    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; copolymer hydroxybenzoic acid; thermotropic liquid crystalline polymers; polyethylene terephthalate; mechanical properties; hydroxybenzoic acid;

    Sammanfattning : Fibres of thermotropic liquid crystalline polymers (LCP) and its blends containing a random coil polymer LCP have been spun at low draw ratio at different temperatures and shear rates. Their mechanical properties have been studied in detail. LÄS MER

  4. 3. A study of galaxy evolution: stacking emission lines from distant galaxies

    Författare :Jean Baptiste Jolly; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Galaxies: evolution – Galaxies: high-redshift – methods: stacking – methods: data analysis – techniques: interferometric;

    Sammanfattning : To draw up a thorough description of galaxy evolution exhaustive observations are needed, of distant but mainly of faint galaxies. Describing low mass galaxies is important to move the focus from the tip of the iceberg. LÄS MER

  5. 4. Prostate cancer : population-based screening and markers for long-term clinical outcome

    Författare :Per-Olof Lundgren; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : In 1988 and 1989 a large screening study for prostate cancer was launched in Stockholm, Sweden. At the time approximately 27 000 men between 55 and 70 years of age resided within a defined area of southern Stockholm. LÄS MER

  7. 5. Sensor Networks and Their Radio Environment : On Testbeds, Interference, and Broken Packets

    Författare :Frederik Hermans; Per Gunningberg; Edith Ngai; Andreas Terzis; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sensor networks; Testbed; Mobility; Interference classification; Packet corruption; Computer Science with specialization in Computer Communication; Datavetenskap med inriktning mot datorkommunikation;

    Sammanfattning : Sensor networks consist of small sensing devices that collaboratively fulfill a sensing task, such as monitoring the soil in an agricultural field or measuring vital signs in a marathon runner. To avoid cumbersome and expensive cabling, nodes in a sensor network are powered by batteries and communicate wirelessly. LÄS MER
