We focused our research on the technique identified by Ruiz-Primo et al. (2011) as the most common technique present in the research literature, which they identified as "conceptually oriented tasks + collaborative learning".
The antioxidant activity was also studied by some experiment in vitro, and the bioactive substances were isolated using chromatographic techniques and identified by NMR spectroscopic methods.
The main chemical constituent of petroleum ether and ethyl acetate extracts were also isolated using chromatographic techniques and identified by NMR spectroscopic methods.
Two other studies (Chou and Lee 2001; Nakamura et al. 2011) reporting on both open and arthroscopic techniques were identified by the electronic search.
Some techniques were identified by the researchers as characterizing MME (e.g. Markov models), while others at the same level of sophistication in terms of mathematics were not (e.g. Cox regression).
In general, conventional impedance-based techniques identify damage by comparing "current" impedance signals with "baseline" ones obtained from the pristine condition of a structure.
The latter three strains were isolated by dilution plating technique and identified by morphological characterization.
The need for a new compression technique was identified by the Pistoia Alliance who commissioned an open innovation contest to find one.
