Dielectric-barrier discharge (DBD) is the electrical discharge between two electrodes separated by an insulating dielectric barrier. Originally called silent (inaudible) discharge and also known as ozone production discharge [ 1 ] or partial discharge , [ 2 ] it was first reported by Ernst Werner von Siemens in 1857.
Form factor is a hardware design aspect that defines and prescribes the size, shape, and other physical specifications of components, particularly in electronics. [ 1 ] [ 2 ] A form factor may represent a broad class of similarly sized components, or it may prescribe a specific standard.
In "Step 2" of the setup page, there is a box with a pattern which you have to point your device's camera toward. (Your device might ask you for permission to use the camera first.) If you can't scan the QR code, you can enter the "Two-factor authentication secret key" from "Step 2" of the setup page into the app, which gives you the same result.

The stacking factor (also lamination factor or space factor [1]) is a measure used in electrical transformer design and some other electrical machines. It is the ratio of the effective cross-sectional area of the transformer core to the physical cross-sectional area of the transformer core. The two are different because of the way cores are ...
A 5-year-old girl is clinging to life after police in Washington D.C. say her 3-year-old brother grabbed an unsecured gun from inside the family's home and shot her while playing with it. At least ...
The form is pulled back to the submanifold, where the integral is defined using charts as before. For example, given a path γ(t) : [0, 1] → R 2, integrating a 1-form on the path is simply pulling back the form to a form f(t) dt on [0, 1], and this integral is the integral of the function f(t) on the interval.
Biden again said he believed he could have beaten Trump in a rematch. The president announced that he was leaving the race following his shaky debate performance against him in June that laid bare ...
