41Surface Marker Buoy — (standard) = A Surface Marker Buoy, SMB or simply a blob is an inflatable buoy used by SCUBA divers, with a line, to mark the diver s position to their surface, safety boat while the diver is underwater.SMBs are inflated on the surface before… …
42Surface photovoltage — (SPV) measurements are a widely used method to determine the minority carrier diffusion length of semiconductors. Since the transport of minority carriers determines the behavior of the p n junctions that are ubiquitous in semiconductor devices,… …
43Surface piercing — Surface piercings are any body piercings that take place on the surface of the body through areas which are not particularly concave or convex, where the piercing canal transverses a surface flap of skin, rather than running completely through a… …
44Surface forces apparatus — The surface force apparatus (SFA) is a scientific instrument and technique pioneered by D. Tabor, R.H.S. Winterton, J.N. Israelachvili in the early 1970s at Cambridge University. By the mid 70 s Israelachvili had adapted the original design to… …
45Surface metrology — is the measuring of small scale features on surfaces, and is a branch of Metrology. Surface primary form, surface waviness and surface roughness are the parameters most commonly associated with the field. It is important to many disciplines and… …
46Surface states — are electronic states found at the surface of materials and are part of condensed matter physics. They are formed due to the sharp transition from solid material that ends with a surface and are found only at the atom layers closest to the… …
47Surface exposure dating — is a collection of geochronological techniques for estimating the length of time that a rock has been exposed at or near Earth s surface. Surface exposure dating is used to date glacial advances and retreats, erosion history, lava flows,… …
48Surface supplied diving — (also known as Hooka diving) refers to divers using equipment supplied with breathing gas using an umbilical cord from the surface, often from a diving support vessel but possibly, indirectly via a diving chamber.cite journal |author=Gernhardt,… …
49Surface brightness — is a concept used in astronomy when describing extended astronomical objects such as galaxies and nebulae.General descriptionThe apparent magnitude of an astronomical object is generally given as an integrated value mdash;if a galaxy is quoted as …
50Surface wave magnitude — The Surface wave magnitude (MS) is one of the magnitude scales used in seismology to measure the size of an earthquake. It is based on measurements in Rayleigh surface waves that primarily travel along the uppermost layers of the earth. It is… …
