  1. 1. Infiltration, hydrogeology, and heterogeneity - Management of pressure and flow: A case study for the Varberg tunnel project

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Lisa Risby; [2020-07-08]
    Nyckelord :short duration hydraulic tests; hydraulic conductivity; radius of influence; infiltration; heterogeneity; confined and unconfined aquifer;

    Sammanfattning : This thesis aims to describe a conceptual model of the sedimentology for Swedish (or nordic) conditions of heterogeneous aquifers but focus is on a case study in Varberg. This to facilitate the identification of main water-bearing units (e.g. LÄS MER

  3. 2. Property prediction of super-strong nanocellulose fibers

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Maria Abada; Elin Fossum; Louise Brandt; Anton Åkesson; [2020]
    Nyckelord :Cellulose nanofibril CNF ; Spinning; Flow-stop; Flow-focusing; Mechanical properties; Carboxymethylation; TEMPO-oxidation;

    Sammanfattning : The innovative technology behind production of strong biofilaments involves the process of spinning filaments from nanoparticles extracted from wood. These nanoparticles are called cellulose nanofibrils (CNFs). LÄS MER

  4. 3. Optical Coherence Tomography measurements of biofibril dispersions in flow-focusing

    Master-uppsats, KTH/Mekanik

    Författare :Cecilia Rydefalk; [2019]
    Nyckelord :;

    Sammanfattning : Microfluidic spinning techniques have been used as a successful assembly process for biofibrils dispersed in a fluid. The dispersion flows through a microchannel and is focused by a sheath flow. In this way the topology and velocity of the dispersion in the core can be manipulated. LÄS MER

  5. 4. Värdeflödesanalys i Processindustrin : En fallstudie på Cementa AB Skövde

    M1-uppsats, Högskolan i Jönköping/JTH, Industriell organisation och produktion

    Författare :Ylva Nilsson; Victoria Överli; [2018]
    Nyckelord :Processindustri; Värdeflödesanalys; SME; Kapacitet; Trumma-Buffert-Rep; Underhåll;

    Sammanfattning : Purpose – The purpose of the study is to investigate how value stream mapping can identify improvement proposals in a process industry's material flow focusing on capacity. To achieve the purpose of the study, three questions have been formulated. LÄS MER

  7. 5. Assembly of whey protein nanofibrils into macroscopic filaments

    Master-uppsats, KTH/Mekanik

    Författare :Kamada Ayaka; [2015]
    Nyckelord :;

    Sammanfattning : Recently, it has been reported that the increasing number of plastic are significantly floated in the sea, because they are difficult to be degraded naturally. This lack of biodegradability requires us to develop new environmental-friendly material replacing current plastics. LÄS MER
