Excitation and emission fluorescence spectra of 2-naphthol and 2-methoxynaphthalene were measured in a series of pure solvents. The spectral shifts are correlated by the Kamlet-Taft parameters (π*, â, and R). As judged from the π* dependence, both molecules have a negligibly small dipole moment in their ground electronic state, which increases in the excited (S1) state. However, the majority of...

This paper uses a unique data set of monthly new vehicle sales by detailed model from 19702007, and implements a new identification strategy to estimate the effect of gasoline prices on new vehicle demand. We control for unobserved vehicle and consumer characteristics by using within model-year changes in gasoline prices and vehicle sales. We find a significant demand response, as nearly half o...

Examined fish of the genus Baryancistrus (Loricaridae) from Rio Xingu in central amazonian Brazil were found infected with extrasporogonic stages of Sphaerospora sp. (Myxosporea) in the blood and sporogonic stages in the glomeruli with the resulting escape of the sporogony products into the renal tubules, apparently when the mesangial tissue in the Bowman's capsule collapsed. Spores were seen e...

We give the classification of quiver Hopf algebras with pointed module structures. This leads to the classification of multiple crown algebras and multiple Taft algebras as well as pointed Yetter-Drinfeld modules and their corresponding Nichols algebras. In particular, we give the classification of graded Hopf algebras on cotensor coalgebra T c kG(M) of kG-bicomdule M over finite commutative gr...

PARTICULARLY since the advent of cardiac catheterization, primary pulmonary hypertension has been of increasing interest to clinicians and pathologists alike. To some it represents a pulmonary vasospastic disease, presumably of neurohumoral type, analogous to systemic essential hypertension. The occasional association of primary pulmonary hypertension with Raynaud's disease is thought to suppor...
