editScar formation
editI am wondering whether exposure of a wound to sunlight increases , decreases or has no effect on the development of a visible, permanent scar? 67.253.78.55 (talk) 00:25, 9 July 2020 (UTC)
- This might be of interest [1] Paul venter (talk) 10:23, 9 July 2020 (UTC)
- Seattle Children's Hospital says "Scars should be carefully protected from the sun for at least 1 year after surgery or injury. Sun exposure can darken scars permanently, making them more noticeable. After about 2 weeks of healing, you can start applying sunscreen over your child's scar. Apply sunscreen in every season, not just in the summer."[2] --Guy Macon (talk) 01:25, 9 July 2020 (UTC)

"Borromée was a ?French natural history and botanical illustrator and engraver during the 1700s and 1800s". This article has ground to a halt because of a dearth of information - I can find none of the usual biographic data on the web. Possibly this was some sort of pseudonym..... It is also an Italian family name, so there might be a link. Any sort of help would be welcome. Paul venter (talk) 10:09, 9 July 2020 (UTC)
- Only fr:Clelia Grillo Borromeo, "an 18th-century Italian naturalist and mathematician".
- Clelia Borromeo 1) was not called Borromée, 2) she was not a Frenchman and 3) did not illustrate books. This one is possibly Charles [Jean Félix Borromée] Dhéré, author e.g. of "De la nutrition, considérée anatomiquement et physiologiquement dans la série des animaux", 1826, maybe the same Borromée of the drawings [[3]].2003:F5:6F0F:6500:F06A:2BDF:7CE8:C074 (talk) 12:25, 12 July 2020 (UTC) Marco PB
Quick test to detect methanol
editIs there a simple, non-laboratory test to verify whether a given alcoholic beverage (vodka, rum, etc) indeed contains ethanol and not toxic methanol (or whether methanol is present)? Thanks. 212.180.235.46 (talk) 16:40, 9 July 2020 (UTC)
- Laboratory test kits used by distillers that indicate presence of methanol by a change of color are not cheap. See [4] [5] [6].
How did the seafloor appear on the island of Fuerteventura?
editThese publications discuss the presence of seafloor rocks on the island of Fuerteventura. Does anyone know any publication that discusses how these rocks ended up on the island in the first place? It's a volcanic island and none of the sources discusses tectonic phenomena that would induce such an uplift process. Jo-Jo Eumerus (talk) 17:37, 9 July 2020 (UTC)
- I don't know how reliable this is, but according to [7]: "Some 70 million years ago... the seabed fractured, generating the output of molten rock, which on contact with water rapidly solidified... Plutonic and volcanic rocks are also mixed with marine sediments (sand and mud) that came from Africa, so that the Basal Complex is composed of different types of rocks that we explain the origin of the island of Fuerteventura... at one point (17 million years ago), this volcano submarine surfaced and showed what would be the island Fuerteventura."
- Could it be that underwater eruptions alternated with calm periods where normal seafloor was formed until eventually the volcano reached the surface?. --Guy Macon (talk) 20:31, 9 July 2020 (UTC)
- Maybe, but what would be the mechanism to get them from the seafloor to the surface? That's really the central question I am positing. Jo-Jo Eumerus (talk) 21:01, 10 July 2020 (UTC)
- The papers written about this sequence are less than clear about the mechanism. In the very similar occurrence on the island of Maio (see Casson et al. 2020), the Mesozoic sequence crops out around the margin of the central plutonic complex, which they overlie and dip away from. This may suggest that the sequence was uplifted above a laccolithic intrusion. Offshore Gabon, Cretaceous rocks are similarly uplifted above the Loiret intrusion by more than 2 km and were once exposed at the seabed. The laccolith was intruded at the interface between the oceanic basement and the sedimentary cover. Unfortunately, the only reference to that is my own paper given at the PESGB/AAPG Africa conference last year in London, which is not otherwise published so OR I'm afraid.

White worms or Maggots?
editHelp. I found these under my dogs inside water bowl. I picked up the bowl and dumped the old water and was cleaning it. I did not notice any in bowl. But was not until I flipped the bowl over that I then saw them all over the bottom moving. I went back to wear we keep his bowl and many were on the ground. His food bowl I cleaned yesterday and was next to it. But does not seem to have any. My daughters chore is to refill our dogs bowl. I am freaking out thinking she has touched them and did not realize it. She’s knows to wash her hands after, but she’s also 5. So I’m so worried we now all could have them. Can you tell what kind they are? I truly don’t know which steps to take first. I did clean them up. One was in my shirt and looked like it was making a hole through it. 😷 I’m trying to attach a photo or video. But it’s not working 😩. — Preceding unsigned comment added by 97.34.130.31 (talk) 21:05, 9 July 2020 (UTC)
- You have to upload photos to an image sharing site and then link to that. The folks at the Wikipedia:Help desk will advise if needed. Alansplodge (talk) 14:15, 10 July 2020 (UTC)
- But at a guess, rat-tailed maggots frequently appear in stagnant water; they are the the larvae of hoverflies and are harmless except as a carrier of bacteria, so don't eat them. Alansplodge (talk) 11:11, 11 July 2020 (UTC)
