  1. 1. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Anna Wagne; [2023]
    Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Sammanfattning : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. LÄS MER

  3. 2. Utläckage från vattennät – en betydande källa till tillskottsvatten i spillvattennät? : Linjär regressionsanalys av VA-data från svenska kommuner

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Anna Ringqvist; [2021]
    Nyckelord :I I water; infiltration; non-sewer water; water leakage; wastewater system; linear regression; statistics; data analysis; tillskottsvatten; dricksvattenläckage; utläckage; spillvattennät; dricksvattennät; ledningsnät; VA; avloppsvatten; VASS; linjär regression; statistik; dataanalys;

    Sammanfattning : Infiltration and inflow of non-sewer water to wastewater systems (I/I water) poses a significant problem to health, economy, and the environment by affecting the capacity of the wastewater system. To determine effective measures to reduce the amount of I/I water, it is essential to identify its most important sources. LÄS MER

  4. 3. Automation Pipelines for Efficient and Robust Experimental Research Within Cognitive Neuroscience

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för visuell information och interaktion

    Författare :Patrik Björklund; Anna Rydin; [2020]
    Nyckelord :Computer Vision; Visual Analog Scale; VAS; Questionnaires; Research Pipeline; Automation; Anomaly Detection;

    Sammanfattning : The current trend towards large-scale research projects with big quantities of data from multiple sources require robust and efficient data handling. This thesis explores techniques for automatizing research data pipelines. Specifically, two tasks related to automation within a long-term research project in cognitive neuroscience are addressed.

  5. 4. Didaktiska arter

    Kandidat-uppsats, Institutionen för livsvetenskaper

    Författare :Anna Hylin; [2012]
    Nyckelord :Didactical indicator species; water quality; wetland; ecological niche; Didaktiska indikatorarter; vattenkvalitet; våtmark; ekologisk nisch;

    Sammanfattning : The study intends to find easily recognizable indicator species for water quality in the constructed wetland of Flemingsbergsviken. The study is relevant since indicator species can be difficult to determine for common people. LÄS MER

  7. 5. Structural model of the Lambarfjärden area from surface and subsurface data in connection with the E4 Stockholm bypass

    Master-uppsats, Berggrundsgeologi

    Författare :Anna Vass; [2012]
    Nyckelord :Lambarfjärden; sturctural model; fracture; E4 Stockholm Bypass;

    Sammanfattning : The present Master thesis is written in connection with the E4 Stockholm bypass, which is a future motorway linking northern and southern Stockholm, and will mostly run through tunnels. The bypass will cross the Lake Mälaren in the Lambarfjärden area, where a fault is indicated on the geological maps, which would create risks for tunneling. LÄS MER
