English term

in a day

English Science sampling freq�ency
Hello, ProZ.

I have this sentence and I'm not sure about the correct use of the article (definite or indefinite):

Collections were done at every 4 hours, and on each day the collection time was delayed by 1 hour; therefore, by the end of the fourth day one collection had been taken at each one of the 24 hours ***in the day***.

in the day?
in a day?
of a day?

meaning, in the 4-day period, there was at least one sample available for each of the 24 hours there are in a day.

TIA

per day

There are several issues with the sentence. Try this:

Collections were made every 4 hours. The collection time was delayed by 1 hour each day; therefore, by the end of the fourth day, one collection was made every 24 hours, i.e., one collection per day.

Since I do not know what kind of collection we are referring to, I am reluctant to suggest a specific verb to use, but, prima facie, I would not use "do." I would suggest "make" or "take," depending on the kind of collection, and I would suggest using the same verb for consistency.

David\'s comment has just given me the right kick in the right spot to wake up. Here is my revised wording:

Collections were made every 4 hours. The collection time was delayed by 1 hour each day; therefore, by the end of the fourth day, one collection was made each hour of the 24 hours in a day.

I am not committing to any preposition before the word \"hour\" in the last phrase, because I do not know if they mean every hour on the hour or just every hour. If the former, you can use \"at;\" if the latter, you can use \"in\" or \"within,\" but I would just as well leave it without a preposition.

Thank you, David.
Peer comment(s):

disagree David Sirett : No. at the end of the fourth day collections were still being made every 4 hours, but at later times.

at each of the 24 hours of a day

a day has 24 hours.

but I would put it differently:
by the end of Day 4, data had been sampled on each hour of a 24-day period.

in each 24-hour period

Hello Henrique
I would change the phrase as above. It is, I think, widely recognised that "24-hour period" is a more precise way of refering to a "day" as it is construed in your context, in which the word "day" is too colloquial imo.
Best regards
Derek

a rewording

To assure that one collection was taken during each of the 24 hours of a day, a 4-day collection cycle was designed whereby collections were taken at 4-hour intervals staggered by one hour at each of the 4 collection days.

My rewording

Collections were done at every 4 hours, and on each day the collection time was delayed by 1 hour; therefore, by the end of the fourth day one collections had been taken at all hours in a day.

5 hrs

once every 24 hours

Collections were done every 4 hours and each day, the collection time was delayed by one hour; consequently, by the time 4 days had passed, sampling was being done once every 24 hours.
Explanation:
If collections are being done every 4 hours, that means 6 collections are being done per day. If those 6 collections are delayed by 1 hour each time a collection is taken, the collections will be taken 6 hours later every day. By the time 4 days roll around, at the pace of 6 hours delay per day, samples are only being taken once every 24 hours! (6x4=24)
This is what I can gather from the info provided, however, it would be much better to have the original text in order to be sure that the translation is indeed correct. I really think you need to confirm the translation before you worry about the prepositions, although I agree with Fuad that there are other serious problems with prepositions in this passage - especially 'collections were done AT every 4 hours.' (incorrect)
