Talk:Extremely low frequency

Frequency range
The frequency range quoted (3-30 Hz) seems to be in error. According to the IARC Monograph on Static and Extremely Low-Frequency (ELF) Electric and Magnetic Fields, the "extremely low-frequency (ELF) range [is from] (3–3000 Hz)." ralian 03:28, 24 October 2007 (UTC)

You are correct. 30-3000 Hz should be the correct frequency listed. Military classifies this frequency range as ELF. Plus, converting 3-30 Hz into wavelength only gives you a tiny portion of the ELF range. —Preceding unsigned comment added by 24.18.251.179 (talk) 03:29, 8 April 2008 (UTC)

"Despite the extremely high electrical conductivity of salt water, the water's density shields submarines from most electromagnetic communications."

Don't conductors stop EM waves? - Omegatron 14:58, Aug 16, 2004 (UTC)

It's not quite that simple, but yes, I think the high conductivity of water serves to reduce the wave transmission. I'd need to do the maths, though, before I feel secure in changing the article. Kaet

Just was about to ask the same as Omegatron. So, Kaet, did you do the maths? Simon A. 13:21, 7 Sep 2004 (UTC)

I asked this question of the chairman of the Physics Department back at my college in the mid 80's. Short answer is that conductivity is a function of frequency, not an absolute quantity. User:David Battle

Generally, the higher the conductivity of a substance, the less electromagnetic radiation will pass through it. From my copy of Griffiths' "Introduction to Electrodynamics" (p. 394), the skin depth (the characteristic depth to which an EM wave penetrates) is

$$d = \frac{\sqrt{2/(\epsilon\mu\omega^2)}}\sqrt{\sqrt{1+(\frac{\sigma}{\epsilon\omega})^2}-1}$$

(my apologies, I don't know how to format math here yet). In the limit of high conductivity and low frequency this simplifies to $$d = \sqrt{\frac{2}{\omega\sigma\mu}}$$, where sigma is conductivity. You can find this formula also in Jackson's "Classical Electrodynamics" (p. 220). So, when conductivty becomes large (compared to some "characteristic conductivity" that depends on frequency), EM waves don't penetrate far. As a sanity check, empty space is completely non-conductive and transmits EM waves perfectly, while a conducting Faraday cage is used to shield from radiation. I hope that helps. -- Unperson, of everything2 fame

effects on the brain
Can ELF waves effect brainwaves?

http://www.borderlands.com/archives/arch/elf.htm

 * From reading the information the author of that article gave, which is the same experiment in the link above, incidentally, there is a big problem with the experimental setup.

The author, Walonick, sated the following: "The transducer was a 24" diameter hand-wound coil, consisting of 1000' of #25 magnetic wire. The coil had a DC resistance of 32.4 ohms. It was mounted on a 26" square piece of bakalite board for stability."

This describes the antenna. Further down the article:

"The voltage fed to the coil was 3.1 VAC (RMS). The coil was positioned 18" in front of the subjects head. The outputs from the ELF transmitter (function generator) and the  brain wave monitor were fed directly into the computer A to D  board, allowing both to be displayed on the computer monitor (and  recorded on disk) simultaneously."

There are several fundamental issues with this experiment, the first being that unless it was a Placebo/double blind trial, it was non-functional.

The coil described would have an inductance of about 5mH, which would have a resonant frequency of 2kHz. As this is being used as an antenna, I've computed a -69dB Gain. The input is 3.1VAC RMS, with a source impedance of 600 Ohms for the signal generator given. The impedance mismatch of 30:1 will cause even worse signal out of the antenna, essentially none. The Radiated power from the coil would be in the picowatts, with more signal radiating from the connection leads.

The measurements by the EEG changing were most likely due to capacitive coupling of the cables leading between the EEG and the coil, and not anything from the brain itself.

ELF Transmissions require a tremendous amount of power, and ridiculously long antennas to propagate. A loop antenna isn't of much use below 500kHz, let alone 5-15 Hz.

In other words, from an engineer: The information in the link given is incorrect due to interference, with a dose of the experimenter finding what he wanted to find, rather than any actual change in the minds of the very small sample of volunteers. 21:26, 10 July 2010 (UTC) —Preceding unsigned comment added by 8r455 (talk • contribs)

Can somone verify this?
surely not: "The transmitted signal is often used to track the pig should it become stuck in the pipeline." 118.90.109.249 (talk) 09:35, 4 July 2008 (UTC) ?

 * Sounds reasonable to me. It's not talking about pigs, its talking about Pipeline inspection gauges (Pig) and Pigging. "Communications are achieved by an extremely low frequency electromagnetic system that performs efficiently in both steel and seawater media. During pigging operations the plug emits a beacon that permits tracking. The accuracy of plug positioning is within +/- 100mm."Subsea Pipeline Solution Pipeline & Gas Journal, August, 2000. Try googling pipeline pig extremely low frequency for more items. --Dual Freq (talk) 14:26, 4 July 2008 (UTC)

