Usually a citadel was a " mini fortress " within the larger fortress, sometimes designed as a reduit, but more often as a means of protecting the garrison from potential revolt in the city.

Usually, shareware differs from free / open-source software in that requests of voluntary shareware fees are made, often within the program itself, and in that source code for shareware programs is generally unavailable in a form that would allow others to extend the program.

Usually, the funnel cloud begins causing damage on the ground ( becoming a tornado ) within a few minutes of the RFD reaching the ground.

Usually basalt is too hot and fluid to build up sufficient pressure to form explosive lava eruptions but occasionally this will happen by trapping of the lava within the volcanic throat and build up of volcanic gases.

Usually, special vent tubes allow air to escape from the chamber as it fills or enter as it empties, maintaining atmospheric pressure within the float chamber ; these usually extend into the carburetor throat.

Usually, within the lower atmosphere ( the troposphere ) the air near the surface of the Earth is warmer than the air above it, largely because the atmosphere is heated from below as solar radiation warms the Earth's surface, which in turn then warms the layer of the atmosphere directly above it, e. g., by thermals ( convective heat transfer ).

Usually, the best results appear within the first and second year of therapy.

Usually a taxi will respond and arrive within 5 minutes.

Usually hidden beneath a lip, is the entrance to the real nest within, a cup of grass or sedge, nearly as large as the nest of a Blackbird, lined with leaves of oak, beech or other trees.

Usually, like himself, they had enjoyed the privilege of university, not then within the purview of the lower classes.

Usually, the time it takes to evacuate is measured to ensure that it occurs within a reasonable length of time, and problems with the emergency system or evacuation procedures are identified to be remedied.

Usually these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county.

Usually some memory registers ( triggering ports ) within common address space, perform an assigned operation when the instruction references them.

Usually that offence will be theft, but most jurisdictions specify others which fall within the ambit of burglary.

Usually the aortic and mitral valves are incorporated in valve studies within a single degree of freedom.

Usually the sole object in free-flight is flight duration, and one of the sport ’ s fascinations and challenges is to design the most efficient aircraft within the various competition limits on such parameters as minimum weight, maximum wing area and motive power.

Usually placed in the order Caprimulgiformes, another recent study has cast doubt on the frogmouths ' placement within that order,

Usually the tube is praised for simplicity, but for precision measurements of charged low energy particles the electric and the magnetic field in the flight tube has to be controlled within 10 mV and 1 nT respectively.

Usually, when it occurs in infants the condition resolves itself within days and with no treatment.

Usually situated on dendritic spines, or neuronal membrane protrusions on which glutamate receptors and postsynaptic density components are concentrated, excitatory synapses aid in the electrical transmission of neuronal signals.

Usually DNA damage, if too severe to repair, leads to programmed cell death, but if the programmed cell death pathway is damaged, then the cell cannot prevent itself from becoming a cancer cell.

Usually, a flash cell is smaller than an equivalent EEPROM cell and is therefore less expensive to manufacture.

Usually an electrolytic cell ( consisting of two electrodes, electrolyte, and external source of current ) is used for electrodeposition.

Usually, the government agency charged with carrying out an execution, normally the state's Department of Corrections or the U. S. Bureau of Prisons in federal cases, has a limited time frame, normally about 60 days, from the date the warrant is signed, to complete the execution process, or the warrant expires and the condemned person is returned to the death row cell, where he or she will await another execution date.

Usually, a suitable dye, such as Giemsa, is applied after cells have been arrested during cell division by a solution of colchicine.

Usually, self reactive B cells remain anergic in the periphery without T cell co-stimulation.

Usually they also give rise to a sheet of cross-like microtubules that runs down the center of the cell and in some cases projects past the end.

Usually the various checkpoints in the cell cycle take care of genomic integrity via highly conserved redundant mechanisms that are important for maintaining cellular homeostasis and preventing tumorigenesis.

Usually, only one cell of a memory is affected, although high energy events can cause a multi-cell upset.

Usually information on the top header of a table and side header will " meet " in the middle at a particular cell with information regarding the two headers it is collinear with.

Usually the starting point is an undefined heterogeneous group of molecules in solution, such as a cell lysate, growth medium or blood serum.

Usually this cell would divide into two XY cells, but in rare occasions the cell may divide into an X cell and an XYY cell.

Usually this is very bad for the cell, resulting in extreme damage and possible death of the cell.

Usually a load cell is placed between the shaker and the structure to obtain the excitation force.

Usually, the initial design of a standard cell is developed at the transistor level, in the form of a transistor netlist or schematic view.

Usually this contact covers the entire rear side of the cell, though in some cell designs it is printed in a grid pattern.
