  1. 11. Does in vivo exposure to perfluorooctanesulfonicacid induce an altered colonic barrier function inmice?

    University essay from Örebro universitet/Institutionen för medicinska vetenskaper

    Author : Hanna-Dalia Laar; [2022]
    Keywords : PFOA; PFAS; Ulcerative colitis; colon barrier; gastrointestinal permeability; Ussing Chamber;

    Abstract : Background: Several environmental risk factors have been implicated in the pathogenesis ofinflammatory bowel disease (IBD) and might cause an altered barrier function, a hallmark ofIBD. Recent evidence suggests that patients with late-onset ulcerative colitis (UC) have anincreased serum level of perfluoroalkyl substances (PFAS), one of the major chemical groupscontaminating our diet.

  3. 12. Axially loaded screw joints in wooden structures exposed to fire : Fire tests in furnace and numerical calculations in TASEF of different screw mounting variations

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Henrik Pettersson; Emma Wiklund; [2022]
    Keywords : Fire; wood; screw joints; strength; temperature; TASEF; Brand; trä; skruvförband; bärförmåga; temperatur; TASEF;

    Abstract : To achieve sufficient stability of a structure in a fire scenario, a thorough design of joints in wooden structures are as important as the design of the construction itself. As an earlier study points out, there are no existing design method available to determine the load capacity of an axially loaded screw joint in wooden structures, which complicate the process of a thorough design of the joint in a fire scenario.

  4. 13. Sustainable Swedish Industry by Improved Excess Heat Recovery

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Erik Rosengren; [2022]
    Keywords : Excess Heat Recovery; Black Liquor Evaporation; Pulp and Paper; Retrofit; Agenda 2030; Water Technology; Resource Management; Waste Heat; Technical Validation; Chemical Engineering; Water Savings; Energy Efficiency; Greenhouse Gas mitigation; Spillvärme; Indunstning; Svartlut; Pappersmassaindustri; Energieffektivisering; Technology and Engineering;

    Abstract : Achieving a sustainable Swedish industry will require better utilization of resources already available and already spent. Nationally, vast amounts of heat are released into the atmosphere and not made use of. READ MORE

  5. 14. Interaction between cobalt nanoparticles and DPPC at pulmonary conditions

    University essay from KTH/Yt- och korrosionsvetenskap

    Author : Paula Sommer; [2021]
    Keywords : metallic nanoparticles; lipids; lung surfactants; adsorption; pulmonary fluid; metalliska nanopartiklar; lipider; lungtensider; adsorption; syntetisk lungvätska;

    Abstract : Nanomaterial produceras och används alltmer i tekniska lösningar för att förbättra t.ex. materialegenskaper. Eftersom ett materials egenskaper förändras när det är i nanoskala så påverkas även dess toxikologiska egenskaper. READ MORE

  6. 15. Potential Application of Multiplex Automated Genome Engineering (MAGE) and One-Step Curing Plasmid System for Environmental Cambodian Enterobacterial Isolates

    University essay from Uppsala universitet/Institutionen för medicinsk biokemi och mikrobiologi

    Author : Olivia Alexandra; [2021]
    Keywords : Antimicrobial resistance; plasmid curing; environmental isolates; recombineering; enterobacteria;

    Abstract : Antimicrobial resistance (AMR) is concerning because it limits antimicrobial drug treatment options. AMR occurs by the overuse and misuse of antimicrobial drugs. In environmental settings, AMR can disseminate from places of high use, which leads to increased exposure to humans and animals. READ MORE
