Double nationality
I currently have double nationality: British and Dutch. I would like to drop one of them, preferably the country with a gloomier economic future. Between the UK and the Netherlands, which has a better economic outlook 20 years from now in terms of GDP per capita and employment etc.? 84.13.22.227 (talk) 12:25, 10 May 2015 (UTC)

Animal copulation
Is the act of copulation a learned behaviour in most animals? In mammals, perhaps as an example. I find it beyond remarkable that that most males in nature seem to know where goes what when they are ready to reproduce. I mean, had I been living in a cave all my life how would I know what goes where to ensure my genetic success? I doubt I'd have a clue. Why? Because no one ever told me! Now how an earth to males of other species figure that thing out. — Preceding unsigned comment added by 95.71.38.160 (talk) 16:26, 10 May 2015 (UTC)


 * I've just been watching birds building nests after travelling thousands of miles. Instinct is amazing.    D b f i r s   16:51, 10 May 2015 (UTC)


 * After having travelled thousands of miles I'd be too tired to watch birds build nests. :) μηδείς (talk) 20:41, 10 May 2015 (UTC)


 * Yeah, OK. I also exaggerated.  I should've putten "... birds building their nests after they have travelled hundreds of miles".
 * Neither birds nor words travel well across the Atlantic.    D b f i r s   19:11, 11 May 2015 (UTC)


 * Not just instinct, but also by watching other animals do it. They don't exactly do it behind closed doors. OK, this explanation may not be true for animals that spend all of their days in solitary, such as the cicada, which never sees another adult until it has become an adult itself. Pheromones may also play a big part in this. KägeTorä - (影虎)  ( もしもし！ ) 17:34, 10 May 2015 (UTC)
 * If this wisdom were not innate, a species would not proliferate. "Too dumb to fuck" doesn't have a lot of survival potential. --jpgordon:==( o ) 17:54, 10 May 2015 (UTC)
 * You wouldn't think so, but Bdelloidea forgot (or changed) how (or why) long before we came around. Granted, eternal life as one of those things seems the sort of deal you'd get from wishing on a monkey's paw, but they get by.
 * Though yeah, aquatic life is a whole other ball of wax. Even among the breeders, most don't stick anything anywhere. Some also glow. Best to stick to trying to understand mammals (who do it like they do on The Discovery Channel). InedibleHulk (talk) 00:41, 12 May 2015 (UTC)


 * Young animals don't always get this right; they do practice. Mounting and being mounted feels good even if you don't quite get it right--i.e., good enough to try again.  Otherwise your daffy aunt's shih tzu wouldn't hump your leg. μηδείς (talk) 20:41, 10 May 2015 (UTC)


 * The males do get a little help from things like the estrous cycle, lordosis behaviour...basically sometimes they have an obvious target. Adam Bishop (talk) 08:43, 11 May 2015 (UTC)


 * I can't find a reference just now, but back in the 60s there was a well-circulated news story about how they were trying to get this male gorilla in the Seattle zoo to mate with a female they had brought in. He wouldn't budge, and various ideas were proposed. The most practical solution anyone came up with (don't know if it worked) was to show the ape some "gorilla porn films", to put the idea in his head. ←Baseball Bugs What's up, Doc? carrots→ 17:21, 11 May 2015 (UTC)
 * They still do that with pandas. Of course we should not be surprised that we have a panda pornography article. Adam Bishop (talk) 20:49, 11 May 2015 (UTC)

Stool properties between species
If two species with a relatively similar digestive system ate exactly the same diets, would they both produce very near or identical stools. I am doing research into anarobic digestion and as part of my review this includes a small feasibility study.

