  1. 1. Enhancing the stability of probiotics: Freeze-drying and encapsulation

    Författare :Shuai Bai; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; freeze-drying; lyophilization; L.ruteri; Probiotics; Lyoprotectant; Structure; Encapsulating material; Pore size; Material thickness; SEM; Tomography; Storage stability; Amorphous sugars; Glass transition temperature; DSC;

    Sammanfattning : This research dives into the intricate world of freeze-drying, an essential process in pharmaceutical and probiotic industries, to better understand the factors affecting probiotic stability during storage. The process of freeze-drying and the composition of freeze-dried products significantly affect the stability of probiotics, yet factors such as the material’s encapsulation properties remain relatively unexplored, demanding further research.

  3. 2. MUSCLE TONE IMBALANCE IN HUMAN UPPER EXTREMITY An experimental study of muscle adaptation to altered tension

    Författare :Fredrik Einarsson; Göteborgs universitet; []
    Nyckelord :muscle biopsy; freeze storage; upper extremity; shoulder; human muscle; sarcomere; stress-strain relationship; stress relaxation; stiffness; elasticity; mechanical testing; morphology; spasticity; obstetric brachial plexus palsy; rotator cuff tear; tendon transfer;

    Sammanfattning : Aim: The aim of this thesis was to improve outcome after tendon transfer and rotator cuff surgery by investigating the impact on response to passive mechanical testing and change in structural characteristics associated with longstanding changes in the tension of skeletal muscle in the human upper extremities in vivo. Patients and methods: The investigational method was in vitro assessment of human upper extremity muscles. LÄS MER

  4. 3. Food ingredients from cultivated seaweeds-Improving storage stability and protein recovery

    Författare :Hanna Harrysson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unsaturated fatty acids; macroalgae; alterative cultivation; sequential recovery; pH-shift; ascorbic acid; long-term storage; Seaweed; protein extraction; proteins; lipid oxidation;

    Sammanfattning : There is a global demand for new vegetarian protein sources, and seaweed have for multiple reasons been identified as a promising candidate. The overall aim of this thesis was to evaluate the potential of three different Swedish seaweed species as food protein sources, but also as sources of unsaturated fatty acids, vitamins and minerals.

  5. 4. Trees to supercapacitors: green energy storage for sustainable future

    Författare :Bony Thomas; Kristiina Oksman; Mohini Sain; Milo Shaffer; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Trä och bionanokompositer; Wood and Bionanocomposites;

    Sammanfattning : Currently the world is transitioning to a fossil free and circular economy-based development to achieve the environmental and climate objectives along with the sustainable development goals. To achieve this target, efficient use of resource materials is important, which can increase the lifetime and economic value of the resources while decreasing both the extraction of new raw materials and landfill waste.
