The Southern timber market is the major source of both softwood and hardwood pulpwood in the US. In 1997, three-fourths of total US pulpwood production was produced in the region. The locations of pulpmills and fiber sources determine the patterns of pulpwood trade between the states. Prediction of trade is important for understanding subregional pulpwood markets in the US South and for timber ...

the relationship between technology and international competitiveness dates back to the neo-technological trade theories of the 1960s. this approach considers difference in technology as the primary motive for difference among nations in terms of trade performance. the technology gap approach emphasizes inter-country differences in innovativeness as the basis for international trade flows. the ...

Despite intergovernmental calls for greater policy coherence to tackle rising non-communicable diseases (NCDs), there has been a striking lack of coherence internationally and nationally between trade and health sectors. In this commentary, I explore the arguments by Lenucha and Thow in relation to barriers for greater coherence for NCDs, apply them to regional trade ag...

Acid mine drainage (AMD) containing high concentrations of iron and sulphate, low pH and variableconcentrations of heavy metals leads to many environmental problems. The concentrations of Cu and Mnare high in the AMD of the Sarcheshmeh porphyry copper mine, Kerman province, south of Iran. In thisstudy, the bio-remediation of Cu and Mn ions from acid mine drainage was investigated using two nati...

Slope stability is one of the most important issues in open pit mining design. The main purpose of any open pit mine design is to propose an optimal excavation configuration, considering safety, ore recovery and financial return. An accurate pit slope design which accounts for the mine geology, structural geology, rock mass properties, and hydrogeology models of the mine area, drastically enhan...

Sustainability assessment has received numerous attentions in the mining industry. Mining sustainability includes the environmental, economic, and social dimensions, and a sustainable development is achieved when all these dimensions improve in a balanced manner. Therefore, to measure the sustainability score of a mine, we require an approach that evaluates all these three dimensions of mining ...
