  2. 11. On Inter-bar Currents in Induction Motors with Cast Aluminium and Cast Copper Rotors

    Author : Alexander Stening; Chandur Sadarangani; Ola Aglén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Induction motors; Inter-bar currents; Copper rotors; Aluminium rotors; Starting torque; Asynchronous torques; Starting current; Stray losses; Electrical engineering; electronics and photonics; Elektroteknik; elektronik och fotonik;

    Abstract : This thesis presents a study of the effects of inter-bar currents on inductionmotor starting performance and stray-load losses. The work is focused on theperformance differences between aluminium and copper casted rotors.A method to predict the stator current when starting direct-on-line isdeveloped. READ MORE

  4. 12. Structure studies of membrane associated proteins by transmission electron microscopy

    Author : Zuoneng Wang; Carsten Mim; Anna Sundborger Lunna; KTH; []
    Keywords : peripheral membrane protein PMP ; BAR protein; membrane curvature; actin dynamic; transmission electron microscopy; liposomes; Technology and Health; Teknik och hälsa;

    Abstract : Cell membranes need to change their shapes during many cellular processeslike protein trafficking, cytokinesis and membrane homeostasis. The lattershuttles lipids, synthesized in the endoplasmic reticulum, to all membranouscompartments. READ MORE

  5. 13. RICH-1, a Multifunctional RhoGAP Domain-containing Protein, Involved in Regulation of the Actin Filament System and Membrane-trafficking

    Author : Ninna Richnau; Pontus Aspenström; Carl-Henrik Heldin; Bengt Hallberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Cell and molecular biology; Rho GTPase; RhoGAP; actin; BAR domain; membrane-trafficking; formin homology proteins; Cell- och molekylärbiologi; Cell and molecular biology; Cell- och molekylärbiologi;

    Abstract : The Rho GTPases, which are related to the Ras family of proto-oncogenes, have been found to have important roles in regulating the morphogenic and migratory properties of eukaryotic cells. In addition, these proteins have been shown to regulate aspects of cell signaling, cell growth, cell division and cell survival. READ MORE

  6. 14. Improving Machining System Performance through designed-in Damping : Modelling, Analysis and Design Solutions

    Author : Lorenzo Daghini; Cornel Mihai Nicolescu; Miroslav Píška; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machining performance; Cutting stability; Passive damping; High Damping Interface; Boring bar; Turret; SRA - Production; SRA - Produktion;

    Abstract : With advances in material technology, allowing, for instance, engines to withstand higher combustion pressure and consequently improving performance, comes challenges to productivity. These materials are, in fact, more difficult to machine with regards to tool wear and especially machine tool stability. READ MORE

  7. 15. A Passing Power : An Examination of the Sources for the History of Aram-Damascus in the Second Half of the Ninth Century B.C

    Abstract : Much has been written about the kingdom of Aram-Damascus, and if one considers the scarcity of the source material, one could almost say: too much! One of the results of this study is that our historical sources do not support such an extensive history of this kingdom as some scholars have written. The study is a thorough examination of both textual and archaeological sources for the history of the kingdom of Aram-Damascus. READ MORE
