Quote: Dogs for landmine detection

Dogs are considered so far the best detector of explosives. Their sensitivity to that kind of substances is estimated to be a factor of 10,000 higher than for a man made detector. On this consideration Mechem Consultants based their Mechem Explosives and Drugs Detection System (MEDDS). The system they developed overcomes the main problem in the use of dogs, namely the relative small period of effective work they can provide (about an hour a day). The way dogs are normally used is in the search mode, i.e. they are brought near the place where mine presence is suspected and they start searching for the source of the particular scent they have to identify. The idea underlying MEDDS method is to save dog's energies by bringing to it the source of the scent instead of using the dog in search mode. The method has been proved succesful for demining of roads . A mine resistent vehicle runs on the road with a vapour collection box endowed of chemical filters fitted on its front. Road is run along in stages of about 1 km; at each stop vapour collected from the scanned area have to be associated to that area by a physical marker or a GPS location, and a new filter is put in the collection box . Vapour collected in filters are then brought in an uncontaminated area where trained dogs start identification of explosives in the different samples. That allows to discriminate relevant sections of the roads where dogs can be used, now in search mode, for a more precise localisation of the landmine. At this stage, if the mine contains a metal part, a metal detector can be used to get the exact position. Then the mine can be digged up without exploding it to minimize damage to the road. Otherwise a fuel air charge can be used to detone it in place.

An advantage of the MEDDS method, with respect to man made detector used in roads demining, is that due to blow of wind, vapours are collected from a larger area than just the road line, and it allows detection of mines buried nearby the road. Moreover, vapours collected in chemical filters can remain on the absorbent material for up to four months. An other important and appealing feature of biochemical detection is that it detects explosives directly; for that reason it has been proved to be the more effective method for explosive charges buried without a case.

also, during WWII, Americans would 'enlist' their dogs as a patriotic gesture to help out. Remember, technology wasn't what it is today. After all, dogs blowing up are better than humans blowing up.

If GWB were to call for any dogs to be enlisted today for Iraq (which I know won't happen), but if he did, I would enlist Wrangler in a heart beat if it helped a human survive.

You hate dogs, we get it. Now please go get checked out.

They're dogs. Noone who eats beef has any right to complain about this.

on the contrary, I love dogs, and I love my dog, but I prioritize the importance of animals in my life, which you guys can't seem to understand.

God>Family>country>job>pets

My priorities are perfectly in order, just trying to get a feel for everyone else

Leon your sad attempts to piss off animal fail miserably. Maybe you xcel at throwing dead puppies at little children, but not on this.

Leon, no one is FOLLOWING YOU.

What you fail to understand is this is a forum.

Its not an autobiography.

You have presented yourself as a sick individual. Now what do you expect?
Presents for your cowardice?

leon , leon , leon ... you are making a habit of this and you are not convincing anyone of anything, besides your ablity to throw dead dogs at your daughter, your desire to eat dead dogs in other countries, your wish for dogs to be blown up in Iraq and your complete lack of debate skill.

actually, it`d be funny if you kept it up, keep us entertained by displaying a totally unique philosophy and abundance of counter-productive ideas.

If I had a choice between one hundred dogs or one human being killed in an explosion. I would pick the dogs. Without a doubt.

Dogs and other animals are expendable, humans are not.

humans are expendable, they are used in war for political gain, used as slaves for manufacturing products, there is plenty of examples.

Leon Czolgosz · Joined: 05 Apr 2006 Posts: 190

you're right, but dogs are more expendable

Why are we even discussing this when there are MACHINES that can and do eliminate the land mines? Is it me or do you just want to see dogs die?

Yeah it's amazing how wonderful dogs are and how much they can help humans!

But there's still a dude five feet away from the land mine.

Dogs are much cheaper than a machine, so naturally, they will be used more now.

Maybe you didn't realize it, but they're using dogs to sniff out the mines, just like the FBI, CIA, ATF, and Border Patrol does, not using them to blow the mines up.

Not for these....

There's also one that the US military uses that’s kinda like a tank but in front it has these huge 8 ft chains that rotate and beat the ground setting off any land mines. Although I can't think of the name, thus no picture.
