Early Computing at the University of Alberta and the Introduction of the LGP-30
To re-create the University of Alberta's computing milieu of some 40 years ago, this article surveys the university's computational procedures before the arrival of the first computer and discusses the university's acquisition and use of the LGP-30
EFFECT OF CROPPING SYSTEMS AND FERTILIZERS ON MEAN WEIGHT-DIAMETER OF AGGREGATES OF BRETON PLOT SOILS
Aggregate analyses of Breton plot soils using a wet sieving technique revealed marked differences resulting from cropping practices but few, if any, due to fertilizers. The mean weight-diameter of soils from plots in a 5-year rotation of grains and legumes was almost double the diameter of soils from plots in a wheat-fallow sequence. With respect to fertilizers, however, mean weight-diameter of soils from high yielding plots in either cropping system were in general similar to those on low-yielding plots of the system in question. Incidentally polysaccharide content of the soil showed a definite relationship to mean weight-diameter.
Repressive coping before and after diagnosis of breast cancer
Objective: The aim was to investigate to which extent emotional repression is a premorbid coping tendency of cancer patients and/or a coping response to the threat posed by a cancer diagnosis. The results of one previous study of breast cancer patients suggest the latter possibility, and our aim was to replicate and extend these findings.
