### placement | distance:

Genetic distance
* function of recombination fraction.
* is estimated from differences in allele frequencies found in allozyme surveys
  - expressed as a value between pair of populations
  - scaled in centiMorgans
* tends to cluster around two values, near zero and near one.

Horizontal axis
* is distance
  - magnetic declination and thus represents sample orientation
  - the toroidal angle
* is time, vertical axis is processes
  - used to display different states at different heights
* represents time, vertical axis represent the value of x.

Measurement of distance
* Measurements of distance are also related to measures of similarity and dissimilarity.
* is one of the most fundamental studies in astronomy.

Mileage
* are distance
  - measurements
  - ratios
* is determined primarily by driving habits
  - measured from the closer of duty station or point of departure to destination and return
  - specified of tracks, cables, canals, pipelines, or routes travelled
* is the distance of the most direct route from the old residence to the new residence
  - most important thing a used car buyer looks at, next to price
  - sum of the total miles driven divided by the amount of fuel used

### placement | distance | nearness:

Proximity
* Proximities are nearness
  - vicinities
* Refers to the relationship established by clustered items.
* has an effect on people.
* is defined based on shortest paths between objects
  - essentially distance measured either through a roads network or as the crow flies
  - relative to the time it takes energy to cross a given space
* means that things near each other are associated with each other.
* refers to the distance between search terms.
+ Combat stress reaction, History: Conflicts :: Mental illnesses
  * These centers avoided the use of terms like war neurosis and shell shock. The PIE principles stand for proximity, immediacy, and expectancy. Proximity means treat the casualties close to the front line. Immediacy means treat them without delay and do not wait until the physically wounded are treated. Expectancy means ensure every casualty expects to return to combat. These numbers do not include numbers of causalities that were ineffective when returned to combat. Edgar Jones and Simon Wessely. Apr 1, 2005.

Remove
* are distance.
* is distance
* lead, cadmium, alluminum, mercury and other toxic metals which interfere in enzyme function.
* toxins from the body.
* toxins, cleanses and softens skin, soothes tired muscles.

### placement | distance | remove:

Paint remover
* Many paint removers contain solvents.
* are among the most toxic products in the home.
* can damage linoleum, asphalt, plastic, and vinyl.

Sight distance
* are long and mostly limited by topography.
+ Trail, Trail types and use, Equestrian trails: Roads
  * Horseback riding has continued to be a popular activity for many trail users. Again, 'horse trails' must be built to different standards than other trails. Sight distance is an important issue with horse trails, as is overhead and side clearance. While trail surface types are a relatively unimportant issue with hikers, they may be an important issue with horses.

### placement | distance:

Wavelength
* All wavelengths are in vacuum
  - have essentially the same mechanism of tissue interaction
* Most wavelengths used in astronomy are in the MHz and GHz range.
* Some wavelengths absorb more strongly than others.
* are characteristic of the chemical composition as well as the temp of the gas
  - distances, usually measured in meters
  - orientations
  - part of spectrums
* extend from the far infrared to the extreme ultraviolet.
* fall within certain bands, depending on temperature.
* have length, intensity and purity dimensions.
* is distance
* reach the end of the medium at different times, causing the light pulse to spread.
* tend to be scattered in all directions.
