Smaller particles stay aloft a longer --not shorter-- period
Funny, I was always told that they dropped out quicker due to less surface area for air molecules to hold them up. Learn something new every day, hey:-)
True - in our location at said coal mine, the temperature goes from 2 degrees C in winter to 45 deg C in summer. Heating's fine in winter, we have a number of 800 degree C furnaces in our lab;-) Cooling's sometimes an issue in summer, but the humidity is very low in summer, and with the lab sealed pretty well (seals under doors etc), there's actually not much airflow through the system when it's closed, so the A/C keeps up ok.
Of course, when I say "lab", it's just a 3 room portable building with no ducted air, just wall A/C's with about 30,000 BTU total.
We *do* work in a coal mine and we *are* aware of "miners lung", thanks very much:-)
Yes, we wear dust masks when outside collecting / grinding samples, and also have a 6 monthly respirable dust check, where we get to wear a minature version of what I've described above (battery air pump , cyclone, filter) around for a day to check on the amount of respirable dust we breathe in. Every 5 years you're required by law to have a chest x-ray to check for silicosis if you still work in the industry.
It's generally only particles below 10 microns that you have to worry about breathing in, as they're the ones that *never* come out again. Particles bigger than 10 micron get removed via mucus and cilia in your nose/airway/lungs without much hassle. Luckily, 10 micron particles and below generally don't stay suspended in the air too long, they drop out pretty quick.
And anyway, we try not to go outside the lab too much. (Ahhhh! the light! It burns, it burns!!):-)
I'm not sure on your lab setup, but if the dust is *outside* the lab, try a pressurising fan setup.
Get a 2 inch outlet cyclonic type air filter, typically used in tractors, bobcats and small motorised machinery. Hook it to the suction of a blower fan, outside your lab. Duct the exhaust of the blower *into* your lab. Try and close as many doors and windows as possible.
The blower will pressurise your lab with clean air, which will try to escape out all the nooks and crannies in your lab, keeping the dust outside.
Don't forget to check the filter every couple of weeks until you get a handle on the maintenance interval required, and don't get a cyclonic filter too big for your fan, as they need high airflow to spin out the dust particles effectively.
This works for a coal lab of ours that is located very close to a 100,000t stockpile of loose,dusty coal. The dust is bad enough that if a blank piece of paper with a pen on it is left outside the "clean room" (still inside the building) you get a "shadow" of the pen on the paper in about 6-8 hours.
Ultimately the best cure for curing terrorism is killing the terrorists and destroying the infrastructure (states) that support it. There really is no other way.
How about finding out the reason why they want to hate and kill you, and doing something about that? Apart from a few true maniacs in the world, people do not suddenly wake up one day and decide to wage war against some other party, they normally require a pretty compelling reason to do so.
My personal opinion is that you cannot surgically remove all the "terrorists" in the world, without pissing off someone. A relative of a "terrorist", some poor random person in the street who lost his kids when you blew up a building to clear out a "terrorist cell", there's always someone who'll be more than a little pissed off that you killed someone else. And so, you end up never getting rid of all the angry people who want to kill you, but instead tend to make more enemies. This cycle continues until there's enough angry people that finally they outnumber you, and then you'll get eliminated, because you've become the "terrorist".
If this copyright law dates back to 1968 than there are bound to be some loop-holes that should get these guys off. They just need a decent lawyer.
No,it makes it a lot harder, since all the other cases since 1968 have been testing the law as it stands. The police (in general) will not prosecute if they determine that there's a previously known escape / loophole in this law that fits these circumstances. They make pretty sure that the law applies before going into court.
It would be nice if they actually spent the fuel tax on roads and infrastructure. Currently in Australia there's a billion dollar discrepancy between spending on roads and fuel tax input every year.
Our government takes 38 cents a litre (about 1USD/Gallon) in fuel excise and returns 6 cents a litre (0.16USD/Gallon) in road funding. I paid 101.9 cents per litre for petrol a month ago - that's 2.75USD a gallon. It's certainly enough to make you start looking around for alternatives, that's for sure.
*cough* wasn't there a fault in win95A (a timer glitch?) that only let it run for 49 days without locking up?
And it took 2 years for anyone to notice because , lets face it, win95 got rebooted a whole lot more often than that because of all the other bugs.

This reminds me of the
Nuclear armed Jeep.
