Esophagogastroduodenoscopy (EGD) is a diagnostic procedure that allows the physician to diagnose and treat problems in the upper gastrointestinal (UGI) tract. The doctor uses a long, flexible, lighted tube called an endoscope. The endoscope is guided through the patient's mouth and throat, then through the esophagus, stomach, and duodenum (first part of the small intestine). The doctor can examine the inside of these organs and detect abnormalities.
Onions are transported in wide-meshed jute fabric or plastic bags, crates, boxes, cartons, baskets or fruit crates. Small-meshed bags are unsuitable for transport due to their low permeability to air.
There are two key aspects to onion routing. First, the Tor network is composed of volunteers who use their computers as ânodes.â As mentioned earlier, during normal browsing, information travels across the Internet in packets. When a Tor user visits a website, however, their packets do not simply travel to that server. Instead, Tor creates a path through randomly assigned nodes on that the packet will follow before reaching the server. The other important aspect of onion routing is how the packets are constructed. Normally, a packet will include the senderâs address and the destination, not unlike a letter.
