"Eye" In The Sky Will Find Your Diamond.
For us in the Diamond Trade, one of the highest compliments you can give a colleague is to tell him, "You have a Good Eye" when to it comes to correctly evaluating diamond rough for manufacturing or for assessing and evaluating prices on polished goods.
Now this "Good Eye" has taken a technological leap and is sure to revolutionize the Diamond Mining Industry with the announcement by the Canadian company, Gedex Inc. of their new proprietary technology that will pinpoint diamond deposits and make Canada the largest diamond producer in years to come.
The Globe and Mail reports today that Mississauga-based Gedex Inc. has developed an airborne surveying system capable of "seeing" as far as 12 kilometres beneath the Earth's surface to identify precious metals, oil, gas and minerals that are invisible to current systems.
Gedex's system, a new twist on a century-old idea, has already won the company a mining research award, the first ever given by the Mining Journal, the authoritative 170-year-old British publication. The award was adjudicated by an international panel of experts, who cited Gedex for "primary research that is expected to have the most significance for mining and mining equipment in the future."
Gedex's new system, known as a High Density Airborne Gravity Gradiometer (HD-AGG), uses tiny variations in gravity to identify geological structures beneath the ground. Among the structures it can precisely spot are kimberlite pipes -- vertical columns of rock pushed upward into the Earth's crust by volcanic action far below -- that often contain diamonds.
The Gedex system has its roots in the 19th century, when a Hungarian physicist named Roland, Baron von Eotvos, discovered that variations in gravitational force could help in geophysical exploration, a concept known as gravitational gradiometry. The U.S. military used his ideas to build navigation and missile-targeting systems for submarines during the Cold War.
Gedex also developed a way to use superconducting quantum interference devices, or SQUIDs, to measure tiny variations in gravity. These electronic devices work only at extremely low temperatures, so Gedex encased its instrument in a cryostat, a kind of high-tech cousin of the Thermos bottle that keeps it at roughly absolute zero.
In use in the field, an airplane carrying the HD-AGG flies over the area to be explored. A single pass can cover a strip 60 to 100 metres wide for preliminary exploration; for more detailed mapping the plane flies lower, covering less terrain on each pass.
The device measures minute gravity variations that translate into a colour-coded map of what lies beneath the ground.
DeBeers is hot to get their hands on this technology and is already in talks with Gedex.
This technology will revolutionize diamond mining and exploration.

You share a few excellent ideas on this article. I did a search on the keyword and found nearly all bloggers will agree with your blog.

If you're still on the fence: grab your favorite earphones, head down to a Best Buy and ask to plug them into a Zune then an iPod and see which one sounds better to you, and which interface makes you smile more. Then you'll know which is right for you.

Well written post, well researched and usefull for me now. I am so glad you took the time and effort to write this web page. Will be back in a while to read more about this issue.
Posted by: Migraine Zanzibin on March 23, 2011 9:57 AM
Sorry for the huge review, but I'm really loving the new Zune, and hope this, as well as the excellent reviews some other people have written, will help you decide if it's the right choice for you.
Posted by: christian louboutin outlet on March 23, 2011 10:24 PM
The Zune concentrates on being a Portable Media Player. Not a web browser. Not a game machine. Maybe in the future it'll do even better in those areas, but for now it's a fantastic way to organize and listen to your music and videos, and is without peer in that regard. The iPod's strengths are its web browsing and apps. If those sound more compelling, perhaps it is your best choice.

Thanks a lot, I have just now been looking for information about this issue for ages and yours is the best I have read so far.
Posted by: job internet on March 25, 2011 3:01 PM
I have read that page and if I might I would like to tell you some useful suggestion. Maybe you may write more articles reffering to this one. I would enjoy to read some more about it!

I'll gear this review to 2 types of people: current Zune owners who are considering an upgrade, and people trying to decide between a Zune and an iPod. (There are other players worth considering out there, like the Sony Walkman X, but I hope this gives you enough info to make an informed decision of the Zune vs players other than the iPod line as well.)

Great website! This is the type of information that must be shared around the internet. It is too bad that it doesn't rank higher on the serps!

The new Zune browser is surprisingly good, but not as good as the iPod's. It works well, but isn't as fast as Safari, and has a clunkier interface. If you occasionally plan on using the web browser that's not an issue, but if you're planning to browse the web alot from your PMP then the iPod's larger screen and better browser may be important.

I have been exploring on internet more than 2 hours today, yet I never read any compelling web page like this one. It's pretty worth a lot of for me. Personally, if all web owners and bloggers made good info as you did, the web will be much more beneficial than ever before.

Zune and iPod: Most people compare the Zune to the Touch, but after seeing how slim and surprisingly small and light it is, I consider it to be a rather unique hybrid that combines qualities of both the Touch and the Nano. It's very colorful and lovely OLED screen is slightly smaller than the touch screen, but the player itself feels quite a bit smaller and lighter. It weighs about 2/3 as much, and is noticeably smaller in width and height, while being just a hair thicker.

I know th is is nota favorite opinion, but I certainly adore it. Why not strive something distinct? Why not seek to use th is object and animation to represent the interconnectedness on the neighborhood? Th is Burnley object as logo is various in the dull shit and aesthetic nightmares we??? ve been seeing recently. In my opinion, th is is actually a win.

The whole stage of [logo] design just isn't to show off??? what you may do. It is not about bells and wh istles. It's that sort of thinking that has a good deal of current designers applying gradients on every single style aspect as if they had something to complete with v isual communication. The lion drawing does notneed any longer pol ishing. From in which I stand, It will be at a stage where it could ONLY be applied or d iscarded. When you think it requirements extra pol ishing ,that it will be too cartoony??? , or that you have styl istic objections with all the remedy, then maybe you??? re from the improper occupation. You??? re complaining about anything quite basic to modern day graphic design. I have read from a few of the greats on the topic of design and I do believe that I've a take care of on the subject. It's not your take care of, I have an understanding of that. What I do notunderstand is your design philosophy. It will be well known that you simply consider Nike and Shell are terrific manufacturers. Maybe you??? re an Worldwide Model zealot who thinks a grid is a reply to every single layout issue. Maybe that is definitely what you meant by pol ished? Or maybe you??? re into plenty of pointless detail on a logo that may develop into no ise since it is shrunken down? I do notknow.My grammar is usually wonderful, thank you for asking. It can be my spelling that was off in numerous regions and for that, I apologize, but, you know, if my grammar was anyplace close to as horrible as you declare then you??? d have had a tough time comprehending what I wrote. There could well be next to nothing for you to react to. I do notknow about you, but it is really hard for me to obtain angry at gibber ish in particular when I've no strategy what it means.