Basically, a standard Jeep with 40 kiloton nuke with a launcher that only carried the nuke one an a half miles. What the hell were they thinking?!? Might as well have just driven on up to the enemy and said, "here, hold this for a minute, willya?"
Wouldn't want to be the poor sap assigned to that jeep.
They're on the internet. Normal tcp/ip traffic from a number of hosts should be no hassle to them - if they don't want it, unplug.
How about a small monitoring program that just pings once a minute to make sure that their host server is alive? It would be a service to them , as a token of our appreciation for all the informative emails they've been sending to us.
We *need* to do this , because *so* many people would miss out on their *important* products and services if their server failed!!!
And since their messages simply *must* be delivered , we'll need a few redundant clients to make absolutely sure that things are ok.... about 10,000 clients should give us five nines.
Hey, we could even email them a warning if the ping time was over a set limit!
No cpu that I know of will erase an entire hard drive in a freak mistake...It'll just stop working.
Yes, but when you're overclocking, there's a fuzzy area between "stop working" and "normal" that includes "occasionally mis-execute an instruction" and you can be damned sure the latter will occur sooner or later if you run a processor over it's rated speed.
Just for fun, it might mis-execute an instruction in the routine that keeps your file allocation table (or inodes) intact and up-to-date. Then the next write operation your now-malfunctioning system does is all over the shop, and all over your data. *poof!* Suddenly you can't read your root directory, and you need to reinstall from your carefully maintained backups;-)
Ok, we post to slashdot. We're geeks, we're (most likely) smarter than the average person.
A large proportion of people posting say something along the lines, "This is an invasion of my privacy! I don't need to do homework, I've aced all my tests, I can stand up in front of class and make it up as I go along!"
This kind of thing is not for the 5% or so of 'smart' children in school. It's for the other 95% that struggle to grasp the concepts in the limited time that the school has (for whatever reason) to teach it to them.
So, before you type another, "I'm leet! I need no homework!" post,think about the poor dumb schmuck in your class who can't grasp logarithms and is going to struggle to get anywhere near a white-collar job. That's what the homework is for.
(Parent Mode on) If you're so good at your studies, it'll only take you 5 minutes to whiz through your homework, and god forbid, the little bit of extra practice solving differential equations might actually help you one day. (Parent Mode off)
When I am reading the "war news" now, I take the very highs and the very lows from all the sources, and throw them away, then average the middle, that is most likely the closest to any sort of "truth" being reported.
Actually I've found the daily summary from The russian intel guys to be quite objective, seeing as they aren't "Allies" to anyone in particular in this skirmish. Seem to have the most rational viewpoint so far as opposed to all the media hyperbole.
In that case its wrong unless you pay them whatever miniscule ammount it cost
(Checks last bill) Hmm.. 22MB at 15c/MB.... $3.30... wouldn't want *too* many people doing that, thanks. Just consider yourself lucky that you live in a country with cheap internet access.
I'd suggest cement - that gap is way to big for normal fillers.
The "Standard Mix": 4 parts sand 2 parts gravel 1 part cement.
Mix with water until it's a smooth paste, and trowel it on in. 'Float' your trowel over the surface a few times to get a smooth finish. Leave it a few days to cure and you're ready to go.
It's all very well and good to be willing to lose your job over your principles, until you have a wife and two kids to support.
"Honey I was fired today because my principles interfered with my job. I believe that my postion was unethical, I made a fuss about it and was sacked."
"You stupid sack of shit! What are we going to eat now? grass? How the hell are we going to pay our mortgage? You Idiot!"
(Chipping in) Besides, you don't *need* model rockets - there are plenty of people willing to die for their beliefs.
What? you want to drop nerve gas on new york? Ok, here's a young idealistic recruit who's happy to drive his car into the middle of town with a bootload of the stuff. Easy.
I went a little cross-eyed when I read the details in your link... but there appears to be a little problem - at present, the U.S. isn't at war... by the legal definition of war anyway. Therefore "Prisoner of War", and all the legalese in your link, doesn't really apply.
I've had smb port logging on in my firewall for the last two years, connected to a modem with a static IP.
Not a day goes past without at least a dozen attempted netbios connections from various different IP's. I also get about the same amount of people trying to telnet / ftp / ssh in as well.
Glancing through the emails from logwatch over the years, it definately seems to be increasing.
