wuthering heights and the concept of marality/a sociological study of the novel
to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...
15 صفحه اولCharacterization of a tonB mutation in Erwinia chrysanthemi 3937: TonB(Ech) is a member of the enterobacterial TonB family.
The pectinolytic enterobacterium Erwinia chrysanthemi 3937 causes a systemic disease in its natural host, the African violet (Saintpaulia: ionantha). It produces two structurally unrelated siderophores, chrysobactin and achromobactin. Chrysobactin makes a large contribution to invasive growth of the bacterium in its host. Insertion mutants of a chrysobactin-defective strain were constructed and...

متن کاملIn vivo inhibition of TonB-dependent processes by a TonB box consensus pentapeptide.
The TonB box, a conserved pentapeptide sequence found in TonB-dependent colicins and receptors, is thought to interact physically with the TonB protein to facilitate TonB-dependent processes. Strains of Escherichia coli were treated in vivo with the synthetic TonB box pentapeptide Glu-Thr-Val-Ile-Val. The pentapeptide inhibited several TonB-dependent processes, including cell growth in low-iron...
