Buttocks

The buttocks (singular: buttock) are two rounded portions of the anatomy, located on the posterior of the pelvic region of apes (including humans), and many other bipeds or quadrupeds, and comprise a layer of fat superimposed on the gluteus maximus and gluteus medius muscles. Physiologically, the buttocks enable weight to be taken off the feet while sitting. In many cultures, they play a role in sexual attraction. Many cultures have also used them as a target for corporal punishment. There are several connotations of buttocks in art, fashion, culture and humor, and the English language is replete with many popular synonyms. In humans the buttocks are located between the lower back and the perineum.

Anatomy

The buttocks are formed by the masses of the gluteal muscles or "glutes" (the gluteus maximus muscle and the gluteus medius muscle) superimposed by a layer of fat. The superior aspect of the buttock ends at the iliac crest, and the lower aspect is outlined by the horizontal gluteal crease. The gluteus maximus has two insertion points: ¹⁄₃ superior portion of the linea aspera of the femur, and the superior portion of the iliotibial tractus. The masses of the gluteus maximus muscle are separated by an intermediate intergluteal cleft or "crack" in which the anus is situated.

Donkey

The donkey or ass (Equus africanus asinus), is a domesticated member of the horse family, Equidae. The wild ancestor of the donkey is the African wild ass, E. africanus. The donkey has been used as a working animal for at least 5000 years. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. Working donkeys are often associated with those living at or below subsistence levels. Small numbers of donkeys are kept for breeding or as pets in developed countries.

A male donkey or ass is called a jack, a female a jenny or jennet; a young donkey is a foal. Jack donkeys are often used to mate with female horses to produce mules — the biological "reciprocal" of a mule, from a stallion and jenny as its parents instead, is called a hinny.

Asses were first domesticated around 3000 BC, probably in Egypt or Mesopotamia, and have spread around the world. They continue to fill important roles in many places today. While domesticated species are increasing in numbers, the African wild ass and another relative, the onager, are endangered. As beasts of burden and companions, asses and donkeys have worked together with humans for millennia.

Nitric acid

Nitric acid (HNO₃), also known as aqua fortis and spirit of niter, is a highly corrosive mineral acid.

The pure compound is colorless, but older samples tend to acquire a yellow cast due to decomposition into oxides of nitrogen and water. Most commercially available nitric acid has a concentration of 68% in water. When the solution contains more than 86% HNO₃, it is referred to as fuming nitric acid. Depending on the amount of nitrogen dioxide present, fuming nitric acid is further characterized as white fuming nitric acid or red fuming nitric acid, at concentrations above 95%.

Nitric acid is the primary reagent used for nitration – the addition of a nitro group, typically to an organic molecule. While some resulting nitro compounds are shock- and thermally-sensitive explosives, a few are stable enough to be used in munitions and demolition, while others are still more stable and used as pigments in inks and dyes. Nitric acid is also commonly used as a strong oxidizing agent.

Mandate

Mandate may refer to:

League of Nations mandates

Mandate (criminal law)

A criminal court may impose a "mandate" as part of a legal process on a person accused of a crime consisting of an obligation to engage in certain conditions or activities in exchange for suspension or reduction in penalty; such as, conditions of probation, conditional discharges, or other conditional sentences. For example, a defendant convicted of driving while intoxicated or drug possession may be mandated to engage in alcoholism or substance abuse rehabilitation. The term is paradoxical because acceptance of the "mandate" is a voluntary act by the defendant, who also has the option of serving what would most generally (though the relative weight is a matter determined by the individual's perspective and readiness to change) be viewed as a harsher alternative, such as incarceration. In this sense, the mandate is not truly mandatory, but is instead a type of legal fiction wherein the court assumes an illusion of power which, in actuality, is constrained by the defendant's free will.

Mandate (international law)

In international law, a mandate is a binding obligation issued from an inter-governmental organization (e.g. the United Nations) to a country which is bound to follow the instructions of the organization.

Before the creation of the United Nations, all mandates were issued from the League of Nations. An example of such a mandate would be Australian New Guinea, which is officially the Territory of Papua.
