The classical long-period method does not stick strictly to stationary prices.
When this premise (the slowness of the changes of long-period prices) does not hold, given the unsatisfactory nature of the marginal approach, 'the long-period method appears to be the only acceptable one available at present' (Kurz and Salvadori 1995, p. 341).
We therefore successfully deprived female flies of sleep over a long period via two independent methods; males were deprived of sleep using the mechanical stimulus but not the light stimulus.
Licensing to a particular dominant operator for a long period has been the traditional method for spectrum assignment in order to avoid interference and collisions.
This method requires a long period of hospitalization and accurate control of fracture alignment with frequent radiographs and adjustments in traction as needed.
A disadvantage of this method is the long period of spiking over 10 days, while manual spiking needs only 2 h.
This method exploits the long period content of the broadband seismic record (200 sec- 1000 sec) preceding the arrival of the surface waves.
Disadvantages of this method include the long period of immobilization of the wrist, the need for a second operation to remove the hardware, potential attritional damage to the extensor tendons, difficulty in reducing and stabilizing the volar fragments of the distal radius, and the risks related to overdistraction of the radiocarpal joint (CPRS, finger functional impairement) [3, 4].
Based on the knowledge that concrete structures in the mid-west of Inner Mongolia are subject to erosion caused by the wind and sand environment over a long period of time, sediment-air injection method was used for an experimental study into erosion on concrete in the wind-blown sand environment, and then involving analysis of concrete erosion features and erosion behavior law.
Though patients were not told about these allocations until after consent had been given, the long period of recruitment and cluster-randomised method meant it was not always possible to blind those recruiting patients.
The enclosure of commons and open fields was carried out by many different methods over a long period of time.
