- چکیده:
- چکیده انگلیسی: In this study, a new N3-Schiff base ligand (L) was obtained from via condensation reaction of diethylenetriamine and (Z)-3-(4-(dimethylamino)phenyl)acrylaldehyde (1:2 ratio). Then some its new five coordinated HgLX2 complexes inwhich X is halide/pseudohalide were synthesized. The ligand and its complexes were characterized by various analysis tools such as FT-IR, 1H and 13C NMR, UV–visible, thermal analyses and molar conductivity measurements. Based on the spectral data and conductivity measurements, all the newly prepared compounds were found to be non-electrolyte. Moreover some mercury complexes were prepared in nano-structured size by sonochemical method and confirmed by X-ray powder diffraction method (XRD) and scanning electron microscopy (SEM) analyses. The Schiff base and its mercury complexes have been screened for their in-vitro antibacterial activities (Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Bacillus subtilis) and antifungal activities (Candida albicans and Aspergillus oryzae) using well diffusion method. Furthermore, thermal behaviors of ligand and its mercury complexes were evaluated in the range of room temperature to 1000°C under nitrogen atmosphere. The Schiff base ligand and complexes were decomposed completely via 2 to 5 thermal steps.

- چکیده:
- چکیده انگلیسی: This article studies Sir Walter Scott’s use of the family-as-nation trope in Ivanhoe and Anne of Geierstein. The importance of this trope in his figuration of nationhood is discerned by carrying out a close reading of the texts and placing them in their historical context, which primarily consists of a comparison with Edmund Burke and Maria Edgeworth. Consequently, his position is revealed as being between that of Burke and Edgeworth and the significance of his status as a non-English British writer is seen as a source of his opinions. His use of father-son and father(-figure)-daughter couples allows him to examine the existence of multi-lateral ethnicities as well as to express his attachment to a patriarchal view of descent and filiation, whilst simultaneously permitting hybridization through marriage to foreign women. By comparing the manner in which he uses the trope in the two novels, it is seen that his opinion on hybridization changes from one that permits men to be hybrids to one that restricts it to women. Thus Scott permits filiation to both men and women, but limits affiliation to women.
