   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Filtering; Ash Recycling; Change Detection; System Identification; Real-Time Control; Robust Control; Process Design; Control System Design; Carbon In Fly Ash CIFA monitoring; PID-Control; Agglomeration Techniques; Moisture Control; Dehydration Techniques.; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : In Sweden, extensive research is conducted to find alternative sources of energy that should partly replace the electric power production from nuclear power. With the ambition to create a sustainable system for producing energy, the use of renewable energy is expected to grow further and biofuels are expected to account for a significant part of this increase.

4. 2. The Survey of Ash Agglomeration Phenomena in a Commercial Circulating Fluidised Bed (CFB)

   Author : Ann Charlotte Tranvik; Mehri Sanati; Britt-Marie Steenari; Växjö universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CFB; combustion; biomass; agglomeration; ash; silicate; potassium; bed material; layer; deposition; Thermal energy engineering; Termisk energiteknik;

   Abstract : Renewable energy sources will act an important roll in the development of sustainability in the future in order to protect environment and ecological cycle.Amongst the Kyoto protocol conclusions there is an agreements for the EU a reduction of 8 % of greenhouse gas emissions (corresponding of around 6 million tonnes of CO2 equivalents ) between 2008-2012 (compared to 1990 level).

5. 3. Essays on Industrial Development and Political Economy of Africa

   Author : Eyerusalem G. Siba; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Agglomeration economies; African manufacturing; Credit constraints; Darfur; Ethiopia; Ethnic cleansing; Growth; Informal sector; New firms; Poverty trap; Prices; Productivity; Resource struggle; Returns to capital; Survival; Skills.;

   Abstract : Paper 1: Returns to Capital and Informality. We study the pattern of returns to capital in the formal and informal manufacturing sectors in Ethiopia. We use a rich panel dataset of manufacturing firms in the formal sector for the period 1996-2006 and two rounds of repeated cross-sectional data of the urban informal sector firms. READ MORE

6. 4. Layer Formation on Bed Particles during Fluidized Bed Combustion and Gasification of Woody Biomass

   Author : Hanbing He; Marcus Öhman; Kent Davidsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; layer formation; bed particle; woody biomass; quartz; K-feldspar; olivine; bed agglomeration; deposition; fluidized bed; combustion; gasification; Energiteknik; Energy Engineering;

   Abstract : Although more than a hundred papers dealing with the agglomeration problem in combustion and gasification of biomass can be found in the literature, very few studies focusing on the bed particle layer formation process in fluidized bed combustion (FBC) and fluidized bed gasification (FBG) can be found. With increased knowledge of the bed particle layer formation process — i. READ MORE

7. 5. Identification and Variation of some Functionality Related Characteristics of Pharmaceutically Relevant Solid Materials and their Effect on Product Performance

   Author : Frauke Fichtner; Göran Alderborn; Åke Rasmuson; Peter Kleinebudde; Uppsala universitet; []
   Keywords : Pharmaceutics; Particle size distribution; Degree of agglomeration; Amorphous lactose; Matrix agglomerates; Drug release; Compactability; Tablet tensile strength; Particle fracture strength; Surfactant; Compression; Galenisk farmaci;

   Abstract : The aim of this thesis was to identify some functionality related characteristics of pharmaceutically relevant solid materials and to study the effect of their variation on processing behaviour and product performance. For this purpose, particles with different characteristics were prepared under a variety of conditions by crystal agglomeration, wet granulation and spray drying. READ MORE
