The blades are the most important part of a turbine: their design is crucial in capturing as much energy from the steam as possible and converting it into rotational energy by spinning the rotor round. All turbines have a set of rotating blades attached to the rotor and spin it around as steam hits them.
Gender variance is defined as the persistent sense that a person's gender identity is incongruent with the person's biological sex. The definition further excludes the element of persistence for persons under the age of 21 and including, without limitation, transitioned transsexuals.
The gender binary, also referred to as gender binarism (sometimes shortened to just binarism), is the classification of sex and gender into two distinct, opposite and disconnected forms of masculine and feminine. It is one general type of a gender system. As one of the core principles of genderism, it can describe a social boundary that discourages people from crossing or mixing gender roles, or from identifying with three or more forms of gender expression altogether.
