Old book cover material
Comparing modern and older book covers, I've noticed that their characteristic rugged material, common particularly in the 1960s and 1970s, is hard to find in modern covers (meaning it was probably phased out at some point and replaced by smoother materials, both for hardcovers and soft covers). My WP:OR suggests it was either buckram or leatherine (or both), but could someone confirm? 212.180.235.46 (talk) 14:58, 20 January 2024 (UTC)


 * Bookbinding#Hardcover binding and Book cover may lead to some relevant information.
 * As a collector for some decades, mainly of paperback books but also having two or three thousand hardbacks of all kinds and ages, I can say that a great variety of harback cover materials have been used over the years, though this has never been a focus of my collecting, so it's difficult to generalise. {The poster formerly known as 87.81.230.195} 176.24.47.60 (talk) 20:05, 20 January 2024 (UTC)

(Esperanto, sorry, (eo) postvivado / "survival" )
Saluton, mi nepre bezonas metodon por konservi la cerbon sufiĉe bone, ke la teknologioj de la estonteco povu fari ion por la koncerna persono, sed kiu funkcias. Resume, mi havas la komencojn de vojo: vitrifixation kun 2 novigoj: la sojlo de ekscitiĝo de la sinapsoj dum vitrifixation devas esti konservita, kaj la sinapso ne devas esti detruita dum vitrifixation. Ĉu ni povus modifi la artikolon pri krioniko, por informi pri la absoluta urĝeco direkti esploradon al ĉi tiuj 2 aferoj, mi petas? Mi nepre bezonas ĝin. 78.242.18.218 (talk) 21:25, 20 January 2024 (UTC)
 * This is the English language Wikipedia. Your question may be enthralling and make perfect sense - but to a simple anglophone like me it is as comprehensible as Madarin Chinese.  Please rewrite it so that us poor editors understand you. Martin of Sheffield (talk) 21:37, 20 January 2024 (UTC)
 * Google Translate says:"Hi, I really need a method to preserve the brain well enough that the technologies of the future can do something for the person in question, but that works. In short, I have the beginnings of a path: vitrifixation with 2 innovations: the threshold of excitation of the synapses during vitrifixation must be maintained, and the synapse must not be destroyed during vitrifixation. Could we modify the cryonics article to inform about the absolute urgency to direct research to these 2 issues please? I absolutely need it."
 * Wikipedia articles are based on cited reliable sources, not a place to propose new ideas or to report your own research projects. Even opinions and analysis of previous work or the value of future direction needs to be cited. DMacks (talk) 21:48, 20 January 2024 (UTC)
 * Hello,
 * here are a few sources (most of them in French), but I can't remember if it was in them or elsewhere that a specialist said that the data of the mind was not in the way neurons are linked together, but in the threshold of excitability of synapses. She concluded immediately afterwards: "what's not just hot air is that they're going to kill people" [with vitrifixation, which has to be carried out while the person is still alive]. So I concluded that the first priority was to direct research towards preserving the excitability threshold of synapses during vitrifixation. Secondly, the synapses must be preserved.

 * Hello,
 * I'm taking the liberty of contacting you again because I need to find a source to back up the 2 emergencies so as to alert, on the WIkipedia "Cryonics" page, the urgent need to direct research towards what is necessary for the process to work and thus save people. 90.110.182.248 (talk) (former 78.242.18.218) 21:38, 23 January 2024 (UTC)

survival, question about reference desk
[translation]

Hello, why hasn't anyone replied to the last 3 messages in the "survival" section on January 20? Has the source not been found? I managed to find "https://usbeketrica.com/fr/article/nectome-veut-vous-euthanasier-avant-de-vous-rendre-immortel" 90.110.182.248 (talk) ((former 78.242.18.218)) 10:00, 26 January 2024 (UTC)
 * We're all volunteers here. Take your pick: nobody understands the question, nobody has found a good ref, nobody has had time to look at it, nobody has an interest in it. etc. I gave up because it's not clear what is being asked. Remember: this ref-desk is not a place to debate ideas and Wikipedia articles are strongly oriented towards mainstream science that has already been published in reliable other sources. There is no deadline, and specific proposals for article changes (as supported by cited sources) should be discussed on the talkpage of those articles themselves. DMacks (talk) 10:07, 26 January 2024 (UTC)
 * Apparently no one here has found a method for what you need. The simplest explanation is that no such method has been developed yet, very likely because it is just not possible with current technology. --Lambiam 10:59, 26 January 2024 (UTC)

 * Hello, I don't understand,
 * 1) I had read somewhere on the Internet a sentence in French stating that [what was needed for the mind] was the preservation of the threshold of excitability of the synapses. I did a search on Google, in French ""vitrifixation" seuil d'excitabilité des synapses" and strangely, I didn't find the text / site in question, among the 3 sites found by Google. How odd!
 * 2) I had read somewhere on the Internet a sentence in French declaring "ce qui n'est pas du vent, c'est qu'ils vont tuer des "[personnes], and by typing on Google "vitrifixation" followed by this sentence, the only result found was not the one in question... 90.110.182.248 (talk) 21:00, 27 January 2024 (UTC)

 * Hello, would it be possible for volunteers to help me write a draft of article on vitrifixation, please? I have started it here: fr:Utilisateur:Þþanon/Brouillon Þþanon (talk) 21:59, 1 February 2024 (UTC)
