Of course, documenting allopolyploidy is relatively easy and involves demonstrating that the hybrids have twice as many chromosomes (or more) as the parental species and that they retain fixed polymorphisms at protein-coding loci as documented by either protein studies, which were common in the 1980 and 1990s, or DNA sequencing/fingerprinting, which are the current methods of choice.
Convergent validity involves demonstrating that theoretically related dimensions of an instrument are highly correlated and was examined by correlating the items with SF-36 domains.
The first studies showing that GABA plays a critical role in pain transmission involved demonstrating that baclofen, a GABA-B receptor agonist, blocked pain in preclinical models of acute and chronic pain [ 38].
Investigating thermal comfort conditions in outdoor urban spaces, has thrown some light on the complexity of the issues involved, demonstrating that a quantitative approach is insufficient in describing comfort conditions outdoors.
Additionally, the improvements are more significant with more objectives involved, demonstrating that the proposed algorithm can serve as a universal, high performance algorithm for the multi-objective optimization of wind turbine blade design.
In that case, Baze v. Rees, the court left room for challenges to execution methods that involve a demonstrated risk of severe pain compared with available alternatives.
This is a step that involves considerable risks, as demonstrated, for example, by the decline of the neighbourhood associations in Barcelona and so many other Catalonian cities after 1979.
In intensive care units, the efficacy and favourable cost/benefit ratio of setting up a voluntary strategy for the prevention of MRSA infections that involves screening have been demonstrated [ 25- 27].
The performance of the calorimeter in selecting resonant states that involve photons is demonstrated.
Although this systematic review demonstrates that the initial results from the use of expandable nails are promising, we would caution that most of the studies involved demonstrated numerous methodological weaknesses.
