Childeric II was the king of Austrasia from 662 and of Neustria and Burgundy from 673 until his death, making him sole King of the Franks for the final two years of his life.
In physics, buoyancy or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column. Similarly, the pressure at the bottom of an object submerged in a fluid is greater than at the top of the object. The pressure difference results in a net upward force on the object. The magnitude of the force is proportional to the pressure difference, and is equivalent to the weight of the fluid that would otherwise occupy the volume of the object, i.e. the displaced fluid.
Archimedes' principle states that the upward buoyant force that is exerted on a body immersed in a fluid, whether fully or partially submerged, is equal to the weight of the fluid that the body displaces and acts in the upward direction at the center of mass of the displaced fluid. Archimedes' principle is a law of physics fundamental to fluid mechanics. It was formulated by Archimedes of Syracuse.
A cèilidh or céilí is a traditional Scottish or Irish social gathering. In its most basic form, it simply means a social visit. In contemporary usage, it usually involves dancing and playing Gaelic folk music, either at a house party or a larger concert at a social hall or other community gathering place.
An internally displaced person (IDP) is someone who is forced to flee his or her home but who remains within his or her country's borders. They are often referred to as refugees, although they do not fall within the legal definitions of a refugee.
Forced displacement or forced immigration is the coerced movement of a person or people away from their home or home region and it often connotes violent coercion. Someone who has experienced forced displacement is a "forced immigrant", a "displaced person" (DP), rarely also a "displacee", or if it is within the same country, an internally displaced person (IDP). In some cases the forced immigrant can also become a refugee, as that term has a specific legal definition. A specific form of forced displacement is population transfer, which is a coherent policy to move unwanted groups, for example, as an attempt at ethnic cleansing. Another form is deportation.
In fluid mechanics, displacement occurs when an object is immersed in a fluid, pushing it out of the way and taking its place. The volume of the fluid displaced can then be measured, and from this, the volume of the immersed object can be deduced.
Rock and roll is a style of popular American music which has spread across the world, including to the North Atlantic island nation of Iceland.
Peter Lewis Kingston Wentz III is an American singer, songwriter and multi-instrumentalist. He is best known for being the bassist, lyricist, and backing vocalist for the American rock band Fall Out Boy. Before Fall Out Boy's inception in 2001, Wentz was a fixture of the Chicago hardcore scene and was the lead vocalist and lyricist for Arma Angelus. During Fall Out Boy's hiatus from 2009 to 2012, Wentz formed the experimental, electropop and dubstep group Black Cards. He owns a record label, DCD2 Records, which has signed bands including Panic! at the Disco and Gym Class Heroes.
Displaced persons camps in post-World War II Europe were camps established after World War II in Germany, Austria, and Italy, primarily for refugees from Eastern Europe and for the former inmates of the Nazi German concentration camps. A "displaced persons camp" is a temporary facility for displaced persons, whether refugees or internally displaced persons. Two years after the end of World War II in Europe, some 850,000 people lived in DP camps across Europe, among them Armenians, Poles, Latvians, Lithuanians, Estonians, Yugoslavs, Jews, Greeks, Russians, Ukrainians and Czechoslovaks.
Sh'erit ha-Pletah is a biblical term used by Jewish refugees who survived the Holocaust to refer to themselves and the communities they formed in postwar Europe following the liberation in the spring of 1945.
A displaced threshold or DTHR is a runway threshold located at a point other than the physical beginning or end of the runway.
Sun Valley Serenade is a 1941 musical film directed by H. Bruce Humberstone and starring Sonja Henie, John Payne, Glenn Miller, Milton Berle, and Lynn Bari. It features the Glenn Miller Orchestra as well as dancing by the Nicholas Brothers and Dorothy Dandridge, performing "Chattanooga Choo Choo", which was nominated for an Academy Award for Best Song, was inducted into the Grammy Hall of Fame in 1996, and was awarded the first Gold Record for sales of 1.2 million.
Nicola is an extinct Athabascan language formerly spoken in the Similkameen and Nicola Countries of British Columbia by the group known to linguists and ethnographers as the Nicola people, although that name in modern usage refers to an alliance of Interior Salishan bands living in the same area. Almost nothing is known of the language. The available material published by Franz Boas required only three pages. What the Nicola called themselves and their language is unknown. The Salishan-speaking Thompson language Indians who absorbed them refer to them as the "the strangers".
A patella fracture is a break of the kneecap. Symptoms include pain, swelling, and bruising to the front of the knee. A person may also be unable to walk. Complications may include injury to the tibia, femur, or knee ligaments.
Displacement chromatography is a chromatography technique in which a sample is placed onto the head of the column and is then displaced by a solute that is more strongly sorbed than the components of the original mixture. The result is that the components are resolved into consecutive “rectangular” zones of highly concentrated pure substances rather than solvent-separated “peaks”. It is primarily a preparative technique; higher product concentration, higher purity, and increased throughput may be obtained compared to other modes of chromatography.
A lingual arch is an orthodontic device which connects two molars in the upper or lower dental arch. The lower lingual arch (LLA) has an archwire adapted to the lingual side of the lower teeth. In the upper arch the archwire is usually connecting the two molars passing through the palatal vault, and is commonly referred as "Transpalatal Arch" (TPA). The TPA was originally described by Robert Goshgarian in 1972. TPAs could possibly be used for maintaining transverse arch widths, anchorage in extraction case, prevent buccal tipping of molars during Burstonian segmented arch mechanics, transverse anchorage and space maintenance.
A headlamp or headlight is a light source affixed to the head for outdoor activities at night or in dark conditions such as caving, orienteering, hiking, skiing, backpacking, camping, mountaineering or mountain biking. Headlamps may also be used in adventure races. Headlamps are often used by workers in underground mining, search and rescue, surgeons, and by other workers who need hands-free lighting.
"Semper Fidelis", written in 1888 by John Philip Sousa, is regarded as the official march of the United States Marine Corps. This piece was one of two composed in response to a request from United States President Chester Arthur for a new piece to be associated with the United States President. The words Semper Fidelis are Latin for "Always Faithful."
