Raptio (in archaic or literary English rendered as rape) is a Latin term for, among several other meanings for senses of "taking", the large-scale abduction of women: kidnapping for marriage, concubinage or sexual slavery. The equivalent German term is Frauenraub (literally woman robbery).
Raptio was assumed to be a historical practice, hence the Latin term, but the 21st century has seen a resurgence of war rape, some of which has elements of bride kidnapping; for example, women and girls abducted by Boko Haram in Nigeria, the Lord's Resistance Army in Uganda and ISIS in the Middle East have been taken as wives by their abductors.
The tertiary sex ratio is equivalent to the adult sex ratio (ASR), which is defined as the ratio of adult males to females in a population. [ 6 ] [ 7 ] The operational sex ratio (OSR) is the ratio of sexually active males to females in a population, and is therefore derived from a subset of the individuals included when calculating the ASR.

Ratios of counts, given by (non-zero) natural numbers, are rational numbers, and may sometimes be natural numbers. A more specific definition adopted in physical sciences (especially in metrology) for ratio is the dimensionless quotient between two physical quantities measured with the same unit. [4]
A company's earnings before interest, taxes, depreciation, and amortization (commonly abbreviated EBITDA, [1] pronounced / ˈ iː b ɪ t d ɑː,-b ə-, ˈ ɛ-/ [2]) is a measure of a company's profitability of the operating business only, thus before any effects of indebtedness, state-mandated payments, and costs required to maintain its asset base.
The word "raptor" refers to several groups of avian and non-avian dinosaurs which primarily capture and subdue/kill prey with their talons.. Raptor (bird) or bird of prey, a bird that primarily hunts and feeds on vertebrates
The concepts of signal-to-noise ratio and dynamic range are closely related. Dynamic range measures the ratio between the strongest un-distorted signal on a channel and the minimum discernible signal, which for most purposes is the noise level. SNR measures the ratio between an arbitrary signal level (not necessarily the most powerful signal ...
In mathematics, two non-zero real numbers a and b are said to be commensurable if their ratio a / b is a rational number; otherwise a and b are called incommensurable. (Recall that a rational number is one that is equivalent to the ratio of two integers.) There is a more general notion of commensurability in group theory.
