Why do i need this in the first place?well, to make things short, i have a prototype, called a smokers' quit watch. it is a digital watch with a smoke detector. It records the time the user had smoke. After we presented the prototype, we were asked to make the design detect only the smoke of a cigarette and not any smoke.So the question is, how do we do this?where in the philippines. if we would buy this kind of detector? how to build one for ourselves? any ideas?
Go to Start, All Programs, Accessories, System Tools, Disk Cleanup let it scan your drive, then when it shows you a list of things that can be cleaned, click the tab at the top for more options at the bottom of this tab System Restore shows up with a button click that button it will delete all but the most recent restore point this should get rid of the problem - if this doesn't get rid of it, turn system restore off, reboot and turn it back on this will get rid of it
They tried to when the building collapsed but the water supply went dry, they had to get the fireboats moved in and hooked up, and had to rig long lines of fire hoses out to where the water was still flowing in the underground pipes. The collapse of the buildings damaged a whole lot of stuff underground. Plus there were so many constant clear the area, rubble unstable calls. The reason why so many firefighters died in 9/11 was because a lot of them were trying to climb up the stairs while the buildings were still standing to get to the fire up on those high floorsand they had to use the same stairs that the workers were evacuating on so there were jamsand from what I heard on some reports the stairways could only accommodate 2 people abreast at a time (and firefighters carry a whole lot of equipment attached to them). No one expected the buildings to collapse and certainly not to collapse so quickly. And between the jet fuel feeding the fire and then the stuff in the offices that caught fire and omitted all those toxic fumes, it would have been a losing battle (not sure they could get water up that high if the pumps on the roof failed). The guys on the ground were covered with that awful white dust, breathed that stuff in, while they stood pouring water on the many fires that broke out after the collapse, and the piles of rubble were so unstable. Stuff was falling down on everyone. They also had to deal with whether to pour water down a smoldering hole when there could be survivors down there who may drown. Those guys had a whole lot to deal with and did an unbelievable job, I know I couldn't have put myself in danger as they all did.
They tried to do everything possible to get victims to safety.
