Sampling and extra-column effects in high-performance liquid chromatography; influence of peak skew on plate count calculations.

Journal of chromatographic science

Kirkland JJ, Yau WW, Stoklosa HJ, Dilks CH.
PMID: 893648
J Chromatogr Sci. 1977 Aug;15(8):303-16. doi: 10.1093/chromsci/15.8.303.

Chromatographic resolution and analysis accuracy can be seriously affected by broadening of very sharp bands associated with both high-performance size-exclusion chromatography and other liquid chromatography methods using less than 5 micron particles. The effect on column plate count by...

Glacial legacies on interglacial vegetation at the Pliocene-Pleistocene transition in NE Asia.

Nature communications

Herzschuh U, Birks HJ, Laepple T, Andreev A, Melles M, Brigham-Grette J.
PMID: 27338025
Nat Commun. 2016 Jun 24;7:11967. doi: 10.1038/ncomms11967.

Broad-scale climate control of vegetation is widely assumed. Vegetation-climate lags are generally thought to have lasted no more than a few centuries. Here our palaeoecological study challenges this concept over glacial-interglacial timescales. Through multivariate analyses of pollen assemblages from...

Recruit Retent Restruct Rep. 1997 Jan-Feb;10(1):1-3.

During this period of low patient census, downsizing, and reorganization, nurses already complain they do not feel respected. Expanding competency evaluations only adds to this feeling that others do not respect the professional nurse. These authors describe strategies to...

Environ Pollut. 1996;91(3):279-82. doi: 10.1016/0269-7491(95)00074-7.

In Britain, polecats Mustela putorius hunt around farm buildings, especially in winter, and, as a result, may be secondarily exposed to rodenticides by eating contaminated prey. This paper reports the first survey of second-generation rodenticides in polecats. Twenty-nine adult...
