  1. 1. Urea-Based Treatments of Unretted Hemp Fibres from Residual Streams

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Danilo Esteban Ortiz Sarasty; [2023]
    Nyckelord :Finola waste; stalks; unretted hemp fibres; degumming; cold urea alkali; microwave-urea;

    Sammanfattning : More sustainable and efficient degumming methods are required to extract finner bast fibres, especially from agro-industrial waste streams such as stalks from hemp for food purposes. For this reason, in this study, two urea-based treatments were evaluated as degumming alternatives for unretted hemp fibres from residual streams, one at cold and alkaline conditions (CUA) and the other in combination with microwave radiation (MWU).

  3. 2. Development of verified FE simulation method on crimp joint with gasket : A combined experimental and numerical study

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Erik Andraéy; [2021]
    Nyckelord :Method development; Radiator; Experimental Stress Analysis; Structural Analysis; Falsförband; Metodutveckling; Radiator; Experimentell Spänningsanalys; Strukturanalys;

    Sammanfattning : When developing drivetrain cooling modules for commercial vehicles, the top priority is the strength of the products. The reason lays within the structural change that companies are undergoing where the warehouses are minimized and the companies are relying on the transportation of commercial vehicles. LÄS MER

  4. 3. Development of headspace solid phase microextraction gas chromatography mass spectrometry method for analysis of volatile organic compounds in board samples : Correlation study between chromatographic data and flavor properties

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Thea Zethelius; [2021]
    Nyckelord :Solid phase microextraction SPME ; method development; volatile organic compounds VOCs ; food contact material FCM ; flavor experience; design of experiment DoE ; multivariate analysis;

    Sammanfattning : The purpose of this thesis work was to develop a headspace solid phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) method to detect volatile organic compounds (VOCs) in board samples and to statistically investigate potential correlation between chromatographic data and flavor data obtained from a trained panel. The developed method would hopefully serve as a complement to the already established routine analyses at Stora Enso and gain an increased understanding of which VOCs in the board influence its flavor properties.

  5. 4. Virtual characterization of composite materials for aero-engine components

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Facundo Masari; [2020]
    Nyckelord :Composite; simulation; multiscale; modelling; UD; NCF; prepreg; aerospace; engine;

    Sammanfattning : Since its beginnings, the aerospace industry has been interested in lowering the weight of aircraft. Moving from performance and economic drivers to environmental design parameters, the weight has continuously been a major focus for this industry. LÄS MER

  7. 5. Finger flexion and wrist extensor capacities in swedish climbers, related to strength, endurance and injury

    Magister-uppsats, Umeå universitet/Avdelningen för idrottsmedicin

    Författare :Kristoffer Lindbäck; [2020]
    Nyckelord :Climbing; Finger flexion; Half-crimp; injuries; Wrist extension;

    Sammanfattning : Climbing is a rapidly growing sport, and the inclusion in the 2021 Olympics will further push the popularity.  The numerous originalities of Sport climbing (SC) is the intense use of finger, hands and forearms to displace the body on vertical to fully overhangning wall profiles.
