Be sure to check out the Rock Dog Music Festival on Saturday, July 11th, 2009. The Rock Dog Music Festival will take place at 9000 Cardwell in Livonia, Michigan (zip code 48150). JON AUER: To me, it"s become both less precious and yet more accomplished somehow. I"d point to the years of experience together and apart as the reason we have so event wristbands much more creative water to draw from the well so to speak. Intensity Not all sport wristbands exercise needs to be intense but some of it definitely should. Make sure that at least some of what you"re doing for movement challenges you physically - it"s how you will improve your physiology. This could mean adding sprinting, or burst training, or even just revving things up enough to break a sweat. What you do before and after the date destination can make or break the date, so mentally walk through the date ahead of time to be sure you have covered how you will get there - who will drive home or will you cab it? Being spontaneous is really fun too - so if you know your partner well enough you could even pack a surprise bag for them and stay overnight somewhere after the date. Off Broadway is one of the few St. Louis music venues that attracts indie rock and punk bands that are up and coming, but that aren"t completely obscure. A perfect example is the brand new psychedelic folk group Here We Go Magic, which played a beautiful set at Off Broadway a couple weeks ago. The band had stopped in St. Louis on it"s way to the festival wristbands, where they played a ton of shows that got pretty impressive reviews. And the gun slingin", whiskey guzzlin" indie rockers Murder By Death are scheduled to play at Off Broadway in May - it"s bound to be a more appropriate atmosphere than if the group performed at the Pageant to the tune of $5 Budweisers. Opting for a pity party on the couch with a month"s supply of potato chips because you missed working out this week? Or because you gained a few pounds? Really? Get up! Do something! Even if it"s 10 squats (or deep knee bends, if "squats" sounds like too much work), do something. March in place. Move your spine. Put a little Elvis in that pelvis. Smile. You"re getting better now. Carry on. True to it"s name, the bar is a few hundred feet west of South Broadway Street. Crime can be thick in this part of St. Louis, so be observant and don"t flash wads of cash to random dudes hangin" out in alleys. My first introduction to the venue was when a friend informed me she had been robbed walking from her car into the bar. Her sob story had a positive twist though, because the bartenders at Off Broadway fed her free drinks all night!
WASHINGTON - A team of Chinese scientists has used graphene to create an artificial gas detector that is as good as a dog"s nose.
The study, reported Wednesday in ACS Nano, a monthly scientific journal of the American Chemical Society, showed that the graphene-based nanoscrolls can mimic a dog"s sensitive sniffer, which is lined with millions of tiny capillaries.
It is well known that dogs have a better sense of smell than humans. For years, scientists have been trying to develop an artificial detector that is just as good as a canine"s nose.
Drawing inspiration from the capillary structure, researchers from South China Normal University and Beihang University found a way to modify the graphene with a polymer to make high-quality nanoscrolls.
These nanoscrolls have a large surface area like that in dog"s nose. They are stable at high temperatures, and are strong and durable.
Previous studies have produced the graphene-based nanoscrolls, which are nanosheets of graphene rolled up in continuous and uniform manner.
But they are difficult to manufacture, consume a lot of energy and difficult to scale up.
And past studies have used raw graphene or modified graphene that either left behind some unrolled structures, or shriveled up and aggregated, respectively.
The team prepared graphene-based nanoscrolls with the addition of poly or sodium-p-stryrenesulfonate, using the freeze-drying method to create uniform, unaggregated structures.
It showed that the nanoscrolls had a wide, tubular shape, and almost all of the graphene was rolled up.
The researchers then incorporated the nanoscrolls into a gas sensor, which was highly selective and sensitive.
They said that this method had the potential for large-scale production.1 inch wide rubber bands glow wristbands bracelet maker online wristband sports trio spinners
