Re: Plastic Vs Aluminium
And making additions to that extruded PTFE would be for what reason? As an actual *materials* engineer, not the idiot mechanical engineers we spend all day fixing the screwups of and who are responsible for this 'PTFE is too brittle' nonsense, PTFE extruded insulation is used because of its fireretardence and excellent environmental and electrical performance. PTFE does exist as a *bulk* engineering polymer with lots of different additions, but no-one on earth is going to try to extrude Glacier DU around a gorram piece of nickel-plated copper wire. The reference in WIki is bunk. PTFE has a continuous upper working temperature of about 150 degrees. That's continuous as in, forever.
And, really? Brininging kapton into the conversation to muddy the waters? Kapton is polyimide, a thermosetting polymer not a thermoplastic, with entirely different set of chemical mechanical and environmental properties for PTFE. This is nothing like the issues with kapton insulation, thank you very much.
*Seethes at the general ignorance*
Re: Won't be told
Please RTFR, lithium manganese dioxide batteries are worlds away from lithium ion and lithium polymer batteries...
So what the author is suggesting is...
Re: 10,000 tons
And it would have to be basically cubic to get anywhere *near* ten thousand tons. It's not sideritic, it's rocky, so it's approximate specific gravity would be a bit over *2*.
Looks like particularly lazy maths. And that's not a novelty, comign from NASA.
Re: Not actually fussed about Gib either way but...
You're welcome. *Clicks*
Staff purchase equipment that actually meets their needs and it costs more than the old tat corporate IT departments dumped on them, when ten years ago, it was five years out of date. Whodathunkit?
Re: Deep breath...
What asshole downvoted this?
I'm sick to the back teeth of the Hanlon's Razor Nuremberg Defence. "They were only being lazy and stupid."
Ignorance and willful stupidity *are* malice. If you can't be f***ed to learn and you can't be f***ed to understand, that's f***ing malice aforethought. Just 'cause it seems more fuzzy and friendly than outright hostility, it's as antisocial as ti comes nonetheless.
When they build a 400 seater bus...
...Then the comparison will be apt.
What a bunch of eh-holes.
Pull the other one, DOJ
It's got bells and whistles on
(Can we have a Bastille Day like icon, please?)
And why do they never release the actual numbers? The last actually released mechanical property figures slipped drastically below the strength of steels above 2*mm* in length. Making them in visible quantities hasn't been a problem for years, the issue lies not with their 'difficult to work with' nature, but their utter sensitivity to thermal vacancy defects, defects that they *cannot* be made without and increase statisticallty with the temperature of manufacture. It is these defects that limit strength and the bigger you make them, the higher the probability of defetcs existing in the structure, a structure that requires perfection to achieve these magnificent strengths.
I'm not saying that the theoretical strength of these materials isn't incredible, but the thing about materials science is not what you hope it will achieve, but what thermodynamics lets you achieve.
I notice that no-one talks very much abotu the explosive strain energy contained in the structure, either. The propogation rate of energy release in these things at failure is about 50% higher than an equivalent mass of *TNT* :-D
There's an 'infomercial' shown, certainly in Cineworld Cinemas around the country that displays in typical cringeworthy 'comedic' style this behaviour to prevent mobile telephones runing movies. YOU'RE NOT MEANT TO USE IT AS AN INSTRUCTIONAL, YOU ASSHOLES.
Alfheim, Jotunheim, Asgard...
Well, it all began about nine million years ago...
It's strange... that all the fish with high metabolic rates tend to be bloody huge. Tuna, Mackerel sharks, that sort of thing. Odd that peopl estudying fish missed that one.
Is the shrinking size of fish suppers now not more to do with overfishing that means younger and younger fish are dragged from the ocean, before their prime?
And to think, I'm so tired of this ass-poor correlation automatically equalling causation mentality, that I was actually expecting their assertion to be that higher temperatures lead to lower solubility of oxygen in water, per se, in line with the general dissolution of gas in liquids. Someone might want to call the Devonian period and ask about how small the Dunkleosteus were then...
I'd be more inlined to consider the polymeric seals as a leak path...
