very nice collection.

[math]Rate = k[A]^a[ B]^b[/math] is the rate equation for reaction A + B and depending on values of a and b, which will determine the order of reaction, you get various half life equations, for example, for zero-order reaction half life is of one form while for first order reaction is different and so again for third order reaction (cbb latexing you examples here you can look it up on: http://en.wikipedia.org/wiki/Rate_equation ). And as for Arrhenius equation, I believe it is the same k indeed.

imp, are those only your favorite or do you use each often? when i first asked the question i intended it to be a bit more practical, you don't have a nuclear reactor in your backyard do you though if you do let me know i'd like to pull a power cord to my house, electricity bills are ripping it these days... as a general observation so far, everyone has an acid on their list hey YT2095, got any ideas as to where I can find some chromium?

I'm new to Coordination Chemistry but I'm sure you can have less than 18 electrons. If you're unsure as to why this may be the case this section might help you as it specifically addresses that question: http://en.wikipedia.org/wiki/18-Electron_rule#Deviations_from_the_18-electron_rule

to sum it up; i quit. no time to solve this myself and the three people i know from comp science seem not to have the answer so replacement will take place.

great, floppy disk didn't work either. so what now, you suggested ways of fixing/replacing bios without having to throw away the mboard... i'll wait some time to see if anyone else can elaborate on that. thanks for suggestions.

as i thought, flash drive did no good, i'll try to ... TRY to find a floppy disk somewhere...and then tryto find floppy drive for latop.. doubt floppy will help but worth a try.

ah should've known earlier, i never had the problem so i thought it was just in some kind of infinite loop..my bad. i have bios version now on flash disk, i'll try booting with it since i don't have any floppy disks around here! i have a laptop from which im replying now but the keyboard on it is so bad, everysecond spacebar doesntwork... so i use it only in emergencies likethis if this doesnt work then i'll wait to see what that bios flashing thingy is.. what?? how can i buy a new bios? lol as i said, everything else is working as it should, i just dont get that bios beep and no signal output at all... well lets see what happens now.. will report shortly

Ah, another intersting find here; http://www.gigabyte.com.tw/Support/Motherboard/HowToReflashBIOS.aspx just saw it so i'll read through that

hi Dak, thanks for response. I'd rather have to do something than put up another $100 for mboard, though it seems I'll have to anyway. I installed this one 2 yrs ago. Motherboard is Gigabyte 7VM400AM-RZ, some cheap model http://www.gigabyte.com.tw/Products/Motherboard/Products_Overview.aspx?ProductID=1849&ModelName=7VM400AM-RZ I'll try to find the bios upgrade/fix or whatever and see how it goes... and I don't have lot of time to research as I have 3 things due in this week each worth 10% and now I have to fix my pc first! so whatever I came up with in the next day or two I'll try, then throw the thing in the bin. and one more thing; http://www.gigabyte.com.tw/Support/Motherboard/BIOS_Model.aspx?ProductID=1849 would you know how exactly am i supposed to install this bios? because website says; "Please remember to "Load Optimize Defaults" (in the BIOS Setup) after updating new BIOS" and I can't even get into anything at all... no signal is coming to monitor. edit:ah i see it says "after updating to new BIOS" so i'll try that first ..

hi all, i have an interesting one here... turned my pc on today like every other day and observed a really weird series of events, unlike anything seen before; first the computer started continuously restarting after which it stopped and a message came up saying something like "scanning hard drive for BIOS image" and below that another message "BIOS auto recovery" and a series of dots that were supposed to be some kind of progress bar I think...then it restarted again and so a few time like that until at once the entire screen was full of those dots and it appeared to be going on forever with last line of dots on the screen moving like a progress bar from left to right, it kept doing this for a few minutes until i switched it off... left it off for 15ish seconds and then back on and the only msg i saw was the blue on screen msg from monitor saying "no signal". green cpu led is on, cpu is hence on, so is graphics card and i can hear the harddrive on as well... but nothing is happening... so far the only thing i tried was to take out the battery from bios, while it was out i quickly checked voltage, it wasn't empty at all so im sure its not battery, put it back in (in hope that this would've reset the bios?) , restarted pc and again nothing. any ideas?? i have a feeling something burned up in the bios

Was it determined at what speed this planet rotates on its own axis? In either case, would this have any implications on possibility or sustainability of life? My guess would be 'not much' but just curious.

Maybe some of these questions would hint at things; You tried this with latest versions of firefox? Is everything ok with cookies? Do you have software firewall and are its options set out properly? Is your router's firewall set out correctly, perhaps you or someone else blocked an ip range accidentally? I mean, if you get same thing from two different computers on the same network, and you're sure these computers aren't clones of each other (disk images), then it's obviously something up with router or ISP, as far as I can see... It's likely there is an ip range blocked at some point, might pay to check, but if it's not then try this; connect one of the PC's to the internet directly through the modem and see what happens. Did you try resetting the router, or your server, through wherever the internet is coming? If none of that works out then it's probably ISP. Try asking someone on the same ISP to access the sites at the times you can't.

I think amino acids are responsible for most of the things happening in biological systems, but not all. Of that one though, I'm myself unsure

hmmm see if I've answered your question yet

There are others yes but there is a 'main' or standard group of 20 of them that are found in proteins - hence biological systems. There are a few nonstandard ones also found in proteins but are generally rare. Now I understand what you're asking. Well, if you go 'down' zooming in close enough you're eventually going to see only atoms, but if you're looking for amino acids I think you won't find them at all parts of a biological system. See a bone for example, there are calcium salts which aren't amino acids. Maybe there are other examples, I'm not sure.

