THE LIFE HISTORY OF COLEOCHAETE SCUTATA (CHLOROPHYCEAE) STUDIED BY A FEULGEN MICROSPECTROPHOTOMETRIC ANALYSIS OF THE DNA CYCLE 1, 2
(Blackwell Science Inc, 1976-03)
The life history of Coleochaete scutata BrÉb. was analyzed by Feulgen microspectrophotometry, a technique measuring DNA content in individual nuclei. By correlating nuclear DNA content with morphological structures or ...
Observations on the habitat of Pogonia ophioglossoides (Orchidaceae) in Northern Michigan.
(1997)
In conclusion, observation of Pogonia ophioglossoides, the rose pogonia or snake's mouth orchid, appears to indicate that it is a moisture-loving, calciphilic, minerotrophic fen species which grows on the quaking mat, poor ...

β-funaltrexamine antagonizes the discriminative stimulus effects of morphine but not naltrexone in pigeons
(Springer-Verlag, 1987-02)
Antagonistic actions of the irreversible, μ-selective antagonist β-funaltrexamine (β-FNA) were evaluated in pigeons trained to discriminate among intramuscular injections of morphine (5.6 mg/kg), saline, and naltrexone ...
A revised model for the density and thermal expansivity of K 2 O-Na 2 O-CaO-MgO-Al 2 O 3 -SiO 2 liquids from 700 to 1900 K: extension to crustal magmatic temperatures
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 1997-12)
A revised model for the volume and thermal expansivity of K 2 O-Na 2 O-CaO-MgO-Al 2 O 3 -SiO 2 liquids, which can be applied at crustal magmatic temperatures, has been derived from new low temperature (701–1092 K) density ...
Equilibrium-limited periodic separating reactors
(American Institute of Chemical EngineersWiley Periodiocals, Inc., 1987-08)
A new unit operation is presented that utilizes a rapid feed pressure swing cycle in a bed packed with catalyst and adsorbent to effect both reaction and separation. This hybrid device combines features of a cyclic-steady-state ...
