5. 4. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

   University essay from Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

   Author : Viktor Sparrman; [2022]
   Keywords : Plasma; Inertial confinement fusion; comet; plasma expansion; Vlasov-Poisson; integral invariants; ergodicity;

   Abstract : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. READ MORE

6. 5. Skadebild och fördelning av törskate på träd- och beståndsnivå hos tallungskog

   University essay from SLU/Dept. of Forest Ecology and Management

   Author : Moa Kinnunen; Björn Jönsson; [2022]
   Keywords : Törskate; Törskaterost; Svampskador; Rostsvamp; Multiskadad ungskog; Skadebild av törskate; Cronartium pini; Cronartium flaccidum; Peridermum pini; Resin-top disease; Rust fungi; Scots pine bister rust; Two-needle pine stem rust; Pine rust;

   Abstract : Törskate är ett alltmer uppmärksammat problem i framförallt Sveriges norra delar, där 12 till 15 % av de naturliga avgångarna av tall anses orsakade av svampen. Detta motsvarar en produktionsförlust på ca 350 000 kubikmeter talltimmer årligen. READ MORE
