51Otoplasty — Otoplasty: the pre operative front aspect (left), and the post operative front aspect (right) of an infantile otopexy (ear pinback) correction to a girl. Otoplasty (Greek ōtoûs, ear + plassein, to shape) denotes the surgical and non surgical… …
52Industrial radiography — is the use of ionizing radiation to view objects in a way that cannot be seen otherwise. It is not to be confused with the use of ionizing radiation to change or modify objects; radiography s purpose is strictly viewing. Industrial radiography… …
53plate tectonics — plate tectonic, adj. Geol. a theory of global tectonics in which the lithosphere is divided into a number of crustal plates, each of which moves on the plastic asthenosphere more or less independently to collide with, slide under, or move past… …
54building construction — Techniques and industry involved in the assembly and erection of structures. Early humans built primarily for shelter, using simple methods. Building materials came from the land, and fabrication was dictated by the limits of the materials and… …
55Fullerene — Buckminsterfullerene C60 (left) and carbon nanotubes (right) are two examples of structures in the fullerene family …
56Field emission — (FE) is the emission of electrons from the surface of a condensed phase into another phase due to the presence of high electric fields. In this phenomenon, electrons with energies below the Fermi level tunnel through the potential barrier at the… …
57Opto-isolator — This article is about the electronic component. For the optical component, see optical isolator. Schematic diagram of an opto isolator showing source of light (LED) on the left, dielectric barrier in the center, and sensor (phototransistor) on… …
58Lipid raft — organisation, region (1) is standard lipid bilayer, while region (2) is a lipid raft. The plasma membrane of cells is made of a combination of glycosphingolipids and protein receptors organized in glycolipoprotein microdomains termed lipid… …
59Chemical-mechanical planarization — Chemical Mechanical Polishing/Planarization is a process of smoothing surfaces with the combination of chemical and mechanical forces. It can be thought of as a hybrid of chemical etching and free abrasive polishing. Contents 1 Description 2… …
60Crystallographic restriction theorem — The crystallographic restriction theorem in its basic form was based on the observation that the rotational symmetries of a crystal are usually limited to 2 fold, 3 fold, 4 fold, and 6 fold. However, quasicrystals can occur with other symmetries …
