Thermochemical biomass conversion systems have the potential to produce heat, power, fuels and other products from forest biomass at distributed scales that meet the needs of some forest industry facilities. However, many of these systems have not been deployed in this sector and the products they produce from forest biomass have not been adequately described or characterized with regards to ch...
--The Russian forest sector is currently under pressure of an economic crisis. Average annual production of the roundwood has decreased about 3 times since 1989. Limited domestic demand for forest products restricts production growth and the development of the technology in forest industries. At the same time forest resources are not fully utilized. However, this situation may change in the fut...
Bioproducts are nonfeed or food industrial goods composed to a significant degree from biological products, renewable domestic agricultural materials, or forestry materials. Hydraulic fluids, lubricants, biopharmaceuticals, chemicals, and building materials all fall within the product range of bioproducts. There are a wide variety of feedstocks that can be used to make bioproducts, including gr...

As a consequence of the large top quark Yukawa coupling, supersymmetric unified theories with soft supersymmetry breaking terms generated at the Planck scale predict lepton flavour and CP violating processes with significant rates. The flavour violating parameters of the low energy theory are derived in both SU(5) and SO(10) theories, and are used to calculate the rate for μ → eγ. The sensitivi...
Forest products value chains (FPVC) are complex networks of units incorporating different goals and beliefs. These units need to work together to generate the different elements of value. To study these value chains, a common representation and understanding of the different components of a value chain must be obtained. This will permit the evaluation of forest and industry strategies, supply c...
The forest products industry is a major component of Mississippi’s economic base. The need for a county-level forest inventory and the availability of decision support tools for locating forest product mills are of primary importance in attracting and sustaining the industry. The objective of this paper is to describe the pilot study, currently under development, for an integrated decision supp...
We evaluated the conservation attitudes of the local villagers living adjacent to the Kalakad-Mundanthurai Tiger Reserve in southern India 6 years after implementation of a World Bank funded eco-development project. We assessed attitudes towards three facets of conservation: the tiger, an emblematic species signifying India's commitment to wildlife conservation; the forest, a principle source o...
Introduction Community Based Forestry (CBF) implies commitment to the long term ecological, economic and social well being of forest dependent communities. CBF, or community scale sustainable forestry, constitutes a departure from industrial forestry due to this commitment to the preservation of the ecological integrity of the forest ecosystem in perpetuity and to the maintenance or improvement...
The forests of North America provide a variety of benefits including water, recreation, wildlife habitat, timber, and other forest products. However, they continue to face many biotic and abiotic stressors including fires, native and invasive pests, fragmentation, and air pollution. Forest health specialists have been monitoring the health of forests for many years. This paper highlights some o...
