1. Increasing the diodicity of ceramic Tesla valves by exploiting the design freedom of additive manufacturing : A study in design optimizations of Tesla valves for ceramic 3D printing
University essay from Uppsala universitet/Institutionen för materialvetenskapAbstract : The work presented in this thesis was conducted at Uppsala University and at Fraunhofer IKTS, Dresden. The thesis aims to study design optimizations for increasing the diodicity and thereby performance of a Tesla valve, a type of “no moving parts” (NMP) valve, through design freedoms offered by ceramic additive manufacturing.

3. Outdoor Education and Teachers’ Subjective Well-Being : A correlational study on the well-being of Dutch primary school teachers and the use of outdoor education
University essay from Linköpings universitet/Institutionen för beteendevetenskap och lärandeAbstract : The present study among Dutch primary school teachers investigated the difference in teachers' subjective well-being (SWB) between teachers that used outdoor education (OE) and their peers. The influence of the duration and frequency of outdoor lessons has also been explored. A similar study showed that outdoor educators had a higher SWB. READ MORE

4. An Evaluation Study of Leak Testing Technologies for Watertight Plate Heat Exchangers : Fast and sustainable leak testing technology for high energy efficiency products
University essay from Blekinge Tekniska Högskola/Institutionen för matematik och naturvetenskapAbstract : Background: One part of manufacturing a Plate Heat Exchanger (PHE) is to leak test them before delivery. Today, helium is used extensively in leak testing. How-ever, it is unsustainable to use helium in leak testing, because of its non-renewability and therefore becoming more and more expensive. Also, this technology is relatively complex. READ MORE

5. Parametric investigation of a theoretical organic rankine cycle
University essay from Mälardalens universitet/Akademin för ekonomi, samhälle och teknikAbstract : The energy resource waste heat or low-grade thermal energy is available in vast quantities. Tapping into this resource and converting it to electrical energy would not only reduce energy waste but also has the potential to eliminate greenhouse gas emissions. READ MORE
