Yawning Man
A yawn is a reflex lasting 4-7 seconds, and is characterized by a long inspiratory phase with gradual mouth gaping, followed by a brief climax (or acme) with muscle stretching, and a rapid expiratory phase with muscle relaxation. For fish and birds, this is described as gradual mouth gaping, staying open for at least 3 seconds and subsequently a rapid closure of the mouth. Almost all vertebrate animals, including mammals, birds, reptiles, amphibians, and even fish, experience yawning. The study of yawning is called chasmology. Yawning (oscitation) most often occurs in adults immediately before and after sleep, during tedious activities and as a result of its contagious quality. It is commonly associated with tiredness, stress, sleepiness, boredom, or even hunger. In humans, yawning is often triggered by the perception that others are yawning (for example, seeing a person yawning, or talking to someone on the phone who is yawning). This is a typical example of positive feed ...

Princeton University Press
Princeton University Press is an independent publisher with close connections to Princeton University. Its mission is to disseminate scholarship within academia and society at large. The press was founded by Whitney Darrow, with the financial support of Charles Scribner, as a printing press to serve the Princeton community in 1905. Its distinctive building was constructed in 1911 on William Street in Princeton. Its first book was a new 1912 edition of John Witherspoon's ''Lectures on Moral Philosophy.'' History Princeton University Press was founded in 1905 by a recent Princeton graduate, Whitney Darrow, with financial support from another Princetonian, Charles Scribner II. Darrow and Scribner purchased the equipment and assumed the operations of two already existing local publishers, that of the ''Princeton Alumni Weekly'' and the Princeton Press. The new press printed both local newspapers, university documents, ''The Daily Princetonian'', and later added book publishing to it ...

Fetal Yawning 4D Ultrasound Ecografia 4D Dr
A fetus or foetus (; plural fetuses, feti, foetuses, or foeti) is the unborn offspring that develops from an animal embryo. Following embryonic development the fetal stage of development takes place. In human prenatal development, fetal development begins from the ninth week after fertilization (or eleventh week gestational age) and continues until birth. Prenatal development is a continuum, with no clear defining feature distinguishing an embryo from a fetus. However, a fetus is characterized by the presence of all the major body organs, though they will not yet be fully developed and functional and some not yet situated in their final anatomical location. Etymology The word ''fetus'' (plural ''fetuses'' or '' feti'') is related to the Latin '' fētus'' ("offspring", "bringing forth", "hatching of young") and the Greek "φυτώ" to plant. The word "fetus" was used by Ovid in Metamorphoses, book 1, line 104. The predominant British, Irish, and Commonwealth spelling is ''fo ...

Chaos (mythology)
Chaos ( grc, χάος, kháos) is the mythological void state preceding the creation of the universe (the cosmos) in Greek creation myths. In Christian theology, the same term is used to refer to the gap or the abyss created by the separation of heaven and earth. Etymology Greek ''kháos'' () means 'emptiness, vast void, chasm, abyss', related to the verbs ''kháskō'' () and ''khaínō'' () 'gape, be wide open', from Proto-Indo-European ', cognate to Old English ''geanian'', 'to gape', whence English ''yawn''. It may also mean space, the expanse of air, the nether abyss or infinite darkness.Lidell-Scott, ''A Greek–English Lexiconchaos/ref> Pherecydes of Syros (fl. 6th century BC) interprets ''chaos'' as water, like something formless that can be differentiated. ''Chaoskampf'' The motif of ''Chaoskampf'' (; ) is ubiquitous in myth and legend, depicting a battle of a culture hero deity with a ''chaos monster'', often in the shape of a serpent or dragon. Parallel concepts ...

Chasm
In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Typical rift features are a central linear downfaulted depression, called a graben, or more commonly a half-graben with normal faulting and rift-flank uplifts mainly on one side. Where rifts remain above sea level they form a rift valley, which may be filled by water forming a rift lake. The axis of the rift area may contain volcanic rocks, and active volcanism is a part of many, but not all, active rift systems. Major rifts occur along the central axis of most mid-ocean ridges, where new oceanic crust and lithosphere is created along a divergent boundary between two tectonic plates. ''Failed rifts'' are the result of continental rifting that failed to continue to the point of break-up. Typically the transition from rifting to spreading develops at a triple junction where three converging rifts meet over a hotspot. Two of these evolve to the point ...

Ginnungagap
In Norse mythology, Ginnungagap (old Norse: ; "gaping abyss", "yawning void") is the primordial void mentioned in the Gylfaginning, the Eddaic text recording Norse cosmogony. Etymology ''Ginnunga-'' is usually interpreted as deriving from a verb meaning "gape" or "yawn", but no such word occurs in Old Norse except in verse 3 of the Eddic poem " Vǫluspá", "gap var ginnunga", which may be a play on the term. In her edition of the poem, Ursula Dronke suggested it was borrowed from Old High German ''ginunga'', as the term Múspell is believed to have been borrowed from Old High German. An alternative etymology links the ''ginn-'' prefix with that found in terms with a sacral meaning, such as ''ginn-heilagr'', ''ginn-regin'' (both referring to the gods) and ''ginn-runa'' (referring to the runes), thus interpreting ''Ginnungagap'' as signifying a "magical (and creative) power-filled space". Creation Ginnungagap appears as the primordial void in the Norse creation account. The ''Gy ...

PIE Root
The roots of the reconstructed Proto-Indo-European language (PIE) are basic parts of words that carry a lexical meaning, so-called morphemes. PIE roots usually have verbal meaning like "to eat" or "to run". Roots never occurred alone in the language. Complete inflected verbs, nouns, and adjectives were formed by adding further morphemes to a root and potentially changing the root's vowel in a process called ablaut. A root consists of a central vowel that is preceded and followed by at least one consonant each. A number of rules have been determined that specify which consonants can occur together, and in which order. The modern understanding of these rules is that the consonants with the highest sonority (') are nearest to the vowel, and the ones with the lowest sonority such as plosives are furthest away. There are some exceptions to these rules such as thorn clusters. Sometimes new roots were created in PIE or its early descendants by various processes such as root extension ...
