  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.

    Abstract : Popular Abstract in Swedish På 70-talet upptäckte man att en grupp mikroorganismer, som man tidigare katalogiserat som bakterier, bildade en helt egen grupp. Dessa kallades ärkebakterier och fick senare namnet arkéer. READ MORE

  5. 5. Seawater pH as a Controlling Factor in Macroalgal Calcification and Photosynthesis

    University dissertation from Stockholm : Department of Botany, Stockholm University

    Author : Immaculate Sware Semesi; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Calcareous macroalgae; CO2; mussels; pH; seagrasses; tropical lagoons; NATURAL SCIENCES Biology Organism biology Plant physiology; NATURVETENSKAP Biologi Organismbiologi Växtfysiologi; Plant Physiology; växtfysiologi;

    Abstract : Biological calcification and photosynthesis are important processes with a great influence on both structure and function of oceanic ecosystems. The pH of the seawater has a strong influence on both these processes and therefore the impacts of different pH levels on calcareous macroalgae were investigated in laboratory and field experiments at Chwaka and Fumba Bays in Zanzibar, Tanzania.
