  1. 1. Out of the Dark and into the Light - Microscopic Analysis of Bright, Dark and Trapped Excitons

    Författare :Maja Feierabend; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; density matrix formalism; localized states; impurities; dark excitons; strain; transition metal dichalcogenides; Bloch equations;

    Sammanfattning : Atomically thin transition metal dichalcogenides (TMDs) have been in the focus of current research due to their efficient light-matter interaction, as well as the remarkably strong Coulomb interaction that leads to tightly bound excitons. Due to their unique band structure, TMDs show a variety of optically accessible bright and inaccessible dark excitons. LÄS MER

  3. 2. Mechanisms of microbial-host interaction during asymptomatic bacteriuria

    Författare :Jenny Grönberg Hernandez; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Asymptomatic bacteriuria; Urinary tract infection; Escherichia coli 83972; IRF3; TLR4; Evolution; host response; promoter polymorphisms; transcription; P fimbriae; Type 1 fimbriae;

    Sammanfattning : Urinary tract infections (UTIs) present an interesting and relevant model for studying microbial adaptation. After establishing significant numbers, the bacteria either cause severe disease, or an asymptomatic carrier state resembling the normal flora at other mucosal sites. LÄS MER

  4. 3. Analyses of genomic and gene expression signatures

    Författare :Rickard Sandberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Microarray; comparative genomics; differential gene expression; cell lines; computational biology;

    Sammanfattning : Biology has entered a challenging, information-intense period where computational experiments are complementing traditional experiments. A plethora of new techniques have allowed biological processes to be investigated on a global scale. LÄS MER

  5. 4. Molecular characterization of Mycobacterium tuberculosis isolates in Mozambique

    Författare :Sofia Omar Viegas; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Tuberculosis (TB) is one of the major health problems in Mozambique. It is estimated that 27,000 deaths caused by TB occur each year with an estimated incidence and prevalence rate of 431 and 504 per 100,000 population respectively. Mozambique ranks 19th on the list of 22 high-burden TB countries in the world. LÄS MER

  7. 5. Crustal architecture of the Kiruna mining district : Structural framework, geological modeling, and physical rock property distribution

    Författare :Ervin Csaba Veress; Tobias Bauer; Stefan Luth; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kiruna mining district; geological modeling; structural framework; common earth modeling; petrophysical characterization; mineral exploration; iron oxide-apatite; Ore Geology; Malmgeologi;

    Sammanfattning : Rapid technological advancements and growing environmental consciousness created a shifting dynamic of metal demand within the context of contemporary global challenges. The metals play a pivotal role in this transformation and remarkable surge in demand is expected. LÄS MER
