The word diphthong is derived from the old Greek language. Here, "di" means "two" or "double", while the part "-phthong" means "sound" or "tone", from the basic word "phthalein", which means "speak", "creating sound by the voice".
A diphthong can be a lexeme of a language and as such it may be one syllable, but rarely.
The Price is Right
The Price is Right is a USA game show on CBS. The current version started in 1972, and was hosted by Bob Barker for a long time. However, in 2006, Bob Barker announced that he would leave the show. His last episode aired in June 2007. Comedian Drew Carey is now the host; his first episode aired in October 2007.
In this game, a person uses his shopping skills to correctly guess the price of different products, like in a market. Some products are simple household items, like toothpaste and vitamins. Other items are more expensive products, like furniture and cars. After the third and sixth games, the "Showcase Showdown" is played. The three players who got on stage in both halves of the show spin a wheel. They get two spins of the wheel. They have to be closest to $1.00 without going over. The person with the highest total moves on to the Showcase at the end of the show. If a player gets $1.00, they win $1,000 and get another spin. If they hit the $1.00 space on that spin, they win another $25,000. If they hit the 5¢ or 15¢ space, they win another $10,000. In the Showcase, the winners of the two Showcase Showdown games are shown prize packages. They make a bid on them, and whoever comes closest to the price of their showcase without going over wins it. If they are $250 or less from the price of their showcase, they win both showcases. If someone's bid was higher than the price of the real price, that person went over, and was disqualified from winning in that round.
From 1956 - 1963, the show aired on NBC and was hosted by Bill Cullen. From 1963 - 1965, the show aired on ABC and was also hosted by Bill Cullen.
Three nighttime syndicated versions of the show aired. The first one aired from 1972 to 1980. Until 1977, it was hosted by Dennis James. For the rest of its run, it was hosted by Bob Barker. From 1985 - 1986, another nighttime version of the show, named "The Nighttime Price Is Right", was made and was hosted by Tom Kennedy. A third nighttime version, "The New Price Is Right", was made from 1994 - 1995 and was hosted by Doug Davidson. Also special million dollar prime-time episodes where people could play different versions of games for $1,000,000 were made due to CBS shows being canceled.
Monophthong
A monophthong (pronounced "Mono-F-thong") is simply a vowel. The word monophthong comes from the old Greek language. "Mono" means "one" or "single", and the "-phthong" means "sound" or "tone", from the basic word "phthalein", which means "to speak", "create sound with the voice". The word monophthong shows that a vowel is spoken with exactly one tone and one mouth position. For example, when you say "teeth", then while you are creating the sound of the "ee", nothing changes for that sound.
A monophthong can be a lexeme of a language and as such it can as well be a syllable. There is no shorter syllable than a single monophthong.
Kalua
Kalua is a Hawaiian cooking method. The word "kalua" means "to cook in an underground oven" in Hawaiian. The oven is a hole in the ground called an imu. Kalua is most often used to cook pig. Kalua pig is a popular food at luaus.
Ancient Hawaiians used rocks from rivers to cook pig. They heated the rocks in the imu and the pig cooked with steam. They covered the pig with banana leaves, ti leaves, old mats and then dirt to keep the heat inside. This produced a unique taste that cannot be reproduced.
People today kalua pig in the same way that ancient Hawaiians did. Kalua pig is still served at luaus.
Ultraviolet
Ultraviolet is the part of the electromagnetic spectrum shown on the left side of the picture below as black—because humans cannot see light of such short wavelength (or high frequency). Many animals such as some insects, some reptiles, crocodiles, salamanders, and small birds can see things that this light. UV is a common abbreviation of ultraviolet, mainly used in technical contexts.
Ultraviolet is beyond the visible violet light in terms of frequency, wavelength, and energy. Its wavelengths are between about 10 nanometers (nm) to about 400 nanometers. Frequency and wavelength are closely related. The equation that shows this relationship is: ν = c/λ . Saying that something has a short wavelength is the same as saying that it has a high frequency.
Ultraviolet light is a type of ionizing radiation. It can damage or kill cells. Any electromagnetic radiation (light) that has a wavelength shorter than 450 nm may cause trouble. Therefore, humans that live in places with more ultraviolet light have adapted by getting darker skins. Pigments absorb the ultraviolet radiation, so it does not get through the skin to kill or injure cells inside. Injury to the skin by ultraviolet is called "sunburn."
The violet light and ultraviolet light differ in their wavelength, frequency, and quantum energy. The differences between ultraviolet light and x-rays are also wavelength, frequency and quantum energy. In the electromagnetic spectrum, ultraviolet is beyond violet, x-rays are beyond ultraviolet, and gamma rays are beyond x-rays.
Electromagnetic waves with a wavelength from about 400 nanometers down to about 10 nanometers are commonly called ultraviolet. Their characteristic photon energy is about 3 to 124 electronvolts.
Although the air of the Earth is transparent to a broad range of ultraviolet, some ultraviolet sunlight is absorbed at a very high altitude by the ozone layer. Recent and ongoing destruction of ozone in high altitudes caused by human influence—mostly by industrial chemicals and air travel—has greatly increased the amount of ultraviolet light reaching the Earth's surface. This, in turn, has increased the risk of skin cancer to mankind, and this risk will only increase with time unless the ozone layer is better protected.
Ultraviolet wavelengths less than 200 nanometers, X-rays, and gamma rays, are collectively called ionizing radiation since the energy in any such light quantum is high enough to 'kick' an electron out of an atom. This is why these kinds of radiation are dangerous to life. Ultraviolet light is subdivided into three main bands. UV-C has the shortest wavelengths and is dangerous ionizing radiation. Nitrogen and oxygen absorb the UV-C from solar radiation. UV-B has medium wavelength and is less dangerous to living things. The Earth's ozone layer absorbs most of it. UV-A from the Sun gets through the atmosphere entirely. It has wavelength almost as long as visible light, and many animals can see it but humans cannot.
Ordinary glass does not let radiation through if its wavelength is less than 200 nanometers, so it acts as a shield against the more dangerous range of ultraviolet light, but some special sorts of glass do not shield as well, including many car windows.
One use for ultraviolet radiation is tanning. Use of tanning devices can cause skin cancer because ultraviolet goes through the skin and causes destruction to cells, causing sunburn.
Because of the destructive power of ultraviolet light, it can be used to kill germs. Sunlight is a powerful disinfectant.
People need some ultraviolet light to convert cholesterol into vitamin D.
An ultraviolet lamp is one that emits mostly ultraviolet light. These germicidal lamps are often used to kill microbes (germs). They can be very powerful, so the people who work around them when they are turned on may need to wear protective glasses and keep their skin covered to avoid injury.
