Casselman River
Casselman River The Casselman River is a 56.5-mile-long (90.9 km) tributary of the Youghiogheny River in western Maryland and Pennsylvania in the United States. The Casselman River rises in Garrett County atop the plateau of western Maryland as two branches, the south one east of Meadow Mountain, the north one farther west, between Meadow Mountain and Negro Mountain. The two branches flow northward combining just southwest of Grantsville, Maryland. The river then continues north into Pennsylvania, following a great arc across the Laurel Highlands of Somerset County, Pennsylvania to the community of Confluence, where Laurel Hill Creek joins a few

The river has been used for transportation across the Allegheny Mountains, between the cities of Baltimore and Washington, D.C. in the east and Pittsburgh in the west. Two railroads followed the Casselman River from Meyersdale, Pennsylvania to Confluence. First is the B&O Railroad, running between Baltimore and Pittsburgh, which was completed in 1827, and is currently owned by CSX. Second is the Western Maryland Railway, which ran from Cumberland, Maryland to Connellsville, Pennsylvania. Although the Western Maryland was abandoned in the 1980s, the right-of-way has been converted into the Great Allegheny Passage, a rail trail bicycle

Cassette Scandal Consequences The described events provoked a crisis, with mass protests in Kiev from 15 December 2000 to 9 March 2001. Opposition started a campaign of non-violent resistance called UBK ("Ukraine without Kuchma!"), demanding Kuchma's resignation. Despite economic growth in the country, President Kuchma's public approval ratings fell below 9%. In 2002, the governments of United States and other countries became more deeply involved after one of the recordings revealed the alleged transfer of a sophisticated Ukrainian defence system "Kol'chuha" to Saddam Hussein's Iraq. As a result, Leonid Kuchma was boycotted by Western governments for a time. In particular,

he experienced an offensive diplomatic démarche when visiting the North Atlantic Treaty Organization summit that took place on 21–22 November 2002 in Prague. Breaking the decades-lasting tradition, the list of participating countries was announced in French, not English. As a result Turkey was named after Ukraine, instead of the United Kingdom and United States, thereby avoiding the appearance of Kuchma next to Tony Blair and George W. Bush. Moreover, widely publicized conversations depicted Kuchma as a rude and spiteful person, using bad language and speaking an unusual mixture of Russian and Ukrainian languages. Advocates argue that excessive foul language is the

proof of a deliberate montage of the recordings using extrinsic audio samples. Influenced by all above-mentioned, the President soon became disillusioned with European integration and started to loosen Ukraine's relations with the United States and European Union, critical to his regime. Instead, he boosted integration with Russia, considering the fact that its new leader, Vladimir Putin, was continuously supporting Kuchma and refusing to recognize the allegations. In September 2003, Ukrainian troops joined U.S.-led stabilization forces in Iraq, which is widely perceived as Kuchma's effort to improve relations with the West. Since then, high-level relations were partially restored. Commenting on the scandal and Mel'nychenko's

These locomotives were not equipped with adaptable bogies, so the locomotive numbers 3003 and 3004, which had Iberian gauge bogies, worked the section between Barcelona and the French-Spanish border, while the other three locomotives of this series, which had standard gauge bogies, served the section between the French-Spanish border and Geneva. Already in September 1971, the standard gauge locomotives were replaced by class BB 67400 of SNCF. The broad gauge locomotives were replaced shortly after by class 276 of RENFE. In

One generator car, the RT 212, houses the train chief's office, while the other, the RT 211, is provided with a luggage compartment. The basic composition of the train consisted, in between the two generator cars, of nine carriages RT 201, one bar/kitchen car RT 206 and two dining cars RT 210.

