Tissue samples from 1,117 fish of 25 species were collected from 1991 through 1996 at 13 locations along the River Elbe. The principal indicator species were perch (Perca fluviatilis) (n=118), chub (Leuciscus cephalus L.) (n=113) and roach (Rutilus rutilus) (n=138). Mercury (Hg) concentrations in muscle and liver were determined by atomic absorption spectrometry. The liver/muscle index in three...

In order to reduce computatiomd ald storage c~sts of learning methods, we present a protot.,~T)e selection algorithm. This apl)roach uses il,formation contained in a connected neighborhood graph. It determines the number of homogeneous subsets in the Rp space, and uses it to fix the number of prototypes in advance. Once this number is determined, we. idcntii~," prototypes applying a stratified ...

Virginia Kiryakova Dedicated to the 75th anniversary of Professor Gary Roach Abstract A generalization of the Poisson-type integral transformation proposed by Dimovski is applied to hyper-Bessel differential equations of arbitrary order, as a transmutation operator. By this method, their solutions are written in an explicit form, by evaluating operators of the generalized fractional calculus of...

INTRODUCTION Oak-dominated forests of the Central and Eastern United States have generally not been regarded as suited to uneven-aged silviculture (Roach and Gingrich 1968, Sander and Clark 1971). In fact, several attempts to apply the selection method of reproduction cutting in oak-dominated stands have resulted in compositional shifts toward more shade tolerant species (Trimble 1970). Given t...

In this article, we analyze the stability, reactivity, and possible aromatic behavior of two recently reported clusters (Reveles, J. U.; Khanna, S. N.; Roach, P. J.; Castleman, A. W., Jr. Proc. Natl. Acad. Sci. 2006, 103, 18405), viz., Al(7)C(-) and Al(7)O(-) in the light of the principles of the maximum hardness and minimum electrophilicity as well as the nucleus-independent chemical shift val...

BACKGROUND Both frequency and intensity of flood events are expected to increase as a result of global climate change in the upcoming decades, potentially resulting in increased re-suspension of sediments in fluvial systems. Contamination of these re-suspended sediments with legacy contaminants, including dioxins and dioxin-like compounds (DLCs), as well as polycyclic aromatic hydrocarbons (PAH...
