Collision cross-section determination of isomeric carotenoids using electrospray ion mobility time-of-flight mass spectrometry

Introduction Carotenoids are naturally occurring pigments that function as provitamin A compounds and antioxidants. Biosynthesized in plants as the all-trans isomers, carotenoids undergo isomerization to form multiple cis isomers which have been reported to have different bioavailabilities [1]. Although C30 stationary phases are available to facilitate the chromatographic separation of caroteno...

Time-Series–Cross-Section Methods

Time-series–cross-section (TSCS) data consist of comparable time series data observed on a variety of units. The paradigmatic applications are to the study of comparative political economy, where the units are countries (often the advanced industrial democracies) and where for each country we observe annual data on a variety of political and economic variables. A standard question for such stud...

Measurements of the neutron - proton and neutron - carbon total cross section from 150 to 800 keV

A N ABSOLUTE DETERMINATION OF THE ~35U FISSION CROSS SECTION AT 964 keV*

-An absolute measurement of the 235U fission cross section has been carried out using a S4Na-Be photoneutron source with median neutron energy of 964 keV. A symmetric two-foil experiment was set up to measure the fission rate in a low-albedo laboratory, and variations in the sourceto-foil spacing used to determine the room background. Fission fragments passing through a limited solid angle aper...
