Noon

Noon (also midday or noon time) is usually defined as 12 o'clock in the daytime. The term midday is also used colloquially to refer to an arbitrary period of time in the middle of the day. Solar noon is when the sun crosses the meridian and is at its highest elevation in the sky, at 12 o'clock apparent solar time. The local or clock time of solar noon depends on the longitude and date. The opposite of noon is midnight.

In many cultures in the Northern Hemisphere, noon had ancient geographic associations with the direction "south" (as did midnight with "north" in some cultures). Remnants of the noon = south association are preserved in the words for noon in French (Midi) and Italian (Mezzogiorno), both of which also refer to the southern parts of the respective countries. Modern Polish, Ukrainian, and Serbian go a step farther, with the words for noon (południe, південь, пoднe – literally "half-day") also meaning "south" and the words for "midnight" (północ, північ, пoнoħ – literally "half-night", as with English mid(dle) meaning "half") also meaning "north".

List of The Keys to the Kingdom characters

The Keys to the Kingdom is a fantasy-adventure book series, written by Garth Nix, started in 2003 with Mister Monday and ended with "Lord Sunday". The series follows the story of Arthur Penhaligon and his charge as the Rightful Heir of the Architect to claim the Seven Keys to the Kingdom and the seven demesnes of the House.

Heroes

Arthur Penhaligon

Arthur, a 12-year-old boy, has recently moved to a town and wants to fit into it. After suffering an asthma attack, he is saved by a mysterious metal object, called a Key, given by an even stranger character, Mister Monday, whose servants bring an incurable plague to Arthur's town. Arthur hurries to the House, a mysterious structure that only he can see. Shortly after arriving in the House, Arthur discovers the structure of the house is a complete universe and is informed of his duty to unseat the seven Trustees who run the House, claim their Keys, and rule all of Creation. Arthur cannot live an ordinary life unless he overthrows all of the Trustees, who are also known as the Morrow Days. To do this, however, he must use the Keys, which infect him with sorcery and make him a Denizen of the House; and whenever Denizens appear in the Secondary Realms (everything in Creation that is not in the House, including Earth), they are "inimical to mortal life", i.e. incredibly harmful to reality. This dilemma is a constant theme in the books: as Arthur does not wish to turn into a Denizen; he often resists using the Keys, and only does when it is absolutely necessary.

Nun (letter)

Nun is the fourteenth letter of the Semitic abjads, including Phoenician Nūn , Hebrew Nun נ, Aramaic Nun , Syriac Nūn ܢܢ, and Arabic Nūn ن (in abjadi order). It is the third letter in Thaana (ނ), pronounced as "noonu".
Its sound value is [n].

The Phoenician letter gave rise to the Greek nu (Ν), Etruscan , Latin N, and Cyrillic Н.

Origins

Nun is believed to be derived from an Egyptian hieroglyph of a snake (the Hebrew word for snake, nachash begins with a Nun and snake in Aramaic is nun) or eel. Some have hypothesized a hieroglyph of fish in water as its origin (in Arabic, nūn means large fish or whale). The Phoenician letter was named nūn "fish", but the glyph has been suggested to descend from a hypothetical Proto-Canaanite naḥš "snake", based on the name in Ethiopic, ultimately from a hieroglyph representing a snake,

(see Middle Bronze Age alphabets). Naḥš in modern Arabic literally means "bad luck". The cognate letter in Ge'ez and descended Semitic languages of Ethiopia is nehas, which also means "brass".

Spleen

The spleen (from Greek σπλήν—splḗn) is an organ found in virtually all vertebrates. Similar in structure to a large lymph node, it acts primarily as a blood filter.

The spleen plays important roles in regard to red blood cells (also referred to as erythrocytes) and the immune system. It removes old red blood cells and holds a reserve of blood, which can be valuable in case of hemorrhagic shock, and also recycles iron. As a part of the mononuclear phagocyte system, it metabolizes hemoglobin removed from senescent erythrocytes. The globin portion of hemoglobin is degraded to its constitutive amino acids, and the heme portion is metabolized to bilirubin, which is removed in the liver.

The spleen synthesizes antibodies in its white pulp and removes antibody-coated bacteria and antibody-coated blood cells by way of blood and lymph node circulation. A study published in 2009 using mice found that the spleen contains, in its reserve, half of the body's monocytes within the red pulp. These monocytes, upon moving to injured tissue (such as the heart), turn into dendritic cells and macrophages while promoting tissue healing. The spleen is a center of activity of the mononuclear phagocyte system and can be considered analogous to a large lymph node, as its absence causes a predisposition to certain infections.

Spleen (Chinese medicine)

The Spleen (Chinese: 脾; pinyin: pí) is one of the zàng organs stipulated by Traditional Chinese Medicine (TCM). It is a functionally defined entity and not equivalent to the anatomical organ of the same name.

In the context of the zang-fu concept

As a zàng, the Spleen is considered to be a yin organ. Its associated yang organ is the Stomach. Both Spleen and Stomach are attributed to the Earth element.
