Fusion energy gain factorA fusion energy gain factor, usually expressed with the symbol Q, is the ratio of fusion power produced in a nuclear fusion reactor to the power required to maintain the plasma in steady state. The condition of Q = 1, when the power being released by the fusion reactions is equal to the required heating power, is referred to as breakeven, or in some sources, scientific breakeven. The energy given off by the fusion reactions may be captured within the fuel, leading to self-heating.
Cultural studiesCultural studies, also called the cultural sciences, is an interdisciplinary field or scientific branch that examines the dynamics of contemporary culture (including its politics and popular culture) and its historical foundations. Cultural studies researchers generally investigate how cultural practices relate to wider systems of power associated with, or operating through, social phenomena. These include ideology, class structures, national formations, ethnicity, sexual orientation, gender, and generation.