 * I'm considering a rewrite of this sections that is a bit more clear and accurate regarding the application. I would like to delete the term "Pipeline Inspection Gauge" as it is misleading.  A pig is a vehicle that may or may not include gauges.  The locating function is not just for locating stuck pigs but also for verifying or refining location accuracy of the pigs data.  All of this is made fairly clear in the article on pigging.  The text that I am considering for this paragraph is "Transmitters in the 22 Hz range are also used in pigging. The signal is generated as an alternating magnetic field, and the transmitter is mounted to, or to part of, the "pig". The pig is pushed through a pipeline mostly made of metal. The ELF signal can be detected through the metal allowing it's location to be detected by receivers located outside of the pipe.[31] --Taylor316 (talk) 15:04, 1 January 2019 (UTC)

What about other ELFs? I've added a section that explains ELFs range from 0 to 100 Hz and includes examples regarding hydro electricity at 60 hz. --CyclePat (talk) 16:20, 20 April 2009 (UTC)

 * See Super low frequency for 30-300 Hz. Sometimes the technical use of therms like ELF, UHF etc does not follow closely the 3/30/300 classification. Sv1xv (talk) 16:39, 20 April 2009 (UTC)

 * What is the 3/30/300 classification? Electromagnetic therapy often uses the term ELF to describe Extremely low frequency.  Some articles on electromagnetic radiation and health also utilize the term. --CyclePat (talk) 22:39, 20 April 2009 (UTC)
 * Is it 3 to 30 ELF, 30 to 300 SLF? Hence 3/30/300? --CyclePat (talk) 22:40, 20 April 2009 (UTC)

 * By 3/30/300 I mean exactly that: LF: 30-300 kHz, MF: 300-3000 kHz, HF: 3-30 MHz, VHF: 30-300 MHz, UHF: 300 MHz - 3 GHz etc. See also Template:Radio spectrum. Sv1xv (talk) 04:10, 21 April 2009 (UTC)

ELF vs SLF vs ULF confusion
As a first time reader, this article is confusing. If ELF range is 3-30Hz then why does the article talk about military applications which are actually in the SLF range? If the 'military speak' doesn't line up with the scientific classification this should be made explicit.

Also the article needs to better explain how we can broadcast in this range if the antenna (in theory) needs to be thousands of kms long... ! It doesn't make this clear at the moment. There must either be a solution (workaround), or the military actually uses higher frequencies, e.g. SLF or ULF? Amilnerwhite (talk) 23:40, 10 November 2009 (UTC)

Recent changes
I have reverted CyclePat's recent changes as fail to meet our criteria on several points. Per WP:UNDUE, the additions and new sections give undue prominence to single primary sources or WP:FRINGE sources, and some of the content is itself WP:FRINGE - hence fails our NPOV requirement. Further, they are not all WP:RS, and WP:MEDRS for medical claims, and therefore not suitable. This article should not be used as a WP:COATRACK or for WP:ADVOCACY, and must stick to WP:NPOV. If you feel some of these edits have merit please justify here, with RS as appropriate. Discussion is better than editwarring. Thanks, Verbal chat  13:03, 12 February 2010 (UTC)
 * The new section is also a clear violation of WP:SYNTH, as well as not being very clear. CyclePat, please self revert and discuss these edits and additions, otherwise the article will have to be tagged as POV and OR. Verbal chat  13:07, 12 February 2010 (UTC)
 * I'll be happy to give you a phone call to discuss this. We can record the conversation and publish it here on the talk page. In the meantime,
 * 1) Since when does the addition of "new sections" give undu prominence to single primary sources? And why?  If you explained the principle and an example, perhaps we could be on our way to a better start. In fact, per WP:UNDUE, I could argue that what I'm doing is correct. That's because "Neutrality requires that the article should fairly represent all significant viewpoints that have been published by a reliable source, and should do so in proportion to the prominence of each). However, please explain, why you believe this.  The majority viewpoint, in our case the 3 to 30 hz, is simply not well referenced. If I could find more "peer-reviewed" information about that, then I would be putting it in. (Is this what you are alluding too?)
 * 2)HAHAHAHAHA! LOL! Fringe sources... Yeah... the World Health Organization. And NASA... and the Government of Canada.... LOL... I think you may have watched to many X-files TV series. (b.t.w.: isn't there a popular episode about how the military tested ELF and this guy had to keep driving West because it influence his body functions?)
 * 3)This is not a coat rack. I'm simply describing what well sourced, peer-reviewed journals say, as well as government agencies, regarding ELF. (I will say this one, ELF is simply a frequency.)  The WP:UNDUE POV, which I've quickly analyzed, may be the military communications. ELF is used in many fields (pun intended), and hence, military communications is simply one branch of ELF. If you are concerned about this article becoming a medical article, as, in past, you have display dissent towards articles that utilize medical "peer-reviewed" journal, please WP:AGF and note that these are relevant, and pretty much the "majority" or easily accessible information regarding ELF. If you have some more information and references, please do add them. Thank you. And, you may refer to me in the first person... Thank you Verbal.
 * 4) Wow! A violation of synth? NO, I don't think so. So please, do elaborate!!  If the description of ELF is "unclear", it is simply because the facts (or opinions) of what quantifies as the frequencies of ELF are, in of itself, unclear between scientist. Ideally, we would find a source that says this.

