Metallic iron for environmental remediation: learning from the Becher process.
Metallic iron (Fe(0)) is a moderately reducing agent that has been reported to be capable of reducing many environmental contaminants. Reduction by Fe(0) used for environmental remediation is a well-known process to organic ...
DisKon - Disposition und Konfliktlösungsmanagement für die beste Bahn
(Techn. Univ., Fak. Verkehrswiss. Friedrich List, 2005)
Within the framework of a research cooperation we currently develop a laboratory version of a flexible, modular, and automatic dispatching system. The algorithms of this system shall support the recognition and solution ...
Locating a minisum circle in the plane
We consider the problem of locating a circle with respect to existing facilities in the plane such that the sum of weighted distances between the circle and the facilities is minimized, i.e., we approximate a set of given ...
A critical review on the process of contaminant removal in Fe0-H2O systems.
A central aspect of the contaminant removal by elemental iron materials (Fe0 or Fe0 materials) is that reduction reactions are mediated by the iron surface (direct reduction). This premise was introduced by the pioneers ...
Lifetime and fluorescence quantum yield of uranium(VI) species in hydrolyzed solutions
Fluorescence lifetimes and emission intensities of uranium(VI) species UO22+, (UO2)2(OH)22+ and (UO2)3O(OH)3+ (=(UO2)3(OH)5+) are determined after excitation by a dye laser at 420 nm. Despite the widely varying species ...
Relevant Reducing Agents in Remediation Fe0/H2O systems
Metallic iron (Fe0) is often reported as a reducing agent for environmental remediation. There is still controversy as to whether Fe0 plays any significant direct role in the process of contaminant reductive transformation. ...
Combination of searches for anomalous top quark couplings with 5.4 fb−1 of pp collisions
We present measurements of the tWb coupling form factors using information from electroweak single top quark production and from the helicity of W bosons from top quark decays in t¯t events. We set upper limits on anomalous ...
Cytoplasmic polyadenylation element binding protein (CPEB)1 and 2 bind to the HIF-1α mRNA 3’UTR and modulate HIF-1 α protein expression
(Portland Press Limited, 2010)
The heterodimeric hypoxia-inducible factor (HIF)-1 is a transcriptional master regulator of several genes involved in mammalian oxygen homeostasis. Besides a well described regulation of the HIFα-subunit via hydroxylation-mediated ...
The path player game
We introduce the path player game, a noncooperative network game with a continuum of mutually dependent set of strategies. This game models network flows from the point of view of competing network oper- ators. The ...
Geographic bias of field observations of soil carbon stocks with tropical land-use changes precludes spatial extrapolation
Accurately quantifying changes in soil carbon (C) stocks with land-use change is important for estimating the anthropogenic fluxes of greenhouse gases to the atmosphere and for implementing policies such as REDD (Reducing ...