Re: @adam payne
Wow - what insight. When there's essentially only one reason for a course of unpopular and counterproductive action, who would there be anything but manifold references to it?
Oh, the old two-party works, screw activists mentality, eh?
I was going to comment on the naiveity of some of our ACs and their desperation to get their irrelevant twopenn'orth in, but meh.
Re: It's the year 2020...
And thanks to EC/197/2006, there'll be no useable engineering materials nor chemicals to make anything with at all.
Re: No shock here
Not true. There are a chunk of DX10 components available through winetricks, d3dx10 springing to mind, and a number of dx11 bits being considered.
Even purely dx9 games feel smoother.
No shock here
Something I've empirically seen for yonks. Running most DX9-DX10 titles through WINE gives me better performance than on the Win 7 install I had before, and that's with another abstraction layer in the way, courtesy of Moroccan Tea :-)
Admittedly, my machine is more a lower end gaming rig by design anyways... 6950 GPU , 4-disk RAID 5 PRIMARY, 8GB of Corsair 1600 DDR3 and a 945 CPU. I'm not sure i fthat's statistically valid but meh...
The plural of ninja is ninja :-p
Lego is made from ABS, so about 140 degrees maximum service temperature.
It's moulded at about 240 degrees.
No recordings of it before you say?
Go speak to the Foxs. Their life's work is a scrapbook of sharks. They've lived them.
Yes they were warm blooded
Bearing in mind that lizards shouldn't even be part of herpetology, but some kind of cold-blooded precursor to the rest of aves, then yes. Big yes.
And don't start throwing megalothermy about. It's an embarrassing parachute for biologists with a piss-awful grasp of physics.
Re: Broken Window Theory
Police are citizens, too? Really? Not a paramilitary force, as has been put about by various members of the Met?
From the reading of the report, I'd have said it would have been quite obvious to any bystander who and where the ire was being directed, and that it was not cursing in their direction. Context is everything, Jim. So why those in earshot but utterly unaddressed should feel harrassed or assailed by what is in essence, just a sound, is beyond me, and I would have thought anyone with a modicum of temperance and reading comprehension.
And he didn't query it. He called bullshit.
One woman is not a party. Nor a mandate.
It's merely because of the handful of confirmed reports of wolf attacks on humans in the Fennoscadian area in a *two hundred* year period were on women :p
There have been no recorded wolf attacks on humans in that region since the 1900s, and some of the recorded ones in regions such as Russia appear to be utter nonsense - a wolf carried a 17 year old girl *by the throat* over a four-foot fence? P*ss off. A Ridgeback couldn't do that.
Well, it appears that wolves are the new threat in Sweden, after Larsson's poor grasp of maths.
Poor, maligned zinc...
I like the way that a barely-transition metal essential to mitochondria gets the same shoeing as lead...
You could of at least had the decency to name cadmium and mercury :-p
Just of fthe press, huh?
Except that Robert Sapolsky and his whole lab have been making this known, this specific aspect, for over three years, and that Leeds and Oxford Unis have been talking about it for at least six...
What are we, the Daily Mewl now?
I'm 6'6", weigh between 195-200lbs (depending on how much riding I've been doing recently) and my Focus (penultimate model) is the second most comfortable car I've ever driven. Maybe it's because I don't have the muscle tone of a beanbag.
Falt_Steve beat you to it by three hours :-)
The most potent irony...
Is that one of those 'green scientists' is holding a flask of potassium dichromate and one of chromic acid. Not exactly best friend chemicals with the green lobbies right now....
Re: I thought he was supposed to be the wrong guy now?
When has that *ever* stopped the Met?
It's a lot nicer than some coffee tables I've seen...
Actually, that periodic coffee table has spaces reserved all the way up to element 118. So there. Theodore Grey's momma didn't raise no fools.
Second, Oakleys would almost certainly have a quiet word about trying to name anything after it's ear-sock and nose-piece wondermaterial.
...Ignored people like you
I find throwing a wobblie about the slip in moral fibre against your ephemeral and mostly-historically-inaccurate behavioural standards works very much better if you abide by your own cobbled-together standards.
