    Notes: Abstract Extensive γ-γ coincidence measurements have been made on γ rays accompanying theβ − decay of214Bi using a conventional GeGe coincidence spectrometer. A total of 33 new γ transitions among levels of214Po have been established. Twenty-three previously reported but unplaced transitions have now been assigned in the level scheme. In addition to confirming 56 previously proposed levels, four new levels are established at 1015.05, 1712.98, 3003.5 and 3160.5 keV. Directional correlation measurements have been made on six weak cascades which have the first excited state in common. Mixing ratios have been deduced for the transitions concerned.

    Oxygen uptake through water during early life in Channa punctatus (Bloch) (Pisces; Ophicephaliformes) (1982)
    Springer

    Notes: Abstract Oxygen uptake in relation to body size during the early life of the fish Channa punctatus shows a significant two-component curve: one related to the fully aquatic phase and the other to the bimodal phase of respiration. The onset of the air-breathing habit around the 18–20th day after hatching brings about a 45% drop in O2 uptake through the gill/skin in water.

    O2 uptake through water during early life of Heteropneustes fossilis (Bloch) (1981)
    Springer
    Hydrobiologia 78 (1981), S. 81-86

    Topics: Biology
    Notes: Abstract The O2 uptake through water has been measured in case of Heteropneustes fossilis during development and growth and its relationship to body size established. A higher rate of O2 uptake during the early phase of ontogenesis is related to intense growth of the respiratory surface area and increasing metabolic demand of the fish. The logarithmic plot of data for O2 uptake in relation to body size shows a statistically significant two-component curve; one related to the fish when it is a fully aquatic breather and the other when it changes to bimodal gas exchange. The onset of the air breathing habit brings about a 40% drop in O2 uptake through water, which is made good through the newly developed air breathing organ.
