1. The visibility of stellar transients in the Galactic Centre
University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/AstrofysikAbstract : A semi-analytical simulation was developed to evaluate the K-band magnitudes of Red Giants [0.96 - 1.02 M⊙] orbiting the supermassive black hole in the galactic centre. The model assumed star formation between 10-12 Gyrs ago and by following the IMF and applying a random age condition, a stellar population was created. READ MORE

2. N-body simulations of exoplanets and their moons
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. READ MORE

3. Direct solar dryer
University essay from Lunds universitet/Institutionen för energivetenskaperAbstract : The study presents the design, construction, and performance evaluation of a direct solar dryer with a focus on enhancing the post-harvest preservation of fruits. The increasing demand for the dry fruits in both the local and export markets demand effective and environmentally friendly drying methods. READ MORE

4. The quest for a classical bulge - a study of kinematics, abundances, and ages using microlensed dwarf stars and Gaia
University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionenAbstract : Context: We present an kinematical analysis of 90 F and G type dwarf, turn-off, and subgiant stars in the Galactic bulge. These stars were observed with high-resolution spectrographs during gravitational microlensing events This allowed for their ages, abundances, and radial velocities to be ascertained while they were significantly brighter.

5. The Impact of Trade Openness on the Gender Wage Gap in Urban China, 2002-2013
University essay from Lunds universitet/Ekonomisk-historiska institutionenAbstract : This paper examines the impact of trade openness on the gender wage gap in urban China after China's accession to the WTO in 2001. Using data from the 2002 and 2013 China Household Income Project (CHIP), this paper uses OLS regression and instrumental variable regression, to analyze the relationship between trade openness and the gender wage gap.
