what is the gel used thats used when doing an Ultra-Sound called?

There are various brands but probably the most common in use in hospitals is AquaSonic (link to company website below.)\n\nThe gel facilitates the transmission of sound waves from the ultrasound probe to (and thence through) the skin. If there is air under the probe, the waves are reflected off it and you can't image the tissue underneath. Even a tiny air bubble will distort the wave/reading. The technical explanation (from Wikipedia):\n\n"Ultrasonography (sonography) uses a probe containing one or more acoustic transducers to send pulses of sound into a material. Whenever a sound wave encounters a material with a different acoustical impedance, part of the sound wave is reflected, which the probe detects as an echo. The time it takes for the echo to travel back to the probe is measured and used to calculate the depth of the tissue interface causing the echo. The greater the difference between acoustic impedances, the larger the echo is. The difference between gases and solids is so great that most of the acoustic energy is reflected, and so imaging of objects beyond that region is not possible."\n\nIt's a water-based gel (probably rather like KY). Most companies have proprietary formulae so I can't say exactly what they're made of. The second link is a rather neat discussion of different types of gel.

Treating benign and malignant tumors and other disorders, via a process known as Focused Ultrasound Surgery (FUS) or HIFU, High Intensity Focused Ultrasound. These procedures generally use lower frequencies than medical diagnostic ultrasound (from 250 kHz to 2000 kHz), but significantly higher time-averaged intensities. The treatment is often guided by MRI, as in Magnetic Resonance guided Focused Ultrasound. \nMore powerful ultrasound sources may be used to clean teeth in dental hygiene or generate local heating in biological tissue, e.g. in occupational therapy, physical therapy and cancer treatment. \nExtracorporeal shock wave lithotripsy uses a powerful focused ultrasound source to break up kidney stones. \nFocused ultrasound sources may be used for cataract treatment by phacoemulsification. \nAdditional physiological effects of low-intensity ultrasound have recently been discovered, e.g. the ability to stimulate bone-growth and its potential to disrupt the blood-brain barrier for drug delivery. \nUltrasound is used in UAL (= ultrasound-assisted lipectomy), or liposuction. \nDoppler ultrasound is being trialled for use in aiding tissue plasminogen activator treatment in stroke sufferers. This procedure is called Ultrasound-Enhanced Systemic Thrombolysis.

i think the best water aborsbing material is silica gel

I dont know that "SLow Gold"\nBut I know, that time stretching is not a problem for modern audio software.\nI suggest you get a free audio editing software (just do a search, try downloads.com), some of them have that feature. Some softwares have a trial period, but you still can use that feature.

Use a Yonex. Buy a carbon or composite material racquet.\nBefore you buy one, test a few, feel the feedback that you feel on your wrist everytime you whack the shuttle. A good racquet will give the "feel" of the shuttle, without jarring. \nGut tension should be good, with a twang or twing sound instead of the thwack sound...:) That sounded funny, but thats the best I can do to describe the sound...\nI would budget between Rs.1,300 to Rs.3,500 for one... depending entirely on the depth of your pocket.

I used Wilson racquet, it get the job done just like any racquet, and a lot cheaper than other brands.

It is the process of disrupting biological materials by use of sound wave energy.\n\nSonication is basically a process by which sound waves are passed through a medium - either directly or indirectly as in a water bath.  We, where I work, use it to quickly dissolve solute in solvent... ie. reagent grade vitamins into Mother, stock and working standard solutions.\n\nThe links below are of Sonicators.

There a a few different types that I use in the following cases:\n1. gut (plain or chromic) - these are dissolvable. Good for cases where a follow-up isn't really necessary. But can collect plaque about them, and become annoying to patients when the loosen up. The chromic type can last weeks, and I don't see the need for them in dentistry.\n2. black silk - these are non-dissolvable. Easy for the dentist to see and use. Also collect plaque. I don't use these much anymore.\n3. monofilament nylon - non-dissolvable. Easy for dentist to see but more difficult to place and remove. Much cleaner than gut or silk.\nThe dentist will tell you if you need to come back to have your sutures removed. If you can't remember, then call his office.

It does get hard, someone I knew used it. It feels like hair gel.

Banana Boat vitamin E gel works wonders! I've used it many times.

You should try this page\n\nhttp://www.sonorex.com/us/

I don't now is it dangerous bcs for this conclusion you have to use it for a long time. I tried for several hours and it didn't affect me then I stopped. Cool Edit Pro can do almost the same thing as brainwave gen. but you have to make samples by yourself. Brainwave has a bunch of presets. You can try it without fear.

Gel RT. Yes, it's affordable.

Both answers are correct, except for the "no" part. Agarose is made from seaweed and when heated in a buffer, cools to form a gel. The gel is used for gel electrophoresis, which is used to separate DNA fragments of different sizes.\n\nThe question is kind of funny though, because if you are doing genotyping, you should know a bit of this.

Compound W.\nThere is also a new product on the market where you can freeze them off.  Uses similar treatment that doctors use.\n\nI've also heard that the duct tape thing works well.
