Transition-metal eight-coordination. 13. Synthesis, characterization, and crystal and molecular structure of the schiff-base chelate bis( N,N'-disalicylidene- 1,2-phenylenediamino) zirconium(IV) benzene solvate
(The American Chemical Society: Inorganic Chemistry, 1979-10)
As part of our program to elucidate eight-coordinate complexes and their polymeric counterparts we have isolated and structurally characterized the model Schiff-base chelate bis(N,N'-disalicylidene-1,2-phenylenediamino)z ...
Hysteresis behavior in polyether poly(urethaneureas) based on 2,4-toluene diisocyanate, ethylenediamine, and poly(tetramethy1ene oxide)
(American Chemical Society: Macromolecules, 1979-05)
Dynamical systems characterized by automata
(Springer Wien, 1979-03)
Automata and Dynamical Systems Theory both rest on a common mathematical structure. In this work the interrelation between these theories is studied, starting with a simple characterization of a dynamical system (and some ...

The effect of rattlesnake venom on digestion of prey
(Elsevier: Toxicon, 1979)
Rattlesnake venom injected into live mice before they were swallowed by non-venomous snakes speeded the process of digestion. This effect of venom was more pronounced when digestion was tested at 15°C than at 25°C. The ...
W-reactivation of phage lambda in recF, recL, uvrA, and uvrB mutants of E. coli K-12
(Springer: Molecular and General Genetics, 1979-01)
W-reactivation is reduced by recF143 and recF144 mutations and is undetectable if a second mutation at either the uvrA or uvrB locus is combined with recF143. The uvrA and uvrB mutations alone block W-reactivation partially. ...
A comparative study of ethidium bromide complexes with dinucleotides and DNA: direct evidence for intercalation and nucleic acid sequence preferences
(The Americal Chemical Society: Biochemistry, 1978-11-14)
The relative fluorescence quantum yields of ethidium bromide solutions with deoxyribodinucleoside monophosphates have been measured and found to correlate with similar data for the binding of ethidium to DNA. The fluorescence ...
Photoabsorption spectra of gaseous methyl bromide, ethylene dibromide, nitrosyl bromide, thionyl chloride, and sulfuryl chloride
(The American Chemical Society: The Journal of Physical Chemistry, 1978-10-05)
The photoabsorption spectra of some molecules of atmospheric interest, CH3Br, BrCH2CH2Br, BrNO, SOCl2, and SO2Cl2, were quantitatively investigated over the wavelength region from 190 to 300 nm at 295 K and were found to ...
Metabolism and activity of the spanish fringe-toed lizard (Lacertidae: acanthodactylus erythrurus)
(Elsevier: Journal of Thermal Biology, 1978-10)
1.In the field, adult fringe-toed lizards (Acanthodactylus erythrusus) had a mean body temperature of 38.8 ± 0.2 (S.E.) °C while subadults maintained a significantly lowr temperature (x average = 35.4 +/- 0.5 degrees ...
Comparison of the electronic transitions of unconjugated thiones and imines: an exercise in the application of symmetry selection rules
(The American Chemical Society: Journal of Chemical Education, 1978-08)
The purpose of this paper is to show how symmetry selection rules can be used to determine whether certain of the electronic transitions exhibited by the title compounds are allowed or forbidden by symmetry.
