  1. 1. Computational prediction of antisense oligonucleotides and siRNAs

    Författare :Alistair Chalk; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Antisense oligonucleotides; siRNAs; Artificial neural networks; Support vector machines; prediction; specificity.;

    Sammanfattning : Two popular gene knockdown methods, antisense oligonucleotides (AOs) and short interfering RNAs (siRNAs) are commonly used to selectively inhibit gene expression (gene knockdown). This is an extremely valuable tool for functional genomics, however the selection of effective molecules using either method is non trivial. LÄS MER

  3. 2. Milankovitch Cycles in Chalks, Danish North Sea, Detected by Use of Magnetic Susceptibility

    Författare :Morten G. Stage; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; magnetic susceptibility; Maastrichtian; Milankovitch cycles; North Sea; chalk;

    Sammanfattning : Subdivision of the Maastrichtian chalk from the Danish North Sea has proven to be difficult because of the homogenous composition and appearance. A high-resolution subdivision of the chalk yields new information and better understanding of the depositional environment along with the possibility of an advantageous correlation. LÄS MER

  5. 4. Low smoke halogen-free materials for wire and cable applications

    Författare :Anna Lundgren; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flame retardant; calcium carbonate; calcium silicate; Casico; polyolefin; effervescence; intumescent structure; thermal degradation; silicone elastomer;

    Sammanfattning : Fire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start a fire and/or spread one. Traditionally, materials containing halogen have been used as primary insulation in low voltage power and telecommunication cables and most cables used today therefore contain halogen. LÄS MER

  7. 5. Mechanism of a polyolefin based effervescent flame retardant material

    Författare :Anna Lundgren; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intumescent structure; flame retardant; Casico; silicone elastomer; polyolefin; effervescence; calcium carbonate;

    Sammanfattning : ABSTRACTFire safety issues are becoming increasingly important in modern society and cables are one potential fire risk since they can start and/or spread a fire. As a result of environmental and safety issues having to do with flame retardants based on halogens, much attention has lately been given to finding halogen free alternatives. LÄS MER
