   Sammanfattning : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. LÄS MER

5. 9. Drying of iron ore pellets : analysis with CFD

   Författare :Anna-Lena Ljung; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Strömningslära; Fluid Mechanics;

   Sammanfattning : Iron ore pellets are a highly refined product and for companies such as LKAB it is important to constantly improve the pelletization in order to enhance production and improve product quality. A long term goal has been established to develop and considerably refine tools and techniques with which the drying zone of a pelletizing plant can be optimized. LÄS MER

7. 10. Heavy-Duty Vehicle Platooning : Modeling and Analysis

   Författare :Qichen Deng; Gunnar Flötteröd; Wilco Burghout; Clas Rydergren; KTH; []
   Nyckelord :Transportvetenskap; Transport Science;

   Sammanfattning : Coupled with the growth of world economy, the demand for freight transport has escalated and will continue to do so. As the traffic intensity increases, the pressure on infrastructure, energy usage and environment becomes higher than ever. Meanwhile, the number of traffic accidents is also increasing year by year as a result. LÄS MER