 * I'm not seeing the big problem, what with WHO and NASA cites added. Binksternet (talk) 13:59, 12 February 2010 (UTC)

 * As long-winded as Pat is, and he -always- is, the 3-30hz isn't well referenced. You can see that both OSHA in the US and WHO define it as < 300hz, others as < 1000hz  Not so cut and dry, although Guyonthesubway (talk) 16:11, 12 February 2010 (UTC)

 * I do not see an issue with the additional content CyclePat has added. The primary use of the ELF band has been for communicating with submarines, using VERY short messages.  The exact details of the communication methods, by the US in particular, are NOT for public/global exposure for obvious reasons, which leads to a lack of sources.  This leaves legacy information/experiments as the only sources.   Nearly all "Health Aspects" of low frequency EM waves in the US have been carried out in the 50-60Hz Range, which is in the SLF range, conducted on families near power lines, etc.  These are above the "Traditional" ELF Band.  I am new here somewhat, so forgive my misunderstandings.  I feel most of the content with related flags should be in the SLF section.    I would suggest the generation of a "Wiki Standard EM spectrum chart", and decide on a solid range of what constitutes Extremely Low Frequency.  The ITU bands and the US Bands are quite close.  The Planck-Einstein equation shows that ELF transmissions have low energy, compared to FM radio, which we are bombarded with in much heavier doses.  Any study of higher frequencies and health would be irrelevant unless applied directly to the ELF spectrum.   8r455 (talk) 20:46, 10 July 2010 (UTC)

Antenna Length
Antennas are used to amplify voltage (amplitude) by means of electrical resonance through induction. Any moving electric field will result in a corresponding magnetic field which emanates into free space indefinitely. An antenna is only required if the threshold of the detection equipment is below the amplitude of the transmitted wave.

As antennas function on the principle of resonance, for a properly tuned antenna, its size needs to be related to the wavelength. If not, electrical resonance won't occur and the signal will not be amplified.

This is why even small voltage potentials, in the range of 0-500Hz, produce ELF waves. —Preceding unsigned comment added by 89.241.157.213 (talk) 08:47, 13 July 2010 (UTC)

 * Please explain with the aid of diagrams how you would put an antenna thousands of miles long on a submarine. Herr Gruber (talk) 19:04, 13 November 2014 (UTC)

 * Antennas do not have to be physically large to work, particularly if one is only concerned with receiving and can tolerate inefficiencies. Transistor radios use small ferrite bar antennas, only tens of centimeters long, to receive AM broadcasts with wavelengths just shy of 600 meters.  The transmitters submarines tune to generate very strong signals, like broadcast stations.  I wouldn't be the least bit surprised if submarines use some variation of a magnetic loop antenna to receive ELF transmissions from ground stations.
 * –Sparkgap (talk) 16:56, 22 October 2015 (UTC)

 * Of course they can receive ELF signals, that's the entire reason the system exists in the first place.

50 Hz ? But that's the frequency of the electricity in Europe
In the "Comparison of international policies on electromagnetic fields" - Table 1: Exposure limits for the general public for electromagnetic fields in inhabited areas in member states of the European Union and selected industrial nations outside the European Union (situation April 2011) [http%3A%2F%2Fec.europa.eu%2Fhealth%2Felectromagnetic_fields%2Fdocs%2Femf_comparision_policies_en.pdf&usg=AFQjCNFLsYCw9VT_vALvnReZscUn5agdIA&sig2=iv0tjzhwYMoARjwGKL5GJg EU emf_comparision_policies_en.pdf] - all EU member states are ranked for their exposure limits for the 50 Hz (ELF), 900 MHz (GSM), 1800 MHz (GSM), 2100 MHz (UMTS). I think the 50 Hz is mentioned because of radiation coming from powerlines and transformers, isn't it? It drops dead after just a couple of centimeters, and in the transformers to higher voltages afer a coule of 10 cm, but anyway. --SvenAERTS (talk) 19:07, 9 September 2015 (UTC)
 * Exactly, and there's nothing in the human body that has a preference for certain frequencies. It's not like our hearts start failing at 50Hz, but not at 40Hz or 70Hz. That makes it all the more dubious to study what power-lines and transformers put out there and segment out the frequency of the source.

Association with childhood leukemia
It is not acceptable to make a claim of this seriousness in WP without a reliable source. It is just scaremongering. Any claims need to be accompanied by field strength figures at least to have any real meaning.Martin Hogbin (talk) 16:41, 21 November 2015 (UTC)

 * Furthermore, it quotes research about RF radiation up to 100 kiloHertz. Well sorry, this could mean they measured leukemia in humans living near FM radio-transmitting antennas (or similar). This leukemia-hype has nothing going for its magnetic fields correlation, and should really be correctly put in WP. This has been further explained (and debunked) in counter-research done to disprove its relation. It's really weird how people claiming 'dangers' from 5G even mix that with magnetic field or lower frequency radiation. They're not the same, and it's not useful if you want to be taken seriously.

