Biochemical Properties Of Salmonella Potsdam Bacteriophage P4/2, Clyde L. Roggenkamp
Loma Linda University Electronic Theses, Dissertations & Projects
Over 90% recovery of phage P4/2 was realized with differential centrifugation concentration and purification, whereas only about 16% was recovered from the aqueous two-phase polymer - Genetron - ECTEOLA-cellulose column system. Purity of preparations was greatest with the density gradient centrifugation (A260 = 2.66 and A280 = 1.80 per 1012 plaque-forming units). With the chemical system of concentration and purification followed by an ECTEOLA anion exchange run, the A260 was 6.6 and the A280 was 4.3.
Three tests were employed to determine the configuration of P4/2 DNA: (1) a formalin denaturation test, (2) a thermal …

Twinning Increases Production, K P. Croker
Twinning Increases Production, K P. Croker
Journal of the Department of Agriculture, Western Australia, Series 4
Many breeders claim that twinning causes too many losses among Merino lambs and does not favour breeding for twin lamb production.
But recent experiments have proved otherwise and agricultural scientists now agree that . . .
TWINNING INCREASES PRODUCTION
THE low marking percentages regularly recorded for Merino flocks suggest that the Merino is a relatively infertile breed.
Certainly, lambing percentages are low when compared with those of most British breeds of sheep.

Aspen Bibliography
The Department of Forestry has been carrying on silvicultural research in the white spruce (Picea glauca (Moench) Voss) and trembling aspen (Populus tremuloides Michx.) cover types in the Mixedwood Forest Section of Alberta, Saskatchewan and Manitoba for about 40 years. Because of the needs of industry most of this research has been focused on spruce, and only as small portion on aspen. Much of the research is concerned with basic problems and the findings in one area may be applied directly or with minor modification throughout the entire Mixedwood Forest Section. Only a minor part of the total …
