As the biological effect of nicotine on lymphocyte is dependent on dose of nicotine, the duration of exposure[ 37], and the LPS existence in experiment system [ 20], the controversy of nicotine's effect on DCs might be attributed to the differences of experimental design, species, duration of exposure, and especially the nicotine concentration used in these experiments.
The longest experiment in existence is the Park Grass Experiment, which was initiated in 1856.
Indeed, we have seen that he adopted an operational "measurement=meaning" principle according to which the meaningfulness of a physical quantity was equivalent to the existence of an experiment purporting to measure that quantity.
Nearly all of the as-prepared samples were hollow spheres with good quality under the effect of Eu3+ and Sm3+ existence, and the experiments showed good reproducibility and satisfactory results.
Very few in existence, mainly an "experiment".
While those particles are not predicted by the Standard Model and have never been seen directly in an experiment, their existence would not surprise theorists.
By D. McKenzie, Andy Logan, and Russell Maloney The New Yorker, January 29 , 1944P. 13 Talk story about Professor Felix Ehrenhaft, who announced at a recent meeting of the American Physical Society, that he had proved by experiment the existence of a pure magnetic current.
The other, even more compelling, concerns candy itself: how some of the brands we remember so vividly — Abba-Zaba bars, Peeps — owed their existence to the kitchen experiments of immigrants.
Instead, qualitative descriptions of experiments and existence proofs (i.e. unvalidated experimental results) are the norm.
In order to attain good agreement with experiments, the existence of carbon-rich austenite films adjacent to bainitic ferrite plates is posited.
