  1. 1. EFFEKTER PÅ UPPSTRÖMSSTABILITETEN I FYLLNINGSDAMMAR : Ändrade porvattentryck till följd av cykliska magasinsnivåer

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

    Författare :Emma Widén; [2024]
    Nyckelord :Vattenfluktuationer; Släntstabilitet; Porvattentryck; Tolererat fel; Finita elementmetoden;

    Sammanfattning : Hydropower is one of the few energy sources with the ability to store a resource and thus regulate electricity production. When the water level in a reservoir changes, this affects the pore water pressures in the dam. LÄS MER

  3. 2. Microfluidic flow splitter shape optimization for high throughput

    Kandidat-uppsats, Lunds universitet/Avdelningen för Biomedicinsk teknik

    Författare :Christoffer Papamoustos Palmér; Joel Linder; [2023]
    Nyckelord :Genetic algorithms; Lab-on-a-chip; Optimization; Acoustofluidics; Microfluidics; Technology and Engineering;

    Sammanfattning : Due to an increasing incidence rate, the need for new effective methods for diagnosing cancer are of high importance. Studies have shown that circulating tumor cells, CTCs, have great potential as a diagnostic biomarker. Acoustophoresis is a label free method, capable of separating CTCs from red blood cells in a blood sample. LÄS MER

  4. 3. PARAMETRIC STUDY FOR WALL-TO-WALL CONNECTION IN MIXED STEEL CONCRETE STRUCTURES

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Simone De Troia; [2023]
    Nyckelord :;

    Sammanfattning : The objective of this thesis work is to study the connection between two Steel Concrete Structures (SCS) wall modules using embedded connection bars. The SCSs under investigation consist of two steel faceplates held together by tie bars, concrete is cast inside, and stress transmission between the concrete and the steel plates is provided by shear connectors as headed studs.

  5. 4. Methods to study device induced aggregation of proteins

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Marie Therese von Wowern; [2023]
    Nyckelord :protein formulation; protein aggregation; insulin; silicone oil; syringe; shear stress; subvisible particle; size exclusion chromatography; flow imaging microscopy; pharmaceutical technology; Technology and Engineering;

    Sammanfattning : This work developed a method for the investigation of how medical devices, such as syringes and needles, affect the formation of subvisible particles in a protein drug without excipients. Protein-based pharmaceuticals are well known to be sensitive to different kinds of stress, and exposure to stress during the use of this device is unavoidable. LÄS MER

  7. 5. Numerical analysis of a bearing strength in delaminated composite joint

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Olavi Kukkonen; [2023]
    Nyckelord :Bearing strength; Single-lap shear; Delamination; Countersinking; Hole size;

    Sammanfattning : Composite structures are commonly joined using adhesive or mechanical joints, withmechanical joints being preferred when components need to be removable for maintenancepurposes. However, the presence of mechanical joints introduces a discontinuity in theload path, which can serve as an initiation point for failure and needs to be taken intoaccount in the design of the joint.