The solar 22-year magnetic cycle
A changing EM field will radiate; not much because of the low frequency but then the magnetic field is strong. The frequency and wavelength are easy to calculate. The frequency will be 1/22 per year and the wavelength will be 22 ly. I agree that a source would be good. Martin Hogbin (talk) 09:36, 5 January 2016 (UTC)

 * Similarly, you could mention loudspeakers, for example in a laptop, bluetooth speaker, or studio. Use any Tesla or Gauss meter and see what's actually there. It all disproves the hysteria around magnetic fields being dangerous. Heck, if they were, I was a fan of strong magnets ever since age 5 or thereabouts, I'd be unhealthy as f. now if that were remotely true. I'm age 53 now. No cancer, nothing that could even be pointed to having suffered a lot of magnetic field radiation. Further than that, I have messed with FM-transmitters, built my own, had them in my bedroom for years when I was young, with a growing amount of power (up to 100 Watt FM HF radiation). It did not have any effect whatsoever. Sure, it's an N1 study, but still, if it were as dangerous to DNA as they claim it is, my daughter (now 8) would be a complete retard, which she's not. She skipped a class already. Oh and she loves playing with magnets! 95.97.55.62 (talk) 10:55, 19 November 2019 (UTC)

This article needs a section on Detection and Reception of ELF signals
What I said. It's pretty obvious that we aren't detecting these with 3000 km long antennae. It also seems clear to me that oscillations of a charge (or a magnet?) will create these. In other words (and this is original research on my part), when I rub my feet on a carpet and accumulate a static charge, I am also generating ELF radiation. Am I not? How about spinning electro- and permanent magnets (found in most motors)? This isn't at all clear from this article (for someone who can't read between the lines).Abitslow (talk) 19:14, 11 June 2016 (UTC)
 * Well yes, you nailed it; That's because most of it is hogwash, BS, nonsense, hysteria over tech-phobia. Check how most of the sources that claim dangers are people that haven't finished a physics or tech study in any field. It's the people that can't handle computers, internet, the people that don't understand code, machines, electronics, radio-waves, and because they're so inapt at the field of knowledge, they try and make it a bad thing. So as to no longer have to deal with people telling them they should use internet because it's handy for research, science and progress. "I don't get it, I'm too stupid and lazy to learn new technologies or to operate equipment I don't know, so I'll think of something that makes it bad and unhealthy to use".

Image dispute
Both images has her clearly visible without being blurry. 1989 is better because of the film's release date. The actress looks similiar to her appearence in the film, which is helpful to the reader. Sebastian James what's the T? 20:33, 22 May 2019 (UTC)
 * I agree with Sebastian James as the photo is more relevant to the article. --NikkeKatski [Elite] (talk) 20:38, 22 May 2019 (UTC)
 * The current image has her in a still, standing position. The former one is a picture taken of her walking a red carpet. She does not look similar to her appearance in the film, and how is that "helpful to the reader"? QuestFour (talk) 20:48, 22 May 2019 (UTC)
 * "Walking a red carpet" is nothing to do with the image quality here, which is not blurry and definitely fine. Did you actually watch the film? The current image is showing herself older, maybe that's why it is "helpful to the reader". Sebastian James what's the T? 21:01, 22 May 2019 (UTC)
 * Nobody mentioned anything about the images being blurry. An image of her standing is better suited than a one of her walking. Also, the current image is the one used in the infobox of her article anyway, so I don't think there will be any confusion with the reader on that. QuestFour (talk) 21:21, 22 May 2019 (UTC)
 * It is not clear whether she is walking or not because the image is cropped. And there's nothing wrong with an image of a walking person. This is not an infobox for a person, which means that it doesn't need an updated picture of that person. I don't see a point why did you even mentioned this and see it as a reasonable explanation for your edit. Sebastian James what's the T? 23:13, 22 May 2019 (UTC)
 * Actually, it is very clear that she's walking. There's nothing wrong with that if it was the only picture available of her, but there's a picture of her in a still, standing position and that's more suitable. I only brought up the fact that it is the main infobox image of her article because you implied that the reader might not be able to recognize a newer picture because she's "older". QuestFour (talk) 23:54, 22 May 2019 (UTC)
 * Walking or standing still, it doesn't matter. Both pictures show the actress equally good for representation, except for the fact that 1989 one is more relevant to the article. I am surprised that you are seeing your comment logical, though I shouldn't be since you have been also adding unsourced information with grammatical errors. The reader of the page is here for a 1997 film, therefore, if they are to be shown a photograph of the lead actress, they will expect to see a picture of her similiar to her appearence in the film. This has to do nothing with "standing still". Even the image on Commons shows that it is only used for Sigourney Weaver article on all the different Wikipedia languages, except for your edit of course. Sebastian James what's the T? 13:52, 23 May 2019 (UTC)
 * It does matter, one is more preferable to the other. You keep bringing up the year argument even though it has no relevance whatsoever, your reason is that it won't cause confusion and will "help the reader". I explained to you why this won't be a problem. The other points you brought up about the Titanc edits and the image use on commons have nothing to do with this discussion, and I'm confused as to why you even mentioned them. QuestFour (talk) 19:26, 24 May 2019 (UTC)
 * Probably because you are not here for constructive contribution? There isn't a preferable one in this case because walking or standing still "has no relevance whatsoever", and Commons was an example of usage. I suggest you read guidelines, such as MOS:MOVIE, before you get blocked. Sebastian James what's the T? 10:50, 25 May 2019 (UTC)
 * There is, as I have explained to you before, but it seems that you're not listening. You only see what suites your side of the argument, thus you see the time period as relevant and the position of the pictured actress as not. What pages the image is used on have nothing to do with anything, and the MOS you linked does not say anything about the time period of the photo. QuestFour (talk) 04:37, 31 May 2019 (UTC)
 * He does have a point about there not really being any rule against a picture from a different time period. But regardless why is an edit war happening over it? I don't think its really important enough for an RFC much less an edit war. --NikkeKatski [Elite] (talk) 12:17, 31 May 2019 (UTC)
 * Never said that there was a rule against a picture from a different time period, so... Also, MOS:MOVIE and other guidelines were examples because the editor has been making unconstructive changes, such as adding unsourced information to film articles. Sebastian James what's the T? 13:46, 31 May 2019 (UTC)
 * If there's no rules, why are you edit warring over this? In pictures of people, a standing still/pose position is preferable over a walking/mobile position, that's not a rule but simply common sense. QuestFour (talk) 23:40, 31 May 2019 (UTC)
 * Good story. Adding unsourced content is also more "preferable" than sourced ones to you, am I correct? Sebastian James what's the T? 12:40, 1 June 2019 (UTC)
 * Answer my question, stop changing the subject. QuestFour (talk) 14:47, 1 June 2019 (UTC)
 * You are funny. I am not obliged to answer your question. The current image existed long before you changed it, so you are edit warring over it. At this point, you should've already dropped it. Sebastian James what's the T? 15:32, 1 June 2019 (UTC)
 * Actually, you are. You reverted constructive edits with a motive that I explained, thus you are obligated to justify your reverts. Both NikkeKatsi and myself have explained to you that your arguments regarding the time period are irrelevant. Unless you have a valid reason why the image shouldn't be restored, I'm going to have to report you to an admin and undo your revision. Stop wasting other editors' time, this is your only and final warning. QuestFour (talk) 20:21, 1 June 2019 (UTC)
 * Are you sure you have read NikkeKatsi's comment? Because they say "He does have a point about there not really being any rule against a picture from a different time period." and I said "Never said that there was a rule against a picture from a different time period". They have never said anything about "irrelevant", and you still don't have any other editors who support your opinion. Why are you still typing smarmy sentences and edit warring? As anyone can see, your reason to change the image hasn't found any resolution. Per WP:BRD, you should've come here when I reverted you in the first place, and I've already reported you to an admin. Just walk away and get over it. Sebastian James what's the T? 10:05, 2 June 2019 (UTC)
 * FWIW, IMHO the original image was fine, and I can't see any rationale for replacing it with the other. The fact that she may be standing still as opposed to walking seems supremely inconsequential, whereas the fact that the original is closer in time to the movie is relevant. Cheers!

