The wood pellet business in Russia with the role of North-West Russian regions: Present trends and future challenges
(Elsevier Ltd, 2015)The Russian wood pellet business has expanded rapidly in the last decade. The first Russian pellet production plant was built in 2003 and within ten years, Russia has become an important exporter of pellets, mainly to the ... -
Logistical, economic, environmental and regulatory conditions for future wood pellet transportation by sea to Europe: The case of Northwest Russian seaports
(Elsevier Ltd, 2016)International trade in biomass for energy is growing and wood pellets have become a very successful internationally traded bioenergy-based commodity. Russian wood pellets have captured an important share of European markets. ... -
Five years left – How are the EU member states contributing to the 20% target for EU's renewable energy consumption; the role of woody biomass
(Elsevier Ltd, 2016)The European Union has set ambitious targets of raising the share of EU energy consumption produced from renewable resources from 20% by 2020 to 27% by 2030. The aim of this paper is to assess the role of woody biomass in ... -
Biomass for industrial applications: The role of torrefaction
(Elsevier Ltd, 2017)Torrefied biomass has considerable potential as a biomass fuel to replace coal in energy and process heat production. The aim of this paper is to evaluate the potential of torrefied biomass in different industries, both ... -
A survey analysis of the wood pellet industry in Finland: Future perspectives
(Elsevier Ltd, 2017)Finland has the greatest forest cover of European countries and thus considerable raw material potential for wood pellet market development. Wood pellet production and consumption volumes in the country have increased ... -
Data demonstrating the Finnish wood pellet industry and future perspectives
(Elsevier Ltd, 2017)This article contains data related to the research article entitled “A survey analysis of the wood pellet industry in Finland: Future perspectives" (S. Proskurina, E. Alakangas, J. Heinimö, M. Mikkilä, E. Vakkilainen, 2016) ... -
Fuzzy Logic and Zadeh Algebra
(Scientific Research, 2017)In this work we create a connection between AFS (Axiomatic Fuzzy Sets) fuzzy logic systems and Zadeh algebra. Beginning with simple concepts we construct fuzzy logic concepts. Simple concepts can be in- terpreted semantically. ... -
Global biomass trade for energy – Part 1: Statistical and methodological considerations
(Society of Chemical Industry and John Wiley & Sons, Ltd, 2017)Many countries have limited, low-cost biomass resources to satisfy their own demand for bioenergy. International trade of biomass in various solid and liquid forms is consequently increasing. The aim of this study is to ... -
Global biomass trade for energy— Part 2: Production and trade streams of wood pellets, liquid biofuels, charcoal, industrial roundwood and emerging energy biomass
(Society of Chemical Industry and John Wiley & Sons, Ltd, 2018)Many countries have limited low-cost biomass resources to satisfy their own demand for bioenergy; consequently, international trade in biomass in various liquid and solid forms is increasing. The aim of this study is to ... -
Effect of loading type on the fatigue strength of asymmetric and symmetric transverse non-load carrying attachments
(Wiley, 2016)This study considers the effect of bending loading and the symmetry of joints on the fatigue strength of transverse non-load carrying attachments. Conventionally, the fatigue strength of a welded joint has been determined ... -
Fatigue Performance of GMA-Brazed Non-Load Carrying Joints Made of Ultra-High Strength Steel
(Springer International Publishing AG, 2018)With the aim of maximizing energy efficiency, the use of low-alloyed ultra-high strength steels (UHSS) has greatly increased in vehicles and other transport applications in recent decades. Using UHSS, equivalent ultimate ... -
Performance and flow fields of a supersonic axial turbine at off-design conditions
(Institution of Mechanical Engineers, 2013)The increasing demand of energy efficiency and the utilisation of small-scale energy sources require efficient, small and versatile turbines. Supersonic turbines have a high power density and therefore small size and fewer ... -
Importance of the vane exit mach number on the axial clearance-related losses
(Sage Journals, 2016)More efficient and physically smaller axial turbine designs are promoted to lower emissions and increase revenue. The physical size and the weight of the axial turbine can be minimised by adjusting the distance between ... -
Influence of the axial turbine design parameters on the stator–rotor axial clearance losses
(Sage Journals, 2014)The drive towards lower emissions in aerospace engines promotes more efficient and physically smaller engines. One way to decrease the size of the axial turbine is to minimize the distance between successive stator and ... -
Experimental study of centrifugal compressor tip clearance and vaneless diffuser flow fields
(Sage Journals, 2013)Three vaneless diffuser designs, varying in diffuser width, for centrifugal compressor were studied experimentally. Along with the diffuser width, the tip clearance was altered. The compressor overall performance and ... -
Effect of Vaneless Diffuser Width on the Overall Performance of a Centrifugal Compressor
(Sage Journals, 2011)Three vaneless diffuser designs, varying in diffuser width, for centrifugal compressor were studied experimentally. Along with the diffuser width, the tip clearance was altered. The compressor overall performance and ... -
Untangling the value-creation and value-appropriation elements of coopetition strategy: A longitudinal analysis on the firm and relational levels
(Elsevier, 2014)Collaboration among competing firms (i.e., coopetition) highlights the co-existence of value creation and appropriation due to the simultaneity of competition and collaboration in the relationship. As a consequence, there ... -
Greenhouse gas reduction potential by producing electricity from biogas engine wate heat using organic Rankine cycle
