Doris Lessing, the Persian-born, African-raised and London-residing novelist enjoys a writing career which has spanned more than 50 years. Critics have labeled her as Marxist, feminist, Sufist and even psycho-analyst. It is my contention to prove that latent Sufi characteristics are inherent in her works, and this premise marks a difference between my study and other research on Lessing. To pro...

The Escherichia coli protein SufI (FtsP) has recently been proposed to be a component of the cell division apparatus. The SufI protein is also in widespread experimental use as a model substrate in studies of the Tat (twin arginine translocation) protein transport system. We have used SufI-GFP (green fluorescent protein) fusions to show that SufI localizes to the septal ring in the dividing cel...

This article explores the influence of local concepts of matrilineal kinship and descent through women in the construction of a modern Sufi silsila (an authorized ‘chain’ of spiritual and genealogical ancestry) in Sri Lanka. Makkattar Vappa, a popular Sufi shaykh in the Tamil-speaking eastern region of the island, asserts hereditary maulana (sayyid) status as a member of the Prophet’s household...

The function of SufI, a well-studied substrate of the TatABC translocase in Escherichia coli, is not known. It was earlier implicated in cell division, based on the finding that multiple copies of sufI suppressed the phenotypes of cells with mutations in ftsI (ftsI23), which encodes a divisomal transpeptidase. Recently, sufI was identified as both a multicopy suppressor gene and a synthetic let...

The Tat system transports folded proteins across the bacterial cytoplasmic membrane and the thylakoid membrane of plant chloroplasts. In Escherichia coli substrate proteins initially bind to the integral membrane TatBC complex which then recruits the protein TatA to effect translocation. Overproduction of TatBC and the substrate protein SufI in the absence of TatA led to the accumulation of Tat...

The twin-arginine translocation (Tat) pathway in Escherichia coli transports fully folded and assembled proteins across the energy-transducing periplasmic membrane. In chloroplasts, Tat transport requires energy input only from the proton motive force. To elucidate the mechanism and energetics of bacterial Tat protein transport, we developed an efficient in vitro transport assay using TatABC-en...

The Tat (twin-arginine translocation) pathway is a Sec-independent mechanism for translocating folded preproteins across or into the inner membrane of Escherichia coli. To study Tat translocation, we sought an in vitro translocation assay using purified inner membrane vesicles and in vitro synthesized substrate protein. While membrane vesicles derived from wild-type cells translocate the Sec-de...

Dual-permeability models have been developed to account for the significant effects of macropore flow on contaminant transport, but their use is hampered by difficulties in estimating the additional parameters required. Therefore, our objective was to evaluate data requirements for parameter identification for predictive modeling with the dual-permeability model MACRO. Two different approaches ...

al-shab al-zarif, one of the most well-known poets of decadence age, is also a foremost borrower of religious texts in the field of worldly lyric. his lyrics are influence by quran, various religious texts, and notions of his sufi father, afif al-din telmesani. this study tries to examine the works of this prominent poet and analyze their intersexual relations to show his power in mixing religi...
