I usually use a mouse with a scroll wheel to navigate firefox. This is especially useful, as clicking the scroll wheel on a tab closes it, while clicking it on a link opens the link in a new tab. However, I have been unsuccessful at getting this function to work with that button on the laptop that is roughly analogous to the scroll wheel on a mouse (is there a name for that button?). Does anybody know how to implement these features with a laptop mouse, or is this impossible? JianLi 00:23, 13 July 2006 (UTC)
What makes the color red susceptible to fast fadinmg in the sunlight? What is the molecular structure of the red pigment, and how does the sun affect gthat pigment to made the color fade. Does it change the red molecule? If so, what change is made? The red ink printed on paper seems to be very fast in fading -- does this depend on the quality of the ink? The red color in a Polaroid photo seems to resist fading. I've seen street signs on which all of the red has completely faded.
Just what is happening to the red?
What are the symptoms of a person who is anemic?
I'd answer, but I don't have the energy at the moment. StuRat 15:49, 13 July 2006 (UTC)
Signs and symptoms Anemia goes undetected in many people, and symptoms can be vague. Most commonly, people with anemia report a feeling of weakness or fatigue. People with more severe anemia sometimes report shortness of breath. Very severe anemia prompts the body to compensate by markedly increasing cardiac output, leading to palpitations and sweatiness; this process can lead to heart failure in elderly people.
Pallor (pale skin and mucosal linings) is only notable in cases of severe anemia, and is therefore not a reliable sign.

A decrease in blood pressure triggers a barorecptor reflex that leads to increased ventalation. What is the possible advantage of this reflex?-- 69.180.243.11 04:04, 13 July 2006 (UTC)
In India, construction industry is in boom but it is inhibted by low quality and irregular supply. I have done some work on the subject and find that low price is a great price advantage brick has gives it cpmpetitive edge over other substitute products. Increasing demand for agricultural land and general ecological conerns including conservation of sub soil water resources have led to initiation of policies, which seek to restrict use of top soil for non agricultural use. There is also the issue of utilizing ash generated by coal and lignite based thermal power stations in India. In this background there is need for a cost effective technology which has advanatage of low energy consumption, low material consumption, low CO2 emmission and finally and very importantly low initial capital outlay. Can I ask your research and reference to give me access to information on manufacturers of hollow clay block machine munufacturers / suppliers ( new and old.) Any further clarification can be referred to me.

Interstate Brick is a company that manufactures hollow bricks, check the structural bricks section. These bricks have large rectangular holes taken out of them, similar to concrete cinderblocks. Higgins Brick is a company that sells cored bricks, which are bricks with cylindrical holes in them. I wasn't sure which of those you wanted. I found these two companies from the list of clay brick manufacturers at WSCPA manufacturers and I am sure you can find more companies that have the information you need there. Crazywolf 06:01, 13 July 2006 (UTC)
I would say circular holes are best, as they facilitate quicker drying and baking, but don't lead to stress concentrations, which potentially cause fractures, like square holes would. Also, during construction, properly aligned holes can allow for either permanent or temporary poles to be run through the bricks, to hold them in place while the mortar dries. These could also be useful for running wires in a brick wall. StuRat 15:33, 13 July 2006 (UTC)

Hello, does anyone have a link or know of websites which have the map of the whole world in a single image file. There are millions of websites showing maps of regions, but I couldnt find one as per my requirements. And I wish the image file should have large dimensions so that the clarity is also of acceptable limits. Thank You.
Thank you for your links, but i would like to have maps which are "political" in nature, i.e. show the names of all countries, and boundaries.(I think they are called political maps).And the map should be clear, because many maps are there, but they are too cluttered.
Note that a single map of the entire Earth will have major distortions, since the Earth is a sphere, and a sphere can't be flattened into a plane without distortions. This is why a series of maps is typically used instead. Antarctica particularly is messed up badly by most maps of the Earth. StuRat 15:24, 13 July 2006 (UTC)
The industrial float glass process was invented in the 19th century and put to commercial use in the 20th. So far so good. But it would be surprising if the basic idea of floating molten glass on molten metal really was that recent. So when is the float glass principle first known to have been used, or experimented with?

I have had similar thoughts about Acrylamide, which is produced by frying, baking, and roasting. I have been trying to avoid it - a large proprtion of the daily dose comes from coffee. Boiled food or raw food (except olives, prunes, and prune juice) does not contain any. (I think it may be related to the browning of food, and I've been worried if currants, sultanas, raisins have it as I eat these everyday).
By the way, while I think of it, some months ago I added some content to the article on Acrylamide that balanced the complacent attitude of the 'author' (criticised for being so in the discussion). Then I found that the author had removed all my content and covered this up by saying the edit was just about a changed URL. The same author had had his request for promotion to admin status denied as their were suspicious circumstances regarding his nomination. I have avoided looking at the acrylamide article since because I'm too busy to article, and dont want to become involved in a 'war' or be upset by it.

