  1. 1. Ion-Crosslinked Nanocellulose Hydrogels for Advanced Wound Care Applications

    Författare :Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; nanofibrillated cellulose; wood nanocellulose; ion crosslinking; hydrogel; wound healing; biocompatibility; blood interactions; bacterial interactions; protein carrier; nanotherapeutic; Engineering Science with specialization in Nanotechnology and Functional Materials; Teknisk fysik med inriktning mot nanoteknologi och funktionella material;

    Sammanfattning : A current trend in the field of wound care is the development of wound healing materials that are designed to address specific types of wounds or underlying pathologies to achieve improved healing. At the same time, there is a societal drive to replace synthetic materials with renewable alternatives. LÄS MER

  2. 2. Oxidative Stress, Angiogenesis and Inflammation in Normal Pregnancy and Postpartum

    Författare :Maria Palm; Ove Axelsson; Samar Basu; Charlotta Grunewald; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; inflammation; IL-6; F2-isoprostanes; oxidative stress; Pentraxin 3; PGF2α; PlGF; pregnancy; sFlt1; TNF-α; VEGF-A; Obstetrik och gynekologi; Obstetrics and Gynaecology; Medicinsk vetenskap; Medical Science;

    Sammanfattning : The aims were to investigate oxidative stress (I), angiogenesis (II) and inflammation (III-IV) in healthy women during pregnancy and postpartum. Oxidative stress was estimated by measurement of 8-iso-PGF2α and the antioxidants α- and γ-tocopherol. LÄS MER

  3. 3. Prostaglandins and Isoprostanes in Relation to Risk Factors for Atherosclerosis : Role of Inflammation and Oxidative Stress

    Författare :Johanna Helmersson; Samar Basu; Bengt Vessby; Tommy Cederholm; Uppsala universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Public health; prostaglandin F2α; F2-isoprostane; interleukin-6; C-reactive protein; serum amyloid A; tocopherols; cardiovascular risk factors; variation; inflammation; oxidative stress; human; Folkhälsomedicin; Public health medicine research areas; Folkhälsomedicinska forskningsområden;

    Sammanfattning : Inflammation and oxidative stress may be involved in atherogenesis. This thesis describes clinical studies of prostaglandin F2α (PGF2α), an inflammatory mediator, and the isoprostane 8-iso-PGF2α, a reliable indicator of oxidative stress, and cytokine-related inflammatory mediators and indicators in healthy subjects and in a population-based cohort of Swedish men.

  4. 4. Studies on dephosphorisation during steelmaking

    Författare :Somnath Basu; Seshadri Seetharaman; Nobuo Sano; KTH; []

    Sammanfattning : This work is aimed at understanding the thermodynamic principles influencing the phosphorus partition between slag and steel during steelmaking, particularly during refining of high-phosphorus hot metal using the basic oxygen steelmaking (BOS) process. Mapping of the slag path has been carried out using a mass balance model based on input conditions and off-gas analysis, which has been validated by intermediate measurements of slag and metal composition in an industrial basic oxygen furnace (BOF).

  5. 5. Single Phase Active Power Factor Correction Converters - Methods for Optimizing EMI, Performance and Costs

    Författare :Supratim Basu; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Antenna Factor; Diode Recovery Time; Harmonic currents; EMI; Quasi Park; Snap Factor; PFC;

    Sammanfattning : In this thesis, front-end solutions with single-phase power factor correction (PFC) capability are studied. The reduction of current harmonics using various PFC techniques is investigated and related to the EN 61000-3-2 standard. LÄS MER
