Shade (shadow)

Shade is the blocking of sunlight (in particular direct sunshine) by any object, and also the shadow created by that object. Shade also consists of the colors grey, black, white, etc. It may refer to blocking of sunlight by a roof, a tree, an umbrella, a window shade or blind, curtains, or other objects.

Safety from the Sun for infants

In temperate and tropical zones (most places on Earth), shade is an important issue in providing cooling and shelter from harmful heat and ultraviolet emitted by the Sun.


Green plants produce shade by absorbing sunlight to invest as energy in photosynthesis to produce sugar. They also actively transpire, producing an additional cooling effect.

In gardening terms, there are various types of shade:

  • Full sun – more than five hours of direct sun per day.
  • Part shade – two to five hours of direct sun, or all-day dappled sun (sunlight shining through open trees).
  • Full shade – less than two hours of direct sun per day...

Under a dense forest canopy, light intensity can be very low. Special adaptations produce the shade tolerance that allows plants to survive in the understory. In addition, shade within a canopy can elicit shade avoidance responses whereby plants elongate their shoots in order to reach light for optimal photosynthesis.[1]

Gudang language

Gudang or Djagaraga (Pantyinamu/Yatay/Gudang/Kartalaiga and other clans) is an Australian Aboriginal language. It is the traditional language of the Gudang people, and is the northernmost language of the Cape York Peninsula. It is closely related to Urradhi (dialects Urradhi, Angkamuthi, Yadhaykenu, Wudhadhi, etc.), its neighbour to the south, and distantly related to its neighbour to the north, the Western-Central Torres Strait Language (Kala Lagaw Ya), from which it borrowed quite a few vocabulary items.

Leipzig–Jakarta list

The Leipzig–Jakarta list is a 100-word list of words used by linguists to test the degree of chronological separation of languages by comparing words that are resistant to borrowing. The Leipzig–Jakarta list became available in 2009.In the 1950s, the linguist Morris Swadesh published a list of 200 words called the Swadesh list, allegedly the 200 lexical concepts found in all languages that were least likely to be borrowed from other languages. Swadesh later whittled his list down to 100 items. The Swadesh list, however, was based mainly on intuition, according to Martin Haspelmath and Uri Tadmor.The Loanword Typology Project, with the World Loanword Database (WOLD), published by the Max Planck Digital Library, was established to rectify this problem. Experts on 41 languages from across the world were given a uniform vocabulary list and asked to provide the words for each item in the language on which they were an expert, as well as information on how strong the evidence that each word was borrowed was. The 100 concepts that were found in most languages and were most resistant to borrowing formed the Leipzig–Jakarta list. Only 62 items on the Leipzig–Jakarta list and on the 100-word Swadesh list overlap, hence a 38% difference between the two lists.

25% of the words in the Leipzig–Jakarta list are body parts: mouth, eye, leg/foot, navel, liver, knee, etc. Six animal words appear on the list: fish, bird, dog, louse, ant and fly – animals found everywhere humans can be found.The items house, name, rope and to tie are products of human culture, but are probably found in all present-day human societies. Haspelmath and Tadmor drew the conclusion that "rope is the most basic of human tools and tying is the most basic technology".

List of Greek and Latin roots in English/P–Z

The following is an alphabetical list of Greek and Latin roots, stems, and prefixes commonly used in the English language from P to Z. See also the lists from A to G and from H to O.

Some of those used in medicine and medical technology are not listed here but instead in the entry for List of medical roots, suffixes and prefixes.

List of Latin words with English derivatives

This is a list of Latin words with derivatives in English (and other modern languages).

Ancient orthography did not distinguish between i and j or between u and v. Many modern works distinguish u from v but not i from j. In this article, both distinctions are shown as they are helpful when tracing the origin of English words. See also Latin spelling and pronunciation.

Mystery in Space

Mystery in Space is the name of two science fiction American comic book series published by DC Comics, and of a standalone Vertigo anthology released in 2012. The first series ran for 110 issues from 1951 to 1966, with a further seven issues continuing the numbering during a 1980s revival of the title. An eight-issue limited series began in 2006.

Together with Strange Adventures, Mystery In Space was one of DC Comics' major science fiction anthology series. It won a number of awards, including the 1962 Alley Award for "Best Book-Length Story" and the 1963 Alley Award for "Comic Displaying Best Interior Color Work". The title featured short science fiction stories and a number of continuing series, most written by many of the best-known comics and science fiction writers of the day, including John Broome, Gardner Fox, Jack Schiff, Otto Binder, and Edmond Hamilton. The artwork featured a considerable number of the 1950s and 1960s finest comics artists such as Carmine Infantino, Murphy Anderson, Gil Kane, Alex Toth, Bernard Sachs, Frank Frazetta, and Virgil Finlay.

A shadow is a dark (real image) area where light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it. The cross section of a shadow is a two-dimensional silhouette, or a reverse projection of the object blocking the light.

A shed is typically a simple, single-story roofed structure in a back garden or on an allotment that is used for storage, hobbies, or as a workshop. Sheds vary considerably in their size and complexity of construction, from simple open-sided ones designed to cover bicycles or garden items to large wood-framed structures with shingled roofs, windows, and electrical outlets. Sheds used on farms or in industry can be large structures. The main types of shed construction are metal sheathing over a metal frame, plastic sheathing and frame, all-wood construction (the roof may be asphalt shingled or sheathed in tin), and vinyl-sided sheds built over a wooden frame. Small sheds may include a wooden or plastic floor, while more permanent ones may be built on a concrete pad or foundation. Sheds may be lockable to deter theft or entry by children, domestic animals, wildlife, etc.

A culture of shed enthusiasts exists in several countries for people who enjoy building sheds and spending time in them for relaxation. In Australia and New Zealand there are magazines called The Shed, an association for shed hobbyists (the Australian Men's Shed Association), and a book entitled Men and Sheds.

Space Ranger

Space Ranger is a science fiction hero who was published by DC Comics in several of their 1950s and 1960s anthology titles. He first appeared in Showcase #15 (July 1958) and was created by writers Edmond Hamilton and Gardner Fox and artist Bob Brown. The character has notable similarities to a preceding character named David "Lucky" Starr, created by novelist Isaac Asimov in his 1952 novel David Starr, Space Ranger. After appearing in Showcase #15 and 16, the Space Ranger was given a cover-starring series in Tales of the Unexpected, starting with issue #40 and lasting until #82 (1959–64). Afterwards, he moved to Mystery in Space for issues #92–99, 101, 103 (1964–65).
