Often, too, the social institutions are housed in these pavilions and palaces and bridges, for these great structures are not simply `` historical monuments '' ; ;

Often it is recognized that all the details of the pattern may not be essential to the outcome but, because the pattern was empirically determined and not developed through theoretical understanding, one is never quite certain which behavior elements are effective, and the whole pattern becomes ritualized.

Often the burrows are only an inch or two apart, and the bee cities cover several acres.

Often, therefore, there are a number of rules having the same effect, and commonly other sets of rules as well, having the opposite effect.

Often the coefficients are chosen so that the elements occupy a contiguous area of memory.

Often these procedures are coupled with legislation or other common law doctrines that establish standards for proper rulemaking.

Often, low-floor trams are fitted with nonpivoting bogies and many tramway enthusiasts see this as a retrograde step, as it leads to more wear of both track and wheels and also significantly reduces the speed at which a tram can round a curve.

Often they are at key strategic points.
