   Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Författare :Kenny Andersson; [2023]
   Nyckelord :space debris; NASA standard breakup model; satellite fragmentations; satellite fragmentation modelling; space surveillance and tracking; ESA MASTER; collision risk; risk assessment; space situational awareness; rymdskrot; NASA standard breakup model; satellitfragmentering; modellering av satellitfragmentering; inmätning och övervakning av rymdobjekt; ESA MASTER; kollisionsrisk; riskbedömning; rymdlägesbild;

   Sammanfattning : The increasing reliance on space infrastructure and its rapid expansion necessitate the development and enhancement of tools for space debris and fragmentation research. Accurate prediction of the risks associated with satellite fragmentation requires comprehensive understanding of the dynamics involved. LÄS MER

3. 2. Jet fragmentation in shaped charges

   Master-uppsats, KTH/Matematik (Avd.)

   Författare :Joakim Ericson; [2022]
   Nyckelord :Shaped charges; numerical simulation; jet fragmentation; Riktad sprängverkan; numerisk simulering; strål-fragmentering;

   Sammanfattning : This master thesis treats the numerical simulation of shaped charge jets and its fragmentation process. Shaped charges is a method to concentrate the effect of an explosive charge and penetrate deeply into a target due to a the formation of a jet with great penetration capabilities. LÄS MER

4. 3. Mobilising the Lebanese Diaspora in Times of Political Turmoil at “Home” : Investigating online engagement practices and the roles of the alternative online medium Thawra Chronicles in the context of the Lebanese Revolution 2019

   Master-uppsats, Lunds universitet/Medie- och kommunikationsvetenskap; Lunds universitet/Institutionen för kommunikation och medier

   Författare :Victoria Becker; [2021]
   Nyckelord :digital diaspora; Lebanese diaspora; digital activism; awareness activism; alternative media; Lebanese Revolution 2019; Social Sciences;

   Sammanfattning : This research focuses on the contemporary case study of the Thawra Chronicles, founded by three London-based members of the Lebanese diaspora in the wake of the Lebanese Revolution in early October 2019 to support the social movement from afar, targeting non-Lebanese individuals as well as Lebanese within and beyond its borders. Thawra Chronicles is a multifaceted, independent alternative online outlet aiming at commemorating the revolution, by providing information, curating art as well as serving as a space of participation through the upload of user-generated content and pledges.

5. 4. Comet assay: Monitoring time-dependent DNA-fragmentation in two different types of cells, optimizing Flash-comet method for pig sperm analysis

   Master-uppsats, Uppsala universitet/Institutionen för farmaceutisk biovetenskap

   Författare :Ewelina Rozwadowska; [2020]
   Nyckelord :Comet assay; Flash-comet; cell survival curves; TK6-cells; pig sperm;

   Sammanfattning : DNA-damage, caused by different factors such as oxidative stress in cells, is common in living organisms. The damage includes DNA-fragmentation, such as single- and double strands breaks. LÄS MER

7. 5. The devil in disguise : seeking political opportunity through Brexit to claim 'rights to the city' in London

   Master-uppsats, Lunds universitet/LUCSUS

   Författare :Leonard D'Crus; [2018]
   Nyckelord :Brexit; political opportunity; ‘Rights to the city’; community-led housing; Scenario analysis; London; sustainability science; Social Sciences;

   Sammanfattning : There has long been a crisis of housing affordability in London, which the government and private sector are failing to address. On top of the socio-economic challenges brought about by this, London’s current and new stock of housing are not built to the necessary environmental standards to achieve legally binding environmental targets.
