The film is an accurate account of the story told by the novel. Objectives/Student Outcomes Using this Learning Guide: Students in English classes can use the story as an example of allegory as it reveals historical truths and as an age-old literary technique for communication of important themes.
Placement of the. electrodes is dependent on the polarity of the medication being delivered. For example, dexamethasone. has a negative polarity. Therefore, the electrode containing dexamethasone will be placed over the. affected body part and attached to the negative charge in the electrical circuit. The negative current. repels the negative dexamethasone ions, driving them through the patient's skin.2,3 Conversely, lidocaine has a positive polarity so the electrode would be attached to the positive charge in the. electrical circuit.
Figure 4. In total, 62% of the retroperitoneal schwannomas (and none of the peripheral schwannomas) were positive for AE1/AE3 (1â4+); with a similar distribution to GFAP, keratin cocktail concentrated adjacent to the capsule, myxoid or degenerative areas, and in a perivascular distribution (a, b).f the peripheral schwannomas, only three of 22 were positive for GFAP and all were negative for AE1/AE3 keratin cocktail, so no further cytokeratins were evaluated on these tumors. Of the retroperitoneal schwannomas, 104/115 cases (90%) were positive for GFAP (14+) (Figure 3).
