  1. 16. Smart Hydroponics : Conceptual Design of Hydroponic Plant System for Home Environment

    University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Author : Erik Földhazy; [2018]
    Keywords : Industrial Design Engineering; User Experience; Sustainability; Product Design; Human- Centered Design; Hydroponics; Teknisk Design; Användarupplevelse; Hållbarhet; Produktdesign; Human-Centered Design; Hydroponik;

    Abstract : Hydroponics is a method of cultivating plants without the use of soil. Soil acts as a growth medium which gives plants stability, provides nutrients and allows roots to be kept wet without drowning. In hydroponics the soil’s functions are replaced by synthesized methods. Stability comes from a substrate (i. READ MORE

  3. 17. The cow eye : function and effect of light on milk yield

    University essay from SLU/Dept. of Animal Nutrition and Management

    Author : Hanna Tiilikainen; [2018]
    Keywords : cow-eye; light; photoperiod; milk-yield; prolactin; melatonin;

    Abstract : The purpose of this review was to study the cow’s eye physiology, focusing on how light affects the cow’s milk yield. It has been shown in studies that more hours of light per day (16 hours of light a day, as opposed to about 9-12 hours of light a day), increases milk yield for dairy cows. READ MORE

  4. 18. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik
