21. Latent Trait Models of Intrinsic, Extrinsic, and Quest Religious Orientations
Abstract : Allports and Ross (1967) Intrinsic and Extrinsic scales and Batsons and Schoenrades (1991b) Quest scale are re-analyzed from a unidimensional perspective by using the Rasch measurement model (RM). The RM of choice, Rating scale analysis, offers an alternative scaling procedure to Factor analysis. READ MORE

22. Model for activity coefficients and solubilities of Na2CO3 and Na2SO4 in high-temperature solutions
Abstract : Scaling of sodium sulfate and sodium carbonate double salts has long been recognized as a problem in the black liquor evaporation process. These salts are abundant in black liquor and often tend to precipitate on heat transfer areas, thereby significantly decreasing the heat transfer efficiency. READ MORE

23. Heat Transfer in Circulating Fluidized Bed Boilers
Abstract : Heat transfer to single particles in the transport zone of circulating fluidized beds and heat transfer to membrane tube walls have been investigated. The heat transfer coefficient to spheres in the transport zone of a circulating fluidized bed boiler has been measured with dark and light calorimeters. READ MORE

24. New Dimensions of Moving Bed Biofilm Carriers : Influence of biofilm thickness and control possibilities
Abstract : The moving bed biofilm reactor (MBBR) is a biological wastewater treatment process in which microorganisms grow as biofilms on suspended carriers. Conventionally, MBBRs are mainly designed and optimized based on the carrier surface area, neglecting the dynamic relationship between carrier design, reactor operation and biofilm characteristics, such as biofilm thickness and the composition of the microbial community.

25. Moisture Conditions and Frost Resistance of Concrete in Hydraulic Structures
Abstract : Owing to the winter conditions in Sweden, the effects of frost action may have a considerable impact on the deterioration of concrete. Both superficial and internal damage, which are suspected to have been caused by frost action, have been found in concrete in hydraulic structures. READ MORE
