This paper explores various growth scenarios for Canada over the medium range to 2020 using LOWGROW, a dynamic simulation model. After describing LOWGROW, a scenario is presented that shows conditions under which the rate of unemployment in Canada could be reduced to historically low levels, poverty eliminated and greenhouse gas emissions reduced to comply with Canada's commitment under the Kyoto Protocol, without relying on economic growth. This is not to say that zero growth should itself become a policy objective. Rather that the dependence on and defence of economic growth should not be an obstacle to fulfilling more specific welfare enhancing objectives of full employment, eliminating poverty, and protecting the environment. The paper concludes with some policy implications for managing without growth followed by an annex which provides a technical description of LOWGROW.

The implementing company, Posiva Oy, owned by two nuclear power companies Teollisuuden Voima Oy (TVO) and Fortum, has marketed its concept ONKALO and the facilities as a "final solution" to the problem of high-level nuclear waste (HLW). A third Finnish nuclear power company, Fennovoima, is not included in the ONKALO project. Finland's political culture is based on structural corporatism and high trust of citizens in the state and its institutions, which partly explains the progress of Posiva's project and the relatively minor opposition to it. Public debates have focused more on new nuclear power plants (NPPs), which have been on the political agenda at the same time as the final disposal facility and its expansions. The

This new method employs a variety of indicators for a comprehensive and holistic analysis of sustainable development and green inclusive economy. The analysis is grounded in the assumption that economic development is required for social development, but that simultaneously development needs to be guarded or limited to protect the environment that underpins it. As all three dimensions of sustainable development are interlinked, a comprehensive analysis requires an analytical approach that is simultaneous. The analyses provide information on minimum levels of economic development that are needed to fulfil social sustainability criteria, in tandem with the maximum economic development that avoids breaching environmental sustainability criteria. If actual economic growth lies between these minima and maxima, we can interpret that development is more sustainable with respect to the relationships embodied by the selected social and environmental indicators. The main source of data is the database of the Sustainable Society Index (SSI) developed by the Sustainable Society Foundation (SSF). The indicators used by SSI have been chosen for the Sustainability Window analysis as they can be used to assess both 'weak' and 'strong' interpretations of sustainability. Weak sustainability is defined operationally as no increase in

The inhoMogeneity of peat as a fuel causes d i fficult i es i n the cont rol of peat powe r plants. When using standard in strumentat ion , the effect of changes in the quality of peat and disturbances in the feed can be obse r ved only at the steam p r oduced by the boiler. It is shown that the fue~ power correlates with the consumption of oxygen in the burning process. The correlation and a dynamic model of the plant forI!! a basis for two estimation schemes for the fuel power. These ideas also lead to compensat or y control of the fuel feed. Results from tests at Finn is h plants are included. The ideas presented are appl i cable also with other inhomogeneous fuels like coal , bar k , wood chips and wastes .

Building models for dry air and moist air were constructed in the Computational Fluid Dynamics, ANSYS Fluent 14.0 for numerical calculation of air flow rate and air temperature within the model. This study considered time-dependent turbulent flow and results when the system approaches steady state at 3 minutes. The hot air in the solar chimney was generated by a-constant heat flux of 60 W/m 2 in the chimney external wall. The dry-air models applied the Boussinesq's approximation. The species transport model was used to simulate the moisture content in the moist air. The simulation results showed that temperature of the moist air model was closer to the experiment than the dry air. The ventilation with dry air was lower than that with the moist air due to the reverse flow at the window. This research confirmed the optimum solar chimney ratio of 14: 1, similar to previous researches. In addition, the size of the opening between the building and the chimney highly affected the ventilation of the solar chimney. The best ventilation occurred in the chimney with inlet and outlet, as large as the width of the air space of the chimney.
