Population mobility

It is sometimes useful to consider the abundances in the groundwater and sorbed together as the mobile population, in contrast to those fixed within the host rock. 

Conceptualizations, once arrived at, interact to produce new conceptualizations, new technology, from which, once more, new concepts and new needs may emerge. Television, for instance, derives as a concept from motion pictures and radio and, even though it was introduced only a comparatively short time ago, has rapidly become a central part of homes at all levels of society in our culture. Watching television has tended to produce a more uniform culture through greater exposure to common stimuli, has reduced the amount of time available for free interaction by members of any particular household, and has resulted in the creation of such implements as "TV trays" and "TV dinners" to accommodate the need for more time around the television set. Automobiles have made possible the movement to the suburbs, the virtual end of public transportation in many parts of our country, and a resultant increased dependency on private means of transportation. In its turn, this has produced a more mobile population, a proliferation of roads, a tendency to think of distance in terms of units of time, the destruction of the countryside, and an increased need to deal with air pollution. 

A mobile population of hydrogen has also been observed by anelastic spectroscopy measurements that were carried out by Palombo et al. Heating NaAlIij doped with 2 mol% TiCl3 to 436 K introduces a thermally activated relaxation process with a frequency of 1 kHz at 70 K. This denotes the formation of a point defect with a very high mobility ( 5 x lO jumps/s at 70 K). The relaxation involves the reorientation of H around Ti. 

Originally, it was though that some of the sorbed gas molecules are present as a mobile population dissolved in the bulk of the polymer according to Henry s law, and are free to diffuse down a concentration gradient, whilst the remaining gas molecules are bound at a fixed number of adsorption sites or holes occurring within the polymer. It was assumed that the bound and mobile molecules are in equilibrium. The total concentration Cgq of sorbed molecules at sufficiently low concentrations (where Henry s law is obeyed) is then obtained from equations (10) and (11)...

In this case, the quantitative dominance of material attributes considered Transcaucasian (and therefore as belonging to a mobile population) is subsumed under a set of deeply ingrained, but little interrogated, associations that equate levels of material substantiality with levels of sociopolitical complexity. 

It is possible that temple estates located outside the main cities of the north were independent of secular control, but whether or not this is the case, there is an additional import to such a situation. Cultic centers located in the countryside are vital hinges in complex networks of integration that draw together administration and populace, city and countryside, mobile populations and their sedentary kin in ways that transcend the centrifugal forces of fragmentation and dispersal.