This church also served as the namesake for Seeber's new firm. With the purchase of more land in the quarter of La Boca, the Retiro lot was named Catalinas Norte (North Catalinas), and the La Boca lot, Catalinas Sur.

specially-marked dice representing resources can be rolled up to three times, with the player being able to choose which dice to keep between rolls. After the player stops rolling, they may invest their resources to build roads, knights, settlements, and cities; each of these having differing resource requirements. Roads must extend from a starting point, which the cities and settlements (which must be built in increasing order of point value) must connect. Knights may be used to unlock "resource jokers", which allow the outcome of one die to be set to a specific resource after the dice have been rolled. For

Cathedral of Saint Demetrius
History
Cathedral of Saint Demetrius The Cathedral of Saint Demetrius (Russian Дмитриевский собор) is a cathedral in the ancient Russian city of Vladimir. It was finished in 1197 during the reign of the Grand Prince Vsevolod the Big Nest of Vladimir-Suzdal to the honour of Saint Demetrius of Thessaloniki. Being an important component of the White Monuments of Vladimir and Suzdal, the cathedral belongs to the World Heritage of UNESCO. Currently, the cathedral is a part of the Vladimir-Suzdal open-air museum. History The Cathedral of St. Dmitrii in Vladimir, Russia was built by Vsevolod III in 1193-7. It was one

Architects and artisans from both the east and west resided there are were used in the construction of the church. In addition, Vsevolod’s mother was a Byzantine princess and Vsevolod lived in Constantinople for several years during his childhood. Another source of inspiration may also have been portable carvings such as Byzantine ivories. The carvings consist of animals and plants as well as figures in rows and scenes in the zakomary. Some carvings are also ornamental patterns.

The building was renovated in 1855, 1866, 1906, and 1967, and still retains its architectural integrity, but is in a state of deterioration. It was listed on the Providence Preservation Society 10 Most Endangered Properties List in 2007, 2008 and 2010. Citing dwindling membership and costs associated with upkeep, the diocese closed the church in 2012.

Cattle cycle
Cattle cycle The cattle cycle is the approximately 10-year period in which the number of U.S. beef cattle is alternatively expanded and reduced over several consecutive years in response to perceived changes in profitability by producers. Generally, low prices occur when cattle numbers (or beef supplies) are high, precipitating several years of herd liquidation. As cattle numbers decline, prices gradually begin to rise, causing producers to begin adding cattle to their herds. The cycle is relatively long due to the long period of time it takes between the time a cow-calf operator decides to expand a cow herd to

Causal model
Causal model In philosophy of science, a causal model (or structural causal model) is a conceptual model that describes the causal mechanisms of a system. Causal models can improve study designs by providing clear rules for deciding which independent variables need to be included/controlled for. They can allow some questions to be answered from existing observational data without the need for an interventional study such as a randomized controlled trial. Some interventional studies are inappropriate for ethical or practical reasons, meaning that without a causal model, some hypotheses cannot be tested. Causal models can help with the question of

Hume rejected Aristotle's taxonomy in favor of counterfactuals. At one point, he denied that objects have "powers" that make one a cause and another an effect. Later he adopted "if the first object had not been, the second had never existed" ("but-for" causation). In the late 19th century, the discipline of statistics began to form.

As a positivist, Pearson expunged the notion of causality from much of science as an unprovable special case of association and introduced the correlation coefficient as the metric of association. He wrote, "Force as a cause of motion is exactly the same as a tree god as a cause of growth" and that causation was only a "fetish among the inscrutable arcana of modern science". Pearson founded Biometrika and the Biometrics Lab at University College London, which became the world leader in statistics. In 1908

Hardy and Weinberg solved the problem of trait stability that had led Galton to abandon causality, by resurrecting Mendelian inheritance. In 1921 Wright's path analysis became the theoretical ancestor of causal modeling and causal graphs. He developed this approach while attempting to untangle the relative impacts of heredity, development and environment on guinea pig coat patterns. He backed up his then-heretical claims by showing how such analyses could explain the relationship between guinea pig birth weight, in utero time and litter size. Opposition to these ideas by prominent statisticians led them to be ignored for the following 40 years (except among

One exception was Burks, a student who in 1926 was the first to apply path diagrams to represent a mediating influence (mediator) and to assert that holding a mediator constant induces errors. She may have invented path diagrams independently. In 1923, Neyman introduced the concept of a potential outcome, but his paper was not translated from Polish to English until 1990.

While reading Blalock's work on path diagrams, Duncan remembered a lecture by Ogburn twenty years earlier that mentioned a paper by Wright that in turn mentioned Burks. Sociologists originally called causal models structural equation modeling, but once it became a rote method, it lost its utility, leading some practitioners to reject any relationship to causality. Economists adopted the algebraic part of path analysis, calling it simultaneous equation modeling. However, economists still avoided attributing causal meaning to their equations.

