  1. 1. Surgical Site Infections in Dermatologic Surgery- Clinical, diagnostic, and pathogenic aspects

    Författare :Karim Saleh; Lund Dermatologi och venereologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgical site infections SSIs ; dermatologic surgery; full-thickness skin grafting; acute wounds; wound healing; microbiome; diagnostics; prevention; pathogenesis;

    Sammanfattning : Surgical site infections (SSIs) in dermatologic surge- ry contribute to unwanted healthcare costs and are complications that cause su ering in patients. The aim of this thesis was to explore clinical, diagnos- tic, and pathogenic aspects of SSIs in dermatologic surgery.In study I, we examined bacterial dynamics during normal wound healing and SSIs.

  3. 2. Rain water harvesting and supplemental irrigation at Sinjar district in northwest Iraq

    Författare :Saleh Zakaria; Rafid Alkhaddar; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Soil Mechanics; Geoteknik;

    Sammanfattning : Rainwater harvesting is one of the methods that can ensure availability of water for winter crop in Iraq. Using this technique the excess rainwater (runoff) is stored in reservoirs of dams of different sizes. The water from these reservoirs can be used later when required to satisfy the crops requirements. LÄS MER

  4. 3. Process and properties of continuous fibers based on cellulose nanocrystals and nanofibers

    Författare :Saleh Hooshmand; Tekla Tammelin; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : In recent years, composites made from natural fibers based on cellulose have received increasing attention since they have a low environmental impact and good mechanical properties. However, these fibers are short and discontinuous and the conventional spinning techniques used for these fibers results in continuous yarns with mechanical properties considerably lower than that of the single fibers.

  5. 4. Processing of continuous fibers based on nanocellulose: Influence of dispersion and orientation on mechanical properties

    Författare :Saleh Hooshmand; Stephen Eichhorn; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : The aim of the work was to prepare continuous bio-based fibers where nano-sized cellulose was used to improve the mechanical properties. Two different strategies were used to reach this aim, melt-spinning of thermoplastic fibers reinforced with nanocellulose and dry-spinning of cellulose nanofibers without solvent or chemicals.

  7. 5. Bipolar Silicon Carbide Integrated Circuits for High Temperature Power Applications

    Författare :Saleh Kargarrazi; Carl-Mikael Zetterling; Erik Lind; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Silicon Carbide (SiC) is suggested as a superior material for high temperature and high power electronic applications, thanks to its excellent properties. In this thesis, design and measurements of integrated circuits in bipolar 4H-SiC aiming for high temperature power applications are reported. LÄS MER
