  1. 21. Accessory factors for ribosomal assembly

    Författare :Mattias Lövgren; Mikael Wikström; Dan Andersson; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; RimM; RbfA; RlmB; ribosomal assembly; rRNA processing; Molekylärbiologi; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : The assembly of ribosomal RNA (rRNA) and ribosomal proteins (r-proteins) into ribosomal subunits (30S and 50S) is a complex process. Transcription of rRNA requires antitermination proteins and the primary transcripts are processed by ribonucleases. LÄS MER

  3. 22. Connections for Timber-Framed Structures - Assembly Properties and Structural Behaviour

    Författare :Dan Engström; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frames; nails; connections; structures; interaction; glue; assembly; timber; economy; semi-rigidity; adhesive; joints; splices;

    Sammanfattning : By tradition, the design and development of connections has focused on the optimization of strength and stiffness. The subject of this thesis is the interaction between the assembly and structural properties of connections for timber-framed structures. LÄS MER

  4. 23. Supervisors' role in manual assembly

    Författare :Anna Grzelec; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; assembly line; first-line management; motivation; supervisor;

    Sammanfattning : There are many different ways in which to analyze an organization when striving to achieve better performance. One such way is through analyzing the supervisors in the organization. The supervisor is the first management level, and is in charge of the production personnel, i.e. LÄS MER

  5. 24. Electro-Interfacial Composition Control by Ionic Liquid Technology : Nanostructure, Self-Assembly, and Friction

    Författare :Sichao Li; Mark W. Rutland; Sergei Glavatskih; Nicholas Spencer; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ionic liquids; electrical double layer; self-assembly; electro-interfacial structure; tribotronics; supercapacitors; friction; lubrication; Jonvätskor; elektriskt dubbelskikt; självassociering; gränsskiktselektrostruktur; tribotronik; superkondensatorer; friktion; smörjning; Kemi; Chemistry;

    Sammanfattning : Given the potential of ionic liquids (ILs) for batteries, supercapacitors and advanced lubricants, it is crucial to understand how electric fields affect the interfacial behaviour in IL-solvent systems and the intricate relationship between nanostructure and tribotronic properties. This thesis investigates the structural and compositional changes of ILs with different solvents at electrified interfaces. LÄS MER

  7. 25. Individualizing assembly processes for geometric quality improvement

    Författare :Abolfazl Rezaei Aderiani; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective Assembly; Individualization of production; Locator Adjustments; sheet metal assembly processes; Variation Simulations; Geometry Assurance;

    Sammanfattning : Dimensional deviations are a consequence of the mass production of parts. These deviations can be controlled by tightening production tolerances. However, this solution is not always desired because it usually increases production costs. LÄS MER
