John Archibald Wheeler (09 July 1911- ) is a familiar name to physicists and historians of physics alike. Among his many contributions to the corpus of knowledge, in 1939 John Wheeler and Niels Bohr co-authored the first paper on the generalized mechanism of nuclear fission. Beyond that seminal work, Wheeler...
A fossil-calibrated phylogenetic framework based on exemplars from each of the four taxonomic sections within Pinus was created using multiple nuclear and chloroplast loci. Calibration at the well-defined subgeneric split within Pinus with either fossil leaves and cones (ca. 45 million years ago) or fossil wood (ca. 85 million years...
7,7'-Dihydroxy-8,8'-biquinolyl (azaBINOL) was prepared from 7-hydroxyquinoline via N,N-dimethyl O-quinol-7-yl carbamate by directed ortho-metallation followed by FeCl₃-mediated oxidative coupling of the 8-lithioquinoline intermediate. Saponification of the resulting dicarbamate provided crystalline (±)-azaBINOL in 56% overall yield. 6,6'-Bis(dimethylaminocarbonyl)-7,7'-dihydroxy-8,8´-biquinolyl was prepared from the same dicarbamate by a double anionic-Fries rearrangement in 43% yield. 7,7'-Bis(diethylamino-carbonyloxy)-6,6'-diiodo-8,8´-biquinolyl...
The atomic age was enacted by many scientists as a way to realize health and human rights. Human rights were conceived in this context as rights to economic development, science education, and nuclear medicine. The United States Atomic Energy Commission (AEC) acted hand in hand with UN agencies and educators...
In 1746, Dr John Buchanan, a recently retired medical officer in the British Army, produced a manuscript, 'Regimental Practice, or a Short History of Diseases common to His Majesties own Royal Regiment of Horse Guards when abroad (Commonly called the Blews).' Revised almost until the time of Buchanan's death in...
This analysis is the study of Oregon's wildlife resources from
the period prior to white settlement up to the present time, including
critical projections, based on present trends and expected conditions
for both human and wildlife populations in the state up to the year 2010.
Prior to white settlement Oregon...
A biographical study of Denison Olmsted, focusing upon his
own Christian world view and its connection with his various
activities in science, supports the view that religion served as a
significant factor in the promotion of science in America during this
time period. Olmsted taught physics, meteorology and astronomy
at...
