By the time the board was deciding on the validity of these trades, it was already over - months before the actual collapse.
However, trading innovations fail due to a lack of effective management, reasons unrelated to the individual talents of traders, financial engineers, and IT professionals or to the validity of the trading/investment strategy.
Thus, our results challenge the general validity of the trade-off hypothesis for virulence evolution, and stress the need of considering the effect of both the host and parasite genotypes in analyses of host-parasite interactions.
The general validity of the trade-off hypothesis and of its central assumption of a positive correlation between parasite multiplication and virulence has been questioned for more than a decade.
Thus, to test the validity of the trade-off hypothesis assumptions for the Arabidopsis-CMV host-parasite system, in this report we have analysed the interaction of three CMV isolates with twenty one wild genotypes (referred to as accessions) of Arabidopsis.
To overcome these limitations and to test the general validity of the trade-off hypothesis assumptions for a plant-virus system, we have analysed the interaction of three CMV isolates with 21 A. thaliana accessions.
This is the step where a team tests the validity of the proposed trading system in addition to another review of the correctness of the units.
This study was designed to test the feasibility and face validity of the composite time trade-off (composite TTO), a new approach to TTO allowing for a more consistent elicitation of negative health state values.
Persuasive opportunities: the Internet can be used to reassure (potential) buyers about the reliability of the trade and the validity of the animal, plant, and product sold.
Fire departments and trade unions questioned the validity of existing studies from outside Germany because of specific differences in the professional career.
