F1 in Schools is an international STEM (science, technology, engineering, mathematics) competition for secondary school students (aged 11–19), in which groups of 3–6 students have to design and manufacture a miniature F1 car using CAD/CAM and CAE design tools.
The peak plasma time is achieved at about 2 hours. [13] Methylphenidate has a low plasma protein binding of 10–33% and a volume of distribution of 2.65 L/kg. [10] Dextromethylphenidate is much more bioavailable than levomethylphenidate when administered orally, and is primarily responsible for the psychoactivity of racemic methylphenidate. [13]
Reaction wheels are used to control the attitude of a satellite without the use of thrusters, which reduces the mass fraction needed for fuel.. They work by equipping the spacecraft with an electric motor attached to a flywheel, which, when its rotation speed is changed, causes the spacecraft to begin to counter-rotate proportionately through conservation of angular momentum.

The first test is read 48–72 hours after injection. If the first test is positive, consider the person infected. If the first test is negative, give a second test one to three weeks after the first injection. The second test is read 48–72 hours after injection. If the second test is positive, consider the person infected in the distant past ...
Interior of a Stevenson screen. The interior size of the screen will depend on the number of instruments that are to be used. A single screen may measure 76.5 by 61 by 59.3 cm (30.1 by 24.0 by 23.3 in) and a double screen 76.5 by 105 by 59.3 cm (30.1 by 41.3 by 23.3 in). The unit is either supported by four metal or wooden legs or a wooden post.
Figure 1 from Experiment 2 of the original description of the Stroop Effect (1935). 1 is the time that it takes to name the color of the dots while 2 is the time that it takes to say the color when there is a conflict with the written word.
The viewfinder is removable (interchangeable with four other viewfinders); The focusing screen can be changed out with 4 (later 9) types; the mirror can be locked up to allow deep seated lenses or for high magnification work, the back is interchangeable with a data and bulk film back (250 exposures), The bottom plate is removable and there are ...
Salkowski's test, [1] also known simply as Salkowski test, is a qualitative chemical test, that is used in chemistry and biochemistry for detecting a presence of cholesterol and other sterols.
