    Sammanfattning :  In July 2031, a new chapter in the exploration of the Jovian system will begin with the arrival of the Jupiter Icy Moons Explorer (Juice) at Jupiter. Launched on April 14 2024 as part of ESA’s Cosmic Vision programme, the mission aims to study Jupiter and its icy Galilean moons Callisto, Europa, and Ganymede. LÄS MER

  3. 2. Evaluation of five hardwood species from Zambia to produce fuel pellets for cooking purposes : Study with a single pellet press including pellet production, post production testing and X-ray examinations

    Sammanfattning : 81% of the population in sub-Saharan Africa relies on charcoal and firewood to cover their energy needs for cooking. In Africa charcoal is usually produced by burning tree in a traditional kilns and then the food is cooked with a carbon-fired stoves indoors. LÄS MER

  4. 3. Plume-Spacecraft Interaction Analysis : Study on the Plume Effects of Hall-Effect Thrusters (HET) and High-Efficiency Multistage Plasma Thrusters (HEMPT).

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Sammanfattning : Plume-spacecraft interactions play an important role in the performance and integrity of spacecraft during their missions in space. The study encompasses a thruster’s plume simulation and its impact on spacecraft geometries to understand and predict the effects and consequences of the impingement on spacecraft surfaces, such as erosion, contamination, forces, and torques.

  5. 4. Elevernas inflytande på fritidshemmet

    Kandidat-uppsats, Högskolan i Borås/Akademin för bibliotek, information, pedagogik och IT

    Författare :Johny Gebrayel; [2023]
    Nyckelord :Authority; influence; Makt; inflytande;

    Sammanfattning : : Eleverna har inflytande över att äta så mycket de ville av det som erbjöds på frukosten i matsalen. Dessutom kunde de välja att sitta vid ett bord och äta frukost med några elever från fritidshemmet och att de hade inflytande över att kunna prata med varandra. Dock på den bestämda ytan. LÄS MER

  7. 5. Ur samma jord

    Kandidat-uppsats, KTH/Arkitektur
