   University essay from Lunds universitet/Institutionen för arkitektur och byggd miljö; Lunds universitet/Avdelningen för Energi och byggnadsdesign

   Author : Rebecka Ståhl; Parvathy Biju; [2023]
   Keywords : Alertness; Circadian Entrainment; Clear Sky; Correlated Colour Temperature; Daylighting; Direct Electric Lighting; Direct-Indirect Electric Lighting; Energy-Efficiency; Grasshopper; Integrative Lighting; LARK 2.0; Melanopic Equivalent Daylight Illuminance; Overcast Sky; Photopic Illuminance; Spectral Power Distribution.; Technology and Engineering;

   Abstract : Human beings in modern society spend more than 90% of their time indoors to live, work, and socialize. To improve health, quality of life and task performance, integrative lighting is designed to give the right light at the right time at the eye to stimulate circadian entrainment. READ MORE

3. 2. Building Orientation and Non-Image Forming Effects of Light. Connecting Simulation and reality in the case of Iggesund School.

   University essay from KTH/Ljusdesign

   Author : Gregor Ruta; [2022]
   Keywords : Alfa-Opic Metrics; Spectral Diet; OWL – Occupant Well-being through Lighting; Chronobiology; Daylight; Circadian Rhythmes; Melatonin; Vision;

   Abstract : In recent years there has been an increase in the number of apartments in Sweden. The officials are estimating that approximately 1000 primary schools need to be built to meet the 20% increase in students. Facing the rising demand; my thesis makes a contribution to sustainable school design via optimisation of the building orientation. READ MORE

4. 3. Geographic variations in treatment of sleeping disorders in children focusing on melatonin and weighted blankets in Sweden

   University essay from Örebro universitet/Institutionen för medicinska vetenskaper

   Author : Jennifer Berglöf; [2022]
   Keywords : sleeping disorders; children; weighted blankets; melatonin; sleep hormone;

   Abstract : Introduction: Sleeping disorders are common in the paediatric population. Geographic data over prescription of melatonin exist in Sweden but no collected data exists over prescription of weighted blankets (WB). It has been hypothesised that WB can lower the usage of sleeping medication, but possible correlations to melatonin have not been defined. READ MORE

5. 4. Effects of melatonin and Single Layer Centrifugation on cryosurvival of ram semen samples

   University essay from SLU/Dept. of Clinical Sciences

   Author : Lea Enenkelová; [2021]
   Keywords : sheep reproduction; Jezersko-Solčava sheep breed; colloid centrifugation; melatonin;

   Abstract : The composition of the ram sperm membrane renders it vulnerable to injury during cryopreservation. Production of reactive oxygen species, which are by-products of metabolism, increases during freezing and thawing, causing damage to sperm membranes and acrosomes as well as affecting mitochondrial activity.