Ohhh dear - this reminds me of a wonderful piece of gibberish by John Clarke about a sports event. it was discovered that the clock at the venue was 20 minutes fast, so rather than starting on time and being 20 minutes early, they decided to start 20 minutes late and be on time.

why does it say "contains sulphites" in all the bottles of red wine i get given at this time of year?? (end of term!!)
The reason is sulphur dioxide may trigger allergic reactions and aggrevate aesthmatic reactions in some people. In the EU this statement is illegal, as ingredients listings in alcoholic beverages are forbidden by law, however many supermarket chains put this information on regardless as a check against people having a reaction and sueing them. It should be noted that sulphur dioxide is a necessary component in the manufacture of quality, stable wine and is allowed in limited amounts even in wines labelled as 'organic' (i.e. without the use of chemicals). This is because it is very difficult to produce wine of any real quality without it. The SO2 is used not as a preservative, as the article on sulphur dioxide states, but as a way of preventing wine from becoming unstable and becoming bacterially infected, losing colour, becoming fizzy, or developing many other faults which would render it unpalatable and unsaleable -- russ 23:42, 13 July 2006 (UTC)
I left some freshly made meatloaf out last night for about four or five hours at 75 F. Is it safe to eat? It's been in the fridge since then. Should I microwave it for a while to make it safer? Would that help much? grendel| khan 23:48, 13 July 2006 (UTC)
When you purchased that meat at your grocers, it was covered in varrious kinds of bacteria. You then cooked it to an internal temperature which (hopefully) killed most, but not all of that bacteria. So what kind of bacteria was it? In ground meat, the biggest bacterial enemy is a certain strain of E. coli, which innoculates the meat when it comes into contact with fecal matter (pretty common) and gets mixed in by the grinding process. So some of that bacteria was left in the meat even after cooking, it's a fact of life. The moment the meat started cooling down, that bacteria started growing again. Now, with bacteria like salmonella sp. and listeria sp., this is not a big deal, because they grow very slowly. escherichia sp., however, grows very rapidly. So in the five hours that the meat sat out, this pathogenic bacteria could have gone through, at most, 30 generations (some strains have 20-minute doubling-times). To put that in perspective, that's 2^30 times as many bacteria as you started with. If you got a meatloaf with just 1000 bacteria in it (a ridiculously low number) and killed 99.9% of it by cooking, you could still have more than a billion bacteria after 30 generations under ideal conditions. Even if you cook that meat again, killing 99.9% of the bacteria in it, you would still have a more than ample pathogenic load to make you sick. I don't think I would eat it. By the way, where did you get 212°? Bacteria (in the real world, there are some that can overcome this temperature barrier, but...) 121°C is sufficient to kill everything (that is the temperature an autoclave reaches). Also, the comments given by the vegetarian above, though undoubtedly in agreement with his or her observations, may be hazardous. Don't leave your meat out overnight (defrost it in the refrigerator), and don't be fooled into thinking that the process of "rotting" or "decay" in meat or milk or any foodstuff is anything other than bacteria in action. (perhaps you were thinking of rancidity Anchoress?). Tuckerekcut 02:24, 14 July 2006 (UTC), MS Microbiology.
Another thing that would help would be to cut off the exposed outer layers. The interior should have had less bacterial exposure. StuRat 02:31, 14 July 2006 (UTC)
The preceeding comment is unfortunately incorrect (sorry StuRat!). The bacteria coming in from outside is inconsequential over this timeframe. The nasty bacteria is already in the meatloaf. Cutting off the outside will not decrease your chances of ingesting pathogenic bacteria. Tuckerekcut 02:48, 14 July 2006 (UTC)
Toss the meatloaf. Remember to refrigerate it next time. Food poisoning can result both from live bacteria and from toxins produced by those bacteria, even if you've killed the bacteria (by cooking) after they've produced the toxin. Meat dishes are often contaminated by Staphylococcus aureus, which produces a heat-stable toxin. Enteropathogenic E. Coli, another frequent contaminent of meat dishes, also produces a heat-stable toxin (as well as various heat-sensitive toxins). In general, if you get sick 4 to 6 hours after eating, it's due to preformed toxin; if you get sick 12 or more hours after eating, it's due to the bacteria proper. - Nunh-huh 08:16, 14 July 2006 (UTC)
I've tossed the meatloaf because, on further consideration, eating it would fail the "emergency room test", meaning that I'd feel real stupid waking up in the ER and explaining that, well, the meatloaf was tasty and some guys on the Wikipedia reference desk said that it might be okay if I reheated it heavily. I find that this keeps me out of all sorts of trouble. grendel| khan 00:12, 15 July 2006 (UTC)

