The degree to which indigenous peoples ' rights and issues are accepted and recognised in practical instruments such as treaties and other binding and non-binding agreements varies, sometimes considerably.

How significant this is varies between lenses, and opinions differ on how much practical impact this has.

The use of computers ( IBM 650, 1620, and 7040 ) allowed analysis of a large sample size, and of more measurements and subgroups than had been previously practical with mechanical calculators, thus allowing an objective understanding of how human locomotion varies by age and body characteristics.

Part 15 of the FCC rules allows the use of spectrum without a license but emissions pursuant to this rule are not practical for broadcasting due to extremely restrictive power levels which limit range ( range varies depending on frequency spectrum ).

The automatic controller normally maintains the proper cabin pressure altitude by constantly adjusting the outflow valve position so that the cabin altitude is as low as practical without exceeding the maximum pressure differential limit on the fuselage, which varies between different aircraft types but is normally around 8. 6 psi.

Internal assessment varies by subject ( there may be oral presentations, practical work, or written works ) and in most cases is initially graded by the classroom teacher, whose grades are then verified or modified, as necessary, by an appointed, external moderator.

The clear cut definition of light and heavy crude varies because the classification is based more on practical grounds than theoretical.

But beginning, for all practical purposes, with Frederick Seebohm's English Village Community scholars have had to reckon with a theory involving institutional and agrarian continuity between Roman and Anglo-Saxon times which is completely at odds with the reigning concept of the Anglo-Saxon invasions.

One effect of the spirited give-and-take of these discussions was to focus attention on practical applications and the necessity of being armed with the facts: knowledge of the destructive force of even the tiniest `` tactical '' atomic weapon would have a bearing on judgments as to the advisability of its use -- to defend Berlin, for example ; ;

The practical definition may lead to confusion with the definition of a coulomb ( i. e., 1 amp-second ), but in practical terms this means that measures of a constant current ( e. g., the nominal flow of charge per second through a simple circuit ) will be defined in amperes ( e. g., " a 20 mA circuit ") and the flow of charge through a circuit over a period of time will be defined in coulombs ( e. g., " a variable-current circuit that flows a total of 10 coulombs over 5 seconds ").

Instead of starting from theory and applying theory to a particular case, casuists start with the particular case itself and then ask what morally significant features ( including both theory and practical considerations ) ought to be considered for that particular case.

His practical experience as a farm manager combined with socialist, " single-tax ," and Slavic communal ideas shaped his world view.

The 1976 definition of the astronomical unit was incomplete, in particular because it does not specify the frame of reference in which time is to be measured, but proved practical for the calculation of ephemerides: a fuller definition that is consistent with general relativity was proposed, and " vigorous debate " ensued until in August 2012 the International Astronomical Union adopted the current definition of 1 astronomical unit = 149597870700 meters.
