The common name for any of 14 species of rodents in the family Cricetidae. The natural range of most of these species is Asia but a few, such as the common hamster (<i>Cricetus cricetus</i>), are found in Europe.
Industry:Science
The asynchronous transmission of messages by using computers and data-communication networks. Historically, electronic mail (or e-mail) referred to any of a number of technologies that allowed people to send documents to one another through electronic means. It was frequently used to describe both wirephoto (the precursor of the facsimile (fax) machine) and telegraphy. Subsequently, usage of the term focused upon the narrower sense given above.
Industry:Science
The general method and specific techniques for storing energy derived from some primary source in a form convenient for use at a later time when a specific energy demand is to be met, often in a different location.
Industry:Science
Superplasticity refers to the ability of a material to develop unusually high tensile elongations at temperatures between 0.4 and 0.6 of its melting point in kelvins. Strains in excess of 1000% are frequently obtainable. By contrast, elongations often considerably less than 100% strain are typical for materials in a nonsuperplastic state when deformed at the same strain rates and temperatures where superplasticity is obtained in these materials.
Industry:Science
The intentions, desires, goals, and needs that determine human and animal behavior. An inquiry is made into a person's motives in order to explain that person's actions. The answer may have important consequences.

Submarines have been around for about 400 years. Their stealth plays an important role in a modern naval force. However, the lack of a significant civilian or industrial requirement for this mode of transportation has restricted the scope of its development and left the technology largely shrouded in the military. Compared with airplane aerodynamics, for example, submarine hydrodynamics receives little attention in the open scientific literature.
Industry:Science
The branch of physics that deals with the influence of an electric field on the optical properties of matter, especially in crystalline form. These properties include transmission, emission, and absorption of light.
Industry:Science
That branch of physics which endeavors to explain the macroscopic properties of a system on the basis of the properties of the microscopic constituents of the system. Usually the number of constituents is very large. All the characteristics of the constituents and their interactions are presumed known; it is the task of statistical mechanics (often called statistical physics) to deduce from this information the behavior of the system as a whole.
Industry:Science
The description of the future state of the climate, that is, the average or expected atmospheric and Earth-surface conditions, for example, temperature, precipitation, humidity, winds, and their range of variability.
Industry:Science
The applications to medicine and biology of sound waves that have a frequency higher than the audible spectrum. Biomedical applications of ultrasound range from cell sonicators using frequencies in the kilohertz range to ultrasonic imaging in the megahertz range. The best-known application, ultrasonic imaging, is the second most utilized diagnostic imaging modality, after x-rays. High-intensity ultrasound has been used for therapeutic applications.
