  1. 1. Hydrogel-based pH-sensors Development and characterisation of optical and electrical pH sensors based on stimuli-responsive hydrogels

    University dissertation from Sundsvall : Mid Sweden University

    Author : Krister Hammarling; Mittuniversitetet.; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogel; fiber optics; printed electronics; pH; sensor;

    Abstract : The ability to measure the chemical parameter pH is of high importance in many areas. With new government regulations and evolving markets, there is a strong motivation for improving such measurements and conducting research on new types of pH sensors and sensor materials. READ MORE

  2. 2. Complex disease genetics Utilising targeted sequencing and homogeneous ancestry

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Argyri Mathioudaki; Uppsala universitet.; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ankylosing spondylitis; breast cancer; targeted sequencing; Sweden; genetics; population stratification.; Molekylär genetik; Molecular Genetics;

    Abstract : The complex disease investigations presented in this thesis aimed to provide new information regarding underlying genetics by using targeted sequencing and ethnically homogeneous cohorts. This work moved past current methodologies and addressed data stratification issues, that might have been hindering new findings.

  3. 3. Soil-living archaea: Influence of pH, carbon and nitrogen on their abundance and activity

    University dissertation from Department of Biology, Lund University

    Author : Anna Sterngren; Lund University.; Lunds universitet.; [2014]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Archaea; ammonia-oxidizing archaea; soil; AOA; AOB; root exudates; gross nitrification; qPCR; pH; carbon cycle; nitrogen cycle;

    Abstract : During the last decade it has been discovered that around 2% of the soil-living prokaryotes belong to the domain Archaea. In many soils the most abundant archaeal group is the ammonia-oxidizing archaea (AOA) that, in addition to ammonia-oxidizing bacteria (AOB), preform the first and rate-limiting step in the nitrification process.

  4. 4. Nanofiltration at elevated temperatures: Influence of the combined effects of temperature, salts, pH and cleaning

    University dissertation from Faculty of Engineering, LTH at Lund University

    Author : Mattias Nilsson; Lund University.; Lunds universitet.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elevated temperatures; Electroviscous friction; Energy; pH; Economics; Nanofiltration; Pre-treatment; Salt; Swelling; Membrane performance; Cleaning; Temperature;

    Abstract : The influence of temperature, salts, pH, and various pre-treatments and cleaning on the nanofiltration (NF) performance of thin-film polyamide (PA) composite membranes has been investigated. The change in membrane performance was correlated to membrane swelling or/and electroviscous friction. READ MORE

  5. 5. The Oxygen Evolving cycle in Photosystem II studied with EPR Spectroscopy at different pH and Temperature

    University dissertation from Biochemistry Department Lund University P.O. Box 124 SE-22100 Lund Sweden

    Author : Susan F Morvaridi; Lund University.; Lunds universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; Naturvetenskap; Temperature; Natural science; pH; EPR; S cycle; Photosystem II;

    Abstract : PSII catalyses the light-induced water splitting process which leads to electron transfer through the thylakoid membrane and formation of energy rich molecules. Several redox components including a Mn4Ca, an amino acid residueYZ, two special Chl molecules P680, two Pheo and two quinone molecules participate in this process. READ MORE
