2. 6. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach

   Author : Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

   Abstract : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. READ MORE

4. 7. Molecular and phenotypical toxicological effects of environmental pollutants and their mixtures : A mechanistic approach

   Author : Greta Nilén; Steffen Keiter; Maria Larsson; Nikolai Scherbak; Magnus Engwall; Malin Celander; Örebro universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Environmental pollutants; mixtures; soil; zebrafish; Danio rerio; behavior; gene expression; lipidomics; image analysis; PCB126; PFOS; B[a]P; Arsenic; risk assessment;

   Abstract : Current environmental risk assessment of polluted sites primarily relies on single compound evaluation. However, in the environment, organisms are often exposed to complex mixtures of pollutants. READ MORE

5. 8. Implementing Community Based Re/habilitation in Uganda and Sweden : A Comparative Approach

   Author : Charlotte Persson; Masoud Kamali; Rafael Lindqvist; Mittuniversitetet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; International Social work; Social Justice; Disability; Travelling Ideas; Implementation; Community Based Rehabilitation;

   Abstract : In our global world, ideas in general and social work models in particular are spread and implemented in a variety of socioeconomic, political and cultural contexts, generating different outcomes. Many ideas and services launched in different countries by international organisations or governments in order to bring social justice to marginalised and oppressed groups, such as people with disabilities, have been criticised for not reaching or involving those such services aim to serve.

6. 9. Draw control strategy for sublevel caving mines : A holistic approach

   Author : Gurmeet Shekhar; Håkan Schunnesson; Anna Gustafson; Jesper Martinsson; Laeeque Daneshmend; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Draw control strategy; sublevel caving SLC ; loading process; draw point; caving operation; Bayesian statistics; probability models; economic models; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

   Abstract : Sublevel caving is an underground mass mining method used for extracting different types of ores from the earth crust. Mines using sublevel caving (SLC) as the primary mining method are generally highly mechanized with standardized and independent unit operations. READ MORE

7. 10. Modelling phase separation in Fe-Cr alloys : A continuum approach

   Author : Thomas Barkar; John Ågren; Nele Moelans; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

   Abstract : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. READ MORE
