   Sammanfattning : The topical issue of climate change has increasingly become important as scenarios indicate an increase of 2.5–7.8°C in the global mean temperature by the end of this century, if no greenhouse gas emissions are reduced. LÄS MER

3. 2. The reactive formation of TiSi2in the presence of refractory metals

   Författare :Aliette Mouroux; KTH; []
   Nyckelord :;

   Sammanfattning : Titanium disilicide (TiSi2) has been the favoured material for contactmetallisation in recent Si devices. The formation of TiSi2usually begins with the high resistivity C49 phaseas a result of the Ti-Si interaction at about 300-550 °Cand finishes with the low resistivity C54 phase through theC49-C54 phase transformation at about 700 °C.

4. 3. Integrated strength grading

   Författare :Mattias Brännström; Hans Joachim Blaß; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Träteknik; Wood Technology;

   Sammanfattning : This work comprises strength grading for structural timber according to European standards and prediction of grade-determining properties by various technologies and in various stages of the sawmilling process. The detection technologies applied on logs were outer shape scanning, laser scattering, x-ray scanning and resonance analysis. LÄS MER

5. 4. High-Resolution Studies of Silicide-films for Nano IC-Components

   Författare :Tobias Jarmar; Fredric Ericson; Ulf Smith; Terje Finstad; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; thin films; titaniumsilicide; nickel-germanosilicide; ternary phase diagram; textured germanosilicide; high resolution materials analysis; Materialvetenskap; Materials science; Teknisk materialvetenskap;

   Sammanfattning : The function of titanium- and nickel-silicides is to lower the series resistance and contact resistivity in gate, source and drain contacts of an integrated circuit transistor. With decreasing dimensions, the low resistivity C54 TiSi2 is not formed and stays in its high resistivity phase C49. LÄS MER

7. 5. Organic micropollutants in highway stormwater and the role of a gross pollutant trap-biofilter stormwater treatment train

   Författare :Ali Beryani; Godecke-Tobias Blecken; Maria Viklander; Katharina Tondera; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : The studies which this thesis is based on assessed the stormwater quality in a highway catchment located in Sundsvall, Sweden, and examined the performance of a gross pollutant trap (GPT)-biofilter stormwater treatment train (TT) downstream of the catchment, in terms of removal efficiency, intra-event variability, and environmental risk reduction of organic micropollutants (OMPs) for the receiving water body. Assessing the occurrence and event mean concentrations (EMCs) of all OMPs in the catchment revealed that bisphenol A (BPA), octylphenol (OP), nonylphenol (NP), five carcinogenic and four non-carcinogenic polycyclic aromatic hydrocarbons (PAHs), and C16-C40 fractions of petroleum hydrocarbons (PHCs) all potentially pose an environmental risk to freshwater (EMCs >PNEC: predicted non-effect concentration), while alkylphenolethoxylates, six low- molecular weight PAHs, and lighter fractions of PHCs (C10-C16) do not occur at problematic levels.
