The tip of the instrument is placed with light pressure of 10-20 grams [1] into the gingival sulcus, which is an area of potential space between a tooth and the surrounding tissue. It is important to keep the periodontal probe parallel to the contours of the root of the tooth and to insert the probe down to the base of the pocket. This results ...
The Williams diagram is universal in the sense that it is applicable to both premixed and non-premixed combustion. In supersonic combustion and detonations , the diagram becomes three-dimensional due to the addition of the Mach number M a = u ′ / c {\displaystyle Ma=u'/c} as the z-axis, where c {\displaystyle c} is the sound speed .
A probe tip is an instrument used in scanning probe microscopes (SPMs) to scan the surface of a sample and make nano-scale images of surfaces and structures. The probe tip is mounted on the end of a cantilever and can be as sharp as a single atom .
These settings are normally available as templates in chemical drawing programs. Use sans-serif fonts like Arial. Indexes used for labelling must be superscripted: R 1-CH 2-R 2 (not R 1-CH 2-R 2) Do not include English text in images: this prevents their reuse in other languages.
A probe card or DUT board is a printed circuit board (PCB), and is the interface between the integrated circuit and a test head, which in turn attaches to automatic test equipment (ATE) (or "tester"). [2] Typically, the probe card is mechanically docked to a Wafer testing prober and electrically connected to the ATE . Its purpose is to provide ...
Drawing of a Thiele tube with red arrows showing convection current A photograph of a Thiele tube. The oil level is a little low now to compensate for expansion when heating commences. The Thiele tube, named after the German chemist Johannes Thiele, is a laboratory glassware designed to contain and heat an oil bath.
A passive oscilloscope probe with a switch in the probe handle that selects 1× or 10× attenuation. To minimize loading, attenuator probes (e.g., 10× probes) are used. A typical probe uses a 9 megohm series resistor shunted by a low-value capacitor to make an RC compensated divider with the cable capacitance and scope input.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible. To change this template's initial visibility, the |state= parameter may be used:
