Rotational energy dispersions: Analytic descriptions
(Elsevier, 1992-09)
Closed-form analytic expressions parametric in the centrifugal displacement are presented for the dependence of the classical rotational energy of a harmonic oscillator (HO), Morse oscillator (MO), and Lennard-Jones 6-12 ...
Replication of mini-F plasmids during the bacterial division cycle
(Elsevier, 1992)
The cell-cycle replication patterns of two mini-F plasmids have been examined using the membrane-elution technique (to produce cells labelled at different times during the division cycle) and scintillation counting (for ...
Radiation hybrid map spanning the huntington disease gene region of chromosome 4Radiation hybrid map spanning the huntington disease gene region of chromosome 4
(Elsevier, 1992-08)
Radiation hybrid (RH) mapping was used to construct a map of 11 markers in the distal 4 Mb of the short arm of chromosome 4, the region containing the Huntington disease gene. Two different methods for deriving the order ...
Lamellocyte differentiation in Drosophila larvae parasitized by Leptopilina
(Elsevier, 1992)
The presence of Leptopilina heterotoma or Leptopilina boulardi eggs in the hemocoel of a Drosophila melanogaster larva induces the differentiation of lamellocytes, the blood cells that encapsulate foreign objects. L. ...
The use of sulfide cluster-derived catalysts to understand the promotional effect in hydrotreatment catalysis
(John Wiley & Sons Ltd., 1992-09)
Sulfide cluster-derived ensembles are promising models of the active sites in commercial hydrotreatment catalysts. A series of sulfide clusters were adsorbed intact onto high-surface-area Γ-alumina, magnesium oxide and ...
The in vivo and in vitro genotoxicity of aromatic amines in relationship to the genotoxicity of benzidine
(Elsevier, 1992-08)
Benzidine and 12 related aromatic amines have been studied for the effects of substituent groups and [pi] orbital conjugation on their genotoxicity as measured by their mutagenicity in vitro with Salmonella and by chromosomal ...
Pharmacological profile of a potent, efficacious fentanyl derivative in rhesus monkeys
(Springer-Verlag, 1992-11)
The recent synthesis of fentanyl derivatives, some of which appear to have novel profiles of pharmacological effects, has provided compelling evidence that μ opioid efficacy might be altered systematically by modifications ...
Redox properties of the iron-sulfur clusters in activated Fe-hydrogenase from Desulfovibrio vulgaris (Hildenborough)
(Blackwell Publishing Ltd, 1992-10)
