Coelolepidae is an extinct family of thelodont vertebrate agnathans that lived during the Silurian. [1]
The German language is a West Germanic language mainly spoken in Central Europe. It is the most widely spoken and official or co-official language in Germany, Austria, Switzerland, Liechtenstein, and the Italian province of South Tyrol. It is also a co-official language of Luxembourg, Belgium and parts of southwestern Poland, as well as a national language in Namibia. German is most similar to other languages within the West Germanic language branch, including Afrikaans, Dutch, English, the Frisian languages, Low German, Luxembourgish, Scots, and Yiddish. It also contains close similarities in vocabulary to some languages in the North Germanic group, such as Danish, Norwegian, and Swedish. German is the second most widely spoken Germanic language after English.
The Stefan–Boltzmann law describes the power radiated from a black body in terms of its temperature. Specifically, the Stefan–Boltzmann law states that the total energy radiated per unit surface area of a black body across all wavelengths per unit time is directly proportional to the fourth power of the black body's thermodynamic temperature T:
The Van der Waals radius, rw, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom. It is named after Johannes Diderik van der Waals, winner of the 1910 Nobel Prize in Physics, as he was the first to recognise that atoms were not simply points and to demonstrate the physical consequences of their size through the Van der Waals equation of state.
In molecular physics, the Van der Waals force, named after Dutch physicist Johannes Diderik van der Waals, is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The Van der Waals force quickly vanishes at longer distances between interacting molecules.
In chemistry and thermodynamics, the Van der Waals equation is an equation of state that generalizes the ideal gas law based on plausible reasons that real gases do not act ideally. The ideal gas law treats gas molecules as point particles that interact with their containers but not each other, meaning they neither take up space nor change kinetic energy during collisions. The ideal gas law states that volume (V) occupied by n moles of any gas has a pressure (P) at temperature (T) in kelvins given by the following relationship, where R is the gas constant:
In physics and relativity, time dilation is the difference in the elapsed time as measured by two clocks. It is either due to a relative velocity between them or to a difference in gravitational potential between their locations. When unspecified, "time dilation" usually refers to the effect due to velocity.
The Felinae are a subfamily of the family Felidae. This subfamily comprises the small cats having a bony hyoid, because of which they are able to purr but not roar.

Termatosaurus is a genus of archosaur known from several specimens spanning two species. Its remains come from the Upper Triassic and was once thought to have survived until the Early Jurassic, but the Jurassic remains were redescribed as plesiosaur remains. It has only been found in France, England, Germany and Switzerland. and two species are known of this animal: the type species, Termatosaurus albertii, named by Meyer and T. Plieninger in 1844; and T. crocodilinus, by Quenstedt (1858). It is very obscure and apparently considered to be dubious.

Van der Veen Ice Stream, formerly Ice Stream B1, is a large southeastern tributary to the Whillans Ice Stream in Marie Byrd Land, Antarctica. Named by Advisory Committee on Antarctic Names (US-ACAN) after Cornelis J. "Kees" van der Veen, Byrd Polar Research Center and Departments of Geological Sciences and Geography, Ohio State University; glacial theoretician and collaborator with Ian Whillans, 1986–2001, in many seminal reports on the dynamics of the West Antarctic Ice Sheet, including former Ice Stream B, now Whillans Ice Stream.
Acalissus or Akalissos was a town of ancient Lycia, an early bishopric, and remains a titular see of the Roman Catholic Church. Coins were minted at Acalissus, some of which are housed at numismatic collections.
Arneae or Arneai was a small city of ancient Lycia mentioned by Capito in his Isaurica. It is located near Ernes, in the interior of Lycia where archaeological remains have been found.
Mastaura was a town in ancient Lycia.
Claneus or Klaneos or Klaneous was an ancient city and bishopric in Asia Minor, which remains a Latin Catholic titular see.
Teimiussa, also spelt Teimioussa or Timiussa, also known as Tristomon, was a port town of ancient Lycia, near the ancient settlement Tyberissus. The name is not attested in history, but is derived from epigraphic and other evidence. This combination of harbor and inland location is the focus of archaeological exploration. Among the finds are ancient tombs.
