Symbol

A symbol is a person or a concept that represents, stands for or suggests another idea, visual image, belief, action or material entity. Symbols take the form of words, sounds, gestures, ideas or visual images and are used to convey other ideas and beliefs. For example, a red octagon may be a symbol for "STOP". On a map, a blue line might represent a river. Numerals are symbols for numbers. Alphabetic letters may be symbols for sounds. Personal names are symbols representing individuals. A red rose may symbolize love and compassion. The variable x in a mathematical equation may symbolize the position of a particle in space.

In cartography, an organized collection of symbols forms a legend for a map.

Etymology

The word derives from the Greek symbolon (σύμβολον) meaning token or watchword. It is an amalgam of syn- "together" + bole "a throwing, a casting, the stroke of a missile, bolt, beam." The sense evolution in Greek is from "throwing things together" to "contrasting" to "comparing" to "token used in comparisons to determine if something is genuine." Hence, "outward sign" of something. The meaning "something which stands for something else" was first recorded in 1590, in Edmund Spenser's Faerie Queene.

Voice of Music

Voice Of Music (abbreviated V-M) was the premier brand of V-M Corporation, an American audio equipment manufacturing company (EIA manufacturer's code 857).

History

Founded in June 1944 by Walter Miller in Benton Harbor, Michigan. The company originally manufactured only 78 rpm record changers and labeled them simply as "A V-M Product". The brand name "Voice of Music" was suggested by a V-M engineer and first used in 1952.

V-M kept up with each innovation in records and this required significant investment to retool their record changers. First came two speed changers after Columbia Records introduced the LP in 1948, then adding 45rpm after RCA brought that innovation to market in 1949, and ultimately ending up with the fourth speed (16⅔ rpm) for "talking books" in 1954. The changers themselves were innovative - the three and four speed models especially featuring reliable, jam-proof mechanisms.

Amplified phonographs were introduced in the early 1950s, and V-M brought out the Model 700 tape recorder late in 1954. Throughout the '50's and '60's, tape recorders, phonographs, consoles and components by V-M were popular with consumers for a variety of reasons. V-M Corporation's "Educational Systems" tape recorders and phonos with rugged cases were popular with schools and institutions. A brief entry into the audiophile market in 1970 with the V-M "Professional Series" was technically successful - but by this point, V-M Corporation was too financially weak to back a successful marketing campaign, so these products are rare and sought after today.

DV

DV is a format for storing digital video. It was launched in 1995 with joint efforts of leading producers of video camera recorders.

The original DV specification, known as Blue Book, was standardized within the IEC 61834 family of standards. These standards define common features such as physical videocassettes, recording modulation method, magnetization, and basic system data in part 1. Part 2 describes the specifics of 525-60 and 625-50 systems. The IEC standards are copyrighted publications available for purchase from IEC or ANSI.

In 2005, DV was superseded by the successor format HDV, which used the same tape format with a different video codec. Some cameras at the time had the ability to switch between DV and HDV recording modes.

DV compression

DV uses lossy compression of video while audio is stored uncompressed. An intraframe video compression scheme is used to compress video on a frame-by-frame basis with the discrete cosine transform (DCT).

Closely following ITU-R Rec. 601 standard, DV video employs interlaced scanning with the luminance sampling frequency of 13.5 MHz. This results in 480 scanlines per complete frame for the 60 Hz system, and 576 scanlines per complete frame for the 50 Hz system. In both systems the active area contains 720 pixels per scanline, with 704 pixels used for content and 16 pixels on the sides left for digital blanking. The same frame size is used for 4:3 and 16:9 frame aspect ratios, resulting in different pixel aspect ratios for fullscreen and widescreen video.

Veterinary physician

A veterinary physician, colloquially called a vet, shortened from veterinarian (American English, Australian English) or veterinary surgeon (British English), is a professional who practices veterinary medicine by treating disease, disorder, and injury in non-human animals.

Description

In many countries, the local nomenclature for a veterinarian is a regulated and protected term, meaning that members of the public without the prerequisite qualifications and/or licensure are not able to use the title. In many cases, the activities that may be undertaken by a veterinarian (such as treatment of illness or surgery in animals) are restricted only to those professionals who are registered as a veterinarian. For instance, in the United Kingdom, as in other jurisdictions, animal treatment may only be performed by registered veterinary physicians (with a few designated exceptions, such as paraveterinary workers), and it is illegal for any person who is not registered to call themselves a veterinarian or prescribe any treatment.
