i'm getting a job. need the dosh. i'm still gutted over the biochemical engineering exam. if it had been at the same level as the past papers i could have passed it easily but it was i n a completely different league.

My exams for third year finished yesterday. They were also the reason i was banned, SFN was too much of a distraction . Overall i think i did pretty well in Separation Processes 1(diffusion and solid/liquid separation) & 2(Distillation,absorbtion/stripping) and Heat Exchanger Networks. Biochemical Engineering was a complete disaster though, i don't even know if i did enough to pass that one. The whole class feels the same, the exam was nothing like the past papers or any tutorial questions in the notes. some of us even ent through it afterwards with the notes(which sucked ass) and couldn't get anywhere with it. who else is finished/finishing exams now or soon?

instant eh? afraid that would require something below absolute zero. infinitely below. you can however get one thats pretty quick. using a peltier device and a large aircooled(probably with fas) heat sink would probably do the job for you. depending on room temperature the peltier device could be unnecessary though it would significantly decrease the size of the exchanger. also, what sort of flowrate do you need? is it even a flow system?

well, do you have the pressure of the steam? is it superheated or saturated? if super heated, what temperature is it at? is there sub cooling of the condensate? if so, to what temperature do you cool it to? once you know these it is a simple enthalpy balance.

"There is nothing new to be discovered in physics now. All that remains is more and more precise measurement." -Lord Kelvin 1900 he was wrong, this will be wrong. we are still making new discoveries and we will likely carry on making new discoveries.

perhaps they mark out escape hatches?

we know, we just like having a laugh every now and again.

whats the difference? both perform logical functions you can model a brain in a computer(okay, current brain models are that of a fly but we're working on more complex ones as our computers get faster) so why can't a computer develop sentience?

alanejackson, science is a meritocracy, not a democracy. if what you say has scientific merit, it will not be deleted.

It did not contain math because it was qualitative rather than quantitative and not based on physics or chemistry. it did however contain logical deductions. your aether wave hypothesis concerns the physics of the universe and therefore must also be quantitative as well as qualitative. therefore it must contain maths and therefore predictions. these should be falsifiable and if falsified will say your hypothesis is wrong.

iron is only ferromagnetic when it is in a crystaline form. in haemoglobin iit is ionic and bound to active sites. it is no longer ferromagnetic. even its electronshells are no longer that of iron. humans and other animals have been exposed to incredibly strong magnetic fields before(strong enough to pull the iron out of your blood if it were in a ferromagnetic form) and not come off any the worse for wear.

i never seen any glitches. maybe it was because i had the game on low settings to save my ailing computer. it is possible that i mistook a glitch for my computers lack of power.

yeah, red light means stop always. however, there are sometimes filter lanes that will allow you to go(usually has its own green light on the traffic signal, when that is green and you are in the lane, you can go but the other lanes must wait for their green light.

haemoglobin is not attracted by magnets.

probably something on that order.

its been done. it was on tv here in the uk a year or two ago IIRC, can't remember the name.

or a resistor, it'd still be more efficient than that monstrosity.

it'll play halflife2 for sure, my nvidia 5200FX can manage it(just about). i don't know about the biosock demo as my computer just can't do that one. heres a link to one http://www.ebuyer.com/product/127243

well, for one, using the battery to charge the phone directly would be a much better option. the electrolysis and fuel cell are just going to be wasting energy. so much so that you probably wouldn't be able to charge a cell phone with that setup.

if you have agp then you won't have pci-e x16 get a nvidia 7600GT. they are one of the best graphics cards for agp for the price range you are looking at. make absolutely sure you are getting the AGP model as you won't get a pci-e one to fit in on that computer.

Okay, so i was reading the newspaper and seen that gordon brown has decided to reclass cannabis as a class B drug again. He did this against the advice of his scientific advisors. I want to make one point very clear here before people respond: I do NOT care whether you think cannabis should be class A/B/C/legal or whatever, this is about ignoring scientific advisors. now, i thought the whole point of advisors was to tell you how it is. It is obviously impossible for the government leaders(or anybody) to be experts in every field they are likely to make desicions in, so they hire real experts to tell them what should be done and if they are about to make a stupid mistake. what is the point in hiring these people to just ignore them? i don't think voting for gordon is a viable option now as i cannot in good concience vote for someone who ignores evidence and experts and goes along with his/her personal opinions. any thoughts on the situation? any other examples? i only brought up the cannabis one because it is openly known he is ignoring advisors and doing the opposite and that it is recent.

I'm pretty sure if someone put the entire contents of wikipedia into a text file and analysed them in a similar fashion they would also find a 'wikicode' this does not however mean that it was intentional or that any such code exists. language itself is a pattern, if you have a large enough sample then there will always be things in it that look like a pattern. also, patterns can arise out of randomness. take pi for example, the string of numbers is random, but if you look you can see 1234567890 in the string multiple times along with 01010101 and 123123123 and so on. this does not indicate intent, just that randomness occasionally throws something in that kind of looks order but really isn't

or just divide by the crosssectional area in m^2 to get m/s then convert that to miles per hour.

its wrong because E=mc^2 only applies when an object is at rest. a photon at c is quite obviously not at rest. E=mc^2 is a special case of the equation swansont posted, it is only valid when momentum is zero, photons have momentum. to get the right numbers, the mass term has to be zero.

do you have an agp slot or a pci-e x16 slot for graphics?
