Journalistic sources and methods have usually been jealously guarded.
However, traditional eco-friendly reservoir operating methods have usually only considered the natural flow regime.
Furthermore, the standard algebraic methods have usually been used for systems not bigger than two degrees of freedom and do not appear to have been applied for frequency-dependent aerodynamics.
Physical and chemical methods have usually been successful in the synthesis of nanomaterials in large quantities in short periods of time, as well for specific size and shape.
Given a dataset of size n, grouped into K clusters, such methods have usually the goal to find the K centers of the clusters which minimize the mean squared distance between the data and their closest centers.
These methods have usually been classified into three categories (Durant & Mace 1994; Gaston et al. 2002) (i) subjective assessments; (ii) heuristic rules which are supposed to be an advance over purely subjective assessments; and (iii) quantitative risk modeling, which includes traditional PVA as a particularly simple (or degenerate) case.
While typing methods have usually been used to confirm epidemiological links, the rapid turn-around time of PCR-based methods makes them suitable for the prospective detection of clusters for further investigations [ 16].
In spite of the expected improvement of sensitivity to detect coevolution when biological information is used, methods have usually ignored this information due to the number and complex dependencies among biological properties.
In recent years, extraction methods have usually been based on liquid partitioning with ultrasonic extraction (USE), microwave-assisted extraction (MAE) or with the more advanced techniques of pressurised liquid extraction (PLE), or supercritical fluid extraction (SFE), which have replaced Soxhlet extraction [ 57, 58].
The modern method has usually been for the party or the dictator to have a private source of organized violence, Cheka or S.S., more ruthless than the normal ones.
