Chevron Corporation
Chevron Corporation is an American multinational energy corporation. The second-largest direct descendant of Standard Oil, and originally known as the Standard Oil Company of California (shortened to Socal or CalSo), it is headquartered in San Ramon, California, and active in more than 180 countries. Chevron is engaged in every aspect of the oil and natural gas industries, including hydrocarbon exploration and production; refining, marketing and transport; chemicals manufacturing and sales; and power generation. Chevron traces its history back to the 1870s. The company grew quickly after the breakup of Standard Oil by acquiring companies and partnering with others, especially Texaco. Socal was one of the Seven Sisters that dominated the global petroleum industry from the mid-1940s to the 1970s. In 1985, Socal merged with the Pittsburgh-based Gulf Oil and rebranded as Chevron; the newly-merged company later merged with Texaco in 2001. Today, Chevron manufactures and sel ...

Chevron (insignia)
A chevron (also spelled cheveron, especially in older documents) is a V-shaped mark or symbol, often inverted. The word is usually used in reference to a kind of fret in architecture, or to a badge or insignia used in military or police uniforms to indicate rank or length of service, or in heraldry and the designs of flags (see flag terminology). Ancient history Appearing on pottery and petrographs throughout the ancient world, the chevron can be considered to be one of the oldest symbols in human history, with V-shaped markings occurring as early as the Neolithic era (6th to 5th millennia BC) as part of the Vinča symbols inventory. The Vinča culture responsible for the symbols appear to have used the chevron as part of a larger proto-writing system rather than any sort of heraldic or decorative use, and are not known to have passed the symbol on to any subsequent cultures.Mäder, Michael: ''Ist die Donauschrift Schrift?''

Chevron (land Form)
A chevron is a wedge-shaped sediment deposit observed on coastlines and continental interiors around the world. The term chevron was originally used independently by Maxwell and Haynes and Hearty and others for large, V-shaped, sub-linear to parabolic landforms in southwestern Egypt and on islands in the eastern, windward Bahamas. General The Egyptian “chevrons” are active, wind-generated dunes, but the “chevrons” in the Bahamas are inactive and have been variously interpreted. The most common interpretation of large, chevron-shaped bed forms is that they are a form of parabolic dune, and that most examples are generated by wind action. Many chevrons can be found in Australia, but others are concentrated around the coastlines of the world. For instance there are chevrons in Hither Hills State Park on Long Island and in Madagascar (such as the Fenambosy Chevron), as well as in interior sites of the United States such as the Palouse region of eastern Washington State, ...

Angle Brackets
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Philip Chevron
Philip Ryan (17 June 1957 – 8 October 2013), professionally known as Philip Chevron, was an Irish singer-songwriter and guitarist and record producer. He was best known as the lead guitarist for the celtic punk band The Pogues and as the frontman for the 1970s punk rock band The Radiators from Space. Upon his death in 2013, Chevron was regarded as one of the most influential figures in Irish punk music. Career Chevron grew up in Santry, a suburb of Dublin. Beginning in the late 1970s, he was lead singer and co-founder of the punk rock group The Radiators from Space, receiving some critical acclaim but little widespread popularity or financial success. Following a temporary breakup of the band in 1981, he lived in London for a while, meeting and befriending Shane MacGowan through time spent working together at a record shop. Following the release of the Pogues' 1984 debut album ''Red Roses For Me'', he was invited to join the band on a short-term basis as cover for banjo pla ...

Chevron Plot
A chevron plot is a way of representing protein folding kinetic data in the presence of varying concentrations of denaturant that disrupts the protein's native tertiary structure. The plot is known as "chevron" plot because of the canonical ''v'', or chevron shape observed when the logarithm of the observed relaxation rate is plotted as a function of the denaturant concentration. In a two-state system, folding and unfolding rates dominate the observed relaxation rates below and above the denaturation midpoint (Cm). This gives rise to the terminology of folding and unfolding arms for the limbs of the chevron. A priori information on the Cm of a protein can be obtained from equilibrium experiments. In fitting to a two-state model, the logarithm of the folding and unfolding rates is assumed to depend linearly on the denaturant concentration, thus resulting in the slopes mf and mu, called the folding and unfolding m-values, respectively (also called the kinetic m-values). The sum o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chevron (geology)
Chevron folds are a structural feature characterized by repeated well behaved folded beds with straight limbs and sharp hinges. Well developed, these folds develop repeated set of v-shaped beds. They develop in response to regional or local compressive stress. Inter-limb angles are generally 60 degrees or less. Chevron folding preferentially occurs when the bedding regularly alternates between contrasting competences. Turbidites, characterized by alternating high-competence sandstones and low-competence shales, provide the typical geological setting for chevron folds to occur. Perpetuation of the fold structure is not geometrically limited. Given a proper stratigraphy, chevrons can persist almost indefinitely. Fold process In response to compressional stress, geological beds fold in order to minimize dissipation of energy. Given an unconstrained bed, folding does so by correspondingly minimizing bending and thus develops a sinusoidal geometry. In a stratigraphic sequence, b ...

Chevron (anatomy)
A haemal arch also known as a chevron, is a bony arch on the ventral side of a tail vertebra of a vertebrate. The canal formed by the space between the arch and the vertebral body is the haemal canal. A spinous ventral process emerging from the haemal arch is referred to as the haemal spine. Blood vessels to and from the tail run through the arch. In reptiles, the caudofemoralis longus muscle, one of the main muscles involved in locomotion, attaches to the lateral sides of the haemal arches. In 1956, Alfred Sherwood Romer hypothesized that the position of the first haemal arch was sexually dimorphic in crocodilians and dinosaurs. However, subsequent research established that the size and position of the first haemal arch was not sexually dimorphic in crocodilians and found no evidence of significant variation in tyrannosaurid dinosaurs, indicating that haemal arches could not be used to distinguish between sexes after all. Haemal arches play an important role in the taxonomy of sa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Chevron
''The Chevron'' was the official newspaper published by the Federation of Students at the University of Waterloo (in the city of Waterloo in Ontario, Canada) for approximately two decades. Originally the official newspaper of the Federation of Students was ''The Coryphaeus''. The paper was renamed ''The Chevron'' in 1966. The paper was distributed on campus free of charge. Loses status as the students' official paper By 1976 friction had developed between the Federation of Students and the staff of ''The Chevron''. In 1976 the Federation locked the paper's staff out of its offices. In response, staff members who had asked to be admitted to retrieve personal possessions refused to leave, and occupied the offices for several months. On August 22, 1977, Frank Epp, the President of Conrad Grebel College Conrad Grebel University College is a university college affiliated with the University of Waterloo in Waterloo, Ontario, Canada.

Guillemet
Guillemets (, also , , ) are a pair of punctuation marks in the form of sideways double chevrons, and , used as quotation marks in a number of languages. In some of these languages "single" guillemets, and , are used for a quotation inside another quotation. Guillemets are not conventionally used in the English language. Terminology Guillemets may also be called angle, Latin, Castilian, Spanish, or French quotes / quotation marks. ''Guillemet'' is a diminutive of the French name ', apparently after the French printer and punchcutter Guillaume Le Bé (1525–1598), though he did not invent the symbols: they first appear in a 1527 book printed by Josse Bade. Some languages derive their word for guillemets analogously: In Adobe Systems font software, its file format specifications, and in all fonts derived from these that contain the characters, the glyph names are incorrectly spelled and (a malapropism: guillemot is actually a species of seabird).
