Azadirachtin (Aza) used as insecticide due to inhibiting growth of insects and preventing them from feeding on plants. To understand the effects of contamination of this insecticide on phototrophs, and to determine the responses of these organisms against these insecticides are extremely important in understanding how the ecosystem is affected. In this study, chlorophyll-a amount, OD 560 and antioxidant parameters (total SOD, APX, GR, Proline, MDA and H2O2) were determined in order to understand the effect of Aza on Arthrospira platensis Gomont. Aza was applied between 0–20 μg mL−1 concentrations for 7 days in the study. Enzyme analysis was conducted at the end of the 7th day. There was a statistically significant decrease in the absorbance of OD560 and the chlorophyll-a content in A. platensis cultures exposed to the Aza (0–20 μg mL−1) during 7 days due to the increase in pesticide levels. SOD activity decreased at 8, 16 and 20 μg mL−1 concentrations; GR enzyme activity showed a significant decrease compared to the control at a concentration of 20 μg mL−1. APX activity did not change significantly compared to control. The MDA content increased significantly at 16 and 20 μg mL−1 concentrations. The H2O2 content significantly increased at 12, 16 and 20 μg mL−1 concentrations (p < 0.05) while the free proline content decreased at 4 μg mL−1 concentration (p < 0.05). As a result, regarding the Aza concentrations used in this study may be a step to prevent pesticide pollution in the environment.

The Church

This concluding chapter examines the structure of the composite books 11 and 12, in which the prophesied destruction of Eden corresponds, antithetically, to the building of Pandaemonium at the beginning of Paradise Lost in book 1. After the Fall, Eden might become a temple, oracle site, a grove of pagan rites, goal of pilgrimage—it has already, at the moment that Satan invades it in book 4, been compared to the sheepfold of the Church, prey to thieves, a Church too rich to escape corruption. In books that predict the rise of empires, God dissociates his cult from power and wealth, closing down and eventually washing away Eden, lest it become another Pandaemonium—a haunt of foul spirits.

Ulysses and the Devils: The Unity of Book 2

Trojan War

This chapter focuses on book 2 of Paradise Lost. In book 2, Milton continues the story of the demilitarization of the fallen angels and of his epic more generally when he bases all of its action around the figure of Ulysses, the hero of eloquence and fraud, whose own epic comes in the aftermath of the Trojan War. The chapter demonstrates that the Odyssey, imitated and parodied in Satan's voyage through Chaos to God's newly created universe in the book's last section, is just one of the classical stories about the career of Ulysses that Milton evokes as models for its different episodes. The various parts of book 2 are held together by this pattern of allusion, as well as by the Odyssean figures of Scylla and Charybdis, the emblem of bad choices, or of loss of choice itself.
