  4. 3. Application of machine learning for the clustering of wheat transcription factor proteins into families and sub-families

    University essay from Stockholms universitet/Institutionen för data- och systemvetenskap

    Author : Haleemath Sameena Sameer; [2022]
    Keywords : Global food security; Machine learning; Transcription factor proteins; K Mean WRKY; Clustering; Salinity;

    Abstract : Wheat plays an important role in ensuring the global food security. Salinity of soil and water poses a major threat to its production and it affects both growth and development of wheat in a negative way. Wheat plants uses certain molecular mechanisms to adapt themselves under the salt stress. READ MORE

  5. 4. X-ray-induced intermolecular reactions in mixed clusters

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Astrid Bergman; [2022]
    Keywords : molecular cluster; biophysics; X-ray;

    Abstract : The aim of this project was to study what mixed cluster fragments were formed in the interaction between radiation and H2O-CO2 clusters formed by adiabatic expansion, both experimentally and using simulations. The experiment was done using a mass spectrometer at the MAX IV synchrotron facility and by studying the time-of-flight of the ionic fragments. READ MORE

  6. 5. Quantum chemical studies of the reactivity of gold nanoparticles towards molecular radicals

    University essay from KTH/Kemi

    Author : Sofia Larsson; [2022]
    Keywords : gold nanoparticles; surface electrostatic potential; average local ionization energy; electron attachment energy; free molecular radicals; guldnanopartiklar; elektrostatisk ytpotential; genomsnittlig lokal joniseringsenergi; fria molekylära radikaler;
