  1. 1. Additive manufacturing of lunar regolith simulant using direct ink writing

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Billy Grundström; [2020]
    Nyckelord :3D printing; additive manufacturing; lunar regolith simulant; european space agency; ESA; in situ resource utilisation; ISRU; direct ink writing; sintering;

    Sammanfattning : In this work, the use of a lunar regolith simulant as feedstock for the direct ink writing additive manufacturing process is explored, the purpose of which is to enable future lunar in-situ resource utilisation. The feasibility of this approach is demonstrated in a laboratory setting by manufacturing objects with different geometries using methyl cellulose or sodium alginate as binding agents and water as liquid phase together with the lunar regolith simulant EAC-1A to create a viscous, printable ‘ink’ that is used in combination with a custom three-axis gantry system to produce green bodies for subsequent sintering.

  3. 2. British, medical practitioners’ perspectives on dysentery 1740-1800

    Master-uppsats, Uppsala universitet/Historiska institutionen

    Författare :Filip Hellström; [2020]
    Nyckelord :British; Medical practitioners; Dysentery; Physicians; Surgeons; Early modern period; Medical knowledge.;

    Sammanfattning : This master thesis aims to show how a qualitative approach to early modern medical practitioners’ perspectives can provide a basis for a better understanding of the disease of dysentery. The focus is on: 1) How the disease of dysentery was described and how the challenge of dysentery was perceived. LÄS MER

  4. 3. Lunar Light House

    Master-uppsats, Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Monika Lipinska; [2018]
    Nyckelord :architecture; space; space architecture; moon; lunar; light house; cellulose; nano-cellulose; moon base; lunar outpost; Arts and Architecture;

    Sammanfattning : The Lunar Light House project was developed to provide a novel system of protection against cosmic radiation specifically for a surface Lunar base. It’s main target was to find a technical solution which would allow for more freedom in shaping the base structure and also potentially for introducing natural sun light. LÄS MER

  5. 4. Development of a Lunar Regolith Thermal Energy Storage Model for a Lunar Outpost

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Aaron Valle Lozano; [2016]
    Nyckelord :Thermal engineering; thermoelectrics; thermal; lunar base; simulations; exploration; space exploration; energy storage;

    Sammanfattning : The Moon has always been an important milestone in space exploration. After the Apollo landings, it is logical to think that the next step should be a permanent habitation module, which would serve as a testing ground for more ambitious projects to Mars and beyond. LÄS MER

  7. 5. Effects of high-altitude trekking on body composition

    Kandidat-uppsats, Mittuniversitetet/Avdelningen för hälsovetenskap

    Författare :Ulrika Frisk; [2014]
    Nyckelord :Extreme environment; fat-free mass; hypoxia; iDXA; mountaineering; weight loss;

    Sammanfattning : Sojourns at high altitude are often accompanied by weight loss and changes in body composition. The aim was to study body composition before and after 40 days high-altitude exposure. LÄS MER
