1. 16. Analysis of entry phase in intermittent machining

   Författare :Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Cutting forces and vibrations are essential parameters in the assessment of a cutting process. As the energy consumption in the machining process is directly affected by the magnitude of the cutting forces it is of vital importance to design cutting edges and select process conditions that will maintain high tool performance through reduced energy consumption.

3. 17. Possibilities of CO2 emission reduction : process integration analysis and carbon trading schemes

   Författare :Chuan Wang; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Engineering;

   Sammanfattning : Climate change is one of the greatest challenges faced by today's society. With more evidence from scientists, the need to manage greenhouse gas emissions has been increasing in response to international climate change negotiations. LÄS MER

4. 18. Regulation of CDK dephosphorylation in mitotic entry

   Författare :Arne Lindqvist; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Cell cycle progression is orchestrated by the activity of a Cyclin dependent kinase (Cdk) in complex with a Cyclin. The key regulator of early mitotic events is the Cyclin B1/Cdk1 complex. In G2, Cyclin B1/Cdk1 is kept inactive by phosphorylation in the active site of Cdk1. LÄS MER

5. 19. Inclusion Behaviour under a Swirl Flow in a Continuous Casting Process

   Författare :Yang Ying; Pär Jönsson; Dong-Yuan Sheng; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inclusion behaviour; swirl flow; rotating magnetic field; electromagnetic swirl flow generator; full type; half type; submerged entry no zzle; mold;

   Sammanfattning : A swirl flow generated in a submerged entry nozzle (SEN) can effectively improve a flow pattern and heat transfer in a continuous casting process by using the methods of “swirl blade type” and “electromagnetic type”. In order to obtain a further in-depth understanding with respect to the effect of a swirl flow on a continuous casting process, the inclusion behaviour in a SEN and a mold was studied in the present work.

7. 20. Edge Geometry Effects on Entry Phase by Forces and Vibrations

   Författare :Adnan Agic; Tomas Beno; Jan-Eric Ståhl; Mahdi Eynian; T.H.C. Childs; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Entry; Cutting force; Cutting edge geometry; Acceleration; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Intermittent machining is in general strongly related to the large impacts in the entry phase and related vibrations. The influence of the impact forces and vibrations on the cutting process is dependent on workpiece material, structural properties of the tool-workpiece system, cutting edge geometries and cutting parameters.
