Main stem

In hydrology, a main stem is "the primary downstream segment of a river, as contrasted to its tributaries". Another common term for the main stem, the final large channel of a riverine system, is the trunk. Water enters the main stem from the river's drainage basin, the land area through which the main stem and its tributaries flow. A drainage basin may also be referred to as a watershed or catchment.

Hydrological classification systems assign numbers to tributaries and main stems within a drainage basin. In the Strahler number, a modification of a system devised by Robert E. Horton in 1945, channels with no tributaries are called "first-order" streams. When two first-order streams meet, they are said to form a second-order stream; when two second-order streams meet, they form a third-order stream, and so on. In the Horton system, the entire main stem of a drainage basin was assigned the highest number in that basin. However, in the Strahler system, adopted in 1957, only that part of the main stem below the tributary of the next highest rank gets the highest number.

Main (English cricketer)

Main (full name and dates of birth and death unknown) was an English cricketer. Main's batting style is assumed to be left-handed.

Main made his first-class debut for Middlesex against the Marylebone Cricket Club at Lord's in 1830, with him making a further first-class appearance for the county against the same opposition in that year. In 1833, he made a third appearance in first-class cricket, this time for a team of left-handed players against the Marylebone Cricket Club at Lord's Cricket Ground. Main scored a total of 32 runs in this three matches, averaging 8.00, with a high score of 17.

Main (band)

Main were a British ambient band formed in 1991 by the guitarists Robert Hampson and Scott Dowson, the former members of Loop. They combined ambient sound with layers of electric guitars and dark, foreboding emotional overtones. In 2006, Hampson announced that Main had effectively been disbanded in favour of his solo work.

In October 2010, Hampson announced that he would be reactivating Main, and that along with his solo acousmatic work, he would start performing and recording in a more collaborative process with other sound artists.

In 2011, the German composer Stephan Mathieu joined Hampson for a current incarnation of Main.

Stem

Stem may refer to:

Stem (ship)

The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. The stem is often found on wooden boats or ships, but not exclusively. The stem is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull.

Styles

There are two styles of stems: plumb and raked. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb." If it is inclined at an angle to the waterline it is "raked." (E.g., "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.")

Stemhead

Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On smaller vessels, this might be a simple wood carving (ornamental) or cleat (functional). On large wooden ships, figureheads can be attached to the upper end of the stem.

Word stem

In linguistics, a stem is a part of a word. The term is used with slightly different meanings.

In one usage, a stem is a form to which affixes can be attached. Thus, in this usage, the English word friendships contains the stem friend, to which the derivational suffix -ship is attached to form a new stem friendship, to which the inflectional suffix -s is attached. In a variant of this usage, the root of the word (in the example, friend) is not counted as a stem.

In a slightly different usage, which is adopted in the remainder of this article, a word has a single stem, namely the part of the word that is common to all its inflected variants. Thus, in this usage, all derivational affixes are part of the stem. For example, the stem of friendships is friendship, to which the inflectional suffix -s is attached.

Stems may be a root, e.g. run, or they may be morphologically complex, as in compound words (e.g. the compound nouns meat ball or bottle opener) or words with derivational morphemes (e.g. the derived verbs black-en or standard-ize). Hence, the stem of the complex English noun photographer is photo·graph·er, but not photo. For another example, the root of the English verb form destabilized is stabil-, a form of stable that does not occur alone; the stem is de·stabil·ize, which includes the derivational affixes de- and -ize, but not the inflectional past tense suffix -(e)d. That is, a stem is that part of a word that inflectional affixes attach to.
