I don't understand constants, the control, independent and dependent varibles. Or what role do they play in a science fair project? Please explain. Thank You. Molly Smith

I'm working on an anaerobic digester design and i found that the CH4:CO2 ratio is between 1:1 and 3:2. In addition it may contain Hydrogen Sulphide, Nitrogen, Amonia and Hydrogen in small amounts.
I'm planning to utilize this gas to produce CO2 to be used in another industry. So i would like to know further information about following issues.
1. will it be effective to combust methane+CO2+other trace gasses mixture to produce CO2
(will the excess CO2 affect the complete combustion?)
2. What will be the products after combustion of the above gas mixture?
3. what will happen to NH3 and H2S after combustion?
It is planned to combust the mixture in lower temperature (Less than 200 C)
Appreciate any suggestion to success my effort and any links regarding this process will be really helpful to me...!! Thank you.

What's the worst snake to be bitten by ?
I have heard that many deaths due to snake bites are mainly due to fear and panic rather than the poison itself !. -- Wikicheng 06:54, 17 October 2006 (UTC)
This question might be a bit long-winded, but, here goes. Hyperthetically, imagine a very young, 'borderline' Black Hole: A supernova 'just' went-off and produced said black hole. By 'borderline', I mean that had the original "sun" been JUST A BIT less massive, it would have produced a neutron star instead. Now, would it be possible to FORCE-FEED this black hole with enough matter to change it into a neutron star? For that to happen, would the matter have to be "fed" at faster than the speed of light? (of cousre impossible, hence, hyperthetical). Once a black hole, ALWAYS a black hole? (ignoring evaporation). Just something to 'chew' on. Thanks, Dave 152.163.100.74 06:55, 17 October 2006 (UTC)
No I don`t Mac Davis. Perhaps I should have posed my question thusly: Can a black hole, or even a neutron star, for that matter, be 'force-fed' to return to main-sequence 'status'? Touche about Stephen, Light! 8)Dave 152.163.100.74 14:29, 17 October 2006 (UTC)
Is there a set amount of water in the world? I understand the process of condensation and all that but I wonder, if it's always a circular movement, then is there a certain amount of water thats continually moving around or is water created and destroyed in some way, if so, how?
Thank You
A huge amount of water gets entrained in subduction zones. There is actually a geologic water (and carbon) cycle, which can be tracked in geologic time. The amount of water in the biosphere varies over millions of years. -- Zeizmic 11:58, 17 October 2006 (UTC)
So, to answer the question, yes, there is more or less a constant amount of water on Earth. While it can be created or broken back down to hydrogen and oxygen, these processes are more or less in equilibrium, so there is no net increase or decrease over time. StuRat 14:21, 17 October 2006 (UTC)
Burning (or almost any other process in the troposphere) will have a negligible effect. There are however geological effects that sequeater water by reacting it with magmea to from other kinds of rock. In the very long term, this water will be recycled into he troposphere. Thare is a larger effect in the upper atmosphere. Sunlight "cracks" water into hydrogen and oxygen,and the hydrogen escapes into space relatively more easily than does oxygen.

It is oftern said that the most poisonous animals live in Australia. Our articles on venoms, i.e., animal poisons, seem to agree with that and also list quite some dangerous animals in South America. Here, in Europe, is is nearly impossible to meet animals with deadly venom, and also African and Asian animals seem to have a rather hard time killing a human. This looks to me as if the human body is well adapted to deal with the kind of poisonous animals to which the species Homo sapiens was exposed during the longest time of its evolution, which happened, as we know, mainly in Northern Africa and then spread out from there, South America being populated rather late and Australia very late. So, do you think that we humans have evolved the immunitary capability to deal with Old World venoms and hence, New World venoms are more dangerous? A counter argument would be if other large mammals were also more easily killed by, say, Australian snake species than be European ones, even if they are marsupials that evolved in Australia. Does anybody happen to know about this stuff? Simon A. 11:51, 17 October 2006 (UTC)
Can anyone please give me information regarding end correction in resonating air columns ? I would like to know what causes it and how it can be calculated . Thanking You.
Microwaves, as i have heard can impart heat and momentum to air molecules, much like what happens in a shockwave during an explosion. The air is propelled into objects and as it is traveling it is heated up and expands causing even more pressure against what it hits. Does anyone know what frequency microwaves would be needed to create the same effect without useing chemical explosives? Is such a thing possible?
Robin
Is there any kind of EM wave which could impart enough momentum to air to cause a shockwave, or heat air up enough, causing it to expand quickly causeing a shockwave? Robin
How do I add a link from an existing wikipedia article to a search list?

