  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 facilitatethe identification of main water-bearing units (e.g. LÄS MER

  2. 2. Modelling gross primary production in semi-arid regions: effects on carbon uptake of intensive agriculture in southern Kenya

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Malin Ahlbäck; [2020]
    Nyckelord :Physical Geography; Ecosystem Analysis; GPP; Africa; Kenya; Land cover changes; Cropland; Remote sensing; Sentinel-2; Earth and Environmental Sciences;

    Sammanfattning : Background and aim: Gross primary production (GPP) is the largest global carbon (C) flux and an important component for counteracting anthropogenic CO2 emissions, understanding vegetation dynamics, and sustaining universal human standards. Africa plays a prominent role in the global C cycle, though our understanding of GPP dynamics is largely hampered by a paucity of ground-based observations. LÄS MER

  3. 3. A pragmatic approach to improve the efficiency of the waste management system in Stockholm through the use of Big Data, Heuristics and open source VRP solvers : A real life waste collection problem;Stockholm’s waste collection system and inherent vehicle routing problem, VRP

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Rafael Salcedo Villanueva; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis, we will address a real life waste collection problem; Stockholm’s waste collection system and inherent vehicle routing problem, VRP. To do this we will first delve into some mathematical theory of Combinatorial Optimization and Heuristics to understand the fundamentals of the problem. LÄS MER

  4. 4. Development and validation of a novel quantitative PCR analysis method for HIV-1

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Teoretisk kemi

    Författare :Josefine Sundgren; [2020]
    Nyckelord :HIV-1; qPCR; Octapharma; Taqman; applied biochemistry; tillämpad biokemi; Technology and Engineering;

    Sammanfattning : The major problem when developing primers and probe sets for detection of HIV-1 is its high genetic variability and strong ability to mutate. HIV-1 is divided into four groups, M, N, O, P based on genetic similarities, and there are more than 70 different circulating recombinant forms. LÄS MER

  5. 5. Soil organic carbon prediction using Sentinel-2 data and the LUCAS topsoil database

    Kandidat-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Philipp Hansen; [2020]
    Nyckelord :Sentinel-2 LUCAS topsoil database Soil organic carbon mapping Multispectral data; Earth and Environmental Sciences;

    Sammanfattning : Its carbon sink potential as well as soil fertility benefits make organic carbon a soil variable for which reliable quantification methods are sought. This thesis work aims at investigating the possibility of adapting a large soil spectral library to build models for SOC predictions with remotely sensed, multispectral data. LÄS MER
