1. 1. Feasibility study of soil washing to remediate mercury contaminated soil

   Författare :Jingying Xu; Bo Lind; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; soil remediation; pH-dependentdissolution; organic matter; mobilisation; Waste Science and Technology; Avfallsteknik;

   Sammanfattning : Mercury (Hg) cannot be degraded. Therefore only two principal processes are available for the treatment of Hg-contaminated soil: (1) the separation of Hg from the soil or (2) the stabilisation of Hg within the soil. Prior to selecting a suitable treatment technique, it is necessary to have an understanding of Hg behaviour in contaminated soil, i.e. LÄS MER

3. 2. Exhaust Heat Utilisation and Losses in Internal Combustion Engines with Focus on the Gas Exchange System

   Författare :Habib Aghaali; Hans-Erik Ångström; Carlos Guardiola; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; heat transfer; heat loss; exhaust heat utilisation; waste heat recovery; turbocompound; divided exhaust period; internal combustion engine; gas exchange; pumping loss; variable valve timing; WHR; DEP; Turbo; värmeöverföring; värmeförluster; avgasvärme utnyttjande; förluster vid värmeåtervinning; turbocompound; delad avgasperiod; förbränningsmotor; gasväxling; pumpningsförlust; variabla ventiltider; WHR; DEP; Vehicle and Maritime Engineering; Farkostteknik; Energy Technology; Energiteknik;

   Sammanfattning : Exhaust gas energy recovery should be considered in improving fuel economy of internal combustion engines. A large portion of fuel energy is wasted through the exhaust of internal combustion engines. Turbocharger and turbocompound can, however, recover part of this wasted heat. LÄS MER

4. 3. Structural and Functional Studies of the Density Enhanced Receptor-like Protein Tyrosine Phosphatase DEP-1

   Författare :Maria Sörby; Jeroen Hertog; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Oncology; Onkologi; Oncology; Onkologi; molekylär cellbiologi; Molecular Cellbiology;

   Sammanfattning : Tyrosine phosphorylation is a central mechanism in cellular signalling leading to proliferation, migration or differentiation. Protein tyrosine phosphorylation is regulated by the coordinated actions of protein tyrosine kinases and protein tyrosine phosphatases. LÄS MER

5. 4. The second wave : the Urak Lawoi after the tsunami in Thailand

   Författare :Ann-Charlotte Granbom; Christer Lindberg; Thomas Malm; Peter Ian Crawford; Sweden Lund University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Urak Lawoi; Chao Ley; sea nomads; sea gypsies; sea people; Thailand; disaster; vulnerability; resilience; tourism development; land policies; Indigenous people; Religion; Urak Lawoi; Turismvetenskap; Tsunami; landrättigheter; Thailand; Havsnomader; ursprungsfolk; visuell antropologi; havsfolk; sårbarhet; religion;

   Sammanfattning : Urak Lawoi är en ursprungsbefolkning i Andamansjön som bl.a. bor på kända turistöar som Phuket, Phi Phi, Ko Lanta Yai och Ko Lipe utanför Thailands västkust. Deras språk och kultur skiljer sig från övriga thailändares, inte minst ifråga om kunskap att navigera på havet. LÄS MER

7. 5. Cases of coupled vibrations and prametric instability in rotating machines

   Författare :Jean-Claude Luneno; Ilmar Santos; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållfasthetslära; Solid Mechanics;

   Sammanfattning : The principal task in this research project was to analyse the causes and consequences of coupled vibrations and parametric instability in hydropower rotors; where both horizontal and vertical machines are involved. Vibration is a well-known undesirable behavior of dynamical systems characterised by persistent periodic, quasi-periodic or chaotic motions. LÄS MER
