Hospital Massacre (also known as X-Ray, Be My Valentine, Or Else, and Ward 13) is a 1982 American slasher film directed by Boaz Davidson and starring Barbi Benton.Its plot follows a woman who becomes trapped on an empty floor of a hospital, where a murderer posing as a surgeon attempts to kill her.
X-ray diffraction topography is one variant of X-ray imaging, making use of diffraction contrast rather than absorption contrast which is usually used in radiography and computed tomography (CT). Topography is exploited to a lesser extent with neutrons , and is the same concept as dark field imaging in an electron microscope .
Soil formation begins with the chemical and/or physical breakdown of minerals to form the initial material that overlies the bedrock substrate. Biology quickens this by secreting acidic compounds that help break rock apart.
Natural color X-ray photogram of a wine scene. Note the edges of hollow cylinders as compared to the solid candle. William Coolidge explains medical imaging and X-rays.. An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
Engineering applications include nondestructive testing (NDT) of structures and pavements, locating buried structures and utility lines, and studying soils and bedrock. In environmental remediation , GPR is used to define landfills, contaminant plumes, and other remediation sites, while in archaeology it is used for mapping archaeological ...
Two people are dead and another is injured after a Civil Air Patrol plane crashed Saturday in northern Colorado. The Civil Air Patrol, an auxiliary of the U.S. Air Force, said the aircraft -- a ...
For a while, it looked like Duke was on track to be another loss. The Blue Devils came out flat, falling behind 13-2 to open the game. Their defensive effort improved after a Jon Scheyer timeout ...
For imaging surfaces, the penetration of X-rays may be undesirable, in which case a glancing angle geometry may be used such as GISAXS. [2] A typical x-ray CCD is used to record the diffraction pattern. If the sample is rotated about an axis perpendicular to the beam a 3-Dimensional image may be reconstructed. [12]
