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 ...
Biased Cold Dark Matter Theory - Trouble from Rich Clusters
(Univ Chicago Press, 1989-06-15)
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 ...
Generation of theta rhythm in medial entorhinal cortex of freely moving rats
(Elsevier, 1980-05-05)
A regular slow wave theta rhythm can be recorded in the medial entorhinal cortex (MEC) of freely moving rats during voluntary behaviors and paradoxical sleep. Electrode penetrations normal to the cortical layers proceeding ...
Amino acid substitution and chemical characterization of a Japanese variant of carbonic anhydrase I: CA I Hiroshima-1 (86 Asp → Gly)
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1981-06)
An electrophoretic variant of red cell carbonic anhydrase I, designated CA I Hiroshima-1, has been observed in 12 apparently unrelated individuals during a survey of 13,019 individuals from the cities of Hiroshima and ...
Role of gangliosides in gonadotropin and cholera enterotoxin stimulated steroidogenesis in isolated rat ovarian cells
(Elsevier, 1978-07-28)
Ovarian cells isolated from 26 day old rats responded to hCG (10 ng/ml) and cholera enterotoxin (100 ng/ml) with a forty-five to fifty-fold increase in progesterone production. Both cholera enterotoxin and hCG-stimulated ...