So for example, if both I and a hypothetical pet dog both ate exactly the same meal each day for a week, would we both produce the same stool in terms of smell and consistency. Or, maybe a better example would be with another member of the primate family. Chimpanzee? Same result? — Preceding unsigned comment added by 82.178.48.148 (talk) 16:40, 10 May 2015 (UTC)


 * No. Gut bacteria vary considerably, even within one species.    D b f i r s   16:49, 10 May 2015 (UTC)

Cocktails with lime juice
I've just found out that the Finnish juice brand "Juissi" has several flavours of juice containing lime juice. There's lime-lemon, lime-strawberry and lime-kiwi. All contain only fresh fruit juices, water and sugar. No carbon dioxide and no alcohol. Are there any cocktails I could mix with these juices? J I P &#124; Talk 20:02, 10 May 2015 (UTC)
 * This calls for a variant of the Gimlet as well as a strawberry Daiquiri.62.180.109.12 (talk) 20:19, 10 May 2015 (UTC)
 * The margarita is also a classic. The kamikaze also.  The sidecar traditionally has lemon juice, but that lime-lemon mix may be an interesting variation.  A Whiskey sour again has lemon juice, but why not try it.  -- Jayron 32 20:33, 10 May 2015 (UTC)


 * I'm partial to the Moscow_mule - But I'd instead recommend the "Lazy Pony" variant - bourbon, ginger beer, any sort of lime. Your Juissi brand products sound like great mixers in general. SemanticMantis (talk) 13:40, 11 May 2015 (UTC)


 * Here are some general-purpose cocktail tools that are searchable by ingredient . (obviously our taste here is impeccable, but you may want a more exhaustive source :)SemanticMantis (talk) 13:43, 11 May 2015 (UTC)


 * Don't forget the mojito. Marco polo (talk) 19:21, 11 May 2015 (UTC)
 * Ah, the mojito is one my all-time favourite cocktails. And anyway I prefer cocktails with only one alcoholic ingredient. I think I can find rum fairly easily in Alko, although it's going to be very expensive. I have to try to find fresh mint leaves in food stores. I don't know yet, but I'm fairly sure they're easily available, but might be fairly expensive. I just don't know where to find plain sparkling water. If I had a SodaStream machine, I could make it myself, but I don't. Could I substitute plain water or Schweppes Indian Tonic? And for another thing, these Juissi brand juices are green-coloured. I've been accustomed to mojitos being completely transparent. Will this be any issue? J I P  &#124; Talk 21:43, 11 May 2015 (UTC)
 * It would help if you clarify whether you're making these cocktails for personal consumption, for friends in a private setting, or professionally in a bar or similar.
 * If you're making them for yourself, you can mix up whatever the heck you like: if you're making them for friends, you can still do so, but should let them know what you're doing so they don't have false expectations – either way, you might come up with something sufficiently different and new that you can give it a new name. (This is a game played at some Science Fiction conventions, where amongst other things the Spock's Coffin was conceived.)
 * If, however, you're mixing cocktails for paying customers, you should probably stick to standard ingredients, and if you lack some and want to use a substitute, well try it yourself beforehand and determine if it makes a significant difference or not. {The poster formerly known as 87.81.230.195} 212.95.237.92 (talk) 16:21, 12 May 2015 (UTC)
 * I'm mixing the cocktails for myself, not for friends or customers. I know that I could mix whatever I want, but I want the results to turn out good and proper, so I can feel like I'm sipping a professionally made cocktail like in a bar, but far cheaper. So I want to follow the original recipes as well as possible, but not necessarily exactly. J I P  &#124; Talk 18:02, 12 May 2015 (UTC)

plumbing
Why do plumbing stores not sell "3/4 x 3/4" male couplers? I can find 3/4 x 15mm, 22mm, 38mm etc but none sell "3/4 x 3/4". Before someone says it, 22mm is not the same as 3/4. Thanks for your help. — Preceding unsigned comment added by 69.73.46.246 (talk) 23:08, 10 May 2015 (UTC)
 * Hm? -- Jayron 32 00:05, 11 May 2015 (UTC)
 * My fault, should have been clearer. I meant with both ends male threaded. That one only has one end male threaded and couples to something else entirely. 69.73.46.246 (talk) 00:18, 11 May 2015 (UTC)
 * Order some online. Chain stores may not stock them as policy. “Sorry Sir, we don't do them but you can buy a whole 22mm plumbing system from us”. After all, if you can't get this coupling, what’s your option but to replace the whole system. Can you provide a photo? As is possible to sweat a lead/tin joint -negating the need for a coupling. Copper to copper or lead to copper, inches to inches, inches to  millimeters etc., it doesn’t matter. It is a simple sweated joint done with a blow torch. Yet, you should find them online, also  saves the gas on driving around to visit local stores. --Aspro (talk) 00:17, 11 May 2015 (UTC)
 * The problem is I can't find any online either. I've searched and searched and found nothing. For an idea of what I am looking for here is a 15mm x 15mm one. I can find these in 3/4 x 15mm, 3/4 x 22mm, but no 3/4 x 3/4. 69.73.46.246 (talk) 00:19, 11 May 2015 (UTC)


