  2. 2. Maturation of Clay Seals in Deep Bore Holes for Disposal of Radioactive waste : Theory and Experiments

    Författare :Ting Yang; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high-level radioactive waste; HLW; very deep borehole; VDH; disposal; saturation degree; water transport; maturation; model; shear strength; hydraulic conductivity; swelling pressure; homogenization; Geoteknik; Soil Mechanics;

    Sammanfattning : KBS-3 and very deep borehole (VDH) concepts are two major types of long-term geologicaldisposal methods for high-level radioactive waste (HLW) isolating from the biosphere. TheKBS-3V concept for isolating the HLW at the depth of 400-500 m, is the officially proposedoption in Sweden and has been the subject of considerable research in the past few decades,while the VDH concept was considered as an option in the 1950s but later became discouragedbecause of insufficient experience in drilling technology.

  3. 3. The object markers ba and jiang in modern literary Chinese

    Författare :Wai-Ling Ragvald; Kinesiska; []
    Nyckelord :HUMANIORA; HUMANITIES; literary Chinese; South-East China; object marker; jiang; ba; instrumental; disposal construction; pattern; action verbs; style; euphony; four character phrase; Mandarin; tradition; Cantonese; Minnan dialect; Hakka; East and Central China; North China; Taiwan; Hong Kong;

    Sammanfattning : Modern standard written Chinese has two common object markers, 把 ba and 将 jiang, both of which mark a direct object preceding the verb. Both markers appear to have been widely used in the spoken language of the Tang dynasty but the actual distribution is not entirely clear. LÄS MER

  4. 4. Hydro-mechanical properties of a water unsaturated sodium bentonite. Laboratory study and theoretical interpretation

    Författare :Ann Dueck; Institutioner vid LTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materiallära; Anläggningsteknik; Material technology; Construction technology; materialteknik;

    Sammanfattning : Highly compacted bentonite has been proposed as the buffer material in the Swedish concept for the disposal of nuclear waste. To increase the knowledge of the hydro-mechanical behaviour of unsaturated swelling bentonite a series of laboratory experiments was carried out. LÄS MER

  5. 5. Life-Cycle Energy and Carbon Implications of Wood-Based Products and Construction

    Författare :Roger Sathre; Leif Gustavsson; Birger Solberg; Mittuniversitetet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; forest products; climate change mitigation; carbon balance; energy; life cycle; wood; land use; Environmental engineering; Miljöteknik;

    Sammanfattning : Forests can be an important element of an overall strategy to limit the atmospheric concentration of carbon dioxide (CO2) that contributes to climate change. As an integral part of the global carbon cycle, forests remove CO2 from the atmosphere as they grow, and accumulate carbon in tree biomass. LÄS MER
