  1. X-Ray Specs (comic strip)

    Unreferenced date December 2009 X Ray Specs was a comic strip illustrated by Mike Lacey that appeared in the first issue of the British comic Monster Fun on June 14, 1975. Premise X Ray Specs followed the adventures of a boy called Ray and his square shaped spectacles, which were lent to him by I.Squint, the optician. These spectacles gave Ray x ray vision with which he could see through everything. Ray could adjust the power of this vision at will it could range from a view under people s clothes such as for spotting stolen goods from under a man s jacket , to skeletons and walls. Ray later discovered that if he turned the spectacles around and looked through the front of the lenses, he could see a living person from his skeleton a kind of reverse x ray with the added dimension of time. In issues 15 September 20, 1975 and 20 October 25, 1975 , Ray was the cover star of the comic, and the strip was retained in Buster comic Buster s first issue on November 6, 1976. History Becoming the cover star for a short period in 1988, X Ray Specs continued inside Buster until the comic itself finished, despite becoming a reprint in the 1990s with all other Buster strips. Ray s last appearance was on the last page of the final issue at the beginning of 2000 as part of How It All Ends drawn by Jack Edward Oliver , a page showing what eventually happened to most of Buster s characters. In this, I.Squint was seen outside his optician shop snatching the spectacles back from Ray, saying that he only lent Ray the spectacles in 1975, and that he didn t say he could keep them. This is at odds, however, with a strip in a Monster Fun annual, in which Ray breaks his specs on Christmas Eve while looking for his present, and finds out the next day that his present is a new pair of specs from I.Squint.

  1. X-ray background

    The observed X ray background is thought to result from, at the soft end below 0.3 keV , Galactic X ray emission the galactic X ray background , and, at the hard end above 0.3keV , from a combination of many unresolved X ray sources outside of the Milky Way the cosmic X ray background . The galactic X ray background is produced largely by emission from hot gas in the Local Bubble within 100 parsec s of the Sun . Deep surveys with X ray telescopes, such as the Chandra X ray Observatory , have demonstrated that around 80 of the cosmic X ray background is due to resolved extra galactic X ray sources, the bulk of which are unobscured type 1 and obscured type 2 active galactic nuclei AGN .

  1. Characteristic x-ray

    Cleanup date August 2008 Lead rewrite date September 2009 A high energy electron interacts with a bound electron in an atom and ejects it. The incident electron is scattered and the target electron gets displaced from its shell. The incident electron energy must exceed the binding energy of the electron to eject it. After the electron has been ejected the atom is left with a vacant energy level . This vacant energy level if it occurs in the inner electron levels is called a core hole. This vacancy is subsequently filled by an electron from a higher energy level with the emission of a characteristic x ray photon. The characteristic x ray photon has an energy that corresponds exactly to the difference in energy between the energy level that is vacant and the energy level from which an electron falls. The x ray energy is characteristic of the atom that had the core hole and can be used to identify the atom. This is used in various techniques, including X ray fluorescence spectroscopy , Energy dispersive X ray spectroscopy and Wavelength dispersive X ray spectroscopy . These are used in mineral analysis and elsewhere. The characteristic x ray can be immediately reabsorbed by an electron in the same atom and instead the energy of the characteristic x ray is given entirely to this electron which is called an Auger electron . This is like an internal photo electric effect that occurs after the initial photo electric effect.

It is sometimes abbreviated to AXR, or kidneys, ureters, and bladder KUB for kidneys , ureters , and urinary bladder . Diagnostic Tool The abdominal x ray is a test that can be carried out quickly and easily in an emergency department. The test can help diagnose some abdominal conditions. It is not a useful investigation for most abdominal conditions. Small and large bowel obstructions, volvulus and malrotations can be diagnosed by AXR. Renal, urethral and bladder stones can sometimes be identified on plain x ray, although it is usual now to use CT as a first line investigation to confirm clinical suspicion. Gallstones are sometimes noted on x ray, although ultrasound is the more usual imaging modality used when clinically suspected. Plain abdominal radiography is not usually helpful in diagnosis of appendicitis. Technical Parameters An abdominal x ray is usually taken with the patient lying in a supine position . Other views include upright, decubitus, lateral, and prone. Coverage on the x ray should include from the top of the Liver or Thoracic diaphragm diaphragm to the pubic symphysis . The abdominal organs included on the xray are the liver , spleen , stomach , intestines , pancreas , kidneys , and urinary bladder bladder .

