  1. 1. Lakes are browner in the south than in the north of Sweden despite similar levels of dissolved iron

    University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Author : Fredrik Lindgren; [2019]
    Keywords : Brownification; DOC; dissolved iron; humic lakes; sulphur deposition; absorbance; climate change;

    Abstract : During recent decades many lakes have become browner in the northern hemisphere and more specific in Sweden. This process is called brownification. Brownification of lakes makes it more difficult to clean water to drinking water and may have negative ecological effects on biota. READ MORE

  2. 2. Acrylamide in Ready-to-Eat Potato Products

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Lovisa Norén; [2019]
    Keywords : food engineering; livsmedelsteknik; Technology and Engineering; Agriculture and Food Sciences;

    Abstract : The formation of the suspected carcinogenic compound acrylamide has become a noticed problem in the heat processing of several types of carbohydrate rich food items. The European Union is currently working to mitigate these levels, where one strategy is to implement a new regulation with benchmark levels for acrylamide in different products. READ MORE

  3. 3. Investigating Optical-Field-Induced Currents in GaN using Ultrafast Lasers

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Abstract : This study saw the development of an experimental setup capable of generating and measuring optical-field-induced currents in a variety of nanodevices fabricated specifically for this project. Each device design features two metallic contacts, closely separated by about 5 micrometers, deposited onto a semiconductor or insulator substrate. READ MORE

  4. 4. Exploring Deep Eutectic Solvent Pretreatment and Laccase Biobleaching on Oat Hulls in Efforts to Overcome Recalcitrance

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Juanita Francis; [2019]
    Keywords : Biotechnology; Bioteknik; Technology and Engineering;

    Abstract : Oat production produces an abundant side stream product called oat hulls, formally regarded as a waste product. These oat hulls are nutritionally packed, containing insoluble dietary fibres. The solubilization and subsequent enzymatic hydrolysis of insoluble fibres, i.e. READ MORE

  5. 5. Interactive Visualization of Solar Energy Data

    University essay from Uppsala universitet/Institutionen för informationsteknologi; Uppsala universitet/Institutionen för informationsteknologi; Uppsala universitet/Institutionen för informationsteknologi

    Author : Isak Borg; August Dixelius; David Östlund; [2019]
    Keywords : ;

    Abstract : Sweden has one of the lowest solar energy productions in Europe even though the weather conditions are comparable to Europe’s largest solar energy producer. Although the majority of the Swedish population is in favour of spending more money on services that can limit climate change, the growth of installed solar cells is slower than that of other countries with similar climate in Europe.