Addax

The addax (Addax nasomaculatus), also known as the white antelope and the screwhorn antelope, is an antelope native to the Sahara Desert. The only member of the genus Addax, it was first described scientifically by Henri de Blainville in 1816. As suggested by its alternative name, the pale antelope has long, twisted horns – typically 55 to 80 cm in females and 70 to 85 cm in males. Males stand from 105 to 115 cm at the shoulder, with females at 95 to 110 cm. They are sexually dimorphic, as the females are smaller than the males. The colour of the coat depends on the season – in the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders; in the summer, the coat turns almost completely white or sandy blonde.

The addax mainly eats grasses and leaves of any available shrubs, leguminous herbs and bushes. They are well-adapted to exist in their desert habitat, as they can live without water for long periods of time. Addax form herds of five to 20 members, consisting of both males and females. They are led by the oldest female. Due to its slow movements, the addax is an easy target for its predators: humans, lions, leopards, cheetahs and African wild dogs. Breeding season is at its peak during winter and early spring. The natural habitat of the addax are arid regions, semideserts and sandy and stony deserts.

The addax is a critically endangered species of antelope, as classified by the IUCN. Although extremely rare in its native habitat due to unregulated hunting, it is quite common in captivity. The addax was once abundant in North Africa; however it is currently only native to Chad, Mauritania, and Niger. It is extirpated from Algeria, Egypt, Libya, Sudan, and Western Sahara, but has been reintroduced into Morocco and Tunisia.

Taxonomy and naming
The scientific name of the addax is Addax nasomaculatus. This antelope was first described by French zoologist and anatomist Henri Blainville in 1816. It is placed in the monotypic genus Addax and the family Bovidae. Henri Blainville observed syntypes in Bullock's Pantherion and the Museum of the Royal College of Surgeons. English naturalist Richard Lydekker stated their type locality to be probably Senegambia, though he did not have anything to support the claim. Finally, from a discussion in 1898, it became more probable that British hunters or collectors obtained the addax from the part of the Sahara in Tunisia.

The generic name Addax is thought to be obtained from an Arabic word meaning a wild animal with crooked horns. It is also thought to have originated from a Latin word. The name was first used in 1693. The specific name nasomaculatus comes from the Latin words nasus (or the prefix naso-) meaning nose, and maculatus meaning spotted, referring to the spots and facial markings of the species. Bedouins use another name for the addax, the Arabic bakr (or bagr) al wahsh, which literally means "the cow of the wild". That name can be used to refer to other ungulates as well. The other common names of addax are "white antelope" and "screwhorn antelope".

Genetics
The addax has 29 pairs of chromosomes. All chromosomes are acrocentric except for the first pair of autosomes, which are submetacentric. The X chromosome is the largest of the acrocentric chromosomes, and the Y chromosome is medium-sized. The short and long arms of the pair of submetacentric autosomes correspond respectively to the 27th and 1st chromosomes in cattle and goats. In a study, the banding patterns of chromosomes in addax were found to be similar to those in four other species of the subfamily Hippotraginae.

