Trichlorofluoroethene (TCFE) was used as a reactive tracer to determine the in situ rate of reductive dechlorination in treatment zones impacted by three large-diameter permeable columns (LDPCs) that were installed at a trichloroethene (TCE)–contaminated site. The LDPCs were part of a pilot study to evaluate the effectiveness of hydrogen, lactate, and zerovalent iron for remediating TCE-contami...

The distribution of size fractionated dissolved iron (DFe, <0.2 mum) species was determined in the upper water column (0-150 m) of the Canary Basin (25-32 degrees N and 18-24 degrees W) on a research cruise in October 2002. A DFe concentration gradient resulting from a decrease in both soluble iron (SFe, <0.02 microm) and colloidal iron (CFe, 0.02-0.2 microm) was shown to extend from the coast ...

PURPOSE In the epidermis, proliferative basal cells can be divided into two subpopulations according to their response to phorbol ester tumor promoters. The tumor promoter-sensitive subpopulation ceases mitosis and initiates terminal differentiation and, thus, represents more differentiated transient amplifying cells. In contrast, the tumor promoter-resistant subpopulation that continues to pro...

The efficacy of cell-free gene expression (CFE) has been considerably improved in the last decade. As a consequence, CFE systems have now capacity to express DNAs composed tens genes encoding for complex self-assembly processes. A recent example is demonstration that infectious bacteriophages can be synthesized one-pot reactions from their genomes. This landmark result opens new perspectives pr...

A field trial was conducted twice (in 2020 and 2021) to evaluate the effect of clove fruit extract (CFE) and/or salicylic acid (SA), which were used as a foliar nourishment, on growth yield traits, well physiological biochemical indices utilizing potato (Solanum tuberosum L.) plants irrigated with deficient regimes in an arid environment. Three drip irrigation [e.g., watering (7400 m3 ha?1), mo...

Dear Editor, This letter proposes a process-monitoring method based on temporal feature agglomeration and enhancement, in which novel extractor called contrastive (CFE) extracts the relational features among process parameters. Then representations are enhanced by maximizing separation different classes while minimizing scatter within each class.

Fast Scan Cyclic Voltammetry (FSCV) relies on detection of amperometric changes resulting from specific oxidation and reduction events during rapid voltage cycling on an implanted carbon fiber electrode (CFE). Previous systems have documented FSCV recording for detection of dopamine[1], norpeinepherine[2] and serotonin[3] using both tethered[1] & wireless[2,4,5] recording devices. We have devel...

Poly(vinylidene fluoride-trifluoroethylene-chlorofluoroethylene), P(VDF-TrFE-CFE), samples were prepared by solvent casting varying polymer concentration and evaporation temperature. Different sample morphologies obtained depending on the processing conditions, as well different physical-chemical properties such degree of crystallinity, mechanical dielectric properties. On other hand, electroac...

For fractional-order differentiator where is a real number, its discretization is a key step in digital implementation. Two discretization methods are presented. The first scheme is a direct recursive discretization of the Tustin operator. The second one is a direct discretization method using the Al-Alaoui operator via continued fraction expansion (CFE). The approximate discretization is minim...
