A kinetic investigation on the hydrolysis of simple aliphatic dicarboxylic tertiary butyl esters: Part I
Autor: J. D. H. Homan
Publikováno v: Recueil des Travaux Chimiques des Pays-Bas. 63:181-188
The ratio k1/k2 of the alkaline saponification coefficients for the methyl and ethyl esters of the symmetrical aliphatic dicarboxylic acids, seems to be controled only by a statistical factor 2 and by the effect of the ionic centre in the mono-ester

Autor: Susan E. White, Alan D. Bocking, Jacobus H. Homan, Karen A. Kimura, Laurence J. Fraher, Carole S. Watson, John R. G. Challis, James F. Brien
Publikováno v: Journal of Applied Physiology. 86:1410-1420
Adenosine and PGE2are neuromodulators, both of which inhibit fetal breathing movements (FBM). Although circulating PGE2has been implicated as a mediator of ethanol-induced inhibition of FBM in the late-gestation ovine fetus, a role for adenosine has

Determining Costs in VA
Autor: T J Menke, T M Kashner, R H Homan
Publikováno v: Medical Care. 37:AS18-AS26
Background Department of Veterans Affairs (VA) administrative cost data bases contain inaccuracies and do not provide patient-level data. Objective To describe methods of VA cost determination that are appropriate for specific types of studies and to

Similarity in physical organic chemistry: Substituent effects on the intrinsic basicity of 4-substituted pyrazoles
Autor: José-Luis M. Abboud, Rafael Notario, Isabelle Forfar, H. Homan, A. El Hammadi, M. Herreros, J. Elguero, Rosa M. Claramunt
Publikováno v: Journal of Physical Organic Chemistry. 7:657-662
The gas-phase basicities of eight pyrazoles substituted only at position 4 (R4 = H, NO2, F, Cl, CO2C2H5, CH3, NH2, 1-adamantyl) were measured by Fourier transform ion cyclotron resonance. The experimental values were treated in two ways, first by com

Basicity of C-substituted pyrazoles in the gas phase: an experimental (ICR) and theoretical study
Autor: H. Homan, J. L. G. De Paz, J. Elguero, José-Luis M. Abboud, Rafael Notario, T. Canada, Rosa M. Claramunt, Pilar Cabildo, Javier Catalán
Publikováno v: The Journal of Organic Chemistry. 57:3938-3946
The experimental gas-phase proton affinities (PAs) of 32 N-H and N-methyl pyrazoles have been determined by means of Fourier transform ion cyclotron resonance spectrosccopy (FTICR). Together with the previously reported PAs for 12 C-methyl-substitute

The gas-phase proton affinities of selected 0-lactams, amides, cyclic and acyclic ketones, azetidine, and acyclic amines were measured by FTICRMS techniques. SCF and MP2 calculations at different levels of accuracy have been performed for the differe
