Other examples include various prescription drugs ( e. g. most antiepileptic drugs have cerebellar ataxia as a possible adverse effect ), Lithium level over 1. 5mEq / L, cannabis ingestion and various other recreational drugs ( e. g. ketamine, PCP or dextromethorphan, all of which are NMDA receptor antagonists that produce a dissociative state at high doses ).

After passing Af through DEAE-cellulose, the titer of antibodies to WTV in the specific fraction was 1: 4 of the titer before such passage ( precipitin ring tests by R. F. Whitcomb ) ; ;

but mere dilution of the conjugate to 1: 4 did not satisfactorily remove nonspecific staining.

For an experiment to qualify as a binomial experiment, it must have four properties: ( 1 ) there must be a fixed number of trials, ( 2 ) each trial must result in a `` success '' or a `` failure '' ( a binomial trial ), ( 3 ) all trials must have identical probabilities of success, ( 4 ) the trials must be independent of each other.

For example, the marksman gets 5 shots, but we take his score to be the number of shots before his first bull's-eye, that is, 0, 1, 2, 3, 4 ( or 5, if he gets no bull's-eye ).

Since accurate base maps are necessary for any planning program, the first step taken by the planning division to implement the long-range state plan has been to prepare two series of base maps -- one at a scale of 1 inch to a mile, and the second a series of 26 sheets at a scale of 1 inch to 2000 feet, covering the entire state.
