search


he new date option, screen from my Iphone

1. Do a normal search in Google
2. Put &as_qdr=d  after the search string. Just copy and paste it just behind the last digit of the URL you see after you do a search in Google. Now you get only the sources from thelast 24 hours indexed by Google (keep in mind: the date that Google found the info is not always the actual publication date). Put&as_qdr=d2 behind the string to get sources of the last two days

Back-up


Continuing on with the complaints about the long backup process every time you sync your iPhone, here is yet another little trick that should help to cut that time down a bit, and thankfully this suggestion will not involve turning off the backup process.
Thanks to a nice forum posting over on the HowardForums, you can now cut that sync time down and still be prepared should something unfortunate happen to your iPhone that forces you to have it replaced.
The process is simple and it involves turning off the ability to send diagnostic data to Apple.
With just a few easy steps you should be left with sync times that are much more manageable, of course this will not help if you add a bunch of new media or the first sync after you add some new apps, however regular or routine syncing should be much more pleasant.
After connecting your iPhone to your computer;
1. Uncheck the check mark from the “Automatically sync when this iPhone is connected” option in iTunes.
2. Unplug your iPhone and then plug it back in
3. Once iTunes launches again, right click on its name in the devices menu (on the left) and from menu choose “Reset Warnings”
4. Then click Sync in the bottom right hand corner
5. You will then receive a pop-up (see image below). Simply uncheck the “Do not ask me again” box
6. Now you can go back and re-apply the check to the “Automatically sync” option that you removed in Step #1

Magnetic resonance imaging - Wikipedia, the free encyclopedia


Magnetic resonance imaging (MRI), or Nuclear magnetic resonance imaging (NMRI), is primarily a medical imaging technique most commonly used in Radiology to visualize the structure and function of the body. It provides detailed images of the body in any plane. MRI provides much greater contrast between the different soft tissues of the body than does computed tomography (CT), making it especially useful in neurological (brain), musculoskeletal, cardiovascular, and oncological (cancer) imaging. Unlike CT, it uses no ionizing radiation, but uses a powerful magnetic field to align the nuclear magnetization of (usually) hydrogen atoms in water in the body. Radiofrequency fields are used to systematically alter the alignment of this magnetization, causing the hydrogen nuclei to produce a rotating magnetic field detectable by the scanner. This signal can be manipulated by additional magnetic fields to build up enough information to reconstruct an image of the body.
MRI is a relatively new technology, which has been in use for less than 30 years (compared with over 110 years for X-ray radiography). The first MR Image was published in 1973[1] and the first study performed on a human took place on July 3, 1977[2].
Magnetic resonance imaging was developed from knowledge gained in the study of nuclear magnetic resonance. In its early years the technique was
