Estrogenic Endocrine Disruption in Switzerland: Assessment of Fish Exposure and Effects
CHIMIA, 2008 Estrogenic exposure has been reported to occur in Swiss rivers, and there is concern that reduced reproductive health, caused by disturbances of the endocrine system, may contribute to the observed decline in brown trout catch.

Asymptotic Spectral Measures: Between Quantum Theory and E-theory [PDF]
arXiv, 2003 We review the relationship between positive operator-valued measures (POVMs) in quantum measurement theory and asymptotic morphisms in the C*-algebra E-theory of Connes and Higson. The theory of asymptotic spectral measures, as introduced by Martinez and Trout (CMP 226), is integrally related to positive asymptotic morphisms on locally compact spaces ...

Building a new environmentalism: News media access and framing in Canada's environmental movement
Canadian Review of Sociology/Revue canadienne de sociologie, EarlyView.Abstract This study provides a content and frame analysis of the news media advocacy of prominent environmental non‐governmental organizations (ENGOs) in Canada. We find that these organizations have an important voice in shaping how climate change is framed in news media, but that ecological modernization frames and narratives, which avoid issues of ...

Errors in Length-weight Parameters at FishBase.org [PDF]
arXiv, 2011 To investigate possible errors, length-weight parameters from FishBase.org were used to graph length-weight curves for six different species: channel catfish, black crappie, largemouth bass, rainbow trout, flathead catfish, and lake trout along with the standard weight curves (Anderson and Neumann 1996, Bister et al. 2000). Parameters noted as doubtful

Curator: The Museum Journal, EarlyView.ABSTRACT Dioramas are an iconic part of natural history museums that present complex scientific content in a naturalistic scenic setting. Museums have struggled with how best to help visitors view and engage in learning at these exhibits. Recognizing the importance of human facilitation around these exhibits, we conducted a study to explore ...

Asymptotic Morphisms and Elliptic Operators over C*-algebras [PDF]
K-theory, 18 (1999) 277-315, 1999 This paper provides an E-theoretic proof of an exact form, due to E. Troitsky, of the Mischenko-Fomenko Index Theorem for elliptic pseudodifferential operators over a unital C*-algebra. The main ingredients in the proof are the use of asymptotic morphisms of Connes and Higson, vector bundle modification, a Baum-Douglas-type group, and a KK-argument of ...

Knowledge and Management of Aquatic Ecosystems, 2017 Quantifying patterns of prey resource use is fundamental to identify mechanisms enabling the coexistence of related fish species. Trophic interactions between the native brown trout, Salmo trutta, and the introduced brook trout, Salvelinus fontinalis ...

On Graded K-theory, Elliptic Operators and the Functional Calculus [PDF]
Illinois Journal of Mathematics, 44 No. 2 (Summer 2000) 294-309, 1999 Let $A$ be a graded C*-algebra. We characterize Kasparov's K-theory group $\hat{K}_0(A)$ in terms of graded *-homomorphisms by proving a general converse to the functional calculus theorem for self-adjoint regular operators on graded Hilbert modules. An application to the index theory of elliptic differential operators on smooth closed manifolds and ...

A Method to Extract Potentials from the Temperature Dependence of Langmuir Constants for Clathrate-Hydrates [PDF]
, 2000 It is shown that the temperature dependence of Langmuir constants contains all the information needed to determine spherically averaged intermolecular potentials. An analytical ``inversion'' method based on the standard statistical model of van der Waals and Platteeuw is presented which extracts cell potentials directly from experimental data.
