Initiation of DNA replication from the Escherichia coli chromosomal origin is highly regulated, assuring that replication occurs precisely once per cell cycle. Three mechanisms for regulation of replication initiation have been proposed: titration of free DnaA initiator protein by the datA locus, sequestration of newly replicated origins by SeqA protein and regulatory inactivation of DnaA (RIDA...

Luminescence spectra at 85 K have been recorded for a series of chromium (III) complexes with alkyliminodiacetates (RIDA) of the form K [ C r ( R I D A ) 2 ] , R = M(methyl) , E(ethyl) , n-P(n-propyl) , i-P(isopropyl), n-B-(n-butyl), and t-B (t-butyl). Infrared and far infrared spectra of room temperature samples were also recorded. All of the RIDA complexes exhibited the vibronic spectrum, wit...

The majority judgment theory is developed by Michel Balinski and Rida Laraki for social choice [2, 3]. In this paper we will show that majority judgment theory does not always yield a majority choice, is winner and rank inconsistent and the median based majority judgment may yield paradoxical results.

Chromosomal replication is initiated from the replication origin oriC in Escherichia coli by the active ATP-bound form of DnaA protein. The regulatory inactivation of DnaA (RIDA) system, a complex of the ADP-bound Hda and the DNA-loaded replicase clamp, represses extra initiations by facilitating DnaA-bound ATP hydrolysis, yielding the inactive ADP-bound form of DnaA. However, the mechanisms in...

A new species, Scymnus (Scymnus) contortubus Rashid, Chen & Wang, sp. n., is described and illustrated from Pakistan. A diagnosis, remarks, illustrations, and a distribution map are provided of the new species and its most similar congener, S. (S..) nubilus Mulsant.

the relations of abbasid state and bizans empire were more hostile in rashid era. on the other hand, the good understanding of abbasid and westerns was one of the most important reasons of this hostility because they were very frightened of their cooperation and this factor continued until mamun era. great sharlman succeeded his father, pepin, and in this era, his relation with ghostantaniyyeh ...
