  4. 2. Diabetes, metformin and gastric adenocarcinoma

    Author : Jiaojiao Zheng; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Diabetes may increase the risk and mortality of certain cancers, but its association with gastric adenocarcinoma is not clear. On the other hand, metformin, a first-line treatment for diabetes, may reduce cancer risks and improve cancer-related survival, but these associations have not been confirmed in gastric adenocarcinoma as well.

    Abstract : This thesis is aiming at coolability assessment of particulate debris beds formed in hypothetical severe accidents of Nordic boiling water reactors (BWRs) which may employ either lower drywell flooding or control rod guide tubes (CRGT) cooling as severe accident management strategies. For this purpose, quench and cooling limit (dryout) of debris beds after their formation from fuel coolant interactions were investigated by numerical simulations using the MEWA code. READ MORE

  7. 5. Analysis and modelling of plastic bending processes

    Author : Zheng Tan; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : It is well known that anisotropic properties of material allect forming of sheet metals and that non-homogeneous deformation across thickness of a bend gives rise to residual stresses. The interaction between material and process parameters determines, in a very complex manner, the formability of material. READ MORE
