Sulfonic acid
In organic chemistry, sulfonic acid (or sulphonic acid) refers to a member of the class of organosulfur compounds with the general formula R−S(=O)2−OH, where R is an organic alkyl or aryl group and the S(=O)2(OH) group a sulfonyl hydroxide.  A sulfonic acid can be thought of as sulfuric acid with one hydroxyl group replaced by an organic substituent. The parent compound (with the organic substituent replaced by hydrogen) is the parent sulfonic acid, HS(=O)2(OH), a tautomer of sulfurous acid, S(=O)(OH)2. Salts or esters of sulfonic acids are called sulfonates.

Parent structure
In chemistry, a parent structure is the structure of an unadorned ion or molecule from which derivatives can be visualized.  Parent structures underpin systematic nomenclature and facilitate classification. Fundamental parent structures have one or no functional groups and often have various types of symmetry. Benzene (C6H6) is a chemical itself consisting of a hexagonal ring of carbon atoms with a hydrogen atom attached to each, and is the parent of many derivatives that have substituent atoms or groups replacing one or more of the hydrogens.  Some parents are rare or nonexistent themselves, as in the case of porphine, though many simple and complex derivatives are known.

Benzene and derivatives

Benzene is the parent.

Toluene is a derivative of benzene.

Porphyrins

Porphine is the parent of porphyrins.

Protoporphyrin IX is a natural derivative of the parent porphine.

Octaethylporphyrin is a synthetic derivative of the parent porphine.

Intended for light trucks and commercials, tractors, and industrial usage, the engine was available in either high speed and low speed designs, in two different displacements. The name means "Oil Engine", followed by the displacement in cubic inches. It was built from 1961 until the late 1960s.

Operation of bus and light rail service is contracted to Metro Transit. Other services include paratransit and a network of shared-use paths.

Shared-use path
A shared-use path, mixed-use path or multi-use pathway is a path which is "designed to accommodate the movement of pedestrians and cyclists". Examples of shared-use paths include sidewalks designated as shared-use, bridleways and rail trails. A shared-use path typically has a surface that is asphalt, concrete or firmly packed crushed aggregate. Shared-use paths differ from cycle tracks and cycle paths in that shared-use paths are designed to include pedestrians even if the primary anticipated users are cyclists.

The path may also permit other users such as inline skating. Contrastingly, motorcycles and mopeds are normally prohibited. Shared-use paths sometimes provide different lanes for users who travel at different speeds to prevent conflicts between user groups on high-use trails. Shared-use paths are criticised for creating conflict between different users. The UK's Department for Transport deprecates this kind of route in denser urban environments.

Bermudian English
Bermudian English is a regional dialect of English found in Bermuda, a British overseas territory in the North Atlantic. Standard English is used in professional settings and in writing, while vernacular Bermudian English is spoken on more casual occasions.  The Bermudian dialect began to develop following settlement in the early 17th century and retains traits of Elizabethan English. Bermudian Creole is also spoken in Bermuda, especially among younger Bermudians.

Casual observers tend to have difficulty in placing the Bermudian dialect, as it differs from those that are clearly British, American, or Caribbean; they also note that the accent tends to vary between individuals. It is often said to sound American or West Indian to a British ear, and quaintly British to American listeners.

Vernacular
Vernacular is the ordinary, informal, spoken form of a language or dialect, particularly when perceived as having lower social status or less prestige than standard language, which is more codified, institutionally promoted, literary, or formal. More narrowly, any particular variety of a natural language that does not hold a widespread high-status perception, and sometimes even carries social stigma, is also called a vernacular, vernacular dialect, nonstandard dialect, etc. and is typically its speakers' native variety. Regardless of any such stigma, all nonstandard dialects are full-fledged varieties of language with their own consistent grammatical structure, sound system, body of vocabulary, etc.

Uterine contraction
Uterine contractions are muscle contractions of the uterine smooth muscle that can occur at various intensities in both the non-pregnant and pregnant uterine state. The non-pregnant uterus undergoes small, spontaneous contractions in addition to stronger, coordinated contractions during the menstrual cycle and orgasm. Throughout gestation, the uterus enters a state of uterine quiescence due to various neural and hormonal changes. During this state, the uterus undergoes little to no contractions, though spontaneous contractions still occur for the uterine myocyte cells to experience hypertrophy. The pregnant uterus only contracts strongly during orgasms, labour, and in the postpartum stage to return to its natural size.

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth.

The time interval of a gestation is called the gestation period. In obstetrics, gestational age refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks.

The 1992 draft was notable because for the first time since 1958 one team, the Indianapolis Colts, held the first two overall picks, selecting defensive end Steve Emtman and then linebacker Quentin Coryatt. Neither made a major impact in the league, and the 1992 draft in retrospect is considered one of the worst in league history.
