  1. 1. Does turbidity affect critical thermal maximum (CTM) of mussels : Behavioural changes in Unio tumidus under stress

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Ellinor Karlsson; [2022]
    Nyckelord :CTM; critical thermal maximum; turbidity; suspended solids; Unio tumidus; freshwater mussel; bivalve; climate change; Unionida; CTM; turbiditet; grumlighet; suspenderade ämnen; Unio tumidus; sötvattensmussla; musslor; klimatförändringar; Unionida;

    Sammanfattning : Freshwater mussels is one the most endangered groups of organisms worldwide and stand in front of several threats. Global warming along with anthropogenic influence affect the mussel’s natural habitat and stress leads to changes in their behaviour. LÄS MER

  3. 2. High contrast imaging through turbid media using Fourier filtering and phase retrieval algorithm

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Sam Taylor; [2022]
    Nyckelord :;

    Sammanfattning : Fourier filtering is a powerful technique to improve the contrast when imaging through turbid media. However, the trade-off between contrast and spatial resolution is a long-standing issue that limits the Fourier filtering technique to low spatial resolution requirements. LÄS MER

  4. 3. The influence of molecular structure of phospholipids on the transition from micelles to bilayers in bile salt surfactant/phospholipid mixtures

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för läkemedelskemi

    Författare :Zeyneb Alkademi; [2020]
    Nyckelord :phospholipids; micelles; bilayers; bile salt; surfactant;

    Sammanfattning : Phospholipid molecules self-assemble to form bilayers that are poorly soluble in an aqueous solvent. Phospholipids may, however, be readily dissolved by mixing with a bile salt or amphiphilic drug surfactant that forms mixed surfactant/phospholipid micelles. LÄS MER

  5. 4. How robust is water quality determination with optical measurements for highly polluted agricultural waters?

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Honorine Uwera; [2020]
    Nyckelord :turbidity; suspended sediments; dissolved organic matter; optical measurements;

    Sammanfattning : Optical technology is used to measure and monitor water quality, to date mainly in drinking water treatment, where water is typically much cleaner than in heavily polluted agricultural streams. To characterize suspended sediments (SS) and dissolved organic matter (DOM) in surface water some optical measurements have been used (absorbance and fluorescence spectroscopy). LÄS MER

  7. 5. Optical communication with underwater snake robots : Design and implementation of an underwater wireless optical communication system

    Master-uppsats, Mittuniversitetet/Institutionen för elektronikkonstruktion

    Författare :Jaime Marco Rider; [2019]
    Nyckelord :optical communications; underwater wireless; robot communications;

    Sammanfattning : Eelume AS is a norwegian company that develops autonomous underwater vehicles. Their flagship model is an underwater snake robot that performs inspection, maintenance and repair operations. For the time being, Eelume has been using acoustic communications between their AUV's and the docking station, but it has a big drawback: bandwidth. LÄS MER
