Stem Cell
In multicellular organisms, stem cells are undifferentiated or partially differentiated cells that can differentiate into various types of cells and proliferate indefinitely to produce more of the same stem cell. They are the earliest type of cell in a cell lineage. They are found in both embryonic and adult organisms, but they have slightly different properties in each. They are usually distinguished from progenitor cells, which cannot divide indefinitely, and precursor or blast cells, which are usually committed to differentiating into one cell type. In mammals, roughly 50–150 cells make up the inner cell mass during the blastocyst stage of embryonic development, around days 5–14. These have stem-cell capability. '' In vivo'', they eventually differentiate into all of the body's cell types (making them pluripotent). This process starts with the differentiation into the three germ layers – the ectoderm, mesoderm and endoderm – at the gastrulation stage. Howev ...

Die Stem Van Suid-Afrika
Die Stem van Suid-Afrika (, ), also known as "The Call of South Africa" or simply "Die Stem" (), is a former national anthem of South Africa. There are two versions of the song, one in English and the other in Afrikaans, which were in use early on in the Union of South Africa alongside God Save the Queen and as the sole anthem after South Africa became a republic. It was the sole national anthem from 1957 to 1994, and shared co-national anthem status with " God Save the King/Queen" from 1938 to 1957. After the end of apartheid in the early 1990s, it was retained as a co-national anthem along with "Nkosi Sikelel' iAfrika" from 1994 to 1997, when a new hybrid song incorporating elements of both songs was adopted as the country's new national anthem, which is still in use. History Background and inception In May 1918, C.J. Langenhoven wrote an Afrikaans poem called "Die Stem", for which music was composed in 1921 by , a reverend. The music composed that ended up being a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stemming
In linguistic morphology and information retrieval, stemming is the process of reducing inflected (or sometimes derived) words to their word stem, base or root form—generally a written word form. The stem need not be identical to the morphological root of the word; it is usually sufficient that related words map to the same stem, even if this stem is not in itself a valid root. Algorithms for stemming have been studied in computer science since the 1960s. Many search engines treat words with the same stem as synonyms as a kind of query expansion, a process called conflation. A computer program or subroutine that stems word may be called a ''stemming program'', ''stemming algorithm'', or ''stemmer''. Examples A stemmer for English operating on the stem ''cat'' should identify such strings as ''cats'', ''catlike'', and ''catty''. A stemming algorithm might also reduce the words ''fishing'', ''fished'', and ''fisher'' to the stem ''fish''. The stem need not be a word, for ...

The Stems
The Stems are a garage punk band formed in Perth, Western Australia in late 1983. They were founded by Dom Mariani in late 1983. The Stems are heavily influenced by 1960s garage rock and 1970s power pop. The band initially broke up in August 1987 and reformed in 2003, releasing a new album in 2007. Although the group disbanded in October 2009, as of 2013 The Stems are an ongoing live concern. History 1983: Formation The Stems formed in late 1983 when vocalist/guitarist Dom Mariani, formerly in The Go-Starts, was introduced to Richard Lane. Lane had seen Mariani in the final few gigs of The Go-Starts and had asked him for guitar lessons which developed into the decision was made to form The Stems. A friend, Gary Chambers, was recruited to join on drums, and bass guitarist John Shuttleworth was poached from the Pink Armadillos. In March 1984, the band had their debut gig at the Old Civic Theater in Perth, which was in support of The Saints and The Triffids. Their sound was influe ...

Stem Group
In phylogenetics, the crown group or crown assemblage is a collection of species composed of the living representatives of the collection, the most recent common ancestor of the collection, and all descendants of the most recent common ancestor. It is thus a way of defining a clade, a group consisting of a species and all its extant or extinct descendants. For example, Neornithes (birds) can be defined as a crown group, which includes the most recent common ancestor of all modern birds, and all of its extant or extinct descendants. The concept was developed by Willi Hennig, the formulator of phylogenetic systematics, as a way of classifying living organisms relative to their extinct relatives in his "Die Stammesgeschichte der Insekten", and the "crown" and "stem" group terminology was coined by R. P. S. Jefferies in 1979. Though formulated in the 1970s, the term was not commonly used until its reintroduction in 2000 by Graham Budd and Sören Jensen. Contents of the cro ...

Plant Stem
A stem is one of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, stores nutrients, and produces new living tissue. The stem can also be called halm or haulm. The stem is normally divided into nodes and internodes: * The nodes hold one or more leaves, as well as buds which can grow into branches (with leaves, conifer cones, or flowers). Adventitious roots may also be produced from the nodes. * The internodes distance one node from another. The term " shoots" is often confused with "stems"; "shoots" generally refers to new fresh plant growth including both stems and other structures like leaves or flowers. In most plants stems are located above the soil surface but some plants have underground stems. Stems have four main functions which are: * Support for and the elevation of leaves, flowers, and fruits. The st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stem (bicycle Part)
The stem is the component on a bicycle that connects the handlebars to the steerer tube of the bicycle fork. Sometimes called a ''goose neck'', a stem's design belongs to either a ''quill'' or ''threadless'' system, and each system is compatible with respective headset and fork designs: * Quill: the stem inserts into the steerer tube, which is threaded and does not extend above the headset. * Threadless: the stem clamps around the steerer tube, which is not threaded and extends above the headset. Quill versus threadless Although stems are commonly referred to as being of either the quill or threaded type, the thread in question is the one on the fork steerer tube. Quill stems require a steerer tube of the same length as the headset and head tube combined and thus must be matched to the specific bicycle model. Threadless systems use an unthreaded steerer tube, which extends into the stem and may be cut to length as desired in order to accommodate the height of the headset, ...

Stem Mixing And Mastering
Stem-mixing is a method of mixing audio material based on creating groups of audio tracks and processing them separately prior to combining them into a final master mix. Stems are also sometimes referred to as submixes, subgroups, or buses. The distinction between a stem and a separation is rather unclear. Some consider stem manipulation to be the same as separation mastering, although others consider stems to be sub-mixes to be used along with separation mastering. It depends on how many separate channels of input are available for mixing and/or at which stage they are on the way towards reducing them to a final stereo mix. The technique originated in the 1960s, with the introduction of mixing boards equipped with the capability to assign individual inputs to sub-group faders and to work with each sub-group (stem mix) independently from the others. The approach is widely used in recording studios to control, process and manipulate entire groups of instruments such as drums, ...

Stem (audio)
In audio production, a stem is a discrete or grouped collection of audio sources mixed together, usually by one person, to be dealt with downstream as one unit. A single stem may be delivered in mono, stereo, or in multiple tracks for surround sound. The beginnings of the process can be found in the production of early non-silent films. In "Das Land ohne Frauen" (Land Without Women), the first entirely German-made feature-length dramatic talkie released in 1929, about one-quarter of the movie contained dialogue, which was strictly segregated from the special effects and music. Mixing for films In sound mixing for film, the preparation of stems is a common stratagem to facilitate the final mix. Dialog, music and sound effects, called "D-M-E", are brought to the final mix as separate stems. Using stem mixing, the dialog can easily be replaced by a foreign-language version, the effects can easily be adapted to different mono, stereo and surround systems, and the music can be chang ...
