8 September. Observations from space Observatory NASA's SDO (Solar Dynamics Observatory) show that powerful explosive processes on the Sun — solar flare — bring to the boundary of earth's atmosphere more than three times more energy than previously thought, say U.S. scientists.
Solar flares are called powerful processes of energy release in the Solar atmosphere in the form of optical, ultraviolet, x-rays and gamma rays, protons and electrons of high energies, emission of plasma. Charged particles reaching the Earth, can «kill» electronics spacecraft, cause disturbances Read more [...]
on January 28. Powerful x-ray flares that occurred on Saturday night, led to a sharp increase in the flow of charged particles in near-earth space that could endanger the spacecraft, told RIA Novosti head of the center for forecasting space weather Institute of terrestrial magnetism, ionosphere and radiowave propagation (IZMIRAN) Sergey Gaydash.
According to the Center for space weather National oceanic control for atmospheric research, USA (NOAA), on Friday at 18:37 GMT (22:37 GMT) occurred on the Sun x-ray class x2. Its source was active region 1402, which had previously been the source of Read more [...]
on July 13. Powerful ejection of plasma on the Sun that occurred on Thursday, may cause a surge of geomagnetic disturbances on the Earth on Saturday, July 14, warn specialists of the laboratory of space weather prediction NASA (Space Weather Lab).
The outbreak in Thursday on the visible side of the Sun, applies power to the maximum category of x-ray radiation — class X. Such outbreaks result from «short circuits» — reconnection of the lines of force of the solar magnetic field. In the released huge amounts of energy and there is an x-ray flash, which is often Read more [...]
NASA Space Telescope captures a picture of the two new species rather strange black holes, which are located in distant spiral galaxy, which are extremely bright at X-ray spectrum of the electromagnetic field.X-ray Space Observatory NuStar (NASA) said bright black holes during galaxy observations Caldwell 5, at a distance of 7 million light-years from Earth in the constellation of Camelopardalis.
Black holes are presented in a picture in a purple color, superimposed on the picture in the same galaxy in the optical range of the electromagnetic field produced by the telescope NuSTAR. These objects Read more [...]
Many ultra bright extragalactic X-ray flares usually associated with black holes, in fact may be something quite different ...In November 2011, the ISS has registered a super-bright X-ray flares in the Small Magellanic Cloud galaxy. It lasted 92 minutes and was very unusual. It is believed that the source of this type of X-ray radiation can be vicinity of black holes, where the light material heated by accretion disks.One flash to prevent burn due BH: X-ray emission from accretion disks gives huge temperature steadily registrable devices. And this time the temperature was too low. Fortunately, Read more [...]
photo: Sun formed one of the largest active regions this year On the invisible side of the sun there was not yet visible from Earth's active area. It will go into the field of view of the Earth 10? July 11 and will remain until 24? July 25. Area can lead to the most significant recent increase X-ray background in Earth orbit.One of the biggest of the year active solar regions in the coming days, will go into the field of view of the Earth. As the laboratory X-ray astronomy of the Sun LPI, most likely it will get in the directory until NOAA free number 1087.The area is currently located on Read more [...]
Cholecystography - A method of X-ray Gallbladder by contrast. Before cholecystography produce panoramic radiograph of the right half of the abdominal cavity. For 12-15 hours before the patient takes bilitrast cholecystography or other contrast media, washed down with sweet tea. The night before and 2 hours prior to the study of patients with enemas cleanse the bowel. After radiographic produce multiple images of the gallbladder in different projections in the vertical and horizontal test. Then the patient eats a special breakfast (egg yolks, butter) and he produced several more shots at intervals Read more [...]

X-rays of the urological patient begins radiography of the urinary tract. In some cases, based on a review picture can make a diagnosis. The use of X-ray methods without prior survey picture can lead to diagnostic error because shadow contrast medium can be taken as shadow calculus, etc. This overview radiograph (typically 30 X 40 cm) can detect changes in the lumbar spine, ribs, pelvis and upper third of the thigh. Changes in the skeletal system may explain the pain that had previously been regarded as a sign of kidney disease. On the survey picture can be observed psoas shadow. The disappearance Read more [...]
X-ray examination to detect abnormalities in the esophagus is paramount. However, the definite diagnosis of the disease is based on a comparison of radiological findings with clinical disease data esophagoscopy, histology taken at biopsy material, radioisotope diagnostic cytology detachable lining of the esophagus. X-ray examination is also important to assess the results of the operation on the esophagus and radiation therapy of malignant tumors. Contraindications to the X-ray study of the esophagus is almost there. You can not produce it only when knowingly violating the integrity of the Read more [...]
X-ray examination should be applied in all cases of acute and especially chronic arthritis, and in most cases, it helps to distinguish them from other joint diseases. X-ray semiotics is an objective criterion for the differential diagnosis of specific (tuberculosis, Brucella, etc.) arthritis of the so-called non-specific A. (with mandatory registration of clinical picture). It reflects, though incomplete, pathologic changes in the bone and cartilage cells joints.
A radiological symptoms appear later in the initial clinical signs. Important for the X-ray has a record duration of the disease, Read more [...]
X-ray diagnosis of aneurysm of the heart based on data from X-ray, X-ray, and roentgenokymograph elektrokimografii. Diagnostic difficulties arise in the heart of the small size of the aneurysm, and the aneurysm apex. The latter can be identified with a deep breath or inflating the stomach. Important, but not common signs of A. p. is semi-oval, smoothly contoured protrusion on the contour of the heart with the "notch" in the upper and lower boundaries (Fig. 2 and 3). Often there is a disproportionate increase in the diameter of the heart to the left (Fig. 4), sometimes - the rectangular Read more [...]
