  1. 1. Detection of Contaminants in Water Using Surface Enhanced Raman Spectroscopy

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Freja Hansson; [2021]
    Nyckelord :Raman; Surface-enhanced Raman Spectroscopy; nanoparticles; contaminants; plasmonics;

    Sammanfattning : Due to deteriorating water quality and the world’s increasing demand for clean water, the need for cheap, easy and portable techniques to characterize and quantify pollutants in waters is urgent. Hence, surface-enhanced Raman spectroscopy (SERS) have gained considerable attention in this field. LÄS MER

  2. 2. LES modelling of spray combustion

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Arvid Åkerblom; [2021]

    Sammanfattning : Computational fluid dynamics is a powerful method for understanding the flow and combustion that occurs inside aircraft engines and will be a key tool in the transition from conventional fossil-based fuel to sustainable alternatives. Because conventional fuels have been more widely researched, an attempt at simulating the combustion of alternative fuels should be preceded by the development of a method that is capable of accurately simulating the combustion of a conventional fuel.

    Nyckelord :multi-task regression; QSAR; QSPR; deep learning; attention based models; transfer learning;

    Sammanfattning : With the recent advantages of machine learning in cheminformatics, the drug discovery process has been accelerated; providing a high impact in the field of medicine and public health. Molecular property and activity prediction are key elements in the early stages of drug discovery by helping prioritize the experiments and reduce the experimental work. LÄS MER

  4. 4. Extraction of miR-223 from human blood plasma and quantification using the two-tailed RT-qPCR and absolute quantification

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Lucija Marinkovic; [2021]
    Nyckelord :;

    Sammanfattning : Sepsis is a very dangerous and life-threatening disease that develops when the body’s reaction to infection causes damage to the body’s tissues and organs. It is difficult to diagnose it and it develops fast leading to a high mortality rate. LÄS MER

  5. 5. GAC filter Design Criteria for Wastewater Treatment for Removal of Organic Micropollutants – A Literature Review

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Bhargav Reddy Elavarthi; [2021]
    Nyckelord :micropollutants; activated carbon filtration; empty bed contact time EBCT ; pharmaceuticals; breakthrough curves; adsorption; PFOS; carbon use; water and environmental engineering; Technology and Engineering;

    Sammanfattning : Granular Activated Carbon (GAC) is nowadays suggested as a fourth (quaternary) treatment step at municipal wastewater treatment plants to remove certain chemicals and particularly organic micropollutants (OMPs). This work investigated the different factors that affect the performance of the GAC filter for the removal of micropollutants in a municipal wastewater treatment plant. LÄS MER
