Trefoil Knot Arb
A trefoil () is a graphic form composed of the outline of three overlapping rings, used in architecture, Pagan and Christian symbolism, among other areas. The term is also applied to other symbols with a threefold shape. A similar shape with four rings is called a quatrefoil. Architecture Ornamentation 'Trefoil' is a term in Gothic architecture given to the ornamental foliation or cusping introduced in the heads of window-lights, tracery, and panellings, in which the centre takes the form of a three-lobed leaf (formed from three partially overlapping circles). One of the earliest examples is in the plate tracery at Winchester Cathedral (1222–1235). The fourfold version of an architectural trefoil is a quatrefoil. A simple trefoil shape in itself can be symbolic of the Trinity, while a trefoil combined with an equilateral triangle was also a moderately common symbol of the Christian Trinity during the late Middle Ages in some parts of Europe, similar to a barbed quatrefoil. ...

Clover
Clovers, also called trefoils, are plants of the genus ''Trifolium'' (), consisting of about 300 species of flowering plants in the legume family Fabaceae originating in Europe. The genus has a cosmopolitan distribution with the highest diversity in the temperate Northern Hemisphere, but many species also occur in South America and Africa, including at high altitudes on mountains in the tropics. They are small annual, biennial, or short-lived perennial herbaceous plants, typically growing up to tall. The leaves are trifoliate (rarely, they have more or fewer than three leaflets; the more (or fewer) leaflets the leaf has, the rarer it is; see four-leaf clover), with stipules adnate to the leaf-stalk, and heads or dense spikes of small red, purple, white, or yellow flowers; the small, few-seeded pods are enclosed in the calyx. Other closely related genera often called clovers include '' Melilotus'' (sweet clover) and '' Medicago'' (alfalfa or Calvary clover). As legume ...

Fleur-de-lis
The ''fleur-de-lis'', also spelled ''fleur-de-lys'' (plural ''fleurs-de-lis'' or ''fleurs-de-lys''), is a common heraldic charge in the (stylized) shape of a lily (in French, and mean and respectively). Most notably, the ''fleur-de-lis'' is depicted on the flag of Quebec and on the traditional coat of arms of France that was used from the High Middle Ages until the French Revolution in 1792, and then again in brief periods in the 19th century. This design still represents France and the House of Bourbon in the form of Heraldry#Marshalling, marshalling in the arms of Coat of arms of Spain, Spain, Coat of arms of Quebec, Quebec, and Coat of arms of Canada, Canada — for example. Other European nations have also employed the symbol. The ''fleur-de-lis'' became "at one and the same time, religious, political, dynastic, artistic, emblematic, and symbolic", especially in French heraldry. The Mary, mother of Jesus, Virgin Mary and Saint Joseph are among saints often depicted wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Girl Guiding And Girl Scouting
A Girl Guide or Girl Scout is a member of a section of some Guiding organisations who is between the ages of 10 and 14. Age limits are different in each organisation. Girl Scouts and Girl Scout organizations already existed in Britain and other Commonwealth countries when Robert Baden-Powell founded The Girl Guides Association in 1910. There are many Girl Scouts organizations, e.g. the British Girl Scouts and Girl Scouts of the USA. The two terms are used synonymously within this article. Girl Guides are organised into units/troops averaging 15–30 girls under guidance of a team of leaders. Units subdivide into patrols of about six Guides and engage in outdoor and special interest activities. Units may affiliate with national and international organisations. Some units, especially in Europe, have been co-educational since the 1970s, allowing boys and girls to work together as Scouts. There are other programme sections for older and younger girls.

