Etymology of wheldone

What is the etymology of wheldone? The references doi:10.1021/acs.orglett.0c00219 and doi:10.1021/acs.jnatprod.4c00649 only described the chemical as a fungal metabolite isolated from the coculture of Aspergillus fischeri and Xylaria flabelliformis. --Leiem (talk) 09:00, 25 September 2024 (UTC)[reply]

The clue is in the acknowledgments section of the first paper: "This Letter is dedicated to the late Daniel (Dan) Clive Wheldon". And since Wikipedia has everything: Dan Wheldon. --Wrongfilter (talk) 09:57, 25 September 2024 (UTC)[reply]

I understand. Thank you! --Leiem (talk) 15:38, 25 September 2024 (UTC)[reply]

One might even say...well done. :P SnowRise ^{let's rap} 22:39, 25 September 2024 (UTC) [reply]

Botanical nuts

I'm trying to split Nut (fruit) back into separate articles for food and fruit (because currently a lot of the article content is about things that aren't botanical nuts), but there's not much left after you strip out the food content. Are there any botanists in the house who can recommend sources on botanical nuts and/or weigh in on what should be covered and isn't? AlmostReadytoFly (talk) 10:10, 25 September 2024 (UTC)[reply]

Not a botanist, but I think there's a bit of a problem for having a botanical nut. It is an even fuzzier idea than that of tree. But there's an article on trees so I suppose the could be one like that on nuts. You'd have to decide whether it is a very resticted topic on the botanical idea of a nut which doesn't contain most of what people mean by a nut or a wider one like the article on trees. Would you include pine nuts, coconuts peanuts, and the stones of drupes like almonds or pecans or plums? NadVolum (talk) 14:33, 25 September 2024 (UTC)[reply]

The plan is for them to go back to Nut_(food) as part of the unmerge. The unmerge discussion is here. AlmostReadytoFly (talk) 08:51, 26 September 2024 (UTC)[reply]

Measure relative UVB / UVC intensity

For SODIS water disinfection I'm interested in testing how much UVB and UVC passes through various types of plastic and other materials. I don't care so much about absolute levels as relative intensity compared to unfiltered sunlight. I'd also like to check out whether my cheap sunglasses are letting any UV through. I see this device says peak spectral response 300-350mm which is describes as UVA (I thought that was the A-B range). Is that sufficient, i.e. is something that transits UVA unlikely to block UVB/UVC? Thanks. 2601:644:8581:75B0:0:0:0:C813 (talk) 22:21, 25 September 2024 (UTC)[reply]

I doubt that it's any indication one way or the other, different materials can have widely different transmission spectra both within and outside the visible band; one would have to test each one specifically (if references aren't available). {The poster formerly known as 87.81.230.195} 94.1.171.3 (talk) 02:20, 26 September 2024 (UTC)[reply]
