1 The term ‘‘WTC-related’’ was not included in the proposed definition of acute traumatic injury in the notice of proposed rulemaking, 80 FR 54746 (Sept. 11, 2015), but has been added in the final rule to clarify specific usage in the WTC Health Program and better parallel ‘‘WTC-related musculoskeletal disorder’’ on the List. The Administrator finds that revising the term results in no substant...

Leaf litter decomposition is the key ecological process that determines the sustainability of managed forest ecosystems, however very few studies hitherto have investigated this process with respect to silvicultural management practices. The aims of the present study were to investigate the effects of forest management practices on leaf litter decomposition rates, nutrient dynamics (C, N, Mg, K...

Unasylva 230, Vol. 59, 2008 The Intergovernmental Panel on Climate Change’s fourth assessment report (IPCC, 2007) estimated that the forest sector contributes 17.4 percent of all greenhouse gases from anthropogenic sources; most of this is due to deforestation and forest degradation. The Stern Review on the economics of climate change (Stern, 2007), furthermore, observed that “curbing deforesta...

the aim of this study was to assess the relative efficiency of the iranian forest management plans using the non-parametric method – data envelopment analysis (dea) as a well-known and robust technique for measuring the relative efficiency of organizations. the relative efficiency of forest management plans was calculated using the most frequency dea models such as global technical efficiency (...

The evolution of mod& forest resource management is focusing on ecologically-sensitive forest operations. This shift in management strategies is producing a new set of functional requirements for forest operations. Systems to implement ecosystem management prescriptionsmay need to be economically viable over a wider range of piece sizes, for example. Increasing demands for more efficient fiber ...

The Kholodninskoe pyrite-polymetallic deposit (Baikal-Patom plateau, Russia) was discovered in 1968, but the questions of its genesis still remain controversial. It is assumed that explosive activity volcanic apparatuses southern part Baikal-Muya zone as well underwater exhalations scattered spreading back-arc basin could have most likely influenced geochemical features amagmatic deposits Bodai...

Studies of the history and current status of forest resources in Northeast China have become important in discussions of sustainable forest management in the region. Prior to 1998, excessive logging and neglected cultivation led to a series of problems that left exploitable forest reserves in the region almost exhausted. A substantial decrease in the area of natural forests was accompanied by s...
