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

   Författare :Alex Basu; Natalia Ferraz; Pentti Tengvall; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

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

   Författare :Maria Palm; Ove Axelsson; Samar Basu; Charlotta Grunewald; Uppsala universitet; []
   Nyckelord :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

4. 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 :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.

5. 4. Studies on dephosphorisation during steelmaking

   Författare :Somnath Basu; Seshadri Seetharaman; Nobuo Sano; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process engineering; Metallurgisk processteknik;

   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).

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

   Författare :Supratim Basu; Chalmers tekniska högskola; []
   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
