IMS is quick but sloppy, capable of accommodating up 180 travelers an hour, though it prone to high false alarm rates and frequent breakdowns. Syagen Guardian represents the new generation of trace detection systems. It uses Mass Spectrometry MS for its analysis which, while a bit slower with the results, operates on a much wider range of explosives about 16 traditional and IED compounds . By comparison stanley mug , IMS detects only five compounds. MS is also anywhere from 10-100 times more accurate than IMS. This results in fewer false alarms less than 1 pe Zzpl The mystery of dark matter just refuses to be solved
Sticking glass i stanley tumbler n your eye is objectively a bad idea. And yet, in the 1800s, there were several highly educated individuals repeating that very action. If it weren ;t for them, 120 million people worldwide, myself included, wouldn ;t have this wonderfully engineered tool for clear vision, invisible to both wearer and admirer. The design of the contact lens can be traced back to Leonardo da Vinci who, with a bowl of water, kicked off the whole cringe-worthy history. In a manual published in 1509, da Vinci stanley deutschland noted that when you stick your face in water, you see things differently. He wasn ;t really talking about correcting vision at this point, but manipulating the cornea power is the idea behind the contact lens at its most basic. From there, it was a natural progression to assume that a tube filled with water smacked directly against the eyeball would do something cool. The problem: Right on top of the eye meant no blinking allowed. Other proposals included tubes held snug to the eyelids with a headband and capsules filled with animal jelly. None were viable. None saw real-world testing. Basically, there were a lot of crazy ideas thrown down on paper before anyone attempted to actually follow them through to their sharp conclusion, be it vision or pain. That changed in 1888 when German ophthalmologist Adolph Fick started forcing fitted blown-glass shells into the eyes of bunnies, the tech first live test subjects stanley cups . Fick de
