Salt excretion in a beach lizard (Ameiva quadrilineata, Teiidae)
(Springer: Journal of Comparative Physiology B: Biochemical, Systemic, and Environmental Physiology, 1976-01)
The teiid lizardAmeiva quadrilineata has a nasal salt gland that responds to NaCl loading by increasing excretion of Na+ (from 1.12 to 2.63 uM/100 gh), K+ (from 0.14 to 2.43 uM/100 gh), and Cl– (from 1.10 to 5.47 uM/100 ...
Stereochemistry and mechanism of ionic cyclopropane ring cleavage by arenesulfenyl chloride addenda in quadricyclene systems
(The American Chemical Society: The Journal of Organic Chemistry, 1975-10-17)
Addition of benzenesulfenyl chloride to quadricyclenedicarboxylic acid (la) and to the corresponding dimethyl ester (1b) gave adducts [exo-5-chloro-endo-3-phenylthiotricyclo[2.2.1.0^2,6]heptane-2,exo-3-dicarboxylic acid ...
The Esterolytic activity of poly(1-methyl-4- and -5-vinylimidazole) in water
(American Chemical Society: Macromolecules, 1975-07)
The water solubility of poly(1-Me-5-VIm) has made it possible to achieve phenomenal rate enhancements and to gain even greater insight into the mechanism of catalysis by polymeric imidazoles. The poly(l-Me-5-V1m)-catalyzed ...
The Esterolytic activity of poly(N-alkylimidazoles) in ethanol-water. The poly(1-methyl-5-vinylimidazole)-catalyzed hydrolysis of p-nitrophenyl acetate and 3-nitro-4-acetoxybenzoic acid
(American Chemical Society: Macromolecules, 1975-07)
1-Methyl-4-vinylimidazole (1-Me-4-VIm) and 1-methyl-5-vinylimidazole (1-Me-5-VIm) have been synthesized and polymerized. The esterolytic activity of these polymers in 28.5% ethanol-water toward p-nitrophenyl acetate (PNPA) ...
The Esterolytic activity of poly(N-alkylimidazoles). The effect of ester chain length in the substrate and alkyl chain length in the catalyst on the esterolytic activity of poly(N-alkylimidazoles).
(American Chemical Society: Macromolecules, 1975-07)
In an effort to exploit the enhancement in catalytic activity which might be derived through hydrophobic interactions between polymeric catalyst and substrate, 1-methyl-5-vinylimidazole (l-Me-5-VIm), l-methyl-4-vinylimidazole ...
Nonlinear optimization; some applications to colorant formulations
(The Optical Society of America, 1975-06)
The total synthesis and anti-fertility activity of 6-silasteroids
(Elsevier: Tetrahedron, 1975)
4,4-Dimethyl-6-methoxy-4-sila-1-tetralone (2) was prepared by a modified literature procedure and converted to 3-methoxy-6,6-dimethyl-6-silaestra-1,3,5(10),8,14-pentaen-17β-yl acetate (5c). Catalytic hydrogenation of 5c ...
Electrochemical generation of stable arene metal tricarbonyl dianions
(The American Chemical Society, 1975)
A Summary of recent satellite time transfers from the U.S. Naval Observatory to the Royal Greenwich Observatory and to Australia
(The Institute of Electrical and Electronics Engineers (IEEE), 1974-12)
This paper describes the TIMATION II satellite time transfer experiments between the U.S. Naval Observatory (USNO) and the Royal Greenwich Observatory (RGO) in 1972, and between the U.S. and Australia, in 1973. The error ...
A gas chromatographic-mass spectrometric comparison of polychlorinated biphenyl residues in the Japanese quail brain to an Aroclor standard
(Springer-Verlag: Bulletin of Environmental Contamination and Toxicology, 1974-04)
