Hair

Hair is a protein filament that grows from follicles found in the dermis, or skin. Hair is one of the defining characteristics of mammals. The human body, apart from areas of glabrous skin, is covered in follicles which produce thick terminal and fine vellus hair. Most common interest in hair is focused on hair growth, hair types and hair care, but hair is also an important biomaterial primarily composed of protein, notably keratin. Attitudes towards hair, such as hairstyles and hair removal, vary widely across different cultures and historical periods, but it is often used to indicate a person's personal beliefs or social position, such as their age, gender, or religion.

Overview

The word "hair" usually refers to two distinct structures:

Hairy RNA localisation element (HLE)

The hairy localisation element (HLE) is an RNA element found in the 3' UTR of the hairy gene. HLE contains two stem-loops. HLE is essential for the mediation of apical localisation and the two stem-loop structures act to allow the recognition of hairy mRNA by the localisation machinery. HLE is found in Drosophila species.

Amba (geology)

An amba (Ge'ez: አምባ āmbā, Tigrinya: እምባ^?imbā) is a characteristic geologic form in Ethiopia. It is a steep-sided, flat-topped mountain, often the site of villages, wells and their surrounding farmland. These settlements were located there because they were very defensible and often virtually inaccessible plateaus.

The original term in Amharic indicates a mountain fortress. Amba Geshen, for example, is a historically significant amba where members of royal families were kept under guard for their safety and to prevent their participation in plots against the sitting emperor. Other noted Ambas include Amba Aradam and Amba Alagi, sites of famous battles during the first and second Italo-Abyssinian Wars. In Tigrinya, the term is "Emba" (also spelled "Imba").

In 2008, a scientific mission identified on an amba near Harar, the Kondudo, one of just two feral horse populations in Africa.

Amba (condiment)

Amba (Arabic: عمبة‎, Hebrew: עמבה‎) is a tangy mango pickle condiment popular in Middle Eastern cuisine (particularly Iraqi and Israeli cuisines) but also popular in India. Its name derives from the Sanskrit for mango.

It is typically made of mangoes, vinegar, salt, mustard, turmeric, chili and fenugreek, similarly to savoury mango chutneys.

The name "amba" seems to have been derived from the Sanskrit word "amra", and the mango is a native of India.

Amba is frequently used in Iraqi cuisine, especially as a spicy sauce to be added to fish dishes, falafel, kubbah, kebabs, and eggs.

Amba is popular in Israel, where it was introduced by Iraqi Jews in the 1950s and 1960s. It is often served as a dressing on sabikh and as an optional topping on falafel, meorav yerushalmi, kebab, salads and shawarma sandwiches.

Similarly, Assyrians typically use amba along with falafel, too.

Amba is similar to the South Asian pickle achar. The principal differences are that amba has large pieces of mango rather than small cubes, and that achar also contains oil.

Amba (film)

Amba is a 1990 Indian Bollywood film produced and directed by Mohan Kumar. It stars Anil Kapoor and Meenakshi Seshadri.

Tree

In botany, a tree is a perennial plant with an elongated stem, or trunk, supporting branches and leaves in most species. In some usages, the definition of a tree may be narrower, including only woody plants with secondary growth, plants that are usable as lumber or plants above a specified height. Trees are not a taxonomic group but include a variety of plant species that have independently evolved a woody trunk and branches as a way to tower above other plants to compete for sunlight. In looser senses, the taller palms, the tree ferns, bananas and bamboos are also trees. Trees tend to be long-lived, some reaching several thousand years old. The tallest known tree, a coast redwood named Hyperion, stands 115.6 m (379 ft) high. Trees have been in existence for 370 million years. It is estimated that there are just over 3 trillion mature trees in the world.

A tree typically has many secondary branches supported clear of the ground by the trunk. This trunk typically contains woody tissue for strength, and vascular tissue to carry materials from one part of the tree to another. For most trees it is surrounded by a layer of bark which serves as a protective barrier. Below the ground, the roots branch and spread out widely; they serve to anchor the tree and extract moisture and nutrients from the soil. Above ground, the branches divide into smaller branches and shoots. The shoots typically bear leaves, which capture light energy and convert it into sugars by photosynthesis, providing the food for the tree's growth and development. Flowers and fruit may also be present, but some trees, such as conifers, instead have pollen cones and seed cones; others, such as tree ferns, produce spores instead.

Trees (band)

Trees was an American new wave one-man band, fronted by Dane Conover, from San Diego, California. Trees only released one album on MCA Records, which was produced by Earle Mankey called Sleep Convention (1982). It was a critical success but a commercial failure. The band also filmed five low budget music videos.

Because of its album's commercial failure, Conover ended Trees to move on to other projects such as 'PopGems' with his wife Marisa, and both are still active in writing and recording pop music, and collaborating with other musicians. America Records had temporary rights from MCA to re-release five songs from the album from 1982 to 1984.

As of June 2007, Conover and his wife Marisa created a profile on YouTube and uploaded three of the Trees music videos. Two of the three had never been aired before, which were "Delta Sleep", and "India". "Shock of the New" however aired on MTV2 once. In November 2007, he uploaded the "Red Car" music video, and on September 18, 2008, he uploaded the "Come Back" music video.
