Learn English – The preposition with the word “settings”

A phrase using the verb "to ban" with a subject and a location typically follows the form "To ban subject from [(verb)ing at] location"

ILLOGICAL: There’s no necessity to ban prepositions from using (them) at the end of sentences.

When you ban something from (verb)ing at location, you prohibit the subject from performing the action at the specified place. Here you are prohibiting the prepositions themselves from using (something unspecified: them) at the location the end of the sentence. The issue here is less the structure of the sentence than the choice of verb: 'using' appears to have no object, and it seems unlikely that a preposition would be able to 'use' (take illegal drugs) in a colloquial sense.

CORRECT: There’s no necessity to ban prepositions from being at the end of sentences.

Here, prepositions are prohibited from performing the action, being, when at the end of sentences. They are not allowed to exist at the end of sentences. This is quite clear.

ALSO CORRECT: There’s no necessity to ban prepositions from the end of sentences.

When banning someone/something, the "verb + at" is optional. If excluded, as in "To ban subject from location, "being in" or "being at" is implicitly understood. This example has the same meaning as the previous example and is also very clearly phrased.

Both correct examples are fairly standard and including "being at" shouldn't sound particularly strange to a native ear. Since language tends towards simplicity, however, the exclusion of the verb is more likely.

Both "on" and "over" are acceptable prepositions to use with "influence"; however in this context of a scientific experiment, "on" is probably the more idiomatic choice. In most contexts, "on" implies a variable or unknown degree of influence. Example:

This study measured the influence of small concentrations of various environmental contaminants on the mating habits of Columba livia domestica (the common domestic pigeon)

"Over" implies a greater degree of influence, or influence over a wider range. For example:

The senators have repeatedly questioned whether the President has had an undue influence over the investigation.

Here we could use "on", but it would change the meaning, as the writer wants to say that the senators implied the President did improperly influence the investigation.
