1. 1. Characterisation of Non-metallic Inclusions in Special Steels using Electrolytic Extraction

   Master-uppsats, KTH/Materialvetenskap

   Författare :Josefin Mvele Svensson; [2024]
   Nyckelord :Non-metallic inclusions; electrolytic extraction; SEM; Icke-metalliska inneslutningar; elektrolytisk extraktion; SEM;

   Sammanfattning : When producing high strength special steels strict requirements are in place to assure the quality of the final product, both in terms of harmful elements and  the  content  of  non-metallic  inclusions  (NMI).  Achieving  cleanliness  is a  gradual  process  where all  the  steps  of  the  production  process  are  inter- connected, meaning that it is crucial to know the influence of each step in order to assure the contents of the final product.

3. 2. Global Framework Agreements - A solution to fill the vacuum of global labour law?

   Kandidat-uppsats, Lunds universitet/Institutionen för handelsrätt

   Författare :Anna Larsson; Hanna Engblom; [2024]
   Nyckelord :Globalisation; Global framework agreements; International framework agreements; Multinational enterprises; Global union federations; Global supply chain; Law and Political Science;

   Sammanfattning : The phenomenon of global framework agreements has emerged through the difficulties of regulating the global labour market where the multinational enterprises' operations have been driven by an economic agenda and profit. The challenges of creating transnational legislation have brought social actors, such as the United Nations and the International Labour Organisation, to initiate self-regulatory instruments.

4. 3. Israel, Russia and the US: A Strange Triangular Relationship : An analysis of an unexpected alliance and its rationality

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för samhällsstudier (SS)

   Författare :Alfred Lovnér; [2024]
   Nyckelord :International Relations; Political Influence; Security; Peace; Development;

   Sammanfattning : The relationship between Israel and the US, as well as Israel and Russia are well documented, as it serves as a key aspect within the struggle for power and influence within the Middle East. However much research has been made on the topic, few have analysed how the relationship between Israel and the two others have affected the three, creating what could only be viewed as a blindspot within scholarship on the topic, as the relationships did not start in, nor are maintained within a vacuum.

5. 4. ”Skoba [dammsug] igen, en gång till!” : Barns interaktioner med dammsugaren som ett tekniskt system i en undervisningssituation

   Uppsats för yrkesexamina på grundnivå, Karlstads universitet/Institutionen för pedagogiska studier (from 2013)

   Författare :Joline Lövgren Röös; [2024]
   Nyckelord :Design-based study; teaching activity; technical system; the youngest chil-dren; vacuum cleaner; Dammsugaren; designbaserad studie; de yngsta barnen; tekniska system; undervisningsaktivitet;

   Sammanfattning : Teknik framställs som ett viktigt ämne i förskolans läroplan. Samtidigt utrycker många förskolelärare en brist på kunskap om att undervisa i tek-nikämnet. I studien ska jag ge ett exempel på en undervisningsaktivitet. LÄS MER

7. 5. The active phase of Pt(110) during catalytic CO oxidation

   Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

   Författare :Hira Qazilbash; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. LÄS MER
