The phrase "and exit of a" is not correct and usable in written English as it is incomplete and lacks context.
It could potentially be used in a context discussing the process of entering and exiting a location or system, but it needs additional information to be meaningful.
Example: "The procedure includes the entry and exit of a user from the system."
Alternatives: "and departure of a" or "and leaving of a".
We show how competition in oligopolies, with the possibility of failure and exit of a levered incumbent, affects the ex-ante design of optimal debt contracts.
In this paper, we present a novel high-voltage kinetic energy harvesting system that is installed at the entrance and exit of a road tunnel.
The two-dimensional water entry and exit of a body whose shape varies in time in a prescribed way is investigated through analytical and numerical modelling.
In particular, the entrance and exit of a fishway have often been closed due to the action of erosion and deposition resulting from extreme flood events that occur in the monsoon season of Korea.
The tracer concentration distributions, measured at the entrance and exit of a single stage, and the simultaneously measured drop size distribution in the monitored stage were discretized appropriately to provide drop residence times and axial velocities in agitated dispersions.
There are several research gaps according to the descriptions of the previous studies' findings related to the vehicle trajectories: i) as seen in Fig. 1, only the lateral locations at a few cross sections along the road were considered, such as at the entrance, midpoint, and exit of a curve.
Second, the rate constant k f includes implicitly entrance and exit of TF-A protein from the relatively small nuclear volume, thus larger than those governing the dynamics of overall cellular [TF-A].
This is because the rate constants k f and k d include implicitly entrance and exit of TF-A protein from the relatively small nuclear volume and are thus larger than those governing the dynamics of overall cellular concentration of TF-A.
This configuration allows the enzyme to adopt an "open" conformation, that permits the entry of substrates and exit of products, and a "closed" conformation, wherein substrates are completely entrapped within an unusually large internal chamber [23].
The entry and exit of terrorists in a matter of great concern.
Our results show that some regions, responsible for entrance and exit of substrate, present a conformational variability, which is dissected by dynamics simulation analysis.
