Scorpion Releasing
Scorpions are predatory arachnids of the order Scorpiones. They have eight legs, and are easily recognized by a pair of grasping pincers and a narrow, segmented tail, often carried in a characteristic forward curve over the back and always ending with a stinger. The evolutionary history of scorpions goes back 435 million years. They mainly live in deserts but have adapted to a wide range of environmental conditions, and can be found on all continents except Antarctica. There are over 2,500 described species, with 22 extant (living) families recognized to date. Their taxonomy is being revised to account for 21st-century genomic studies. Scorpions primarily prey on insects and other invertebrates, but some species hunt vertebrates. They use their pincers to restrain and kill prey, or to prevent their own predation. The venomous sting is used for offense and defense. During courtship, the male and female grasp each other's pincers and dance while he tries to move her onto his ...

Scorpion Sting
A scorpion sting is an injury caused by the stinger of a scorpion resulting in the medical condition known as scorpionism, which may vary in severity. The anatomical part of the scorpion that delivers the sting is called a "telson". In typical cases, scorpion stings usually result in pain, paresthesia, and variable swelling. In serious cases, scorpion stings may involve the envenomation of humans by toxic scorpions, which may result in extreme pain, serious illness, or even death depending on the toxicity of the venom. Most scorpion stings range in severity from minor swelling to medically significant lesions, with only a few able to cause severe allergic, neurotic or necrotic reactions. However, scorpion stings account for approximately 3,000 deaths a year worldwide. The Brazilian yellow scorpion ('' Tityus serrulatus'') is one species known for being especially dangerous, being responsible for most scorpion sting fatalities in South America. Scorpion stings are seen all over the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle English
Middle English (abbreviated to ME) is a form of the English language that was spoken after the Norman conquest of 1066, until the late 15th century. The English language underwent distinct variations and developments following the Old English period. Scholarly opinion varies, but the '' Oxford English Dictionary'' specifies the period when Middle English was spoken as being from 1150 to 1500. This stage of the development of the English language roughly followed the High to the Late Middle Ages. Middle English saw significant changes to its vocabulary, grammar, pronunciation, and orthography. Writing conventions during the Middle English period varied widely. Examples of writing from this period that have survived show extensive regional variation. The more standardized Old English language became fragmented, localized, and was, for the most part, being improvised. By the end of the period (about 1470) and aided by the invention of the printing press by Johannes Gutenberg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orion (mythology)
In Greek mythology, Orion (; Ancient Greek: Ὠρίων or ; Latin: ''Orion'') was a giant huntsman whom Zeus (or perhaps Artemis) placed among the stars as the constellation of Orion. Ancient sources told several different stories about Orion; there are two major versions of his birth and several versions of his death. The most important recorded episodes are: his birth in Boeotia, his visit to Chios where he met Merope and raped her, being blinded by Merope's father, the recovery of his sight at Lemnos, his hunting with Artemis on Crete, his death by the bow of Artemis or the sting of the giant scorpion which became Scorpius, and his elevation to the heavens. Most ancient sources omit some of these episodes and several tell only one. These various incidents may originally have been independent, unrelated stories, and it is impossible to tell whether the omissions are simple brevity or represent a real disagreement. In Greek literature he first appears as a great hunter in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scorpio (astrology)
Scorpio () is the eighth astrological sign in the zodiac, originating from the constellation of Scorpius. It spans 210°–240° ecliptic longitude. Under the tropical zodiac (most commonly used in Western astrology), the Sun transits this sign on average from October 23 to November 21. Depending on which zodiac system one uses, someone born under the influence of Scorpio may be called a ''Scorpio'' or a ''Scorpionic''. Associations Scorpio is one of the water signs, the others being Cancer and Pisces. It is a fixed, negative sign. Scorpio is associated with three different animals: the scorpion, the snake, and the eagle. According to ''The Astrology Bible'', Scorpio's colors are deep red, maroon, black, and brown.

