Often this network of underground drainage feeds back to surface drainage along the edges of larger rivers, which are the effective base level.

Often underground power stations form part of pumped storage hydroelectricity schemes, whose basic function is to level load: they use cheap or surplus off-peak power to pump water from a lower lake to an upper lake, then, during peak periods ( when electricity prices are often high ), the power station generates power from the water held in the upper lake.

Often the living person has graciously given consent for the Ibbur.

Often the revenants are associated with the spreading of disease among the living.

Often additional bedrooms are ' stacked ' on top of the second living area, hence the name ' stacked split level '.

Often clinical settings use a list of the activities of daily living as an assessment document, without any reference to the other elements of the model ; Roper heself rejected the use of the list of ADLs as a " checklist " as she stated that it was essential not simply to read the title of the ADL, but to base assessment on knowledge of the scope of the ADL as assessed using the 5 key factors.

Often the figures sit or sprawl across the tombstones in an attitude of grief, nostalgia, pensiveness, or anguish, like fellow mourners at the grave, or ghosts sociably mingling with the living, instead of being perched neatly on pedestals.

* Often variable efficacy due to the influences of various biotic and abiotic factors ( since biopesticides are usually living organisms, which bring about pest / pathogen control by multiplying within the target insect pest / pathogen )

Often a given body of water will have several entirely different names given to it by different peoples living along its shores.

) Often these relatives are living in more urban areas.

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

Often, the criteria had moral bases, such as in the case of Pierre de La Primaudaye's L ' Académie française and Guillaume Telin's Bref sommaire des sept vertus & c .. Encyclopaedists encountered several problems with this approach, including how to decide what to omit as unnecessary, how to structure knowledge that resisted structure ( often simply as a consequence of the sheer amount of material that deserved inclusion ), and how to cope with the influx of newly discovered knowledge and the effects that it had on prior structures.

As most programming languages are Turing-complete, it is possible to introduce user-defined lazy control structures in eager languages as functions, though they may depart from the language's syntax for eager evaluation: Often the involved code bodies ( like ( i ) and ( j )) need to be wrapped in a function value, so that they are executed only when called.

Often folding involves first the establishment of regular secondary and supersecondary structures, in particular alpha helices and beta sheets, and afterward tertiary structure.

Often, but not always, the player must build specific structures to unlock more advanced units in the tech tree.

Often the flat rooftops of these structures were used for sleeping in warm weather.

Often referred to as a quasiparticle, it represents an excited state in the quantum mechanical quantization of the modes of vibrations of elastic structures of interacting particles.

Often Hispanic settlements in Northern New Mexico are just places on the map for hundreds of years without formalized boundaries and governmental structures ; no mayor or village council.

Often some parts of the object state can be shared, and it is common practice to hold them in external data structures and pass them to the flyweight objects temporarily when they are used.

Often, supplemental curb pedestal mounts, intended to support a signal for a different approach road, are used when primary signals are partially obscured due to structures such as overpasses, approaches around a building that obscures the primary signal mountings, and unusual approach geometry.

* Often require that structure be electrically isolated from other structures and ground.

Often this is achieved by using non-conductive plastic or wooden structures for supporting the equipment under test.

Often, feature structures are written like this:

Often it is very difficult to determine the exact buckling load in complex structures using the Euler formula, due to the difficulty in deciding the constant K. Therefore, maximum buckling load often is approximated using energy conservation.

Often multiple circuits are the same voltage, but mixed voltages can be found on some structures.

Often Winnipeg stands in for United States cities, which sadly have modernized their downtowns with steel and glass structures making them all but impossible to use as suitable outdoor locations for stories set in the first half of the 20th century.

Often, the study of bionics emphasizes implementing a function found in nature rather than just imitating biological structures.

Often a distinction is made between ' local ' structures of discourse ( such as relations among sentences, propositions, and turns ) and ' global ' structures, such as overall topics and the schematic organization of discourses and conversations.

Often, students listened repeatedly to recordings of conversations ( for example, in the language lab ) and focused on accurately mimicking the pronunciation and grammatical structures in these dialogs.

Often, in order to be retained as commercially viable structures within an urban environment, or as part of an urban regeneration project, they may be repurposed for alternative activities.

Often they consist of aluminosilicate minerals, clays, porous glasses, microporous charcoals, zeolites, active carbons, or synthetic compounds that have open structures through which small molecules, such as nitrogen and water can diffuse.

* Often a result of an injury to the check ligament or to the structures at the back of the knee.

Often in adults, there may be a more or less regular pattern of white-edged dorsal scales appearing as white freckles all over the body up to moire-like structures in places, enhancing the shiny metallic appearance.
