  1. 1. Investigation of Antenna Radomes in Low Earth Orbits

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Mathias Manohar Gren; [2023]
    Keywords : Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Abstract : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  3. 2. Optical properties of water absorbing textiles for camouflage

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Eveline Örtenberg; [2023]
    Keywords : Camouflage; SWIR; Water; Nanocellulose; CNF; Textiles;

    Abstract : Background matching, a form of camouflage, involves species developing patterns and coloration that closely resemble their environment. Humans have utilized camouflage and background matching, particularly in military applications, to reduce detectable characteristics, known as signatures. READ MORE

  4. 3. Development and Evaluation of an Enzyme-Based Sunscreen

    University essay from Lunds universitet/Bioteknik; Lunds universitet/Bioteknik (master)

    Author : Karolina Eriksson Torfgård; [2023]
    Keywords : Enzyme activity; UV-filter; Protease; Biotechnology; Technology and Engineering;

    Abstract : Ultraviolet radiation (UVR), specifically of UVA and UVB, has been associated with the development of both photoaging and photo-carcinogenesis, potentially leading to cancer. The use of sun protection in the form of UV filters is known to minimize these damages. READ MORE

  5. 4. Contribution to Sustainable Water Management in oligotrophic mountainous rivers : Sunlight induced inactivation of Escherichia coli under the influence of physicochemical parameters water-color and water depth

    University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Author : Béla efternamn:Szépfalusi Student 1; [2022]
    Keywords : bacterial inactivation; E. coli; UV-radiation; water color; water depth; sustainable water management;

    Abstract : Water is essential for life on earth. Human society is challenged to sustain sufficient water quantity of good quality. This objective is reflected in sustainable development goal 6, “clean water and sanitation”. READ MORE

  6. 5. Targeted and non-targeted approaches to ImprUV the nutritional profile of greenhouse crops

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Hanna Forsman; [2022]
    Keywords : ;

    Abstract : This work was made to discover if greenhouse crops, particularly broccoli and Chinese cabbage, can change their metabolism and therefore their nutritional profile depending on what ultraviolet radiation (UV) they were exposed during growth. This is important since the world’s population increases and therefore, we need to be able to produce foods with increased nutritional quality. READ MORE
