2. 1. Structural elements involved in protein-mediated proton transfer : Implications from studies of cytochrome c oxidase

   Author : Ann-Louise Johansson; Martin Högbom; Peter Brzezinski; Bertrand García-Moreno; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytochrome c oxidase; proton transfer; Biochemistry; biokemi;

   Abstract : Proton transfer is one of the most common reactions in biological systems. During energy conversion inside a cell, proton transfer is crucial to maintain an electrochemical proton gradient across the cell membrane. This gradient is in turn used to e.g. READ MORE

4. 2. Programming Blood Cell Fates. Insights from Direct Lineage Conversion and Development

   Author : Sandra Capellera Garcia; Avdelningen för molekylärmedicin och genterapi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hematopoietic development; Erythropoiesis; Megakaryopoiesis; Direct Lineage Conversion;

   Abstract : Red blood cells (RBC) and platelets constitute the non-immune branch of the hematopoietic system and are responsible for the vital functions of transporting oxygen to the tissues and clotting blood vessel injuries, respectively. These cells are produced during embryonic development and throughout life through a process called hematopoiesis which is tightly regulated by extrinsic and intrinsic factors. READ MORE

5. 3. Accuracy and Delay: An Inherent Trade-off in Cooperative UWB Navigation

   Author : Gabriel Garcia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; positioning; Ultra-wideband; navigation; MAC delay; localization.; S-TDMA;

   Abstract : Location-aware applications and wireless sensor networks are becoming essential in our daily lives from a commercial, and public perspectives. The need of localization information to drive the applications is a key requirement. New technologies have emerged to tackle the problem of the limitations of the Global Positioning System (GPS) solutions. READ MORE

6. 4. Tailoring of Contacts on Silicon Carbide - Procedures and Mechanisms

   Author : S. A. Perez-Garcia; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; interfacial reaction; metallic contacts; Silicon carbide; silicides; XPS.;

   Abstract : Silicon carbide (SiC) exhibits very good electrical, thermal, chemical and mechanical properties which make it suitable for the next generation of wide band gap electronic devices, where silicon (Si) cannot be used due to its limitations with respect to the mentioned properties. Nickel (Ni) and Tantalum (Ta) are among the metals used for the contact formation. READ MORE

7. 5. Synthesis and applications of low silica zeolites from Bolivian clay and diatomaceous earth

   Author : Javier Gustavo Garcia Mendoza; Johanne Mouzon; Niklas Hedin; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zeolites; Synthesis; clay; diatomite; adsorption; ion exchange; Chemical Technology; Kemisk teknologi;

   Abstract : The aim of the present work was to develop synthesis routes to produce synthetic zeolites with industrial attractiveness from non-expensive Bolivian raw materials, such as clays and diatomite. In particular, the work was focused on the synthesis of low-silica zeolites with the LTA and FAU structures. READ MORE
