  2. 1. Modeling internal deformation of salt structures targeted for radioactive waste disposal

    Author : Zurab Chemia; Hemin Koyi; Harro Schmeling; Ian Alsop; Uppsala universitet; []
    Keywords : salt; diapir; anhydrite; deformation; entrainment; numerical modeling; rheology; sinking; Gorleben;

    Abstract : This thesis uses results of systematic numerical models to argue that externally inactive salt structures, which are potential targets for radioactive waste disposal, might be internally active due to the presence of dense layers or blocks within a salt layer.The three papers that support this thesis use the Gorleben salt diapir (NW Germany), which was targeted as a future final repository for high-grade radioactive waste, as a general guideline.

  4. 2. Production and Perception of Pauses in Speech

    Author : Kristina Lundholm Fors; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; pauses; dialogue; entrainment; turn taking;

    Abstract : Silences can make or break the conversation: if two persons involved in a conversation have different ideas about the typical length of pauses, they will face problems with turn taking. Pauses occur in conversation for a number of reasons, for example for breathing, thinking, word-searching and turn taking management. READ MORE

  5. 3. Study of gas fuel jet burning in low oxygen content and high temperature oxidizer

    Author : Magnus Mörtberg; Wlodek Blasiak; David G. Lilley; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; combustion; entrainment; jet in crossflow; PIV; ICCD; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : During the past decade, new advanced combustion systems that share the same basic concept of using a substantially diluted and high-temperature oxidizer in the reaction volume have gained a great deal of interest regarding their application in industrial and power systems. These novel combustion technologies have proved to offer significant benefits compared to traditional combustion techniques. READ MORE

  6. 4. A study of mold flux entrapment and gas entrainment in an ingot casting process

    Author : Jun Yin; Mikael Ersson; Pär Jönsson; Yogeshwar Sahai; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mold flux entrapments; CFD; Gas entrainment; Ingot casting process; Uphill teeming process; Side teeming process; Numerical simulation; Non-metallic inclusions; Metallurgical process science; Metallurgisk processvetenskap; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The focus of this work is to study the gas entrainment and mold flux entrapments during the ingot filling process based on physical and numerical modelling.The formation of the free surface was investigated in the uphill teeming method, which illustrates a dynamic change at a quasi-steady state.

  7. 5. Alterations in circadian entrainment : translational value in major depression

    Author : Frederik Elberling; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Adverse conditions of different origin occurring during development can have a negative impact on the nervous system and increase risk for the onset of mental disorders. In mice prenatal exposure to excess glucocorticoids (GC) leads to late onset depression-like behaviour in males which is preceded by alterations in circadian entrainment. READ MORE
