  1. 1. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?

    Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Författare :Andreas Vernby; [2021]
    Nyckelord :Hydropeaking; geological substrate; aquatic macroinvertebrates; EPT species; Hester-Dendy samplers; Korttidsreglering; geologiskt substrat; akvatiska makroevertebrater; EPT; Hester-Dendy-provtagare;

    Sammanfattning : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. LÄS MER

  3. 2. Sammansättning av funktionella födosöksgrupper hos akvatiska insekter i vattendrag med och utan korttidsreglering

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

    Författare :Pontus Hindrikes Bergström; [2021]
    Nyckelord :Functional feeding groups; Aquatic invertebrates; FFG; Shredders; Grazers; Gatherers; Filter feeders; Predators; Hydropeaking; EPT; Funktionella födosöksgrupper; Korttidsreglering; akvatiska insekter; FFG; EPT;

    Sammanfattning : Hydropeaking is important to meet peak demand of electricity on the Swedish powergrid. The rapid changes in discharge may affect the ecology of streams and rivers negatively downstream of hydropeaking powerplants. LÄS MER

  4. 3. Automatic magnetic resonance brain volume measurements to assess the effect of minimised blood sample extraction on brain development in extremely preterm infants

    Master-uppsats, Lunds universitet/Läkarutbildningen

    Författare :Hickmat Hamie; [2021]
    Nyckelord :Magnetic resonance imaging; Brain development; Prematurity; Medicine and Health Sciences;

    Sammanfattning : Aim: To evaluate a pipeline for automatic MRI brain segmentation and volumetric tissue structure quantification in a cohort of extremely preterm infants. Methods: 13 extremely preterm neonates underwent MRI-scanning at a term equivalent age. Seven of these subjects had suitable MRI sequences and were analyzed in the pipeline. LÄS MER

  5. 4. Social Movement Effects on the Market Economy : The Impacts of Anti-Extradition Law Amendment Bill movement on Hang Seng Properties index

    Master-uppsats, KTH/Fastigheter och byggande
