the objective of this paper is to explore the effect of financial crisis on trade flows of steel industries in the major asian-pacific steel producing countries. using a static and dynamic panel data analysis, we test the hypothesis that the global financial crisis has a negative effect on asia-pacific bilateral steel trade flows. we also examine the role of regional trade integration in bilate...

OIC members have much potential in their economic development. Therefore, their economic integration leads to more increment for partners and deal with global system as a unique organization. Consequently, studying the convergence of OIC members and their encountered challenges has especial importance which can assist the policy makers to develop their commercial relationship and consequent...

the gravimetric method is one of the most effective ways for the detection of subsurface structures such as tunnels, faulting, mineral deposits with the required density difference, especially in areas with rough topography and tectonized formations. it is possible to provide a more suitable model for better interpretation of the gravity anomaly. inverse modeling of gravity data is the most eff...

Coastal Fars gravimetry project in Fars province was carried out to find the buried salt domes and to determine characteristics of faults in this area. The Lavarestan structure was covered by 4203 gravimetry stations in a regular grid of 1000*250 m. Depth structural model of this anticline made in previous studies was based on geological evidences and structural geology measurements. In order t...

The experimental study and modeling of gravity drainage during Water Alternative Gas Injection, WAG process, in carbonate rock for one of the Iranian off-shore reservoir at lab-scale were carried out. The mechanism of gravity drainage during the WAG process, and its contribution to the oil recovery in the fract...

James L. Anderson analyzed the conceptual novelty of Einstein’s theory of gravity as its lack of “absolute objects.” Michael Friedman’s related concept of absolute objects has been criticized by Roger Jones and Robert Geroch for implausibly admitting as absolute the timelike 4-velocity field of dust in cosmological models in Einstein’s theory. Using Nathan Rosen’s action principle, I complete A...

the role of distance as border effects between trade partners has been created challengeable discussions in gravity model literature for international economists and lead to different theoretical aspects for measuring and modeling of it in recent years. moreover, the necessity of non-linear method for estimation of gravity model has been perfectly agreed. the importance of this study is the est...
