Structural Functionalism | Overview Structural functionalism, or simply functionalism, is “a framework for building theory that sees society as a complex system whose parts work together to promote solidarity and stability”. This approach looks at society through a macro-level orientation, which is a broad focus on the social structures that shape society as a whole, and believes that society has evolved […]
Expressed Powers | Definition & Example Expressed Powers: Superman, as any American knows, can fly. He also has X-ray vision and is really very strong. How do we know these things? They are expressed both verbally (when Superman tells people what he can do) and non-verbally (when he just does them). Powers that aren’t made […]
Linear Approximation | Formula & Example In mathematics, a linear approximation is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite differences to produce first-order methods for solving or approximating solutions to equations. Given a twice continuously differentiable function {\displaystyle f} of one real variable, Taylor’s theorem for the case {\displaystyle n=1} states that {\displaystyle f(x)=f(a)+f'(a)(x-a)+R_{2}\ } […]
Behavioral Isolation | Definition & Example The different mating rituals of animal species create extremely powerful reproductive barriers, termed sexual or Behavioral isolation, that isolates apparently similar species in the majority of the groups of the animal kingdom. In dioecious species, males and females have to search for a partner, be in proximity to each other, carry […]
Ballista The ballista (Latin, from Greek βαλλίστρα ballistra[1] and that from βάλλω ballō, “throw”), plural ballistae, sometimes called bolt thrower, was an ancient missile weapon that launched a large projectile at a distant target. Developed from earlier Greek weapons, it relied upon different mechanics, using two levers with torsion springs instead of a tension prod […]
Alkyl Group | What Is An Alkyl Group In organic chemistry, an alkyl group substituent is an alkane missing one hydrogen. The term alkyl is intentionally unspecific to include many possible substitutions. An acyclic alkyl has the general formula CnH2n+1. A cycloalkyl is derived from a cycloalkane by removal of a hydrogen atom from a ring and has the general formula CnH2n-1. Typically an alkyl is a part […]
Electronegativity Trend | What Is Electronegativity Trend? Electronegativity Trend, symbol χ, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (electron density) towards itself. An atom’s electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged […]
Linear Approximation Formula | Defination In mathematics, a linear approximation formula is an approximation of a general function using a linear function (more precisely, an affine function). They are widely used in the method of finite differences to produce first order methods for solving or approximating solutions to equations. This approximation is crucial to many […]
Hydroxyl Group | What Is A Hydroxyl Group A hydroxyl group increases the ECL value of a fatty acid greatly, especially on polar columns, and if the hydroxyl group is derivatized, the nature of the derivative has a profound effect on the elution profile for different isomers. The hydroxyl group is a functional group consisting […]
