  1. 1. Ecological impacts of dam removal in Swedish inland waters : Effects on water chemistry and fish demography

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

    Författare :Johanna Ekman; [2023]
    Nyckelord :biology; ecology; dam removal; Sweden; impact; inland waters; ecosystem; water chemistry; fish demography; Perca fluviatilis; European perch; biologi; ekologi; dammutrivning; Sverige; påverkan; inlandsvatten; ekosystem; vattenkemi; fiskdemografi; Perca fluviatilis; abborre;

    Sammanfattning : Dams play an important role in our society, but their negative impacts on aquatic ecosystems have led to a need for conservation efforts to mitigate the negative effects. In some instances, dam removal has been suggested to be the most economically and ecologically beneficial restoration method to improve longitudinal connectivity. LÄS MER

  3. 2. Cell Identification from Microscopy Images using Deep Learning on Automatically Labeled Data

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Fredrik Salomon-Sörensen; [2023]
    Nyckelord :Deep Learning; Cell Identification; Image Segmentation; Nuclei Segmentation; Convolutional Neural Networks; UNet; Image Analysis; Microscopy; Noisy Labels; Phase-Contrast; Automatic Labeling; Technology and Engineering;

    Sammanfattning : In biology, cell counting provides a fundamental metric for live-cell experiments. Unfortunately, most researchers are constrained to using tedious and invasive methods for counting cells. Automatic identification of cells in microscopy images would therefore be a valuable tool for such researchers. LÄS MER

  4. 3. När bildas is? : En studie om ispredicering och faktorer som påverkar isbildning

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Dennis Berglund; [2023]
    Nyckelord :Frazil ice; temperature; ice-prediction; accumulated degree-days.;

    Sammanfattning : An improved knowledge regarding what spatial scale temperature data is needed for ice-prediction would improve calculations how ice-coverage has been affected over time. Which by extension would give insight how ice might response to climate change. LÄS MER

  5. 4. Samband mellan nukleära avvikelser i tvåcellsstadiet hos embryon efter assisterad befruktning och chans till graviditet och levande fött barn

    Kandidat-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

    Författare :Helbeen Sadullah; [2023]
    Nyckelord :Assisted fertilization; nuclear errors; multinuclearity; embryo assessment; Assisterad befruktning; nukleära avvikelser; multinukleäritet; embryobedömning;

    Sammanfattning : Bakgrund Assisterad befruktning är en vanlig behandling för infertilitet, vilket innebär oförmågan att bli gravid. Vid assisterad befruktning övervakas embryoutvecklingen med hjälp av Time Lapse Imaging-teknologi i en EmbryoScope och implantationsförmågan bedöms. LÄS MER

  7. 5. Generative Modelling and Probabilistic Inference of Growth Patterns of Individual Microbes

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Shashi Nagarajan; [2022]
    Nyckelord :Generative modelling; probabilistic inference; Nuisance Variable Elimination; Variational Inference; microfluidic single cell cultivations;

    Sammanfattning : The fundamental question of how cells maintain their characteristic size remains open. Cell size measurements made through microscopic time-lapse imaging of microfluidic single cell cultivations have posed serious challenges to classical cell growth models and are supporting the development of newer, nuanced models that explain empirical findings better.
