Two spaceships are traveling together through the galaxy at close to the speed of light. Mounted on one ship is a laser that can fire pulses of light, and on the other, a mirror. The pilot of the first ship fires a pulse at the mirror, and watches as it is reflected back. A clock on board measures how long the round trip takes. But now suppose that he does this as the ships are passing an observer on a nearby asteroid. According to relativity theory, this observer sees the pulse moving through space at exactly the same speed that the pilot does -- namely, the speed of light. But he also sees the pulse traveling a longer distance, because from his perspective, he must add the forward motion of the ships to the motion of the pulse between them. So he measures a longer time interval for the round trip than the pilot does, because he is watching the pulse go farther without going any faster. This effect is called time dilation: if one observer is moving with respect to another, each perceives that the other's time is flowing more slowly. National Science Foundation

An experiment using civilian aircraft and atomic clocks to provide evidence for Einsteins time dilation theory. Time dilation applies to satellites that orbit the earth as they move forward in time by 0.01 seconds per year. This may not seem much but the clocks on the satellites need to take this into account in order to stay in time with clocks on earth.

What is Esophageal Dilation? Esophageal dilation is a procedure that allows your doctor to dilate, or stretch, a narrowed area of your esophagus [swallowing tube]. Doctors can use various techniques for this procedure. Your doctor might perform the procedure as part of a sedated endoscopy. Alternatively, your doctor might apply a local anesthetic spray to the back of your throat and then pass a weighted dilator through your mouth and into your esophagus. Why is it Done? The most common cause of narrowing of the esophagus, or stricture, is scarring of the esophagus from reflux of acid occurring in patients with heartburn. Patients with a narrowed portion of the esophagus often have trouble swallowing; food feels like it is "stuck" in the chest region, causing discomfort or pain. Less common causes of esophageal narrowing are webs or rings (which are thin layers of excess tissue), cancer of the esophagus, scarring after radiation treatment or a disorder of the way the esophagus moves [motility disorder]. How Should I Prepare for the Procedure? An empty stomach allows for the best and safest examination, so you should have nothing to drink, including water, for at least six hours before the examination. Your doctor will tell you when to start fasting. Tell your doctor in advance about any medications you take, particularly aspirin products or anticoagulants (blood thinners). Most medications can be continued as usual, but you might need to adjust your usual dose before the examination. Your doctor will give you specific guidance. Tell your doctor if you have any allergies to medications as well as medical conditions such as heart or lung disease. Also, tell your doctor if you require antibiotics prior to dental procedures, because you might need antibiotics prior to esophageal dilation as well. What Can I Expect during Esophageal Dilation? Your doctor might perform esophageal dilation with sedation along with an upper endoscopy. Your doctor may spray your throat with a local anesthetic spray, and then give you sedatives to help you relax. Your doctor then will pass the endoscope through your mouth and into the esophagus, stomach and duodenum. The endoscope does not interfere with your breathing. At this point your doctor will determine whether to use a dilating balloon or plastic dilators over a guiding wire to stretch your esophagus. You might experience mild pressure in the back of your throat or in your chest during the procedure. Alternatively, your doctor might start by spraying your throat with a local anesthetic. Your doctor will then pass a tapered dilating instrument through your mouth and guide it into the esophagus. What Can I Expect after Esophageal Dilation? After the dilation is done, you will probably be observed for a short period of time and then allowed to return to your normal activities. You may resume drinking when the anesthetic no longer causes numbness to your throat, unless your doctor instructs you otherwise. Most patients experience no symptoms after this procedure and can resume eating the next day, but you might experience a mild sore throat for the remainder of the day. If you received sedatives, you probably will be monitored in a recovery area until you are ready to leave. You will not be allowed to drive after the procedure even though you might not feel tired. You should arrange for someone to accompany you home, because the sedatives might affect your judgment and reflexes for the rest of the day. What are the Potential Complications of Esophageal Dilation? Although complications can occur even when the procedure is performed correctly, they are rare when performed by doctors who are specially trained. A perforation, or hole, of the esophagus lining occurs in a small percentage of cases and may require surgery. A tear of the esophagus lining may occur and bleeding may result. Complications from heart or lung diseases are potential risks if sedatives were used. Symptoms of thisdisorder vary and may include difficulty swallowing (dysphagia), painfulswallowing, regurgitation of food and weight loss. Further complications mayalso arise if the stricture is left untreated. Fortunately, esophageal dilation offers potential relief andhealing for those suffering from esophageal stricture, Dr. Julio Murra Saca perform a dilation with hydrostatic Balloon. www.murrasaca.com

