1. 1. Wavelength-dependent limb darkeningin the analysis oftransit spectroscopy of exoplanets

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Alberto García Ribas; [2023]
   Keywords : ;

   Abstract : Limb darkening, an optical effect characteristic of stars, where the limb (edge) seemsto be darker than the centre of the stellar body; plays an important role in our under-standing of exoplanetary transits, as it is fundamental for developing light curve modelsthat can help to undercover extrasolar companions. To recover atmospheric featuresfrom exoplanets, a principal component analysis method is typically used. READ MORE

3. 2. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

   University essay from KTH/Materialvetenskap

   Author : Mochen Li; [2023]
   Keywords : Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

   Abstract : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. READ MORE

4. 3. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Gila van den Eijnde; [2023]
   Keywords : Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

   Abstract : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. READ MORE

5. 4. Mouthfeel Assessment of Tetra Pak Paper Straws: Exploring the Correlation between Instrumental Measurements and Sensory Evaluation

   University essay from Lunds universitet/Förpackningslogistik

   Author : Natchaya Hanprerakriengkrai; [2023]
   Keywords : mouthfeel; paper straws; correlations; instrumental measurement; sensory evaluation; Technology and Engineering;

   Abstract : The implementation of the Single-Use Plastics Directive has gained significant attention due to the detrimental impacts of plastic pollution, leading to the transition from plastic straws to paper straws for Tetra Pak’s portion-size carton packages. However, the acceptance of paper straws could be hindered by negative mouthfeel perceptions, which customers find the difficulties to accurately describe them. READ MORE

6. 5. The combination of SFDI with a mathematical model links perturbation in microcirculation to early stages of sepsis

   University essay from Linköpings universitet/Institutionen för medicinsk teknik

   Author : Caroline Korsfeldt; Sara Karajica; [2022]
   Keywords : SFDI; SFDS; mathematical modeling; sepsis;

   Abstract : The microcirculation system is crucial for the function of delivering biological markers such as oxygen and removing carbon dioxide from all the cells forming the complex ma- trix of tissue in the body. To keep up with the demands of each and every cell, there is a response from the microvasculature - resulting from for instance changes in blood flow to the tissue area. READ MORE
