2. A study of the stability of vitamin 25[OH]D2 and 25[OH]D3
University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)Abstract : During the industrialization of the 19th century the negative health effects of vitamin D was discovered as children in the cities developed osteomalacia or more commonly known as rickets caused by vitamin D deficiency. Vitamin D is produced in the skin from 7-dehydrocholesterol during sun-exposure and enhances intestinal phosphor and calcium absorption thus enhancing the bone remodeling process. READ MORE

3. A Quadrature Frequency Generation Chain for Direct-conversion Phased-array 5G Transceivers
University essay from Lunds universitet/Institutionen för elektro- och informationsteknikAbstract : The 5th generation (5G) has recently specified a new spectrum range, FR2- 5G New Radio (5G-NR), to provide higher spectral efficiency and channel capacity for ubiquitous cellular connectivity where the user ends can be in various types such as picocell stations, sensor nodes, cloud servers, hand-held devices, and so on. Due to the advantage of phased array antennas in performing beam-forming, and improving SNR at higher spectra, multi-antenna systems have gained an inevitable role in developing such radios.

4. Techno-economic Study of Hydrogen as a Heavy-duty Truck Fuel : A Case Study on the Transport Corridor Oslo – Trondheim
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Norway has already an almost emission-free power production and its sales of zero-emission light-duty vehicles surpassed 30% in 2018; a natural next challenge is to identify ways to reduce emissions of heavyduty vehicles. In this work the possibilities to deploy Fuel Cell Electric Trucks (FCET) on the route Oslo-Trondheim are analyzed by doing a techno-economic analysis. READ MORE

5. LIGHT AS A TOOL TO STRUCTURE URBAN PLANNING : A Socially-Oriented Approach
University essay from KTH/LjusdesignAbstract : How can light positively influence and encourage pedestrians’ engagement and interaction with the urban environments at night? In this Master Thesis, I questioned how to develop nighttime urban planning from a socially-oriented approach. In order to answer this question, I studied different evidence such as two publications, three lighting designers’ and a lighting studio’ approach; three case studies analyses, two of them located in Colombia (Cartagena and Medellín) and one in Sweden (Stockholm);and my own qualitative observation and quantitative measurements studied between April and May at Norrmalmstorg and Biblioteksgatan in Stockholm, Sweden.
