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 ...
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 ...
Dlk1 promotes a fast motor neuron biophysical signature required for peak force execution.
Motor neurons, which relay neural commands to drive skeletal muscle movements, encompass types ranging from "slow" to "fast," whose biophysical properties govern the timing, gradation, and amplitude of muscle force. Here ...
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 ...
Allergic aspergillosis and the antigens of Aspergillus fumigatus
Incidence of fungal infections has increased alarmingly in past few decades. Of the fungal pathogens, the Aspergillus fumigatus has been a major cause of allergic bronchopulmonary aspergillosis (ABPA) which has five main ...
Genetic ablation of VIAAT in glycinergic neurons causes a severe respiratory phenotype and perinatal death
Both glycinergic and GABAergic neurons require the vesicular inhibitory amino acid transporter (VIAAT) for synaptic vesicle filling. Presynaptic GABA concentrations are determined by the GABA synthesizing enzymes glutamate ...
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 ...
