Problem: Race (human categorization):

The European Union uses the terms racial origin and ethnic origin synonymously in its documents and according to it "the use of the term 'racial origin' in this directive does not imply an acceptance of such [racial] theories".[full citation needed] Haney Lopez warns that using "race" as a category within the law tends to legitimize its existence in the popular imagination. In the diverse geographic context of Europe, ethnicity and ethnic origin are arguably more resonant and are less encumbered by the ideological baggage associated with "race". In European context, historical resonance of "race" underscores its problematic nature. In some states, it is strongly associated with laws promulgated by the Nazi and Fascist governments in Europe during the 1930s and 1940s. Indeed, in 1996, the European Parliament adopted a resolution stating that "the term should therefore be avoided in all official texts".

Who uses the terms racial origin and ethnic origin interchangeably?

A: The European Union

Problem: Antennas are characterized by a number of performance measures which a user would be concerned with in selecting or designing an antenna for a particular application. Chief among these relate to the directional characteristics (as depicted in the antenna's radiation pattern) and the resulting gain. Even in omnidirectional (or weakly directional) antennas, the gain can often be increased by concentrating more of its power in the horizontal directions, sacrificing power radiated toward the sky and ground. The antenna's power gain (or simply "gain") also takes into account the antenna's efficiency, and is often the primary figure of merit.
How could one deide what type of antenna is nedded for a project?

In October 1969, he proclaimed the current trade terms unfair, benefiting foreign corporations more than the Libyan state, and by threatening to reduce production, in December Jalloud successfully increased the price of Libyan oil.

How much money did Libya accrue in a year as a result of the Tripoli Agreement?
