Dewatering (pronounced de-water-ing) is the removal of water from solid material or soil by wet classification, centrifugation, filtration, or similar solid-liquid separation processes, such as removal of residual liquid from a filter cake by a filter press as part of various industrial processes.
High Quality Content by WIKIPEDIA articles! Diablo Canyon Power Plant is an electricity-generating nuclear power plant at Avila Beach in San Luis Obispo County, California. The plant has two Westinghouse-designed 4-loop pressurized-water nuclear reactors operated by Pacific Gas & Electric. The facility is located on about 750 acres (300 ha) in Avila Beach, California. Together, the twin 1,100 MWe reactors produce about 18,000 GW·h of electricity annually, supplying the electrical needs of more than 2.2 million people, sent along the Path 15 500-kV lines that connect to this plant. It was built directly over a geological fault line, and is located near a second fault.

High Quality Content by WIKIPEDIA articles! Differential scanning calorimetry or DSC is a thermoanalytical technique in which the difference in the amount of heat required to increase the temperature of a sample and reference is measured as a function of temperature. Both the sample and reference are maintained at nearly the same temperature throughout the experiment. Generally, the temperature program for a DSC analysis is designed such that the sample holder temperature increases linearly as a function of time. The reference sample should have a well-defined heat capacity over the range of temperatures to be scanned.
High Quality Content by WIKIPEDIA articles! Diffraction topography (short: "topography") is an X-ray imaging technique based on Bragg diffraction. Diffraction topographic images ("topographs") record the intensity profile of a beam of X-rays (or, sometimes, neutrons) diffracted by a crystal. A topograph thus represents a two-dimensional spatial intensity mapping of reflected X-rays, i.e. the spatial fine structure of a Bragg spot. This intensity mapping reflects the distribution of scattering power inside the crystal; topographs therefore reveal the irregularities in a non-ideal crystal lattice. X-ray diffraction topography is one variant of X-ray imaging, making use of diffraction contrast rather than absorption contrast which is...

Digital Image Correlation and Tracking (DIC/DDIT) is an optical method that employs tracking & image registration techniques for accurate 2D and 3D measurements of changes in images. This is often used to measure deformation (engineering), displacement, strain, and optical flow, but it is widely applied in many areas of science and engineering. One very common application is for measuring the motion of an optical mouse.
High Quality Content by WIKIPEDIA articles! Dimension stone is natural stone or rock that has been selected and fabricated (i.e., trimmed, cut, drilled, ground, or other) to specific sizes or shapes. Color, texture and pattern, and surface finish of the stone are also normal requirements. Another important selection criterion is durability: the time measure of the ability of dimension stone to endure and to maintain its essential and distinctive characteristics of strength, resistance to decay, and appearance.

By decreasing or increasing the RMS voltage and, hence, the mean power to the lamp, it is possible to vary the intensity of the light output. Although variable-voltage devices are used for various purposes, the term dimmer is generally reserved for those intended to control light output from resistive incandescent, halogen, and (more recently) compact fluorescent lights (CFLs) and light-emitting diodes (LEDs). More specialized equipment is needed to dim fluorescent, mercury vapor, solid state and other arc lighting.
High Quality Content by WIKIPEDIA articles! The Dinas Powys hill fort is an Iron Age hill fort located in Cwrt-yr-Ala Park, a half-a-mile north of the village of Dinas Powys in Glamorgan, south Wales. It is just one of several thousand hillforts to have been constructed around Britain during the British Iron Age, for reasons that are still debatable. The main fort at Dinas Powys was constructed on the northernmost point of the hill in either the third or 2nd century BCE, with two further constructs, known as the Southern Banks, being built further down on the southern end of the hill in the following 1st century BCE. It appears that occupation at the site ceased during the period of Roman Britain, but was re-inhabited by an Early...
High Quality Content by WIKIPEDIA articles! In electronics, a diode is a two-terminal electronic component with an asymmetric transfer characteristic, with low (ideally zero) resistance to current flow in one direction, and high (ideally infinite) resistance in the other. A semiconductor diode, the most common type today, is a crystalline piece of semiconductor material with a p-n junction connected to two electrical terminals. A vacuum tube diode is a vacuum tube with two electrodes, a plate (anode) and heated cathode.

Dip Pen Nanolithography (DPN) began as a scanning probe lithography technique where an atomic force microscope tip was used to transfer alkane thiolates to a gold surface. This technique allows surface patterning on scales of under 100 nanometers. DPN is the nanotechnology analog of the dip pen (also called the quill pen), where the tip of an atomic force microscope cantilever acts as a "pen," which is coated with a chemical compound or mixture acting as an "ink," and put in contact with a substrate, the "paper."
High Quality Content by WIKIPEDIA articles! Disaster!: A Major Motion Picture Ride...Starring You! is an attraction at Universal Studios Florida. Set on a soundstage of a fictitious movie company, Disaster! Studios, Disaster! is a reinvigorated version of the park`s former Earthquake: The Big One ride which comically illustrates how special effects are filmed for use in movies. The attraction`s climax casts the riders as "extras" for a movie finale scene involving an earthquake in a subway station. Thanks to high-speed editing techniques, the riders get to see their handiwork in the form of a movie trailer that includes film sequences shot throughout the attraction`s pre-show and main ride.
High Quality Content by WIKIPEDIA articles! In materials science, a dislocation is a crystallographic defect, or irregularity, within a crystal structure. The presence of dislocations strongly influences many of the properties of materials. The theory was originally developed by Vito Volterra in 1905, but the term `dislocation` was not coined until later by the late Professor Sir Frederick Charles Frank of the Physics Department at the University of Bristol. Some types of dislocations can be visualized as being caused by the termination of a plane of atoms in the middle of a crystal. In such a case, the surrounding planes are not straight, but they instead bend around the edge of the terminating plane so that the crystal structure is...

A diverging diamond interchange (DDI), also called a double crossover diamond interchange (DCD), is a type of diamond interchange in which the two directions of traffic on the non-freeway road cross to the opposite side on both sides of the bridge at the freeway. It is unusual in that it requires traffic on the freeway overpass (or underpass) to briefly drive on the opposite side of the road from what is customary for the jurisdiction. The diverging diamond interchange was listed by Popular Science magazine as one of the best innovations in 2009 (engineering category) in "Best of What`s New 2009".

Designed by architect Willis G. Hale and built between 1892 and 1894, the building originally functioned as apartments, housing some of Philadelphia`s wealthy residents. Lorraine Apartments is one of the most luxurious and best preserved late 19th century apartment houses in Philadelphia. In 1900 the building became the Lorraine Hotel when the Metropolitan Hotel Company purchased the apartments. Later it would become the first hotel in Philadelphia to be racially integrated under Father Divine.
