Atmospheric photodissociation lifetimes for nitromethane, methyl nitrite, and methyl nitrate
(Wiley: International Journal of Chemical Kinetics, 1980-04)
Atmospheric photodissociation rate coefficients and photodissociation lifetimes for nitromethane, methyl nitrite, and methyl nitrate were calculated as a function of altitude from their measured visible and near ultraviolet ...
Crayfish hepatopancreas peroxidase: Absence of a microbicidal function
(Elsevier: Journal of Invertebrate Pathology, 1980-03)
Experimental investigation of the resistance in thin superconducting films of niobium-germanium
(American Institute of Physics, 1980-01-15)
We discuss the resistance of thin superconducting films of amorphous niobium-germanium below the BCS thermodynamic transition temperature as determined by measurements of the heat capacity. This resistance is shown to be ...
Purification of human myeloperoxidase by Concanavalin A-Sepharose affinity chromatography.
(Marcel Dekker: Preparative Biochemistry, 1980)
Myeloperoxidase (E.C. 1.11.1.7. Donor: H2O2 oxidoreductase), an enzyme of the azurophil granule of polymorphonuclear leukocytes, has been purified from the blood of a single human donor. Leukocytes were harvested by dextran ...
Blood oxygen transport and delivery in reptiles
(Oxford University Press: American Zoologist, 1980)
Cenozoic reptiles are characterized by physiological morphological and ecological systems with low energy requirements compared to those of mammals. Ectothermy and low resting rates of metabolism are the primary physiological ...
Chemical carcinogen in vitro testing: a method for sizing cell nuclei in the nuclear enlargement assay
(Elsevier: Toxicology, 1980)
The observation that cells often respond to carcinogens by nuclear enlargement has suggested that this property might be useful to develop a short-term screening test for such compounds. Previous methods for detecting ...
The Advantages of ectothermy for tetrapods
(University of Chicago Press: American Naturalist, 1980-01)
The way of life of amphibians and reptiles, in contrast to that of birds and mammals, is based on low energy flow. Many of the morphological and physiological characteristics of ectothermal tetrapods that are normally ...
Properties of segmented polyether poly(urethaneureas) based of 2,4-toluene diisocyanate. 2. Infrared and mechanical Studies
(American Chemical Society: Macromolecules, 1980-01)
: IR spectra of two series of polyether poly(urethaneureas) based on 2,4-toluene diisocyanate, ethylenediamine, and either 1000 or 2000 molecular weight poly(tetramethy1ene oxide) were examined first to elucidate the state ...
