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 ...
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
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 ...
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:
Improvements in agricultural productivity and technology are expected to be able to meet anticipated increased demand for resources, making a global human overpopulation scenario unlikely. [208] [209] [210] For any given production set, there is not a set amount of labor input (a "lump of labor") to produce that output.
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 ideal Otto cycle is an example of an isochoric process when it is assumed that the burning of the gasoline-air mixture in an internal combustion engine car is instantaneous. There is an increase in the temperature and the pressure of the gas inside the cylinder while the volume remains the same.