I ran for 20 minutes today at a slow pace. I guessed it to be about 4 miles per hour, but it could have been a bit faster. I weigh about 12 stone (168 pounds or 76 kilograms). Some questions:
a) How fast is a slow jog considered to be?
b) How many calories did I burn?
c) What is considered normal walking speed?
If I knew c) then I could work out how fast I run and then measure how far I've gone and my calorie consumption. Cheers!
"Jog" means to "run slow" in the first place. 4mph would qualify as jogging rather than running, and since it is quite easy to walk 4mph, you could classify it as a slow jog. People walk at different speeds, but 2 to 4 mph would be normal. - THB 22:22, 17 October 2006 (UTC)

Im looking for an easy and peaceful way out. i dont have the guts to throw myself off a bridge or anything like that. i was thinking about overdosing on over-the-counter drugs but im afraid that would cause slow and painful death or just make me realy sick. where can i obtain a suicide pill (doesn't have to be specifically made for that). i need something that would do it painlessly and easy to obtain (in Canada) or buy online.
p.s. please dont point me to suicide prevention bullshit cause those people are just stupid. my problem wont ever go away and im going to end this. its just a matter of how.. i dont want to have to run in front of a bus or something.
Unfortunately, an overdose can screw up and leave you brain-damaged or in a coma. It would be interesting to know what is so irrevocable and permanent and it would help answer your questions. - THB 22:12, 17 October 2006 (UTC)
There is another way to leave your problems behind, just get up and leave. Go somewhere where nobody knows you, your past, or your problems, and start life over. Of course, this doesn't apply if your problem is a terminal disease, but applies to just about anything else. You might say you would feel guilty about leaving everyone you know, but you would be doing that anyway if you killed yourself. You can either tell people you are leaving or just skip out of town, your choice. StuRat 00:06, 18 October 2006 (UTC)
The loss of you would greatly diminish each of us. Everyone I know has had times when it didn't seem like life was worth living: your loved one is gone, or the job is lost, the stress is too great, or the health is impaired. But we have found that as time went by, other things came along which made life worth living. Don't give up. Medication can help you get out of the biochemical pit of depression. ""All mankind is of one author, and is one volume; when one man dies, one chapter is not torn out of the book, but translated into a better language; and every chapter must be so translated...As therefore the bell that rings to a sermon, calls not upon the preacher only, but upon the congregation to come: so this bell calls us all: but how much more me, who am brought so near the door by this sickness....No man is an island, entire of itself...any man's death diminishes me, because I am involved in mankind; and therefore never send to know for whom the bell tolls; it tolls for thee." John Donne. Edison 05:39, 18 October 2006 (UTC)
@anon who posted death notice: Death is something like...KFCd. The advertisements of it are present in movies, TV programs, and books. It looks so tempting and it looks if it is the only solution to problems. But hey, there's healthy food. There's water instead of the drink of death - Coke (sorry Coca Cola company) And if you presist to have those wholesome things in life instead of KFC/suicide, you will eventually look back and say: "Hey, WTH was I thinking! KFC fried chicken contains 10000kJ!~" ;) Hope you decide to stay. -- inky 07:57, 20 October 2006 (UTC)
You can try using painkillers or antidepressants. But whatever drug you decide to use, make sure to swallow as much as you possibly can. You may think "oh, I've taken ten times the normal amount, that should be enough to kill me", but if it doesn't, it will be very painful.
I know that many people who are dissuading this question's poster from suiciding are doing so in good faith. However, I also know that the poster has thought of everything you've said. The only way his mind is going to change is if things improve for him. If things don't improve, letting him suicide is the only humane option. -- Bowlhover 02:19, 23 October 2006 (UTC)
While some bacteria are harmful, most bacteria serve a beneficial purpose. Higher lifeforms would not exist on earth without the presence of helper bacteria. Viruses on the other hand seem to be, at best, innocuous and, at worst, highly destructive. What biological purpose do viruses serve (other than killing off the weak)? Are there any "good" viruses?
Viruses move genes around and thus provide a source of diversity to then be acted upon by selection; ie they speed up evolution. However the words 'good' or 'bad' do not apply. -- GangofOne 20:59, 17 October 2006 (UTC)
Some viruses are desirable: Good Viruses - THB 22:09, 17 October 2006 (UTC)
In the future, we may be able to change our genetic codes using a virus to deliver the new DNA. This is obviously quite dangerous, but could be enormously beneficial, as well. StuRat 23:54, 17 October 2006 (UTC)
"they speed up evolution. However the words 'good' or 'bad' do not apply" <-- The term "good" is used here in the context of what is beneficial for virus-infected organisms. Theoretical biologists such as Stuart Kauffman have discussed the importance of evolvability as a trait. In addition to playing an important role in the rate of evolution, some hypotheses suggest that viruses played a fundamental role in the origin of cellular life as we know it; see: Three RNA cells for ribosomal lineages and three DNA viruses to replicate their genomes: A hypothesis for the origin of cellular domain by Patrick Forterre. -- JWSchmidt 01:51, 18 October 2006 (UTC)

