The cubic metre (symbol m³) is the SI derived unit of volume. It is the volume of a cube with edges one metre in length. Older equivalents were the stere and the kilolitre.Metric conversions and moreConvertUnits.com provides an online conversion calculator for all types of measurement ...
and the like. In some embodiments, the lid12may be configured to automatically reorder replacement liquids in response to determining that the distance20during a measurement exceeds a threshold or that an amount of liquid falls under a threshold. In some embodiments, the threshold may be determined...
(kt2−Q, product of the electromechanical coupling and resonator Q) with respect to conventional sensors and results in an unchanged kt2(approximately 0.8%) with respect to the measurement in air and a Q in fluid of approximately 170. Furthermore, the novel layout permits the delivery of ...

The absorbance of the mixture was determined using a spectrophotometer (Thermo Scientific, Genesys 10S UV-VIS) at a wavelength of 510 nm, and the results were expressed in quercetin equivalents (QE) per gram of dry leaves. For the standard curve, concentrations of 50, 100, 200, 400, 600 ...
To address the question of relative reactivity of the NXS reagent versus recycling and reuse, bromofunctionalization of 1 with 2.2 equivalents of NBS was examined (Table 3) over 5 repeated cycles, showing a gradual decrease in the dibromo derivative 3b with concomitant increase in monobromo ...
