Effect of nitrogen application and year on concentration of Cu, Zn, Ni, Cr, Pb and Cd in herbage of Galega orientalis Lam.

Plant, Soil and Environment, 2015
Eastern galega is promising forage species for Central Europe, but little is known about its forage quality in terms of elemental composition. We asked how the concentrations of Cu, Zn, Ni, Cr, Pb and Cd in its herbage are affected by application of ...

Unique Post-telemetry Recapture Enables Development of Multi-Element Isoscapes From Barnacle Shell for Retracing Host Movement

Frontiers in Marine Science, 2020
Many ecological investigations rely on understanding the movement of animals through marine environments. Most available tracking techniques are invasive (e.g., tissue sampling) and require extensive effort and/or cost (e.g., capture-mark-recapture or ...

Isotope shift in the Sulfur electron affinity: observation and theory

, 2010
The electron affinities eA(S) are measured for the two isotopes 32S and 34S (16752.9753(41) and 16752.9776(85) cm-1, respectively). The isotope shift in the electron affinity is found to be positive, eA(34S)-eA(32S) = +0.0023(70) cm-1, but the ...

Carbon isotope fractionation during aerobic biodegradation of trichloroethene by Burkholderia cepacia G4: a tool to map degradation mechanisms [PDF]

, 2002
The strain Burkholderia cepacia G4 aerobically mineralized trichloroethene (TCE) to CO2 over a time period of similar to20 h. Three biodegradation experiments were conducted with different bacterial optical densities at 540 nm (OD(540)s) in order to test

Functionalized Lignin Derivatives as Melt‐Spinnable Precursors for Carbon Fiber Production without Stabilization

Advanced Functional Materials, EarlyView.
By turning off hydrogen bonds by bulky ethyl cinnamate ester derivatization, softwood kraft lignin can flow under elevated temperatures, providing tough fiber in the melt for high take‐up speed. Subsequently, lignin ethyl cinnamate derivatives are readily stabilized with only dilute nitric acid leading to direct carbonized fiber with outstanding ...

Posthumanism, the Transcorporeal and Biomolecular Archaeology

Current Swedish Archaeology, 2013
This paper will discuss the tensions between the humanities and sciences within archaeology and examine how these tensions exist, both in how identity and personhood are understood, and in different views of epistemology and ontology.
