  1. 1. Using biological conversion to increase the value of short-chain fatty acids by mixed cultures

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Elisabeth Beach; [2023]
    Keywords : Ethanol; Mixed culture; Volatile fatty acids; Anaerobic digestion;

    Abstract : The development of anaerobic digestion processes has gained recognition for its potential for producing volatile fatty acids alongside bio-alcohols. In addition, the fermentation process and the products produced from biological fermentation have the possibility to overcome the abundance of organic waste in our society, which is potentially immensely rich in untapped valuable potential products.

  3. 2. High-loaded thermophilic anaerobic digestion of mixed sewage sludge : A pilot study

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Santiago Elejalde Bolaños; [2022]
    Keywords : thermophilic anaerobic digestion; volatile fatty acids; mixed sludge; organic loading rate; alkalinity; wastewater treatment plant; termofil rötning; flyktiga fettsyror; blandslam; organisk belastning; alkalinitet; avloppsreningsverk;

    Abstract : Municipal wastewater treatment plants (WWTP) are important infrastructural components in a society and also important for sustainability. In a WWTP the most common treatment configuration is mechanical, biological, and chemical treatment of the wastewater. READ MORE

  4. 3. Automating Water Orientation in Neutron Crystallography using Convolutional Neural Networks

    University essay from Lunds universitet/Matematik LTH

    Author : Simon Bakran; [2022]
    Keywords : Technology and Engineering;

    Abstract : One important aspect of determining the functionality of proteins is to find the direction of the dipole moment of surrounding water molecules. This is equivalent to finding the position of the hydrogen in water, however with the current atomistic model building tools this is a tedious and time-consuming task. READ MORE

  5. 4. Klimatpåverkan och energianvändning vid tillämpning av bio-CCS och bio-CCU från biogasanläggningar

    University essay from SLU/Dept. of Energy and Technology

    Author : Emelie Wallman; [2022]
    Keywords : livscykelanalys; koldioxid; biometan; power to gas; biologisk metanisering; katalytisk metanisering; elektrolys;

    Abstract : To mitigate the human-induced climate change, Sweden has adopted a climate policy framework that states a net-zero emissions of greenhouse gases by the year of 2045 and thereafter negative emissions. To achieve this goal extensive emission mitigation alongside supplementary measures are required. READ MORE

  6. 5. Ancient plant cuticle chemistry: preservation and characterization of organic matter as biomarker of past UV-B radiation

    University essay from KTH/Kemi

    Author : Larissa Lopes Cavalcante; [2021]
    Keywords : UACs; fossil cuticle; p-coumaric acid; ferulic acid; UV-B proxy; micro-FTIR; confocal Raman microscope; UAF; fossil kutikula; p-kumarinsyra; ferulinsyra; UV-B-proxy; mikro-FTIR; konfokalt Raman-mikroskop;

    Abstract : Biologiska processer hos olika organismer påverkas av ultraviolett-B-strålning (UV-B). Kunskapen om förändringar i UV-B-flödet som nått planetens yta under det geologiska tidsspann sedan flercelligt liv uppstod är dock begränsad. READ MORE
