[12] [13] It is a light adapted test that allows one to measure plant stress while the plant is undergoing the photosynthetic process at steady-state photosynthesis lighting conditions. Like FvFm, Y(II) represents a measurement ratio of plant efficiency, but in this case, it is an indication of the amount of energy used in photochemistry by ...
The two rows of holes (labelled #3) are test points used during the manufacture of this USB memory key. Testpoints on a printed circuit board (labelled E34, E35, E36, …) next to teardrop vias. A test point is a location within an electronic circuit that is used to monitor the state of the circuitry or inject test signals. [1]
VFR / VMC visibility requirements in the US. In aviation, visual meteorological conditions (VMC) is an aviation flight category in which visual flight rules (VFR) flight is permitted—that is, conditions in which pilots have sufficient visibility to fly the aircraft maintaining visual separation from terrain and other aircraft.
A laboratory rat with a brain implant, that was used to record in vivo neuronal activity. Studies that are in vivo (Latin for "within the living"; often not italicized in English [1] [2] [3]) are those in which the effects of various biological entities are tested on whole, living organisms or cells, usually animals, including humans, and plants, as opposed to a tissue extract or dead organism.
Vivo Mobile Communication Co., Ltd., d/b/a vivo, is a Chinese multinational technology company headquartered in Dongguan, Guangdong, that designs and develops smartphones, smartphone accessories, software, and online services.
Most test pilot schools use multiple, more specific minimum control speeds, as V MC will change depending on the stage of flight. Other defined V MC s include minimum control speed on the ground (V MCG ) and minimum control speed during approach and landing (V MCL ).
The four-point flexural test provides values for the modulus of elasticity in bending, flexural stress, flexural strain and the flexural stress-strain response of the material. This test is very similar to the three-point bending flexural test. The major difference being that with the addition of a fourth bearing the portion of the beam between ...
A common form of in-circuit testing uses a bed-of-nails tester.This is a fixture that uses an array of spring-loaded pins known as "pogo pins". When a printed circuit board is aligned with and pressed down onto the bed-of-nails tester, the pins make electrical contact with locations on the circuit board, allowing them to be used as test points for in-circuit testing.