Lets all be honest here. The guy asked you not to try and chage his life. Leave him alone. He obviously has issues that we could all never relate to, so be it. Let him die. Its of a waste of your time trying to fight for him. Thats one less person in the wrold to clean up after and lets hope his repalcement has a positive out look on life. Serisouly if I was you, i'd pump myself up on drugs and shoot myself in the head.At least before I die, the world will look a but prettier.

I'm wondering if someone I know smokes it. The smoke is somewhere between the smell of tobaco smoke and incense sticks. I'm not going to turn her over to the cops, just curious.
I think she would be very unlikely to smoke any kind of scented cigarette, clove cigarette, or bidi. I don't want to ask her as she would think I was being hostile. Does cannabis smell unpleasant, or pleasant? What exactly is meant by it smelling "pungent" for example?
It has been described as the smell of burning leaves. Expensive pot, like the smell of expensive burning leaves. Edison 05:43, 18 October 2006 (UTC)
I heard something on this before, but am still not sure so shall just ask directly and to the point, Em waves can cause momentum transfer with air molecules right? so that means that it is , at least in theory , possible to create EM wind, that is, air currents caused by interactions with Em waves. Is this correct?
So of this is possible then a EM caused overpressure shockwave would be possible as well if the air could be accelerated to supersonic speeds right? Robin
They actually already have a laser which does this its called pulsed impulse laser, its on wikipedia, they wanna use it for crowd control, but i think this combusts air which propells air around it rather than adding momentum to it or causing air to heat then expand propelling air around it like an explosion, it actually causes an explosion rather than just the shockwave.
Helping with a forth grade report and have had problems finding the run donw from kigdom to species. Kingdom, phylum, class, order, family, genus, species, common name? I would appreciate any help.
I own a 5 year old thoroughbred mare who is presently in training for horse racing. At home she behaves well and even though she had an older mare in the next paddock does not come into season. However as soon she is placed in a professional training environment with other horses, particularly indoors, she immediately comes into season and begins behaving very badly. We have tried deprovera injections without success. I have heard that implanting a glass marble in the uterus can help. Does anyone out there have any knowledge of this problem and possible remedies?
Your help would be appreciated.

Tony

I heard something on this before, but am still not sure so shall just ask directly and to the point, Em waves can cause momentum transfer with air molecules right? so that means that it is , at least in theory , possible to create EM wind, that is, air currents caused by interactions with Em waves. Is this correct?
So of this is possible then a EM caused overpressure shockwave would be possible as well if the air could be accelerated to supersonic speeds right? Robin
They actually already have a laser which does this its called pulsed impulse laser, its on wikipedia, they wanna use it for crowd control, but i think this combusts air which propells air around it rather than adding momentum to it or causing air to heat then expand propelling air around it like an explosion, it actually causes an explosion rather than just the shockwave.
Helping with a forth grade report and have had problems finding the run donw from kigdom to species. Kingdom, phylum, class, order, family, genus, species, common name? I would appreciate any help.
I own a 5 year old thoroughbred mare who is presently in training for horse racing. At home she behaves well and even though she had an older mare in the next paddock does not come into season. However as soon she is placed in a professional training environment with other horses, particularly indoors, she immediately comes into season and begins behaving very badly. We have tried deprovera injections without success. I have heard that implanting a glass marble in the uterus can help. Does anyone out there have any knowledge of this problem and possible remedies?
Your help would be appreciated.
Regards
Tony

Sorry about the apparent name change. I am a first time user and just learnt how to sign my user name (which, by the way, is the racing name of the horse). Regards Tony. Mumzwon 03:09, 18 October 2006 (UTC)
