2. 1. Carbon Recovery in A Dual Fluidized Bed Gasifier

   Author : Sébastien Pissot; Chalmers University of Technology; []
   Keywords : TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

   Abstract : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. READ MORE

4. 2. Investigation of nitrogen recovery from concentrated wastewater

   Author : Aubrey Shenk; Monica Odlare; Eva Thorin; Sebastian Schwede; Ershad Ullah Khan; Mälardalens högskola; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; nitrogen; ammonium; recovery; circular economy; wastewater; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : Nitrogen recovery from wastewater treatment for fertilizers is a research topic that exists at the intersection of multiple topics important to the future of sustainable society. First, nitrogen recovery from wastewater implies a departure from the current methods of nitrogen mitigation, which involve nitrogen removal by conversion of various aqueous species to inert nitrogen gas.

5. 3. A passage to wastewater nutrient recovery units : Microalgal-Bacterial bioreactors

   Author : Anbarasan Anbalagan; Jesus Zambrano; Sebastian Schwede; Carl-Fredrik Lindberg; Emma Nehrenheim; Francisco Gabriel Acién Fernández; Mälardalens högskola; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Microalgae; Bacteria; Carbon; Nitrogen; Light; Energy- and Environmental Engineering; energi- och miljöteknik;

   Abstract : In recent years, the microalgal–bacterial process has been considered to be a very attractive engineering solution for wastewater treatment. However, it has not been widely studied in the context of conventional wastewater treatment design under Swedish conditions. READ MORE

6. 4. Low temperature acclimation in plants : alterations in photosynthetic carbon metabolism

   Author : Maria Lundmark; Vaughan Hurry; Charles Guy; Umeå universitet; []
   Keywords : Plant physiology; cold acclimation; carbon metabolism; photosynthesis; respiration; Växtfysiologi; Physiological Botany; fysiologisk botanik;

   Abstract : Although low temperature plays an important role in determining agricultural yield, little is known about the effect on the underlying biochemical and physiological processes that influence plant growth. Photosynthesis and respiration are central to plant growth and both processes are heavily affected by temperature. READ MORE

7. 5. Modification of flavonoid content and photosynthesis by ultraviolet-B radiation. Atrazine-tolerant and -sensitive ultivars of Brassica napus

   Author : Louise Olsson; Biologiska institutionen; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; recovery; quercetin; photosynthesis; photoinhibition; photoacoustics; leaf anatomy; kaempferol; flavonoid; D1 protein; fluorescence; cold stress; carbon dioxide; atrazine tolerance; Brassica napus; UV-B; Physiological biophysics; Växtfysiologi;

   Abstract : Levels of ultraviolet-B (UV-B, 280-320 nm) radiation reaching the Earth´s surface increase due to stratospheric ozone depletion. In this thesis the effect of enhanced UV-B radiation was studied on the atrazine-tolerant mutant Stallion, susceptible to photoinhibition, and the atrazine-sensitive cultivar Paroll of Brassica napus (oilseed rape).