History and fossil record
In ancient times, the addax occurred from northern Africa through Arabia and the Levant. Pictures in a tomb, dating back to 2500 BCE, show at least the partial domestication of the addax by the ancient Egyptians. These pictures show addax and some other antelopes tied with ropes to stakes. The number of addax captured by a person were considered an indicator of his high social and economic position in the society. The pygarg ("white-buttocked") beast mentioned in Deuteronomy 14:5 is believed to have been an addax. But today, excess poaching has resulted in the extinction of this species in Egypt since the 1960s.

Addax fossils have been found in four sites of Egypt – a 7000 BCE fossil from the Great Sand Sea, a 5000–6000 BCE fossil from Djara, a 4000–7000 BCE fossil from Abu Ballas Stufenmland and a 5000 BCE fossil from Gilf Kebir. Apart from these, fossils have also been excavated from Mittleres Wadi Howar (6300 BCE fossil), and Pleistocene fossils from Grotte Neandertaliens, Jebel Irhoud and Parc d'Hydra.

Physical description
The addax is a spiral-horned antelope. Male addaxes stand from 105 to 115 cm at the shoulder, with females at 95 to 110 cm. They are sexually dimorphic, as the females are smaller than the males. The head and body length in both sexes is 120 to 130 cm, with a 25 to 35 cm long tail. The weight of males varies from 100 to 125 kg, and that of females from 60 to 90 kg.

The coloring of the addax's coat varies with the season. In the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders. In the summer, the coat turns almost completely white or sandy blonde. Their head is marked with brown or black patches that form an 'X' over their noses. They have scraggly beards and prominent red nostrils. Long, black hairs stick out between their curved and spiralling horns, ending in a short mane on the neck.

The horns, which are found on both males and females, have two to three twists and are typically 55 to 80 cm in females and 70 to 85 cm in males, although the maximum recorded length is 109.2 cm. The lower and middle portions of the horns are marked with a series of 30 to 35 ring-shaped ridges. The tail is short and slender, ending in a puff of black hair. The hooves are broad with flat soles and strong dewclaws to help them walk on soft sand. All four feet possess scent glands. The life span of the addax is up to 19 years in the wild, which can be extended to 25 years under captivity.

The addax closely resembles the scimitar oryx, but can be distinguished by its horns and facial markings. While the addax is spiral-horned, the scimitar oryx has decurved 127 cm long horns. The addax has a brown hair tuft extending from the base of its horns to between its eyes. A white patch, continuing from the brown hair, extends until the middle of the cheek. On the other hand, the scimitar oryx has a white forehead with only a notable brown marking: a brown lateral stripe across its eyes. It differs from other antelopes by having large, square teeth like cattle and lacking the typical facial glands.

Parasites
The addax is most prone to parasites in moist climatic conditions. Addaxes have always been infected with nematodes in the Trichostrongyloidea and Strongyloidea superfamilies. In an exotic ranch in Texas, an addax was found host to the nematodes Haemonchus contortus and Longistrongylus curvispiculum in its abomasum, of which the former was dominant.

Behavior and ecology
These animals are mainly nocturnal, particularly in summer. In the day, they dig into the sand in shady locations and rest in these depressions, which also protect them from sandstorms. Addax herds contain both males and females, and have from five to 20 members. They will generally stay in one place and only wander widely in search of food. The addax has a strong social structure, probably based on age, and herds are led by the oldest female. Herds are more likely to be found along the northern edge of the tropical rain system during the summer and move north as winter falls. They are able to track rainfall and will head for these areas where vegetation is more plentiful. Males are territorial and guard females, while the females establish their own dominance hierarchies.

Due to its slow movements, the addax is an easy target for predators such as humans, lions, leopards, cheetahs and African wild dogs. Caracals, servals and hyenas attack calves. The addax is normally not aggressive, though individuals may charge if they are disturbed.

Adaptations
The addax is amply suited to live in the deep desert under extreme conditions. It can survive without free water almost indefinitely, because it gets moisture from its food and dew that condenses on plants. Scientists believe the addax has a special lining in its stomach that stores water in pouches to use in times of dehydration. It also produces highly concentrated urine to conserve water. The pale colour of the coat reflects radiant heat, and the length and density of the coat helps in thermoregulation. In the day the addax huddles together in shaded areas, and on cool nights rests in sand hollows. These practices help in dissipation of body heat and saving water by cooling the body through evaporation.

In a study, eight addaxes on a diet of grass hay (Chloris gayana) were studied to determine the retention time of food from the digestive tract. It was found that food retention time was long, taken as an adaptation to a diet including a high proportion of slow fermenting grasses; while the long fluid retention time could be interpreted to be due to water-saving mechanisms with low water turnover and a roomy rumen.

Diet
The addax lives in desert terrain where it eats grasses and leaves of what shrubs, leguminous herbs and bushes are available. Primarily a grazer, its staple foods include Aristida, Panicum, and Stipagrostis, and it will only consume browse, such as leaves of Acacia trees in the absence of these grasses. It also eats perennials which turn green and sprout at the slightest bit of humidity or rain. The addax eats only certain parts of the plant and tends to crop the Aristida grasses neatly to the same height. By contrast, when feeding on Panicum grass, the drier outer leaves are left alone while it eats the tender inner shoots and seeds. These seeds are important part of the addax's diet, being its main source of protein.

