    Notizen: An experimental setup for studying the influence of the radial electric field on very low qa plasma on the Saha Institute of Nuclear Physics tokamak is presented. A high current, high voltage pulsed power supply, using a semiconductor controlled rectifier (SCR) as a dc switch is developed and used to bias a tungsten electrode inserted inside the plasma. The electrode's exposed length and its position inside the plasma are controlled by a double bellows assembly to optimize the electrode-exposed length. We show that using the force commutation method to turn the SCR off to get the power pulse desired has good potential for carrying out similar kinds of studies, especially in a low budget small tokamak. © 1999 American Institute of Physics.

    Notizen: Abstract— Adenosine triphosphatase (ATPase) activities of brain microsomal and synaptosomal preparations are inhibited by imipramine [5-(3′-dimethylamino propyl)-10, 11-dihy-dro-5H-dibenz (b,f) azepine] in vitro, whereas microsomal ATPase activity is stimulated and synaptosomal ATPase activity remains unaltered under in vivo imipramine treatment. The inhibition of ATPase activity can to some extent be counteracted by spermine [N, N′-bis(3 aminopropyl)-1,4-butanediamine]. Determination of Km values from double reciprocal plots (activity-1 vs. ATP mM-1) under drug and spermine-treated conditions appear to indicate that spermine can to some extent imparta stabilizing effect mainly on the microsomal membrane ATPase, preventing inhibition in presence of imipramine in vitro, although spermine has no effect on the already destabilized membrane ATPase. Spermine exerts a stabilizing effect on membrane ATPase possibly by increasing the affinity of the enzyme for the substrate.

    Notizen: Abstract In a multiparameter set-up, this paper characterizes priors which ensure frequentist validity, up too(n −1), of confidence regions based on the highest posterior density. The role of Jeffreys' prior in this regard has also been investigated.

    Notizen: Abstract  A field experiment was conducted to study the effect of arbuscular mycorrhizal association in mulberry saplings var. S1, together with two levels of phosphate, on growth characters, leaf yield and phosphorus uptake. The experiment was conducted in the period 1995 to 1997 at the Technical Service Centre, Kashipur, Purulia (West Bengal) under rainfed, lateritic soil conditions. Pooled data analysis revealed that there was no significant variation among the treatments in most of the characters except height of plant and leaf moisture percentage. Plant height in both treatments with Glomus mosseae was significantly less than in the others, while there was significant reduction in moisture percentage in G. fasciculatum with 25 kg of phosphate and G. mosseae with 10 kg of phosphate ha–1 year–1 than in other treatments. There was no significant season–treatment effect on any of the parameters. Considering all the quantitative and qualitative characters, G. fasciculatum together with the most economic dose of phosphate showed more promising performance than G. etunicatum and G. mosseae with different doses of phosphate fertilizer. At 80% of the recommended dose of inorganic phosphate fertilizer, Rs 534.0 were earned as net profit.

    Notizen: Summary X-Ray radiography was employed to monitor the diffusion of sucrose into plaster of Paris matrix containing 20% yeast cells. It was observed that the depth of penetration of tracer Pb detected by radiography matched with the substrate penetration detected by chemical test. However electron probe microanalysis (EPMA) did not yield any conclusive evidence regarding the movements of tracer Pb and substrate to the same extent.
