The most serious disease problem in fraser fir (Abies fraseri) Christmas tree production is phytophthora root rot (PRR). The efficacies of six fungicide treatments in preventing PRR incited by Phytophthora cactorum and P. drechsleri in 2-year-old fraser fir seedlings were evaluated in 2010 and 2011 in central Pennsylvania. The study examined five fungicide drench treatments [dimethomorph, foset...

Fraser fir (Abics frmeri (Pursh) Poir.) is an endemic species consisting of six major disjunct populations in the Appalachian Mountains, U.S.A. Nuclear DNA content was measured with laser flow cytometry to determine if genome size differences could be detected among the disjunct populations of Fraser fir and its close relatives, balsam fir (Abies bnlsamea (L.) Mill.) and Canaan fir (A. balsamea...

Previous investigations in the literature have suggested a correlation between blood group A and carcinoma of the stomach (Fraser Roberts 1959). This finding was also present, but to a lesser degree, in cases of carcinoma of the oesophagus (Aird, Lee and Fraser Roberts 1960). Studies of the ABO blood group distributions of cancer within the remainder of the intestinal tract have not revealed an...

Jeffreys (1946) proposed a root-information prior for the likelihood analysis of a statistical model. Then for an exponential model with scalar parameter Welch & Peers (1963) showed that this leads to second-order inference, or more specifically that posterior intervals have second order confidence. But for an exponential model with vector-parameter Jeffreys (1961) found that the root informati...

Critical Issues Bulletins are published from time to time by The Fraser Institute (Vancouver, British Columbia, Canada) as supplements to Fraser Forum, the Institute's monthly periodical. Critical Issues Bulletins are comprehensive studies of single issues of critical importance for public policy. The author has worked independently and opinions expressed by him are, therefore, his own, and do ...
