  1. 1. Advanced Characterization of Exoplanet Host Stars

    University essay from Uppsala universitet/Observationell astrofysik

    Author : Khaled Al Moulla; [2020]
    Keywords : stars: exoplanet hosts - fundamental parameters - spectroscopy: HARPS - SME; stjärnor: exoplanetvärdar - fundamentala parametrar - spektroskopi: HARPS - SME;

    Abstract : The spectroscopic determination of stellar properties is important for subsequent studies of exoplanet atmospheres. In this thesis, HARPS data for 6 exoplanet-hosting, late-type stars is processed to achieve an average signal-to-noise ratio of ~105. READ MORE

  2. 2. Effect of temperature on plant growth and yield in everbearing strawberry Fragaria x ananassa, cv. Florentina

    University essay from SLU/Department of Biosystems and Technology (from 130101)

    Author : Denis Butare; [2020]
    Keywords : strawberry; ever-bearing; temperature; flower mapping; photoperiod; flowering; plant development; yield;

    Abstract : Strawberry (Fragaria x ananassa Duch.) growth and yield are under genetic control and regulated by environmental factors such as temperature and photoperiod. The major objective of this study was to determine the effects of temperature under short-day treatment on plant development and flowering in the ever-bearing strawberry cv. READ MORE

  3. 3. Chemical recycling of cotton-based waste textiles by sulfuric acid hydrolysis

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Edvin Ruuth; [2020]
    Keywords : recycling; hydrolysis; cotton; waste textiles; sulfuric acid; glucose; chemical engineering; kemiteknik; Technology and Engineering;

    Abstract : Large amounts of waste textiles are produced annually, of which only a small fraction is recycled currently. The purpose of this study was to develop a method to recycle cotton-based waste textiles chemically that can be coupled to the production of biofuels or green chemicals. READ MORE

  4. 4. The Quantum Hall Effect

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Conrad Grälls; [2020]
    Keywords : quantum hall effect; QHE; fractional quantum hall effect; FQHE; hall effect;

    Abstract : The quantum Hall effect occurs when a conductor carrying a current is placed in a perpendicular magnetic field. If certain conditions are met, such as strong magnetic field and low temperature, the resistivity becomes quantised, taking values of integer or fractional multiples of h/e2. READ MORE

  5. 5. Beteendeeffekter av antidepressivt läkemedel på abborre (Perca fluviatilis) : socialt och aktivt beteende undersökts genom att kombinera behandlingar med oxazepam, temperatur och predationstryck

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Oskar Karlsson; Svante Knutsen; [2020]
    Keywords : antidepressiva läkemedel; oxazepam; abborre;

    Abstract : Användandet av antidepressiva och ångestdämpande läkemedel, som ex. oxazepam, ökar i samhället vilket kan leda till höga halter i våra vattendrag. Tidigare studier har visat att abborrar som blir utsatta för miljörelevanta koncentrationer av oxazepam ändrar sitt beteende. READ MORE
