1. 1. Exocomets in the β Pictoris system

   University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Author : Klaudia Jaworska; [2024]
   Keywords : Physics and Astronomy;

   Abstract : Comets have been a source of fascination throughout the history of man. In recent years, advances in technology have opened up for the study of extrasolar objects, among them exocomets. The first exocomets were observed in the β Pictoris system almost 50 years ago and the system has been of interest ever since. READ MORE

3. 2. 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 naturvetenskap

   Author : Fritjof Nilsson; Yanjun Peng; [2023]
   Keywords : Leak rate; Optimization; Pressure Decay; Vacuum Technology; Volume; Läckhastighet; Optimering; Tryckfall; Vakuum Teknologi; Volym;

   Abstract : 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

4. 3. Att motverka luftemboli vid transfusion av blodprodukter : en pilotstudie av produkten AirVault

   University essay from SLU/Dept. of Clinical Sciences

   Author : Amanda Nordgren; Marie-Louise Sund; [2023]
   Keywords : AirVault; blodtransfusion; FFP; hund; luftbildning; luftemboli; pRBC;

   Abstract : En blodtransfusion kan vara en livsnödvändig behandling vid akut blodförlust, anemi och vid vissa blödarsjukdomar. Att ge blodtransfusioner är dock inte helt riskfritt, en potentiell fara är att det kan bildas luftbubblor i blodet inom aggregatslangarna enligt Henrys lag. READ MORE

5. 4. Improving the understanding of photoelectron currents on Solar Orbiter : Utilizing theory and empirical measurements

   University essay from Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Melker Marminge; [2023]
   Keywords : Solar Orbiter; Photoelectric Currents; Photoelectric Effect; Thermal Bending; Outgassing; Thermionic Emission; Numerical Approximation; Physical Modeling;

   Abstract : Spacecraft experience electric currents on conductive materials exposed to sunlight, which introduces noise in scientific data. These currents are mainly due to the photoelectric effect and should therefore be proportional to the inverse square heliocentric distance. READ MORE

6. 5. A kinetic perspective of electron trapping near a weakly outgassing comet

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Chaitanya Prasad Sishtla; [2019]
   Keywords : ;

   Abstract : The European Space Agency’s Rosetta spacecraft followed the comet 67P/Churyumov-Gerasimenko from August 2014 to September 2016, providingobservations of the comet ionosphere at varying heliocentric distances. Measurementsfrom the Rosetta mission have shown a multitude of non-thermalelectron distributions in the cometary environment, challenging the previouslyassumed origin and plasma interaction mechanisms near a cometary nucleus.