Reproduction
Females are sexually mature at 2 to 3 years of age and males at about 2 years. Breeding occurs throughout the year, but it peaks during winter and early spring. In the northern Sahara, breeding peaks at the end of winter and the beginning of spring; in the southern Sahara, breeding peaks from September to October and from January to mid-April. Each estrus bout lasts for one or two days.

In a study, the blood serum of female addaxes was analyzed through immunoassay to know about their luteal phase. Estrous cycle duration was of about 33 days. During pregnancy, ultrasonography showed the uterine horns as coiled. The maximum diameters of the ovarian follicle and the corpus luteum were 15 mm and 27 mm. Each female underwent an anovulatory period lasting 39 to 131 days, during which there was no ovulation. Anovulation was rare in winter, which suggested the effect of seasons on the estrous cycle.

Gestation period lasts 257–270 days (about nine months). Females may lie or stand during the delivery, during which one calf is born. A postpartum estrus occurs after two or three days. The calf weighs 5 kg at birth and is weaned at 23–29 weeks old.

Habitat and distribution
The addax inhabits arid regions, semideserts and sandy and stony deserts. They can live in extremely arid areas, with less than 100 mm annual rainfall. It also inhabits deserts with tussock grasses (Stipagrostis species) and succulent thorn scrub Cornulaca. Formerly, the addax was widespread in the Sahelo-Saharan region of Africa, west of the Nile Valley and all countries sharing the Sahara Desert; but today the only known self-sustaining population is present in the Termit Massif Reserve (Niger). However, there are reports of sightings from the eastern Air Mountains (Niger) and Bodélé (Chad). Rare nomads may be seen in northern Niger, southern Algeria and Libya; and the addax is rumoured to be present along the Mali/Mauritania border, though there have been no confirmed sightings. The addax was once abundant in North Africa, native to Chad, Mauritania and Niger. It is extinct in Algeria, Egypt, Libya, Sudan and the Western Sahara. It has been reintroduced into Morocco and Tunisia.

Threats and conservation
Declines in the population of the addax have been ongoing since the mid-1800s. More recently, addaxes were found from Algeria to Sudan, but due mainly to overhunting, they have become much more restricted and rare.

Addaxes are easy to hunt due to their slow movements. Roadkill, firearms for easy hunting and nomadic settlements near waterholes (their dry-season feeding places) have also decreased their numbers. Moreover, their meat and leather are highly prized. Other threats include chronic droughts in the deserts, habitat destruction due to more human settlements and agriculture. Fewer than 500 individuals are thought to exist in the wild today, most of the animals being found between the Termit area of Niger, the Bodélé region of western Chad, and the Aoukar in Mauritania.

Today there are over 600 addaxes in Europe, Yotvata Hai-Bar Nature Reserve (Israel), Sabratha (Libya), Giza Zoo (Egypt), North America, Japan and Australia under captive breeding programmes. There are thousands more in private collections and ranches in the United States and the Middle East. Addaxes are legally protected in Morocco, Tunisia, and Algeria; hunting of all gazelles is forbidden in Libya and Egypt. Although enormous reserves, such as the Hoggar Mountains and Tasilli in Algeria, the Ténéré in Niger, the Ouadi Rimé-Ouadi Achim Faunal Reserve in Chad, and the newly established Wadi Howar National Park in Sudan, cover areas where the addax previously occurred, some do not keep addaxes at the present time because they lack the resources. The addax has been reintroduced into Bou-Hedma National Park (Tunisia) and Souss-Massa National Park (Morocco). Reintroductions in the wild are ongoing in Jebil National Park (Tunisia) and Grand Erg Oriental (the Sahara), and another is planned for Morocco.

I'd be surprised if Clayton's PR department were that cack-handed, so I'm guessing this is somebody from SMR who has got frightened by some sort of non-disclosure agreement the railway has signed with Claytons, and has over-reacted. Either way, it has nothing to do with Wikipedia, and there is plenty of sourcing for the existence of the locos. I've even found one on Clayton's own web site. -- chris_j_wood (talk) 09:16, 31 August 2022 (UTC)
 * Thanks! BTW: adding the after you have signed and published doesn't send any wp:Ping. You need to add the ping and a second signature. It doesn't ping if you erase your signature and resign either. I've tried a large number of combinations to no avail. Cheers Adakiko (talk) 09:25, 31 August 2022 (UTC)

Proposed deletion of London Rail

The article London Rail has been proposed for deletion because of the following concern: "Less than 10 sources, all prior to 2015. Main body includes seemingly irrelevant information (e.g. about 'London Trams'), so article does not seem up-to-date, or relevant. See talk page for further insight from User:Jackiespeel."

While all constructive contributions to Wikipedia are appreciated, pages may be deleted for any of several reasons.

You may prevent the proposed deletion by removing the notice, but please explain why in your edit summary or on the article's talk page.

Please consider improving the page to address the issues raised. Removing will stop the proposed deletion process, but other deletion processes exist. In particular, the speedy deletion process can result in deletion without discussion, and articles for deletion allows discussion to reach consensus for deletion.

