A double U-shaped orthogonal inducer for the alternating current field measurement (ACFM) is presented, which could extend the limitation of the direction of tested cracks and decrease the loss of magnetic flux compared to the single rectangular inducer.
(Facione, 1990, p. 5, quoted in Lai, 2011) While we think that our test is a useful step in the direction of testing biology-specific critical-thinking and science-process skills, there is a great need for a free, robust, and validated instrument to measure these skills in biology.
Apart from a lighthouse to the east-southeast which was not in view from the test site due to a lower elevation (and not lighting in the direction of the test site), there are no visible artificial light sources at all at the Faroese test site.
One case resembled that of Antiporus: species were either more or less divergent depending on the direction of the test.
The index corresponding to the minimum value of the ECOC output was selected as the predicted direction of the test data.
The test stimulus was shown after 50 ms for a duration of 105 ms in the center of the screen and subjects judged the moving direction of the test stimulus as in Experiment 1.
After a delay of either 50 ms or 500 ms, during which fixation was maintained, a test stimulus, also consisting of a RDK with a central red square, was shown for 105 ms. Next, subjects judged the moving direction of the test stimulus in a two alternatives forced choice (2AFC) manner using key presses, '1' for left and '0' for right.
These aggressive behavior patterns, easily recognizable and observed in previous work with other species of Cataglyphis [19], [21], included threatening with open mandibles, formic acid projection (in which formic acid poison was sprayed in the direction of the test stimulus), dismemberment attempts, and biting.
