X-return

The expected return on an investment, taking into account the level of risk involved.

X-factor

A mysterious or intangible quality or factor that contributes to success or attractiveness.

X-irradiation

The process of exposing something to high-energy radiation, such as X-rays, in order to sterilize it or modify its properties.

X-yield

The yield or return on an investment, calculated based on a specific variable or factor.

X-ray crystallography

A technique used to determine the arrangement of atoms within a crystal, using X-rays to create a diffraction pattern.

X-ray fluorescence

A analytical technique that uses X-rays to determine the elemental composition of a sample.

X-value

The value of something in terms of a specific variable or factor.

X-efficiency theory

A theory that explains the relationship between efficiency and the use of resources, and how this can be improved through changes in technology or management practices.

X-inefficiency

The lack of efficiency or productivity in a company or individual.

X-efficiency

The efficiency with which a company or individual produces goods or services, taking into account all available resources and technology.

X-risk

A risk or uncertainty that is difficult to predict or quantify.

The analysis of the value of something in terms of a specific variable or factor.

X-ray diffraction

A technique used to study the structure of materials, using X-rays to create a diffraction pattern.

X-ray imaging

A diagnostic technique that uses X-rays to create images of the inside of the body.

X-ray spectroscopy

A technique used to identify and measure the chemical elements in a sample, using X-rays to excite the atoms and measure their emitted radiation.
