    O2 uptake through water during early life of Heteropneustes fossilis (Bloch) (1981)
    Springer

    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.

    Oxygen uptake through water during early life of Anabas testudineus (Bloch) (1979)
    Springer
    Hydrobiologia 66 (1979), S. 129-133 
    Details
    ISSN: 1573-5117
    Keywords: Metabolism ; oxygen uptake ; Respiration
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The O2 consumption (mg/hr) through water in case of Anabas testudineus during development and growth has been measured and its relationship to body weight or length studied. The logarithmic plot of 02 uptake through water either against body weight or length suggested a statistically significant (P 〉 3.53) two-component curve, the point of intersection being at 11 mg body weight and 1.78 cm body length. These are the theoretical values of weight or length at which the responsibility of supplementing nearly 40% of the total O2 demand through the newly developed air breathing organ falls in the early life of the fish. One of the impelling causes forcing developing fry of Anabas to adopt a bimodal gas exchange machinery seems to be 4 fold increase in the diffusion distance at the gills.

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

    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.

    Notes: Graft copolymerization of methyl methacrylate (MMA) was carried out on jute fibers using a V5+ -cyclohexanone redox initiator system. The effect of the concentration of acid, monomer, and V5+ on graft yield have been studied. In order to obtain optimum conditions of grafting, the effects of temperature, acid, reaction medium, solvent, and some inorganic salts on graft yield have been investigated. The most remarkable features of the investigation include the proposition of a mechanism and derivation of rate expression for the grafting process. More than 100% grafting could be achieved with the present system.

    Kinetics of retarded polymerization: Investigation of the retardation of V5+-thiourea initiated polymerization of methyl acrylate by phenol (1987)

    ISSN: 0887-624X

    Notes: The kinetics and mechanism of the retarding action of phenol on the V5+-thiourea initiated polymerization of methyl acrylate (MA) have been studied within the temperature range of 30-50°C. The effects of retarder (phenol), metal ion (V5+), monomer (MA), sulfuric acid, some organic solvents and inorganic salts on the percentage and rate of polymerization have been studied. The remarkable observation of the present study is the positive intercept obtained from the plot of [M]/Rp vs. 1/[M]. This type of observation is significantly different from previous studies on retarded polymerization. The values of composite rate constants k0kt/kikpkK have been calculated from plots of [M]/Rp vs. 1/[M]. On the basis of experimental findings a reaction mechanism has been suggested, and a suitable rate expression has been proposed and explained.

    Description / Table of Contents: Die Kinetik der Polymerisation von Acrylnitril in wäßriger Lösung mit Peroxodi-sulfat-Thioharnstoff als Redoxinitiator wurde im Temperaturbereich von 40-50°C erforscht. Der Einfluß der Konzentration von Thioharnstoff, Monomeren und Peroxodisulfat auf die Polymerisationsgeschwindigkeit als such auf den Umsatz wurde untersucht. Auch die Auswirkungen einiger anorganischer Salze und verschiedener oraganischer Lösungsmittel auf die Polymerisationsgeschwindigkeit wurde studiert. Die Untersuchung des isolierten Polymeren erfolgte mittels IR-Spektroskopie. Ein ge-eignetes kinetisches Schema wurde vorgeschlagen und ein pasender Geschwindig-keitsaudruck abgeleitet.
