Spot analysis, spot test analysis, or spot test is a chemical test, a simple and efficient technique where analytic assays are executed in only one, or a few drops, of a chemical solution, preferably in a great piece of filter paper, without using any sophisticated instrumentation. The development and popularization of the test is credited to ...
Open-Sankoré is the first feature-complete open-source interactive whiteboard. In contrast to other similar software, its file format is text-based and uses a W3C web standard, allowing to be displayed in a modern web browser and enabling lessons to be distributed online without additional software. Second, the software can be extended using ...
An interactive whiteboard ( IWB ), also known as interactive board, interactive display, interactive digital board or smart board, is a large interactive display board in the form factor of a whiteboard. It can either be a standalone touchscreen computer used independently to perform tasks and operations, or a connectable apparatus used as a ...

2D-Gels (Coomassie stained) Robots are used for the isolation of protein spots from 2D gels in modern laboratories. Two-dimensional gel electrophoresis, abbreviated as 2-DE or 2-D electrophoresis, is a form of gel electrophoresis commonly used to analyze proteins. Mixtures of proteins are separated by two properties in two dimensions on 2D gels ...
Low-energy electron diffraction ( LEED) is a technique for the determination of the surface structure of single-crystalline materials by bombardment with a collimated beam of low-energy electrons (30–200 eV) [ 1] and observation of diffracted electrons as spots on a fluorescent screen.
Notes Vertigo: 1958 To create the spirals seen in the opening credit sequence of his film, Alfred Hitchcock hired John Whitney, who used a WWII anti-aircraft targeting computer called "The M5 gun director" mounted on a rotating platform with a pendulum hanging above it that it tracked. Its scope was filmed to create the various spiral elements ...
Notation for calculating the wave amplitude at point P 1 from a spherical point source at P 0.. At the heart of Fresnel's wave theory is the Huygens–Fresnel principle, which states that every unobstructed point of a wavefront becomes the source of a secondary spherical wavelet and that the amplitude of the optical field E at a point on the screen is given by the superposition of all those ...
