  1. 36. Bax and oxidized phospholipids - a deadly complex : Apoptotic protein-lipid assemblies studied by MAS NMR spectroscopy

    Författare :Artur Dingeldein; Gerhard Gröbner; Mikael Elofsson; Tobias Sparrman; Daniel Topgaard; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NMR spectroscopy; mitochondrial membranes; apoptosis; membrane dynamics and organization; Bcl-2 family proteins; Bax protein; biokemi; Biochemistry;

    Sammanfattning : Mitochondria are renowned for their vital role as cellular powerhouses because they provide ATP via cellular respiration. Additionally, these organelles also play an important role in other physiological processes, such as apoptosis. LÄS MER

  3. 37. Medborgarskap efter nationalstaten? : Ett konstruktivt förslag

    Författare :Christian Fernández; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Proposal; Constructive analysis; Normative analysis; Residence; Neo-republicanism; European Union; Multiculturalism; Cosmopolitanism; Trans-naitonalism; Citizenship; Post-national citizenship; Political and administrative sciences; Statsvetenskap; förvaltningskunskap;

    Sammanfattning : This thesis is an attempt to formulate a constructive proposal for the ongoing establishment of a post-national European citizenship in the European Union. To the extent that the proposal is post-national, the ambition is to re-conceptualise the idea and ideal of citizenship in a new historical setting. LÄS MER

  4. 38. Industrial development of car disassembly - ergonomics and system performance

    Författare :Karolina Kazmierczak; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physical workloads; production systems; muskelsystem; reumatologi; rheumatology locomotion; Skelett; muscle system; Skeleton; flow and human simulations; video-task analysis; rationalizations; car disassembly; musculoskeletal disorders; Technological sciences; Teknik;

    Sammanfattning : A new EU directive on used vehicles has recently been introduced. It demands that for every scrapped car, at least 85% by weight must be recycled by the year 2006 and 95% by 2015. The current level is about 80%. The car disassembly industry was chosen as the study object of this thesis. LÄS MER

  5. 39. Apoptosis induced by a human milk protein complex. Cellular and structural studies in tumour cells and bacteria

    Författare :Anders Håkansson; immunologi och glykobiologi - MIG Avdelningen för mikrobiologi; []

    Sammanfattning : Human milk contains a vast array of bioactive molecules, with nutritional and protective functions. This thesis describes the effects of a human milk protein complex, MAL, on tumour cells and bacteria. During our studies on the anti-adhesive properties of human milk we observed that a milk fraction killed tumour cells. LÄS MER

  7. 40. Towards understanding breakage and flow in sublevel caving (SLC) : Development of new measurement techniques and results from full-scale tests

    Författare :Matthias Wimmer; Pekka Särkkä; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Sammanfattning : Blast function, fragmentation and gravity flow are core elements for sublevel caving (SLC). For the ore recovery to be as high and the waste rock dilution as low as possible all three elements have to work as planned. LÄS MER
