1. 36. Interactions between cadmium and micronutrients in pregnant and lactating women

   Författare :Maria Kippler; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Cadmium; Iron; Manganese; Calcium; Zinc; Micronutrients; Pregnancy; Breast milk; Placenta; Metallothionein;

   Sammanfattning : The heavy metal cadmium is a widely dispersed environmental pollutant that has no biological function in the human body and is known to cause several adverse health effects, mainly on kidneys and bone and the endocrine system. Little is known about effects in early life. LÄS MER

3. 37. Numerical modeling of coupled thermo-hydro-mechanical processes in geological porous media

   Författare :Fuguo Tong; Lanru Jing; Chin-Fu Tsang; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermo-hydro-mechanical processes; Porous geologicalmedia; Numerical modeling; FEM; Multiphase flow; Effective thermal conductivity; Water retention curve; Radioactive waste repositories; Bentonite; ; Geoengineering; Geoteknik;

   Sammanfattning : Coupled Thermo-Hydro-Mechanical (THM) behavior in geological porous media has been a subject of great interest in many geoengineering disciplines. Many attempts have been made to develop numerical prediction capabilities associated with topics such as the movement of pollutant plumes, gas injection, energy storage, geothermal energy extraction, and safety assessment of repositories for radioactive waste and spent nuclear fuel.

4. 38. Treatment conditions for the removal of contaminants from road runoff

   Författare :Magnus Hallberg; Gunno Renman; Jiri Marsalek; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dissolved matter; filter bed; particulate matter; sedimentation; suspended solids; Environmental engineering; Miljöteknik;

   Sammanfattning : The pollutant load in road runoff is related to traffic densities and road maintenance activities. Inurbanised areas treatment of road runoff is common and often considered necessary. The pollutantsare partitioned between the particulate and dissolved matter. However, the contaminantstend to have an affinity to the particulate material. LÄS MER

5. 39. An evaluation of sources contributing to urban runoff pollution

   Författare :Alexandra Müller; Maria Viklander; Helene Österlund; Jiri Marsalek; Shirley E. Clark; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stormwater quality; Pollution sources; Building surface materials; Traffic activities; Source identification methods; VA-teknik; Urban Water Engineering; Centrumbildning - Centrum för dagvattenhantering DRIZZLE ; Centre - Centre for Stormwater Management DRIZZLE ;

   Sammanfattning : Urban runoff is a significant pathway for the transport of diverse substances from the urban environment to receiving water bodies. Many of these substances are pollutants of environmental concern with potentially harmful effects on aquatic life. LÄS MER

7. 40. RhPt and Ni based catalysts for fuel reforming in energy conversion

   Författare :Angélica Viviana González Arcos; Lars J. Pettersson; Klas Engvall; Anker Jensen; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; RhPt bimetallic catalysts; Ni catalysts; ceria-zirconia; potassium tungsten bronze; zirconium dioxide; autothermal reforming; biodiesel; diesel; sulfur; deactivation; tar reforming; steam reforming; biomass gasification; auxiliary power units; naphthalene; Chemical Engineering; Kemiteknik;

   Sammanfattning : Although current trends in global warming are of great concern, energy demand is still increasing, resulting in increasing pollutant emissions. To address this issue, we need reliable renewable energy sources, lowered pollutant emissions, and efficient and profitable processes for energy conversion. LÄS MER
