Holograghic Brownian motion in three dimensional G\"{o}del black hole

By using the AdS/CFT correspondence and G\"{o}del black hole background, we study the dynamics of heavy quark under a rotating plasma. In that case we follow Atmaja (JHEP 1304, 021, (2013)) about Brownian motion in BTZ black hole. In this paper we receive some new results for the case of $\alpha^{2}l^{2}\neq1$. This case, we must redefine the angular velocity of string fluctuation. We obtain the time evolution of displacement square that angular velocity and show that it behaves as a Brownian particle in non-relativistic limit. In this plasma, it seems that relating the Brownian motion with physical observables is rather a difficult work. But our results match with Atmaja work in the limit $\alpha^{2}l^{2}\rightarrow1$.Comment: 16 page

Holograghic Brownian motion in 2+12+1 dimensional hairy black holes

In this paper, we investigate the dynamics of a heavy quark under the plasmas correspond to three dimensional hairy black holes. We utilize the AdS/CFT correspondence to study the holographic Brownian motion of this particle in different kinds of hairy black holes. For uncharged black hole at low frequency limit we derive analytic expressions for correlation functions and response functions and verify that the fluctuation-dissipation theorem holds in the presence of a scalar field in the metric background. In the case of charged black hole, we think that the results are similar to what derived for uncharged black hole.Comment: 15 page

The Murshids and the Messiahs: popular Messianism as a grassroots political movement in contemporary Iran

Messianic aspirations have been growing in Iran over the last two decades. With Mahmoud Ahmadinejad’s coming to power in 2005 and his apocalyptic language including his claim to have direct connections with the hidden Imam, a noticeable shift took place in the religious and political orientation of the Islamic Republic. Does this flow represent a return to traditional Shiism or a break from it? In what way do Messianic aspirations challenge the Shiite theology of salvation and existing clerical rule? This paper attempts to answer these questions by examining popular Messianism and Mahdism (Mahdaviyyat). While popular Messianism is a redemptive political movement, Mahdism is a political project to reappropriate the popular imagination through the messianization of politics and hastening of the Parousia. Mahdism reveals a discursive turn in which the Iranian Revolution and the Islamic Republic are imagined as a prelude to the Parousia and the appearance of the Hidden Imam. Nevertheless, it resulted in the ‘routinization of the Messiah’. The paper examines the Messianic imagination and the ways in which it challenges clerical rules and investigates the dilemma it poses for it

Post-Islamism: From Making Islam Democratic to the Politics of Myth

Post-Islamism has been suggested as an intellectual and political response by which Islam and democracy become compatible. However, post-Islamism is not a homogenous discourse and involves at least democratic and social democratic inclinations. For democratic post-Islamism, freedom, democracy, and human rights were master signifiers, whereas, for social-democratic post-Islamism and anticapitalist Muslims, justice is pivot of the intellectual constellation and religious criticism. Reviewing the main ideas and criticisms of the most recent post-Islamist intellectual discourses, this article investigates the ability of post-Islamism in addressing authoritarianism, inequality, and social injustice. Exploring the significance of the politics of myth for the meaningful intellectual and political endeavours, this article investigates the theological turn of the anti-capitalist Muslims and its significance for post-Islamism particularly in suggesting new understandings of the Qur’an. The article concludes that if Islamism is not seen primarily as a state ideology but as politics of myth, then post-Islamism requires to capture popular imagination

Expression of an innate immune element (mouse hepcidin-1) in baculovirus expression system and the comparison of its function with synthetic human hepcidin-25

Hepcidin is an innate immune element which decreases the iron absorption from diet and iron releasing from macrophage cell. In contrast to the chemical iron chelators, there has been limited effort applied to the specific use of hepcidin as a new drug for decreasing the iron overload. Hepcidin is produced in different biological systems. For instance, E-coli is used for human hepcidin expression, however, post-translational modification is impaired. We have used a simple baculovirus expression system (BES) to improve the hepcidin folding and activity. Hepcidin Messenger Ribonucleic acid (mRNA) was isolated from mouse liver cells and its complementary Deoxyribonucleic acid (cDNA) was produced and amplified. PFastBac HTB vector was used for recombinant bacmid production. Recombinant baculovirus was produced using SF-9 cell line. The mouse hepcidin-1 protein was expressed in a large quantity and functional tests were performed for this recombinant peptide. The yield of hepcidin in BES was 20 μg/mL and anti-histidine (anti-His) tag antibody was used for the confirmation of hepcidin on western blot nitrocellulose paper. Functional tests showed that mouse hepcidin accumulates iron in the macrophage cell line J774A.1 up to 63%. In addition, our data showed that the mouse hepcidin-1 has less toxicity compared to the synthetic human hepcidin-25 (p = 0.000). © 2011 by School of Pharmacy
