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 stems ke ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Scanning Transmission Electron Microscopy
A scanning transmission electron microscope (STEM) is a type of transmission electron microscope (TEM). Pronunciation is tÉ›mor ›sti:i:É›m As with a conventional transmission electron microscope (CTEM), images are formed by electrons passing through a sufficiently thin specimen. However, unlike CTEM, in STEM the electron beam is focused to a fine spot (with the typical spot size 0.05 – 0.2 nm) which is then scanned over the sample in a raster illumination system constructed so that the sample is illuminated at each point with the beam parallel to the optical axis. The rastering of the beam across the sample makes STEM suitable for analytical techniques such as Z-contrast annular dark-field imaging, and spectroscopic mapping by energy dispersive X-ray (EDX) spectroscopy, or electron energy loss spectroscopy (EELS). These signals can be obtained simultaneously, allowing direct correlation of images and spectroscopic data. A typical STEM is a conventional transmission el ...

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 crown gr ...

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. However ...

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 acc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wisconsin Death Trip (album)
''Wisconsin Death Trip'' is the debut studio album by American industrial metal band Static-X, released on March 23, 1999, by Warner Bros. Records. The band was formed after lead singer Wayne Static and drummer Ken Jay met at a Virgin Records store in Chicago. After being introduced by the Smashing Pumpkins lead singer Billy Corgan, the two decided to head out west to California to enlist a lead guitarist and bassist. Once in California, Koichi Fukuda became guitarist, and not long after, they discovered Californian Tony Campos to complete the lineup as their bassist. Warner Bros. Records discovered the band in California and signed them in February 1998. ''Wisconsin Death Trip'' peaked at number 107 on the US ''Billboard'' 200 and number one on the Top Heatseekers chart, and was certified platinum by the RIAA in 2001.
