nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (anfo) explosive at the sungun surface mine, located in the northwest of iran. the pollutants were monitored during some blasting operations at the mine. it was concluded that the gases and dust clouds initially went up to the ...

One of the main concerns of all industries such as mine industries is to increase their profit and keep their customers through improving quality level of their products; but increasing the quality of products usually releases air pollutants. Nowadays the management of air pollutant emissions with harmful environmental and health effects is one of the most pressing problems. In this paper, auth...

The paper studies the effect of terms of trade fluctuations on equilibrium debt position of a small open economy. I develop a simple model of a small open economy producing exportable and nontradable goods to investigate the effects of terms of trade shock assuming that terms of trade follow two state Markov switching process. Under this process, permanent terms of trade shock means change of r...

The E. coli MinDE oscillator is a paradigm for protein self-organization and gradient formation. Previously, we reconstituted Min protein wave patterns on flat membranes as well as gradient-forming pole-to-pole oscillations in cell-shaped PDMS microcompartments. These oscillations appeared to require direct membrane interaction of the ATPase activating protein MinE. However, it remained unclear...

For enhancing low lumination image of underground mine tunnel, a hybrid local histogram equalization with partial differential equation is proposed to combine a local histogram equalization and total variation method with edge-stopping function via partial differential equation. The local histogram equalization is to enhance contrast of image with keeping shape and edge, while total variation m...

sarcheshmeh copper mine, with the final reserves of 828 million tons of sulfur ore and average grade of 0.74%, is known to be the largest open pit of iran and most probably the second largest copper mine in the world. this mine is located in the seismotectonic zone of central-iran, and 23 km away from the 150 km long rafsanjan active fault.in this study the vulnerability of the west wall of the...

Quebec’s asbestos mines have operated for 130 years and made Quebec a world leader in export of asbestos over the past century. Even though the scientific evidence was overwhelming that use of asbestos was causing epidemics of asbestos-related diseases and death, the Quebec and Canadian governments continued to give the asbestos industry unquestioning financial and political backing. This legit...

This paper investigates the impact of the US and China’s foreign aids to Africa on trade flows between donor and recipient countries. Evidence from the gravity model estimates reveals that the two donors’ exports are strengthened by their aids to African partners. Interestingly, China’s aid shows a positive effect on its total volume of trade and imports from Africa, while the aid from the US e...

This paper argues that the growing US trade de…cit has caused the decline of the WTO and the rise of regional trade agreements. A country in de…cit prefers to retain market power against countries with a large surplus. Multilateral cooperation restricts its choice. This notion is formalized in a three-country game in which countries negotiate multilaterally and, if that fails, bilaterally. The ...
