We map tractable satisfiability classes to tractable entailment classes, including hierarchies of tractable problems; and show that some initially promising conditions for tractability of entailment, proposed by Esghi (1993) and del Val (1994), surprisingly only identify a subset of renamable Horn.
So how to explain that, despite such promising conditions, on 9 February, Tony Abbott was forced to walk into the meeting room of his political party to receive judgment on his leadership?
Much further in the past, billions of years ago, when the ancient rivers of Mars still flowed, its air was thicker and its volcanoes spewed fresh lava stinking with fertile gasses, the planet may have given life to creatures who took advantage of these promising conditions.
Mr. Aquino, known by his nickname Noynoy, inherits the mantle of honesty from his mother, the late Corazon Aquino, but also memories of her failure to bring lasting improvements in governance, even in the promising conditions for change that followed the fall of Marcos.
This new experimental approach for SWCNs growth provides promising conditions for maximizing yields and generating selected tubular configurations.
The most promising conditions were obtained with the Carboxen-polydimethylsiloxane fiber in the headspace of the aqueous solution that contained the dissolved powder.
The potential promising conditions for chromizing treatment were: adding 1% NH4Cl and 1% LaCl3, maintaining the test temperature at 1000 °C for 8 h.
The comparison with the experimental data showed that the model was reliable with respect to the identification of the operating conditions maximizing the selectivity, i.e. the most promising conditions for a monoclonal antibody variant separation.
In vivo environments like this may provide the most promising conditions for testing the sdiA-dependence of a particular gene.
