Means of production

Means of production , also called means of labour are the materials, tools and other instruments used by workers to make products. This includes: machines, tools materials, plant and equipment, land, raw materials, money, power generation, and so on: anything necessary for labor to produce. The term originates with Marx, who explicitly differentiates means of production from capital. For Marx, means of production were the instruments and materials of labor independent of the mode of producing and appropriating surplus. On the other hand means of production become capital, only within a particular set of social relations: when those means of production participate in the process of exploiting labor for surplus value.
Means of production is sometimes confused with factors of production. The term factors of production is typically understood as an explanation for income as duly paid to owners of each means of production and also to the workers themselves within capitalism. By comparison, the term means of production applies to these means independent of their ownership and their compensation, and regardless of whether the mode of producing is capitalist, feudal, slave, communal or otherwise.

Spear

A spear is an ancient weapon used for hunting and war, consisting of a shaft, usually of wood, with a sharpened head. The head may be simply the sharpened end of the shaft itself, as is the case with bamboo spears, or it may be of another material fastened to the shaft. The most common design is of a metal spearhead, shaped somewhat like a dagger.
Spears were arguably one of the most common personal weapons from the late Bronze Age until the advent of firearms. They may be seen as the ancestor of such weapons as the lance, the halberd, the naginata and the pike. One of the earliest weapons fashioned by human beings and their ancestors, it is still used for hunting and fishing, and its influences can still be seen in contemporary military arsenals as the rifle mounted bayonet.
Spears can be used as both melee and ballistic weapons. Spears used primarily for thrusting tend to have heavier and sturdier designs than those intended exclusively for throwing. Two of the most noted throwing spears are the javelin thrown by the ancient Greeks and the pilum used by the Romans.

The Mouflon

The Mouflon is a species of wild sheep and as such is one of the Caprinae or "goat antelopes". It is thought to be one of the two ancestors for all modern domestic sheep breeds. It is red-brown with a dark back-stripe, light colored saddle patch and underparts. The males are horned and the females are horned or polled.
They originated in Southwest Asia, where the species known as Asiatic mouflon lives. They were introduced to the islands of Corsica, Sardinia, and Cyprus during the neolithic period, perhaps as feral domesticated animals, where they naturalized to the mountainous interiors of these islands over the past few thousand years, giving rise to the species known as European mouflon . They are now rare on the islands, but have been successfully introduced into central Europe, including Germany, Austria, the Czech Republic, Slovakia, Hungary, and Romania, even in some northern European countries, such as Finland.
The scientific classification of the Mouflon is disputed but the European Mouflon may be considered as either Ovis musimon or Ovis ammon musimon.

Fever is a frequent medical symptom that describes an increase in internal body temperature to levels that are above normal (37°C, 98.6°F). Fever is most accurately characterized as a temporary elevation in the body’s thermoregulatory set-point, which is usually by about 1-2°C. Fever differs from hyperthermia, which is an increase in body temperature over the body’s thermoregulatory set-point .
The elevation in thermoregulatory set-point means that the previous "normal body temperature" is considered hypothermic, and effector mechanisms kick in. The person who is developing the fever has a cold sensation, and an increase in heart rate, muscle tone and shivering attempt to counteract the perceived hypothermia, thereby reaching the new thermoregulatory set-point.
