The phrase "a certain mobility" is correct and usable in written English.
It can be used to describe a specific type or degree of mobility in various contexts, such as physical movement, social mobility, or economic mobility.
Example: "The new policy aims to promote a certain mobility among employees, allowing them to move freely between departments."
Alternatives: "a specific mobility" or "a particular mobility".
Conductometric titration is an analytical technique based on the mobility difference, that is, ions of a certain mobility are replaced by other ions that possess a different mobility.
This means, that for the duration of a transmission burst, the channel remains constant in time unless a certain mobility is indicated.
Section 3 addresses a user movement scenario and its impact on the key parameters of Wireless Information-Theoretic Security, for a certain mobility model.
(6) G (n ) = b (n + 1 ) - b (n ) ; n = [ 1, …, H - 1 ] A common application of gel analysis includes genotyping in which bands of a certain mobility are associated with common DNA fragments.
As shown in Scheme 1, the SO molecules immobilized in the outer layers are suggested to be in contact with the electrode via the cyt c network, and the adsorbed proteins thus maintain a certain mobility which allows intermolecular protein interactions.
Considering the exponential growth of smartphone ownership [50], this later approach in particular can widely be used to capture certain mobility characteristics such as average speed and distance travelled, functioning in a similar manner to pedometers in persons who do not use wheelchairs.
However, most of them only work for certain mobility patterns.
We also will most likely see brands and companies focusing on certain mobility niches.
It should also be underlined that currently, mobility is characterised by a certain unpredictability because mobility practices change rapidly.
The advantages of this design are the relatively high duty cycle because of the trap SRIG and the quadrupole analyser before the ion mobility cell, and the possibility to enhance the detection of certain mobility-separated ions by synchronizing the pusher of the TOF and the release of the ions by the transfer cell.