Also, probably because as the BBC are aware, words with lots of 'e's are far more common.
'Humorously'. And the 'H' is redundant, unless you're often given to spouting opinions you only pretend to hold.
I take exception to people taking exception to my choice of words. Words only have their power, contrary to V, because their speakers give them such.
The only downside of course to 3D Printing structures is those that intended to have anisotropic mechanical properties, like, oh, I don't know EADS airframe parts.
There's a reason why we still forge metal.
With heat, and everything.
Somehow I can't see Simon Callow playing *any* role in this one...
Re: True Alchemy
You beat me to it.
Now, if they'd pointed out a requirement of this experiment was something else, something nasty, further up the china, like aqua regia, just to make the gold chloride complex in the first place...
Wouldn't seem quite so simple after that, would it?
Re: DNA Everyone from birth
Ignorant troll is ignorant.
Re: He resigned, didn't he?
Now read which borough the CID spokesman was from, and think long and hard about the likelihood that bunch of Charlies have *any* idea what they're talking about, or even the moral fibre to do anything but blindly repeat whatever claptrap their press office printed out and shoved in front of them.
Beard? Check. Long hair? Check? Asswhuppin? Check...
I even have a T-Shirt to that effect :-)
Surely, coming home to find someone's turned your father's house into a shop and kicking seven bells of sh*t out of the lot of them could *only* be described as metal?
A modest question...
It's been said already in more grandiose prose, but succinctly:
What is this 'IF'?
Criminals failing to prosecute criminals. Whodathunkit?
The Feds won't touch this with a ten-foot pole because it would otherwise take away a rung of their own already precariously-balanced-legality information gathering systems.
Yet anecdotal evidence suggests that people who *air* their greviances straight away, rather than bottling them like the 'aggreable' types*, are the least stressed of all people. Blow your stack, over and done with, get on with your day...
*There's no such thing as an agreeable human. We're predators, murderers and thieves, just like all the other animals. A substantial section of the populous just forgot that when they moved into houses. It's still there, bubbling under the surfaces, which is why all the news reports always say "He was a lovely young man, never hurt a fly, we can't believe he hauled off with a hammer and brutalised 85 people to death."
Aye, there's the rub
"Young people have been a bit sick of hearing the spin on climate change, so this is a great way for them, a message for their politician about what they think."
Unfortunately the vast majority of young, or old, people who feel the need to tell someone what they think about climate change *don't* think. They merely regurgitate the second paragraph of the fourth page article in whatever newspaper they opened that morning. Much like those they refer to as naysayers or denialists.
There's only about five people in the whole world actually thinking about it. And none of them working at NASA.
And all the pocket-Mother Theresas put their oar in...
Or, alternatively, being the subject of a many-sided smear campaign that our gloriously easily led friends in the charities are beign unwittingly dragegd into. Have you ever dealt with any of the Red Cross/World Vision (especially) lot? As dumb as a box of rocks.
Let's see what comes out in the wash. After all, it's not like most of the world media is as honest and agenda-free as this here august organ.
We *are* blaming them
The stick they receive is rightfully deserved on all and every account. They choose which prosecutions to proceed with, and the buck stops *there*.
This is the same bunch of spineless, fascist s$%tweasels that chose *not* to prosecute in the case of the murderer of Ian Tomlinson. Or the attackers of Mark Aspinall and Nicola Fisher. And who didn't even notice when Jen Charles de Menenzes was assassinated in a tube station.. or...
You get the picture.
Dumber than a box of Ehlers
As was said before, and before, and before...
About the easiest way to turn a rape into a murder.
Can we have some new news, please?
I was gonna refer to the slightly more heartfelt Wesley Snipes' Blade in the circumstances:
"M*th*rf*ck*r, are you out of yo' damn mind?"
We need a pissed-off vampire icon.
Re: Why name the poor sod?
Because there' s nothing like riding the wave of iPad indifference into fresh new rolling vistas of free PR for another upcoming sh*tty device by 'accidentally' leaking a hush-hush prototype to the kind of bottom-dollar journoscum that Gizmodo have become.
What other kind of twisted reality do you expect from those fruit?