The middle level, Intervention (doing), predicts the effects of deliberate actions, expressed as causal relationships. The highest level, Counterfactuals (imagining), involves constructing a theory of (part of) the world that explains why specific actions have specific effects and what happens in the absence of such actions. Counterfactuals The highest, counterfactual, level involves consideration of an alternate version of a past event. Example: What is the probability that, if a store had doubled the price of floss,

Counterfactuals & Types & Necessary
the toothpaste-purchasing shopper would still have bought it? Answering yes asserts the existence of a causal relationship. Models that can answer counterfactuals allow precise interventions whose consequences can be predicted. At the extreme, such models are accepted as physical laws (as in the laws of physics, e.g., inertia, which says that if force is not applied to a stationary object, it will not move). Types A cause can be necessary, sufficient, contributory or some combination. Necessary For x to be a necessary cause of y, the presence of y must imply the prior occurrence of x. The presence of x,

Sufficient causes For x to be a sufficient cause of y, the presence of x must imply the subsequent occurrence of y. However, another cause z may independently cause y. Thus the presence of y does not require the prior occurrence of x. Contributory causes For x to be a contributory cause of y, the presence of x must increase the likelihood of y.

A causal diagram includes a set of variables (or nodes). Each node is connected by an arrow to one or more other nodes upon which it has a causal influence. An arrowhead delineates the direction of causality, e.g., an arrow connecting variables A and B with the arrowhead at B indicates that a change in A causes a change in B (with an associated probability).

Mendelian randomization Definition: Mendelian randomization uses measured variation in genes of known function to examine the causal effect of a modifiable exposure on disease in observational studies. Because genes vary randomly across populations, presence of a gene typically qualifies as an instrumental variable, implying that in many cases, causality can be quantified using regression on an observational study.

set of manipulations that are available to transform one expression into another, with the general goal of transforming expressions that contain the do operator into expressions that do not. Expressions that do not include the do operator can be estimated from observational data alone, without the need for an experimental intervention, which might be expensive, lengthy or even unethical (e.g., asking subjects to take up smoking). The set of rules is complete (it can be used to derive every true statement in this system). An algorithm can determine whether, for a given model, a solution is computable in polynomial time.

Mediation Direct and indirect (mediated) causes can only be distinguished via conducting counterfactuals. Understanding mediation requires holding the mediator constant while intervening on the direct cause. In the model M mediates X's influence on Y, while X also has an unmediated effect on Y. Thus M is held constant, while do(X) is computed. The Mediation Fallacy instead involves conditioning on the mediator if the mediator and the outcome are confounded, as they are in the above model.

Function
Caveolin 1 Function The scaffolding protein encoded by this gene is the main component of the caveolae plasma membranes found in most cell types. The protein links integrin subunits to the tyrosine kinase FYN, an initiating step in coupling integrins to the Ras-ERK pathway and promoting cell cycle progression. The gene is a tumor suppressor gene candidate and a negative regulator of the Ras-p42/44 MAP kinase cascade. CAV1 and CAV2 are located next to each other on chromosome 7 and express colocalizing proteins that form a stable hetero-oligomeric complex.

Cecilia Johansdotter of Sweden Biography Despite the fact that she was queen for over twenty years, the queen consort of King Canute is one of the most unknown of Swedish queens. Neither her name, her parents or her birth and death years are confirmed. Canute I stated in a letter to Pope Clement III that his bride was the only one who was of sufficiently high status to marry him, which may point to royal connections. Some historians guess that she was the daughter of John, son of King Sverker I of Sweden (d. 1156). The assumption that she carried

the name Cecilia rests on the hypothesis that an annal entry from the 14th century has been twisted. This text states that the mother of Eric the Saint (d. 1160) was called Cecilia, the sister of Ulf Jarl and Kol and the daughter of a king Sven (presumably alluding to Blot-Sweyn). This in turn can be compared with a genealogy that mentions Ubbe (Ulf), Kol and Burislev as the sons of John Sverkersson. Their implied sister Cecilia would then have been the mother of Eric X of Sweden, whose father was Canute I, rather than being the mother of Eric

the Saint. The hypotheses might be strengthened by a 13th-century painting in the church of Dädesjö mentioning the names Canute and (possibly) Cecilia. However, a marriage alliance between the two feuding royal clans of Sverker and Eric is not entirely plausible. A contemporary document shows that she was the sister of another nobleman called Canute, known in an (alleged) lost document as Canute Ulvhildsson. According to an alternative hypothesis, the Queen's brother Canute was the son of an Ingeborg, daughter of Sigvard. These three persons were all donators to Vårfruberga Abbey.

