1. 21. The distribution of brown trout (Salmo trutta L.) in streams in southern Sweden

   Författare :Anders Eklöv; Biologiska institutionen; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; growth; density; intraspecific competition; predation; cover; interspecific interaction; fish assemblage; pollutant; recolonization; Ecology; Ekologi;

   Sammanfattning : This thesis examines the effect of water quality, habitat and species interactions on the occurrence and abundance of stream fishes in southern Sweden. I found that improvements in water quality between the 1960s and 1990s have led to recolonization of streams by brown trout (Salmo trutta L.), stone loach (Barbatula barbatula L. LÄS MER

3. 22. Investigations of thermophysical properties of slags with focus on slag-metal interface

   Författare :Luckman Muhmood; Seshadri Seetharaman; Nurni Neelakandan Viswanathan; Allan Cramb; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slags; density; diffusivity; sessile drop; interfacial velocity; interfacial viscosity; interfacial dilatational modulus; interfacial shear viscosity; Metallurgical process engineering; Metallurgisk processteknik;

   Sammanfattning : The objective of this research work was to develop a methodology for experimentally estimating the interfacial properties at slag-metal interfaces. From previous experiments carried out in the division, it was decided to use surface active elements like sulfur or oxygen to trace any motion at the interface. LÄS MER

4. 23. The Significance of Spaciousness: an investigation of spaciousness in the context of the residential yard

   Författare :Eva Kristensson; Institutionen för arkitektur och byggd miljö; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interior design; density; Spaciousness; densification; courtyard; residential yard; open space; Architecture; housing environment; Arkitektur; inredningsarkitektur;

   Sammanfattning : The new interest in density displayed by professional town planners and town-planning researchers is related to the present densification of the urban environment in many towns and cities. Research on densification is primarily concerned with the link between urban form and sustainable development. LÄS MER

5. 24. Spray-Dried Powders for Inhalation : Particle Formation and Formulation Concepts

   Författare :Jessica Elversson; Göran Alderborn; Anna Millqvist-Fureby; Lars Hovgaard; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Spray drying; Particle formation; Density; Protein formulation; Encapsulation; Coating; Competitive adsorption; Polymer; ESCA; AFM; FTIR; Galenisk farmaci; Pharmaceutics; Galenisk farmaci;

   Sammanfattning : Spray drying is a method with a high potential in the preparation of protein particles suitable for pulmonary delivery. However, surface induced denaturation of bio-molecules during atomization and subsequent drying can be substantial and it is therefore important to develop new formulation concept for concurrent encapsulation and stabilization of proteins during spray drying.

7. 25. Loss Minimisation in Dynamic Food Processes

   Författare :Marcus Henningsson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

   Sammanfattning : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. LÄS MER