http://www.PreOp.com Patient ED @ 617-379-1582 INFO Your doctor has recommended that you undergo a Dilation and Curettage, or D and C. But what does that actually mean? The uterus is part of a woman's reproductive system. It's the organ that contains the growing fetus. The cervix forms the neck of the uterus, and the vagina is the canal through which conception and birth take place. The endometrium is a soft lining that protects the fetus during pregnancy. Reasons for having a D and C vary. Most D and C's are performed because the patient has complained of unusually heavy menstrual bleeding. Other common problems include, uterine infection, bleeding after sexual intercourse, incomplete miscarriage or the presence of polyps - small pieces of extra tissue growing on the inside of the uterine wall.

Dilation And Evacuation Abortion Of A 23 Week Unborn Baby. Images from Nucleus Communications, Inc. All text from Fair Use. Once the women's cervix has been dialated, which is a two or three day process requiring two trips to the abortionist, forceps are inserted through the enlarged cervix into the uterus. The body parts are grasped at random with a large, long toothed grasping clamp. With the large, long toothed grasping clamp, the abortionist twists the limbs and body parts from the unborn baby -- and pulls them from the baby -- and pulls the body parts out of the vaginal canal. The remaining body parts, with the exception of the head, are grasped and pulled out. During this procedure, perforation of the uterus is possible. The head is then crushed in order to remove it through the vaginal canal. The placenta and remaining contents are then suctioned from the uterus. The body parts must be reassembled outside of the mother's body to be sure all was removed from the womb. If some body parts are missing, then the abortionist must continue to search for the missing body parts and retrieve them. At a gestational age of twenty weeks, the mother has been feeling her baby kick for the last two weeks. At twenty weeks gestation, the uterus is thin and soft, so the abortionists must be careful not to perforate or puncture the walls of the uterus. A second trimester dilation and evacuation abortion is a blind procedure. The baby can be in any orientation or position inside the uterus. The toughest part of the dilation and evacuation abortion is extracting the baby's head. The head of a baby is floats freely inside the uterine cavity. The skull pieces must then be extracted. Some abortionists have reported that on bad days, a little face may come out and stare back at you. Dilation and evacuation is the most common technique used for second trimester abortion. Typically done 13-16 weeks into pregnancy, doctors who specialize in abortion may use this technique into the 20th week of pregnancy. An anesthetic injection is administered to numb the cervix which makes the procedure less painful for the woman, but no anesthetic is administered to the unborn child. Dilating tools are used to stretch open the cervix wide enough to perform the abortion. The doctor uses forceps and other special tools to tear the fetus out of the uterus in pieces. A large vacuum tube is pushed into the uterus and to suction out any remaining pieces. The doctor will then examine the pieces to be sure that the abortion is complete. A D & E abortion is performed in the second trimester (12-24 weeks) and is usually a 2-3 day procedure. At this stage of pregnancy, the fetus' tendons, muscles, and bones are more developed. The cervix has closed more tightly and must be dilated enough to remove the larger fetus. To aid in cervical dilation, laminaria (dried seaweed sticks) are inserted into the cervix. The dilation process can take 1-2 days depending on the size of the fetus. Once the cervix is sufficiently dilated, the laminaria are removed. Forceps are inserted into the uterus to forcibly dismember the fetus. The skull is then crushed and removed. A suction aspiration is then introduced to remove any remaining fetal parts, the placenta and uterine lining. All abortions involve a degree of post-operative bleeding, which is to be expected. Incomplete abortion may occur if fetal tissue is left inside the uterus. Infection is a fairly common problem after an abortion. Although it is easily treated with antibiotics, the infection can result in impaired fertility. Cervical tearing can occur as a result of the dilating process, which may require stitches. A less common but more serious complication is perforation of the uterine wall; this could require surgical repair in a hospital, depending on the severity. In rare cases, abortion patients may experience a major complication, such as a life-threatening pelvic infection, hemorrhage requiring a blood transfusion, uterine rupture, or unintended major surgery. Long-term health risks may include increased risk of miscarriage for future pregnancies. Because late abortion is physically painful and often emotionally distressing, many women elect to have general anesthesia for the procedure. Potential anesthetic complications include severe hemorrhage, convulsion, cardiac arrest, and death.

However, according to Einstein's theory of General Relativity, the speed of light appears to vary with the intensity of the gravitational field. But 1400 years ago it was stated in the Quran (Koran, the book of Islam) that angels travel in one day the same distance that the moon travels in 1000 lunar years, that is, 12000 Lunar Orbits / Earth Day.
