I want to do my M.S in automobile engineering.What is the best place in world to do it i.e institute?What is it's admission procedure? —The preceding unsigned comment was added by 210.212.215.141 ( talk) 06:01, 23 April 2007 (UTC).

I heard running 1 min on the treadmill and then walking 1 min, running 1min again, and walking over and over again is better than running strait, is this true? —The preceding unsigned comment was added by 76.167.136.84 ( talk) 06:15, 23 April 2007 (UTC).
From what I understand, when blood sugar gets low, you get hungry, and when you have carbs, it goes up again and your not hungry anymore. So how are you not hungry if you only have protein and lets say salad? If theres no carbs, or very very little, how does your blood sugar rise? How are you no longer hungry? —The preceding unsigned comment was added by 76.167.136.84 ( talk) 06:17, 23 April 2007 (UTC).
I was losing weight for a while on a reduced calorie diet (1200 calories a day, I'm a male, 180Pounds from 200 before) and weight training and cardio. Now I'm not losing weight anymore, and I can't figure out why. I tried changing my procedure (from elliptical to uphill walking on the treadmill) and its still not working. I usually do an hour of cardio 5 or 6 days a week. Is it too much to do 2 hours a day? Any other suggestions on what I can do? Thanks
It might be possible :) I gained an average of almost 2 pounds a week for a few months and probably did a lot less work than you are, and I tend not to eat much protein either :) HS7 13:09, 24 April 2007 (UTC)

The human body will tolerate maybe a tablespoon of salt and maybe forty-three cups of coffee. Is there and limit to how much sugar the human body can handle before it does something expected or strange? 71.100.8.252 08:53, 23 April 2007 (UTC)
The LD50 for suggar is about 30g/kg Rat, upscaling to a human is 2-3kg for a human of 80kg. -- Stone 10:17, 23 April 2007 (UTC)
I am a program assistant with the Kadena Air Base School Age program on Okinawa Japan. I have been trying to find ocean current maps that we can track tropical storms and typhoons. I would appreciate any suggestions you might could give me on where I could download or acquire these maps at a minimal cost. Our program runs on tight budget. I think the children would really like to be able to track these storms and see which ones might affect our island. Thank you so much for your time and I look forward to hearing from you.

Dear sirs,
I have made a high pressure boosting system for carbondioxide gas using gas booster, with various valves in loop. The system is able to boost the pressure to 350 bar with the needle valve in closed condition at the outlet of the system, but as soon as the needle valve is opened, to let the gas flow to an extruder barrel, the pressure drops, and then does not boost, unless the valve is again closed. Please advise in the matter, that is there any device which will assure me consitent flow output with high pressure.

what is the term where atoms of same element have same mass number but different atomic number?
are you talking perchance of moles?
The other day I got out a meal to microwave then accidentally put the microwave on without putting the food in it. I've always been told that this is something you should never do: even if you are testing the microwave you should put a glass of water in it or something. What is the consequence of leaving a microwave on without anything in it? —The preceding unsigned comment was added by TomPhil ( talk • contribs) 14:57, 23 April 2007 (UTC).
(edit conflict) take it from someone that has acctually done this out of courosity. Dont do it! i almost burnt the house down from this experiment and well basicly the bottom heats up. if its one of those rotating micros, the thing that rotates tends to be the thing to catch fire first. well like i said just dont do it, its not worth the risk.

I noticed the actual largest thing in the universe was found last July [2] , but I can't seem to find a name for it. It's 200 million lightyears across and 12 billion lightyears away, but googling isn't helping me find a name for it, and it doesn't seem to be mentioned in 1 E+24 m, 1 E+25 m, or 1 E+26 m.

when do christmas trees die? they appear to be alive when you buy them, as you still need to feed them water, but they are ultimately dead once they are cut off from the roots? so technically, when do they officially die? —The preceding unsigned comment was added by 128.175.20.122 ( talk) 15:15, 23 April 2007 (UTC).
Suppose I have a budgie in a cage (or a seagull; it doesn't really matter) hanging from a spring scale, and I scare the bird so that it takes flight (without hitting any other part of the cage), would the force measured by the scale change? Furthermore, would it matter if the cage was airtight (ignoring the fact that the bird would suffocate!), so that all the air being displaced by the bird's wings remains in the cage? Laïka 16:01, 23 April 2007 (UTC)
flight uses up energy, which would lead to the break down of glucose into water and carbon dioxide, and the loss of carbon dioxide, unless the cage is airtight. But really this is very much oversimplified. If the bird was flying continuuosly for a while, it might lose a small amount of weight in this way, almost enough to be measured.
My schoolmate asked physics teacher if ferrofluid applied to refrigerator would stick or would it fall down. The teacher didn't know, but it made me curious - can ferrofluid be used fridge magnet ? ---- Xil/ talk 18:02, 23 April 2007 (UTC)
hey, today *out of all the days lol* i was just wondering. what are the chances that science will grant us the technology to live an additional 300 years; *assuming it can be done* with like stemcell or whatever other means. and will this be possable sometime during my lifetime or is this kind of technology far away?. Lets not forget affordable. if this tech does come in my lifetime will it be afordable lets say a middle or lower class person? thanks for yout time User:Maverick423 If It Looks Good Nuke It 18:13, 23 April 2007 (UTC)
Since this question calls for an opinion, I've answered here: [3]. StuRat 19:06, 23 April 2007 (UTC)
and the second way is..?
Yea this one is one of the best i heard. merging ourselfs to computers, but it would worry me. computer viruses tend to corrupt and delete data, entrusting our memories , or even becomeing part of a computer, might cause more damage. but then again we can always have back up memory drives and stuff. Also mattb make sure those numbers are for the megamillion and dont forget the bonus ball =) User:Maverick423 If It Looks Good Nuke It 19:34, 23 April 2007 (UTC)
well what i was thinking is that maybe stemcell research can help us live longer. if ur heart starts to fail get a new one with stemcell. since its made from you your body should not reject it. the same with all other parts of your body. i also heard stemcell might be the awnser for other desiese (got i was never able to spell that word) like alzhimers or even the nervous system. for the skin there is that botox thing heh User:Maverick423 If It Looks Good Nuke It 02:27, 24 April 2007 (UTC)
Even if we could survive every possible 'accident' and cure all diseases, there is still a major problem with living for a long time :( All human DNA contains telomeres at the end of each cromosome, which have no effect on people's genes, but every time the DNA is replicated, a small part of the telomere is lost, so that eventually there is none left and the cell can not divide any more :( So the only way of living in a human body for a very long time would be to find a way to either add more telomeres or replicate DNA without losing a bit each time :( HS7 12:57, 24 April 2007 (UTC)
So where do new telomeres in children come from, as they have the same DNA as their parents?
And does this mean there is always one cell in every animal with the full lenght of telomeres?
The main difficulty with this is geting the DNA sequence inside the cell, inside the nucleus and then attatching it to the ends of every chromosome:( Food only gets into cells once it has been broken down and either disolved in water or passed through protein channels, which can only move small chemicals, with a telomere probably not counting as small:( But they are arranging ways of putting DNA on bits of metal and fireing it into cells :) And they can only do this with one cell at a time, not the hundreds of millions people would need fixing if this was to be viable :( HS7 20:28, 24 April 2007 (UTC)
Does anyone recognise the species of the duck in the picture? I saw it in the Netherlands (outside the parliament buildings) and thought it was very pretty. The only ducks I have ever seen are Mallards, and these were significantly larger.
