Flat and faulty cells will have high ESRs. A dry cell's ESR increases as it is used, going high when flat. A rechargeable cell or pack can be measured while on charge or load, provided the current is steady. Even the tiniest button cells may be checked, as there is no load current...

The result shows: applied with stirring, the electromagnetic force generates and it increases with the frequency; In condition of applied stirring parameters with current 100A and frequency 5hz, the maximum of magnetic induction is 0.026T, and the maximum of current density is 33537A/m2; the ...
The heterogeneous nuclear ribonucleoprotein M (hnRNPM) promotes epithelial-mesenchymal transition (EMT) and metastasis in breast cancer by promoting the biased expression of CD44 standard isoform (CD44s) [7]. Similarly, hnRNP A2 increases breast cancer cell invasion by promoting the expression of a ...
NITRIDING Nitriding increases the surface hardness and wear resistance. For best result the following steps should be followed: 1. Rough machining 2. Temper at a temperature between 480 - 525oC thus reducing the amount of stresses and retained austenite content. This will minimise later dimensional...

in ESR the consumable electrode is dipped into a pool of slag in a water-cooled mold. An electric current (usually AC) passes through the slag, between the electrode and the ingot being formed and superheats the slag so that drops of metal are melted from the electrode. They travel throug...
This grounding and layout scheme minimizes inductive parasitics, and thereby reduces load-current transients, minimizes noise, and increases circuit stability. TI also recommends a ground reference plane, either embedded in the PCB itself or located on the bottom side of the PCB opposite the ...
According to the formula for the Bohr energy levels the energy increases in the state n with increasing mass: En = E 0 n 1 − m M (3) where m: mass of the electron; M: mass of the nucleus Particularly for spectra of systems resembling that of hydrogen,...
This increases the demand on short pulse duration, as for coincidence measurements single-particle counting needs to be maintained with very high efficiency throughout the course of a beamtime campaign. We use a channel electron multiplier (CEM) with extended dynamic range, which is able to ...
