  1. 21. Security and Efficiency Tradeoffs in Multicast Group Key Management

    Författare :Claudiu Duma; Nahid Shahmehri; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Key management; Multicast communication; Security-efficiency tradeoffs; Collusion resistance; Push-oriented approaches; Computer science; Datavetenskap;

    Sammanfattning : An ever-increasing number of Internet applications, such as content and software distribution, distance learning, multimedia streaming, teleconferencing, and collaborative workspaces, need efficient and secure multicast communication. However, efficiency and security are competing requirements and balancing them to meet the application needs is still an open issue. LÄS MER

  3. 22. Nanostructured Ceramics - Synthesis and Understanding

    Författare :Farnaz Ghajeri; Wei Xia; Freddy Kleitz; Uppsala universitet; []
    Nyckelord :Material Science; Nanoporouse Silica; Calcium Phosphate; Synthesis; Characterization; Adsorption; Teknisk fysik med inriktning mot materialvetenskap; Engineering Science with specialization in Materials Science;

    Sammanfattning : During the last years, nanostructured ceramics have been favored for use in the industry due to their beneficial properties. For example, calcium phosphate ceramics with their biocompatible and bioactive characteristics are beneficial in biomedicine. LÄS MER

  4. 23. Components controlling vesicle trafficking and regulated exocytosis in pancreatic beta-cells

    Författare :Slavena Andrea Mandic; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Regulated exocytosis is a sophisticated, well-organized and conserved multistage process underlying release of both neurotransmitters and hormones. Exocytosis is mediated by SNARE proteins that act at the center stage by forming a SNARE complex with the intrinsic capability to execute membrane fusion. LÄS MER

  5. 24. Establishing the mechanistic basis of sugar transport

    Författare :Abdul Aziz Qureshi; David Drew; Magnus Wolf-Watz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; membrane transport; transport energetics; nucleotide-sugar transporters; glucose transporters; malaria; cancer; Biochemistry; biokemi;

    Sammanfattning : Sugar is a vital molecule required for cell viability and homeostasis. Sugar is important for metabolic energy, energy storage, signaling, structure and osmolyte regulation. Transport of sugar represents an important physiological process. LÄS MER

  7. 25. Structure-Function Relationships in RuII Complexes with Unconventional Ligands: Photophysical and Photochemical Studies

    Författare :Joachim Wallenstein; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; structure-function relationship; spectral component analysis; photochemistry; RuII complexes; photoreaction; hole-transfer;

    Sammanfattning : The rich photophysics, photochemistry and electrochemistry of RuII complexes have attracted intense research interest in widely disparate fields. A large portion of the studied and applied complexes are derived from the archetypical [Ru(bpy)3]2+ (bpy is 2,2’-bipyridine), which absorbs in the visible region, displays a long lived (~1 μs), emissive metal-to-ligand charge transfer state, and shows reversible electrochemistry in both the ground and excited state.