VHF Omnidirectional Range
Very High Frequency Omnidirectional Range Station (VOR) is a type of short-range VHF radio navigation system for aircraft, enabling aircraft with a VOR receiver to determine the azimuth (also radial), referenced to magnetic north, between the aircraft to/from fixed VOR ground transmitter, radio beacons. VOR and the first DME(1950) system (referenced to 1950 since different from today's DME/N) to provide the slant range distance, were developed in the United States as part of a U.S. civil/military program for Aeronautical Navigation Aids in 1945. Deployment of VOR and DME(1950) began in 1949 by the U.S. CAA (Civil Aeronautics Administration). ICAO standardized VOR and DME(1950) in 1950 in ICAO Annex ed.1. Frequencies for the use of VOR are standardized in the very high frequency (VHF) band between 108.00 and 117.95 MHz Chapter 3, Table A. To improve azimuth accuracy of VOR even under difficult siting conditions, Doppler VOR (DVOR) was developed in the 1960s. VOR is accordi ...

Fallout Shelter
A fallout shelter is an enclosed space specially designated to protect occupants from radioactive debris or fallout resulting from a nuclear explosion. Many such shelters were constructed as civil defense measures during the Cold War. During a nuclear explosion, matter vaporized in the resulting fireball is exposed to neutrons from the explosion, absorbs them, and becomes radioactive. When this material condenses in the rain, it forms dust and light sandy materials that resemble ground pumice. The fallout emits alpha and beta particles, as well as gamma rays. Much of this highly radioactive material falls to Earth, subjecting anything within the line of sight to radiation, becoming a significant hazard. A fallout shelter is designed to allow its occupants to minimize exposure to harmful fallout until radioactivity has decayed to a safer level, over a few weeks or months. Principle A fallout shelter is designed to protect its occupants from: * the mechanical and thermal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hazard Symbol
Hazard symbols are universally recognized Symbol, symbols designed to alert individuals to the presence of Hazard, hazardous or dangerous materials, locations, or conditions. These include risks associated with Electromagnetic field, electromagnetic fields, Electrical injury, electric currents, toxic chemicals, Explosive, explosive substances, and Radioactivity, radioactive materials. Their design and use are often governed by laws and standards organizations to ensure clarity and consistency. Hazard symbols may vary in color, background, borders, or accompanying text to indicate specific dangers and levels of risk, such as toxicity classes. These symbols provide a quick, universally understandable visual warning that transcends language barriers, making them more effective than text-based warnings in many situations. List of standardized hazard symbol systems Examples of common symbols Tape with yellow and black diagonal stripes is commonly used as a generic hazard warni ...

Recycling Symbol
The universal recycling symbol ( or in Unicode) is a symbol consisting of three chasing arrows folded in a Möbius strip. It is an internationally recognized symbol for recycling. The symbol originated on the first Earth Day in 1970, created by Gary Anderson (designer), Gary Anderson, then a 23-year-old student, for the Container Corporation of America. The symbol is not trademarked and is in the public domain. Many variations on the logo have been created since its creation. The unicode U+2672 glyph is: ♲ History Worldwide attention to environmental issues led to the first Earth Day in 1970. Container Corporation of America, a large producer of recycled paperboard, sponsored a contest for art and design students at high schools and colleges across the country to raise awareness of environmental issues. The contest, which drew more than 500 submissions, was won by Gary Anderson (designer), Gary Anderson, whose entry was the image now known as the universal recycling symbol. ...

Balkenkreuz
The ''Balkenkreuz'' () is a straight-armed cross that was first introduced in 1916–1918 and later became the emblem of the ''Wehrmacht'' (German Armed Forces) and its branches from 1935 until the end of World War II. It was used by the '' Wehrmacht Heer'' (Army), ''Luftwaffe'' (Air Force), and ''Kriegsmarine'' (Navy). History Balkenkreuz symbol is based on the cross of the Teutonic Order. Germany's ''Luftstreitkräfte'' (the army air service of the German Imperial Army) first officially adopted the ''Balkenkreuz'' in mid-April 1918 (about a week before the death of Manfred von Richthofen), and used it from that time until World War I ended in November 1918. The IdFlieg directive of 20 March 1918 to all manufacturers states in the first sentence (translated to English): "To improve the recognition of our aircraft, the following is ordered: ... In paragraph 2, the second sentence specifies: "This alteration is to be carried out by 15 April 1918." The closing sentence reads: " ...
