  1. 1. Adapted data collection in field utilizing RMR and the Q-system

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Amanda Olsson; [2024]
    Keywords : Rock mass classification; Q-slope; SMR; Slope stability;

    Abstract : The focus on slope stability has increased rapidly in Norway over the last years due to several unwanted landslides. In Norway, the most used method today to classify the rock mass and to determine the required reinforcement, is the Q-system. In addition to that the RMR method is also a commonly used method.

  3. 2. Implementation of Level of Development for BIM Collaboration in Timber Building Subsystems Design: A Case Study of I-Joist Construction Elements

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Isabell Gustafsson; [2024]
    Keywords : BIM; I-Joist; LOD; Level of Development; Timber Building Subsystems;

    Abstract : Due to time, cost, and environmental challenges, wood has become a more common building material even for more complex buildings. Implementing the concept of Level of Development (LOD) on timber structures could provide a tool for BIM collaboration that may save cost and time, and in the early stages mediate wood as an available building material.

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

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Vilma Nordh; [2024]
    Keywords : Numerical modelling; wedge stability; 3DEC; UnWedge;

    Abstract : 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.

  5. 4. Exploring alternative surfactants to replace PEG within lipid nanoparticles

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master); Lunds universitet/Bioteknik (CI); Lunds universitet/Bioteknik (master)

    Author : Elina Edidovica; [2024]
    Keywords : Lipid nanoparticle; polyethelyne glycol PEG ; alpha-tomatine; N-hexadecyl beta d-maltoside HDM ; DOPC; DPPC; cholesterol; film hydration; stability study; DLS; Cryo-TEM; SAXS; pharmaceutical formulation; Chemistry;

    Abstract : Over the past decade an increasing amount of studies has demonstrated that PEGylation not only precipitates reductions in drug delivery efficiency but also triggers the immune system to produce antibodies, specifically anti-PEG antibodies. The objective of my thesis is to explore alternative surfactants that could viably replace PEG within lipid nanoparticles. READ MORE

  6. 5. FE-Modelling of Composite Girder tests

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Holger Berggren; Bergstedt Ola; [2024]
    Keywords : shear connector; post-installed; coiled spring pins; composite girder; partial composite action; finite element method;

    Abstract : Many of the existing steel-concrete bridges may need to be strengthened, as heavier vehicles areallowed on the Swedish roads. These bridges could possibly be strengthened by post-installingshear connectors. The shear connectors may enhance the load-bearing capacity through a higherdegree of composite action between the steel and concrete interface. READ MORE