 * That's why I asked if you could provide a photo. I know, that you know what you mean by a "3/4 x 3/4" male coupler but … does it look like this ? 'cause that is a male coupler but maybe not the type your looking for. You image looks like a compression coupling rather than male to male.--Aspro (talk) 00:37, 11 May 2015 (UTC)


 * Sorry that I'm not being clear. I don't know all the technical plumbing terms. Basically, I am looking to connect two washing machine hoses together. Ones like this or this. I gather these are 3/4 female connectors, so a 3/4 x 3/4 male threaded coupler would presumably connect them together? 69.73.46.246 (talk) 00:44, 11 May 2015 (UTC)
 * This looks exactly like what you are looking for. -- Jayron 32 00:48, 11 May 2015 (UTC)


 * And here is another one .Does that answer your question. If not, come back – if does, come back anyway so that we can mark it as solved. P.S. These joints work by compressing them with the little plastic things on the end of the pipes when you screw them together, which is why I said it looked like a compression joint. Now you know.--Aspro (talk) 00:52, 11 May 2015 (UTC)


 * Don't reckon: they're called Compression fittings because they compress a ferrule (or olive, in UK English) in normal use.--Phil Holmes (talk) 17:10, 11 May 2015 (UTC)
 * The seal (in this type of union) is obtained by compression of a nitrile rubber seal. So they are by definition compression joints, because they require compression - just like compression joints that use copper ferrules or olives . So that is  why we needed a photo, to seen just which type of compression joint the OP needed. Once we found out it was for washing machines, we then narrowed  it   down to the application - compression joints for washing machine type pipe-work.  Copper ferrule or olive compression joints are usually reserved for permeant plumbing applications. Copper ferrule or olive compression joints  don't take kindly to being undone and redone multiply times. Every time I have to reconnect a joint with ferrules, I take much care on reassembling it so that it doesn't leak.  Assembling the joint for the first time -no problem-- do it a fews years (even weeks) down the line and it might not seal again-  this situation would be impractical on  washing machine pipe-work.  Hence, different types of compression joints -for different type of applications.--Aspro (talk) 16:06, 12 May 2015 (UTC)


 * I haven't required one for some time, but as far as I'm concerned they do. But if you're having that much trouble you could buy a 22mm Cu compression fitting and remove the nuts and olives. Don't buy Conex brand however as they don't use a BSP thread! Failing that you could purchase a 3/4" black iron or brass nipple (either a barrel nipple or a running nipple) but in all honesty, I'd just buy extra long washing machine hoses.--Ykraps (talk) 08:51, 12 May 2015 (UTC)

Here is a nylon 3/4 x 3/4 connector, if you do not want metal. However this adapter mention adapting a 3/4 inch GHT (Garden Hose Thread) to a 3/4 inch NTP (National Pipe Thread). (Note I linked to the articles.) So I wonder which you have there. Per the articles 3/4 inch GHT has 11.5 TPI (Threads Per Inch) and 3/4 inch NTP has 14 TPI. Also the the article on garden hoses mentions that the female end will have a washer. NTP connector do not need this due to the taper of the threads. By tapered threads is meant the circumference of the threads gets slightly smaller the deeper into the female connector it goes and the male connect tapers (gets smaller) toward the tip. (Remember to to use small font for your phallic jokes.) If you have a GHT female connectors there, the you need to just google "male to male hose connector". (Perhaps small small font.) I found this.