In 1167, seven years later, her husband became King and she was made Queen of Sweden. There is only one story that truly mentions the Queen in more detail. In c. 1190, the Queen was taken ill.

Celestial spheres
Celestial spheres The celestial spheres, or celestial orbs, were the fundamental entities of the cosmological models developed by Plato, Eudoxus, Aristotle, Ptolemy, Copernicus, and others. In these celestial models, the apparent motions of the fixed stars and planets are accounted for by treating them as embedded in rotating spheres made of an aetherial, transparent fifth element (quintessence), like jewels set in orbs. Since it was believed that the fixed stars did not change their positions relative to one another, it was argued that they must be on the surface of a single starry sphere. In modern thought, the orbits of

the planets are viewed as the paths of those planets through mostly empty space. Ancient and medieval thinkers, however, considered the celestial orbs to be thick spheres of rarefied matter nested one within the other, each one in complete contact with the sphere above it and the sphere below. When scholars applied Ptolemy's epicycles, they presumed that each planetary sphere was exactly thick enough to accommodate them. By combining this nested sphere model with astronomical observations, scholars calculated what became generally accepted values at the time for the distances to the Sun (about 4 million miles), to the other planets,

and to the edge of the universe (about 73 million miles). The nested sphere model's distances to the Sun and planets differ significantly from modern measurements of the distances, and the size of the universe is now known to be inconceivably large and continuously expanding. Albert Van Helden has suggested that from about 1250 until the 17th century, virtually all educated Europeans were familiar with the Ptolemaic model of "nesting spheres and the cosmic dimensions derived from it". Even following the adoption of Copernicus's heliocentric model of the universe, new versions of the celestial sphere model were introduced, with the

Mainstream belief in the theory of celestial spheres did not survive the Scientific Revolution. In the early 1600s, Kepler continued to discuss celestial spheres, although he did not consider that the planets were carried by the spheres but held that they moved in elliptical paths described by Kepler's laws of planetary motion. In the late 1600s, Greek and medieval theories concerning the motion of terrestrial and celestial objects were replaced by Newton's law of universal gravitation and Newtonian mechanics, which explain how Kepler's

laws arise from the gravitational attraction between bodies. Early ideas of spheres and circles In Greek antiquity the ideas of celestial spheres and rings first appeared in the cosmology of Anaximander in the early 6th century BC. In his cosmology both the Sun and Moon are circular open vents in tubular rings of fire enclosed in tubes of condensed air; these rings constitute the rims of rotating chariot-like wheels pivoting on the Earth at their centre. The fixed stars are also open vents in such wheel rims, but there are so many such wheels for the stars that their contiguous

rims all together form a continuous spherical shell encompassing the Earth. All these wheel rims had originally been formed out of an original sphere of fire wholly encompassing the Earth, which had disintegrated into many individual rings. Hence, in Anaximanders's cosmogony, in the beginning was the sphere, out of which celestial rings were formed, from some of which the stellar sphere was in turn composed. As viewed from the Earth, the ring of the Sun was highest, that of the Moon was lower, and the sphere of the stars was lowest. Following Anaximander, his pupil Anaximenes (c. 585–528/4) held that the

until they rise again. And unlike Anaximander, he relegated the fixed stars to the region most distant from the Earth. The most enduring feature of Anaximenes' cosmos was its conception of the stars being fixed on a crystal sphere as in a rigid frame, which became a fundamental principle of cosmology down to Copernicus and Kepler. After Anaximenes, Pythagoras, Xenophanes and Parmenides all held that the universe was spherical. And much later in the fourth century BC Plato's Timaeus proposed that the body of the cosmos was made in the most perfect and uniform shape, that of a sphere containing the
