3. 2. PV water pumping systems for agricultural applications

   Författare :Pietro Elia Campana; Jinyue Yan; Hailong Li; Lawrence Kazmerski; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Grassland and farmland degradation is considered as one of the worst environmental and economic threats for China. The degradation process negatively affects food and water security, economy, society and climate changes. LÄS MER

4. 3. PV water pumping systems for grassland and farmland conservation

   Författare :Pietro Elia Campana; Jinyue Yan; Bengt Perers; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : Grassland degradation is considered as one of the worst environmental and economic problems in China because of the negative impacts on water and food security. The application of the photovoltaic water pumping (PVWP) technology for irrigation is an innovative and sustainable solution to curb the progress of grassland desertification and to promote the conservation of farmland in remote areas.

5. 4. An evaluation of solar powered irrigation as carbon offset projects

   Författare :Alexander Olsson; Jinyue Yan; Björn Frostell; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; carbon offset; carbon sequestration; clean development mechanism; climate change adaptation; desertification; solar power water pumping; Chemical Engineering; Kemiteknik;

   Sammanfattning : Carbon offsets have been developed as one tool to incentivise investments by developed nations in climate change mitigation activities in developing countries. The carbon offsets can be used towards the countries’ own mitigation targets but are also meant to benefit developing countries by providing a pathway to clean development. LÄS MER

7. 5. Prevention of hemolysis as a novel strategy to limit hemoglobin-mediated lipid oxidation in fish - towards a more sustainable use of fish raw materials

   Författare :Semhar Ghirmai; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hemoglobin; herring Clupea harengus ; fish; rainbow trout Oncorhynchus mykiss ; erythrocyte; hemolysis; side-stream; antioxidant; lipid oxidation; blood plasma;

   Sammanfattning : Hemoglobin (Hb) has been recognized as a main pro-oxidant in fish, causing fast and intense lipid oxidation. This thesis explores the hypothesis that maintaining red blood cells (RBCs) intact for an extended time during fish processing could delay Hb-mediated lipid oxidation. LÄS MER
