This paper is intended as an investigation of historical transformation of a tribal confederation in Iran, the Afshars in Orumiyye province from the seventeenth to the nineteenth century. It has been said that a tribal resurgence was dominant tendency in eighteenth century, but no studies have ever tried to analyze the features of the tribes and their relation with local society in these days. Main arguments are following: 1. The Afshars who was a member of the Qizilbash confederation, migrated to Orumiyye at the first half of the seventeenth century in order to defend the Ottoman border and hold governorship of the province until the end of the Safavid period. 2. In the eighteenth century they had closer ties with the local society and became an independent power. Some new tribes joined the Afshar confederation and some Kurdish tribes also supported them on their military expeditions. 3. At the same time the tribal elites chose to live in the Orumiyye city and hold some offices of local government not only military ones but also civil ones such as vakil or mostowfi, and some also became ‘ulama. Some tribesmen poured into the city and behaved themselves like hooligans 4. The tribal chiefs got a amass of land by land exploitation and occupation of waqf land and some tribesmen settled in villages as farmers. 5. Under the Qajars they lose the governorship, but they found an opportunity to get high ranks in the modern army as the result of military reform and retained their power in the province.

BackgroundCell growth rate reflects an organism’s physiological state and largely relies on the ability of gene expression to respond to the environment. The relationship between cellular growth rate and gene expression remains unknown.ResultsGrowth rate-coordinated changes in gene expression were discovered by analyzing exponentially growing Escherichia coli cells cultured under multiple defined environments, in which osmotic pressure, temperature and starvation status were varied. Gene expression analyses showed that all 3,740 genes in the genome could be simply divided into three clusters (C1, C2 and C3), which were accompanied by a generic trend in the growth rate that was coordinated with transcriptional changes. The direction of transcriptional change in C1 indicated environmental specificity, whereas those in C2 and C3 were correlated negatively and positively with growth rates, respectively. The three clusters exhibited differentiated gene functions and gene regulation task division.ConclusionsWe identified three gene clusters, exhibiting differential gene functions and distinct directions in their correlations with growth rates. Reverses in the direction of the growth rate correlated transcriptional changes and the distinguished duties of the three clusters indicated how transcriptome homeostasis is maintained to balance the total expression cost for sustaining life in new habitats.

We evaluated electronic structures and magnetic moments in Co3FeN epitaxial films on SrTiO3(001). The experimentally obtained hard x-ray photoemission spectra of the Co3FeN film have a good agreement with those calculated. Site averaged spin magnetic moments deduced by x-ray magnetic circular dichroism were 1.52 μ B per Co atom and 2.08 μ B per Fe atom at 100 K. They are close to those of Co4N and Fe4N, respectively, implying that the Co and Fe atoms randomly occupy the corner and face-centered sites in the Co3FeN unit cell.

We show that antipodal sets of symmetric R-spaces have the following properties. Any antipodal set is included in a great antipodal set and any two great antipodal sets are congruent.

We evaluated the capabilities of an in situ method for measuring copper isotopes of cubanite using UV-fs-LA-MC-ICP-MS. A comparison of the UV-fs laser results with those obtained from the NIR-fs laser system shows that there is obviously an improvement in the precision (<0.10‰, 2SE) when using the UV-fs laser. In both wavelength modes, matrix-matched standards are required for reliable in situ copper isotope analysis of cubanite. This method was applied to determinations for copper isotopes of minute cubanite grains in a skarn ore. Copper isotopic ratios of cubanite grains near a weathered surface of the sample are lower than those of intact cubanite grains within the sample, suggesting that selective leaching of heavier copper isotope in primary minerals occurred during weathering.
