1. 16. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

   Författare :Eva Ståhl Wernersson; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

   Sammanfattning : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. LÄS MER

3. 17. Food Cultures in Sápmi : An interdisciplinary approach to the study of the heterogeneous cultural landscape of northern Fennoscandia AD 600–1900

   Författare :Markus Fjellström; Gunilla Eriksson; Kerstin Lidén; Lars Liedgren; Marianne Skandfer; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; Food Culture; Diet; Mobility; Iron Age; Middle Ages; Sápmi; Sámi Archaeology; Reindeer Domestication; Stable Isotope Analysis; Elemental Analysis; Repatriation; Reburial; arkeologi med inriktning mot laborativ arkeologi; Scientific Archaeology;

   Sammanfattning : The aim of this thesis is to highlight the heterogeneous cultural landscape in Sápmi through the study of food. By studying food and the choices of specific foodstuffs in Sápmi AD 600–1900, a greater understanding can be gained on the history of this area during the period. LÄS MER

4. 18. Effects of Pulsed Electric Fields on Plant Tissue

   Författare :Yongyut Chalermchat; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technological sciences; Electropermeabilization; Pulsed electric fields; Plant Tissue; Teknik;

   Sammanfattning : The interaction between biological cells and external electric fields has been of interest by scientists for several decades. Exposure of the cells to electric fields leads to various kinds of biophysical and biochemical responses. These responses can be used to characterize cell properties and/or to manipulate cell characteristics. LÄS MER

5. 19. Designing Community Economies : Exploring Alternatives for Infrastructuring Food Waste Activism

   Författare :Katie Berns; Chiara Rossitto; Jakob Tholander; Danielle Wilde; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Digital Civics; Food-Sharing; Activism; Food Waste; Community Economies; PAR; informationssamhället; Information Society;

   Sammanfattning : By drawing on past CSCW and SHCI scholarship engaged with how technology can support the collaborative work of organising activism and empowering people to respond to diverse sustainability challenges– my research contributes to the emerging field of digital civics by introducing the human geography concept ‘community economies’ as a new way to frame and determine the scope of the design of digital technologies for infrastructuring food waste activism. Using a combination of ethnographic research and participatory action research (PAR), the empirical data were collected through two long-term collaborations with food-sharing communities in Denmark and Sweden and through a collaboration with researchers on a related project that focused on a food-sharing community in Germany.

7. 20. Technological Aspects of Preparing Porridges Made from Local Crops in Mozambique

   Författare :Irene Carvalho; Livsmedelsteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Child malnutrition; consistency; complementary porridge; developing countries; energy density; carotenoids;

   Sammanfattning : Child malnutrition is one of the major health problems in many developing countries and involves many sectors such as health, agriculture and research. Malnutrition in infants usually develops during the introduction of complementary foods, due to a deficit of nutrients, low energy density and the poor bioavailability of vitamins and minerals leading, in turn, to an increase in the risk of disease and infant mortality.