  1. X-ray filter

    An X ray filter is a device to block or filter out some or all wavelengths in the X ray spectrum. X ray filters are used to block low energy X rays during medical x ray imaging. Low energy X rays are more likely to be absorbed by the patient s soft tissues. This causes non stochasic radioactive effects, and does not contribute to image quality. X ray filters are used in X ray crystallography , where crystalline lattice spacings can be determined using Bragg diffraction . The filters allow only a single X ray wavelength to penetrate through to a target crystal, allowing the resulting scattering to determine the diffraction distance. Various elemental effects Results Using a Mo X Ray generator Zirconium Absorbs Bremsstrahlung & K Beta . br Iron Absorbs the entire spectra. br Molybdenum Absorbs Bremsstrahlung Leaving K Beta & K Alpha . br Aluminium Pinches Bremsstrahlung & Removes 3rd Generation peaks. br Silver Same as Aluminium, But to greater extent. br Indium Same as Iron, But to lesser extent. br Copper Same as Aluminium, Leaving only 1st Generation Peaks. Bremmstrahlung pinching is due to the atomic mass. The denser the atom, the higher the X Ray Absorption. Only the higher energy X Rays pass through the filter, appearing as if the bremmstrahlung continuum had been pinched. In this case, Mo appears to leave K Alpha and K Beta alone while absorbing the Bremsstrahlung. This is due to Mo absorbing all of the spectra s energy, but in doing so produces the same characteristic peaks as generated by the target.

Springer, 1999 . ref ref M.Tolan, X Ray Scattering from Soft Matter Thin Films , Springer, 1999 ref It is related to the complementary techniques of neutron reflectometry and ellipsometry . The basic idea behind the technique is to reflect a beam of x ray s from a flat surface and to then measure the intensity of x rays reflected in the specular direction reflected angle equal to incident angle . If the interface is not perfectly sharp and smooth then the reflected intensity will deviate from that predicted by the law of Fresnel reflectivity . The deviations can then be analyzed to obtain the density profile of the interface normal to the surface. The technique appears to have first been applied to x rays by Professor Lyman G.

  1. Be X-ray binaries

    Refimprove date September 2009 Be X ray binaries BeXRB s are a class of high mass X ray binaries that consist of a Be star and a neutron star . The neutron star is usually in a wide highly elliptical orbit around the Be star. The Be stellar wind forms a disk confined to a plane often different from the orbital plane of the neutron star. When the neutron star passes through the Be disk, it accretes plenty of gas in a short time. As the gas falls onto the neutron star, a bright flare in hard X ray s is seen. LSI 61 303 LS I 61 303 LSI 61 303 is a periodic, radio emitting binary system that is also the gamma ray source, CG135 01. ref name Taylor cite journal author Taylor AR, Young G, Peracaula M, Kenny HT, Gregory PC title An X ray outburst from the radio emitting X ray binary LSI 61 303 journal Astron Astrophys. year 1996 volume 305 pages 817 24 bibcode 1996A&A...305..817T ref Using the ROSAT and VLA observatories, an X ray outburst with an 10 d duration was detected. ref name Taylor LSI 61 303 is a variable radio source characterized by periodic, non thermal radio outbursts with a period of 26.496 d. ref name Taylor The 26.5 d period has been attributed to the eccentric orbital motion of a compact object, probably a neutron star, around a rapidly rotating B0 Ve star, with a T sub eff sub 26,000 K and luminosity of 10 sup 31 sup watt s 10 sup 38 sup erg s sup 1 sup . ref name Taylor ... name Taylor Of the 20 or so members of the Be X ray binary systems, as of 1996, only X Per and LSI 61 303 have X ray outbursts of much higher luminosity and harder spectrum kT energy kT   10 20 keV ... high mass X ray binaries such as SS 433 , Cygnus X 3 Cyg X 3 and Circinus X 1 Cir X 1 . ref name Taylor References reflist 2 DEFAULTSORT Be X Ray Binaries Category Binary stars Category X ray binaries Be X ray binaries Category Be stars Be X ray binaries star system stub pt Bin rio emissor de raio X Be ...   more details
