   Vena contracta is defined as the narrowest portion of the regurgitant jet, seen at its origin. In all of the cases, it was assumed that the MR severity was downgraded by general anesthesia because of reduced afterload conditions. In cases where MR was determined to be trace, mild, or moderate, the afterload was manipulated by bolus injections of phenylephrine to approximate the preanesthesia, awake blood pressure. The final MR grade was assigned after this maneuver was completed. If conflicting results were observed for different criteria, the reviewing anesthesiologist made a judgment as to the final grade of MR.

   Through the above, it is clear that the students of the experimental group who studied the unit of similarity of triangles according to the model (4mat) have outperformed the students of the control group who studied the same unit in the traditional way in the results of the systemic thinking measurement. It was also found that the students of the experimental group have been developing their geometric tendencies more than the students of the control group, and this is due to the use of the (4mat) model. It provided the opportunity for students to overcome many difficulties by giving them the opportunity to discover data for themselves, because it allowed them to recognize similar triangles through their own thinking patterns and transition as the information discovered remains more trace than the information that is taught to students in the traditional way.

   As indicated in Chomsky (1982), the empty element in (26a) has an antecedent with an independent 0-role and is therefore PRO rather than trace. Subjacency is violated, but nevertheless PRO and its antecedent can be coindexed, as is generally possible for anaphors, apart from trace (in (26c), the coindexing of they and each other violates subjacency). In (26b), the antecedent of the empty element is in a non-0-position, so the empty element is trace. Subjacency is violated as in (26a), but in this case, the sentence is ungrammatical.⁹ Thus subjacency appears to be a property of the rule Move α, not of other indexing mechanisms. If this conclusion is correct, then clearly we will have to distinguish between the indexing mechanism at work in (25a) or (26b) -- i.e. Move α -- and the one at work in (25b-c) or (26a,c).