I've been editing a few galaxy articles, and I was wondering if there's some kind of standard: If an event, such as two galaxies passing each other, really happened several million years ago, but due to light travel time, looks like it's happening right now, should it be written in the past tense, or the present tense? Should I propose a standard be created for light travel time? Either way, it should be uniform throughout wikipedia. -- Bmk 21:11, 13 July 2006 (UTC)
Ohhh dear - this reminds me of a wonderful piece of gibberish by John Clarke about a sports event. it was discovered that the clock at the venue was 20 minutes fast, so rather than starting on time and being 20 minutes early, they decided to start 20 minutes late and be on time. Because of that the live radio commentary was replaced by a message saying that, since the event had already finished, live commentary would be transmitted as soon as it hadn't started yet. Grutness... wha? 03:20, 14 July 2006 (UTC)
Please explain string therory in laymen's terms.
Watch the 3 part show "Elegant Universe" or read the book. I found it very accessible and fun!--

why does it say "contains sulphites" in all the bottles of red wine i get given at this time of year?? (end of term!!)
The reason is sulphur dioxide may trigger allergic reactions and aggrevate aesthmatic reactions in some people. In the EU this statement is illegal, as ingredients listings in alcoholic beverages are forbidden by law, however many supermarket chains put this information on regardless as a check against people having a reaction and sueing them. It should be noted that sulphur dioxide is a necessary component in the manufacture of quality, stable wine and is allowed in limited amounts even in wines labelled as 'organic' (i.e. without the use of chemicals). This is because it is very difficult to produce wine of any real quality without it. The SO2 is used not as a preservative, as the article on sulphur dioxide states, but as a way of preventing wine from becoming unstable and becoming bacterially infected, losing colour, becoming fizzy, or developing many other faults which would render it unpalatable and unsaleable -- russ 23:42, 13 July 2006 (UTC)
I left some freshly made meatloaf out last night for about four or five hours at 75 F. Is it safe to eat? It's been in the fridge since then. Should I microwave it for a while to make it safer? Would that help much? grendel| khan 23:48, 13 July 2006 (UTC)
When you purchased that meat at your grocers, it was covered in varrious kinds of bacteria. You then cooked it to an internal temperature which (hopefully) killed most, but not all of that bacteria. So what kind of bacteria was it? In ground meat, the biggest bacterial enemy is a certain strain of E. coli, which innoculates the meat when it comes into contact with fecal matter (pretty common) and gets mixed in by the grinding process. So some of that bacteria was left in the meat even after cooking, it's a fact of life. The moment the meat started cooling down, that bacteria started growing again. Now, with bacteria like salmonella sp. and listeria sp., this is not a big deal, because they grow very slowly. escherichia sp., however, grows very rapidly. So in the five hours that the meat sat out, this pathogenic bacteria could have gone through, at most, 30 generations (some strains have 20-minute doubling-times). To put that in perspective, that's 2^30 times as many bacteria as you started with. If you got a meatloaf with just 1000 bacteria in it (a ridiculously low number) and killed 99.9% of it by cooking, you could still have more than a billion bacteria after 30 generations under ideal conditions. Even if you cook that meat again, killing 99.9% of the bacteria in it, you would still have a more than ample pathogenic load to make you sick. I don't think I would eat it. By the way, where did you get 212°? Bacteria (in the real world, there are some that can overcome this temperature barrier, but...) 121°C is sufficient to kill everything (that is the temperature an autoclave reaches). Also, the comments given by the vegetarian above, though undoubtedly in agreement with his or her observations, may be hazardous. Don't leave your meat out overnight (defrost it in the refrigerator), and don't be fooled into thinking that the process of "rotting" or "decay" in meat or milk or any foodstuff is anything other than bacteria in action. (perhaps you were thinking of rancidity Anchoress?). Tuckerekcut 02:24, 14 July 2006 (UTC), MS Microbiology.
Another thing that would help would be to cut off the exposed outer layers. The interior should have had less bacterial exposure. StuRat 02:31, 14 July 2006 (UTC)
The preceeding comment is unfortunately incorrect (sorry StuRat!). The bacteria coming in from outside is inconsequential over this timeframe. The nasty bacteria is already in the meatloaf. Cutting off the outside will not decrease your chances of ingesting pathogenic bacteria. Tuckerekcut 02:48, 14 July 2006 (UTC)
Toss the meatloaf. Remember to refrigerate it next time. Food poisoning can result both from live bacteria and from toxins produced by those bacteria, even if you've killed the bacteria (by cooking) after they've produced the toxin. Meat dishes are often contaminated by Staphylococcus aureus, which produces a heat-stable toxin. Enteropathogenic E. Coli, another frequent contaminent of meat dishes, also produces a heat-stable toxin (as well as various heat-sensitive toxins). In general, if you get sick 4 to 6 hours after eating, it's due to preformed toxin; if you get sick 12 or more hours after eating, it's due to the bacteria proper. - Nunh-huh 08:16, 14 July 2006 (UTC)
I've tossed the meatloaf because, on further consideration, eating it would fail the "emergency room test", meaning that I'd feel real stupid waking up in the ER and explaining that, well, the meatloaf was tasty and some guys on the Wikipedia reference desk said that it might be okay if I reheated it heavily. I find that this keeps me out of all sorts of trouble. grendel| khan 00:12, 15 July 2006 (UTC)
