The limits of the Russian-Iranian strategic alliance: its history and geopolitics, and the nuclear issue
(Routledge Journals, Taylor & Francis Ltd, 2008-03)
The Russian and Iranian governments define their relations as "very close" and "strategic" in many areas. The frontiers of this cooperation, in geopolitical terms, include the south Caucasus, central Asia, Afghanistan, and ...
Numerical calculations of relativistic electron drift loss effect
(Amer Geophysical Union, 2008-09-09)
It has been suggested that drift loss to the magnetopause can be one of the major loss mechanisms contributing to relativistic electron flux dropouts. In this study, we examine details of relativistic electrons' drift ...
On the identification of microstretch elastic moduli of materials by using vibration data of plates
(Pergamon-Elsevier Science LTD, 2008-06)
In the present work, the vibration problems of rectangular plates modeled by Eringen's microstretch theory are investigated for the identification of the upper bounds of the microstretch moduli of the plate material. The ...
Afghanistan's security: Political process, state-building and narcotics
(Wiley-Blackwell, 2008-06)
Establishing political authority and constructing a state instrument would increase trust, which would contribute to stability.1 The lack of political institutions necessary for stability encourages the interference of ...
Poly (styrene) latex/modified na-activated bentonite nanocomposite films: a fluorescence study
(Elsevier Science BV, 2008-12)
We studied film formation of composites of surfactant-free polystyrene (PS) nanoparticles and modified Na-activated bentonite (MLB), by steady state fluorescence (SSF) technique. The films were prepared from a mixture of ...
The composition of acids in bitumen and in products from saponification of kerogen: Investigation of their role as connecting kerogen and mineral matrix
(Elsevier Science BV, 2008-11-03)
In order to obtain more information and to understand the nature of relation between organic and mineral matter in oil shales, the compositions of soluble bitumen fractions obtained by extraction from Bulgarian oil shales ...
Component resolved IR bleaching study of the blue LM-OSL signal of various quartz samples
(Wind-J Wojewoda Publ Co, 2008-01-01)
The present work provides an initial component resolved analysis concerning the effect of infra-red (IR) exposure at elevated temperatures on the blue LM-OSL signal of quartz (stimulated at 470 nm). The study was performed ...
The conformal Penrose limit: back to square one
(IOP Publishing LTD, 2008-08-21)
We show that the conformal Penrose limit is an ordinary plane wave limit in a higher dimensional framework which resolves the spacetime singularity. The higher dimensional framework is provided by Ricci-flat manifolds which ...
Weakly non-linear waves in a fluid-filled elastic tube with variable prestretch
(Pergamon-Elsevier Science Ltd, 2008-11)
In the present work, by utilizing the non-linear equations of motion of an incompressible, isotropic thin elastic tube subjected to a variable prestretch both in the axial and the radial directions and the approximate ...
LM-OSL thermal activation curves of quartz: Relevance to the thermal activation of the 110 degrees C TL glow-peak
(Pergamon-Elsevier Science Ltd, 2008-01)
The thermally activated characteristics (TAC) of the linearly modulated optically stimulated luminescence (LM-OSL) signals of seven quartz samples from different origin were studied relative to the TAC of their respective ...
