1. 1. 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

3. 2. A comparison of binaural recordings performed in six different room configurations

   University essay from Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

   Author : Denice Perkhed; [2021]
   Keywords : Binaural recordings; absorbtion coefficient; reverberation time; anechoic chamber; listening test; Psychoacoustics; Technology and Engineering;

   Abstract : Children in Swedish preschools are exposed to high noise levels that can cause hearing damage or voice related problems among both teachers and students, this since they have to raise their voice in order to make themselves heard in a noisy environment. Because of this it is of interest to be able to predict the sound environment in preschools. READ MORE

4. 3. Verification of HARMONIE-AROME, ECMWF-IFS and WRF: Visibility and Cloud Base Height

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Elin Kindlundh; [2020]
   Keywords : HARMONIE-AROME; ECMWF-IFS; WRF; verification; visibility; cloud base height; HARMONIE-AROME; ECMWF-IFS; WRF; verifikation; sikt; molnbashöjd;

   Abstract : Visibility and cloud base height are two important parameters within aviation meteorology and verification of operational numerical weather prediction (NWP) models with regard to these two parameters is therefore important. Visibility is often parameterized through an extinction coefficient, which is dependent on for example liquid or ice water content, however it also depends on the humidity, precipitation intensity and particle concentration.

5. 4. Magnesiumstatus hos mjölkkor : en fältstudie

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

   Author : Elin Briland; Cecilia Kronqvist; [2006]
   Keywords : magnesium; kalium; mjölkko; fältstudie;

   Abstract : Magnesium is an essential mineral that is important for several physiologic and biochemical processes in the body. Deficiency of magnesium is mainly associated with grass tetany, but can also appear in cows during the indoor period. Since long it is known that potassium has a negative effect on the absorption of magnesium. READ MORE
