abu'l faid thawban ibn ibrahim, known as dhu'l-nun al-misri, is one of the most prominent figures in the history of sufism.  he is certainly considered as one of the top ten sufi scholars throughout the history. recognition of his status and his unheard words, as an effective criterion of western islam-world, seems necessary to recognize islamic sufism, for most of resources appreciat...

many scholars at the present and in the past have tried to portray abulfida’ isma‘il ibn ‘umar ibn al-kathir ad-dimashghi as a truthful historian and without any fanaticism. however, the content of his “al-bidayah wa n-nihayah” indicates his utmost religious fanaticism, hiding and distorting truths, lack of politeness in writing, turning away from islamic ethics and even contradicting himself a...

although critics and novelists have not paid enough attention to the second person point of view, it has a lot of potentials for picturing the deepest parts of human mind. most important types of this model are: 1. narratives in which the narrator, the protagonist and the addressee are the same; 2. narratives in which the narrator is separate from the protagonist/addressee. reviewing the comple...

besides being a literary work, the novel curse of the land (nefrin-e zamin) is a social document. in this great work, al-e ahmad intends to give a social analysis of this own era, and warn his readers against the devastating consequences of modernity. viewed from this perspective, it is regarded as his most sophisticated work representing his social thoughts and theories. in this paper an effor...

The polar flagellum of Vibrio alginolyticus is rotated by the sodium motor. The stator unit of the sodium motor consists of four different proteins: PomA, PomB, MotX and MotY. MotX and MotY, which are unique components of the sodium motor, form the T-ring structure attached to the LP ring in the periplasmic space. MotY has a putative peptidoglycan-binding motif in its C-terminal region and MotX...

The recombinant expression of soluble proteins in Escherichia coli continues to be a major bottleneck in structural genomics. The establishment of reliable protocols for the performance of small-scale expression and solubility testing is an essential component of structural genomic pipelines. The SSGCID Protein Production Group at the University of Washington (UW-PPG) has developed a high-throu...

BACKGROUND Functional Genomics, the systematic characterisation of the functions of an organism's genes, includes the study of the gene products, the proteins. Such studies require methods to express and purify these proteins in a parallel, time and cost effective manner. RESULTS We developed a method for parallel expression and purification of recombinant proteins with a hexahistidine tag (H...

A practically simple top-down process for the exfoliation of graphene (GN) and few-layer graphene (FLG) from graphite is described. We have discovered that a biocompatible amphiphilic pyrene-based hexahistidine peptide is able to exfoliate, functionalize, and dissolve few layer graphene flakes in pure water under exceptionally mild, sustainable and virtually innocuous low intensity cavitation c...
