Novgorod city has retained a handsomeness and a concentration of monuments denied most other regional capitals a factor by no means negligible in its appeal to investors.
Young, and barely oxidized in the processing, the leaves retain a high concentration of anti-oxidants: in the last 10 years, a string of research papers has asserted that white tea may have health benefits in helping to reduce cancer and heart disease risks, and fighting the effects of aging.
The half-life of 239Np is far too short for it to be produced as fast as it decays and retain a constant concentration, despite it continuously being produced, although the detection of its much longer-lived daughter 239Pu in nature in 1951 definitively established its natural occurrence.
Finally, the fact that cells may accumulate and retain a higher concentration of NB7M (because it is more lipophilic than 7Me-IEITC) might explain the differences in drug cytotoxicity.
Based on these observations it was postulated that Lob 1 found in the breast of nulliparous women and of parous women with breast cancer never went through the process of differentiation, retaining a high concentration of epithelial cells that are targets for carcinogens and are therefore susceptible to undergo neoplastic transformation.
Nanoparticles prepared with the highest concentration chitosan retained a positive zeta potential after dispersion in simulated lachrymal fluid, which supports the possibility of an electrostatic interaction between these particles and the negatively charged mucus layer at the eye.
The residual liquid retains a correspondingly enhanced concentration of heavy water.
We investigate here numerically the influence of VF between the carrier fluid and the sample solvent on the spreading of a retained analyte concentration peak in a three-component system (displacing fluid, sample solvent, analyte).
The solution shows that for small retained concentrations, the suspended concentration is in a steady-state behind the concentration front, where all the retained concentrations are proportional to the mass of suspended particles that passed via a given reservoir cross-section.
Therefore, for quantification purposes where the arterial input concentrations of contrast must reliably be defined, one should use much lower doses of gadolinium, i.e., in the order of 0.005 0.03 mmol kg−1, to retain a linear relation between contrast concentration and the obtained signal.