Not sure if I understand what you're asking but here's a brief explanation. Amino acids (20 of them) bind together to form peptides, simplest being that of 2 amino acids - a dipeptide. When you have very long chains of amino acids they are called polypeptides. Proteins are really chains of these very long polypeptides (from 100 to many thousands of amino acid residues make up a protein). Enzymes are really proteins, they are one type of protein. Other types of proteins include hormones, antibodies, toxins and others. I think these are referred to as roles of proteins rather than types of proteins but unsure, the main point is that they're all proteins. Proteins are found in all biological systems so therefore amino acids are found in all biological systems.

Awesome. Well it's the only thing I've got available so I'll try to work it out. I might buy one of those cooking torches since they're not too expensive but I'll first check if they'll let me use uni's lab - which I doubt, but remain hopeful. Thanks YT, I'll report again when I make progress

Ah ok. I'm not entirely sure if it's borosilicate. Actually this is the one can you tell me what it is? http://cgi.ebay.com/SIMIX-12-MIL-PYREX-TYPE-GLASS-TUBING-24-24-feet_W0QQitemZ250101770739QQihZ015QQcategoryZ11812QQrdZ1QQcmdZViewItem The seller claims its easily workable with propane torch...

I received my glass tubing today, 4 tubes around 50cm each, but I can't seem to be able to bend a piece as required using the best heat source I have available at home - gas stove. I'm assuming it can't provide the necessary temperature? As I haven't had any experience with glassworks, is there a method to this? Is the borosilicate glass supposed to turn 'orange hot' for me to be able to bend it? I don't think I'm in the mood to buy propane torch right now, so just a question, will I be able to do what I want using Bunsen burner at uni lab?

awesome! thanks for sharing!

Plastic setup was just an example (anything cheap and easy to work with would do), but the reason to have something simple to work with is so that landscape can be shaped into many different forms rather than to have the entire setup moved from one old builidng to another (the reason being is that it would be easier to reshape the platform than to move the entire system from one location to another). Of course, using real grass or rock for example, or trees, would result in a much nicer and better virtual animation. (example: if you walk over a hill and you need to lay down, if it was plastic without grass on top of it you would feel the actual plastic and see the grassland instead (through the goggles)). But then again, if you used real rocks for the platform that could result in people getting hurt! Perhaps some real stuff could be used, like grass or trees, but rocks or big holes in the ground should be avoided! Laser measuring devices can be used to get precise detail of landscape required to assemble and some other system to capture all the textures to a fine detail (for this even simple photography would do). The detection system is probably patent-pending as I can't clearly devise anything in my head now, however I'm pretty sure that it can be worked out somehow. One way would be to use the same kind of sensors that are placed on motion lab suits and that way every object would have known position (rotation and elevation) within the 3D framework (the accuracy of which would depend on the number of sensors that are placed on the object). Other ways would be to use direct visual detection, which would probably be harder or perhaps even unfeasible... 'Metal objects' was also an example, there is no need to detect anything metallic if the motion sensors are operating fine, but since I'm not completely familiar how motion sensors work I can't say anything more about it apart from that it could work. If you see any other problems please feel free to point them out as I'd like to know. I would really like to try and make this happen, at least on a small scale, for I'm pretty sure I'd be able to eventually work it out. I guess the next thing for me would be to research the motion sensors.. and I will when I get time But seeing how nicely it works in motion labs I'm pretty sure it can be engineered to work for this VR system. The best thing of all though is that you don't have to imagine anything when you play (unlike with the today's top-tech games like LaserQuest or Paintball where the only fun is in the actual chasing and fighting... ). What I want is to be able to "inject" myself into the action, think of it much like entering the game. What you used your mouse and keyboard for when you played 3D games on your PC has now been realized into the actual movement - you want to move forward - you simply walk forward!, you want to jump - you jump!, you wan't to fire a gun - you take a gun and fire! The difference between that and say, a game of paintball, is that here you will be able to see planes flying above, perhaps even dropping bombs, you will be able to see exposions happening few meters away from you with pieces of dirt or snow flying around and the sound from the speakers in the ground or on the walls, you'll be able to see different weather conditions, you'll be able to shoot at people and see them fall (not saying that's a nice thing to do but considering that you aren't hurting anyone for real it can be considered as fun) and so on... I think that this system will eventually be made, some time in the next decade or so, perhaps sooner, but if it doesn't I'll do something about it

Suits like that would need to be very advanced, probably far more advanced than the suit I described in my 'idea'. I've seen only internet-based handshake device based on that idea, where two people can handshake by having 2 robotic hands on each end. When you move your hand in the robotic glove it automatically moves the other one on the other end, hence handshake possible

For many computer or real-life games you tend to forget that it's just a game, but that's only because you're new to the experience or enjoy playing it very much. However after a while the experience changes with any game. By " a while" I mean at least 150-200hrs. I've played around 950hrs of Call of Duty last year online (program counted it) and although that may seem like a 'sick' amount of time to spend playing games to a non-gamer, it can't even be compared to a LOT of people who spend that much time playing World of Warcraft for example in only 3 months or so. When you play a game that long you either get very tired if the game is bad or you just want something more out of it if the game is good. With Call of Duty, as I described, I'd be the first customer to play it in VR World because no Paintball or LaserQuest or anything else can recreate the environment and the era. True you can go to war for real but that can end up deadly, besides WW2 can't be compared to any wars of today. As for adventure games, that's a good point too. It could be fun in VR World but it can simply be better if you go out venturing for real. Unless you want to create a game with monsters and such, which would also be pretty damn cool, probably more adrenaline-packed than WW2 simulation. It's just that I picked WW2 sim since it's my favorite genre and simulations on computer screens can't be fun all the time.

LaserQuest is interesting, I'd like to try it once. However the system I visualized is much more advanced than LaserQuest. I'm not saying it doesn't have limitations itself but if made into a prototype I would certainly be very very excited to see it.
