A diagram or drawing that shows features transected by a given plane; specifically, a vertical section drawn at right angles to the longer axis of a geologic feature
A diagram or drawing that shows features transected by a given plane, usually a vertical plane so that the view shows features through the depth of the earth
A diagram or drawing that shows the sequence of rocks and sediment layers as they occur in a vertical plane; commonly drawn from the ground surface down to some selected depth, such as the bedrock surface
(physics) the probability that a particular interaction (as capture or ionization) will take place between particles; measured in barns a sample meant to be representative of a whole population a section created by a plane cutting a solid perpendicular to its longest axis
In nuclear physics, a measure of the probability that a given atomic nucleus will exhibit a specific reaction (absorption, scattering, or nuclear fission) in relation to a particular incident particle. Cross section is expressed in terms of area, and its value is chosen so that, if the bombarding particle hits a circular target of this size perpendicular to its path and centred at the nucleus, the given reaction occurs. If it misses the area, the reaction does not occur. The unit of cross section is the barn, which equals 10^-24 sq cm. Cross-section values for a given nucleus depend on the energy of the bombarding particle and the kind of reaction and are often different from the actual cross-sectional area of the nucleus
(1) A contraction of capture cross section (2) A diagram showing geological features transected by a vertical plane (3) A designation for a specific area (e g , borehole cross section)
A graph or plot of ground elevation across a stream valley or a portion of it, usually along a line perpendicular to the stream or direction of flow Cultural Resource Values: Floodplain values associated with the harvest of natural products (agricultural, aquacultural and forestry uses), as well as historical/archaeological, scientific and recreation/open space values Cumulative Impacts: The impacts on the environment that result from the incremental impact of an action when added to other past, present and reasonably foreseeable actions Cumulative impacts can result from individually minor but collectively significant actions taking place over a period of time
The side view of an object sliced along its vertical plane (For example, when you slice a two-layer cake, you can see the cross section of the cake--the bottom layer of cake, a layer of frosting, the top layer of cake, and the top layer of frosting )
A measure of the probability of a particular nuclear reaction occuring between a projectile and a target The probability is expressed as an area that the target presents The unit is the barn 1 barn = 10-28 m2
Cross section (sigma) is the device SEE response to ionizing radiation For an experimental test for a specific LET, sigma = #errors/(ion fluence) The units for cross section are cm2 per device or per bit
