    Sammanfattning : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. LÄS MER

  3. 2. Interference Cancellation for DS/CDMA Systems in Flat Fading Channels

    Författare :Ann-Louise Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mixed modulation; direct-sequence code division multiple access DS CDMA ; multiuser detection.; multiple data rates; parallel channels; multicode; interference cancellation;

    Sammanfattning : This thesis investigates interference cancellation in direct-sequence codedivision multiple access (DS/CDMA) systems that support multiple data rates.Two approaches for implementing multiple data rates are considered. Oneis the use of mixed modulation. The second is the use of parallel channels. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Successive Interference Cancellation in DS-CDMA Systems

    Författare :Ann-Louise Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; group-wise detection; direct-sequence code division multiple access DS-CDMA ; multiuser detection; multirate schemes; weighted cancellation; successive interference cancellation;

    Sammanfattning : There is every indication that direct-sequence code division multiple access (DS-CDMA) will be one of the multiple access schemes for the third generation wireless mobile systems. CDMA is a flexible multiple access method suitable for supporting many new services (speech, data, video, etc), which are becoming increasingly important for mobile communications. LÄS MER

  7. 5. Settling disputes at the World Trade Organization

    Författare :Louise Johannesson; Magnus Lodefalk; Hildegunn Kyvik Nordås; Dan Johansson; Kara M. Reynolds; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; World Trade Organization; trade policy; trade disputes; dispute settlement; causality; panels; developing countries; panels; international trade;

    Sammanfattning : This cumulative dissertation consists of five self-contained essays, all of which are closely focused around issues that concern the WTO dispute settlement mechanism (DSM). In Essay 1, we describe salient features of the DSM using a unique data set. LÄS MER
