  2. 1. Periodized Thermal Greens Functions and Applications

    Author : Andro Sabashvili; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; Greens function; graphene; DMFT; RPA; GW;

    Abstract : This work describes a new formalism for Fermionic thermal Greens functions that are discretized in imaginary time. The discretization makes the thermal Greens function periodic in imaginary (Matsubara) frequency space and requires a generalisation of the Dyson equation and Luttinger-Ward-Baym-Kadanoff functional.

  4. 2. Necked-in Superdeformed Nuclei

    Author : Lars-Ove Jönsson; Matematisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; thermodynamics; statistical physics; gravitation; cranked Nilsson-Strutinsky; superdeformation; necked-in shapes; RPA; giant dipole resonance; finite-range liquid drop model; Mathematical and general theoretical physics; classical mechanics; relativity; quantum mechanics; klassisk mekanik; kvantmekanik; relativitet; statistisk fysik; termodynamik; Fysicumarkivet A:1997:Jönsson;

    Abstract : Superdeformation, i.e. elongated shapes with the longest axis approximately twice as long as the shorter axes, has provided many new insights in nuclear structure. In this dissertation the possibility of forming superdeformed states related to two connected spheres, having a more or less pronounced neck, is investigated. READ MORE

  5. 3. Plant-availability of phosphorus removed from wastewater by different processes

    Author : Elisabeth Kvarnström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : The objective of this thesis was to investigate the plant-availability of P removed from wastewater by different processes, with focus on agronomic aspects. Short-term P availability was assessed by greenhouse studies, utilizing four different filter substrates and a sludge-recovered iron phosphate. READ MORE

  6. 4. Finding synergies for cancer treatment : new ways to modulate DNA damage repair by CX3CR1 and PFKFB3 inhibition

    Author : Jemina Lehto; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The goal of targeted cancer therapy is to selectively kill cancer cells based on their molecular survival mechanisms. DNA repair is as a promising cancer target as many cancers have chronic replication stress and deficiencies in the DNA damage response. READ MORE

  7. 5. Sample-to-answer paper-based nucleic acid amplification tests

    Author : Georgios Chondrogiannis; Mahiar Hamedi; Jeff Mold; Keith Pardee; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Nucleic Acid Amplification Tests (NAATs) with PCR technology to amplify DNA, are the golden standard for infectious disease diagnostics, but they require benchtop instruments and trained users to be performed. For this reason, we all had to send PCR test to centralized laboratories during the Covid-19 pandemic. READ MORE
