  1. 1. God grundvattenkvalitet?

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Elvira Källberg; [2019]
    Keywords : Drinking water; pollution Bergaån; iron; manganese PFAS and pesticides; Earth and Environmental Sciences;

    Abstract : Clean drinking water is a crucial part of a healthy society. During the last decades, a lot of emissions from different sources have put the drinking water sources that are used today at risk of pollution. READ MORE

  2. 2. Theoretical study of anisotropic effects in crystal growth on the example of concrete and calcium oxalate monohydrate

    University essay from Lunds universitet/Kemiska institutionen

    Author : Vilhelm Ekberg; [2019]
    Keywords : anisotropic crystal growth; COM; C-S-H; PM6; ReaxFF$_{ textrm{SiO}}$; organizing molecular matter; nanochemistry; nanokemi; Chemistry;

    Abstract : While many crystals, both natural and artificial, grow isotropically, there are examples of crystals growing anisotropically. The aim of this theoretical study was to confirm the growth modes displayed by three different crystals, representing 3D, 2D and 1D structures. READ MORE

  3. 3. Energy & redox fluxes in Lactobacillus reuteri DSM 17938 on different sugars

    University essay from Lunds universitet/Teknisk mikrobiologi; Lunds universitet/Bioteknik

    Author : Katarzyna Bengtsson; [2019]
    Keywords : Energy; redox fluxes; Lactobacillus reuteri DSM 17938; different sugars; applied microbiology; teknisk mikrobiologi; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Under anaerobic condition the specific growth rate of Lactobacillus reuteri DSM 17938 on different sugars, was analyzed using spectrophotometry. Electron acceptor (fructose) supported cells to cope with poor energy recovery by re-oxidising the NADH, thus enabling ATP formation thru acetate production, while fermenting glucose via the phosphoketolase pathway (PKP) and simultaneously operating via Embden-Meyerhof pathway (EMP).

  4. 4. The content, chemical state and accumulation of vanadium in a drill core of Alum shale from Kinnekulle

    University essay from Lunds universitet/Kemiska institutionen

    Author : Niklas Gunnarsson; [2019]
    Keywords : Alum Shale Formation; Alum shale; Kinnekulle; Vanadium; Inorganic chemistry; Oorganisk kemi; Chemistry;

    Abstract : Exploitation of alum shale is a controversial subject in Sweden due to the history of pollution of the environment and groundwater, from past mining industries. The extraction of vanadium from alum shale is no different. Nevertheless the metal is a valuable resource used in tools, building, industries and aerospace materials. READ MORE

  5. 5. Simulation of Colorless Distributed Combustion

    University essay from Lunds universitet/Institutionen för Energivetenskaper

    Author : Hampus Olsson; [2019]
    Keywords : Computational Fluid Dynamics; Combustion; Gas Turbine; Emission reduction; Flameless Combustion; Colorless Distributed Combustion; Technology and Engineering;

    Abstract : Colorless distributed combustion (CDC) is a promising novel technology to reduce emissions of carbon monoxide and nitrogen oxides in gas turbine combustors. CDC features a different flame regime than conventional gas turbine combustors, associated with a distributed reaction zone and low and uniform temperatures due to dilution of combustion air with exhaust gases.
