An extensive survey of radioimmunoassay calibration data for prednisolone, prednisone and digoxin indicated that the common practice of preparing calibration curves with individual subject's pre-dose plasma or serum, and using this to estimate unknown concentrations for the same subject, is not supported by statistical considerations. Preparation of calibration plots from pooled data is better ...

Rainfall data from the year 1965 to 2005 have been analyzed and then plotted with respect to time to analyze time series plot and autocorrelation plot.. From the autocorrelation plots, it is observed that upto lag 4 to lag 5, which is around 10% of the length of the data, the results shows better correlations and for lags beyond 10% of the record length, there exist less correlation and more va...

Breeding site selection can be linked to population dynamics through pre-emptive site selection, by which an individual selects the best (in terms of fitness) available site, preventing others from sharing it. We examined the pattern of territorial settlement and its fitness consequences during a study of sedge warblers Acrocephalus schoenobaenus inhabiting two study plots in the Nida Wetlands ...

The commonest method of characterizing a cold field electron emitter is to measure its current-voltage characteristics, and the commonest method of analysing these characteristics is by means of a Fowler-Nordheim (FN) plot. This tutorial/review-type paper outlines a more systematic method of setting out the Fowler-Nordheim-type theory of cold field electron emission, and brings together and sum...