 * - Already turned into a redir, but I don't understand how this disambiguation page met the speedy deletion criteria quoted above. It doesn't end (disambiguation) so the first and third bullet points don't apply. And as Ramsden, Orpington clearly does exist, bullet point two doesn't apply either. Unless I'm missing something, this should never have been considered for speedy deletion (or at least not under WP:CSD). That said, what this clearly shows is that nine years ago I intended to create an article for the other (and, from a historical perspective, more significant) Ramsden Estate and then didn't (probably got side-tracked and forgot). I think I will go and do what I should have done then, and create that article, then reinstate the dab. -- chris_j_wood (talk)

Category:Borough of Copeland
Hi Chris. Thanks for your work on articles in Category:Borough of Copeland. The edits you’ve made recently suggest you may be gradually clearing the category out, but that would need consensus. There may already be a consensus somewhere on WP, given the number of districts that have recently been abolished, in which case it’s worth linking to it in edit summaries so that folks don’t get alarmed! --Northernhenge (talk) 13:31, 7 May 2024 (UTC)

 * - That wasn't my original intent. I was working on the categories for Eskdale and Muncaster civil parishes (the first preexisting, the second created by me) and their subcategories, both on WP:EN and Commons. In doing that on WP I found a number of articles about places in those parishes that were categorised by the borough and not the civil parish, and replacing the borough categorisation with a parish categorisation seemed sensible. That is probably what you saw. It was only then that I discovered that the civil parish articles and (in the case of Eskdale) category were not themselves categorised by borough but only by county (ie. Cumbria).

 * At the point I kind of stopped, because I wasn't sure if what I was seeing was a broken hierarchy that had maybe never been set up properly, or if it was the result of somebody else starting to do what you thought I was doing top down, and not having yet got to sub-parish places. Still not sure, but there doesn't seem to be any kind of hierarchy below the new unitaries, so I suspect the heirarchy has been broken all along. I was still pondering where to go from that when I saw your message. I'd be interested in what you think; I certainly don't have enough of a plan at the moment to seek consensus for. -- chris_j_wood (talk) 14:08, 7 May 2024 (UTC)
 * Yes, replacing the borough categorisation with a parish categorisation seems sensible, especially when navigating through political/administrative hierarchies. Geographic location hierarchies are a problem with large unitary authorities. Saying that somewhere is in Westmorland & Furness doesn’t define its location very well from a national perspective, but adding a new location (new coal mine or whatever) to the category for an abolished borough doesn’t seem to make sense. It needs something in between unitary authority and parish.
 * Yes, the current hierarchies may very well be broken – there’s no shortage of broken hierarchies on wikipedia! I’ve occasionally thought of trying to fix some but the enormity of the task puts me off. --Northernhenge (talk) 15:39, 7 May 2024 (UTC)
 * We don't normally categorize by former area so apart from things like elections that are specific to the district it probably shouldn't contain any other pages.  Crouch, Swale  ( talk ) 17:36, 7 May 2024 (UTC)

Imaginary election results
Hi, re and similar edits. In this particular case, the two constituencies have about 75% area in common, and the outgoing MP for Wantage is a candidate for election in Didcot and Wantage. TV and radio news reports have also been treating them as the same constituency with a new name. Accordingly, I think that it's fair to say that the seat is presently held by the Conservatives. -- Red rose64 🌹 (talk) 18:34, 4 June 2024 (UTC)

 * - I've no problem with that logic where it is what the article(s) in question say. There are plenty of cases where existing constituencies have boundary and even name changes and we don't create a new article. Obviously that is, to a certain extent, a judgement call on the part of the article editor, and I'm not (at least in these edits) seeking to challenge that judgement. It just seems wrong to me to list a seat as being held by a particular party, then to follow the link and be told it has never been contested. After all this template is just a navigational device, and it is the encyclopaedia articles that are king.
 * So I guess what I'm saying is that I think that your views on whether Wantage and Didcot and Wantage are the same constituency or not really need to be addressed to the the editor(s) who made them separate articles. -- chris_j_wood (talk) 09:06, 5 June 2024 (UTC)
 * ps. I've changed the row title from 'Vacant' to 'Not yet contested' to clarify what we are talking about. -- chris_j_wood (talk) 09:42, 5 June 2024 (UTC)
 * Most constituencies have boundary changes of some kind. Several have minor boundary changes, and a few have got away with no changes at all. But there are some that have been renamed, despite there being no boundary change (not even minor) - for example, Brighton Kemptown becomes Brighton Kemptown and Peacehaven; Hove becomes Hove and Portslade. To take something at the other end of the scale - Aylesbury has kept the same name but the area covered is vastly different - the constituency has lost about three-quarters of its former territory (mainly in the south) to the new Mid Buckinghamshire constituency, and gained a slightly smaller area (to the north) from the former Buckingham constituency. See the two MapIt UK links here. -- Red rose64 🌹 (talk) 17:07, 5 June 2024 (UTC)
 * - I do understand all of that. But I don't think it is relevant to the changes I have been making, which are to make this navigation tool reflect the changes others have made to the articles that the navigation tool is providing navigation to. Personally, I'm not convinced why we need to show party affiliation in this tool, and I rather prefer the approach of Template:Constituencies in Wales, which simply lists the constituencies in alphabetic order. But I rather suspect that the middle of a general election is not the time to make a radical change like that. What do you think?. -- chris_j_wood (talk) 16:36, 6 June 2024 (UTC)
