  1. 1. Responses in river water quality during summers with extreme weather periods in Europe

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Felicia Claeson; [2021]
    Keywords : water quality; rivers; Europe; extremeweather periods; drought; heatwave; floods; dissolved oxygen; nitrate; chlorophyll-a; phosphate; Earth and Environmental Sciences;

    Abstract : Europe has experienced several climate extremes during the past decades. These extreme events have increased in number and intensity and are projected to further intensify. Previous studies show that heatwaves, drought, and flood can have an impact on water quality in several ways. READ MORE

  3. 2. Hydrological catchment analysis from characterisation of organic matter in stream water

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Hannes Berg Wiklund; [2020-02-05]
    Keywords : Organic matter; Time-of-flight mass spectrometry; aquatic chemistry; catchment hydrology;

    Abstract : Organic matter (OM) in aquatic systems is a complex field which have rapidly developed duringthe last decade due to the introduction of high resolution mass spectrometers. The compositionof OM in the aquatic environment is directly dependent on factors such as oxygen supply, pHand the flow rate in the local system. READ MORE

  4. 3. Ultrasonic Assisted Drying and its Effect on 3D Printability of Minced Beef and Other Foods

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

    Author : Viktor Lindström; [2020]
    Keywords : Drying; Convection drying; Ultrasound; Ultrasonic drying; 3D-Printing; 3D-Printability; Food; Meat; Beef; Food technology; Livsmedelsteknologi; Technology and Engineering;

    Abstract : The aim of this master thesis project was to investigate the impact on drying kinetics of ultrasound during air drying by a new ultrasonic transducer, on which a patent application has been filed by CSIRO. Convection drying using hot air is currently the conventional method of drying in the industry due to its simplicity and low cost. READ MORE

  5. 4. Development of a Near Infrared Spectroscopy Model for Prediction of Fibre Compounds in Alfalfa

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Christina Andersen; [2020]
    Keywords : alfalfa; lucerne; medicago sativa; green protein powder; NIR; near infrared spectroscopy; model development; matlab; PLS; partial least squares; PCA; principal component analysis; SNV; standard normal variate; fibre prediction; TDF; total dietary fibre; applied microbiology; teknisk mikrobiologi; Technology and Engineering;

    Abstract : Background: This project investigates if it is possible to develop a calibration model from near infrared (NIR) spectroscopic measurements, for determination of the amount and type of fibre fractions within protein powder produced from the legume alfalfa, without performing wet experiments. Alfalfa is also known as Medicago sativa and lucerne, but is in this project further referred to as alfalfa. READ MORE

  6. 5. Biophysical differences between COPD, CF and healthy airways mucus.

    University essay from Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Author : Vladislav Genevskiy; [2020]
    Keywords : CF; COPD; mucus; structure;

    Abstract : An improved understanding of the mucus biophysical alteration in chronic obstructive pulmonary disease (COPD) and cystic fibrosis (CF) patients is a milestone towards a more accurate and effective treatment of these common and highly debilitating conditions. Little is known about the variations in mucus structure between ill and healthy individuals. READ MORE
