2. 1. Biogas Production from Citrus Wastes and Chicken Feather : Pretreatment and Co-digestion

   Author : Gergely Forgács; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; anaerobic digestion; pretreatments; co-digestion; economic analyses; citrus wastes; feather; Energi; material; Resursåtervinning; Resource Recovery;

   Abstract : Anaerobic digestion is a sustainable and economically feasible waste management technology, which lowers the emission of greenhouse gases (GHGs), decreases the soil and water pollution, and reduces the dependence on fossil fuels. The present thesis investigates the anaerobic digestion of waste from food-processing industries, including citrus wastes (CWs) from juice processing and chicken feather from poultry slaughterhouses.

4. 2. Citrus Waste Biorefinery: Process Development, Simulation and Economic Analysis

   Author : Mohammad Pour Bafrani; Mohammad Pourbafrani; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process simulation; encapsulated yeast; Citrus wastes; economic analysis; computational fluid dynamic simulation; pectin; limonene; methane; ethanol;

   Abstract : The production of ethanol and other sustainable products including methane, limonene and pectin from citrus wastes (CWs) was studied in the present thesis. In the first part of the work, the CWs were hydrolyzed using enzymes – pectinase, cellulase and β-glucosidase – and the hydrolyzate was fermented using encapsulated yeasts in the presence of the inhibitor compound ‘limonene’.

5. 3. Functional properties of galectin-3. Beyond the sugar binding

   Author : Adriana Lepur; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; galectin-3; galectin-1; M1 macrophage; M2 macrophage; self-association; fluorescence anisotropy; citrus pectin; galactomannane;

   Abstract : Contemporary diseases like diabetes, asthma, atherosclerosis etc. are marked by chronic inflammation, often supported by the activity of different macrophages. Proteins from galectin family were found to contribute to disease pathophysiology. Therefore, there is an intensive interest in understanding different galectin functions. READ MORE

6. 4. Soil Degradation of Raised-beds on Orchards in the Mekong Delta Field and Laboratory Methods

   Author : Quang Pham Van; Per-Erik Jansson; Khoa Le Van; Ingmar Messing; KTH; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; citrus orchards; nutrient; soil fertility; soil strength; soil degradation; alluvial soil; Mekong delta;

   Abstract : Soil degradation is a complex process which may occur anywhere and at any time. It directly affects the physical, chemical and biological processes within the soil profile. Soil degradation can either be as a result of natural hazards or due to manmade actions, such as mismanagement on cropping patterns, soil preparation and cultivation practices. READ MORE

7. 5. Methane and Volatile Fatty Acids Production from Toxic Substrate

   Author : - Lukitawesa; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; toxic substrate; methane; volatile fatty acid; anaerobic digestion; membrane bioreactor; factor; tubular membrane; two-stage digestion; Resource Recovery; Resursåtervinning;

   Abstract : Challenges caused by climate change and global warming have created a demand for improvements in resource recovery and the promotion of a circular economy. Waste management is one such challenge for which more recycling options are required for producing materials and energy sources from wastes. READ MORE
