1. 1. Sedimentological and Hydrological Investigation of Mosul Dam Reservoir

   Författare :Issa E Issa; Ian Foster; Luleå tekniska universitet; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Area-storage capacity curves; Area reduction method; Bathymetric survey; Losing storage capacity; Mosul dam; Reservoir bottom morphology; Reservoir sedimentation; Sediment trap efficiency; Useful life of dam; Soil Mechanics; Geoteknik;

   Sammanfattning : Reservoir sedimentation is the main problem that directly affects the performance of dams due to the reduction in the storage capacity of their reservoirs. Monitoring the storage capacity of reservoirs is an important issue for the planners, designers and operators of the dams. LÄS MER

3. 2. Exploring Monoclonal Antibody Action Against the Group A Streptococcal M Protein

   Författare :Sebastian Wrighton; Infektionsmedicin; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; group A streptococcus; Streptococcus pyogenes; fibronectin; phagocytosis; innate immunity; antibodies; adaptive immunity;

   Sammanfattning : Group A Streptococcus (GAS) is a significant human pathogen that has developed multipleimmune evasion mechanisms to counter the host immune response. One of these mechanisms involvesthe production of the M protein, which, amongst other things, acts as an anti-phagocytic factor and canbind host proteins. LÄS MER

4. 3. Foreign Investment Decision-Making in Transition Economies

   Författare :Olga Golubeva; Julio De Castro; Stockholms universitet; []
   Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; FDI; transition economy; initial motivation or reasons for FDI; capital budgeting methods and investment decision criteria; investigation of investment climate and information collection methods; risk assessment and risk reduction measures; decision-making models; case studies; survey method; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies; investment decision criteria; Eriksson; Vattenfall; servey method; företagsekonomi; Business Administration;

   Sammanfattning : The purpose of this project is to describe and explain the foreign investment decision process in the uncertain and turbulent environment of transition economy. By getting an in-depth understanding of how decision-making works in the environment of transition economy, the study intends to contribute to the development of business administration theory in the area of foreign investment decision-making, particularly its application in the turbulent and uncertain world.

5. 4. NOx Storage and Reduction Catalysts. Reduction with Hydrogen and the Influence of Water and Carbon Dioxide

   Författare :Anna Maria Lindholm; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NSR catalyst; Pt Ba Al; H2O; CO2; Pt Al; NOx reduction; H2; NH3 formation; NOx storage; Lean NOx Trap; N2O formation; kinetic modeling; Pt Si;

   Sammanfattning : Environmental concern has increased over the past several years and resulted in stringent emission legislation on NOx, CO, and hydrocarbon emissions from automobile exhausts. Moreover, the demands to improve the fuel efficiency of engines and to lower the CO2 emissions have increased, and a way to meet this is by using lean burn engines which operate with oxygen excess.

7. 5. Specific surface area of some minerals commonly found in granite

   Författare :Isabelle E. Dubois; Maria E. Malmström; Bo Strömberg; KTH; []
   Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Granite; Mineral; Surface area; BET; Sorption; Particle size;

   Sammanfattning : The specific surface area, determined by the BET method, is a parameter often used to scale results of mineral studies of surface reactions in terms of rate and capacity to the field scale. Such extrapolations of results from small-scale laboratory experiments to the field-scale are important within many environmental applications. LÄS MER
