    Nyckelord :bonding silicone; corona surface treater; SiO2 coating; thermoplastic substrate; PVD temperature; PDMS membrane; spin-coating; thickness measurements; microfluidic systems; bonding PDMS; silicon dioxide coating; spin-cast; silicone membrane; PDMS; polydimethylsiloxane; poly dimethylsiloxane ; silicon dioxide PVD; SiO2 PVD; silicon dioxide evaporation; SiO2 evaporation; thickness of a thin film; silicon dioxide deposition; SiO2 deposition; adhesion testing; cycloolefincopolymer; cycloolefinpolymer; cyclic olefin copolymer; cyclic olefin polymer; COC; COP; plasma surface treater; surface activator; surface oxidizer;

    Sammanfattning : A spin-cast silicone membrane has been successfully bonded between two injection-molded microstructured plastic discs. This sandwich structure creates a useful platform for mass production of microfluidic systems, provided that the bonds are leakproof. LÄS MER

  2. 2. Plant-pollinator networks in three habitats on a baltic island

    Kandidat-uppsats, Högskolan på Gotland/Institutionen för kultur, energi och miljö

    Författare :Jakob Wallin; [2011]
    Nyckelord :pollination; network; ecology; habitats; generalist; specialist; Gotska Sandön; Gotland; biodiversity; ecosystem service;

    Sammanfattning : Plant-pollinator networks have shown to be highly dynamic systems as species and interactions change in time and space. Few studies have incorporated several habitats in their network. In this work I investigate interacting plant and pollinator communities of three adjacent habitats at Gotska Sandön, an island in the Baltic Sea. LÄS MER

  3. 3. Koncernbidragets hantering ur ett ABL-perspektiv: - En analys av det vedertagna tillvägagångssättet

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Jakob Mörndal; Jacob Wallin; [2008]
    Nyckelord :Law; Taxation; Group contribution; Swedish Companies Act;

    Sammanfattning : The use of group contribution between consolidated firms is a common phenomenon in Sweden where taxation is not based on the return on the consolidated level but on the return on the individual firms. However, the process of handling the group contribution does not work without problems. LÄS MER

  4. 4. Simulering av hydrauliska dämpare i borrslagverk

    Magister-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling; Linköpings universitet/Institutionen för ekonomisk och industriell utveckling

    Författare :Daniel Gustavsson; Jakob Wallin; [2008]
    Nyckelord :rock; percussive; damper; hydraulic; atlas copco; rockdrill; hydraulisk; atlas copco; bergborrning; slagverk; dämpare;

    Sammanfattning : This master thesis consists of the creation of shock absorber models for percussive rock drills. A model of the rock was also developed. These models were connected to existing models of the rock drill to create a complete simulation of the rock drilling process. LÄS MER
