Isochore maps in geology are also referred to as True Vertical Thickness (TVT) maps. [2] [3] Thus, an isochore and isopach map are the same only when both the top and bottom surfaces of the layer shown are horizontal. When the layer shown is inclined, as is usually the case, the thicknesses displayed in an isochore map of the layer will be ...
Isochore may refer to: Isochore (genetics) Isochore map, in geology; Isochore, in physics a line representing the variation of pressure with temperature when the volume of the substance operated on is constant. iso-choric process, in thermodynamics
An isochrone map in geography and urban planning is a map that depicts the area accessible from a point within a certain time threshold. [1] An isochrone (iso = equal, chrone = time) is defined as "a line drawn on a map connecting points at which something occurs or arrives at the same time". [ 2 ]
In genetics, an isochore is a large region of genomic DNA (greater than 300 kilobases) with a high degree of uniformity in GC content; that is, guanine (G) and cytosine (C) bases. The distribution of bases within a genome is non-random: different regions of the genome have different amounts of G-C base pairs, such that regions can be classified ...
Heat flows into the loop through the top isotherm and the left isochore, and some of this heat flows back out through the bottom isotherm and the right isochore, but most of the heat flow is through the pair of isotherms. This makes sense since all the work done by the cycle is done by the pair of isothermal processes, which are described by Q ...
The isochore model was proposed by Bernardi and colleagues to explain the observed non-uniformity of genomic fragments in the genome. [2] However, recent sequencing of complete genomic data refuted the isochoric model. Its main predictions were:
Design and Implementation: This step involves making decisions about all of the aspects of map design, as listed below, and implementing them using computer software. In the manual drafting era, this was a very linear process of careful decision making, in which some aspects needed to be implemented before others (often, projection first).
In the case of homotopy, the continuous deformation from one map to the other is of the essence, and it is also less restrictive, since none of the maps involved need to be one-to-one or onto. Homotopy does lead to a relation on spaces: homotopy equivalence. There is a name for the kind of deformation involved in visualizing a homeomorphism.
