An investigation of mortality with IBM 650
Scandinavian Actuarial Journal, 1961Abstract During the period 1953/2-1956 an investigation of the mortality of standard risks for the years 1948/2-1952 was made in Finland. This investigation resulted in a renewal. of the bases of calculation in 1957 for all Finnish life companies. With certain aggravations these bases were applied also to substandard risks, but there was not a sound ...

STRUCTURES OF CHLOROBIUM CHLOROPHYLLS (650)
Canadian Journal of Chemistry, 1965The structures of six Chlorobium chlorophylls (650) have been determined. The pheophorbides are derivatives of 2-desvinyl-2-α-hydroxyethyl pyropheophorbide a. Variation of the substituents at C4 (isobutyl, n-propyl, or ethyl) and C5 (ethyl or methyl) accounts for the six different compounds.

2008 IEEE International Vacuum Electronics Conference, 2008
The operational frequency of helical vacuum electron devices has always been limited by the ability of conventional technology to fabricate very small helices, and by the difficulty of passing a meaningful current through the center of such a small structure.

The Kingdom of the Deirans, 450–650
2018Chapter 1 considers the formation and organization of the kingdom of the Deirans during the period 450–650 as a context for conversion. It reconstructs the formation of the kingdom, and the social institutions and religious beliefs of its population, from a combination of fifth- to seventh-century mortuary archaeology and early eighth-century histories.
