    Notes: Summary The effect of three pesticidesviz, simazine, lindane and ceresan upto 100-fold of field application was studied on organic matter mineralization as well as on nitrification rates in Delhi alluvial soil. The normal rate of simazine (2 ppm) did not influence CO2 evolution but higher concentrations suppressed it. Lindane and ceresan inhibited CO2 production from soil by normal concentrations but the same CO2 production was enhanced in berseem roots treated soil upto 10 ppm of ceresan. The nitrification of ammonium sulphate in soil due to these pesticides was impaired significantly for varying periods. The inhibitory effect of higher concentrations was marked only upto 3 weeks, subsequently the rate of nitrification was restored. Among the nitrifiers, Nitrobacter were more susceptible as compared to Nitrosomonas.

    Notes: Abstract In this paper, the flow of a visco-elastic liquid between two parallel plates has been studied when one plate is stationary and the other plate suddenly starts oscillating. Both finite Fourier sine transform and Laplace transform technique have been employed to solve the basic differential equations. The flow phenomenon has been characterized by the parametersα, β andω and the effects of these on the flow characteristics have been studied through several graphs.

    Notes: Abstract Ascorbic acid levels of seven species of digenetic trematodes, living under different environmental conditions in fish and mammals were determined colorimetrically. Ascorbic acid levels ranged from 0.312 mg/100 g fresh weight inGastrothylax crumenifer to 5.070 mg/100 g fresh weight inFasciola indica. Low levels of ascorbic acid were detected in the rumen parasites and inIsoparorchis hypselobagri. In contrast the liver parasites were found to have relatively high ascorbic acid levels.
