A photocathode is a negatively charged electrode in a light detection device such as a photomultiplier or phototube that is coated with a photosensitive compound.

phototube and light
For example, an increase in frequency results in an increase in the maximum kinetic energy calculated for an electron upon liberation – ultraviolet radiation would require a higher applied stopping potential to stop current in a phototube than blue light.

phototube and .

cell and is
A randomization of `` ups '' and `` downs '' is more likely than ordered `` ups '' and `` downs '' in position ( 3 ) since the hydrogen atoms are well separated and so the position of one could hardly affect the position of another, and also since ordered `` up '' and `` down '' implies a larger unit cell, for which no evidence exists.
The last column shows the rate of exchange that would have been observed at a relative intensity of 4 ( 14.7 cm. distance ) calculated on the assumptions that the incident light intensity is inversely proportional to the square of the distance of the lamp from the cell and that the rate is directly proportional to the incident light intensity.

The first is compiling a list of text forms, assigning an information cell to each, and replacing text occurrences with the information cell assigned to the form of each occurrence.
When an occurrence Af is isolated during text reading, a random memory address Af, the address of a cell in the X-region, is computed from the form of Af.
If cell Af has not previously been assigned as the information cell of a form in the text-form list, it is now assigned as the information cell of Af.
The form itself is stored in the next available cells of the W-region, beginning in cell Af.
the information cell Af is saved to represent the text occurrence.
If Af was assigned as the information cell for Af, the routine can detect that Af is identical to Af by comparing Af with the form stored at location Af.
The address Af is stored in the cell Af.
If Af leads to an address Af that is equal to the address computed from Af, even though Af does not match Af, the chain of information cells is extended from Af by storing the address of the next available cell in the Y-region, Af, in Af.
The cell Af becomes the second information cell in the chain and is assigned as the information cell of Af.
Each information cell in the chain contains the address of the Y-cell where the form to which it is assigned is stored.
Each cell except the last in the chain also contains the address of the Y-cell that is the next element of the chain ; ;
Hence, when the address Af is computed from Af, the cell Af and all Y-cells in its chain must be inspected to determine whether Af is already in the form list or whether it should be added to the form list and the chain.

cell and type

The flow of electrons is always from anode to cathode outside of the cell or device, regardless of the cell or device type and operating mode, with the exception of diodes, where electrode naming always assumes current in the forward direction ( that of the arrow symbol ), i. e., electrons flow in the opposite direction, even when the diode reverse-conducts either by accident ( breakdown of a normal diode ) or by design ( breakdown of a Zener diode, photo-current of a photodiode or solar cell ).
In some types of cells ( type I ), processed caspase-8 directly activates other members of the caspase family, and triggers the execution of apoptosis of the cell.
