  1. 1. Dark pathways : cows’ walking behavior in dim light environments

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Kajsa Ståhlberg; [2022]
    Nyckelord :night light; illumination; locomotion; activity; intensity; color; distribution; obstacle course;

    Sammanfattning : Swedish dairy cows should have access to dim light at night according to the animal welfare act, but there are no further recommendations stated for dim light management regarding light intensity, light color, or light distribution. This study aimed to examine the effects of five dim light intensities, in red and white light color, and in even and uneven light distribution on cows’ walking behavior in an obstacle course.

  3. 2. Heteroleptic Copper (I) Complexes as Photosensitizers in Dye-Sensitized Solar Cells

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Angela Raffaella Pia Pizzichetti; [2019]
    Nyckelord :Dye-Sensitized Solar Cells; Chemical and Environmental Engineering; Photovoltaic; Copper I complexes;

    Sammanfattning : Modern civilization highly depends on energy and finding alternative sources to fossil fuels becomes more and more necessary. The sun is the most abundant energy source available and exploiting it efficiently would result in a great environmental and economic breakthrough. LÄS MER

  4. 3. Spatial resolution threshold in layers and red jungle fowls : are there differences due to light intensity or light spectra?

    Master-uppsats, SLU/Dept. of Animal Environment and Health

    Författare :Pauline Annerstedt; [2018]
    Nyckelord :spatial resolution threshold; layer; red jungle fowls; visual acuity;

    Sammanfattning : The domestic fowl (Gallus gallus domesticus) originates from the forests in South-east Asia. It may be correct to assume that the visual system of the domestic fowl is still adapted to light that is filtered through the green forest canopy. LÄS MER

  5. 4. Noise modelling for high-throughput super-resolution microscopy

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Xavier Casas Moreno; [2018]
    Nyckelord :;

    Sammanfattning : Super-resolution fluorescence microscopy is an emerging imaging fieldthat aims at breaking the di↵raction barrier of light based on state transitionin fluorescent molecules. Current challenges in the existing approachare to achieve large field of views, fast recordings and increasing the imagequality. LÄS MER

  7. 5. The behaviour and movement of dairy calves in low light intensities

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Emelie Battersby; [2016]
    Nyckelord :light intensity; calves; behaviour; locomotion;

    Sammanfattning : According to the Swedish welfare act, cattle stables must have inlet of natural light and artificial light that do not disturb the animals’ natural behaviour and diurnal rhythm, dairy cows should also be provided with light at night. However, there are no specific recommendations on light programs for calves. LÄS MER
