  2. 21. Anionic Graft Copolymers with Poly(ethylene oxide) Side-Chains; Synthesis, Solution Properties and Ion Conduction

    Author : Helene Dérand; Centrum för analys och syntes; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dieletric properites; ion conduction; solution properties; aggregation; amphiphilic polymers; poly ethylene oxide ; preparation; grafting; Polymer technology; biopolymers; Polymerteknik;

    Abstract : The research underlaying this thesis involves synthesis and characterization of well-defined anionic graft copolymers carrying poly(ethylene oxide) (PEO) side-chains. Two different grafting techniques were used. Backbone polymers were prepared through radical terpolymerization of maleic anhydride, styrene and an additional comonomer. READ MORE

  4. 22. Treatment of coagulopathy in patients with critical COVID-19

    Author : Sandra Jonmarker; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Introduction: Thromboembolic complications affect a large proportion of patients with critical COVID-19, and it may be associated with an increased risk of death. It has been hypothesized that both the virus of SARS-CoV-2 itself and the inflammation caused by the infection puts patients in a pro-coagulative state. READ MORE

  5. 23. Gestational age and size at birth and risk of esophageal inflammation and cancer

    Author : Lina Forssell; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: In a hypothesis generating study by my colleagues a 7-fold increase in the risk of esophageal adenocarcinoma (EAC) was found in a cohort of individuals born preterm or with a low birth weight. Preterm born individuals regurgitate more than term born infants, and infant gastroesophageal reflux disease (GERD) might continue into childhood and even adulthood. READ MORE

  6. 24. Nutritional and physicochemical characterisation of dietary fibre in wheat fractions

    Author : Lina Haskå; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; dietary fibre; fructan; arabinoxylan; wheat; distillers grains; short-chain fatty acids; microbiota;

    Abstract : Dietary fibre is fermented in the colon to short-chain fatty acids (SCFAs), of which especially butyric and propionic acid may have health-promoting effects. One source of dietary fibre may be by-products from wheat, which are currently used as animal feed. READ MORE

  7. 25. Treatment technologies for human faeces and urine

    Author : Charles Niwagaba; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis examines simple, cheap, environmentally friendly and resource efficient technologies for the treatment of source-separated human faeces and urine to enable safe recycling of their plant nutrients for plant production in developing countries. Composting of faeces-to-food waste (F:FW) in wet weight mix ratios of 1:0, 3:1 and 1:1 was studied in 78 L reactors insulated by 25 mm styrofoam; and of F:FW in wet volume/weight ratios of 1:0, 1:1 and 1:3 in 216 L reactors insulated by 75 mm styrofoam.
