The process of using an adhesive to manufacture an assembly. In this article, the adhesive-bonded assembly will be called an adhesive joint, and the materials to which the adhesive adheres will be called the adherends. The adhesive bonding process consists of adhesive joint design, adherend surface preparation, adhesive application, adhesive joint assembly, solidification of the adhesive (if necessary), adhesive joint evaluation, and use of the assembly.
Industry:Science
The production of a magnetic field by a living object. The living object presently most studied is the human body, for two purposes: to find new techniques for medical diagnosis, and to gain information about normal physiology. Smaller organisms studied include birds, fishes, and objects as small as bacteria; many scientists believe that biomagnetics is involved in the ability of these creatures to navigate. This article deals only with the human body.

The only living animal phylum with true lobopods (annulate, saclike legs with internal musculature). There are about 70 known living species in two families, Peripatopsidae and Peripatidae. These terrestrial animals are frequently referred to as Peripatus. Onychophora comprise a single class or order of the same name. They were once considered a missing link between annelid worms and arthropods, but are best considered to be aligned with the arthropods.

The mass of an atom or molecule on a scale where the mass of a carbon-12 (<sup>12</sup>C) atom is exactly 12.0 atomic mass units. The mass of any atom is approximately equal to the total number of its protons and neutrons multiplied by the atomic mass unit, u = 1.6605387 × 10<sup>−24</sup> gram. (Electrons are much lighter, about 0.0005486 u.) No atom differs from this simple formula by more than 1%, and stable atoms heavier than helium all lie within 0.3%.

The relationships between properties of polymers, especially those affected by changes in temperature and the conversion of energy from one form to another. Like other materials, the bulk properties of polymers are determined by their chemical structure, but unlike many other classes of engineering materials, the range of properties that can be obtained is extremely wide. This is a consequence of the chemical and structural diversity of polymeric molecules.
Industry:Science
The rigid or mechanically strong outer layer of the Earth that can support stress. The lithosphere is divided into 12 major plates, the boundaries of which are zones of intense activity that produce many of the large-scale geological features that characterize the Earth. These plates move as coherent units with velocities of up to several centimeters per year, and their relative movement and interaction form the foundation for the theory of plate tectonics.
Industry:Science
The techniques concerned with constructing maps from geographic information. Maps are spatial representations of the environment. Typically, maps take graphic form, appearing on computer screens or printed on paper, but they may also take tactile or auditory forms for the visually impaired. Other representations such as digital files of locational coordinates or even mental images of the environment are also sometimes considered to be maps, or virtual maps.

The science that deals with the production, transmission, and perception of spoken language. At each level, phonetics overlaps with some other sciences, such as anatomy, physiology, acoustics, psychology, and linguistics. In each case, phonetics focuses on phenomena relevant to the study of spoken language. The outline presented below follows a speech signal from its production by the speaker through the medium of transmission to its perception by the hearer.
Industry:Science
The time rate of flow of light. It is radiant flux in the form of electromagnetic waves which affects the eye or, more strictly, the time rate of flow of radiant energy evaluated according to its capacity to produce visual sensation. The visible spectrum is ordinarily considered to extend from 380 to 760 nanometers in wavelength; luminous flux is radiant flux in that region of the electromagnetic spectrum. The unit of measure of luminous flux is the lumen.

The long, lustrous hair of the Angora goat, which originated in the area around Ankara (Angora), Turkey. This plateau, about 3000 ft (900 m) high, has a dry climate with extremes in temperature. The Angora goat probably originated before Biblical times, as references to the use of goat's hair are found in the Bible. Angora goats were brought into the United States from Turkey in 1849 and taken westward after the Civil War, especially to Texas and California.
