  1. 1. Rock Wedge Stability Assessment : A Comparative Analysis of Limit Equilibrium and Discrete Element Methods

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Vilma Nordh; [2024]
    Nyckelord :Numerical modelling; wedge stability; 3DEC; UnWedge;

    Sammanfattning : Rock wedge stability is a common concern in underground excavations. Since the wedge stability influences the support design, it is important to use a wedge stability analysis method that can capture factors like excavation geometry, joint parameters and properties, rock mass properties, rock cover, and stress field as accurately as possible.

    Sammanfattning : Syntetiska material står idag för merparten av produktionskedjan för textilmaterial globalt. Behovet av biobaserade regenererade fibrer ligger i framkant när det gäller framtida val för produktion av textilmaterial i samband med målen för hållbar utveckling. LÄS MER

  5. 4. Structural and Functional Characterisation of the Human Mitochondrial Pyruvate Carrier

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Simon Gripvall; [2023]
    Nyckelord :biochemistry; complex; MPC; proteoliposomes; pyruvate; transport; Chemistry;

    Sammanfattning : The metabolism of pyruvate in the cell is abnormally regulated in several human diseases, such as type-II diabetes, cancer and neurodegenerative disorders, in which the human mitochondrial pyruvate carrier (HuMPC) sits at a pivotal point. It transports pyruvate across the inner mitochondrial membrane and consists of two proteins, MPC1 and MPC2, and is a potential drug target against these diseases. LÄS MER

  7. 5. Effective shear stiffness of cross-laminated timber : Comparison between numerical and analytical approaches

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Therese Badrous; Las Muradi; [2023]
    Nyckelord :;

    Sammanfattning : The increasing importance of sustainability has led to a focus on smart solutions for energy consumption and materials. Cross-laminated timber (CLT) has gained attention as a sustainable alternative in construction, offering high strength, stiffness, and dimensional stability. LÄS MER
