Kaw Lake

Kaw Lake is a reservoir completed in 1976 in the northern reaches of the U.S. state of Oklahoma, near Kaw City. It is approximately 8 miles (13 km) east of Ponca City.

Kaw Dam is 9,466 feet (2,885 m) long and 121 feet (37 m) above the stream bed. The dam lies 654 miles (1,053 km) above the mouth of the Arkansas River. The top of the flood control pool is 1,044.5 feet (318.4 m), while the normal operating level is 1,010 feet.

The Reservoir covers approximately 17,040 acres (69 km²). It is the seventh largest lake in Oklahoma by surface area. At normal levels, the lake holds 428,600 acre feet (528,700,000 m³) of water, the ninth largest lake in capacity in Oklahoma. (See List of lakes in Oklahoma) It lies mostly in Kay County and partially in Osage County.

Kaw Dam was authorized by Congress in the Flood Control Act of 1962. Ground was broken for the dam on May 21, 1966. The original town of Kaw City was covered by the waters of Kaw Lake in 1975. The city was rebuilt about two miles west of the old site during the late 1960s. The dam was completed by the Corps of Engineers in May 1976. The cost of the dam and the lake was $111 million.

The Chronicles of Prydain

The Chronicles of Prydain is a pentalogy of children's high fantasy Bildungsroman novels by Lloyd Alexander. Henry Holt published one annually from 1964 to 1968; the second earned a 1966 Newbery Honor and the last won the 1969 Newbery Medal.

The five novels follow one protagonist Taran from youth to maturity, most overtly in the fourth book, Taran Wanderer. Taran has the title Assistant Pig-Keeper at Caer Dallben but initially dreams of being a grand hero. His most important companions in adventure are Princess Eilonwy, a girl his age; Fflewddur Fflam, a wandering bard and minor king; Gurgi, a wild hominid between animal and man; and Doli, a dwarf.

Inspiration and development

Thematically the novels draw upon Welsh mythology, particularly the Mabinogion. The novels are not, however, retellings of those myths, a point Alexander himself makes in an author's note for The Book of Three: stories have been conflated, and characters have been changed in both role and motive, so a student of Welsh culture should be prepared as Arawn becomes the books' dark arch enemy and Gwydion's negative traits are replaced with unclouded heroism.

List of craters on Mars: H-N

This is a list of craters on Mars. There are hundreds of thousands of impact crater on Mars, but only some of them have names. This list here only contains named Martian craters starting with the letter H – N (see also lists for A – G and O – Z).

Large Martian craters (greater than 60 km in diameter) are named after famous scientists and science fiction authors; smaller ones (less than 60 km in diameter) get their names from towns on Earth. Craters cannot be named for living people, and small crater names are not intended to be commemorative - that is, a small crater isn't actually named after a specific town on Earth, but rather its name comes at random from a pool of terrestrial place names, with some exceptions made for craters near landing sites. Latitude and longitude are given as planetographic coordinates with west longitude.

Lake

A lake is an area of variable size filled with water, localized in a basin, that is surrounded by land, apart from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean (except for sea lochs in Scotland and Ireland), and therefore are distinct from lagoons, and are also larger and deeper than ponds, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which are usually flowing. However most lakes are fed and drained by rivers and streams.

Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers. In some parts of the world there are many lakes because of chaotic drainage patterns left over from the last Ice Age. All lakes are temporary over geologic time scales, as they will slowly fill in with sediments or spill out of the basin containing them.

Many lakes are artificial and are constructed for industrial or agricultural use, for hydro-electric power generation or domestic water supply, or for aesthetic or recreational purposes.

Pigment

A pigment is a material that changes the color of reflected or transmitted light as the result of wavelength-selective absorption. This physical process differs from fluorescence, phosphorescence, and other forms of luminescence, in which a material emits light.

Many materials selectively absorb certain wavelengths of light. Materials that humans have chosen and developed for use as pigments usually have special properties that make them ideal for coloring other materials. A pigment must have a high tinting strength relative to the materials it colors. It must be stable in solid form at ambient temperatures.

For industrial applications, as well as in the arts, permanence and stability are desirable properties. Pigments that are not permanent are called fugitive. Fugitive pigments fade over time, or with exposure to light, while some eventually blacken.

Pigments are used for coloring paint, ink, plastic, fabric, cosmetics, food, and other materials. Most pigments used in manufacturing and the visual arts are dry colorants, usually ground into a fine powder. This powder is added to a binder (or vehicle), a relatively neutral or colorless material that suspends the pigment and gives the paint its adhesion.