Scorpius (constellation)
Scorpius is a zodiac constellation located in the Southern celestial hemisphere, where it sits near the center of the Milky Way, between Libra to the west and Sagittarius to the east. Scorpius is an ancient constellation that pre-dates the Greeks; it is one of the 48 constellations identified by the Greek astronomer Ptolemy in the second century. Its old astronomical symbol is (♏︎). Notable features Stars Scorpius contains many bright stars, including Antares (α Sco), "rival of Mars," so named because of its distinct reddish hue; β1 Sco (Graffias or Acrab), a triple star; δ Sco ( Dschubba, "the forehead"); θ Sco ( Sargas, of unknown origin); ν Sco (Jabbah); ξ Sco; π Sco (Fang); σ Sco (Alniyat); and τ Sco (Paikauhale). Marking the tip of the scorpion's curved tail are λ Sco ( Shaula) and υ Sco (Lesath), whose names both mean "sting." Given their proximity to one another, λ Sco and υ Sco are sometimes referred to as the Cat's Eyes. The constellat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilim
A kilim ( az, Kilim کیلیم; tr, Kilim; tm, Kilim; fa, گلیم ''Gilīm'') is a flat tapestry- woven carpet or rug traditionally produced in countries of the former Persian Empire, including Iran, the Balkans and the Turkic countries. Kilims can be purely decorative or can function as prayer rugs. Modern kilims are popular floor coverings in Western households. Etymology The term 'kilim' originates from the Persian ''galīm'' (گلیم) where it means 'to spread roughly', perhaps of Akkadian or Aramean origin. another name for Galim(Gilim) is Plas, Ferdowsi and other persian poet mentioned both Galim and plas as synonyms in Shahnameh No 35 mentioned as Plas(pluNo14 mentioned as Gali History Like Pile weave, pile carpets, kilim have been produced since ancient times. The explorer Mark Aurel Stein found kilims dating to at least the fourth or fifth century CE in Hotan, China: :"As kilims are much less durable than rugs that have a pile to protect the warp and weft, i ...

Scorpion Motif
Many motifs are used in traditional kilims, handmade flat-woven rugs, each with many variations. In Turkish Anatolia in particular, village women wove themes significant for their lives into their rugs, whether before marriage or during married life. Some motifs represent desires, such as for happiness and children; others, for protection against threats such as wolves (''to the flocks'') and scorpions, or against the evil eye. These motifs were often combined when woven into patterns on kilims. With the fading of tribal and village cultures in the 20th century, the meanings of kilim patterns have also faded. In these tribal societies, women wove kilims at different stages of their lives, choosing themes appropriate to their own circumstances. Some of the motifs used are widespread across Anatolia and sometimes across other regions of West Asia, but patterns vary between tribes and villages, and rugs often expressed personal and social meaning.

Percent
In mathematics, a percentage (from la, per centum, "by a hundred") is a number or ratio expressed as a fraction (mathematics), fraction of 100. It is often Denotation, denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a Dimensionless quantity, dimensionless number (pure number); it has no unit of measurement. Examples For example, 45% (read as "forty-five per cent") is equal to the fraction , the ratio 45:55 (or 45:100 when comparing to the total rather than the other portion), or 0.45. Percentages are often used to express a proportionate part of a total. (Similarly, one can also express a number as a fraction of 1,000, using the term "per mille" or the symbol "".) Example 1 If 50% of the total number of students in the class are male, that means that 50 out of every 100 students are male. If there are 500 students, then 250 of them are male. Example 2 An increase of $0.15 on a price of $2.50 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ultraviolet
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact. F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluorescent
Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. It is a form of luminescence. In most cases, the emitted light has a longer wavelength, and therefore a lower photon energy, than the absorbed radiation. A perceptible example of fluorescence occurs when the absorbed radiation is in the ultraviolet region of the electromagnetic spectrum (invisible to the human eye), while the emitted light is in the visible region; this gives the fluorescent substance a distinct color that can only be seen when the substance has been exposed to UV light. Fluorescent materials cease to glow nearly immediately when the radiation source stops, unlike phosphorescent materials, which continue to emit light for some time after. Fluorescence has many practical applications, including mineralogy, gemology, medicine, chemical sensors (fluorescence spectroscopy), fluorescent labelling, dyes, biological detectors, cosmic-ray detection, ...
