreased as food concentration increased.

    Macrobenthos of Lake Naini Tal (U.P., India) with particular reference to pollution (1983)
    Springer
    Water, air & soil pollution 19 (1983), S. 397-405 
    Details
    ISSN: 1573-2932
    Source: Springer Online Journal Archives 1860-2000
    Topics: Energy, Environment Protection, Nuclear Power Engineering
    Notes: Abstract The important attributes of macrobenthic community structure viz., species composition and number, population density, biomass, and dominance and diversity indices were measured at different depths and discussed in relation to pollution of Lake Naini Tal. The zone below 7 m depth, where anoxic conditions prevailed for most part of the year, showed complete absence of macrobenthos.

    Tessier number two cleft (1989)

    Notes: Summary The number two craniofacial cleft as described by Tessier is an extremely rare cleft of unknown etiology with distinct soft tissue and bony characteristics. It traverses the alveolar arch at the level of lateral incisor, middle third of the alar rim, the junction between the nasal bone and the frontal process of maxilla and medial end of the eyebrow and continues cranially as a number 12 cleft. Two such patients with interruption of the middle third of alar rim and asymmetrical hypertelorism are described.
