Neem oil

Neem oil is a vegetable oil pressed from the fruits and seeds of the neem (Azadirachta indica), an evergreen tree which is endemic to the Indian subcontinent and has been introduced to many other areas in the tropics. It is the most important of the commercially available products of neem for organic farming and medicines.

Neem oil varies in color; it can be golden yellow, yellowish brown, reddish brown, dark brown, greenish brown, or bright red. It has a rather strong odor that is said to combine the odours of peanut and garlic. It is composed mainly of triglycerides and contains many triterpenoid compounds, which are responsible for the bitter taste. It is hydrophobic in nature; in order to emulsify it in water for application purposes, it must be formulated with appropriate surfactants.

Azadirachtin is the most well known and studied triterpenoid in neem oil. The azadirachtin content of neem oil varies from 300ppm to over 2500ppm depending on the extraction technology and quality of the neem seeds crushed. Nimbin is another triterpenoid which has been credited with some of neem oil's properties as an antiseptic, antifungal, antipyretic and antihistamine. Neem oil also contains several sterols, including (campesterol, beta-sitosterol, stigmasterol).

Oil!

Oil! is a novel by Upton Sinclair published in 1927 told as a third person narrative, with only the opening pages written in the second person. The book was written in the context of the Harding administration's Teapot Dome Scandal and takes place in Southern California. It is a social and political satire skewering the human foibles of all its characters.

The main character is James Arnold Ross Jr., nicknamed Bunny, son of an oil tycoon. Bunny's sympathetic feelings toward oilfield workers and socialists provoke arguments with his father throughout the story.

The novel served as a loose inspiration for the 2007 film There Will Be Blood.

Characters

Oil

An oil is any neutral, nonpolar chemical substance that is a viscous liquid at ambient temperatures and is both hydrophobic (immiscible with water, literally "water fearing") and lipophilic (miscible with other oils, literally "fat loving"). Oils have a high carbon and hydrogen content and are usually flammable and slippery.

The general definition of oil includes classes of chemical compounds that may be otherwise unrelated in structure, properties, and uses. Oils may be animal, vegetable, or petrochemical in origin, and may be volatile or non-volatile. They are used for food, fuel, lubrication, and the manufacture of paints, plastics, and other materials. Specially prepared oils are used in some religious ceremonies as purifying agents.

Etymology

First attested in English 1176, the word oil comes from Old French oile, from Latin oleum, which in turn comes from the Greek ἔλαιον (elaion), "olive oil, oil" and that from ἐλαία (elaia), "olive tree", "olive fruit". The earliest attested forms of the word are the Mycenaean Greek 𐀁𐀨𐀺, e-ra-wo and 𐀁𐁉𐀺, e-rai-wo, written in the Linear B syllabic script.

Oil (band)

Oil is a Christian thrash metal band from Long Beach, California, USA. The band was formed in 1997 by Ron Rinehart, the former vocalist with Dark Angel, who converted to Christianity at a Harvest Crusade after Dark Angel's dissolution in 1992. Other members include lead guitarist Blake Nelson (formerly with Deceiver, Desire and Captain Black) and drummer Jason Vander Pal. Oil has released two studio albums and one live album.

In 2004, Rinehart left the band to pursue other non-musical interests. The rest of the group is looking for a new vocalist.

Biography

Oil's first release was a self-financed EP in 1999.

The Refine album was well-reviewed for its honest, no frills metal approach. The band performed live gigs, including a show at the Stryper Expo, but Rinehart received an injury soon after the album release which meant Oil did not perform for nearly a year. Once recovered, Rinehart and Oil returned to performing, being announced as special guests to Disciple in April.

The band recorded a live album Choice Cuts Off the Chopping Block at the First Baptist Church in Downey, California, in November 2002. The record included two new acoustic songs, "This Is My Prayer" and "Medicine Man". When bass guitarist Matthew Joy opted out in May 2003, Oil recruited Jonathan Thiemens of Blind Sacrificies as a temporary replacement. This became permanent in July.

Azadirachta indica

Azadirachta indica, also known as Neem,Nimtree, and Indian Lilac is a tree in the mahogany family Meliaceae. It is one of two species in the genus Azadirachta, and is native to India and the Indian subcontinent including Nepal, Pakistan, Bangladesh and Sri Lanka. It is typically grown in tropical and semi-tropical regions. Neem trees now also grow in islands located in the southern part of Iran. Its fruits and seeds are the source of neem oil.

Description

Neem is a fast-growing tree that can reach a height of 15–20 metres (49–66 ft), rarely to 35–40 metres (115–131 ft). It is evergreen, but in severe drought it may shed most or nearly all of its leaves. The branches are wide and spreading. The fairly dense crown is roundish and may reach a diameter of 15–20 metres (49–66 ft) in old, free-standing specimens. The neem tree is very similar in appearance to its relative, the Chinaberry (Melia azedarach).

The opposite, pinnate leaves are 20–40 centimetres (7.9–15.7 in) long, with 20 to 31 medium to dark green leaflets about 3–8 centimetres (1.2–3.1 in) long. The terminal leaflet is often missing. The petioles are short.
